in the County of Middlesex, for the Invention of AN IMPROVEMENT IN
COP TUBES FOR MULE AND OTHER SPINDLES, AND MACHINERY FOR MAKING
SUCH COP TURES. "A communication
Sealed the 4th August 1854, and dated the 2nd June 1854.
PROVISIONAL SPECIFICATION left by the said Moses Poole at the Office
of the Commissioners of Patents, with his Petition, on the 2nd June
1854.
1, MOSES POOLE, of the Avenue Road, Regent's Park, in the County of
Middlesex, do hereby declare the nature of the Invention for "AN IMPROVE-
MENT IN COP TUBES FOR MULE AND OTHER SPINDLES, AND MACHINERY FOR MAKING
SUCH COP TUBES," to be as follows:-
This Invention has for its object the use of metal cop tubes to receive the
foundations of cops, in place of the paper quills" heretofore employed, and
machinery for making such metal cop tubes. For this purpose sheet metal
conical tubes are employed, and it is preferred to make them in the following
manner, and although other sheet metal may be employed it is preferred to use
tinned sheet iron:-The machinery is arranged with a mandril or die of the
interior form of the intended cop tube, and two concave dies are employed,
which, on coming together, coincide with the exterior of the cop tube. The
parts of the machine are put in motion by a shaft or axis and cams. Each
cop tube is made with a projecting flanch at its larger end. The concave dies

page_text: are caused to slide by cams, so as to come into action in succession; one of
them has two cutting edges, which, together with two fixed cutters, cut the
sheet metal (as it is fed into the machine) to the proper size. By the sliding
of the first concave die the cutting is accomplished, and the metal is bent
partly round the mandril. The second concave die then causes the two edges
of the metal, while still held by the other die and mandril, to be inclined
towards each other, and by its continued motion it completes the bending of
the metal round the mandril. In order to produce a flanel, the mandril is
formed with a shoulder, by which it bends over the larger end of the tube so
as to form a flanch, the parts go back, the tube is forced off the mandril, and
the machine is, by the simple rotation of its axis, again in a position to make
another tube suitable for a cop-tube.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Moses Poole in the Great Seal Patent Office on the 23rd
August 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MOSES
POOLE, of the Avenue Road, Regent's Park, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of June, in the year of our Lord One
thousand eight hundred and fifty-four, In the seventeenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Moses Poole, Her special licence that I, the said Moses l'oole, my executors,
administrators, and assigns, or such others as I, the said Moses Poole, 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 "AN IMPROVEMENT IN COP TUBES FOR MULE AND
OTHER SPINDLES, AND MACHINERY FOR MAKING SUCH COP TUBES," communicated to
me from abroad, upon the condition (amongst others) that I, the said Moses
Poole, by an instrument in writing under my hand and seal, 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.

page_text: NOW KNOW YE, that I, the said Moses Poole, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
thereof (that is to say):-
The nature of the Invention consists in the use of a metallic "cop tube"
upon mule and other spindles to receive the foundation of the "cop," in place
of the paper quill" heretofore employed for the purpose, and also in a pecu-
liarly constructed machine for making the same. And I hereby declare the
following to be a full, clear, and exact description of both branches of the..
Invention, reference being had to the annexed Drawings, making part of this
Specification, in which Figure 1 is a plan of the machine; Figure 2, a side
elevation, a portion of the framework being removed to show the parts within;
Figure 3, an end view; Figure 4, a plan of the dies and cutters, the spindle
round which the tube is formed being seen in section; Figure 5, a vertical
section through the spindle and dies; Figure 6, a plan of the dies closed upon
the spindle, the tube being seen round the latter; Figure 7, a plan of the dies
partially closed, showing the manner in which the blank receives its prelimi-
nary bending previous to the closing of the dies; Figure 8, an end view of
the die S; Figure 9, an end view of the die R; Figure 10, an end view of
one of the cutters d; Figure 11, a view of one of the sheet metal blanks of
which the tube is formed; Figure 12, the complete tube; Figure 13, the
frame or yoke which carries the roller, against which the cams bear which
move the carriage back; Figure 14, a section through the spindle and sleeve.
for throwing off the tube, half size; Figure 15 is the cam which throws off the
tube.
The metallic tube or quill which I make use of is represented of full size in
Figure 12. It consists of a conical tube of tinned iron or other suitable sheet
metal, having a flange a² at its upper end. This tube is placed over the spindle
and receives the foundation of the cop, entirely replacing the paper quill here-
tofore in use.
I will first enumerate the separate steps of the process of forming the tube,
then describe the several parts of the machine employed in making the same,
and, lastly, the operation of the complete machine.
The metal usually employed in the manufacture of these tubes is tinned
sheet iron. This is preferred on account of its cheapness and peculiar adap-
tation to the work; other metals, such as sheet zinc, copper, &c. might, under
certain circumstances, be employed for the purpose; the tinned iron, however,
is that which is preferred.
The sheet metal is first cut into strips of a width slightly greater than the

page_text: length of the finished tube, in order to allow sufficient metal for the formation
of the flange a (Figure 12), as will be hereafter explained. The strips of
metal thus produced are then fed into the machine, successive portions being
cut off of the form represented in Figure 11. These portions are then bent
round a suitably formed spindle, the form of the
which are immediately brought to bear upon it.
pressing or forming dies, the spindle round which the tube has been formed is
slightly depressed for the purpose of forming the flange a² (Figure 12), and
..the perfect tube is ejected from the machine preparatory to recommencing the
operation.

While thus held in the com-
In the Drawings, A is the framework of the machine; B, the driving shaft,
which is supported upon the arms C, and is actuated by power communicated
through the pullies D, D'. Upon the end of the shaft B is a bevil gear E,
which engages with a similar gear F upon the inclined shaft G, carrying
another bevil gear H, which engages with the bevil gear 1 upon the trans-
verse shaft K. Q is a similar shaft at the other end of the machine, which
receives its motion from the shaft K through the gears L, M, N, O, and inter-
mediate shaft P. The feed which introduces the material to the machine is
not represented, as any ordinary feed may be used for the purpose.
In Figure 4 are represented the dies by which the tube is formed; they are
so constructed with relation to each other, that when closed as seen in Figure 6,
the points a of the die R shall enter the recesses of the die S, and there shall
then be left a cylindrical space between them of a size just sufficient to accom-
modate the spindle c with the tube around it, as seen in red in the various
Figures. d, d, are the stationary cutters, between which play the moveable
cutters e, e. The cutters d,d, are suitably secured to the frame of the
machine; being set a little in advance of d, that the blank may be steadied
between the compressing die f and the spindle, before it is entirely separated
from the strip. These cutting portions of the dies are raised slightly above the
centre portions, as seen in Figure 8, as the blank must be cut slightly longer.
than the complete tube, for reasons to be hereafter more fully explained. At
the bottom of the dies S and R, around the semicircular portion f, y, is a
slight offset or projection 9, of a width equal to the thickness of the sheet
metal of which the tube is formed, the object of which is to support and hold
up the latter while the flange a is being formed, as will be hereafter
explained. These compound cutters and dies are operated as follows:-T, 1,
are carriages which receive a slight longitudinal motion upon ways attached to
the framework of the machine, in the following manner :-h, h', are rollers
attached to the sliding carriages T, T; W, W, are cams upon the shafts K, Q,

page_text: which impinge upon the rollers h, h', and close the dies, as seen in Figures 2
and 6. A', A, Figure 2, are yokes or frames projecting from the car-
riages T, T', which carry the friction rollers c', against which the cams B¹
upon the transverse shafts K and Q impinge, and thus the carriages are
retracted.
The dies S and R are secured to these carriages in the following manner
(Figures 1 and 2):-C are side supports, between which the dies are placed,
and by which they are held firmly; i, i, are ears which rise from these supports,
in which are pivoted the cams f', having the handles g' attached. These
cams are made to pass centre by depressing the handles g', and the dies are.
thus secured firmly to their carriages, their position longitudinally being ad-
justed by the screws h², as seen in Figures 1 and 2. The spindle around
which the tube is formed is constructed and operated as follows:-U is the
spindle, the lower portion c of which is of the exact size of the interior.
dimensions of the tube; immediately above this portion is the shoulder
which forms the flange a', as will be hereafter explained. Above the portion
of the spindle is a second shoulder l, the object of which is to limit the,.
upward motion of the sleeve or collar.m. At the completion of the operation
of forming a tube, this collar is depressed by means which will be hereafter
referred to, for the purpose of throwing off the finished tube. The spindle U
is attached by set screws n, o, to the socket p of the carriage E', which slides
up and down upon the ways F', secured to the arms C; this carriage is
depressed at the required instant for the purpose of forming the flange of
the tube by the cam q, in a manner which will be readily understood by an
inspection of Figure 3, and is raised by the cam r', which impinges upon the
roller t', projecting from the side of the frame m' on the top of the carriage
E' It now remains only to show the manner in which the collar m is
depressed for the purpose of throwing off the finished tube. p' is a fork
attached to the vertical rod q', and embracing the collar m.
attached to the rod q', and carrying the roller n', against which
impinges, by which means, as the latter revolves, the rod q' is raised, and the
collar m is brought up into position, as seen in Figures 2 and 5. As the
shaft B revolves, the collar m is permitted to drop, or is forced down by
the cam t, as will be readily seen on inspection of Figure 15.

The sheet metal being cut into strips of a suitable width, is fed into the
machine, as seen in red in Figure 4. The cutter S is then caused to advance
in the manner already explained. The advanced edge of the strip is first
trimmed between the cutters e', d', and the metal is then caught and steadied
between the die S and the spindle; the next instant a blank is severed from

page_text: the strip by the cutters e, d, all these cutters being suitably inclined, as seen in.

the blank. The feed is allowed slightly to exceed what is absolutely required.
for the tube, in order to ensure a clean cut up upon each of its side edges.
The instant after the blank is cut off it is bent round the spindle by the semi-
circular portion of the die S, as seen in red in Figure 7. To prevent the
spindle from being bent out of its true position by the pressure of this die, it.
may be made to rest against a supporting piece which bears against it, just
above the point where the dies embrace it, and prevents it from being deflected
out of the vertical. The next instant the opposite die R is brought up by the
cam W', impinging upon the roller h', and the edges a of the blank, Figure 7,
coming in contact with the inclined surfaces, , of the die R, are deflected
inwards, and as the dies are finally brought together, as in Figure 6, the edges
of the blank are brought together. It now remains to complete the tube by
forming the flange a². This is accomplished by the shoulder ¹ upon the
spindle, as the latter descends, in the following manner :-The dies having
closed upon the blank, the latter rests upon the projection g, which, as before,
explained, is of a width just sufficient to retain the tube from passing
through the dies. The cam 7, upon the main shaft B, now causes the
spindle to descend slightly for the purpose of forming the flange a, which
is bent over between the shoulder ', upon the spindle and the top of the
dies. The tube is now completed, and the dies open by the return motion
of the carriage; the cam t, Figures 3 and 15, now depresses the sleeve m,
and the finished tube is. thrown off. The operation then continues as
before....
Having thus described the nature of the said Invention and the manner of
performing the same, I would have it. understood that what I claim as the
Invention, and desire to secure by Letters Patent is, the employment of cop
tubes upon
mule and other spindles, to receive the foundation of the cop in.
place of the paper or other quill heretofore in use for the purpose, the same.
being manufactured out of sheet metal, substantially in the manner herein.
described.
Second, I claim the combination of cutting dies, bending dies, flange dies,
and spindle, or their equivalents, in an automatic machine, for the purpose of
making cop tubes, constructed and operating in the manner substantially as set
forth...
Third, I claim the combination of the bending dies, constructed and opera-
ting as herein-before. described, with the spindle, in the manner and for the
purpose set forth.

page_text: Fourth, I claim the projection or step g, upon the dies S and R, in com-
bination with the shoulder i, upon the spindle, for the purpose of forming the
flange of the tube a², as set forth.
In witness whereof, I, the said Moses Poole, have hereunto set my
hand and seal, this Twenty-sixth day of June, in the year of our
Lord One thousand cight hundred and fifty-four.
