Manager, for an Invention of "Improvements in MACHINERY OR APPARATUS
FOR PREPARING COTTON AND OTHER FIBROUS MATERIALS FOR SPINNING."
PROVISIONAL SPECIFICATION left by the said James Higgins and Thomas
Schofield Whitworth at the Office of the Commissioners of Patents on the
22nd July 1881.

JAMES HIGGINS, of Salford, in the County of Lancaster, Machine Maker, and
THOMAS SCHOFIELD WHITWORTH, of the same Place, Manager. IMPROVEMENTS
IN MACHINERY OR APPARATUS FOR PREPARING COTTON AND OTHER FIBROUS
MATERIALS FOR SPINNING."
Our Invention consists, firstly, in an arrangement for imparting a rising and
falling motion to the copping rails of slubbing and roving frames, whereby wo
are enabled to dispense with the racks and pinions ordinarily used for such
purposes.
For this object we provide a bar supported upon bowles or rollers carried by
the spring pieces of the frame, capable of being moved in a longitudinal direction.
Upon this bar we mount inclines acting upon bowles or rollers attached to brackets
sliding upon the spring pieces and which carry the copping rails. The aforesaid
bar we connect to the usual copping motion, and as it is traversed to and fro in the
direction of its length, the before named incline will cause the copping rails to be
raised or lowered.
The second part of our Invention consists in the arrangements we employ, by
which we are enabled to dispense with the usual weights used for counter-balancing
the copping rails of slubbing and roving frames.
«
For this purpose we divide the copping rail and its bobbin shaft or shafts into
two portions, one of which we cause to ascend while the other is descending, or
vice versa," using the weight of one portion to balance that of the other portion,
which we accomplish in the following manner :-)
-We mount the previously
described inclines in groups with their inclines placed in opposite directions, one
set of inclines acting upon one portion of the copping rail, the other set acting
upon the other portion, so that when the aforesaid bar carrying the inclines is
moved in the direction of its length, one portion of the copping rail will be caused
to ascend whilst the other descends.

page_text: Our Invention relates, thirdly, to a method of imparting motion to the bobbin
shafts of such slubbing and roving frames as have the copping rail divided into
two portions, as previously described under the second head of our Invention.
In such cases we use a supplementary shaft provided with a wheel gearing into
another connected with the differential motion (ordinarily used in slubbing and
roving frames), and from which it receives motion. The aforesaid supplementary
shaft we mount so as to be capable of rotating in bearings attached to the spring
pieces of the frame, the said supplementary shaft we place parallel to the bobbin
shaft or shafts, but not extending the entire length of the frame. To each end of
the aforesaid supplementary shaft and connected thereto by universal joints we
provide short lengths of shaft mounted, capable of rotating in bearings secured
to the copping rails, such shafts being provided at their outer ends with wheels
gearing into other wheels fast upon the bobbin shaft or shafts, so that as the
aforesaid bobbin shaft or shafts rise and fall with their respective copping rails,
motion will be imparted thereto.
The above described arrangement for imparting motion to the bobbin shafts of
slubbing and roving frames is also applicable to frames of ordinary construction
when the copping rail is not divided, but in such cases only one connection
need be made from the supplementary to the bobbin shaft.
In place of the before uamed wheels for connecting the above named
supplementary shaft to the bobbin shafts, we propose in some cases to use a chain,
the said chain passing around wheels, fast upon. and rotating with the
supplementary shaft, and also around wheels mounted upon the bobbin shaft or
shafts.
Another part of our Invention refers to a method of mounting the bevil
wheels upon the spindles of slubbing and roving frames by which the said spindles
are driven.
Upon the lower part of the spindle we form a square so as to pass into a
corresponding recess formed within the boss of the before named bevil wheel, an
extended portion of the said boss we form so as to fit upon a cylindrical part of
the spindle. The aforesaid bevil wheel is thus retained in position for being
driven, firstly, by the cylindrical portion of the spindle; and secondly, by resting
upon a part carrying the footstep of the spindle, such supporting part being
recessed so as to form a cavity for retaining a lubricant.
The next part of our Invention refers to the tube for supporting the spindles
of slubbing and roving frames, and consists in forming such tube and the footstep
upon which the spindle rests-in-one piece.
For this purpose we form the part connecting the footstep with the tube, as
a bridge piece within which we place the bevil wheel by which the spindle
is driven, such bevil wheel being secured to the aforesaid spindle in any desired
manner.
Another part of our Invention consists in a method of guiding and supporting
the tubes of slubbing and roving frames that carry the spindles thereof when such
tubes are in one piece, or substantially so, with the footstep as described under a
previous part of our Invention, and for simplicity of description we will consider
the aforesaid tube and step as one piece and call it "the tube." We form the
lower portion of the tube "barrel" shape, such barrel portion passing into a hole
formed in the "step rail," being retained therein by a set screw to prevent lateral
movement, but leaving the said tube free to oscillate upon the aforesaid “barrel
portion.
The upper portion of the aforesaid tube is supported by passing through holes
formed in the copping rail as the said copping rail rises and falls, any binding
action thereof upon the said tube being prevented by its oscillating upon the
previously mentioned barrelled portion.

as described under the previous part of our Invention; and for simplicity of

such barrel portion passing into a hole formed in the "step rail," being retained
therein by a set screw to prevent lateral movement, but leaving the said tube
free to oscillate upon the aforesaid "barrel" portion. The upper portion of
the aforesaid tube [is supported by passing through holes formed in the copping
rail as the said copping rail rises and falls, any binding action thereof upon
the said tube being prevented by its oscillating upon the previously mentioned
barrelled portion. In order that our Invention may be more readily understood
and carried into effect, we will now proceed to describe the same, reference being
made to the accompanying Drawings. The first part of our Invention is shewn by
Figs. 1, 2, and 3. Fig. 1 being a front elevation of so much of a roving
or slubbing frame as is requisite to .illustrate the application of our Invention.
Fig. 2 is a vertical cross section on the line A, B, of Fig. 1, looking in the direction
of the lefthand of the Drawing. Fig. 3 is a vertical cross section of Fig. 1 taken
upon the line C, D, and looking in the direction towards the right hand of the
Drawing, similar letters of reference being placed upon corresponding parts in each
of the Figures. At 4, 5, are the end frames of the slubbing or roving frame,
between which extends in a longitudinal direction the roller beam 6, supported at
intervals by the spring pieces 7, 8, 9, 10. Upon the spring pieces 7, 8, 9, 10 are
formed projecting brackets 11, 12,-13, 14, provided with-studs 15, 16, 17, 18,
carrying bowls 19, 20, 21, 22, capable of turning freely upon the said studs 15, 16,
17, 18. Resting upon the bowls 19, 20, 21, 22, is a rail or bar 23 extending in
the direction of the length of the frame, and capable of being traversed to and fro
lengthwise upon the bowls 19, 20, 21, 22. Carried upon the bar 23 are inclines 2+,
25, 26, 27, such inclines are formed with projecting parts bolted on the said bar 23.
Within the spring pieces 7, 8, 9, 10, are formed openings 28 (scen only in Figs. 2
and 3), through which openings the said inclines 24, 25, 26, 27, pass when the bar
23 is traversed in the direction of its length, as will be hereafter described, such
openings 28 serving as guides for maintaining the inclines 24, 25, 26, 27, and the
bar 23 in a vertical position. Upon the spring pieces 7, 8, 9, 10, are projecting
strips or ribs 29, which serve as vertical guides to brackets 30, secured to the
copping rail 36 by bolts. Upon the brackets 30 are formed projecting brackets 31
carrying studs upon which are bowls 32, 33, 34, 35, capable of rotating upon the
said studs. The bowls 32, 33, 34, 35, rest upon the upper surfaces of the inclines
24, 25, 26, 27, respectively, and serve to support the bobbin or copping rail 36. An
extension 31* of the brackets 31 passes below the inclines, so as to partially
embrace them, the purpose of which we shall hereafter point out. The longitudinal
bar 23 we connect in any suitable manner to the usual copping notion of the
slubbing or roving frame, so that such copping motion will cause the bar to be
traversed to and fro in the direction of its length, such to and fro motion of the

page_text: bar 23 causes the copping rail 36 to be raised and lowered as follows:-Supposing
that the bar 23 with the inclines 24, 25, 26, 27, is being traversed in the direction
of the arrow E, the inclines 24, 25, 26, 27, acting upon the bowls 32, 33, 34, 35,
will cause the copping rail 36 to be elevated, but when the bar 23 and the inclines
24, 25, 26, 27, are traversed in a direction opposite to that of the arrow E, the
copping rail will be allowed to descend as the incline 24, 25, 26, 27, recede
from the bowls 32, 33, 34, 35. By the copping motion of the roving or slubbing
frame acting upon the bar 23, so as to traverse it a greater or less degree
the building of the slubbing or roving upon the bobbin is effected. If the
bobbin or copping rail 36 should from any cause not descend when the inclines
are receding the underside of the inclines 24, 25, 26, 27, acting against
the projecting parts 31* of the brackets 31 will cause the copping rail 30
to be drawn downward. To the spring piece 10 is secured a stud 37 upon
which, and turning freely thereon, is a grooved pulley 38. Passing over this
pulley 38 and partially round a pulley 39 turning loosely upon a stud
carried by the spring piece 10 is a chain 40, one end thereof being secured to a
stud or bracket 41 attached to the bar 23, the other end of the chain 40 being
provided with a weight 42, such weight 42 tending to draw the bar 23 in the
direction of the arrow E acts as a counterpoise or balance weight to the copping
rail 36, the weight of which tends to force the inclines 24, 25, 26, 27, and the
bar 23 in a direction opposite to that in which the weight 42 acts upon the bar 23.
The second part of our Invention is shewn by Figs. 4 and 5, Fig. 4 being a front
elevation of a sufficient portion of a roving or slubbing frame as is requisite to
illustrate our Invention. Fig. 5 is an end view of Fig. 4 when looking in the
direction of the left hand of Fig. 4. At 43, 44, are the end frames of a slubbing
or roving frame, between which extends in a longitudinal direction the roller
beam 44 supported at intervals by the spring pieces 45. Upon the spring pieces
45, 45, 45**, are formed projecting brackets 46 provided with studs or pins upon,
which and capable of turning freely thereon are bowls 47; upon the circumference
of the bowls 47 and supported thereby is a bar 48. At 49, 50, are inclines carried
by the bar 48, and secured thereto by means of bolts. At 51, 52, are the copping
or bobbin rails. As both of the copping rails are similar in construction we shall
apply similar letters of reference to cach portion, and distinguish them by the
addition of an asterisk (*). Upon the spring pieces 45*, 45**, are formed projecting
ribs 53, upon which slide brackets 54 attached to the copping rails 51, 52, such
ribs 53 acting as vertical guides to the copping rails 51, 52. Formed upon the
brackets 54, 54*, are brackets 55, 55*, provided with studs, such studs carrying
bowls 56, 56*, free to turn thereon, such bowls resting upon the inclines 49, 50, by
which the copping rails 51, 52, are supported. The bar 48 we connect to the usual
"copping motion" in any convenient manner so as to cause it to be traversed to
and fro in the direction of its length, such traversing motion of the bar 48 will by
means of the inclines 49, 50, acting upon the bowls 50, 56*, cause the copping rails
51, 52, to be raised and lowered, but it will be seen by the Drawing that the
inclines 49 are placed in an opposite direction to the inclines 50, so that when the
bar 48 is being traversed in the direction of the arrow F placed thereon, the
inclines 49 acting through media of the bowls 56* will cause the copping rail 51
to ascend, but the inclines 50 being drawn from beneath the bowls 56 the copping
rail 52 will be allowed to descend, the weight of the copping rail 52 keeping the
bowls 56 in contact with the inclines 50 while such descent is taking place. A
continued traversing of the bar 48 will raise the copping rail 51 to its highest
position, and allow the copping rail 52 to descend to its lowest position. Upon
the bar 48 being traversed in a direction opposite to that of the arrow F, as
previously described, the incline 50 acting upon the bowls 56 will now cause the
copping rail 52 to ascend, and the incline 49 will allow the copping rail 51 to
descend. The traversing to and fro of the bar 48 being controlled by the usual
copping or shortening motion, the roving or slubbing will be wound upon the
bobbin in any ordinary manner. By placing the inclines 49, 50, in opposite

page_text: directions upon the bar 48, as shown, so as to cause one rail to ascend while the
other is descending, we thereby utilize the weight of the copping rail 52 to
counterbalance the weight of the other copping rail 51, thereby dispensing
with the weights usually employed for counterbalancing the copping rails of
slubbing and roving frames. Our Invention relates, thirdly, to a method of
imparting rotatory motion to the bobbin shafts of such slubbing and roving
frames as have their copping rail divided into two portions, as previously
described, and is illustrated by Figs. 4 and 5 previously referred to. At 57
is a shaft capable of being rotated in bearings carried by the spring pieces
45*, 45** Mounted fast upon the shaft 57 is a toothed wheel 58 gearing into
another wheel connected with the differential motion ordinarily used in slubbing
and roving frames) and from which it receives motion. The shaft 57 is prevented
from being moved in a longitudinal direction by the boss of the jaw 81 and the
boss of the wheel 58. At each end of the shaft 57 are shafts 59, 60, by which
rotatory motion is transmitted to the bobbin shafts of the copping rails 51, 52.
As the arrangements hereafter to be described by which rotatory motion is
transmitted from the shaft 57 to the bobbin shafts of the copping rails 51, 52,
are similar, we shall confine our description to one of such arrangements, and upon
the other we shall affix similar letters of reference with the addition of an
asterisk (*). Within a bracket 61 secured to the copping rail 52 and capable of
being rotated and slidden longitudinally therein is a short shaft 68, the outer end
of such shaft being supported by a cross bar 62 bolted to projecting parts 63
formed upon the bracket 61. Fast upon the shaft 68 is formed a jaw 71 embracing
a block 72, formed upon which are projecting studs 73 passing into apertures
formed within the jaw 71. Upon the shaft 68 and fast thereon is a toothed
wheel 64 gearing into a wheel 65 mounted fast upon one of the bobbin shafts 66,
this wheel 65 gearing into another wheel 67 mounted fast upon the other bobbin
shaft 66 carried by tlie bobbin rail 52. At the right hand end of the Drawing
the bobbin shafts 66, 66*, are carried by the bobbin rail 51. In cases where there
is only one line of spindles to be driven there will be one only of such bobbin
shafts aforesaid. Upon the shaft 59 is formed a jaw 74 embracing the block 72,
formed upon which are projecting studs 75 (one only of such studs being shewn
in the Drawing) passing into apertures formed within the jaw 74. Upon the end
of the shaft 59 opposite to that previously referred to is formed a jaw 76, embracing
a block 79 provided with studs 80 passing into apertures formed in the jaw 76.
The block 79 is also embraced by a jaw 81 (one side only of such jaw shewing in
the Drawing), the block 79 being provided with projecting studs 82 passing into
apertures formed in the jaws 81. Upon rotatory motion being imparted to the
shaft 57 through the toothed wheel 58, rotatory motion will be transmitted by
means of the jaw S1, studs 82, block 79, studs 80, and jaw 76 to the shaft 59, the
jaw 81, studs 82, block 79, studs 80, and jaw 76 forming what is well known as
a "Hook's joint;" such joint enables the shaft 59 to occupy an angular position
to the shaft 67, while at the same time it is being rotated thereby. The shaft 59
through media of the jaw 74, studs 75, blocks, 72, studs 73, and projecting
parts 71 imparts rotatory motion to the short shaft 68, which shaft through the
wheels 64, 65, 67, gives rotatory motion to the bobbin shafts by which the bobbins
are rotated. The parts 74, 75, 72, 73, 71, also constitute a "Hook's joint," as
before referred to, thereby enabling the shaft 59 to occupy an angular position
in relation to the shaft 68 while transmitting rotatory motion thereto. While
the copping rails 51, 52, are raised and lowered, as previously described, by the
movement of the bar 48, the axes of the shafts 59, 60, rise above and fall below
the axis of the shaft 57 from which the shafts 59, 60, receive rotatatory motion, the
"Hook's joints," as previously described, permitting such rising and falling of
the shafts 59, 60, to take place, and at the same time transmit rotatory motion
from the shaft 57 to the shafts 6S, 68*, and through means of the wheels 64, 65, 67, 5
impart motion to the bobbin shafts 66, 66*. As the ends of the shafts 59, 60, are
raised and lowered by the upward and downward motion of the copping rails 51, 52,

page_text: the shafts 68, 68*, will be caused to move longitudinally within the brackets 61, 61*,
and the cross bar 62, 62x, the wheels 64, 65, being made of sufficient breadth
to prevent their passing out of gear when the shaft CS is slidden longitudinally.
The arrangement, as above described, may also be applied for transmitting
motion to the bobbin shafts of other roving and slubbing frames, than those
having two copping rails as previously described, but in such cases it will be only.
necessary to employ one of the shafts 59, 60, for transmitting rotatory motion to the
bobbin shaft or shafts. In our Provisional Specification we proposed in some cases
to transmit rotatory motion from the shaft 68 to the bobbin shaft or shafts by means
of a chain, but finding the same to be of little practical advantage, we lay no claim
thereto. Another part of our Invention refers to a method of mounting the bevil
wheels upon the spindles of slubbing and roving frames, by which such spindles
are driven, and is illustrated by Fig. 6. The lower part of the spindle 90 is formed
square, as shewn by the flat surfaces 91 which constitute two sides of the squared
portion of the spindle. The lower part of the interior of the boss 92 of the bevil
wheel 93 by which the spindle is driven is formed square so as to fit upon the
squared portions 91 of the spindle 90, the remaining upper interior portion of the
boss 92 of the bevil wheel 93 is formed cylindrical, so as to fit upon the cylindrical
part of the spindle 90 immediately above the squared portion thereof. The lower
part of the boss 92 of the bevil wheel 93 rests upon the footstep 94, such footstep
being recessed so as to form an annular cavity for the purpose of retaining
any suitable lubricant. The bevil wheel 93 is driven by one of the ordinary
bevil wheels upon the spindle shaft ordinarily used for driving such spindles
aforesaid.
The bevil wheel 93 is retained in position for being driven, firstly, by a
cylindrical portion of the spindle 90; and, secondly, by the lower part of the
boss 92 resting upon the footstep 94. A further part of our Invention refers to
the tube for supporting the spindles of slubbing and roving frames. This portion
of our Invention is illustrated by Figure 6. At 95 is a tube within which and capable
of revolving freely therein is the spindle 90. Formed with the lower part of the
tube 95 is a bridge piece 96 formed in one with the part 94 which supports the
foot of the spindle 90; the tube 95, bridge piece 96, and part 94 supporting the
spindle, being formed in one piece by casting or otherwise. By this arrangement
we ensure the footstep 94 and the interior of the tube, within which the spindle 90
rotates, having the same axial line, thereby avoiding the binding action which
would otherwise arise should the axis of the tube 95 and the axis of the footstep
not be coincident. The tube 95, bridge piece 96, and part 94 we will consider as
one piece, and for convenience of, description we will call it the tube" 95. The
tube 95 we connect to the bobbin and spindle step rails of slubbing and roving
frames in the following manner :-
25
At 98 is the spindle step rail of a slubbing or roving frame, to which is attached a
bracket 98 secured to the rail 98 by a set screw 99. Within the bracket 98* is
formed a cylindrical aperture 100, within which passes the lower end of the
tube 95, a collar 101 being formed thereon serving to support the tube 95. Upon
the bracket 98*, the lower part of the tube 95 passing into the cylindrical aperture
formed in the bracket 98*, we form barrel shaped for a purpose to be hereafter
described. To the copping rail 103 is secured a bracket 104 by means of set
screws 105; within the bracket 104 is formed a cylindrical aperture, within which
is a bush 106 secured therein by a set screw. Through an opening formed within
the said bush passes the upper part of the tube 95, such bush sliding upward and
downward upon the tube 95 as the bobbin rail 103 ascends and descends, the
aperture within the bush being made of greater diameter at each end for a purpose
we will hereafter explain. If from any cause the bobbin rail 103 should not
ascend and descend in a perfectly perpendicular direction in relation to the
bracket 98*, the tube 95 will be carried out of its perpendicular, the barrel shape
of the lower part of the tube 95 and enlarged portions of the bush 106 previously
described, will permit the bobbin or copping rail to ascend and descend without a

page_text: binding action being produced upon the tube 95 by the bush 106. The set
screw 107 is screwed into the bracket 98*, the point of such set screw pressing
'into a recess formed in the lower part of the tube 94, but not binding upon the
said tube, but serves to prevent the tube 95 being carried upward by the action of
the bobbin or copping rail 103.
Having thus described and ascertained the nature of the said Invention and the
manner in which the same is to be performed, we desire it to be understood that
we claim as secured to us under the above in part recited Letters Patent,-
Firstly. Imparting a rising and falling motion to the copping rails of slubbing
and roving frames by means of inclines.
Secondly. Forming the copping rail of slubbing and roving frames in two
portions, which are caused to rise and fall by means of inclines, such inclines
causing one portion of the copping rail to ascend while the other descends,
substantially in the manner and for the purposes described in reference to Figures 4
and 5.
Thirdly. Transmitting rotatory motion from the differential wheels or equivalent
apparatus to the bobbin shaft or shafts of slubbing and roving frames by means of
shafts provided with "Hook's joints or other equivalent apparatus, substantially
as shown by Figures 4 and 5.
"
Fourthly. Forming the bosses of the bevil wheels mounted upon the spindles of
slubbing and roving frames with squared and cylindrical parts in the manner and
for the purposes described in reference to Figure 6.
Fifthly. Forming the tube and footstep for supporting the spindles of slubbing
and roving frames in one casting or piece, substantially in the manner and for the
purposes described and shewn in reference to Fig. 6.

to Fig. 6.
In witness whereof, I, the said James Higgins, have hereunto set my hand
and seal, this Eighteenth day of January, in the year of our Lord One
thousand eight hundred and eighty two.
