duced and is highly efficient in use.

Another object of the invention is the provision of an improved method for making incense whereby said incense may be provided with invisible characters which will develop and become visible when the incense is burned.

Other objects will appear hereinafter.

The invention consists in the improved incense and in the methods of procedure hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in which Fig. 1 is a top plan view of a sheet of incense blocks employed in carrying on the improved method of manufacture;

Fig. 2 an end view of said sheet;

Fig. 3 a detailed view showing said sheet in position on a magnetic table with a magnetic stencil positioned thereon for the application of an invisible material which will become visible upon combustion of the incense blocks;

Fig. 4 a partial top plan view of one corner of said magnetic table with upper portions broken away to reveal the underlying portions;

Fig. 5 a front view of a completed block of incense shown as mounted in position for combustion;

Fig. 6 a side view corresponding with Fig. 5; and

Fig. 7 a partial plan view of a sheet of incense material sub-divided into blocks of triangular form.

In carrying on my improved process, I first prepare a paste consisting of gum tragacanth powder 3 02., saltpeter 6 grams, fine charcoal 5% lbs., coarse charcoal 1b., gum olibanum powder 5 oz., and one gallon of water. These materials are thoroughly mixed together and, in the proportions indicated, will form a paste capable of being rolled or spread into a flat sheet.

A rectangular sheet of the paste is then formed of suitable or desirable thickness and is subdivided into a plurality of rectangular blocks It, said blocks being defined by slits which do not extend entirely through the sheet, thereby only partially severing the blocks from the sheet, as indicated in Figs. 1 and 2. The sheet thus prepared is then placed on a metal screen I l of a size somewhat larger than the sheet of blocks to facilitate handling. The sheet is then permitted to dry and the desired perfume sprinkled or sprayed over the same. The sheet of blocks, still resting on the screen I l, is then placed upon a magnetic table I2 and a magnetic stencil l3 placed over said sheet of blocks. is preferably made of steel, which will be attracted by the magnetic table, and thereby held or pressed into close and intimate contact with the upper flat surface of the sheet of blocks. The

stencil I3 is out therethrough in desired char- 10* acters, words or letters M which it is desired to place upon the individual blocks, a separate set of characters, words or letters being provided for each block l0 in the sheet of incense material. In the instance illustrated, the words Expect a 15 change for the better are thus cut through the stencil for each block [0 in the sheet.

In order to insure proper registration of the stencil characters with the underlying blocks In, one edge of the stencil I3 is provided with a de- 20 pending gauge lip I5 so arranged that when in I contact with one edge of the sheet of blocks, the stencil characters will properly register with the underlying blocks, as indicated in Fig. 4. Then the exposed portions of the blocks are sprayed 25 with a solution of copper sulphate by means of an air brush or other suitable atomizer, the finely divided or atomized particles of the solution passing freely through the openings in the stencil and falling upon the underlying surface 30 of the blocks.

Owing to the minute quantity of the copper sulphate solution contained in each atomized particle thereof, the solution will be immediately absorbed by the more or less porous bodies of the blocks, and thus any tendency of the solution to spread or run under the edges of the stencil will be prevented. In this way clear cut characters, letters or words will be deposited on the surfaces of the blocks. The copper sulphate solution thus deposited is invisible, but when the incense blocks are consumed or burned, the copper sulphate in the solution will be changed by the combustion into a visible compound, which I understand is copper oxide. In any event, when the incense blocks are consumed, the words or characters outlined thereon by the atomized spray will become visible.

After the spraying operation is completed, the sheets of blocks are removed from the magnetic table, permitted to dry, and then are broken from the sheet into individual blocks and are ready for use.

In order to facilitate the combustion of the blocks so as to present the characters or words The stencil I3 5 forwardly or on the face of the consumed block, the marks I6 are placed on one or more front corners of the blocks to indicate which surface is the front surface of the block.

In Figs. and 6 I have illustrated a block ID supported on a suitable easel or rest IT for such consumption, Fig. 5 illustrating the block after consumption and therefore showing the words Expect a change for the better which will mysteriously appear on the face of the block as it is being consumed.

In Fig. 7 I have shown the sheet of material divided into a plurality of triangular blocks l8,

which triangular blocks are recommended for use for home consumption and where excessive. heat of combustion is likely to cause damage or inconvenience. Naturally these triangular blocks will always be positioned with oneapex extending. upwardly, and naturally it is this upwardly extending apex which is ignited. As the combustion slowly proceeds, the heat of combustion will be absorbed and distributed by the larger lower unconsumed portion of the block, and thereby the intensity of the heat of combustion dissipated to a considerable extent without doing any damage or causing any inconvenience.

While I have illustrated and described the preferred embodiment of the invention and the preferred method of making the incense, these are capable of variation and modification without departing from the spirit of the invention.

I therefore do not wish to be limited to the precise details disclosed, but desire to avail myself of such variations and modifications as fall within the scope of the appended claims.

I claim: 5

1. The method of making incense which consists in forming a sheet of combustible porous material; then partially severing said sheet into a plurality of blocks; then placing said sheet on a metallic screen; then placing said sheet on a 10 magnetic table with a magnetic stencil arranged over the sheet; and then spraying the exposed portions of said sheet with a liquid containing a chemical rendered visible by combustion of said body.

2. The method of making incense which consists in forming a sheet of combustible porous material; then partially severing said sheet into a plurality of triangular blocks; placing said sheet on a metallic screen; then placing said sheet on a magnetic table with a magnetic stencil arranged over the sheet; and then spraying the exposed portions of said sheet with a liquid containing a chemical rendered visible by combustion of said body.

3. An article of manufacture comprising a porous body of combustible incense having a flat surface marked with sharply outlined characters in heat-responsive sympathetic ink.
