CAP-SPINNING FRAM Application filed J'u1y'13, 1922. Serial: No. 574,676.

T 0 all whom it may concern:

Be it known that I, JOSEPH H. JONES, a citizen of the United States, residing at Winthrop, in the county of Suffolk, State b of Massachusetts, have invented a certain new and useful Improvement in Gap-Spinning Frames, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention comprises improvements in cap-spinning devices of the class in wh ch a live cap and the spinning element (spindle or bobbin) with which it cooperates revolve in unison, or substantially in unison. I

The invention comprises improvements in connection with the so-called pivot, i. e., the element which in devices of the class referred to serve to afford vertical support to the revolving cap and to control the said'cap during'the traverse by means of which the yarn 1n process of being spun is distributed upon the spinning element, as it is wound during the spinning operation.

The invention provides a novel arrangement of a so-called pivot in combination with a live cap. Also special means for mounting the pivot and supporting it in working relations with the cap with which it cooperates.

An illustrative embodiment of the features of the invention is illustrated in the accompanying drawings, in-which,--

F ig. 1 is a view ofcertain parts of a spinning frame having the said illustrative embodiment combined therewith, the parts being viewed at an angle.

Fig. 2 is a plan view showing two sets of bobbins, live caps and so-called pivots, and a portion of the pivot supporting rail.

Fig. 3 isan elevation of portions of a spindle, a bobbin with its yard load, a live cap cooperating with said bobbin, a socalled pivot cooperating with thersaid cap, and a portion of the pivot supporting rail.

Fig. 4 is aview of certain of the parts shown in Fig. 3, showing the mounting or support for the so-called pivot in longitudinal vertical section. 3

Referring first to Fig. 1: Such figure shows at 1 a portion of a thread-board having hinged thereto at 2 a block 3 (one of the usual series) carrying a'guide 4 for the yarn a: between the front rolls and the twisting devices, 5 being a spindle-railhaving mounted thereon in usual manner-a ear1ng'.-support spinning-spindle 71., At 9 is a quill or bobbin mounted upon the spindle-blade, and at 91 a load of yarn which has been spun and wound upon the said quillor bobbin. gAt 10 is a revoluble or live cap cooperating with the said quill or. bobbin. A so-called pivot or cap-controlling wheel is shown at l1. 12 is the mounting'for. the said pivot orv cap-controlling wheel, 13 being a rail to which the base 121 of the said mounting is fitted. j

s usual in the case of devices of this type the-cap 10 has a bushed hole through itshead, with. a central opening so proportioned that the bushing has a close but easy sliding fit upon the blade or barrel of the; spinning element to which the cap is applied, such element being in this instance the quill-or bobbin 9. The said sliding fit permits vthe ca to gravitate downward upon the said .b adev or barrel until the cap is supported vertically through engagement of its flaring peripheral portion- 101 with a the engaging. portion of the associated pivot 0r cap-controlling wheelll. The said sliding fit also permits the traverse movements of the cap up and. down upon the said blade or barrel which are required to take place for the distribution of the twisted yarns uponsuch blade or barrel in being wound thereon. The cap is caused to revolve through light frictional contact between the periphery. of the said blade or barrel and the inner surface of the bushin in connection with the hole through the head of: the cap. 1 Referring now to the features of the invention: The pivot or cap-controlling wheel 11 is arranged to rotate in a -plane at an anlower portion of the pivot or cap-supporting wheel is located adjacent the lower edge or lip; f the cap, as appears in Figs. 1 and 3.

referably, the lower portion of the pivot or cap-supporting wheel extends generates'currents of air also movlng oppositely. These currents of air act against the portion of the yarn being spun which extends around the lower edge or lip of the cap to the spinning element, so as to offer a slight resistance to the revolution of such portion ing wheel is supported of the yarn in unison with the spinning element, thereby producing what is termed drag of a character which promotes winding of the yarn upon the spinning element. This improves the spinning operation and facilitates the production of a softer yarn than the earlier arrangement of revoluble caps and their supporting pivots.

A second feature of the invention is the employment of a supporting bearing of ball or roller-bearing type for'the pintle 111 of the pivot or cap-supporting wheel. In the present instance I have shown a roller-bearing, although as will be obvious to those skilled in the arts of spinning and ball roller-bearings, ball-bearings may be used in place of the roller-bearings. In the illustrated instance the mounting or support 12 is of sufficient internal dimensions to accommodate a series of

anti-friction rolls

112, 112, etc. Fig. 4, which are engaged at their opposite ends in notches in a pair of

cagerings

113, 113, the assemblage of rolls and rings constituting a cage. The pintle 111 of the pivot or cap-supporting wheel is fitted interiorly within the circular series of rolls and revolves therein, the cage being itself revoluble within the mounting or support 12. Thereby the pivot or cap-support- I vertically and the said wheel in turnis enabled to afford support vertically to the cap with which it cooperates. To take care of the end thrust which is outward away from the axis of the spinning element, I employ a ball 114,

Fig. 1, which is disposed properly crate with the outer end of the pintle. At 115 is a coil spring located in a pocket at the outer end of the mounting or support 12 and confined between the outer end wall of the said pocket and the end-thrust ball 11 1. I use this spring to give ayielding and cushioning action, and to press the pivot axially to maintain its lateral engaging edge in engagement with the flaring portion of the cap. At 116 is a split ring of wire occupying a groove in the pintle and serving the functions of (l) preventing the to coopwithdrawal of the pintle, and (2) of a splash ring to cause oil working along the pintle toward the so-called pivot or wheel at the inner end of the pintle to flash off under centrifugal action, whereby such oil is prevented from passing out at the inner end of the bearing support.

To provide for radial adjustment of a pivot, the mounting 12 is made separate from base 121, and provided with a foot 122, having a slot 123 for the stem of a screw 12 1 which attaches the mounting to the base. This slot permits the said radial adjustment. By means of such adjustment the height of the cap above base 121 may be varied as found necessar-v lVhat is claimed as the invention is 1. Cap-spinning devices comprising a revolving spinning element, a live cap revolving substantially in unison therewith, and a supporting wheel or pivot with which the cap is in external peripheral contact, revolving on an axis in a plane at an angle with the horizontal.

2. Cap-spinning devices comprising a revolving spinning element, a live cap revolving substantially in unison therewith having a peripheral upward flare, and a supo-rting wheel or pivot which is engaged by the flaring portion of the cap, revolving in a plane at an angle with the horizontal.
