2 Claims.

The present invention relates to textile bobbins, spools and the like, and is more particu larly concerned with a new and improved type of spindle bushing designed for insertion within a bobbin to engage and center the spindle adj acent its upper end.

The purpose and object of the invention is to provide a new and improved form of bushing which may be readily assembled within the spindle bore of the bob-bin, and serve to engage and prevent vibratory movement of the spindle with respect to the bobbin mounted thereon.

With this and other objects in view, the various features of the invention consist in certain novel features of construction, combinations and arrangements of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art from the following description.

In the accompanying drawing illustrating the preferred form of the invention, Fig. 1 represents an elevation partly in section of a bobbin employing the improved type of spindle bushing at the upper end; Fig. 2 is an enlarged sectional view of the construction shown in Fig. 1, illustrating particularly the upper end of the bobbin with inserted bushing; and Fig. 3 is a detail illustrating a top plan view of the bushing upon an enlarged scale.

Referring particularly to the illustrated embodiment of the invention, a bobbin of generally conventional form is illustrated at I0, this bobbin having an enlarged spindle-receiving bore l2 extending throughout the major portion of its length and terminating in a shoulder 14. The bobbin is provided with the usual metallic ferrule II at the mouth of the spindle bore at the lower end. The spindle indicated generally at I6 is provided with a shoulder l8 and a reduced upper end 20 of smaller diameter.

It is the purpose of the present invention to center the adjacent portion of the bobbin with respect to the upper end of the spindle to prevent vibration or chatter of the spindle relative thereto. I have discovered that this may be accomplished by providing a bushing indicated generally at 30, and made in such a form that it may be assembled and locked within the bore of the bobbin and provide a reduced central portion engaging and centering the upper end of the spindle with a clutch fit. As will be noted in Fig. 2, the enlarged spindle bore l'2 terminates in a shoulder l4, and the prolongation of the bore beyond the shoulder indicated generally at 32 may be smaller in diameter and designed to receive the bushing 30. This bushing, as indicated clearly in Fig. 2, comprises a tubular metallic shell of pressed or drawn metal, having an outer and generally cylindrical body portion 34 which fits within the bore 32 of the bobbin, and seats at its lower end against a shoulder 36. The upper end of the cylindrical body portion is turned outwardly to a slight extent at its rim, and is serrated or equivalently formed at 38 to engage and lock within the wall of the spindle bore. To facilitate insertion and locking of the bushing the bore is provided with a shallow circumferential groove 42.

With this construction the bushing may be assembled within the spindle by slipping in from the upper end and springing the out-turned rim into the locking groove 42. The bushing at its opposite or lower end is turned inwardly and upwardly to provide a centrally disposed collar 44, formed integrally with the outer body portion at 4B and slotted at 48 to form a series of independent and somewhat resilient tongues designed to engage and grip the spindle.

With this construction the upper and reduced end of the spindle extends through the centering collar 44, and is gripped and centered thereby to effectually avoid vibratory or chattering movement with respect to the bobbin as a whole. Locking of the bushing within the bobbin is facilitated through the provision of a multiplicity of projections 50, as shown three in number, which when the bushing is assembled engage and slightly penetrate the engaging seating surface of the bobbin at 36 to effectually prevent turning movement of the bushing with relation thereto.

It will be evident to those skilled in the art from the foregoing description that the present invention, although particularly shown in connection with bobbins of conventional type, it may be likewise applied to textile spools and the like which may be connected with a spindle or arbor for driving purposes.

What is claimed is:

1. A textile bobbin or the like, having a spindle-receiving bore provided with a seating shoulder formed in the upper portion of the spindle bore and a circumferential groove formed in the spindle bore and spaced above the shoulder, and a metal bushing of generally resilient construction having an outer tubular body with an outturned and resilient upper rim, an inner tubular spindle collar spaced from the body and formed integrally therewith at the bottom, the collar being designed to resiliently engage with the spindle and be centered thereby, the bushing I integrally therewith at the bottom, the collar being designed to resiliently engage with the spindle and be centered thereby, the bushing seating at the bottom upon the shoulder and engaging and looking with the resilient outturned rim within the circumferential groove, and holding projections at the bottom portion of the bushing for engaging and partially penetrating the seating shoulder to aid in looking the bushing against l0 turning movement with respect to the bobbin.
