COMPLETE
Fur Plucking Machines.
I, ISIDOR DRESDNER of No. 118 Graham Avenue in the City of Brooklyn and
State of New York, United States of America, Merchant 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 :-
In plucking furs by machines, rather than by hand, as usual, it has been
found impracticable to make the action of the machine continuous, such as would
be produced, for example, by smooth plucking rollers rotating always in contact.
Rather is it necessary that the action of the machine should be intermittent in
order to permit the operator to handle the skin properly. It has been sought
generally to secure this intermittent action by vibrating nipper jaws and in one
case by a rotary plucking machine which consists essentially of a roller formed
of radial blades carried upon a shaft, the blades being set at such a distance
apart that no two blades shall at the same time act upon the hairs to be plucked.
By these means the action of the blades is caused to be intermittent and the fur
is released entirely between the action of two successive blades. This machine
operates satisfactorily upon some kinds of fur but on other kinds the hairs to be
plucked are so delicate that, they are blown back by the current of air produced
by the blades, or are caused to curl by the constant friction with the result that
the pelt is only partially plucked. It is the object of my present invention to
produce a machine of the rotary type which is especially adapted for operating
upon furs of the character just referred to and which shall operate in such a
manner as not to blow back or curl the fine hairs but shall pluck the pelt com-
pletely at a single operation. I employ a continuously driven roller as before, but
insplace, of a roller with a circumferential series of radial blades I use a roller
which may have one or, at the most, two blades and I mount the co-operating
roller in movable bearings so that it may be reciprocated toward and from the
other roller..

driving, wheel indicated in dotted lines.
Fig. 3 is a partial longitudinal section on the line of Fig. 2; and
Fig. 4 is a partial transverse section on the line y-y of Fig. 1.
The frame of the machine may be of any suitable construction and comprises
standards 10, 10, and cross-bars 11, 12. The standards 10, 10, are adapted to be
secured to a suitable table 13. In fixed bearings in the standards is supported
to rotate freely a shaft 14, which may have attached a driving pulley 15, or
other means for rotating it, and also carries a 'roller 16. Above the shaft 14,
the "standards are slotted as at 17, and form ways 18, to receive and guide the
frames 19, which are movable on said ways. These frames 19, support..the
bearing boxes 20, for a co-operating roller 21, of some such material as rubber,
and in order, that this roller may be made adjustable with reference to the
roller 16, and in order, to regulate the contact between the two 'rollers and to
take up wear, springs 22, are interposed between the lower ends of the frames
and the boxes, and screws 23, are tapped into the other ends of the 'frame to
bear upon the boxes aad to adjust their position by compressing the springs
more or less. 23

The roller 16, may be formed in any way to adapt it to the particular work
to be performed, but I prefer to construct it as represented in the 'drawings,
wherein one or two blades 24, are secured to the shaft 14.

page_text: It is necessary, as stated above, that the action of the roller should be intermittent,
that it should be quick, and that the hairs should be in the proper position relative
to the two rollers. In order to secure these desirable results, without encountering
the evils alluded to, I cause the co-operating roller to be reciprocated bodily toward
and from the continuously rotating roller 16.
Therefore I fix upon the shaft 14 eccentrics 25, 25, and I connect the straps 26,
of these eccentrics to the frames 19, which support the co-operating roller, so that
as the shaft 14, is rotated it will, at each rotation, move the roller 21, toward and
from the roller 16, whereby, when the edges of the blades 24, meet the roller 21,
the hairs of the pelt lie over them in such position as to be plucked out by the con-
tinued forward rotation of the two rollers.
In front of the bite of the rollers I support a comb, consisting of teeth 27, fixed
to a plate 28.
The comb is made adjustable toward and from the rollers by bolts 29, 30, in an
ordinary manner.
To support the pelt in front of the comb and rollers I employ a rod 31, which is
bent substantially in U-shape and then is bent again at about right angles as
shown so that the two members may be pivoted to the table 13, and the transverse
part 32, of the rod be brought about in line with the bite of the rollers. Springs 33,
may be attached to the rod and the table so as to keep the transverse part of the
rod normally from the comb while a U-shaped body frame 34, may be provided
with a finger 35 to rest and slide upon the table so that its upper portion may be
pressed forward by the body of the operator.
In order to free the roller 21, and the blades 24, from the hairs which cling to
them after being plucked out, I place in the rear of the plucking devices a rotary
brush 36, the bristles of which sweep the roller and the blades. This brush may
be mounted and driven in any desired manner but I have shown it as mounted
upon a shaft 37, which has a bearing in a cross-bar 38. Above the bar 38, the
shaft is provided with a pulley 39, which is driven by a convenient arrangement of
bands 40, 41, and intermediate shaft 42, having pulleys 43, 44, from a pulley 45, on
the shaft 14.
In the operation of the machine a pelt is thrown over the transverse portion 32,
of the rod 31, and is held thereon by the operator with both hands.
By a forward movement of the body of the operator against the body-frame 34,
the pelt is then thrown forward so that the long hairs shall project through the
comb and toward the bite of the rollers. As the shaft 14, is rotated the blades of
the roller 16, will raise the hairs and immediately thereafter the roller 21, will
descend and cause such hairs to be firmly grasped between itself and the blades
and to be quickly plucked out by the continued rotation of the two rollers together.
At once the roller 21, will rise into position for another action and the pelt will
be shifted by the operator.
It is obvious that if desired the positions of the rollers might be reversed and the
bladed roller might be reciprocated, but I prefer the action of the arrangement
shown.
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 :-
1. In a fur-plucking machine, the combination of a bladed roller, a second roller
to co-operate with said first named roller, means to rotate one of said rollers, and
means to reciprocate one of said rollers toward and from the other substantially as
shown and described.
2. In a fur-plucking machine, the combination of a bladed roller, means to rotate
it, eccentrics carried by the shaft of said roller, a roller to co-operate with the
said bladed roller, and sliding boxes for said co-operating roller adapted to be
reciprocated by said eccentrics, substantially as shown and described.
3. In a fur-plucking machine, the combination of a pelt-supporting device, a

page_text: continuously rotating roller, a co-operating roller mounted in movable bearings,
means to reciprocate said roller bodily, and a comb interposed between the
pelt-supporting device and the bite of said rolls, substantially as shown and
described.
4. In a fur-plucking machine, the combination of a bladed roller, a second roller
to co-operate with said first named roller, means to rotate one of said rollers, means
to reciprocate one of said rollers toward and from the other, and a brush to free
said rollers from the clinging hairs, substantially as shown and described.
