We JOHN HAWKES SANDERS, Novelty Worker, of 320, East 18th Street,
in the City County and State of New York, and JAMES EDWARD CARLIN
Furrier, of 76, Middleton Street, Brooklyn, in the County of Kings, and State
of New York, United States of America, do hereby declare the nature of this
invention to be as follows:--
Our invention relates to a simple durable and rapidly-operating machine which
is adapted to carrot furs and fit them for use in hat-making in a more perfect
manner than said work can be done by hand and which is also so constructed as to
deliver a fine spray of the carrot liquid upon the fur and save the surplus solution
so that there will be no waste.
The machine is provided with a pair of feed rollers mounted one above the other,
the upper feed roller being adjustable vertically and cushioned by springs to provide
for the varying thicknesses of the skins. The feed rollers are geared together and
with a counter shaft adjustable to and from the rollers and driven by a belt from
the main shaft. Immediately behind and parallel to the feed rollers is a rotary
brush which is adapted to act on the fur as it passes between it and the lower feed
roller. The brush is made preferably of corrugated rubber, although it may be
made of other suitable material, and is driven by a belt from the main shaft, the
belt also driving a countershaft journaled near the bottom of the frame. Above
the brush and the upper feed roller is a hood to prevent the carrot solution from
flying, as this solution consists of dilute nitrate of mercury and is very injurious to
the skin of a person. Beneath the brush and extending around and over it is an
atomizer which delivers the carrot solution upon the fur before it passes to the
brush. The atomizer is provided with a tank which is connected with a supply
tank and provided with a discharge pipe rising from a point within and near the
bottom of the tank and which merges with the tank top. The upper end of the
pipe is flattened and enters a blast pipe of flattened section which is curved over
the brush and terminates in a discharge nozzle extending in breadth the whole
length of the feed rollers and situated just behind the upper feed roller so as to
deliver the carrotting liquid on to the fur as it passes over the lower feed roller.
When
The blast pipe is connected with a blower driven from the main shaft.
the fur inserted between the feed rollers is fed downward between the lower
roller and the revolving brush, the current of air from the blower sucks the
up
carrot solution in the tank and delivers the same in a fine spray upon the fur, thus
thoroughly impregnating the fur with the solution and fitting it for the action of
the brush which by pressing the fur against the lower feed roller and acting on it
with its rapidly rotating teeth or corrugations, causes the solution to be thoroughly
worked into the fur. The supply pipe to the tank is provided with a valve to
regulate the flow of liquid and connected with the pipe above the valve is a branch
pipe controlled by a valve and terminating in a loop pipe which passes through the
delivery nozzle of the blower pipe and finely perforated, so that if any accident
happens to the blower the supply to the tank may be closed and the liquid allowed
to flow to and be ejected in a spray from the perforated member of the loop pipe.
A curved guard plate encloses the front portion of the machine the upper end
extending inward to a point between and almost touching the feed rollers and the
lower portion of the guard extends downwards towards the rear of the machine.
Near the lower end of the guard plate is a downward bend to form a gutter which
has a cock-controlled outlet. The guard plate prevents the carrot solution from
flying forward upon the operator and it also prevents the waste of the solution, as

page_text: the surplus solution which drops from above will be caught upon the guard plate
and will run down into the gutter from which it may be drawn when necessary.
Within the guard plate is a fur guide formed of parallel bars united at the bottom
and which permit any surplus solution to drip through upon the guard plate, hold
the furs away from the guard plate, and deliver the same at the rear of the
machine.

COMPLETE SPECIFICATION.
Improvements in Machines for Carrotting Furs.
We, JOHN HAWKES SANDERS, Novelty Worker, of 320, East 18th Street,
in the City County and State of New York, and JAMES EDWARD CARLIN
Furrier, of 76, Middleton Street, Brooklyn, in the County of Kings and State
of New York, United States of America, 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 :-
Our invention relates to improvements in carrotting machines, that is in machines
for carrotting furs; and the object of our invention is to produce a simple durable
and rapidly operating machine which is adapted to carrot furs, and fit them for use
in hat making, in a more perfect manner than said work can be done by hand and
which is also so constructed as to deliver a fine spray of the carrot liquid upon the
fur and save the surplus solution so that there will be no waste.
To this end our invention consists in certain features of construction and combi-
nations of parts which will be hereinafter described and claimed.
Reference is to be had to the accompanying drawings, forming a part of this
Specification, in which similar figures of reference indicate corresponding parts in
all the views.
Figure 1 is a broken rear elevation, partly in section, of the machine embodying
our invention.
Figure 2 is a vertical section on the line 2-2 in Figure 1.
Figure 3 is a broken detail perspective view of the atomizer used in connection
with the machine, and
Figure 4 is a broken detail view of the mechanism for driving the feed
rollers.
The machine is provided with an upright substantial frame 10 in one side of
which are parallel feed rollers 12 and 13 which are mounted one above the other
and journaled in supports 11 on opposite sides of the machine frame. The
supports 11 are slotted vertically and the upper feed roller 13 is journaled in the
slots and is adjustable vertically, the roller being cushioned by springs 14 in a
common and well known manner to provide for the varying thicknesses of the
skins. The feed rollers 12 and 13 are geared together at one end, as shewn in
Figure 2, and at the opposite end one of the rollers is provided with a gear
wheel 15 which meshes with a pinion 16 on a countershaft 17 and the latter is
journaled in a support 18 which is secured to the frame 10 and which is adjust-
able to and from the rollers, the support having a horizontal slot 19 near the
bottom which receives a fastening bolt 20 adapted to hold it to the frame. On
the outer end of the shaft 17 is a grooved pulley 21 (see Figure 1) and this is
driven by a belt 22 from a pulley 23 on the main shaft 24 which is journaled in
the top of the frame and provided with driving pulleys 25. Immediately behind
and parallel to the feed rollers 12 and 13 is a rotary brush 26 which journaled
in suitable bearings, the brush being adapted to act on the fur as it passes between

page_text: t and the lower feed roller 12. The brush is made preferably of corrugated
rubber, although it may be made of other suitable material, and the shaft 27 to
which it is secured is provided at one end with a pulley 28 which is driven by a
belt 29 from a pulley 30 on the shaft 24 the belt after encircling pulley 28 passing
around a pulley 31 on a countershaft 32 which is journaled in a support 33 near
the bottom of the frame. Above the brush 26 and the upper feed roller 13 is a
hood 34 which covers the roller and brush and which extends backwards and
downward through the machine frame, the rear end of the hood being secured to
a cross bar 35 on the frame. The object of the hood is to prevent the carrot
solution from flying, as this solution consists of dilute nitrate of mercury and is
Beneath the brush 26 and extending

around and over it, is an atomizer which is constructed and arranged so as to
deliver the carrot solution upon the fur before it passes to the brush. The
atomizer is provided with a tank 36 which is supported on a cross-bar 37 in the
machine frame and the tank is provided with a discharge pipe 38 rising from a
point within and near the bottom of the tank, as shewn in Figure 2, and which
merges with the tank top 38". The upper end of the pipe 38 is flattened and
enters a blast pipe 39 of Hattened section which is curved over the brush 26 and
terminates in a discharge nozzle shewn at 40 in Figures 1 and 3 extending in
breadth the whole length of the feed rollers and situated just behind the upper
feed roller so as to deliver the carrotting liquid on to the fur as it passes over
the lower feed roller. The blast pipe 39 is connected with a common form of
blower 41 which is supported on cross bars 42 in the machine frame and which is
driven by a shaft 43 journaled in the machine frame and having a pulley 44 at
one end which is driven by a belt 45 from a pulley 46 on the main shaft 24.
When the fur inserted between the feed rollers 12 and 13 is fed downward
between the lower roller and the revolving brush, the current of air from the
blower passes up through the pipe 39 sucks up the carrot solution in the tank 36
and delivers the same in a fine spray upon the fur, thus thoroughly impregnating
the fur with the solution and fitting it for the action of the brush which by pressing
the fur against the lower roller 12 and acting on it with its rapidly rotating
teeth or corrugations causes the solution to be thoroughly worked into the fur.
A pipe 36 leads into the tank 36 and is connected by a pipe 36 with a supply
of carrotting liquid. The pipe 36 is provided with a valve 36° to regulate the
flow of liquid through it and connected with the pipe above the valve is a branch
pipe 36 which is controlled by a valve 36 and terminates in a loop pipe 36¹
which passes through the delivery nozzle 40 of the blower pipe 39 and is finely
perforated. It will be seen then that the tank 36 may be kept supplied with
liquid and if any accident happens to the blower the valve 36 may be closed,
the valve 36 opened, and the liquid allowed to flow through the pipes 36b
and 36 and be ejected in a spray from the perforated member of the loop
pipe 36'.
A curved guard plate 47 encloses the front portion of the machine
frame, the upper end extending inward to a point between and almost touching
the feed rollers 12 and 13 and the lower portion of the guard extends rearward
and downward through the machine frame, the extreme lower end being supported
on a cross-piece 48. Near the lower end of the guard plate is a downward
bend 49 to form a gutter which has a cock-controlled outlet 50. The guard plate
prevents the carrot solution from flying forward upon the operator and it also
prevents the waste of the solution as the surplus solution which drops from above
will be caught upon the guard plate and will run down into the gutter 49 from
which it may be drawn when necessary. Within the guard plate is a fur guide 51
which is very similar to the guard plate in shape and the upper end of the guide
is fixed to a cross bar 52 near the front side of the machine. The fur guide 51
is formed of parallel bars 53 which are united at the bottom and which permit any
surplus solution to drip through upon the guard plate, hold the furs away from
the guard plate, and deliver the same at the rear of the machine.
The operation of the machine is as follows: The feed rollers 12 and 13, the

page_text: brush 26, and the blower 41, are in constant motion and the operator feeds the
skins or furs to be carrotted one after another to the rollers 12 and 13. The
skins are carried inward and downward by the rollers and pass between the lower
roller 12 and the brush 26. At this point the solution of nitrate of mercury or its
equivalent is delivered upon and into the fur by the atomizer; the solution is
then smoothed off by the brush and the skin or fur is delivered upon the guide
bars 51 from which it slides to the rear of the machine.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is
1. A carrotting machine comprising a pair of feed rollers, a rotary brush arranged
behind the rollers and parallel therewith, and an atomizer adapted to deliver
