CHARLES T. ATHERTON, OF PROVIDENCE, RHODE* ISLAND, ASSIGNOR '.DO ATHERTON' SPINNING RING COMPANY, OF PROVIDENCE, RHODE ISLAND;A A- CORPORA'IION 0F- RI-IODE ISLAND;

SPINNING MIAGHINERY.

y To all whom it may concern:

Be it known that I, CHARLES T. ATHER- TON, a citizen of the United States, and a resident of Providence, inthe county of Providence and State `of' Rhode Island, have invented certain new and useful Improvements in Spinning Machinery, of which the following is a specification.

My invention, while relating primarily to spinning machinery, has reference more particularly to the spindles and spindle supports made use of therein, and especially to those forms of such. devices wherein the spindles are of the class which are known to the art as dead spindles, and receive whatever rotation there is imparted to them through the strain of the yarn in being spun and wound into cops, or upon bobbins carried by them. In U. S. Letters Patent No. 749,470, dated January 12th, 1904, is shown and described a spindle of this character. with an appropriate support therefor, in which the spindle is provided with a drag or devices by which its rotation when in operation may be frictioiially resisted and the amount of such resistance regulated and controlled to suit it to the requirements of the yarn being produced or wound. The construction shown and described in such Letters Patent, while efticient in operation when employed in the production and winding of yarns that are spun and wound in a dry state, is unprotected in its drag, or rotating resisting de` vices of the spindle, from the action of the water and other objectionable substances when the construction is employed in the spinning and winding of linen, jute or other materials that are spun and wound in a wet state, and such water or other substances enter it, with the result that the operative eHiciency of the parts is more or less impaired. Moreover, with this construction no provision is made for preventing the rotation of the friction resisting surface that cooperates with the spindle to retard its rotation, and, imder some conditions, this Isurface rotates with the spindle, causing thereby the part or parts upon which such surface is formed to wear unnecessarily.

My present invention is designed as an improvement upon this construction, and it has for its object the production of a spindle and the supports therefor, in which, among other things, not only is' the drag upon the Specification ofi Letters Patent.

Application iled August 1, 1907;

Serial No. 386,580.

spindle, or the parts employed to oppose the friction-al resistance toits rotation, inclosed andv protected from the water contained in tbe yarn being` spun and wound, as well as from the other objectionable substances that are present during those operations, but the part carrying the surface which coperates with the spindle to frictionally reta-rd its rotation, is held from rotary motion, and the lubrication off the spindle more eiiciently accomplished.

To these ends, the invention consists in certain peculiarities of construction and combination of' parts, all of which willA be` first described, and the distinguishing features of novelty then pointed out in the subjoined claims. l

Referring to the accompanying drawing, which forms a part of' this specification, Figure l, is a side elevation of a spindle and the support therefor constructed in accordance with one form of my invention, showing their relationship with respect to a ring-rail, a rotating ring, and a supporting spindle-rail, which are severally shown in section; Fig. 2, a side view of a spindle, the support therefor, and the other accessories, the spindle, the step, the spring detent for cooperating with the adjusting devices for the drag, and the pin for preventing the rotation of the bolster and step in their holder, being shown in side elevation, and the remaining parts in aXia-l section; Fig. 3, a transverse horizontal section, taken in the plane aa a? of Fig. 2, and looking downward, and Fig. 4, a like transverse horizontal section, taken in the plane y y of said Fig. 2, and similarly looking downward.

In all the figures, like letters of reference are employed to designate corresponding parts.

A indicates the spindle, and B the spindle rail upon which the spindle is supported. The spindle A is or may be of any ordinary ,or preferred construction, and, in practice,

it is employed in connection with appropriate yarn twisting and winding devices C,

and with a cooperating rail D. These twist-V ing and winding devices, with the coperating rail however, form no part of my present invention, but are illustrated in the drawing to more particularly show the relationship of the spindle with respect to them, and are or may be of any approved or well Fatented Apr. 5, 1910.. n

known character and require no further description herein. In the form of the invention which I have selected for purposes of illustration however, the spindle is shown as gradually tapered in opposite direction from its middle portion toward its upper and lower ends, with its upper end provided with a reduced cylindrical section a, and its lower end equipped with a conical step al.

For supporting the spindle A upon the spindle rail B, I make use of a holder E, which is preferably constructed with a cylindrical chamber or socket e, formed in and extending downward within the same to near its lower end, and also with a downwardly extending shank c1, which is adapted to enter and fit a suitable orifice Z), formed in the spindle rail B, in which it may be held either by a set screw b1, or by a nut b2 threaded upon its lower end, as preferred. IVith the holder constructed as thus explained, it receives the lower portion of the spindle A, which is rotatively mounted therein through the intervention of a bolster bearing F and step bearing H. To permit of this mounting of the spindle therein, the bolster bearing F is preferably constructed in tubular form, with enlarged upper and lower end portions f and f1, which are adapted to enter and closely fit the interior of the chamber or socket c, and also with an interior orifice f2, which extends longitudinally through it, and is of a form and size to loosely fit the spindle at or near both its middle and lower end portions; while the step bearing II is constructed in the form of a screw plug, which is threaded in the lower end of the bolster tube, and supports on its upper flat end the spindle A, which rests thereon, through its step al. By this construction and arrangement of parts, as will be seen, not only is the spindle supported upon the spindle rail and lateral bearings aiiorded to it at or near its middle and lower end, but such spindle sustained against the action of gravity, and rendered capable of vertical adjustment when required. The spindle A, being thus mounted, is free to rotate in and upon its bearings, as the exigencies of its use may require; and, in order to provide for the lubrication of its bearings, the chamber or socket c in the holder E is preferably constructed with a closed bottom, whereby, in addition to serving as a holder for the bolster and step bearings, it also serves as a well or receptacle to receive and hold the lubricant, while the peripheries of both the enlarged end portions f and 'l of the tube F are equipped with one or more longitudinal grooves f3, which is or are connected with the interior of the tube near its or their respective upper and lower ends by ducts f* and As thus constructed and equipped, the lubricant may be supplied to the chamber or socket c by depositing it in essere the upper end of the groove f, or in any one of them when a plurality is employed, and allowing it'to flow downward through the same into the socket, which may be filled to its top therewith if so desired. It is preferred however to supply it thereto from a reservoir e2, with which one or more of the grooves f3 may be connected by a duct c3, and to locate this reservoir c2 in the upper surface of an enlarged flange-like port-ion c4 formed at the upper end of the holder E, as shown.

In some instances the enlarged end portions 7 and f1 of the tube I" will fit the chamber or socket e sufiiciently tight to prevent the tube from rotating therein, and the relationship of the groove f3 with the duct c in that case will be maintained by friction alone. Then however it is preferred to insure of this result being accomplished in a more positive manner, a locking piu c may be employed, which, when used, extends inward from the walls of the chamber or socket c and engages at its inner end with any convenient depression formed in the tube F, as, for instance, with one of the grooves f3, or otherwise.

While the mounting of the spindle, and lubrication of its bearings are thus elteeted, the rotation of the spindle is resisted and a drag imposed upon it by cooperating disks I and I1, of which the former is rotatable and the latter stationary. The disk I, in the embodiment of the invention shown in the drawing', is preferably constructed on the lower end of a hub or collar fz', and is fixedly secured upon the spindle, whereby to rotate with, and be held in a fixed relationship to, it, while the upper end of the hub or collar is or may be provided withdogs z'l for engagement with the bobbin or spool when one is employed. The disk Il, on the other hand, is constructed with a downwardly extending annular sleeve 2 upon its back, with the interior of this sleeve provided with a screw thread for engagement with a corresponding screw thread t* formed on the exterior of the enlarged Hange-like portion e4 of the holder E, whereby to provide means for the adjustment of the disk I1 toward and away from the disk I, to increase or decrease the resistance or drag opposed to the rotation of the spindle, as the exigencies of its rotation may require. With the parts thus employed the resistance of the drag opposed to the rotation of the spindle will be increased by simply rotating the disk I1 in the proper direction on the flange-like portion c* to cause it to be forced against the disk I with greater pressure; while its decrease, on the contrary, will be accomplished by reducing the pressure with which the disk Il is forced against the disk I, by rotating the former disk on the flange-like portion c4 in the opposite extending direction. rl`hus, as will be seen, bythe means described the resistance to the rotation of the spindle, or the drag thereon, may be regulated and controlled, by simply r0- tating the disk I1 Von the flange-like portion et in the required direction; and in order to retain the disk in any-ofI the positions to which it may be thus rotated and adjusted, a spring detent L is employed, which, secured to the holder E by suitable screws Z, is adapted to engage at its free end with appropriate notches formed in the periphery of the disk, as shown.

In some instances the disk I1 may contact directly with the disk I, without the employment of an intermediate medium between them. I prefer however to interpose between them one or more layers of felt or other frictional material M made in the shape of a washer, or washers, as thereby more eiiicient results are accomplished; and, with a view to preventing any rotation of these layers, or any of them, I make use of an abutment m, which, in the form of the invention shown in the drawing, is constructed in the shape of a tube, and extends downward through the disk I1, outside the periphery of the disk I, with its upper end upward through an orifice formed in the layer or layers of felt to some distance, and with its lower end projecting downward below the under surface of the disk, in proper relationship to the reservoir e2, whereby, in addition to serving as a means to prevent the rotation of the layer or layers of felt, itmay also serve as a means through which the lubricant may be supplied to such reservoir.

For excluding water and other' objectionable substances from the layer or layers of felt and from the bearings of the spindle, the upper surface of the disk I1 is provided near its outer edge with an upwardly extending annular sleeve-like fiange 7, and, in connection therewith, is employed a cover N, which is constructed with an orifice n through its center of a size to receive and fit the spindle, or the hub or collar z', when one is employed, and also with a downwardly extending annular flange nl around its outer edge, which, provided in its interior with a screw thread a2, engages with a corresponding screw thread S formed on the outer surface of the upwardly extending flange 7. As thus constructed and arranged, not only is a chamber formed upon the disk I1 for the reception of the layer or layers ofl felt, but a cover therefor as well; and in order to allow for the lubricant being supplied to the reservoir c2 when required, the cover N is or may be provided at a point over the tubular abutment m wit-h an orifice n3, which, when the lubricant is not being supplied, may be closed by an appropriate screw or plug at.

In most instances the cover N will exclude all water or other objectionable substances from the felt and bearings, but in order to more thoroughly prevent it from working downward around the hub or collar z', I find it convenient to employ a disk O, which is fitted upon the hub or collar near its upper end, and extends outward over the cover to such a distance as to deflect all water and other objectionable substances falling upon it outward away from the hub or collar, and prevent them from entering the space in the cap around it.

lVith the parts constructed and arranged as above explained, a spindle, with means for supporting it in operative position when in use, is provided, which, in addition to answering the various objects before pointed out, possesses other and further advantages in points of construction and operation, not necessary to mention herein.

While, in the foregoing I have described the best means contemplated by me for carrying my invention into practice, I wish it distinctly understood that I do not limit myself strictly thereto, as it is obvious that the same may be modified in various ways without departing from the spirit of the invention.
