Machine for Dressing Fur.
We BENJAMIN DUNKERLEY, of Kensington Mills, Glenorchy, Tasmania,
Australia, Hatter and Furrier, and JOSEPH DAVENPORT KAIN, Lowfield House,
Shaw Heath, Stockport, in the County of Chester, Builder, do hereby declare the
nature of this invention to be as follows:-
This invention has for its object the construction of a machine adapted to cut
the hair from the fur of skins, in lieu of by hand work whereby a great amount of
injurious and tedious labour is saved and loss of fur obviated.
To this end our invention consists, firstly, in subjecting the hair of the fur to the
action of an air exhauster and thereby draw the hair over a bed or stationary
knife blade arranged in conjunction with a rotary or other suitable knife or shear
blade.
Our invention consists, secondly, in placing the skins to be dressed on a
perforated hollow surface or support and subjecting its interior to the action of an
air exhauster whereby the skins are caused to adhere securely to the said surface
or support, which latter may form a portion of or a whole circle, or be flat and
moved either in a continuous intermittent or reciprocatory manner or the said
perforated surface or support may be stationary and the aforesaid rotary or other
suitable knife or shear blade rendered relatively movable.
In carrying out our invention, by preference we place the skins to be dressed on
a perforated rotary cylinder, the interior of which we bring into communication
with an air exhauster which serves to draw the skin tightly against the periphery
of the said rotary cylinder and thus fix it thereto without the aid of nails or other
fastenings.
In connection with this rotary cylinder we employ a rotary knife arranged inside
a suitable casing which we also bring in communication with an air exhauster, and
which serves to draw the hair of the fur over a bed or stationary knife blade, so
as to facilitate an exact and uniform cutting of the hair by the said rotary knife.
The latter we render adjustable towards the hair of the fur so as to permit of
altering the amount of cut according to requirements.

Machine for Dressing Fur.
We, BENJAMIN DUNKERLEY, of Kensington Mills, Glenorchy, Tasmania,
Australia, Hatter and Furrier, and JOSEPH DAVENPORT KAIN, of Lowfield
House, Shaw Heath, Stockport, in the County of Chester, Builder, 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 invention has for its object the construction of a machine adapted to cut the
hair from the fur of skins in lieu of by hand work, whereby a great amount of
injurious and tedious labour is saved and loss of fur obviated.
To this end our invention consists, firstly, in subjecting the hair of the fur to the
action of an air exhauster and thereby draw the hair over a bed or stationary

Our invention consists, secondly, in placing the skins to be dressed on a
perforated hollow surface or support and subjecting its interior to the action of an
air exhauster whereby the skins are caused to adhere securely to the said surface
or support, which latter may form a portion of or a whole circle, or be flat and moved
either in a continuous intermittent or reciprocatory manner or the said perforated
surface or support may be stationary and the aforesaid rotary or other suitable
knife or shear blade rendered relatively movable.
And in order that our invention may be more fully understood, we have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a back view, Fig. 2 a plan partly in section and Fig. 3 an end view of
a complete machine constructed in accordance with one form of our invention.
Fig. 4 is a vertical section enlarged of the perforated hollow surface or support,
bed or stationary knife blade and rotary knife.
In carrying out our invention, by preference we place the skins a, the fur a' of
which is to be dressed, on a perforated rotary cylinder b, the interior of which, by
a suitable pipe we bring into communication with an air exhauster (not shown)
which serves to draw the skin a tightly against the periphery of the rotary
cylinder and thus mount it on the same securely without the aid of nails or other
fastenings, in lieu of exhausting the air from the cylinder at one side only, such
may be done from both ends thereof. The cylinder b is suitably fixed on a hollow
shaft c arranged to rotate on a spindle c¹ mounted stationary in bearings d, carried
by a standard or frame e and may be arranged to be brought in and out of rotation
by means of a cone friction coupling ff, or its equivalent, actuated by a hand
lever f. One end of the cylinder b is arranged to rotate in or on a rim d¹ formed
on the respective bearing d, the opposite end of the rim having attached a
pipe leading to an air exhauster. The "he" part of the cone friction
coupling ff, runs loose on the hollow shaft c and has secured on its boss a worm
wheel g arranged in gear with a worm g' fixed on the upper end of a shaft / mounted in
suitable bearings 92 on the standard or frame e and having at its lower end a bevel
wheel gearing into another bevel wheel 2 fixed on the driving shaft i which
latter carries at the opposite end a loose and two fast pulleys k, k¹ & k²,
respectively.
In connection with the rotary cylinder b, we employ a rotary knife having on
its axis 62 a pulley 63 to which rotary motion is imparted from the pulley k², on the
driving shaft i, by means of a belt k³. The rotary knife is arranged inside a
suitable casing m, which by means of a suitable pipe m', we also bring in
communication with an air exhauster (not shown). The casing m on its side
opposite to the cylinder b has a slot or opening m², see Fig. 4, which permits the
said exhauster to draw the hair of the fur a¹ over a bed or stationary knife blade l¹
and thus facilitate an exact and uniform cutting off of the hair from the fur by the
rotary knife 1. The bed or stationary knife blade is attached to a stock 2,
carried by sockets 13, rendered laterally adjustable in a bracket 1 by means of the
screw and the latter bracket 1 vertically by the screw 16. The ends of the rotary
knife are mounted in blocks n carried by brackets n' attached to screwed stoods o
projecting from brackets o¹, secured to the standard or frame e, the blocks n being
rendered laterally adjustable by the screws m³ and the brackets n' by the nuts o²,
whereby the length of hair to be cut off the fur a¹ can be altered and the wear of
the bed or stationary knife blade l' and rotary knife 1 compensated for as may be
required. The exhauster pipes 6¹ & m¹ may be brought into communication with
one exhauster only or with separate exhausters of any suitable construction
employed at the machine itself or a distance away from the same as may be found
most convenient, and the perforated hollow surface or support 6 may be made in
size as may be required for different sizes or kinds of skins a.
It will be evident that the means for drawing the hair of the fur to be dressed

page_text: over a bed or stationary blade whilst being cut and the cutting arrangements
described may be employed apart from the means described for mounting the skins
without departing from the nature of our invention.
The working of the invention is as follows
-
Assuming the "he" part f is out of contact with the "she" part f¹ of the cone
friction coupling the interior of the cylinder and the hair and fur are exposed to
the action of the exhausters as described, the driving shaft is set in rotation by
placing the strap onto the fast pulley and thus transmits motion by means of the
bevel wheels 2, h, shaft h, worm g, to the worm wheel g' and "he" part of the
cone friction coupling as well as to the rotary knife by the pulleys k, k¹, & k², and
strap. The skin is then placed on the cylinder and thus exposed to the action
of the exhauster, which instantly draws it tight onto the periphery of the cylinder,
after which the "he" part is brought into contact with the "she" part 1 of the
cone friction coupling,f, by means of the lever f2 and thus the cylinder b set in
rotation. The hair of the fur arriving opposite the slot or opening m² is then
drawn over the bed or stationary knife blade by the exhaust created in the
casing m and the projecting portion or hair cut from the fur by the rotary knife l.
After the cylinder has made one or more revolutions its rotation may be inter-
rupted by throwing the cone friction coupling f,1', out of contact with the lever f²
which permits the removal of the fur now dressed, or the latter may be effected
during the rotation of the cylinder b.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim, is-
"In fur dressing machines."
1st. The general construction and combination of parts operating substantially
as and for the purpose set forth.
2nd. The employment of a hollow perforated surface or support b, the interior of
which is subjected to the action of an exhauster, adapted to secure, by suction, onto
the said surface or support the skins to be dressed, substantially as and for the
purpose set forth.
3rd. In combination, the surface or support for holding the fur, the shearing
knife, the casing m enclosing said shearing knife, the interior of which is
subjected to the action of an exhauster, the means for adjusting the shearing knife !
to and from the surface or support b, the bed or stationary knife blade arranged
to act in conjunction with the shearing knife and means for adjusting same
laterally and vertically, substantially as and for the purpose set forth.
