To all whom it may concern:

Be it known that I, WILLIAM C. BALL, a citizen of the United States, residing at Ewing, in the county of Jackson, State of Indiana, have invented certain new and useful Improvements in Portable Swings; and I do hereby declare the following to be 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.

This invention relates to portable swings and has for an object to provide a foldable swing frame in combination with a removable swing seat to permit of the swing being collapsed into a small compact bundle for storing or shipping.

A further object is to provide a collapsible swing frame having the legs adjustably connected together in such a manner as to permit of the legs being rocked from divergent relative position to about parallel relative position and vice versa.

With the above objects in view the invention consists of certain novel details of construction and combination of parts hereinafter fully described and claimed, it being understood that various modifications may be made in the minor details of construction within the scope of the appended claim.

In the accompanying drawings illustrating this invention: Figure 1 is a front elevation of the swing. Fig. 2 is a side elevation of the swing. Fig. 3 is a front elevation of the swing frame collapsed. Fig. 4 is a side elevation of the swing frame collapsed. Fig. 5 is a cross sectional view on the line. 55 Fig. 1. Fig. 6 is a cross sectional view on the line 66 Fig. 2. Fig. 7 is a cross sectional view on the line 77 Fig. 1. Fig. 8 is a cross sectional view on the line 88 Fig 2. 5?

Referring now to the drawings in which like characters of reference designate similar parts, the swing frame is shown to comprise four legs 10. each pair of legs on the same side of the frame being pivotally connected atthe upper ends to a side plate 11 by means of pivot pins 12. There are arcuate slots 13 formed in the side plate concentric with the pivot pins, these slots slidably receiving guide pins 14 carried by the legs whereby the legs may be rocked outwardly on their pivots to downwardly divergent relation or may be rocked inwardly on their pivots to downwardly convergent relation. The pair of front legs and also the pair of i'ea1"le'gsare connected by respective pairs of crossed links 15 and 16 pivotally connected at their crossing as shown at 17 the upper ends of the links being pivotally connected to the respective legs by pivot pins 18-and the lower ends of the links having longitudinal slots 19 through which pass guide pins 20 carried by the legs. These pairs of crossed links may be collapsed by pressing the side plates 11 toward each other whereby the front legs will be moved toward each other in parallelism as will also the rear legs and facilitate the frame being collapsed into a small'compact bundle for shipping or storing. By forcing the side plates 11 away from each other the crossed links are extended whereby the legs are forced bodily outwardly and caused to assume the usual divergent position. The swing seat 21 is provided on the sides with the usual swing arms 22 each of which is provided at the upper end with a hook 23 which is removably engaged in an opening 24 formed in the related side plate 11.

In operation suppose that the swing is in set up or operative position as shown in Figs. 1 and 2 and it is desired to collapse the swing for storing or shipping into the com- ,pact bundle shown in Figs. 3 and 4. The

arms 22 are bent toward each other at the upper ends and raised slightly until the hooks disengage from the side plates whereupon the seat may be bodily removed from the frame. The front and rear legs on each side of the frame are now rocked toward each other until they assume the downwardly convergent relation shown. The pair of front legs and the pair of rear legs are now moved toward each other by pressure upon the side plates until they assume the substantially parallel juxtaposed position shown. To set up the frame the above operation is reversed.

From the above description it will be seen that I have provided an extremely simple and effective collapsible swing which may be collapsed into a small compact bundle for storing and may be readily set up when desired without inserting any screws, bolts or similar devices.

1 WVhat' is claimed, is :v

In a swing, frame comprising a pair of front andrear legs, plates,-the legs of each pair having their upper ends pivotally connected to the plates, said plates having slots formed therein below the pivotal connection ed to the legs, and a seat removably asso- 10 with the legs, pins carried by the legs and ciated With the plates.

slidably engaged in the slots to limit the In testimony whereof, I aflix my signaswinging movement of the legs in opposite ture, in the presence of two witnesses.

-' directions, a pair of links for each pair of WILLIAM 0 BALL legs, said links being pivotally connected at their centers and having their upper ends Witnesses:

pivotally connected to the legs, and their EDWIN B. BALL, lower ends slidably and adjustably connect- CHARLES H. BARKMAN.
