TIRE-CASING TOOL.
Specification of Letters Patent.
Patented Nov. 10, 1914.
Application filed March 13, 1913. Serial No. 753,981.
To all who) it may concern:
Be it known that I, Axm. A. NELSON, of 'ashington, in the District of Columbia, have invented certain new and useful Improvements in. Tire-Casing Tools; and I do hereby declare the fi'illowing to be a full, clear. and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
in Letters Patent No. 1,041,660. issued to me on the 15th day of October, 1912 I showed and described a tool for removing automobile tire casings, which tool has a wheel-spoke, and a strut also designed to bear against the wheel-spoke to hold the tool in different positions into which it may be moved. whereby after the tool has been once properly positioned it need not be held by the operator. leaving him free to use bot-h hands in the prosecution of his work. The tool referred to was specially designed for removing casings directly from the wheels of automobiles. it was not applicable, however, to removing casings from what are known as demountable rims. from which the casings are removed when the rims themselves are not secured to the wheels.
The object of my present invention is to provide a simple and highly efiicient tool for removing casings from demountable rims, such tool being capable of remaining in the positions to which adjusted by the operator.
in the accompanying drawings Figure l is a side elevation of the tool. as used for releasing a locking ring. Fig. 2 is a sectional detail. Fig. 3 shows the tool as used for forcing the casing from the rim.
Referring to the drawings, 1' designates a demountable rim of known construction and capable of being readily secured to and removed from an automobile wheel.
As is well known. a tire casing is held in place on a demountable rim between an inner curved flange 2 and outer ring 3, the latter being secured by a locking ring 1, which fits in a groove extending circumferentially of the rim, the flange 2 and the ring 3 engaging and holding the beads of the casing. The flange 2 is integral with the rim. To insert or remove the locking ring ring 3 in the manner represented in Fig. 1. For this purpose I employ a lever 5 having a fulcrum bearing in the form of a hooked arm 6, the hooked end of which conforms to the curved flange 2 of the rim. This hooked arm is adjustably and detachably connected to the lever by a pivot in T to accommodate rims of diflerent Width. This lever carries at its end a detachable and reversible arm 8, which at one end, 9, is formed to fit ring 3, and at its other end, 10, is curved to conform to the side of a casing at a point adjacent its bead, as shown in Fig. By pulling outwardly on the free end of the lever the arm 8 thereof by engaging at its end 9 the ring 3 can force such ring away from the lock ring, as shown in Fig. 1.
strut 12 is detachably connected to arm 6 at a point. beneath the hooked end thereof, and at its other end this strut engages a rack 13 of lever 1. The strut may engage the rack either at its extreme end or at an offset 1.4, the latter being employed preferably when the pivot pin is inserted through the innermost hole of the hooked arm. When the pin is inserted through the outer hole the extreme end of the strut may be caused to engage the rack. The strut is detachably connected to the hooked arm preferably by means of a cross pin 15 entering a curved slot 16. When the strut is practically inverted the pin 15 may be withdrawn from or inserted into slot 16. In all other positions the pin and slot connection precludes the separation of the strut from the hooked arm. When the. necessary pressure has been applied to the lever to force the outer ring 3 inwardly to free the locking ring, the parts will be retained by the strut in the position to which they are moved, thereby leaving the operator free to manipulate the lock ring.
When it is desired to utilize the tool for forcing a casing from the rim, after the lock ring 41 and the inner ring 3 have been removed, arm 8 is reversed and inverted, and arm 6 is inverted, as shown in Fig. 3, so that a second hook 17 at the free end of said arm will engage the outer flanged edge of the rim and enable pressure to be applied through arm 8 to the inner portion of the casing. hen the tool is thus used the strut is not required.
From what has been said it will be seen that I have provided an extremely-simple and inexpensive tool for removing or positioning a tire casing on an automobile rim,
which tool when once applied will remain in the position to which adjusted.
I claim as my invention: A tire-casing tool comprising a lever hav- 5 ing a reversible overhanging arm extending in opposite directions therefrom, the ends of said arm being arranged to conform toopposite points of a tire casing, a reversible fulcrum bearing having two hooks at its 10 free end for engaging opposite sides of a wheel rim, and means detachably connecting said fulcrum bearing to said lever to permit it to be inverted when said arm is reversed. In testimony whereof, I have signed this specification in the presence of two subscrib- I71 ing Witnesses.
