2 Claims.

This invention relates to an improved lawn swing, and one of its objects is to provide a swing construction which will be safe, light and port- .able, and extremely strong and dependable, and capable of supporting two persons for swinging.

- Another object of the invention is to provide a lawn swing with inclined upright supports, and a bar holding the upper ends of the uprights in spaced relation to each other by means of plates welded diagonally to the ends of the bar and bolted to the upper ends of the uprights.

., A further object of the invention is to provide a swing with opposing seats, each seat including an inclined back rest bolted to the vertical hanging bars which support the seats for swinging motion, and connected to the stationary supports of the lawn swing by self-centering hangers.

With the above and other objects in view the invention relates to certain new and useful constructions, combinations and arrangements of parts, clearly described in the following specification, and fully illustrated in the accompanying drawings, in which:

Fig. 1 is a side elevation.

': Fig. 2- is a front elevation, partly broken away. i Fig. 3 is a fragmentary elevation of the mounting for the main shaft or supporting bar.

Fig. 4 is a fragmentary side view thereof, partly in section. I,

Fig. 5 is a view partly in section and largely in elevation of the hanger for each of the vertical supports for the swing.

Fig. 6 is a fragmentary sectional view, taken on line 6--6 of Fig. 1, looking in the direction of the arrows.

Fig. 7 is an enlarged fragmentary sectional view thereof.

Fig. 8 is a fragmentary side view of the joint between the back rest of the seat and the lower end of the hanger bar for the swing.

Fig. 9 is a fragmentary plan View showing the truss connection between the companion supporting frames.

Referring to the drawings, which illustrate a practical embodiment of the invention, 5 designates one end supporting frame and 6 the companion end supporting frame, each frame being made in duplication of the other. One only will be described in detail.

Each frame consists of upright supporting bars I and 8, which are inclined upwardly so their upper ends will be closer together than their lower ends. The lower end portions of the upright bars I and B are connected to each other by the cross bar 9, and the end portion of this cross bar 9 is connected to the upright bar "I by means of the brace I0, and the other end portion of the horizontal tie bar 9 is connected by the brace II to the upright bar 8.

The upper end of the upright bar I is equipped with a metal plate I2, which is attached thereto by bolts I 3, and to this plate the end of the hanger shaft or bar I4 is connected, as by the weld I411. The plate I2 is welded to the end of the hanger bar or shaft I4 in diagonal relation thereto, so that the plate can be secured in the same inclined plane as the upright bar 1, while the shaft I 4 is held in an approximately true horizontal plane. The other end of the shaft I4 is welded to the plate I5, which is bolted to the upper end of the upright 8 by means of the bolts I6, and the plate I5 is connected to the shaft I4 in diagonal relation for the purpose explained with reference to plate I2.

A hanger shaft I! is welded at one end to the diagonal plate I2, and at the other end to a similar diagonal plate I9, and these plates are secured by bolts to the upper ends of the

frame uprights

7 and 8 of the frame 6. The two hanger shafts I4 and I1 are disposed in approximately the same horizontal plane.

On the hanger shaft I4 the upper ends of the hanger bars 20 and 2| are mounted by means of the strap metal U-shaped hangers 20a and ZIa, which form loops through which the shaft I 4 extends. The lower ends of the :hanger bars 20 and 2I are mounted on the lower cross shaft 22. On this shaft the ends of the

horizontal platform bars

23 and 24 of the swing platform, which includes the foot slats 25, are mounted for pivotal movement.

On the hanger shaft 11 the

hanger bars

25 and 21 are supported by the strap hangers, which are U-sh'aped. Each of these hangers is bolted directly to its hanger bar. The lower ends of the

hanger bars

26 and 21 carry the horizontal cross shaft 30. and this cross shaft pivotally supports the

platform side bars

23 and 24, so that the platform is held in an approximate horizontal plane. 7,

The hanger bars 20 and 2| support the seat back bars 3|, the lower ends of which are cut diagonally, as shown in Fig. 8, and secured by the cross bolts 32 to the bars. On the seat back bars 3| back rest slat-s 33 are mounted, by means of the connecting

frame cross bars

34 and 35. The entire seat back rest thus provided is supported in upwardly and outwardly inclined relation to the hanger bars.

Side seat supporting bars 36 are bolted to the angular or inclined relation to the platform and seats. The

hanger bars

26 and 21 similarly support the seat 39, and the seat back rest 40.

The upper ends of the hanger bars 20 and 2| are rigidly spaced apart by the bar 4|, and the upper ends of the

hanger bars

26 and 21 are rigidly spaced apart by means Of a similar spacing bar.

The frame 5 is connected to the frame 6 on each side by means of the truss work, comprising the

brace bars

42 and 43, which cross each other .at' 44 and are secured at the points of intersection to each other by the bolt 44a. One end of each brace bar is secured to each upright frame. This truss connection rigidly holds the two upright supporting frames inclined upwardly toward each other, as shown in Fig. 1, thus adding greatly to the stability of the swing and to its satisfactory operation.

The ends of the cross shafts may be equipped with cotter pins 45, and with washers 45a, so that they may be assembled with little mechanical skill, or taken down for storage or shipment. A single bolt connects each U-shaped strap hanger to its hanger bar, so that a slight lateral swinging motion may be permitted.

All of the frame parts of the stationary supports and the swing are constructed with light wood or other suitable material, and the connection between the parts thereof afford great rigidity and strength to the stationary supporting frames, and parallel swinging motion for the two seats.

The improved swing will improve the appearance of any lawn in which it is installed, and can be easily taken apart when the outdoor use of the swing is no longer practical.

Having described the invention, it is understood that various changes in the details of construction, their connection and combination, may be varied in carrying out the invention, as defined by the claims hereof.

Having described the invention, I claim as new:

1. A swing construction, comprising a pair of stationary frames, crosswise disposed brace bars connecting the upper ends of the frames, each frame including upright supporting bars, a hanger shaft disposed between the upper ends of the upright bars of each frame, the extremities of said shaft being formed with faces inclined to the axis of the shaft and diagonal plates welded to the extremities of said hanger shaft and bolted to the upper ends of the upright bars of each frame, hanger bars supported for swinging movement on each hanger shaft, a platform pivotally connecting the lower ends of the hanger bars to each other, and seats and seat back rests carried by each set of hanger bars above said platform.

2. A swing construction, comprising a pair of stationary frames, each frame including upright members disposed in inclined relation to each other, a truss connecting the upper ends of the frames to each other on each side thereof, a cross shaft disposed between the uprights of each frame, the extremities of said shaft being formed with faces inclined to the axis of the shaft and diagonal plates welded to the extremities of the cross shaft and secured to the uprights of the frames, hanger bars suspended on the cross shafts, a platform connected to the lower-- ends of the hanger bars, seats and seat back rests carried by the hanger bars, and a'spacer bar dis posed between the upper ends of the hanger bars.
