EPECIFICATION forming part of Letters Patent No. 320,319, dated June 16, 1885.

Application filed August 20, 1884.

To all whom it may concern.-

Be it known that I, THOMAS WILsoN, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsyl- Vania, have invented a new and useful Improvement in Swings, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 represents a side elevation, partly sectional, of a swing embodying my invention. Fig. 2 represents a front view thereof. Fig. 3 represents a view of a portion of Fig. 1 en larged. Fig. 4 is a top view of a detached part. 5 represents a section ofa detached portion enlarged. Fig. 6 represents a side elevation of a detached portion enlarged.

Similar letters of reference indicate corresponding parts of the several figures.

My invention relates to improvements in swings; and it consists of the construction and combination of parts, as hereinafter set forth, and particularly pointed out in the claims.

Referring to the drawings, A represents the seat of the swing, and B the supporting arms thereof.

0 represents the frame which sn 0 erossbeam D, the arms B depending therefrom and connected therewith by eyebolts E. The frame 0 is of the form of legs or shears, pivoted together, as at a,t-l1e upper ends whereof grasp or clamp the opposite sides of the beam D, whereby the beam is securely held in position.

Connected with the pivot or bolt a of each pair of shears are straps F F, one on each end of the bolt, the upper ends of the two straps for each shear being threaded and passing through a diagonallyarranged bar, G, which rests on the crossbeam D,whereby, by means of nuts I), the shears, pivotal bolts, straps, plates, and cross-beam are reliably connected, and a strong structure is provided.

On the cross-beam D, and extending at a right angle thereto, is an arm, H, to which the ropes J are attached, the latter being within convenient reach of the occupant of the seat for operating the swing, said arm H being secured to the cross-beam by means of a metallic truss, K, whose crown bears against the cross-beam, and whose ends are secured to the ends of the cross-beam by means of the eye- (No model.)

bolts L, to which the ropes J are fastened,the shanks of said bolts being threaded and secured in position by the nuts '0, it being noficed that the arm H is firmly held in place.

M represents a brake consisting of a bar which is pivoted or hung to the base of the frame C, whereby it may be raised and lowered beneath the seat A.

At the end ofthe brake-bar, opposite to its axis, is a crank-shaft, N, which engages with said bar, and is provided with a lever, P, it being seen that when the swing is to be stopped the lever P is operated, so that the brake-bar bears against the under side of the seat, and thus the swing is controlled and its motions prevented.

In order to permit the ready attachment of the arms B with the eyebolts E, and separation of the same, the bolts Q, which connect said parts, have their points hinged to the shanksthereof, forming gravitating latches or noses, which permit said bolts to be passed through the eyebolts and openings in the arms, said latches then dropping, as seen in Figs. 5 and 6, preventing the accidental withdrawal of the bolts.

By properly straightening the latches the bolts may be removed and the parts separated, as is evident.

It is evident that the parts of theswing may be readily taken apart and packed in compact form, it only being necessary to unscrew the several nuts, remove the bolts Q, separate the cross-beam, shears, &c., thus disconnecting the parts.

Vhen the frame C is set 11p, it is strengthened by braces A, each of which is connected with a pair of shears, and prevents shifting of the same, said braces being also removable,

as they are held in position by bolts and nuts.

If desired, the brake-bar may have a shoe on the upper face thereof. In Figs. 1 and 2 such shoe is shown on the under side of the seat, possibly the most suitable place for the same.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent. is-

1. A swing having the frame 0, in combi- H, secured to saidbeam D by a metallic truss, K, substantially as and for the purpose set forth.

2. A swin'ghaving the pivoted frame 0 O, and 5 the pivoted straps F F, having a common axial bolt, 1, said straps having threaded upper ends, the plate G, and nut b, said parts being arranged and combined substantially as and for the purpose set forth.

1o 3. A swing having an arm attached to the top cross-beam of the same, the same being provided with atruss and bolts, the latter connecting the truss with the cross-beam, and having eyes for the attachment of the ropes,

I 5 which are reached from the seat, substantially as and for the purpose set forth.

4. A swing provided with a brake consist ing of thecrank-shaft N, having lever P, and a pivoted bar, M, being attached to the frame of the swing and beneath the seat thereof, sub- 20 stantiall y as and for the purpose set forth.

5. In a swing, the seat A, in combination with arms B B, cross-beam D, eyebolts E, and bolt Q, said bolts E being secured to said cross-beam, substantially as and for the pur- 25 pose set forth.
