Improvements in Machines for Mincing, or Simultaneously Mincing
and Filling into Skins or other Receptacles, Meat and other like
Plastic or Yielding Substances.
1 THOMAS WILLIAMS the Younger of 45 Myddleton Square in the County of
Middlesex, Engineer, 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 improvements in the class of mincing machines, described
in the specification to my patent No. 4771 A.D. 1884.
A machine constructed according to my invention may also be employed for
simultaneously mincing and filling the meat into skins, or other receptacles, if
desired.
The object of my invention is to provide a machine which will mince and deliver
the meat more quickly, without reducing it to a pulp, leave little or no waste in the
machine, and be simpler and cheaper to construct.
To attain these objects, I bring the extremity of the propeller or forcing screw
to within a short distance of the delivery end of the casing, and in order to enable
me to give as many cuts as heretofore to the meat, for each revolution of the handle
or driving shaft, and yet arrange and dispose all the cutting devices within the small
space left between the extremity of said propeller, and the end of the casing, I sub-
stitute for the revolving claws, or single or double bladed knives, ordinarily employed
in machines of this class, what are known as "star" knives, or cutters, each knife or
cutter having a number of blades (say four, five, or more) rotating in the same plane.
I also prefer to cast the casing in one piece, and provide it with the well-known
internal spiral grooves.
When it is desired to use the machine as a filler also, the supplementary propeller
and filling nozzle described in the specification to my patent No. 7125 A.D. 1886
may be employed.
I will now proceed to describe my invention more particularly, having reference
to the accompanying drawings, in which:
:-
Figure 1 is a side elevation of the machine, (here shewn as adapted for filling also,)
the casing and filling nozzle being shewn in section.
Figure 2 is a view of the delivery end thereof, with the filling nozzle removed.
Figures 3 and 4 are detached views of the revolving "star" cutters, and stationary
knives employed.
A is the casing of the machine, provided with the usual hopper B, and the well-
known internal spiral grooves, and preferably cast in one piece. C is the propeller
or forcing screw, upon the axis D of which are mounted, so as to turn therewith, the

"
star" knives or cutters E E, (here shewn as having six blades cach,)
FF are the stationary knives, also threaded upon the spindle D, which turns freely
within apertures formed in their centres, the extremities of said stationary knives
resting in the recesses or slots G, cast in the casing. H is a supplementary propeller,
of the kind described in the specification to my patent No. 7125 A.D. 1886, screwed
on the end of the axis D, threaded at its extremity for that purpose, which propeller,
in conjunction with the filling nozzle I, serves to fill the minced meat into skins, or
other receptacles, when required. When it is desired to use the machine as a mincer
alone, the supplementary propeller H, and filling nozzle I, may be dispensed with,
and a nut on the threaded extremity of the axis I substituted therefor.
The simultaneous adjustment of the cutting parts towards or from one another, is
effected by screwing up or unscrewing the supplementary propeller, or nut, as the
case may be, whilst all the working parts may be withdrawn together from the front
end of the casing, for cleaning purposes, on removing the driving handle.
K is a small hole, formed in the supplementary propeller, for the insertion of a
wrench by which it may be conveniently screwed up or unscrewed.
It will be readily seen, that in a machine of this construction, wherein the knives
or cutting devices are confined to a small space at the delivery end of the casing, and
the propeller or feed screw is continued up to such knives, and consequently to within
a short distance, say half an inch of so, of the delivery end of the casing, that the
meat will be expelled much faster, and less waste remain in the machine, than in
machines of this class as heretofore constructed, whilst the employment of the rotating
star" cutters, having each several blades revolving in one plane, in lieu of the old
pattern knives or claws, used in machines of this class, enables me to give the same
number of cuts at each revolution of the driving shaft or handle, as heretofore, and at
the same time take up very little space.
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. A mincing machine of the class described in which the cutting or mincing of
the meat is effected solely by means of "star" cutters or knives, revolving in cutting
contact with stationary knives, and threaded upon, and turning with, the axis or
spindle of a propeller or forcing screw, substantially as specified and illustrated.
2. The combination with a casing having internal spiral grooves, of a propeller or
forcing screw C, "star" cutters E, stationary knives F, supplementary propeller H,
and filling nozzle I, all arranged and disposed as and for the purpose specified and
illustrated.
3. In a mincing machine of the class referred to, the combination with a casing
having internal spiral grooves, of a propeller C, one extremity of which extends nearly
to the delivery end of the casing, and revolving "star" cutters or knives E, acting in
conjunction with stationary knives F, and threaded upon the axis or spindle of the
propeller, substantially as and for the purpose specified and illustrated.
