Such a device and method often result in a non-uniformV application of the metallic strips, in their occasional creasing and tearing and not infrequently in the deposition of spots and streaks of the oily substance on the strips thus applied.

With theforegoing in View, my invention provides a means and a method for applying the metallic strips or sheets in a strictly uniform manner, for avoiding the creasing and the tearing of the strips incident to the employment of the old method and for eliminating entirely the oily spots and streaks that may develop because of the use of an adhesive substance applied to the gauze of the frame.

The spirit level I is mounted on one side of the frame I and enables the operator to hold theY device in a horizontal plane when the metallic leaf 8 is to be applied to the material 9. Two or more set screws I0 and I0 are attached to the lower part of one of the sides of the frame I for the purpose of enabling the operator to rest the device on the material 9 that is to be covered with the metallic leaves 8 and at the same time of preventing him,

zontal plane by means of the level l', from scufing or otherwise disarranging the metallic leaves already deposited.

The manner in which my device can be utilized becomes obvious when the operation is more fully described. The transparent non-conducting bottom 2 is rubbed either with the hand or with a cloth of such a material as to produce in it a. state of electrication. AsL illustrative of the electrified condition of the bottom 2^when`it is constructed of glass, a cloth of silk moved briskly gently upon the leaf 8 of silver, gold or any other metallic substance, the leaf is immediately attracted to the bottom 2 and lies in a smooth, unwrinkled expanse over its surface. The device is then carried to the material 9 which is to be covered with the metallic strips. Such a movement is most easily executed in spite of the extremely fragile nature of the metallic leaf. If the material 9, for example leather, has been covered with a suitable adhesive substance then the operator WhetherV he is skilled or inexperienced merely presses the block 6 Yagainst the screen 3 after the device has been correctly placed over the -area of the material 9. The contact of the metallic sheet 8 with .the moist leather 9 and of the operators finger with the` block 6 causes a discharge of the electrification residing on the bottom 2. This resulting discharge of the electrification induces the metallic strip 8 to fall into the desired section on the material 9. After the material 9 has become partly covered with the metallic coa-ting as shown in Figure 6, the operator in working from the left toward the right rests the set screws lll'and I0 of the frame on the leather or other material and, guided by the level 1, adjusts the device to a horizontal plane before the block 6 is pressed to discharge a metallic leaf. In this way leaf after leaf of the thin metal can be quickly, uniformly 'and neatly deposited without in any manner disturbing leaves already laid or without causing the loss of leaves incident to the use of the old method when air currents and inexperi` ence on the part of the operator proved costly.

In Figure is shown a modified form of my ln-p scribed with the exception of the centrally placed y screen 3 as shown in Figures l, '2, v3 and 4. The

modified device is designed to' pick up the metallic leaf 8 along the edge 9' in a manner similar In all other respects the modified to that explained for the preferred form. Although the use of oil or glycerine is obviated, yet the operator must acquire the diiicult technique of flipping the device through the air before he deposits the leaf 8', intact and un- Wrinkled, upon the desired place on the leather 9.

While the constructions as shown and described are the preferred embodiment of my device,` nevertheless the same may be modified inv detail Without departing from the spirit and the l scope of the invention as defined in the annexed over its surface sets up a positive electrification in the bottom 2. When the device is then pressed v claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A device for applying mechanically thin meay tranparent 4and nonconducting medium attached to the4 under side of said frame, a screen covering a cut out section of said medium and la means for releasing a metallic sheet from said medium.

2. A device vfor applying mechanically thin metallic sheets comprising in combination a frame, a screen attached to the under side of said frame, a transparent` and nonconducting medium attached to and covering a portion of said screen and a means for releasing a metallic sheet from said medium.

3. A device for applying mechanically thin metallic sheets comprising in combination a frame, a. transparent and nonconducting medium Vattached to the under side of said frame, a screen covering a cutout section of said medium, aspring clip secured rigidly to the sides of said frame, a block positioned intermediate the ends of said spring clip and adapted to make contact with said screen for the release of a metallic sheet, a. level attached to a side of said frame and adapted to determine the horizontality of said frame, and set screws attached to a side of said frame and adapted to hold said frame in a horizontal plane. v

4. A device for applying mechanically thin metallic sheets comprising in combination a frame, a screen attached to the under side of said frame, a transparent and nonconducting medium attached to and covering a portion of said screen, a spring clip secured rigidly to the sides of said frame, a block positioned intermediate the ends of said spring 'clip and adapted to make contact with said screen for the release of a metallicsheet, a level attached to a side of said frame and adapted to determine the horizontality of said frame, and set screws attached to a side of said frame and adapted to hold said frame in a horizontal plane.
