page_text: I, AMBROSE PATERSON, of 35 Great Dover Street, London, S.E. in the County
of Surrey, Furrier seek leave to amend the specification of Letters Patent,
No. 3429 of 1884, as shown in red ink in the copy of the original specification
hereunto annexed :-
My reasons for making this amendment are as follows:-The specification
describes and claims more than having regard to the state of knowledge at the
date of the Patent I was entitled to claim as my invention-The description and
drawings also require slight corrections to be made in order that the invention
may be more clearly explained.
AMBROSE PATERSON.

page_text: In the Matter of an Application by Ambrose Paterson for leave to amend the
Specification of his Invention Nº 3429 of 1884:
D
DECISION OF THE COMPTROLLER-GENERAL.
Having heard Mr Lawson of Counsel for the Applicant and Mr Clark as Agent
for the Opponent, I allow the Specification to be amended in the manner proposed,
with the modification agreed to at the Hearing: with the exception of the alteration
proposed to be made to the fifth claim.
The fifth claim is for a method of doing a certain thing by means of a certain
device previously claimed in combination with other parts of a Fur cutting
machine; but for which device no separate claim has been made. The proposed
alteration would claim the device in lieu of the method. In view therefore of
subsection 8 of section 18 of the Act I cannot allow the proposed amendments in
that claim.

page_text: Improvements in the Method of and Apparatus for Removing
66 Stagy" Hairs from Fur-seal and other Skins.
I, AMBROSE PATERSON of 35 Great Dover Street London S.E. in the county of
Surrey Furrier do hereby declare the nature of the said Invention for REMOVING
"STAGY HAIRS FROM FUR SEAL AND OTHER SKINS to be as follows:-
"
A certain class of skins such as Fur Seals, Otters, Beavers, & are greately
improved by the removal of the hairs that form the outer covering of the skin.
These hairs are removed in the process of dressing, or after the skin is dressed by
an operation known as "Pulling" or "Plucking." But by these processes only
those hairs which grow beyond the surface of the wool are removed, while those of
immature growth known technically as "Stagy hairs" are left in the skin thereby
greately disfiguring it.
My apparatus is designed with the object of removing these "Stagy hairs" and
is in the form of an attachment to an enlarged Fur Cutting machine.
It consists of an oscillating frame the movement of which is produced by a
crank and pulley driven from the main shaft of the Fur Cutting Machine. To the
Oscillating frame is attached two pairs of grooved rollers made to move inter-
mittently by pinnions working in a geared wheel, which is caused to revolve by an
endless screw and pinnion working in a suitable rack. The skin during the process
of removing the "Stagy hairs"” passes through the upper pair of rollers, thence
over the straight edge of the oscillating frame and through the lower pair of
rollers. These working simultaneously with the upper rollers cause the tension on
the skin to be uniform throughout. To secure the necessary tension while the
extremes are passing over the straight edge of the oscillating frame pieces of cloth
or other suitable material are attached to the ends of the skin thus leaving no part
unfinished. A rotary fan attached to, and driven by, the tension pulley of the Fur
Cutting Machine communicates by a pipe with a long narrow nozzle, suitably
placed near the edge of the oscillating frame. The current of air being of sufficient
force to blow down the more yielding wool leaving the stiff hairs projecting.
The skin being placed in the machine, the wool is held back on the top side of
the oscillating frame by a suitable guard rod with india rubber edge to give a firm
grip. During the forward movement of the oscillating frame the wool of that
portion of the skin over the edge of the frame is blown free from the hairs and is
held back by an under guard rod similar to the one on the upper side of the frame.
The "Stagy hairs" which are thus left_projecting are cut off on reaching the
knives of the Fur Cutting Machine. The oscillating frame then makes the
backward movement and in doing so brings the pinnion of the endless screw in
contact with the rack so moving the Skin forward over the edge of the frame. All
the foregoing movements are again brought into play and the operation is continued
until the whole skin is finished.

I, AMBROSE PATERSON, of 35 Great Dover Street London S.E. in the county
of Surrey Furrier do hereby declare the nature of my invention for IMPROVE
MENTS IN APPARATUS FOR REMOVING "STAGY HAIRS FROM FUR-SEAL AND
OTHER SKINS and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
A certain class of skins such as Fur Seals, Otters &e, are greately improved by
the removal of the hairs that grow beyond the surface of the wool and form the
outer covering of the skin. These hairs are generally removed, either in the process
of "dressing," or after the skin is "dressed" by an operation known as "pulling"
or "plucking" But by these processes only those hairs which extend beyond the
surface of the wool are removed: while those of immature growth and technically
termed "stagy hairs" are left in the skin and greately disfigure it. It has also
been proposed to remove such Stagy hairs by machines constructed for the purpose.
My improved apparatus is designed with the object of removing the "Stagy
hairs and is in the form of an attachment to an enlarged Fur cutting Machine, of
the ordinary construction and is designed with the object of removing the " Stagy
hairs in a more simple and rapid manner than by the machines hitherto in
use for the purpose. It will be obvious that the fur cutting machine must be of
sufficient width to receive the skins to be operated on.
The accompanying drawings fully illustrate the said invention.
Figure 1 represents a front view of the apparatus.
Figure 2 is a lateral or end view and shows the method of attaching the apparatus
by means of bolts a a to the frame of the Fur Cutting Machine, the latter being
indicated by dotted lines.
Figures 3, is-a-detached-view-of-the-endless-sorew-and-wheel 4, 5, and 6 repre-
sent enlarged views of certain details of my apparatus.
Figure 4 is a detached view of the rack and pinion for working the endless
serew.
Figures 5 and 6 represent different possitions of the guard rods during the
operation of removing the "Stagy hairs."
Similar letters of reference indicate corresponding parts.
The skin to be operated upon is first passed between the an upper pair of
grooved rollers B, thence over the straight edge of the an oscillating frame A,
and between the a lower pair of grooved rollers B¹. To secure the necessary
tension in the skin while the extremes thereof are passing over the straight edge
of the oscillating frame A, pieces of cloth or canvass of the requisite length are
attached to the ends of the skin. To facilitate the placing of the skin in the
apparatus the upper grooved rollere of each pair have has a squared heads b
projecting beyond the pinions b, to which a key can be attached and either pair
of rollers be made to move with rapidity-the geared wheel C being previously
removed by withdrawing the pin c. By this opperation also the skin is drawn
tightly over the straight edge of the oscillating frame A, and while it is held fast

page_text: the geared wheel C is replaced and the tension maintained until the skin is
finished.
On one side of the oscillating frame A the spindles of the grooved rollers B
and B¹ project beyond the bearings and have pinions b and b₁ attached. The
lower pinion b¹ of the upper pair of grooved rollers B, and the upper pinion b
of the lower pair of grooved rollers B₁ work in the geared wheel C. As the
oscillating frame A moves back from the cutters of the Fur Cutting Machine
the pinion c¹ on the endless screw C¹ comes in contact with the rack C³ causing
the endless screw C¹ to revolve shewn in detached views in figures 3 and 4. This
sets the geared wheel C and the pinions b and b¹ in motion. The skin stretched
over the straight edge of the oscillating frame A is thus moved forward a short
distance. As the oscillating frame A returns towards the cutters, the pinion c¹ is
prevented from moving by the pawl o², and the rack C2 is forced back by the
pinion c¹ and allows it to pass over. When the pinion c¹ has cleared the rack C
the spring forces it into possition again ready to engage the pinion c¹ as the
oscillating frame A moves back.
The apparatus is set in motion by the belt A¹ passing over the pulley A' on the
main shaft of the Fur Cutting Machine. The fly wheel A³ at the end of the shaft
carries a gut band a' which passes round the pulley at the end of the cylinder, to
which the cutters of the Fur Cutting Machine are attached, and round the pulley e
of the rotary fan E in place of the usual tension pulley of the Fur cutting Machine.
To the fan E is attached a pipe E' which is flattened and expands at E2 where it is
devided divided into chambers (as shown by the dotted lines) to equally distribute
the current of air, and terminates in a long narrow nozzle from which the air
issues. At the back of the Fur Cutting Machine is a double crank shaft F working
in suitable bearings f, screwed to the fiame of the Fur cutting Machine, and driven
by the pulley f¹ and gut band f¹ and pulley fƒ³ on the end of the main shaft of
the Fur Cutting Machine opposite to that on which the fly wheel A³ is fixed. To
the cranks f* which are near the ends of the crank shaft inside the bearings f-are
fitted the crank arms f³. And these being attached to the pins f* fixed to the
sides of the frame A. cause it to oscillate.
On the top of the oscillating frame A and near the straight edge is placed a
guard-rod D having the side adjacent to the skin covered with india rubber, that
it may press uniformly on the fur. This works in bearings d d but is prevented
from revolving by the edge coming in contact with the frame A. It is held in
possition by the set screws d¹ d¹ and protects the fur on the top side of the
oscillating frame from injury by the cutters of the Fur cutting Machine while
the "stagy hairs" are being cut off.
Figures 6 and 6 represent different positions of the guard-rods during the
operation of removing the "stagy hairs."
A slotted bearing d (a detached view of which is shown in figures 5 and 6) is
screwed to the Fur Cutting Machine near each end of the bed knife G, thereof and
carries the lower guard rod D¹. This is similar to the guard rod D but the ends
of the spindles d³ are squared so that they may work freely backwards and forwards
in the slotted bearings d³ without revolving. The ends of the spindles d³ project
beyond the slotted bearings and carry a small india rubber ring d in a groove cat
to receive it, and which prevents it slipping off. The india rubber ring d also
passes over a pin do fixed in the bearings d³ and thus acts as a spring and holds the
guard rod D¹ as shown in figure 5.
As the oscillating frame A moves forward and meets the lower guard rod D¹, the
india rubber rings d' draw the edge firmly on the under side of the straight edge
of the frame A, at the same time allowing it to move forward with the frame.
During the forward movement of the oscillating frame A, the part of the skin
immediately over the straight edge of the frame meets the current of air issuing
from the blowing apparatus. The yielding fur is blown downwards and
away from the "stagy hairs," and is caught by the under lower guard-rod D¹ and
held firmly against the lower side of the oscillating frame A. The rigid "stagy

page_text: hairs" thus left protruding are cut off on reaching the cutters of the Fur Cutting
Machine.
,
"
I am aware that in the machines hitherto in use for removing the "stagy-hairs
from skins a current of air has been used for blowing down the yielding fur as
described in the specifications of Letters Patent N 3226-1880 and N° 1102-1883
and I make no claim to the mere use of a current of air for such purpose.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
1. In an apparatus to be attached to an enlarged a Fur Cutting Machine for
removing "Stagy hairs from Seal skins, the combination of an oscillating frame
worked by a double crank shaft and crank arms, and the arrangement of grooved
rollers for passing the skin over the straight edge of the frame as described in the
foregoing specification.

נן
It consists of an oscillating frame the movement of which is produced by a
crank and pulley driven from the main shaft of the Fur Cutting Machine. To
the oscillating frame is attached two pairs of groved rollers made to move inter-
mittently by pinnions working in a geared wheel, which is caused to revolve by
an endless screw and pinnion working in a suitable rack. The skin during the
process of removing the "Stagy hairs passes through the upper pair of rollers,
thence over the straight edge of the oscillating frame and through the lower pair

The "Stagy hairs" which are thus left projecting are cut off on reaching the
knives of the Fur Cutting Machine. The oscillating frame then makes the
back ward movement and in doing so brings the pinnion of the endless screw in
contact with the rack so moving the Skin forward over the edge of the frame.
All the foregoing movements are again brought into play and the operation is
continued until the whole skin is finished.

I, AMBROSE PATERSON, of 35 Great Dover Street London S.E. in the county of
Surrey Furrier do hereby declare the nature of my invention for REMOVING
"STAGY HAIRS FROM FUR-SEAL AND OTHER SKINS and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
A certain class of skins such as Fur Seals, Otters &c, are greately improved by
the removal of the bairs that grow beyond the surface of the wool and form the
outer covering of the skin. These hairs are removed, either in the process of
dressing," or after the skin is "dressed" by an operation known as "pulling" or
"plucking" But by these processes only those hairs which extend beyond the
surface of the wool are removed: while those of immature growth and technically
termed "stagy hairs" are left in the skin and greately disfigure it.
My apparatus is designed with the object of removing the "stagy hairs and is in
the form of an attachment to an enlarged Fur cutting Machine.
The accompanying drawings fully illustrate the said invention.
Figure 1 represents a front view of the apparatus.
Figure 2 is a lateral or end view and shows the method of attaching the apparatus
by means of bolts a a to the frame of the Fur Cutting Machine, the latter being
indicated by dotted lines.
Figure 3 is a detached view of the endless screw and wheel.
Figure 4 is a detached view of the rack and pinion for working the endless
screw.
Figures 5 and 6 represent different possitions of the guard-rods during the
operation of removing the "stagy hairs."
Similar letters of reference indicate corresponding parts.
The skin to be operated upon is first passed between the upper pair of grooved
rollers B, thence over the straight edge of the oscillating frame A, and between the
lower pair of grooved rollers B¹. To secure the necessary tension while the
extremes are passing over the straight edge of the oscillating frame A, pieces of
cloth or canvass of requisite length are attached to the ends of the skin. To
facilitate placing the skin in the apparatus the upper grooved rollers of each pair
have squared heads projecting beyond the pinions b, to which a key can be
attached and either pair of rollers be made to move with rapidity-the geared
wheel C being previously removed by with drawing the pin c. By this opperation

page_text: also the skin is drawn tightly over the straight edge of the oscillating frame A,
and while it is held fast the geared wheel C is replaced and the tension maintained
until the skin is finished.
On one side of the oscillating frame A the spindles of the grooved rollers B
and B¹ project beyond the bearings and have pinions 6 and 1 attached. The
lower pinion b' of the upper pair of grooved rollers B, and the upper pinion b of
the lower pair of grooved rollers B₁ work in the geared wheel C. As the oscillating
frame A moves back from the cutters of the Fur cutting Machine, the pinion c¹
on the endless screw C¹ comes in contact with the rack C2 causing the endless
screw C¹ to revolve. This sets the geared wheel C and the pinions and b¹ in
motion. The skin stretched over the straight edge of the oscillating frame A is
thus moved forward a short distance. As the oscillating frame A returns towards
the cutters, the pinion c¹ is prevented from moving by the pawl c³, and the rack C'
is forced back by the pinion c¹ and allows it to pass over. When the pinion c¹ has
cleared the rack C the spring c³ forces it into possition again ready to engage the
pinion c¹ as the oscillating frame A moves back.
The apparatus is set in motion by the belt A¹ passing over the pulley A' on the
main shaft of the Fur Cutting Machine. The fly wheel A³ at the end of the shaft
carries a gut band a¹ which passes round the pulley at the end of the cylinder, to
which the cutters of the Fur Cutting Machine are attached, and round the pulley e
of the rotary fan E in place of the usual tension pulley of the Fur cutting Machine.
To the fan E is attached a pipe E which is flattened and expands at E' where it
is devided into chambers (as shown by the dotted lines) to equally distribute the
current of air, and terminates in a long narrow nozzle from which the air issues.
At the back of the Fur Cutting Machine is a double crank shaft F working in
suitable bearings f, screwed to the frame of the Fur cutting Machine, and driven
by the pulley and gut band f² and pulley f³ on the end of the main shaft of
Fur Cutting Machine opposite to that on which the fly wheel A³ is fixed. To the
cranks which are near the ends of the crank shaft inside the bearings f―are
fitted the crank arms f³. And these being attached to the pins f* fixed to the
sides of the frame A cause it to oscillate.
On the top of the oscillating frame A and near the straightedge is placed a
guard-rod D having the side adjacent to the skin covered with india rubber, that
it may press uniformly on the fur. This works in bearings dd but is prevented
from revolving by the edge coming in contact with the frame A. It is held in
possition by the set screws d² d¹ and protects the fur on the top side of the oscillating
fraine from injury by the cutters of the Fur cutting Machine while the "stagy
hairs" are being cut off.
A slotted bearing (a detached view of which is shown in figures 5 and 6) is
screwed to the Fur Cutting Machine near each end of the bed knife G, and carries
the lower guard rod.D'. This is similar to the guard rod D but the ends of the
spindles d³ are squared so that they may work freely backwards and forwards in
the slotted bearings d without revolving. The ends of the spindles & project
beyond the slotted bearings and carry a small india rubber ring d in a groove cut
to receive it, and which prevents it slipping off. The india rubber ring d' also
passes over a pin fixed in the bearings d and thus acts as a spring and holds the
guard rod D¹ as shown in figure 5.
As the oscillating frame A moves forward and meets the lower guard rod D¹, the
india rubber rings d' draw the edge firmly on the under side of the straight edge.
of the frame A, at the same time allowing it to move forward with the frame.
During the forward movement of the oscillating frame A, the part of the skin
immediately over the straight edge of the frame meets the current of air issuing
from the blowing apparatus. The yeilding fur is blown downwards and away
from the "stagy hairs," and is caught by the under guard-rod D' and held firmly
