Improvements in or Additions to Machines for Mincing Meat
and other Substances.
I FREDERICK JOHN GARDNER trading as John Gardner and Son of Smithfield
Works No. 11 Bradford Street Birmingham in the County of Warwick Machinist
do hereby declare the nature of this Invention to be as follows:-
My invention consists of the improvements in or additions to machines for mincing
meat and other substances hereinafter described whereby an independent steam engine
for driving the mincing machine is dispensed with and the mincing machine is driven
by a steam engine which is combined with and forms an integral part of the
machine.
I prefer to apply my invention to meat mincing machines of the construction
described represented and claimed in the specification of Letters Patent granted to me
on the 3rd day of September 1881 No. 3841 but my invention may be applied to meat
mincing machines of other kinds. In a combined mincing machine and steam engine
made according to my invention I so construct and arrange the parts that the steam
engine by which the machine is driven is carried by one of the sides or standards of
the machine that is by the side or standard at which the pulley end of the knife
spindle is situated.
Portions of the steam engine are cast on the inner face of the said side or standard
of the machine and form one piece therewith. The parts cast on the said side consist
of the guides between which the cross head works and the steam cylinder cover or
end together with the pedestal for carrying the brasses or bearings in which one end
of the crank shaft of the engine works the opposite end of the crank shaft working
in brasses or bearings on the underside of the machine plate supported by the sides or
standards. The crank rod by which the crank shaft is worked and the piston rod of
the piston working in the steam cylinder are connected to the cross head sliding in
the guides cast on the side or standard in the ordinary way.
The crank shaft of the steam engine constitutes the driving shaft of the mincing
machine the knife spindle of the mincing machine being worked from the said crank
shaft by gearing of any required kind.

Improvements in or Additions to Machines for Mincing Meat
and other Substances.
I FREDERICK JOHN GARDNER trading as John Gardner and Son of Smithfield
Works, No. 11 Bradford Street, Birmingham in the County of Warwick, Machinist
do hereby declare the nature of my Invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
My invention consists of the improvements in or additions to machines for mincing
meat and other substances herein after described, whereby an independent steam
engine for driving the mincing machine is dispensed with and the mincing machine
is driven by a steam engine which is combined with and forms an integral part of the
machine.
I prefer to apply my invention to meat mincing machines of the construction
described represented and claimed in the specification of Letters Patent granted to
me on the 3rd day of September 1881 No. 3841 but my invention may be applied to
meat mincing machines of other kinds. In a combined mincing machine and steam
engine made according to my invention I so construct and arrange the parts that the
steam engine by which the machine is driven is carried by one of the sides or
standards of the machine that is, by the side or standard at which the pulley end of
the knife spindle is situated.
Portions of the steam engine are cast on the inner face of the said side or standard
of the machine and form one piece therewith. The parts cast on the said side consist
of the guides between which the cross head works and the steam cylinder cover or
end together with the pedestal for carrying the brasses or bearings in which one end
of the crank shaft of the engine works, the opposite end of the crank shaft working in
brasses or bearings on the underside of the machine plate supported by the sides or
standards.
The crank rod by which the crank shaft is worked and the piston rod of the piston
working in the steam cylinder are connected to the cross head sliding in the guides
cast on the slide or standard in the ordinary way.
The crank shaft of the steam engine constitutes the driving shaft of the mincing
machine the knife spindle of the mincing machine being worked from the said crank
shaft by gearing of any required kind.
I will now proceed to describe with reference to the accompanying Drawings the
manner in which my invention is to be performed.
Figure 1 represents in front elevation a combined mincing machine and steam
engine for driving it constructed according to my invention and Figure 2 is a vertical
section of a portion of one of the sides or standards of the machine taken on the
line a, a Figure 1, the said section exhibiting the guides cast on the side or standard
and the cylinder end plate or cover; Figure 3 is a plan of the machine the rotating
pan and knife and portion of the knife spindle being omitted.

Drawings.
is the back standard or side of the machine supporting the steam cylinder and
other parts of the steam engine by which the mincing machine is driven and c is the
front standard or side of the machine. On the inner face of the said side or standard b,
the guides d, d are cast together with the cover or end plate e of the steam engine
cylinder the said parts d, d and e forming one piece with the said side or standard b.
The shape of the guides d d on the inner face of the side or standard is seen in
Figure 2. To the cover or end plate e forming one piece with the side or standard b
the steam cylinder is bolted, the said cylinder carrying the steam chest g (see
Figure 3) is the steam pipe passing to the steam cylinder chesty the passage of
steam through the said pipe being regulated and cut off by the action of the lever i
operating upon a throttle valve in the said pipe as usual. The exhaust pipe in the
steam chest is not represented: k is the cross head of the piston rod the slippers of
which cross head work between the guides d, d on the side or standard b..

C
The mincing machine is driven from the steam engine in the following manner:
m is a horizontal crank shaft worked by the crank rod n connected to the cross head k.
The crank shaft m constitutes the driving shaft of the machine and is supported in the
pedestals and brasses at p. 1. The pedestal at p is situated on the inner face of the
side or standard of the machine and is cast in one piece with the said side and
the pedestal at is cast in one piece with the other side or standard c of the machine.
On the crank shaft m is the eccentric (see Figure 3) which works the eccentric
rod for operating the slide valve in the steam chest y : s is the rotating pan of the
mincing machine supported on the vertical shaft s² and is the spindle carrying the
knife the said knife spindle being supported in bearings from the machine plate ;
3 is a fly wheel on the knife spindle t. The pan spindle 2 is worked from the
crank or driving shaft m by the worm or tangent wheel a on the said shaft m gearing
with the large toothed wheel y on the bottom of the pan spindle s² and the knife
spindle is driven by the driving band m² working over the driving pulley on the
knife spindle t and over the large driving pulley m³ on the crank shaft m.
Having now particularly described and ascertained the nature of my invention
and the manner in which the same is to be performed I declare that I claim as
my invention of "Improvements in or additions to machines for mincing meat and
other substances"
First The combination with a mincing machine of a steam engine for driving it
the said steam engine forming an integral part of the machine, the end plate or cover
of the cylinder and the guides for the cross head of the steam engine being cast in
one piece with that side or standard of the machine at which the pulley end of the
knife spindle is situated, the several parts being constructed and arranged substantially
as herein before described and illustrated in the accompanying Drawings.
Secondly The arrangement or combination of the parts herein before described and
illustrated in the accompanying Drawings for driving the knife spindle and pan spindle
of the mincing machine from the crank shaft of the steam engine, which crank shaft
constitutes the driving shaft of the mincing machine.
