HORIZONTAL-BAR STRUCTURE FOR GYMNASIUMS.

Specification of Letters Patent.

Application filed May 29, 1911.

Patented Sept. 19, 1911.

Serial No. 629,997.

To all whom it may concern:

Be it known that I, MILTON B. REACH, citizen of the United States, residing at Springfield, Massachusetts, have invented certain new and useful Improvements in Horizontal-Bar Structures for Gymnasiums, of'which the following is a specification.

My invention relates to a horizontal bar structure particularly adapted for use in gymnasiums where galleries are provided, and it consists in the features and combination and arrangement of parts hereinafter described and pointed out in the claims.

In the accompanyin drawings Figure 1 is an end view of the orizontal bar structure in place in connection with the gallery of the gymnasium; Fig. 2 is a front view of the part shown in Fig. 1; Fig. 3 is a plan view of the arrangement of the hoisting ropes.

In these drawings,-1 indicates the gallery with which the gymnasium is provided having a railing 2 and a supporting beam 3. The horizontal bar 4 is arranged at a suitable distance from this gallery, and par allel therewith, the ends of the horizontal bar being connected with the gallery by braces consisting of rods 4, preferably of one inch pipe. These brace rods are pivoted to the supporting beam 3 of the gallery at the points 5. From the ends of the horizontal bar supporting cables 6 extend upwardly, as shown in Fig. 1, and at an inclination rearwardly toward the side wall of the gymnasium, the upper ends of these sup-porting cables being connected with a supporting rod or pipe 7 which is suitably mounted on the frame work of the building. Suitable turn buckles are provided at 8 for securing proper tension of these su aporting cables or straining connections. l rom the ends of the horizontal bar other straining connections or cables 9 extend downwardly and these are connected with the floor through any suitable form of turn buckle or straining means such as the lever device shown at 10; for instance this may be of the form shown in Letters Patent of the United States granted to me August 24, 1909, No. 932,413. The cables or lower connections 9 I prefer to extend vertically, while, as above stated, the upper connections 6 extend backwardly at an inclination. When these cables or straining connections are placed under tension, the

bar to move in any direction will be resisted,

it being further observed that the supporting rods or tubes 4 extend upwardly at an inclination and also outwardly at an inclination, as shown in Fig. 2.

One feature of my present invention consists in the arrangement of the horizontal bar structure in connection with the ga1 lery, so that it may be conveniently sup ported thereon and may be raised from its position of use to occupy a position adjacent the gallery, where it would be out of the way and leave the floor space entirely clear. For this purpose the supporting tubes, as above stated, are pivotally mounted at the points 5, and a suitable hoisting rope 11 extends over a pulley 12 and having branches 13 and 14 passing around pulleys 15 and 16 to connect with the horizontal bar at or near the ends thereof. As shown in Fig. 2, the horizontal bar may be of double length, in which event there would be three sets of straining connections and three of the pivoted tubes or bars 1. In Fig. 1 I indicate in dotted lines the horizontal bar as having been hoisted to its position of non-use, this being accomplished by releasing the connections at 10 and drawing upon the hoisting rope 11.

I claim as my invention 1. A horizontal bar structure for gymnasiums comprising the bar proper, bracing rods connected wit-11 the bar acting as a carrier therefor, extending laterally therefrom, and pivotally mounted on a suitable supporting member, flexible straining connections extending upwardly from the horizontal bar and attached at a point overhead, flexible straining connections extending downwardly from the horizontal bar and attached to the floor, with suitable means for placing these connections under strain, and means for swinging the bracing rods on their pivots substantially as described.

2. A horizontal bar structure for gymnasiums comprising the bar proper, bracing rods connected with the bar, and pivotally extending mounted on a suitable supporting member, flexible straining connections extending upwardly from the horizontal bar and attached at a point overhead, and flexible straining connections extending downwardly from the horizontal bar and attached to the floor, with suitable means for placing these connections under strain, the upper straining connections inclining rearwardly in respect to the bar and the lower connections extending vertically, substan tially as described.

3. In combination in horizontal bar structures for gymnasiums, a bar proper, rods connected thereto extending laterally therefrom and inclining in respect-thereto, said rods being pivotally mounted to a supporting frame, and upwardly and downwardly flexible straining connections with means for adjusting the same, and means for swinging said laterally extending rods upwardly to raise the horizontal bar with its straining connections substantially as described.

4. In combination with the gallery of a gymnasium, a horizontal bar extending parallel wit-h the front of said gallery, rods pivotally mounted on the gallery extending laterally in respect thereto and connect ed with the horizontal bar, and upper and lower straining connections between the horizontal bar and the frame Work of the building, and means for hoisting the horizontal bar into position adjacent the gallery to thus clear the floor, substantially as described.

In testimony whereof, I aflix my signature in presence of two witnesses.

MILTON B. REACH.
