REVERSIBLE SPINDLE GUIDED PICKER FOR LOOMS Filed Aug. 16, 1955 22 3 0 Z8 3/ 3 I/ I i Z 4 F/G. 3

INVENTOR. 2'76; W/LL/AM LfflflUX Arrae/va s REVERSIBLE SPINDLE GUIDED PICKER FOR LOOMS William Ledoux, Lisbon Falls, Maine Application August 16, 1955, Serial No. 528,655 Claims. (Cl. 139-160) This invention relates to loom pickers and more particularly to loom pickers of the spindle guided type.

In the ordinary spindle guided picker, the picker is provided with an opening transversely therethrough to receive therein the upper end of a picker stick with the picker stick projecting through the aperture or opening. This opening tends to weaken the picker structure, and since the picker is subjected to heavy stresses and impact caused by the movement of the picker stick and loom shuttle, this type of picker is subject to splitting at the opening therethrough to receive the upper end of the picker stick. Several solutions have been proposed, including reinforcing means in the opening transversely through the picker to absorb the shock of the impact of the shuttle thereon as well as to minimize the force of the picker stick as it moves the shuttle along the spindle, or by an attachment which may be placed along the narrow face of the picker stick and inserted through the aperture in the picker to provide a wear plate. Even with the wear plates or other impact-receiving means, the picker is subject to splitting from the corners of the picker stick receiving opening through the body of the picker, rendering the picker inoperative for further use.

Therefore, it is the principal object of this invention to provide a simple, yet effective, picker construction which will prolong the life of the picker and which will avoid the possibility of splitting of the picker by eliminating the aperture transversely therethrough for the reception of the upper end of the picker stick.

It is a further object of this invention to provide a picker of the spindle guided type which is reversible so that an opposite end of the shuttle bunter portion of the picker can be used when the end first used becomes worn, thus adding to the life of the picker.

Still another object of this invention is to provide a picker assembly in which the picker may be quickly mounted in its proper relation without need for fine adjustment, and in which the picker can be quickly and easily reversed or replaced in the event that the shuttle bunter end in use has become worn or replacement of the picker is required.

Other objects and advantages will become apparent from a consideration of the following detailed description, forming the specification, and taken in conjunction with the accompanying drawings, in which:

Figure 1 is a perspective view of the picker assembly embodying this invention shown in connection with the usual picker spindle and picker stick;

Figure 2 is a cross-sectional view of the picker assembly taken substantially along line 22 of Figure 1, with the picker stick being omitted; and

Figure 3 is a cross-sectional view taken substantially along line 3-3 of Figure 2, and looking in the direction of the arrows.

With continued reference to the drawings, there is shown a picker assembly, generally indicated at 10, which assembly comprises a picker P provided with a longitudithe picker P in its nally extending bore 12 longitudinally therethrough which is slidably penetrated by a picker spindle 14 along which the picker P will be guided in a rectilinear path into contact with the shuttle, and a picker support or mounting, generally indicated at 16.

The kind of picker shown is used at both shuttle ends of fancy looms, but need not be limited to this particular type of picker or loom.

The picker P is of the usual pear-shape normally employed in connection with picker spindles including the double ended shuttle bunting portion 11. Except for the bore 12 longitudinally therethrough, internally threaded openings 35 transversely therethrough and guide bores 20, 22 and 21, 23, the body 18 is a solid piece of material of the type normally employed in the construction of this type of picker.

The picker P is provided with pairs of spaced

bores

20, 22 and 21, 23 opening through the lower and

upper faces

24 and 25. thereof, respectively, to receive in a selected pair of bores,

guide pins

26 and 28, respectively, upstandingly carried in spaced relation upon the upper surface of the support or mounting plate 30 of the picker support or mounting 16. This will insure proper placement and accurate location of the picker P upon the support or mounting plate 30 of the picker support or mounting 16. Also, the support or mounting plate 30 is provided with an upstanding guide flange 32 along one end thereof to form an abutment shoulder against which one end of the picker body 18 will contact to properly place the picker upon the support or mounting 16.

Means, in the form of bolts 34, pass upwardly through openings 31 the support or mounting plate 30 adjacent opposite ends thereof and threadingly received in suitably formed registering internally threaded openings opening through the lower and

upper faces

24 and 25 of the picker to secure the picker upon the upper surface of the support or mounting plate, in one position of the picker P.

The picker support or mounting 16 also includes a socket 36 integrally formed with the plate 30 and dependingly carried thereby. Thesocket 36 is provided with a picker stick receiving bore 38 opening through the lower end thereof to receive therein the upper end of a picker stick 40 whereby the proper movement can be imparted to guided path of movement slidably along the spindle 14. On wall 42 there are a plurality of openings 44 transversely therethrough and arranged in spaced relation in spaced transverse rows, as clearly shown in Figures 1 and 2, to lighten the overall weight of the picker assembly.

In the event one shuttle engaging end of the shuttle bunting portion 11 becomes worn from use, it is merely necessary to remove the bolts 34, then remove picker P and turn it over with the face 25 resting upon the mounting plate 30 so that the

guide pins

26 and 28 will be received in the

bores

21 and 23, respectively, to accurately position the picker P on the picker support 16 with the other end of the picker body 18 abutting the guide flange 32. This will place the opposite unworn end of the shuttle bunting portion 11 in position to engage the loom shuttle as it is moved along the spindle 14 and propel the shuttle across the loom through the warp shed. Bolts 34 are then inserted through openings 41 and threadingly received in the registering internally threaded. openings 35 in the ends thereof opening through the face 25 to secure the picker P upon the picker support. The picker assembly is then ready for further operation. Thus, it will be seen that the picker P is reversible.

From the foregoing, it will be apparent that there has been provided in a loom, a spindle guided picker assembly 10 which comprises a picker support or mounting 16,

a picker P secured upon the support or mounting for guided movement along a picker spindle, and means defined by the depending socket 36 carried by the support and adapted for attachment to means for moving the picker assembly along the spindle. This will provide a construction in which the picker P is of substantially solid construction to avoid tearing or splitting thereof during use to prolong its life as well as providing a quick and relatively simple manner of attachment of the picker assembly to the means whereby the assembly has movement imparted thereto to be moved in its guided path along the picker spindle.

While there is shown and described the preferred embodiment of the invention, it is to be understood that the structure is susceptible to change and modification Within the practicability of the invention and therefore should be limited only by the scope of the claims appended hereto.
