Application filed'November'lG, 191.9. Serial N0. 336,897.

To allwlzomz't'may concern:

Be it known that I, Josnrrr H. JoNns, a citizen of the United States, residing at \Vinthrop, in the county of Suffolk, State of hlassachusetts, have invented a certain new and useful Improvement in Cap-Spin ning Frames, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to cap-spinning devices of the class in which a cap and the spindle or bobbin with which it'cooperates revolve in unison.

It provides in a novel manner for con trolling a cap vertically, throughout the. spinning process, and during the relative traversing movements, between itand its cooperating spindle or bobbiinby which the twisted yarn in being wound upon the spindie or bobbin is distributed thereon, so as to be built up into the required form of yarn-mass.

It consists in a simplified and improved construction and combination of a cap and its controlling means, by which wear of the parts is reduced and practically eliminated, and better results are secured in the spinning.

The drawings show an illustrative embodiment of the invention, which is also the preferred form of embodiment.

Figure 1 of the drawings is a view of certain parts of a spinning frame, illustrating the said embodiment, the said parts being shown mainly in front elevation but with one of the caps in transverse section in a vertical plane.

Fig. 2 is a view looking from the right hand side in Fig. 1, with the rails in vertical cross section.

At 1, Fig. 2, is a portion of a thread-board having hinged thereto at 2, in usual manner, the guides f for the yarns between the front rolls and the twisting devices. At 5 is spindle-rail having mounted thereon in usual manner bearing-supports 6 of spinning-spindles 7, in this instance of the well-known sleeve-whirl type, driven by means ofbands 8 encircling the whirls 7. At 9 are quills or bobbins mounted upon the spindle-blades. At 10 are revolving caps cooperating with the said quills or bobbins. At 11 (F 2) is one of the cap-controlling wheels, it coacting with the adjacent cap in the manner explained hereinafter; at 12 is a mounting for the without any sliding wheel 11; and at 18 is a rail supporting the mountings of the series of wheels 11 cooperating with the series of caps 10.

The caps 10 have the holes through their heads hushed as at 14, Fig. 1. The central openings of the bushings are so proportioned that the bushings have a close but easy sliding fitupon the blades or barrels'of the spinning elements to which the caps are applied, such elements being in this instance the quills or bobbins 9. The said sliding fit permits the caps to gravitate downward upon the said blades or barrels until they are supported vertically through engage 11, and also permits the traverse movements of the caps up and ment with the wheels down upon the said blades or barrels which are required to take place for the distribution of the twisted yarn upon such blades or barrels in being wound thereupon. The caps are caused to revolve through light frictional contact between the peripheries of the said blades or barrels and the inner surfaces of the said bushings.

eferring now to the features of the invention Important characteristics of the invention hat will be apparent from Fig. 2 of the drawings are, first, that during operation the contact that takes place between a revolving cap 10 and its controlling wheel 11 is purely a rolling peripheral contact contact and resulting frictionand wear such as are found in the case of earlier devices; and, second, that the cap is controlled vertically by the said peripheral contact; The principle of construction that is utilized in securing the said rolling peripheral contact, accompanied by the said vertical control of the cap, consists in making one of the two elements in question cone-shaped, and arranging it so that the longitudinal line of its surface which contains the point at which contact with the other member takes place, inclines upwardly toward the prolongation of the axis of the wheel. In simple terms, the essential relations of the cone-shaped member and coacting wheel are such that a peripheral portion of the cap overhangs a peripheral portion of the wheel, but "without vertical contact between any portion of the cap and a horizontal surface of the wheel. The gravitating tendency of the cap operates to keep the overhanging peripheral portion of the cap in contact with the peripheral Wheelportion that it overhangs. The resting of the said overhanging portion of the cap upon the portion of the wheel with which the peripheral contact occurs provides for the support of the cap vertically by 'means of thewheel, and in Obvious manner secures the'control of the cap by the wheel in the traverse movements by which the distribution of the twisted yarn is effected in building up the yarn mass. 7 I

In the operation of a spinning frame in which the invention is applied, the said traverse movements may be communicated to either the rail 13 or the spindle-rail 5, as may be preferred, usually the former. In a rising movement of rail 13 and wheel 11, for example, the contact of the periphery of the wheel 11 with the upwardly flaring periphery of the cap shown in the drawings will operateito move the cap 10 upward along the blade or barrel of the quill or bobbin 9, while iii-the descending movement of 7 said. rail thecap will accompany the wheel in substantially downward, its periphery keeping practically in touch with that of the wheel.

The gravitating conjunction withthe conicalshape of one of the two members and the described overhanging of the cap-periphery with relation to the wheel-periphery, have the effect of rendering the cap automatic in finding itsproper working relations with the wheel 11 and keeping continuous contact therei with. Hence the control of the position of gravitating cap in seeking and maintaining Y the cap is maintained continuously, and the proper distribution of the twisted yarn upon the quill 9 is insured.

Delicate adjustment its cap, the purpose of insuring any exact distance between the axes of the two, being rendered unnecessary by the automatic action of the of the spindle 'and the required peripheral contact with the h l 11; consequently",

, w in revolving around the axis of the spindle, quill, or bobbin,.and cap, will pass easily between the periphery of the cap 10 and that ofthe wheel 11.. There is no tendency to detain the yarn between the cap and wheel, and there is no injurious action upon "the the I wheel is a tendency of the cap, in

and of the wheel 11 is not needed for any slight variation forwardly or rearwardly 1n the setting same,

from Fig. 2, the

bal-

construction without involving a departure from. the invention.

One efi'ect of the engagement of the conical periphery of the cap with theperiphery of tendency to press the cap bodilv away from the wheel, and to tilt the cap slightly in a vertical plane. The next result of this tendency is a closer engagement of the bushing 14 of the cap with the blade or barrel of the spinning element 9, operating to insure rotation of the cap in unison with said element, which is particularly advantageous in starting at the spinningframe after a stoppage.

lVhat is claimed as the invention is,--

1. In spinning devices of the revolving cap class, the combination with a revolving spinning element, of a cap mounted upon the blade or barrel of said element, revolved thereby and movable longitudinally thereof, and a wheelfor said. cap controlling the latter in the traverse movements, said cap and wheel having purely rolling peripheral contact between the tapering periphery of one thereof and the periphery of the other, one of them being cone-shaped, and with a peripheral portion of the cap overhanging a peripheral portion of the wheel.

2.. In cap-spinning devices, in combination, a revolving vertically gravitating cap, and a controlling wheel therefor, one of said elements cone-shaped, with a peripheral portion of the cap overhanging the wheel, and with purely rolling peripheral contact be tween the tapering periphery of one of. said elements and the periphery of the other thereof.

3. In cap-spinning devices of the revolving cap class,the combination with a revolving spinning element of a cone-shaped upv wardly flaring cap mounted upon the blade or barrel of said element, revolved thereby, and movable longitudinally thereof, and a controlling wheel for the said cap, in purely rolling peripheral contact with the latter.

In testimony whereof I afiix my signature in presence of two'witnesses.
