Improvements in Machines for Carrotting Pelts or Skins in the
Manufacture of Felt.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 :-
My invention relates to improvements in carrotting machines, such as are used
in carrotting pelts or skins to fit them for use in hat making, and the object of my
invention is to produce a simple, durable and comparatively inexpensive machine
into which the pelts may be fed, one after another, and through which the pelts
will run, coming out of the machine completely finished and ready for use, the
acid being meanwhile automatically and evenly applied to the pelts, and the pelts
manipulated in such a way as to cause them to be very nicely carrotted, in fact
treated better than they would be by hand.
To these ends my invention consists of certain features of construction and
combinations 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.

page_text: Figure 13 is a broken detail plan view of the bearing roller used instead of the

Figure 14 is a detail side elevation showing a gear mechanism which can be
used to advantage in driving the parts illustrated in Figure 11.
The machine is provided with a suitable frame 10, which may be of any approved
design, and in the front part of the machine are feed rollers 11 and 12, which are
arranged one above the other, and the office of which is to feed the pelts or skins
into the machine, the rollers being preferably rubber covered in order that they
may grip the pelts well.
The upper roller 11, as well as the upper rollers and movable parts hereinafter
described, is mounted in vertically movable boxes 13, which have hollow posts 14
on them, (see Figure 8) and the posts fit in hollow screws 15, which turn in rigid
supports 16 on the machine frame, and the screws have holes 17 to receive a key.
or squared heads 18 (see Figure 5) to receive a wrench, so that they may be
easily turned. Within the screws and posts 15 and 14 are stiff spiral springs 19,
which press downward on the boxes 13, and by adjusting the screws 15 the tension
of the springs and the pressure of the boxes may be regulated.
The rollers 11 and 12 are driven by means of meshing gear wheels 20, but it
will be understood that while I describe and show certain forms of gearing, the
moving parts of the machine may be driven in any usual way.
The lower gear
wheel 20 meshes with an idler 21, (see Figure 4) which is driven by a gear
wheel 22 on the driving shaft 23, which shaft is provided with a driving pulley 24
(see Figure 2) or equivalent means of driving it, and the shaft is supported in a
bracket 25.
In front of the upper feed roller 11 and near the lower side thereof is a guide
roller 26, which is also preferably rubber covered, and beneath this is an apron 27,
which is movable up and down, and which prevents the acid from being thrown
out of the front end of the machine. The apron moves in slide-ways 28, and is
provided with arnis or flanges 29, which are engaged by levers 30 on the cross
rod, or shaft 31, journaled in the machine frame, and the front ends of the levers 30
are provided with cables 32 carrying weights 33, and the pressure of the weights 33
tilts the levers 30 and holds up the apron 27, but holds it yieldingly so that the
apron may be pushed down when necessary. A spring may be substituted for the
weights if desired.
It will be seen that a pelt can be fed through between the roller 26 and
apron 27, the latter being pushed down to permit the pelt to enter the machine,
after which the feed rollers 11 and 12 draw it further along. The pelt is carried
from the feed rollers to the pelt bearing or scrubbing table 34, which is preferably
of the form shown in Figure 3, being of a generally triangular shape in cross
section and having a generally flat top surface with cross corrugations 36 therein
to prevent the pelt from slipping sidewise.
The bearing or scrubbing table 34 has end trunnions 35 (see Figure 6) which
are adapted to rest on the frame 10, and at intervals on the front and rear edges
of the table are recesses 37 through which the surplus acid may drop.
Turning above the table is a brush 38 adapted to scrub the acid into the pelt as
the latter passes between the brush and the table 34. The brush 38 is mounted
in vertically adjustable bearings like the rollers already described, and it has at
one end a gear wheel 39 (see Figure 9) which is driven by a cone idler gear 41,
the smaller part of which meshes with and is driven by a gear wheel 42 on the
shaft of the roller 12. This provides for giving the necessary speed to the brush.
The acid can be delivered to the pelt as it passes to the brush 38 in many ways,
but a jet pipe 43 is preferably employed, which pipe extends across the machine
above the brush and is held in suitable clamps 44, as shown in Figure 3. This
pipe can be fed from a source of supply by means of a supply pipe, but it is
usually supplied by a pipe 45, which connects with a pump 46, and the latter draws
the acid by means of a pipe 47 from a tank 48 beneath. the machine, and the tank
connects by means of a pipe 49 with the acid pan 50, which is arranged beneath

page_text: the brush 38 and the several rollers of the machine, so that the surplus acid is
caught in the pan and runs back into the tank 48. The jet pipe 43 has a vent
pipe 43.
may be supported in any convenient way, but is preferably
provided with flanges 50 and 50, (see Figure 3) which rest on cross rods 50° in
the machine.
The pan
50
The pump 46 may be of any usual kind, but its piston rod 51 slides through a
guide 51 (see Figure 2) and connects by a connecting rod 52 with a crank pulley 53.
on the driving shaft 23. It will be seen then that when the machine is in operation
the pump will constantly supply the jet pipe 43, while the acid which has been
used will collect in the pan 50 and run back through the pipe 49 into the tank 43.
Instead of the bearing table 34 a circumferentially corrugated roller 34° (see
Figure 13) may be used, and the roller is provided with a gear wheel 54 to mesh
with other gear wheels, so that the roller may be turned and the skin or pelt
carried over it, and in this case the jet pipe and roller are covered by a hood 55 (see
Figure 11) extending across the machine top, which prevents any acid from flying
out of the machine.
After passing the bearing table or roller 34*, as the case may be, the pelt is
caught by the wringing rollers 56 and 57, which are preferably rubber covered,
and are arranged one above the other (see Figures 3 and 11) and the upper roller
is journaled in yielding bearings, as already described. These rollers carry the
pelt along and squeeze out the surplus acid as the pelt passes between them, and
the rollers are turned by means of meshing gear wheels 58, (see Figures 4 and 14)
'one of which meshes with the idler 21.
as shown
After leaving the wringing rollers the pelt is passed over a polishing roller 58ª,
(see Figures 3 and 12) which is preferably rubber covered and turns in yielding
bearings 58, which are supported on springs 58° (see Figure 3). The polishing
roller 58 turns beneath a polishing table 59 just above it, and the back side of this
table is preferably shaped to fit the upper wringing roller 56. Instead of these
polishing devices just described, however, the machine may be arranged
in Figure 11, where a polishing table 60 is arranged behind the wringing rollers
and a rotary polishing brush 61 arranged to turn on the table. In either event
the skin or pelt is passed from the machine to a carrier or belt 62, which turns over
rollers 63 and 64, the former being journaled on the machine frame 10, and the
latter on supports 65 (see Figure 1).
The roller 63 has at one end a gear wheel 66, which is turned by an idler 67,
and the latter is driven by one of the gear wheels 58. The roller 63 has at its
opposite end a gear wheel 68, which engages an idler 69 (see Figure 9) and this
turns a gear wheel 70 on the shaft of the roller 58. Where, however, the machine
has its parts arranged as in Figure 11, the driving gears are slightly changed, as
shown in Figure 14, and in this case the roller 63 has at one end a gear wheel 71
driving a gear wheel 72 on the shaft of the brush 61, and the roller 34 is driven
by a gear wheel 74, which is turned by a gear wheel 73, driven by an idler 21,
but, as above remarked, it is plain that many forms of gearing may be used without
affecting the principle of the machine.
In Figure 10 I have shown a means of supplying the jet pipe 43 with acid under
pressure, which apparatus can be used to advantage, and, as illustrated, the jet
pipe is supplied through a pipe 75, which connects with two acid tanks 76 and 77,
these being also connected by a valve-controlled pipe 78 so that the acid can be
forced from one to the other when desired.
These tanks are provided with drawing-off pipes 79 and connected by valve-
controlled pipes 80 with the acid pan 50. They also connect by means of suitable
valves with a pipe 81, which connects with a source of compressed air supply. It
will be seen then that by properly manipulating the valves the air may be forced
into either tank and the acid expelled through the pipe 75 and jet pipe 43, while
the accumulated acid in the pau 50 can be returned to either tank by opening the
valve of one of the pipes 80.
It will be clearly seen from the above description that the skins or pelts may be

page_text: entered one after another between the roller 26 and apron 27, and that they will
emerge on the carrier or belt 62 in a finished condition.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is :-
