PICKER CHECK FOR LOOMS Filed Jan. 31, 1944 ,in the box looms.

Patented Dec. 12, 1944 UNITED STATES PATENT F Fl-I'C'E PICKER CHECK FORLOOMS Horace M. "Phillips, GastoniafiMC. Application January .31, 1944, Serial No. 520,451

'7 Claims. (01.13'9-167) This invention relates to a picker mheck tor looms, and more especially to spring .means I-ior arresting the picker stick, .as ritiis moving outwardly with relation to one edge of the cloth being woven under impact loif an incoming shuttle into the shuttle Lbox. a

Herotofore the conventional meansfor arresting movement 01 the picker stick hassbeen :by

means of a check strap which is secured to :a bracket onone side of the lay aofthe loom below the-shuttle box, and has its other side portion frictionally engagedby suitable fingers for applying the desired amount 0f resistance to movement of the check strap to thereby arrest the picker stick. Check straps are usually 'made (of leather, and are therefore very expensive and soon become worn, requiring replacement.

It is an objector this-invention to provide a picker stick check comprising a member adapted to be secured to the -'conventionalwbracket which heretofore has secured the overlapped ends of the conventional check strap in position, said member having means for adjusting the same relative to the bracket and also for adjusting the same relative "to :the lay of the doom, and having on one end thereof an adjustable angle member to which is secured :an adjustable leaf spring so *that the angularity of the leaf spring relative to the member can be adjusted both laterally of the shuttle box and longitudinally of the same.

It is another object for this invention :to provide a spring means for arresting the outward movement of a picker stick, said spring means employing the conventional spring which is in common use in many mills in box looms iorapply ing the proper amount of pressure-to the binders By providing an arresting mechanism "employing such a spring, the mills usually have these springs in stock so that if a spring used as *a picker check should become broken, it can be replaced within a very few minutes and operation "of the loom can be resumed.

It is a further objectoi this invention to provide in a loom, a strap iron member adapted to be ad'j'ustably secured to the-conventional bracket projecting downwardly from the'lower portion or the lay of the loom and said strap iron member having adjus'tably secured thereon a right angle bracket spring holding means and a leaf spring 'adjustalbly secured 'on the right angle bracket for engaging the picker 's'tiokinoutward travel under impact of the shuttle moving into the shuttle 'b ox, together with "means for engaging the'lower portion of the lay .for assisting in stabilizing and supporting the strap iron member which is secure-d to rthe conventional downwardly projecting braoket'thelay of the loom.

some :of the objects of the invention having been stated, other objects 'will appear as the description proceeds, when-taken in connection with the accompanying drawing, in which:--

Figure .l :is a side elevation .of the router portion of a shuttle box on the lay of the loom, and showing the picker stick engaging the leaf spring for arresting the same;

FigureiZ is a vertical sectional view taken-along the'l-ine 72-12 in Figure .1;

Figure 3 is aview of the right-hand lower portion of Figure 11 flocking from the opposite direction from the direction of view in Iligure 1.

Refer-ring more specifically to the drawing, the numeral l-l] indicates the ,lay of a loom haVing a suita'ble'b'inder l l which is -usually pivoted as at Ma and which serves to :box :and apply 'friction to a shuttle 12, the nose of which usually engages the picker 13, disposed on a "picker stick [4 which is pivoted as atits .lower end in a conventional "manner not shown. The outer end of the shuttleaboxzor the lay usually has a leather strap member it against which the picker stick sometimes strikes a't extreme limit of motion. The lay has a suitable .slot all in which the picker stick 14 has movement. The lay also has secured thereon :a conventional bracket 18 by any suitable ,means .such as bolts 19, and this bracket 'haslheretoforecbeenlemployed .for securing the overlapping ends :of a conventional check strap.

To the downwardly projecting leg of bracket =lB I-securesanaelongatedstraight strapironmember whichhas .an elongated slot 26 therein penetrated by a bolt 2:1 which alsopenetratesthe downwardly projecting :leg of bracket 1-8 to secure the strap iron :member '25 .in'position. This strap iron member has also :a-bolt 30 penetrating the same over 'w hi'ch the lower :forked :portion :of .a bracket 31 is adiustably secured, :the upper end of the bracket having an inturnediiorizcntahportion 32 adapted to 'ifit against the lower surfaces of the lay H] for assisting -2b1olt 221 :in supporting the strap iron :mem ber 2.5 'in "the desired position.

Near the extreme right-lend of the strap iron member '25 as s'hownin Figure 1, there is a vertically disposed slot '35 in which a bolt 36 is disposed, said b olt 36 also being disposed in a vertically disposed elongated slot 31 in a right "angle member 238 which right :angle member :38 is also secured to the strap iron member byimeans of a bolt 39 penetrating both the member 38 and the strap iron member 25. This slotted arrangement permits angular adjustment of the member 38 relative to the member 25. The member 38 has a portion 40 disposed at right angles to that portion which lies flush against one side of the strap iron member 25, and this portion 40 has transverse or horizontally disposed slots M and 42 in which

bolts

43 and 44 are disposed, which bolts also penetrate the shank portion 45a of a leaf spring 45 and the slots 4| and 42 allow for angular adjustment and angular position transversely of the lay of the loom of the spring 45. This spring 45 projects downwardly and inwardly to where its lower end is disposed in the path of the picker stick l4, and when an incoming shuttle is driving the picker stick outwardly in the shuttle box, the picker will engage the lower end of the leaf spring 45 which will gradually arrest the same and thus this arrangement entirely replaces the conventional check strap for looms.

In Figure l, the picker "stick in its outward travel has already engaged the lower end of the Spring 45, and has flexed it to a certain degree, but the picker stick has not as yet quite reached the limits of its outer travel. It is, of course, evident when the picker stick is projected to the other end of the shuttle box that inexpelling the shuttle from the shuttle box that the lower end 45b of the spring 45 will flex further to the left in Figure 1 and be ready to receive and engage the picker stick asit again travels outwardly in the shuttle box upon receipt of an impact from an incoming shuttle into the shuttle box.

The type of spring 45 which is shown is of the type used in box looms as a binder spring and as such, it has a concavo-convex shank portion 45a and a straight leaf portion 45b on its lower portion, the shank portion 45a giving rigidity to that portion which is penetrated by the bolts, and the portion 45b flexes under the impact of the picker stick as it is thrown against the lower end of the end portion 45b of the spring.

It is evident that due to the separability between part and part 38 and the removability of member 31 that this mechanism can easily be adapted for either side of the loom or for either end of the loom as the member 3| can be removed from bolt and turned 180, or reversed as to its side, and the member 38 can be taken off and inverted together with its spring and placed again on the strap ironl member 25. Also the spring being removable, it can be turned to a 180 position from the position shown in Figure 1 should it be desired to attach this mechanism to the other side of the lay or to the other end of the loom. Thus, I have provided apicker stick arresting apparatus which can be placed on either side of the lay of the loom or at either end of the lay without the necessity of having a special type of mechanism for each end of the lay, or for either side of the lay, and thus the mechanism is easily adaptable to all types of looms and for either end of aloom.

In the drawing 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.
