Figure 9 is a section taken on line 9-9 Figure 8.
Figure 10 is a section taken on line -x of Figure 3.
Figure 11 is an enlarged longitudinal section of one of the cylinders 4, 5.
Referring to the drawings, 1 represents the frame, to which the various parts of
the machine are attached.
2, 3, 4, 5 represent cylinders which are supported on shafts 6, 7, 8, 9. To each
of the cylinders 2 and 3 are attached a series of knives 10, 11. (See Figures 1, 2, 6
and 7).
The brushing device carried by the shaft 8 is an exact duplicate of that carried
by the lower shaft 9, and therefore a description of one will suffice. As seen at
Figure 11, the cylinders 4 are arranged one at each end of the shafts 8 and they
are headed or closed at their inner ends. The shaft passes through their centres
These cylinders
and is keyed to each by means of a key 8* in the usual manner.
are provided at suitable intervals with peripheral slots 21, by means of which and the
bolts 20 that pass through them, the frame 13 is adjustably secured to the cylinders.
Each of these frames consists of two right-angle brackets, (see Figures 3 and 4,)
which have downward projections provided with notches 22, (see Figure 7) and a
bar or strip 13, at opposite ends of which the said brackets are secured, or the said
brackets and bar may of course be formed integral. As shown in Figure 11 these
brackets are arranged radially on the inner ends of the cylinders 4 with their outer
arms, through which the bolts 20 pass, lying upon the peripheries of the cylinders,
while their inner arms lie flat against the inner ends of the cylinders and are held in
place by means of set-scrows 19, resting in the notches 22 and screwing into the
ends of the cylinders. To the bar 13" of each of these brackets are secured metallic
brushes 12, which project approximately radially from the shaft 8, and arranged
bebind each of these brushes is a metallic shield 15, which prevents the brush being
bent back too far, as in so doing it is liable to break. Arranged between the bar 13
and the brush and between the brush and the shield 15 are narrow strips 17, 18, of
pasteboard or other like material, which permit deflection of the brushes to a certain
degree and thereby render them less harsh and less liable to breakage. These brushes

page_text: and the shields 15, as well as the pasteboard strips, are secured together and to the
bars 13 by means of bolts 14, which pass through them and the bars; but the
shields are provided with slots 16, through which the bolts pass in order to permit
radial adjustment of the shields.
It will be seen that when the nuts on the bolts 20 are loosened the frames 13 may
be turned on the set-screws 19, and thus adjust the brushes 12 to the desired angle
of inclination to the casing passing through the machine.
To each of the shifts 6, 7, is suspended a metal bar 23, which is provided with
perforated bosses 23, through which the shaft passes and in which it is capable of
revolving without causing the bar 23 to revolve with it. (See Figures 8 and 9).
To one side of each of these bars 23 is secured by means of set-screws or bolts 24 a
clamp 25, which may by the manipulation of the set-screws 24 be adjusted at various
distances from said bar.
26 is a rubber strip held in the clamp 25 and projecting slightly therefrom, so
that as the knives 10 (or 11) on the cylinder 6 (or 7) go around with the cylinder and
pass the rubber the latter will brush them on their inner sides, and thus remove any
particles that may adhere thereto.
The cylinders 2 are indentical with the cylinders 4 and are similarly arranged on
their shafts, and the cylinders 2, 3, and the parts carried by them are indentical in
every respect. These bars 2, 3, therefore are located on the shaft 6, 7 between the
ends of each of the cylinders 2, 3 and hang downward, as before described, in order to
bring the rubber brush 26 in contact with the sides of the knives.
26 27 are metal strips, which are held in clamps 27 and which extend across
the machine in juxtaposition to and parallel with the cylinders 23 just outside of the
paths of the knives 10 11, so that as the knives revolve with the cylinders and graze
these strips the latter will scrape from them any particles of tallow, &c., which may
adhere to the knives, and thus the outsides of the latter are always kept clean. The
upper clamps 27 are appended to the main frame by hangers 27 while the lower
ones are secured to one of the supporting posts of the journal-box of the shaft 7 by
means of nuts 27°, as shown.
To the rear of the machine is a shaft 28. To the inner end of the shaft 28 is secured
a reel 29 (see figures 1 and 5) on which the casings are wound after they have passed
through the cleaning-cylinders. The arms 30 of the reel are supported at their inner
ends by means of links 31. These links are hinged together and to the arms and
hub of the reel, (see figure 5) so that when it is desired to remove the casings the
inner ends of the arms are closed in towards the centre of the reel and thus permit
the casings to be removed readily.
32. 33. are strips placed across the machine for the purpose of supporting the
casings.
34 is a roller for supporting the casings as they are being wound on the reel.
35 36 are shields, which fit over the top cylinders.
37 is a roller, over which the casings pass on their way to the knives.
38 is a door, through which the tallow is removed after it has been cleaned from
the casings.
39 is the drive belt.
40 is a loose pulley, and 41 is a tight pulley secured to the driving shaft 42.
43 is a short belt, which connects the driving shaft 42 with the shaft 28, to which
the reel 29 is attached.
44 is a belt, which connects the driving shaft with pulleys on the cylinders and
causes them to revolve in the direction shown by the arrows in Figure 11. This
belt also passes over a loose pulley 45 on the shaft 46, that supports the feeding
roller 37.
47 is a drive-chain connecting the drive shaft with the feed-roller shaft; the drive
chain passing over a large sprocket wheel 48 attached to the shaft 46, thus giving a
positive but slow motion to the feed roller.
49 is a rod by which the driving belt can be thrown from the loose pulley to the
tight one, and vice versa.

page_text: 50. 51 are braces which support the inner ends of the shafts on which the cylinders
revolve.
52 is a plate which supports the casings as they leave the feed roller.
It
The operation is as follows: A casing or entrail is passed over the roller 37, supporting
plate 52 and guide 32; thence between the cylinders 2 3 whose knives, as they revole
with the cylinders, cut the tallow from opposite sides of the casing, thence over the
guide 33 thence between the cylinders 4 5, whose fine metallic brushes remove the
finer particles of tallow that may have escaped the knives of the cylinders 2 3.
then passes over the roller 34 and it is attached to the reel 29, whereon it is wound.
As the casing passes through, the knives and brushes remove all the tallow from it,
and the tallow falls into an interior receptacle, from which it may be removed via
the door 38.
I am aware that machines have been invented for removing tallow from small
casings or entrails; but they are not adapted to remove the tallow from middle
casings or large entrails, for which my machine is especially adapted.
The cylinders 2 and 3 are provided with set screws 80, which jam against the
backs of the knives 10 and 11, and by which the knives may be adjusted on the
cylinder.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed as communicated to
me by my Foreign Correspondent I declare that what I claim is :-
