JULIUS J. KARGES, OF JACKSON COUNTY, MISSOURI.

FRICTIONAL GLAMPING DEVTCE.

To all whom it may concern:

Be it known that I, JULIUs J. KARGES, a citizen of the United States, residing in Jackson county, in the State of Missourl, have invented a certain new and useful Improvement in Frictional Clamping Devices, of which the following is a specification.

My invention relates to improvements in frictional clamping devices.

It is particularly adapted for use in connection with display stands which employ sliding members for supporting goods to be displayed. I

My invention provides further a novel d1splay stand which may be readily adjusted to suit the purposes for which it may be employed, which is cheap to manufacture, 1s light in weight, which is durable and whlch is not liable to get out of order.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing which illustrates the preferred embodiment of my invention, Figure 1 is a perspective view of my improved display stand provided with two of my improved frictional clamping devlces. Fig. 2 is a side elevation of one of my improved clamping devices detached from the stand. Fig. 3 is a view similar to Fig. 2 showing a rod held clamped between the members of my improved clamping device. Fig. 4 is an enlarged longitudinal vertical sectional view of an end portion of my improved clamping device.

Similar reference characters designate v similar parts in the different views.

1 designates the base of the display stand, 2 a tubular standard secured to and extending upwardly therefrom, 3 a vertical stem slidable in the standard 2, and having a lateral arm 4 secured to one side of a rectangular wire frame 5 which is horizontally disposed.

Mounted on the frame 5 are one or more of my improved clamping devices, each comprising two resilient members, preferably consisting of two flat spring bars, of steel or other suitable material, designated respectively by 6 and 7. The end portions of the bar 6 are reversely bent to form inwardly extending arms 8, disposed on the same'side of the bar 6 and provided respectively with means slidablyengaging the adjacent ends respectively of the bar 7. Such means preferably consists of two pins 9 which extend through holes provided therefor in the bar 6 Specification of Letters Patent. Patented Ma a "7 1 916 Application filed June so, 1915. I

and through holes provided therefor in the arms 8 respectively. I The bar 7 near its ends 1s provlded with two holes through which the pins 9 respectively extend.

The ends of the bar 7 are disposed between the bar 6 and the arms 8 and are respectively adapted to be .moved longitudinally relatively to said pins.

The inner ends of the arms 8 normally bear against the adjacent side of the bar 7, the latter being bow shaped and having its convex side bearing, adjacent to the middle of the bar, against the adjacent side of the bar 6, which is, preferably, also bow shaped.

and has its convex side against the bar 7, as shown in Fig. 2.

As shown in the drawing, the bar 7 adacent to its ends, and adjacent to where it bears against the ends of the arms 8, is bent toward the bar 6.

By means of the construction just described, when a wire or rod of the proper diameter is inserted transversely, as the rod or wire, 10 in Fig. 3, it may be slid between the bars 6 and 7 from one'pin 9 to the other pin 9, and at all points between said pins will be held clamped by the bars 6 and 7 with substantially the same spring pres. sure. This permits the clamping device to be slippedonto the frame 5, as shown in Fig. l, and to firmly clamp said frame in any position thereon to whichthe clamping device may be adjusted longitudinally or laterally. At the same time the yielding clamping pressure permits of the easy and quick adjustment of the clamping device to the position desired.

By providing two clamping devices mounted on the frame 5, as shown in Fig. 1, they may serve as two oppositely extending arms for supporting the goods to be displayed. V

The arms 8 are preferably inclined toward their ends and toward the body of the member 6, and their ends bear upon the member 7 at points 11, respectively at substantial distances from the ends of the member 7, so that too great a pressure will not be exerted against the rod or wire 10 when it is forced past said points 11 topositions adjacent to the pins 9. The end portions of the member 7 are preferably inclined from said points 11 toward their ends and toward the body of the member 6 so that such end portions may exert sufficient pressure upon the rod or wire 10.

WVith the construction described, the rod or wire 10 or the frame 5 will be clamped by a substantially uniform pressure in any po sition to which it may be adjusted.

While I have shown the pins 9 as employed for attaching the members 6 and 7 together, other suitable means may be employed.

I have shown the clamping device as forming a part of a display stand, but it is obvious that it may be put to many other uses where it is desired to obtain a uniform sliding clamping engagement of the device with another article.

I do not limit my invention to the structure shown and described, as modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention.

WVhat I claim is 1. A frictional clamping device comprising a resilient clamping member having at its ends arms inwardly turned at one side of said member and spaced apart therefrom, and a second resilient clamping member normally bearing between its ends against the first named clamping member and having its ends respectively disposed between said arms and the first named clamping member, the ends of said armsnormally bearing against the second clamping member intermediate of the ends thereof.

2. A frictional clamping device comprising a resilient clamping member having two arms, one at each end, inwardly turned at one side of said member and spaced apart therefrom, a second resilient clamping member normally bearing intermediate of its ends against the first named clamping member and disposed between said arms and the first named clamping member and normally bearing intermediate of its ends against said arms, and securing means for holding the two members attached to each other and relative to which one of said members is transversely movable.

3.
