IMPROVED CLICKING MACHINES. 



FABRIC CUTTING I'RACTiCE in the rubber factories of this country 

 is showing a strong tendency toward the use of clicking 

 machines in place of the old-style beam dinker. Two types 

 are used — one for quantitative and qualitative cutting of all 

 fabrics, and the other on work of a lislitcr nature. 



In the use of the clicking machni 

 claimed over the old-fashioned mithod 



antages are 

 's the great 



operate, and it is more 

 that the percentage of

liability of injury; it is less laborious 

 economical in the use of materials, 

 scrap is reduced to the minimum. 



The cutting block of the ordinary dieing-out macliine is a 

 very inconvenient height and some of the dies are heavy and 

 hard to move. In the clicking machine the working surface is 

 at a restful height and in plain view ; the die is light in weight 

 :ind easily shifted and practically all danger of operating has been 

 1 liminated- With the fabric directly below his eyes on the 

 cutting board the workman can place his dies on the clicking 

 machine to cut more economically. 



One of the greatest advantages claimed for the clicking ma- 

 chine is the accuracy of its work. On the beam dinker a heavy 

 die is forced through many thicknesses of fabric, causing the 

 material to spread, thus producing inaccurate cutting. (United 

 Shoe Machinery Corporation, .Mbany Building, Boston. Massa-

A NEW ENCLOSED MIXING MACHINE. 



In the accompanying illustration is shown a mixing ma- 

 chine of the enclosed type, possessing structural features 

 that are designed to produce a maximum product in a 

 minimum of time. 



The frame of 

 this machine is of 

 substantial con- 

 struction and suf- 

 ficiently high so 

 that the clear- 

 ance of the mix- 

 ing tank from the 

 floor is at least 

 30 inches when 

 tilted. The mix- 

 ing tank is made 

 of close-grained 

 gray iron casting 

 and jacketed and 

 the inside is ma- 

 chined smooth. 

 The heads are 

 also made of 

 close - grained 

 gray iron cast- 

 ing, and are fitted 

 with special stuf- 

 fing boxes. The 

 agitator is of 

 special design, 

 capable of mixing the rubber 

 The agitator shafts are hollo 

 cooling fixtures. 



The dust-proof feed-hopper is clamped tightly on the 

 mixing trough when the machine is in operation. It con- 

 tains separate compartments for the various materials, which 

 are fed into the mixing trough by a compression feeding 

 device that forces the required amount into the mixing 

 trough. To increase efficiency, a dustproof compression 

 cover can be raised sufficiently high to allow the dumping 

 of the mixing tank for discharge. Means are provided for 

 tilting the mixing tank either by hand or power. 



This type of machine is only built in 75 gallons capacity, 

 weight 3,400 pounds. (The East Iron Machine Co., Lima, 

 Ohio.)
