ture, these fittings being cast in one piece,

, To all wliomvz't may concern Be it known that I, ROBERT REACH, citizen of the United States, residing at Philadelphia, Pennsylvania, have invented certain new and useful Improvements in Gymnasium Apparatus, of which the following is a specification.

My invention relates to gymnasium or childrens playground apparatus, and my object is to provide a simple, effect-ive and inexpensive structure, and particularly to provide a fitting which may be assembled with stock material, such as metallic piping to make up the supporting frame and to provide the necessary hangers for the attachment of the exercising device.

-The invention consists inthe features and combination and arrangement of parts hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings: Figure 1 is a view of a gymnasium or playground structure in which the exercising device consists of traveling rings suspended by exible connections from the supportmg structure so that the user may swing himself from ring to ring; Fig. 2 is a view of my invention as embodied in connection with swings or swinging rings; Fig. 3 is a side view of one of the fittings with the suspending roller in place, this roller being adapted to support anV exercising device, the movement of which is transverse in respect to the main beam; Fig. 4 is a.

plan view of the lower cap of this fitting;

Fig. 5 is a detail view of a litting, the

roller of which has its axis transverse in respect' to the main beam; Fig. 6 is a detail view of the tting adapted'to connect with a vertical standard; and Fig. 7 shows the manner of connecting the diverging standards or braces with the main beam. Fig. 8 is a view of another form of fitting; Fig. 9 is a view of Fig. 8 a quarter turn therefrom; Figs. 10 and 11 are Aviews of the roller suspension device; Fig. 12 is a view like Fig. 8, but of a fitting adapted for a swinging action in a direction longitudinally of the main beam; Fig. 13 is a view of Fig. 12 a quarter turn therefrom.

In these drawings, the main beam or supporting member is indicated at 1, made up of three metallic pipes. These are secured together -by inserting them in fittings 2 arranged at different points along the struc-- and each having three sockets, one for each' of the metallic pipes which are secured in place by set screws 3. The pipes are arranged with two in a lower plane parallel with each other, and with the third -pipe elevated in respect to the pair of pipes, and over the space between them. The fittings have also cast therewith a depending portion 4, to which is attached a bearing'por tion 5. The parts 4 and 5 have a substantially circular opening therein, the inner walls of these parts being provided with a rib 6 projecting inwardly, adapted to lit in a peripheral groove 7 of a roller 8, which is provided with laterally extending ears 9 having openings 10 to receive the suspension connections, which consist preferably Of chains 11, the upper end of said chains having diverging portions 12 to connect with the ears 9 on each side of the roller. In order to fit the roller in place, the cap or lower portion 5 of the fitting is removed from the main portion; the roller is then inserted, and the cap is again bolted to the main portion. Where, as in Fig. 1, the structure is intended for use with traveling rings in which the motion Of the exercising device or ring is longitudinal of the framework, the roller is arranged to turn in a plane longitudinally of the structure; but

swing transversely of the structure, the sus pending roller is arranged with its axis parallel with the longitudinal axis of 'the main beam. The main beam may be supported in various ways, but at certain points I utilize the fittings above described as means of connection with the supporting standards, for which purpose the fitting which receives the three tubes or pipes of the main beam is provided with a depending socket 13, which receives the upper end of the vertical standard 14, the said standard being secured in place by the set screw 15. Diverging standards, as shown at 16, may be employed, the upper ends of which are held in sockets 17 of fittings 18 which receive the lower members'of the main beam, and similar diverging standards or braces may be employed at the ends of the Structure similarly secured by fittings to the extended ends of the lower members ofl the main beams.

It will be observed from the above struc.-v ture that the various fittings may be furnished to different purchasers or contractors, and by taking stock material, as the gas ipes or tubing, the entire structure may e assembled and set up for use.

In Fig. 8I show a form of tting for use with three pipe sections forming a main beam,A like in the forms before described,

but in this instance the fitting is made in three parts, 20, 21 and 22.' The lower member orcap forms a loop-shaped support for the roller, being ribbed as above described to fit the groove in the roller, and

yao

placed on the supports at any point, and

after. the main supporting structure is set up. As shown, these divided fittings in the one case shown in Figs. 8 andy 9,5 have their loops extending in a direction transversely of the pipes or tubes. In this form the central member of the clamp has a depending projection 24 to act as a retainer for the roller.

In the form shown in Figs. 12 and 13, the loop for holding lthe roller extends in a direction parallel with the pipes or tubes.

' v By these fittings the provision is made for supporting either swings or traveling rings. In the form shown in Figs. 12 and 13, a

projection 23 .acts as a retainer for the roller. v

The roller is shown in Figs. 10and 11, it having a groove to receive the rib on the loop and -having vdepending ears to receive the chains or ropes which support the swing.

It will be observed that the4 roller from which the suspending connections extend downwardly is held in place in the opening in the lower portion of the itting,the said roller interlocking with the wall of the opening and having a peri heral bearing thereon, no axial bearing eing employed, but instead axial projections are provided for the attachment of the suspending means. The stop 24 in Fig. 8 and 23 in Figs. 12 and 13 is formed separate from the lower portion having the opening for the roller, and thus when the parts are separated the rollery can be removed, the stop of course being withdrawn. By providing a squarehole in the depending ear of the roller as shown in Fig. 11, a hook rectangular in cross section may be v'used at the top of the suspend- -or tubes, ittings to tie the bars to suspension means for an exercismg device ing chain by which the ears are in effect provided with rigid extensions to increase the leverage action'on the roller.-
