UNITED STATES LEON M. HABWOOD, OF SPRINGFTELD, MASSACHUSETTS.

DEVICE FOR- ARPLYING METALLIC LEAF.

Application filed February 25, 1924. Serial No. 894,986.

To all whom it may concern:

Be it known that I, LEON M. HAnwooD, a citizen of the United States,'residing at Springfield, in the county of Hampden and State of h lassachusetts, have invented new and useful Improvements in Devices for Applying Metallic Leaf, of which the following is a specification.

This invention relates to improvements in devices for applying metallic leaf, such as gold leaf and the like.

The invention, while capable of general application, is particularly suitable for applying gold leaf and the like to glass. According to the practice, heretofore prevailing in this art, the leaf has been used in book form and the operator first manually cuts, from a leaf in the book, a piece of the desired size and shape, after which the cut piece is transferred from the book to the prepared surface of the glass wlth the aid of a tip brush, usually first electrified by rubbing it through the operators hair.

The general object of this invention is to provide a device whereby the metallic leaf may be withdrawn from the package and transferred to the glass in a convenient and expeditious manner and in a manner calculated to avoid injury to, and undue waste of, the leaf.

In carrying out my invention I make use of the so-called roll package of metallic leaf. That is, the leaf, preferably although not necessarily, is arranged in separated sections upon a suitable supporting strip, which usually consists of tissue paper or the like, and the strip, with the sections of metallic leaf thereon, is wound into roll form.

According to my invention, I provide means for supporting such a package and guiding devices over which a length of the supporting strip may be withdrawn. The invention contemplates an arrangement wehereby a length of the supporting strip may be drawn out, and preferably held under tension, and means whereby the operator may conveniently hold such drawn out portion in closely adjacent relation to the glass, which, if suitably pre pared. is moist and causes the leaf to jump from the supporting strip to the glass. The characteristic feature of the invention consists in an arrangement whereby the position of the metallic leaf section on the supporting strip may be observed through the supporting strip, in order to enable the operator to properly locate the leaf relatively to the glass before its transfer.

Other objects and advantages will appear in the following description and in the illustrative embodiment of the invention in the accompanying drawings, in which Fig. 1 is a side elevational view of a device embodying my invention; and

'Fig. 2 is an elevational view taken at right angles and showing the device in the same way in which it would be viewed by the operator during the operation of applying a section of the leaf to a glass.

Referring to these drawings; the device embodies a suitable frame, herein shown as a side bar 5, and suitable means whereby the frame, and other parts carried thereby, may be convenientlyheld by an operator. As shown, a handle 6, fixed to frame'5, is provided for this purpose.

Also fixed to frame 5, and on the opposite side from handle 6, is a stud 7 which functions as a means for rotatably supporting a roll package 8 of metallic leaf. This stud is made long enough to receive packages of various widths. In the case illustrated, a narrow package is used and a spacer 9, loose on stud 7, is provided between the package 8 and a nut 10 which is threaded on the outer end of the stud. By preference, suitable tensioning means are provided to create a drag upon the rotation of package 8 and, as herein exemplified, two plates 11 are used for this purpose, one on each sideof the package and contiguous there with. These plates are received on stud 7 and, by turning up 'nut 10, they may be pressed against opposite side faces of the package with suflicient pressure to create the desired drag.

The package 8, as above set forth, includes a supporting strip 12, usually tissue paper or the like, on which the metallic leaf is placed, the whole being then wound into the roll form shown. By preference, I provide the leaf in sections 13 which are disposed in longitudinally separated relation in the supporting strip 12. This arrangement avoids cutting of the leaf but it is within the province of the invention to provide a continuous metallic leaf and cut it on the supporting strip according to requirements.

The end of the supporting strip passes from the roll 8 over a guide 14 and thence in B") ill) to a guide 15, these guides ;-being 'both mounted on frame 5 and projecting therefrom in the same direction as stud 7 and in parallel relation therewith. The guides 14: and 15 may be constructed in any suitable manner and, as shown, the guide 14 consists of a rubber roll rotatable on a stud 16 fixed to frame 5 and the guide 15 consists of a rubber sleeve applied around two pins 17 fixed to frame 5. Cooperating with guide 15 is any suitable tensioning device, herein shown as a rubber sleeve 18, yieldingly held against guide 15 in any suitable way, as by an elastic band 19, which encompasses the guide 15 and extends through the interior of sleeve 18, the latter being slit at 20 to permit this arrangement.

The supporting strip 12 is passed between , members 15 and 18 and these members cooperate to grip it and yieldingly hold it in any position to which it may be drawn. The devices 11 create a drag tending to resist movement of roll 8. Consequently as the free end of strip 12 is pulled to unwind a length of the supporting strip, the latter, or at least that portion between the guides 14: and 15, is tensioned. The operator pulls out the strip 12 until the metallic leaf section 13 is observed between the guides 14 and 15. He then holds the device, as by handle 6 or otherwise, in closely adjacent relation to the glass to which the leaf is to be applied. Then, if the glass is moistened or prepared to receive the leaf, the section 13 will be attracted to the glass and automatically transferred from the supporting strip 12.

The important feature of the arrangement described is that there is nothing to prevent the operator observing through the supporting strip 12 the position of the metallic leaf on the opposite side thereof. The simplest way of obtaining this result, but not necessarily the only way, is by the use of a leleton frame, such as above described, whereby no parts overlie that portion of the strip disposed betweenguides l4 and 15.

The invention has been disclosed herein, in an embodiment at present preferred, for

illustrative purposes but the scope of the invention is defined by the appended claims rather than by the foregoing description.

7 hat I claim is r 1. A hand operated device for applying metallic leaf comprising, a frame provided with means for supporting a package roll of metallic leaf, and guiding means for directing the supporting strip and the leaf thereon, as it is withdrawn from the roll, said guiding means including two spaced members so arranged with respect to said frame that the position of the leaf between frame that the position of the leaf between. the two members may be determined from i the opposite face of the strip from that which supports the metallic leaf and the leaf may be deposited from the face of the supporting strip between the two members,

and means for tensioning the supporting strip across the guiding means.

3. A hand operated tool for applying metallic leaf, comprising, a side frame, a member projecting therefrom to support a package roll of metallic leaf, two spaced parallel members projecting from said frame in the same direction as the first named member and over which the supporting strip may be drawn leaving a portion of the strip exposed between the two last named members and through which portion the position of the leaf may be observed prior to depositing of the leaf.

4. A hand operated device for applying metallic leaf comprising, a frame provided with means for supporting a package roll of metallic leaf, and adapted tobe supported in proximity tothe surface on which the leaf is to be deposited, guiding means for directing a portion of the supporting strip of the package roll so that the leaf carried by one side of the strip may be positioned adjacent said surface, said guiding means being so arranged that the position v of the leaf on said portion of the strip may be observed through the strip, and .means to tension said portion of the supporting strip.

5. A hand operated tool for metallic leaf, comprising, a frame provided with means for supporting a package roll of metallic leaf, and means carried by said frame whereby a length of the supporting strip as it is withdrawn from the roll may H be stretched taut between two spaced points with the leaf exposed on one face of the strip for transfer to the surface to be gilded and the position of the leaf on the strip applying 7 visible through the strip from the opposite v face thereof.

In testimony whereof I have aflixed my signature.

LEON M. HAR-VVOOD.
