two standards in front which carry a wooden crossbar 

 over the front end of the truck. This crossbar is used 

 for a handle to push or pull the truck. The height of 

 the handle-bar from the floor is three feet. Rear wheels 

 are five inches in diameter and work 

 on a swivel so they turn in any direc-

 to fit a one-inch steel axle and have 

 wide boxings bolted to the main tim-

 the platform truck are under the 

 frame so they do not project out in 

 the way, which is a great advantage 

 when the truck is being used in a 

 crowded place.

 on the same principle that farmers employ extra help 

 at threshing time and do it all up at once. Of course,
