New Fire Truck Jack
When a fire apparatus is in quarters with the full weight of the body resting upon the tires, there is a certain amount of strain resulting from this dead weight upon the fibres. Especially is this the case if there is an abraision anywhere in the material, and this is bound to lessen the life of the tires. A new Fire Truck Jack, put out by the Joyce-Cridland Company, of Dayton, Ohio, an illustration of which appears herewith, is designed to relieve this strain on the tires when the machine is not in use. It is of the telescopic type, with ratchet lever and rolling base. Its height, closed, is nine inches, with a rise of 12 inches, making a total height at full rise of 21 inches. This gives the jack a wide range in rise with low head room and the ratchet lever operating horizontally instead of vertically permits the jack to be used in close quarters under the truck. The base is formed of malleable iron and the screws are milled from cold rolled steel. One feature is the rolling base which enables the jack to release itself smoothly and without jar when the machine moves out.
