PROVISIONAL SPECIFICATION.
A New or Improved Machine for Extracting the Hair from Skins.
We LINDLEY DAWN SHIRLEY CUFFLIN of 2 Beresford Road, Canonbury, North,
Engineer and GEORGE HUGHES of 12 Amersham Road, New Cross, S.E. Engineer
do hereby declare the nature of this invention to be as follows:-
Our Invention relates to a new or improved Machine for extracting the hair from
skins and has for its object to effect by machinery that which has hitherto been
accomplished by hand.
In carrying our Invention into practice we provide a suitable longitudinal frame at
one end of which is mounted a feeding roller over which travels a band or web of
leather, gutta percha or other suitable material furnished with a steel clip provided
with teeth or points. This clip.is concealed within the thickness of the web or band
and serving to fix thereon the skins whose hairs have to be extracted.
The said web or feeding band is caused to travel by a driving band between two
other feeding rollers mounted in suitable bearings and arranged so that the web may
also travel backwards if required.
The front end of the frame is provided with a roller of india rubber mounted on
suitable bearings of gun metal or other suitable material over which roller operates a
belicoidal nipping and pulling device furnished with four blunt blades and revolving
in a reverse direction to that of the india rubber roller.
The above rollers are all provided with cog wheels.at their extremities gearing with
one another in order to propel the web and rotate the nipping and pulling device
and the india rubber roller.
The above mentioned frame carrys on one side a motor pulley imparting a rotary
motion to the india rubber roller and a similar motion to the feeding band actuating
the web or band.
A curved knife is mounted upon the frame and serves to raise the hair of the skin
on its way to the nipping and pulling device.

COMPLETE SPECIFICATION.
A. New or Improved Machine for Extracting the Hair from Skins.
We LINDLEY DAWN SHIRLEY CUFFLIN, Engineer, and GEORGE HUGHES, Patent
Agent, both of 38 Chancery Lane, London W.C., 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 a new or improved machine for extracting or pulling the
hair from fur bearing skins, and has for its object to effect by machinery that which
has hitherto been accomplished by hand. The skin to be pulled is laid upon an
endless band.and held by a clip connected to the band the latter passes: round a small
roller which causes the hair to stand out as it passes round so that it may be caught
by the pulling device as hereafter described.
To enable our invention to be properly understood we will proceed to fully explain
the same with aid of the accompanying drawings.

page_text: Figure 3. a plan of the upper part of same, with lower pulleys omitted.
Figure 4. is a diagraphic view to illustrate more clearly the mechanism for pulling
or extracting the hair.
Figure 5. perspective view of one of the clips detached from belt.
Figure 6. cross section of the upper part of the frame and sliding bed taken on the
line X, Y, figure 1. A frame of machine having side plates B bolted thereto to form
a guide way for the plates C to enable them to rest edge ways upon the top of
frame these plates Care stayed by cross rods D. Between the plates C, travels an
endless band E, passing over a roller F, at one end of machine, and over. a small
roller G, at other end.. This band carries clips H, to hold the skin to enable it to
travel with the band. In front of roller G, is a fixed knife blade I, extending across
the machine to lift or hold out the hair on the skins while the same is passing round
the roller G, on the band E, to better enable the pulling device to take hold of the
hair over the roller G, is a second roller G; the journal ends of which are carried
by pivotted levers J, having a weight K to press down the same to hold the skin
firm while the pulling device is pulling out the hair.
The pulling device consists of a roller L, having preferably-four straight blunt
edge blades L, under which is an india rubber roller L2; the shafts of the two rollers
are geared together to run at the same surface speed and are so set that the blades L',
press into the surface of the roller L³, while revolving, and so catch and pull out any
hair that comes under the blades L' and over the roller L. The part C is arranged
to move upon the top of the frame A so that the end which carries the roller G,
may be set and held the necessary distance from the pulling device to suit the lengths
of hairs on the skins. This adjustment is effected by the regulating screw M, so held
in frame A as to be revolved by a crank handle M', the screw portion passing
through and engaging the cross stay M' between plates C. The tension of the
band E is provided for by the journal ends of the roller F, being carried in sliding
bearings held and adjusted by a screw N, held in frame. The rollers I, and L2 may
be geared together and are driven at a high rate of speed, by the pulleys O. and P,
and the roller F, by the pulleys Q, R, S, T, U, is the main driving shaft. The endless
band E, is preferred to be made of a double thickness of material to enable the clips H
when closed to be embedded flush with surface of band.
The knife I can be made adjustable as to position from the roller G, by washers or
other suitable known means.
It will be readily understood that instead of making the part C, adjustable to suit
the length of the hairs, the rollers L, L2, could be carried in an adjusting frame set
and held as described for part C.
Having now described and ascertained the nature of my invention, and in what
manner the same is to be performed, we declare that what we claim is.
1. A machine for pulling the hair from fur bearing skins, constructed and operating,
substantially as berein described and illustrated in the accompanying drawings.
2. In a machine for the purpose stated, the use of revolving blades and a suitable
roller for the blades to embed in when revolving, as and for the purpose described and
illustrated in the accompanying drawings.
3. In a machine for the purpose stated, the combination of an adjustable part C
carrying a travelling endless band having clips to hold the skin, and a knife blade to
raise the hair on the skin, as and for the purposes described and illustrated in the
accompanying drawings.
4. In a machine for the purpose stated, the combination with a travelling endless
band having clips to hold the skin, of the rollers G, and G¹, and pivotted weighted
lever J, to hold the skin firm while the hair is being pulled out.
