Year: 1875

page_text: LETTERS PATENT to William Trabue, of Louisville, in the County of
Jefferson, and State of Kentucky, one of the United States of
America, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE
OF NEEDLES AND APPARATUS THEREFOR.
COMPLETE SPECIFICATION filed by the said William Trabue at the
Office of the Commissioners of Patents, with his Petition and
Declaration, on the 23rd February 1875, pursuant to the 9th
Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
TRABUE, of Louisville, in the County of Jefferson, and State of Ken-
tucky, one of the United States of America, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
THE MANUFACTURE OF NEEDLES AND APPARATUS THEREFOR," and have petitioned
Her Majesty to grant unto me, my executors, administrators, and
assigns, Her Royal Letters Patent for the same, and have made solemn
Declaration that I am the true and first Inventor thereof.

page_text: NOW KNOW YE, that I, the said William Trabue, do hereby declare
that the following Complete Specification, under my hand and seal,
fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be performed, in and by the following
statement, that is to say :-
My Invention has for its object to cheapen the cost of the production
of needles by facilitating the manufacture thereof.
My Invention consists in the combination of devices whereby the
needle wire is pressed into shape and the excess of metal cut away, as
will be herein-after more fully set forth.
To enable those skilled in the art to fully understand my Invention,
I will proceed to describe the same, referring by letters to the accom-
panying Drawings in which,—
Figure 1 is a top view of a machine embodying my Invention;
Figure 2, a side elevation of the same; Figure 3 an end view.
Figure 4, a detail view, exposing to view the face of one of the rotary
dies and the cutters for cutting away the excess of metal in the forma-
tion of the needle; Figure 5 is a detail view of the same at right angles
to the above showing the needle blank or wire in section; and Figure 6
is a detail plan view of one of the rotary dies with the needle in position
as formed.
Similar letters indicate like parts in the several Figures.
A represents a suitable casting adapted to receive two horizontal
shafts B, B, which are provided at one end with meshing gears C, O,
and at the other with rotary dies D, D, which may be secured in position
and removed at will. The casting A is bifurcated from a suitable
distance from the gear end, as seen at E, and near its forward or cutting
end is flattened or spread out, as seen at F, and cut away at G to allow
the free rotation of of the revolving dies D, D. H, H, are revolving
cutters whose axes are tranverse or at right angles to the shafts of the
dies D, D, and mounted in the bifurcated ends of blocks I, I, adapted
to slide horizontally in the direction of axes of the die shafts, as shewn
by the arrows in suitable ways within the bifurcated casting A. A
head piece J at the end of the machine, and a block K opposite thereto,
serve as bearings for spring screw rods L which carry springs m, m,

page_text: may be varied without departing from the peculiar character of my In-
vention, but what I do claim is,-
-
1st. In a machine for making needles the combination with the rotating
dies D, D, of the revolving cutters H, H, hung in moveable bearings,
substantially as and for the purposes described.
2nd. The sliding blocks I, I, provided with revolving cutters H, H,
in combination with the rotary dies D, D, having cam surfaces a, b,
whereby the cutters are automatically brought toward or forced from
the blank, substantially in the manner and for the purpose set forth.
3rd. In combination with the cam faced dies and sliding blocks the
screw bolts L, springs m, and block K, or head J, substantially as and
the purpose set forth.
4th. The frame A bifurcated and otherwise constructed as described,
to form bearings for the die and cutter shafts, as herein-before set forth.
In witness whereof, I have hereunto set my hand and seal, this
Sixth day of February, in the year of our Lord One thousand
eight hundred and seventy-five.
