VJILLIAM M. VTATTIE, OF ORCESTER, MASSACHUSETTS, ASSIGNOR TO CROMPTON & KNOWLES LOOM WORKS, OF VOROESTER, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.
DRIVE FOR LOOM PATTERN MECANISM.
Application led April 7', 1926. Serial No. 100,403.
This invention relates to a driving connection between one of the constantly moving shafts of a loom and a pattern mechanisin of the type set forth in patent to Knowles No. 134,932, and it is the`general object of the invention to improve upon the means heretofore employed for holding one of the bevel gears on the upright-shaft of such a loom in proper position.
The so-called Knowles head employs -a pair of spaced oppositely moving mutilated gear cylinders between which lie a plurality of thin vibrator gears mounted on vibrator levers which are controlled as to-vertical position by a pattern chain so as to move the'gears into operative relationship vwith respect to one or the other ofthe cylinders.
The latter are driven by bevel gears secured to an upright shaft the lower end of which is supportedv in a step bearing and has keyed thereto a guide collar through which eX- tends a driving pin secured to a vertically moving clutch. rIhe pin is received by a bevel gear which heretofore has been held-A in raised position by vmeans of. a collar held against downward movement on the upright shaft by upsetting a. portion of the latter immediately above the step bearing. VIVith this construction it has been found inconvenient to remove the bevel gear on the shaft when the same becomes broken or wornand it is a more particular object of my invention to thread a portion of the shaft and mount thereon a threaded collar a portion of which is split to yprovide a clamp by means of which the collar can be held in adjusted position on the threaded portion of the shaft. The bevel gear is provided with a recess in the'lower face thereof which rreceives the split collar, the latter acting as a support for said gear to hold the same in proper relation with respect to the collar keyed to the shaft.
lith these and other objects in view which will appear as the vdescription proceeds, my invention resides in the combination and arrangement of parts hereinafter described and set forth in the claim.
In the accompanying drawings wherein I have shown a convenient embodiment of my invention,
Fig. 1 is a front elevation of the end porfor the Knowles head equipped with my invention,
F ig. 2 is an enlarged vertical section through the lower end of the upright shaft and step bearing therefor, being in effect an enlargement of the part shown in cross section in Fig. 1, y
Fig. 8 is a detail horizontal section on linee-3 of Fig. 2, and
Fig. 4 is an enlarged vertical section on line 4-4 of Fig. 3. e
Referring more particularly to the draw! ings it will be seen that I have provided a loomy side having arches 11, one of which is shown in the drawings, and a head frame 12. Mount-ed for rotation in opposite directions in said head frame are upper and lower mutilated cylinder gears 13 and 1&1-, respectively, having shafts 15 and 16, respectively. Keyed to said shafts are bevel driving gears 17 which mesh with and are driven by corresponding bevelv gears 18 secured to the upper end of theupright shaft 19. -The latter shaft extends through' a bearing 2O secured'to the head frame and rotates constantly during the runningA of the loon.
A heel pin 21 mounted on the head frame supports the outer end of a plurality of vibrator levers one of which 1s Vindicated at 22, each lever having mounted thereon a v1- ybrator gear 23 which is located between the upper and lower cylinders. Pivotally at tached as at 24 to each gear 28 is a connector 25 the inner endof which has operative engagement as at'26 with a harness lever 27 moving about Va center 28 fixed in the arches `of the loom. v A pattern mecha.
nism indicated at 29 controls the vertical position' of the vibrator levers 22 to determine which of the `mutilated cylii'lders will actuate the vibrator gears 23.
' In order to drive. the upright shaft 19- I may connect the same with the bottoni shaft 30 passing through a bearing 31 secured to the loom frame and having keyed to the outer end thereof a bevel gear 32. The latter gear meshes with a corresponding bev-el gear v33 mounted loosely on the bottom of the shaft 19 and adapted to receive the lower end of a driving pin 34 which is riveted in a clutch 35 and passes through a collar 36 keyed to the shaft 19.' By means of lever 37 the clutch `35 and driving pin may be lifted so as to permit free rotation of gear independently of upright shaft 19. rEhe bearingl'is provided with a step 88 shown more particularly in Fia. 2 which receives thereduced lower end 59 of the upright shaft. rlhe mattei'tlius far described is of common'construction and'forins'no part of my present invention.
In carrying out my improvements l pro- Avide the lower end of the shaft 19 with threads 40 located immediately above the reduced end 39, said threadsextending upwardly from a shoulder All on an intermediate section t2 Vof the shaft located between that part of shaft 19 on which the clutch slides and the reduced end 39. The threaded portion extends somewhat above the bottom of the recess i3 formed in the lower part of bevel gear 33 and has threaded thereon a collar 44 shown more particularly in Figs. 2) 3, and 4. Said collar is threaded internally as shown at t5 in Fig. 3 and is split or slotted as at 46, the slotted part extending slightly beyond the center lino ofthe collar as indicated vin Extending; across theslotfpreferably centrally of the slottedportion., is a screw t7 pas. ,g freely throughl the lower part and threaded into 'the upper part of the slotted por -ion' of the collar 44:. The collar is made of material at least slightly resilient so'th'at as the screw is tightened inplace the two parts separated by the slots 46 are drawn together on the threads l0 to serve as a clamp to 'prevent creepingv or angular motion of the collar relative to the upright shaft 19. The split collar may have holes48 extending therethrough for cooperation with a Spanner wrench not show-n. Y
Under normal operation the bottom vshaft 30 rotates constantly and when the parts are in the position indicated the drawn will transmit rotary motion to sha-ft "i9 throughbevel gear 33 pin 34, and collar 36. thereby driving the head motion located adjacent the upper end of the shaft 19'.
lVhen it is desired toremove any portion of the construction located at tno bottom of rthe shaft 19 such as the 'clutch .lreycdto the-collar 8,6 or 2gear 33p the bearimz` 3l is let down to permit access to the cod l. after which thel screw 4G is slaclrened ni l the split portionsof the collar 3e aesrune their normal non-clampingposition; 'The split collar may then be removed by means of a spanner wrench as previously described. The defective parts may then be removed and replaced by others after which the collar may be replaced and the scr-ew 47 tightened, care being` taken to establish proper' spacing` between thelcollar 36 and tbegear 33 so as to permit free movement of the same when the head is disconnected byflever 37 butto prevent undue play between the gearsy 32 and From the foregoingit will be Seen that I have provided a very simple device for supporting the bevel gear located at the bottom of the uprightshaft of the well-known Knowles loom and that the collar hereinbefore described can be removed and replaced repeatedly without dislipgurement of anyvportion of the upright shaft 19 and that by means of the vertical adjustment of the collar lll I. am enabled to establish a better adjustment between the gear and the keyed collar 86 than has been possible heretofore. y
Having thus described my invention, it will be apparent that changes and modilications may be made therein by those skilled in the art without depfartingfrom the spirit and scope of the invention, and .I do not wish to be limited to the details herein om closed, but what Icflaim is: 'i
ln driving means for pattern mechanism for Ilooms including a pair of oppositely constantly rotating` spaced actuating cylinders to cooperate with vibrator gears.
mounted Yon vibrator levers controlled by pattern mechanism', said loom also includingl a driving shaft having; a bevel pinion se-y cured theretoY and bevelpinions for said actuating` cylinders` in combination, Van `np-r rirht shaft interposed between the driving shaft of the loom and said. cylinders having' bevel 'pinions Vsecured thereto. to mesh 1with the bevel pinions of said cylinders, a bevel pinion on thelower end of the upriaht to mesh with the p in'ionfon the l ivingshaft threads cut .on a reducedpart c .he upright-Y shaft at the lower end thereof, an internally threadedv s1appertingj` collar len said*l lower portion of theupright shaftto support the bevel p1 ionfon the lower end of aidshafty and means to su-piort said. upright shatt.
