J. R, PEARTRER PIANO STOOL.
Patented Sept. 5, 1893.
UNITED STATES PATENT OFFICE.
JOSEPH R. PEARTREE, OF ROCHESTER, NEX/ YORK, ASSIGNOR OF ONE-HALF TO PETER ZINK, OF SAME PLACE.
PIANO-STOOL.
SPECIFICATION forming part of Letters Patent No. 504,683, dated September 5, 1893. Application filedMay 4, 1893. Serial No. 473,021. (No model.)
To all whom t may concern:
Be it known that I, JOSEPH R. PEAETEEE, of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in Piano-Stools; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the drawings accompanying this application.
My improvement relates to that class of piano stools, having a tubular standard, in which the seat is raised and retained at any adjustment by means of a rack bar and an engaging dog.
The distinguishing feature of my invention is a lifting ring located directly under the seat, and certain connections between this lifting ring and the dog by which the latter is disengaged from the rack to run the seat down, the construction also being such that the seat has a free turning movement independent of the adjusting mechanism.
In the drawings-Figure lis a central, ver tical section of a piano stool showing my improvement. Fig. 2 is an enlarged longitudinal, vertical section of the upper portion under the seat. Fig. 8 is a cross section in line m x of Fig. l. Fig. e is a similarfenlarged section inline y y of Fig. l.
A indicates the base, B the standard, and C the seat, of ordinary construction.
D is a tube attached lixedly in the standard, and E is a second tube resting within the rst, vertically movable and carrying at its upper end the seat O.
The exterior tube D is made in two half sections D D', which are cast separately and tted together and inserted in the opening made for them in the standard. The cross section of this tube is shown in Fig. e. One half of the tube is cast with a rack F, which is offset or located outside the circle of the tube, and at this point a long slot o. is made in the inner tube E, by which means the dog can extend out through the inner tube and engage with the rack. The rack is connected with one half of the tube D by an integral ange b, and the other half of the tube has a similar flange b which extends around and embraces the rack. On the opposite side one half of the tube has also a dange b2 which embraces the other half of the tube. By this means the parts can be iitted into the exterior tube without trouble, and the tube can be separated for adjustment or repairs, and the casting of the tube is also facilitated, and the necessity of attaching the rack independently is avoided.
G is the dog which engages with the rack. It is pivoted at d to the inner sliding tube E, and attached to a rod H pivoted thereto back of the plane of the main pivot, whereby when the rod is drawn up the dog is drawn back out of engagement with the rack allowing the seat to be raised. At other times the weight forces the dog into engagement with the rack and holds the seat elevated.
K is a lifting ring located directly under the seat and encircling the top of the tube E, by which means it can be reached and operated from any side. It is provided with a web or bearing h which extends downward and passes bodily from side to side through slots of the tube E. It has in the center a hub or boss 7c, through which passes the upper end of the rod H that operates the dog, the upper end of the rod having a shoulder Z which holds the parts together. It will be seen that by raising the lifting ring from any side the rod H will be drawn up disengaging the dog from the rack and allowing the seat to be lowered, and by dropping it again its weight, together with the weight of the other parts, forces the dog out again into engagement with the rack.
L is the bearing attached to the under side of the seat by means of screws or otherwise, and provided with a tubular shank m which extends down over the top of the main tube. By this means the bearing can be turned freely on the upper end of the tube E, carrying the seat with it, and independently ofthe adjusting mechanism. The lifting ring is provided with a band n which slides up and down on this tubular shank m, said band holding the lifting ring in position and preventing it from cramping when drawn up from one side. On top of tube E and over the bearing L is a loose ring p secured in place by a pin fr, which passes through the top of the tube. By this means the parts can be readily disconnected. By the construction above described the bearing L is fitted loosely around the tube and revolves free, by which means the seat can turn independently of the standard or any of the supporting parts.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
The combination, with the standard7 of the exterior tube made in tWo sections D Dslotted and provided with a rack F offset from the tube, an interior tube E sliding in the other, a dog G pivoted to the interior tube and passing through its slot to engage with the rack, a rod H pivoted to the dog, a lifting ring K attached to the upper end of the rod, a bearing L attached to the seat and provided with a tubular shank m, a band 'n ot' the lifting ring sliding on said shank, a loose ring p on the tubeE above the bearing, and a pin fr connecting said loose ring,r with the tube, as and for the pnrposespeeied.
In Witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
JOSEPH R. PEARTREE.
