page_text: LETTERS PATENT to James Staniland Stocks and Benjamin Stocks both of
Leeds in the County of York for an invention of "IMPROVEMENTS IN
MACHINERY EMPLOYED IN THE PREPARATION OF HIDES SKINS AND LEATHER
"
PROVISIONAL SPECIFICATION left by the said James Staniland Stocks &
Benjamin Stocks at the Office of the Commissioners of Patents on the
10th May 1882.
'
JAMES STANILAND STOCKS and BENJAMIN STOCKS both of Leeds in the County
of York "IMPROVEMENTS IN MACHINERY EMPLOYED IN THE PREPARATION OF
HIDES, SKINS AND LEATHER
Our Invention has reference to machinery employed for unhairing scudding and
fleshing hides or skius, also for striking or setting out, shaving scouring and
brushing leather, and is applicable to such of those machines as are provided with
drums, cylinders, or beams for supporting or carrying the material, during the
various operations above mentioned.
Hitherto what is known as a slip rod has been used for retaining the material
in position on the drums cylinders or beams. When this is used the whole of the
material to be operated upon is suspended or exposed and has a tendency to fall
away during the rotary motion of the drum cylinder or beam causing in some
cases great inconvenience to the operator.
Now in our arrangement we provide a hollow drum, cylinder or beam having a
slit along its full length, through this we pass into the interior any required
amount of the material, leaving on the surface of the hollow drum, cylinder or
beam only as much of the material as is necessary to be operated upon at one
time. Within the hollow drum, cylinder or beam is provided a pressure bar or
appliance whereby the material is held in a fixed position during the various
operations. The required pressure or nip is imparted to the bar by ordinary
mechanical means. After the part on the surface has been operated upon, the
material is released and reversed, that is to say, the material within the hollow
drum, cylinder or beam is withdrawn and the part that has been operated upon is
placed in the interior of the hollow drum cylinder or beam, after which the
material is again held in position by the bar for continuing the operations.

Our Invention has reference to machinery employed for unhairing, scudding, and
fleshing hides or skins, also for striking or setting out, shaving, scouring, and
brushing leather and is applicable to such of those machines as are provided with
drums cylinders, or beams for supporting or carrying the material during the
various operations above mentioned. Hitherto what is known as a slip rod has
been used for retaining the material in position on the drums, cylinders, or beams.
When this is used the whole of the material to be operated upon is suspended or
exposed and has a tendency to fall away during the rotary motion of the drum
cylinder or beam causing in some cases great inconvenience to the operator
Now in our arrangement we provide a hollow drum cylinder or beam having a
slit along its full length, through this we pass into the interior any required
amount of the material leaving on the surface of the hollow drum, cylinder, or
beam, only as much of the material as is necessary to be operated upon at one
time. Within the hollow drum cylinder or beam is provided a pressure bar or
appliance whereby the material is held in a fixed position during the various
operations. The required pressure or nip is imparted to the bar by ordinary
mechanical means. After the part on the surface has been operated upon the
material is released and reversed that is to say the material within the hollow
drum cylinder or beam is withdrawn and the part that has been operated upon is
placed in the interior of the hollow drum cylinder or beam, after which the
material is again held in position by the bar for continuing the operations
And in order that our Invention may be the more completely understood
reference is given to the accompanying Sheets of drawings and to the letters and
monka thorean
Fig 1 is a Front Elevation and Fig 2 an End Elevation of the Machine. Fig 3
is a Transverse Section of the drum cylinder or beam and Fig 4 is an End
Elevation of the saine.
aa shew the standards or supports between which is mounted in adjustable
bearings bb the rotating spiral cutter or scraper c all of which are of ordinary
construction
Between the standards or supports a a is also provided a drum cylinder or
beam & mounted upon the shaft e supported in bearings of ordinary construction
in the standards or supports a a. This drum cylinder or beam & is used for
carrying the material during the various operations of unhairing scudding and
fleshing hides or skins also for striking or setting out shaving scouring, and
brushing leather
Instead of using what is known as the slip rod which has hitherto been used
for retaining the material in position on the drum cylinder or beam we make the
drum cylinder or beam & hollow having a longitudinal slit or opening f. Through
this we pass into the interior any required amount of the material leaving on the
surface of the drum cylinder or beam d only as much of the material as is necessary
or convenient to be operated upon at one time. Within the hollow drum cylinder

page_text: or beam & is provided a pressure bar g also an adjustable block h between these
the material is held in a fixed position during the various operations.
The required pressure or nip is imparted to the bar g by the attendant through
the hand lever i longitudinal rod k, levers l, and links m. The hand lever i is
retained in any desired position to suit the nip or thickness of the material to be
operated upon by the flat spring n.
Into the circular slot holes o are passed the ends of the pressure bar g provided
with slide blocks p, such slot holes serving as guides for the pressure bar g. The
pressure bar g is withdrawn from nipping the material by moving the hand lever i
in the opposite direction to that required for bringing it up to its work The
block h may be adjusted by means of the inclines q attached to the longitudinal
rod r screwed at each end and provided with adjusting nuts s; (The inclines q
being in contact with corresponding inclines t on the block h) by moving the
inclines backwards or forwards by means of the nuts 8 on the screwed ends of
the rod, the block h may be raised or lowered at pleasure and afterwards retained
in any desired position by the screws or bolts u. Any other equivalent means
may be employed for adjusting this block h

We by preference employ the springs v for imparting the required pressure to
the rotating spiral cutter or scraper c such pressure being varied through the
medium of the vertical adjusting screws w these being actuated by ordinary means
The object of the above mentioned springs vis to permit of the spiral cutter
or scraper c adapting itself to the various irregularities in the material operated
upon.
The means of imparting motion to the machine, and other parts of the machine
not described may be of ordinary construction
Having now described the nature of our said Invention and shewn by drawing
how the same may be carried into practice, we would have it understood that we
do not limit ourselves to the precise details or configuration of the parts we have
described and shewn as the same may be varied or modified without departing
from the nature of our said Invention, what we do claim are :-
The arrangement construction and application of the hollow drum cylinder or
beam d having in combination the pressure bar g and parts connected therewith
for retaining the material in position substantially as and for the purposes herein
set forth.
In Witness whereof we the said James Staniland Stocks and Benjamin Stocks
have hereunto set our hands and seals this thirty first day of October in
the year of Our Lord One thousand eight hundred and eighty two.
