Specification of Letters Patent. Patented 31 21,

Application filed April 27', 1920. Serial No. 376,969.

T0(r71w/zm/titmcy concern:

Be it known that we, Finn) Wrrnnnrs and Lonnxrs II. S'rrxvio, citizens of the Iinited States. and residents of Bellingham, county of \Yhatcom, and State of \Vashington, have invented certain new and useful Improvements in Horizontal Bars, of which the following is a specification. f

This invention relates to supporting strncture for horizontal bars, and has for its principal object toprovide collapsible frame members which may be extended to functional position to hold and rigidly support a horizontal bar or the like, and which may be folded together, or collapsed to release the bar and permit it to be packed or stored with the frame members in a minimum amount of space.

It is also an object of the invention to provide supporting frames of this character of simple and durable construction which will substantially support a bar against lateral or longitudinal strain and yet have no fixed connection therewith; which allows quick and easy disassembling of the parts.

In accomplishing these and other objects of the invention, we have provided the improved details of structure, the preferred forms of which are illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view of a set of bar supporting frames embodying the pres ent invention in functional position.

Figure 2 is an end view of the same. show ing in dotted lines, the manner of folding the legs together to release the bar, and showing extension members fixed to the legs.

Figure 3 is a view of a frame when in collapsed position.

Figure 4 is an enlarged detail View, illustrating a curved connecting bolt which secures the upper ends of the legs of a frame together.

Referring more in detail to the drawings: 1 designates a horizontal bar or the like, which is supported at its opposite ends by means of frame structures 2 embodying the present invention. Each of these frames comprises two legs, 3, which are spaced apart at their lower ends and at their upper ends have faces a cut on a bevel thereto, which are brought together in a vertical joint; thus forming an inverted V-shaped frame.

The 0 posed faces 4 of the providec with seats, or notches,

legs 3 are each 5, which as shown in Figures 1, 2 and 3, are semi-circular and register with each other so that,,when

tne legsare brought together they will act co-operatively to grip and seat the-end of a bar 1 therein.

Radiall curved bolts 7 extend sli'dably through apertures 8, adapted thereto atpoints a little below the upper ends of the legs. These bolts are provided with heads 9 at one end and have nuts 10 threaded onto their opposite ends which may be "adjusted to adapt the gripping or rod-supporting ends I to various sizes of rods. The slidable mounting of the bolts also permits folding of the legs together, as is shown in Figure 3.

At their lower ends, the legs are spaced apart and braced by a pair of hingcdly connected bars 12 and 18, which, at their outer ends, are also hingedly connected to the legs. This particular manner of bracing limits the spread of the legs, normally prevents them from being moved together, but permits folding of the paired bars together, on moving their hingcdly connected ends upwardly, so that the legs may be moved together and thereby release the bar from the notches at their upper ends.

It is also .desired that the notches 5 extend across the faces 4: in a manner that when the bar 1 is seated it will cause the frames to be inclined toward each other at their upper ends and will thus brace the bar against longitudinal movement. It is also desired to provide the base of each leg with a shoe or pad of rubber, or the like, 20, which will prevent slipping.

In Figure 2 we have illustrated the attachment of extension legs 15 tothe legs 3. This is done by extending the lower ends of the legs 15 through loops formed by bands 16, fixed to the lower ends of the legs 3 and securing their upper ends to the legs 8 by bolts 17, which may be extended through registering apertures 18 in the legs.

In Figure 4 we have illustrated the mounting of a square bar in the supporting frame. In this construction the notches 5 are cut square instead of semi-circular notches, and may be made to correspond to the character of the bar used, and may be semi-circular, square, semi-hexagonal, many other neces sary or desired shape to fit correspondingly shaped ends of the bars supported.

In using frames of this character, it 18 only necessary to place the end of a bar within the notches 5, and to spread the legs apart, as in Figure 2, to draw ends of the legs tightl a ainst the opposite sidesof the bar en he tension with which the legs grip the bar ends may be ad-, justed by ad ustment of the nuts at the ends of the bolts. 1

To release the bar, it is only necessary to pair of diverging legs cut on a bevel at their the upper upper ends and adapted to be fitted to gather in a vertical joint, the beveled portions having notches cut therein to cooperatively receive and support an end of the bar therein, a bolt curved radially about the bar and functionally connecting the legs at points below the upper ends and having an adjustable nut at one end thereof and extending slidably through apertures in the legs, and collapsible brace members connecting the lower ends of the legs adapted to be extended to spread the legs apart to force them together at their upper ends to grip the bar .and to be folded together to permit the upper ends to release the bar.

Signed at Bellingham, Whatcom County, Washington, this 14th day of April, 1920.
