SPECIFICATION forming part of Letters Patent No. 224,857, dated February 24, 1880.
* Application filed September 2, 1878. l
v To all whom it may concern:
Be it known that I, M. HOFFMAN WILSON, of the city of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Piano Stools; and I declare that the following is a clear, exact, and perfect description thereof, reference being had to the accompanying drawings, in which- Figure 1 is an elevation showing stool when closed for use as a single stool. Fig. 2 is an elevation of the stool when extended for use as a double stool, with a second seat on the extra stem. Fig. 3 is the inside face of one division of the pedestal of the stool, showing one stem and the slots for the braces, with the seat in section. Fig. 4 is a vertical longitudinal section of the stool partly extended, showions of the pedestal of a piano-stool,
ing the action of the braces and arrangement of the movable seat. Fig. 5 is a view of the end hinge of the lower brace. Fig. 6 is a view of the end hinge of the upper brace and the head of the screw-stem upon which the movable seat is to be placed. Fig. 7 is aside view of the middle hinge of the top brace when locked. Fig. 8 is the same when unlocked.
The object of my invention is the construction of a piano-stool which may be used either as a single or a double stool.
The nature of my invention consists, first, in the use of a pedestal divided vertically, each division of which incloses and supports a screw socket, in which a screw rod or stem works, provided with braces, and so arranged that when the divisions are separated from each other the two screw-stems may each support a seat capable of being raised or lowered independently of each other, thus enabling its use either as a single or double stool; second, in details of construction.
In the drawings, 0 and D represent diviseach of which contains an upright screw-rod working in a screw socket or nut.
EE and F F are rods in pairs, hinged at their outerends to the divisions O and D, and at their inner ends to each other, in such manner that the rods E E, folding downward, and rods F F, upward, when closed outer grooves J on the inner faces of divisions G and D.
Alug or projectionon one of the rods E extends beyond the central hinge, and, when the divisions are extended, rests in a recess along the other rod E, to which it is firmly bound or clasped by a band which is slid over it. This arrangement. constitutes a brace, and, in connection with the rods F, which are hinged to close upward, serves to keep thedivisions O and D rigidly in position when extended. 1
O and H are screw-stems on rods extending vertically through the divisions O and D and working in screw sockets or nuts.
When the stool is used singly a seat, B, is placed upon the stem 0. This seat B has an outer rim, S, so arranged as to receive and support another seat, A, shaped on the under side to contain the seat 13, with a flange, Q,
fitted to and over the rim S, and, if desired, it may be packed with rubber. When in use as a single seat the seat A is placed upon the seat B; but when the divisions O and D are extended the seatAis removed from the seat 13 and placed upon the stem H, and to facilitate which and secure the seat a head shaped like the frustum of a pyramid is secured to the 'upper end of the stem and fits into a corresponding socket inthe center of the bottom of the seat A.
To assist in supporting the seats when extended feet are placed. on the bottom of the divisions G and D, in line, or nearly so, with their inner faces.
. The divisions (l and D, when closed, are held together by a catch, L, or other suitable device.
Havingdescribed my invention, what I claim to be new, and'desire to secure by Letters Patent, is-
1. In a piano-stool, a vertically-divided pedestal, each division of which ishollowed to receive a screw-stem working in a screw nut or socket, arranged substantially as described,
so that when closed one of the stems is sur- 5. In a piano-stool, the seat B, provided with a rim, S, constructed to receive and support 15 a second seat, A, whose outer edge is provided with a flange to fit upon the said rim S when said stool is closed and said second seat A removed from the stem H.
