THE INDIA RUBBER WORLD 



[June 1, 1916. 



pedestal of the machine also acts as a reservoir for the water 

 which the pump forces to the l<nife and back again through the 

 splash pan into the pedestal. 



The machine is equipped with six knives and mandrels for 

 skiving all sizes of tubes up to and including SJ^ inch. It is also 

 furnished with drive with countershaft or direct connection to 

 any motor that the customer may desire. [Allen Machine Co., 

 Erie, Pennsylvania.] 



ROLLS FOR REMOVING WRINKLES FROM FABRICS. 



The twin screw rolls illustrated herewith are designed as 

 an attachment for calenders, spreaders, bias cutters, brush- 

 •ins, rolling and measuring machines, for the purpose of 

 removing wrinkles, puck- 

 ers and turned edges 

 from the goods. This 

 device is particularly 

 useful in connection with 

 a rolling machine for 

 taking out wrinkles from 

 the liners and wrappers 

 used in tire and footwear manufacture. 



The rolls are cut with right and left-hand threads running 

 from the center towards each end, and are mounted in 

 stands so that they may be turned in any desired position 

 and give as much contact of the cloth as desired on each 

 of the screw rolls. The screw rolls may be adjusted to act 

 on goods running horizontally, vertically, or at any angle. 

 One screw roll acts on one side of the goods and the other 

 screw roll on the opposite side to straighten out the 

 selvages, no matter whether they are inclined to turn over 

 toward the face or the back of the goods. Only one belt is 

 necessary for driving both rolls. The rolls are regularly 

 made of iron, though on special work where there is liability 

 of rust they may be made of brass or other material. [Curtis 

 & Marble Machine Co.. Worcester, Massachusetts.] 



MILLER'S BL4.S FABRIC CUTTER FOR REPAIRMEN, 



This is a very useful little machine for repair shops where a 

 considerable volume of work is done. It is operated by a hand 

 crank, or a power attachment can be applied if so desired. As 

 the fabric is taken from the roll, the liner is automatically wound 



up on a roller. The machine being set for the required Width, the 

 fabric is fed between the knives and by pressing dbwjt'the foot 

 lever a strip is accurately cut off on the bias. ■■•V' 



The machine is useful in the manufacture of tires, reliners, 

 flaps, boots and air-bags and will cut from 20 to 30 strips of 

 fabric per minute. [Charles E. Miller, Anderson, Indiana.] 



GAS BURNERS FOR VULCANIZING AND HEATING. 



The use of illuminating gas as a heating medium for hard 

 rubber vulcanizing presses is apparently being accepted as good 

 practice by manufacturers of certain kinds of hard rubber goods. 



and the 



adapted 



.\ type of burner that is specially designed for this purpose would 

 therefore be of interest to show the development of gas heat as 

 a vulcanizing agent. 

 'The burner shown in 

 the illustration is of tl 

 three-burner type, a 

 ranged to be inserted 

 the chambered press platen through holes drilled in the side for 

 that purpose. A flexible rubber hose that allows for the platen 

 movement connects the header with the gas and air pipes that 

 are fitted with lever valves by which the supply of gas and air 

 is regulated. The number of these burner units usually corre- 

 sponds to the number of platens in the press and the degrees of 

 heat required Snigle burners are furnished for direct mold 

 heating, m tact all ^i/es are made to suit the quality of gas used 

 vhich the burner is intended. 



The other illustration shows 

 a powerful burner specially de- 

 signed for industrial and labor- 

 atory purposes. This particular 

 type of burner is used for heating 

 metal furnaces such as are used 

 in melting type metal, for casting 

 soft metal molds. It is easily 

 IS an atmospheric burner if so de- 

 sired, or it can be arranged to work under 

 air and gas pressure. The burner is made 

 to deliver the required number of heat units 

 in accordance with the work to be performed, 

 and the correct adjustment for the varying 

 quality of gas is also insured. [Tirrill Gas 

 Machine Lighting Co., New York City.] 



THE ADVANCE WASHER CUTTER. 



A hand-operated machine that will accurately and quickly 

 cut washers from sheet rubber, leather or asbestos would 

 apparently till a long-felt want in the repair shop or garage. 

 A press of the descrip- 

 tion shown here is made 

 of cast iron and the 

 crankshaft and plunger 

 head are of cold rolled 

 steel. The dies are made 

 of tempered tool steel 

 and turned down at the 

 cutting end to a sharp 

 uniform edge. There are 

 23 dies in the combina- 

 tion, which will cut 529 

 ^^ay^l^==^^SS:.^< ^^ ^Hm different sizes of wash- 

 ^^^^^ ers ranging from ^ 



nich to 3'4 inch outside diameter and any size inside diam- 

 eter within this range. A maple wood cutting block also 

 constitutes a part of the outfit, [.-\dvance Felt Specialty & 

 Cutting Co., Chicago, Illinois.] 



VANADIUM STEEL RUBBER SHEARS. 



For heavy work in cutting rubber, special shears have been 

 designed, shaped to the hand of the operator, to allow continual 

 use without tiring the wrist. A special feature is the automatic 

 tension, which consists of a coiled spring made of piano wire, 

 sunk in a hollow thimble between the blades. It is entirely out 

 of sight, but with its upward tension it takes up the wear of the 

 screw, keeps the blades in perfect adjustment and doubles the 

 life of the shears. These shears are made of vanadium steel of 

 extra hard temper, specially adapted to the heavy work re- 

 quired of them. [Perfection Shear Co., North Woodbury, Con- 

 necticut.]
