Improvements in the Manufacture of Resinous Soap and Apparatus
Therefor.
I, FRITZ ARLEDTER, of Perlen, near Luzern, in the Republic of Switzerland,
Engineer, 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 relates to a process and apparatus for producing resinous soap in
a more expeditious, effective, and on the whole more rational manner than hitherto
employed.
The principle underlying my invention consists in continuously exposing the
lather that ascends in the resin boiler to the mechanical action of a stirring
apparatus fitted with cutting planes or knives, and in simultaneously melting the
particles of resin ascending with the lather by means of a number of slotted or slit
hot metal plates. By these means I effect the division of the resin particles into
atoms and obtain resinous soap the resin of which is liberated resin. At the same
time the expulsion of the gases generated in boiling makes the boiling process
much more thorough and of considerably shorter duration than hitherta."
The boiling apparatus which I make use of in carrying out my process is shown
in the accompanying drawing, in which:-
:-
Figure 1 is a side view of the boiling apparatus; and,
Figures 2, 3, 4 and 5 are detail views of the same.
The resinous soap is made in the usual manner in a boiler a heated indirectly
c is a stirrer formed on the
by steam through the medium of the steam jacket b.
lower end of a shaft d, which is connected to the shaft or spindle fate whilst the
stirrer c is working. A third, shaft or sleeve g rotates around the spindle or shaft f.
The shafts and g are caused to rotate in opposite directions to each other by
means of suitable transmission gear. In the drawing this gear consists of the two
bevel wheels h and i keyed to the upper ends of the shafts and g respectively and
caused to rotate in opposite directions by a third bevel wheel gearing therewith
and operated from a suitable motor through the medium of the belt 7.
A sleeve m is mounted upon the shaft g in such a manner that it rotates with
and can slide up and down on the said shaft. The said sleeve m is connected by a
rod n to a sleeve o which rotates with and can slide on the shaft or spindle f.
Figures 2 and 3 are a side view and a plan view respectively showing how the
sleeve m may be connected to the shaft g. The said shaft is shown square in cross
section, and passes through the sleeve m, which is made square to receive it.
Springs phold the sleeve m in position and by means of the pivoted lever 7 fixed
to the sleeve by means of a loose ring q the sleeve m may be adjusted longitudin-
ally on the shaft g, its adjustment also effecting that of the lower sleeve o on the
shaft f. The rod n connecting the sleeves can be secured at its ends to loose rings s
and t fitted round the sleeves m and o respectively.
Curved arms u, u extend downwards to the same extent from the sleeves m and o
and are provided at their lower ends with plough share shaped irons or knives v, v
and w, w. Figure 4 is a detail plan view of one of these knives shewing it secured

page_text: to its arm u and Figure 5 is a plan view of the whole arrangement of the knives
(here shewn four in number) which rotate with their edges pointing in the
direction of motion. The arms rotate in opposite directions as indicated by the
arrows Figure 5.
x, x, x are fixed metal plates fitted to the boiler a, and preferably adjustable up
and down. The plates are provided with longitudinal slots y as shown in Figure 1.
With the above described apparatus a rapid division of the millions of gas
bubbles will be effected by means of the fixed slotted plates in combination
with the very effective action of the knives , w. By these means the usual rising
of the mass, during the boiling operation, will be considerably reduced, and the
temperature can therefore be raised by the admission of steam whereby the process
is accelerated, while at the same time a thorough separation of the saponified and
non-saponified resin particles is effected. The ascending resin particles constantly
come in contact with the hot metal plates, which melt them and the rotary
motion of the knives, forces them through the slots or slits y and thoroughly
mixes them after they have been separated into atoms. In this way resinous soap
with liberated resin is obtained.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what I
claim is:-
1. The described process for the production of resinous soap, such process con-
sisting in continuously exposing the lather surface of the mass to the mechanical
action of cutting knives to expel generated gas for the purpose of effecting the
thorough boiling of the mass in order to obtain in as short a space of time as possible
resinous soap containing large quantities of liberated resin, substantially as
herein before described.
2. In a process of the kind described in Claim 1, the employment of slotted or
slit plates which, when heated, melt the ascending particles of resin, substantially
as described.
3. The employment for carrying out the process described in Claim 1 of
apparatus comprising a boiler having a number of stirrers with cutting planes or
knives moving in opposite directions between a number of vertical plates provided
with longitudinal slots or slits, the said knives and plates being adjustable to
suit the height of the lather in the boiler, substantially as hereinbefore described
and illustrated in the accompanying drawing.
4. In a boiler for the production of resinous soap of the kind described in
Claim 3, the knives, secured to arms which are fitted to adjustable sleeves m
and o on shafts g and f rotating in opposite directions, and can be adjusted to the
proper height in the boiler a by the lever and sleeve arrangement r, g; m, p, s, n,
t, o, substantially as described and illustrated in the accompanying drawing.
