Human STATES JOSEF RIEDER'I or neuron, GERMANY.-
PROCESS OF AND APPARATUS-FOR PRODUCINGRELIEFS m METAL.
SPEGIFICATTON forming part of Letters Patent No. 607,484, datedJuly 19, 1898.
Application filed December 21, 1897. Serial No. 652,842. (No model.) Patented inGermany February 7 1897, No. 95,081; in
I France June 30,1897, No. 268,332, and in England Jun6'30, 1897, No. 15,617:
To all whom it may concern:
Be it known that I, J OSEF RIEDER, a subject of the King of Bavaria, and a resident of Munich, Kingdom of Bavaria, Germany, have invented new and useful Improvements in Processes of and Apparatus for Producing liefs in metal by means of electrolysis.
The process consists in first-taking an impression of the relief on one side of a porous block of, say, plast'er-of-paris, English cement,'terra-cotta, natural stone, or the like."
The impression may be attained /by casting in the case of plaster-of-paris,,,by pressure and subsequent firing in the case of terracotta and the like, or by engraving in the case of natural porous stone, and "in order to render the present specification more easily 1 intelligible reference is bad to the accompanying drawings, in which similar letters of reference denote similar parts throughout the several views. w l
Figure 1 is a diagram of one form of carrying the invention into practice; Fig. 2, a
,. similarrepresentation of a modified form} I modification.
Fig. 3, a similar representation of a further In the drawings, E represents the block or .mold, of plaster-of-paris or the like, on which a plate of suitable metal; (designated by the letter K) is laid, said plate being in connection with the negative pole of a suitable source of electricity. On the embossed or relief side of the block E is placed the metal plate which is to receive the embossment or relief, said plate being designated by1 the letter A and in connection with the positive pole of a battery. If now the block E is saturated with an electrolyte which will dissolve the metal of the plate A, an electrolytic apparatus will be formed, in which E represents the receptacle with the electrolyte, A the anode, and
will be dissolved from the plate A in the wellknown manner at all points of the same which come into contact with the porous block E.- By constantly adding fresh electrolyte to the block finally all parts of the metal plate A will come into contact with the same, and] as soon as this has taken place the plate will'be' finished.
This process will not suffice for making big reliefs, in which case it is necessary-to press the plate K against thefblock E by meansof a spring devicef.
The process may beemployed" for making steel stamps for coins, for copying coins and medals, for providing metal parts or mountings with relief-like ornamentations, for making clichs for print-in g purposes, and for boring holes in hard steel and many other similar purposes.
"In carrying the above-described process into practice the electrolyte must be carefully chosen, the current must be properly regulated, and various auxiliary devices will have to be employed which do not, however, make any difference in the main system of the process.
serving mainly for copying coins, the three main parts of the devicethe plates A and K and the block E--didering only in embodiment from those described with reference to the diagrams. The block E is mounted in a protecting-sleeve 'e andthe connection between block E and the cathode K is formed by c is supported in the cover d, which also carries a form or guide plateh, in which the anode -"-A fits, so that the same, if removed, may be position. The anode A is pressed against the mold-block E by means of a bow-spring b, secured to cover (1 atn, .so that as the plate A is .dissolved'it willi gradually sink into the mold. In order to get a good clean reproduction, it is necessary to remove the plate A at remove the dissolved metal from the same.
K the cathode. If the current is passed The plate A may be cleaned by means of "a Thus one form of carrying the invention. into practice is shown at Fig. ,3, this device the electrolyte in the receptacle g. The sleeve replaced in the mold in exactly the same suitable intervals-and brush off or otherwise through the apparatus thus formed,'metal a rotary brush of any known construction, and any suitable devicemay be employed to remove and replace the same automatically.
I claim as my invention- 1. A process for'reproducin g reliefs and the like in metal by means of electrolysis, which consists in first producing on a porous mass a negative of the original to be copied, pressing a plate connected with the cathode of an electrolytic cell to one side of said block, placing the plate on which the relief is to be reproduced at the negative side of said block and constituting the same the anode, supplying the electrolyte to the porous block and supplying an electric current substantially as described.
2. A process for reproducing reliefs and the like in metal by means of electrolysis,which consists of first producing on a porous mass a negative of the original. to be copied, pressing a plate connected with the cathode of an electrolytic cell against the plain side of said i block, placing the plate on which the -relief is to be reproduced at the negative side of said block and constituting the same the an ode,gently pressing said plate on said block,
manner and for the purpose substantially as described. I ,l
3. A device for carrying out the process of reproducing reliefs by means of electrolysis,
4. An electrolytic apparatus composed of a cathode, aporous mold-block, an anode in contact therewith, and an electrolyte that saturates the mold-block, substantially as specified In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
