PROCESS PATENTS. 



THE MILLER COED TIRE, 



OEVER.AL layers of rubber-impregnated cords are wound 

 '-' spirally around an annular core. The carcass is then slit 

 on the inner circumference and removed to a second core on 



which the tire is com- 

 pleted. The process con- 

 sists in first applying a 

 coating of cement to the 

 core upon which the 

 cords of the first-ply A 

 are wound at a definite 

 angle. They are spaced 

 apart at the tread por- 

 tion and nearly in contact along the inner circumference of the 

 core. 



A coating of rubber is then applied to the first ply and a 

 second cord ply B, is laid on the first at a reverse angle. This 

 procedure is repeated until a structure is built up having four 

 alternately superposed plies, A, B, C, D, of cords embedded 

 in rubber and arranged at reverse angles in respect to one an- 

 other. The carcass is then slit and placed on a core where the 

 tire is finished and subsequently placed in a mold and vulcanized 

 under pressure. [Walter R. Denman, assignor to Miller Rubber 

 Co.— both of .\kron, Ohio. United States patent No. 1,210,434.] 



Molding Fountain Pen Barrels. A tube of unvulcanized 

 rubber of the desired size and shape, containing a small quantity 

 of water, is closed at each end by plugs of raw rubber. The tube 

 is then inserted in a mold which is placed in a vulcanizer and the 

 tube vulcanized in the usual manner. The heat converts the 

 water within the tube into steam which forces the raw rubber 



against the mold, giving the desired shajie to the tube. [Herman 

 Rickman, Butler, New Jersey. United States patent No. 

 1.210,842.] 



THE ARCHER CORD TIRE, 



The straight side casing is made up of inner transverse cords 

 A, that fit within the intermediate longitudinal cords B, on which 

 are superposed transverse cords C. The ends of the inner 



cords arc- looped over cable strips 

 D. formed by strips of frictioned 

 fabric doubled ■ around annular 

 wire ,. cables. The longitudinal 

 cords B are interposed between 

 tlie inner and outer cord layers. 

 The outer transverse cords Care 

 looped over cable strips E. In 

 the clincher casing the inner cords 

 are bulged inwardly and looped 

 over an inner cable strip and 

 then passed over the ends of the 

 outer cords and looped over the outer cable strip. [Charles L. 

 Archer, Minneapolis, Minnesota. United States patent No 1 

 211,035.] ■ '

A FRENCH PNEUMATIC WHEEL. 



'N this wheel" the pneumatic arrange- 

 ment is placed :in. the hub. To the : 

 sleeve A, two annular disks B are at- 

 tached and casing C forms an outside 

 cover. To this are attached two disks 

 D com'pletely enclosiiig the hub. In 

 this space is arranged a pneumatic 

 cushion E, of suitable thickness (one 

 or two centimeters at the utmost) 

 and ,,of Variable diameter, enclosing an 

 air tube F. 



The spokes of the wheel are at- 

 tached to the periphery of the hub, 

 and 'the disks B and D may be four or 

 more • in number and attached alter- 

 nately to the hub A and the cover C. 



The pneumatic device is concen- 

 trically enclosed in the hub, and turns 

 with it and with the wheel.^ [J.'Grcppi and h. Romanach. French 

 patent Xo. 481,036.]
