75 h.p. Fire-engine. Gully Emptier. Refuse collecting Wagon. 4-ton Van.
STAND No. 114.
THE outstanding machine on the Halley stand is the huge 75 bap. fireengine, which has a capacity of 500 to 600 galloes per minute. The engine of this pump has a bore of 5 ins. and a stroke of 61 ins., and it drives through a single-plate clutch to a four-speed-andreverse gearbox and thence to a wormdriven rear axle. There is an auxiliary gearbox between the clutch and the main gearbox, and this encloses the transmission from the clutch shaft to a double universally jointed propeller shaft by which the pump, located at the extreme rear of the chassis, is driven.
An auxiliary gear pump is employed for drawing the supply of water either from a tank or hydrant for first-aid purposes, .and to avoid danger of any failure dual ignition is employed. The pump and exhaust form a unit built throughout
of gunmetal, and water can be lifted from a depth of 28 ft. in under one second per foot. Actually there are three municipal appliances shown. The second is a 750-gallon vacuum-type
gully and cesspit emptier, so designed that it may also be used for road sprinkling. This outfit utilizes the 4-ton ch-a-..:is, one of the features of which is a foot-brake drum mounted on the worm tailshaft.
The third municipalvehicle is a refuse collecting and tipping wagon on the forward-dash4ype 2-214on 25 ,h.p. chassis. It has been possible in this case to provide a body 13 ft. by 7 ft., although the total length of the vehicle does not exceed 17 ft. The cab is carried at the side of the engine and it accommodates two persons, which is unusual for a vehicle of this type. The body is built with hinged covers, with stops to prevent these covers falling back too far. The last vehicle is l large van, built
for a firm of -wholesale grocers. This has a tail-hoard and rear curtains and is mounted on the standard 4-ton chassis.
