This invention relates to material handling apparatus and more particularly 'to. machines having interchangeable material supplyor take! up means which aremounted on spindles or the like to'be both rotatable on their own axes and revoluble about another axis not parallel thereto. In machines of such kind the supplyrortakeup spools or the like are often-subjected to. cycli.-. cally varying and even cyclically reversed centrif- 1 ugal stresses having a' componentin the direction of the axis of the spool. These are effective to rack the. bearings on which the spoolturns as strand is drawn therefrom, tend tovarynthe resistance of the spool to turning andthusim-L 3 pose a varying tension upon the strandmbeing drawn therefrom, and also tend toxloosen .the

-means whereby the reels-are attached to 'the.

3 0 tional resistance to the withdrawal of their strands at the moment when the other pair is least affected. J 'It is anobject of the present invention to provide a simple, strong and effective mounting for a rotatable element which shall permit of quick and easy interchange of elements mounted thereon and which shall be affected to a minimum extent by varying stresses along the axis of rotation. l

'With this and other objects in view an illus trative embodiment of the invention comprises a spindle withdrawably mounted in a bearingiat either end, the bearings being carried by any 'desired framework. The spindle is free both to rotate and to slide axially in one of the'bearings, but means., are providedatthe other bearing to prevent axial'motion of the spindle therein while permitting freedom of rotation. These latter meansare releasable to permit of withdrawal ofthespindle for interchanging a'spool mounted thereon." E A Other objects and characteristic features of'the inventionwill clearly appear from the following detailed description. of illustrative embodiments i thereof: .takfln in. connection with the accompanyingdrawings in which the same reference numeral'sare applied to identical parts figures and in which i Fig.1 is a diagrammatic'view of a supply spool carrying yoke of a cable making machine em-"- bodying'the invention; 1 Fig. -2' isa {detached enlarged broken view in central longitudinal-section of the spool, spindle and mountings ofFig. 1'; --Fig.'3''is asimilar view of a modified form; '-Fig."4- is a transverse sectional view on the line- 4- lof Fig. 2, and' Fig. 51s a similar view Fig.3.; I

"A sleeve I1 is mounted freely on thejspindle l6 nearits lefthand end (Fig. 2), and'is providedv with a coneat' the right to enter the central bore or the'spool l5to support the left'end of ,the same.

The right hand sleeve like extension of the wheel is formed with a circumferential groove 32 to receive the latch 28 which prevents any accidental displacement of the spindle.

The right end of the spool I5 is supported on the conical left hand end of a sleeve 33 on the right hand end of the spindle I 6. The main body of the sleeve is cylindrical and is freegto slide and to rotatein abearing 34 mountedin the yoke H.
