RUDOLPH M. HUNTER, 0F PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO EVA M. FLORENCE, on NEW YORK, N. Y.

CHAIR FOR THEATRICAL OR OTHER PURPOSES.

SPECIFICATION forming part of Letters Patent No. 485,277, dated November 1, 1892.

Application filed April 27, 1892. Serial No. 430,912. (No model.)

To all whom, it may concern.-

Be it known that I, RUDOLPH M. HUNTER, a citizen of the United States, and aresident of the city and county of Philadelphia and State of Pennsylvania, have invented an Improvement in Chairs for Theatrical or other Purposes, of which the following is a specification.

My invention has reference to chairs for theatrical or other purposes; and it consists of certain improvements, which are fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof.

This specification (Case No. 220) is for a structure of chair especially adapted to theatrical purposes, but may be employed in asylums or other places where it is necessary to temporarily hold insane or obstreperous persons in subjection.

The object of my invention is to provide a chair which shall have one or more movable portions adapted to secure a person sitting or reclining upon a chair or article of furniture firmly to it when desired, and in practice the said means are so combined with the chair or article of furniture that the act of the person sitting or reclining upon it automatically puts the devices into operation to secure him firmly in position and lock the parts, so that it is impossible for him to liberate himself. The article of furniture shown herein is a chair, and is exceedingly Well adapted for theatrical purposes of the sensational kind; but. it is evident that its use may be extended to insane asylums or other places where it becomes necessary at times to hold in subjection dangerous persons. The construction is such that if a person is suddenly thrust in the chair when its parts are set for operation the act of sitting or reclining upon it will instantly liberate the mechanism and cause him to be clasped about the upper parts of the arms adjacent to the shoulders and over the limbs, so that no movement of the body would extricate him. Once these parts are thrown or moved they are automatically locked, and it is necessary for a second party to manipulate the mechanism before the person secured in the chair can be liberated.

Referring to the drawings, Figure 1 is a front elevation of my improved chair. Fig. 2 is a side elevation of same, and Fig. 3 is a perspective skeleton view showing the operative parts removed from the chair.

A is the chair proper, and may be of any suitable design and provided with any artistic style of feet.

B represents the arms of the chair,and may be formed in any manner.

0 O are two curved clam ping-arms adapted to clasp over the legs or knees of the persons sitting upon the chair and are secured to the ends of rock-shafts D, preferably secured through the arms B and the back of the chair. Springs J, acting upon cross-arms c at the ends of the shafts D, may be employed to cause the arms 0 to be suddenly thrown over upon the person upon the liberation of the cross-arms c.

In Fig. l the arms 0 are shown in dotted lines when thrown back, and the fulllines indicate the position of these arms when holding the person in the chair. When these clamping arms are thrown into the position shown, the arms 0 snap back of the pawls E, which may be pressed down by springs e, and thus lock them in such position and prevent their movement until the arms 0 are liberated from the said pawls E. The springs J may be of any strength desired to make the rapidity of movement greater or less.

F F are two pivot pawls secured to theback of the chair and preferably connected by aspring G. When the clamping-arms C are turned up to the dotted position shown in Fig. 1, the lower ends of the cross-arms c are caught upon the edges f of the pawls F and maintained in such position by the lock 2', which is thrust between the pawls.

II is a movable seat and is sustained upon springs 7L. lhis seat is provided with a downwardly-extendin g part H, which is pivoted to an arm I, hinged at one end to the chair and connecting at the other end with the lock 2'. It is evident that when the person sits upon the movable seat Hit is depressed. Thelock i is thrust downward, liberating the pawls F. The pawls F are drawn together by the spring G and the cross-arms c are liberated permitting the shaft D to rotate, so as to throw down the arm 0.

In Fig. 3 we have shown the pawlsF F and; lock in the lockingspositions to better illusprovided with cross-arms M and-also --wi-th springs L, which are adapted to normally throw the clamps K into position to grasp the shoulders or upper parts of the arms of" the occupant of the seat, as shown in Fig. 2. When these clamps K are turned back, one. end of each of the cross-arms M is caught by the pawls N and is held there by the pawls F, the extensions G of which" prevent the pawls N being thrust back by the action of the springs L. The instant, however,.the lock '6 is drawn down the action ofthe springs L is sufficient to cause the cross-arms M'to fly out of connection with the pawls N and each to make a slight. revolution, bringing the other end of the arms 'M into a locking. position.

with the pawls N, as shown in Fig. 3, thereby locking the clamps K upon the person.

vSprings n may be employed to normally hold the locking-pawls N in position. Each ofthe clamps K is operated in the same manner. It will thus be seen that all of the mechanism for holding. the person-in the chair is .controlled automatically from the same part, so that it is simply necessary to thrust the. .pe-r-.

son into the chair to instantly bring thepart-s I into-operation to secure him.

his quite evident that the various details may be greatly modified and yet accomplish precisely the same general results, and-it is also evident that the. particular means .em: ployed for holding the person .inthe chair-or article of furniture may be greatly modified without departing from the principleof my in-.

vention, which,-broadly construed, embodies; I suitable automatic mechanism for "looking apersonin position in a chair or art-icleoffu'rr. niture, preferably through the weight or. movement of the person in *the .act of sitting down or reclining upon the chairorarticle of furniture. improvement is especially illustrated in connection with a chair the configuration of .the :article offurniture may begreatly varied, so as to make the chair resemble. :otherarticles of furniture-such, for instance,-as:a lo.unge.-

In all cases, however, the general principle.

of securingthe-person in .position upon the .article of furniture'by themovement or.

weight of the person. himself bymeans of movablepartswould be the same.

Broadly considered, my invention compres hends any suitable fixedor practically-stationary frame provided with the movable clamping devices,substantially asherein set out, whereby the person is clamped or held to the frame. The-frame may have any con figurationdesired. Therefore when I-use the words article offurniture in the claims it isusedwith theabove understanding. I therefore do not limit myself to the details of I It is also evident that while my construction herein set out, as the same may be greatly modified without: departing from the spirit of the invention.
