American Machine Manufacturing Company was an American manufacturer of automobiles .

Company history

The company was founded in Detroit , Michigan in 1906 . David Blumenthal was President, Charles C. Simons Vice President, FV Nicol Secretary and Treasurer, and WJ Grant Superintendent. The company hired Paul Arthur as chief engineer. The company initially manufactured vehicle components and engines. In 1907 the production of automobiles began , with the focus on commercial vehicles and only a few passenger cars . The brand name was Commerce . Production ended in 1908.

There was no affiliation with Commerce Motor Car Company , which manufactured motor vehicles with the same brand name.

vehicles

The main product was trucks . Some vehicles could easily be converted so that they could be used either as cars or delivery vans.

Model 17

The passenger car was intended as a large, five-seater touring car for hotels and was offered as a 30 HP Model 17 . With a list price of 3500 US dollars , it belongs to the upper class of the time. Some engine data is available. Accordingly, this four-cylinder engine had a bore of 4.75 inches (120.65 mm) and a stroke of 4.25 inches (107.95 mm). A displacement of 301.6 ci corresponding to 4.9 liters is noted. A four-cylinder engine with a 4.75 inch cylinder bore receives an ALAM rating of 36.1 HP. Further motor data are not available; In particular, there is no information on valve control , carburetor , cooling and drive, i.e. gear , clutch and drive type ( cardan shaft or chain drive ).

The wheelbase of 109 inches (2769 mm) is consistent with the smallest truck. The fact that no special technical features are noted indicates that a conventional box frame was used as the chassis . Such a chassis differed practically only in the position of the engine in the frame. A suspension with semi-elliptic leaf springs and the use of rigid axles at the front and rear were common. No information can be given on the brakes used. The chassis, however, was designed as a right-hand drive, and wheels measuring 3 × 4 inches at the front and 35 × 5 inches at the rear were used. The vehicle weighed 4,000 lbs (about 1.8 tons).

commercial vehicles

The first Commerce -Truck was a cab-over with a payload of 2.5 sh. tn. (2.3 t) and also a four-cylinder engine with 30 bhp (22.4 kW) power. Chances are it was the same engine used in the Model 17 . This chassis also had a wheelbase of 109 inches (2769 mm). The company also retained the drive with double chains on the rear wheels used here for the larger trucks introduced in 1908. A model A with a 3 sh.tn (2.7 t) payload, 35 HP four-cylinder engine and 111 inch (2819 mm) wheelbase is known. Model C with 5 sh. tn. (4.5 t) payload and a wheelbase of 130 inches (3302 mm) had a total weight of 8400 lbs (3.8 t).

  1. ↑ The conversion of such probably rounded output values ​​can result in sham accuracy.
  2. ↑ The ALAM formula was usually used at this time . The Association of Licensed Automobile Manufacturers , an association of the automotive industry founded in 1900, introduced them in 1903. The power is not measured , but calculated: cylinder bore ² × number of cylinders; the result is divided by the constant 2.5. This method was also used by the RAC in the UK.
