page_text: I. EDWARD FURNESS, of The Bone Machine Works, Dale Street, Accrington,
in the County of Lancaster, Maker of Bone Cutters and Shell Grinders, do hereby
declare the nature of this invention to be as follows:-
My said invention relates to bone cutting machines for green bones used for
the preparation of poultry food and the like. The object of my invention is to
devise a machine which shall be certain in its action, easily managed and not
likely to get out of repair.
In constructing a machine in accordance with my invention I employ the
usual disc provided with a series of adjustable knives and apertures for the
emission of the bones when cut. I mount this disc loosely upon a horizontal
spindle which is secured in a suitable framework or standard. The periphery of
the disc is formed with spur teeth which mesh with the teeth of a pinion mounted
to revolve loosely upon a spindle secured to the frame of the machine. Secured
to or forming part of the pinion is a hand wheel or lever of convenient size re-
volved by a handle so that motion can be imparted to the cutting disc through
the gearing.
The framework of the machine carries a horizontal cylinder or receptacle for
the bones one end of the cylinder being disposed against the face of the cutting
disc. Upon the horizontal spindle is mounted a presser with a disc face adapted
to enter the hollow cylinder provided for the bones. The horizontal spindle is
formed for a portion of its length with a coarsely pitched screw thread and a
hand wheel is mounted upon the screwed portion of the spindle. By revolving
the hand wheel the attendant can thrust forward the presser within the cylinder
at any desired speed.
To operate the machine the presser is withdrawn from the interior of the
cylinder which is then charged with green bones.
The disc of the presser is then brought to bear against the bones by means of
the hand wheel on the spindle. The cutting disc is revolved and the attendant
gradually feeds forward the presser as the bones are cut up until the contents
of the cylinder are exhausted or practically so.
An important advantage of my invention is that the feed of the presser can
be regulated to a nicety as the cutting proceeds, so that the cylinder is not likely
to become choked by excessive feed. Further the screw upon which the hand
wheel is mounted being of coarse pitch it is strong and not liable to strip owing
to the back pressure against the presser disc.

page_text: I, EDWARD FURNESS, of The Bone Machine Works, Dale Street, Accrington,
in the County of Lancaster, Maker of Bone Cutters and Shell Grinders, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement and accompanying drawings:
My said invention relates to bone cutting machines for green bones used for
the preparation of poultry food and the like. The object of my invention is to
devise a machine which shall be certain in its action, easily managed and not
likely to get out of repair..
The accompanying sheet of drawings to which I will refer clearly illustrates
my improved machine.
Fig. 1 is a side elevation of the machine.
Fig. 2 is a plan thereof partly in section.
Fig. 3 an end view.
Figs. 4 to 7 are detail views.
In constructing a machine in accordance with my invention I employ the usual
disc a provided with a series of adjustable knives or cutters band apertures c
for the emission of the bones when cut. The disc a is shown separately in front
elevation in Fig. 6, whilst Fig. 7 shows in section a portion of the disc a showing
more clearly the knife b secured to the disc by means of a set screw b¹ passing
through a slot in the knife, and also the adjusting screw b. I do not claim anything
novel however in the construction of the disc a and cutters b. I mount the disc a
loosely upon a spindle d secured to a cylinder e carried by standards f f bolted
together by bolts 2. The standards f are hollowed out for the reception of
the cylinder e, and the cylinder is provided with projecting ledges el e¹ which
sit upon and are bolted to snugs fl carried by the brackets f (see Fig. 2). The
periphery of the disc a is formed with spur teeth which mesh with the teeth of
a pinion g mounted to revolve loosely upon a spindle h secured to the frame of
the machine. Secured to or forming part of the pinion is a hand wheel i, or
lever of convenient size, revolved by a handle so that motion can be imparted
to the cutting disc through the gearing.
The horizontal cylinder e or receptacle for the bones is open at each end and
is disposed at one end against the face of the cutting disc. The interior of the
horizontal cylinder e is divided by means of a web e² shown more clearly in
Fig. 2 and in the separate front view of the cylinder e Fig. 4.
The web e is formed with a boss e into which is screwed or secured the
spindle d. Upon a horizontal spindle k is mounted a presser j with a disc
face adapted to enter the hollow cylinder e provided for the bones. The face of
the presser j is formed with a central hole j and slot 2 as shown in the detached
front view Fig. 5. When thrust inside the cylinder e the central hole ¹ fits
loosely around the boss 3 and the slot permits the passage of the web e so
that the presser jis thus guided and supported by the boss e³ and web e² of
the cylinder e.
The horizontal spindle k is formed with a coarsely pitched screw thread and is
also screwed or otherwise secured to the boss of the horizontal cylinder e
and a hand wheel is mounted upon the screwed portion of the spindle. By
revolving the hand wheel the attendant can thrust forward the presser ; within
the cylinder e at any desired speed.
To operate the machine the presser is withdrawn from the interior of the

page_text: cylinder e as shown in the drawings and the cylinder is then charged with green
bones.
The disc of the presser j is then brought to bear against the bones by means of
the hand wheel on the spindle k. The cutting disc a is revolved and the
attendant gradually feeds forward the presser j as the bones are cut up until the
contents of the cylinder e are exhausted or practically so.
An important advantage of my invention is that the feed of the presser can
be regulated to a nicety as the cutting proceeds, so that the cylinder is not likely
to become choked by excessive feed. Further the screw upon which the hand
wheel is mounted being of coarse pitch it is strong and not liable to strip owing
to the back pressure against the presser disc.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
-
The improved apparatus for cutting green bones consisting of a horizontal
cylinder carrying a cutting disc actuated by gearing, and provided with a hori-
zontal coarsely pitched screw threaded spindle upon which is arranged a presser
actuated manually by means of a hand wheel the whole arranged and acting in
the manner and substantially as described and illustrated.
