OTHER DEVICES 



Im -• G for Insulated Wire. — In the covering of 



insulated wire the rubbei is sometimes applied in an 



irregular manner or il derably in thickness. It is 



difficult to detect these variations, which usualb idually, 



result i fore the i 



is discovered. The indicating gage will preveni such occurn 

 When wire thai varies in sizi letween the standard 



llcrs a sensiti es over a graduati '1 scale, al - 



trading the attention of the operator. [W. II. \l> I 

 United States patent, No. 1.133.300.] 



ibb's Braiding Machine.— His latest invention relates to ma- 

 chines for braiding tubular fabrics, and can be applied to any 

 ordinary braiding machine. There is a supplemental mechanism 

 or attachment whereby any desired number of warp yarn 

 introduced into the fabric I or this purpose there are as many 

 shuttles as there are yarns to be introduced lips, shuttles, 

 located under thi she ,1 of interbraiding yarns, are projected up- 

 ward through the shed bj shuttle-throwing devices of novel 

 construction. Each shuttle travels in a vertically extended 

 raceway made in two sections with a gap between for the pa- 

 sage of the shed of braiding yarns. Fur controlling the shed 

 it is confined between two rings located respectively above and 

 "math the -bed. the space between forming the gap in which 

 the braiding yarns travel. The approaching surfaces of these 

 i ings an preferably made sinuous, these edges drawing closer 

 together in the paths of the shuttles and diverging between such 

 paths. [H. Z. Cobb, United States patent, No. 1.133.364.] 



Doubling and Cementing Fabrics. — A machine has recently 

 been patented by which materials such as leather, imitation 

 leather, mohair and the like are cemented to a hacking of 

 cotton cloth. It has two rotary heated rolls and means for 

 guiding two sheets of fabric from opposite sides over and 

 between the rolls. A heated doctor applies the waterproof ce- 

 ment evenly to the surface of the covering fabric, which is then 

 united to the backing fabric by passing between the heated rolls.

RON Feed for Mixing Mills. — The object of this device is 

 to return the material between the mixing rolls so that the mix- 

 ing operation will be continuous. It also provides for throwing 

 the apron out of gear or removing it entirely from contact with 

 the front roll. The partially mixed rubber and compound 

 p. isms down between the mixing rolls and falls on the apron, 

 winch carries it around the first roll as far as the apron is in 

 tct with it. The compound adheres to the first roll, and -is 

 carried downward and between the two rolls, making a con- 

 tinuous operation. When the batching is complete the apron 

 is dropped down out of the way and the compounded stock re- 

 ed. [P. E. Welton, United States patent. No. 1,134,172.] 

 In a recent patent Welton covers several improved apron con- 

 trolling devices and assembles the entire mechanism in a p 

 ble pan. The advantage in this is that the pan can be quickly 

 adjusted under any machine, thereby converting it into a self- 

 feeding mill. [P. 1 ; . and H. A. Welton. United Stat 

 No. 1.134,173.] 



Cementing Machine. — In the manufacture oi I ts and - 



it is customary to skive the margin of certain parts of the upper 

 and to apply cement to the skived margin, which is then folded 

 The cement must be applied evenly and quickly, which is the ob 

 ject of this invention. There is the usual cement tank, valve and 

 cement-applying roller, driven by a belt, conveniently arrat 

 above the machine table. Below this table a presser roll pn 

 jects through an opening in line with the cement roller, which 

 can be adjusted to the angle of the skive and presses the skived 

 upper firmly against the cement applying roller. [John B. llad- 

 away. assignor to United Shoe Machinery Co., United States 

 patent. No. 1.134.262.]

Roll G .< Devici \ eo it English invention relates to 



that class of rubber machinery in whicl ling times 



heating— the roll is necessary. The interior of the roll is di- 

 vided longitudinally bj a number of ribs, and is bored for a 

 tightly lining tube. lb,- lattei forms long chambers of the 

 spaces between the ribs, ami is also the central supply tube for 

 the heating or cooling medium. The longitudinal chambers are 

 connected with openings al each end so that water or steam cir- 

 culates freely through tin- system. Thus the whole surface of 

 tin roll is cooled or heated a- desired, [J. II. Nuttall and D. 

 Bridge. British patent. Xo. 1,102.] 



In comparing the above invention with the various American 

 types, the similarity to Bragg's built-up toll and Brewster's and 

 Norris' cooling rolls is noted. The longitudinal and conm ti 

 chambers located near the roll surface and the central si 

 passage for the water oi steam circulation are used in the 

 Xorris roll Both Bragg and Brewster use a modified form of 

 iln same idea. 



ADAMS0N STRAINING AND hEFINING MACHINE. 

 I he new 8-inch reclaiming machine shown in the illustration i~ 

 designed tor large capacity and heavy duty. It is bolted to a con- 

 tinuous bed plate that supports at one end a motor and cut double 

 helical reducing gear. The body of the machine is chambered fot 



et and i- supported by heavy side frames 

 bolted to the base plate. Journaled to the frames is the main 

 driving shaft that drives the hollow steel stock worm through 

 powerful cut spur gearing. The steel strainer head has unusual 

 ana. and an end plate with an efficient arrangement for holding 

 the wire cloth. [The Adamson Machine Co.. Akro
