SWING.

SPECIFICATION forming part of Letters Patent No. 556,981, dated March 24, 1896.

Application filed August 10, 1895. Serial No. 558,805. (N0 model.) 7

T0 in whom it may concern.-

Be it known that I,WALTER HOWARD, a citizen of the United States, and a resident of IVashington, in the District of Columbia, have invented certain new and useful Improvements in Swings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

In the drawings, Figure 1 is a side elevation of the swing and of a supporting-frame therefor. Fig. 2 is a side elevation of the swing partially in section, with the suspension-bars broken off, a canopy being shown, while the guards areremoved. Fig. 2 is a detail perspective view of a canopy-frame for the seat. Fig. 3'is a detail sectional view showing the manner in which the end portions of the swing-bottom are supported. Fig. i is a detail sectional view showing one of the bearings for the foot-power slide. Fig. 5 is .a perspective view showing a portion of the foot-power slide and its connections with the power-levers. Fig. 6 is a detail view of means for adjusting the canopy-frame. Fig. 7 is a detail view, partially in section, showing the fulcrum for one of the power-levers and its connection with the swing-frame. Fig. Sis a detail view showing how the swing may be suspended from the ceiling or other overhead support.

The object of this invention is mainly to provide a swing capable of being easily and conveniently propelled by the riders by either hand or foot power, or by a combination of both; also, to provide an improved construction and arrangement of the seats with means .whereby they may be adjusted both angupended.

the back, and facing each other.

B B designate the suspension-bars, there being four, two upon each side. These bars are pivoted to the frame A at their upper ends, and their lower end portions are pivoted upon the end portions of transverse rods 0 of the swing-frame. These rods extend entirely across the swing, one near each enc thereof.

D D (see Fig. 3) are the longitudinal lower side bars of the swing, there being two of these bars upon each side, separated from each other by a short interval, and parallel. Y

E is the bottom of the swing, which is suspended from the bars D D by the clips F at each end portion (see Fig. 3) and by the bolts F (see Fig. 7) at the central portion.

Other suitable means may be employed for securing the bottom portion in place, but they should preferably be of such character that said bottom portion can readily be detached. Said portion preferably consists of a series of parallel longitudinal slats which are secured to transverse cleats or bars 6.

G G designate the two seats, which extend across the swing, one at the front and one at Said seats consist each of the two rear legs, g, which are extended up to form the side rails for the backs G the forward legs, g, the seat portions G and the arms G The forward legs, g, of each seat are pivoted between the rails D D, and the rear legs, g, enter between said rails and are provided with studs or bolts g which slide upon the upper edges of said rails as the seats are adjusted. The connection of these legs with the siderails is made adjustable, as illustrated, by the series of holes, in order to adapt the seats to children and to grown persons of different height. The seat and arm portions are pivotally connected to the legs to permit a parallel movement of the parts in adjusting.

In the drawings, Fig. 2, I have shown the seat G in reclining position and have also shown it as being provided with a shade or canopy. This shade or canopy consists of a frame, such as shown in detail in Fig. 2, having a number of bail-shaped pieces H, the end portions of whose vertical lateral arms are adjustably and pivotally connected to the side which is secured to the side bars D.

In order to facilitate the adjustment of the canopy as the seat is given different adjustments, the rear piece H is provided at each end with a sector-plate H, which is pivoted to the back at 7L and is provided along its curved edge with a series of apertures 71., any one of which is designed to be engaged by a pin which also engages an aperture in the side rail of the back. By means of this device'and the adjustable connections of the other pieces H the canopy can be adjusted forward and back independently of the adjustment of the seats. Both seat-s may be provided with a like canopy, if desired, or it may be omitted entirely, as when the swing is indoors or under cover. To secure the seats in their desired adjustments, each is provided with a notch-bar I, the notches of which are designed to engage a stud on an arm I of the frame.

J designates side bars, there being two of these bars upon each side.

K designates transverse hand-bars, two for each seat, which are suspended across the swing by means of ropes J K the former of which connect to an upper bar J 2 and the latter to the respective bars J.

L designates vertical power-levers, two of which are provided upon each side of the swing. Each of these levers is fulcrumed intermediately of its ends at Z to an arm Z, (See Fig. 7.)

M designates the foot-power slide (see Fig. 5) which extends transversely across the central portion of the swing upon the bottom thereof. This frame preferably consists of a series of slats, which afford purchase for the feet, and which are secured to end cleats m. Said slide is mounted upon antifriction-rollers N, (see Fig. 4,) which run back and forth under pressure of the feet on tracks N secured to the upper faces of the lateral slats of the bottom E.

P are ropes or the like, one end of each of which is connected to one corner portion of the slide-frame, and the other end of the lower arm of that lever upon the same side of the swing which is most distant. (See Fig. 5.)

The upper arm of each lever L is fast to one of the bars J.

It will be observed from the manner in which the swing is suspended by the bars 0 that it will oscillate in a horizontal plane with a rising and falling or parallel movement, as distinguished from a movement in the arc of the circle described by the suspension-bars, and that any leverage obtained on the said bars will cause the swing to oscillate. This leverage is obtained by hand-power through the bars K and J, and byfoot-power through the slide -frame M, the connections P, the power-levers L, and the bars J. The best re sults are obtained by using both hand and foot power in combination, but either may be used alone.

For indoor use the frame A may be dispensed with and the swing be suspended from the ceiling or other overhead support, as indicated in Fig. 8.

B, Fig. 1, are lateral wire guards, which may be buttoned or otherwise detachably secured upon each side of the swing.

It will be observed that the swing can be readily taken to pieces and the parts be assembled in compact form for shipment or storage.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a swing, the combination of the pivoted suspension-bars, the swing-frame pivoted to the lower end portions of the said bars, the upper side bars connected to the suspension-bars and to the swing-frame and the suspended hand-bars connected to the said side bars transversely across the swing in front of the seats, substantially as specified.
