SPINDLE AND RETAINING DEVICE THEREFOR.

SPECIFICATION'forming part of Letters Patent No. 508,235, dated November 7, 1893.

` Application filed .Tune 17, 1893. Serial No. 477,909. (No model.)

To @ZZ wiz/0m.` it may concern.-

Be it known that I, JAMES H. NoETHRoP, a subject of the Queen of Great Britain, residing at Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Spindles and Retaining Devices Therefor, of which the following description, in connection with the accompanying drawings, is a specitication,like letters on the drawings representing like parts.

In this invention I have shown a sleeve whirl spindle, the whirl of which is extended and provided with a retaining device to cooperate with a lip or projection surrounding the lower end of the whirl below the band receiving groove, as will be hereinafter described.

Figure 1, in elevation shows a spindle and bearing embodying my invention. Fig. 2 is a vertical section thereof; and Fig. 3 shows the holder detached.

The supporting-case A having a central tubular portion to receive the lateral bearing a, which may be oi'l anyusual construction, has a threaded shank put through a hole in the rail B where the shank receives a nut A to confine the case in place. The case, as shown, has a' curb A2, thelinner upper edge or lip of which, as best shownin Fig. 2, is shaped to form 'a seat forvthe reception of a holder b, shown separately in Fig. 3, it being adapted to be sprung into said seat, said holder being represented as a split ring composed of wire.

The spindle C has an attached sleeve whirl provided with a cup c to receive the base or lower end of the bobbin d, shown partially by dotted lines, and belowthis cup and substantially continuous with it kis the band-receiving portion c', while below the band-receiving portion the Whirl is terminated by a neck c2 which has an outwardly extended lip or flange so shaped as to leave acontracted portion or space to permit the spindle whirl to be lifted slightly While the holder remains in its seat. The holder b is contracted about the neck c2 and-follows the spindle when the latter is separated from the supporting-case, the

operator, when the spindle is to be so removed, inserting a suitable tool into a hole 2, and by pressure on the holder contracting 5o its diameter sufficiently to disengage it from its seat in the curb. This holder, seat, and neck are shown andclaimed broadly in my PatentNo. 505,721, dated September 26, 1893, and in practice, the holder may be manipulated as provided for in said patent.

As shown in the drawings there is no open space between the portions c and c into which a band could possibly enter and lodge and the band cannot leave the band-receiving por- 6o tion and get onto a smaller portion above and thus materially aect the degree or extent ot twist.

Myfinvention would not be departed from if the cup and portion c were separated, as for instance, the whirl might be separated on the dotted line :n Fig. 2, 011e part being suitably secured to the other, so as not to leave a space into which the band could enter and remain. 7o Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

A spindle having a sleeve whirl composed of a band-receiving portion having substantially continuous with its upper edge a bobbin-receiving cup to thus obviate a space into which the band can lodge, and having at yits lower edge a neck provided with a lip or liange, combined with a supporting-case hav- 8o ing at its interior a lateral bearing for the spindle, said case having a curb or lip with a seat, and a contractible and expansible holder adapted to be sprung into said seat and to follow the said neck'when the spindle is re- 85 moved from its bearings, substantially as described.

In testimony whereof I have signed my name to this speciication in the presence of two subscribing witnesses. Y

JAMES H. NORTHROI. Witnesses:

C. E. LONGEELLOW, S. F. SMITH.
