page_text: LETTERS PATENT to David Stott, of the Firm of John Whiteley &
Son, of Firth House Mills, Stainland, in the County of York, Paper
Manufacturers, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE
OF RINGS FROM PAPER, MILLBOARD, OR PASTEBOARD, APPLICABLE FOR STEAM OR
OTHER PIPE JOINTS, BOBBIN ENDS, OR OTHER PURPOSES, AND IN THE MEANS
OB APPARATUS EMPLOYED THEREIN, WHICH ARE ALSO APPLICABLE TO THE MANU-
FACTURE OF RINGS FROM OTHER FLEXIBLE SUBSTANCES."
Sealed the 10th October 1862, and dated the 16th April 1862.
PROVISIONAL SPECIFICATION left by the said David Stott at the Office
of the Commissioners of Patents, with his Petition, on the 16th April
1862.
I, DAVID STOTT, of the Firm of John Whiteley & Son, of Firth House
Mills, Stainland, in the County of York, Paper Manufacturers, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE MANU
PACTURE OF RINGS FROM PAPER, MILLBOARD, OR PASTEBOARD, APPLICABLE POR STEAM.
OE OTHER PIPE JOINTS, BOBBIN ENDS, OR OTHER PURPOSES, AND IN THE MEANS OR
APPARATUS EMPLOYED THEREIN, WHICH ARE ALSO APPLICABLE TO THE MANUFACTURE
OF RINGS FROM OTHER FLEXIBLE SUBSTANCES," to be as follows:-
This Invention relates chiefly to the formation of rings or washers of paper
or millboard, used for placing betwixt the flanges of steam pipes or other
pipes for making the joints tight, or for securing the proper jointing thereof,
and which rings have heretofore been formed by describing or marking them

page_text: on a sheet of paper with compasses to the size required, and then cutting them
out with chisel or gouge and mallet, which is both a tedious and wasteful
process, nor can they be formed with that regularity of outline and size
desirable.
Now, my improvements consist in stamping or cutting out various sizes of
rings from one sheet concentrically to each other by means of a series of
circular or annular stamps, punches, or cutting instruments applied or
attached to any stamping, punching, or pressing machine of sufficient strength
and actuating or motive power; by this means paper rings can be produced
with facility and regularity of size, and also with less waste of material.
Rings thus manufactured may be used for bobbin ends, which will be more
durable than wood, as they will not break with falling, and such rings may be
applied to other useful purposes. Cutting instruments of this construction
and arrangement may also be applied or used for cutting sheet lead, gutta
percha, or other flexible substances into rings.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said David Stott in the Great Seal Patent Office on the 16th
October 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DAVID
STOTT, of the Firm of John Whiteley and Son, of Firth House Mills, Stain-
land, in the County of York, Paper Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of April, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said David Stott, Her special license that I, the said David Stott, my
executors, administrators, and assigns, or such others as I, the said David
Stott, 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
THE MANUFACTURE OF RINGS FROM PAPER, MILLBOARD, OR PASTEBOARD, APPLICABLE
FOR STEAM OR OTHER PIPE JOINTS, BOBBIN ENDS, OR OTHER PURPOSES, AND IN THE

page_text: MEANS OR APPARATUS EMPLOYED THEREIN, WHICH ARE ALSO APPLICABLE TO THE
MANUFACTURE OF RINGS FROM OTHER FLEXIBLE SUBSTANCES," upon the condition
(amongst others) that I, the said David Stott, my executors or administrators,
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 Inven-
tion, 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 David Stott, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):-
This Invention relates chiefly to the formation of rings or washers of paper
or millboard, used for placing betwixt the flanges of steam pipes or other
pipes for making the joints tight, or for securing the proper jointing thereof,
and which rings have heretofore been formed by describing or marking them
on a sheet of paper with compasses to the size required, and then cutting
them out with chissel or gouge and mallet, which is both a tedious anl
wasteful process, nor can they be formed with that regularity of outline and
size desirable.
Now, my improvements consist in stamping or cutting out various sizes of
rings from one sheet concentrically to each other by means of a series of
circular or annular stamps, punches, or cutting instruments applied or,
attached to any stamping, punching, or pressing machine of sufficient strength,
and actuating a motive power; by this means paper rings can be produced
with facility and regularity of size, and also with less waste of material. Rings
thus manufactured may be used for bobbin ends, which will be more durable
than wood, as they will not break with falling; and such rings may be applied
to other useful purposes. Cutting instruments of this construction and
arrangement may also be applied or used for cutting sheet lead, gutta percha,
or other flexible substances into rings.
In order that the Invention may be clearly understood, I have given
reference to an accompanying Sheet of Drawings, in which Fig. 1 is a full
size cross section of a stamp head or cutter block as constructed, to be
attached to the slide piece of an ordinary stamping or punching machine;
Fig. 2 is a cross section of another cutter block made to correspond to the
other, and so as to be fixed in position on the bed of the machine; and Fig. 3
is a plan of the same.

page_text: A, B, C, D, E, are a series of circular stamps, punches, or cutters which.
are fixed in the blocks, and so constructed and arranged as to fit within each
other concentrically, that is, the central stamp A is made to fit within the
stamp B, which is a ring whose interior diameter is equal to the exterior
diameter of A, thus forming cutting edges to each other. In like manner
B fits within the ring stamp. C, which again fits within the stamp D, which in
like manner fits within the stamp E, all which stamps are so set in the blocks
respectively that when the said blocks are brought into contact with each
other the edges or outlines of the several stamps or cutters will coincide and
enter within each other, as previously explained, each ring being formed
with a cutting edge to the others adjoining, after the manner of shears.
F, G, H, are rings fitting loosely the spaces betwixt the cutters, which are
kept in this position by pins I and spiral springs J, except when forced back
into the spaces by the cutters. It will now be readily seen that when a
sheet of millboard (as shewn at K) is placed betwixt the two blocks (Fig. 1
and Fig. 2), and the blocks pressed against each other, the cutters will
penetrate through the millboard or cut the same into rings of corresponding
sizes to the cutters, the springs J allowing the rings F, G, H, to give way,
and thus receive the said millboard rings within the spaces betwixt the cutters,
and on the withdrawal or separation of the blocks the springs J will force the
rings F, G, H, back, and thus lift the paper or millboard rings out of the
spaces or grooves betwixt the cutters ready for removal by the attendant.
It will be evident that the stamps or cutters may be made of any size or
diameter required, and any convenient number arranged to act together;
also that other material capable of being cut or stamped, such as lead, gutta
percha, zinc, or other substances, may be cut into corresponding rings by this
means with facility and regularity in size and with less waste of material than
heretofore; also, that any number of cutters may be constructed and arranged
in a similar manner, to act as shears or cutters to each other; also, that such
rings may be employed for packings or making tight the joints of steam,
water or other pipes, or may be used for ends or flanges of bobbins, or for
other purposes.
Having thus fully described the nature of this my said Invention, and the
manner in which the same is or may be performed or carried into practical
operation, I would have it understood that I do not confine myself to any
particular size, number, construction, or arrangement of the stamps, punches,
or cutters; but what I claim as of my Invention is,-
Firstly, the manufacture of rings from sheets of paper, millboard, or other

page_text: materials capable of being cut with stamp, punch, shears, or similar instru-
ments, in manner and for purposes as herein explained.
Secondly, the construction, application, and use of apparatus or instruments
in manner and for purposes substantially as herein described and illustrated
by the accompanying Sheet of Drawings.
In witness whereof, I, the said David Stott, have hereunto set my
hand and seal, this Fourteenth day of October, One thousand eight
hundred and sixty-two.
