The Bourne VX was the larger of two American truck models produced by the Bourne Magnetic Truck Company in Philadelphia . It was introduced at the end of 1916 and remained in the program as long as the company existed. A special technical feature was its electromagnetic transmission system Entz .

Brand and company history

The company was founded in 1915 by Stephen N. Bourne founded after the oil company Atlantic Refining Company commercial vehicle prototypes had made. First the slightly smaller, technically very similar Bourne VM was produced and shortly afterwards the VX presented here . The Bourne Magnetic Truck Company moved to New York City in 1917 or 1918 . Production ended in 1918 or 1919, but the truck was advertised in October 1919. The reasons for the cessation of production are unknown.

Model history

The Bourne VM was the larger of the two commercial vehicle models from this manufacturer with a payload of 3½ sh tn (3175 kg). The company started production with the VM in late 1916 . The VX followed very soon. The use of the patented Entz drive required a license from the rights holder Rauch & Lang in Cleveland, Ohio . This also manufactured the upper-class car Owen Magnetic , which used the same drive principle. Both companies worked together on customer support.

technology

The Bourne Magnetic Truck Company manufactured their own chassis and used stand-alone solutions for the suspension. This means that their products are more likely not to be classified as assembled vehicles , i.e. vehicles that have been put together from components pre-produced for the free market.

Engine and drive

Both Bourne trucks have the same water-cooled four - cylinder engine from the Hercules Gas Engine Company , which the Bourne Magnetic Truck Company wrote in an advertisement that it had been specially developed for trucks. The cooler was supplied by the Rome-Turney Radiator Company from Rome (New York) . It was almost rectangular in shape, with a ribbed top and protruding from a barrel-shaped hood.

The Bourne VX so it was not hybrid vehicle . The drive energy was provided by a standard internal combustion engine . Its only adaptation to the Entz drive is to replace the flywheel with a generator and a magnet at the rear of the crankshaft . The Entz drive replaces conventional gearboxes and clutches as part of the drive train. He works steplessly. It transfers the power to the cardan shaft , which in the case of the Bourne transfers it to the wheels with a worm gear in the rear axle; this was the usual technique at the time.

For the Bourne Magnetic Truck Company , the advantages of the Entz gearbox were the continuously variable, low-noise power transmission, the easier vehicle operation, reduced operating costs, longer service life and the additional function of the generator as an electric starter. As for the Owen Magnetic , the powertrain components for the Bourne VM and VX were sourced from General Electric .

Chassis and suspension

Since nothing else is mentioned, conventional box frames with rigid axles can be assumed for the chassis . The Bourne Magnetic Truck Company made them themselves using chrome- vanadium steel that had only been developed a few years earlier. The leaf springs came from the specialist Mather Spring Company in Ohio ; Bourne had developed its own fastening without bolts for this purpose. The few known pictures of the vehicle (a VM and a Bourne of unknown type in our own advertising) show double wheels on the rear axle. The vehicles had left-hand drive , wooden artillery wheels , solid rubber tires and half-open cabs. H. a solid roof but no side walls.
