of Lancaster, Machinist, and Edmund Hartley, of the same Place,
Machinist, for the Invention of "IMPROVEMENTS IN SLUBBING AND ROVING
FRAMES, A MODIFICATION OF WHICH IS APPLICABLE TO WINDING AND THROSTLE
FRAMES"
Sealed the 29th January 1867, and dated the 20th August 1866.
PROVISIONAL SPECIFICATION left by the said Samuel Radcliffe Platt
and Edmund Hartley at the Office of the Commissioners of Patents, with
their Petition, on the 20th August 1866.
We, SAMUEL RADCLIFFE PLATT, of Oldham, in the County of Lancaster,
Machinist, and EDMUND HARTLEY, of the same Place, Machinist, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN SLUBBING AND
ROVING FRAMES, A MODIFICATION OF WHICH IS APPLICABLE TO WINDING AND
THROSTLE FRAMES," to be as follows:-
Our improvements relate to that portion of slubbing and roving frames by
which the lift is regulated and the copping motion is governed, and may be
performed in the manner following, that is to say; the upper cone shaft or
other shaft having similar continuous motion gives motion to an upright shaft

page_text: suitably placed and suspended in bearings in the framing. Upon two sliding
keys on this upright shaft is fitted a cone, being one-half of a friction clutch
box, so that it may receive rotary motion from and with this upright shaft,
and may be moved longitudinally thereon. This cone is actuated downwards
by its own gravity, its motion in this direction being assisted by an expanding
helical spring fixed at one end to a hoop on the shaft, and bearing against
the boss of the cone at the other. Loose upon the same shaft is fitted a long
socket, on the top of which is fastened a cone (the other half of a friction box
so made as to fit the half which rotates with the shaft. Through this half
there passes a loose pin which presses at one end against a circular plate
which has its face steeled or hardened, and is kept in position by a stud
fastened in it, which slides in a holo in the cone into which it fits easily; the
other end of the loose pin projects a short distance through the cone and rests
upon an oscillating plate having two inclines and stops so arranged upon its
surface that each oscillation of the plate releases the pin from one incline and
stop and sets it for the other. By this arrangement the cones are brought
into contact and revolve together for one-half of a revolution, and then are
separated by the action of the pin upon the inclines and stops. The oscil-
lation of this plate is produced by the lift of the frame, and is varied in time
at will by the adjusting of two screws which are specially provided and
adapted for that purpose. The time of oscillation is also affected by the
shortening motion common to most slubbing and roving frames; the socket
which thus intermits its rotation at each half revolution effects two sets of
changes. By means of an eccentric fastened upon it or cast with it it reverses
the copping motion; by two face or other cams suitably fastened on it it acts
to release and engage alternately the two catches by which the shortening of
the lift or traverse of the copping is permitted to be effected and its amount
regulated, and the strap is placed on the cones in a position suitable for
driving the bobbins at the velocity required by the next layer of slubbing or
roving.
We wish it to be understood that we do not confine ourselves to the special
forms in which this is set forth as different portions of the apparatus may be
varied.
The whole apparatus may be placed in a borizontal position instead of
vertical. The oscillating plate may have only one incline and stop, and
the cone be furnished with two pins. The cone shaft may make an
entire rotation, and effect its changes by proportional wheels.
The cams
used may be adapted in configuration to suit different methods of employing.
them.

the copping motion of winding frames and throstles, these being machines of
the same class.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel Radcliffe Platt and Edmund Hartley in the Great
Seal Patent Office on the 20th February 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, SAMUEL
RADCLIFFE PLATT, of Oldham, in the County of Lancaster, Machinist, and
EDMUND HARTLEY, of the same Place, Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of August, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Samuel Radcliffe Platt and Edmund Hartley, IIer special licence that we,
the said Samuel Radcliffe Platt and Edmund Hartley, our executors, adminis-
trators, and assigns, or such others as we, the said Samuel Radcliffe Platt and
Edmund Hartley, 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 "IMPROVEMENTS IN
SLUBBING AND ROVING FRAMES, A MODIFICATION OF WHICH IS APPLICABLE TO
WINDING AND THROSTLE FRAMES," upon the condition (amongst others) that
we, the said Samuel Radcliffe Platt and Edmund Hartley, our executors
or administrators, by an instrument in writing under our, or their, or ou
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
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 Samuel Radcliffe Platt and Edmund
Hartley, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement, that is to say :-
Our improvements relate to that portion of the slubbing and roving frames
by which the lift is regulated and the copping motion is governed, and may

page_text: be performed in the manner following, that is to say; the upper cone shaft
or other shaft having similar continuous motion gives motion to an upright
shaft suitably placed and suspended in bearings in the framing. Upon two
sliding keys on this upright shaft is fitted a cone, being one-half of a friction
clutch box, so that it may receive rotary motion from and with this upright
shaft, and may be moved longitudinally thereon. This cone is actuated down-
wards by its own gravity, its motion in this direction being assisted by an
expanding belical spring fixed at one end to a hoop on the shaft, and
bearing against the boss of the conc at the other. Loose upon the same
shaft is fitted a long socket, on the top of which is fastened a cone, the other
half of a friction clutch box so made as to fit the half which rotates with the
shaft. Through this half there passes a loose pin which presses at one end
against a circular plate which has its face steeled or hardened, and is kept in
position by a stud fastened in it which slides in a hole in the cone into which
it fits easily. The other end of the loose pin projects a short distance through
the cone, and rests upon an oscillating plate having two inclines and stops so
arranged upon its surface that each oscillation of the plate releases the pin
from one incline and stop and sets it for the other. By this arrangement the
cones are brought into contact and revolve together for one half of a revolution
and then are separated by the action of the pin upon the inclines and stops.
The oscillation of this plate is produced by the lift of the frame, and is varied
in time at will by the adjusting of two screws which are specially provided
and adapted for that purpose. The time of oscillation is also affected by the
shortening motion common to most slubbing and roving frames; the socket
which thus intermits its rotation at each half rovolution effects two sets of
changes. By means of an excentric fastened upon it or cast with it it reverses
the copping motion; by two face or other cams suitably fastened on it it acts
to release and engage alternately the two catches by which the shortening of
the lift or traverse of the copping is permitted to be effected and its amount
regulated, and the strap is placed on the cones in a position suitable for
driving the bobbins at the velocity required by the next layer of slubbing or
roving.
We wish it to be understood that we do not confine ourselves to the special
forms in which this is set forth as different portions of the apparatus may be
varied.
The whole apparatus may be placed in a horizontal position instead of
vertical; the oscillating plate may have only one incline and stop, and the
cone be furnished with two pins. The cone shaft may make an entire
rotation, and effect its changes by proportional wheels; the cams used may

page_text: be adapted in configuration to suit different methods of employing them. It
is also obvious that the instruments above described may be adapted to the
copping motion of winding frames and throstles, these being machines of the
same class.
And in order that our Invention may be more fully understood and readily
carried into effect we will proceed, aided by the accompanying Drawings,
more fully to describe the same.
Our improvements relate to that portion of the slubbing and roving frame
by which the lift is regulated and the copping motion is governed. In the
description which follows, and also in the illustrative Drawing, we exhibit
our improvements as adapted to the roving frame, and we observe that the
same letters and numbers of reference aro used to indicate the same or
corresponding parts in all the Figures in which they occur.
On each Figure
will be found the scale to which it is drawn.
Figure 1 is a back elevation of part of a roving frame, and shows tho
greater portion of our improvements and their connection with the well-known
parts of the frame; Figure 2 exhibits the shafts which are actuated by the
descent of a weight raised by the operative when adjusting the frame for a
new set of bobbins and the various connections of the said shafts; Figure 3 is
a section of the friction box and its details by which the changes of the frame
are chiefly effected; Figure 4 exhibits a plan and elevation of the lever with
inclines, by the oscillation of which the friction catch box is engaged and
released; Figure 5 exbibits a plan and elevation of the bracket by which the
top of the cam shaft and the above-mentioned plate with inclines are carried;
Figure 6 exhibits a plan and elevation of the cam and oscillating L lever by
which the lift motion is reversed; Figure 7 exhibits a plan and elevation of
the cam or cams for releasing the catches.
On one of the spring pieces A is fastened the bracket B in which the
shaft b rotates. On the shaft 6 is fastened the cone b¹, which does not enter
into our improvements except as the strap is moved thereon, as herein-after
described. The bevil pinion c is also fastened on the shaft b, and it is geared
with the pinion c', which is fastened upon the upright shaft a, which is
supported at its upper end by the bracket c fastened on the spring piece A ;
its lower end is formed into a pivot which enters and is carried by the upper
end of the shaft a' in linear continuation with it, as seen in Figs. 1 and 3, the
continuation in line being best seen in Figure 1, while the mode in which the
pivot on the end of the shaft a enters the step in the upper end of the shaft a¹
is best seen in Figure 8, which exhibits a section of this part of our
improvements. The shaft a' is supported at its upper end by means of the

page_text: fixing D, which is fixed upon the large bracket E fixed upon the spring
piece A, as seen in Figure 1. The said shaft a' is supported at its lower end
by the bracket F, also fixed to the spring piece A. Upon the shaft a' there
are fastened three cams a, a, and aº. The cam a' is formed and adjusted so
as once in a revolution to release and engage the adjustable catch lever e".
The cam as is similarly formed to a', and is adjusted to release and engage
the catch lever el alternately with e". The catches e, e, are held in gear
by the spring el. The cam a is properly an eccentric, and is adjusted within
the longitudinal slot in one arm of the L lever a so as to put it to and fro
once in a rotation of the shaft a'. This reciprocation is imparted to the
rod a' by the other arm of the L lever. The fork aº is fastened upon the
rod a', and fits easily the ring groove in the boss of the bevils g, g', which
move as one wheel by means of their connecting boss 93. The reciprocation
of the rod as is thus imparted to them, and they are put alternately in gear
with the pinion g' on the shaft g once in every rotation of the shaft a'. The
bevil wheels 9 and 9, as is well known, govern the rise and fall of the
bobbins, and are connected with the differential motion wheel and with the
lower cone, but these well-known connections which we do not alter or
otherwise connect with our improvements we do not further describe. The
fixing frises and falls with the bobbin rail, and carries the shortening box f
with it, being bolted thereto. Into the long slot in the shortening box f there
works the stud få on the end of the rack f³. The rack f³, as shewn in
Figure 2, passes through a socket in the plate f, which by this communication
with the bobbin rail through the rack has an oscillating motion; it has for its
centre of oscillation the shaft e; this oscillating plate f bas two adjustable
screws f, f, passing through ears cast upon it near its upper edge, one
on each side of it; these screws f³ and fe are furnished with lock nuts by
At each oscillation
which when properly set they are permanently fastened.
one or other of the screws comes into contact with the projecting tongue f'
on the plate with inclines d', seen detached at Figure 4. The time of this
oscillation is, as is well known, related to the position of the stud f' in the
shortening box f, which position is continually altered as the bobbin is being
filled. The ratchet e fastened upon the shaft e" is alternately held and

released by the catches e" and e¹, as herein-before described.
shaft e is also fastened the bevil e, which is geared with the bevil e fastened
on the upright shaft e*. To this shaft is also fastened the barrel e' on which
the chain e¹ is lapped, and which chain is connected at its other end to the
weight e; this weight e being suspended by the chain e' over the fulcrum
ulley is continually tending when the chain has been wound on the barrel

page_text: to unwind it therefrom, and in so doing to cause the shaft e', and by the
bevils and also the shaft e", to turn round, and it is also heavy enough
when so tending so soon as the catch which is in gear is disengaged actually
to move the shafts round until stopped by the other catch. Upon the shaft e
is fastened the pinion e, which gears with the rack f³ and gradually alters
the position of the stud f in the slot of the shortening box f, and determines
the completion of one oscillation of the plate f* by a different length of lift of
the bobbin rail, and as the descent of the weight tends to shorten the length
of rack projecting through the socket of the plate fa shorter lift of tho
bobbin rail successively effects this oscillation as the bobbin is being filled.
On commencing a new set of bobbins the operative raises the weight e, and
adjusts by the same operation the position of the rack as well as the stud f
in the shortening box; this is effected through the pulley e¹. The descent
of this weight by means of the shaft e', above described, also changes the
position of the cone strap. On the shaft e' is fastened the pinion e³ geared
with the rack e, which is the well-known continuation of the cone strap fork,
and does not need further description. The projecting tail f' of the plato
with inclines d communicates the oscillation it receives from the screws f³, f³,
to the plate with which it is cast. The plate d oscillates on the stud
fastened in the fixing D; it is kept from vibrating by means of the stud and
spring d. The inclines upon it are so placed as to divide the rotation of the
shaft a into two equal parts; this is effected as follows, namely, on the
shaft a is fastened the cone d', being one-half of a friction clutch box.
Through a hole in this cone passes the releasing stud d³, which is rather
longer than the thickness of tho cone through which it passes; when
released from the inclines upon the plate it projects underneath, when
resting upon either incline it projects above the cone; it is connected at its
upper end with the circular plate d', which is kept in a true horizontal
position by means of one or more studs d' rivetted in it and passing through
holes in the conc d'. This plate d³ is brought into contact with the surfaco
plate d², which is free to move longitudinally on the shaft a, but rotates with
it by means of pins or keys fastened in its boss entering corresponding grooves
in the shaft a. The outside of the boss of the surface plate d is screwed
with a very fine thread; the inside of the boss of the cone d is also corro-
spondingly screwed, and is let on the boss of the surface plate so far as when
the stud is released from the inclines, and it is permitted to fall or is
pressed by the spring a' it will come into frictional contact with the cone d
before described. The cone d is carried round by a key or keys driven into
a groove or a series of grooves, one of which is cut in the external surface

page_text: of the boss of the surface plate d², and the other in corresponding grooves
cut in the internal surface of the boss of the cone d. These grooves may
be varied in number according to the accuracy of the adjustment required
by the angle at which the frictional surfaces in contact are cut, so that the
smallest required amount of friction may be imparted to the cones necessary
to communicate motion to the cams by which the various changes above
described are effected. Thus suppose four such equidistant grooves are cut
the cone may be pressed firmer by one-fourth of a turn of the screw or
released by so much, and so of every other number of corresponding grooves.
It is also obvious that if four grooves are made in one of the bosses, and one
in the other, the same proportional advantage will be gained.
We have thus set forth our improvements as adapted to a roving frame,
and from the Drawings and description any mechanic conversant with the
subject may easily adapt them to the slubbing frame or to winding machines,
throstles, and machines of the same class. We have shewn our improvements
adapted to an upright shaft, but it will be obvious that they may be placed
without difficulty by a competent person in a horizontal position. We have
shewn the plate do with two inclines, and the cone d' with one disengaging
pin d'; it is obvious that the plate de may be made with one incline, and the
cone d' with two disengaging pins d³. The cone d' and the shaft a' on which
it is fastened may make one revolution at each change, and the difference be
imparted to the cams by wheels of different size, according to the configuration
of the cams employed; the cams also may be varied in their forms and modes
of action, and the parts on which they operate may be variously altered; but
all these alterations we regard as modifications of our improvements.
Having now described the nature of our improvements, and the manner in
which the same are to be carried into effect, we desire to say that while wo
do not claim those portions described and shown which are well known and
in common use, as, for instance, the weight e and the various operatious which
are effected by it during and by its descent; but we claim,-
Firstly, the application and use of a friction clutch box brought into
operation by the removal of one incline on a plate from contact with a
disengaging pin, and so adjusted that a second incline thereon shall at a
proper time again disengage the said clutch box or any equivalent means, as
by two pins in the cone and one oscillating incline, or one complete rotation
of the cone at each release, and the employment of wheels having teeth
proportioned to the changes required.
Secondly, the adjustment screw and key or keys and the grooves above
described by which the said cones are tightened or released.

page_text: Thirdly, the two cams by which the adjustable catches which control the
lescent of the weight e are engaged and released.
In witness whereof, I, the said Edmund Hartley, for and on behalf of
myself and the said Samuel Radcliffe Platt, have hereunto set my
hand and seal, this Eighteenth day of February, in the year of our
Lord One thousand eight hundred and sixty-seven.
