IVHRHOR ATTACHMENT FOR THEATER-CHAIRS.

SPECIFLCATION forming part of Letters Patent No. 700,975, dated May 27, 1902.

Application filed January 30,1902. Serial No. 91,866. (No model.)

To (tZZ whom it may concern:

Beit known that I, HATTIE AGUSTA NORTH- RIDGE, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Mirror Attachments for Theater-Chairs, of which the following is a specification.-

All theater-goers feel the annoyance from the hat-wear, and while it has been proposed to provide mirror-brackets adj ustabie on the backs of chairs for holding the hats and observing persons in different parts of the house in rear of the occupant of the seat, so far as I know and can find there is not such a convenience in use in any theater in the country, although such a convenience is admitted to be a desideratum felt by every occupant of a seat in a theater.

Myimprovement is directed to the provision of such a convenience designed with special reference to its simple construction, and particularly in the provision of friction-joints whereby the hat-bracketis held in the desired position and the mirror when used as such held in the position which the occupant desires for adjusting her hat or for seeing persons in the rear of her seat in any part of the house and in rendering the device safe as a fixture on the back of the chair. In these particulars my improvement will be set out in the claim appended hereto in connection with the accompanying drawings, in which Figure 1 shows my mirrored hat-holding attachment in its folded position against the back of the chair. Fig. 2 is a side view of the same as swung out from the back of'the chair for holding a hat or for observation. Fig. 3 shows in side view, enlarged, the frictional coupling which secures the mirrored frame to the curved arm. Fig. 4 is a top view of the same. Fig. 5 shows such frictional coupling in vertical and horizontal sections. Fig. 6 is a top view of the frictional coupling of the arm with the chair-back, and Fig. 7 is a vertical section of the same.

A bent or curved arm 1 pivotally connects and carries at one end a mirrored frame 2 and at its other end is pivotally connected to the back of the chair, and my improvement resides in these connections, whereby the arm and the mirror are free to be set in any position and held by the frictional functions of their respective pivotal connections. The con nection of thearm to the chair-back is such as to provide freedom for the horizontal swinging of the arm and for holding it by friction of its joint connection in folded position against the back of the chair or in its outward-swing positions. At this connection the curved arm has a downward-return branch 3, which terminates in a short angle end 4, by which the arm is secured by a keeper 5, fastened to the chair-back. This keeper is of sheet metal and engages the return-arm branch 3 like a strap and forms a tube, within which the arm is held and secured by its short angle end. The keeper is U shape in cross-section, its edges 6 being turned outward from each other to form. clips, which engage the edges of an opening in a plate 7, which is secured to the back of the chair, and thereby secures the keeper to the plate. A plate-spring 8 is set in the opening in the plate and forms the back of the keeper and africtional bearing or binder against the return-arm branch, the bends of which prevent the removal of the arm from the keeper, while allowing it to freely swing in frictional contact with the plate-spring to hold the arm in folded position against the chair-back or when swung out to hold the hat. At its other end the upward-standing end of the curved arm has an annular groove 9, and a tip tubular coupling or socket-stem 10 is fitted upon the grooved end andby protuberances or shoulders 11, formed on its inner walls, engage the groove, and thereby secures the socket-tip or coupling to the arm and gives freedom for the coupling to turn or swivel upon and as a section of the arm. The upper end of the socket-stem coupling is bifurcated to form jaws 12 to receive a bracket projection 13, secured to the back of the mirror-frame, and to which bracket projection the socket-stem is joined by a rivet 14 to allow a vertical swinging movement of the mirrored frame. This rivet-joint, it.will'be noted, clamps the jaws of the socket-coupling upon the bracket projection to give sufficient friction to the clamped parts to hold the mirror in whatever position it may be set with a vertical movement, while the groove-and-shoulder engagement of the coupling-socket stem with the curved arm gives sufficient friction to hold the mirror when turned to either side or in any positionfor observation by the occupant of the chair of persons in the rear thereof. This construction of the joint connections gives the advantage of holding the arm and the mirror in their set positions solely by friction and avoids clamp-screws, which would permit the removal of the parts, and the cost of ball-and-socket joints for the mirror. The attachment can be secured to or near the edge of the chair-back.

Looking at Fig. 5 it will be noted that the interior locking of the coupling stem or tip upon the arm is by indenting the outer walls of the tip to form integral protuberances on the interior of the walls of the stem at points coincident with the groove of the arm, whereby the adjustment of the stem is maintained and the stem rendered inseparable from the arm, while the rivet. connection of the mirror with the stem gives freedom for the adjustment of the mirror and renders it inseparable from the stem. c This inseparable feature of thejoints is a matter of importance in the use of mirror attachments for theater-chairs,

which with screw-fastenings could be easily removed and lost.

I claim- An inseparable mirror attachment for theater-chairs and in combination with an arm pivotally mounted on the back of the chair to swing horizontally and having an annular groove at its other end, a coupling stem or tip having its lower end tubular and formed with integral shoulders or protuberances on its interior walls frictionally engaging or binding the groove of the arm to automatically maintain the adjustment of said stem, and a mirror-frame pivotally connected to the upper end of said coupling stem or tip, the pivot having its ends upset to produce friction whereby the adjustment of the glass is main* tained and the stem and the mirror rendered inseparable from each other and from the arm,

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