WC, JAMES STANILAND STOCKS and BENJAMIN STOCKS, of Leeds, in
the County of York, Leather Dressers, and SAMUEL HUTCHINSON, of
the same Place, Manager, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY FOR SCOURING AND SHAVING HIDES,

-
This Invention relates to improvements in or additions to machinery
for which Letters Patent were granted to the said Samuel Hutchinson,
dated Aug. 10th, 1869, No. 2389, for striking out leather.

page_text: And these improvements consist in providing and employing, in
substitution of the spirally fluted roller therein shewn and described, a
spirally fluted knife or knives, that is, in having the knives or blades
made sharp so as to cut or shave hides or skins when passed through the
machine.
Also in providing and employing in substitution of these a cylindrical
brush to scour or brush hides or skins when passed through the said
machine, and which is constructed so that these several parts are readily
exchanged, thereby to adapt the machine for any of the aforesaid
purposes.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Staniland Stocks, Benjamin Stocks, and
Samuel Hutchinson in the Great Seal Patent Office on the 19th
September 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
STANLLAND STOCKS and BENJAMIN STOCKS, of Leeds, in the County of
York, Leather Dressers, and SAMUEL HUTCHINSON, of the same Place,
Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of March, in the year of
our Lord One thousand eight hundred and seventy, in the thirty-third
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said James Staniland Stocks, Benjamin Stocks, and
Samuel Hutchinson, Her special licence that we, the said James Staniland
Stocks, Benjamin Stocks, and Samuel Hutchinson, our executors, adminis-
trators, and assigns, or such others as we, the said James Staniland Stocks,
Benjamin Stocks, and Samuel Hutchinson, our executors, administrators,
and assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the term therein expressed, should
and lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN MACHINERY FOR SCOURING AND
SHAVING HIDES, SKINS, OR LEATHEв," upon the condition (amongst others)
that we, the said James Staniland Stocks, Benjamin Stocks, and Samuel
Hutchinson, our executors or administrators, by an instrument in writing

page_text: under our, or their, or one of their hands and seals, should particu-
larly describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed in
the Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said James Staniland Stocks, Benjamin
Stocks, and Samuel Hutchinson, do hereby declare the nature of our said
Invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement.
and accompanying Sheet of Drawings (that is to say) :-
This Invention relates to improvements in or additions to machinery
for which Letters Patent were granted to the said Samuel Hutchinson,
dated the Tenth day of August, One thousand eight hundred and sixty-
nine, Number 2389, for "striking out leather," and these improvements
consist in providing and employing, in substitution of or in connection
with the spirally fluted roller therein shewn and described, a spirally
fluted knife or knives, that is, in having the spiral knives or blades
made sharp so as to cut or shave hides or skins when passed through the
machine. Also in providing and employing in substitution of these a
cylindrical brush to scour, cleanse, or brush hides or skins when passed
through the said machine, and which is constructed so that these several
parts are readily exchanged, thereby to adapt the machine for any of the
aforesaid purposes.
In order that this Invention may be clearly understood reference is
given to an accompanying Sheet of Drawings.
DESCRIPTION OF THE DRAWINGS..
Fig. 1 is the front elevation of a machine constructed in accordance
with the said Invention; Fig. 2 is an end elevation; Fig. 3 is a plan;
and Fig. 4 is a vertical cross section of the same.
The part marked with the letter A is the spirally fluted knife or
knives consisting of a series of spirally formed knives or blades A', fixed
upon a series of bosses A², fixed on a shaft A³ (or they may be fixed on a
roller), the spirals of the said knives running in opposite directions from
the middle thereof. The outer edges of these knives are made sharp
when required for cutting or shaving, but may be rounded or not made
sharp if required for scouring. The part marked with the letter B is a
spirally fluted roller used for striking out or straightening the hides or

page_text: skins, and C is a cylindrical table or bed for the hides, skins, or leather to
be fixed and held upon and brought under operations of either or botli the
spiral roller or the spiral knives. This cylinder is formed with a slit or
gap C¹ longitudinally thereof, which is provided with a moveable jaw or
clamp D, carried by toothed segments E, which are operated by toothed
wheels F so that when a skin or hide G is placed in the gap the jaw D
can be pressed forward so as to nip and hold it against one side of the
gap, which is prepared suitably for that purpose. This shaft A³ with
the spiral knives is mounted in suitable framework H, which is similar
to that described in the Specification of Samuel Hutchinson's Patent
referred to, and in substitution of the spiral roller therein described; also
rotary motion is given to it by one of the pair of driving pullies I. It
is raised out of and placed in contact with or the distance regulated
from the cylindrical table (when required) by means of the screws J,
cross shaft K, and the gear wheels L, and motion is communicated from
this shaft to the cylinder by means of spindle M, worm and worm
wheel N, in the same manner as shewn and described in the said
Specification of S.
Hutchinson's Patent, herein-before referred to. The
spiral fluted roller here shewn is same as the one shewn in the aforesaid
Specification, and is mounted in arms P hinged to the framing; the said
arms being connected by a cross rail P¹, to which is attached a rack S
in which gears a toothed wheel T fixed on a shaft supported by arms U
projecting from the framing, by means of which the said spirally fluted
roller is raised out of and lowered into contact with the cylinder when
required. Motion is given to this roller by gear wheel V from a pinion
and the gear wheel V¹ fixed on the knife shaft.
The method of using this machine is as follows:-The cylinder being
turned with its gap to the front a hide or skin is fixed thereon by the
jaw, then the cylinder is turned so as to draw the hide under the roller
and knives as shewn, the former of which strikes out or straightens it
by reason of the divergency from middle of the spiral flutes, then tho
spiral knives operate upon it, cutting or shaving it to any desirable
extent or thickness, according as the said knives are set nearer to or
further from the cylindrical table, and which operation is continued until
the hide or skin has completely passed the knives. This machine may
be used for either fleshing or scudding by having the knives blunt or not
sharp and for scouring or cleansing by substituting a cylindrical brush
instead of the spiral knived roller, as shewn at Fig. 5. Thus one

page_text: machine may be constructed according to our Invention so as to be
readily adapted to the several purposes herein set forth.
In witness whereof, we, the said James Staniland Stocks, Benjamin
Stocks, and Samuel Hutchinson, have hereunto set our hands
and scals, this Fifteenth day of September, in the year of our
Lord One thousand eight hundred and seventy.
