A SUCCESSFUL SHOE VARNISHER. 



A N ingenious resident of Bristol, Rhode Island, IMr. J. II. 

 Wall, has evolved and patented a very simple and prac- 

 tical machine for varnishing rubber shoes, three illustrations 

 of which are shown herewith. The machine, which is protected 

 in the United States and abroad, has already been adopted on a 

 royalty basis by many large manufacturers — notably the North 

 British Rubber Co., of Edinburgh, Scotland ; the Beacon Falls 

 Rubber Shoe Co., the Apsley Rubber Co., the Hood Rubber Co., 

 and several of the Canadian shoe concerns. 



The maximum capacity of the varnisher is 1200 pairs in an 

 hour, with two men to feed it. As a rule, however, it is op- 

 crated by one man, the product being 500 pairs an hour. In one

[Machine just booking on to lower row.] 



of the factories where it has been installed a force of 52 men 

 was cut down to 18. 



As may be seen from the illustrations, a stick of shoes is 

 placed in the machines, a lever pulled, and the shoes descend into 

 the varnish, return, and are automatically caught up into the 

 upper rack, where they drain while the machine tender places 

 another stickful in position for dipping. 



Mr. Wall's United States patents are No. 817,408, April 10, 

 igo6; No. 841.3?!. January 15, T907: and Xo. 862,526, August 6,
