The 1915 Model T Ford model year is difficult to pinpoint. There was considerable overlap in the new 1915 style and the older 1914 models. In general, we consider the 1915 model year to have begun in about September 1914 for the closed cars, and January 1915 for the open models.
The new Sedan, with the center door, was introduced in September 1914, and the Coupelet with the folding top shortly after. The new touring and roadster bodies, though, were introduced at the Highland Park plant in January 1915. Many, if not all, of the Ford assembly plants continued making the 1914 style open cars until perhaps April 1915, so there is considerable overlap in the production of the 1914 and 1915 open cars. The new touring and runabouts were first shipped from Highland Park in February 1915. At the same time, sample bodies were shipped to the branches; these bodies to be used as models for the changeover to the new style.
The Sedan and Coupelet, though, were the harbingers of the new Ford line for 1915. While retaining the straight front fenders of the 1914s, the rear fenders were now curved to follow the wheel outline (roughly), and the cowl section was now metal and flared to join the body to the hood, replacing the flat wooden board which had been used since 1909.
Lamps
Along with the new styling came another modification to the Ford car:
electric lights. While there were examples of early 1915s with gas lamps, the
standard issue was electric headlamps, powered by the engine magneto. Not
wanting to startle the public too much, though, the side and tail lights
continued to be of the oil (kerosene) type, although they were of a new and
cheaper design.
Since the 1914 style open cars continued into 1915, and all apparently used the 1914 style black and brass gas and side/tail lamps, there was most certainly a period of mixed production. Early photos have been seen of 1915 cars with the gas lamps. Factory photos of 1914 cars with electric lamps, though, are another matter. The factory issued a letter on January 12, 1915, which advised that the crossover tube on the radiator, for the gas lamps, was being discontinued as all cars now have electric lights. This would lead one to believe, then, that the 1914 style cars then being assembled would have had electric lamps. It is believed that all of the 1914 style cars used gas lamps, probably using up the remainder of the radiators with the gas tube, and that where a photo shows the electric type, someone other than Ford made the switch.
The first electric headlamps were designed to mount on the same forks that were used for the gas lamps. By early 1915, though, the standard design with the riveted-in-place post was standard equipment. The earliest 1915 electric headlamps, used on the closed cars in late 1914, were somewhat different from the later. Made by Edmond and Jones, they were a little larger than the standard, having lenses 8-5/8 inches in diameter (instead of the standard 8-1/8inches). All early 1915 lamps had brass rims, but these earliest lamps had rims that were thicker. The early side lamps, too, had larger lens and brass trim.
Electric headlamps, and oil tail and side lamps, with brass rims were standard equipment on the 1915s. By about June of 1915, the brass trim was discontinued on all lamps. The bulbs of the headlamps were wired in series, and connected to the magneto through a push-pull switch on the firewall just to the right of the coil box.
The side and tail lamps were of a new design. Not only were they cheaper, the side lamps could be interchanged from side to side. The tail lamp had a large red lens on the door, and a clear lens on the side facing the license plate (towards the center of the car). Both types mounted by means of a stud on the rear side.
Magneto
On September 14, 1914, beginning with engine number 578,042, Ford began using
the new magneto with the 3/4-inch magnets. Not only was this new magneto able to
supply the additional current for the headlights, its design was such that it
reduced the dead spots in the spark lever setting that were so
noticeable in the earlier design. This was accomplished by also using larger and
oval-shaped pole pieces in the magneto coil. Other than casting a
notch in the base plate to clear the starter shaft in 1919, the
magneto remained relatively unchanged through the balance of Model T production.
The New Sedan (Also see notes at the end of this file)
The new Sedan set the style for the familiar centerdoor style
which was used until mid-1923. However, the 1915 Sedan had an entirely different
body than that used on the later models. It was made of aluminum panels, with a
one-piece lower rear panel (from door to door, with no seams at the rear). The
body sat a bit lower on the chassis, and required a different splash apron and
rear fenders than the other models. The rear fenders were fastened directly to
the body instead of to the usual fender irons. The windshield was a rather
complicated three-section affair, with top sections that folded inward and
outward.
Upholstery was beautiful when compared with the other Ford cars. The front seats were individual bucket style, with the passenger seat folding forward to allow better access to the drivers seat. Neither of these seats could be praised for comfort, with the passenger seat being downright uncomfortable, at least to this writer. The rear seat, however, was luxurious, with the rear cushion extending around to add side support. The upholstery material was a fancy broadcloth, with elaborate trimming. The Coupelet, while using some of the Sedans upholstery styling, used leather on the seats and imitation leather on the door panels. As in all the closed cars, the cowl area was covered with imitation leather.
The gasoline tank on the sedan was located under the rear seat. Being just a few inches above the frame, and about six feet to the rear of the carburetor, fuel flow was a real problem. This problem apparently became known soon after the introduction of the car. During late 1914 Ford advised changing the fuel line to 5/16-inch and then, in December, announced a new and longer intake manifold which lowered the carburetor. The Kingston carburetor was recommended, since it was claimed to have a better fuel flow than the Holley. The tank was moved to its position under the drivers seat with the 1916 models (which also used a new standard body).
The Coupelet (Also see notes at the end of this file)
The Coupelet was the first Ford convertible. The top could be lowered but the
doors had glass windows which could be adjusted by means of a strap, as in the
Sedans. The top was leather in 1915, then changed to leatherette later in the
year. Seats were apparently full leather, with imitation leather door panels.
The top was lined with a cloth material in gray, trimmed with a lace similar to
that used in the sedan. The gas tank on the Coupelet was in the rear deck, and
was at least initially, the standard round tank. By 1916, though, the tank was
changed to the square tank, still located in the deck, that was also used on the
1916 sedan (under the drivers seat).
The early Coupelets were quite blind since the top sides wrapped around the seat. The top was modified in later production (typical of the 1916 Coupelets) to have a small window on each side quarter.
The Town Car
The Town Car was modified to conform to the new styling. This model had added
rear passenger space but at the expense of the drivers comfort. The front
seat was closer to the steering wheel, and its back rest was quite upright and
poorly padded. Portly chauffeurs had a real problem! The passenger compartment
could seat five in a pinch (and it would have been a pinch), seating three in
the seat and using the two folding jump seats. Upholstery in the Town Car was
full leather on the front and rear seats, with either real or imitation leather
door panels. The jump seats were upholstered with imitation leather. The top was
imitation leather. Inside the top was lined with a gray cloth, trimmed with a
lace similar to that used in the sedans and coupes. The kick panel of the rear
seat was covered with a rug-like material.
The Town Car is interesting. Fords existing records show that none were built during fiscal 1915 (August 1914 to August 1915). Also, Ford generally referred to cars built during a fiscal year as models of that year. 1915 is certainly an exception to this rule, since the cars built during 1914, except for the Sedan and Coupelet, were definitely 1914s. Apparently there were enough unsold 1914 Town Cars to last through the first part of calendar 1915, and the 1915 models were actually built in fiscal 1916 (August 1915 to August 1916). It is also possible the existing Ford records (a relatively recent compilation) are in error. Interestingly, though, of the existing 1915 Town Cars we know of, all are dated late in the year.
The closed cars did not sell well. According to Ford Archives figures, just 989 Sedans, 2417 Coupelets, and no Town Cars were produced in fiscal 1915. In February 1915 Ford announced that they would discontinue all advertising because they were backlogged some 50,000 cars. In the same letter, though, they noted that there were plenty of the closed models available and that more effort should be made (by the dealers) to move them.
The Open Cars
The early open models continued the basic bodies of the 1914 cars except for
the change in the cowl, windshield, and rear fenders (and other lesser details).
The bodies on these models were the same width as the 1914s, and used a
slightly wider top bow than the usual 1915 (and later) style. Early in the year,
though, the bodies were modified, eliminating some of the wood framing and
substituting sheet metal, notably in the seat frames. The new body, in the
touring car, could be identified by the rivet on the side panel just
ahead of the rear door. This rivet is actually the head of a
carriage bolt which tied the side panel and the seat frame together.
The cowl section varied, apparently due to a different manufacturer. One cowl section was an assembly of top, side and front panels which were riveted together, with the rivets clearly visible from inside the car, along the top edge. The other cowl was similar, if not identical, to that used in the later bodies in that it was a three-piece affair with a top, and two sides. The front panel was integral with the top section, and there were no rivets. Both of these cowl types appeared at the same time, and both were used into 1916. (The riveted type was apparently dropped in later 1916 but were not certain.)
Open car upholstery was all imitation leather. The seat bottoms had a diamond-sewn pattern, with the backs in the plain ribbed style. Only the front roll of the arm rest was real leather. Door and side panels were cardboard, covered and trimmed with an imitation leather.
Windshields
The windshield on the open cars now stood upright, supported at the cowl by
two forged brackets which also supported the side lights. These supports were
riveted to the windshield frame, with the rivets going from front to rear.
(After the early 1917 models, the brackets bolted to the frame, with the bolts
on the side.) The frame is black painted steel, and is hinged in the center so
that the top section can be folded back and down. The top and bottom sections of
the windshield were of equal size. The top was supported by straps to the
windshield hinge, as in the earlier models.
Fenders
As mentioned earlier, the rear fenders were now curved to roughly follow the
wheel outline. These fenders were not crowned, however, as were the 1917 and
later type. Early production front fenders were the same as the later 1914 cars,
with four rivets securing the fender iron clamp. Early in the year, though, a
new clamp arrangement appeared which used just three rivets, and this type
remained unchanged through 1916 production. Both fender styles had the front
bill, a feature added in later 1914 production.
Hood
The hood, while in the same pattern as the earlier cars, was now given
louvers. The 1915 hood was initially made of aluminum but by 1916 hoods were
made of steel. The louvers were not added for cooling, although they might have
helped. Rather, they were necessary because of the location of the horn.
Previous cars had the horn outside the hood, mounted on the firewall. With the
new cowl, the horn was placed inside the hood, mounted on the firewall on the
inside of the steering column. With no louvers in the hood it would have been
almost impossible to hear the horn.
Horns
Horns, incidentally, were still of the bulb type in most of the 1915 cars.
The magneto powered horn was announced as an experiment in January 1915 and was
initially installed on 10,000 cars. It was so much better than the bulb type
that it gradually replaced the bulb horn, and by fall of 1915 the magneto horn
was used exclusively. The bulb for the bulb horn was attached to the steering
column, with the air hose entering the passenger compartment through a notch in
the floorboard just to the right of the steering column. There are pictures,
too, of the horn bulb being mounted on the drivers side panel. Is it any
wonder we cant say anything for sure about a Model T?
The button for the magneto horn was located on the top surface of the steering column, just below the gear box, and a metal tube-like piece was added under the column for the horn wire. Early magneto horns had brass-trimmed bells but the later models were black painted steel. There were, of course, variations in the various horns used, due to different suppliers and/or design changes. While it is commonly believed that 1915-16 Fords used a hand operated Klaxon horn, there is no evidence that Ford ever installed such a horn at the factory. Klaxon horns were a very popular accessory, and probably better than the factory equipment.
Tires
1915 was the first year in which Ford began to supply rear tires with a tread
pattern, both types (with and without a tread pattern) being installed depending
on the supply. Tires with treads
were not new, but Ford wanted to continue to the last with the newest. (Brass
radiators, oil lamps, hand cranks, and bulb horns were all obsolete on most cars
by 1915!) A letter dated January 1916 announced that non-skid tires are to
be supplied by U.S. Tire Co. and that the branches were to use up the
smooth tires first.
Rear Axle
1915 was a time for another redesign of the rear axle housings. Evolving
through several major design changes, and many minor ones, they finally got it
right. Interestingly, the new design was very similar to the type
used on the Models N, R and S Fords of 1906-08. The early 1915 models used the
1914 style axle but by April 1915 the new type was standard. This new design
used cast center sections, with straight axle tubes inserted into them; the
standard design used through 1927. The brake backing plates on the 1915 axles,
though, were smooth as on the 1914 type. Reinforcing ribs were added later in
the year. The last of the internal bronze bushings disappeared during the year.
These bushings were in the three spider gears. The bearing surfaces of the
spider were made larger to fit the gears without the bushings.
Transmission
Early in 1915 the foot pedals were made without the usual C, R, and
B cast on their top faces. In place of the letters, the faces now had a
ribbed pattern. By late 1915, though, the ribs were also dropped and the pedals
were perfectly smooth and were to remain so for all future Model T Fords.
The typical transmission cover in 1915 was aluminum, identical to the 1914, with the reinforcing bosses around the bolt holes at the widest part (introduced in about 1913). Sometime during the year, though, the cover was changed to the cast iron style. All 1916s were believed to have had the iron cover.
Beginning on June 17, 1915, a metal disk was installed in the tail shaft of the transmission brake drum in an effort to prevent oil leaks out of the universal joint. This disk was used in all later Model Ts.
Oilers
Minor items, such as the oilers on the spindles and tie rods, were modified.
Initially these oilers were the brass twist-to-open type which had been used for
a number of years. Sometime during the year these were dropped in favor of a
less expensive brass-capped oiler with a man hole like cover. This
cover was held in place with an internal spring. These oilers are not the same
as the more common flip top type used later.
Springs
Springs, front and rear, were of the tapered style in 1915. 1916 production
saw the gradual change to the square-end front springs but the rear springs
remained taper-leaf. Shackles were the two-piece figure-eight type with the
brass oilers, as used in the 1914 models.
Steering Column
A great improvement was made in the steering column assembly. Early
production used the riveted type gear case of the earlier models, but early in
1915 (apparently) the new one-piece gear case appeared, with the pressed steel
quadrant and iron control rods. The gear case is cast bronze and is not plated.
With the addition of the electric horn, a small tube was added to the underside
to cover the horn wire. The steering wheel spider was black-painted cast iron
(forged steel, actually). The wheel rim was wood, and also painted black.
Ignition Coils
With the new and smaller cowl section, the firewall was also smaller. Since
the coil box was mounted there, it was necessary to redesign it in order to
remove the coils. The top of the box was now cut on an angle, allowing the coils
to be tipped forward to clear the top of the cowl. A new box cover was made to
fit. While similar to the later covers, the 1915-16 covers were a one-piece
stamping with rounded covers, rather than the fabricated three-piece affair used
later. The ignition switch on the bulk of the 1915 cars had a black and brass
cover plate. Ultimately this plate was dropped in favor of the plain steel one,
painted black, which had Mag-Off-Bat stamped on the bottom.
Interestingly, on March 24, 1915, Ford issued a letter to its branches which
said, It has been suggested that the left rear door be
eliminated...... and asked for opinions on the matter. Apparently the idea
fell on deaf ears.
One should note that not all bodies of the same style during any year were exactly alike. There was more than one supplier of bodies, and there were variations between the different brands. In June 1915 Ford issued a letter to its branches: Hereafter when ordering body panels for 1915 cars, please give both the car and body numbers. The body number will be found just inside the front door. This number will be preceded by a letter which indicates by whom the body was made. The above information is necessary as panels for bodies made by our various body manufacturers vary somewhat. Incidentally, Ford discontinued noting body numbers in production beginning in May 1915.
As noted above, there is little difference between 1915 and 1916 models, one
year just evolving into the next. In general, the major changes for
1916 cars were:
1. Brass trim on the lamps is dropped in favor of black-painted steel.
2. The ribs on the foot pedals were replaced with the smooth-surface type.
3. The iron transmission cover replaced the aluminum type.
4. The hood is steel rather than aluminum.
5. The horns were all magneto type after October 1915.
6. Brake backing plates all had the reinforcing ribs.
Month/Year | Sedans | Sedan Cost | Coupelets | Coupelet Cost | |
Dec. 1914 | 331 | $577.927 | 801 | $373.95 | |
Jan. 1915 | 441 | $612.215 | 211 | $408.918 | |
Feb. 1915 | 204 | $601.066 | 160 | $398.826 | |
Totals | 976 | 1172 |
There is no cost book for March 1915, but the April book lists
production for both March and April 1915. No sedans or coupelets were produce in
either of those months. In fact, 1915 sedan and coupelet production ends in February
1915 and does not resume until October 1915 (1 coupelet). In November 225 coupelets
were produced and 1 sedan. And in December 213 coupelets and 130 sedans were made.
The cars built in December 1914, January and February 1915 were
the 1915 style without the window in the rear quarters. Cars built in October,
November and December would have been the 1916 style with the rear quarter windows.\br />
Other information I found indicates that all of the 1915 style
sedan and coupelet bodies were manufactured by Fisher Body Company. The bodies arrived
fully painted and upholstered. All Ford had to do to them was to add the side and tail
light brackets and bolt them onto a chassis.
The cost books also revealed that all 1915 style sedan and coupelets
came equipped with a speedometer as standard equipment. All 1916 style sedans and coupelets
did not come with speedometers supplied by Ford. A note in the August 1915 cost book
reads: "Note: Speedometer cost on included; starting in August none were put on cars."
One last note of interest: there were very few open cars built in
January 1915, only 110 torpedos (roadsters) and a mere 36 touring cars. Apparently the body
manufacturers had difficulty forming the curved cowl that was characteristic of 1915 and
later open cars. Touring production recovered in February with 5674 touring cars produced.
