PERCUSSION sTENCrL.

Application' filed- January 27,1922. lseriaiNo. 532,232.

To all whom t may concer/rt Be it known thatI,-'JOHN E. LESTER, a citizen' ofthe United States, and a resident of Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Percussion Stencils, of which the following is a specilication.

My invention relates to devices for printing or impressing upon surfaces various characters or insignia of a legible nature, by causing the temporary adhesion to such surfaces of a dry pulverulent material which is applied to the surface through a suitably perforated stencil-sheet. It is the object of my invention to provide a simple and inexpensive device of this kind, to be used as an advertising novelty, or as a toy, and capable of embodiment in a neat and attractive form.

In the accompanying drawings Fig. 1 is a front view of a device embodying my invention, Fig. 2 is a side view of the same, and Fig. 3 is a detail vertical section, drawn to an enlarged scale, the section being on the line 3 3 of Fig. 1.

In the illustrated structure I provide a circular and substantially fiat head-member having front and rea- r faces 4 and 5 formed of suitable sheet material such as tough paper. The edges of the sheets 4 and 5 are secured together by suitable means, such as a band 6 of adhesive material, whereby to form between -the intermediate portions of the sheets an enclosed pocket adapted to contain a quantity of pulverulent material 7. The enclosed space may be subdivided into two or more compartments by strips or bands of adhesive material, such as the transversely extending strip 8 indicated in Figs. 1 and 2. The peripheral portion of the head-member may be reinforced by means of a frame-wire 9 disposed between the sheets near the edges thereof, and when the frame-wire is employed the ends thereof are preferably turned downwardly into the neckportion 10 which is attached to the handle 11. The handle is formed by a strip of wood, rectangular in cross-section, provided at one end with a. kerf into which the neck-portion 10 is inserted and secured by means of a rivet 12 extending through the parts transversely of the kerf. Reinforcing strips 13 are provided at the sides of the neck-portion, said strips being inserted in the kerf and secured'by the rivet `12, and the end andilateral redges thereof extending slightly beyond the handle, as" shown.

The front sheet 4 of the head-member is in effect a stencil, being suitably perforated to provide for the egress' of the pulverulent material 7 contained in the pockets, the perforations 14 being very small whereby to prevent too free escape of the powder, and being arranged so as to form any desired characters or design. lVhen the desired design consists of letters or words,such as the words Come to Portland 1925 represented in Fig. 1, the letters and figures appear reversed when viewed from the front, similarly to printing-type. The material 7 may be any innocuous powder, such as talc or precipitated chalk, a material being chosen which has some capacity for adhesion to a slightly rough or unpolished surface when forcibly applied thereto. When the pocket or enclosed space is divided into a plurality of compartments, powder of different colors may be placed in the several compartments, whereby the respective parts of the impressed or stencilled design will appear in the different colors.

The faces of the head-memberl are preferably printed or lithographed with' suitable ornamental or pictorial designs (not represented in the drawing), which serve to mask the stencil design and impart a pleasing appearance to the device as a whole.

The configuration or profile of the headmember need not be circular, although the circular form is probably the simplest and is well adapted, in connection with the pictorial design imprinted upon the surfaces, to represent a Variety of objects, such as an orange, an apple, a persons head, or any similar object having an approximately circular outline.

The use of the article will be apparent. As a toy or amusement device, or as an advertising novelty, the same may be distributed at fairs, Carnivals, expositions, conventions, and other gatherings, the printed designs and the stencilled legends employed being such as may be appropriate for the occasion. The stencil kdesign formed by-the perforations 14 will be legibly impressed temporarily upon the surface of any object against which the front face of the headmember is struck or slapped, the act of percussion being sufficient to cause a small quantity of the contained poWder to pass through each of the perforations and adhere to the surface struck.

Now, having described my invention, what I claim and desire to secure by Letters Patent is:

1. In an article of `the class described, a supporting handle, and a head-member attached to the end thereof, said head-member comprising u pair of sheets united at their peripheral portions to enclose a pocketspace between them, it face of the head-member having perforations therein arranged to orm e design, and pulverulent materiel contained in the pocket-space and percussively displaceable therefrom through the perforate face.

2. In an article as set forth in claim l, a. 'frame-member disposed between the united peripheral portions of the sheets and eX- tended into the handle.

3. In an article as set forth in claim l, means uniting intermediate portions of the pair of sheets to divide the pocket-space into a plurality of compartments.

JOHN E. LESTER.
