GLASS-SIGN-LE'ITER FASTENING.

i Application filed March 4,1926, Serial m. 92,322.

My invention relates generally to glass signtletters', numerals, andthe like, and more particularly to means for'fastening said 1et= ters tov a base or background, the principalL objectsofmy invention beingto provide relatively simple" and praotiealmeans for fastening glass or porcelain sign letters to a base and which fastening means is especially designed to eliminate breakage of the sign 1 letters while the same are being secured to a base or panel.

It will be understood that letters and figures of glass, porcelain, and like brittle material are largely usedin the formation of signs and for house numbers, and when these letters, numerals and the like, are secured to a base or panel that forms the background for the sign, the seating of the fastening devices, which are usually screws or nails,

very frequently results in breakage of the frangible material from which the letters and characters are composed.

It is the purpose of'my invention to provide si n letters of glass, porcelain, and the like, with notches that are adapted to receive the fastening screws, and which notches are constructed so that when the heads of the screws enter said notches they will engage beveled or inclined faces that tend to move the screws away from the bodies of the sign letters, thereby preventing said screws or the heads thereof from exerting stresses on the letters that would tend to break or fracture the same.

With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of parts that will hereinafter be more fully described and claimed and illustrated in the 4 accompanying drawing, in which Fig. 1 is an elevational view of a sign letter that is constructed in accordance with the principles of my invention.

Fig. 2 is an enlarged elevational view of a portion of a sign letter that is notched in accordance with my invention for the recep tion of the fastening device.

Fig. 3 is an enlarged cross section taken on the line 3-3 of Fig. 1. v

Fig. 4 is a detail section of a modified form of the sign letter fastening device.

Referring by numerals'to the accompanying drawing, 10 designates the body of a letter, numeral, or like character, that is formed of glass, porcelain, or the like, and

arranged at suitable points on the edges of the'body of'isaid letter or characterare short outwardly-projecting lugs 11;

Formed the outer'portionbf eacli lug 1s an arcuate or: substantially semi-"circular" notch '12"; and: the faceof saidinotch is in} clined or beveled as designated by 13.

Glass sign letters are usually applied to a panel or base by means of screws such as 14 I and when these screws are used in connection with the letter having the notched lugs 11, said screws are positioned in thenotches 12 and as they are driven downwardly into the base or panel, the lower edges of the heads of the screws will bear against the inclined or beveled surfaces 13 of the notches and as a result of this engagement, as said screws thereby eliminating the pressure and stresses that would otherwise tend to fracture and break the lugs or the portions of the bodies of the letters with which the screws engage. As a result of the use of my improved fastening means, the breakage of glass sign letters and the like is minimized, thus producing a decided economic advantage.

Wh1le I have shown and described the screw-receiving notches as being formed in lugs that project from the edges of the bodies of the sign letters, it will be understood that these arcuate bevel-faced notches may be formed directly in the edges of the letters or characters with the same advantageous results.

Thus it will be seen that I have provided simple and eificient means for sign letter of glass, porcelain and the like, and which fastening means may be employedswithout dethe circular base portions of push buttons,

electric bells, and the like, or in fact any glass or porcelain member that is attached by means of screws to a base of wood or the like.

It will be understood that minor changes in the size, form and construction of the various parts of my iinprovcd glass sign letter fastening may be made and substituted for those herein shown and described without departing from the spirit of my invention, the scope of which is set forth in the appended claims.

I claim as my invention:

1. As a new article of manufacture, a sign letter composed of vitrified material, an in tegral lug projecting outwardly from the edge of the body of the sign 1e ter, which lug is provided in its edge with an arcuate screw receiving notch, the entire face of which is beveled whereby the head of 9.

screw that is seated in said notch will be forced away from the lug as a result of contact with said beveled face.

2. As a new article of manufacture, a sign letter formed of vitrified material, a lip projecting from the edge of the body of said letter, the edge of said lip being provided with an arcuate screw receiving notch and the entire inner face of which notch is Leveled whereby the head of a screw that is seated in said notch will be forced away from the lug as a result of contact with said beveled face.

In testimony whereof I afiix my signature.

ALBERT HAMILTON FoRGER.
