The object of my invention is to devise the process ofbeing rolledover the plate in a method of producing selected designs on. the direction'shown by the arrow and picking enamel ware, particularly such as used on up the mixture of powdered enamel and oil gas ranges and table tops, etc. from the etched design portion of the plate Among the more specific objects of my into the roller. 55

vention are to produce enamel ware .having Fig. 9 shows an enameled panel, the lower` any desired design and made in'imitation of cross section portion representing the sheet" any material, Such as Wood 0r marble, and metl. pOItlOIl and the Smaller CIOSS SeCilOl'l which permits of great latitude of detail in POIIOII at the top, the enamel. In this figure lo finishing the finer'portionsl of the design, and the roller shown in Fig. 8 is being rolled over '60 which'permits the production of an embossed the enameled surface of the plate in the direcdesign and shading in color and design by tion shownb the arrow, thereby removing the production of high and low lights, and the COatlIlg 0 pOWdered enamel and oil from which permits the production of very fine the IOller and placing it on the enameled line graining eects.

'process has been completed, the hydrofiuoric acid is removed. and the frame barrier is removed, as well as the paint that was applied to the plate in the initial process. The plate is then 'thoroughly washed and cleaned. This .plate may be used repeatedly in the subsequent process. This plate represents the key or match plate of the process. In other Words, the artistry required to make the design is not subsequently necessary. y The next step in ythe process 1s to apply a mixture of powdered enamel and oil to the etched surface of the plate. This is done by placing a heap of the mixture of powdered enamel and oil at one edge of the plate. This heap is designated by the numeral 11 in Fig. 7. Numeral 12 Vdesignates a scraper having the sharp edge 13 and of the same or slightly greater width than the width of the plate 14.

.The scraper 12 is scraped in the direction of the arrow shown in Fig. 7 across the length of the plate 14, with the heap -11 immediately behind it. By this means the mixture of powdered enamel and' oil fills the etched depressions of the plate 14, but does not cover the unetched portions of the plate 14, because lin the process of scraping the scraper 12 removes the mixture of powdered enamel and oil from the high spots or areas, but permits necessary the depressions to be filled up.

The next step involves the use of the rubber roller 15 having the axle 16. The rubber roller 15 is made of solid spongy rubber, which is very resilient. The rubber roller 15 is at least as wide as the plate 14, but preferably not agreat deal wider. The axle 16 vextends beyond the rubber roller 15 on both sides.

The next step involves transferring the design from the plate `14 to the rubber-'roller 15, that is it involves transferring the mixture of powdered enamel and oil from the etched depressions of the plate 14 to the surface of the rubber roller 15. The circumference of the roller 15 must be at least as long as the plate 14 and preferably not a great deal longer. The roller is placed as shown in Fig. 8 at 'one end of the plate 14. Pressure is then applied on the axle 16 and the rubber roller 15 rolled to the left in the direction of the arrow in Fig. 8, until one complete revolution of the roller has been made. In this step in the process, it is highly that the rollery be not permitted to slide. In Fig. 8 the roller 15 is shown in `about its intermediate position between the ends of the plate 14. The mixture of powdered enamel 'and oil adheresto the rubber roller, andJ on account of the pressure on the rubber roller all of the mixture is removed from the etched depressions in the plate 14. That is to say the design has been transferred from the plate 14 to the lateral surface of the rubber roller 15. It is to be noted that the greater the etched depressions the higher the elevations of the design will be on the rubber roller 15. Y

The process resembles that of wrapping the design around the rubber roller 15.

The next step is to transfer the design from the rubber roller 15 to the' plate 17. The plate 17 is enameled as shown at` 18 in its completed form before the design is transferred from the roller 15. The roller is placed at one end of the plate 17 as it was on the plate 14 and rolled in thedirection indicated by the arrow in Fig. 9, under pressure applied to the axle 16 until the entire design is pasted or stuck on the plate 17. It is likewise necessary in this operation that the roller be not permitted to slip. This operation resembles an unwinding of the design from the roller 15 and laying it flatly on the plate 17. The plate 17 is then placed in an oven and the design baked on just as all enamel is baked` on metal. When removed, from the enameling oven and permitted to dry, the plate 17 will assume the appearance shown in Fig. 10. Within the limitations necessarily existing in an inked drawing, Fig. 1() shows the delicacy of design, which is permitted. If the' stance of which theblank plate is made, y

scraping or cutting a desired design in the substances on the plate and etching the design in the plate by the application of acid, filling the depressions of the design on said plate with a viscous material, applying the viscous material filling theV depressions of the etched design to a resilient roller by passing the roller over said plate and transferring the viscous material forming a design from said roller to a given plate by rolling said roller lover said given plate and then baking said given plate.

2. In a method of the character described, making a. master plate, which consists in coating a sheet of glass or metal with asphalt paint, carving a design in said paint, after it has dried,'building a confining wall around @said plate, and covering said plate with hydrofluoric acid, until the exposed portions y of said plate are etched, removing the acid confining means as well as the acid, and washing the plate, then filling the etched depres- 5 sions on said plate with a', mixture of'powdered enamel and oil by scraping a heap of the same across said plate, thereby permitting it to fill the depressions and removing it from the elevations, then transferring the mixture 10 in the design form from said plate to a resilient rubber roller by applying. pressure to the roller and'rolling it from one end of said plate to the other over the etched depressions, then transferring the design from the roller to a given plate by rolling said roller from one end of said given plate to the other under v pressure, and then baking the given plate.

In testimoni whereof I ailix. my signature. A PHONSE E. FELLNER.
