RECLlNINGIND SWlN GING CHAIR.

SPECIFICATION forming part of Letters Patent No. 648,740, dated May 1, 1900.

Application ma October 7,1898.

To all whoritit may concern: Be it known that we, JOHN D. HAGGARD an HENRY II. MARCUSSQN, citizens of the United 7 it appertains to make and use the'same.v

. This invention relates more especially to improvements in that class of chairs that are designed for out-of-door use, and has for its objects to simplify the construction, increase 4 ---the convenience and-comfort,-and to provide adevice of this character that will fold up compactly for storage or shipment.

Figure 1 is a view in perspective of a chair embodying the improved features. Fig. 2 is an elevation in perspective of the companion supporting-standards. Fig. 3 is a side eleva- 'tion showing the chair folded compactly for storage or shipment, the independent supporting-standards being omitted? Fig. 4is a broken-away longitudinal section of an adjustable roller for keeping the covering fabric taut on line 4, Fig. 1, looking in the direction indicated by the arrow. Fig. 6 is an end view of the same; a Fig. 6 is a broken-away lan away plan of the detachable conneotionsof the independent standards on line 7, Fig. 1.

The framework comprises a system of levers and bars composed of thin flat metal pivoted or otherwise joined together and adapted to .havean automatic movement and adjustment in gradually changing froma sitting to are:

Y clining or recumbent position.

a coiled underto form the feet a,"the vertical center bars A A, rigidly. secured at their l'owerfends to the longitudinal center of the A A may represent a pair of independent supporting standards sep'arably connected together and between which the chair proper is supported in a suspended swinging position. These standards comprise the horizontal foot-bars A A, having therespective ends foot-bars, as at a, their up r ends being bent overiand inwardly, seat a from whiehpoint Serial No. 692,884. (No man.)

The connecting cross-bar is in two parts instead of being a single piece and is braced and stayed. The horizontal cross-bar in this instance consists of the companion sections A A, which extend part/way across under j the'seat. The respective outer ends of these bars are pivoted, as at a to the vertical bars A the inner ends overlapping in parallel planes, as shown in Figs. 1 and 7, a'portion of the seat-covering being broken away in.

Fig. 1, showing the relative position of the connections. The outer ends of the companion diagonal braces A A? are. pivoted to the lower part of the center bars of the standards and their inner upper ends inserted between t-he two-part cross-bar and detachably secured thereto by bolts a, as shown in Fig. 7. It will be noted that the two parts forming the cross-bar overlap approximately one- 1 half their length, so that the bolts a, making .the two joints, pass through the longitudinal center of one part through the ends of the diagonal braces and the end of the. other overlapping part. By taking out the two bolts a one part and one brace may be folded up parallel withthe vertical bars A and the standards-disconnected, as shown in Fig. 2, so that 'they may .be arranged compactly for storage or transportation. 1

,The chair-frame comprises the back sidei bars B,the seat-bars B, and the leg-bars'B, all pivoted together at their junction, 80' that' they may be made to assume difierent angles relative to each other' in the adjustment of the'chair from one position to another. The

lower ends of the back side bars extend-be- 5 low the seat-bars and are securedto the rear ends ofcompanion clamping-bars B by a bolt a, inserted through bolt-holes b, Fig. 3.

The front ends of bars B are pivoted, as at I b, to the longitudinal center of the lever-"- plates B, normally in a vertical plane. The

upper ends of these'lever-plates are pivoted, as at bfi to the respective seat side bars B.

the chair is suspended,and the inclined buses The amino! communion links C are nected by a pivot b to the lower end of the lever-plates and the front ends pivoted to the leg-bars, as at b. The-front ends of companicn clamping-bars C are attached to the lever-plates B! by the pivot b',passing through the front'ends of the bars B. The back unattached ends of these clam pingbars are provided with a screw-threaded aperture for the engagement of a screw-threaded hand-bolt d, inserted through the bars B from the outside and havinga clamping-head bearing against the surface thereof, as shown in Figs. 1 and 6. By tightening or slacking up on this bolt the pressure is increased or lessened on the pivotjoints at this point and the adjustment or movement of the chair parts regulated. When new, the pivotrjoints do not work too freely and the clamping-bars are left slack. As the iointsloosen up from use the clamping-boltmay be tightened and a proper tension maintained. These diiferent parts are all in duplicate, the opposite side of the chair from that illustrated in Fig. 1 being the same.

The lower ends of the suspending-bars D are secured to the side seat-bars by the pivot i, the upper perforated ends detachably engaging with'the lower hook end of the double nooks D and the upper hook end engaging with the bent-around ends of the vertical standard-bars A. The outer lower ends of the ius'pendingbars D are pivoted, as at d, to .heside bars of the back, the inner perforated ands also'deta'chably engaging with the lower iookends of the hooks D. By simply disingaging the-upper ends of the suspendingmm D and D the chair proper may be lifted lot from between the supporting-standards ind folded inwardly flat upon itself, bringng the head part and foot-rest intothe rela- ;ive position illustrated in,Fig. 3. The bolts t at each side, connecting the lower ends of she back side bars and the rear ends of the HHS B, should be removed preparatory to 'olding up.

' The angle -bar E oi the foot-rest has its re spectiv'e right-angle ends pivoted, as at d, to

ill! lower ends of thecompanion leg-bars B.

l he lower ends of the companion inclined n-acesdl are pivoted to the opposite ends of LhO fOOt-lGSU, as at d, the upper ends being;

letachably secured to the leg-bars by bolts l. These inclined braces may be provided with a number of apertures g, disposed at in-j ervals, so that the foot-rest ca'n .be-adjusted o diderent positions or folded up flatly by screwing the bolts d.

'.,The covering fabric F.ivill ordinarily be of ianvas and is kept taut by a nuinber of ension or stretching rollers G G G. .These ollers are all of. the same construction, and description of roller G, located in the upper ind of the chair and illustrated in Figs; 4 and" twill answer for the others. 'The upper and f the canvascover is mountedon the roller i;provided' with a ferrule g on each end hereof and whichis provided with a screwhreaded'nperture for the reception of the the frame-bars and prevent the rollers from turning accidentally. By slacking back on the screws g far enough to free the lugs g Y from engagement the roller may be turned to take up the slackin the chair-covering. The

roller G'jis located in the rear of the junction of the back and seat parts'and issupported by the rearwardly-extended curved ends it of the side seat-bars B. The roller G: is supported between the leg-bars and has the'lower end of the chair-covering mounted thereon. Ordinarily after the covering has been set taut the proper tension may be maintained with the'lower roller only.

The chair structure is strengthened and braced at the junction of the seat and leg bars by a cross-bar H. I

The construction and connections are such as insure an easy automatic adjustment entirely controlled by the movement of the body and any position assumed between an upright sitting position and a recumbent one.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, isv 1. In a chair of the class described, the

combination with the independent supporting-standards, of the connecting two-part cross-bar, consisting of companion sections, the inner ends of which overlap each other KOO about one-half their length, the companion diagonal braces, ,the outer ends of which are connected to the respective standards and the inner ends joined to eachof the two-part cross bars, and the joiningbolts inserted through the innerendsand the longitudinal center of the two parts of the cross-bar and through the inner ends of said braces andforming a rigid connection as a whole, substantially as described.

2. In a chair of the class described, the,

combination with the supporting-standards,

of the twopart cross-bar, detacha'bly connecting said standards, the inner ends of said cross-bar overlapping each otherapproximately one-half their length, the diagonal braces, secured at their; outer ends. to said standards and their inner ends to the crossbar and the joining-bolts, each of which pass through the end .or one part of the cross-bar,

through the inner end of one of the braces and through the longitudinal center of the other part of the cross-bar, forming a rigid connection, substantially as described.
