COLLAPSIBLE SWING.

Specification of Letters Patent.

Patented June 19, 1917.

Application filed August 11, 1915. Serial No. 44,942.

To all whom it may concern:

Be it known that I, HARRY C. SMITH, a citizen of the United States, ancl'resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Collapsible Swings; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention refers to swings, and it has for its general object to provide a simple, economical, durable, collapsible swing, the same being preferably built up from metallic parts.

Specific objects of my invention are:

To provide a pressed steel chair unit to be assembled in pairs that together form hingedly connected back and seat members.

To provide a U-shaped metallic leg unit, pairs of which are hingedly connected to form back and front sets of legs that constitute the chair supporting frame.

To provide means for bracing the leg and chair members capable of movement whereby the said parts may be folded flat when the device is to be transported.

I/Vith the above objects in view, the inven tion consists in certain peculiarities of construction and combination of parts, as set forth hereinafter with reference to the accompanying drawings and subsequently claimed.

In the drawings, Figure 1 represents a sectional elevation of a swing embodying the features of my invention, the section being indicated by line 11 of Fig. 2.

Fig. 2, is a front sectional elevation of the same, the section being indicated by line 2-2 of Fig. 1, and;

Fig. 3 is a detail sectional plan view of the chair seat, the section being indicated by line 33 of Fig. 1.

Referring by characters to the drawings,

1 and 1 represent duplicate U--shaped leg members, the lower stretches 2 of which leg members form supporting feet. The upper ends of the leg members are hingedly connected by a transverse supporting bar 3, the ends of which are reduced and upset to form pintles 3 whereby the legs are confined.

In constructing the swing, the apertured ends of swing straps 4 are inserted upon the bar 3 which is circular in cross These plates are cut away at intervals to lighten the same, and to present a pleasing design, and the longitudinal edges of said plates are folded over to form stiffening flanges 5 6 respectively which flanges project beyond the body of the plates at opposite ends to form hinged tongues 7, 7, the same being connected by pivot studs 8. The flanges 5 of the seat plate are hingedly con nected to the lower ends of the swing straps 4 by pivot studs 9. The swing straps are also connected to the flanges 6 of the back plate by arm straps 10 which arm straps are pivotally connected to the flanges and the straps by studs 10, 10".

In order to support the frame of the swing rigidly when the parts are extended, I provide fold-able brace straps 11, which brace straps are hingedly connected to one set of the legs by studs 12, and the opposite ends of the brace straps are provided with looking recesses 13, which are adapted to engage pins 12 that extend from the other set of said leg members. Thus, it will be seen from the foregoing description, that a swing is produced. that is composed entirely of metal, and which is of such simple construction that it can be cheaply manufactured, while, at the same time, stability is insured.

It will further be seen that when it is desired, the entire mechanism can be folded flatly by first swinging the brace straps upwardly, and thereafter closing the legs together. The chair member can then be folded by swinging the seat and back members toward each other upon the'pintle 8, whereby the arm straps 10 will swing downwardly upon the pintle 10 to permit the closing up of said members.

It is manifest that while I have shown the seat units arranged in connection with a collapsible single swing, I may without departing from the spirit of my invention, employ the said construction with any type of supporting frame other-than that shown.

I claim: A

As an article of manufacture, a collapsible swing comprising a pair of U-shaped supporting members, a plurality of seat sus pension links, a shaft pivotally passed through adjacent ends of the links and having its end portions reduced and pivotally passed through the end portions of the arms of said members, heads on the reduced ends of said shaft, means for holding the members at a relatively angular inclination means for holding the said links against lateral movement on the shaft and a seat carried by the lower portions of said links.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin, in the presence of two witnesses.

HARRY C. SMITH.

GEO. W. YOUNG, H. C. JENKINS.
