Improvements in Apparatus for Cleaning Intestinal Skin's used for
Covering Sausages and the like.
I, CHARLES FREDERICK AUGUSTUS BITTERLING of 118 Montpellier Road,
Dunkirk in the Borough of Nottingham, Student, do hereby declare the nature
of this invention to be as follows:-
:-
This invention relates to apparatus for cleaning the intestinal skins of animals
used in the manufacture of sausages and the like.
In carrying out this invention each skin is drawn over a preferably metal rod
or stick of a suitable diameter and the fatty portions removed from the exterior
by preferably revolving cutters arranged if desirable above and below the rods
or stick.
The rods or sticks over which the skins are drawn are carried by two or more
rollers arranged parallel to each other and at a suitable distance apart, carried
in bearings secured to or forming part of the framing and provided with corre-
sponding grooves to receive the rods or sticks which are hent into a semicircular
form at those parts so as to fit loosely into the grooves of the rollers and be
retained in position when the rollers are rotated. The skins will be consequently
drawn over the rods or sticks by the action of the said rollers by which they are
carried.
The rods or sticks may be also prevented from lifting by rollers arranged
above if desirable.
At one or more parts between two of the rollers the rods or sticks may be flattened
out so that the skins in passing over are distended and present a flat surface to
a preferably revolving cutter or cutters arranged above and below the rods or
sticks if desirable and carried in bearings secured to or forming part of the
framing. The cutters may be connected by a belt and pulleys or by gearing to
one of the roller spindles the whole of which are connected and simultaneously
operated by belts and pulleys or suitable gearing.
Arranged preferably below each rod or stick with their axes parallel thereto
are preferably two rollers carried in bearings formed in or secured to brackets
connected to the framing, the peripheries of these rollers are set close to the
rods or sticks so as to turn the skins as they move forward and bring any fatty
matter or excrescence into such a position that it will be removed by the cutters.
These rollers may be connected by gearing or other means to one of the
rollers carrying the rods or sticks by means of which suitable motion is imparted
to them.
The first end of the skin may be secured to the rod or stick after passing the
cutters and the remainder drawn over it by the roller or rollers at the rear the
skins being thus turned inside out and delivered into a trough ready for the sub-
sequent operation of cleaning the inside.
For this purpose the skins may be drawn through suitably shaped dies and
between revolving brushes used in connection with a jet or stream of water if
desired, by a roller or rollers on one of which they may be wound.
The rollers and brushes are carried in suitable bearings and may be actuated
simultaneously with the remainder of the apparatus so that both operations may
be performed at the same time on two sets of skins.
Dated this 21st day of January 1892.

Improvements in Apparatus for Cleaning Intestinal Skins used for
Covering Sausages and the like.
I, CHARLES FREDERICK AUGUSTUS BITTERLING, of 118 Montpellier Road,
Dunkirk, in the Borough of Nottingham, Student 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 :-
This invention relates to apparatus for cleaning the intestinal skins of animals
used in the manufacture of sausages and the like.
It will be best understood by reference to the accompanying drawings in which
Fig. 1 is a front elevation
Fig. 2 is a side elevation and
Fig. 3 is a back elevation of apparatus constructed according to my invention.
Like letters indicate like parts throughout the drawings.
In carrying out this invention intestinal skins are automatically drawn over a
preferably metal rod or stick of a suitable shape and diameter and the fatty
portions removed from the exterior by suitably arranged knives.
The rod or stick a over which the skins are drawn is preferably shaped as shown
and is carried by grooved rolls or pulleys b, b and c, c, the rolls b,, are secured
to shafts 23, carried in bearings in the ends of arms d d which are pivotted at d
to an extension of the framing e, the outer ends of the arms and the rolls, b¹ may
be thus raised against the action of springs ². These springs also hold the
rolls, against the rod or stick a.
The rolls c, e c², are secured to corresponding shafts c3 c c carried in
bearings, secured to or forming part of the slide g; the slide g is carried
between the parts e e¹ of the framing and is adjustable vertically by means of the
screw which may be operated by the shaft to which a wheel or crank handle
may be fixed, the movement of the latter being imparted to the former by toothed
gearing h*.
With this arrangement the height of the rolls c, c'e² may be adjusted, they may
also be lowered to allow of the removal of the rod or stick a.
The stick a is formed at a¹ with a flat and broadened part to distend the skin,
it is also provided at that part with two side springs i and a spring to compensate
for variations in the diameter of a skin at different parts.
A cutter its cutting edge forming preferably a segment of a circle is pivotted
centrally at and is arranged with its cutting edge close to the inner face of the
flat part of the rod or stick a, this cutter is secured to a pivot k working in a
bearing secured to the framing e.
The cutter is reciprocated (see Figs. 2 and 3) by means of a crank on the
vertical shaft which crank is connected to an arm secured to the pivot k by a
connecting rod 1.
The position of the cutting edge of the cutter j with reference to the face of the
flat part a of the rod or stick is adjusted by raising or lowering the latter by
means of the adjustable slide g and rolls c, c¹ c².
The vertical shaft is carried in bearing m m¹ secured to the framing e¹ and
bearings n, n', and o, ol, secured to or forming part of an extension of the slide g.
On the lower part of the shaft and between the bearings o, o' is a worm p, engaging
with a worm wheel p' secured to the shaft of the roll c², on the upper end of the
shaft and between the bearings n, n', is a second worm o̟ engaging with a worm
wheel secured to the shaft c³ of the roller č.
The worms p, q, are connected to the shaft 7 by feather-keys and are thus free to
slide on the shaft as the slide 9.and bearings connected thereto are raised or
lowered.
The worm p and wheel p' impart rotary motion to the roll c³, and the worm 9 and

page_text: wheel q' to the roll c, motion is imparted from the latter to the roll b by toothed
wheels u usecured to their respective shafts b².
Rotary motion is also communicated to the rolls cand by an intermediate
pivotted on the slide g, engaging with the toothed wheel and a toothed
secured to the shaft c' of the roll c¹, the wheel u³ also engages with a
pinion
wheel
toothed wheel u' secured to the shaft 3 of the shaft b¹.
The shaft may be provided with a pulley to receive a belt, or may be driven
from a shaft carried in bearings & secured to the base of the framing, to which
shaft a pulley may be secured and the two shafts connected by toothed wheels r²
secured to their respective shafts.
A skin in the process of cleaning passes over the lower end a³ of the rod or
stick a and in an upward direction over the part a round the upper curve and
passes off at the end, the first end of the skin may be secured to the end a
of the rod or stick and the remainder drawn over it, the skin is thus turned
inside out ready for a subsequent operation.
The skin is drawn over the rod or stick by the rotary motion of the rolls b₁c c¹ c²
and in order that they may more readily effect this operation the grooves in the
rolls are preferably lined with india-rubber the surface of which is roughened or
corrugated.
As the fatty excrescences which it is necessary to remove are always on the
inner side of the natural curve of a skin the skin as it is drawn on to the lower
curved part a of the rod or stick will adapt itself to the curve of the stick and the
fatty portions will be thus always brought automatically to the inner side and
meeting the cutter j will be removed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The method of supporting and drawing a skin over a rod or stick by means of
rolls substantially as herein described.
2. The employment of a rod or stick such as a provided with a flat and
broadened part a to distend the skin and present a flat surface to the cutter
substantially as described and illustrated in the accompanying drawings.
3. The employment of a rod or stick such as a supported by rolls such as b, lit,
c, e, e, substantially as and for the purpose described and illustrated in the
