PATRIGKCANNON, OF NEW YORK, N. Y.

RIMrHOLDING- STAND.

Application filed May 16, 1919.

To all whom it may concern:

Be it known that I, PATRIOlLCANNON, a citizen of the United 'States, and a resident of the city 01? New York, borough of Manhattan, in the county of New Yorl; and State of New York, have inventeda new and Improved Rimsl-lolding Stand, or which the following is a full, clear, and exact description.

This invention relates to ameansfor facilitating the removal of a shoe or tirefrom a rim and more specifically to a device particularly adapted to be used-with a rim of what is commonly known as the detachable, demountable type.

The object of the invention is to provide a new and improved rim holding stand arranged to support a rim a short distance above a floor or ground to facilitate the removal of the shoe from the rim.

Another object is to provide a rim holding stand which is simple and durable in construction, readily adjustable to aocommodate different sized rims, and when not in use can be folded to take up very little, room for storing or shippingpurposes.

llith these and other objects in view, the invention consists or" certain novelteatures of construction asherei-nafter shown and described and then specifically pointed out in the claim, in which Figure 1 is a plan view showing the application ofthe device to a rim and shoe.

Fig. 2 is a side view of the device showing the tire and rim in section.

Fig. 3 is a view showing the device in its folded position.

Fig. at is a view showing the character of the openings in the ends of the arm members of the device for permitting adjustment thereof.

Fig. 5 is a view or" a bolt used for positioning the tire rim.

In the drawings showing one of the preferred forms of the invention it is there shown as comprising a plurality of L-shaped arm members 1, 2, 3, at. The members may be made of any suitable material, but bars of steel or iron may be suitably formed to serve the purpose in a most economical manner. As a means of conveniently positioning the arms when in a functioning position, as shown in Figs. 1 and 2, and also for positioning the arms when the device is in a folded position, as shown in Fig. 3, a suitable bolt ,Specifieation of Letters Patent.

Patented Apr. 20, 1920.

Serial No. 297,491.

5 passes through openings in one end of each of the arms, there being provided for the bolt athumb nut 6 or other suitable means for holding the arms in the two positions. Y

The bolt 5 is provided with a square shop...- der 8 engaging one of a series of square holes 7 formed in the arm 1 to hold the bolt and arm 1 in a fixed position and the number of openings servin as one means of ermitting a ready adjustment of the arms of the device to different sized rims.

The arm 2 positioned above the arm 1 on the bolt 5 is preferably provided with openings 9 to permit the bolt 5 to pass therethrough so that the arm may be moved freely about said bolt and it also is pro ulod with a number of openings to permit of adjustment. When in an operative position, the arm 2 will be moved about the bolt 5 so that it will extend on the opposite side or" the bolt to that ol the arm 1 so that it sub stantially forms a continuation of the arm 1. The other arm members 3, d are provided with slots 10, 11 in the ends thereof through which extends the bolt 5, these slotted portions also serving to permit of adjustment of these arms to-riins 01": different sizes. The arms 3, at, when in an operable position, will extend in opposite directions from the bolt 5 and will be angularly displayed from the arms .1, 2 by about ninety degrees.

It is to be understood, however, that I do not wish to be limited to the particular number of arms which are employed, the shape and form thereof or the character of the openings therein and positioning means therefor.

It is understood in the above statements that in rims of the solid detachable, demountable type, the device or means 18 normally tending to hold the shoe in position on the rim will first have to be removed before applying a force to the shoe 13 leaving one side of the rim 15 open so that the beads 16, 17 of the shoe may slide thereover. Rims of the above type are usually provided with a shoulder 19 on the inner surface of the rim extending therearound.

As a means of supporting the rim upon the arms spaced from the ground, there is preferably provided bolts 20 carried in threaded openings 21, 22, 2% located in the bent portion 25, 2G, 27, 28 of the arms, said bolts extending radially through the openings so that the ends may contact with the rim and serve as a seat for the shoul der' 19.

By the arrangement described the rim and the shoe 13 are supported a short distance above the ground to permit the operator to readily force the shoe downward and off the supported rim. Each of the bolts 20 has an outer, non-threaded. end 29 engaging the shoulder 19, thus preventing the latter from coming in contact with and injuring the thread of the bolt.

The openings in the ends of the arms are so positioned and the lengths of the respective arms are such that the device may be folded to occupy but little space by swing, ing or turning the arms about the bolt so that the arms will be in alinement, at which time the thumb nut 6 may be tightened holding one end of the arms in position. It is to be noted that the relatively fixed relation between the openings in the end of the arms 1, 2, through which the bolt 5 extends, serves a useful purpose when the device is in a folded position.

The bent arm portion 25 of the arm 1 is spaced from the bent arm portion 26 of the arm 2 a distance approximately equal to the length of the unthreaded portion of the bolt 20. In order that the arms may be moved so that they are in alinement wh n in a folded position, it is necessary that the bolts be removed from three of the arms,

and for convenience such bolts are again in- 7 sorted in threaded openings 30, 31, 32 in the bent arm portion of the arm 1. It is here to be noted that if the arm 25 were not spaced from the arm 26, there would be substantially no threaded connection between the openings in the arm 25 and the threaded portion of the bolt 20, lVhen the arms are in a folded position, the bolts 20 may be moved within their respective threaded openings so that there will be a pressure exerted between the bent arm portions 26, 27, 28, which, in addition to the tightening of the thumb nut 6 upon the bolt 7, will serve to securely hold the arms in position.

While but one preferred construction of this invention has herein been shown, it is to be understood that changes and modifications may be made thereof without departing from the spirit and scope of this invention. V g

Having thus described the invention, what I claim as new is:

A rim holding stand,'comprising a plurality of arms provided at their outer ends with legs extending at an angle from the arms and adapted to rest on the ground to support the arms horizontally a distance above the ground, a pivot bolt held on the inner end of one of the arms, the inner ends of the other arms being mounted to swing on the bolt as the fulcrum, the said arms when in extended position radiating from the bolt and when in folded position overlying one the other, I the leg of the said bolt-carrying arm being spaced from the leg of the adjacent arm, and supporting bolts screwing in the legs and extending a proximately at a right angle thereto, th outer ends of the supporting bolts being adapted to support a rim, the leg of the said bolt-carrying arm being provided with a plurality of threaded apertures adapted to receive the supporting bolts removed from the other legs prior to swinging the arms into folded position.
