"
Scaled the 24th July 1855, and dated the 7th February 1855.
PROVISIONAL SPECIFICATION left by the said William Warbrick and
John Walker at the Office of the Commissioners of Patents, with their
Petition, on the 7th February 1855.
We, WILLIAM WARDRICK, of Dukinfield, Machine Maker, and JonN
WALKER, of Compstall Bridge, near Stockport, Mechanic, both in the County
of Chester, do hereby declare the nature of the said Invention for "CERTAIN
IMPROVEMENTS IN MACHINES FOR PREPARING, SPINNING, DOUBLING, WARPING AND
DRESSING COTTON, WOOL, AND OTHER FIBROUS SUBSTANCES," to be as follows:-
Our Invention, in the first place, relates to arrangements of mechanism for
traversing the slivers to be operated upon by the drawing rollers of those
machines for preparing fibrous materials for spinning of the class known as
slubbing or roving frames, and these machines for spinning fibrous materials
of the class known as "throstles" or "mules," the purpose of which traversing

page_text: of the slivers is to prevent the too rapid destruction or deterioration of the
surface of the rollers (especially the covered ones,) which would result if the
slivers passed through the rollers at one point, and were operated upon by
one part of the drawing rollers only; our improvements having for their object
the more effectual traversing of the slivers over the surface of the rollers than
has been hitherto accomplished, and tho obtainment, cousequently, of a more
effective action and even weaving of the drawing rollers, and an economy in
the cost of renewal.
Our improvements consist in the application, adaptation, and arrangement
of a cam (shaped to produce an uniform reciprocating action) at one end of
the frame, which acts against a pin or friction bowl, attached to the traverse
bar (which guides the slivers to the rollers), or against a lever in connection
with the traverse bar. The cams here referred to may be such as give their
action either in a direction parallel with, or in a direction radiating from, their
axes of rotation. We prefer to use such as are double action, namely, those
which act to produce the reciprocations in both directions; but for single-action
cams we use a weight or weighted lover to keep the friction bowl or pin (attached
to or in connection with the traverse bar) against the face or path of the cam.
Our Invention refers, in the second place, to machines for warping, dressing,
or sizcing, and relates to traversing or spreading the threads as they are wound
upon the beams in those machines, so that a greater quantity may be laid
upon them; and it consists in the application and adaptation of mechanism,
similar to that referred to in the first part of our Invention, to traverse the
reed or bar which conducts the threads (corresponding to the traversing bar
referred to in the first part of our Invention for guiding the slivers), with an
addition of an arrangement, whereby the extent of the traverse is shortened
as the beam increases in diameter after it is filled to-the level of the flanges,
so as to shape the ends of the beam in the conic form.
by the said William Warbrick and John Walker in the Great Seal Patent
Office on the 3rd August 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
WARBRICK, of Dukinfield, Machine Maker, and JonN WALKER, of Compstall
Bridge, near Stockport, Mechanic, both in the County of Chester, send
greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh February, in the year of our Lord One
thousand eight hundred and fifty-five, in the eighteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the
said William Warbrick and John Walker, Her especial licence, that we,
the said William Warbrick and John Walker, our executors, administrators,
and assigns, or such others as we, the said William Warbrick and John
Walker, our 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 " CERTAIN IMPROVEMENTS IN MACHINES
FOR PREPARING, SPINNING, DOUBLING, WARPING, AND DRESSING COTTON, WOOL, AND
OTHER FIBROUS SUBSTANCES," upon the condition, amongst others, that we, the
said William Warbrick and John Walker, 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 William Warbrick and John Walker,
do hereby declare the nature of our said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement and accompanying Drawings (that is to say) :-
Our Invention, in the first place, relates to arrangements of mechanism for
traversing the slivers to be operated upon by the drawing rollers of those
machines for preparing fibrous materials for spinning of the class known as
slubbing or roving frames, and those machines for spinning fibrous materials
of the class known as "throstles" or "mules," and those machines for doubling
threads known as doubling frames, the purpose of which traversing of the
slivers or threads is to prevent the too rapid destruction or deterioration of
the surface of the rollers (especially the covered ones), which would result if the
slivers passed through the rollers at one point, and were operated upon by one
part of the drawing rollers only; our improvements having for their object
the more effectual traversing of the slivers over the surface of the rollers than
has been hitherto accomplished, and the obtainment, consequently, of a more
effective action and even wearing of the rollers, as well as an economy in the
cost of renewal.
Our improvements consist in the application, adaptation, and arrangement
of a cam (shaped to produce a uniform 'reciprocating action) at one end of the

page_text: machines, herein-before mentioned, which is made to act against n pin or
anti-friction bowl attached to the traverse bar (which guides the slivers to the
rollers), or against a lever in connection with the traverse bar. The cams
here referred to may be such as give their action either in a direction parallel
with, or in a direction radiating from, their axis of rotation. We prefer to uso
such as are double action, namely, those which act to produce the required
reciprocations in both directions; but for single-action cams we use a weight
or weighted lever to keep the friction bowl or pin (attached to or in connection
with the traverse bar) against the face of the can. The Sheet of Drawing
annexed hereto exhibits the arrangements referred unto. Fig. 1 is a plan,
Fig. 2 a back, and Fig. 3 an end, elevation of one modification. a, b, and c
represent, respectively. the front, middle, and back bottom rollers, and a', b', c',
respectively, the top rollers of a throstle spinning frame; is a worm on the
bottom back roller, which geers with a worm wheel c', cast on one side of a
double-action cam d (tho action of which is parallel to its axis); the other side
of this cam is formed in a separate piece, but is keyed on the same axis
ns that with the worm wheel (c) cast to it. The axis of the cam is held in a
frame, formed of two parts & and e', the latter being fixed to the former by a
screw. A stud (f) is screwed on a slotted part projecting from the part of
the frame e, upon which a lover g is free to oscillate. This lever on one arm
has a stud fixed in it that carries a friction bowl (9'), which takes into the
cam path, the shape of which is shewn by the Diagram Fig. 4. In the end
of the other arm of the lever ga stud is also fixed, forming the joint of a
piece h, connected with the end of the traverse bar h'. If the lower side of
the cam (d) is removed, it will only be single acting; in this case we apply
another arm and weight to the lever f, as shewn in dotted line, Figure 2.
Figures 5, 6, and 7 are, respectively, views corresponding to Figures 1, 2, and 3,
and shew another modification where a double-action cam is used, the action
of which is in a direction radiating from its axis. c, worm on the back bottom
roller c; c', worm wheel, having formed on the upper face of it a cam path
or projection d, shaped to give an action corresponding to that shewn in the
Diagram Figure 4. It is free to revolve on a vertical stud c, screwed in the
roller beam, or in a bracket fixed to the framing. A piece fixed to the end of
the traverse bar h' is made to take hold of the cam projection or path d, as
shown, and sido action of the piece is prevented by the end of the stud e,
which passes through a slot made in it. Two studs may be fixed in the end of
the piece to carry anti-friction bowls, one to take on each side of the cam
projection or path. The general arrangement of the rollers of preparing,
spinning, and doubling machines vary but little; therefore the manner of

page_text: applying this part of our Invention to one of those machines will sufficiently
explain the manner of applying it to all of them.
Our Invention, in the second place, refers to machines for warping (on beams),
dressing, or sizeing, and relates to a mode of traversing or spreading the threads
as wound upon the beams of such machines, so that a greater quantity may
be laid upon them; and it consists in the application and adaptation of
mechanism, similar to that referred unto the first part of our Invention, to
traverse the reed or bar which conducts the threads (corresponding to the
traverse bar, referred to in the first part of our Invention for guiding the
slivers,) with an addition of an arrangement, whereby the extent of the traverse
is shortened as the beam increases in diameter after it is filled to the level of
the flanges, so as to shape the ends of the beams in the conic form. The
arrangement above referred to is exhibited in Figures 8, 9, and 10, which are
respectively, plan, front, and side elevations, shewing its application to warping
or sizeing machines where the beam is revolved to wind on the thread by a cone
motion. A worm is fixed on the shaft of the driven cone A, which geers
with a worm wheel c³ on an upright shaft d, free in bearings formed in a
bracket e, which is attached to the side frame of the machine.
On the upper
end of the shaft & a drum cam d is keyed, which acts on a friction bowl,
carried on an arm g, which is keyed on the end of a short shaft g', free to
oscillate in a bearing formed in a part from the bracket c. On the other end
of the short shaft g' another arm g² is keyed, having a long slot in it; into
this slot a pin k¹ takes, which is fixed in a lever k, having its fulcrum at k²,
which lever is connected with the bar h', through the teeth in which the threads
pass in going to the beam B. By these arrangements it will be seen that the
reciprocations produced by the cam will be imparted to the bar h', and so traverse
the threads upon the beam B. The arrangements to diminish the traverse of
the bar when the beam is filled to the level of the flanges B', and as it increases
above it, are as follows:-The fulcrum of the lever is jointed to an arm m,
keyed on the end of a short shaft m', that is free to oscillate in a fixing n,
secured to the floor, the other end of the shaft m' having keyed upon it another
arm m, upon which an anti-friction bowl m³ is fitted to slide backwards and
forwards, as shewn, being fixed by a set screw m². While the beam is filling
below the level of its flanges the lever m rests on a part from the bracket e, so
that while in that position the reciprocations of the traverse bar are of uniform
length, but when full to the level of the flanges, the yarn comes against the
anti-friction bowl (m³), which causes the arm (m) to lift the fulcrum of the
lever (k) (as the beam increases in diameter), which it is at liberty to do, as
the pin fixed in the lever k can rise in slot in the arm g, and as a slot is

page_text: formed at the upper end of the lever k, in which the pin in the traverse bar
takes, and thus the reciprocations of the traverse bar will be diminished as the
beam increases in diameter after it has attained the diameter of its flanges.
The largest amount of traverse given to the bar h' during the time that the
beam is filling to the level of its flanges may be regulated by increasing or
diminishing the action of the cam, or proportioning the lengths of the arins
or levers g, k, but most readily by adjusting the pin k' in the slot of the lever
k, and the least amount of traverse given to the bar h' (when the beam is full)
may be regulated by adjusting the anti-friction bowl m³ on the arin m². In
applying this modification to machines in which the beam is revolved to wind
on the threads by contact with a drum or cylinder, the shaft & may be driven
from the shaft of the drum or cylinder, and the fulcrum of the lever k may be
raised after the beam is filled to the level of the flanges by the rising motion
of the axis of the beam.
We have now particularly described the nature of our luvention, and the
manner in which it may be carried into effect, and claim the application,
adaptation, and arrangement of double-action cams for traversing the slivers
or threads between the rollers of preparing, spinning, or doubling machines.
We also claim single-action cams, weighted as herein-before described in tho
first part of our Invention. We claim the application and adaptation of the
mechanism in the manner and for the purpose described in the second part of
our Invention.
In witness whereof, I, the said William Warbrick, on behalf of myself
and of the said John Walker, have hereunto set my hand and seal,
the First day of August, in the year of our Lord One thousand eight
hundred and fifty-five.
WILLIAM WARBRICK. (L.8.)
