To all whom it may concern:

Be it known that 1, WASHINGTON BERRY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in the Art of Making Soapv (lakes Provided with Inserts, of which the following is a specification.

My invention relates to improvements in the art of manufacturing cakes of soap, eachof which cakes shall be provided with an insert either for the purpose of giving buoyancy to the soap, or for receiving advertising matter,'or for modifying the color of the soap, or to provide a suitable handpiece for carrying the soap until entirely consumed, or for any other suitable purpose. In the practical development of this art numerous difficulties have been encountered which have seriously interfered with the commercial establishment of this art. In order to comply with practical requirements, it is necessary that when completed each cake of soap shall contain an insert which shall be centrally located in the soap cake and that the insert, it made of wood to give buoyancy to the soap, shall be so treated or protected that the alkalies of the soap and the tannin andlike elements in the wood shall not combine either to injuriously afiect the soap, or to so discolor the wood as to make it unsightly in case the wood is used in a transparent soap, or to make the advertising matter thereon indistinct, or to afiect the color of the soap in case it is a' tinted transparent soap. It is further necessary that means shall be provided to permit the rising of air-bubbles through the liquid soap in the mold, which might otherwise gather adjacent to the inserts and render the. soap spongy in spots, unsightly, and unsalable. It is further necessary that the inserts shall be so arranged in the mold that when the soap has hardened about the inserts it may be automatically cut into cakes, which shall'be out apart at a point equidistant between every two inserts. To provide a process which shall meet all these requirements in a practical and commercial manner'is the primary object of my present invention. This and such other objects as may hereinafterappear areat-tained by the process hereinafter described, which may be conveniently practiced in connection with the devices shown in the accompanying drawings, in which-- Fignre 1 is a longitudinal sectional view of an insert setting or impaling machine. Fig. 2 is a cross-sectional view of the same machine. Fig.3 is an elevation of an insert-supporting barsupplied with a plurality of inserts. Fig. 4 is a sectional view of a convenient form of mold. Fig.5isanenlargeddetailthereof. Fig.' 6 is an end elevation of a rack containing a plurality ofmolds. Fig. 7 is afront view thereof. Fig. 8 is a longitudinal section through armachine for removing the bars of soap from the molds.

Fig. 9 is a similar section showing a bar of soap forced into the receiving-cylinder. Fig. 10 is a cross sectional view on the line 10 10 of Fig. 9 looking in the direction indicated by the arrows. Fig. 11 is a like view on the line 11 11 of Fig. 9 looking in the direction indicated by the-arrows. Fig. 12 is a detail showing a pivoted knife in connec' tion with a perforated diaphragm which may be used to clean the surface of the bar of soap as it is removed from the mold and to give it a brilliant and attractive appearance. Like letters of reference indicate the same parts in the several figures of the drawings. Starting with the wooden inserts, I first treat or prepare these inserts so as to prevent any undesirable combination between the elements contained in the soap and the elementscontained in the wood of which the insert is formed. This treatment consists in coating or sizing the inserts in any conven ient; or suitable manner. Ihave; however, obtained the best results by putting a considerable. number of inserts .into a revolnble tumbler, through which a blast of air is di-' rected, andin then putting in 'thetumbler, with the inserts, a small quantity of ricestarch, obtained by boiling rice-kernels in water to a soft pulp and in then straining the same through a sieve of fine mesh, the pasty semiliquid product which passes through the mesh being what I have termed rice-starch. When the inserts are removed from the tumbler, it will be found that each insert is thoroughly sized with a substantially uniform too but very thin coating of rice-starch, which has at the same time been dried thereon by the air-current passing through the tumbler. I have found that this sizing affords a sufficient coating between the wood of the insert and the soap surrounding the insert to prevent any discoloration of the insert by the elements contained in the soap and to prevent any undesirable combination in the soap of the soap element with the tannin or other elements of the wood. At the same time this coating is not perceptible to the eye after the soap has been cast around the insert.

If it is desired to print advertisingmatter upon the inserts, this may be done either before or after sizing; but I prefer sizing the inserts after the advertising matter has been printed thereon, thereby providing a protective coating between the ink and the soap. The next step relates to means for so arranging the inserts A in the mold that they shall be in axial alinement with each other and shall be equidistant from each other. This result may be conveniently achieved by means of the machine shown in Figs. 1 and 2, which machine comprises a spacing-trough B, having converging walls and provided with spacing-blocks O. The inserts may be quickly placed between the spacing-blocks 0, each insert being automatically held adjacent to one spacing-block by a spring upon the opposite face of the next adjacent spacingblock. This insures the arrangement of the inserts at an equal distance from each other,

while the converging walls of the trough upon which the edges of the inserts rest automatically bring the inserts into axial alinement with each other.

The impaling-machine is provided with a Verticallyreciprocating cross head D, ar' ranged above the trough and provided with means for removably receiving an insert-supporting bar E. This insert-supporting bar is provided with a plurality of impaling-pins 6, extending from one side thereof and in alinement with each other. When the pin-supporting bar is locked in the cross-head, it is arranged above and in alinement with the inserts in the spacing-trough, the impalingpins pointing downwardly toward the inserts and being so arranged '.that each impalingpin is directly above one of the inserts in the trough. Thereupon by a quick downward movement of the cross-head, which may be actuated in any convenient manner, each of the impaling-pins upon the insert-supporting bar is driven into the edge of one of the inserts without disturbing either the spacing or alinement of the inserts in the trough. The cross-head is now returned to its original position, carrying with it the insert-supporting bar, each pin of which now carries an insert, as shown in Fig. 3. The insert-supporting bar is removed from the cross-head and is inserted in a longitudinal recess formed at one side of the mold F, (see Fig. 6,) the impaling-pins projectinginto the mold through cake.

the slotfand supporting the inserts centrally in the mold.

The mold F is preferably open at both the upper and lower ends, the lower end being closed when the liquid soap is poured into the mold in any convenient manner, preferably by means of a rubber pad or other stopper G, upon which the lower end of the mold rests, the lower end of the mold sinking into the rubber to make a sufficiently tight joint at the lower end of the mold. So, also, the lower end of the mold may be sunk into a sheet of soap or the like.

Having arranged the insert-supporting bar in position in the mold, I next set the mold in a racksuch, for instance, as H. (Shown in Figs. 6 and 7.) Any convenient device may be used, however, which permits of the mold being inclined at such an angle that the air-bubbles rising through the liquid soap when the soap has been poured into the mold may escape from the under sides of the inserts, as shown in Figs. at and 5. Unless the mold is so inclined there will be a tendency for air-bubbles to form and to adhere to the under sides of the inserts enough to entirely destroy the commercial value of the soap The hot liquid soap is now poured into the mold, completely surrounding the inserts. The air-bubbles rise freely through the mass of liquid soap owing to the inclined position of the mold, forming a frothy mass at the top of the mold. When the soap has cooled and set sufficiently, the mold is removed from the rubber, soap, or the like which has served to close its lower end, and is placed in the mold clamp I. (Shown in Figs. 8 and 9.) The bar of soap J and the insert-support E,which is still attached to the inserts A, which are now cast inside of the bar of soap, are forced from the mold by means of the plunger K, which is forced into the bottom of the mold and through the mold by any suitable means.

In order to insure having the bar of soap perfectly symmetrical and clean, I provide the perforated diaphragm L, which is attached to the end of the receiving-cylinder M, so that when the bar of soap is forced out of the cylinder M by the plunger it will simultaneously be forced through the perforated diaphragm L, which, having an opening thereth rough slightly less in diameter than the interior diameter of the mold, scrapes a thin film from the convex surface of the bar of soap, so that as the bar passes through the diaphragm L it has a perfectly clean symmetrical surface with a brilliant finish.

The receiving or transfer cylinder M is provided with a slot m, which receives the shanks of the impaling-pins of the insert-supporting bar as the bar of soap and the insert-supporting bar are forced out of the mold. When the bar has been entirely forced from the mold and into the transfer-cylinder, the insert-supporting bar E, which now rests upon the surface of the transfer-cylinder, with the impaling-pins projecting into the cylinder through the narrow slotf, may now be manually removed, thereby withdrawing the impaling-pins from the inserts in the bar of soap. The inclined frothy end of the soap bar,

which was the top of the bar when in the mold, is now out ofi, and we have a symmetrical, clean, and finished bar of soap containing a plurality of inserts arranged therein equidistant from and in proper alinement with each other, so that with a knife or other cutting instrument set at the proper gage the bar is next cut into cakes of soap each of which shall contain a centrally disposed insert. The cakes are now put into any suitable pressing-machine, which not only gives the soap cakes such finish as may be desired, irnsubstantially white wood are used and have been treatedas above described, so as to prevent discoloration, the light reflected therefrom will very materially modify the tinting of the soap, so that a cake of transparent soap of a given color provided with one of these inserts will produce on the eye a very difierent effect from a like cake of the same soap and of the same color not provided with such an insert. Indeed, by the aid of these in-, serts in modifying the color effectI have succeeded in producing color effects which have been heretofore considered practically impossible of attainment. So, of course, the color efiect of the soap may be further modified by using inserts of different tints or colors.

I do not here claim the apparatus shown in the drawings, the same being the subject-matter of my copending applications, filed July 10, 1902, and serially numbered 115,003 and 115,004, respectively.
