SPEGIFIGA'IIQN forming part of Letters Patent No. 744,852, dated November 24, 1903.
Application filed July 24,1901. Serial No. 69,564. (No model.)
To all whom it may concern:
Be it known that I, NOAH S. AMsTUTZ, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Engraving, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to the art of engraving, and is especially applicable to those methods of practicing this art wherein a yielding material is engraved by a pointed tool while said material is held against a relief representation of the subject.
The object of the invention is to facilitate the operation of the tool, whereby greater accuracy and a more faithful record of the subject may be obtained; and the invention consists in certain operations which contribute to these effects, all of which will be more fully described hereinafter, and particularly set forth in the claims.
In the drawings I illustrate a suitable adaptation ofdevice for the purposes named above.
Figure 1 represents, on an enlarged scale, a section through a subject during the engraving operation, the section being taken in the plane in which the tool is cutting. Fig. 2 represents a similar section taken at right angles to the first.
Referring to the parts by letters, A repre sents a regular surface, which may be plane or cylindrical and upon which may be secured in any suitable manner a relief representation of the subject. This should be what is usually known as a carbon-print. As is well known, undulations of the surface of such a print are incidental to variations in light and shade on the same, and I have indicated the outline of these undulations at any point by the wavy line b.
Upon the print B rests a yielding sheet D of recording material, and a cutting-tool C is placed adjacent thereto. This cutting-tool C is made to pass progressively over the entire area of the print B, while it is maintained at a constant distance from the surface A, and its point cuts into the sheet D at any moment to a depth depending upon the elevation of the surface of the print B just beneath the said point. These cuts of varying depth are indicated at d d.
While the cutting operation is taking place i a I press the yielding material D at a point adjacent to the point of the tool 0 by means of a small presser-foot E. This presser-foot is preferably formed with a conic'ally-poi'nted cap e, which may be of sapphire, and a spring 6 operates to press this cap against the recording material. In this manner the sheet D is constrained to conform closely to the configuration of the subject in the vicinity of the cutting-point, and an accurate reproduction or acrotom of the subject is produced.
It is of course immaterial what form of cutting-tool is used in connection with the presserfoot. A rotary cutter could be used, and indeed the use of any form of cutter whatever would be within the scope of this invention.
What I claim is- 1. The method which consists in disposing a flexible material in undulations corresponding to a relief representation of the subject, passing a tool across the surface of said flexible material, and pressing said flexible material adjacent to said tool, substantially as set forth. I
2. The method which consists in engraving a recording material While superposed upon a relief representation of the subject, and simultaneously pressing said recording material adjacent to the engraving-tool, substantially as set forth.
3. The method which consists in superposing a recording material upon a relief representation of the subject, giving said recording material and a tool a relative progressive movement, and simultaneously pressing said recording material adjacent to said tool, substantially as set forth.
4:. The method of engraving which consists in engraving a yielding material while superposed upon a relief representation of the subject, and simultaneously pressing said yielding material with a sapphire point near the engraving-point, substantially as set forth.
In testimony whereof I affiX my signature in presence of two witnesses.
