FUR CUTTING MACHINE
Oscar M. Dean, Sioux City, Iowa
Application January 16, 1935, Serial No. 2,111
37 Claims. (Cl. 164-50)
My present invention relates generally to the
Figure 1 is a left side elevation, the left side
art of cutting fur bearing hides, or more par- frame half being removed.
ticularly to the art of notching the edges of fur

bearing hides which are to be sewed together,
5 and primarily has for its object to provide a
machine embodying novel mechanisms for per-
forming this function.
It has been discovered in the fur garment industry that the line of stitching between two
10 skins can be fairly well concealed by providing
the edges of the skins with inter?tting notches
and sewing the skins together along the edges
of these notches. It has also been found di?icult to out fur bearing hides along any desired
15 line without objectionably severing hairs of the
hide during the cutting process. In Patent
1,895,025 issued January 24, 1933, I disclosed
a novel method of cutting fur bearing hides
along a desired line without objectionably
20 severing hairs, the particular line disclosed being the desired notched or zig-zag line. The
mechanisms disclosed in that patent as an ex- ‘
ample of means adaptable for performing the
method inciuded a slender cutting element tri25 angular in cross section, means to reciprocate
the element, means to advance the hide past the
element, and means to translate the e1ement
back and forth across the path of travel of the
hide in timed relation to the speed of advance30 ment of hide to cause the individual cuts or
punctures formed by the element in the hide to
conjointly form a continuous zig-zag or notchedline out in the hide.
In its more detailed nature, my present inven35 tion seeks to provide a novel fur cutting machine embodying certain new and useful improvements over the mechanisms disclosed in my
patent above referred to and including a novel
slender, flat blade cutting element; novel means
40 for reciprocating the element; novel means for
translating the element back and forth across the
line of advancement of the hide; and novel
means for changing the position of the element
at the termination of movement of translation
45 in each direction so that the ?at of the blade
will be presented in the line of cut at all times,
thus avoiding mutilation of the hide along either
side of the line of cut.
With the above and other objects in view
50 which will more fully appear, the nature of the
invention will be more clearly understood by following the description, the appended claims, and

In the drawings in which like numerals of ref
erence indicate like parts in 3111 the figures, I
have disclosed a frame or casing for housing the
mechanisms of the machine and comprising com
elementary half members 5 and 6 removably se
cured together by screws 1. The half members
together form a base 8, a Standard 9, an Over
hanging arm I", and a front head portion H
for accommodating the various mechanisms of
the machine.
Aside from One feed Teller and its driving pin
1011, all 0f the mechanisms of my improved me
Chine are Supported in the half member 5 and
are accessible by removal of the half member
e and for this reason the frame section 5 is pre- 45
vided with horizontal shaft bearings 12, vertical
shaft bearings I3, and horizontal slide guides l4.
A main drive shaft I5 is rotatably supported
in the bearings I2 and projects from the rear
end of the frame where it is equipped with a driv- 50
ing pulley l6 and a hanclwheel I1. Within the
frame, the shaft l5 also carries a worm l8 which

shaft 20 suitably journaled in the frame halves,
In the drawings:—
and the shaft 20 also carries a worm 2! which 55

2,073,194
meshes with a worm 22 mounted on a shaft 23
rotatable in the vertical bearings I3.
At its lower end the shaft 23 carries another
worm 24 which meshes with a worm 25 mounted
on the drive shaft 26 which is rotatable in bear
ings 21 provided therefor in the frame half 5.
At its front end the drive shaft 26 projects into
the front head portion I! where it is equipped
with a driver pinion 28, the purpose of which will
10 become apparent as the description progresses.
A cutting element supporting and translating
slide or carriage 29 is supported in the slide guides
l4 and is movable back and forth in said guides
for imparting back and forth or reciprocatory
movement of translation to the cutting element
tance above the enlargement and the cutter ‘bar
accommodating opening in this extended portion
of the sleeve is squared or otherwise non-cir
cular to cooperate with a non-circular portion 41
of the cutter bar in permitting said cutter bar
to reciprocate longitudinally Within the sleeve
but assuring rotation of said sleeve about its
axis with the cutter bar.
An abutment collar 48 is secured to the upper
end of the vertical extension of the sleeve 44 and 10
beneath this collar a coil spring 49 encircles the
sleeve extension and has its respective ends so
engaged with pins 59 projecting from said collar
and a winding ratchet collar 51 encircling the
sleeve extension below the spring as to cause the 15
in a manner and for a purpose later to be de
spring to constantly tend to rotate the sleeve 44
scribed. The carriage 29 is retained in the guides
M by removable plates 39 and is equipped at its
front end with upper and lower bearing exten
sions 3|, and at its rear end with two diametri
cally oppositely disposed cam ears 32 providing
an axially extending cam portion in the nature
and the cutter bar 4i about their common axis.
of a crown cam having the cam surfaces there
of which form the projections and depressions or
notches bearing approximately 90° angular rela
tion.
The cars 92 of the cam portion extending axi
ally from the rear end of the slide carriage 29
are adapted to engage and cooperate with similar
30 cars 33 or crown cam portions projecting from
a spur gear rotor 34 which is freely rotatable
about the axis of the shaft i5 and adapted to be
driven by the gear 35 secured upon the drive
shaft 26. It will be understood that by reason of
the Worm gear connections hereinbefore de
scribed the relatively rapid rotation of the main
shaft l5 will be transmitted in. the form of very
slow rotation to the drive shaft 26 and the crown
cam portion 33 and hide advancing pinion 28 to
40 which it imparts motion.
See Figures 3 and 4.
The winding ratchet collar 5! is equipped with
four teeth disposed in equidistantly spaced rela 20
tion about the axis of the collar and opposed, at
opposite sides, as shown in Figures 1 and 4 of
the drawings, by a pair of oppositely effective
spring energy holding and restoring fingers 52
which are pivotally supported as at 53 upon the 25
rearmost slide guide l4 and held against the
opposite edges of the ratchet collar by a retrac
tile spring 54.
A stop and release member 55 is pivotally sup
ported upon the upper bearing extension 3| of 30
the slide 29 in position for having the stop re
leasing ?ngers 55 thereof alternately engage with
the stop lugs 49 projecting from the enlarge
ment of the sleeve 44. The member 55 includes
an actuator arm extension 51 which projects 35
between and is adapted to engage one or an
other of a pair of spaced adjustable abutment
stops 58 at the end of movement of translation
of the slide or carriage 29 in a given direction.
It will be noted that while the stop lugs 46 are

alined with the main shaft 15, and by reason of
the spline connection between these shaft sec
tions l5 and 3'! they in effect constitute a single
of the stop and release member 55 bear 90° an
gular relation. By reference to Figure 8 of the
extensible shaft, the portion 31 being capable of
longitudinal movement back and forth with the
slide 29. At its front end the shaft section 31
projects from the carriage 29 and is equipped
with a crank disc 98 having an off center an i
friction crank roller 39 which operates in a
cross slot in a slide block 49 which supports and
imparts vertical or axial reciprocation to the
cutting element carrying bar 4!. The bar 4! is
free to rotate about its axis in the block 49 but
is held against longitudinal movement relative
to the block by collars 42.
At its lower end the cutter bar is provided with
any suitable form of clutch in which the cutter
element 43 may be removably secured. In this
disclosure the hide cutting element is in the
nature of a flat, slender, or narrow element hav
ing two cutting edges merging in a central pierc
ing or penetrating point.
The cutter bar 4| has ordinary reciprocable
bearing in the lower carriage extension 3! but
in the companion or upper extension .35 said
drawings, it will be understood that as the car
riage 29 advances forwardly in the direction of 45
the arrow, and has approximately completed its
movement in that direction, the actuator arm 57
will engage the foremost abutment 58 and the
position of the stop and release ?ngers 56 shown
in full lines will be changed to the position shown 50
in dotted line thus releasing the then held or
stopped lug 46 and permitting it, the sleeve 44
and the cutter bar 4|, to rotate 90° about their
common axis in clockwise direction and then to
be stopped by the remaining ?nger 55 which
has been projected into the path of movement
of the lug 45 as shown in dotted lines in Figure
8. At the conclusion of movement of the car
riage 29 in the opposite direction the arm 5'!
will engage the rearmost abutment 58 and re 60
verse the position of the ?ngers 56 or in other
words return them to the position illustrated in
full lines in Figure 8 thus releasing the lug 46
and permitting the cutter element assembly to
turn from the dotted line position to the full
line position illustrated in Figure 8.
It will be observed by reference to Figure 4 of
bar passes through a bearing sleeve 44 which is
the drawings that one or another of the ratchet
held against longitudinal movement relative to
the carriage by a collar 45 encircling and secured
70 to its lower end by an enlargement just above
the upper extension 3! and which is equipped
with two diametrically oppositely disposed stop
collar-engaging ?ngers 52 will always be in en
gagement with one of the teeth of said collar
thus holding the tension stored in the coiled
spring 49. It will be apparent also that as the
cutter element assembly is rotated 90° about its
axis as above described some of the tension stored
75
lugs 48 as best shown in Figures 3 and 8 of the
drawings. The sleeve extends a considerable dis
in the spring 49 will be released in effecting this
2,073,194
movement.
The spring tension thus lost is re
stored and the spring always retained at desired
efficiency in the following manner. Each time
the carriage 29 moves forwardly or rearwardly
it carries the cutting element assembly including
the ratchet collar 5| with it and as the ratchet
collar 5| is moved back and forth between the
?ngers 52 one or the other of the ?ngers is always
active to impart a degree of rotation to the collar
tending to wind or store energy in the spring 49,
and this restoration of energy is always suf?cient
to compensate for losses incident to the rotation
of the cutting assembly about its axis.
The frame halves 5 and 9 have open portions
; at the front which cooperate to form an opening
59 through which access may be had to the cut
ting element assembly. See Figures 1 and 2. The
opening 59 is accessible through a removable
plate 60.
Each of the frame halves 5 and 5, in the front
portions thereof which together form the head
portion 1 l, carries a hide advancing or feed roller
El mounted on a shaft 62 journaled in the re
spective frame half portion and equipped with
L’ "a driven gear 63.

vsize for accommodating the translatory move
ment of the cutting element and also for permit
ting freedom of hairs of the hide in the cutting
area so that they may be de?ected by the cutting
element.
Brackets 8| are secured to the carriage 29 and
rods 82 extend from the brackets and enter re
ceiving sockets 83 in the foremost slide guides 14.
The rods 82, are encircled by the coils of com
pression springs 84 which are interposed between ,10
the brackets 81 and the bearing, l4 and serve
always to urge the carriage 29 rearwardly thus
constantly holding the crown vgear portion 32
thereof in engagement with the companion cam
equipment 33.
At its upper end the cutter bar 4| is extended '
through a longitudinal opening in the frame and
equipped with a knurled head 85. This equip
ment makes it possible to manually manipulate
the cutter bar to hold it stationary while manip
ulating the cutting element securing clutch, to
manually change the angular position of the
element, or to manually restore tension in the
spring in case of any emergent condition of use.
When the frame halves are
assembled as shown in Figure 2 of the drawings,
the gears 63 of the respective rollers mesh with
a centrally mounted driver gear 64 rotatably sup
ported on the stud shaft 65 secured in the frame
half 5, and to this driver gear slow rotation is
In operation the rapid rotation imparted to the
shaft l5 will be transmitted in the formofrapid
vertical or-axial reciprocation to the cutter bar
41 by the disc 38 and roller 39. The rapid rota
tion of the shaft l5 will likewise be transmitted

portion 33 and hide advancing rollers 6| driven
referred to. In this manner the feed rollers BI
are rotated slowly and in constantly timed rela
tion to the sliding or translatory movement of
the carriage 29 and the hide cutting assembly
movable therewith.
A brake cam 66 is ?xed to or formed integral
with the crown cam and gear 33, 34 and includes
in the form of relatively slow rotation to the ~
therefrom. It will be obvious also that by reason
of the slow rotation of the cam portion 33 and its
engagement with the cam portion 32 the carriage -"

and forth moving the reciprocating cutting ele
ment slowly back and forth across the path of

A brake
arm 68 is pivotally supported at 69 on the frame
forth across the path of advancement of the
half 5 and includes an overhanging ?ange por
tion 10 and a brake shoe ‘H for cooperating with
hide in constantly timed relation, is the forma
tion of a continuous zig~zag or notched-line out,
a the cam surfaces. The arm 68 is pressed against
each zig x and each zag y of such out being
formed by a rapid succession of individual nar
row cuts formed by the cutting element as illus
the cam by an adjustable compression spring 12
and exerts a pressure thereon which serves to
govern the rotation of the cam portion and pre
vent accelerated relative movement of the parts
at any time. As the high points of the cam por
tions 32 and 33 are passing, at which time the
greatest tendency for accelerated movement of
the cam and gear unit 33, 34 or the carriage 29
occurs, the brake arm will then be in engagement
with one of the high points of the cam and will
therefore be exerting its maximum braking effi
ciency in order to effectively overcome this
tendency.
'
The hide advancing or feed rollers 6| are op
(if posed by a work plate 13 supported upon a rocker
arm 14 pivoted as at 15 to the frame. The plate
13 is tiltably supported on said arm, being piv
otally supported thereon at 16 and ‘H, the pivots
being arranged with their axes in right angular
relation so as to in eifect form a universal tilt
mounting for said plate. A compression spring
18 engages the arm 14 and yieldably presses the
plate '13 and the hide supported thereon against
the rollers 6|. A push rod 19 attached to a suit
able treadle (not shown) may be utilized to
separate the plate from the rollers for the pur
pose of insertion and removal of a hide.- The
plate is provided with a longitudinal opening 80
disposed between the rollers 6| as shown in Fig
75 ures 9 and'll, said opening being of a shape and
trated in Figures 9 and 10. In forming this cut
the ?at of the narrow cutting element always
alines with the line of cut so as to assure a smooth 50
edge out. This is made possible because any
given unit or distance of hide advancement is
attended by a like unit or distance of translatory
movement of the cutting element and consequent
ly the piercing or penetrating point of the ?at :ex Ci
cutting element will always strike the hide in
the desired line of cut as shown in Figure 10,
and at the completion of the succession of cuts
forming each zig or zag, and while the cutting
element is elevated out of contact with the hide,
‘the element is rotated 90° about its axis as here
inbefore described so as to aline the ?at thereof
with the zig or zag next to be cut.
The number of cutting element reciprocations,
or in other words the number of successive in
65
dividual cuts, utilized to form the individual zigs
and zags of the continuous line out may vary but
always are relatively narrow so as to enable the
narrow element to pass between the hairs de
?eeting but not cutting the same.
70
In diagrammatic Figure 10 the heavy dots serve
to indicate the individual points of penetration
and the crossed light lines therefore illustrate
what might be termed units of movement, of ad
vancing movement with respect to the-hide, and 75
4
2,073,194
of movement of translation with respect to the
cutting element. It will be observed that the
points of penetration are spaced apart a distance
less than the width or major cross sectional area
of the cutting element. Thus positioned a con
tinuous line out is assured. When the piercing
or penetrating points are spaced apart a distance
10
less than half the width of the element as shown
in Figure 10, one cutting edge alone of the ele
ment will be effective in forming the line out in a
given direction.
In this particular disclosure the cutting assem
bly is rotated step by step, one-quarter of a turn
at a time, always in one direction, and thus, in
this particular disclosure, as shown in Figures 9
15
and 10, a given edge of the element forms a zig,
the element is turned 90° about its axis, and the
same edge forms a zag upon the completion of
which the element is again turned 90° about its
axis and the other edge will then be effective to
20
form a Zig and a zag in a like manner and so on.
It is of course to be understood that the details
of structure and arrangement of parts may be
variously changed and modi?ed without depart
ing from the spirit and scope: of my invention.
