me, my executors, administrators, and assigns, Her Royal Letters
Patent for the same, and have made solemn Declaration that it has
been communicated to me from abroad by Daniel T. Lyman, of Pro-
vidence, Rhode Island, United States of America.
NOW KNOW YE, that I, the said George Haseltine, 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, reference being had to the accompanying Drawing forming a
part of this Specification.
This Invention has for its main object the manufacture of thread
spools from cylindrical wooden blocks or blanks, including the stamping
or embossing on one or both heads of the spool of a trade mark, name,
or other device, and consists in such a combination of the various parts
that all the operations in such manufacture are performed in one
machine.
The blanks are submitted to three principal operations, namely, first,
planing or smoothing the ends, and boring the hole called heading and
boring; second, stamping the ends; and third, turning the barrel of the
spool. The blanks are transmitted in succession by automatic machinery
from the place where they are first introduced into the machine to
different points where these several operations are performed. These
blanks are first prepared for the machine by being turned to the requisite
diameter and sawed to the proper length for the spools intended to be
made, and are then placed in the end of a conductor adapted in this part
of it to hold a considerable quantity. They are then drawn in succession
by mechanism adapted to the purpose through the conductor into that
part of the machine where the heading and boring are performed. As
fast as this work is completed on each blank it is transmitted through a
conductor, which is a mere continuation of the one already mentioned,
to a stamp, and thence along the same conductor to a lathe, which
finishes the spool by turning the barrel, and drops it from the
machine.

machine.
.
A is the frame of the said machine, which frame should be of substantial
construction to resist the vibrations of the operating parts; P is the
driving pulley, which is hung on a shaft B, from which motion is com-
municated to cam shaft B' by means of a shaft B" and gear wheels D, 'D',
D', D³. On cam shaft B¹ are hung the cam wheels C, C¹, 0³, C³, Oʻ, Ơ³,
the three latter having cam grooves cut in the sides or faces, and C³ also
having a small cam c on its periphery; S, S¹, are revolving spindles, on
the inner ends of which are bits 6, 61, for boring the hole, and at right
angles to the bits are set knives in the ends of the spindles for planing
and smoothing the ends of the blanks. These spindles are made to
reciprocate or slide horizontally forward and backward by levers 1, P,
operated by cams. C, C³, for the purpose of boring the hole, and are so
moved that one bit pierces a little past the centre of the blank, and
begins to retire before the other bit can meet it. This latter bit passes
a little beyond the limit of the first, thus securing a clear hole through
the blank. H is the block holder or spool clamp, of which the top is
stationary, while the bottom is provided with a vertical clutch / working
up and down in grooves. In the arrangement for working the clutch h
it is desirable to provide against any danger of breakage in case a blank
or other hard substance should get into the jaws of the block holder in
such a way as to prevent the rising of the clutch as far as intended. For
this reason the lever & is hung on an elliptic springs (shown in dotted
lines in Figures 2 and 3), and has one end attached to clutch h, and the
other end connected with one end of the lever . This lever extends
across the machine, as shown in Figure 2, and is attached to the frame
on the opposite side. By the action of cam C this lever causes lever &
to oscillate and work clutch / in the manner described. The spring s is
sufficiently stiff to enable the clutch to do its proper work, but in case of
any unusual resistance the spring yields, and the extra strain on the
machinery is thus avoided. In place of the two levers ľ, P, a single
·

page_text: The stamping or embossing is performed after the blank has left the
block holder, and is on its way to the lathe. Two upright or nearly upright
lovers u, u', with proper supports are placed one on each side of the
conductor along which the blank passes, the blank being in a horizontal
position, and lying across the conductor. To the lower ends of u and u
are attached two other levers u", 111, which come together so as to form
an elbow or toggle joint e, Figure 3. This joint rests on and is fastened
to an arm a projecting from the side of the frame at some convenient
point, and is attached to the frame by a hinge. The other end of the
arm projects over the cam c on cam wheel C³.
20
On the top of levers and u¹ are placed cross pieces t, t, as shown in
Figure 1. The inner ends of these pieces are fitted with dies for
stamping, and also with centres of about the diameter of the hole in the
blank, and tapered slightly at the ends. The centres are thus tapered to
render more certain their taking up of the blank if the hole should not
come in a direct line with the centres at the proper time. By the revo-
lution of cam wheel C³ cam c lifts the end of arm a, and with it the
elbow e, thus throwing outward the lower ends of u and u', and bringing
the dies in contact with the ends of the blank through an opening pro-
vided in the sides of the conductor. To bring the dies back, and set the
blank free from the dies and centres after the stamping, the end of the
arm a is made to fall after the cam c has passed under it by connecting
the end of the arm with a groove in the side of the cam wheel C³ cut to
operate like a cam.
The time occupied in stamping and freeing the blank is diminished by.
a knob or protuberance placed on the under side of the cam a, as shown
by dotted lines at k, Figure 2; S2, Figure 1, is a spindle made to slide
horizontally by a lever "actuated by cam C. This lever may be attached
to the frame, and then bent toward the cam on the one hand, and toward
the spindle S² on the other, so as to act like a crank.
Spindle S² is provided with a centre i to fit loosely in the hole of a
blank, which after stamping is placed by appropriate mechanism in a
line with this spindle. The said spindle is then brought forward by
lever 1, and taking the blank upon the centre i, presses it upon the
centre i¹ of the revolving spindle S³. This centre i has flanges in the
usual way, but as spindle §³ is revolving rapidly, if the flanges should
strike the wood before the blank begins to revolve, they would cause

page_text: 4
more or less reaming. To obviate this difficulty a ball or knob o,
Figure 1, fitting snugly in the hole, is placed on the end of a centre i
between the flanges and the blank, and enters the hole in advance of the
flanges and causes the blank to begin its revolutions before it reaches
the flanges. The thrce revolving spindles take their revolutions from
shafting outside of the machine by means of belts and pulleys. The
knife carriage K (shown in Figure 1 'and in section in Figure 2), may
be of the ordinary construction, and is moved by lever, shown in part
in Figure 3, and by dotted lines in Figure 2 in connection with cam C",
Figure 3.
The Drawings show the lever 1 projecting nearly vertically downward
from the point where it is attached to the knifo carriage, and then bent
toward cam C', forming nearly a right angle, as shown in Figure 2; at
this angle a joint is made in the lever which allows the opening of the
angle contained between the two parts of the lever, but prevents its
closing to less than the angle fixed upon in the contraction of the lever...
The cam C* works against the end of the lower arm of this lever in
drawing up the knife carriage toward the blank and depresses it, and
tends to open the joint. A spring s¹, Figure 2, keeps this joint closed
unless the knives or carriage in advancing meet with some undue
resistance. This might happen if from some defect in the wood, a blank
should fail to revolve. In such case the spring s¹ allows the joint to
open until the cam has ceased to act in that direction. The carriage
stops or comes up more slowly, according to the amount of resistance,
and the danger of breaking any part of the machinery is entirely obviated
or greatly reduced. Various other means may be employed to accomplish
the same end, such as the clutch / and the lever operating it.
The conductor Y (shown in Figure 1, and in longitudinal section in
Figure 2) extends from behind the block holder nearly to the lathe in
the front part of the machine. It should be of sufficient width and.
depth to allow the blanks to pass freely through its whole length in the ;
manner shown in Figure 2, and sufficiently closed on all sides to prevent
the escape
of the blanks as they are pushed along. It consists of two
parts, the portion behind the block holder, and that portion between the
block holder and lathe. These two parts form one conductor. m, m³, m¹,
are sleeves or sliding bands upon the conductor, the two latter being
connected by rods which run in grooves in the bottom of the conductor,
and also by a rod r, Figure 1. A connecting rod 1 extends from m¹ to'm

page_text: through the block-holder, so that the three sleeves m, m², m¹¹, are all
thus connected and move simultaneously by the operation of lever 1,
Figure 2, in connection with the came groove in cam wheel 0³. v, v²,
Figure 1, are carriages running in grooves made in the inner surfaces of
the sides of the conductor near the top. To these carriages are attached
movable pawls p, p', Figure 2, with slotted necks extending upward,
through which the rod » passes to give them motion. These pawls are
intended at each forward movement to engage a single blank, and carry
it forward a distance equal to its diameter, but as the travel of any fixed
point on the rod r, would in most, if not in all, cases exceed the length
of such diameter, the rod r is allowed to pass freely through the slots in
the first part of its travel in either direction, and shoulders or projections.
on the rod then carry the pawls the remaining distance. The space
over which the pawls are thus made to travel, is easily regulated by
placing the shoulders nearer together or farther apart. Adjustable bands
or sleeves around the rod and provided with a set screw form a con-
venient means for adapting the movements of the pawl to different sized
blanks. The pawl p attached to carriage is intended to place a blank
directly between the dies, and is so shaped as to embrace a portion of
the top of the blank, and prevent its going beyond its destination, until
it is caught by the centres which hold it during the act of stamping.
A carriage similar to those described with a pawl like that attached to
carriage v¹ is placed in that part of the conductor which is behind the
block holder, and is moved by rod ² extending back from sleeve m with
shoulders like rod r. The pawls are so attached to the carriage by:
hinges or other means that with a slight friction of the carriages in the
grooves the lower ends of the pawls will be lifted up in their backward
travel and pass clear of the blanks, and will be dropped down on starting
forward to engage a blank. These several movable pawls are intended
to assist in moving a column of blanks filling the whole length of the
conductor, and they so operate in connection with other mechanism that
at the instant at which a blank is taken out of the mouth of the con-
ductor to go into the lathe another blank is taken into the line out of
the reservoir of blanks in the back end of the conductor, and the whole
series is moved forward a distance equal to the diameter of one blank,
the blanks being supposed to be of uniform size.
If the conductor were placed at an angle so as to incline towards the
lathe, or if it were placed in a perpendicular position the blanks might

page_text: -
find their way through it without the aid of the pawls, but it is believed
that owing to some slight irregularities in the size of the blanks, which
is unavoidable, and to their lightness and other reasons, the assistance.
of a greater or less number of pawls, such as described, or other
similar means, is necessary for delivering the blanks constantly and with
certainty at the required points. n is a stationary pawl in the conductor,
so hung as to allow the blanks to pass under it toward the block holder, .
but prevents their return. 83, 8³, are springs, which hold the blanks
from falling out of the mouth of the conductor after passing in front of
the stationary pawl n.
In Figure 2, f,f', are fingers or springs attached to and moving with
sleeve'm, and which in drawing back take hold of the blank lying
directly in front of pawl n, as shown. These fingers carry the blank
forward and place it in the jaws of the block holder, which are hollow or
concave so as to fit the form of the blank, and to insure its position in a
line with the spindles, as well as to hold it more firmly. The clutch h
rising at the same instant grasps and holds the blank firmly in the
proper position for heading and boring, while by a reverse motion the
fingers are drawn back to take up another blank, which in the meantime.
has been pushed forward under the stationary pawl n. ƒ³,ƒ³, are also
fingers attached to sleevo m, and similar to those already described, but
of greater length, and which moving simultaneously with f,f¹, grasp
the blank in the block holder before the clutch h has set it free, and
after it is so released carry it into the conductor in front of the block
holder.
Springs 8, 8, Figure 1, in the sides of the conductor with a shoulder
in their inner surfaces catch hold of the blank and retain it in the
conductor. This blank is in turn pushed forward by the succeeding
blank or blanks until it comes within reach of a pawl. ƒ', ƒ³, åre
fingers attached to sleeve m", and take the blanks in succession. from
the mouth of the conductor and place them in the lathe in such a
manner that they are taken upon the centres of the spindles S³, S³, as
already explained. These fingers operate precisely like f, f¹, in taking
hold of the blank in the conductor, and aro assisted by a stationary
pawl, Figure 2, performing the same office as pawl n.
In the end of the conductor, where the blanks are first introduced, the
bottom may be made to incline slightly toward the block holder, so that
the blanks will roll forward as fast as those in front are taken away.

page_text: A shoulder or ledge d, Figure 2, in the bottom, over which the blanks
are allowed to fall, prevents them from being pushed back by the
pawl in case it should chance to drag over them in moving back.
In place of the inclined plane, or in conjunction with it, a sliding
carriage 9, shown in part in Figure 2, is found useful in drawing the
blanks toward the first pawl and keeping it constantly supplied. This
carriage is shaped like a carpenter's mitre box or a cigar box, with the
top and both ends removed, and across, the bottom of such carriage are
fastened two. rods q, q', projecting beyond the sides, like trunnions or
journals, and which rest on a railway y placed under and parallel
with the conductor, "A connecting rod ³, with joints, connects the
carriage with sleeve m, so that they move together. Longitudinal slots or
channels, seen in Figure 1, are cut in the bottom of the conductor in
which the sides of the carriage run. When the carriage rests on the
railway these sides should not be high enough to touch the blanks in the
conductor, but when it is drawn forward with the sleeve m the journals
pass over little inclined planes X, X', resembling pawls fixed over the
rails, and which raise the sides of the carriage through the channels so
that they will lift the blanks and draw them forward. The journals,
after passing over the elevations, fall down upon the rails again and pass
under the pawls in returning. The edges of the carriage brought into
contact with the blanks may be roughened or serrated to render them
more effective in removing the blanks.
When it is desired to make plain spools the stamping apparatus may
be removed or disconnected.
By means of this Invention not only spools but pail handles and a
variety of other articles in daily use may be made with great rapidity
and of a quality equal or superior to those made by the ordinary
means.
Having thus fully described the said Invention as communicated to
me, by my foreign correspondent, and the manner of performing the
same, I wish it understood that I do not claim a single revolving spindle
