' -"ni.nc'rnic naNn-Mmnoa Application filed I anuary 7,

To allwhomitmay concern: j

Be it known that I, JOHN A. Pn'rnm, a citizen of the United States, residing :at i New Haven, inthecounty of New Haven and State of Connecticut, have invented a new and useful Improvement in Electric' Hand-Mirrors; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings'constitute' part of this application, and represent, in

Figure l a view in front elevation of one form which my improved electric handcertain details ofconstruction as will be hereinafter described and pointed out in the claims.

In carrying out my invention asherein shown, I employ a circular mirrorlate 2 the beveled edge of which is inserte into a v tube-like binding-ring 3 which in turn is set into the open front of a circular, shallow, cup-like mirror back 4 provided with a tubular handle '5 the upper end of which is cut away-in front to .form' a deep recess 6 adjacent to the center of the lower edge of the mirror-plate 2, to receive the reflector -7 the inclined bottom of which is formed with a threaded socket 8 for the reception of a small incandescent lamp bulb 9 which is slightly tilted forward from the vertical plane of the mirror. The mirror-back 4 is located in the plane of its tubular handle 5, and the lower edge ofthe mirror-plate 2 located entirely above the upper edge of the recess 6 and the reflector 7 which latter- -is located so far back in the recess 6 in'the front of the handle 5, as torpermit the lamp to be protected against injury and to shade" I the mirror into which the lamp, when so located, cannot directly shine.

The battery 10.is held in place by a removable cap 13, provided, as shown, in its upper 3 edge with two bayonet joint notches 14; lo- 1 cated diametricallyopposite .eachother and arranged to co act with locking-lugs, 15'

By reversing the screw 16, the spring 18 is allowed to assert itself and break the contact between the points 11 and 12, thus extinguishing the j lamp.
