ERNEST DE PASS, of the Office for British and Foreign Patents, 68 Fleet Street,
in the City of London, Patent Agent, IMPROVEMENTS IN MACHINES FOR CLEANING
INTESTINES. Communicated to ime from abroad by Sigmund Oppenheimer, of
the City and State of New York, in the United States of America,
"
This invention relates to improvements in machines for cleaning intestines, for
what is known as " CASCs for sausages, &c; and the nature thereof relates to a
pair of double rotary scrapers arranged in relation to a revolving cylinder which
may be so adjusted as to clean the entrails. It also prevents the coiling up of a
tissue around the scrapers, which is found associated with the intestines.
Operating in connection with the said mechanism is a pair of elastic rollers,
between which the intestine passes from the cylinder, and by which the remaining
unclean deposits are entirely removed.
The revolving cylinder is secured to a shaft mounted in a suitable frame work,
and receives its motion from a driving wheel by means of gear wheels, one of
which is upon the driving shaft and the other upon the cylinder shaft.
To the front end of the machine are attached two standards carrying a pivoted
frame in which are mounted two shafts carrying each a pulley. Around these
pulleys passes a belt which extends under a loose pulley on the cylinder shaft,
thence round the driving wheel. By this belting of the pulleys with the driving
wheel motion is conveyed to their shafts and to the revolving scrapers, which
scrapers are provided with a series of wings for the purpose hereinafter described.
In cleaning the intestines by this machine, (they first being prepared in the

page_text: usual way,) one or more is singly fed in between the cylinder and the scraper.
The cylinder revolves in one direction and the scraper reversely to it, and as the
entrail is carried along by the cylinder to the elastic rollers, the scraper scrapes or
sweeps out the feculent deposit and matter from the interior, and also scrapes off
the integument which covers the exterior of the entrail.
By means of the second or auxiliary scraper, the exterior membrane is prevented
from. coiling around the first or scraper proper. As this membrane is light and
clastic it readily coils or folds about the scraper proper, and is readily taken up
by its wings and wrapped around them, rendering the scraper proper less efficient
in acting upon the intestines. The purpose of the second or auxiliary scraper is
to prevent this membrane from coiling around and entangling the scraper proper.
As the membrane is removed by the scraper proper, the tendency in removing it
is to carry it up around its wings. To avoid this the auxiliary scraper is provided
with a larger number of wings than the scraper proper, and is arranged to admit
of its wings running closely to but not in contact with the wings of the scraper
proper. The rotation of the auxiliary scraper is in such direction and revolves so
much faster than that of the scraper proper, that the said membrane, as it is
taken off and carried up in the direction of its rotation is met by the wings of the
auxiliary scraper and scraped or swept off from the wings of the scraper proper.
Hence the scraper proper is freed from any entanglement of the membrane by the
action of the auxiliary scraper. Those scrapers may be adjusted by means of a
screw which so engages the cross bar of the frame with a pivotal connection at its
lower end that by turning the screw, the frame which is pivoted to the standards
will vibrate or move upon its pivots to or from the cylinder, carrying the scrapers
correspondingly. Thus the scrapers may be brought more or less close to the face
of the cylinder, as the nature of the case may require.
A guard, placed in front of the cylinder, prevents the entrails from being
displaced or thrown up and entangled by the cylinder.
By the action of the elastic rollers the intestines are drawn over the cylinder
between the scrapers, so that no feeding or guiding is required after the intestines
are taken up by said rollers.
A jet of water, thrown upon the rollers, prevents the intestines from sticking to
the rollers in passing through between them.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Ernest de Pass in the Great Seal Patent Office on the 10th January
1883.

in the City of London, Patent Agent IMPROVEMENTS IN MACHINES FOR CLEANING
INTESTINES Communicated to me from abroad by Sigmund Oppenheimer, of
the City and State of New York, in the United States of America
This Invention relates to a machine for cleaning intestines for what is known
26 cases " for sausages, &c; and the nature thereof relates to a pair of doublé

page_text: rotary scrapers arranged in relation to a revolving cylinder which may be so
adjusted as to clean the entrails. It also prevents the coiling up of a tissue around
the scrapers, which is found associated with the intestines.
Operating in connection with the said mechanism is a pair of elastic rollers,
between which the intestine passes from the cylinder, and by which the remaining
unclean deposits are entirely removed.
I now proceed, with reference to the accompanying drawings, to fully describe
this Invention.
Figure 1 is a side view; Fig. 2, a plan; Fig. 3 an end viow, and Fig. 4, a
sectional view.
Like letters of reference indicate like parts in all the figures.
A general view of the machine is seen in Figs. 1 and 2, in which
:
A is the driving-wheel, which is mounted upon the shaft A¹ journaled in boxes'
secured to the frame B. Upon this shaft is secured a gear-wheel C, which gears
into the wheel D, and also the pinion E. This pinion is upon the shaft of the
clastic roller F (Fig. 2). At the outer end of the shaft is keyed the pinion G,
which takes into the pinion H, which is mounted upon the shaft, to which the
roller I is attached. The shafts of the rollers have their bearings in adjustablo
boxes supported by the arms J J to the frame.
The boxes are moved and set, and the rollers F, I, are adjusted correspondingly
by means of the set-screws K, which screw into the arms and connect with tho
boxes.
The gear-wheel D is attached to the shaft L, which is journaled in boxes secured
to the frame, as seen in the drawings. The cylinder M is also secured to tho said
shaft L and this cylinder receives its motion from the driving wheel by means of
the gearing CD, one pinion of which is upon the driving shaft A' and the other
upon the cylinder-shaft L, Fig. 2.
To the front end of the machine are attached two standards Q, Q, at the upper
ends of which is pivoted the frame N at N¹. (Figs. 1 and 2). In this frame aro
journaled the shafts OO, and upon each shaft is secured a pulley P, as seen in
Figs. 2 and 3. Around these pulleys passes a belt R, which extends under tho
loose pulley S, on the shaft L, thence around the driving wheel A. By this belting
of the pulleys P, P, with the driving wheel, motion is conveyed to the shafts 0 0,
and also to the revolving scrapers T, T', which are secured to and supported by
the shafts 0 0.
The scrapers are provided with a series of wings a, b, for a purpose hereinafter
described.
By the construction and arrangement of the soveral described parts the working
mechanism operates conjointly by connection with the driving wheel,
In cleaning the intestines by this machine (they first being prepared in the usual
way), one or more is singly fed in between the cylinder M and the rotary
scraper T. The cylinder revolves in the direction of the arrow and the scraper T¹
reversely to it, and as the entrail is carried along by the cylinder to the elastic
rollers F, I, the scraper T' scrapes or sweeps out the feculent deposit and mattor
from the interior, and also scrapes off the integument which covers the exterior of
the entrail.
By means of the auxiliary revolving scraper T the exterior membrano is
prevented from coiling around the scraper T¹. As this membrane is light and
elastic it readily coils or folds about the scraper T¹, and is readily taken up by the
wings b of the scraper and wrapped around them, rendering the scraper T₁ less
efficient in acting upon the intestines. The purpose of the auxiliary scraper T is
to prevent this membrane from coiling around and becoming entangled with the
scraper. As the membrane is removed by the scraper T', the tendency in removing
it is to carry it up around the wings b. To avoid this the scraper T is provided
with a larger number of wings than the scraper T', and is arranged to admit of the
wings a running closely to, but not in contact with the wings b of the scraper T'.
The rotation of the scraper T is in such direction and revolves so much faster than

page_text: "
that of the scraper T', that the said membrane, as it is taken off and carried up in
the direction of its rotation, is met by the wings a, and scraped or swept off from
the wings b. Hence the scraper T¹ is freed from any entanglement of the membrane
by the action of the scraper T. These scrapers may be adjusted to or from the
face of the cylinder by means of the gauge-screw U, which so engages the cross
bar of the frame N with a pivotal connection at its lower end that, by turning
the screw, the frame, which is pivoted to standards Q, Q, will vibrate, or move, upon
its pivots to or from the cylinder carrying the scrapers correspondingly. Thus the
scrapers may be brought more or less close to the face of the cylinder, as the nature
of the case may require.
In front of the cylinder is placed a guard V (Figs. 3 and 4) to prevent the
entrails from being displaced or thrown up and entangled by the cylinder.
The entrails are received from the cylinder between the two clastic rollers FI
(Fig. 2) the pressure of them upon the intestines being such as to effectually force
out all the fecal sediment or dregs which may not have been removed by the
scraper.
More or less pressure may be given to the rollers by means of the adjusting
screws K K acting upon the movable boxes of the roller-shaft.
By the action of the elastic rollers the intestines are drawn over the cylinder
between the scrapers, so that no feeding or guiding is required after the intestines
are taken up by said rollers. A jet of water is thrown upon the rollers by means
of a pipe W, or by equivalent means, which prevents the intestines from sticking
to the rollers in passing through between them.
Having now described the nature of the said Invention, and in what manner the
same is to be performed, I declare that I claim,
1. The machine for cleaning intestines having its parts arranged, combined, and
.operating substantially as herein described, and shewn in the drawings.
2. In machines for cleaning intestines, the auxiliary rotary scraper arranged in
relation to the scraper T', cach journaled in a pivotal frame and operating
conjointly in connection with the cylinder M, substantially as and for the purpose
described.
3. The frame N having a pivotal adjustment and carrying the rotary scrapers,
with their pulleys and shafts, in combination with the cylinder M arranged to
co-operate with the elastic rollers substantially as described, and for the purpose
specified.
4. The rotating winged scrapers arranged to revolve conjointly and in different
velocities to cach other, in combination with the pivoted frame N, adjusting-
screw U, and revolving cylinder constructed and arranged in the manner and for
the purpose substantially as described.
In witness whereof I the said Ernest de Pass have hereunto set my hand
and seal this twentyeighth day of December in the year 1882.
