page_text: LETTERS PATENT to James Edward Harrison, of Aston, near Birming-.
ham, in the County of Warwick, Weavers' Mail Manufacturer, for
the Invention of "IMPROVEMENTS IN MACHINERY OR TOOLS FOR THE MANU-
FACTURE OF BUTTONS, WASHERS, RINGS, LINKS FOR CHAINS, AND OTHER LIKE
ARTICLES FROM SHEET METAL."
PROVISIONAL SPECIFICATION left by the said James Edward Harrison
at the Office of the Commissioners of Patents, with his Petition,
on the 8th September 1874.
I, JAMES EDWARD HARRISON, of Aston, near Birmingham, in the
County of Warwick, Weavers' Mail Manufacturer, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN MACHINERY OR TOOLS
FOR THE MANUFACTURE OF BUTTONS, WASHERS, RINGS, LINKS FOR CHAINS, AND
OTHER LIKE ARTICLES FROM SHEET METAL," to be as follows:-

page_text: facture of metamic buttons is much economized and simpшned.
My Invention is also applicable to the manufacture of washers, rings,
links for chains, and other like articles from sheet metal.
My Invention is particularly applicable to the manufacture of single
shell sewn-through buttons, and I will describe it in its application to
such buttons.
My Invention consists in arranging the piercing tools by which the
thread holes in the buttons are made in front of the shaping and cutting-
out tools, by which the pierced sheet metal is shaped and cut out, so
that while one part of the sheet metal is being pierced for the said thread
holes the part previously pierced is being shaped and cut out to form a
button. Or when a depression is required to be made around the thread
holes a shaping tool is placed between each piercing tool and cutting-
out tool for forming the said depression previous to the cutting out of
the button.
When buttons are to be manufactured without a central depression I
prefer to construct, arrange, and work the compound tools as follows:-
I arrange and fix on the plate of the moveable tool, which is carried by
and worked in the sliding bolt of the machine, three shaping and a
cutting-out tools, the said tools being arranged in the form of a triangle
on the said plate; and in front of and at a short distance from each
shaping and cutting tool I fix a piercing tool, consisting of four pegs
(if a four-hole button is to be made). On the summit of each of the
first pair of shaping and cutting-out tools is a guide pin or peg, which
on the descent of the moveable compound tool takes into one of the
piercings made in the sheet metal. By means of the said guide pins or
pegs the concentricity of the circumference of the button with the
piercings or thread holes is accurately determined. The fixed or lower
compound tool which is secured on the bed of the machine has in it the
fixed cutting edges and piercing edges for the moveable cutting tools
and piercing tools, and also openings down which the finished buttons.
and the metal pierced out pass.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
EDWARD HARRISON, of Aston, near Birmingham, in the County of
Warwick, Weavers' Mail Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of September, in the
year of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said James Edward Harrison, Her
special licence that I, the said James Edward Harrison, my executors,
administrators, and assigns, or such others as I, the said James Edward
Harrison, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thercafter
during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain
and Ircland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN MACHINERY OR TOOLS FOR THE MANUFACTURE OF BUTTONS,
WASHERS, RINGS, LINKS FOR CHAINS, AND OTHER LIKE ARTICLES FROM SHEET
METAL," upon the condition (amongst others) that I, the said James
Edward Harrison, 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 Invention,
and in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office on or before the Nineteenth
day of March, One thousand eight hundred and seventy-five.
NOW KNOW YE, that I, the said James Edward Harrison, 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 (that is to say) :-
My Invention consists of machinery or tools, constructed and arranged
as herein-after described for piercing, shaping, and cutting out buttons
from sheet metal, by the use of which said machinery or tools the
manufacture of metallic buttons is much economized and simplified.

page_text: | My Invention is also applicable to the manufacture of washers, rings,
links for chains, and other like articles from sheet metal.
My Invention is particularly applicable to the manufacture of single
shell sewn-through buttons, and I will describe it in its application to
such buttons; and in order that my Invention may be readily under-
stood reference is made to the accompanying Drawings, and to the
figures and letters of reference shewn thereon.

page_text: shaped and cut out to form a button; or when a depression is required
to be made around the thread holes a shaping tool F and G is placed
between each piercing tool B and E and cutting-out tool for A and D,
forming the said depression previous to the cutting out of the button.
When buttons are to be manufactured without a central depression I
prefer to construct, arrange, and work the compound tools as follows:-
I arrange and fix on the plates of the moveable tool, Fig. 1, which is
carried by and worked in the sliding bolt of the machine three shaping
and cutting-out tools A, the said tools being arranged in the form of a
trianglo on the said plate; and in front of and at a short distance from
each shaping and cutting tool I fix a piercing tool B consisting of four
pegs (if a four-hole button is to be made). On the summit of each of
the first pair of shaping and cutting-out tools, see Fig. 2, is a guide
pin or peg H, which on the descent of the moveable compound tool takes
into one of the piercings made in the sheet metal. By means of the said
guide pins or pegs the concentricity of the circumference of the button
with the piercings or thread holes is accurately determined. The fixed
or lower compound tool, Fig. 6, which is secured on the bed of the
machine, has in it the fixed cutting edges and piercing edges for the
moveable cutting tools and piercing tools, and also openings down which
the finished buttons and the metal pierced out pass.
In commencing the manufacture of the buttons by the use of my
Invention the sheet metal is fed across the lower fixed compound tool,
Fig. 6, until the edge is beyond the first part of piercing tools E. On
the sheet metal coming to rest the moveable compound tool, Fig. 1,
descends and pierces in the sheet metal two groups of thread holes. The
moveable tool, Fig. 11, rising the sheet metal is again fed forward,
when the piercings or holes in the sheet metal are brought opposite the
front pair of shaping and cutting-out tools A, D. By the descent of the
upper compound tool, Fig. 1, the metal around the groups of thread
holes is first shaped or domed," and afterwards cut out, and two
buttons are made which fall down the openings in the lower tool D.
The further feeding of the sheet metal brings it opposite the third
piercing tool and third shaping and cutting-out tool. When the sheet
metal has been so fed at each descent of the compound moveable tool,
Fig. 1, three groups of piercings are made in the sheet metal, and
three buttons are shaped and cut out, the piercings made by the last
descent of the compound tool, Fig. 1, forming the thread holes in the
1.

page_text: Duttons shaped and cut out by the next descent of the compound tool,
Fig. 1.
For convenience of description I have described only three sets of
tools, but a greater number may be advantageously employed, and I do
not limit myself to the number or positions of the piercing, shaping, and
cutting-out tools.
When the thread holes are situated in a depressed part in the centre
of the button a tool F and G for shaping, the said depressed part is
fixed between the piercing B and E and cutting-out tools A and D of
each pair, the metal being first pierced, the part around the piercings
next shaped, and the button finally cut out, three finished buttons being
made at each descent of the compound tool, Fig. 1.
In making washers, rings, chain links, and other like articles, by the
use of my Invention I cut out the inner edge of the washer, ring, or
link by one piercing tool, and the outer edge or circumference of the
said article by a second tool, the said tools being arranged substantially
in the manner herein-before described with respect to tools for the
manufacture of buttons.
Having thus described the nature of my said Invention, and the
manner of carrying the same into effect, I declare that what I claim and
desire to be secured to me by the herein-before in part recited Letters
Patent is, the improvements in machinery or tools for the manufacture
of buttons, washers, rings, links] for chains, and other like articles
from sheet metal, substantially as herein-before described and illustrated
on Drawings, or any mere modification thereof.
In witness whereof I, the said James Edward Harrison, have here-
unto set my hand and seal, this Nineteenth day of March, in the
year of our Lord One thousand eight hundred and seventy-five.
