UNITED STATES ELROY A. CHASE, OF NORTHIEIELD, VERMONT.
METHOD OF ORNAMENTING STONE.
Application filed October 1, 1924. Serial No. 741,062.
This invention relates td a method of or-- namenting stone by which improved results may be attained at greatly reduced cost.
Such work has commonly been produced by cutting or engraving the stoneby use of a sand blast directed against the. stone through some form of pattern or stencil.
The usual procedure has been to apply a coating of a glue-like substance to the surface of the stone and to form the stencil by cutting away portionsof this glue-like -coat ing. This method is effective and produces satisfactory results but is very expensive, as the stencil can be used once only and is then necessarily destroyed-in removal from the stone. It is the object of my invention to provide an improved method or process of ornamenting stone which will permit metal or other permanent stencils to be employed, while at the same time producing a high quality of work. f
To the attainment of this object, animportant feature of my invention relates to the provision of a relatively soft packing material between the stencil and the work, which material is readily cut out by the sand blast beneath the openings in the stencil, but which prevents the entrance of sand under the edges of the stencil. Sharply defined workis thus produced.
Further details of my invention are hereinafter described and more specifically'set forth in the appended claims. I
A preferred form of my invention is shown in the drawings, in which Fig. l is a perspective view of a portion of a block of stone having a stencil and packing material applied thereto, according'to my improved method;
Fig.2 is a detail sectional elevation taken along the line 2-2 in Fig. 1;
Fig. 3 is a view similar to Fig. 2, but showingthe parts after the sand blast has been applied; and
Fig. 4 illustrates another use of my invention.
Referring to the drawings, I have indicated a block of granite or other stone 10 upon which letters or other ornamental markings'are to be cut or engraved. The
block of stone 10 is first provided with 'an' approximately smoother finished surface 11 soft packing material 12.
.tached' portions in the stencil may be asupon which 1s placed a sheet of relatively Different sub stances may be used for this purpose, but I have found that a rather thick sheet ofordinary blotting paper is satisfactory.
The stencil 13 is next secured in position A I over the packing 12 and may be held from movement thereon by clamps, not shown, or
in any other convenlent manner. The stencil 12 may be formed of any suitable material, such as cast iron or other metal, or it may be formed of vulcanized fiber.
With the parts thus assembled, a sand blast is directed against the outer face of the stencil and quickly cuts away the packing material 12 behind the' stencil openings 14 in the stencil 13. The surface of the stone is thus directly exposed to the sand blast, which will then sink the design in the stone, as indicated at 15 in Fig. 3. The packing material 12 forms a tight joint around the openings in the stencil and prevents the sand blast from cutting away the edges of the stone under the stencil around the openings therein. The sharp edges of a design are thus preserved and an ornamentalresult of high quality is achieved. The use of the packing material also avoids the necessity of reat accuracy in surfacing the stencil an the stone, as the relatively soft packing will adapt itself to slight inequalities while preserving a tight joint.
In Fig. 4, I have illustrated the adaptation-0f my new process to the invention disclosed in the prior patent to Sanborn and Haslan, No. 1,500,272. In' the method described in said atent, a screen is placed in front of a stenci or design, so that the background is broken up by ribs or ridges, thus producing a more pleasing and ornamental effect. Similar results can be obtained in connection with my invention, by placing a screen 20 in front of the stencil and packmg assembled as above described. If the pattern calls for detached figures entirely surrounded by a depressed background,.the desembled on the back of the screen, which thus holds the different parts of the stencil in their correct relations. When used with the screen, the packing between the stencil and the stone serves the purpose previously described, but the depressed background is broken up by ribs or ridges, as shown by the patent cited.
Having thus described t he advantages thereof, I do not my invention and wish to be 119 wise than as set forth in the claims, but
. What I claim is 1. The method of ornamenting stone which consists in mounting a stencil on a block of stone with a relatively 'soft packing material interposed between the stone and the stencil, cutting away the packing material behind the stencil openings by the action of a sand blast, and thereafter depressing the design in the stone by directing the sand blast through the openings in the stencil and packin material.
2. Tile method of ornamenting stone which consists in providing a relatively smooth surface on a block of stone, placinga sheet of relatively soft packing material on said stone, mounting a stencil on said packing material, and directing a sand blast against said stencil, thereby cutting away the packing behind the stencil openings and depressing the stone surface thus exposed.
3. The method of ornamenting stone which consists in providing a relatively smooth surface on' a block of stone, placing a sheet of blotting paper on saidsurface, mounting a stencil on said blotting paper and stone, pressing the same firmly against the paper and stone, and directing a sand blast against said stencil, whereby the paper behind the stencil openings is cut away with the remaining portions of the paper preventing entrance of sand under the edges of the stencil openings.
4. The method of ornamenting stone which consists in providing a relatively smooth surface on a block of stone, placing a sheet of relatively soft packing material on said stone, mounting a stencil on said packing material, placing a screen in front of said stencil, securing said screen and stencil in position, and directing a sand blast against said screen and stencil, thereby cutting away the packing behind the stencil openings and depressing the stone surface thus exposed and at the same time forming ridges or ribs on the background thus produced.
5. The method of ornamenting stone'which consists in providing a relatively siiiooth surface on a block of stone, placing a sheet of relatively soft packing material on said stone, securing a stencil to the back of a screen, mounting said stencil and screen in fixed position on said packing material, and directing a sand blast against said screen and stencil, thereby cutting away the packing behind the stencil openings and depressing the stone surface thus exposed and at the same time forming ridges or ribs on the.
background thus produced. In testimony whereof I have hereunto affixed my signature.
