SWING.

Application nled November 12, 1921.

To (1.7K whom. it may concern:

:86 it known that we, Gjuoncn MANIKOWSKE and lVARnnN J. 'GAnLsoN, citizens of the United States, residing at Minneapolis, in the county of Henncpin and State of Minnesota, have invented certain new and useful Improvements in Swings; and they do hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in swings of the type having means whereby the occupant may start and propel the same by foot and arm movements and is in the nature of an improvement on the Clipfell and Manikowske U. S. Letters Patent 1,335,938, issued April 6th, 1920.

To the above end, generally stated, the invention consists of the noveldevices and con'ibimxtions ct devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a perspective view of the improved swing;

Fig. 2 is a view principally in vertical section taken on the line 22 of Fig. 1 on an enlarged scale; and

Fig. 3 is a detail view with some parts sectioned on the line 3-3 of Fig. 1.

The numeral 1 indicates an overhead swing support in the form of a beam, to which is rigidly secured, a pair of edgewise spaced, transversely extended head plates or bars 5. To the ends of these plates 5 are secured front and rear pairs of depending swing supporting hooks 6 and 7, respectively. It is important to note that the forward ends of the plate 5 are downwardly offset to position the front pair of hooks 6 at a lower elevation than the rear pair of hooks 7 The improved swing includes a seat 8' rigidly secured to the lower ends of a pair of suspending rods 9, which in turn, are suspended by cables 10 from the rear pair of hooks 7 The suspending rods 9, at their lower ends, extend through bores in the ends of the seat 8 and are rigidly secured thereto by opposing nuts 11 having screwthreaded engagement therewith.

Serial No. 514,814.

To brace thesuspending rods 9 and thereby hold the same against angular move ment in respect to the seat 8, there are provided segmental brace bars, 12 which extend transversely over the seat 8, and have in their crowns, bores 13 through which said rods extend. The braces 12 extend from the front to the rear edges of the seat 8 and their lower end portions are extended toward each other on the bottom of said seat and are rigidly secured thereto, by the suspending rods 9 and the nuts 11, and nut-equipped bolts 14:.

The upper ends of the suspending rods 9 are bent to form eyes 15, to which the suspending cables 10 are attached, and then extended laterally toward each other and connected by a coupling 16 to aiford a tierod 17. This tie-rod. 17 serves a double purpose, in that it holds the suspending rods '9 in parallel arrangement and from being pulled apart at their upper ends,

either by accident or otherwise, and it also prevents the occupant of the swing from standing on the seat 8.

Sleeve-like handles 18 are slidably mounted for endwise movement on the suspending rods 9 and have secured to each of their ends, by screw threads, bearing heads 19.

These bearing heads 19 have sockets 20 in which are mounted bushings 21 having direct engagement with the suspended rod 9, and hold the handles 18 and bearing heads 19 out of engagement therewith. The bushings 21 are preferably made from pieces of hardwood, which, previous to their application to the bearing heads 19, have been boiled in parafline and which parafiine acts as a lubricant for the bushings on the sus pending rods 9.

Formed'with the bearing heads 19, are cup-like guard flanges 22 which prevent the occupant of the swing or a. person taking hold of the suspending rods 9, while the swing is in motion. from being pinched between the handles 18 and said rods. It is obvious that, when the swing moves downwardly the handles also slide downwardly on the rods 9. If, at this time, thehands of the swing-occupant happen to be grasping the rods 9, below or above the handles, they are engaged by the the lower rim of the cups 22 and prevented from contact with that portion of the rod which passes through the bushing 21, and hence cannot become pinched between the bushing and said rod.

The handles 18 are held suspended on the rods 9 by pulling members or cables 23, the upper ends of which are secured to the front pair of hooks 6 and their lower ends are secured in eye-equipped lugs at on the upper pair of bearing heads 19.

A horizontal foot rest 25 extends in front of the seat 8, and below the same, and is in the form of two endwise positioned rods, the outer end portions of which are extended laterally and upward, to afi'ord a pair or arms 26 attached to the lower pair of bearing: heads 19 by screw threaded engagement.

v[is shown the two rods forming the foot rest 25 are connected by a coupling 27 having screw-threaded engagement therewith.

The suspending cables '10 and pulling cable 23 are releasably attached to the hooks 6 and 7 by blocks 28, preferably of fiber, and have bores to receive said hooks and also have a plurality of bores through which said cables are laced to adjustably connect the same thereto.

The purpose of attaching the pulling cables 23 at a lower elevation than the suspending cables 10, and the manner of setting up and maintaining motion to the swing is fully set forth in the patent hereinbefore identified and for the purpose of this case it is not thought necessary to again re eat the same.

' at we claim is:

1. A swing comprising a seat, suspending members attached to the seat, and sleeve-like handles slidable on said suspending members and having flaring end portions of greater internal diameter than the intermediate portion of said handles, whereby to hold the hands of the swing occupant away from the points of contact between the handles and the suspending members, during the motions of the swing, substantially as described.

2. A swing comprising a seat, a pair of rods extending through bores in said seat and rigidly secured thereto, arch-like braces extending transversely over the seat from the front edge to the rear edge thereof and having in their crowns bores through which said rods extend, the end portions of said braces being extended transversely under the seat and rigidly secured to the bottom thereof, and a pair of suspending cables attached to the suspending rods.

In testimony whereof we afiix our signa- I tures.
