In the electrodeposition of gold upon silver or other suitable cathode material, the quality of relative brightness or lustrousness of the two faces of the gold film is dependent upon a number of factors, suchas the degree of refinement" of the bath, the degree of refinement of thesilveror other cathode material, the relative amount in theelectrodepositing solution. of metal other; than gold, the temperature of the bath.

drawing, in which V Fig. 1 is a perspective view typifying one em bodiment of a paper mounted gold film, pursuant to my-invention. Fig. 2 is a transversesection of the pape jll fication of feeding the carrier strip relative to the released film.

The roll illustrated in Fig. 1 comprises a carrier ill of paper having its opposite faces Illa, lllb, see also Fig. 2, of suitable nature or suitably treated, the film ll of gold being supported by theface Illa.

For example, the face Illa of the paper strip may be uncalendered or otherwise relatively rough, as compared with its opposite face lllb, which may be calendered. Or the relatively roughened face Illa may be formed by spraying or otherwise depositing oil or other suitable procedure.

The face lllb of the paper strip may be rendered smooth by applying rouge, French chalk or the like.

Such or equivalent manufacture or treatment of the paper strip having the gold film supported on its face Illa may be rolled as is indicated in Fig. 1, without being subject to spoilage of the gold film adhering. to such face Illa. Upon unrolling the paper strip ID, the gold film II is simultaneously and to corresponding extent unrolled and properly supported by the paper carrier.

In the circumstance that the gold film is had by eleotrodepositing, one face of the deposited film is brighter or more lustrous than the opposite face. I prefer to mount the gold film upon the paper or other carrier to present its less bright or less lustrous face; by such mounting, the brighter or more lustrous face of the gold becomes the exposed face of the gold when applied in sign painting, and other decorative arts, by the procedure of first treating the glass, china, etc. with sizing ahd applying the gold film to the sized surface, the paper or'other carrier being employed in the transfer asa support and means of conveyance.

If desired, the strip ID of paper or equivalent and the supported co-extensive film of gold or equivalent may be severed into lengths, and bound into a book, as is indicated in Fig. 5.

Preferably such book l2, see Fig. 5, is constructed as is disclosed in my aforesaid co-pending application Ser. #725,583, filed May 14th,

If preferred, the gold film Il may be mounted on the paper strip NJ to present the brighter or more lustrous face of the gold.

One suitable procedure of deriving a paper or equivalent supported film of indefinite coextensive length is indicated in Figs. 3 and 4, the applied arrows showing the paths of travel.

The coiled roll 16, see Fig. 3, represents a coiled composite strip of, say, gold adhered to silver, such as is derived by the stated electrodeposition method. Such roll "5 is unwound to present the gold upwards and the silver downwards; thus ll represents the gold or upper face of the Com-.-

posite strip fed into the indicated bath ll, of suitable silver-removing agent, such as dilute nitric acid. l8 represents the silver or lower face of the composite strip.

The succeeding bath I9 is desirably water, serving to remove any residue of nitric acid from the released gold film II. It is highly efficient to employ a succeeding step for the removal of water from the released gold film ll, viz. by treatment with alcohol, as in a bath 20 of alcohol.

A preferred detail process of releasing the gold film I l and mounting the same upon a paper carrier I0 comprises positively feeding the composite gold-silver strip Hl8 at a substantially constant rate in the respective baths l1, I9, 20, including the transits 2l,'22, from bath I! to bath l9, .and from .bath I9 to bath 20, and further including the feeding of the paper ID from its indicated roll or equivalent to and with the released gold film at the terminus of the bath .20, as is indicated in Figs. 3 and 4.

Also, as is set forth in the aforesaid Demel Patents No. 1,512,825 and No. 1,513,696, it is advantageous to.fioat" the composite film lI-l8 on the surface of the nitric acid bath l1, and similarly to float" the released gold film on the surface of the water bath l9 and the alcohol bath 20.

Preferably, the respective baths arecontinuously replenished by feeding in the respective solutions at regulated strength and/or purity as by inflow pipes Ila, 89a and 20a or equivalent. l'lb indicates an outflow pipe, for withdrawal of the bath H, the pipe llb being advantageously disposed in vertical position to thus regulate and maintain the level of the bath l'l. Similarly, for the'respective baths l9 and 20, I912 represents the outflow pipe for the water bath l8, and 20b for the alcohol bath 20.

The transfer 2| may comprisean endless belt, as indicated, passing over the ldlers 2la, the belt being positively driven by the pulleys 2"), the shafts of which extend through suitable gaskets in one side of the tanks, to which shaft gears 2 le are secured. Similar parts are correspondingly designated for the transfer 22.

The said gears 22b and 2 lb are positively driven by any suitable driving means, such as a. driving shaft 23, suitably mounted in bearings 24. The intergearing of theshaft 28 with the gears 22?), Zlb may be had by worms 25, in which instance the gears 22b, 2 lb are skew gears, or worm wheels.

The positive feeding of the composite goldsilver strip ll-|8, may be effected by the worm 28, see Fig. 3, which meshes with the skew gear or worm wheel 21, in turn meshing with the worm 28 and the skew gear or worm wheel 29, to the shaft of which is secured the roll 30. The roll 30a cooperates with the roll 30' to positively feed the composite strip l|-l8 at a uniform rate to the level of the bath ll of nitric acid. a

The positive, feed of the paper I0 is had by at the regulated uniform speed to the concurrently transited water-freed film II at the terminus of the alcohol bath 2B,.and the thus paper mounted gold film is positively withdrawn, as by.

reeling the same as a roll, as indicated in Fig. 3. The roll 3Ia may be heated, as by means of an embodied electrical resistance for the purpose of expediting the removal of alcohol and/or other liquid from the gold film and/or paper strip.

The-manner of positioning of the gold or other metallic film relative to the supporting paper is carried out in any suitable manner. Pursuant to the embodiment of this phase of my invention as illustrated in Fig. 3, the positioning of the film in contact with the relatively rough face or the relatively smooth face of the carrier is controlled by the manner of feeding the carrier strip to the released film. Thus, referring to Fig. 3, and assuming that the face of the gold film immediately adjacent the cathode material to be brighter or more lustrous than the opposite face of the deposited film, the carrier I0 is fed from the feedout roll IDA shown in Fig. 3 with the smooth face lb of the carrier facing downwardly, whereby upon reeling the carrier and supporting film to form the roll IOB, see Fig. 3, the greater adherence of the gold film to the roughened face of the carrier effects the desired relative position of the film with respect to the carrier, namely to locate the bright or more lustrous face of the gold film in adherence with the relatively roughened face of the carrier.

To attain the reversed face relationship of the film and the carrier by the procedure illustrated in Fig. 3, the feed-out roll IDA of the carrier is fed with its roughened face downward, at substantially the speed of the released film, thus obtaining a reeled roll IIJB presenting the dull or less lustrous face of the film upwards, by reason of the greater adherence of the relatively roughened face of the paper strip to the thus positioned brighter or bright face of the film. In

the circumstance that the dull or less lustrous ing the carrier to the released metallic film at the terminus of the bath 2!], or equivalent, the roll IDA representing the feed-out roll of paper and the roll NIB, similarly as above, the reeled roll of. gold film supported by the carrier I0. In the procedure illustrated in Fig. 6, the carrier I0 is passed through the bath 2!] lowerly about and in contact with the roll 3|, and is thus brought under and at substantially the speed of the released film floating on the level of'the bath 20, whereby the released film is supported by the carrier ,ID in the desired relationship. Assuming, again, that the brighter or more lustrous face of the film is the face adjacent the cathode material, to positicy s'uch brighter or more lustrous face of t e gold film adjacent the relatively roughe ed face of the carrier, the strip I0 is fed from t e feed-out roll IOA-to position its rougherred face lowerly, whereby upon its transit about the roll 3|, such lower face, in this instance its roughened face, is brought in contact with the bright or more lustrous face of the gold film, to which face of the carrier the film maintains adherence when rolled into the roll 10B, and similarly subsequently when unwound from such roll, as indicated in Fig. 1.

In the instances above disclosed, wherein the carrier material is submerged under a fluid, such "as water, alcohol, etc.,,.or passed through fluid, or otherwise subjected to the action of a fiuid, the material is selected of such character to be unaffected by the fluid, inclusive of absence of expansion or contraction due to the fluid, as will be understood by those skilled in the art.

Similar procedure is carried out in the use of a carrier having one face treated with oil or other adherence imparting medium.

Similar procedure is had in the use of a carrier having one face treated with rouge or other smoothness imparting medium.

It will be observed that the positioning of gold or other metallic fllm having one face relatively bright and its other face relatively dull, with respect to its supporting carrier, affords identification of the relatively bright face of the film, an advantage of marked importance in the trade use of the film as in sign painting and other decorative arts, in roll or book form, or in stamping, etc.

It is noted that the length of gold or other metallic film derived by electrodeposition is indefinite, whereas the maximum length of beaten gold produced by gold beaters does not exceed seven inches.

It appears, as above set forth, that my process affords the production of gold film mounted freely upon a suitable carrier, the length of the film appreciably exceeding that of beaten gold, the film preferably having a uniform thickness throughout its length.

Whereas I have described my invention by reference to specific forms thereof, it will be understood that many changes and modifications may be made without departing from the sp rit of the invention.
