ISIDORE MARGARETTEN AND MORRIS GREENh-AN, OF NEW YORK, N. Y.

FLASH-LIGHT OPERA GLASS.

Application led January 26, 1923.

To all whom t may concern.'

Be it known that we, Isinonn MARGARET- 'rEN and Monnrs GREENMAN, citizens of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Flash-Light lOpera i Glasses, of which the following is a specification.

This invention relates generally to operaw glasses, having more particular reference to a combination opera-glass and flashlight, the invention having for an object to provide a type of opera-glass which is used in the ordinary manner when desired, and which can be utilized to illuminate a program so that the latter can be read during the course of a performance, when the lights are lowered.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings and to the appended claim in which the various novel features of the invention are more particularly set forth.

Fig. l of the drawing is a part longitudinal elevation and part sectional view of a pair of operaeglasses having the invention embodied therein.

Fig. 2 is a front view thereof.

As here embodied our improved operaglasses comprise the main casing elements lO which carry the usual front lenses il and may be of ordinary shape.

The frame of the opera-glasses comprises the transverse members fixed to the front and rear of the casings 10 and each made up` of two sections the respective sections of the front frame members being indicated at 26, 26 and the respective settions'of the rear frame members being indicated at 27, 27. rlhe frame members 26, 2'? are forked at their inner ends as at 26a, 27a and frictionally straddle the inner ends of the members 26', 27, the inner ends of all four frame members being suitably apertured to receive freely the diminished ends such as 28 of a post 30 having a threaded socket 31 entering from the rear end thereof.

Into this socket projects the threaded forward end of a hollow rod 32 whose rear end is engaged with a sectionaltransverse bar Serial No. 614,985.

made up of two

sections

33, 38 the section 33 being formed with a forked end 33a adapted to frictionally straddle the end of the other section. The outer ends of this rear bar having mounted thereon the lens rings 35 which carry the usual rear lenses, and have projecting therefrom the tubes 36 which engage in the usual manner in the casing elements l0.

Upon the post 30 is mounted a thumb and finger wheel 38 by rotation of which the lenses are advanced.. T he post 3() is form-ed with an inturned annular flange near its forward end which grips a flashlight 5l, the latter extending freely into the hollow rod 32. Into the forward end of the post 30 is screwed a short tube V52 which has a lens 515 at its forward end adjacent which is a knurled flange 54 and adapted to be gripped to rotate the tube to vary the focal point of the light. One terminal of the flashlight battery connects to a stud 55 on the side of the flashlight, while the other connects` to a spring contact 56 normally engaging said stud. rlhis spring extends beyond the forward end of the flashlight and is adapted to be engaged by the inwardly flared rear end 52l of the tube 52 to be lifted from engagement with the stud 55. As will be apparent, as soon as the tube 52 is moved outward to focus the light4 on the desired object, the spring contact 56 engages the Contact 55 and so closes the flashlight circuit.

l-laving thus described our invention what we claim as new and desire to protect by Letters Patent of the United States is as follows:

A device of the class desfribed comprising a pair of casings adapted to carry front lenses, an adjusta le element adapted to carry rear lenses, said element including a hollow externally screw threaded rod, a sleeve swiveled between the said front and rear connecting` members into which said rod is threaded, and a flashlight engaged in said rod and sleeve, said flashlight being g 1ipped by said sleeve and extending freely into said rod.

ln testimony whereof we have affixed our signatures.
