\VlLLIAM E. ALLEN OF LYNN, MASSACHUSETTS, ASSIGNOR TO SAVYER SPINDLE COMPANY, A CORPORATION OF MAINE.
BOBBlN-CLUTCHING MEANS FOR ROTATABLE SPINDLES.
SPECIFICATION forming part of Letters Patent No. 769,675, dated September 6, 1904. Application filed July 5, 1904. Serial No. 215,221. \No modelfl Be it known that I, WILLIAM E. ALLEN, a 3
citizen of the United States, and a resident of Lynn, county of Essex, State of Massachusetts, have invented an Improvement in Bob- 1 bin-Olutching Means for Rotatable Spindles, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.
This invention has for its object the production of a novel form of bobbin-clutch to retain l causing them to contract when the spindle is at rest or running at low speed. By the inherent resiliency of the clutching members the bobbin is very easily applied to and removed from the spindle.
The novel features of my invention will be fully described in the subjoined specification and particularly pointed out in the following claims.
Figure l is a view, partly in section and elevation, of a portion of a rotatable spindle of the sleeve-whirl type with one embodiment of my invention applied thereto, the yarn-receiver or bobbin being shown in section. Fig. 2 is a perspective view of the clutching means detached from the spindle. Fig. 3 is a view similar to Fig. 1, but showing a different form of clutch device; and Fig. 4: is a perspective view of the clutch device detached.
1 have shown my invention as applicable to a wellknown form of sleeve-whirl spindle by a very slight change thereof, the spindle-blade 1 and its whirl 2, connected therewith by a sleeve 3 surrounding the spindle, (the whirl i being formed on the lower end of the sleeve,) beingof well-known construction. The sleeve has formed upon it an annular laterally-extended flange 4, which forms a rest for the lower end or base of the yarn-receiver or bobbin B during the spinning operation, the base of the bobbin being chambered at I), as usual.
in Figs. 1 and 2 I have shown the clutching means as composed of a piece of spring-wire formed into a series of close spiral coils 5, the ends 6 of the wire being preferably extended laterally in substantially opposite ends at the top and bottom of the coils. The free ends are slightly curved, as shown, and the coils 5 are forced down onto the spindle-blade to a position at the top of the sleeve. (See Fig. 1.) 'hen the spindle is at rest or running at low speed, the resiliency of the springarms 6 tends to contract them; but when the spindle is rotating at speed the centrifugal force overcomes the resiliency and forces the free ends of the arms outward in a lateral direction. If a bobbin is applied to the spindle, the arms 6 enter the chamber 7/. yielding as the bobbin is pushed down onto the rest L, but being thereafter forced into driving engagement with the walls of the chamber Z; by centrifugal force. The bobbin is thereby caused to rotate with the spindle, and any tendency to lift from the rest 4: is counteracted by the rcsilience of the clutching members or arms (5. The application of the bobbin to the spindle or its removal is accomplished with case, owing to the contractibility of the clutch members. The coils 5 may be made to hug the spindle-blade so tightly as to require no other fastening, or they may be secured thereto by brazing, soldering, or pinning, as desired. A conical collar 7 is preferably secured to the spindle above the clutching means to serve as a guide in placing the bobbin on the spindle, the guide acting to center til-O chambered base of the bobbin when it is slid down over the clutching means. i
In Figs. 3 and L 1 have shown another form of the clutching device, the same comprising several resilient arms 8, made of thin sheet metal, having their outer ends free and with their inner ends curved around and connected to form a collar 8, which is pushed onto the spindle and pinned in place, as at 9, Fig. 3. The members or arms 8 are symmetrically disposed with relation to the longitudinal axis of the spindle, and they present rather broad contact-faces to be moved into driving engagement with the walls of the bobbin-chamber 6 by or through the action of centrifugal force. The resiliency of the arms tends to contract the clutch device by moving their free ends inward, such tendency being over- I come by the centrifugal action.
Owing to the fact that in my present invention the clutching members are positively attached at one end to the spindle, I obviate the use of a special and separate attaching device, and the resiliency of the members does away with the use of any extraneous means to limit outward movement of their free ends when the spindle is running free or without a bobbin.
My invention is not restricted to the precise construction and arrangement shown and described, as the same may be varied or modified in different particulars without departing from the spirit and scope of my invention.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The combination with a rotatable spindle having an attached whirl and a rest for a yarn-receiver, of resilient clutching means independent of the whirl, permanently attached to and rotatable with the spindle and adapted to be laterally expanded and brought into driving engagement with a yarn-receiver by or through the action of centrifugal force.
2. The combination with a rotatable spindle, having an attached whirl and a rest for a yarn-receiver, of resilient clutching members connected with the spindle independently of the whirl, to rotate with the spindle and having their normally non-engaging free ends adapted to be moved outward in lateral paths by or through the action of centrifugal force into driving engagement with a yarn-receiver.
3. The combination with a rotatable spindle having an attached bobbin-rest, of laterally-extended resilient bobbin-clutching members bodily rotatable with the spindle, their normally non-engaging free outer ends being adapted to be brought into driving engagement with a bobbin by or through the action of centrifugal force.
4. The combination with a rotatable spindle having an attached bobbin-rest, of resilient bobbin-clutching members fixedly connected at one end with the spindle to rotate therewith, their free and normally non-engaging ends being adapted to move outward by or through the action of centrifugal force into driving engagement with a bobbin.
5. The combination with a rotatable spindle having an attached bobbin-rest, of a plurality of normally contracted spring-arms positively and permanently connected at one end with the spindle to rotate therewith, the free ends of the arms being forced outward by centrifugal action into driving engagement with the bobbin.
6. The combination with a rotatable spindle having an attached sleeve-whirl and a bobbin-rest, of normally contracted resilient bobbin-clutching'means permanently mounted on the spindle above and independent of the whirl, and a bobbin-guide above said means, the latter expanding by centrifugal action to engage and drive the bobbin.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
WILLIAM E. ALLEN.
