WINDOW-REFLECTO R.

SPECIFICATION forming part of Letters Patent No. 248,492, dated October 18, 1881. Application filed July 20, 1881. (Model) To all whom it may concern:

Be it known that I, ANDREW GUSTAF MOODHE, of Stillwater, in the county of Washington and State of Minnesota, have invented certain useful Improvements in Window-Beflectors, of which the following is a specification.

The object of my-invention is to provide a new and improved window reflector or mirror which can be adjusted in its inclination to the window and in its inclination to the vertical plane.

The invention consists in a window-reflector composed of two mirrors, each pivoted at the middle of the ad oining ends to a plate in which a small shaft is loosely mounted, having a hand-wheel on one end and a pinion at the other end, which pinion engages with two curved racks pivoted to the inner sides of the mirror, whereby the inclination or angle of these two mirrors will bevaried by rotating the pinion. The lower ends of the mirrors are connected by small wires with a trans verse strip pivoted to the lower end of the plate to which the mirrors are pivoted, and provided with a small shaft with a hand-wheel at the end for changing the vertical inclination of the mirrors, as will be more fully described hereinafter.

In the accompanying drawings, Figure l is a 'plan view of the under side of my improved window-reflector. Fig. 2 is a rear elevation of the same.

Similar letters of reference indicate corresponding parts.

The mirrors A A are hinged to strips A pivoted at the middle of one edge to a plate, B, in the middle of which a rod or shaft, 0, is loosely mounted, and has a small hand-wheel, D, at the outer end, and a pinion, E, at the inner end. This pinion engages with the curved racks F F, pivoted to the inner surfaces of the mirrors A. One rack is above the pinion and the other below it, and the racks are held on the pinion by the clips G, of which one is arranged at the end of each rack, and surrounds the opposite rack. A strip, H, is pivoted to the lower end of the plate B, and the ends of this strip are connected by links J with the lower corners of the mirrors A. The strip H is provided with a handle-rod, K, with a hand-wheel, L, at the end.

The operation is as follows: The reflector is fastened on a suitable frame outside of the window in such a manner that the pivoted ends of the mirrors are nearest the window. If the angle of inclination to the window and to each other is to be changed, the hand-wheel D is turned, thereby turningthe pinion E and drawing the free end of the mirrors to each other, or separating them, according to the direction in which the wheel D is turned. The rack and pinion lock the several parts in any desired position. Thus if the person looking into the. reflector wishes to see objects at a considerable distance from the same the outer ends of the mirrors are drawn together, and if objects near the reflector are to be viewed the mirrors are to be separated. The inclination of the mirrors to the vertical plane must be varied accordingly as objects a' less or greater distance from the ground are to be viewed, for in the former case the mirrors must be inclined downward toward each other, and must approach the vertical position as the object is a greater distance from the ground. These adjustments can be accomplished by turning the hand-wheel L, for thereby the strip H swings on its pivot, and consequently draws the lower corners of the mirrors A toward each other, whereby the mirrors are inclined, the same turning on theirpivots on the plate B.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. In a window mirror, the combination, with the mirrors A and plate B, of the plates A, the shaft 0, the pivoted racks F, and the shaft (J, provided with the pinion E at its up per end, and hand-wheel D at its lower end, substantially as and t'orthe purpose set forth.

2. In a window-reflector, the combination, with the mirrors A, pivoted at theirlower ends to the plate B, and the pinion E on the upper end of the shaft 0, of the racks F, provided with the clips Gr, substantially as and for the purpose set forth.

, 3. In a window-reflector, the combination, with the mirrors A A, pivoted to the plate B, of the strip H,pivoted to the plate B, the links J J, attached to the ends of the strip H, and to the lower adjoining corners of the mirrors, the shaft K, and the hand-wheel or equivalent, L, substantially as herein shown and described, and for the purpose set forth.

ANDREW GUSTAF MOODHE.
