New and Bigger Jobs for the Sturdy Truck 



A fifteen-ton steam-hammer moved a 

 quarter mile on rollers by an automo- 

 bile chassis. So heavy was the piece 

 of machinery that steel rollers placed 

 under it were crushed like egg shells 



At left: A new jack to lift the wheels off 

 the floor when the car is in the garage. 

 The lip of the jack is placed under the 

 hub and the lift is accomplished by a 

 single upward motion of the hand 



At right: Preventing back draughts of dust 

 with an air scoop. The wind pressure enters 

 the scoop, placed at the front of the side- 

 car, and is forced out at the rear, break- 

 ing up the air eddies that carry the dust 



A radiator shutter, operated 

 from the driver's seat, keeps 

 the water from freezing 



An electric street-sprinkler with sprinklers in front, 

 giving the driver better control. The three-ton 

 truck carries an eight hundred-gallon water tank
