cessors, give and grant unto us, the said John Cockill, Thomas Shaw,
John Keir, and John Craven, Her special licence that we, the
said John Cockill, Thomas Shaw, John Keir, and John Craven,
our exccutors, administrators, and assigns, or such others as the said
John Cockill, Thomas Shaw, John Keir, and John Craven, 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 OR APPARATUS FOR SCOURING AND SETTING HIDES,
BUTTS, OR OTHER KINDS OF LEATHER," upon the condition (amongst others)
that we, the said John Cockill, Thomas Shaw, John Keir, and John
Craven, our executors or administrators, by an instrument in writing
under our, 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 we, the said John Cockill, Thomas Shaw, John
Keir, and John Craven, 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 state-
ment and accompanying Sheets of Drawings (that is to say) :-
This Invention consists in the employment of a drum or cylinder
on the periphery of which are fixed a series of knives or scrapers which
are curved across the surface by preference in form of a parabola, and
alternately with these knives are a series of brushes also fixed on the
said cylinder. This cylinder is fixed on a shaft mounted so as to be
capable of rotating on suitable framework.
Also a rotating roller covered with india-rubber or other flexible
material is mounted on a swing frame underneath the said cylinder,
this frame being hinged to the former frame and so constructed as

page_text: that any suitable amount of weight may be applied to press the roller
against the cylinder, and a foot lever is also applied by means of which
the attendant can readily remove the roller from contact with the
cylinder.
Also a moveable table is supported upon friction rollers carried on 5
the framework, its upper surface being level (or thereabout) with the
point of contact or conjunction of the cylinder and roller, and having
a slot hole or aperture therein for the upper part of the roller to pass
through and to allow for the table to be moved as required.
The table is provided with either an eccentric shaft or a bar and 1
screws or other suitable contrivance for readily fixing a hide thereon,
so as to be thereby drawn in betwixt the roller and the cylinder, and
operated upon by the knives, or scrapers, and brushes, which straighten
and scour the same whilst passing.
In order that the Invention may be fully understood, reference is 1
given to the accompanying Sheet of Drawings of a machine constructed
in accordance therewith.
Fig. 1 is a sectional elevation; Fig. 2 is a front elevation; and Fig. 3
is a plan of the table. Figs. 4, 5, and 6, are details.
A is the drum or cylinder fixed on a shaft B mounted in bearings on 2
suitable framework C, and capable of having rotary motion given it by
means of a strap D operating on the driving pulleys D' and D³. On
this are fixed a series of knives or scrapers E, and also a series of
brushes F (shewn in the details Figs. 4 and 5, which are half full size.)
G is the roller covered with india-rubber or other flexible material 2
fixed on a shaft which is mounted in a swing frame H supported and
hinged on stands I and J, fixed to the general framework. A box K is
fixed to the swing frame H. to receive weights or heavy material for
applying pressure or pressing the roller G against the drum; and L is a
treadle or foot lever also fixed to the frame H for enabling the attendant 3
to take off the pressure or remove the roller from contact with the
drum. Rotary motion is given to this roller by spur gear wheels M
and N, shaft O, pulleys and strap P from the shaft B of the cylinder.
Qis the moveable table supported on friction rollers R, this table
having a slot hole or aperture to receive or allow the roller G to pass 3
through it (see Fig. 3), which slot hole is fitted or filled up by a
board S fixed to the frame, the top surface being even with the table

page_text: and so that the table will move or slide on or against the said board
which thereby forms a guide; also in the front end of the slot hole is a
lattice sheet T, one end being attached to the table at T, and the said
sheet after passing over the rollers U (which is supported in brackets V
affixed to the stands I' and J¹) is wound upon a roller W, the other
end being fixed thereto, and on the shaft of which is fixed a roller W'
around which a cord W2 is wound and the end fixed thereto, the said
cord passing over and around one part of a double scroll pulley ✗
mounted on a stud fixed to the framework, and attached to the other
part of the said scroll is another cord Y, which passes around a pulley Y¹
at the end of the table, thence to the bracket I¹ to which it is attached,
when as the table is drawn backwards and forwards motion will be given
to the roller W to wind on or off the lattice sheet as required. Z is an
eccentric shaft attached to the table by brackets or bearings (see Fig. 6),
which is full size, by means of which shaft the hides are readily fixed
to the table to be operated upon by the knives, or scrapers, and brushes.
It will now be observed that when a hide is laid on the table and
fixed thereto by the said eccentric shaft (or other means of fixing), and
the table moved back with the hide betwixt the drum A and the
roller G (the latter being pressed by the attendant acting on the lever L
out of contact for the purpose), and liberated when the table is drawn
forward and the knives, or scrapers, and brushes, operate upon the hide
whereby they become scoured or set. As the table is drawn forward
by the attendant the lattice sheet is unwound from the roller, and forms
a continuous filling up of the slot hole in the table, which serves as a
bed or support to the hide.
Having thus described the nature of the said Invention, and, the
manner in which the same is to be performed or carried into practical
operation, we would have it understood that we do not claim the whole
of the parts or apparatus herein described and shewn, but what we do
claim as of our Invention is,―
Firstly. The employment of a drum having knives or scrapers of the
form shewn and with brushes alternately between them, in manner
described and illustrated.
Secondly. The rotating roller covered with india-rubber or other
flexible material hinged and weighted so as to constitute a self-acting
flexible bed to the drum.

page_text: Thirdly. The moveable table having a slot hole for the roller G to
pass through, and parts in connection therewith, and for fixing the hide
thereto, in manner and for purposes substantially as shewn and de-
scribed.
In witness whereof, I, the said John Keir, for and on behalf of 5
myself and the said John Cockill, Thomas Shaw, and John
Craven, have hereunto set my hand and seal, this Sixteenth
day of July, in the year of our Lord One thousand eight
hundred and seventy-two.
