Devices for Securing Glasses in Place, of

- which the following is a specification.

This invention relates to devices for causing either the adherence of a transparent glass-plate, or a mirror to any object to which it is desired to ap ly' the same, and primarily is intended to he secured by suction to a window-pane, which on account of the moisture of the ,inner air deposited thereon is apt to be occluded by a film'or covered by frost.

By the use of my invention an air-tight space between two opposing surfaces is pro vided, so that the hygrometric condition of the atmosphere in a room, car, or will not cause a deposit on the window.

My invention is useful in Pullman cars, or the state-rooms of steamers, and in the cabs of locomotives and street-cars, to enable the engineer or motorman to obtain a clear view of the objects which he is passing. Furthermore, it may be em loyed as a holder for mirrors for use in siiaving, comprising, as it does, a simple suction-device adapted to be held by atmos heric pressure to any smooth'surface to wiich it may be ap lied.

n the accompanying drawings, Figure 1 is a perspective view of my improvement applied to a window-pane. Fig. 2 is a trans verse vertical section of the same.

Referring to the drawings, the numeral 5 designates a glass-plate which may be either a mirror, a lens or other substitute therefor,

- a. g. a transparent glass said glass being of any desired shape, although shown of circular form.

Designated by 6 is a holder or carrier for a glass, mirror, or other device of similar nature, which is preferably'constructed of rubber or analo ous material for reasons hereinafter stated andcorresponds in shape to that of glass 5. In this carrier is formed a groove 7 in which the plate 5 is fitted at its edge as illustrated in Fig. 2, and below the other space signed for use as a oint where said late 5 is secured'the carrier I is formed with a c amber 8, the wall of which is preferably inclined at 9, and has at its lower end a rabbet 10.

When employed as a vision-glass my improved deviee is readily secured to the pane 12 of .a car or other window, and owing to the flexible nature of. the frame or" carrier 6 by compressing the same the air'is exhausted from the chamber 8 thereof, and the atmosheric pressure will cause said carrier to adliere closely to the windowane or other object upon which it is positioned. in other words the chamber 8 acts as a suction-space and the device is held by atmospheric-pressure to the object towhic'h it is applied after the air has been exhausted from said chamber 8. As will be apparent the device may be readily applied to a window-pane of a Pullman-car, room, or other construction, and will prevent frosting of said windowpane or of the adherence of the moisture of the inner air therero. So too, it is most convenient as a holder for mirrors or lookingglasses, and may be ap wall of a room, or ot er compartment and thus be useful. as a shaving glass. 'In either construction employed it will be seen that an air-tight space is rovided, and when emloyed as a vision-g ass the moisture of the inner air will not reach the window, whereb a clear view through the same is assure Furthermore, when used as a shaving-glass oras a mirror or for other purposes the device will firmly be held in place by atmospheric-pressure, and will thus afford a convenient means for travelers and others in affording a convenient device for various purposes,

My invention is not limited to the form of the carrier, nor to the particular material of which it may be com osed, provided said material has the quali cations necessary to enable the structure to be secured in the manner described, and while primarily devision-plate or glass for Window-panes, is not necessarily limited to such use.

Having thus described the invention, what I claim is '1. The combination, with a yieldable carlied by suction to the 886,273 rier normally open at both ends, of a plate said rubber-frame secured in one open end of said carrier,the an object.
