To all whom it may concern.-

Be it known that we, LAWSON TARWATER and CHARLES K. MOKNIGHT, citizens of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in a Revoluble Reclining Railroad-Coach Chair; and wedo 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 appert'ains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference'marked thereon, which form a part of this specification.

Our invention relates to a revoluble reclihing-chair especially adapted to use in railroad-coaches, and we accomplish our object by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a front elevation of the pedestal, chair, and foot-rest thereon; Fig. 2, a side elevation of the chair, pedestal, foot-rest, and mechanism for carrying the back of the chair to an inclined position and the seat and footrest to a forward position. Fig. 3 is a detail of a section of the pedestal and top plates provided with grooves and ball-bearings, an L-shape strip countersunk in the pedestal, and a locking device. Fig. 4 is a detail top view of the lock-rod held in a recess between two shoulders. Fig. 5 is a detail of a channel-bar'and one of its rollers. Fig. 6 is a detail of mechanism under the chair-seat, showing the lever connection with a cross-bar and its lug, shown by dotted lines, that engages with teeth on a plate fastened rigidly to the seat-bottom and Fig. 7 is a detail top view of the pedestal-plate groove, showing one of its partitions and ball-bearings.

Similar letters refer to similar parts in the several views.

A A represent the chair pedestal and frame,B the chair-seat, and C the chair-back, hinged at its bottom to the back of the seat.

The arms D D are pivoted at their front ends to frame-posts A A and at the rear ends to.

the back of the chair. To permit the chair to revolve, we attach a plate E rigidly on the top of the chair-pedestal E, and 'a plate F,

spaced from the bottom of the chair-seat, is carried by frame-pieces of the chair. In these upper and lower plates are corresponding circular grooves e e, in which ball-bearings H H are adapted to travel. To prevent 5 5 said ball-bearings massing in one part of the groove, we provide partitions h h with one or more bearings for each division. Two metal L-shape strips rigidly attached at their upper ends to opposite side edges of plate F en gage with and travel in groove 1, which encircles said pedestal. These L-shape pieces are adapted to securely hold the chair in po sition. The front edge of plate F is provided with duplicate rounded shouldersJ J, which form a recess J. A vertical rod K is pivotally carried at its lower end by brackets 7c k on the front of the pedestal. At the front of said rod there is a spring K, which constantly bears against it,holding the upper end in re, cess J and preventing the chair being revolved unless released by the porter or other person by drawing said rod out of the recess by the use of a hooked pin or other device inserted into perforation in the top of said rod. Frame-pieces A A at the sides of the seat are provided with rollers M M, and the side edges of the seat are provided with channel-bars M M, adapted to engage with and travel on said rollers. If preferred, this arrangement may be reversed without altering the scope of our invention, said rollers being attached to the side edges of the seat and the channel-bars countersunk in the frame-pieces. Two cleats O O are rigidly attached at their upper ends on the lower part of the back of the chair. A foldable footrest P is carried by two supporters P P, pivotally attached to the front edge of the seat. Connecting-rods O O are attached pivotally to the bottom ends of said cleats and to said supporters at points about half-way between the chair-seat and the foot-rest. Rigidly fastened on the bottom of said seat centrally between front and back is an elongated plate Q, 9 5 provided on one edge with a plurality of oneway teeth q q. Below said plate, at right angles therewith, is a metal strip Q, with a sin gle projecting lu q adapted to engage with the teeth on said plate. This strip engages Io'o loosely with a slot (1 (shown by dotted lines in Fig. 6) in one of the side pieces of the frame of the chair. Upon the opposite side alever R operates vertically through a frame-piece carrying a rigidly-fastened arm S, which pro- 10 5 jects at a right angle with strip Q and on the projecting end of which said strip is pivoted. Below the slot in which said strip operates in the frame piece a coil-spring T is rigidly attached at one end, the other end being rigidly fastened to the bottom of said strip, preferably in proximity to plate Q. By a half-turn of lever R said strip is drawn partially out of its slot, this movement releasing said lug g from its normal position of engagement with teeth (1 g on plate Q. While the lever is thus held at its half-turn, the seat of the chair remains released, and the chair can be readily adjusted to the desired incline. Thelever being released, spring T will instantly draw the end of strip Q into its normal position in its slot, thus carrying lug g into engagement with other teeth and holding the chair in its changed position. What we claim, and desire to secure by Letters Patent, is p In a r'evol'uble reclining coach-chair the combination with the pedestal, frame and back, of arm-posts at the front of the frame,

' arms 'pivotally attached to said posts and the sides of the chair back, cleats extending downwardfrom the chair-back and rigidly attached thereto, a foldable foot-rest and the duplicate supporters therefor pivotally carried on the front edge of the seat-frame, duplicate rods havin pivotal connection with said supporters an cleats, a plate rigidly fastened on top of the pedestal provided with a partitioned groove, a plate carried by the chair-frame spaced below the chair-seat and provided with a groove, the roller-bearings adapted to travel in said partitioned groove, L-shape metal strips ri idly fastened to the edge of the top plate an adapted to travel in a groove in the pedestal as the chair revolves, shoulders forming a recess and brackets pivotally supporting a lock-rod provided with a perforation in its upper end and adapted to engage with said recess and a spring to hold said rod back in said recess, channel-bars and their rollers between which the chair-seat travels backward and forward, a lever and its arm carried in a side frame-piece, a strip pivotally attached to said arm at one end, the

opposite end carried in a slot in an opposite frame piece, a lug thereon projecting upward and a plate at aright angle with said strip rigidly attached to the bottom of the chair-seat and provided with one-way teeth withwhic'h said lug is adapted to engage, substantially as shown and described.

In testimony whereof we aflix our signatures in presence of two witnesses.
