DISPLAY-STAND FOR TIRES.

Specification of Letters Patent.

Patented June 8, 1920.

Application filed May 10, 1.919. Serial No. 296,094.

To all whom it may concern:

Be it known that 1, CHARLES W. YELM, a citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Display-Stands for Tires;. and I do declare the following 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, reference being had to the accompanying drawings, and to the charac ters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in stands or supports for tires, being more especially intended for use in connection with the display of automobile tires in store windows, my object being to provide a device of this class which shall be simple in construction, economical in cost, which may be easily applied to the tire, and which will efficiently perform the aforesaid function.

Generally speaking, the device consists of a base of suitable area to give stability to the structure when a tire is in position, from the center of which base extends upwardly a short pedestal, above which is provided a socket member adapted to receive two jaws, which grasp the automobile tire on opposite sides when the device is in use. The pedestal and the base are perforated to receive a bolt, which is fastened. underneath the base bya nut, the head of the bolt above engaging the lower extremities or arms of the jaws in adjustable relation, the socket having laterally disposed grooves which receive outwardly projecting parts of the jaws, whereby the latter are fulcrumed intermediate their extremities, so that as the nut is tightened or loosened on the lower extremity of the bolt, the head of the latter, acting on the lower arms of the jaws or the parts below their fulcrums, will cause the jaws to approach or allow them to recede from each other, as circumstances may require, and depending upon the size of the tire with which the stand is to be used.

Having briefly outlined my improvement, I will proceed to describe the same in detail, reference being made to the accompanying drawing, in which is illustrated an embodiment thereof.

In this drawing:

Figure 1 is a side elevation of my improved stand, showing the same in use, with a tire, which is partly broken away.

Fig. 2 is an end view of the stand shown in detail and on a larger scale.

Fig. 3 is a central, sectional elevation of the device.

Fig. 4 is a side elevation in detail of one of the tire-engaging jaws.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the base, 6 the pedestal, 7 the socket member, 8 each of the jaws, 10 the adjusting bolt and 12 the nut applied to the lower extremity of the bolt. The parts 5, 6 and 7 preferably, and as illustrated in the drawing, consist of an integral casting, the base being elongated in a direction to give stability to the stand when the tire is in place, as best illustrated in Fig. 1. This base is hollowed out underneath, as shown at 13, to make room for the protruding threaded extremity of the bolt,

and for a suitable range of adjustment by the operation of the nut, 12, which is provided with a lever arm 14: to facilitate operation. The pedestal 6 is centrally perforated vertically to receive the bolt 10, whose head 16 extends upwardly into the socket or cavity 15 of the member 7. The socket 15 is centrally of such depth as to allow a considerable range of vertical adjustment for the bolt in order to properly regulate the position of the jaws which grasp the tire 17 on opposite sides. Each jaw is provided intermediate its extremities with an outwardly projecting bead or lug 18, which engages a groove 19, formed by the overlapping or inwardly projecting side edge 2!) of the member 7, whereby the jaws are fulcrumed, each jaw having a relatively long member 21 above the fulcrum, and a short member 22 below the fulcrum, the arms 22 of both jaws being located entirely within the cavity or socket of the top member 7 of the structure.

The arms 22 of the jaws extend inwardly toward each other when the parts are assem bled, and are engaged by the under surface of the head 16, preferably square, of the bolt, the projecting parts of the head on opposite sides forming shoulders which act on the inner extremities of the arms 22, for purposes of adjustment. As the head of the bolt is drawn downwardly by turning the nut 12 in the proper direction, the upper arms 21 of the jaws will be drawn inwardly,

as may be required, in order to grasp the adjacent portions of the tire on opposite sides with reasonable tightness.

Where tires are placed in a stand of this kind for display purposes, the inner tubes may be in place, the tire being mounted on a rim and inflated, whereby it becomes practicable to adjust the nut 12 to cause the jaws to grasp the tire with sufficient force to retain the same securely in place without tending to collapse or crush the tire, as will be readily understood, in view ofv the aforesaid conditions. With heavier or stifier casings, the inflation and rim mounting are not necessary.

In applying the device to a tire, it may preferably be inverted during the operation, or applied to the portion of the tire then uppermost, since by so doing access is more easily gained for the purpose of adjusting the nut. However,' after the stand is secured in place, the position of the tire may be reversed to-bring the stand in the lowermost and supporting position with the tire extending upwardly therefrom, as indicated in Fig. 1.

Attention is called to the fact that the lower arms 22 of the jaws 8 engage the head 16 of the bolt to prevent the latter from turning when the nut 12 is adjusted. The head of the bolt must be of such size with reference to the spacing of the arms 22 on opposite sides, that the head of the bolt is locked against turning.

It should also be explained that the central portion of the lower edge of each jaw is provided with a recess 25, whereby these recesses are on opposite sides of' the shank of the bolt, thus permitting the arms 22 of the jaws to move inwardly farther toward the bolt than would otherwise be permitted.

I claim:

1. A display stand for tires, comprising a base member, means to engage a tire, a jaw member to clamp the tire, one of said members having a projection and the other a groove to receive the projection, whereby and engaging the lower parts of the jaws for purposes. of adjustment.

a. A display stand for tires comprising a base having an open cavity in its upper portion, jaws loosely and removably fulcrumed in said cavity, and means for adjusting the aws.

J 5. A device of the class described, comprising a base, having an open cavity in its upper portion, jaws loosely and removably fulcrumed in said cavity, the base having a central vertical opening communicating at its upper extremity with the cavity, a bolt movable in said opening, the headof the bolt engaging the jaws below their fulcrums, and a nut applied to the lower end of the bolt.

6. A display stand for automobile tires, comprising a base, opposing tire-engaging jaws fulcrumed on the upper portion of the base, a bolt vertically movable in the opening, extending through the base, the head of the bolt acting on the jaws, and means for adjustably securing the bolt in place, the jaws having faces engaging the head of the bolt to lock the latter from turning.

7. A display stand for automobile tires, comprising a base, opposing tire-engaging jaws fulcrumed on the upper portion of the base, a bolt vertically movable in the opening, extending through the base, the head of the bolt acting on the jaws below their fulcrums, and means for adjustably securing the bolt in place, the lower portions of the 105 jaws being arranged in such proximity to the head of the bolt as to lock the latter against turning during its vertical adjustment.

8. A display stand for automobile tires, 110 comprising a base, opposing tire engaging jaws fulcrumed on the upper portion of the base, a bolt vertically movable in the opening extending through the base, the head of the bolt acting on the lower portions of the 115 jaws, and means for adjustably securing the bolt in place, the lower portions of the jaws being arranged in such proximity to the head of the bolt as to lock the latter against turning during its vertical adjustment.

In testimony whereof I aifix my signature.

CHARLES WALTER YELM.
