Improvements in Apparatus for Removing the Hair from Skins.
A communication from abroad by FRÉDÉRIC GUILLAUME HERMANN, of 11, Rue
Barbette, Paris, in the Republic of France, Engineer.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E. of the Agency for Foreign
Patent Solicitors 6 Lord Street, Liverpool, and 6 Bank Street, Manchester, both in
the County of Lancaster, and 333 High Holborn in the County of Middlesex, Civil
Engineer, 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:-
The machine, which is the object of the present application for patent, possesses
several distinctive characteristics which are hereinbelow described.
The drawings annexed to this specification represent, in detail, this machine, an
show the principal parts, the mode of action of which is described hereinafter
Figure 1 is a side view of the machine in action.
Figure 2 is a side view of the machine when at rest.
Figure 3 is a section on the line X X, of Figure 1, looking from the front.
Figure 4 is a plan view.
Figure 5 is a plan view of the movable cross piece.
Figure 6 represents the winding on drumm B, the guide drum D and the saw in
detail.
The machine is composed of two lateral frames A A' having cross pieces QQ¹.
These frames support a drum B on which the skin to be treated is wound by means
of the rotation of the said drum.
This winding on takes place by means of the claws C clasping the skin which
passes from the guide roller D, the skin being in the first place, on the table V.
A cylindrical brush F constantly raises the hair on the skin, which is drawn forward
and subjected to the action of the band saw S'.
A similar
This saw passes over two drums E E set in action by a belt T running in the
groove T and over guide pulleys II' and from there on to the driving pulley.
These pulleys are supported by brackets H fixed on the frame A.
bracket H supports the driving axle of the pulley J intended, with the intermediary
help of the pulleys K. L, to cause the rotation of the drum Band of the brush F.
A connected group of levers O, P, R, S, can, under the action of handles M M'
actuating an axle N to which they are connected, cause the saw and brush to be raised
together as is shown in Figure 2. For this purpose the drums E E¹ of the saw
(Figure 6) are fitted together with the axle of the brush on a movable cross piece Q¹
(Figure 5).
A slide or groove o allows the distance between the drums to be regulated and
consequently the saw to be held taut.
The saw used is a blade of steel without teeth, sharpened to a bevel, its lower part
only being in contact with the skin.
The various parts thus described and shown in the annexed Figures are set in
ction and work in the following manner :-
The driving belts being put in position, the drums revolve in the direction of the
rrows; the brush, as shown, in an inverse direction to the others in order to con-
tantly raise the hair under the saw.
The skin being attached by means of the holder C, spread across the length of the
rum B, first passes between the brush F and the said drum B.
gear.
The saw is then pressed down (Figures 6 and 1) and the belts set in
The saw then shears off the hair which the brush constantly raises, the said
air falls into the gutter G, and from there it may be removed to any required
lace.

page_text: The winding of the shaven skin then takes place on the drum B until all the hair
is removed.
This done, the parts of the apparatus shown in Figure 6 are raised by means
of the handles M M³, (Figure 2) the skin is unwound from the drum, and the
operation recommences.
It must be understood that the shape, dimensions and connections of the various
parts may be varied without departing from the spirit of this invention.
Having now particularly described and ascertained the nature of the said inven-
tion, 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 :-
1. In an apparatus for removing hair from skins, the combination of a drum
adapted to pull the skin through the machine, a rotating brush which raises the hair
upon said skin, and a continuous band saw or knife which cuts or saws it off, the said
brush and saw being pivotally mounted in such a manner as to be capable of
being lifted away from the track of the skin when desired, substantially as described
and shown.
2. In an apparatus such as described a winding drum B having claws or other
attaching devices adapted to grip the skin and keep it stretched while being shaved,
substantially as described.
