PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Soap Tablets.
I, FREELAND W. OSTROM, a citizen of the United States, residing at No 160
Barnum Avenue, in the City of Bridgeport, in the County of Fairfield and State of
Connecticut, one of the United States of America, Inventor, do hereby declare the
nature of this invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
My invention has reference to the construction of dies for use in compressing soap
around a suitable anchor, the latter being provided with an eye which extends
laterally beyond the cake of soap, whereby the soap may be attached to a chain,
string or the like, as a precaution against theft, loss, etc.
Furthermore my invention has reference to the hereinafter described method of
providing a soap cake with an internal anchor, whereby said cake may be suspended
from any suitable chain.
In the accompanying drawings :-
Figure 1 is a sectional elevation showing my dies in operative position, a cake of
soap lying upon the lower die preparatory to being compressed.
Figure 2, is a similar view showing the soap compressed between the dies.
Figure 3 is a top plan view of the die-box.
Figure 4 is a perspective showing the relative position of the dies prior to their
operation, and also the contour of their faces.
Figure 5, is a sectional elevation of my invention showing an auxiliary guide
for the anchor eyes, both dies being provided with fins adapted to travel within the
eye-guide.
Figure 6, is a detail perspective of the auxiliary eye-guide, and
Figure 7, is a detail perspective of the die-box.
Similar letters denote like parts in the several figures of the drawing.
A, is the upper die of any suitable shape, and secured, as by set-screw, B, to the
ordinary plunger, C. D, is the die-box mounted on a bed, E, and having a vertical
groove, F. G, is the lower die within said box, and, H, is the usual drive-rod
beneath said die, and by means of which the latter may be elevated within the box.
In preparing the soap for compression between the dies, the anchor, I, is thrust
through the soap cake, K', so that the hook or eye, J, projects beyond said cake,
the soap being of course in a green and plastic state.
A cake of soap thus provided with an anchor is placed upon the lower die with
the anchor eye extending in a vertical plane within the groove, F, as is clearly
shown at Figure 1. The dies are now operated by the ordinary power press
mechanism (not shown) to compress the soap within the die-box, as shown at
Figure 2. While the soap is being carried by the dies, the eye, J, will travel
unobstructed within the groove, F.
If desired, an auxiliary guide, K, may be secured to the top of the box so as to
be in alignment with the groove, F, as shown at Figures 5 and 6, and the object of
such guide would be to correctly centre the soap cake on the lower die by placing
the soap on said die with the anchor eye within the guide. In Figure 7, I have
shown the groove in the die-box chamfered at the top, as shown at b, in order to
insure the free passage of the anchor eye within the groove, but both this chamfering
and the auxiliary guide are precautionary and decidedly not essential, and I do not
therefore wish to be limited or circumscribed thereby.
The die may be provided with fins, L, extending within the groove, F, for the
purpose of affording cleaners for said groove, as shown at Figure 5.

page_text: Of course the shape of the dies and box are immaterial, and may be changed
without departing from the spirit of my invention, the gist of which resides in the
broad idea of two compressing dies operating within a die box, said box or dies
being notched or recessed to accommodate the anchor-eye.

Improvements in the Manufacture of Soap Tablets.
I, FREELAND W. OSTROM a citizen of the United States, residing at No. 160
Barnum Avenue, in the City of Bridgeport in the County of Fairfield and State
of Connecticut, one of the United States of America, Inventor, do hereby declare
the nature of this invention and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement, reference
being had to the drawings accompanying the Provisional Specification :-
My invention has reference to the construction of dies for use in compressing
soap around a suitable anchor, the latter being provided with an eye which extends
laterally beyond the cake of soap, whereby the soap may be attached to a chain
string or the like as a precaution against theft, loss and such like.
Furthermore my invention has reference to the hereinafter described method of
providing a soap cake with an internal anchor, whereby said cake may be suspended
from any suitable chain.
In the drawings ::
:-
Figure 1 is a sectional elevation showing my dies in operative position a cake of
soap lying upon the lower die preparatory to being compressed.
Figure 2, is a similar view showing the soap compressed between the dies.
Figure 3, is a top plan view of the die-box.
Figure 4, is a perspective showing the relative position of the dies prior to their
operation and also the contour of their faces.
Figure 5, is a sectional elevation of my invention showing an auxiliary guide for
the anchor eyes, both dies being provided with fins adapted to, travel within the
eye-guide.
Figure 6, is a detail perspective of the auxiliary eye-guide, and
Figure 7, is a detail perspective of the die-box.
Similar letters denote like parts in the several figures of the drawing.
A, is the upper die of any suitable shape, and secured, as by set-screw B, to the
ordinary plunger C. D, is the die-box mounted on a bed E, and having a vertical
groove F. G, is the lower die within said box, and H, is the usual drive-rod
beneath said die, and by means of which the latter may be elevated within the box.
In preparing the soap for compression between the dies, the anchor I, is thrust
through the soap cake K', so that the hook or eye, J, projects beyond said cake, the
soap being of course in a green and plastic state.
A cake of soap thus provided with an anchor is placed upon the lower die with
the anchor eye extending in a vertical plane within the groove, F, as is clearly
shown at Figure 1. The dies are now operated by the ordinary power press
mechanism (not shown) to compress the soap within the die-box, as shown at
Figure 2. While the soap is being carried by the dies, the eye J will travel
unobstructed within the groove F.
If desired, an auxiliary guide K, may be secured to the top of the box so as to
be in alignment with the groove F, as shown at Figures 5 and 6, and the object of
such guide would be to correctly centre the soap cake on the lower die by placing
the soap on said die with the anchor eye within the guide. In Figure 7 I have
shown the groove in the die-box chamfered at the top, as shown at b, in order to

page_text: ensure the free passage of the anchor eye within the groove, but both this cham-
fering and the auxiliary guide are precautionary and decidedly not essential, and I
do not therefore wish to be limited or circumscribed thereby.
The die may be provided with fins, L, extending within the groove, F, for the
purpose of affording cleaners for said groove as shown at Figure 5.
Of course the shape of the dies and box are immaterial, and may be changed
without departing from the spirit of my invention the gist of which resides in the
broad idea of two compressing dies operating within a die-box, said box or dies being
notched or recessed to accommodate the anchor-eye.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. A device for compressing soap consisting of two dies and a die-box, said box
being notched or recessed, substantially as set forth.
2. The combination with the two dies between which the soap-cake is grasped, of
the die-box within which said cake is forced and compressed by said dies, substan-
tially as set forth.
3. The herein-described device for compressing soap around an anchor, the same
being a pair of dies for compressing the soap and a die-box for confining both dies
and soap.
4. The herein-described means for compressing soap around an internal anchor
having an eye projecting outwardly from the soap, the same consisting of a lower
and an upper die, and a die-box within which said dies are operated, said box
having a vertical longitudinal recess to accommodate the anchor eye during the
compression and vertical movement of the soap cake between said dies, substantially
as shown and set forth.
5. The method of securing an anchor within a cake of soap, the same consisting in
thrusting said anchor within a block of green soap and then compressing said block
into the form of a cake, substantially as set forth.
6. The method of securing an anchor within a cake of soap, consisting in thrusting
the anchor within the soap so that the end of said anchor projects from the soap,
and then compressing the latter within a confined space, substantially as set forth.
