WALTER W. I-I-ESTLEY, OF GREENSBORO, NORTH CAROLINA.`

LOOM-PICKER-STICK CHECK.

Application filed ctober S, 1919.

To all-whom t may concern.'

Be it known that I, VALTER WV. Hns'rLnY, a citizen of the United States, residing at Greensboro, in the county of Guilford and State of North Carolina, have invented certain new and useful Improvements in Loom- Picker-Stick Checks, of which the following is a specification.

The invention relates to a loom picker stick check device, andi more particularly to the class of tensioned manually adjustable picker stick checks for use in looms.

The primary object of the invention is the provision of a check` device of this character, wherein the same is mounted beneath the lay of aloom at the point of the shuttle box therein, so as to be disposed relative to the movable picker stick to retard the movement of said stick in one direction, the check device being of novel construction to permit manual adjustment thereof for the taking up of wear thereon or increase or decrease the checking action thereof upon the picker stick.

Another object of the invention is the provision of a check device of this character, wherein the same is constructed to eliminate the use of leather or other like material, as is commonly employed in looms for the checking of the picker stick, thereby avoiding` the frequent replacement of the lea-ther check and repairs thereto as is usual in the use thereof.

A further object of the invention is the provision of a check device of this character, wherein the same can be readily ar-.

ranged upon various styles of looms employing picker sticks for imparting motion to the shuttle in the process ofV weaving and will automatically operate to check the picker stick, as the said check is at all times under tension and is disposed relative to the path of movement of the picker stick to act directly thereon for checking purposes.

A still further object of the invention is the provision of a check device of this character, wherein the checking arm or member is supported for adjustment to vary the checking action thereof and the same is supported beneath the lay upon the fastener securing the shuttle box thereto, thereby avoiding the necessity of changing the construction of the loom or requiring any alterations thereto for the attachment of the check device upon its lay.

A still further object of the invention is Specification of Letters Patent.

Patented Apr.,13, 1920.

serial No. 328,708.

the provision of a check device of this character, which is extremely simple in construction, thoroughly reliableand efficient in its purpose, readily and easily adjusted, capable of being applied to a loom without requirinf skilled labor and also inexpensive to manufacture and install.

lith these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts, as will hereinafter be fully described, illustrated in the accompanying drawing and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure l is a fragmentary plan view of the lay and shuttle box of a loom, showing the shuttle therein and a shuttle check, with the picker stick check constructed in accordance with the invention, applied to the under side of the lay for checking action on the picker stick.

Fig. 2 is a fragmentary elevation, the parts being reversed with respect to their position shown in Fig. l.

Fig. 3 is a fragmentary plan view of the checking arm, showing in detail the adjusting eccentric, the pivot bolt or fastener being in sections.

Fig. 4 is perspective view of the adjusting eccentric removed.

Fig. 5 is fragmentary sectional view on the line 5-5 of Fig.. 2.

Fig. 6 is a fragmentary bottom plan view.

Similar reference characters .indicate corresponding parts through the several views in the drawing.

Referring to the drawing in detail, A designates generally a portion of the lay of a loom, which is constructed with the race, as usual, for the shuttle B, the same being of ordinary well-known construction and upon the lay is located the shuttle box C having mounted at one side thereof a shuttle check A l) of any approved type for the shuttle when received in the shuttle box C at the limit of its movement in the race upon the the present invention, comprises a checking arm 5, preferably made from hard wood, although the same may be made from any other material if found desirable and is of the required length, having formed on its longer side diagonally disposed checking surface 6, relative to the opposite straight longer edge 7, the arm near one end being formed with a suitable hole for accommou dating an adjustable eccentric. The adjustable eccentric comprises an eccentric sleeve 8 adapted to snugly lit in the hole near one end of the arm 5 and is mounted upon a bolt 9, which is passed through the lay A and secures the shuttle box C thereon, the bolt being passed through the longitudinal opening 10 eccentrically formed in the eccentric sleeve 8, which is provided with an annular external flange or enlarged hub 11 at one end thereof for a purpose presently described.

The checking arm 5 is disposed longitudi,n nally of the lay at the underside thereof beneath the shuttle boX C and is pivotally supported for swinging movement upon the eccentric sleeve 8, which is carried upon the bolt 9, passed through the lay A and connecting the shuttle boX thereto, the hub or iange end ll of the eccentric sleeve 8 being located next to the nut 12 upon the bolt 9, c

so as to provide a turn-table for the checking arm 5 as said flange or hub 11 serves as a shoulder portion for movably supporting the arm 5 to permit the same to move inwardly toward the path of movement of the picker stick E whereby the diagonal checking surface 6 of the said arm will contact with the picker stick when moved for actuating the shuttle l5 and thereby checking the picker stick on movement thereof 1n one direction.

The flange or hub 11 of the eccentric sleeve 8 has formed therein a socket 13 for accommodating a spanner to permit the manual adjustment of the eccentric sleeve 8 to shift the arm 5 the required distance toward or away from the slot accommodating the picker stick E in the klay A of the loom, so as to vary the checking action of the arm 5 upon said picker stick.

Secured to the side of the lay A upon which the checking arm 5 is mounted is a.

bowed leaf spring 14, the same being secured at one end while its opposite end is free and plays against the straight longer edge 7 of the arm 5 to tension the latter and constantly move it inwardly in the path of movement of the picker stick E so as to check the movement thereof when active upon the shuttle B to advance the same in the race on the lay A of the loom.

The spring 14 constantly maintains a tension upon the arm 5 to assure the checking of the picker stick in its movement in one direction and to hold the said arm 5 in operative relation to the picker stick, the adjustable eccentric being manually operated to move the arm for the taking up of wear upon said arm or the picker stick during the operation of the loom.

The check device, as hereinbefore described, will take the place of leather checks for picker sticks, as commonly employed in looms, thereby eliminating the use of leather as a check and also minimize repairs incident t0 the use of such leather checks.

Mounted near the free end of the check arm 5 and suitably fastened to the lay A is a guide bracket 15 in which the free end portion of said arm works and this bracket serves also as a stop to limit `the inward swinging movement of the free end of said check arm toward the movement of the picker stick E and also this guide bracket 15 prevents the sagging of the free end portion of the arm and guides it in its movement when active for checking of the picker stick.

It is thought that the construction, manner of mounting and the operation of the check device will be clearly understood and, therefore, a more extended explanation has been omitted. However, it iscontemplated that changes, variations and modifications may be made in the invention as come properly within the scope of the appended claim without departing from the spirit of the invention or sacrificing any of its advantages.

What is claimed is:

' A picker stick check of the character described, comprising a swinging arm, a des tachable pivot bolt adapted to be carried in and depending from the lay of a loom, an eccentric rotatably supported on the bolt, engaged in the arm and having a lower circular flange forming a turntable for the arm, and means for tensioning said arm.

In testimony whereof, I have hereunto affixed my signature.

WALTER W. HESTLEY.
