SWING Fil ed Sept. 12, 1938 IN VENTOR.

ATTORNEY.

Patented May 14, 1940 UNITED sures rater rris 2 Claims.

This invention relates to swings in the nature ofthose adapted to be suspended from an overhead supporting element and the primary object of the invention is to provide a swing of this character wherein is included unique andncvel means for propelling the same through the medium of structure which may intermittently and periodically move the load center so. that the tendency of the swing to oscillate about the points of suspension occurs as the user desires.

One of the important aims of this invention is the provisionof a swing of the aforementioned character wherein is included specially created bifurcated arms that are attached to suspension members in a novel manner, so that the desired action of the swing occurs when exerting a minimum amount of effort to the end that the user may rest and at the same time swing. to and fro Without the exertion of tiring effort.

Another object of this invention is to provide a swing which has a removable, uniquely retained fabric strip that forms a major part of the seat portion and back portion of the swing, which strip may be quickly and conveniently removed from the frame of the swing. V

A yet further aim of this invention is to provide a swing structure of the aforementioned character wherein is provided unique means'ior maintaining the fabric strip thereof in the operative position and at a degree of tautness satisfactory to the user.

Minor objects of the invention will appear during the course of the following specification, referri'ng to the accompanying drawing wherein:

.Figure 1 is a perspective view of a swing made in accordance with the present invention.

Fig. 2 is aside elevation of the same.

Fig. 3 is an enlarged fragmentary detailed sectional view taken on line IIIIII of Fig. 2; and,

Fig. 4 is a similar view taken along line IV-IV of Fig. 2.

Swings of a character similar to that embodying the present invention, have been designed and constructed by me and are disclosed in my prior United States Letters Patent Nos. 1,783,502, issued Dec. 2, 1930, and 2,048,110, issued July 21, 1936. It has been found however, that the results obtained through the relatively simple structure, disclosed herein, are superior to those obtainable through the morecomplicated devices previously known and therefore, the rugged, durable and simply constructed swings contemplated by this invention that operate more freely and with less effort, are preferred.

In the illustrated embodiment of the swing there is provided a frame constructed of wood or 7 similar material which comprises a front rail 6, a pair of side rails 8, and a backrail it, all of which combine to form the seat portion of the swing.

Extending upwardly from the back edge of the seat'portion, is a back portion that comprises a pair of substantially vertical side rails l2,

joined at their upper free ends by a top rail l4.

A pair of arms it are provided, one of which is disposed along each side of the seat portion thereabove. Each arm l5 hasan outwardly extending bifurcated length It? beneath which is disposed a swingable foot rest 20. The inwardly directed notch 22 which is provided in the outwardly extended length of each arm Iii, receives the stiff link 24 that forms a part of the front suspension members 2%. Rear suspension members 23 are in the nature of elongated links and the irontsuspension members 25 are likewise flexible members, such .as cables or link chains.

The rear ends of arms. I6 are secured to side rails 52 through the medium of bolts 3% or the like, to which the ends of rear suspension members 28 are attached as shown in Fig. 4. The best mode of attachment is found to be an eye 32 which circumscribes bolt 30 with a leather washer or the like 3 3 interposed between eye 32 and bolt 30 to insure noiseless operation. Relatively short standards 36 through which pass tie-bolts 38, support the forward end of arms l6 in spaced relation to said rails 83.

Each link section 24 is provided with a crosspin 46 that underlies the bifurcated link of the respectivearms l6 and a loop 42 on each side of link section 24 journals the ends of cross-pin fill to preclude displacement and to further insure noiseless operation at this point.

Ashield 44 is loosely and slidably carried by link section 2 to overlie notch 22 in arm I6. Thus, when link section 241 is fulcrumed about cross-pin 40, the danger of pinching the fingers is eliminated.

' Side rails. 8 of the seat portion each has a series of holes 48 and a rod 48 has its ends journalled in selected opposed holes 46 to support one end of the fabric strip 59 which closes the space between rails 8 of the seat portion and between rails 12 of the back portion of the swing. v

Rails I2 of the back portion each has an opening 52 arranged in opposed relation so as to receive rod 54 and opposed notches 56 formed in rails l2 receive bridging rod 58 that lies against Lil the face of fabric strip 56 when the strip is in normal operative position.

Fabric strip has a tube 60 formed across the normally forward end thereof and a tube 62 formed along the opposite end. Tube 50 receives rod 48 after the forward marginal edge of strip hole 46, rod 58 may be forced into place so that strip 50 is drawn especially taut and a well stretched surface is presented.

Rod 54 and top rail I 4 are ofiset so that an inclined portion 64 is created to be used as a head rest.

An exceptionally snug fit may be established when assembling the swing because braces 66 preclude relative movement between the seat portion and the back portion of the swing where they are joined together by bolts 68 that interconnect the overlapped ends of rails 8 and i2. Foot restZO may be moved toward and from the seat portion by adjusting set screws 10.

During the operation of the swing, links 24 are fulcrumed about the axes of opposed. cross-pins 40 so that suspension members 26 are moved toward and from the center of gravity at the ends thereof which are attached to the upper extremities of links 24. Thus, the entire swing assembly and occupant is moved to and fro beneath the points of attachment between suspension members 26 and 28 and the support thereof.

It is necessary in the efficient operation of the swing embodying this invention, that link sections 24 be in longitudinal alignment with their associated suspension members 26. The minimum number of bearing surfaces are presented and merely moving foot rest 20 to andfro by a slight and untiring action of the foot, will sufiice to impart movement to the swing.

It is obvious to one skilled in the art that many modifications and structural differences might be made without departing from the spirit of the invention or scope of the appended claims.

' there being a suspension member passing through the bifurcatedlength of each arm' respectively and into engagement with said foot rest, the'portions of said suspension members intersecting the arms and extending to the foot rest being in the nature of a stiff link for the purpose specified, each of said 1inks having a cross-pin passing therethrough to underlie the bifurcated length of the associated arm, each arm having loops of leather or the like circumscribing the cross-pin on each side of thesaid link whereby the links are pivotally joined to the arms and the suspension members having said links therein support the weight of a portion'of the swing.

2. A swing of the character described comprising a frame having a seat portion; an arm on the frame disposed along each side of the seat portion. thereabove and each having a bifurcated length extending outwardly beyond the seat portion; a foot rest forwardly of and below the seat portion beneath the bifurcated lengths of said arms; and suspension members for the swing, there being, a suspension member passing through the bifurcated length of each arm respectively and into engagement with saidfoot rest, the portions of said suspension members intersecting the arms and extending to the foot rest being in the nature of a stiff link for the purpose specified, each of said 1inks having a shield slidably carried thereon to overlie the b-icurcated portion of the associated arm for the purpose specified said links being pivctally joined to the arms at their zones of intersection.
