JAMES G. PENNYOUIOK, OF NEYV YORK, N. Y.
WINDOW-GLASS.
SPECIFICATION forming part of Letters Patent No. 312,290, dated February 17, 1885.
(Specimens) T 0 all whom it may concern:
Be it known that I, J nuns G. PENNYOUIOK, a citizen of Great Britain, at present residing in New York city, State of New York, have invent-ed a new and useful Improvement in XVindow-Glass, of which the following is a specification.
The nature of my invention consists in the construction of window-glass,whereby the reflection of the light into the room is considerably increased without increasing the size of the window.
In the accompanying dra\vings,Figurc I represents a front view of my improved windowglass. Fig. II is a side view of the same.
A represents my improved window-glass, one side of which is made perfectly straight, and the other side is provided with ribs or projections at. These ribs or projections a extend only within one-half of an inch or more of the edges of the surface, leaving a space, 0, on top, bottom, and sides of the sheet of glass, flat or straight on both sides, for fastening the same into the window-frame in the usual manner. The ribs or projections a are made triangular in section, the top surfaces, 2, of each being parallel to each other,and nearly square with the body of the glass sheet, and the front surfaces, 3, being diagonal, running from the outer edge of the top surface, 2, to the inner edge of the surface of the lower rib, or to the body of the glass sheet A. By this construction of window-glass about double the quan tity of reflection or illumination of the plain window-glass of same size will be obtained, and will obviate the necessity of ground or opaque glass (whereby the admission of light is still more obstructed) in places where it is not desirable to have a view into the room from the outside.
I am aware that it is not broadly new to providewindowglass with reflecting-ridges; but the ridges heretofore employed have been formed with similarlyinclined or angular side surfaces. The effect of ridges thus formed is to concentrate the light at the point of meeting of the angles. My improvement comprehends only a ridge one of whose sides is at practically a right angle to the body of the glass,while the other side is inclined at an angle approximating forty -iive degrees. The effect of this form of reflector is to thoroughly diffuse the light, which first silvers the plane surface of the ridge and is then reflected from the inclined surface. Thus I obtain a mirror-like reflection and diffusion of light unattainable with a reflector of inverted pyramidal form.
Vhat I claim as inyinvention, and desire to secure by Letters Patent, is
As a new article of manufacture, a window glass one side of which has a plane surface, while the opposite side is formed with a series of ribs, each of which is formed on one side with a surface at practically a right angle to the body of the glass, while its opposite side is inclined at less than a right angle, substantially as set forth.
