SWING.

Specification of Letters Patent.

, Patented Dec. 28, T92@.

Application filed March 19, 1920. Serial No. 367,097.

To (ill whom it may concern: Be it known that LDAvm 1. BROWN a citizen of the United States, residing at incinnati, in the county of Hamilton and State of Ohio have invented certain newv and useful Improvements in Swings, of which the following is a specification.

TlllS invention relates to swings, and has for its general object to produce a novel.

and improved swing wherein an improved suspension structure is provided to regulate the path of travel thereof and to prevent its undue tilting, twisting or lateral motion from its main plane of travel.

Another object of the invention resides in a swing wherein the suspension structure is formed to embodya pair of parallel cable members whose upper ends are designed for swinging connection with a stationarysupport, the lower ends of said cable members eing connected with a suitable form of seat structure which is so formed as to cause a swing to travel in 'a plane longitudinal therewith, one of said cable members hav ing its upper end connected with a swinging armwhich has its upper end connected with the stationary support on the same horizontal plane as the connection between the other cablemember and the stationary member, the lower end of said arm being movably connected with one of the cable ,members, this arrangement of parts being such that when the swing is moving in its proper longitudinal direction the cable.

members are swinging from the, same horizontal plane, but in the event of lateral movement on the part of the seat structure,

- the cables will be caused to swing from different planes, thus causing the seat structure to quickly assume its normal path of movement so as to effectively prevent such undue travel. 7

Other objects reside in an lmproved swlng of economical and simple construction, ca of being readily erected and designed pivotally pable to. furnish considerable amusement and pleasure to thoseusing the same.

For a more complete understanding of the invention, reference is to be had to the following description and to the accompanying drawing, whereinigure 1 is a perspective view of the swing comprising the preferred form of the present invention, and Fig. h structure thereof.

2 is a detall sectional view of the the hook 5 so as to provide a swinging support for the seat structure. The cable 3 extends approximately the full height of the swing and is provided contiguous to its lower end with a coil spring 6 by means of WhlCh the seat structure is rendered more or less resilient and the use of the swing is thereby rendered more comfortable than if a rigid connection were to be employed. The extreme lower end of the cable 3 is provided with an eye 7, which engages with I the hooked forward end 8 of the seat structure 1. The latterispreferably formed so as to provide an enlarged seat portion 9 and a reduced forward portion 10, the con-- struction of the seat being such that the limbs of the user may freely extend downwardly so as to effect the propulsion of the swing. A back rest 11 is'provided upon the rear end of the seat structure by means of hook bars 12, with which the divided lower ends 13 of the cable 2 are secured. These endsconverge upwardly and are joined to the main body of the cable 2 by means of the 8 link 14. By meansof this divided. construction of the cable 2 a nontiltable support for the seat structure is provided;

The upper end. of the cable 2 is connected 7 with the lower hooked end 15 of a swing ing arm 16, said arm being so arranged as to lie co-extensively with the upper end 0 the cable 3. The upper end of the arm is connected as at 17 with a metallic bracket 18 carried by the stationary support 4. I v I From the foregoing it will be observed that when the seat structure is traveling in its normal longitudinal plane, its cables will swing from a common horizontal plane,- this being caused by placing the pivot 17 on sub stantially the same horizontal plane as the hook 5. This arran ement causes the cables to oscillate in para ehsm. However, in the without liability of accident. The swing as event of lateral movement on the part of the seat structure it will be manifest that the cables will oscillate from different horizontal planes, that is, the arc of swinging movement of the front cable will be greater than plane only and therefore any undue lateralmovement on the part of the seat structure will be readily taken care of and prevented by the cable suspension. All of this construction contributes toward a swing whose construction "is simple and free to manipulate and yet may be safely used by children will be manifest, is of staunch and simple construct1on,'may be cheaply manufactured and possesses attractive and pleasing outlines.

v 1 said member lying in parallelism with said What is claimed is: i

1. A swing comprising a seat structure, a pair of cables connected to the opposite longitudinal ends-of said structure, one of said cables being directly connected for swinging movement with a main stationary support, the other of said cables having its upper end similarly connected with a hinged memberpivotally carried by said support cables and operating to permit said cables to swing from the same horizontal plane when the swing is moving longitudlnally but from different horizontal planes upon lateral movement of the swing.

cable.

2. A swing comprising a pair of spaced parallel cables, a seat structure secured to the lower ends of said cables, and means cooperative with the upper ends of said cables to permit the latter to swing on substantially the same horizontal plane upon longitudinal movement of the seat structure but on different horizontal planes upon lateral movement of said seat structure.

3.-A swing comprising a pair of spaced cables, a connection between the upper end of one of said cables and a stationary support, an arm pivotally movable in the longitudinal plane of said swing, the lower end of said arm beingconnected with the upper end of the other of said cables, and a seat structure carried by the lower ends of said cables, said arms serving to permit said ca- .bles to swing from substantially the same horizontal plane when the swing is moved longitudinally but from different horizontal planes upon lateral movement on the part of the swing. 4

4. A swing comprising a seat structure including a back rest and a reducedforward extremity, a cable having its upper end adapted for connection with a supporting member, the lower end of said cable being secured to the forward reduced portion of said seat structure, a second cable having a divided'lower portion secured to the back rest of said seat structure, a hinged armpivoted to said supporting member on substantially the'same horizontal 'iplane as the connection between said supporting member and the upper end of said first named cable, and the lower end of said arm being connected with the upper end of said second whereof I afiix m si ature.
