COMPLETE SPECIFICATION.
A Fur Cutting and Blowing Machine.
I, WILLIAM DAWSON BOOTH, of King Street West, Stockport, in the County of
Chester, Agent, do hereby declare the nature of this invention, which has been com-
municated to me from abroad by George Yule, of the Yule Machine Company, of 40,
Burnett Street, Newark, New Jersey, U.S.A., Manufacturers of Hatting Machinery,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The object of this invention is to provide a machine whereby the fur on bits of
rabbit, hare, beaver, rutria and the like skins which are torn off whole skins in
the process of cutting the fur from the latter as well as the cutting of the tails of
the said animals is performed in connection with a fur blowing machine auto-
matically in lieu of separately by hand, thus saving a great amount of labour.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference indicat-
ing like parts in the various figures, Fig. 1 being a side view partly in section and
Fig. 2 a plan of a fur cutting and blowing machine complete arranged in accor-
dance with one form of this invention. Fig. 3 is a side view and Fig. 4 an end
view of the fur cutting device separately and Fig. 5 a cross section of a detail.
In carrying out this invention and referring to the Figs. 1 & 2, a, a¹ represent
a fur blower, 6, 61 the fur cutting device and c, c¹ an automatic fur feeder.
The fur blower a and automatic feeder c may be of any suitable or the usual
construction and the fur cutting device b, b¹ which is employed between the former
constructed preferably as follows;-
Upon a suitable part of the frame a¹ of the said fur blower is secured a casing
formed in two parts b, b' in which is suitably mounted a drum d furnished on its
periphery with a suitable number of knife blades d' arranged spirally at equali
distances apart from each other. In the front of the bottom half 6 of the said
casing, see also Fig. 3, a bed plate or stationary knife e is rendered diagonally!
adjustable towards the cutting edges of the knife blades d¹, see also Fig. 5, and
the upper half 6' is formed with a hopper 62 hinged to the lower half 6 of the said
casing so as to allow of being thrown back into the position shown in dotted lines
Fig. 1, and thereby give access to the rotary knife drum d, d¹ when required. The
knife drum d, dis mounted in the upper half 61 of the said casing and rendered
adjustable upon the lower half 6 by means of set screws 6³, see Figs. 3 & 4, in
order to bring the cutting edge of the knives d' nearer to or further away from that
of the bed plate or stationary knife e as may be required.
The skin and tails from which the fur is to be cut are placed into the feeder c,
thereby lifted and through the funnel c dropped into the hopper 68 upon the
knife drum d, d. This knife drum is rotated at a high speed in the direction of the
bed plate or stationary knife e and subjects the said skin bits and tails to the action
of the said knives which frees them from the fur.
Below the knife drum d, d' is employed a travelling endless apron f upon which the
skin bits and tails and fur cut from the same, drop and which carries same forward

page_text: between a pair of rollers g, g. These rollers submit the fur and skin bits and tails
to the action of a pin roller h adapted to separate the fur from the skin bits and tails,
the former being drawn away by the fan of the blower and deposited into a suit-
able receptacle at the end of the blower and the latter allowed to drop upon another
travelling endless apron i employed below the said rollers and first named apron
and adapted to return the skin bits and tails to the feeder c to be again treated at
the will of the operator.
It may be remarked that the automatic feeder c, c¹ is not an essential part of the
combination as the skin bits and tails to be treated may be placed into the hopper 12
by hand.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1st. The combination of a device for cutting the fur of skin bits and tails with a
fur blower operating substantially as and for the purpose set forth.
2nd. In a machine such as specified in the preceding claim, a fur cutting device
consisting of a drum d having on its periphery a number of spirally arranged
knive blades d' operating in conjunction with a bed plate or stationary knife blade e
and a travelling endless apron f adapted to receive the skin bits and tails and fur
dropping from the said knives and carry the same into the blower, all substantially
as set forth.
3rd. In connection with the cutting device specified in the preceding claim,
and a fur blower, a travelling endless apron i adapted to receive the skin bits and
tails which drop in the blower and return same to the said cutting device, all sub-
stantially as set forth.
