TOOL FOR -REMOVING ANO REPLACING COVERS OF PNEUMATIC TIRES.
SPECIFICATION forming part of Letters Patent No. 620,837, dated March 7, 1899.
Application filed December 24, 1898. Serial No. 700,191. (No model.)
To @ZZ whom t may concern.-
Beit known that LTHOMAS BENNETT, a subject of the Queen of Great Britain, residing at London, England, have invented a newV and useful Improved Tool for Removing and Replacing the Covers of Pneumatic Tires, (for which patents have been applied for in Great Britain,No. 17,370, dated August 11, 1898; in Germany, No. 23,275, dated August 25, 1898; in Austria, dated October 17, 1898; in France, No. 270,099,dated October 18, 1898; in Belgium, No. 108,418, dated October 19, 1898; in Switzerland, No. 19,550, dated October 20, 1898; in Denmark, No. 1,120, dated October 22, 1898,v and in Hungary, No. 15,125, dated October 24, 1898,) of which the following is a specification.
This invention relates to an improved tool for removing the outer covers of pneumatic tires of the kind provided with endless wires from the rims of wheels and also for replacing them thereon with greater facility than has heretofore been possible.
According to the invention I provide a tool consisting in the combination, with a lever or its equivalent adapted to be inserted under the edge of the tire-cover for raising it, of what may be termed an advancing arm or horn, the parts being so arranged that when the tire-cover has been raised the arm springs or can be pushed forward, and being thicker than ,the lever will be gripped between the edge of the cover and the rim, so as to allow the lever to be advanced up to the arm, and so on, until the tire-cover has been sufficiently removed, as hereinafter more particularly described. 4
To raise the tire-cover sufficiently to enable the spring or other arm or horn to spring orv be pushed forward, various devices or constructions of tool can be employed, and to enable the invention to be clearly understood I will describe one form of tool by reference to the accompanying drawings, in which- Figure 1 is a side elevation of the tool. Fig. 2 is an elevation at right angles to that shown in Fig. 1. Fig. 3 is a plan. tion on the line 4 4, Fig. 1; and Figs. 5, 6, and
7 are views illustrating the method of employing the tool for removing the tire-cover.
In the tool shown the lever or its equiva- Fig. 4 is a seclent is made of a pair of arms a b, hinged t0- gether by the pin c and each formed at one end as a curved handle a' or b and iattened at its other end, as shown at a2 b2, the eXtreme' rim and the outer cover, as illustrated in v e represents the arm or horn,which is adapted to the lever a l). The said arm or horn is advantageously formed of wire, and when required to act springwise it is fitted to one yof the parts a b bybeing coiled around the pin f, which is riveted or otherwise suitably held between two lugs g g, formed upon or secured to one of the hinged arms, (in the drawings the arm b.) The said wire is then turned outward and upward, as shown at e', and formed into a loop e2, the free end being then turned inward, as shown at e3, passed through notches ab, formed in the two parts ab, and bent around at the end, so as to limit the`out= ward movement of the loop e2. The said loop e2 is thicker than the iiattened end of, the lever formed by the ends a2 b2 of the arms a b.
To make use of the improved tool for removing the outer cover of a deflated tire, the flattened end of the tool and the loop e2 of the spring-arm e are brought together and inserted .between the edge of the outer cover h of the tire and the wheel-rim i. The edge of the cover is then prized over the edge of the wheel-rim t' by moving the tool-handle downward, as shown in Fig. 5, the end of the spring-arm e `and the edge of the flat end of the tool being still in contact, as shown by the dotted lines inFig. 7. As the loop e2 is thicker than the end of the lever, it takes all the pressure of the outer cover, leaving the lever end free to move. By now gripping the handle portions a' b of the parts a b the flattened ends a2 b2 are separated from one another, as indicated in Fig. 6, so that the loop end e2 of the spring-arm e is released from the pressure of the cover and will spring forward into the position shown in full lines in Fig. 7, the amount of this forward movement being, as already mentioned, limited by the hooked end of the said wii'earm e. The flattened ends of the tool are now allowed to again come in contact by releasing the pressure upon the handles d b', and the lever portion of the tool is then advanced toward the spring arm or horn e and the operation repeated until the outer cover is suiciently removed from the rim.
The hooked end e3 of the spring-arm can be dispensed with, if desired, and instead of the spring-arm I can employ a pivoted arm adapted to be moved and not to spring forward.
Itwill be obvious thatvarious other means can be employed in lieu of the hingedparts a I) to effect the desired result-that is to say, to alternately make the end of thelever thicker and thinner than the spring arm or horn e, so that the said lever and the said springarm alternately take the pressure of the outer cover upon the rim and so that the springarm can be alternately released to spring forward and be gripped by the tire to allow the lever part ot' the tool to be advanced toward it in the manner above described.
To replace the cover h upon the rim e', itis put in the rim as far as it will go easily. The end of the tool is then inserted between the edge of the cover and the inside edge of the rim where the cover is already on the rim and as near as it will go to the part which has still to be put on, and the tool is worked, as above described. In this case of course the tool-handle points away from the Wheelhub instead of toward it, as when removing `the outer cover. i
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is` 1. A tool for removing and replacing pneumatic tires comprising among its members, a lever and a spring-actuated auxiliary arm or horn connected to said lever and having its outer end movable toward and from the said lever, substantially as described.
2. A tool for removing` and replacing the covers of pneumatic tires comprising among its members a lever, and a spring-actuated auxiliary arm or horn pivotally connected to said lever and having its outer end movable toward and from said lever, substantially as described.
3. A tool for removing and replacing the covers of pneumatic tires comprising among its members a lever having a llattened outer end, a spreading device secured thereto and
