SPINNING-SPINDLE.`

SPECIFICATIQN forming part of Letters Patent N0. 671,694, dated April 9, 1901. Application filed October 22,1900. Serial No. 33,806. (N0 mOdeL) i To t/Z whom, t may concern:

Be it known that we, WILLIAM H. GOLD- SMITH and STEPHEN M. HAMBLIN, citizens of the United States, residing at Central Falls, in the county of Providence, State of Rhode 4Island,have invented a certain new and useful Improvement in Spinniug-Spindles, of which the following isaspecicatiomreference being had therein to the accompanying drawings.

Figure l of the drawings shows, partly in elevation and partly in section, an embodiment of our invention. Figs. 2 to 5 show modifications.

Our invention consists, mainly, in forming a spinning-spindle in two parts, one of such parts, termed by us the whi rl part, being provided in practice with a suitable bearing in a spinning-frame and remaining permanently associated with the said bearing in the 'said spinning-frame, and the other of such parts bein termed the skewer it beingin the shape of a detachable spindle-blade and being adapted to be applied to and connected with the whirl part to rotate in unison with the latter during the spinning operation and to receivethe yarn load, the said skewer be- -ing adapted to be detached from the whirl part after having been fully loaded with yarn, it being especially constructed with reference to enabling it to be placed directly into a shuttle for weaving the said detachable skewer, taking in the shuttle the place of the usual spindle, which last is dispensed with.

Having reference to the drawings, l designates the whirl part of our improved spindle. The whirl thereof is designated 2. The said whirl part 1 is or may be in 4practice constructed like the whirl and lower or bearing part of any of the approved makesof spindles. Herein it is shown constructed with a downwardly-extending cylindrical foot p0rtion 3 below the whirl 2, corresponding substantially in shape with the foot portions of spindles now in use, the said foot portion 3 being fitted within an external bearing 4 in a bearing-support 5, the said bearing-support being secured in a hole of the spindle-rail 6 by means of a nut 7 upon the threaded lower end 8 of the said bearing-support in customary manner. 9 designates the usual hook or detent for preventing the whirl part l from becoming accidentally lifted out of the hearing of the bearing-support. The said whirl part l is made hollow or tubular to form an elongated cylindrical central chamber to receive the lower end of the skewer l0. The said skewer mayin practice be formed of any suitable material, but preferably is made of Awood for the sake of cheapness and of lightness,which last is of especial importance when the skewer, with its load of yarn, is placed in a shuttle in order that the said load of yarn may be utilized as weft in Weaving cloth.` The shape of the interengaging portions of the whirl part and skewer may be varied more or less, although preferably we form a tapering bore ll within the whirl part and correspoudingly taper the portion l2 of the skewer which enters the said bore. The fit of the end of the skewer within the bore of the whirl part secures the requisite frictioual adhesion for causing the skewer to rotate in unison with the whirl part during the operation of spinning. If desired, we may increase the said frictional adhesion by slitting the end of the skewer, as at 14 in Fig. 2, in which case the elasticity of the portions of the skewer end which are separated by the slit will be brought into play by the compression which occurs when the skewer end is forced home into the bore of the whirl part. In this case the skewerend will be made a little larger relatively to the diameter of the bore of the whirl part, so as to insure the bending of the said parts of the skewer end toward each other as the skewer end-is caused to enter the bore of the whirl part. When the skewer end is slitted, as just described, the said skewer end need not be tapered and may be left cylindrical, as shown in Fig. 2.

In some cases we may provide a positive lock for compelling the skewer to rotate in unison with the whirl part. Thus in Fig. 3 we have shown a wire or screw 15, driven across the inner part of the bore of the whirl part, the end of the skewer being notched, as at 16, to t over the said wire or screw. The fiat side ofthe notch fits against the side of the said wire or screw.

In some cases we may employ a yielding clip or pressure device to prevent the skewer from rising within the whirl part and becoming IOO loose with reference thereto. Thus in Figif we have shownasplit ring l7,.seated within an internal groove 18, formed in the whirl part. When the skewer end is pushed into the bore of the Whirl part, it preferably expands the said split ring which clamps the skewer end firmly. This device prevents the skewer from coming loose at high speeds of` rotation.

Fig.` 5 shows a form of the invention in which thewhirl part is provided above the whirl with an` extension 19, which is slitted, as at 20, to form a series of elastic tongues. The series of elastic tongues constitute a yieldingclamp to hold the skewer in place.

Preferably we form the skewer double ended, as in Fig. l-that is to say, it is symmetrical, both ends being alike, so thateither end may be entered indifferently into the whirl part, according as the skewer may happen to be picked up for the purpose of being applied to the Whirl part. The skewer is slightly barrel shape-that is to say, is largest in'diameter at about mid-length thereof and gradually contracts in diameter therefromvto the entering ends. The barrel shape of the skewer eliminates tendency of the same to warp, kwhile the double-ended construction eX- fined in the whirl part to escape as the skewer is being inserted into the bore of the latter and pressed home, We form a groove leading to the outer end of said bore in the inner surface of the said whirl part. This groove either mayextend straight along said bore, as -at 24, Fig. 4, or spirally, as at 25, Fig. 5. The -escape of .the air which is permitted by the said groove obviates tendency of the skewer to become forced upward and loosened inits seat within the whirl part by expansion of said air when the Whirl part becomes warm in operation.

We claim as our inventionl. rIn combination, in a spinning-machine, the whirl part havinga downwardly-extending cylindrical Aportion containing anfelongated cylindrical central chamber, an external bearing receiving the said cylindrical portion, and the skewer on which the yarn is received as spun, detachably tting at its lower end Within the central chamber of the said Whirl part for the spinning operation and adapted to be removed therefrom with its load of yarn, substantially as described.

2. In combination, in aspinning-machine, the rotating whirl part, the bearing in which the said whirl part is-permanently mounted, and the wooden skewer on which the yarn is received as spun applied to the said whirl part during the spinning operation, and adapted to `be detached therefrom when the said yarn load, has been completed, substantially as described.

3. In combination, in a spinning-machine, the rotating Whirl part, a bearing with which the said whirl part remains permanently connected, and the double-ended or reversible skewer on which the yarn is received as spun connected with the said rotating whirlpart during the operationof spinning and adapted to be detached therefrom when its yarn load is completed, substantially as described.

4. In combination, in a spinning-machine, therotating Whirl part having the internal boreand the groove forming a vent for air, and the skewer on which the yarn is received as spun tting Within the said bore and detached therefrom when the load of yarn has been completed, substantially as described.

5. A solid yarn-skewer for spinning, e., having the main length thereof shaped to contain a load of yarn wound thereon in the spinning operation, and having the end thereof shaped to enter and Iit detachably the socket of a rotating Whirl,substantially as described.

6. A solid reversible yarn-skewer for spinning, dac., having the main length thereof shaped to contain a load of yarn wound thereon in the spinning operation, and having each end thereof shaped to enter and fit the socket of a rotating w'hirl,snbstantially as described.

7. Ayarn-.skewer for spinning, dac., having thebarrel-shaped body to contain a load of yarn Wound thereon in the spinning operation, and having each end thereof shaped to enter and fitthe socket Vof a rotatingwhirl, substantially as described.

In testimony whereof we affix our signatures in presence of two Witnesses.
