ARCHIBALD G. HAYNES, OF PHILADELPHIA, PENNSYLVANIA.
EPECIF'ICATIQIG forming part of Letters Patent No. 3%L'7l8, dated May 11, 1886,
Application filed August 10, 1885.
[0 aZZ whom it may concern:
Beit known that I, ARCHIBALD (J. HAYNES, a citizen of the United States, residing in the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Stools, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 represents a side elevation of a stool embodying my invention. Fig. 2 repre sents a front view thereof, partly sectional. Fi g. 3 represents a partial vertical section and partial side elevation thereof. Fig. 4; represents a top or plan View thereof, a portion being broken away. Figs. 5 and 6 represent vertical sections of detached portions on an enlarged scale. Fig. 7 represents a horizontal section in line 00 00, Fig. 1. Fig. 8 represents a "61" tica-l section of a detached portion of a modification thereof.
Similar letters of reference indicate corresponding parts in the several figures.
My invention consists of certain improvements in stools for pianos and other purposes, whereby the back, seat, and foot-rest are adjustable,and means are provided for preventing wabbling of the seat on the base portion of the stool.
Referring to the drawings, A represents the seat of a stool; B, the stem depending therefrom; C,the base in which said stem is fitted; D, the foot-rest,and E the back. On the sides of the back are plates F, which connect said back with the seat, the inner faces of said plates having tongues G, which enter grooves H in the sides of the seat-frame. The plates F are L-shaped, their lower limbs extending under the seat-frame, and having screws J, which enter grooves K on the under side of the seat-frame and tighten against the top walls thereof.
It will be seen that when the screws J are loosened the back may be moved forward or backward, and thus adjusted relatively to the requirements of the occupant of the seat, the screws J then being tightened for retaining the back in adjusted position.
It will be seen that during the adjustment of the back the tongues and grooves G H and screws J cause the platesF to move true, and thereby prevent the same from binding. The screws J being on the under side of the seatframc do not presentan objectionable appear ance, nor occupy places whereby they may catch the dress or clothes of the occupant of the seat.
The stem B has a ratchet, L, formed with or secured to it,and with the same engages a dog or pawl, M, the latter being fitted to the base 0, and pressed inwardly by a spring, N, which bears against said pawl and the adjacent portion of the base 0, as more plainlyshown in Fi 5, said pawl having secured to or formed wit-l1 it a handle, P, the inner end of which has a flat portion, P, which, when the ratchet and pawl are engaged, enters between two lips, Q. projecting from the side of the base 0. It will be seen that the seat may be adjusted in height. as desired.
When the handle P is drawn out, the pawl M follows the same and clears the ratchet L. The handle is then given a quarter-turn,whereby it rests on the lips Qat a right angle thereto and controls the pawl. \Vhenthe adjustment of the seat is accomplished,the handle P is again rotated a quarter-turn, and the portion P enters between the lips Q, the pawl then being forced by the spring M against the respective tooth of the ratchet L and serving to lock the seat to the base, holding .it in its adjusted position.
in order to prevent wabbling or lateral movement of the stem B, and consequently of the seat on the base, I employ a screw, R,
which is fitted to the base and has its point adapted to tighten against the side of the stem, so that any lateral lost motion of the stem in the base is prevented and the stem rendered immovable, it being of course heldin adjusted position by the action of the pawl and ratchet M L, as has been stated.
The foot-rest D is vertically adjustable on the upright portion or limb of an angular bar, S, the upper limb, S, of which is forked or bifurcated and horizontally fitted in eyes or bosses T on the sides of the base 0, whereby said bar S may be set in or out, thus accordingly adjusting the position of the foot-rest D.
In order to retain the bar S in adjusted position on the base 0, screws T are fitted to the bosses T and tightened against the forks S of said bar.
If desired, a single boss, T, may be placed in front of the base to receive the upper limb of the bar, in which case said limb is not forked, and a single screw, T, is sufficient to hold the limb from movement.
The foot-rest D is vertically adjustable on the bar S, as has been stated. For this purpose the vertical limb of said bar is toothed or serrated, or provided with a ratchet, U, with which engages a pawl or dog, V, the latter being hinged to the rear portion of the foot-rest and pressed against the ratchet by a spring, W, suitably applied. The pawl V has a knob or handle,X, for operating purposes, it being evident that by withdrawing the pawl the foot rest may be adjusted in height, after which the pawl is let go, and the rest then retains its adjusted position.
At the bottom of the bar S is a stationary foot, Y, which rests in the floor and serves to sustain the foot-rest and bar and prevent any tilting or overturning of the stool when a person steps on the foot-rest.
It Will be noticed that the bar S is attached to the base of the stool and thus disconnected from the seat, whereby the adjustments of the latter do not affect thefoot-rest, and vice versa.
In Fig. 8 I show the ratchet U sunken or Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is
1. The seat A, having the side grooves, H, and the bottom grooves, K, in combination with the back E, and the L-shaped plates F, connected therewith, having their lower limbs extending under the seat A, the side limbs being provided with tongues G, working in the side grooves, H, of said seats, the lower limbs having screws which Work in the grooves K, substantially as described.
2. A stool having a vertically adjustable Seat, a base receiving the depending stem of said seat, a holding ratchet and paw], and a laterally tightening-screw, substantially as described.
3. A stool with a base, in combination with a supporting-arm having a ratchet, the said arm being laterally adjustable on the said base, a foot-rest vertically adjustable on said supportingarm, a spring-pawl secured to the collar or sleeve of said foot-rest, embracing said supporting-arm, the latter having a foot thereon, substantially as and for the purpose set forth. I
4. A stool having a vertically-adjustable seat, a base, and a vertically-adjustable footrest, said foot-rest being connected with said base and adjustable without affecting the adjustment of the seat-,substantially as described.
