Improvements in Apparatus for Winding Card Filleting upon
Cylinders.
I JOSEPH STANDRING DRONSFIELD of the Firm of Dronsfield Brothers
Limited, of the Atlas Works, Oldham, in the County of Lancaster, Card
Grinding Machine Makers, do hereby declare the nature of this invention to be
as follows:-
My said invention relates generally to apparatus employed in the covering of
cylinders with card fillets as is now well understood by those acquainted with the
carding industries. I will however for the sake of clearness refer more particularly
to its application in conjunction with apparatus of this nature for which Her
Majesty's Letters Patent-have been granted to me under Number 7290 of 1891.
It is essential in such apparatus that measurable and uniform tension should be put
upon the filleting as it is coiled upon the cylinder and with this object a spring
tension regulator and indicator was described and ascertained in the Specification
annexed to the said former Patent. The present invention. relates to means
whereby such spring tension regulators and indicators are made more delicate and
uniform in their operation, and so as to respond at once to any retarding influence
brought to bear upon the fillet in its progress over or through the head, of whatever
construction the latter.may be...
:
In carrying my invention into effect I make use of an arm pivotted at the..
delivery end of the head and presenting a smooth guiding surface preferably..:
of a trough section, over or through which the fillet is led. when it leaves. the head.
The head may consist of a stepped cone in conjunction with an. arrangement: of.
curved shunting surfaces as described in my said.former Patent.or.it may consist
of any other: suitable or known arrangement: for giving the requisite frictionals:
resistance and extension to the filleting. The aforesaid pivotted arm is of a bell..
crank form, one member of the arm standing vertically and serving as a guiding
or carrying surface for the filleting while the other member extends horizontally
and is attached through the medium of a spring or a set of springs to a fixed-part
of the head. The filleting as it leaves the head is drawn over or through, the
vertical guiding:surface of the pivotted arm and thence to the cylinder upon which
it is to be coiled.. That member of the arm which constitutes the guiding surface:.
is of sufficient length to form a lever readily responsive to the pull of the filleting-
and thus secure a delicate measure of tension, the arm. vibrating upon its pivot
in response to the smallest increase or decrease of tension. The. pull of the
filleting upon the arm is resisted by the springs. which are connected to the end
of the other or horizontal.member. of the arm, so that the requisite elastic and
resilient give-and-take. action is obtained. Either. member of the rocking arm
may be connected' in any suitable manner to an indicatore with figured index
showing the exact tension to which, the filleting is being subjected. A suitable
mode would be to pivot an index finger to the end of the head, a fork extending
from the side of the finger and engaging with a stud projecting from the horizontal
member of the arm. The top edge of the head end.to which the:finger is pivotted, -
may be prepared as a figured index, over which the point of the index finger moves
so as to indicate the exact tension upon the filletings have found in practice
that in a head: provided with my..present improved spring tension indicator and
=

page_text: with the improved presser trough with adjusting screw as described in the aforesaid
Specification, the usual brake pulley and strap on, the axis of the stepped cone
may in some cases be dispensed with.
So long as a pivotted arm or lever is used to lead or deliver the filleting from the
head to the cylinder, the shape or mode, of applying such lever might be varied.
Weights also might be used instead of springs, and as already said the described
improved spring tension regulator and indicator might be used in conjunction with
any existing or suitable apparatus for coiling filleting upon cylinders.

Improvements in Apparatus for Winding Carḍ Filleting upon
Cylinders.
I JOSEPH STANDRING DRONSFIELD of the Firm of Dronsfield, Brothers. 15
Limited, of the Atlas Works, Oldham, in the County of Lancaster, Card
Grinding Machine Makers, do hereby declare the nature of this 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.

My said invention relates generally to apparatus employed in the covering of 20
cylinders with card fillets as is now well understood: by those acquainted with the..
carding. industries. I will however for the sake of clearness refer more particularly..
to its application in conjunction, with apparatus..of this nature for which Her:
Majesty's Letters Patent have been granted to me under Number 7290 of 1891...
It is essential in such apparatus that measurable and uniform. tension should be put 2
upon the filleting as it is coiled upon the. cylinder and with this object a spring...
tension regulator and indicator. was described and ascertained in the Specification.
annexed to the said former Patent.
The present invention relates to means whereby such spring tension regulators.
and indicators are made more delicate and uniform in their operation and so as to 3
respond at once to any retarding influence brought to bear upon. the fillet in its.
progress over or through the head of whatever construction the fatter may be. .
The annexed two sheets of drawings illustrate my present invention.

Fig. 1 is an end view of a card fillet winding.head similar in designs to the head 3
which appears in the drawings of the. aforesaid former Patent but furnished in
this instance with the spring tension. lever which forms the. gist of my present:
invention.

sole A (see Fig. 3) and the spindles B₁ of the stepped pulley; B is carried ins
bearings in the ends of the bead A. The revolution of the stepped pulley Bris
retarded by the brake-strap and pulley.b as in the case of my said, former
apparatus: The shunting bracket is bolted. to the ends A: by means.
of thes
flanges C¹ C¹ and also carries a presser guide 2 through which the filleting passes,c50
to the stepped pulley BAll of these partscarezoldi andɔhave already „been..

page_text: described; in my said former: Patent. At the delivery end of the head I provide
a double bracket e and: within this bracket and upon the stud f I pivot myi
improved new tension. lever D. which is shown separately in Fig. 4 of the
drawings.
1. !
The tension lever is of a bell crank form, one: limb D'projecting upwards and
being formed with a curved surface adapted to receive the filleting as it leaves the
stepped pulley, while the horizontal limb D' extends to the back of the head, the.
outer end being connected by three or any other suitable number of springs g g g
to fixed studs h h h in the upper part of the head the said springs engaging with
studs hhh projecting from the tension lever all as appearing most clearly.in
Fig.1 of the drawings. The curved guiding surface of the limb D is smoothed.
and finished, and, extends from about the pivot stud f to the upper extremity of the
limb.. The guiding surface is fenced on both sides by beads to keep the filleting
in position. The filleting which is represented by the dotted line marked *in
Fig. 1 leaves the stepped pulley B: in the indicated. direction and slipping over the
curved guiding surface of the tension lever D is finally conducted to the cylinder
upon which it is being wound. In order to prevent the varying angles at which
the filleting leaves the lever from differentially affecting the tension lever, I form.
the said lever with the,extended curved part at the top as shown, this surface:being
struck from the centre of the pivot f. By this means. I. ensure that even when the
angle at which the filleting, leaves the lever is altered (by variations in the size
of the cylinder or from other causes) from the angle to the angle ** for example,..
the radial length of lever remains the same and the pull on the lever is unaltered.
The horizontal arm-Dof the lever is furnished with a too-k (see Fig. 4) which
encounters a stop projecting. from the inner side of the end-A. This toerand stops.
prevent the lever D from being pulled by the springs 9 9.9 past.a normal position
when the lever D is free from the filleting. It will now be understood that as the
filleting passes over the lever D the lever yields in the direction of traverse, the
limb D pulling on and extending the springs 999. I will now describe how-
the movements of the lever are communicated to an indicator by which the operator
can tell exactly what tension is being put upon the filleting. From the limb D¹ of
the lever there projects a stud which passes through a slot in the end A, this slot
appearing in Fig. 1. In the outer side of the end A I fix a pivot stud m the said
stud carrying a slotted counter-balance n shown separately at Fig. and also an
index finger o shown separately at Fig. 6. The index finger and counterbalance
are fixed together by a pin or other means when placed upon the stud as in Fig. 7"
and are boxed in by a cover plate p secured by screws to projections from the end,.
a portion of this cover plate being shown broken away in Fig. 1 to show the parts
behind more clearly. The curved upper edge of the end A is struck from the
centre of the stud m and is finished and bears a figured scale showing the tension.
in pounds. The tip of the index finger o plays over this scale in obedience to the
movements of the limb D' of the tension lever and shows at a glance what tension
the filleting is subjected to.
2"
When at work the head is traversed upon shears by a screw engaging with the-
worm wheel which is fixed on a spindle s supported in bearings t carried by the
head A. At such times the worm wheel r acts as a nut, and to bind the spindle s
immovably in its place and so keep the worm wheel r from turning, I provide a
binding eye bracket u connected at v to the head, while its split eye embraces an.
enlarged portion & of the spindle s. The split eye is drawn together so as to bind
the spindles therein by means of a screw w with wing nut wo. When it is desired.
to traverse the head quickly over the shears, the nut w' is relaxed, and a handle is-
put on the squared end 2 of the spindles which can then be turned and as the
worm wheel gears with the traversing screw as with a rack, the lever is quickly
moved towards either end of the shears. The only part of the arrangement which
is novel is the enlarged portion of the spindle s in combination with the split eye u
with its jambing bolt, the extended jambing surface enabling a better grip to be
taken of the shaft s..

page_text: The tension.lever D which I have described and illustrated might be used not
only in conjunction with the specific form of fillet winding head which I have
particularised but also with other apparatus for coiling card filleting upon cylinders.
It will be evident that instead of the springs 9 9 9 as described weights might be
used to give.the requisite tension to the lever D.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what. I
claim is.
1. In combination with apparatus for coiling or winding card filleting upon
cylinders, the tension lever D pivotted at the delivery. end of the apparatus and
sustained by springs or weights against the pull of the filleting, the said lever being
connected to indicating means such as the index finger o working over a figured
scale whereby the amount of strain put upon the filleting.can be ascertained at a
glance substantially as described and as illustrated:
2. In combination: with apparatus of the indicated nature the tension lever D
having a curved upper part struck from the centre of the pivot which carries the
lever, for the purposes and substantially as described and shown.
3.. In, combination with card. fillet winding, apparatus of the indicated nature,
the tension lever D, the springs ggg connecting the lever to a fixed part of the
head, the stud 1, the counterbalance fork n and. the index finger o substantially as
described and shown..
4. As. an adjunct to the described apparatus the combination of the enlarged
portion of the spindle s with the split eye or boss u and jambing bolt and nut w w
for the purpose and substantially as described and shown...
