 The lay extends across the frame in a diagonal direction parallel 

 to said harness, the shuttle being thrown back and forth across 

 the lay by the picker sticks /. 



Thi warp threads H carried on the yarn beam J pass over a 

 roller and &ence through the heddles of the harness frames and 

 the reed, the shuttle being driven back and forth on the forward 

 side hi' the reed in order to weave the fabric which passes over a 

 tension bar and is wound up on the cloth beam A.'. [A. 11. Hen-

TENNIS BALL INFLATOR AND SEALER. 



Xew tennis balls frequently lose their resiliency and become 

 unsalable, while those used in play finally become soft and 

 lacking in rebounding qualities. A device fur inflating and re- 

 storing tennis balls, and one 

 that can be easily carried 

 about, is shown in the illus- 

 tration. ./ is the case that 

 supports the air valve B, 

 which is connected with an 

 air pump (not shown) by a 

 rubber tube C. 



Assume the ball E to have 

 lost its resiliency and to be 

 "dead." The operator first 

 punctures the ball with the 

 needle D. He will then oper- 

 ate the pump, thereby inflat- 

 ing the ball, the operation be- 

 ing continued to whatever 

 extent the operator deems 

 best, and as determined by 

 pressure of the fingers and 

 thumb upon the ball. The 

 pumping operation is then 

 discontinued, whereupon the 

 check-valve will automatically 

 close and prevent the com- 

 pressed air from escaping 

 from the ball. The screw of 

 the cement tube F is then 

 operated, forcing the cement 

 G into the ball, which the 

 operator slowly rotates, 

 thereby equally distributing the cement about the puncture. The 

 needle may then be withdrawn, and the cement will flow over 

 and into the puncture, sealing it perfectly; for the rubber cement 

 will adhere strongly to the inner structure of the ball. The 

 dotted lines represent the caps or covers that are used when 

 carrying the device about. [A. A. Green, United States patent 

 Xo. 1,138.749.] 



one of the gears, the other driving gear will continue to turn 

 the shuttle. An intermediate gear F transmits motion from the 

 gear E, which is fixed to the driving shaft. 



The tire while being wrapped is supported in a horizontal plane 

 by live rollers — H, 1, J, and two others not shown. These 

 rollers are inclined and revolve in bearings supported by upper 



TIRE WRAPPING MACHINE. 



This invention of P. E. Welton is an improved machine adapted 

 to wrap paper, tape or other fabric spirally around an annulus. 

 Tt is designed to wrap strips of paper or cloth around pnuematic 

 tires and tire casings, irrespective of their size. 



Referring to the illustration, A is the base and B the annular 

 shuttle whose function is to wind the strip D around the tire C. 

 A portion of the shuttle is cut away, leaving an opening through 

 which the tire is placed in the machine. 



The removable flange of the shuttle B is formed with periph- 

 eral gear teeth. Two driving years, E and G, mounted on the 

 frame of the machine, engage with the shuttle gear, being placed 

 apart so that when the cutaway part of the gear is adjacent to 



and lower annular frames. A portion of these frames is cut 

 away, leaving a gap which is in the vertical plane in which the 

 shuttle turns. Rollers H, and the one opposite (not shown) 

 are the driving rollers, and they are preferably of cylindrical form. 

 In operating the machine, one side of the tire is passed through 

 the opening in the shuttle and its supporting guide member. 

 The tire will come to rest in a horizontal position in contact with 

 the inclined rollers. When the tire is so placed, it will surround 

 one side of the shuttle, and likewise one side of the tire will be 

 surrounded by the shuttle. The end of the paper or fabric strip 

 is then drawn from the roll and made fast to the tire and the 

 machine set in operation. As the shuttle turns it winds the 

 strip spirally upon the tire which is being slowly turned in a 

 horizontal plane. [P. E. Welton. United States patent No. 

 1.140.729.] 



A NEW TIRE CASING MACHINE. 



W. C. Stevens has invented a machine for making fabric founda- 

 tions for tire casings. Plies of frictioned fabric are wound under 

 uniform tension on a rotating mandrel, means being provided for 

 rolling down the sides of the shaped fabric layers without the 

 formation of creases. 



Referring to the VIlW' 70 



drawing, the fabric 

 is unwound from the 

 drum 171. the liner 

 being taken up on 

 roller 170. The strip 

 is then led under 

 the guide-roller 156 

 and around the ten- 

 sion-roller 155 ti i the 

 mandrel 28. This is 

 rotated and drives 

 the friction - roller 

 157 on the shaft 

 152 geared to the 



shaft 153, carrying the roller 155 which is arranged to exert a 

 dragging or tensioning action on the fabric. The frame 148, 

 carrying the tensioning devices, rocks on a shaft 147, under the 

 control of springs 151, bearing on horizontal arms 149 of the 

 frame. After each layer is applied, the core is rotated at a 

 greater speed and the devices for rolling down the sides of the 

 fabric are advanced towards the core. The rolling discs 132, 

 are advanced towards the core by the carriage 63, and are 

 forced against the sides of the casing by a weight
