A designates the standard, provided with any suitable base or foot 11 for securing
it to a bench, table, or other support. Its upper end is provided with a clamp 12,
made integral with said standard and provided with a clamping device 13 in the
form of a screw. This clamp is of a curved form in side view and is provided at
its inner edge with opposing notches or recesses 14.
I make the case in two segmental parts, the front part B. having rabbeted ribs
or longitudinal ledges 15, adapted to be received within the recesses 14 of the
clamp 12, and into the rabbets of which the rear part C of case fits, as shown.
The hopper 16 is formed partly in each of the parts B. C. The inner side of the
case near the hopper is provided with what I may term "long" and "short"
feeding-ribs 17 and 18, extending along the length of the case, preferably in a
somewhat spiral form, in accordance with the long and short ribs of my United
States Patent, No. 369,744, dated September 13, 1887. At the hopper end of the
case there is a plain band 19 on each part, that is turned out or milled smooth and
flush with the tops of said ribs. Toward the opposite or delivery end of the case
there is a series of cutting elevations 20, with spaces between the elevations and
spaces extending directly around the case circumferentially without inclining
longitudinally, although said series of cutting-elevations are arranged in spiral
DQ37

form. The tops and sides of these cutting-elevations and the bottoms of the spaces
between them are also milled or turned smooth and true concentrically. The inner
face of the part B is the same as that of the part C.
G designates the rotary part of the cutter, which I term for convenience, the
screw," although it is in fact a combined screw and cutter. At one end it is
provided with any ordinary crank H or other means for driving it, and also with
a short cylindrical portion 21, that takes its bearings in the plain band 19 of the
case. The screw-web 22 extends along from the short cylindrical portion 21 in
an ordinary form, with the top or greatest projection of the web of a height that
will bear on the feeding-ribs. Toward the delivery end of the screw G there are
other webs 23, divided into a series of cutting-elevations by circumferential
grooves 24, the surface of which cutting-elevations take their bearing in and are
fitted to the cutting-elevations of the case, the elevations on one part entering and
filling the circumferential groove or spaces between said elevations on the other
part.
The parts are not only turned or milled to fit each other, but they should, when
fitted be ground to insure a close fit between the bearing parts on the screw and
case. The ledges on the part B rest in the notches of the clamp 12, and the
clamping device 13 not only holds the case to the standard, but binds the two parts
of the case firmly on the screw, a slight space being left between the confronting
edges of the two parts of the case, as shown in Fig. 2, to always insure a proper
bearing of the screw and case instead of permitting the two parts of the case to
bear against each other. The screw not only takes its axial bearing in the case,
but the circumferential grooves therein and the cutting-elevations on the case which
enter said grooves, serve to hold the screw and two parts of the case against moving
one upon the other in a longitudinal direction. The action of the screw in
connection with the long and short ribs of the case is the same as in my aforesaid
Patent. The cutting-elevations on the screw and case act to cut the meat rapidly
and securely, and inasmuch as their cutting-faces are in actual contact nothing can
pass by them without being cut. As the parts all bear and can be taken up as
fast as they wear, the machine is self-sharpening and very durable.
In Figs. 6, 7, and 8 I have shown the rear part D of the case as having a stem 25.
for being secured to a standard having a socket, as in my United States Patent,
No. 422,644, dated March 4, 1890. I have also shown the ledges 15, before
described, as on said rear part D and the other part E fitted in the rabbet of said
ledges, while said two parts are held together by the same form of clamp 12, and
screw as before described, although said clamp is not made a part of the standard.
This form of case, clamp, and a standard may be applied to a machine having a
screw and case with inner faces of the form first described.
The inner faces of the parts DE have long and short ribs 177 and 178; but
the particular form of feeding-ribs is not necessary so long as the top of web 22
is fitted to and bears upon the top of said ribs. Neither is the form of the cutting-
elevations and spaces or grooves on the case and screw essential so long as they
are fitted to each other, as hereinbefore specified. In Figs. 6, 8, and 9 I have
shown the cutting-elevations 200 as formed on a segmental portion 26, let into the
part D of the case. This can be adjusted to its working position by the clamping
device 13 of the clamp 12, as before described, and, if desired, it may be packed
by one or more sheets of paper or other suitable packing placed between its back
and the bottom of the recess within which it rests, or it may be finished with a
special adjusting-screw 27, as shown in Fig. 9. The other part E of the case may
have a like segment, or the cutting-elevations and intervening spaces may be formed
directly on said part E. The screw has the short cylindrical portion 21 and
web 22, as before described, and other webs 230, divided by the circumferential
grooves 240 into cutting-elevations to fit and bear upon the cutting-elevations
and spaces of the case, substantially as in the construction first described. This
segment of less than half of the case and the two-part case first described will
clearly suggest the idea of making that portion of the case which does the cutting

page_text: in segments of two or more parts adapted to be tightened upon the enclosed
screw.
One advantage of making the working parts-viz., the screw and case-detach-
able from the standard is that a retailer of cut meats may use the cutter and then
place these working parts in his ice-box, where the little meat that remains in the
cutter will keep sweet and clean, leaving the machine in proper condition for use
in cutting meat for the next customer without having to clean the cutter each time.
The compactness of the working parts makes this storage in the ice-box prac-
ticable when it would impracticable in a cutter with the standard permanently
attached.
Instead of notching the clamp on its inner edges to make it take hold of the
ledges on the case it may made in ring form, as shown in Figs. 5 1-2. In either
form the case is held in the standard by its cylindrical portion, which may be
slipped end wise therein, and when the case is detached it bears no special standard
attachment-as, for instance, the stem 25 or a special socket or the like-as has
generally been the case with many meat-cutters.
While I prefer the form of clamping devices herein shown-viz., the clamping
device 13 and clamp 12-it is evident that a screw and case having cutter-
elevations with circumferential spaces or grooves between, all fitted together
as described, may be held in place by ordinary clamping devices, which for the
purpose of this combination I consider the equivalent of those shown.
It should be noticed that the two last spaces at the delivery end of the case have
their bottom extending continuously around the case, and the grooves in the screw
are all preferably formed in the same way while the circumferential spaces toward
the hopper end of the case have the bottoms of the grooves broken instead of
continuous. This permits the cutting to be more gradual, as it leaves at first more
room for the passage of meat without severing the entire body of meat passing
through the machine; but when the meat reaches a point where the bottom of the
space and groove on both the screw and the case is continuous the volume of meat
passing out is necessarily severed, so that no long stringy pieces can escape. I
prefer that the continuous grooves should be the last ones at the delivery end of the
case; but so long as one of them has the continuous bottom the desired result will
be attained even if said continuous bottom is not in the last groove. I also prefer
that most or all of the grooves or spaces having broken bottoms shall be formed
in the case; but a space for the passage of meat around the cutting devices may be
formed by making the bottoms of the spaces or grooves on either part broken.
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 :-
1. The combination of the standard having a clamp 12 formed thereon, the
segmental case fitted for reception in said clamp, and a clamping device for binding
the parts of said case within the standard, substantially as described, and for the
purpose specified.
2. The combination of a case having substantially a cylindrical portion, a
standard having formed thereon a clamp for embracing the cylindrical portion of
said case when it is slipped end wise therein, and a clamping device for binding said
cylindrical portion within said clamp, substantially as described, and for the purpose
specified.
3. The combination of the clamp having the holding notches or recesses, the
clamping device, and the case having the ledges fitted to said recesses, substantially
as described and for the purpose specified.
4. The combination of the segmental case, a screw fitted thereto, and clamping
devices for holding said case and screw together, substantially as specified.
5. The combination of a screw having cutting-elevations with circumferential
grooves or spaces between, a segmental case having cutting elevations and spaces

page_text: fitted in bearing contact with said cutting-elevations and grooves on said screw, and
clamping devices, substantially as described, and for the purpose specified.
6. The combination of a screw having the short cylindrical portion 21,
web 22, and cutting-elevations with circumferential grooves between, a segmental
case having the plain band 19, feeding-ribs, cutting-elevations, and spaces, all
fitted to said screw, and clamping devices, substantially as described and for the
purpose specified.
7. The combination of clamping devices, a segmental case having cutting
elevations with spaces between, and a screw having cutting-elevations and circum-
ferential spaces fitted in bearing contact with said elevations and spaces of said
case, with one circumferential space and groove on said case and screw at the
delivery end, having its bottom extending continuously around the same,
-substantially as described, and for the purpose specified.
