The Abresch-Cramer Model C was an American truck manufactured in 1909 by the Charles Abresch Company and 1910-1912 by the Abresch-Cramer Auto Truck Company as the smallest of three series. The mark is occasionally referenced as Abresch and Abresch-Kremers .
Abresch-Cramer Auto Truck Company
The Abresch-Cramer Auto Truck Company was a corporation registered subsidiary of the Charles Abresch Company, founded in Milwaukee ( Wisconsin ) in 1871 , which had also manufactured the first copies of the Abresch-Cramer truck. Abresch was a nationally known manufacturer of carts for breweries and bottlers; Charles Abresch (1850–1912 ) immigrated from Dierdorf (today in the Neuwied district , Rhineland-Palatinate ) in 1868 .
The engineer Robert Cramer from Milwaukee, who studied in Europe and previously worked for Allis-Chalmers , was the designer of the commercial vehicles, which were built unchanged during their production time, and later the managing director of the Abresch-Cramer Auto Truck Company .
Model history
The Abresch-Cramer Car Truck Company was a corporation registered subsidiary of Charles Abresch Company in Milwaukee ( Wisconsin ), which was founded in 1871 for the production of wagons and had specialized in vehicles for breweries and bottlers. Charles Abresch (1850-1912) came from Dierdorf (today in the Neuwied district , Rhineland-Palatinate ). At the age of 18 he emigrated to the USA.
Truck production was initiated by Robert Kremers , an engineer from Milwaukee who also designed these vehicles. He had changed his name to Cramer .
technology
Model A was Abresch-Cramer's smallest truck. The three series offered were technically very similar. The differences lay in the wheelbase (and thus length), displacement and the resulting payload .
engine
Abresch-Cramer used four-cylinder four - stroke engines , the cylinders of which were typically cast in pairs of the time; Usually, the two blocks were with the crankcase screwed. He worked with T-head - valve control . In the absence of suitable seals, internal combustion engines were usually designed without a removable cylinder head . The crankshaft was forged and heat-treated, the nickel steel valves were interchangeable and mounted on Parson bearings with bronze bushings. Four piston rings were used per piston . The lubrication was carried out in a pressure circulation process with an oil pump . The water cooling was promoted by a water pump driven by a camshaft ; Due to their design, T-head engines have one camshaft each for the intake and exhaust valves . A speed limiter with centrifugal switch was part of the equipment. Abresch-Cramer were Rayfield - carburetors and American Bosch - magneto ignition delivered; At least for model B , double ignition and an ignition coil and an auxiliary battery with dry cells to support the ignition are proven. There is no related information on the Model A engine .
The Model A engine had a 3¾ inch (95.25 mm) bore and a 5 inch (127 mm) stroke , resulting in a displacement of 220.9 ci, respectively. 3620 cc. It should be noted that at that time rounded dimensions were usually given for bore and stroke so that these values are only approximate. According to the ALAM rating (ALAM: Association of Licensed Automobile Manufacturers ) based on the bore , this engine had a calculated output of 22.5 HP; Abresch-Cramer called 23 HP according to the "SAE formula". Obviously, this provided very similar data to the commonly used ALAM rating. The ALAM had already specified its information around 1903 and obliged its members to do so; the successor organization NACC ( National Automobile Chamber of Commerce ) confirmed it and expanded it around 1912. This method remained in use until the early 1920s. It is conceivable that the SAE (at that time: Society of Automobile Engineers ) calculated using the ALAM method around 1910.
The engine supplier cannot be found in the available sources; The market leaders Continental and Buda , both of which did not produce T-head engines , are excluded . Abresch-Cramer used ignition systems from American Bosch and carburetors from Rayfield or Stromberg .
drive
The power was transmitted via a three-speed gearbox with reverse gear and a multi-plate clutch in an oil bath, typically by means of a drive shaft and a countershaft in front of the rear axle. The gearbox, differential and countershaft were blocked. Chains on both sides of the countershaft led to the rear wheels.
chassis
A lead frame is not mentioned, but can be assumed. The wheelbase is only for Model C known. It was either 145 inches (3683 mm) or 175 inches (4445 mm). It can be assumed that Model A had a shorter and Model B had a wheelbase of no more than the same length.
The vehicle had rigid axles front and rear, semi-elliptic leaf springs all around, two brake systems (probably analogous to Model B, a pedal-operated brake drum on the countershaft and drum brakes that acted on the rear wheels with a handbrake lever ) and artillery wheels with solid rubber tires measuring 36 × 3 inches at the front and 36 × 3½ inches at the back.
Superstructures
Most of the superstructures of the Abresh-Cramer trucks were built in the nearby parent company, which had been set up for this purpose since the turn of the century and, in addition to its wagons - preferably for breweries - mainly clad trucks.
Remarks
- ↑ The Association of Licensed Automobile Manufacturers worked out the first US standard for engine performance, which provides reasonably accurate values for 1904–1911. The benefit is calculated; Cylinder bore ² × number of cylinders; the result is divided by 2.5.
