METHOD FOR MANUFACTURING IMITA'IION GOLD-LEAF.

To (ill who/nit 'H'Mlj/ concern:

scribed with reference to the Be it known that I, ARTHUR G. ZI'MMER, a citizenof the United States of An'ierica, and a resident of East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Methods for Manufacturing Imitation Gold-Leaf, of which the following is a specification.

The present invention relates to improvements in methods and apparatus for manufacturing imitation gold leaf, and has for its object to provide such means whereby a superior quality of imitation gold leaf may be produced, resembling more closely real gold leaf and possessing strength, durability, luster and other advantageous qualities which will render it commercially desirable. rinother object is to provide such means by which the thickness-of the leaf may be regulated desired and by which the leaf will have a uniform thickness throughout.

With these and other objects in view, invention is hereinafter more fully deaccompanying drawings and will be finally pointed out in the claims.

in the accompanying drawings,

Fig. 11 is a cross-sectional view'thereof. Similar reference characters indicate cor responding parts throughout the several figures of the drawings.

Referring to the drawings and more particularly to Fig. 1 thereof, the liquidlO or other suitable material from which the imitation goldleaf is formed as a mixture of collodion, alcohol, ether and bronze in suitable proportions, is placed upon the bed or late 11, which has a very smooth and ighly polished surface, which. mayheprd deced in any convenient manner, such for Speciiipation of Letters Extent.

This space, as to above pointed out, corresponds to the thickness of the sheet to be produced, and in drawing the roller over the plate the liquid is spread into a smooth unbroken sheet of a 1 corresponding thickness. drawn over the plate simply once, or if'desired, maybe drawn back and forth several times, after which it is removed and the moisture is allowed to evaporate'from the material, whereupon the sheet ma plate.

In Fig. 6, the plate is disposed within a 24% support the same in spaced relation with the squeegee, which is provided. at the ends engage the sides of the bed and provide guide for thesame. By adjustment of the screw, the plate may he raised or lowered as desired.

lln the form shown in Fig. '3', the plate is us with recesses 25, which produce the desired space between the roller we provided at each side with a ledge 26, which is engaged by a cutout portion 27 of the squeegee, and a set screw 28 in the squeegee holds the same in the proper spaced relation with respect to the plate.

In Fig. '8, I have shown the squeegee pro- 'vided at the sides with handle portions 29 to facilitate the operation of the same.

In the construction illustrated in Fig. 9, I have provided a plate which is movable longitudinally upon a rack 30 by means of gears 31 and mounted above the same upon a stationary support 32 is provided a squeegee 33, the ends of which engage the raised sides 34 of the plate to space the squeegee from the plate. This space may be regulated by raising and lowering the squeegee with respect to the plate by means of a set screw 35.

In Figs. 10 and 11, I have shown a still further modified form of construction for regulating the thickness of the leaf. This strips, and by movement of the same the upper strips may be raised or lowered as desired.

With the use of my improved construc tion, a very superior form of imitation gold leaf may be produced, which will not tarnish, is very durable, and lends itself readily to the uses intended.

I have illustrated preferred and satisfactation metallic leaf, which consists in subjecting the material from which the imitation gold leaf is formed, to the action of two highly polished metallic surfaces, one moved continuously in respcct'to the other, with the material,tlierebetwecn, for spreading the material to a metallic leaf on one of the surfaces, and allowing it to dry thereon to form a leaf.

' 2. An improved method of producing imitation' metallic leaf, which consists in placing the material from which the imitation gold leaf is formed, upon a highly polished flat surface, and then subjectingthe material to the action of a highly polished sur- 'face passing over the material between the polished surfaces, for spreading the mate rial on the flat surface in a thin layer and allowing it to dry, to form a metallic leaf. In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
