XMM/I/QMJA UNITED STATES PA'rmvT OFFICE.
WILLIAM DRAPER, OF HOPEDALE, MASSACHUSETTS, ASSIGNOR TO DRAPER COMPANY, OF PORTLAND, MAINE, AND HOPEDALE, MAS- SACHUSETTS, A CORPORATION.
SPINNING-SPINDLE.
SPECIFICATION forming part of Letters Patent No. 686,446, dated November 12, 1901.
Application filed June 5, 1901.
To all whom it may concern:
Be it known that I, WILLIAM F. DRAPER, a citizen of the United States, and a resident of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Spinning-Spindles, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
This invention relates to spinning-spindles; and it has for its object the production of novel means for maintaining the yarn-carriers or bobbins at a definite level on the spinningframe and also to provide a novel coupling or device for connecting the bobbin to the spindle to be rotated therewith. It is objectionable in all cases to have the traverse vary on the bobbins, so that the yarn is not wound alike thereon; but it is particularly obj ection able with the filling-carriers or bobbins such as are used on Northrop automatic looms, for if in spinning the bobbins are not properly seated on the spindles the yarn may run down over the rings near the base of the bobbin, when it is sure to be broken in weaving off, the bobbin being held in the shuttle by the rings. To cooperate with the ordinary spindle and cup, the bobbins have to be very carefully reamed out and fitted, allowing very little leeway for the swelling which is liable to take place, as the bobbins are generally moistened while the filling is being moistened. Bobbins thus swollen will not fit down over the spindle-whirl extension, and the vertical position of the bobbin on the spindle will not be the same as under other circumstances, so that the yarn will not be accurately laid thereupon.
In accordance with my present invention the inner fit of the bobbin on'the spindle is purposely made loose, and the requisite leeway for the outer diameter of the bobbin-base is provided by an elastic or expansible coupling or connection between it and the spindle. I have also provided a fixed stop on the spindle to engage the lower end of the bobbin and definitely position the latter longitudinally of the spindle.
Figure 1 is a side elevation of a spinningspindle embodying one form of my invention,
Serial No. 63,1 '75. (No model.)
a yarn-carrier or bobbin being shown in position on the spindle. Fig. 2 is an enlarged vertical sectional detail throughthe base of the bobbin, the coupling device being also shown in section; and Fig. 3 is a perspective view, also enlarged,of the coupling device detached.
The spindle S, the bolster-case A, to receive the pintle of the spindle and held in place on the spindle-rail R by a not B, Fig. 1, and the sleeve-whirl W, fast on the spindle and having the upturned hub or extension w, may be and are of usual construction.
The yarn-carrier or bobbin 0, longitudinally bored to receive the spindle-blade and having the usual rings o around its externally-tapered base 0, is in my present invention reamed out at o to loosely fit the extension w, so as to allow for swelling of the bobbin.
Referring to the drawings, the spindle has rigidly secured thereto above the whirl a metallic cup-like holder D, which surrounds the extension to, (see Fig. 2,) the upturned and slightly-flared annular wall (1 of the holder being shown as turned over and downward within the cup, as at d, to form an annular coupling,which is slit upwardly from its lower edge, as at d Fig. 3. The slitting provides for elasticity or expansibility when the bobbin-base is inserted therein, the coupling frictionally engaging and gripping the bobbin exteriorly, and thereby connecting it with the spindle to be rotated therewith.
The bottom of the cup-like holder presents a fixed annular stop (1 for the lower end of the bobbin to abut against, so that the bobbin is definitely positioned or supported relatively to the length of the spindle, (see Fig. 2,) so that the bobbin will always be fixed as to its vertical position.
It will be manifest that the externally-acting coupling will accommodate itself to the diameter of the bobbin, allowing for shrinkage or swelling thereof.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
A rotatable sleeve=whirl spindle, an up turned cup secured thereto above the whirl, the cup being bent over and downturned at its upper edge and split in such downturned In testimony whereof I have signed my portion to form an annular expansible coupname to thisspecification in the presence of 10 ling wholly within the cup, and a detachable two subscribing witnesses.
yarn-carrier or bobbin longitudinally bored to receive the spindle-blade, the coupling WILLIAM DRAPER' frictionally engaging the base of the bobbin, Witnesses: e
the latter being limited in its vertical position GEORGE OTIS DRAPER,
by the bottom of the cup. ERNEST W. WOOD.
