PICKER FOR TEXTILE MACHINERY Filed Feb. 18, 1938 INVENTOR HENRY IV- BHCON.

aw J ATTORNEYS guide channel at vide a flared bottom portion of Patented Mar. 7, 1939 UNITED STATES PATENT OFFICE Henry M. Bacon,

Dayton Rubber Mann ton, Ohio,

' application My invention relates to pickers for textile machinery.

It is the object of my invention to provide a picker having molded rounded edges surrounding the picker stick opening and to provide in connection therewith a flared or widened picker stick hole, a rounded or offset bottom and a molded angular shuttle point guide channel. 7

It is a further object of my invention to provide a picker of layers of fabric and rubber vulcanized together in such a manner that the ends of the fibers are sealed to exclude moisture and the smooth edges will prevent hanging filling.

It is a further object of my invention to prothe stick hole to make installation and fitting much faster, to eliminate turned under plies, to prevent picker. stick binding and to provide a denser portion which will cause slower wear and longer life.

It is a further object. of my invention to provide such a picker of oil and static proof material in order to increase the life of the picker and to eliminate the difficulties with static electricity inherent in the operation of mechanisms associated with textile machinery. It is a further object of my invention to provide a rounded or offset picker bottom that will act as a picker guide, being of particular value in connection with loose fitting sticks so that it will enablethe utilization of a lower location of a shuttle hole and will prevent tear-outs at the bottom of the picker.

It. is an object of my invention to provide a the bottom of the shuttle contact hole to reduce the tendency of the shuttle to side track to increase the normal picker life and to offset warped sticks.

Referring to the drawing; Figure 1 is a side elevation of the picker. Figure 2 is a top plan view thereof showing the flared or widened stick hole.

Figure 3 is a bottom plan view thereof.

Figure 4 is an end elevation of the picker from .the side of the guide for the shuttle point.

Figure 5 is a section on'the line 5-5 of Figure looking in the direction of the arrows.

Figure 6 is a section on the line 66-of Figure 1, looking in the direction of the arrows; 1

Figure '7 is a section on the linel-l of Figure 4, looking in the direction of the arrows.

Referring to the drawing in detail, the picker of this invention consists of a picker body I having a vertical'picker stick hole 2 therethrough which is flared from .top to bottom and has its Dayton, Ohio, assignor to The facturing Company, Daya corporation of Ohio February 18, 1938, Serial No. 191,286 -5 Claims. (Cl. 139-159 upper edges turned over or curved as at 3, l, 5 and 6. 1

It will be observed that the layers of fabric 1 impregnated with rubber 8 are compressed at these turned over or rounded edges so that the 5 fabric lies parallel to the rounded surface of these edges. The picker is provided-with rounded bottom edges 9.

One end of the picker is provided. with an ovoid recess l0 having a diagonally disposed cylindrical opening at the base thereof forming an angular guide passageway I l to guide the shuttle point.

It will be observed further that the layers of to this guide passageway and parallel to recess l0 so as 'to form a strong reinforcing shuttle guide. The layers of .fabric 1 are disposed at right angles thereto surrounding the opening 2 so that any friction on the walls of the opening will be 20 parallel to the surface of the fabric. The sameis true of recess l0.

The resilient material and fabric layers are molded and vulcanizedin a molded condition having rounded edges with the layers com- 25 pressed parallel thereto.

In the place of rubber, synthetic materials, such as derivatives of divinyl acetylene, butadiene, or one of the poly-sulfide resins may be employed. Any one of the synthetic rubbers are 30 useful because they are both oil resistant and because they have marked properties of being free from the accumulation of static electricity.

The fabric layers are molded so that they conform to the depression In and follow the contour 5 thereof as indicated. In this manner the wearing surface of the fabric is on the surface of the fabric and there is no wear across the ends of the fabric. This forms a dense section or area hend within my invention such modifications at 4:5

maybe necessary to adapt it to varying conditions and uses. Y, Having thus fully described my invention, what I claim as newand desire to secure by Letters Patent, isi

1. In combination, a picker body having a picker stick opening therethrough, one end of saidopening having rounded edges flaring out-. wardly, said picker having a recess shuttle guide on one face thereof with a guiding passageway 56 angularly disposed with respect to the base of said recess, the walls adjacent said guiding passageway being of dense reinforced construction.

2. In combination, a molded vulcanized picker comprising a picker body with a flared passageway therethrough having rounded marginal edges and an angularly disposed shuttle point guide projecting through and into one face of the exterior of said picker, said guide portion comprislng walls of denserconstruction than the interior of said picker body.

3. In combination, apicker body having a picker stick passageway therethrough with rounded edges at the mouth thereof, said picker being formed of a plurality of layers of fabric and resilient material with the layers of fabric compressed adjacent the worki'ngsurfaces and arranged in parallel to the rounded wearing surfaces thereon.

4. In a picker, a picker body formed of a plurality of U-shaped layers of fabric and resilient material and a plurality of generally transversely-arranged vertical layers-of fabric between the legs of said U-shaped layers of fabric, a portion of the layers of fabric being arranged to form a vertical opening the axis of which is parallel with said layers of fabric making up said U-shaped body; Dression arranged near the bottom central portion of said vertical opening, said layers of fabric adjacent said depression being arranged in parallel relationship with respect to the walls thereof and in closer engagement with one another than the rest of the fabric layers to form a-denser section to take the wear of the picker stick guide engaging said depression.

5. In a pickerizfcrmed of a plurality of layers of fabric and resiiient material and having a picker stick opening therethrough, a picker stick guide depression disposed centrally thereof, said layers of fabric being arranged in parallel relationship with respect to the wearing surfaces onsaid picker and in closer association one with the other adjacent the wearing surfaces of said picker to substantially increase the wear resistant properties of the picker.
