EIVIBOSSING-ROLLER.
SPECIFICATION forming part of Letters Patent N70. 615,703, dated December 13, 1898.
d Application filed July 6, 1896. Serial No. 598,179. (No model.)
.To all w/wm t may concern:
Be it known that I, J ULIUs Horlunrnaa subject of the Emperor of Austria-l-Iungary, residing at Vienna, in the Empire of Austrial-Iungary, have invented new and usefulIln- `provements in Embossing-Rollers, of which the following is a specification.
The invention has been patented in England, No. 16,222, dated August 25, 1894; in Germany, No. 82,530, dated August 2G, 1894; in France, No. 240,984, dated August 25, 1894; in Belgium, No. 111,550, dated August 25, 1894; in Russia, No. 425, dated November 28, 1897, and in Austria-I'Iungary, ilo. 6,514/ 5,722, Registerband 44.
My invention is an improved embossingroller; and it consists of the features hereinafter described, and particularly pointed out in the claims.
Figure 1 is a cross-section of the plate containing the design. Fig. 2 is a side View of the same. Fig. 3 shows the plate bent ready to be placed onl the roller. Fig. 4 is a crosssection g Fig. 5,a perspective view of the roller on which the plates are placed. Fig. G'shows a cross-section of the roller with the plate placed on it. Fig. 7 is a view of the plate fastened on the roller with parts in section. Fig. 8 is a side view of the rolling-mill in which the roller is used.
The leather the grain of which is to be reproduced is covered on its grain side with a coating which is a good conductor of electricity, and a thin layer of metal is then precipitated thereupon inv the galvanie way in the electrolytical bath. Care is to be Vtaken that the coating be not thicker than two or three millimeters, as otherwise when afterward the plate is bent the design of the grain reproduced thereupon would be distorted. To the back side of the head end of the metallic plate d prepared in this way, Figs. 1 and 2, close to the border, an iron transverse rail b is riveted or otherwise secured. The plate is then. bent round on a plate-bending machine, Fig. 3, and applied to a rollerc, Figs. 4 and 5, susceptible of being heated inside and provided with a transverse groove d, extending parallelly to the longitudinal axis of the roller. The transverse rail l) is engaged in the groove cl and fastened therein by means of screws, while the whole remaining part of the plate dinal and lateral direction.
Y lies loosely upon the roller, so that it may freely expand under the action of heat, Fig. 6.
The roller is of such diameter that it is not completely inclosed by the plate. There remains, therefore, between the groove d and the free end of the plate a free intermediate space oc, Fig. 6, permitting the plate to expand without covering with its free end the groove d or the rail l). The plate being fastened, as above described, only on one end to the roller, its free end would spring off as often as it had passed the counter-roller. avoid this, rings e are pushed over or fixed to the front sides of this roller, Fig. 7, holding down the said plate to the roller without raising obstacles to its expansion in the longitu- 'lhe roller is then placed in an ordinary roller-press. The counter-roller f of this press has its front ends at g turned off, aording the ringse, pushed upon the roller c, the necessary space.
In Working the paper or the like is passed through between the revolving rollers. The roller a is revolved in such a manner that the place Where the rail b is arranged comes rst against the roller f.
I claim-- 1. An embossing roller yor cylinder having an embossing-plate xed thereto along one extremity leaving the other extremity free and the hollow rings around the edges of the embossing-plate coninin g the same loosely in order to prevent the free extremity of the plate from leaving the cylinder, substantially as described.
2. An embossing roller or cylinder having an embossing-plate fixed thereto along one extremity leaving the other extremity free and the hollow rings around the edges of the embossin g-plate confining the same loosely in order to prevent the free extremity of the plate from leaving the cylinder, said plate being secured to the roller by a bar on one edge of the plate fitting in a groove in the roller, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
JULIUS HOFMEIER.
