Patented Dec. 4, 1906.
Application filed February 15,1905. Serial No. 245,774.
Be it known that l, GUSTAV Fiscnnii, manufacturer, a subject of the King of Prussia, German Emperor, residing at No. 16 Friedrichstrasse, Berlin, German Empire, have invented new and useful improvements in Metallic Matrix-Plates, of which the following is a specification.
My invention relates to matrices for producing galvanoplastic reproductions or clec- T trotypes of printers forms, wood blocks, and the like.
According to my invention the operation of forming a matrix by pressing or forcing down the type or block upon a soft-metal plate is essentially facilitated by the back of the plate being provided with grooves,whereby the metal'during the pressing operation more readily rises or swells up, so that the lights in the galvanoplastic cameo shell are of such depth that subsequent treatment of the same, such as chiseling or cutting out, is rendered unnecessary.
One form of plate according to my invention is illustrated in the accompanying drawl ings, in which Figure 1 shows a back view ofa corner portion of a plate having longitudinal and transverse grooves. Fig. 2 is a section on the line A-B of Fig.- 1.
The the bac r of it by rolling, stamping, cutting, or otherwise is treated in such a manner that grooves, furrows, or the like are formed,-
which are preferably made so that they decrease in size from the surface of the plate inward.
In the drawings the plate a is illustrated as being provided with longitudinal and transverse V-sha ed grooves b, whereby a large as semblage o pyramidal elevations (in the fig ures shown s truncated pyramids) result. The back of the plate thus resents a checkered surface. Naturally t 1e grooves, furrows, or the like may run in an inclined direction and simple parallel grooves or Eurrowsthat is, without crossing-'may' also be provided.
The depth, size, shape, and number of the depressions, and thus of the projections or plate a, is preferably made of lead, and
! elevations resulting therefrom, may greatly vary, depending upon the nature of the original, whether a wood block, form, or the like. i ll by means of a press an engraved wood block or the like is pressed down onto a plate prepared in the above-described man- 1 nor, a very sharp intaglio impression results without the original being in any way injured, for owing to the. pliability of the recessed plate the pressure necessary is very much less than in the ease of an ordinary sol ti metal cplate. For example, with my new ini dente plate iii'ty atmospheres pressure is i sullicient, where ninety atmospheres would 2 be requisite with an ordinary softanctal l plate.
A special advantage of my new method is that on the application of ressurc the metal very readily rises or swel s up, as it were. Thus the lights in the galvanoplastic cameo l shell or electrotype, which is made by means of the mold or matrix, are of such depth that subsequent cutting or chiseling of these portions is rendered wholly unnecessary. Another advantage of my improved metal matrix-plate is that it presents a regular surface on the back, which is a matter of much convenience in backing or mountin the electrotype shell. Not only is the worlr facilitated, but the character of the matrix finally obtained is very superior.
Having thus described my invention l claim as new 1. A metallic matrix-plate for producing galvanoplastic reproductions, the back of which is provided with parallel grooves.
2. A metallic matrix-plate for producing galvanoplastic reproductions, provided on its ack with crossing grooves.
3. A metallic. matrix-plate for producing galvanoplastic reproductions, PIOVldBd on its back with longitudinal and transverse V- shaped grooves, substantially as set forth.
