ATTORNEYS.

United States APatent AOv This invention relates to swing construction, and

aims to improve generally the constructionas shown'in'` my Patents Numbers 2,394,913, and 2,413,232.

An important object of the invention is to provide a swing embodying a frame so constructed that a person occupying the seat of the swing would be guarded against falling forwardly from the seat while the swing is in motion.

Another important object of the invention is to provide a frame structure which will permit of free movement of the arms of the occupant of the swing in operating the swing, and at the same time provide means for maintaining the occupant of the swing centered on the seat.

A still further object of the invention is to provide an improved swing hanger which is so constructed and arranged that the hanger may be securely fastened to a supporting rod in such a way as to grip the supporting rod and hold the bearing securely in place.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawing:

Figure l is a4 front elevational view of a swing constructed in accordance with the invention.

Fig. 2 is a side elevational View thereof.

Fig. 3 is a sectional view taken on line 3 3 of Fig. 2.

Fig. 4 is a sectional View taken on line 4--4 of Fig. 1.

Fig. 5 is a sectional View taken on line 5-5 of Fig. 2.

Fig. 6 is a fragmental sectional view illustrating the manner of connecting the uppermost cross rod of the swing, to the side rails thereof.

Fig. 7 is a sectional view through a modified form of bearing hanger.

Referring to the drawing in detail, the swing embodies side bars 5 which are held in spaced relation with respect to each other by means of the brace bars 6 which are preferably welded to the bars 5, and cross each other at a point intermediate the ends thereof.

Connecting the upper ends of the bars 5, is a horizontal rod 7 on which a bearing 8 is positioned, there being provided a grease fitting 9 on the bearing 8, through which grease is forced for lubricating the tubular bearing 8.

A horizontal rod 7 is held stationary with the side bars 5, by welding as at 10.

The reference character 11 indicates the bearing hanger which embodies a pair of curved arms constructed to fit around a swing supporting rod 12, the lower ends of the arms of the bearing hanger being curved in opposite directions as at 13 to securely grip the bearing 8, as better shown by Fig. 4 of the drawing.

The arms of the bearing hanger 11 are extended latice erally providing ears 14 which ears are apertured to receive the bolt 15 which bolt is provided with a nut 16 for drawing the ears 14 towards each other to grip the supporting rod 12.

It will of course be understood that these bearing hangers are arranged in pairs so that the swing supported thereby will be supported for a true swinging movement.

The lower ends of the side bars 5 are supplied with sockets 16 which are welded to the lower ends of said side bars, the sockets being of diameters to recevie the upper ends 17 of the forwardly extended operating handles 18.

The sockets 16 have a plurality of openings 19 that are adapted to register with the openings of the upper ends 17 of the handles 18, for the reception of the bolts 18 holding the handle sections in their positions of vertical adjustment on the bars 5.

The swing also includes a lower frame embodying a pair of front bars 19 which have their upper ends welded to the bearing 21 on which the tubular bearing 21 is mounted, the connecting rod 20 being welded to the handles 18, at a point where the forwardly projecting ends of the handles merge into the vertical upper ends 17.

These front bars 19 as better shown in Fig. 1 of the drawing, curve inwardly at 22, the extremities thereof extending downwardly at 23, where they are secured tobether, the bars 19 extending laterally at 24 and rearwardly at 25 providing a rectangular seat portion in which the seat 26 is fitted. The rear bars extend upwardly from the lower space portion of the frame and rise in parallel spaced relation with respect to each other as at 27, the upper ends of the bars being inclined upwardly and forwardly at 28, where they connect with the tubular bearing 21. The portions 27 of the frame are braced by a horizontal brace rod 29 which extends between the upwardly extended portions 27 of the frame, as better shown by Fig. 1 of the drawing.

In order that the tubular bearing 21 will be adequately lubricated, a grease fitting 30 is mounted on the bearing 21, through which grease is supplied to the bearing.

In the form of the invention as shown by Fig. 7 of the drawings, a modified form of bearing hanger is illustrated, and with this form of hanger the bearing 31 on which the swing operates, embodies a pair of arms 32 which are so curved that they provide an elongated loop for fitting around a pair of supporting tubes such as indicated at 33.

In this form of the invention the bracket arms extend laterally at 33' providing ears which are also apertured to accommodate the bolt 34 for moving the sections of the bearing bracket into gripping relation with the tubular support 33.

From the foregoing it will be seen that due to the construction shown and described, I have provided a swing embodying an upper hanger section and a lower swing frame pivotally connected therewith, the upper hanger section embodying forwardly projecting operating handles which are gripped by the occupant of the swing and pulled causing the swing to move forwardly and rearwardly in the usual and well known manner.

It will also be seen that because of the construction of the seat and frame, the occupant must straddle the downwardly extended portions 23 of the frame which will of course prevent the occupant from sliding forwardly from the seat in operating the swing.

lt will also be seen that the occupant of the swing will have free swinging movement of his arms in manipulating the swing, and the body of the occupant of the swing will be disposed directly behind the front bars 19 so that the head of the occupant may swing between the front bars 19 while the occupant is operating the swing.

lt will also be noted that due to the construction of the swing it may be readily and easily dismantled for storing or transportation, requiring but small space when dismantled.

l. A swing embodying an upper swing member including spaced side bars, socket members secured to the lower ends of said side bars, operating handles having one of their respective ends secured within said socket members, a lower section including front and rear bars, pivotally connected with said operating handles, a seat secured between said front and rear bars, said front and rear bars being secured to said seat adjacent to the longitudinal center line of said seat providing a guard for a person occupying the seat, and hangers including bearings on which said swing hangs.

2. A swing embodying an upper swing section, operating handles extending downwardly and forwardly from said upper swing section, a lower swing frame including vertical front bars, connected with said upper swing section, rear bars spaced from said front bars, the lower ends of said rear bars extending forwardly and then inwardly providing a seat frame, said front bars being connected to said seat frame at a point intermediate the sides of said seat frame, and a seat positioned in said seat frame.
