E. c. RANKS, or BOSTON, MASSACHUSETTS.
Letters Patent No. 87,111,
dated Februc/ry 23, 1869.
IMPROVE!) RECLINING-CHAIR The Schedule lreferred to in these Lettere Patent and making part of the sama.
To all whom it may concern Be it known that I, E. C. BANKS, of Boston, in the county of Suffolk, and State of Massachusetts', have invented an Improvement in Reclining-Chairs; and I do hereby declare that the following, taken in connection with the drawings-which accompany and form partof this specification, is a description of luy-invention suiiicient to enable those skilled in the art to practise it.
The invention relates particularly to the construction of that class of reclining-chairsl` in each of which the seat-frame, the back-frame, the foot-frame, andthe arms are jointed together, the seat moving slightly forward, and the arms back, as the sitter moves from up- .right sittin gposture to a reclined position, the improve- .a notched latch-bar, which rests, by gravity, againsta pin, with which its notches engage, the bar being hinged,
' at its front end, to the leg or foot-frame, in such man-v ner as to be moved forward and back by the forward and back movements of this frame, Athe bar sliding freely forward or back, when raisedby a lever-arm aty the end of a shaft projecting through the stationary cross-piece at the side of the chair, (which shaft bears a knob, by turning which the latch-bar is raised,) and dropping into engagement with the stop-pin at any point, when released from the hand of the occupant of the chair.
The drawings represent the frame-work of a reclining-chair embodying my invention.
A represents a vertical section, showing the parts in place for a person to sit in upright position.
B is a vertical section, showing the chair f extended.
a denotes the stool, or stationary part of the chair,
composed of the legs l), side rails c, and cross-bars d.
c denotes the swinging frame, which supports the feet and legs when thcchair is extended.
f is the swinging back, or back-frame.
The back is pivoted at bottom to the side rails c, by pins g, and the frame c to the rails c by pins hl, the frame fswinging freely back, and the frame e freely forward, on their respective pivots. s
Just below each two pivot-pins g h, one of the side rails rof the chair-seat is hung to the frames e f, as seen at A, while above the pins g h, the opposite ends of each arm It are hinged to the respective frames, as seen at A and B, the arms and seat, and the front and back frames having, by their connections, a simultaneous movement, as will be readily understood, the chair, as respects the arrangement and movement of all these parts, being not materially unlike other reclinng-chairs in common use.
To one of the side pieces of theY frame c, I hinge a notched or toothed latch-baal, the bar swinging loosely on its hinge, and extending back through a slot in a guide-plate, m, through which 'extends a cross-.pin or shaft, a, which, projecting through the adjacent stationary side rail, has fixed upon its end a knob, o, by means of which-rotative movement is imparted to the pin.
Upon this fpin the latch-bar rests by` gravity, the pin entering the notch above it, and acting as a stop, to arrest longitudinal movement ofthe latch-bar, thereby locking the back and leg-frames f e in any position into which they have been carried by movement cf the occupant'of the chair.
The latch-bar is made thicker above the notches, or with a shoulder, p, against which the end of an arm, g, on the pin n, acts, to lift the bar from engagement with the pin when the knob o is turned by the hand of the occupant, thelatch-bar sliding freely upon this arm when so raised, thereby enabling the chairto be more or less inclined by movement of the body, the latch-bar falling, upon release ofthe knob, and arresting and locking the chair in position, as before described, preventing movement of the frames e and f in` either direction.
It will be seen that this locking and releasing-mechanism is exceedingly simple and effective, requiring less than'a quarter turn of the knob to lift and release the latch,.while it locks itself.
' The hinge-plate r, to which the latch-bar isjointed,
screws and loosen the plate. To obviate this, Iextend- 'astrap-piece, s, from the hinge-plate fr, and angular thereto, as seen at B, fastening this by a screw, (or by screws) which, extending into the frame-piece at nearly a right angle to the other screws, securely holds the hinge-plate,l so thatit cannot he'drawn off or loosened by strain.
1 claim, in combination with the swing-frames e j,
the shouldered notched latchfbar l, locking-pin n, and lifting-lever q, constructed and arranged to operate together, in the manner and for the purpose substantially as described.
I also claim, in combination with the hinged lockingbar l, the angular strap piece 'r s, applied substantially as shown and described.
