The Okey 20 HP Model L-7 was a model of the US passenger car manufacturer Okey Motor Car Company in Columbus , Franklin County , Ohio .

Model history

The Only Motor Car Company was founded in 1905 or January 1907, depending on the source. Your problem has been under capitalization from the start.

Founder Perry Okey had manufactured his first automobile in 1896, at the age of 16, and experimented until 1901.

This was followed by limited production on a craft basis. The model with a water-cooled single - cylinder four-stroke engine had a planetary gear and chain drive . It made 14 bhp (10 kW) at 1000 revolutions per minute and had a top speed of 35 mph (50 km / h). A successor with a two-cylinder two-stroke engine is documented, but there seem to have been other, undocumented models.

technology

The L-7 is the only model from the manufacturer for which the key data is available. It is known that the vehicle was a right-hand drive and - probably in the only body variant offered as a runabout - weighed 1301 lbs (590 kg). The illustration suggests that the vehicle had carbide or oil lamps typical of the time .

engine

Three cylinder two-stroke engine of the 20 HP Model L-7.

Perry Okey constructed his motors even one was in the L-7, as in the previous 14 HP. Water-cooled three-cylinder - two-stroke engine installed. The displacement is, depending on the source, 140.3 or 140.4 ci (2298 or 2301 cm³), the latter being more precise, as it is obviously not based on rounded values for bore (104.8 mm) and stroke (88, 9 mm). There is no information on the type of flushing and ignition system . Okey also produced the carburetors himself. He held a patent for a carburetor with a ring-shaped float, needle valves and an automatic valve between the carburetor and the engine for additional air supply. The mode of operation is known from a larger engine with a displacement of 226.2 ci (3707 cm³). However, there is no evidence that this carburetor or a variant of it was also used in the L-7.

The engine output is specified with 22 bhp (16.4 kW) at 1300 rpm; the ALAM rating is 20.4 HP. This is a calculated, unmeasured value that was also used to calculate the tax formula, for example in the UK. The ALAM ( Association of Licensed Automobile Manufacturers ) was the association of motor vehicle manufacturers licensed under the Selden patent . In 1903 he first published standards for motor vehicles in the USA.

Power transmission

The power was transmitted to the rear axle via a planetary gear and a drive shaft .

Chassis and suspension

Little information is available on the chassis and the few available are contradictory. What is certain is that Okey vehicles were right-hand drive . The wheelbase is different with 90 inches (2286 mm) resp. 92 inches (2337 mm) stated. The track width was 56 inches (1422 mm) on both axles.

Images of the L-7 show that semi - elliptic leaf springs were used all around . Wooden artillery wheels with 12 spokes and brake drums on the rear axle are also clearly visible . Back then, two brakes that worked independently of each other were common. They were usually operated with a brake pedal and lever each; because there was no standard for this, different solutions can be found. The foot brake pedal often acted on the inner shoe brakes on the rear axle; the handbrake then acted on an external shoe brake , which was attached either to the axle, to the gearbox or to the differential . Brakes on the front wheels did not take hold until after the First World War.

The dimensions of the wheels are 34 × 3, respectively. Called 34 × 3½. However, it is possible, and was quite common, for the wheelbase and wheel size to be changed while a model was in production.

body

The only known body version is a two-seat runabout with a barrel-shaped fuel tank behind the seats. Such vehicles, especially those with a minimalist body, are called speedsters .

Market position

The Okey Motor Car Company was a typical regional vehicle manufacturer. Handicraft businesses like this disappeared with the emergence of the national distribution networks of the major manufacturers and the mass production that had already started before the Ford Model T , for example at Oldsmobile or Rambler.With a price of US $ 1400, the L-7 belonged to the middle class at the time . A - albeit quite crude - highwheeler cost from around US $ 350, -, the Oldsmobile Curved Dash , which is structurally reminiscent of the earlier Oakey, US $ 650, -.

Remarks

↑ The ALAM rating is calculated: cylinder bore ² × number of cylinders; the result is divided by 2.5. A conversion into bhp or kW is not possible. SAE-PS were later developed from this formula . A rating table was also derived from the formula.
