JOSEPH S. BOHATKA, OF CHICAGO, ILLINOIS.

SWING.

Specification of Letters Patent.

Patented May21, 1912.

Application filed March 1, 1912. Serial No. 680,796.

To all whom it'may concern:

Be it known that I, J osnrrr S. BOI-IA'LKA, a citizen of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Swings, of which the following is a specification, reference being had to the accompanying drawing.

My invent-ion relates to swings of the class adapted to be supported between door-posts or other oppositely-disposed uprights, the swing and its supports being adapted to be entirely removed whenever desired.

It is the object of the invention to provide removable supporting means for swings of this type which will be held securely in place whenever it is in use and which may be readily removed and as readily placed in position.

It is a further object of my invention to provide supporting means of this sort which may be folded compactly for storing when not in use.

It is a further object of this invention to improve swings of this type in sundry details hereinafter pointed out.

The means by which I have accomplished these objects are illustrated in the accompanying drawing and hereinafter specifically described.

That which I believe to be new is set forth in the claims.

The drawing is a view of a device embodying my improvements in position in a door-way, one of the pivoted bearing shoes being shown partly in section.

Referring to the drawing, 10 11 indicate door-posts, between which the supporting device is positioned.

1213-1 115 indicate levers, preferably in the form of metal bars, all mounted upon a suitable pivot-pin 16 so as to be capable of swinging relative to each other.

17 indicates shoes of any suitable type pivotally mounted upon the outer ends of the levers, each of the shoes in the construction shown being provided with a facing 18 of rubber or other suitable material.

19 indicates a spring tending to draw toward each other the levers l b-15, and 20 indicates a spring tending to draw toward each other the lever 1213.

21 indicates a cord or rope passing loosely through an opening in the short arm of the lever 13 and secured to the short arm of the lever 12 by means of clips or in any other suitable manner.

22 indicates a cord or rope passing loosely through an opening in the short arm of the lever 15 and secured to the short arm of the lever 14 by means of clips or in any other siutable manner.

23 indicates a clip of any suitable type carried by the lever 13 through which the rope 22 passes, and 24 indicates a similar clip carried by the lever 15 for the rope 21.

25 indicates a swing of any suitable type suspended from the ropes 2122.

.As will be readily understood, when the supporting device is placed in position between two oppositely-disposed uprights, the shoes 17 bear directly upon such uprights, the springs 1920 tending to force the levers at each side toward each other and consequently tending to force the shoes 17 at one side farther laterally from the shoes 17 at the other side. The force of the springs 19-20 exerted in this manner is suflicient to hold the device in position, the rubber facings of the shoes 17 enabling such shoes to effect a secure hold upon the door-posts. l/vhenever, with the parts in the positions shown, a child places its weight in the swing, the downward pull on the ropes 21-22 tends to draw the levers together at both sides, thus holding the supporting device firmly in position between the uprights.

W'henever it is desired to put the swing aside for the time being, this can be accomplished readily by merely forcing the levers apart at either side against the action of the springs 1920, when the supporting device can be folded together into a compact bundle and hidden away in any convenient place until it is wanted again.

It will be understood, of course, that my improved swing support may be used in door-ways of various widths, the springs 19-20 permitting the spreading of the levers apart to fit door-ways narrower than that shown in the drawing, and such springs serving to draw the levers closer together at the sides to fit door-ways wider than that shown.

What I claim as my invention and desire to secure by Letters Patent is,

1. In a swing support, the combination of four levers pivotally mounted relative to each other, two of which levers extend in one direction and two of which extend in the opposite direction to engage oppositely-disposed uprights, and a rope at each side connecting the short arms of said levers whereby a downward pull upon said ropes tends to draw the levers together at each side.

2. In a swing support, the combination of four levers pivotally mounted on a horizontal axis, the longer arm of each of which levers bears upon one of two oppositely-disposed uprights, and a rope at each side connected to the lower short arm at that side and passing through a suitable opening in the upper short arm at that side, whereby a downward pull upon said ropes tends to draw the levers at each side together.

3. In a swing support, the combination of four levers pivotally mounted relative to each other, shoes pivotally mounted on the arms of two of said levers extending in one direction, shoes pivotally mounted on the arms of the other two of said levers extending in the opposite direction whereby said shoes are adapted to bear upon oppositelydisposed uprights, springs connecting said levers tending to draw together the shoes at each side, and a rope at each side connecting the short arms of said levers whereby a downward pull upon said ropes tends to draw the lovers together at each side.
