fiiyuill whom it may concern:
' Bie it known that I, PETER E. )IcCuL- UJKUGH, a citizen of the United States, and ir esiicllent of ll'o 'iedale, count of 'm'cester,
Smite of Massachusetts, have invented an lmzpxroveinent in Bobbin-Driving .\leans for fi mzatable Spindles, of which the following iillescariptioii, in connection with the accompaniyling drawing, is a specification, like letters on tilhe drawing representing like parts.
"lilhis invention has for its object the prodluetiiion of novel and ciiicient means for retziiniiing a yarn receiver or bobbin in position upmn a rotatable spinning, twisting or simi- Lar .sjpindleand driving the bobbin in unison Witlh the spindle.
rings encircling the head of the bobbin, to be Ilil w invention is particularly ada Med for use iin connection with bobbins e'mp oved in fililll3eililltlil(' iilling-replenishing looms, such bmblbins having aseries of metallic. spring engaged by holding means in the shuttle Wham the bobbin is inserted automatically theaiein. I
I lhave so constructed and arranged the bmblbin driving means. in my present inventll wlm that the rings themselves are friction :and tangentiallv engaged, to eiiect the rotation of the bobbin, thereby obviating changes in the wood'of the bobbin due to un- EKdttllillll wear, variations in temperature, moisturex, etc.
t v'engaging the rings the frictional con- V tact is increased, and inasmuch as the outer circ mnfcrence of the rings is engaged the tem'liency is to center them with relation to the spindle, thereby overcoming the action oti centrifugal force, which would otherwise malhe the spindle run untrue it the rings werie materially non-centered, as sometimes hapqpens.
in accordance with my invention the spindille lhas mounted upon it a laterally expansible (cup-like niemberinto which the head of the lbobbin enters, the said memberfriction- :iilll :and tangentially engaging the periph elders of the rings on the bobbin-head and thereby effecting a. driving connection betwee-n the bobbin and spindle.-
Tlhe bobbin is readily and easily applied to the spindle and the friction driving member, and as easily withdrawn.
'lilhe various'novel features of my invention will be fully described in the subjoined specifica'tion and particularly pointed out in the following claims.
Figure 1- is a side elevation of a rotatable spindle with driving means applied thereto embodyingone form -of my presentinvention, a bobbin being shown in operative position, the bobbin and spindle being broken out tosavespace; Fig. 2 is a vertical diametral section of the apparatus shown in Fig. 1 Fig. 3 is a top plan view of the spindle and bobbin driving means.
In the present embodiment of my invention the spindle 1, of usual construction, and reduced at its upper end at Fig. 1, to enter the reduced bore at the tip of the bobbin, has
iixedlv attached to it a depending sleeve 3 provided at its lower end with a whirl 4, the upper end of the sleeve having a central hub 5 embracing the spindle, Fig. 2.
Upon the sleeve and surrounding the hub 5 I fixedly secure a circular bobbin-rest 6, re-
cessed to fit the upper end of the whirl sleeve,
as shown in Fig. 2, the bobbin-rest forming the bottom of a relatively deep cut, the circular wall of which is formed by a series of thin res lient or spring fingers 7, transversely segmental, as shown in Fig. 3, and concentric with the spindle, the inner faces of said fingers being straight longitudinally.
In practice the bottom and side wall of the cup are integral, the fingers being formed by longitudinally slitting the wal'i,.as at 8, to make the cup laterally yielding or expane sible, the inner diameter of the expansible wall being normally slightly less; than the external diameter of the rings 9 on the head 10 of the bobbin.
When a bobbin is applied to the spindle the. head 10 is pushed into the cup and against the rest 6, thereby insuring a fixed verti ail position of the bobbin relatively to the spindle, and the inner faces of the resilient, fingers 7- frictionally engage the rings 5), as shown in Fig. 2', the cup being expanded slightly as the rings move over its inner surface during the seating of the bobbin.
A light vet firm and eil'ective frictional en-. gagement is thereby secured, constituting a frictionv drive or connection between thespindle-and bobbin'and insuring the rotation of the latter in unison with the spindle.
The inherent spring of the rings, coopersyn-n ating with the resiliency of the fingers form-v ing the wall of the enp," assist in: securing a, good'friet-ional engagen'ient and driving conneetion. The cup wall is in tangential engagement with the outside of the rings, and tends to center the rings with relation to the spindle obj'iating any tendency to make the spindle run untrue, even if the rings are considerably off center. It will be seen by referenceto Fig, 2 that as thedrivmg contact is wholly external, and on the rings, any variations or irregularities in the. head or bore of the bobbin are of no moment.
V The head of the bobbin is held in the cupand a series of upturned, segmental and straight resilient fingers rotating with and surrounding the splndle, said fingers receivlng between them the bobbin head and driving the same by frictional and tangential.
engagement with the peripheries of the rings.
.2; A rotatable spindle having an attachedwhirl and a, circular bobbin rest above the V whirl, combined with a. bobbin having a seriesof rings on its head,and a resilient, exansible annular wallrismg from the bob- )in rest, to receive the bobbin head and thereon, to-efiecta driving connection be- V frictionally and tangentially engage the rings tween the bobbin and spindle, the end of the bobbin head engaging the bobbin rest. 3. The combination, with a rotatable spin- 'dle of a deep,longitudinally slotted cup rotatable therewith and having a thin, straight and-resilient wall, to frietionally and tangentially engage the rings on a bobbin head when inserted in the cup and thereby effect a. driving connection between the bobbin and spindle.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
