page_text: LETTERS PATENT to Chauncey Orrin Crosby, of New Haven, in the County
of New Haven, and State of Connecticut, United States of America, for
the Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR TAPER-
ING, POINTING, OR REDUCING WIRES OR RODS FOR SPINDLES, HATCHEL TEETH,
PINS FOR DRESSES, AND SIMILAR ARTICLES."
Sealed the 10th November 1865, and dated the 16th May 1865.
PROVISIONAL SPECIFICATION left by the said Chauncey Orrin Crosby
at the Office of the Commissioners of Patents, with his Petition, on the
16th May 1865.
I, CHAUNCEY ORRIN CROSBY, of New Haven, in the County of New Haven, and
State of Connecticut, United States of America, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
TAPERING, POINTING, OR REDUCING WIRES OR RODS FOR SPINDLES, HATCHEL TEETH,
PINS FOR DRESSES, AND SIMILAR ARTICLES," to be as follows:-
This Invention relates to improvements in machines for reducing and
tapering, or pointing wire or other metal rods, such as spinning spindles,
batchel teeth, dress pins, and similar articles; and, consists in placing auto-
matically or otherwise the pieces of metal to be tapered, reduced, or pointed
into revolving spindles, which will present the said pieces successively to one
or more rapidly vibrating hammers, the said spindles having a lateral move-
ment for introducing each piece under the hammer, and withdrawing it there-

page_text: from, for enabling the hammers gradually to draw the wire tapering, or
reduce it in diameter, or form it to a point as desired.
These improvements will be clearly understood by referring to the figures
and letters on the accompanying two Sheets of Drawings, in which Fig. 1 is
a top view of my improved tapering, pointing, or reducing machinery or appa-
ratus; Fig. 2 a vertical section of part of the same; Fig. 3 a wire or rod,
baving an oval point as formed by the machine; and Figs. 4 and 5 are end
and side views of one part of the machine.
A represents the bed plate on which the operative mechanism is placed;
B, a driving shaft revolving in bearings C, and driven by power being applied
to the pulley D; E, represents the feed operated by the cam F through the
lever G for drawing the wire into the machine; H is a cutter operated by
the cam I for cutting off the wire or rod when fed the required length; K are
spindles, supported in bearings L on the plate M, Figs. 1 and 2, which spindles
are made to revolve by means of the wheel N revolving against the pulley a,
one on each of the said spindles; O is a cone fixed to a shaft P, and caused
to rise and fall by means of the cam R acting through the lever S, upon
which the said shaft P rests; the upward movement of the said cone O bearing
against the inner ends of the spindles K will cause the said spindles to
move out, and its descent will allow them to return by the action of the
springs Z. The plate M on 'which the spindles K are placed is turned in
the direction denoted by arrows by means of the pawl T, operated by the
cam U through the lever W as shewn in Fig. 1, so that at each movement
of the plate M a new spindle K is presented to the feed to receive a new
piece of metal. A¹ are hammers placed upon the bed plate A radially from
the plate M, and opposite the spindle K as seen in Fig. 1. One of the said
hammers is shewn in Fig. 2. 6 is a die secured to the bed of the hammer;
c is a corresponding die hung to the bed of the hammers as far back as pos-
sible in order to make the vibration of the die c nearly perpendicular. Each
hammer A¹ is hung upon a fulcrum d, its shorter end bearing upon the uppèr
die c, and its longer arm upon the cam B' fixed to a shaft C', which is sup-
ported in bearings D', and revolves by the application of power to the
pulley E. The outer ends of the spindles K are fitted to receive and hold
the metal fed to them in the following manner, as seen in Fig. 2. A hole of
the proper size and depth is formed' in the end of the spindle, a lever'e Kung
within the spindle upon a fulcrum f, bears down upon the wire by 'the force
of the spring. Around the said spindle and over the lever e is placed a ring i
when the said ring i is forced back to the position denoted in blue, it will
press down the inner end of the lever e, and open the outer end, in which

page_text: position it is ready to receive the wire from the feed E. The operation of my
machine is as follows:-The square or round wire or rod, or whatever it may
be required to reduce, is passed through the feed E and guide ;. power is
applied to the pulley D to revolve the driving shaft, and to each of the
hammers, and also enable the pulley F¹ to turn the wheel N. The feed
carries the wire into the spindle presented to the guide n as denoted in blue,
Fig. 1, and the wire is cut off by the cutter. H, and then by the action of the
pawl T the plate M revolves sufficiently to present the next spindle to
receive a second piece of wire, in which movement the ring i passes the
inclined plane p, which forces the said ring forward to enable the lever e to.
grasp and hold the metal therein, and so continuing, each spindle as it is
presented to the feed receives its piece of wire, and presents it to the first
hammer which is vibrating rapidly; the inclined plane O now rises by
action of the cam R and forces the spindles forward, thereby inserting the
wire between the dies and c; the inclined plane O then descends slowly,.
allowing a spindle to withdraw the wire from the dies b and c, the spindle K
revolving whilst the wire is between the dies, is hammered upon every side,.
and gradually drawn down, the form of the Drawing, whether oval as seen.
in Fig. 3, or conical or parallel, may depend upon the withdrawing of the wire
from the dies, or the dies may be constructed to give the required form, or the
wire may be allowed to remain in the first dies sufficiently long to complete
the form desired, in which case only a single hammer would be required, but
I prefer more hammers, and less labour for each. When the wire is with-
drawn from the first bammer, the spindles are advanced by another action of
the pawl T for presenting the wire to the next hammer, whilst the second.
wire is operated upon by the first hammer as before, and so on, presenting the
several wires successively to each hammer until the last, where it is finished,,
thence advancing until the ring i comes in contact with the inclined plane p,
which forces the said ring i back to the position denoted in blue, Fig. 2, and
from thence passing on to the discharging device Y, when the spindle, still
retaining the wire, forces it beneath a spring Q (see Figs. 4 and 5),
which is sufficiently strong to retain the wire while the spindle retreats; the
next spindle leaves its wire in like manner, the second forcing the first out
from the spring, and so on, the spindle passing on to the feed to receive a new,
piece of wire.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHAUNCEY
ORRIN CROSBY, of New Haven, in the County of New Haven, and State of
Connecticut, United States of America, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters.
Patent, bearing date the Sixteenth day of May, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Chauncey Orrin Crosby, Her special licence that I, the said Chauncey
Orrin Crosby, my executors, administrators, and assigns, or such others as
I, the said Chauncey Orrin Crosby, 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 "IM-
PROVEMENTS IN MACHINERY OR APPARATUS FOR TAPERING, POINTING, OR REDUCING
WIRES OR RODS FOR SPINDLES, HATCHEL TEETH, PINS FOR DRESSES, AND SIMILAR
ARTICLES," upon the condition (amongst others) that I, the said Chauncey
Orrin Crosby, 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 within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said Chauncey Orrin Crosby, 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) :-
This Invention relates to improvements in machines for reducing and
tapering, or pointing wire or other metal rods, such as spinning spindles,
hatchel teeth, dress pins, and similar articles; and, consists in placing auto-
matically or otherwise, the pieces of metal to be tapered, reduced, or pointed
into revolving spindles, which will present the said pieces successively to one
or more rapidly vibrating hammers, the said spindles having a lateral move-

page_text: ment for introducing each piece under the hammer, and withdrawing it there-
from for enabling the hammers gradually to draw the wire tapering, or reduce
it in diameter, or to form it to a point as desired.
These improvements will be clearly understood by referring to the figures
and letters on the accompanying two Sheets of Drawings, in which Fig. 1 is a
top view of my improved tapering, pointing, or reducing machinery or appa-
ratus; Fig. 2 a vertical section of part of the same; Fig. 3 a wire or rod,
having an oval point as formed by the machine; and Figs. 4 and 5 are end
and side views of one part of the machine.
A represents the bed plate on which the operative mechanism is placed;
B, a driving shaft revolving in bearings C, and driven by power being applied
to the pulley D; E represents the feed, operated by the cam F through the
lever G, for drawing the wire into the machine; H is a cutter operated by
the cam I for cutting off the wire or rod when fed the required length; Kare
spindles supported in bearings L on the plate M, Figs. 1 and 2, which spindles
are made to revolve by means of the wheel N revolving against the pulley a,
one on each of the said spindles; O is a cone fixed to a shaft P, and caused
to rise and fall by means of the cam R acting through the lever S, upon
which the said shaft P rests; the upward movement of the said cone O
bearing against the inner ends of the spindles K, will cause the said spindles,
to move out, and its descent will allow them to return by the action of the
springs Z. The plate M on which the spindles K are placed is turned in the
direction denoted by arrows by means of the pawl T, operated by the cam U
through the lever W, as shewn in Fig. 1, so that at each movement of the
plate M. a new spindle K is presented to the feed to receive a new piece of
metal. A' are hammers placed upon the bed plate A radially from the plate M,
and opposite the spindles K as seen in Fig. 1. One of the said hammers
is shewn in Fig. 2. b is a die secured to the bed of the hammer; c is a
corresponding die hung to the bed of the hammers as far back as possible in
order to make the vibration of the die c nearly perpendicular. Each hammer,
A is bung upon a fulcrum d, its shorter end bearing upon the upper die c,
and its longer arm upon the cam B' fixed to a shaft C, which is supported
in bearings D', and revolves by the application of power to the pulley.E'. The
outer ends of the spindles K are fitted to receive and hold the metal fed to
them in the following manner, as seen in Fig. 2. A hole of the proper size
and depth is formed in the end of the spindle, a lever e hung within the
spindle upon a fulcrum f, bears down upon the wire by the force of the spring;
around the said spindle, and over the lever e is placed a ring i; when the said

page_text: ring i is forced back to the position denoted in blue, it will press down the inner
end of the lever e, and open the outer end, in which position it is ready to
receive the wire from the feed E. The operation of my machine is as
follows: The square or round wire or rod, or whatever it may be required
to reduce, is passed through the feed E. and guide n; power is applied to the
pulley D to revolve the driving shaft, and to each of the hammers, and also
enable the pulley F¹ to turn the wheel N. The feed carries the wire into the
spindle presented to the guide n as denoted in blue, Fig. 1, and the wire is
cut off by the cutter H, and then by the action of the pawl T the plate M
revolves sufficiently to present the next spindle to receive a second piece of
wire, in which movement the ring i'passes the inclined plane p, which forces
the said ring forward to enable the levere to grasp and hold the metal therein,
and so continuing, each spindle as it is presented to the feed receives its piece
of wire, and presents it to the first hammer which is vibrating rapidly; the
inclined plane O now rises by action of the cam R, and forces the spindles
forward, thereby inserting the wire between the dies band c; the inclined.
plane O then descends slowly, allowing a spindle to withdraw the wire from
the dies b and c, the spindle K revolving whilst the wire is between the dies,
is hammered upon every side, and gradually drawn down. The form of the
drawing, whether oval, as seen in Fig. 3, or conical or parallel may depend
upon the withdrawing of the wire from the dies; or the dies may be con-
structed to give the required form, or the wire may be allowed to remain in
the first dies sufficiently long to complete the form desired, in which case. only
a single hammer would be required, but I prefer more hammers and less
labour for each. When the wire is withdrawn from the first hammer the
spindles are advanced by another action of the pawl T for presenting the wire
to the next hammer, whilst the second wire is operated upon by the first
bammer as before, and so on, presenting the several wires successively to each
hammer until the last, where it is finished, thence advancing until the ring i
comes in contact with the inclined plane p, which forces the said ring i back
to the position denoted in blue, Fig. 2, and from thence passing on to the
discharging device Y, when the spindle, still retaining the wire, forces it
beneath a spring 2 (see Figs. 4 and 5), which is sufficiently strong to retain
the wire while the spindle retreats; the next spindle leaves its wire in like
mauner, the second forcing the first out from the spring, and so on, the spindle
passing on to the feed to receive a new piece of wire.
Having therefore thus fully described my Invention, what I claim as new
and useful is-

page_text: Firstly, the vibrating hammering dies A¹in combination with the spindles K,
constructed and operating in the manner described.
Secondly, the vibrating hammering dies, and the spindles K, constructed
and operating in the manner described, in combination with a feeding device E,
as described.
And, thirdly, the vibrating hammering dies and the spindles K, constructed
and operating in the manner described, in combination with the discharging
device Y.
In witness whereof, I, the said Chauncey Orrin Crosby, have hereunto
set my hand and seal, this Eleventh day of October, in the year of our
Lord One thousand eight hundred and sixty-five.
