T ctZZ whom it may concern.-
Be it known that 1, CHARLES C. HARTUNG, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Prismatic Rolled Sheet-Glass, of
. which the following is a full, clear, and exact description, such as will enable others skilled in the. art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which I Figure 1 is a faceview of a portion of a sheet of my improved prismatic glass. Fig. 2 is an edge elevational view thereof. Fig. 3 is a sectional'view on line 3 3, Fig. 1. Fig. 4 is an enlarged sectional view on line 4: 4, Fig. 1. Fig. 5 is an enlarged sectional view on line 5 5, Fig. 1, showing the shoulders of the same height and the change in the angle of the inclined faces. Fig. 6 is a Similar view showing the shoulders of different heights, resulting from maintaining a given angle throughout the inclined faces. Fig. 7 is a sectional view illustrating a slightly-modified form.
This invention relates to a new and useful improvement in sheet-glass of the prismatic type, the object being to provide one or both faces of a sheet of rolled glass with series of eccentrically-arranged inclinations, said inclinations being arranged in serpentine form to diffuse the light to a greater extent. So far as I am aware no prismatic sheet-glass has ever before been rolled, nor have the inclined faces of prismatic glass been arranged in serpentine form and eccentric with respect to each other. The advantage of rolling prismatic glass in sheet form is that the joining of small sections is dispensed with, in addition to which a sheet may be out in any desired manner to fit a given-sized opening.
My invention is embodied in the relative arrangement and form of the prismatic faces as hereinafter described, and particularly set forth in the claims? Another feature of the invention resides in swelling the inclined faces or shoulders therebetween, depending upon the manner in which the forming or shaping device is 9. Serial No. 731,607. (N0 model.)
made, thus insuring a greater diffusion of transmitted rays of light.
In the drawings, A indicates the body of a sheet of glass on one face of which is arranged a series of ratchet-like ribs or projections 13, said ribs being shown as having inclinedfaces b and vertical shoulders b between. It will be understood, however, that thisv special form of rib ,may be changedthat is, the vertical shoulder may be dispensed with and made inclined instead-and, further, that instead of the'rib terminating in an apex a flat portion may beleft at the surface, when the structure might then be more properly described as having grooves instead of projections. Ribs B, as shown in Fig. 1, are arranged in curvilinear form on the surface of the sheet of glass, the curved lines thereof being eccentric to each other. The curved lines embraced within the bracket (1 are all described from different centers with the same radii, so that each line, as the top and base lines of each rib, is eccentric to the other line or lines of the same rib and also to the corresponding lines of the other ribs, while those comprehended within the bracket 0/ are likewise described from centers and with the same radii, which, however, may be greater or less than that employed with relation to the curves embraced by the bracket a. Two curved lines having the same radii, but described from different centers, will form a crescent if continued a sufficient distance. I make this statement merely to illustrate the fact that curved lines having the same radii and sometimes with different radii if struck from different centers will not at any point be parallel with each other, and I take advantage of this in the formation of my prismatic glass to accomplish a greater diffusion of transmitted rays of light.
In Fig. 4 I have shown an enlarged sectional view through a point in the sheet of glass where the apices of two ribs are most widely separated from each other, while in Fig. 5 I have shown an enlarged sectional view through apoint on the sheet of glass marked line 5 5, Fig. 1, where the apices of two ribs most nearly approach each other. Assuming that the vertical faces I) are the same height throughout, it follows that if the angle of the inclined face on the line 44: is any given degree-say fifteen degrees-that when said vertical faces are placed at the same height nearer together a line drawn from the top of one to the bottom of the other will exhibit a greater inclination or an increased angularity, depending upon the amount of such approach. A sheet of glass made with its vertical faces Z) in curved lines, substantially as shown in Fig. 1, will if said shoulders are the same height throughout exhibit a diference in the inclination of the faces between said shoulders, the angle of such inclination gradually increasing from a point wherein two shoulders are most widely separated to a point where said two shoulders most nearly approach each other, resulting by such change of inclination in producing wavy lines in the inclined faces, the crowns of which are approximately at points between the nearest approach of any two vertical faces or shoulders to each other. On the other hand, as-
suining that the degree of inclination of all of the faces 0 is maintained throughout, the result of this will be the production of a wavy line along the apex of each rib-that is, the vertical face I) will be highest where the distance is greatest between any two shoulders and the height of said vertical face will be less at any point where any two of said shoulders most nearly approach each other.
Havin g thus described my invention, what I claim, and desire to secure by Letters Patent, is
1. As a new article of manufacture, a sheet of glass formed with shoulders and inclined faces arranged in serpentine form and eccentrio with respect to each other, the degrees of inclination of said faces varying from a point where said shoulders are most widely separated, to a point where said shoulders most nearly approach each other; substantially as described.
2. As a new article of manufacture, a sheet of glass provided with serpentine ribs on its faces, which are eccentric with respect to each other, at least one of the faces of said ribs being inclined, the height of said ribs varying from a point where the ribs are most widely separated to a point where they most nearly approach each other; substantially as described.
In testimony whereof I hereunto affix my signature, in the presence of two Witnesses, this 13th day of September, 1809.
CHARLES C. HARTUNG.
