To all whom t may concern:

Be it known that 1, JOHN M. MAYER, a citizen of the United States, and a resident of Kingston, in the county of Ulster and State of New York, have invented a new and Improved Lawn-Swing, of which the following is a' full, clear, and eXact description.

Among the principal objects which the present invention has in view are: to provide a structure of the character mentioned which may be closely folded; to provide a light frame; and to reduce the cost of construction of an apparatus of the character mentioned.

Drawings.

Figure 1 is a side view of a swing constructed and arranged in accordance with the present invention, the same being shown disposed as in service;

Fig. 2 is a side view of the same, being shown as folded and out of service;

Fig. 3 1s an end-view of the structure' in service and as seen in Fig. 1;

Fig. 4 is a detail View in perspective, showing the top of the frame `-and suspension bars thereof;

.Fig 5 is a detail view showing the con nection between the brace bars for holding in spaced relation the supporting frames of the swing structure.

Description.

As seen in the drawings, two supporting frames are employed,.each of the said frames having oppositely-disposed side struts 10. r1`he struts 10 are bolted to foot bars 11 and head bars 12. The bars 12 are slightly shorter than the bars 11, thereby providing a spread for the feet of the frames formed by the struts 10 and bars 11 and 12. The corners formed by the struts 10 and foot bars 11 are reinforced by braces 13.

Bolted to each of the head bars 12, are

20. The outer ends of the brackets 19'are pivotally connected by pins 21, with the seat backs 22. The backs 22 are held in positionv by the seats 18. To this end, the backs 22 rest against the said seats, which in turn are supported by cross cleats 23 extending between and rigidly connected with the brackets 19.

The struts 10 are held in spaced relation and inclined toward each other by the sills 24, on which the lower ends of the said struts rest, and to which they are rigidly secured by bracket arms 25. The upper ends of the struts are held in spaced relation by the pivotally united locking bars 26. The bars-26 are pivotally united by a bolt 27. Each of the bars 26 is pivoted by a bolt 28 on a strut 10.- The combined length of the bars 26 determines the spaced relation of the upper ends of the struts 10 and frames formed in part thereby.

The bars 26 have each a hook stop 29, each stop being arranged to engage the opposite bar to hold the two bars in stright-line arrangement. The straight-line disposition of the bars 26 is further maintained by the swinging links 30, which are permanently pivotally mounted on the bolts 31 in the struts 10 and are arranged for temporary engagement with the bolts 27.

The bars 26 are constructed as lightly as consistent with safety, and are reinforced by Vshaped braces 32. The braces 32 are permanently engaged by the bolts31, and are arranged for temporary engagement by means of bolts 33 and pins 34, with the bars `26 and struts 10. The V-shaped-braces as shown best in Fig. 1 of the drawings, form an extended base support for the rods 26 on the struts 10.

To assist in maintaining the parallel'relation of the falls 16, they are permanently connected by the cross braces 35, as best shown in Figs. 3 and 4 of the drawings.

When not in active use, the swing structure is collapsed and folded in the position substantially as shown in Fig. 2 of the drawings. In this figure, it will be seen that the struts 10 and the bracket arms 25 thereof, have been released from the sills 24, and the feet or supporting ends of the said struts are drawn together. The V-shaped braces 32 and the links 30 after being released from engagement with the bars 26, permit the breaking of the joint of the said bars by ,swinging on the pins 87 to the upright position shown in Fig. 2 of the drawings. This yarrangement of the; seats 18 permits the inward swing ofthe brackets'19 and the seatl backs 22 connected therewith, which thereafter rest against the seats 18; It will be seen that when thus arranged, the swing f structure may be folded within a small compass. j

It is equally obvious that when desired to place the swing in service relation, this is quickly and readily accomplished, it being necessary only to spread the lower extremities of the struts 10 until the bracket arms 25 are properly placed on the sills 24. Then by lowering the centers or the pivotal joint ofthe bars 26, the upper ends of the struts 10 are spread the desired distance.V 'As the bars 26 ,assume the horizontal or straightline position, the stops 29 operate to hold the same until the links 80 and the braces ,32 are properly adjusted and secured to the to straight line, the seat backs 22 may be swung to permit the lowering of the rear of the seats 18 so that the said seats may rest upon the cleats 23. The swing structure will then be found in service or active relation.

'The parallel arrangement of the falls 26 and the spaced relation of the seats 18, are maintained at the lower end by the platform 38, the cross bars 39 whereof are pivotally Copies of this patent may be obtained for attached at one end to one of the pivot bars 17.

While the braces 26 have been herein disclosed as a single bar extending between the oppositely disposed'struts, it should be understood that where desired, there may be a pair of the said braces at opposite sides of the said struts, or, in other words, two pairs of braces connecting each pair of struts. Also while the braces have been shown and described as breaking the joint thereof upward, they may be arranged to break the joint downward by depressing the center of the combined braces.

It is obvious that the sills 24 may be elongated to any desired extent. When the bracket arms 25 are rigidly secured to the said sills, it will be seen that any tendency of the frame to overturn is corrected.

Olams.

1. In a swing, the combination of two supporting frames, bars connecting the frames at opposite sides, each bar being formed of two sections. pivoted together and to the frames, means for locking the said bars in alinement, braces pivoted to each frame and detachably connected with the pivots of the bars, and V-shaped braces secured to the frames and detachably connected with the sections of said bars.

2. In a swing the combination of two supporting frames, bars connecting the frames at opposite sides, each bar being formed of two sections pivoted together and to the frames, a locking member mounted on the pivot of each bar and provided with a hook at each endengaging a section of the bar, braces having one end pivoted to the frames and their ends detachably engaging the pivots of said bars, and V-shaped braces secured to the frames and each detachably connected with a section of said bars.
