Office, No. 8, Southampton Buildings, Chancery Lane, in the County
of Middlesex, Civil Engineer, for the Invention of "IMPROVEMENTS
IN MACHINERY FOR ROVING AND SPINNING WOOL
OTHER FIBROUS
MATERIALS." A communication from abroad by Edwin Allen and Henry
Tatem Potter, both of Norwich, Connecticut, United States of America..
Sealed the 23rd July 1867, and dated the 26th January 1867.
PROVISIONAL SPECIFICATION left by the said George Haseltine at the
Office of the Commissioners of Patents, with his Petition, on the
26th January 1867.
I, GEORGE HASELTINE, of the "International Patent Office," No. 8,
Southampton Buildings, Chancery Lane, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN MACHINERY FOR ROVING AND SPINNING WOOL AND OTHER FIBBOUS MATERIALS,'
a communication, to be as follows:-
The first part of the said Invention consists in so constructing, arranging,
and operating the box or head which encloses the drawing rollers that the
said box may either be stationary as heretofore used, so as to give a fixed
tivist relatively to the draft of the sliver, or may be rotated either in the same
or in the opposite direction and at different velocities to the tube which
carries the said rollers, whereby the twist and draft relatively to each other
may be varied and adapted to all peculiarities of the fibre.

page_text: The second part of the said Invention consists in a peculiar combination
of devices for producing this varied action. The revolving twisting tube with
its drawing rollers is made to fit and rotate within a socket which forms part
of the box or head. The said box imparts the drawing motion to the rollers,
and is made capable of revolving either with or in the opposite direction
to the twisting tube by means of a worm wheel which gears with an endless
screw on the shaft employed to rotate the said head; this combination is
compact, simple, and readily admits of the parts being detached for the purposes
of cleaning or repairing, and also gives a positive motion to the head which
is free from "slip." The inlet tube which carries the drawing rollers is
made to rotate in a suitable bearing or bearings, and is provided at its end
with a pulley which is driven by a suitable belt from a driving pulley. The
outer or delivery tube which carries the box or head is formed with a screw
thread on its interior surface. The said screw thread fits into the teeth of
the rollers, and imparts to the latter a revolving motion on their axes when
the inlet tube is rotated. In this way draft and twist are simultaneously
given to the sliver. In some cases the box or head may remain stationary,
the drawing rollers having a rotation on their own axes at a certain relative
velocity to their rotation with the inlet tube upon which they are carried.
To vary such relative velocity, to give more or less draft in proportion to
twist, the box or head is so arranged or hung that it may be rotated at a
different velocity to the tube which carries the drawing rollers, and either in
the same or in the opposite direction to the said tube. By this arrangement
the action of the screw thread formed in the box on the rollers, or of the
latter upon the said screw thread, may be regulated to the greatest nicety to
suit any description of fibre, by varying the motion of the rollers on their own
axes relatively to their rotation on the inlet tube. In arranging the devices
for giving to the box or head this variable character the outlet tube which
carries the said box or head is by preference fitted to rotate in a suitable
bearing, the outer end of the said box being provided with a pulley which
is driven by a belt from a drum fixed on a driving shaft. The latter carries
two loose pulley cones, one of which is connected by a cross belt and the
other by a straight belt with other pulley cones keyed fast on the shaft of
the pulley which drives the inlet tube. A clutch is fitted to slide upon a
feather on the shaft carrying the loose cones, and is operated by a lever so
as to throw the said clutch in gear with either one or other of the said loose
cones, which is thus made to revolve with the shaft and thereby impart to
the box or head a rotary motion, either in the same or in the opposite direction
to that of the inlet tube. The velocity of the box or head relatively to the

page_text: or near the
said tube is varied by changing the belts to different pulleys on the cones, or
the said box may be rendered stationary by adjusting the clutch midway
between the two loose cones, so that neither are in gear with the shaft.
The drawing and twisting head may be secured by a bracket to the frame
of a spinning machine, which frame will carry any desired number of such
heads. A tubular bearing or socket is connected with or forms part of the
said bracket, and serves to receive a socketed box or head, the said box or
head and bearing being made capable of rotating together. This box or
head has an interior spiral or screw thread preferably formed at
feed end, into which thread the teeth of the drawing rollers fit. This thread
serves to impart to the said rollers their drawing action as they are rotated
in common with the twisting tube which may be driven by a pulley.
Teeth of a spiral character are formed on the outside of the said socketed
head, preferably at or near the opposite end thereof to that in which the
spiral or screw threads are formed, into which teeth an endless screw gears.
The said screw projects through the shell or socket, and is rotated by a shaft
which may be driven by cone pulleys furnished with a suitable reverseing
motion to vary the velocity and direction of motion of the said screw
relatively to the twisting tube.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Haseltine in the Great Seal Patent Office on the
26th July 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," No. 8, Southampton Buildings,
Chancery Lane, in the County of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of January, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said George Haseltine, Her special licence that I, the said George Haseltine,
my executors, administrators, and assigns, or such others as I, the said
George Haseltine, 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 "IMPROVEMENTS

page_text: N MACHINERY FOR ROVING AND SPINNING WOOL AND OTHER FIBROUS MATERIALS,"
upon the condition (amongst others) that I, the said George Haseltine, 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
perforined, 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 George Haseltine, 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, reference being had to the accompanying Sheet of Drawings
forming a part of this Specification :-
The first part of this Invention consists in so constructing, arranging, and
operating the screw head or box that the said screw head may either be
stationary as heretofore used, so as to give a certain unvarying twist to the
sliver relatively to the draft, or may be rotated either in the same or in an
opposite direction to the tube which carries the drawing rollers and at
different velocities, whereby the twist and draft relatively to each other may
be more or less varied and adjusted to meet the peculiarities of the different
libres.
The second part of the said Invention consists in a peculiar combination of
devices for producing this varied action. The revolving twisting tube with its
drawing rollers is made to fit and rotate within a socket forming part of the
screw bead or box; the said screw head imparts the drawing motion to the
rollers, and is made capable of revolving in the same or in the opposite
direction to the twisting head by means of a worm wheel gearing with an
endless screw on the shaft employed to rotate the screw head. This com
bination is compact and simple, allowing the parts to be readily detached for
the purposes of cleaning or repairing, and giving a positive motion to the head
perfectly free from "slip." The said Invention, though applicable to the
spinning or roving of various fibrous materials, is more especially applicable to
machinery for working wool.
DESCRIPTION OF THE DRAWINGS.

page_text: or combination of details constituting the second part of this Invention;
Figure 4 represents the other end of the said device; Figure 5 is a section of
the same on the line y, y, Figure 3; Figure 6 represents the screw head
employed in the said device.
In Figures 1 and 2 of the Drawings, A is the inlet tube for the sliver.
which tube carries the drawing rollers b, and is caused to rotate in the
bearing a by pulleys B, C, and belt D. The outer or delivery tube E,
carrying the roller box or head F, is formed with the spiral projections or
screw threads C on its interior surface; these threads gear into the toothed
rollers b, and cause the latter to revolve on their axes when the inlet tube A.
is rotated; in this way draft and twist are simultaneously given to the
sliver. The head F in some cases may be arranged to remain stationary, the
drawing rollers being caused to rotate on their own axes at a certain relative
velocity to their rotation with the tube by which they are carried, but to give
to the sliver more or less draft in proportion to its twist the relative velocities.
of the two motions of the rollers b must be varied; for this purpose the head F
is so arranged that it may be rotated at a different velocity to the tube A,
which carries the drawing rollers b, and may be driven either in the same or
in an opposite direction to that of the said tube. By this arrangement the
action of the screw thread c on the rollers b, or that of the latter on the said
screw thread will be increased or diminished, and the relative velocity of the
said rollers on their axes to that of the motion of the tubes A may be regu-
lated to the greatest nicety to suit the peculiarities of fibres of all descriptions.
The devices for giving to the bead F this variable motion may be varied, but
the arrangement represented may be advantageously employed for this purpose.
The outlet tube E which carries the head or box F is fitted to turn freely in
a suitable bearing a²; the outer end of the said box carries a pulley G, which
is driven by a belt d from a drum H on the shaft I; the latter carries two
loose cone pulleys J, J', which, as shown in Figure 1, are arranged with
their large and small diameters in opposite directions; one of these cones is
driven by a cross belt e, and the other by a straight belt f from the cones
K, K', on the shaft L, which carries the pulley C. A clutch M is fitted to
slide endwise on the shaft I, a feather 9 being provided to keep the said clutch
radially in position, and to cause it to turn with the said shaft; the said
clutch is operated by a lever N, and may be caused thereby to take hold of
either of the loose cones J, J', and hold the same in gear with the shaft I;
by this means rotary motion is imparted to the bead F either in the same or:
opposite direction to that of the inlet tube A. The velocity of the head F
relatively to the tube A is varied by changing the belts to the different pulleys.

page_text: of the cones J, K, or J', K', or by adjusting the clutch M midway between
the cones J, J', so that neither of the latter are caused to rotate with the
shaft I, the screw head F being in this case caused to remain stationary.
In Figures 3, 4, 5, and 6, A¹ is a bracket for supporting the drawing and
twisting head, the said bracket being secured to the frame of a spinning
machine which can be made to carry any desired number of such heads;
B is a tubular bearing or socket connected with or forming part of the said
bracket, and serving to receive the socket of a screw head C'; the said screw
head has interior spiral projections or threads c¹ formed, preferably at or near
the feed end, and the toothed drawing rollers gear into these threads which
impart to the said rollers a drawing action as they are rotated with the
twisting tube D', the latter being driven by means of a pulley d¹. The screw
head C is provided with teeth e', preferably arranged at or near the opposite
end to that whereon the spiral threads c are formed; these teeth are inclined
and pitched to correspond with those of the endless screw or worm E¹, which
gears into the said teeth. The worm E¹ projects through the shell or socket B',
and is rotated by a shaft F1, which may be driven by cone pulleys furnished
with a suitable reverse motion to vary its velocity and direction relatively to
those of the twisting tube D'.
By this combination of devices it will be obvious that on failing to give
motion to the shaft F¹ the twisting tube D¹ and drawing rollers b¹ will, as in
the modification represented in Figures 1 and 2, have a certain unvarying
relative velocity the one to the other, thereby giving a certain draft in
relation to the twist, but on giving the shaft F¹ a fast or slow motion the
screw or worm E will rotate the screw head C either in the same or in an
opposite direction to that of the tube D' accordingly as more or less draft
is required in relation to the twist; the screw head C¹ in revolving will also,
as in the first-described arrangement, produce such changed or variable action
on the drawing rollers. The connection of the shaft F¹ with the screw
bead C¹ by means of the worm E' and teeth e¹ being a positive one, there will
be no tendency to slip in starting or in altering the velocity or direction of
motion of the screw head, while the combination, as described, is not only
simple and compact, but readily admits of the parts being detached for
cleaning or repairing.
Having thus fully described the said Invention, as communicated to me by
my foreign correspondents, and shown how the same may be conveniently and
advantageously carried into practice, I claim,-
First, the combination of the inlet tube A, drawing rollers b, and head F,
with its spiral or screw thread c when the said head is arranged for operation

page_text: in connection with suitable gearing so that it may be rotated in the same or
in an opposite direction to that of the inlet tube A for varying the twist in
relation to the draft of the sliver, substantially as set forth.
Second, the twisting tube D' and drawing rollers b', socketed screw head C',
and worm or screw E', combined and operating together, substantially as and
for the purposes set forth.
In witness whereof, I, the said George Haseltine, have hereunto set my
hand and seal, this Twenty-fifth day of July, in the year of our Lord
One thousand eight hundred and sixty-seven.
