THOMAS WOESLEY AND GEORGE W. DORSEY, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNORS TO THOMAS WORSLEY.

IMPROVED DIE FOR FORMING BARS OF SOAP.

Specification forming part of Letters Patent No. 39,784, dated September V1, ISQB; antedated April 11, 1862.

To all whom it may concern:

Be it known that we, T. WoRsLEY and G. W. DoRsEY, both of Philadelphia., Pennsylvania, have invented a new and useful lmprovement in Dies for Forming Bars of Soap;

' and we do hereby declare the following to be ing in the die a recess communica-ting with a I vessel containing water or other suitable fluid, which surrounds the soap as it is being forced through the die and serves as a lubrlcant, so that the surface of the bar of soap may be smooth and even and free from that torn and ragged appearance which it presents after being forced through a die ot' the ordinary construction. i

In order to enable others to make and use our invention, we will now proceed to describe its construction and operation.

On reference to the accompanying drawings, which form a part ot' this specification, Figure 1 is a vertical section ot' our improved die for forming bars ot' soup; Fig. 2, a front view; Fig. 3 a sectional plan, and Fig. 4 a sectional View drawn to a reduced scale and illustrating the operation of our improvement.

Similar letters referto similar parts throughout the several views.

Our improved die consists ot' a block, B, of cast-iron or other suitable metal, provided with dovetailed flanges a c for fitting intoV dovetailed guides ou the end of the cylinder A, Fig. 4, this cylinder having a pistm or. plunger, D, by means of which the soap g round to a pulpy mass is forced through tlndie. rEhe opening in the die through which the soap has to be forced is of the form best observed in Figs. land 3, the opening being largest at the rear of the die and gradually diminishing in size to the point w, where it is of the same size, or nearly the same size, as the bar of soap to be formed. At this point m the openingis enlarged by the recess w, and is again gradually contracted until it reaches the point y, where the opening is of the samey size, or nearly the same size, as it is at the point and from the point y to the point o of the die the opening is straight. Looking toward the front ofthe die, the opening may be of the shape seen in Fig. 2, or it may be of any other shape to which it is desirable to reduce the soap. i

In the usual dies for forming bars of soap there is a simple tapering opening, through which the soap previously ground and mixed to a pulpy mass is forced. However smooth this opening may be, the surface of the bar is torn, ragged, and uneven-a defect which our improvement has been especially designed to obviate.

It will be observed on reference to Fig. 1 that there is in the die a vertical orifice, d, communicating with the recess w. To the top ot' the die, or to any object adjacent thereto, is secured a vessel containing water, alcohol, or other suitable uid, which is allowed to pass down the oritice d and into the recess w, so that, as the soap is being forced through the die it is surrounded hy duid. As the soap passes from the recess w through the front of the die, it carries with ita portion of the'tluid, which serves as a lubricantand prevents that friction ot' the soap against the inside of the die which causes the ragged and uneven appearance alluded to above.

We claim as ourinvention and desire to secure by Letters Patent- The recess w, formed in the die B and communicating with a vessel containing water or other suitable iiuid, substantially as and for the purpose herein set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.

THOMAS WORSLEY. GEO. W. DORSEY. Witnesses:

PETER B. LEVERING, THOMAS RETE.
