Fig. 430. — Same type hopper and rotating arms as in 

 Fig. 429, but a different chute, designed to feed bolts. 

 Kicker wheel at the mouth of the chute kicks back into 

 the hopper the bolts that do not enter the chute properly.

Hopper sides ^ 



Fig. 431. — Hopper used for feeding 

 shell-like pieces into a tube conveyer. 

 A reciprocating plunger picks up the 

 work at the lower end of the stroke and 

 deposits it in snap fingers at the end of 

 the conveyer tube. 



Fig. 432. — The hopper is adjustable for feeding various lengths 

 and diameters of plain round stock, the pieces falling into the chute 

 by gravity. The agitator finger at either end of the work prevents 

 bridging or wedging of blanks over the chute opening.

FiG. 433. — An oscillating arm carries the blade through the center of the bolt hopper and at the top of its stroke 

 forms a continuation of the bolt chute. Sides of the hopper are inclined toward the center to feed bolts into the blade 

 at a low position in the hopper. One blade is used for each diameter of stock handled, tapered spacers in hopper being 

 adjustable to accommodate varying widths of blade.
