WILIBUR W. WOLARY, OF WASHINGTON, IOWA. V

OPERA-CHAIR.

Application filed April 20, 1918.

To all whom it may concern:

Be it known that I, l/VILBUR W. WOLARY, a citizen of the United States, residing at Vashington, in the county of WVashington and State of Iowa, have invented certain new and useful Improvements in Opera-- Chairs, of which the following is a specification.

My invention relates to an improved opera-chair, and the fundamental object of this invention is to provide a ready means of exit to the rear of the house rather than to the side aisles as at present, the consequence of which is that a theater, operahouse, church or otherpublic assembly hall can be quickly emptied at all times, and especially in an emergency without unnecessary jostling, and above all endangering the lives of the people, as it avoids crowding and congesting into the ordinary aisles, of which there are usually only a few, and which must ordinarily take care of the entire audience.

This invention comprises a pedestal, an arm pivotally supported thereon, with a back and seat connected to the arm, onerof which is pivoted, with means for fastening the seat when down against turning on the pedestal; the invention further consists in details which may or may not necessarily go with the foregoing to make a complete operative and successful construction.

In the accompanying drawings Figure 1 is a view in side elevation showing the seat down, in full lines, and in dotted lines showing it raised;

Fig. 2 is a front view showing the bottom of the seat when in its raised position;

Fig. 3 is a vertical sectional view;

Fig. 4: is a detached View of the side bracket;

Fig. 5 is a detached View of the pedesta plate;

Fig. 6 is a diagrammatic View showing the manner of turning the chairs to form aisles to the rear of the auditorium when the seat is raised and the occupant leaves.

A, is the pedestal which comprises a base and a hollow column in which the sleeve 1 may be shrunk or otherwise secured. On top of the pedestal a plate 2 is integrally formed. This is faced off at two edges at right-angles to each other, as shown at 4:, 4, and a thin reversible plate 5 having a hole 6 to aline with the hole 7 through the pedestal is detachably held in place at one Specification of Letters Patent.

corner by a screw 7 which extends into the This detachable plate is faced off at one edge 8 to aline with the one or the other of the edges 4 and 4: accordingly as the seat is to be turned to the right or the left; and the head of the screw 7 is also faced off at right-angles to form two sides 9 and 9 to.

afford stops to limit the quarter turn of the seat mounted thereon.

The chair comprises a seat 10 and back 11. Both are supported on a spring plate 12. The back is secured to this plate, and it has sufficient resiliency to yield more or less to pressure as the occupant of the seat leans against the back( The seat is hinged to the opposite end of the plate as at 13, and between the ends of the plate is bent to form a rest 14 for the support of the-seat some distance forward of the hinge, and beneath this rest 14 a hole 15 is formed in the plate to receive the bolt 16 which extends through the bore 6 of the pedestal and receives a nut 17 on the lower end, whereby the opera-chair is pivotally supported on the pedestal. V

A bracket 18 on the side serves to support one end of the hinge-pintle 19, and also it projects down into position to engage the side of the pedestal and prevent the chair from turning when the seat is down, and one end of it also is adapted to strike the reversible plate 5 when the seat is raised and the chair is turned.

The opera-chair may be made to turn either to the right or to the left according V to the desire of the proprietor by the way the removable plate 5 is placed, the change from right to left or vice versa being accomplished by simply reversing or turning the plate over and fastening it by the screw. Of course all are made uniformly in the same direction, but all can be turned either to the right or the left accordingly as the chair is originally adjusted and mounted.

The spring-plate which supports both the seat and the back is so constructed that it afl'ords resiliency for both and more especially the back. i

The invention is simple, composed of few parts, and can be easily and economically manufactured, but, above all, it affords a quick means of exit with ample space for each person, and absolutely precludes the possibility of crowding and congestion and the danger resulting therefrom in a hurried rush from a public building, and at all times makes the clearing of a house a matter of.

simplicity and expedition.

I claim: i

1. The combination with a pedestal, a back and seat, of a single spring-plate secured to the back and having the seat hinged thereto, said plate pivotally supported on the pedestal, and means on one of the parts to prevent the chair from turning when the seat is lowered and to prevent the seat from being lowered when the chair is turned in one direction.

2. The combination with a. pedestal, a back and seat, of a single springplate secured to the back and having the seat hinged thereto, said plate pivotally supported on the pedestal, and a single detachable device at the upper end of the pedestal forming a stop to limit the turning of the chair in either direction.

3. The combination with a pedestal, a seat and back, and a common means of support for the seat and back pivoted to the pedestal, one part of the seat being secured rigidly thereto and the other hinged, of a reversible plate having a stop thereon, which plate limits the turns of the chair to right or left according to the way it is placed on the top of the pedestal.

4. The combination with a pedestal, of a folding chair comprising back and seat, a spring-plate pivoted to the pedestal and secured to the'back and to which the seat is hinged, this plate having a rest formed therein some distance from the hinge whereby to afford a spring support to the seat as well as to the back.

5. The combination with a pedestal, of a folding chair comprising back and seat, a spring-plate pivoted to the pedestal and secured'to the back and to which the seat is hinged, this plate having a rest formed therein some distance from the hinge whereby to afford a spring support to the seat as well as to the back, a bracket on the seat aflording support for one end of the hinge 'pintle, and a stop to prevent the seat from raised position when up and the entire chair 'is' turned at right-angles.

6. The combination with a pedestal, of a folding chair comprising back and seat, a spring-plate pivoted to the pedestal and secured to the back and to which the seat is hinged, this plate having a rest formed therein some distance from the hinge whereby to afford a spring support to the seat as well as to the back, a reversible plate detacha'bly secured on the pedestal, and a screw removably fastening the latter to an integral plate on the top of the pedestal, which also serves as a stop to limit the turns of the chair in both directions.

7. The combination with a pedestal, of a folding chair comprising back and seat, a springplate pivoted to the pedestal and se cured to the back and to which the seat is hinged, this plate having a rest formed therein some distance from the hinge whereby to afford a. spring support to the seat as well as to the back, a reversible plate detachablv secured on the pedestal, a screw removably fastening the latter to an integral plate on the top of the pedestal, which also serves as a stop to limit the turns of the chair in both directions, and a bracket on the bottom of the chair which prevents the chair from being turned on the pedestal when the seat is down, and which prevents the seat from beinglowered when the chair is turned to one side.

8. The combination with a pedestal and a chair mounted to turn bodily thereon, of reversible means for regulating and confinin g the turn of the chair in a direction either to the right or the left. i

9. The combination with a pedestal and a chair comprising a back and bottom, one of which parts folds, the chair mounted to have a quarter-turn bodily on the pedestal,

of reversible means for regulating and confining the turn of the chair in a direction either to the right or the left.

In testimony whereof I affix my signature.
