page_text: LETTERS PATENT to Orin. Lewis Hopson and Heman Porter Brooks, of
Waterbury, in the State of Connecticut, United States of America, for
the Invention of "AN-IMPROVED MACHINE OR APPARATUS FOR POINTING
WIG Bone non De
Sealed the 21st March 1865, and dated the 14th October 1864.
PROVISIONAL SPECIFICATION left by the said Orin Lewis Hopson and
Heman Porter Brooks at the Office of the Commissioners of Patents;
with their Petition, on the 14th October 1864.
We,.ORIN, LEWIS HOPSON and HEMAN PORTER BROOKS, of Waterbury, in
the State of Connecticut, United States of America, do hereby declare the
nature of the said: Invention for "AN IMPROVED MACHINE OR APPARATUS
FORT POINTING WIRES OR RODS FOR PINS AND OTHER ARTICLES," to be as
follows:
We make use of a revolving shaft; in the end of which is a divided:die
formed with ai hole of the shape to be given to the end of the wire, to'form' a
point thereon or to give to the end of said wire any shape that may be formed
in said dies! One half of this divided die is secured firmly in a recess formed

page_text: at the end of said revolving shaft, the other half is attached in the same recess
by means of a pin, so that it is held in place but allowed to move away suffi-
-ciently-from-the-fixed-half-of-the-die-for-the-introduction-of-the-wire-or-rod-to-
be pointed or shaped. The die is limited in the amount that it can open by a
set screw passing through a ring around and revolving with said shaft. A
series of adjustable blocks standing radially around the end of this revolving
shaft act as stationary cams to press one part of said divided die towards the
other as said divided die revolves, with said shaft, the opening between said
dies being on the axial line of said shaft.
The end of the wire or rod to be pointed or otherwise shaped is entered
between these dies and forces theni slightly apart, and as they revolve the
stationary cams close the dies, compressing the point of the wire or rod, and
bringing the same to a perfect point, or giving to the same whatever shape is
formed in the dies, and the rotary motion at the same time smooths and
renders perfect the shaping of the wire or rod at the end. This operation is
performed very fast and at the same time very perfectly, and may be employed
for pointing pins, or nails, or forging any small round articles.

page_text: lawfully might make, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "AN IMPROVED MACHINE OR APPARATUS FOR POINTING WIRES OR RODS
FOR PINS AND OTHER ARTICLES," upon the condition (amongst others) that wey
the said Orin Lewis Hopson and Heman Porter Brooks, by an instrument
in writing under our 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 Orin Lewis Hopson and Heman
Porter Brooks, do hereby declare the. nature of our said Invention, and ini
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, reference being had to the
Drawing hereunto annexed, and to the letters. and figures marked thereon
(that is to say) -
:
-
Fig. 1 is a longitudinal section of our improved means for pointing
دو
wire; and
.
2 is an end view representing the cams for actuating the pointing dies.
The nature of our said Invention consists in pointing wires or rods by a
revolving, divided die that is pressed together two or more times during each
revolution, said die being of the shape required for the point, and hence the
wire forming the point is gradually compressed and extended to the form
and shape required at said point, without producing any bur (as usual in
the compressing, and pointing dies heretofore employed) and the point is.
consolidated and rendered much harder than when reduced to shape by filing
or grinding..
In the Drawing a is the mandrel head or frame carrying the mandrel or.
shaft that is driven by competent power applied at the pulley or wheel c.
Near the end of this shaft is a longitudinal groove or recess receiving the
jaw d that is held in place by the cross pine or other suitable means, so-
that said jaw d can receive a slight swinging or opening movement to receive
the wire between the parts on the line of the centre or axis of the said shaft b;
fis a ring around band d, with a screw 9 passing through the same and
entering a cavity in d; this screw graduates the amount the jaw d can move..
or open for the admission of the end of the wire to be pointed. i, i, are dies
formed with an opening of the shape of the point required, and the respective

page_text: parts of the die are attached to b and d, so that, the cavity in said dies is on
-the-axial-line-of-the shaft b. Around the end of this shaft 6 is a stationary
ring with radial slots receiving the cams-k that are adjusted by the screws-?-
or other suitable means.
The mode of operating this. machine is as follows:-The end of the piece of
wire to be pointed or otherwise shaped is entered between the dies i, i, and
pressed into them, which slightly opens said dies. The revolution of the shaft c
brings the projection o of the jaw d into contact with the end of one of the
cams k, which cam is adjusted so that it will close the dies i, i, and in so doing
compress the wire or rod, and these operations are repeated, the end of the
wire being pressed in a little farther each time the jaw is relieved, and allowed
to slightly open until the point is perfectly formed, which point is of the
shape of the die opening, and is compressed and extended without forming
any bur or projection on the same, and the point is rendered much harder by
this compressing action than would be the case if the metal was filed or
ground away to form the point.
It will be evident that if only two cams were employed they would
require to be at right angles to each other, so as to operate on both sides of
the wire; and where a larger number of radial cams are used the operation
of forming the point will be effected equally fast with a slower rotation of the
shaft than in cases where but few of these radiating cams are employed.
This mode of pointing has the.effect of smoothing the surface acted upon by
the rotary movement of the dies.
. The mechanism herein set forth may be employed for shaping in a circular:
form any other article besides a point to which it may be adapted.
It will be evident that there is no waste of material, as the point is
compressed and elongated, thus effecting a saving of stock over the methods
heretofore pursued, and making a much better article.
In Fig. 3 a variation is shown in the mode of fitting the jaw d; in this the
fulcrum e is located near the centre of the jaw, the ring f is dispensed with,
and the screw introduced at the rear end, so as to regulate the amount that
the diés i may open as the wire is pressed in.
What we claim and desire to secure by Letters Patent is,
First, pointing wires or rods by a revolving divided die that is pressed:
together, substantially as and for the purposes specified.
Second, we claim the arrangement of the adjustable radial cams k, revolving
shaft b, jaw d, and dies i, substantially, as specified...

page_text: Third, we claim the ring f and screw g in combination with the jaw d, and
dies i, i, for regulating the amount said dies shall be allowed to open, as set
forth.
In witness whereof, we, the said Orin Lewis Hopson and Heman
Porter Brooks, have hereunto set our hands and seals, this 28th day of
February, in the year of our Lord. One thousand eight hundred and
sixty-five..
