The Maibohm Model A was a sporty four-cylinder - cars of the American lower middle class . The manufacturer of the automobile, built between 1916 and 1918 for the 1917 and 1918 model years, was the Maibohm Motors Company .

Maibohm Motors Company

→ Main article : Maibohm Motors Company

Model A was when it was introduced late 1916 the only offer of the manufacturer of Racine ( Wisconsin ). In 1918 he was given the six-cylinder Maibohm Model B as a larger series. The production of the Model A ended in the same year without a direct successor. Maibohm Motors experienced a conflagration on New Year's Eve 1918 and produced the revised six-cylinder model B-6 in new facilities in Sandusky ( Ohio ) from 1919 . The company was taken over by its creditors in May 1922. These formed the Courier Motors Company a rescue company whose only product of the Courier Model D was. Courier Motors went bankrupt in 1923 and had to close.

market

With prices between US $ 595 and 1095, the Maibohm Model A was conceived in a market segment that was dominated by the Ford Model T and in which many other manufacturers were fighting for survival. This price category included models from volume manufacturers such as Chevrolet , Dodge , Auburn , Hupmobile , Metz , Nash , Jordan , Oldsmobile , Reo , Saxon , Studebaker and Willys-Overland . There were numerous competitors of a size similar to Maibohm , including Allen Motor Corporation , Alter Motor Car Company , Commonwealth Motors Corporation , Dixie Motor Car Company with the Dixie Flyer , Hackett Motor Car Company, and Inter-State Automobile Company with their Model T , to name a few.

With a lighter constructed and cheaper sports car, the Grant Motor Car Company had already pursued a similar concept to Maibohm in 1913 , but abandoned this again around the time the Model A was introduced in favor of larger models. Also Scripps-Booth and Dile Motor Car Company were active in this segment, but failed with her after Cyclecar lightly built Criteria, but larger-sized sports cars. All these smaller manufacturers without a US-wide dealer network were of necessity regionally oriented. In addition to the listed sales prices, there were sometimes very high transport costs, which in the lower market segment could quickly exceed half the purchase price, as well as a long distance to the authorized workshop. Both were severe handicaps that forced quite a few providers to give up when the post-war recession hit the USA.

Maibohm was largely able to keep sales prices stable; only the roadster experienced a strong markup for 1918.

Competitor (selection)

The following list shows some comparable models from other manufacturers. A selection had to be made among the dozen brands.

Ford, Chevrolet, Dodge and Overland were among the market leaders at the time, Hupmobile, Jeffery / Nash and Metz were medium-sized and well-known suppliers, while Inter-State is an example of a similarly small automobile manufacturer.

technology

engine

The water-cooled four - cylinder engine is designed as an L-head , i.e. with "upright" valves. The bore, which is important for taxation, is 3⅛ inches , the piston stroke 4 inches. The displacement is given as 122.7 ci (2011 cm³). The crankshaft has two bearings. The power is 17 bhp (12.7 kW). The NACC rating is 15.63 HP. The engine is lubricated as centrifugal lubrication with an oil pump . A simple ignition system with a battery and cooling as a thermosiphon system that works without pressure are typical of the time and class. For the carburetion was a Zenith - carburetor used that may have been obtained in the US by a licensee.

Power transmission

The power is transmitted via a dry disc clutch to a three-speed gearbox. First, a rear axle was bevel gear - differential and a ratio of 4.0: 1. In 1918 the system was converted to a spiral bevel gear and a rear axle ratio of 4.25: 1.

Chassis and suspension

There is little information about the chassis. Typical time an execution than was pressed steel - leadframe with two offset side members and several (usually four or five) traverses. Torsion tubes (round bars as struts at the front and rear end of the chassis) did not exist according to the illustrations. The rigid axles front and rear are also typical of the time . The rear axle was "three-quarters floating" in model year 1917 and "floating" in 1918. Semi-elliptic leaf springs on the rear axle are also used . There is no information on the suspension of the front axle. Model B / B-6 had the usual front semi-elliptic leaf springs and it is very likely that this is already in the Model A were used. There is no information about the brakes. However, it can be assumed that both the service and auxiliary brakes acted on the brake drums on the rear axle, as in the Model B-6 . Front-wheel brakes did not gain acceptance on a broad front until after 1925.

The Maibohm Model A received wooden spoke artillery wheels with 30 × 3½ inch tires and, as far as can be seen in the illustrations, a removable wheel rim .

The wheelbase is 105 inches (2667 mm)

Like Ford, Maibohm also did without chassis numbers ; the engine number was used for this at the same time. For Model A , this was a maximum three-digit number with a value between 1 and 500. The sticker is attached to the left side of the engine block.

Body and model overview

The origin of the bodies is not documented, but the assumption that Maibohm, as a former coach builder, was set up for this is not far-fetched. The usual procedure was to plank a structure made of stored hardwood with sheet steel panels. As mentioned, there were only two-seater versions. The following were listed:

production

→ Main article : "Production figures" in the Maibohm Motors Company article

The production figures can be found in the Standard Catalog of American Cars 1805-1942 . According to this source, 828 vehicles were built in model year 1917 (including vehicles completed at the end of 1916) and 615 vehicles in 1918 (including model B ). The production figures for Model A can therefore not be determined exactly; but the number is consequently higher than 828 and lower than 1443. However, this finding collides with the chassis resp. Engine numbers reserved for this model only from 1 to 500.

Remarks

1. ↑ The Rex top from Rex Manufacturing Co. in Connersville (Indiana) was removable like a hard top and could be used with or without side panels. See also White's Permanent Top .
2. ↑ Predecessor formula for SAE-PS . NACC ( National Automobile Chamber of Commerce ) was an association of the automobile industry founded in 1913 and the successor to the ALAM ( Association of Licensed Automobile Manufacturers ), which introduced the first standards in US automobile manufacture in 1903. The inaccurate method for measuring performance was also used by the RAC in Great Britain and was mainly used for allocation to a tax class ( RAC Horsepower ).
3. ↑ "Free floating" designed axles have a wheel hub that is connected to the outer end of the axle body via a roller bearing . The half-waves are therefore freed from transverse forces. The outer shaft end is in the wheel hub, the torque is usually transmitted by means of a gear coupling .
4. ↑ To make work easier after a flat tire, only the removable wheel rim and tires were replaced, the hub and wooden spokes remained on the vehicle. Such demountable rims were common in the 1910s and 1920s.
5. ↑ You probably mean a removable winter top similar to a hard top . These could be used with or without side panels. See also White's Permanent Top .
6. ↑ You probably mean a removable winter top similar to a hard top . These could be used with or without side panels. See also White's Permanent Top .
