I, FREDERICK WILLIAM FOLLOWS, of Floxme Street, Gorton, in the County
of Lancaster, Agricultural Engineer, do hereby declare the nature of this invention
to be as follows
-
This invention relates to that class of mincing machine in which the meat is
cut or reduced to the desired degree of fineness by a number of blades acting as a
propeller and working against a number of fixed or stationary blades.
Hitherto such cutting or mincing propellers have been constructed by placing or
atringing a number of separate blades upon a shaft or spindle at the desired
distance apart and at the proper inclination to each other to form a propeller I find
however that the cost of production will be reduced and more efficient mincer
may be produced by first casting a propeller or screw of the desired shape aud
pitch and then cutting out of it the desired number of blades.
My invention therefore consists essentially in constructing the rotating or moving
part of the machine by casting it in the form of the propeller or screw and then
forming the cutting blades thereon by cutting a series of slots across the same by
a saw or milling cutter of suitable construction.
In enrrying out the invention 1 form the casing of the machine and the
stationary blades in any ordinary or convenient manner and to this I insert a cutting
propeller made as follows:-I cast a screw of the desired shape with one or two
theads of a coarse or wide pitch and in the threads so formed I cut by means of a
circula or other saw or by a milling cutter or other suitable tool a number of
tiansverse slots or lits corresponding with the number of fixed cutters employed.
By the cutting of these slots a number of cutters on blades ato formed which act
in conjunction with fixed blades and shear or mince the meat to the desired
condition of fineness.
The casing the fixed blades and the cast iron propeller or cutters are all
preferably tinned though they may be galvanised enamelled or otherwise conted
to prevent rust or corrosion.

Improvements in Mincing Machines.
1, FREDERICK WILLIAM FOLLOWS, of Froxmer Street, Gorton, in the County
of Lancaster, Agricultural 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 that class of mincing machine in which the meat is cut
or reduced to the desued degree of fineness by a number of blades acting as a
propeller and working against a number of fixed or stationary blades.

or stringing a number of separate blades upon a shaft or spindle at the desired

find however that the cost of production will be reduced and a more efficient mince
may be produced by first casting a propeller or serew of the desired shape and
pitch and then cutting out of it the desired number of blades.
My invention therefore consists essentially in constructing the rotating or
moving part of the machine by casting it in the form of the propeller or screw
and then forming the cutting blades thereon by cutting a series of slots across the
same by a saw or milling cutter of suitable construction.
It will be fully described with reference to the accompanying drawings in which
the improved form of forcing screw and cutter is shown removed from the
machine.

I form the casing and the stationary blades of the machine in the usual or any
convenient manner such for instance as described in the Specification of a subsequent
application for Letters Patent made by me No. 16,078 of 1895.
The cutting propeller A 1 make as follows:- cast a screw of the desired shape
with one, two or more threads of a wide pitch and in the threads so formed, I
cut any number of transverse slots or slits a that may be required preferably
corresponding with the number of fixed cutters employed in the machine.
The slots a are cut by a circular or other saw or by a milling cutter or other
suitable tool caused to rotate whilst the screw is either held stationary or caused to
rotate.
By thus cutting the slots a in the solid thread of the screw a number of cutters
or blades a' are formed with sharp cutting or shearing edges which not in conjunc
tion with the fixed blades and shear or mince the meat to the desired degree of
fineness.
The casing, the fixed blades and propeller A and cutters a' are all preferably
tinned though they may be galvanised, enamelled or otherwise coated to prevent
rust or corrosion.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim 15 :--
A forcing and cutting screw or propeller for mincing machines constructed of a
number of blades such as a' formed by cutting slots a in the solid thread of the
screw by means of a circular saw, milling cutter or other suitable tool substantially
as described and shown.
