PICKER SPINDLE MOUNTING FOR LOOMS Filed Aug. 31, 1932 ZZMM Patented Nov. 28, 1933 v 1,937,435 PIQKER, SPINDLE MOUNTING FOR LooM's Albert Palmer, Worcester, Mass., assignor t- Crompton & Knowles Loom Works, Worcester, Mass., a corporation of Massachusetts Application August'31, 1932. Serial No. 631,23 9d' Claims.
The invention relates to a picker rod spindle for looms and it is the general object of the invention to provide a simplestructure for holding the spindle in position with respect to the lay and 5 prevent it from becoming loose during loom operation.
Certain forms of picking motions employ a slidepi'cker having a part to push against the shuttle and having another part usually beside the shuttle to slide along the picked spindle. Due to vibration and the shock incident to boxing of the shuttle, mountings previously employed for.
the picker spindle have not. been entirely satisfactory, showing a tendency to work loose and 15.. thereby interfere with the proper guiding of the picker end and the shuttle. It is an important object of myfpresent invention to provide a'picker spindle which is pivoted to the lay at its inner end and passes through a taperedthreaded plug at its outer end, the plug being secured to a part of the lay structure.
It is a further object of my invention to employ the general form of picker already mentioned in connection with a locking means which will prevent the plug from rotating with respect to the spindle. This feature, together with the fact that the pivot for the inner end of the spindle is fixed with respect to the lay, will hold the spindle and its plug definitely in position in such a way that the plug cannot lose its proper setting.
With these and other objects in view whichwill appear as the description proceeds, my invention resides in the combination and arrangement of parts hereinafter described and set forth in the claims. p
In the accompanying drawing, wherein a convenient embodiment of my invention is set forth,
Fig. 1 is a top plan view of a lay end showing a picker spindle made and mounted according to my present invention,
Fig. 2 is a rear elevation of the structure shown in Fig. 1, 1
Fig. 3 is an enlarged vertical section on line 3--3 of Fig. 1, parts being omitted,
Fig. 4 is a detailed end elevation taken .in the direction of arrow 4, Fig. 2,
Fig. 5 is a detailed horizontal section on line 55 of Fig. 3,
I Fig. 6 is a rear elevation of the plug, and
Fig. 7 is an end elevation on an enlarged scale looking in the direction of arrow 7, Fig. 6.
Referring to the drawing, I have shown a lay 10 having a lay end 11 provided withasubstantial 1y flat vertical surface 12 substantiallyperpendicular to the line of travel of the shuttle. A support 13 is secured to this surface by means of bolts 1% .and may havea notch or pocket15 to receive the 5 forward edge of the surface 12. Anouter guide plate 16 secured by bolts l'l'tothesupport 14 has a vertical guide groove 18 which receivestongue 19' of a gang of. shifting boxes 20. A second, tongue 21-at theinner end'of'the boxes slides in. a second vertical groove 22 provid'ed with strucl ture secured to thelay end. The shuttlesand' the binders, may be of usual construction and are 1.65 shifted by any .convenient'form ofjbox motion. I
The picker Pmay be of usual construction and is actuated by a picker stick 23 to propel the shuttle.{
My, invention relates more particular'ly tothe guide or .spindle for the picker, and. in carrying my invention into fefiect I employ that form of a spindle which has the inner end provided with an eye whichlies betwen ears 31rigidwith the lay end. A pivot'pin'32 extends through the ears of the eye so that the inner end of the spindle will not be cramped should the lay end swing slightly with respect to the lay as the latter beats up. V The outerend of the spindle is substantially cylindrical and passes through-a plug 33 having a clear bore 34 of substantially the same internal diameter as; the diameter of the'spindleu The plug is made more particularly as set,,forth in Figs. 6 and '7 and comprises a tapered threaded part or shank 35 which is received by'a corre-- spondinglyjtapered threaded bore 36 in the support 13. The plug is provided with a head 37 adapted for turningby means of a wrench or i the like and there may be located between the head and the threaded'part a'weakening groove or depression 38 which liesb'elow the adjacent threads for the purpose of'making the several threaded parts more resilient. Q
Two slots 40 are cut at right angles to each other through the threaded part or shank to provide four resilientprongs 39. A set screw 41 ex-' tends through the head to communicate with the bore so that it may look the plug to the'spindle' of the set screw. r
In use, the outer cylindricalend of the spindle is passed through the threaded bore'36 and then the eye is placed between the ears and the pivot and acheck nut e2 may be used to hold the same bolt 32 applied, as will be evident from an in 2L 7 dle, said prongs being resilient and being' wedged inwardly against the spindle by the tapered threaded bore 36. The set screw 41 is then inserted through the head of the plug and is set up tightly against thespindle, after which the'check nut 42 is turned to hold the setting of the screw.
By reason of the iconstruction set forth herein."
the spindle 'is' very 'efiectively clamped against a lateral vibration. The inner end is heldiby the ears and pivot pin so that rotation about the spindle axis is impossible, and the set screw 41 by passing through the plug;,holds -therlatter:
against relative movement with respect to the spindle. The ears and pivot pin therefo're serve to prevent the threaded part-of 'th'e plug-irom== rotating in the threaded bore 36 and 'thus-"ef- 'fectively retain the originat-setiring ofsitherplugz:w
Having thus described my invention it will be seen'that changes and modifications may be made therein by, those skilled in the art without dea. par-ting from the spirit'fland scope of the inventi'in and'I do not wishto' be limited to the dew tails herein di'sclosedbut what I claimiszi pere'dthre'aded bore to *5 receive the tapered V threadedplug; said plug having resilient portions 7 to be clamped 'against'the spindle as the'plug is" t A moved toward'the small end'of the tapered bore,
and means-to 'lock'theplug to the'spin'dle.
