page_text: I, OLIVER DWIGHT WOODRUFF, of Southington in the County of Hartford, and
State of Connecticut United States of America, Mechanic, 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 my invention relates to certain new and useful improvements in Meat
Cutters hereinafter described, reference being had to the accompanying drawings
and the figures and letters of reference marked thereon, similar letters indicating
like parts throughout.
Fig. 1 is a side sectional elevation of my invention. Fig. 2 is a side sectional
elevation of the casing, other parts being removed. Fig. 3 is an end' elevation of
the conical shell forming part of my said invention. Fig. 4 is an end elevation of
the case showing the knives. Fig. 5 is a perspective elevation of the rotatable knives.
In this my invention I employ a metal case A consisting of a cylinder having
formed upon its inside surfaces projecting ribs A¹, and suitable knives A held in
position by suitable screws a. Said case A has an orifice A³ in which the meat
to be cut is inserted. A suitable metal end-piece A having a boss a¹ through
which is the aperture a² forms a bearing for the feed-screw, and is screwed
otherwise fitted into the casing A as shown. The stand A³ is preferably attached to
the case A by a screw a screwed into a boss a¹ said stand A³ being provided with
screw-holes a whereby the machine may be held down, by screws passed through
said screw-holes.
or
The feed-screw B is adapted to be revolved in the casing A by means of any
suitable handle B₁ such as that shown. The pitch of the feed-screw B is varied as
shown, the first two threads being of a more rapid pitch than the remaining threads,
which have cross-threads b. A suitable conical projection 61 projects from the
forward end of the feed-screw B, having formed thereon suitable lugs
carries at its forward end rotatable knives C having lugs c adapted to engage
with the lugs 62 whereby said knives are revolved.
and

page_text: A suitable conical shell D having perforations d, is adapted to fit over the
knives C, and is attached to the casing A by suitably shaped lugs d¹ passed over
lugs a, projecting from the casing A as shown. Said conical shell is firmly. held
in place by a thumb-screw d², which can be unscrewed when it is desired to remove
the shell Ď for the purpose of cleaning.
The operation of my improved meat cutter is as follows:
-
Meat to be cut is placed in the orifice A³ and when the feed-screw is revolved it
is carried forward to the knives C in the conical shell D. The meat being wedged
tightly in the fore part of the feed screw it is cut into pieces by the cross-threads
and the knives A² and the projections A¹. The rotatable knives C which revolve
close to the conical shell D cut the meat into still finer pieces whilst it is forcing its
exit through the perforations d.
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 :-
The combination, in a meat cutter, of the casing A, feed screw B, knives C, and
the conical perforated shell D, constructed and arranged, substantially as and for the
purposes hereinbefore set forth and illustrated in the drawings hereunto annexed.
