Application October 19, 1936, Serial No. 106,456

3 Claims.

This invention relates to a lug hanger for use in connection with looms.

As is, Well known, lug hangers heretofore and now generally used in connection with the picker staffs of looms are constructed of leather and anchored to the wooden picker stafis by screws extending through the body of the hanger into the staif thereby weakening the latter. The leather type of lug hanger is not durable, as it wears out easily and oftentimes breaks resultmg in materially reducing the output of weaving as a discontinuance of the operation of the loom is required to enable the substitution of a new hanger.

This invention aims to not only overcome the .objections pointed out as applied to a leather lug hanger, and also to other types of lug hangers secured to wooden picker staffs by screws, but further aims to reduce to a minimum a waste in cloth during weaving caused by breakage of they lug hanger, and to this end the invention resides in providing, in a manner as hereinafter set forth. a lug hanger of metallic material capable of being adjustably anchored to a Wooden picker staff without weakening the latter.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a lug hanger of the class referred to which is simple in its construction and arrangement, strong,

durable, conveniently anchored to the picker staff, thoroughly efficient in its use and comparatively inexpensive to manufacture.

With the foregoing and other objects inview, the invention consists of the novel construction, combination and arrangement of parts as will be more specifically described and are as illustrated in the accompanying drawing, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the invention as claimed.

In the drawing:

Figure 1 is a fragmentary view in perspective of a loom showing the adaptation therewith of the picker staff of the latter with a lug hanger in accordance with this invention,

, Figure 2 is a fragmentary View in side elevation of a picker stafi showing the adaptation 0 therewith of the lug hanger in accordance with this invention,

Figure 3 is a fragmentary view in front elevation of a picker staff showing the adaptation therewith of the lug hanger,

# Figure 4 is anexploded view in perspective of the lug hanger in accordance with this invention, and Figure 5 is a section on line 5-5, Figure 2.

A lug hanger in accordance with this invention includes a hanger member generally. indicated at I, an abutment generally indicated at 2, a clamping member 3 in the form of a yoke, a pair of washers 4, 5 and a pair of clamping nuts 6, I.

The members I, 2 may be formed of any strong, durable material other than leather and preferably the members I, 2 will be constructed of metal. The yoke member 3 will be formed of metallic material. A fragmentary portion of a loom isindicated at8 ofwhich a picker stafi 9.of wood forms a part. The coupling lug between the picker staff 9 and an operativepart of a loom 8 is indicated at Ill.

The hanger member I includes a head II substantially of semi-ovoidal contour whereby it will gradually decrease in width from its bottom to its top. The member I includes a base I2 of a width corresponding to the widest part of the head II but of a length materially less than the length of head II. The lower end or edge of head II curves downwardly from the outerto the inner 'face of the head. The upper end or edge of the base I2 curvesupwardly from the outer to the inner face of the base. The memher I includes a shank I3 of a length greater than that of the head H or base I2, but of a width corresponding, to the thickness of the staff 9.: The head II and base I2 are arranged in permanent, parallel, spaced relation on shank I3. The latter at its upper end merges into and centrally of the'lower edge of head II and at its lower end merges into and'centrally of the top edge of base I2. The head II between its transverse median and upper end is formed with a pair of spaced, parallel openings l4, I5. The openings are spaced adjacent each side of the vertical median of head II.

Formed integral with the bottom of the inner face of the head II is a pair of inwardly extending parallel spaced tapered lug confining arms I6, I! of like form. The outer side edges of the arms are flush with the side edgesof the head II. The inner side edges of the arms are spaced outwardly adjacent relative to the side, edges of the shank I3. The lower faces of the arms are flush with the bottom edge of head II. Formed integral with the inner face of the base I2 is a pair of inwardly extending parallel spaced tapered lug confining arms I8, I9 of like,

form. The tops of the arms I8, I9 at their outer ends are flush with the top edge of base I2. The outer side edges of the arms I8, I9 are flush with the side edgesof the base I2. The

5 lower edges of the arms I8, I9 are spaced above the bottom edge of base I2. The inner side edges of the arms I8, I9 are spaced outwardly relative to the side edges of shank I3. The bottom of base I2 is arranged below the bottom 10 edges of the arms I8, I9. Thearms I6, I! have their inner and outer side edges aligned with the inner and outer side edges of the arms I8, IS. The abutment member 2 consists of a stripYZII of metal substantially of a length equal to head The width of strip 20 is materially lesslthan iv that of head II but corresponds substantially to the width of the rear edge of the staff 9/ The inner face 2I of strip isfsquare. The-ends of strip 2Ilare bevelled. The strip 20 is formed 20 in its outer face with a transverse groove 22.

The strip. 20 is substantially of, segmental contour in cross section.

The member3 includes a pair of arms 23, 24 respectively-formed with peripheral threads 25,

25 26 atrtheirlfree end terminal portions. The

base 21 ofyoke member 3 is rounded.

When the lug hanger is arranged in coactive relation with respect to the picker staff 9 the memberI is positioned against the front edge 30 "of the staff 9 and with the shank I3 having its edges flush with theside edges of staff 9. The latter is disposed centrally. with respect to' the inner faces of head-II and basev I2. The staff 9 is arranged between the arms I6, I1 and between the arms I8, ,IS. The member 2 15 pcsitioned against the, rear edge 29 of staff 9 and is disposed centrally with relation tothe head Hi The base 21 of member 3 is seated in;the

groove 22 and the arms 23, 24 of member '3 extend respectively through the openings: 1!; I5 and project from the outer face of head'I I. The washers 4, 5 are mounted onthe free endiof thearms 23, 24 of, member 3 and abut theouter face of head II The clamping nuts Ii, ,1. are

home whereby thenhanger member I andabutment member 2 are clamped to the picker staff 9. -As the yoke member 3, is detachably connected to the members I, 2, the said members may be positioned: at any point desired with respect'to the length of-' the staff 9. H

The lug III of the loom which coacts withthe lug hanger, in accordance with this invention', is extended around the shank I3 and staff. 9 and is-arranged between the arms I6, I! and arms I8, I9. The arms I6, I! and I8, I9' arrest the lengthwise movement of lug I 0 relative to the staff 9 and the hanger member l.

The means, forming elements of the lug hangenfor clamping the latter to the picker staff does not weaken the latter and further as the members I, 2 are constructedtof metal breakage of the member I during'the operation of the loom is reduced to a possible minimum,

or in other words, it is free of the objectionreferred to in connection with the leather type hanger and this statement also applies to the member 2. 1

The lug confining arms I6, I I preferably will be of less length and of less thickness than the lug confining arms I3, I9. The bottom edges of the arms I6; II will be of *curved contour. The top edges of the arms I8, II! will be of curved contour, but oppositely curved with'ire'spect to the curvature of the'bottom edges of the'arms then mounted on "the arms 23, 24 and screwed I6, I1. The curvature of the edges referred to will reduce friction on the lug IIl during the operation of the loom. The top edge of the base I2 forms curved continuations of and coacts with the top edges of the arms I8, I9 to form supporting surfaces for the bottom edges of the interposed between and merging at one end into and centrally of the lower end of the head and at its other end into and centrally of the upper end of the base, a pair of spaced parallel lug confining arms extending inwardly from the inner face of said head for opposing the sides of said staff and a pair of spaced parallel lug confining arms extending inwardly from the inner faceof said base for opposing the'sides' of said staff, the arms on the head being-integral with the lower portion of the inner .face of thehead, the'arms on the base being integral with the upper portion of the inner face of the base, an abutment member for positioning against the inner edge of said staff and having its outer face formed with a transverse groove, said head being formed with spaced openings above :the arms carried thereby, and means seated in said groove, extending through said openings and binding against the outer face of the head for clamping the hanger and abutment members to the picker staff. s I a a 2. In a lug hanger for. use in connection with a picker staff, a one-piece'hanger :member adapted to be detachably clamped against the front edge of the staff and including a head having its lower edge curved downwardly from the outer face to the inner'fa'ce of the head, a base having its upper edge curved upwardly from the outer'to the inner face thereof,'a shank interposedbetween and merging at its upper end into ;.and centrally of the lower edge ofthe head and merging at its lower end into and centrally of the upper edge of the base, a pair of inwardly extending spaced 'parallel upper lug-confining arms for opposing-the sides ofsaid staff integral with the lower portion of the inner face of said head, the bottom edges ofsaid' arms forming flush continuations of the bottom edge 'of said head, a pair of inwardly extending parallel lower lug confining arms for opposing the sides of said staff integral with the upper portion of the inner face of said base, said lower arms having their top edges forming *flush continuations of the upper edge of the base, said head being formed with a pair of spaced openings, an abutment member for positioning against the rear edge of the staff and formed in its outer face witha groove transversely thereof, and means seated in said groove, extending through said openings and binding against the outer face of said'head for-detachably clamping the hanger and abutment members to the picker staff.
