REVERSIBLE R ECLINING RAiLROAD-COACH CHAIR.

Specification of Letters Patent.

Patented May 29, 1906.

Application filed August 26, 1905. Serial No. 275.913-

To all whom it may concern:

Be it known that we, Lawson TARWATER and CHARLES K. MCKNIGHT, citizens of the United States, residing at St. Joseph, in the 5 county of Buchanan and State of Missouri,

have invented certain new and useful Improvements in Reversible Reclining Railroad- Coach Chairs; and we do declare the following to be a full, clear, and exact descri tion of the re invention, such as will enable ot ers skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form a 1 5 part of this specification.

The object of'our invention is to provide.

an improved reversible coach-chair that may be adjusted to any position from u right to horizontal and which, being rovi ed with an adjustable head-rest and cot-stool, will serve as a couch as well as chair.

We accomplish our object by the mechanism illus trated in the accompanying drawings in Which Figure 1 is a side elevation of the chair in its normal position; Fig. 2, a front elevation of the same; Fig. 3, a detail of the bottom of the chairseat, showing lever connection with a cross-bar carrying a lug (shown by dotted lines) that engage with the two-way teeth on a plate attached to the bottom of the seat; Fig. 4, a detail of .a slotted guide and the prongs on the lower end of one of the chairack metal side strips and the pins which en- 3 5 gage with the slot and prongs; Fig. 5, a detail of one of the channel-bars and rollers bywhich the chair-seat is carried, and Fig. 6 is a detail of the mechanism by which the head-rest is adjusted.

Similar letters refer to similar parts throughout the several views.

A A represent the legs and connecting parts of the chair-frame, and B B the sides of the chair-frame, on-which arms C O are sup ported.

D is a chair-seat adjustable to any ositi'on the chair may assume, E an adjustab e back, I

and H an adjustable head-rest. The side edges of back E are provided with flat metal strips I I, which project up the sides of headrest H, being enlarged at their upper ends and gIQVldGd with teeth formin racks J J.

and strips are rigidly attache to the chairback, but arepivoted, by means of pins h h, to

the head-rest to allow it to be adjusted backward and forward. Said head-rest is provided with a rod K'and a spring L and a knob K at one end and lug L at the opposite end; This spring-rod 1s provided at the inner side of knob K with a shoulder O, which when the rod is in its normal position enga es with the teeth on rack J, while lug meshes with'the teeth on rack J.

When knob K" is drawn slightly out from the 5 teeth of rack J, and at the same instant lugL head-rest, said shoulder 0 passes outside the is drawn within the aperture in the head-rest in which the rod operates. RacksJ and J being thus released, the head-rest can be moved forward or backward to the desired angle, and the rod springing back the shoulder and lug at once enga e their respective racks an hold the hea rest in the desired position. The lower ends of metal strips I I are forked,

- the ends of the two prongs 7 j on each turned slightly toward each ot er andadapted to engage loosely with pins (1 d. On the sides of seat D,near the chair-back, above prongs y' j,

arev ins e e, .which engage with slots (1 (1 1n 1 gui es D D, which guides are pivoted at their other ends to the inner sides of seat. A hand-lever P opgerates vertically through chair-frame piece end with an arm p, adapted to operate horizontally. On the projectin end of this arm a cross-bar P is pivotally astened, the. opposite end of said bar being supported by and operating in a hole or slot 1). 1n the opposite side piece B. A coil-spring Q is rigidly fastened at one end to said side B at a point slightly below said slot, the opposite end of the spring being rigidly fastened on the cross-bar. Onthe top of said cross-bar is a lug A metal plateR, rovided with right an left teeth 1' 1', is rigid fastened on the bottom of seat D at a rig t angle with cross-bar P. In the side edges of seat D channel-bars S S are countersunk, and attached to the insides of side pieces B B are rollers T T, on which said channels-bars are adapted to travel when the seat is released. To drop the backof the chair to any desired incline or to a horizontal position, hand-lever P is revolved a half-turn.- releases lug g from e agement with teeth 7" r on plate R, and t e seat being drawn slightly forward the bottom of the chairback will follow until it has resumed the deand is provided on its I roo This

, sired incline. Upon releasing the hold upon the lever said lug will again instantly en age one of-said plate-teeth and hold the bac at an incline or at a horizontal, as desired. The chair is made reversible by having one-half the teeth on plate R cut in opposite direction, as shown by Fig. 3, and by means of the slotted guide-rods D D,hereinbefore described, and the reversing and back-supporting rods Y Y, which are pivotally attached at the middie of the side pieces of the chair-back.

V is afoldable foot-rest adapted to be carried in guides V V underneath the chair-seat and to be drawn out as wanted. Said foot-rest is constructed with a hinged foldable extension at front and back, thus adapting it to be drawn out in opposite direction when the back of the chair is reversed. If it is desired to construct the foot-rest-wider than shown, it can readily be changed by allowing guides V V to be cast in lower extensions of the channel-bars S S.

What we claim, and desire to secure by Letters Patent, is-

1. In a reversible reclining chair the conibination of a chair-frame, a seat and the channel-bars and rollers at the sides of'the seat permitting it to be moved forward or back ward, a chair-back and head-rest, metal strips rigidly fastened to the sides of the chair-hack and the prong ends thereof engaging with pins on the rear ends of the seat sid'e pieces, slotted guides forming connection between said side pieces and said strips and the reversing supporting-rods pivotally connected with said side pieces and metal strips, a lever and an arm thereon, a twoway toothed plate rigidlyfastened on the bottom of the chairseat, a ross-bar at right angles with said plate atfached at one end to said. lever-arm the other end operating in a slot in a side piece, a lug on said cross-bar and a spring adapted to draw and hold said lug back in engagement with said teeth after being withdrawn by a half-turn of said lever, a rod and spring operating in said headre'st, a shoulder and lug on said rod adapted to engage the racks at the upper ends of the metal strips on the chair-back and allow said head-rest to be adjusted, and a foldable adjustable footrest and the guides therefor spaced below the seat, substantially as described and shown.

2. In a reversible reclining railway-coach chair the combination with the chair-frame, arms, seat and back, of vertical strips rigidly fastened to sides of the chairback and the prongs thereof engagin with pins on the sides of the seat near the nick, slotted pivoted guides forming connection between the sides of the seat and said vertical strips and reversingsupporting-ro ls pivotally connected with said seatsides and the chair-back, a lever supported by a side piece of the frame and an arm thereon, a twoway toothed plate rigidly fastened on the bottom of the chair-seat, a cross-bar at right angles with said plate attached atone end to said lever-arm the other end operating in a slot in the opposite side piece of the frame, a lug on said crossbar and a spring adapted to draw and hold said lug back in engagement with said teeth after bein withdrawn by a half-turn of the lever, substantially asshown and described.

3. The combination with the frame and seat of an adjustable chair, of a hand-lever adapted to be operated through a side piece of said frame and the arm thereon, a two-way toothed plate rigidly fastened on the bottom of said seat, a cross-bar at a right angle with said plate attached at one end to said leverarm the other end operating in a slot in the opposite side piece of said frame, a lug on said cross-bar and a spring adapted to draw and hold said lug back in engagement with said two-way teeth when disengaged therefrom by withdrawal by a half-turn of said lever, substantially shown and set forth.

in testimony whereof we allix our signatures in presence of two witnesses.
