Divided and this application June 3,

1950, Serial No. 165,910

2 Claims. 1

This invention relates to spindles as used in textile machines such as spinning frames and twisters, and is a division of my prior application Ser. No. 98,305 filed June 10, 1949 and issued January 2, 1951 as Patent No. 2,536,618.

In recent practice, the spindles in such machines have been substantially increased in length, and the length and weight of the yarn packages produced thereon have been correspondingly increased. I

It is the general object of my present invention to provide an improved spindle construction which is well adapted for use with these longer and heavier yarn packages, and which is "strongly resistant to accidental deformation, particularly during the doffing operation.

A further object of the invention is to provide an improved spindle which may be manufactured at a substantially reduced cost.

My. invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawings, in which Fig. 1 is a side elevation of my improved spindle, with the spindle rail and yarn tube shown in section; and

Fig. 2 is a sectional side elevation of certain parts shown in Fig. 1.

Referring to the drawings, I have shown a spindle adapted for use in a spinning or twisting machine and comprising a base It! which may be secured in a ring rail. or other supporting structure H by a clamping nut l2. The base may be provided with the usual oil tube l4 and doffer guard l5.

My improved spindle as shown herein comprises a thin steel tube 40 which is closely fitted outside of a filler piece or bushing M, which in turn is seated on the tapered upper end 42 of a spindle blade 44.

The upwardly extending sleeve portion 45 of a driving whirl 46 is firmly fitted about the lower end of the steel tube 40. The whirl 46 and sleeve 45 are preferably integral and are commonly formed of steel. The sleeve 45 reenforces and strengthens the lower end portion of the tube 40. The upper edge of the sleeve 45 is outwardly and downwardly beveled to facilitate the placing of yarn tubes thereon.

The bushing 4| may be formed of a light metal, such as aluminum or magnesium, and is recessed to receive the tapered upper end portion 42 of the blade 44. The blade 44 has the usual bearing l and is commonly formed of hardened steel.

The tube 40 is of full size to its extreme lower 1949, Serial No.

2 end. A plug 50 is inserted in the open upper end of the tube 4|] to close the opening and to prevent the accumulation of lint and dirt therein.

,This plug 50 is smoothly rounded and has its outer surface aligned with the outer surface of the tube 4|]. The plug may be of any suitable material and is preferably recessed at 52 to reduce weight.

The plug frictionally engages the upper end portion of the yarn tube T as indicated at A (Fig. l) and the lower end of the yarn tube T is loosely centered by the sleeve 45 as indicated at B. The tube T may be of fibrous or plastic material.

The construction shown herein has many advantages, and the use of steel tube 40 provides much increased strength and stiffness, particularly when the tube is clamped between the sleeve 45 and the bushing 4|.

Having thus describedv my invention and the advantages thereof, 1 do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

1. In a spindle for supporting and rotating 9. yarn carrier, a one-piece steel blade having an enlarged upper end portion, a barrel comprising a thin steel tube which carries its full diameter to its extreme lower end, a bushing firmly fixed in the lower end of said tube and having a recess in which the enlarged upper end portion of said blade is received and firmly engaged, a cap 7 closing the upper end of said tube and engaging and centering said yarn carrier at its upper end only, and a driving whirl of a strong metal, which whirl has an upwardly-extended sleeve which encircles and firmly engages the lower end portion of said steel tube, said upwardly-extended sleeve also loosely centering the lower end portion of said yarn carrier and holding said lower end portion spaced outwardly from said tube.

2. In a spindle for supporting and rotating a yarn carrier, a one-piece steel blade having an enlarged upper end portion, a barrel comprising a thin steel tube which carries its full diameter to its extreme lower end, a bushing firmly fixed in the lower end of said tube and having a recess in which the enlarged upper end portion of said blade is received and firmly engaged, a cap closing the upper end of said tube, and a driving whirl of a strong metal and which has an upwardly-extended sleeve which encircles and firmly engages the lower end portion of said steel tube and which is of greater outside diameter than said tube, and said tube being firmly clamped between said sleeve and said bushing.
