FERDINAND JAEGER, OF NEW YORK, N. Y.

MIRROR.

SPECIFICATION forming part of Letters Patent No. 728,927, dated. May .26, 1903-.

Application filed March 3, 1903. Serial No. 145,943. (No model.)

To to whom, it may concern:

Be it known that I, FERDINAND JAEGER, a citizen of the United States, and a resident of New York city, (Brooklyn,) county of Kings, and State of New York, have invented certain new and useful Improvements in Mirrors, of which the following is a specification.

This invention relates to a mirror which is so constructed that it maybe rotated, together with an auxiliary mirror, upon a universal joint and will thus expose to view any part of the body the image of which is reflected into it.

In the accompanying drawings, Figure l is a front elevation of my improved mirror; Fig. 2, a side elevation thereof. Fig. 3 is a front elevation of the mirror, showingit turned sidewise; Fig. 4, a plan of Fig. 3; Fig. 5, a side view of the mirror-supporting arm; Fig. 6, a detail of the shaft, and Fig. 7 a detail of the notched disk.

The letters a (1 represent a pair of posts projecting upwardly from a common base-plate a, the whole constituting a frame. Within bearings ct of posts 0!. is free to rotate a shaft 17, which is centrally perforated, as at b, for the admission of an arm 0. This arm extends at right angles to the shaft 1) and is axially rotatable in its bearing 1 the whole thus forming a universal joint between arm 0 and posts a. In order to introduce the arm 0 into its bearing b, the shaft 1) is provided with a removable plate 5 Fig. 6, which is screwed to the shaft above hearing I), Fig. 4.

The arm 0 is provided above shaft 1) with a shoulder c, which rests upon the shaft and prevents a downward displacement of the arm, though permitting its free rotation. Above the shoulder c the arm 0 forms a loop or eye 0 to which is pivotally secured a main reflector or mirror d by pintle d. Beyond the shoulder c the arm 0 extends first backward to clear the reflector d, then upward, and then forward and downward, so that its upper end extends centrally above the main reflector (Z. This upper end is bent into a looped bearing 0 for the pintle e of a pivoted auxiliary reflector e.

The lower end of the arm 0, which projects through the shaft b, carries a counterweight f, that counterbalances the combined weights of the main reflector and the auxiliary reflector.

The reflectors d 6 may be set at any desired inclination to the arm a, and by partly rotating shaft 1) in its bearings a both mirrors are moved in a vertical plane, so that the image of any part of the head or body introduced between them is reflected by mirror 8 into mirror d. By partly rotating arm a in its bearing 13 both mirrors will be turned sidewise, Figs. 3 and 4., so that the sides of the head or body may be freely reflected. Thus it will be seen that by a proper manipulation of the apparatus all parts of the body may be freely inspected without changing the position or distorting the figure, the weight f retaining the mirrors in any position to which they maybe set.

In order to lock the shaft b to the frame, and thus fix the mirrors, I mount upon a squared section b of shaft b a notched disk 9, adapted to be engaged by a detent g, pivoted to one of the posts a. The end of shaft b is, moreover, threaded, as at b, for engagement with a winged nut h, which bears against disk g and constitutes a brake by which the freedom of movement of the shaft 1) may be readily controlled. If desired, the base-plate a may support a drawer a. and the frame may be suspended from a wall by an eye a.

What I claim is- 1. A mirror composed of a stand, a perforated shaft rotatable therein, an arm axially rotatable in the shaft, and a pair of reflectors secured to the arm, substantially as specified.

2. A mirror composed of a stand, a perforated shaft rotatable therein, an arm axially rotatable in the shaft, a pair of reflectors pivoted to the arm above the shaft, and a counterweight mounted upon the arm below the shaft, substantially as specified.

3. A mirror composed of a stand, a perforated shaft rotatable therein, an arm having a shoulder that rests upon the shaft, and a pair of counterbalanced reflectors pivoted to the arm, substantially as specified.

4. A mirror composed of a stand, a-perforated shaft'rotatable therein, means for looking the shaft in position, an arm axially rotatable in the shaft, and a pair of counterbalanced reflectors pivoted to the arm, substan- 1o tially as specified.

Signed by me at New York city, (Manhattan,) New York, this 28th day of February,

FERDINAND JAEGER. WVitnesses: WILLIAM SGHULZ,
