PROVISIONAL SPECIFICATION left by the said Samuel Hutchinson at
the Office of the Commissioners of Patents, with his Petition, on
the 10th August 1869.
I, SAMUEL HUTCHINSON, of Leeds, in the County of York, Leather
Dresser, do hereby declare the nature of the said Invention for "İM-
PROVEMENTS IN MACHINERY OR APPARATUS FOR STRIKING-OUT' LEATHER," to
be as follows:-
This Invention relates to means of effecting what is technically known
as "striking-out" or stretching and straightening skins in the process.
of leather dressing, and the improvements consist in the combination of
a plain even surfaced roller having a recess therein and a slip-rod or
fastener to hold a skin when placed on the said roller with a spirally
fluted roller, the spirals of which run in opposite directions from the
middle thereof.. These rollers are caused to rotate at different surface.

page_text: upon it to strik out, stretch, or expand and straighten the same, for
which purpose it is run at a greater surface speed than the plain one.
The said rollers are mounted in suitable framework, and may be driven
by gearing pullies and straps or equivalent means from any convenient
source of motive power or by manual power.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Hutchinson in the Great Seal Patent Office
on the 10th February 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
HUTCHINSON, of Leeds, in the County of York, Leather Dresser, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of August, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Samuel Hutchinson, Her special license
that I, the said Samuel Hutchinson, my executors, administrators, and
assigns, or such others as I, the said Samuel Hutchinson, my 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
OR APPARATUS FOR STRIKING-OUT LEATHER," upon the condition (amongst
others) that I, the said Samuel Hutchinson, my executors or adminis-
trators, by an instrument in writing under my, or their, or one of
their hands and seals, should particularly 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 immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said Samuel Hutchinson, do hereby
declare the nature of my 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):-

page_text: This Invention relates to means of effecting what is technically known
as striking-out or stretching and straightening skins in the process of
leather dressing, and the improvements consist in the combination of
a plane even surfaced roller having a recess therein and a slip-rod and
fastener to hold a skin when placed on the said roller with a spirally
fluted roller, the spirals of which run in opposite directions from the
middle thereof. These rollers are caused to rotate at different surface
speeds, the plane one to carry the skin and the fluted one to operate upon
it to strike out, stretch, or expand and straighten the same, for which
purpose it is run at a greater surface speed than the plane one. The
said rollers are mounted in suitable framework, and may be driven by
gearing pullies and straps or equivalent means from any convenient
source of motive power or by manual power.
This Invention will be readily understood by reference to the accom-
panying Sheet of Drawings, wherein Fig. 1 is the front elevation, and
Fig. 2 is an end elevation of a machine constructed in accordance
therewith.
A is the plane surfaced roller having a recess in which is a slip-rod a,
held by a screw bolt a¹. This roller is mounted in stationary bearings
of the frame ends B, which are held together by the tie rods B' secured
by screw nuts; C is the spirally fluted roller mounted in bearings
capable of being moved up or down in the said end frames so that its
surface may be adjusted or set nearer to or further from the surface of
the plane roller as required, which adjustment is effected by means of
the cross shaft D and the winch handle D', bevél wheels D2 and D³
connecting same with the screw pins D and D³ attached to the bearings
of the said roller. On one end of this fluted roller are the driving
pullies E and E', and on the other end is a worm F in gear with a
wheel F¹ loose on an upright shaft G on which is fixed a worm G' in
gear with a wheel H fixed on the end of the shaft of the roller A. On
the top of the shaft G is a slideable clutch I moveable on a feather in
the said shaft by the handle J which is hinged on a pillar K so as to
place it in or out of gear with another clutch on the wheel F", whereby
when in gear a slow motion is communicated from the roller C to the
roller A.
The method of using this machine is as follows:-A bolster of india-
rubber and another of leather are first fixed each by one edge in the
recess of the roller A and are loose at the other edges, so that as the

page_text: said roller is turned they become wound tight on the said roller, and the
india-rubber being elastic will yield to the inequalities in the substance
of the skin when placed thereon to be operated by the fluted roller.
It will now be readily seen that if a skin be placed with its rigg or
about its middle from neck to butt or acrosswise thereof from belly to
belly under the slip rod in the recess and the rod secured by the screw
bolt so as to hold the said skin thereon, and on motion being given to the
rollers in the proper direction the skin will pass in betwixt them, when
the spiral flutings of the roller C diverging from the middle will "strike
out" or stretch the said skin on one side of the rod during its passago
and thereby straighten or make it even ready for the process of shaving
or any other purpose for which it may be required. The said skin is
then turned or changed that the other side may be operated upon in liko
manner.
Having thus described the nature of the said Invention, and shewn
by Drawings how the same is performed or carried into practice, I would
have it understood that I do not confine myself to the precise details in
the construction or arrangement of the machine as herein described and
shewn in the Drawings, as various modifications may be made therein;
but what I claim as my Invention is, the combination of a plane roller
with a spirally fluted roller arranged and used in manner and for purposes
substantially as shewn and described.
In witness whereof, I, the said Samuel Hutchinson, have hereunto
set my hand and seal, this Eighth day of February, in the
year of our Lord One thousand eight hundred and seventy.
Signed, sealed, and delivered by
the within-named Samuel
Hutchinson, in the presence
of
W*. TASKER,
Patent Agent,
SAMUEL HUTCHINSON. (L.S.)
