SPINDLE-RETAINING DEVICE.

Application filed. December 8, 1910.

To all whom it may concern:

Be it known that l, Enasros D. Cnnsnnno, a citizen of the United States, and resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Spindle-Retaining Device, of which the following is a specification.

lVty invention relates to a spindle retaining device, and more particularly to means for retaining the spindle of a spinning or winding machine from unintentional displacement while removing a bobbin therefrom.

In practice, the quick removal of a bobbin has frequently resulted in unseating the spindle from its step, causing delay. My present invention is directed to simple means for preventing such unseating of the spindle and consequent delay, by providing a retaining device which will hold the spindle in its step whatever be the normal lift on the spindle due to the friction between the bobbin and spindle at the moment of removing the bobbin therefrom and which will at the same time in no wise hinder the free rotary movement of the spindle and will admit of the ready removal of the spindle from its step when desired.

A practical embodiment of my invention is represented in the accompanying drawings in which,

Figure 1 is a view in side elevation of a spindle, its whirl and step, showing the retaining device in its relation thereto. Fig. 2 is a top plan view of the same, showing the spindle in section and the flange at the bottom of the whirl partly broken away, and Fig. 3 is a vertical central section of the same.

The spindle is denoted by 1, its whirl by 2 and. the spindle base by 3. The lower end of the whirl is provided with a ledge or flange l extending outwardly therefrom, as the preferred means for placing it under the control of the retaining device. The retaining device preferably consists of a bolt or plunger 5 seated in a horizontal perforation 6 in the upwardly extending end 7 of an arm 8 branching from and formed integral with or fixed to the spindle base 8. The part 7 extends upwardly to such an em Specification of Letters Patent.

tent as to bring the perforation 6 above the flange 4 on the whirl. The belt or plunger 5 1s provlded with two annular grooves.9

and 10, which are adapted to receive the upper arm of a spring 11 made fast to the part 7 and projecting through a slit 12 extending downwardly from the top of the part 7. Then the spring arm 11 is in the groove 9, the bolt or plunger will be held in position with its inner end over the flange 4 so that the whirl 2 andhence the spindle 1 cannot be lifted sufficiently to unseat the spindle. In the event it is desired to remove the spindle, the spring arm 11 may be pressed out of the groove 9 and the bolt or plunger 5 slid outwardly until the spring arm 11 seats in the groove 1.0. For convenience in sliding the bolt. or plunger 5 outward or inward, the adjacent walls of the two grooves 9 and 1.0 are beveled as at 13, I l, so that a positive endwise push on the bolt or plunger will force the spring arm 11 downward. and permit the bolt or plunger to slide until the spring arm is seated in the adjacent groove. The opposite walls of the said grooves are, however, abrupt, so that the bolt or plunger is positively held against displacen'ient from its seat in the perforation 6, unless the spring arm be forced down and held down while the bolt is withdrawn to a point beyond the groove 10.

This simple device is a positive stop against the unintentional. removal of the spindle while permitting its intentional removal.

What I claim is:

1. The combination with a spindle provided with a ledge and a spindle base provided with an arm, of a spindle retaining device seated in said arm in position to slide over the said ledge, the said retaining device beingprovided with a groove having an abrupt side and a beveled side and a spring in position to enter the groove.

2. The combination with a spindle provided with a whirl. having a ledge thereon and a spindle base provided with an arm projecting outwardly and upwardly there from, of a spindle retaining device seated in said arm in position to slide over said edge, the retaining device being provided presence of tWo Witnesses, this 5th day of with grooves spaced apart thereon, and a December 1910.

sprin arranged to enter either one of said groov es to hold the retaining device in either ERASTUS CHESEBRO' looking or releasing position. Witnesses:

In testimony, that- I claim the foregoing B. S. CUTLER, as my nvention, I have signed my name 1n I EDWARD E. 'BRADLEY.
