Application filed July 28, 1899.

Serial No. 725,350. (No model.)

To all whom it may concern:

citizen of the'United States, residing at Bans man, in the countyof Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Lawn-Swings; and I do hereby 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.

This invention relates to improvements in a swing of that class in which two oppositely disposed chairs are pivoted in position to the lower portions of hangers consisting of side bars or straps having their upper ends rigidly affixed to rods or shafts whose ends roll or rock in bearings arranged in the upper portion of the framework supporting the swing, said arrangement constituting the chief fea ture of the invention, in which an awning is arranged to shade the chairs. and a table provided between them, with a pivoted platform constituting a foot-rest for the occupants of the chairs. a

The object of the invention is to provide a portable article of lawn equipment for pleasure or recreation, to be used in private grounds, public parks, or other places of resort.

The elements of the invention will severally and at large appear in the following description, and they will be separately and collectively set forth in the appended claims.

The purposes of the invention are attained by the mechanism, means, and devices illus- I tratedin the accompanying drawings, similar reference characters designating like partsthroughout the several views, inwhich- Figure l is a perspective view of a fullyequipped swing embodying the elements of the invention. Figs. 2 and 3 are enlarged views, in side and end elevation, of aportion of the framework, showing the bearing supporting the upper end of the near hanger. Fig. 4 is an enlarged rear end view, in direct elevation, of a portion of the right-hand end chair in Fig. 2' detached from its hanger at joint-supporting strips in place, 1 Figs. 5 and 6 are elevations taken at apointai in Fig. 4,

showing the construction of said oscillating or rocking joints with the supporting-strips completed. Fig. 7 is a full side elevation of the left-hand end hanger detached from Fig. 1, showing pivoted thereto a chair without said oscillating or looking joints. Fig. 8 is a direct elevation, viewed from the right of the lower portion of Fig. 7, showing the spring or yielding back of the chair in full front view. Fig. 9 is a direct plan, horizontally placed, of the arm-rest detached froml ig. 8; and Fig. 10 is an end view of the awning-frame detached from Fig. 1.

.Nowfor the purposes of the invention the construction'com prises the supportin g-framework A, the swinging frame or rack B, the oscillating or rocking chair 0, the platform or foot-rest D, the table E, the awning F, and,

last but not least, the manner in which the upper ends of the hangers of the swinging rack are supported by the framework, especially the bearing of said support a. a

The supporting-frameA has four posts a, arranged in pairs, two on each side, having their upperends joined in the form of an inverted V and rigidly secured in any approved manner to the extremities of a tip cross piece or beam A, having the required length to gage the width of the framework, each inverted VcOnstituting a side thereof. These posts, together with the cross-piece a, preferably made of angle-bars of steel, arranged as shown in the drawings, and the posts have rigidly secured to their lower ends cross pieces or strips a, also of angle-bar metal, to constitute bases or feet supporting the frame-work on the ground and preventing the posts from entering thereinto at the height of the swinging rack yet to be described. On each side of the framework the end posts a are bound together by bars or beams A as shown, being rigidly secured thereto, as by rivets or bolts a and having their vertical flat sides cut away flush with the .outer faces of said end posts and their horizontal flat sides beyond said faces turned up into folds or recesses a constituting the hangershaft bearings before mentioned, while a plate a may be placed against the outer face of each post, and these plates are secured in place by the bolts 0., as shown, said plates serving as liners against the wearing of the hanger-shafts into the adjacent faces of the end posts at these points. Onto the bolts (1 are secured the ends of cross beams or bars A as shown, to hold the end posts crosswise in place, gaging the width of the framework at these points. In the spaces between the cross-bars A and the top piece A, with their lower ends secured onto the bolts of a and their upper ends rigidly secured to the sides of said top cross-piece near the extremities thereof, as by bolts or rivets of, are arranged cross-braces A assuring firmness or steadiness to the sides of the frame, while bracebars A with their upper ends secured to the centers of the side beams and their lower ends secured to the respective end posts, a, as shown, serve to assure firmness or steadiness to the ends of said frame, and to the top of the frame may be secured any ornamental finial A, as the scrollwork of scrap-iron, as shown in Fig. l.

The swinging frame or rack B consists of two hangers B, arranged in the opposite ends of the framework, as shown, each hanger having a rod or shaft 7) with its ends engaging or turned in the bearing-recesses a as shown, adjacent to said bearings. With their upper ends rigidly secured to said shafts b, as by being shrunk or driven thereon, are arranged straps or strips B B the forward or adjacent one, B being practically parallel to each other and somewhat longer than the rearward or outer ones, B These bars at prescribed points are provided with orifices b' b b b 17 5, as shown, completing the swinging rack and adapting it to pivotally support the chairs, the foot-rest, the table, and the awning.

In the construction of the swing two chairs 0 are used, being pivoted right and left to the hangers, one being on each side of the rack. Since the chairs are exact counterparts, one only will be described. In the construction of the chair two pieces 0 C of angle metal, are shaped as shown, being practically L-shaped in form to constitute the supporting sides thereof; To the horizontal portions of these sides are rigidly secured in any approved manner a number of slats or strips 0, constituting the seat portion of the chair, and the vertical portions constituting its back have rigidly secured to their upper ends a strip or board 0, and between this board 0 and the upper slat of the seat is arranged the yielding back 0 comprising two straps or strips 0 of spring metal, having their ends rigidly secured onto the forward faces of the side pieces 0 0 as by screws or rivets 0 said straps or strips (3 having secured to their forward faces, as by rivets, the required number of vertically-arranged strips or slats cfiand behind them are arranged cross-pieces O ,also of spring metal, with their extremities rigidly secured onto the rear end of the side faces 0 C by the bolts or screws 0 also securing the upper slat c of the seat and the top backboard c. In mounting the chairs 0 to their respective hangers pieces or bars 0 preferably of angle-bar metal, have their lower or forward ends pivoted to the hanger-straps B by pins or bolts through the orifices b thereof, and to the upper or rearward ends of these bars are rigidly secured plates 0, having inwardly-projecting flanges 0 along their lower edges, with their forward ends turned up to form stocks or seat-rests c for engagement against the lower edges of the chair sides pivoted thereto, as by bolts 0 passing through its side pieces 0' O and through the plates 0", as well as through one of the orifices b 'of the hanger-straps B as shown, while a torsional spring-rod G with one end 0 turned up through the side piece a of the chair and the other end 0 turned down through the flange c of the plate C adjacent to its side piece 0 serving to hold said chair in normal position, allowing it to oscillate or rock to and fro, as may be desired, and strips of pieces 0 are pivoted to the hanger-straps B B by bolts or pins through the orifices b B, as shown, constituting arm-rests for the occupants of the chairs.

At the lower end of the swinging rack is arranged the platform or foot-rest B, extending between the hangers, as shown. Extending from the straps B of the opposite hangers are pieces or bars (1, preferably of anglebar metal, having their extremities pivoted to said straps by pins or bolts passing through the lower end orifices b, and on top of said bar d are arranged crosswise pieces of slats b, as shown, and rigidly secured in place, as

by rivets or screws 11 At about the height of the chair-arms and between the hangers is arranged the table E, consisting of a practically rectangular board e, provided with rigidly-secured end strips or cleats E, having downwardly-sloping or inclined arms 6' adjacent to and passing by the inner sides of the hanger-strap B where said arms are provided with outwardly-projecting ends or fingers e, embracing said straps and resting on top of the forward ends of said chair-arms, securely supporting said table in position.

Extending longitudinally above the chairs, through the swinging rack, and between the side straps of the hangers is arranged the awning F, having a framework F, consisting of a ridge-pole f and two parallel side rails f, rigidly secured to and supported by two double pitched brackets F at a distance apart equal to the distance between theopposite hanger-straps B with which their extremities should register, said framework having been covered with any suitable awning cloth or material f, as shown, said awningbeing pivoted in place by pins or bolts f passing through the bracket ends, through the side rails, and through the orifices b of said hanger-straps, while fender-strips f are placed between the awning-cloth and the adjacent hanger-straps B B to prevent the fric- IIO tional contact or rubbing of the latter from wearing into or through the cloth when the swing is in motion. r 1

Whenso desired, the oscillating or rocking elements hereinbefore set forth may be omitted and thechair pivoted direct to the hanger straps, Fig. 7, and the pivoted armmay have the shape shown in plan in Fig. 9, all without materially affecting the character of the invention. I

It will here be remarked that steel isnsed in the construction of this invention in preference to any other metal in that it may have great strength, combined with extreme light: ness in Weight. It will also be remarked that portable lawn-swingsof various-types are old and well known to the trade; but thefollowin g instrumentalities used'in this construction are believed to be new: making the framework of steel with its system of bracing and the arrangement or construction of the bearings supporting the chair-hangers; making the chair hangers also ofi st,eel;, .each consisting of a sh aft with pairs'of depend g straps having overlapping uppeniaen ds grigidly secured to or shrunk onto sai'dishagftnear to the ends thereof, said ends being adapted to rotate or rock in said bearing-,rrmakjng thechairs of steel 7 and wood, provi'dii ng them with yielding or springing backs,"fian d;t.pivoting them to the hangers in the lower' portions thereof, so that they may rock freely or oscillate ontheir pivot-joints 3 making the platform of steel'and wood and pivotally sdpporting it at the lower ends of the hangers,'and making the table of wood and steel and supporting-it between the chairs and arranging an awning having framework of wood and steel above the'chairs and pivoting it to the hanger-straps, with fenders interposed to prevent contact of said straps with the covering of said frame.
