CHAIR.
SPECIFICATION forming part of Letters Patent No. 626,139, dated May 30, 1899.
Application filed October 29, 1898. Serial No. 694,899. (No model.)
To all whom, it may concern:
Be it known that we, WINDSOR O. CAMPBELL and EVA K. CAMPBELL, of Sulphur Springs, in the county of Benton and State of Arkansas, have invented a new and Improved Chair, of which the following is a full, clear, and exact description. I
This invention relates particularly to improvements in piano chairs or stools; and the object is to provide achair of simple construction, the seat of which may be easily and quickly raised or lowered.
We will describe a chair embodying our invention, and then point out the novel features in the appended claim.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 is a sectional elevation of a chair embodying our invention. Fig. 2 is a section on the line 2 2 of Fig. 1, looking in the direction of the arrows; and Fig. 3 is a transverse section of the chair.
Referring to the drawings, 1 designates a frame supported by legs 2. Mounted to swing in the frame 1 are levers 3 4, the outer end of the lever 3 being connected to a shaft 5,1nounted to rock` in brackets 6, secured to the under side of the chair-seat 7, and a shaft 8, connected to the outer end of the lever 4, is mounted to slide in slots formed in brackets 9, secured to the under side of the seat. Links 10 11 connect the inner ends of the levers 3 4 with a sleeve 12 mounted to slide on a rack 13, which is connected at its upper end with the frame 1, and at its lower end to a block 14, supported by the legs l. -Pivoted to the sleeve 12 and adapted to engage with the rack 13 is dog 15, and Vthis dog 15 is held yieldingly in engagement with the rack by means of a spring 16, arranged between the horizon tally-disposed member of the dog and a plate 17, extended outward from the lower end of the sleeve and serving as a handle.
In operation by moving the sleeve downward on the rack the outer ends of the levers 3 4 will be swung upward, and consequently tended from its lower end, connections between said sleeve and the inner ends of the levers, a dog mounted on the sleeve and adapted for engagement with the rack, and a spring arranged between the dog and handle, substantially as specified.
