Office of the Commissioners of Patents, with his Petition, on the
9th March 1869.
I, HENRY WILLIAM GOLDRING, of Moorgate Street, in the City of
5 London, Merchant, do hereby declare the nature of the said Invention
for "IMPROVED MACHINERY OR APPARATUS FOR THE MANUFACTURE OF SOAP," to
be as follows:-
This Invention consists in performing entirely by mechanical means
the.operations that have heretofore been effected partly by mechanical
0 means and partly by manual labour, and relates to that part of the
operation or process of manufacture called finishing, which takes place
after the rough soap has left the boiling or melting pans. The plan at
present practised of operating in the finishing pan is for the workman
from: time to time with an implement called a crutch to crutch or raise
5 the soap from the bottom and sides of the pan, this operation being
performed in an open pan, or pan without a lid or cover, whilst heat is
applied to the bottom of the pan, the objection to which is that the room
in which the pan is fixed becomes filled with steam, and the soap
splashes over the top of the pan in the act of crutching; moreover, in

page_text: making scented or toilet soap a great portion of the scent employed
passes off and is wasted.
Now the object and intention of this Invention is to remedy these
objections, and to simplify and expedite the above operations, which I
propose to accomplish by the use of a machine or apparatus of the
following construction:-The pan, which is somewhat of the ordinary
shape with a hemispherical dished bottom I surround by a jacket into
which steam is admitted as commonly practised, and at the centre of the
pan I adjust an upright revolving shaft, through which three or more
horizontal rods or bars pass one above the other. These rods or bars are
connected to and revolve by their ends in two upright flat bars of metal,
made of the same shape as the sides and bottom of the pan, against
which they fit nearly close and move freely. The bottoms of the said
bars are firmly connected together by another bar fitting the extreme
bottom part of the pan, and this bar is fixed to the aforesaid upright
shaft, and moves therewith. Into the bottom bar aforesaid I fix a plate
of metal at an angle somewhat like a ploughshare, so that as it revolves
it shall scrape the bottom of the pan and plough up the soap thercon. I
also fix upon the aforesaid horizontal bars near to the upright shaft a
train of wheels, namely, one wheel on each shaft, and intermediate
pinions for driving the said bars in opposite directions, for the purpose
hereafter stated, and upon the uppermost of the aforesaid bars I fix a
bevil pinion, taking or gearing into a bevil wheel fixed across the top of
the pan, the upright shaft passing loosely through the boss of this wheel,
so that as the said upright shaft revolves the teeth of the bevil pinion
rolling in the space between the toeth of the fixed bevil wheel will
impart rotatory motion to the bar on which the bevil pinion is fixed, and
cause rotatory motion of the other bars by the train of wheels before
mentioned. Upon each of the aforesaid rods or bars I fix cutters and
elevators, the cutters being arranged at one side of the upright shaft, and
the elevators at the other side thereof. The cutters, which are formed of
pointed pieces of plate iron like long teeth, are fixed vertically side by
side on each horizontal bar, the points of the cutters in one row passing
between. the spaces between the cutters in the next row. The elevators
consist of horizontal plates of metal fixed to the aforesaid bars one above
the other at right angles to the upright shaft, the said elevators being so
adjusted with respect to each other as to come into action in succession,
that is to say, the soap lifted by the lowermost clevator should be lifted

still higher by the second elevator, and in like manner by the third or
top elevator. During these operations of the share and elevators the
cutters as they revolve in opposite directions will cut or divide and stir
up the soap and other matters used in the manufacture thereof, whether
common soap or scented or toilet soap. The mechanism in the
pan
enclose by a hinged or divided lid or cover, by which escape of the steam
is prevented. I further propose to use a portion of such said lid or cover
for introducing perfume into the pan in manufacturing scented or toilet
soap. For this purpose I employ an inverted T-shaped pipe fixed to the
under side of the said lid. The long arms of this pipe are perforated
with small holes, the said arms extending nearly across the width of the
top of the pan. The short upright arm passes through the lid and serves
as a funnel for introducing the perfume. By these means the perfume is
more perfectly distributed and escape thereof prevented.
