Improvements in Machinery for the Manufacture of
Black Puddings.
We, SILAS DAWSON of 55 Bury New Road, Prestwich, near Manchester, Pork
Butcher, and JAMES DOUGLAS HARTLEY of 3 East Parade, Keighley Road,
Colne, Builder, do hereby declare the nature of our said 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 refers to a simple and compact arrangement of mechanism
for mixing together the necessary ingredients, blood, groats, etc., and for
introducing the same into the casings or skins in the manufacture of black
puddings.
And in order that our said invention shall be the more readily understood and
carried into practical effect we have hereunto annexel a sheet of drawings and will
now proceed to describe the same with the assistance of the various figures and
letters of reference marked thereon:-
Fig. 1. is a front view partly in section. Fig. 2 a side elevation, and Figs. 3, 4,
and 5 detail views of our improved machine.
(a) is a trough or hopper through which a shaft (c) revolves, carrying a
mixer (d) for thoroughly mixing together the usual ingredients used in the
manufacture of black puddings, and which are to be introduced into the trough
or hopper (a) by the removal of the cover (b). The shaft (c) passes out through
a gland (f) and has a spur wheel (g) secured upon its end. This spur wheel (g)
gears with another spur wheel (h) keyed upon a shaft (') running in brackets
attached to the main frame (2) of the machine, and upon the end of this shaft (¹)
a winch handle (2) is secured, by turning which, the wheel (g) and the mixer (d)
can be effectually rotated. The ingredients in the hopper (a) are thereby
effectually mixed and subsequently fall into the pressing cylinder (j), and by means
of a ram or piston operated from the crank shaft (') are discharged through the
funnel (k) into the skins.
We find that it is a matter of great practical importance that the mixer (d)
should be capable of rotation without necessarily putting into operation the
pressing movement as the materials are very liable to settle at the bottom of the
hopper (a), and it is often times desirable to operate the mixer (d) a few turns
without pressing forward any of the material into the skin. Our invention relates
more particularly to the mechanism for performing this, and in carrying it out
We arrange that the wheel (h) may be moved out of gear with the wheel (7) which
drives the pressing ram. One method of carrying out this is to make the wheel (h)
twice the width of the wheel (1) and to allow the shaft (h) to slide endwise in its
bearings in the main frame, so that whilst (h) gears with () it may miss (1). For
this purpose the wheel (7) is set out of line with (g), and a latch (m), pivoted
at (n) to the main frame (a), is arranged to drop on either side of a collar (o) on
the shaft (¹).
In operating this our improved machine we first use the mixer (d) by pushing
the shaft (') as far forward as it will go, drop the latch (m) on the rear side of
the collar (o), and the wheel (h) thus drives the mixer ouly, and when the mixing
process has been sufficiently performed, we lift the catch (m) and draw forward
the shaft (1), drop the said latch on the far side of the collar (o) and so put in gear
the three wheels (h), (9) and (1) when the pressing process goes on simultaneously
with the mixing.

page_text: It is very desirable that whenever the machine stops the ram within the pressing
cylinder (J) should cover the opening in the cylinder, and to effect this we weight
one side of the wheel (1) at (p) so that when wheel (4) retires out of gear with
it, the preponderance at (p) will traverse the piston or plunger to the desired
position.
Having thus particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim and desire to secure by Letters Patent is :-
1st. The combination and arrangement of mechanism for the manufacture of
black puddings substantially as hereinbefore described and illustrated on the
accompanying drawing.
2nd. The wheel (1) arranged to gear constantly with the wheel (g), and
permissably with the wheel (7) substantially as and for the purposes set forth.
Dated this 12th day of September 1895.
