VILLIAM E. LATIMER, OF UTICA, NEW YORK, ASSIGNOR TO ELLEN R. LATIMER, OF SAME PLACE.
CHAlR-BACK-ADJUSTING DEVICE.
SPECIFICATION forming part of Letters Patent No. 614,963, dated November 29, 1898.
Application filed November 6,1897. Serial No. 7,629. No model To all whom it may concern.-
Be it known that LVVILLIAM E. LATIMER, of Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Chair-Back-Adjusting Devices; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form part of this specification.
Figure 1 shows a side View of a chair having my back-adjusting device applied. Fig. 2 shows parts of the chair and the device on a larger scale. Fig. 3 shows a partial assemblage of the mechanical parts. Fig. 4shows an edge view of the mechanical parts with the casing removed. Fig. 5 shows a vertical central section of the device. Fig. 6 shows a depending hanger or bracket employed in the construction. Fig. 7 shows in perspective the spring and body or core part of the device. Fig. 8 shows in perspective the swinging arm employed in the construction. Fig. 9 shows the connecting-rod.
Referring to the reference-numerals in a more particular description, 1 indicates the adjustable chair-back, hinged at 2 to the seat or body of the chair, which is provided with fixed or rigid arm 3. To the under side of the arm is attached a dependent hanger or bracket 4. In the bracket is firmly secured the core or body 5, having its rectangular end 5 engaged in the correspondingly- About one portion of the part 5 is coiled the spring 6, one end (3 of which is adapted to engage with the projection 5 on the part 5, and the other end 6 of the spring is adapted to engage with the adjusting-arm 7 by being passed through the hole 7 therein. The adjustingarm 7 has a bearing at its lower end on the reduced portion 5 of the body 5 and within the eye is provided with several catch-notches T The body 5 is provided with a slotted re cess, which receives the latch or catch 8, pivoted to the body at 9 and provided with a knob on its projecting end.
The swinging end of the arm 7 is connected with the back of the chair by a connectingrod 10.
On the exterior periphery of the enlarged lower end of the arm 7 is provided a projection 7, which is adapted to engage with the stop-pins 4 +1 in the bracket 4: and limit the swinging movement of the arm 7 in either direction. The working parts are inclosed in a cap or casing 11.
The tension of the spring 6 is such as to swing the arm 7 toward the front of the chair and through the connecting-rod 10 move the back of the chair in the same direction.
The operation is very simple and is as follows: The occupant throws his back against the chair-back with sufficient pressure to take the tension of the spring 6. Then with the hands the latch 8 or latches (a pair of devices being usually employed) are raised so as to disengage them from the notches 7 The back is then free to be moved farther back by further pressure or toward the front by the springs, as desired. WVhen in the desired position, the catches or latches are dropped and find their places in one or the other notches 7 and secure the parts in that position.
What I claim is- 1. The combination with a chair arm and back of the adjusting device consisting of a fixed body, a swinging arm, mounted thereon, a spring for operating the swinging arm, a latch or catch for securing the swinging arm and a connection to the chair-back, substantially as set forth.
2. The combination with the arm and adjustable back of a chair of an adjusting device consisting of a bracket secured under the arm, a swinging arm mounted thereon, a spring for operating the swinging arm, a latch or catch for securing the swinging arm and a connection to the chair-back, substantially as set forth.
3. The combination with the arm and adj ustable back of a chair of an adjusting device consisting of a fixed body, a swinging arm mounted thereon, a connection between the swinging arm and chair-back and a latch or catch for securing the swinging arm substantially as set forth.
l. The combination with the arm and adjustabie back of a chair of an adjusting device consisting of a fixed recessed body, a swinging arm mounted thereon, a connection between the chair-back and swinging arm and a latch contained in the recess of the body and adapted to engage and secure the swinging arm, substantially as set forth.
5. The combination with the fixed chairarm and adj ustable chair-back of an adj usting device consisting of a bracket secured to the chair-arm, a fixed body mounted on the bracket, having a recess, a swinging arm mounted on said body having internal notches, a spring for operating the swinging arm, a latch contained in said recess and adapted to engage in said notches and secure the swinging arm and a connection between the swinging arm and chair-back, substantialiy as set forth.
In Witness whereof I have affixed my signature, in presence of two witnesses, this 3d day of November, 1897.
\VILLIAM E. LATIMER.
Witnesses E. W. JONES, RICH. A. GEORGE.
