(patents pending) to demonstrate an important feature on all 

 large mills built by this company. The calender was equipped 

 with 3 chilled iron rolls, ground and polished, with a two-speed 

 control on the line shaft, and both friction and even connecting 

 gears of cut steel, the latter being controlled by jaw clutches, 

 which is a new feature. Further features on the calender were 

 the disc friction let-off and wind-up, the latter being driven by 

 small Diamond chain from the center roll. 



The journal bearings throughout were all brass, and oiled by 

 means of glass oilers. All line shaft bearings were ring oiling. 

 -All gearing was effectually protected by cast iron guards. The 

 features which received much favorable comment — features found 

 on "Vaughn" machinery only — were the method of changing con- 

 necting gears and the two speeds on the calender, the quick re- 

 movable adjusting screw and nut on the mill, and the patented 

 multiple band clutch on the line shaft. 



The exhibit was in charge of Mr. Lee Vaughn, secretary of 



Buffalo Foundry and Machine Co. 



llio company, who was assisted by Messrs. M. A. Pearson and 

 I H Ridgevvay, the New York representative. 



THE BUFFALO V.\CUUM DRYERS. 

 The e.xhibit of the Buffalo Foundry and Machine Co., though 



it was as far from the front entrance of the building as it could 

 get, being against the Western wall — was still exceedingly con- 

 spicuous, because it faced the Grand Central aisle, and every 

 visitor who mounted the marble stairway, on reaching its top 

 was bound to sec the illuminated sign and the large illuminated 

 picture of the Buffalo factory at the head of the aisle, although 

 they were all of 200 feet away. This exhibit was characterized by 

 a great deal of illumination — a series of illuminated pictures of 

 its various machines and machine parts forming a continuous 

 railing around the booth. 



Rut while the casual visitor was interested in these illuminated 

 effects, the rubber manufacturer was most attracted to the work- 

 ing exhibits inside the booth — one of which was a large vacuum 

 dryer with a capacity of 2^j tons of sheet rubber every twenty- 

 four hours. These dryers are made of one piece, thus elimi- 

 nating joipts and the consequent leakage. They are also made

of very dense metal, preventing the seepage of air. The dryer 

 is full of heating shelves, constructed either for steam or hot 

 water circulation. One or two particular features may be men- 

 tioned regarding these dryers: First, that the steam manifolds 

 are made of steel instead of cast iron, thus avoiding breakage; 

 and secondly, that the shelves are connected to these steam 

 manifolds by ground joints and in such a manner that no pack- 

 ing is used. 



One interesting feature of the e.xhibit was a small laboratory 

 vacuum shelf dryer where the centre of the stand formed the 

 condenser — and the base a receiving chamber for condensed 

 va|)ors. The vacuum in these dryers, by the way, comes within 

 1/10 inch of a perfect vacuum. The large dryer on exhibition 

 was built for the Independent Tire Co., of Toronto, while the 

 vacuum pump on exhibition was built for the General Electric 

 Co. Mr. E. G. Ivippel, sales manager, was in charge of the 

 exhibit.
