different materials a device is provided that rings a bell when 

 the predetermined number of revolutions has been completed. 

 In commencing operations, the door being closed and the 

 weight raised, the material is placed in the machine, the weight 

 lowered and the rotors started. After a predetermined number 

 of revolutions, air or water is automatically admitted to the upper 

 cylinder, the weight is raised and dry ingredients are fed into 

 the machine. At the end of this period the weight is automatic- 

 ally lowered and bears on the material during the mixing opera- 

 tion. When this is completed the mechanism controlling the 

 door-locking device is operated, the door released and, swinging 

 downward, discharges the contents of the cyhnders. [Fernley H.

ANCHORAGE FOR CORDS OF COKD TIRES. 



This invention relates to the true cord tire in which the parallel 

 cords comprising the carcass are laid over the core at an angle 

 and anchored at the beads. In the illustration, A is the core 



with an internal rib to 

 each side of which two 

 angle-shaped rings B,B, 

 are bolted. Screws C,C, 

 serve to hold in place 

 the two segmented rings 

 D,D, that are provided 

 with cord locating pins 

 E, E. Two helical, end- 

 less wire coils F, F, having one-half the number of convolutions 

 as there are pins on each side of the core, are located just within 

 the pins by any temporary means. 



When the coils of wire have been fixed in position, one end 

 of the cord is anchored in any suitable way and the cord is first 

 doubled upon itself and the bight slipped over one of the con- 

 volutions of the wire. The cord is again looped or doubled upon 

 itself and the bight placed over a convolution of the opposite wire 

 coil. When the cord is pulled tightly about the core the bights 

 will be slightly separated and drawn upward on the inside of the 

 coils. 



When the inner layer of cords has been placed in position on 

 the core, the last run will come into position near the first end 

 which was temporarily anchored in position. The two ends may 

 then be tied together, or the same cord continued without cutting 

 so that the second layer of cords is formed in a manner similar 

 to the first except that the angle of the cords is opposite to that 

 of the first layer. [Benjamin L. Stowe, Jersey City. New Jersey, 

 assignor to Morgan & ^^'right, Detroit, Michigan, United States 

 Patent No. 1,228,144.] 



RUBBER FOOTWEAR ROLLING MACHINE. 



This macliine is primarily designed to apply air pressure to 

 rubber footwear while on the lasts and prior to vulcanization. 

 The illustration is a side elevation of the machine that com- 

 prises two tandem air 

 cylinders ^i and B, the 

 inner ends being open 

 and spaced apart, while 

 the outer ends are closed. 

 A head C connected to 

 pistons operating in hy- 

 draulic cylinders D and 

 E, reciprocates between 

 the open ends of the tan- 

 dem cylinders. A hol- 

 low bar or last carrier F, 

 provided with nipples for supporting the lasts, projects from the 

 outer face of tlie head. Two arms loosely mounted on the last 

 carrier, support on their outer ends a shaft G, on which are ar- 

 ranged a number of presser arms H, that press the lasts on the 



carrier bars, thereby insuring an air-tight joint. From the inner 

 face of the reciprocating head a last carrier identical to the one 

 just described projects in an opposite direction; however, this 

 is not shown in the illustration. The four-way hydraulic valve 

 controlling the reciprocal movement of the head and the three- 

 way valve controlling air pressure in the cylinders are operated 

 by a cam movement shown at /, that is, transmitted to the valve 

 stems by chain gearing. 



The shoes on the perforated lasts are placed on the carrier 

 bar, being held in place by the presser arms and the clutch 

 mechanism started that operates the hydraulic valve. The head 

 then moves to the right, entering the shoe carrier in the right 

 hand air cylinder and hermetically closing it at the same time. 

 .A.ir is then automatically admitted to the cylinder, thereby ap- 

 plying pressure to the shoes on the lasts. Entrapped air escapes 

 through the lasts and the hollow carrier bar to the atmosphere. 

 When the machine is reversed the air is automatically released 

 from the right cylinder and the hydraulic pistons move the head 

 to the left, entering the left shoe carrier in the corresponding 

 air cylinder when pressure is applied to the shoes. [Alfred A.

 Finch, Brighton, assignors to Hood Rubber Co., Watertown— all 

 in Massachusetts. United States patent No. 1,228.904.]
