A Cord Tire. Kndlcss loops of rubber-impregnated strands 

 are twisted, forming cords with loops at each end which are 

 laid over the core and held by the bead wires which pass through 

 the loops of the cords. [George F. Fisher, Plainfield, New 

 Jersey, assignor to Morgan & Wright, Detroit, Michigan; United 

 States patent No. 1.183.965.] 



Bead Wire Forming Machine. .-X luimbcr of wire strands 

 can be wound on a form wheel by setting a stop bracket at a 

 point indicated on the scale. When the indicated number of 

 revolutions has been wound on the form w^heel the machine 

 stops automatically. | F. C. Brucker, .\kron, Ohio, assignor to 

 Miller Rubber Co.. Akron, Ohio; L'nited States patent No. 

 1,184,619.] 



Caliper Gages for Rubberized Fabrics. Two ordinary gages 

 are mounted above a tension roller over which the rubberized 

 fabric passes, the thickness being continuously indicated by the 

 gages. [Thomas Midgley, Worthington. Ohio, assignor to Mor- 

 gan & Wright, Detroit, Michigan ; United States patent No. 

 1,184,002.] 



Tire Building Machine. A filiiralit> nf -tnck rolls for 

 frictioned fabric of different widtliv arr iiiiiiiitiil nn ;; reel. Tlie 

 fabric is fed to the core, by- feci 1 rollers that sin-toh the fabric. 

 The feed rollers are driven li\ a friction wheel that contacts 

 with the core and regulates the stretch nf the different fabric 

 plies as they are applied to tlic core. [William W. McMahan, 

 assignor to Morgan & Wright, both of Detroit, Michigan; United 

 States patent No. 1,183,996.] 



British Patents. 



SEIBEKLING'S FRICTION CALENDERS. 



This patent relates to continuously-working apparatus for coat- 

 ing both sides of the fabric with rubber and for applying a skim 

 coating to one of the sides. The fabric to be coated is placed in 

 two stacks A, B, with a 

 railway sewing-machine 

 C interposed for joining 

 the end of B to the be- 

 ginning of A. The fab- 

 ric D is drawn from the 

 top of B and passes 

 through a tensioning 

 device E over idler rolls 

 35, 36, 41 to a calender 

 F, where the under side receives a coating of rubber. The fabric 

 then passes through a tensioning device G to a second calender 

 H, which coats fhe upper surface, and thence to a tensioning de- 

 vice / having cooling rollers S3, 56. The fabric next passes to 

 a device / wherein the selvage edges are trimmed off and a third 

 calender K applies a skim coating to the upper surface of the 

 fabric, which finally is wound up by a device L. [F. A. Seiber- 

 ling, Akron, Ohio. British patent No. 1,289 (1915).] 



A NEW DIPPING MACHINE. 



The cylindrical casing A is shown in end elevation ; 

 tains a central shaft B having radial arms supporting 

 outer ends four carriers C for the dipping 

 forms D. The lower part of the casing 

 forms a chamber E located over a hydraulic 

 ram, upon which is wheeled a solution tank 

 F through the doors G. The forms are in- 

 troduced through a door //. 



The shaft being locked, with one set of 

 forms arranged vertically over the tank, 

 pressure is applied to the ram and the tank 

 is raised until the forms are immersed in 

 the solution, then a trip lever shuts off the 

 pressure and opens the exhaust which 

 lowers the tank. 



and con- 

 at their 



VV'hen this is clear of the forms, the shaft is unlocked and 

 turned by means of the hand wheel to bring down the next set 

 of forms, and the operation is repeated. The tank has hinged 

 lids that open and close as it is raised or lowered. The vapors 

 escape through the pipe / and a steam coil / is provided for 

 drying the dipped forms. [J. W. Reeves, 25 Great Poultney 

 street, London, England. British patent No. 1,344 (1915).] 



Driving Belt for Motor Cycles. Two ridges extend con- 

 tinuously around the outer surface of the belt. In another type 

 transver.se ridges forming troughs are used, the idea in both 

 instances being to carry off any water that would cause the 

 lielt to slip. [Dunlop Rubber Co., Limited, London; British 

 patent No-. 4,692 (1915).] 



Gas Heated Vllcani/inc Press. The platens are heated by 

 gas burners in combination with means for automatically main- 

 taining the platens at a predetermined temperature. [I. Hall, 

 Whitehouse street, .Aston, Birmingham, England : British patent 

 No. 1,063 (1915).]
