LUBRICATING DEVICE FOR PICKER SPINDLES.
Application led February This invention relates to improvements in lubricating devices for picker spindles of looms and it is the general object of the invention to provide such a device which will be dependent for its operation upon some part of the picking apparatus of the loom and may have a lubricating element which can slide along the picker spindle to deposit a iilm of lubricant.
The shuttles of looms are carried by lays which swing back and forth in the loom frame and-as the lay moves backwardly the picker stick will act to propel the shuttle when the lay is approximately half way between its front and back positions. In certain classes of looms the motion of the picker stick is communicated to the shuttle by means of a so-called picker which slides along a rod or picker spindle to be guided by the latter. kIt is found that in fast running looms considerable difficulty is found in properly lubricating the spindles and it is an important object of my present invention to deposit a lm of oil or other suitable lubricant on the top and bottom of the spindle as well as the side thereof.
It is a more particular object of my present invention to provide a lubricant carrier which shall be pivotally mounted on a picker 3o stick actuated arm and having a portion to engage the spindle which is offset from the l axis around which the carrier moves.
With these and other objects in view which will appear as the description proceeds, my
invention resides in the combination and arrangement of parts hereinafter described and set forth in the claims. l
In the accompanying drawings, wherein I have shown a convenient embodiment of my invention,
Fig. 1 is a fragmentary top plan view of one end of a loom having my invention applied thereto and showing the lay in its rearmost position with the lubricating element in Contact with the spindle,
Fig. 2 is a rear elevation taken in the direction of arrow 2, Fig. 1, n
Fig. 3 is a view similar to Fig. 1 with certain parts removed and showing the picker stick in shuttle propelling position with the lubricating device at rest,
Fig. 4 is an enlarged vertical section on line 4-4 of Fig. 2, and
7, 1928 Serial No. 252,615.
Fig. 5 is a detail horizontal section on line 5-5 of Fig. 4. I have indicated a loom 10 and a lay L havmg a shuttle box B in which may be located the shuttle S. The shuttle box has a back wall 11 against which the shuttle is held by binder 12 and there are projecting rearwardlyffrom the shuttle box 'inner and outer lugs 13 and 14, respectively, which aord support for a picker spindle 15. Adjacent the inner end of said spindle there is` located a conical bushing 16 which is seated in lug 13, said conical bushing receiving the tapered inner' end of the spindle 15. The outer end of the spindle shown at the left of F ig. 1 extends through a bore 17 located in the lug 14 and is held in position against endwise movement by a screw 18. A picker 19 has a shuttle engaging portion 2() and extends through the wall 11 as shown in Fig. 1. Said picker is also provided with a bore 21 which receives the spindle 15 and that portion of the picker which lies between the bore and the shuttle is provided with a slot 22 through which projects the upper end of the picker stick 23. The particular method of mounting the picker spindle 15 forms no part of my present invention and may be substantially the same as that shown in patent to Lanciault No. 1,594,620.
A stand 24 is secured to the loomside by a bolt 25 and extends to the left as shown in Figs. 1, 2 and 3 to afford support for a vertically extending stud 26 which is adjustable in a slot 26a in the stand and is held in posit-ion by a nut 27. An actuating lever 28 is pivoted on the stud and has at the left hand end thereof a head 29 which may be covered with a strip of shock absorbing material such as leather, indicated at 3G. The head may be provided with an incline 31 adapted for engagement by the picker stick 2.3 should the head lie in the path of the picker stick as the latter returns to inactive position after a shuttle propelling movement. The st-and 24 and parts supported thereby which have been described may be substantially the same as set forth in co-pending application filed by Turner, Ser. No. 252,616, filed Feb. 27, 1928.
My present improvements relate more particularly to the form of lubricating element which has contact with the picker spindle 15 and in carrying my invention into effect I exthe right to propel the shuttle.
tend the lever 28 to the right of: the stud to form an arm 40. A stop pin al on the stand 24E limits movement of the lever under action of a torsion spring 4Q one end 48 of which lies behind the lever 28 while the other end ifi extends behind a part et the xed stand 2a.
ls shown in Figs. l and 3 the action of this spring isto hold the head 29 in 'forward position and with the arm 4:0 against the pin fit1.
A stud is supported by and extends upwardly from the right hand end of the arm t() and has pivotally mounted thereon a carrier element 5l having a finger 52 which is held against a stop pin 58 supported by the arm a0 by means ot a coil spring 54. @ne endet said spring lies behind the carrier element as at while the other end lies behind the arm 40 as at 56, and sai-d spring` coiled aroundlthe airis of the stud 50 to hold the element 5l yieldingly relatively to the arm 40 in theposition shown in Fi 3.
The particular form of the element 5l which I employ herein is set forth in Figs.
fl and 5, where it will be seen that said element lisprovided with an oil reservoir 57 in which is located a wick 58. A pin 59 extending between the vertical walls 60 of the reservoir holds the U-shaped portion of the wick asset Vi'orth in 4l, said wick being bent as at 6l and being held in this position by the pin 62. The reservoir is provided with a supply ot oilwhich is raised by the wick so that the lishaped portion lying opposite the pin 59 will bekept constantly saturated. with oil.
As shown in Figs. l and 3 that portion of the element 51 which is adapted tor cooperation withthe spindle 15 is offset from the stud j50 with respect to the length of the spindle. This 'construction is of importance in the operation of the device in that it causes the *wick-S-to 4slide along the spindle and thereby deposit a lilm of oil of greater length than 'the length `of the vwick which is in contact `with the spindle at rany one time.
'ln operation the lay L moves back and y'foi/thin the loom and the picker stick will be moved rom'the position shown in Fig. 2 to In a single `boxloom as shown herein the picker stick will be moved every alternate heat of the lay, being in the position shown in Fig. l on alter- 'natebeats and being` in the position'shown in Fig' on intermediate beats when the lay is in its extreme rearward position. l do not 'wish to be limited to this particular form of loom as the successful operation of my invenftion is not dependent upon the number of boxes inthe lay. As the lay moves rearwardlyon the'beat that the picker stick 23 is'non- .active the picker stick will engage the head 29 tofrock the lever 28 in a counter-clockwise direct-ion'as viewed in Fig. 1 around the stud l26. Theeii'ect ot' this movement is to project the element -51 forwardly until the wick en- *gagesthespindle as shown in Fig. 'llfandin Vmoves forwardly the lubricating` element `will have a second longitudinal movement along the spindle to return to its normal position with respect to the arm 40, after which con-` tinued Iadvancing movement of 2the -will carry `the 'picker stick awa-y from the head 29 andthe pai-ts vwill vbe restored-to the :position shown in T3 by torsion .spring` a2.
"0n the -neXt -beatof the loom ther-picker stick will ibe :operati-ve to propel the shuttle and when the lay-'arrivesfat its -rearmost :position fthe picker stick'will rbeimoved inwardly or to the right to assume the positionshown in Fig. 3. Under l"these 'conditions' the ilubrieating element will remain :at frest vwith the reservoir and wick l out of #the path fot movement-oit' tliepicker. `Iiilthis `way thefdevice is called into 1operation levery alternate beat of the loom, but-as previously stated al dolnot wish-to lee-limited to 'this particularrarrangement and-operation.
From the ii'ioregoing itwill be seen that El have Vprovided a. lubricating-device ttor`r loom picker spindles whereinaimovab-l-e reservoir is caused to have 'a side slipping `movement along one --side=and theftop'and bottom of a portien of 'the spindle, said movement being 100 in one direction asther-'lay approacheslthed-evicef and'being in the opposite direction-to r`return to normal as the lay movesaway from the dev-ice. Furthermore,'becauseof the side slippingaction of the reseiwoir,closeadjiist- 105 ments in the setting fof the parts iis 1 not :necessary. i
Havingfthus describedfinylinvention. it twill be apparent that changes :and modifications mayV be made therein by= those-skilled in the 110 art without departing ffromfthe spirit and scope otlthe invention l and :I do :not fwish to be limitedto the detai-lshere'infdisolosed,fbut what I claim is:
1. lna:l-ubricatingfdeviceifor a loom-liav- 115 `ing a layfmovable back andfortli inf-thelooin and having a picker stick and a picker spindle, aI device Kmovableabout -a lined pivot to l dle, a. memberiinovab-leby the picker stick as the lay moves, and a lubricating-:elementpivotally connected to the member and having an oset spindle engaging portion, Contact between the member and the picker stick moving the lubricating element first against the spindle and then along the same by a sliding movement.
3. In a. lubricating device for a loom having a lay movable back and forth in the loom and having a picker stick and a picker spindle, a lubricating member for the spindle movable by'the picker stick as the lay moves first in contact with the spindle and then along the spindle by a sliding movement.
