Number. 2,524'A3, for. overcoming this; and providing means. for adjustably mounting. a picker on a picker: stick... It is an: object: of this.- invention. to. provide an. improved. mean for. securely: fastening a. picker to; the upper' end. of the picker stick inadiustedz position and? wherebythe. picker can; be adj usted. imadifierentpositiona either: up or down.- a picker stick. minute: amounts: without; in any way. affecting the secure adjustment of the same; It: is. an. obj ect, of this. invention. therefore. to provide: in. the upper front. surface. of. the: picker stick' a vertically disposed. groove or: cavity. in. which. a. sleeve is fixedly secured, said; sleeve: be inggprovided withthreads or other suitable;pro-- jections' thereon. for. securing. the same in the cavity in the. picker. stick and the. internalporrtion. of; said. sleeve. also. being. provided with a plurality of; threads. Aportion of. the sleeve is: cut. away. so: that. it. isv flush with. the surface of. the picker stick to thus". permit a screw" to be. threadably mounted. in the, internally threaded portionof the sleeve so: that: the threadsof the screw will extend. beyond the. surfaceof the picker; through the. cut away portionsof the. sleeve and: will engage: the. adjacent. surface of: the picker tohold. the picker inxfixed relation to the picker stick, and; to thuspermit minute adjustment of. thewpicker; relative. to the picker stick by. adjustmentof. said screw;. Some of the objects. of the invention having; been? stated; other objectswill appear asthe description proceeds, when taken in connection withthe accompanying drawings, in which- Figure 1- is an elevation of a picker stick and showinga picker secured thereon by my improved means; Figure 2 is asectional plan View taken along the line 2--2- in Figure 1 5 claims; (01. 139-159) 2 Figure 3 is avertical sectional view;- taken along? the line 3--3' in Figuresz; Figure 4 is. a vertical sectional view when; along the line 44 in Figure 2; I Figure 5 is an exploded. isometric view" of. the upper end of the picker: stick; the guiding sleeve the picker, and the securing. screw before the: same are assembled; Figured is. a vertical sectional view similar. to Figure 3 but showing a; modified. means'for' se curing the sleeve in the picker'stiek. Referring more specifically to the. drawingszthe numeral l0 indicatesa. conventional picker sticlr;v the lower end of which is: adapted to; be. secured. in a conventional manner to a; shoe by means of a bolt fastened through a. hole: H7 in: the; lower end of the picker stick. On the. upper end of. a. picker stick there is. mounted a. conventional picker [2 formed of layers of cloth. impregnated with rubber vulcanized together or in any other suitable manner and being provided with a cavity l3 in the front face thereof for receivingjthe. nose of a shuttle. The picker l2 must'be': adjusted relative to thepicker stick in to'permit the nose of the shuttle. to coincidewith the-cavity I3; The picker has a vertically disposed opening: l4 therein for reception of the picker stick ID; Instead of securingthe-picker to the picker stickv by a woodscrew penetrating a hole in the back portion of the picker, the picker is secured to the picker stick in a manner similar to that shown in my co-pending application Serial Number 792,487, now Patent Number 2,524,443, means of a screw being positioned between. the' front face of the picker stick l0. and the proximate face of the picker l2. However in practiceit has sometimesbeen. difiicultto insert. a screw as described in my said co-pending, application; and therefore I have provided an improved guide. for said screw to facilitate insertion of thesame. and to provide a more effective securing means. To this end, the upper end of the. picker stick in the slot or cavity 16 by any'suitable means and in Figures 1 to 5 the sleeve IT is. shown as being provided with a pluralityofexternal threads I8 adapted to engage thesurface of the cavity Hi to fixedly secure the sleeve l1 therein. The sleeve I1 is cut away throughout its length a portion preferably equal to substantially one-' fourth its circumference so that the sleeveis; concavo-convex and the edges of thesleeve are positioned in the picker stick the fiat edges 20 of the sleeve I! will be flush with the front face of the picker l0. The sleeve I! is also provided with a plurality of internal threads 2| adapted to receive an externally threaded screw 22. It will thus be observed that when the sleeve I1 is positioned in the picker stick 10, the picker [2 may be positioned on the upper end of the picker stick l0 arid the screw 22 may be partially inserted in the upper end of the sleeve H, the threads of the screw 22 also engaging the proximate surfaces of the picker I2. The screw may then be tightened and the internal threads 2| of the sleeve I! will serve to guide the same and hold it securely in position as the screw 22 is tightened, the threads thereof will cut corresponding threads in the proximate surface of the picker i2 to thus hold the picker l2 securely in fixed relation tothe picker stick I0. When it is desired to adjust the picker [2 relative to the picker stick ID the screw 22 may be tightened or loosened as desired, to permit relative adjustment of the same. The vertically extending cavity H6 in the picker stick l0 preferably, extends at an angle, that is, it: is more shallow at its lower end than at its upper end, and the sleeve I? is cut away at at an angle so that the sleeve is wider at the top than at the bottom thus causing the screw 22 to cut relatively shallow threads in the picker 12 at the top thereof and to cut progres- Qsively deeper threads in the picker i2 as it is driven home thus effectively securing the picker li2'to the picker stick I0. If desired, instead of mutilating or marring the surface of the picker which fits against the front edge of the picker stick, the picker l2 may be molded with a suitable groove therein having female threads 25 for receiving the front portion of the screw 22, as provided in my said co-pending application. Referring to Figure 6, there will be observed a slightly modified form of the improved picker mounting and like parts bear like reference charthis cavity I6 is a sleeve H, the sleeve ll being provided with at least one and preferably a pinrality of projections 30 on the outer circumference thereof, said projections 38 thereon imbedded i the proximate surface of the picker stick If! to securely hold the sleeve I'l' within the cavity I6 of the picker stick Hi. The picker !2' is secured on the upper end of the picker stick [9 by means of a screw 22', substantially as heretofore described, the sleeve ll being provided with internal threads 2| adapted to receive the screw 22. v It is thus seen that there is provided improved means for securing a picker on the upper end of a picker stick by means of a screw being driven between the front surface of the picker stick and the proximate surface of the picker and said screw being guided and held securely in position by means of an internally threaded sleeve secured in a cavity in the front portion of said picker. In the drawings and specification there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being defined in the claims. I claim: 1. In combination, a picker stick for looms and a picker mounted on the upper end thereof, the front surface of the upper end of thepicker stick having a vertically extending groove therein, a concavo-convex sleeve secured in said vertically extending groove with its edges flush with the front portion of said picker stick, said sleeve being internally threaded, and an externally threaded screw adapted to fit within the sleeve so that a portion of said screw will extend beyond the front surface of said picker stick to engage and cut female threads in the proximate surface of the picker as the screw is driven home in the sleeve. 2. In combination, a picker stick for looms and a picker mounted on the upper end thereof, the front surface of the upper end of the picker stick having a vertically extending groove therein becoming shallower as it progresses downwardly, a tapered concave-convex sleeve secured in said vertically extending groove, and having its edges flush with the front portion of said picker stick, said sleeve being internally threaded, and an externally threaded screw adapted to fit within the sleeve so that a portion of said screw will extend beyond the front surface of said picker stick to engage and cut female threads in the proximate surface of the picker as the screw is driven home in the sleeve. 3.
