the Skins for Black
Puddings and Mixing the Ingredients thereof.
I, ROBERT DAVIDSON WADDELL, Sausage Manufacturer, Mount Street, West,
Glasgow in the County of Lanark, North Britain, 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 which relates to a new or improved machine for filling the skins
for black puddings and mixing the ingredients thereof has for its object to facili-
tate the manufacture of such puddings and to improve the quality of the article
when manufactured.
In order that my Invention may be properly understood and readily carried into
effect I will now proceed to describe the drawings hereunto annexed.
Figure 1 is in part a longitudinal section, and in part a side elevation of a machine
constructed according to this Invention. Figure 2, is a transverse section of the
same taken on the line A B, Figure 1, and Figure 3 a plan.
The machine consists of two main portions one being that part of the apparatus
whereby the mixing of the ingredients required for the manufacture of black
puddings is effected, and the other constituting the mechanism for charging the
material into the skin or skins of such puddings.
The mixing portion of the machine consists of the cylindrical drum or mixer C,
into which the material is charged through the hopper D, and mixed by the rotation
of the rectangular frame E, on the horizontal shaft F, the said shaft F, being
rotated from the belt pulleys G, and H, on the main or driving shaft I by spur wheel
gearing, which shall be hereinafter described.
The rectangular frame E, (when revolving) besides mixing the material, also
cleans the internal periphery of the drum or mixer C, and thus prevents the blood
from adhering thereto.
It is to be understood that the mixer C, may be placed in several different positions
to that shewn on the annexed drawings without departing from the principle of the
Invention, and that the construction of the mixing frame or blades may be altered,

page_text: that is, the axis of the mixer C, may be in the some plane, but at right angles to the
position shown and the mixing blades may consist of two bars projecting from a boss
keyed or otherwise secured to the shaft F, the said bars having an arm set obliquely
at the end of each, so arranged as to scrape the internal periphery of the mixer C,
and direct the material towards the exit J. Or if desired the mixer or drum C, may
be situated with the shaft F, vertical, the bottom of the shaft being carried on a
footstep secured to the interior of the mixer C, and bridging the exit J, or the said
shaft F, may be hung from the top of the mixer C. As the upper end of the
vertical shaft F, will pass out centrally through the top of the mixer C, the hopper D
will be placed on the top, but near the periphery of the same. When the position
of the mixer is adopted, the mixing blades can be constructed similar to those of a
pug mill and revolve in a horizontal plane, the blades being twisted to drive the
material out at the exit J. To keep up the necessary heat required to prevent the
blood from adhering to the sides of the mixer and retarding the operation, the said
mixer may be jacketed, the space between the mixer and jacket being filled with steam
or hot water.
The second main portion of the machine or that constituting the mechanism for
charging the material into the skin or skins of black puddings consists of a
novel single acting force pump with its driving and reversing gear.
The plunger K of the said pump is represented in Figure 1, at mid stroke with
the clack or flap valve L open that it may be more readily seen, the machine being
at rest, the driving belt being on the loose pulley M, and the reversing gear
in its corresponding postion. Assuming that the driving belt has been directed, by
means of the ordinary belt shifting bar N, and prongs O, from the loose pulley M,
to the pulley G, which is loose on the driving shaft I, but on whose hub there is
keyed the spur wheel P, which gears with a wheel Q, on an intermediate shaft R, on
whose back end a spur wheel S, is situated and geared with a suitable spur wheel T,
on the plain cylindrical end of the screw shaft U, as this wheel T revolves, the screw
shaft U, rotates with it, causing the cross-head V, which is similarly screw threaded,
and slides on the guide rod W, to travel rectilinearly, and drive the hollow plunger K,
connected to it by the rods X, towards the front end of the cylinder Z, forcing any
material that might be at that end of the cylinder into the skins, previously slipped
over the nozzle Y, to receive it. The nozzle Y, is fitted to the nose of the cylinder
with an ordinary hose coupling or bayonet joint arrangement to render it capable of
being placed in position upon the machine or removed therefrom with great
facility.
Whilst the plunger K is being driven towards the front of the cylinder Z, and
forcing the material contained therein into the skins (the clack or flap valve I, being
of necessity shut) the back end of the cylinder Z, and hollow plunger K, are being
filled from the contents of the mixer C, the head of material within the same being
sufficient for that purpose. On the back stroke of the plunger the greater part of the
material contained within the hollow plunger K, and cylinder Z, passes through the
clack valve L, towards the front end of the cylinder Z, to be expelled on the return
stroke of the plunger K, into the skin on the nozzle Y. The amount discharged at
each forward stroke is proportional to the internal diameter of the cylinder and the
stroke of the pump. Instead of the plunger K, a piston or bucket with clack valve
may be used, the length of the cylinder Z, being altered to suit.
The reciprocating motion of the plunger is effected automatically through the
intervention of the reversing gear, and is as follows. Assuming the driving belt to be
on the forward motion pulley G (the train of gearing wheels for same having been
already described) and the plunger K, nearing the end of its stroke, the crosshead V,
strikes against the front upstanding end of the tappet link "a," carrying the said
link "a
which is suspended at its extremities from the guide rods W, forward with
it, thereby moving the weighted lever "b," on the fulcrum "c" through the interven-
tion of the connecting rod "d," until the weighted lever is carried so far out of the
vertical, that it falls forward, and in doing so changes the fulcrum, about which it
turns, from c to e, when immediately the belt shifting bar N,
and prongs O are driven

page_text: backwards, and the driving belt put on the backward motion pulley H, which is
secured to the main or driving shaft I, on whose back end is keyed the spur wheelf,
geared to the beforementioned wheel T, on the screw threaded shaft U, which now
revolves in opposite direction to that first described and consequently carries the
crosshead backwards until it strikes against the back upstanding end of the tappet
link "a," when the weighted lever falls backwards and lifts the belt from pulley H to
pulley G. The backward stroke is performed much quicker than the forward stroke,
the gearing being arranged to suit.
As the mixer c, is rotated from a spur wheel g, on the screw threaded shaft U, and
geared with the wheel i, through the intermediate wheel h, the said mixer is rotated
alternately in opposite directions corresponding in duration with the forward and
backward motion of the plunger K. If it be desired to stop the continuous working
of the mixer and make it intermittent, the wheel h, may be provided with a clutch
to put the wheel h in gear or out of gear at will.
The machine is carried on three standards "k," the pump K and mixer C being
mounted on two of them, the back one of which in conjunction with the third support
carries the driving and reversing gear.
The machine can also be driven by hand power if desired, a suitable hand wheel
being fixed to the back end of the screw threaded shaft U.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I
claim is :
First. The combination of the several parts constituting the new or improved
machine for filling the skins for black puddings and mixing the ingredients thereof
substantially as herein before described with reference to the annexed drawings.
Second. In a machino for filling the skins for black puddings and mixing the
ingredients thereof, the combination of parts constituting the new or improved
mechanism for mixing the ingredients of black puddings, the said mechanism being
arranged according to any of the methods, substantially as herein before described with
reference to the annexed drawings.
Third. In a machine for filling the skins for black puddings and mixing the
ingredients thereof the combination of parts constituting the improved pump for
filling the skins for black puddings, substantially as and for the purpose specified with
reference to the annexed drawings.
Fourth. The combination of the parts constituting the driving and reversing gear
substantially as set forth with reference to the annexed drawings.
