from the felloes scatters down onto these iron bands 

 and rolls. off to the ground. There is a hole through 

 each band on the outer ends of the hubs to pass the 

 linchpin through so that before taking off a wheel to 

 oil the journal it must first be turned so the hole comes 

 directly over the linchpin. To pry out the linchpin the 

 drawbolt is used. Old-fashioned drawbolts were made 



Figure 162. Wagon Brake. The hounds are tilted up to show the 

 brake beam and the manner of attaching it. The brake lever is 

 fastened to the forward side of the rear bolster and turns up along- 

 side of the bolster stake. The brake rod reaches from the upper end 

 of the lever elbow to the foot ratchet at the front end of the wagon 

 box.

with a chisel shaped end tapered from both sides to a 

 thickness of about an eighth of an inch. This thin 

 wedge end of the drawbolt is placed under the end of 

 the linchpin. The lower side of the hub-band forms a 

 fulcrum to pry the pin up through the hole in the up- 

 per side of the sand-band projection. The linchpin has 

 a hook on the outer side of the upper end so the lever 

 is transferred to the top of the sand-band when another 

 pry lifts the pin clear out of the hole in the end of the 

 axle so the wheel may be removed and grease applied
