Germany).
MACHINES FOR SAUSAGE MAKING AND THE LIKE
The machine which forms the subject of this application is of the ordinary shape
consisting of a cylinder, within which works a shaft or barrel with propelling studs
fitted in one or more spiral lines. The studs carry the meat or other substance
against fixed knives, working between them. The upper part of the cylindrical
casing is provided on the top with a hopper to receive the materials and with a
hasp or latch to secure it.
The invention consists firstly and mainly in the manner in which the knives in
such machines are fitted, solidly and yet easy of removal for cleaning, sharpening
or other purposes; and secondly in methods of fastening before the discharge
aperture of the machine, plates with tubes for placing the sausage skins upon.
The accompanying drawing represents three methods of fitting the knives, and
four methods of fastening the sausage tube.
Fig. 1. is a cross section through the lower part of the casing along the line xx
of fig. 2.
Fig. 2. is the front elevation of a machine showing the latch and the delivery
aperture.
Fig. 3. is the top view of the lower casing.
Figs 5, 6, 7, 8, 9, and 10, are details showing the form of the knives and the
modes of their fitting. Figs 11, 12, 13, and 14 are details showing the modes of

page_text: fitting the sausage tube before the delivery aperture. The lower part of the
cylindrical casing is provided along one side with a groove c in a square space
parallel with the axis of the barrel and open at the ends of the machine. This
groove c is formed by the back-side of the casing and a rib a cast on and projecting
from the casting.
The contour may be of any desirable shape. In the drawing a square shape is
represented.
A U-shaped angle-iron of the form fig. 4 is employed to cover the groove c and
the square space in the back of the machine; the part b of the angle-iron thereby
overlapping the rear side of the said square space of which the groove c forms
part.
The parts e and f of the casing are made to enter corresponding notches in the
top plate of the angle-iron which is thus firmly placed in the machine and cannot
be loosened or moved in any direction when the cover of the cylindrical casing is
turned down and latched to the lower part. The angle-iron is provided with
slots g deeply cut into the front and top-plate as shown by figs 4, 5, 6, 7, and 8,
wherein the shanks of the knives are placed. These shanks are provided with
slots k (fig 4) gripping over the rib a, thus holding the knives firmly. The top-
plate of the angle-iron is covered by an extra plate h, rivetted or screwed to the
angle-iron.
In mounting the knives in the angle-iron they are pushed with their shanks
through the slots in the front plate as in fig 4 (section through ED in fig. 5) and
then the whole is set into the square space over rib a whereby the said rib enters
the slots k and holds the knife-blades solidly.
The small end plates ll close up the open ends of the square space. According
to a modification I can dispense with the rib a and slots k and can punch holes in
the shanks of the knives, through which a bolt of corresponding cross section is
pushed from one end of the machine to the other. According to a second modifi-
cation I can apply the slots in the shanks of the knives, as indicated by k¹ in fig 9.
gripping over the lower part of the sheet metal of the slotted angle-iron as shown
in figs. 6 and 7.
Here the knife-shanks cannot be introduced through the front plate.
It must be done through the top plate of the angle-iron, consequently I arrange
the covering plate G removable (not firmly rivetted as h in figs 4 and 5).
In figs. 8 and 10 I have represented two methods of fastening the removable
coverplate G. In fig. 8, the said plate turns round on a screw m.
In order to insert the knives I turn it aside and afterwards turn it over the
angle-iron, whereby a screw n enters a circular slot, and the head of this screw
secures the other end of the plate G. The covering plate fig. 10 is provided with
holes a little larger than the heads of the screws m and n these holes being
elongated sideways to slip under the heads of the screws thus holding the plate.
The shanks of the knives may have besides, holes as indicated above to receive a
bolt or they may have the slots k gripping over a rib similar to the rib a fig. 1.
The second part of these improvements consists in the mode of fastening the
plate with the discharge tube o before the delivery aperture of the machine.
Figs 1 and 2. shew two screws p and q inserted in the machine for the purpose of
holding plates with slots as represented by figs. 11, 12, and 13.
Fig. 3 shows a dovetail groove such as I cut vertically in the body of the
machine right across the delivery aperture. The plate carrying the sausage tube is
pushed in from above. The sides of the groove are a little slanting so that the
plate fits in tightly and firmly. I may also provide the plate with thumbscrews as
shown in fig. 14.

FREDERIC DES Vœux, of Southampton Buildings, in the County of Middlesex
'IMPROVEMENTS IN MINCING MACHINES FOR SAUSAGE MAKING AND THE LIKE
(A communication from abroad by Robert Huebner, of Berlin, in the empire of
Germany.)
The machine which forms the subject of this application is of the ordinary
shape, consisting of a horizontal cylinder, within which works a shaft or barrel
with propelling studs fitted in one or more spiral lines. The studs carry the meat
against fixed knives working between them. The upper part of the cylindrical
casing is provided on the top with a hopper to receive the materials, and with a
hinge on one side and a hasp or latch on the other.
The invention consists firstly and mainly in the manner in which the knives in
such machines are fitted, firmly and yet easily removable for cleaning, sharpening
or other purposes, and secondly in methods of fastening before the delivery
aperture of the machine plates with tubes for placing the sausage skins upon.
The accompanying drawing represents three methods of fitting the knives and
four methods of securing the sausage tube.
Fig. 1 is a cross-section through the lower part of the casing along the line xx
of Fig. 2.
Fig. 2 is a front elevation of a machine shewing the latch and the delivery
aperture.
Fig. 3 is a top view of the lower casing.
Figs. 5. 6. 7. 8. 9. 9 and 10 are details shewing the form of the knives and the
modes of their fitting.
Figs. 11. 12. 13 and 14 are details shewing the modes of fitting the sausage
tube before the delivery aperture.
The lower part of the cylindrical casing is provided on one side with a groove c
in a square space, parallel with the axis of the barrel and open at the ends of the
machine. This groove c is formed by the back of the casing and a rib a cast on
and projecting from the casing. The contour may be of any desirable shape: in the
drawing a square shape is shewn.
A U shaped angle iron of the form shewn in Fig. 4 is employed to cover the
groove c and the square space in the back of the machine, the part b of the angle
iron thereby overlapping the back of the said square space of which the groove o
forms part.
The parts e and f of the casing are made to enter corresponding notches in the
top plate of the angle iron, which is thus firmly placed in the machine and
cannot be loosened or moved in any direction when the cover of the cylindrical
casing is turned down and latched to the lower part.
The angle iron is provided with slots g deeply cut in the front and top plates,
as shewn in Figs. 5. 6. 7 and 8, wherein the shanks of the knives are placed.
These shanks are provided with slots k (Fig. 4) gripping the rib a, thus holding the
knives firmly. The top plate of the angle iron is covered by an extra plate h
riveted or screwed to the angle iron.
In mounting the knives in the angle iron they are pushed with their shanks
through the slots in the front plate, as in Fig. 4, (section through CD in Fig. 5)

page_text: and then the whole is set into the square space over rib a, whereby the said rib
enters the slots k and holds the knife-blades firmly.
The small end plates ee close up the open ends of the square.
By a modification I can dispense with the rib a and slots k and can punch holes
in the shanks of the knives through which a bolt of corresponding cross-section is
pushed from one end of the machine to the other.
By another modification I can form the slots in the shanks of the knives, as
indicated at Fig. 9, gripping the lower part of the sheet metal of the slotted
angle iron, as shewn in Figs. 6 and 7. In this case the shanks cannot be introduced
through the front plate but through the top plate of the angle iron; consequently
I make the covering-plate G removable, not firmly riveted as h Figs. 4 and 5.
Fig. 9 shows a form of knife which allows of the spindle being turned in the
opposite direction, so that the machinery may not be injured.
In Figs. 8 and 10 two methods are shewn of fastening the movable cover-
plate G. In Fig. 8 the said plate turns on a screw m.
In order to insert the knives, I turn the plate G aside and then over the angle
iron, whereby a screw n enters a curved slot and its head secures the other end of
the said plate.
The covering plate (Fig. 10) is provided with holes a little larger than the
heads of the screws m and n, which holes being elongated sideways to slip under
the heads of the screws thus hold the plate. The shanks of the knives may besides
have holes, as described above, to receive a bolt, or they may have slots k gripping
a rib, similar to rib a Fig. 1.
The second part of the improvements consists in a mode of fastening the plate
with the discharge tube o before the delivery aperture of the machine.
Figs. 1 and 2 shew two screws p and q inserted in the machine for the purpose
of holding slotted plates, as shewn in Figs. 11, 12 and 13.
Fig. 3 shews a dovetail groove such as I, cut vertically in the body of the
machine across the delivery aperture. The plate carrying the sausage tube is
pushed in from above. The sides of the groove are slightly bevelled so that the
plate fits in tightly. I may also provide the plate with thumb screws, as shown in
Fig. 14.
Having now described the nature of the said invention as communicated to me
from abroad and the manner of performing the same, I wish it to be understood
that what I believe to be novel and original and desire to claim on behalf of the
said Robert Huebner is
Firstly. In mincing machines with stud barrels the application of an angle iron b
provided with slots for holding the shanks of the knives, and cover h riveted
thereto, which angle iron is placed over the groove c in the upper or lower part of
the casing, overlapping the back of the said groove and dovetailed over the sides
ef, substantially as described and shewn in Figs. 1. 3. 4 and 5 of the accompanying
drawings.
Secondly. The application of the cover G to the said angle iron to secure the
knives and to close the slots tightly, so that pieces of fat and like matter cannot
enter, substantially as described and shewn in Figs. 1. 3. 6. 7. 8. 9 and 10 of the
accompanying drawings.
Thirdly. The application of a rib a cast on the upper or lower casing in the
groove con which rib the shanks of the knives put into the angle iron b may grip
and be held firmly (or a bolt passing through the shanks of the knives), subtantially
as described and shewn in Figs. 1. 3. 4 and 5 of the accompanying drawings.
Fourthly. The method of fixing and loosening the sausage-tube o before the
delivery aperture, consisting of a plater provided with slots and screws (p and q),
substantially as described and shewn in Figs. 1. 2. 3. 11. 12 and 13 of the
accompanying drawings.
Fifthly. The method of fixing and loosening the sausage tube o before the

page_text: delivery aperture, consisting of two bevelled ribs cast on or fixed to the machine
provided with dovetail grooves in combination with a plate carrying the sausage-
tube fitting the said dovetail groove and pushed in from above.
In witness whereof, I, the said Frederic Des Voeux, have hereunto set my
hand and seal this first day of September 1882.
