JOHN B. Nemmeno, or woonsocirn'fr, nno'nie retenir SPINDLE.

`Application filed December 29, 1921. Serial No. 525,806.`

To all-whom it may concern.'

Be it known that I, JOHN B. NAINTEAU, a citizen of the United States, residing at WVoonsoclret, in the county of Providence,

State of Rhode Island, have invented certain` new and useful Improvements in Spindles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in spindles and particularly to spindles used in spinning machines.

One object of the invention is toprovide a construction and arrangement of parts which will insure the retention of. a sufficient quantity of lubricant to require attention only at widely separated intervals, and in which the lubricant will be prevented from being thrown outwardly from the device, by centrifugal force.

In devices of this character the lubricant travels upwardly on the blade of the spindle and then is thrown outwardly, against the inner face of the whirl, from whence it runs down and is thrown outwardly from the lower edge of the whirl. It is the particular object of this invention to so construct the A blade and socket in which the lower end of the blade is disposed as to cause the lubricant to be thrown against the inner face of the socket, from whence it returns to the felt lubricant washer.

Also, the wall of the socket has heretofore been formed with a downward taper at its lower end, and cylindrical near its upper end, with the result that the space around the lower tapered end of the blade is narrower at its upper end than at its lower end, thus causing the bulk of the oil to remain in the lower portion of the socket, and prevent proper distribution of the oil tot the other portion of the blade. In the present invention the oil space in the socket is enlargedV throughout its length so that a maximum quantity of oil will be retained therein and the blade more properlyy and equally lubricated.

Other objects andadvantages will be apparent from the following description when taken in drawing; i

In kthe drawing: f. The lfigure isa vertical longitudinal sectional View,y *through a ,spindle showing the invention.4 A

connection with the accompanying Referring particularly to the accompanying drawing, 10 represents the base of the spindle, which has thel upwardly extending reduced tubular extension 11. The boreof l this extension extends downwardly into the base, as shown at 12, where it is tapered, and y has. its .upper `portion cylindrical and cut comparatively .deep into the -wall'of the eX- tension, as shown at 13..V Screwed onto the upper end of the extension 11 is a cap 141:, which has its upper endformed with an inwardly directed flange 15, the inner face of said ange being undercut or beveled, as shown at 16, to engage with the upper end of the extension. The sleeve 17, of the whirl, fits down over the extension 11, 'and has the blade 18 disposed longitudinally and centrally therethrough.

The lower end portion of the blade 18 is tapered and fits into the tapered portion 12,

of the bore of the base. The portion of the blade, from the upperend of the tapered portion, to the upper end of the sleeve 17, of the whirl, is cylindrical, as clearly seen in the drawing. It will be noted that the oil recess 13 is of a length toy extend throughout the greater part of the tapered portion of the blade, with the result that a larger quantity of oil will be retained therein, than in the recesses ordinarily provided. The upper end of the base 10 is formed with the usual cup 19 in which is disposed the felt washer 20, for retaining the oil, a channel 21 being formed from the bottom wall of the cup downwardly and inwardly into the recess 13, a metal washer 22 being disposed on the upper end of the cup, over the felt washer.

The upper end of the extension 11 is bored out to form the shoulder or ledge 23, and formed downwardly and inwardly, in the wall of the extension, from` the upper face of the shoulder to a. point above the cup 19, is a channel 24.

`Secured to and encircling the portion of the blade 18, immediately below the upper end of the sleeve lof the whirl, is a band or collar 25, which, when the blade and whirl are properly disposed with relation to the extension of the base, lies below the beveled mouth of the cap 14, so that the oil which travels upwardly on the outer face of the blade will be thrown outwardly against the upper end of the interior of the extension 11, from whence it will run down through the channel 24, into the recess 13, and spread on the adjacent portion of the blade.

rIhe lower end of the sleeve 17, of the whirl, is formed with a peripheral flange 17', in the upper face of which is formed a circu lar groove 26, for the reception of' the bill 27 of the hook 28, which hook is pivotally carried by the base. Thus, as the whirl rotates, and has a slight tendency to rise, the bill of the hook will be retained in the groove,'so that all danger or" the hook being released is obviated.

By this construction a larger quantity of oil will be reta-ined in close proximity to the blade of the spindle than in spindles heretofore, and also the oil will be prevented from passing upwardly along the blade by reason of the collar 25. This arrangement also prevents the oil from being thrown outwardly against the inner face of the whirl, from whence it would reach the lower end of the whirl, and be thrown outwardly from the flange 17. Furthermore, the loss of time, in oiling spindles, is reduced to a minimum, and the quality of the product improved.

What is claimed is:

1. A spindle for spinning machines including a base, a blade mounted within the base and having a whirl, a collar upon the blade within the whirl, and a flanged cap mounted upon one end of the base and encircling the collar.

2. A spindle for spinning machines including a base having open and closed ends, ablade mounted within the base and having a whirl, a collar upon the blade within the whirl, and a flanged cap mounted upon the open end of the base with its flange positioned exterorly of the collar.

3. In a spindle, the comb-ination with the base, the blade having a collar, and the whirl, of a flanged cap on the upper end of the base surrounding the collar to prevent lubricant being thrown against the whirl.

4. In a spindle, the combination with the base, the whirl and blade, the latter having a collar within the whirl, of' a flanged cap on the upper end of the base with its flange surrounding the collar above the lower face of said collar.

In testimony whereof I affix my signature.

JOHN B. NAINTEAU.
