pair rotating slightly faster than the latter pair. A ball retained 

 between these disks will be rotated slowly about an axis which 

 passes through the axes of the two shafts, then winding the 

 elastic thread in different circles around the core. 



The ball is lield in position by rollers / and A', mounted on the 

 ends of two pivoted arms provided with spring tension. For re- 

 moving the ball, the upper bearing, being pivoted to the main 

 shaft, is raised jnd lowered by the handle provided for that pur- 

 pose. [Martin McDaid, Leith, Scotland, assignor by mesne as-

PKEPAHING AND APPLYING ADHESIVE COATINGS WITHOUT 

 SOLVENTS. 



A CCORDIXG to this invention the fabric used for making 

 ^^ "Gem" insoles is coated with adhesive without the use of 

 solvents. Gutta percha, pontianak, balata or other gums that be- 

 come plastic and adhesive when heated are mixed with wax on 

 the mill A, shown in the illustration. The dough is then trans- 

 ferred to the tank B, containing water heated to a temperature of 

 about 200 degrees F. From here the softened material is fed to 

 the mixing and straining machine C, where it is teinpered and

the coating to the fabric. The spreading knife is attached to a 

 hollow support heated by steam that maintains the coating mate- 

 rial in a plastic condition during the spreading operation. [James 

 Meade, Stoughton, Massachusetts. . United States patent No. 

 1,222.967.] 



METHOD OF MAKING TIRE FABRIC. 



I "IRE building fabric is made by braiding the fabric upon a 

 series of annular cores of the size and shape of the tire 

 casing. The bands thus formed are cut circumferentially and 

 used for building the casings of pneumatic tires. 



The illustration shows a series 

 of collapsible cores placed one 

 upon the other and around which 

 the fabric is formed by any pre- 

 ferred form of braiding mechan- 

 ism. The forms may be either 

 moved upward or downward dur- 

 ing the braiding operation. When 

 they are moved upward those on 

 w-hich the fabric has been braided 

 are removed from the top and 

 others added at the bottom, 

 thereby permittiBg a continuous 

 operation of the machine. Tlie 

 yarn may be impregnated with or 

 laid in rubber during the braid- 

 ing process. [George F. Fisher, 

 Plainfield, X'ew Jersey, assignor to The Hartford Rubber Works, 

 Hartford, Connecticut. United States patent No. 1,224,878.]

 thumb positioned opposite to the fingers and reinforced on the in- 

 side of the thumb, fingers and palm, is made in a mold from sheet 

 stock and press cured. [Richard T. Griffiths, assignor to The

MISCELLANEOUS PATENTS. 



A FRENCH CUSHION TIRE. 



IN this tire, the inner tube that is usually employed in ordinary 

 ■*■ pneumatic tires is replaced by a thick tube of flexible rubber, 

 the central opening of which is ovoid shaped. The walls are 



softened to the right consistency for sjireading. The strained ma- 

 terial is then directed to the spreading machine D, which applies 



tliinnest at the tread part and thicker at the base. A valve is 

 provided that permits the air to escape or enter the tire auto- 

 matically. 



The improvements are as follows and consist in corrugating 

 the walls of the tire, shown at A; in providing the exterior of 

 the tire W'ith fabric plies B to prevent wear when it is covered 

 with a casing, as shown at C, and in securing the tire to the rim 

 l>y bolts, D. 



This tire may also be used directly on the rim without a casing. 

 In this case it is provided with beads E that lit into corresponding 

 channels in the rim. The tire may be divided along its annular 

 circumference as at V , and provided with expansible sleeves G 

 and tapering bolts H , the action of which expands the beads 

 and holds the tire firmly in place on the rim. [A. Broussois.
