sTool. 0R CHAIR.
SPECIFICATION forming part of Letters Patent No. 595,352, dated December 1.4, 1897.
Appncation tied March 24. 1897.
To all whom it may concern,.-v
Be it known that I, JOSEPH W. SNELL, Jr., a citizen of the United States, residing at Bay Port, in the county of Huron and `State of Michigan,have invented'certain new and useful Improvements in Stools or Chairs; and I do 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 appertains 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.
This invention relates to improvements in raising and lowering seats of stools or chairs, and has for its object to provide a device of this character which combines the advantages of simplicity of design and cheapness of construction, thus rendering the same capable of more easy and quick assembling and adjustment of parts and at the same time increasing its efficiency and ease of operation.
To this end my invention consists in the construction and arrangement of parts, as shown in the accompanying drawings and set forth in the following specification.
In the said drawings, Figure lis a sectional elevation'of my device. Fig. 2 is a horizontal section taken on the line 2 2, Fig. 1. Fig. 3 is a similar view taken on the line 3 3, Fig. 1;' and Fig. 4 is a similar view taken on the line 4 4, Fig. 1. i y
Of the parts represented in the figures, A denotes a standard,which may be either round or rectangular in cross-section. vIt is provided at its top end with an enlargement O, at its inner edge with ratchets a, and near its upper end with bent arm b. Pivotally connected totop of standardA is seat B. Extendingparallel to main standard A is lever-rod D. This is a small rod pivoted at its lower end to standard A and at its upper end to fingerlever CZ, passing through and being held in position by passing through perforation f in arm b. Passing through the two perforations in arm b is finger-lever d, provided at its outer end with finger-rest h and pivotedat its inner end to rod D. Between the two outer perforations of arm b and encircling the nger-lever is a spring e, the outer edge of said spring resting against outer end of arm b and Serial No. 629,076- (No model.)
attached at its inner end to finger-lever d. (See Fig. 2.) Fitting into base J is the guide H, provided with a central perforation, through which the standard A passes and is held in Having now indicated the various elements composing my device,and the manner in which they are connected, the mode of operation is as follows: Spring e is so arranged that when inger-leverd is pressed in rod D, being pivoted to said linger-lever, is also pressed firmly in toward standard.
This
keeps the sliding detent j, through which rod D passes, inserted in notches a of standard A. To raise or lower the seat of stool or chair, press out on finger-rest h. This will throw rod D away from standard A, sliding detent j back from the teeth ot' the standard. The stool may then be raised to any desired point up to the place Where the' under-bent arm of rod D hits partition J of the guide H. (See Fig. l.) When the stool is raised to the desired point and pressure is released from the finger-rest h, the spring e will then firmly press rod D in toward the standard A, forcing sliding detent]l in ratchets a of said stan dard. The seat B is pivoted and will revolve without touching or changing location of the linger-lever. With the above construction it is not'necessary for the operator to leave the stool in adjusting the same.
It is understood that this invention is not' limited to the precise form and mode of arranging parts shown in the drawings, but that minor variations may be made therein, provided there is no departure from the main scope of the invention.
Moreover, while I have described my invention as more particularly designed to be applied to stools or chairs it will be understood that it may be used in connection with IOO analogous articles of furniture-s uch, for instance, as tables, lamp-stands, and the like. Having thus described my invention, what I claim is l. The combination with a su pporting-base, and a serrated standard vertically movable therein and supporting a top such as a stool or chair seat, of a vertical rod pivoted at itsv seat, and a horizontal arm or bracket supported by said standard near its upper end, of a vertical rod pivoted at its lower end to said standard, a pull-lever movable in said arm or bracket and pivoted to the upper end of said vertical rod, a spring engaged with said pulllever for normally retaining said Vertical rod in proximity to said serrated standard, and a detent sliding in guides in said base and controlled in its movement by said vertical rod for engaging with the serrations in said standard to retain the same in any adjusted position, substantially as described.
In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
