IMPROVEMENTS IN WOOL COMBING AND PREPARING MACHINERY
Year: 1884

page_text: EDWIN GREAVES HATTERSLEY of Mytholmes Mill, Haworth in the County of
York; and Burrage House Harrogate in the same County, Manufacturer, and
SPENCER HIRD of Mytholmes Mill, Haworth, Manager, do hereby declare the
nature of our invention for IMPROVEMENTS IN WOOL COMBING AND PREPARING
MACHINERY to be as follows:-
The said invention is a new or improved application of parts to all wool
combing and preparing machines in which yielding draw rollers are used whereby
the motion of the machine is stopped when, by accident or otherwise, the wool
begins to wrap the said draw rollers or after having passed through these rollers it
fails to follow the usual guide pieces into its proper receptacle.
The principle of our invention being the same whether applied to combing or
preparing machines we will describe it in connection with the former and it will be
easily understood how the same may be applied to the latter, such as-first
preparer, gill box, balling box, etc.
In that class of machine commonly known by the name of Lister's combing
machine, to which our invention has more especial reference, the upper drawing-off
roller is pressed into contact with the bottom drawing-off roller (through which it
derives its revolving motion) by means of an adjustable spring arrangement which
allows the necessary yield, to the said upper drawing-off roller, to suit the various
thicknesses of wool that have to pass between the said rollers.
To that part of the frame-work of the machine, which serves as guide for the
yielding or upper drawing roller and support for the adjustable spring, we mount
two levers on suitable bearings, one at each end of the said yielding roller. One
arm of each of these levers is made to come in contact with projections formed on
the moveable bushes which convey the spring pressure to the arbour of the yielding
roller at each of its ends respectively.
The other arms of these levers are separately (on one side directly and on the
other by the intervention of suitable parts) connected loosely to two of the three
arms of another lever which is also mounted in bearings fixed to an appropriate
part of the said frame work. The other arm of this last mentioned lever extends
outwardly sufficiently far to come in contact with the bent or inclined end of a
suitably shaped spring, when the said spring is held in a state of tension by a
notched or recessed stand or guide which, together with the spring, is fixed to the
frame work.

;
From this description it will be easily conceived that at each yielding movement
of the before mentioned yielding roller, caused by an extra amount of wool
passing between the said rollers, as when the wool begins to wrap; an upward
movement will be given, through the medium of the lever connections, to the outer
arm of the three armed lever, thus bringing it in contact with the bent or inclined
end of the spring, before mentioned as being held in a state of tension, which, by
the pressure of the said lever arm, pushed beyond the notch or recess in the
stand or guide and so set free to move to its reposing state. This spring when
thus moving, by coming in contact with parts fixed to the slidable belt guide har,
pushes the driving belt from the fast to the loose pulley of the machine and so
stops its motion.
The latter. part of our invention, viz.-the stopping of the machine when the
wool fails to follow the usual guide pieces into its proper receptacle is accomplished
by the use of a suitably proportioned lever mounted in bearings on the framework.
One arm of this lever is made, by the application of a spring or weight, to press
against the wool immediately before it enters the guide rollers which deposit it in
its proper place, but should the wool be absent or held loosely at this part, the arm
of the lever, which it (the wool) should hold down, is liberated and the spring or
weight causes it to rise and bring with it an adjustable finger which is rigidly
attached to it. This finger projecting underneath the outward arm of the three
armed lever, mentioned in the former part of our description, imparts to it the
required upward movement to act upon the bent or inclined end of the spring in
the manner and for the purpose previously described.
The foregoing is a description of only one arrangement of parts whereby the
desired effect is produced, but other appliances, may be used such as a simple lever
of the "first order," one of its arms being in contact with both ends of the yielding
roller and the other striking the bent topped spring direct without the intervention
of the supplementary levers and parts. Also the lever which presses against the
wool may be made, when liberated, to stop the machine direct; in this case the
two motions would act independently of each other, but for compactness and
mechanical neatness we prefer to use the parts as fully described.
Again, as it is found in practice that the end of the yielding roller (in combing
machines) nearest the belt guide bar is almost invariably the one that is lifted,
when the wool wraps, we might apply our invention to that end alone; but, of
course, in this case the result would not be so effective.
Since the top draw roller in preparing machinery is made to yield in the same
manner as that described in connection with the wool combing machine, and the
guide pieces for the wool in both machines are very similar, it will be easily
understood that similar results may be obtained by a slight alteration in size and
shape of the various levers and bearings, used as previously described, in order that
the same might fit the different forms of framework in the different machines.
Dated this 14th day of March 1884.

page_text: We, EDWIN GREAVES HATTERSLEY, Mytholmes Mill, Haworth, and Burrage
House, Harrogate, Manufacturer, and SPENCER HIRD, Mytholmes Mill, Haworth,
Manager, all in Yorkshire; do hereby declare the nature of our invention for
IMPROVEMENTS IN WOOL COMBING AND PREPARING MACHINERY and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:―
:
The said invention is a new or improved application of parts to all wool combing
and preparing machines in which yielding draw rollers are used, whereby the
motion of the machine is automatically stopped when, by accident or otherwise, the
wool begins to wrap the said draw rollers, or after having passed through these
rollers it fails to follow the usual guide pieces into its proper receptacle.
The principle of our invention being the same whether applied to combing or
preparing machines we will describe it in connection with the former and it will be
easily understood how the same may be applied to the latter, such as first preparer,
gill box, balling box &c.
In order that our invention and the manner of performing the same may be
properly understood we have hereunto appended a sheet of explanatory drawings
wherein Fig. 1 is an end elevation, Fig. 2 a front elevation and Fig. 3 plan of a
suitable portion of that class of machine commonly known by the name of Lister's
Combing Machine; while Figs. 4 and 5 are detail drawings of same. Like letters
and figures indicate like parts in all the drawings.
In this class of combing machinery the upper drawing-off roller a is pressed into
contact with the bottom drawing-off roller b (through which it derives its revolving
motion) by means of an adjustable spring c which allows the necessary yield, to the
said roller a, to suit the various thicknesses of wool d that have to pass, between
the said rollers a and b.
To that part A¹ of the frame work A which serves as guide for the roller a and
support for the spring c, we mount two levers e and e¹ on bearings f and fl one at
each end of the roller a.
One arm of each of these levers e and e¹ is made to come in contact with
projections or flanges g formed on the moveable bushes h which convey the spring
pressure to the arbour of the roller a at each of its ends respectively. The other
arms of the levers e and e¹ are separately (the lever e directly and the lever e¹ by
the intervention of the bell cranked lever i and connecting rod j) connected loosely
to two of the three arms of the lever k which is mounted in bearings fixed to the
frame-work A. The other arm of the lever k extends outwardly sufficiently far to
come in contact with the bent or inclined end m of a suitably shaped spring B
when the said spring B is held in a state of tension by a notched or recessed stand
or guide C which together with the spring is fixed to the frame-work A..
From this description it will be easily conceived that at each yielding movement
of the beforementioned roller a caused by an extra amount of wool d passing
between the said rollers, as when the wool begins to wrap, an upward movement
will be given, through the medium of the levers e, e¹ and i and the connecting
rod j, to the outer arm of the three armed lever k; thus bringing it in contact with
the bent or inclined end m of the spring B, when the said spring is held in a state
of tension as shewn in dotted lines Fig. 1, pushing the said spring B beyond the
notch or recess in the stand. C and so setting it free to move to its reposing state.
This spring B when thus moving by coming in contact with part n fixed to the
slidable belt guide bar D pushes the driving belt E from the fast pulley F to the
loose pulley G of the machine and so stops its motion.

page_text: The spring B may be substituted by using a lever fulcrumed on the framework A
as shewn in detail drawing Fig. 4 B¹, the said lever B¹ being drawn in the desired
direction by a spring H also fixed to the framework A and the lever B¹.
The latter part of our invention, viz:-the stopping of the machine when the
wool d fails to follow the usual guide pieces o, p and p¹ into its proper receptacle J,
is accomplished by the use of a suitably proportioned lever r mounted in bearings s
on the framework A. One arm of the lever r is made, by the application of the
spring t, to press against the wool d immediately after it leaves the guide o and
before it enters the guide rollers p and p¹ which convey it into the receptacle J,
but should the wool be absent or held loosely at this part, the arm of the lever r
which it (the wool) should hold down, is liberated and the spring t causes it to rise
and bring with it an adjustable finger ¹ which is rigidly attached tɔ it.
This finger projecting underneath the outward arm of the lever k mentioned
in the former part of our description, imparts to it the required upward movement
to act upon the bent or inclined end m of the spring B in the manner and for the
purpose previously described.
The foregoing is a description of only one arrangement of parts whereby the
desired effect is produced, but other appliances may be used such as a simple lever
of the "first order," shewn in detail drawing Fig. 5 k³, one of its arms being in
contact with both ends of the yielding roller a and the other striking the bent
end m (which is reversed in this case to suit the movement of the said lever k³) of
the spring B direct without the intervention of the supplementary levers e, e¹ and i
and part j. Also the lever when it is liberated may be made (either by
extending its outer arm; or by-arranging its adjustable finger r¹, to act upon
the bent end m of the spring B in the manner as before described) to stop the
motion of the machine direct; in this case the two motions would act independently
of each other, but for compactness and mechanical neatness we prefer to use the
parts as fully described.
Again as it is found in practice that the end of the yielding roller a (in Combing
Machines) nearest the belt guide bar 1) is almost invariably the one that is lifted,
when the wool wraps, we might apply our invention to that end alone; but, of
course, in this case the result would not be so effected.
Since the top draw roller in preparing nachinery is made to yield in the same
manner as the roller a described in connection with the wool combing machine, and
the guide pieces o, p and p¹ in both machines are very similar, it will be easily
understood that similar results may be obtained by a slight alteration in size and
shape of the various levers and bearings used as previously described, in order that
the same might fit the different forms of framework in the different machines.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed we declare that what
we claim is :-
1. The means or method of utilizing the motion of the yielding rollers in
combing and preparing machinery in the manner and for the purpose as fully
described and set forth.
2. The use and application of the lever r both separately and in connection with
the lever k substantially in the manner and for the purpose described.
