We THOMAS GREEN of Smithfield Iron Works Leeds in the County of York,
Engineer and WILLIAM PENROSE GREEN of Smithfield Iron Works Leeds aforesaid,
Engineer do hereby declare the nature of this invention to be as follows:-
This Invention has for its object improvements in meat cutting and sausage cutting
machines.
In these machines we employ rotating cutters having knives with curved blades
and slotted or forked shanks or stems. The axis of the cutter receives collars upon
it; one of these is fixed and the other can slide along a key or feather to admit of
the shanks of the knives being inserted between the collars. The number of knives
may be varied, six however is a convenient number. The collars are recessed to form
sockets to receive the shanks of the knives and they are clamped fast by three bolts
passing through the collars and also through the collars and also through the slotted
or forked shanks. The bolts are symmetrically arranged around the axis and at a
short distance from it, one bolt serving for two knives. Whilst the bolts are slack
the knives can be adjusted in and out from the centre and the knives are securely
held when the nuts on the bolts are screwed up.

Improvements in Meat Cutting and Sausage Cutting Machines.
We, THOMAS GREEN of Smithfield Iron Works, Leeds in the County of York,
Engineer and WILLIAM PENROSE GREEN of Smithfield Iron Works, Leeds aforesaid
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 has for its object improvements in meat cutting and sausage cutting
machines.
In these machines we employ rotating cutters having knives with curved blades
and slotted or forked shanks or stems. The axis of the cutter receives collars upon
it; one of these is fixed and the other can slide along a key or feather to admit of the
shanks of the knives being inserted between the collars. The number of knives may
be varied, six however is a convenient number. The collars are recessed to form
sockets to receive the shanks of the knives and they are clamped fast by three bolts
passing through the collars and also through the slotted or forked shanks. The bolts
are symmetrically arranged around the axis and at a short distance from it one
bolt serving for two knives. Whilst the bolts are slack the knives can be adjusted in
and out from the centre and the knives are securely held when the nuts on the bolts
are screwed up.
In order that our said invention may be most fully understood and readily carried
into effect we will proceed to describe the drawings, hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an end elevation of a rotating cutter for a meat cutting and sausage
cutting machine. This cutter is constructed in accordance with our invention as
above set forth and is suitable for use in machines of the class known as the silent
machines. In these machines the axis is usually horizontal and the knives operate on
the meat whilst the same is contained in a bowl to which rotary motion about a
vertical axis is imparted.
Figure 2 is a side elevation of the boss of the cutter and a portion of the axis; the
knives are removed.
Figure 3 shows separately an elevation of one of the knives.
a is the axis-b is a collar fixed upon this axis and c² ² c³ are other collars free
to move longitudinally on the axis, but fitting it and the key a' therein. d d d are
clamping bolts symmetrically arranged about the axis; the heads of these bolts are
sunk into the fixed collar band their stems project through the moveable collars c¹²²
and at their outer ends receive nuts d' d which when screwed up, clamp all the
collars fast together. e. e. e. are the knives-they have forked or divided stems e e

page_text: and there are recesses in the faces of the collars b. c² c² to receive the forked stems.
The depth of the recesses in the collars is such that the stems themselves become
nipped when the collars are clamped together. Each bolt d, passes through the stems
of two of the knives e, in different planes and so the number of bolts required is only
half that of the knives employed.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is :-
:-
1. Our improvements in meat cutting and sausage cutting machines consisting in
the employment therein of rotating cutters consisting of knives e with forked or
divided shanks clamped between collars b. c¹ c³ etc. one of which is fast upon the axis
and the others clamped to it by screw bolts d, substantially as described.
2. Our improvements in meat cutting and sausage cutting machines consisting in
the employment therein of rotating cutters made substantially as described and
represented by the annexed drawings.
