hardened steel roller bearings. These bearings are of the finest steel, turned perfectly true. Fifteen 

 of them in each wheel revolve around a tempered steel axle. On each end of the axle (see Fig. 19, page 163) 

 there is a revolving washer which prevents the friction that would be produced if the ends of the rollers were 

 allowed to rub against the castings. This is one more important Louden improvement covered by our 

 patents. Our wire track carriers can be operated a greater distance with less exertion than any other 

 light carrier made. 



THE BOX. The box for both the Quick Out and Self-Acting Carrier is made 42 inches long. 

 It is 22 inches wide and I 5,' 2 inches deep. The ends, sides and bottom of the box are made of high-grade 

 galvanized iron, reinforced by strong angle iron at the upper edges. 



SPRING END STOP. An important improvement with our Wire Track Litter Carrier is the patent 

 Spring End Stop. (See Fig. 753, page 162.) This end stop not only prevents the wheels from jumping the 

 track no matter how hard the carrier may be running, but it also starts the carrier back on its return trip. 



THE TRIP. The trip for both the Quick Out and Self-Acting Litter Carrier is adjustable. The 

 trip can be placed on the track at any point, and can be moved from place to place on the track without 

 removing any bolts. In fact the position of the trip may be shifted from the ground with a fork or shovel 

 handle. 



The trip for the carriers is so arranged that when carriers reach the trip the latch on the end of the 

 box is released, allowing the box to turn over and empty its load. Another good feature of our tripping 

 device on the wire track carriers is the fact that when tripped they stay tripped. After striking the trip 

 on the track the carrier box will turn over and can not be latched in upright position until the latch is 

 properly set. The setting of the latch is done without an instant's delay when the carrier comes back 

 to the barn.
