[whim/TOR WILLIAM E. POTTER, OF ARMOURDALE, KANSAS.

SWING.

Specification of Letters Patent.

Patented Oct. 12, 1920.

Application filed April 29, 1920.v Serial No. 377,566.

To all w hom it may concern Be it known that I, VILLIAM E. POTTER, a citizen of the United States, residing at Armourdale, in the county of Wyandotte and State of Kansas, haveinvented a new and useful Improvementl in Swings, of which the following is a specification.

My invention relates to a swing, especially to a porch swing, and has for its object principally, to provide means whereby the oscillation of the swing is started and maintained by the foot pressure of the swinger without the violent bodilylexertion usually required; also,l for enabling the swing seat'to be extended for use as a couch.

It consists in features of novelty as hereinafter described and claimed,-reference being had to the accompanying drawing forming part of this specification, wherein,

Figure l, is a top plan view of -my improved swing, omitting the suspension ropes or chains and the operating cord forming part` of my invention, and showing the hinged foot rest forming part of the invenf tion, in the extended horizontal position; Fig. 2, a front elevation ofthe swing with the foot rest inclined upward Aabout itsv hinges; Fig. 3, an end or side elevation of the swing with the foot rest inclined upward as in Fig. 2; Figs. 4, and 5, transverse and horizontal sections to enlarged scale through parts of the deviceron lines 4, 4, and 5, 5, respectively, in Fig. 3; Fig. 6, a diagrammatic view of the swing corresponding to Fig. 3, suspended from a ceiling and at rest, or plumb.; Fig. 7 a similar view to Fig. 6, showing the swing when moved forward about its point of suspension according to my invention, and F ig.r 8, a corresponding view to Fig. 3 showing a modification of the device.

Like letters and numerals of reference denote like parts in all the figures. Referring to Figs. 1, 2, 8, 4, and 5, a represents the swing seat which in the present case is preferably mounted on a rectangularshaped frame b comprising a front longitudinal memberl, an opposite rear member 1, and two opposite transverse end or side members 2, the front and rear members 1, 1', preferably extending for a suitable distance beyond the end members 2, and to these extended portions of the members 1, l', are hitched the suspension ropes or chains c, c', at each end of the swing which converge therefrom to a single point of suspension c2 as shown in Figs. 6 and 7.

From each member 2 preferably depend a front leg 3, and a rear leg 3, whereby the swing when not in use as such, may be disconnected andplaced on the ground for use as a bench or seat.

At each end of the seat ais preferably hinged to the corresponding end member 2 of the frame I) an arm l which is normally in the raised position as shown, but which may if desired be folded downward and rest on the extended portions of the members l, 1', as shown by dotted lines in Figs. 1 and 2, so as to form -an extension of the seatl a for use as a couch. For lockingeach arm cl in its raised position (see Figs. 3 and 4) I may use a latch 4 which is pivoted at .one end to the back of the seat a and adapted to engage at its other end with a slotted bracket or keeper 4 fixed to the outer side ofthe arm c`Z- as shown; or other means may be used for this purpose.

Fixed to and between the front and rear legs 3, 3, preferably on their inside faces, at each end o-f the frame b, at 'a suitable distance beneath and parallel to the seat a, and to each other, are preferably two guide bars 5 between which is mounted the corresponding side edge portions of a rectangular-shaped framework e which is slidably adjustable in the guides 5 and may be locked in any desired position of its front edge relatively to the swing seat a, by a bolt 6 i which is passed through a block 7 fixed to, and spanning the space between the bars 5, and adapted to engage in either of a series of holes 8 which are formed in the said side edge portions of the framework e as seen in Figs. 3 and 4.

To the front edge of the slidable framework e and extending preferably the entire length thereof, is hinged a foot rest f which is upwardly inclinable at any desired angle relatively to the framework e and swing seat a, and to each end of the foot rest is pivoted a vertically arranged pulley g, while to the outside of each front leg 3 of the swing at a suitable distance below the Seat a is pivoted a pulley g', and to each rear leg 3', a pulley g2, which is preferably below the front pulley' g', the pulleys g, g', g2, being in the same vertical plane with each other.

To the ceiling at a suitable distance from the-foot rest the point of suspension of the swing at each end thereof by the front and rear ropes c, c respectively, is hitchedone end of a cord m (hereinafter termed operating cord) which passes thence under the front pulley g, thence over and under the rear pulley g2, and thence under and over the pulley g kof the other end of the operating cord x being hitched to an eye-bolt 9 fixed to the front part of the swing as seen in Figs. 6 and 7 In operation, assuming the parts to be in their normal operating position as shown in Fig. 6, when a person is seated on the swing seat (L and presses with the Vfoot against the foot rest f, the operating cord as will be shortened between its Vpoints of attachment to the swing and ceiling, vand the weight of the front portion of the swing, which is normally supported by the suspension rope c will be shifted to the operating cord .so that, the swing being now supported by the suspension rope c andV operating cord ai, its center of gravity will be midwaybetween the points of attachment of the rope c and cord to the ceiling, or forward of its original position, which will cause the swing to move downward andl forward into the position seen in Fig. 7 or thereabout. On removal of the foot pressurefiirom the rest f the swing will be returned by gravity to its original position and, by its momentum, rearwardlyvbeyond the latter, when on repeating the operation by renewing and releasing the foot pressure alternately, the oscillation of the swing will Y pulley pivoted to each end of the be increased and'its momentum maintained to any desired extent without undue exertion by the swinger.

Fig. 8 shows'my invention as applied to y a single board swing seat a without the Vunderframe b described and shown 1n Figs.

l, 2, and 3, the foot rest with the pulley g, and the pulleys g', g2, in this case being pivoted to L-irons or equivalent members, attached to the underside of the seat a as shown.

vrI claim:

l. `In a swing, a seat having a single point Ofsuspensionat each end, a foot rest hinged to the swing below the level of the seat, a said rest, a pulley pivoted to each end of the swing at the front and rear respectively thereof, and a cord hitched at one end to a point of sus pension adjacent to the first named point, the said cord passing thence around the said pulleys and hitched at-its other end to the swing. Y

2. In a swing, aV seat having a single point of suspensionat eachl end, a member adjustable beneath the seat, a foot rest hinged to the said member in advance, of, and below the levelof the seat, a pulley pivoted to each end of the said rest, a pulley pivoted to each end of` the swing atthe front andV rearrespectively thereof,gand a cord hitched at one end to a point of suspension adjacent tothe first named point, the said cord passing thence around the said. pulleys and hitched at its other end to the swing.
