Application filed May 19. 1903- Serial No. 157,881. (No model.)

To all whom it may concern:

Be it known that I, ALVAH A. HOFFMAN, a citizen of the United States, residing at Pleasantville, in the county of Venango and State.

of Pennsylvania, have invented a new and useful Porch-Swing; and I do hereby declare the following to bea full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same.

The invention relates to a porch-swing, and

has for its object toimprove the construction of swings and to provide a simple, inexpen i sive, and efficient one designed particularly for use on porchesand similar places and adapted to be readilyoperated by either an" adult or child.

A further object of the invention is to pro vide a swing of this character of great strength i a detail view illustrating the manner of.

mounting the actuating-lever.

Referring to the drawings, 1 designates a chair, which may be constructed of any desired size and of any suitable material and which is preferably provided with central and side pieces 2 and 3, each constructed of a single piece of material, as shown. The central and side pieces 2 and 3 are connected by transverse slat-s 4, and the chair is provided at opposite sides with arms 5, connected at theirrear ends with the back of the chair and supported at their front portions by upright pieces6, secured to the front portion of the chair at opposite sides thereof; but the arms may be mounted in any other desired manner, and the foot portion 7 of the chair is supported by braces 8. The braces 8 extend from the foot portion to the front ends of the arms. The chair issuspended from the top clearly shown in Fig. 1.

the foot of a person.

of the porch or other suitable support by suspension-ropes 9, secured at their lower ends to ears 10 of attachment-plates 11 by snap-hooks 12; but any other form of suspension device,

such as a rod or bar, may be employed, as

will be readily understood. The attachmentchair near its upperend and havingits upper end 15 bent out-ward and extended toa point in advance of the rear suspensiou rope, as The lower arm of the lever extends downward through a horizoutalguide 16 and depends below'the seat of the chair, to which the guideis secured.

The guide is secured to the seat at one side thereof and it extends rearward therefrom and it is adapted to maintain the lever plumb to prevent the said lever from twisting and becoming disengaged from the rope. The lower end of the lever isconnected bya link or bar 17 to the rear arm of a bell-crank lever 18, which is fulcrumed at its angle 19 in an upright guide 20. The upright guide, which supports the lever 18, is mounted on-the front portion of the chair above the foot-rest thereof, andthe front armof the-bell-crank lever is provided witha-lateral extension or footpiece 21,.whih is arranged to be engaged by When the foot-piece is depressed, the bell-crank lever is oscillated and the upper arm of the actuating-lever is swung rearward into engagement with the rear suspension-rope, thereby actuating the swing and producing a gentle easy motion of the same. The foot-piece of the bell-crank lever is arranged at one side of the chair, out of the way, and is not liable to catch the clothing or foot of a person using the swing.

What I claim is' i, l

l. The combination with a chair, and means for suspending the same from a suitable support of an upright lever, f ulcrumed between its ends on the chair at the back thereofQand engaging the said means and a foot-lever fulcrumed on the chair at the front portion thereof and connected with the upright lever, substantially as described.

2. The combination of a chair, provided at I link connecting the other arm of the bellthe back with a horizontal guide and having an upright guide at thetfront, means for suspending the chair from a suitable support, an upright lever fulcruined between its ends on the back of the chair, with its upper arm engaging the said means and its lower arm arranged in said horizontal guide, a bellcrank lever fulcrum'ed at its angle in the upright guide, and provided at one arm with a lateral extension forming a foot-piece, and a crank lever with thelower arm of the upright lever, substantially as described.

In testimony whereof I have hereto affixed my signature in the presence of two witnesses.
