Patented Apr. 12 1932 UNITE STATES PATENT oases JOSEPH A. CLAPIP, OF LAWRENCE, MASSACHUSETTS SPINNING RING MOUNTING Application filed April 30, 1931. Serial No. 533,919.

In drawing, spinning, and twisting frames and the like, employing the customary series of spindles and corresponding series of travel ler or spinning rings, it is essential to satisfactory work that the several rings be accurately centered with respect to the corresponding spindles, and also that the axes of the respective rings and spindles be alined or brought into coincidence. It has been found practically impossible to accomplish this in the original construction of the frame without involving prohibitory expense, so that an independent adjustment of the several rings with respect to their spindles is neces- 15 sary. Previous attempts to accomplish this result have been only partly and indifferent ly successful, have failed to provide for the alinement of the ring and spindle axes as well as the relative centering of their parts, have introduced complicated and expensive structures, including the use of separate ring carriers and multiple ring rails, have been such as to limit the center spacing of the rings and spindles, and have been insufiiciently substantial to produce satisfactory work.

The present invention has for its object to provide a simple and inexpensive adjustable ring mounting which will efiectually meet all of the requirements of such a device, which provides for all of this adjustments necessary with minimum trouble and expense, which requires no substantial change in existing frame structures, which does not unduly limit the spacing of the rings and spindles, which 1nvolves no substantial multiplication of parts,

and which is sufiiciently sturdy and substantial to permit the execution of the most exacting work.

The more particular objects of the invention, together with means whereby the same may be carried into effect, will best be understood from the following description of a preferred embodiment thereof, and its mode of operation, illustrated in the accompanying It will be understood, however, that the particular construction described and shown has been chosen for purposes of exemplification merely, and that the invention, as defined by the claim hereunto appended,

may be otherwise embodied and practiced without departure fromits spirit and scope.

In said drawings: I j Fig. 1 is a plan view and Fig. 2 is a side elevation of a portion of the ring rail of a spinning or twisting frame, showing the spin- 1 dles associated therewith. f v

Fig. 3 is a section taken substantially on the line 3 -3, Fig. 1. v H

Fig. 4 is a view similar to'Fig. 3 illustrating, in exaggerated form, the mode of alining the axes of a ring and itsspindle.

Fig. 5 is a detail and likewise exaggerated section taken substantially on the line 5-5, Fig. i. j v y In the drawings, lO denotes the ring rail and 11 the corresponding spindles. The ring rail isprovided with a plurality of openings 12 corresponding in number and arrangement to the spindles 11. Seated in each of the openings 12 is a ring 13 having unitary, radially projecting ears 14 which engage the upper face of the rail 10 and are secured thereto by suitable fasteners, preferably in the form of cap screws 15 provided with washers 16, extending through apertures 17 in the ears 14, and entering suitable tapped openings in the face of the rail. The openings 12are of greater internal diameter than the external diameter of the rings 13, and the apertures 17 in the ears 14 are considerably larger than the screws 15 to nrovide a corresponding relative movement between these parts when the screws are loosened. Accordingly,'by loosening the screws 15, a universal adjustment of the several rings in the plane I of the face of the rail is permitted, whereby ,the several rings may be accurately centered though said ears may, if more convenient, be made separately and permanently secured to said rings, so as to constitute a unitary part thereof, as by soldering, welding, or otherwise. In any event, said ears areof substantial thickness, thereby providing a sturdy and rigid construction, affording adequate :support for the rings on the rail, and also permitting the accurate alinement of the axes of the rings with those of their respective spindles notwithstanding any irregularities in the attaching face of the rail or lack of exact perpendicularity of said face at any point to the axis of the adjacent spindle. In Figs. 4 and 5, the line A B represents the axis of the spindle 11 and the line XY a perpendicular drawn to the adjacent upper face of the rail 1-0 at the center of the ring 13, this line therefore representing the original axis of the ring when supported by the ears 14L on said face. If these lines are not coincident when the ring and spindle are centered by the adjustment 7 above described, they are brought into coincidence by a differentialangu'lar:variation of the bearing of the ears 141 on the rail 10, as by differentially reducing the rail-engaging faces of one or both of the ea-rs, preferably by grinding, the substantial thickness of these cars permitting this operation without impairment of the rigidity of the structure. Such grinding or reduction of the ears may be either longitudinal of the latter,-as indicated in Fig. 4;, or transverse thereto, as indicated in Fig. 5, or both, depending upon the nature of the irregularity of the rail thereby providing for the universal adjustment of the axis, or its adjustment in two perpendicular planes.

It has been found in practice that a spinning frame embodying and practicing the invention above described is capable of producing workwhich it has been commercially impossible to produce on any spinning frame as heretofore constructed, the accurate relative positioning of the rings and spindles, and the rigid and substantial nature and mounting of the former, malri-ngit possible to operate upon more fragile-materials, spin finer yarns, and build up considerably larger cops than has heretoforebeen practicable. It will be seen that the invention provides a ring mounting ofextremely simple and inexpensive character which may be incorporated in spinning or twisting frames of any usual or standard type Without substantial modification of the latter, and even readily applied to existing frames With negligible trouble and expense.

I claimi In a spinning or twisting frame or the like, in combination, a ring rail having an opening therein, a spindle extending through said opening, a spinning ring in said opening surrounding said spindle and having a unitary radially projecting ear extending from each of diametrically opposite parts thereof and engaging the faceof the rail, said ring being supported within said opening spaced from the edge thereof solely by said ears to provide a passage between said rail and ring substantially surrounding the latter, and means cooperating with said ears and rail for adjustably securing said ring within said opening.

In testimony whereof I affix my signature.

JOSEPH A. CLAPP.
