ADJUSTABLE CHAIR.
srncmcnrron forming part of Letters Patent No. 687 769, dated December 3, 1901.
Application filed March 27, 1901. Serial No. 53,131. (No model.)
To aZZ whom it may concern:
Be it known that I, GEORGE W. MYERS, a citizen of the United States of America, residing at Hartford, in the county of Hartford and State of Connecticut, have invented a certain new and useful Improvement in Ad.- justable Chairs, of which the following is a description, reference being had to the accompanying drawings, wherein Figure l is a side elevation. rear elevation.
The object of the improvement is the production of a chair with an adjustable back having certain features of novelty and advantage.
In the accompanying drawings the letter Ct denotes what may be called the seat-frame as a whole.
The letter 1) denotes the back, which is hinged to the seat-frame and which has side rails which are ratched underneath.
The letter 0 denotes a frame which is pivotedatits lower end to the seat-frame. It has side rails which bear against the inside of side rails of the back I).
The letter at denotes spurs which are attachedto the side rails of the frame, being adapted to cooperate with the notches of the ratches and being also prolonged into operating-handles, which preferably are knobs. The frame is provided with one or more stops Fig. 2 is a e, which by striking the floor at the proper time prevent that frame from swinging too far backward and thereby becoming disengaged from the back.
It is one special object of my improvement to produce a chair with an adjustable back which may be readily operated by a person sitting in the chair and which preferably may be operated by one hand, and the fact is that a person sitting in a chair of this conratches out of disengagement with the spurs and also move the spurs to a new engage-- ment.
I claim as my improvement- In "combination, the seat-frame, the back hinged to the seat-frame having its parts im-' movably secured together and provided with side rails notched underneath, aframe cpivoted at its lower end to the seat-frame and having side rails bearing against the inside rails of the back, spurs carried by said frame a, and adapted to cooperate with the notches in the chair-back, and stops arranged at the lower end of the frame a to limit its movement in one direction, as and for the pnr poses specified.
