Patented July 1, 1952 ENT OFFICE OCCUPANT PROPELLED SWING Charles E. Petersen and Alfred C. Petersen, Logan, Utah Application November 24, 1950, Serial No. 197,397

3 3 Claims. (01. 155-455) This invention relates to swings for children of the type wherein a seat is suspended in an A- frame structure, and in particular a swing having a seat suspended by rods at the sides with the rods depending from a horizontally disposed shaft supported by A-frames at the sides, and in which a lever, pull cord, and spring combination is provided whereby an occupant of the seat propels the swing through the pull cord.

The purpose of this invention is to provide an improved operating structure whereby the occupant of a seat in a swing may efficiently propel or actuate the swing.

Various devices have been provided to facilitate operating a swing by an occupant thereof but where a direct pull on a cable over a pulley is provided the force required to operate the swing is excessive so that swings of this type have been discarded. With this thought in mind this invention contemplates a lever and spring assembly wherein a pull cord operates a lever which is connected to the swing structure through a, spring whereby the direct pull of a cable against the swing structure is relieved.

The object of this invention is, therefore, to provide means for connecting a pull cord to a swing suspended in a frame whereby an actuating force is applied through resilient means.

Another object of the invention is to provide an improved operating assembly for self propelled swings, particularly adapted for children whereby a comparatively small child may propel the swing.

A further object of the invention is to provide an improved propelling structure for swings for children and the like which makes it possible to provide a self propelled swing that is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a seat suspended by a rod from a shaft supported in the upper ends of spaced A-frames with a lever pivotally mounted in a brace extended forwardly of the frames and connected to the swing suspending bars by a spring and also provided with a pull cord positioned within easy reach of an occupant of the seat of the swing.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings wherein:

Figure 1 is a perspective view illustrating the general design of the swing and the arrangement of the parts thereof.

Figure 2 is a detail showing a longitudinal section through the upper part of the swing illustrating the lever and spring assembly.

Referring now to the drawings wherein like reference characters denote corresponding parts the improved swing operating mechanism of this invention includes a seat in suspended by bars H and [2 from a shaft I3 with the shaft supported by A-frames having upwardly extended members l4 and I5 at one side and I6 and [1 at the other, and with the swing actuated by a lever l8, one end of which is connected to the rods H and I2 through a spring [9, and the other end of which is provided with a pull cord 20 having buttons or balls 2| positioned in spaced relation thereon.

In the design shown the seat [0 is provided with end panels 22 and 23, a back 24 and a foot rest 25 which is supported by braces 25 and 21.

The supporting rods H and I2 are secured by screws 28 to the end panels and the seat is retained in operative position in relation to the bars by braces 29 and 30. A safety strap 3| may be provided across the front of the seat with the ends mounted on the rods II and I2.

The upper ends of the rods I I and I2 are connected to the shaft l3 by hinges 32 and 33 and the shaft is suspended in the upper ends of the guide bars of the A-frames.

The lower ends of the bars or members 14 and it are connected by a cross bar 34 and a similar bar 35 connects the lower ends of the bars or members l5 and IT. The members I4 and [6 are also connected by a cross brace 36 and a similar brace 31 connects the members It and I1.

The lever is is pivotally mounted by a pin 38 on and between arms 39 and 40 extended outwardly from a cross bar 4| that is supported by outwardly extended

rails

42 and 43, as shown particularly in Fig. 2. The rail 42 is secured to the bars l4 and [5 of the A-frame at one side by

bolts

44 and 45 and the rail 43 is similarly secured to the bars I6 and I1 by bolts 45 and 4?.

The pull cord 20 is attached through a loop 48 to an eye 49 in the outer end of the lever I8 and the wood balls 2! are supported in spaced relation thereon by knots 50 or other suitable means.

The opposite end of the lever 18 is connected to a loop 5| of the spring [9 by a link 52 in an eye 53 and the opposite end of the spring is connected to a cross bar 54 through an eye 55 also as shown in Fig. 2. The bar 54 is supported by the rods II and I2 through hubs 5B and 51 on the ends thereof and the hubs may be provided with set screws 58.

With the parts arranged in this manner a child positioned in the seat I, by pulling on the pull cord 20 may exert a forward pulling force on the seat through the rods II and I2 and with the swing traveling back with a pendulum action the seat may again be drawn forwardly whereby the action of the swing may be increased to substantially any swinging action desired.

It will be understood that modifications may be made in the design and arrangement of the parts without departing from the spirit of the invention.

What is claimed .is:

1. An occupant propelled swing comprising a supporting frame structure, a seat suspended by rods in said frame structure, a lever pivotally mounted on the upper part of the frame structure, a pull cord suspended from the outer end of the lever, and means resiiiently connecting the opposite end of the lever to the said seat suspending rods.

2. An occupant propelled swing comprising a supporting frame structure, a seat suspended'hy rods in said frame structure, said frame having an extension extended forwardly thereof, a lever pivotal-1y mounted on the said extension, a pull cord suspendedfrom the outer end of the lever, and means resiliently connecting the opposite end of the lever to the said seat suspending red.

3. In a swing, the combination of which comprises a pair of spaced A-frames providing a supporting structure, a horizontally disposed shaft supported in the upper ends of the A-frames, a swing seat suspended from the shaft by spaced rods, a forwardly extended supporting element positioned in the upper part of the structure and supported by the iA-tframes, a lever pivotally mounted on the forwardly extended element, a pull cord depending from one end of the lever, and spring means connecting the opposite end ,of the lever to the seat suspending rods.
