Robinson Motor Pumping Engines.
The city of Ventnor, N. J., recently awarded a contract to the Robinson Fire Apparatus Manufacturing Company for one of its pumping engines to cost $9,050. The motive power of the apparatus is a six cylinder gasoline engine of 110 horse power. The cylinders are cast in pairs, 6 1-4 inche bore and 6 3-4 inch stroke. This motor is almost twice the weight of an ordinary automobile motor of equal horse-power, owing to the increased size of the crank shaft, cam shaft, timing gears and all other working parts. There are two separate and complete systems of ignition, the lubrica tiou being mechanical 19 points. The clyinders are cooled with water and can be kept at any desired temperature. The fuel capacity is thirty gallons. There are double chain drivers on the rear wheels, here are 540 inches of breaking surface, the thread being sixty inches and the wheel base 155 inches. The wheels have solid rubber tires 38×6 inches. The speed of the apparatus is thirty miles an hour. The hose body will carry 1,000 feet of 3 1-2 inch hose. The axles are ball-bearing of special construction, solid front and rear. The frame is of Channel steel lined with hickory and thoroughly trussed. The chemical equipment consists of one thirty-five gallon tank and two hundred feet of chemical hose and all other accessories. The Robinson Fire Pump is for the triplex piston type capable of delivering 750 gallons of water per minute. The pump is said to be by technical engineers perfect in design, construction and action. There is no vibration in this machine when the pump is running at full capacity. The lighting system is electrical throughout The illustration shows a pumping engine of the same type in service at Elyria, Ohio. During its test it showed up better than the conditions specified in the contract, pumping over fifty gallons a minute more than the guarantee. It also more than equaled the speed limit and endurance tests and received the strong endorsement of the testing engineer and city officials.
