COMPLETE SPECIFICATION.
An Improved Clutch for Use with Spinning Frames, and for other
purposes.
I, JOHN EBENEZER BOUSFIELD, of the Firm of G. F. Redfern & Co., The
General Patent Office, No. 4, South Street, Finsbury, in the County of London,
Patent Agents, do hereby declare the nature of this invention (a communication
to me by La Société Anonyme de Filatures de Schappe, of 5, Quai de Retz,
Lyons, (Rhône), in the Republic of France) and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
.
This invention relates to an improved clutch for use with spinning frames and
for other purposes.
The said clutch comprises two hollow-discs or cylinders mounted on the same
axis and one of which is adapted to be actuated by the other when the latter
rotates in one direction. The first of these discs or cylinders, namely, the one
which actuates the other, carries loose on its boss a couple of arms each of which
serves to hold a pair of jaws adapted to oscillate on pivots fixed to the said hollow
disc or cylinder and limits the oscillatory movement of the said jaws, whilst the
second disc or cylinder is provided with a ring which enters notches in the above
mentioned aruns between the jaws of each pair, the arrangement of the said arms
being such that they only allow the jaws to execute. a slight movement on their
pivots, which movement causes each pair of jaws to grip the ring fixed to the
second disc or cylinder when the first disc or cylinder rotates in one direction, the
jaws not gripping the ring when the first cylinder rotates in the reverse direction.
To enable the invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which :-
.
Figure 1 is a longitudinal section of a clutch constructed according to my
invention, the jaws being represented in the position they occupy when gripping
the ring fixed to the second disc or cylinder:
F
. Figure 2 is a transverse section of the said clutch:
Figure 3 is a view similar to Figure 2 but shewing the jaws in the position they
occupy when the first disc or cylinder turns in the reverse direction to that' in
Figure 2 thereby not gripping the ring fixed to the second cylinder:
Figure 4 is a front view; and,
Figure 5 is an end view of the jaws :
Figure 6 is a front view; and,
Figure 7 is a transverse section of the two arms serving to hold the jaws :
Figure 8 is a view of a spinning frame having my improved "clutch applied
thereto.
As seen in Figures 1, 2 and my improved clutch comprises two short hollow
cylinders or discs A and F mounted loosely on a shaft or spindle a. On the boss a¹
of the cylinder A I mount a sleeve b in one piece with, or rigidly attached to, two
arms D, D each serving to hold a pair of jaws C having an arm c provided at its
free end with a notch c by means of which it can oscillate on a pivot B fixed to
the cylinder A. This oscillatory movement of the jaws C, C is limited by
grooves d, d in the arms D, D in which the arm c moves.
The disc or cylinder F is provided in its interior with a ring G which enters
notches in the arms D. D and the spaces f. f between each pair of jaws C.

page_text: The two jaws of each pair are formed, ashshewn clearly in Figure 4, of two
short parallel, surfaces i, and fof longer inclined surfaces, j, jrand k, k¹, the
arrangement of these surfaces being such that i, j, k₁ and i, j, & are arranged
symmetrically to one another around the axis, of the jaws.
E, E are springs fixed by one end to the arms D, D whilst their other ends
bear against pins 1, fixed to the cylinder A.
For the purpose of illustration
have represented the-cylinder A as actuated
by a pinion I fixed on its boss a² and I have shewn the cylinder ffixed to the
boss as of a bevel wheel J.
The operation of my improved clutch is as follows:-
If it be supposed that the cylinder A rotates in the direction of the arrow,
Figure 3, the arm of each pair of jaws C will take up the inclined position
shewn in the said figure, and the cylinder A will carry with it the jaws C, C
and the arms DD without, however, carrying the ring. G. with it, whereby
the movement of the cylinder, A, is not communicated to the cylinder F. If, on
the contrary, the, cylinder A rotates in the direction of the arrow ; Figure 2, the
arms c will take up the position shewn in the said figure whereby the edges m, m
formed by the meeting of the surfaces i, j, and of the jaws respectively will
tend to penetrate the ring G so that it is tightly gripped between the two sets
of jaws C, C and is carried with them thus causing the cylinder Eto
with the cylinder A.
'
rotate
Figure 8 shews the application of my improved clutch to anspinning frame.
In this arrangement.the, disc.or cylinder A. is mounted non aslidet Hwhich has an
up-and-down motion.communicated to it by an eccentric thereby determining
the height of the successive layers of thread wound on the bobbins. To the upper
guide of the slide H I.fix a.rack K.which engages with the pinion. I, attached.to
the cylinder A.
By the vertical-up-and-down motion of the slide H.the pinion I on the cylinder A
is caused to rotate by engaging with the rack Kwhereby the cylinder E is caused
to rotate or not according to the direction, in which the cylinder A rotates, for the
reason herein before. described, that is to say, in this case, the cylinder F. is caused
to rotate when A moves, in the direction of the arrow and does not rotate (when A
moves in the opposite.direction.
The bevel wheelt J fixed to the cylinder Eengages with the bevel wheel P
mounted on a screw: L which is supported by the slides H in such a manner that
each rotation of A in the direction of the arrow z, caused by the up-and-down
movement of the slide H, causes the screw L.to..rotate (always in the same
direction) thereby causing the nut M to descend on the screw so that at each
up-and-down movement of the slide. Hthe chains. Nfixed to the nut M will
regulate the motion of the ring carriers (chariots à anneaux) of the spinning frame
in the well-known manner.
+
The rack. K is made adjustable so that by altering its position the number of
teeth engaging with the pinion I can be varied whereby the rotation of .thes said
pinion and of the cylinder A and consequently the vertical displacement of the
nut M and the ring carriers of the spinning irame are also varied.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner, the same, is to be performed, I declare that what I
claim is :-
1. An improved clutch-for use in spinning frames and for other purposes com-
prising two hollow.discs or cylinders A and F of which A carries loose on its boss
two arms D, Dunder, the action of springs E, E and each serving to hold a pair
of jaws C, C adapted to oscillate on pivots fixed to the said disc or cylinder and
each pair of jaws; being formed with short parallel surfaces and inclined
surfaces j; j, k, k¹ arranged in such a manner that the surfaces i, j, k of one jaw
are arranged symmetrically to the surfaces i, j, k of the other around the axis of the
jaws; whilst the second cylinder F is provided with a ring G entering into grooves

page_text: or notches in the above mentioned arms and between the surfaces i, j, k and i', j', k¹
of the jaws in such a manner that according as the cylinder A rotates in one
direction or the other the edges of the jaws take up different positions and grip or
not the ring fixed to the second cylinder, thereby causing the latter to rotate or not
with the cylinder A, substantially as hereinbefore described and illustrated in the
accompanying drawing.
