The Cow-Proof Locks 



If a stanchion is to be worth anything at all, its lock must be cow-proof. 



A stanchion that a cow can open is a source of danger and a constant 

 cause of trouble. 



Only a man who has had the experience knows how big a nuisance a 

 stanchion lock can be when it is not right; for it takes but a very little time for 

 a cow, loose in the barn, to do a lot of damage. 



The James Locks are guaranteed to be right in every way, cow-proof — 

 yet easily opened by an attendant even when wearing heavy mittens or gloves. 

 May be opened quickly from the front or from the rear of the stall. Simply 

 slamming the stanchion shut locks it securely. 



The "Door-knob" type of James Locks shown on the opposite page is 

 opened lust as you would turn the knob on a door. It opens easily even though 

 the cow throws her weight against the stanchion — yet no cow can open it. 



The James locks are safety locks from every standpoint. For economy 

 and efficiency they are in a class of their own and have had much to do with 

 the supremacy of the James Stanchions. 



Stall Frame 



The James Stall Frame is made of standard weight pipe, 1 Vg-inch outside 

 diameter for the uprights, thickness of wall .14-inch, subject to the usual 

 variation of 5 per cent under or over. The horizontal of the frame is of the 

 same material, I'/Z inches square, thickness of wall .125 inch, subject to varia- 

 tion named above. The square pipe prevents the alignment device from 

 twisting, even when the bolts on the fittings are not drawn tight. If a round 

 pipe were used for the horizontal, the alignment device would twist, dropping 

 the stanchion enough to cause the eye bolt to wear.
