EPECIFICATION forming part of Letters Patent No. 323,121, dated July 28, 1885,

Application filed October 18, 1884. (No model.)

To all whom it may concern:

Be it known that LJOHN T. Dnns,of Goldsborough, in the county of WVayne and State of North Carolina, have invented a new and Im proved Swing,of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved swing, which is so constructed that it can readily be operated by the person so ccupying the swinging car, and which swing can be stopped very easily and rapidly.

The invention consists of the combinations of parts, including their construction,substantially as hereinafter fully set forth and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification,in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view of my improved swing, parts being broken out and parts being in section. Fig. 2 is a sectional plan view. Fig. 3 is an enlarged detail longitudinal view of part of the car orboX. Fig. 4 is an enlarged sectional view of my improved hanger.

From a base-iran1c, A, a series of inclined posts, 13, project upward and toward each other and support a cross-bar, 0, from which theswingis suspended. Two segmental tracks, D, having the concave edges toward the top, are secured to the posts B and to the base.

From the top cross-bar,O, a bar, E, is hung to swing by means of hangers F, and at the ends of the bar E eyebolts F project from the side edges, to which eyebolts the upper ends of chains, cables, or wires G are secured, the lower ends of which are secured on the free ends of arm H of shafts J, journaled transversely in the end parts of theboX, car, or cage K, the arms H being outside of the car.

Each shaft J is provided with an upwardlyprojecting arm,L,within the car and at right angles tothe arms H.

Each arm L is provided with a notch, M, for receiving the free end of a locking pawl or latch, L'pivoted t0 the car.

Each pair of ropes or wires G-that is, the ropes or wires at each end of the car-are uni ted by a cross-piece,N,at abouthalf thelength,and to each piece N a rope or wire, 0, is secured, which passes over a grooved pulley, P, in the end of a standard, 1?, or upwardly-projecting arm at the opposite end of the car, and is then fastened to one end of an elbow-lever, Q, pivoted on the same end of the car and having a handle, Q, on itsinner end.

From the bottom of the car,which is curved the same as the runners, two guards, It, project downward adjacent to the inner sides of the curved tracks.

Small rollers S,adapted to run on the curved tracks, arejournaled in the bottom of the car K.

In each rope or wire G a turn-buckleflV, is provided a few feet above the car,to permit of tightening the ropes or wires,as may be necessary.

The hangers F are each formed of a heavy bolt, f, provided with a transverse aperture, 9, having a recess, h, in its bottom for receiving a projection on the bottom of a pin, Z, passed transversely through the aperture in the bolt, the said projection passing into the above-mentioned recess h, whereby the friction is reduced and easy working of the parts is obtained. The pin Z is secured at its ends in bolts an, secured in the bar E. Asafety-rope, m, is passed through the bar E and through the top cross-piece,0, so that in case the hangers break the bar E cannot drop on the persons in the car.

To start and operate the swing,two persons at opposite ends of the car pull the levers Q upward alternately, and the ropes O pull on the cross-pieces N, thereby pulling the ropes on wires G alternately toward each other. Thereby the center of gravity of the car is dis placed alternately to opposite sides and the car begins to swing,first,slowly,and then more rapidly, and when once in full swing requires but little power to operate it. \Vhen the swing is to stop, the arms L are disengaged from thela'tches Land then swung down,whereby the arms H are swung up and the ropes' G slackened slightly, thus permitting the car to descend to the curved track D,upon which it rests, the rollers S running on the said tracks. The car runs down to the lowest points of the tracks and then comes to astandstill. To operate the swing again, the arms L are swung up, thereby swinging the arms H down and drawing the ropes or wires G taut, whereby the car is raised sufficiently to clear the tracks. The arms L and the shafts J are then looked in place by means of the latches r pawls I.

In case any of the parts break, the car cannot drop any farther than upon the tracks,

down which it slides.

Having thus described my invention,I claim as new and desire to secure by Letters Patentl. The combination, with aswing-frame, of segmental tracks held on the same,a swinging car or boX,and guards projecting from the bottom of the same at the sides of thetracks,substantially as herein shown and described.

2. The combination, with a swing-frame, of segmental tracks held on the same, a swinging ear or box, guards projecting downward from the same, and rollers journaled in the bottom ofthe car orbox, substantially as herein shown and described.

3. In a swing,the combination,with aswing car or box, of shaftsjournaled transversely in the same at the ends, arms on the ends ofthe shafts, to which arms the ends of the suspension ropes or wires are secured, a handle or arm for turning each shaft, and devices for locking the shafts in place, substantially as herein shown and described.

4. In a swing,the combination,with a swinging car or boX, of ropes or wires by which the car is suspended,a rocking elbow-lever at each end of the car, and a rope or wire secured to the elbow-lever and connected with the suspending ropes or wires at the opposite end of the car, substantially as herein shown and described. i

5. In a swing,the combinati0n,with aswinging car, of ropes or wires by which it is suspended, a rocking elbow-lever at each end of the car, astandard at each end of the car, a pulley on the top of each standard, a rope secured to each elbow-lever passed over the pul ley on the top of the standard and connected with the opposite suspending ropes or wires, substantially as herein shown and described.

6. The combination, with a swing-frame, of the bar E,suspended from the cross-piece of the frame by hangers, a car suspended from the bar E, and of a safety-rope, m, passed through the cross-piece C of the frame and through the barE, substantially as herein shown and described.

7. In a swing, the combination, with the swinging car K,of the shafts J, having arms H, the arm L, having a notch,M, and the latch or pawl I for locking the arm L in place, substantially as herein shownand described.

8. In a swing, the combination, with the bolt f, having an aperture, 9, having a recess, h, in its top,of the pin Z, provided with a projection and held at its ends by bolts m, substantially as herein shown and described.
