GLASS-CUTTING ROCE S FOR TRANSLUGENT ARTICLES.
To all whom it may concern:
Be it known that I, HARRY V. DYoH, a citizen of the United States, residing at Philadelphia, 11 the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Glass-Cuttin-g Processes for Translucent Articles,
which the following is a specification.
My invention relates .to new and useful improvements for 'translucent articles, and more particularly to the matting-designs on electric light bulbs or lamps which are translucent because of a surface generally known as frosted.
In order to cut ontranslucent electric designs, figures or the like lamps or other that such-articles be prepared or treated so that a portion thereof will apparently become transparent through which portion a distant wall will be readily visible in order for the operator to see the cuts as they are made on a distant translucent wall. In the optical art it is a well known fact that a broken surface such as represented by the frosted glass will reflect some light rays and refract others and this surface may be temporarily restored by covering the same with a liquid which fills the crevices and in effect produces a light rays will pass unobstructed, therefore the portion thus treated becomes transparent.
One of the objects of my invention is in making use of this optical law and the circumstances just referred to in cutting designs on translucent bulbous articles and is carried out by applying a liquid to a portion of the frosted surface opposite that on which the design is to be cut, thereby producing a transparent area through which the cuttings on the distant surface will be visible to the operator. It is preferable that the liquid used be an oil, such as common machine oil, linseed oil or the like, as this will not dry so quickly and therefore will maintain the treated area in a'transparent condition until the cutting operations have been completed, whereas if water-is used this tends to evaporate before the work can be completed.
The process consists in applying a liquid to the surface of a translucent bulbous article so that said treated surface will permit the passage of light and therefore, in effect, be transparent, through which a diswise removing the liquid to condition.
in a glass cutting process- Applieation filed December 12, 1924. Serial No. 755,397.
tant wall will be readily visible, then cutting the design or figure on the distant translucent wall in the ordinary manner and then absorbing, evaporating or other- 7 return the treated surface to its ,normally translucent \Vith these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.
In order that those skilled in the art to which this invention appertains, may understand how to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawing.
forming a part of this application, in which I v Fig. 1, is a side elevation of an electric lamp or bulb ofusual construction showing the translucent glass body.
Fig. 2, is a similar view illustrating the appearanceof the electric lamp or bulb after a portion of its surface has been treated or had a liquid applied thereto.
Fig. 8, is anend view of the electric light bulb illustrating that step in the process at the completion of the cutting.
Fig. 4:, likewise is a side elevation of a finished electric light bulb produced by the use of my process.
In carrying out my invention as here embodied, 2 represents an electric lamp or bulb as a whole including the frosted glass body 3 and the threaded metal plug 4:. My process will be described in connection with the treatment of frosted or translucent bulbs, it being understood that the frosting of a plain bulb may be accomplished in the ordinary or well known manner as by acid etching or grinding the surface with a steel brush having carborundum thereon.
The area of the frosted body has a film of liquid such as wateror oil, preferably the latter, applied thereto to produce in effect a wall having opposite substantially parallel faces to permit the unobstructed passage of lightrays therethrough so that a transpai ent area 5 is provided opposite the wall on which the cutting operations are to be carried out and therefore the cuttings may be readily discerned as will be obvious from Fig. 3.
After the cutting operations have been completed. the liquid is removed either by evaporation, absorption or any other desirable way thus returning the frosted surface to its normal translucent condition.
The bulb in the region of the cutting is polished after being cut so as to give it a finished sheen.
From the foregoing description it will be particularly noted with electric lamps or bulbs treated by this process not only makes the article ornamental but permits the passage of some of the light rays without greatly reducing the non-glaring properties of a frosted bulb.
Of course I do not wish to be limited to the exact details of construction as herein shown as these may be varied within the limits of the appended claims without departing from the spirit of my invention.
Having thus fully described my invention, what I claim as new and useful is 1. The process of cutting translucent bulbous articles which comprises the treating of an area of the translurent surface with a liquid to provide, in effect, a transparent portion whereby the opposite wall will be visible, then cutting a design on the surface visible through the transparent portion and then removing the liquid to return the treated surface to its normal translucent condition.
2. A glass cutting process which comprises the application of liquid to a portion of the surface of a frosted bulb in order to provide, in effect, a transparent area, then cutting the outer surface of said bulb opposite the liquid treated portion and then removing said liquid. I
3. The process of cutting bulbous frosted articles which consists in applying a temporary film of oil to an area of the surface opposite that on which the cutting is to be made, then cutting the surface opposite the treated portion and then removing the oil film.
In testimony whereof, I have hereunto affixed my signature.
HARRY WV. DYCH.
