SPECIFICATION formingpart of Letters Patent No. 747,639, dated December 22, 903- Application filed April 9; 1903- Serial No. 151,869. (No model.)

To all whom it may concern.-

Be it known that I, CARL RASCHIG, a resident of the city of Berlin, Kingdom of Prussia, in the Empire of Germany,have invented new and useful Improvements in Gilding-Machines, of which the following is a specification.

The impressing or stamping of gold and otherwise colored edges on bars of wood for picture-frames and the like has hitherto been done by hand, thesheet-gold or other sheet metal being first applied to the parts of the bars which were to bear the colored impression or ornamentation, after which the bars were fixed on the workbench and the workmen went over the'previously-applied strip of sheet metal or metal leaf with an impressing-roller fixed on a long handle,exerting considerable pressure on theimpressing-roller. This method occupies a great deal of time and requires considerable personal exertion. I therefore propose to operate the impressing by mechanical means, the bars being passed beneath a revolubly-mounted and weighted impressing-roller. The bars are cont-in uously passed through by mechanical means and at the same time the sheet metal or metal leaf in the form of a very thin metal roll is automatically fed to the impressing-roller, care being taken to constan tlyheat the impressing-roller.

The machine for carrying out this improved method is shown in the accompanying drawings, Figure 1 being a side view, and Fig. 2

Fig. 3 is a section on lines 3 3 of Fig. 1.

A shaft 3 is mounted on a table 1 by means of bearings 2, on which shaft an H-shaped arm 4 is pivotally mounted. The arm 4carries a hollow shaft 5 at its front end. On the latter clamp-bushes 6, clutches, or the like are provided, which hold .the impressing-roller firmly on the shaft 5. These parts are of course arranged in such a way as to allow of the impressing-rollers being easily changed. A chain-wheel 9 is mounted on the'shaft 3 between the upper bearing 2 and the fast and loose pulleys 8, which wheel 9 transmits the operating motion, by means of achain 10, to a second chain-wheel 11. This second chainwheel is mounted on a shaft 12, running parallel to the shaft 5, but beneath the table. A roller 13, Fig. 1, is mounted on the shaft 12, exactly vertically beneath the impressingroller.

A support 14 is fixed on the arm 4 and carries at the top a roller-holder 15. A guidegroove 16, oflight spring sheet metal,bent into a substantially as described U section, leads downward to the place where the impressing takes place.

If, for instance, a roll of so-called rolled gold or gold-leaf l9-that is to say, sheetgold applied on strips of paperbe inserted in the roller-holder 15 and the end of it drawn down, themachine is then ready for work. In the case of the first bar to be inserted a piece of the drawn-off rollgold is held by hand flat on the table, the bar is pressed thereon andpushed forward until it comes under the impressing-roller. The roller 13 then grips the bar and draws it through. When one bar has been stamped or impressed, a second is introduced, and care must be taken that the ends of the succeeding bars press closely one against'the other (see 17 and 18, Fig. 1) by pushing the succeeding bar by hand for a moment. The inherent weight of the arm 4 is sufficient for weighting the impressingroller in order to obtain a suflicient pressure to produce the impression in the case of small narrow impressions or ornamentations; but for larger patterns weights must be placed on the arm 4.

The impressing-roller is heated by means of asmall Bunsen burner 20, which is fixed to the table by means of any suitable holder in such a way that its mouth projects into the hollow shaft 5. Guide bars and springs, as shown in Fig. 2, may be provided on the table for guiding the frame-bars.

Having now particularlydescribed and ascertained the nature of my said invention and I in what manner the same is to be performed, I declare that What I claim'is In a machine of the class described the combination of an impressing-roller 7, an arm 4 pivotally supported and carrying said roller, a supporting and conveying roller 13 arranged below the impressing-roller, a roll-holder 15 carried by the pivoted arm 4 and a guide 16 extending from the roll-holder to the impressing-roller, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

CARL RASOHIG.
