page_text: LETTERS PATENT to John William Janson, of No. 52, Saint Mary Axe, in
the City of London, Merchant, for an Invention of "IMPROVEMENTS IN
MACHINERY FOR UNHAIRING, FLESHING, PARING, SHAVING, AND SETTING
HIDES, SKINS, OR PELTS."
PROVISIONAL SPECIFICATION left by the said John William Janson at
the Office of the Commissioners of Patents on the 23rd September 1881.
JOHN WILLIAM JANSON, of No. 52, St. Mary Axe, in the City of London,
Merchant. "IMPROVEMENTS IN MACHINERY FOR UNHAIRING, FLESHING, PARING,
SHAVING, AND SETTING HIDES, SKINS, OR PELTS."
This Invention relates to improvements particularly applicable to the machino
known as the "Molinier machine," whereby the skin, hide, or pelt is worked upon
both sides simultaneously.
For this purpose I propose to place a second knife cylinder immediately under
the ordinary india rubber roller, and another india rubber or elastic rollor beneath
the ordinary, or what may be now termed the upper knife cylinder. I so arrange
this second india rubber roller that it may be moved horizontally by the aid of a
lever or otherwise up to the second knife cylinder when required.
The skin or hido first presented between the top knife cylinder and the ordinary
elastic roller passes over this latter, it is then caught between the second olastic
roller and the second knife cylinder, the skin is then drawn out by the clips in tho
ordinary, and thus passing between two sets of cylinders and rollers is treated
simultaneously on both sides.
The knives on the cylinders will be adapted in the usual way for the purpose
required.

page_text: It will be seen that whereas the roll D is capable of a vertical motion, the lower
or second elastic roll F is free to move in a horizontal direction, being hung upon
the two arms or levers Q, Q, working upon pins secured in the end standards A, A.
Two rods R, R, serve to connect these arms Q, Q, to two short levers T, T, secured
upon a cross shaft S arranged immediately in front of the machine. Motion being
imparted to this shaft S by means of the hand lever U working the quadrant V,
as shown.
By this arrangement the roll F can readily be drawn forward and so brought
into action with tho lower knife cylinder E when required.
By lowering the top roll D to the position shown in Figure 4, the band & is drawn
tight and the roll D caused to revolve carrying with it the skin or hide x which
enters and falls down between the rolls. Upon raising the roll D by means of the
treadle I the band d is at once slackened and the roll D is free to revolve with
the cylinder C.
The drawbar or clips G is connected by a rope passing around a guide pulley
secured at the outer end of tho guide bars H (not shown in Drawing) with the
ropo wheels Z, Z, by which means it is caused to travel in an outward direction,
carrying with it the skin or hide to be operated upon.
The operation is as follows :-
In entering the skin or hide into the machine, the workman first presents it
between the top knife cylindor C and the roll D, the reverse rotary motion of which
carries it down to the knife cylinder E and roll F, these being in the relative
position shown Figure 4. The skin having thus been entered, the clips or draw-
bar G is in the position shown, Figure 4.
The workman now puts roll F into action with cylinder E by moving the
lever U, and then by pulling the clips G towards him takes a little hair from the
skin by the lower knife cylinder E (say for about 8 or 9 inches, or the distance
between the two rolls D and F), he then allows the skin to run back again and
placing his foot upon the treadle I lifts the roll D when the band b becomes slack
(as shown, Figure 5) and the roll D is free to turn with the knife cylinder C.
The workman holding the skin in the clips G pulls it towards him until with-
drawn from the machine, and during this movement each knife cylinder operates
simultaneously upon a different side of the skin.
It will be understood that the skin is not worked upon at all in its passage
down to the lower knife cylinder, but that as it is withdrawn it is operated upon
on different sides by the cylinders C and E working simultaneously.
The hair and fleshings I separate by a shield over which the fleshings are
carried, or in any suitable manner.
The cylinders will be furnished with knives of various kinds according to the
requirements of the particular operation to be performed upon the skin, and each
cylinder will not necessarily carry at the same time the same kind of knives
as the two cylinders while working simultaneously may be performing different
operations.
Having now described and ascertained the nature of my said Invention and in
what manner the same is or may bo performed, I would have it understood that
I do not limit myself to the exact details of construction herein set forth and
shown in the annexed Drawings, as such may be varied whilo retaining the
essential characteristics of my Invention, nor to the use of any particular
material for the elastic rolls or any other part of my machine, and that
What I claim as of my Invention, and as secured to me by the herein before in
part recited Letters Patent is,―
Firstly. In a machine for unhairing, fleshing, paring, shaving, and setting hides,
skins or pelts, the knife cylinder E and roller F, in combination with the knifo
cylinder C and roller D, and arranged to operate substantially as and for tho
purposes hereinbefore specified.

page_text: Secondly. The machine hereinbefore described and shown on the Drawing
hereunto annexed, as and for the purposes specified.
In witness whereof, I, the said John William Janson, have hereunto set my
hand and seal, this Twenty third day of March, in the year of our Lord
One thousand oight hundred and eighty two.
