being delivered into a basket element shown at as pro
ing screw of this assembly is indicated at 100‘ and forms
vided with an exit screen to catch the yarn ends but
permit free flow of air.
The ring 23 which forms part of the dial cap is pro
vided with three notches which may be best de?ned by
their cutting edges 42, 44 and 46 at their counterclock
wise sides. These edges provide a shearing action by
cooperation with the ?ns 28. As will be evident par
ticularly from FIGURES 2 and 3 the peripheral edge 47
of the ring 23 extends slightly outwardly beyond the
ends of the ?ns 28 except at the notches. in order to
provide proper handling of the yarns, various clamping
and guiding elements are provided. A guard 48 taking
the form of a thin sheet of spring metal has an upturned
end 50 (see FIGURE 5) and a downwardly extending
lip portion 52 which extends radially beyond the periph
ery 47 of ring 23 above the locations of the notch pro
viding the cutting edge 42.
The guard 45; is secured
to the top of the dial cap by a screw 54 and normally
has slight clearance with the upper surface of the dial
cap. Located above the guard 43 is a clamp member 56
of thin spring metal which is also secured by the screw
54 to the dial cap. The clamp member 56 has an up
turned end 58 which, as shown in FIGURE 5, is spaced
above the end 50 of the guard 48. The clamp member
56 when relieved of pressure springs upwardly slightly
away from the guard 48 to provide a space for the free
movement of yarns. A second guard member is pro
vided at 60 and has an upwardly direct free end 62 as
shown in FIGURES 4 and 5. It also is provided with a
a pivot for the mounting of an auxiliary clamp member
102 similar to 84 and provided with a vertical elongated
slot 104 loosely embracing the shank of the screw 100.
This auxiliary clamp member 102 is provided with a bev
elled entrance portion 106 to facilitate the entry of
yarns. Like the clamp member 84 it bears, of its own
weight, against the upper surface of the dial cap, and
does so at a position counterclockwise beyond the clamp
member 56 and guard 48. The lever 96 is provided with
a laterally extending ear engaged by the upper end of
a tension spring 108, the lower end of which is anchored
to the dial cap. The lever ‘96 carries a follower element
110 pivoted to it at 112 and arranged to be clamped
in adjusted position by a screw 114 threaded to lever
96 and passing through a slot 116 permitting adjustment.
The follower 110 overlies the lefthand portion of lever
76 and when the lever is rocked by downward move
ment of the link 80 the lever ‘96 is lifted against the action
of spring 108. Spring 108 is a strong one and through
the connections described exerts suf?cient pull to effect
downward clamping of the clamp members 56 and 70
and their associated guards.
A pin 113 extends upwardly from the top of the dial
cap and serves for yarn guidance ‘as described hereafter.
The operations involved in the making of yarn changes,

an upturned end 72, being secured to the dial cap by a
screw 74. The normal condition of the clamp member 72 60
