OPERA OR SCH 00L CHAIR.

SPECIFICATION forming part of Letters Patent No. 356,222, dated January 18, 1887.

Application filed April 17, 1886. Serial No. 109,212. (No model.) i

invented certain new and useful Improvements in Opera or School 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 and figures of reference marked thereon, which form a part" of this specification, in which- Figure 1 is a side elevation of my chair. Fig. 2 is an enlarged view of the same with parts broken away. Fig. 3 is a sectional view. Fig. 4 is a perspective View of the top of the pedestal with the seat removed.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to opera or school chairs; and it consists in the improved construction of parts of the same, as hereinafter more fully described and claimed.

A represents the pedestal, the upper portion of which is shaped somewhat like a hollow cone, as shown in the drawings. The edge a a of this pedestal is slightly curved,- and receives the weight of the straight seatbar B. To this seat-bar is rigidly secured the metal casting 0, containing the socket D, fitting the edge of the pedestal. On the opposite side of the seat is a seat-bar similar in all respects to the bar B, having the metal casting 0, provided with a socket, D. By means of these sockets D D and bolts F F the seat-bars B B are secured to the pedestal in such. a way as to allow them to rock slightly on the springrubbers E E,placed in the sockets D D, a small portion of the pedestal A being cut away under the metal castings O to admit them. The seat-bars B B are provided near their rear extremities with the flanges G G, to which the seat-frame H is pivoted, by which arrangement the seat may be raised and dropped.

At the forward extremities of the seat-bars B B are the sockets I I, to receive the rubber stops K K, thus making the drop of the seat noiseless.

The seat-bars may be constructed of a single piece bent in the shape of a horseshoe, the

seat-back being rigidly secured to the bent portion. In the construction shown the back L is secured to the rear ends of the seat-bars.

To the under side of the seat may be attached a support for a hat, the crown of which, when the seat is dropped, is in the'hollow of the pedestal.

Instead of the upper portion of the pedestal A being as described, it may consist of a tripod'having a circular band of metal extending around and being rigidlysecured to each of the arms of the tripod at its upper extremity. This band of metal has a slight upward curve,

which enables the straight bars B B to rock I upon it. g

I am aware that the rectangular bases of barbers chairs have been provided at their top with rocking surfaces and have had seats pivoted to said base.

not claim.

Having described my invention, I. claim as,

follows:

1.. The combination,with a pedestal apart of which is provided with upwardly curving edges, of seat-bars having portions engaging the curved edges of the pedestal and pivoted to the pedestal, said seat-bars being solely supported by said pedestal and engaging the'same upon the curved edges, and a seat pivoted to said, seat-bars, substantially as described.

2. The combination, with a pedestal the upper part of which is provided with up wardlycurving edges, of seat-bars having straight portions engaging the said curvededges and pivoted to the pedestal below the curved edges of the same, the point of pivoting being forward of the center of the said seat-bars, and a seatframe pivoted to said seat-bars, substantially as described.

3. The combination,with a pedestal the upper portion of which is provided with upwardly-curving edges, of seat-bars resting on said curved edges and pivoted to the pedestal below the same, the point of pivoting being forward of the center portion of the seat-bars,

of a seat pivoted to the rearward portions of 4. The combination, with a pedestal the up per part of which is provided with upwardlycurving edges and provided with seat-bars en- This construction I do a rubber strip interposed between the said seat-bars and pedestal, and a seat pivoted to said seatbars at their rear ends and extending forward and resting upon the forward ends of [5 the same, substantially as described.

6. The combination, with a hollow-topped pedestal, of seat-bars attached thereto and a seat pivoted at its rear to said seat-bars and extending forward over the top of the pedestal,

the said seat being provided with a hat-sup- 20 port above the concavity of the pedestal, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
