PICKER-STIGK CHECK.

Specification of Letters Patent.

Patented Aug. 19,1913.

Application filed May 12, 1913. Serial No. 767,037.

To all whom, it may concern Be it known that I, HENRY BRUNELLE, a citizen of the United States of America, and resident of Ware, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Picker-Stick Checks, of which the following is a full, clear, and exact description.

The object of this invention is to provide a check device with which the picker stick coacts upon its retiring movement which is especially well adapted to fulfil the purposes for which such devices are designed for cushioning the picker and minimizing the destructive effect thereon of the shuttle in its motion toward and against thepicker.

The invention is described in conjunction with the accompanying drawings and is set forth in the claims.

In the drawings :--Figure 1 is a side elevation showing the picker check as mounted on and carried by the rocking support for the lay and in its relation to the picker stick a portion of which and some of its appurtenances are shown. Fig. 2 is a side elevation; Fig. 3 a vertical elevation or edge view, and Fig. 4 a plan view of the picker check itself and as removed from the support in the loom therefor; Fig. 5 is a horizontal sectional view through a pivotally jointed part of the device as taken on the line 55, Fig. 3.

Similar characters of reference indicate corresponding parts in all of the views.

In the drawings, 10 represents the rockshaft on which the lay (not shown) is carried and by which the picker stick 12 is also carried, the same being secured to the rocker 13 which acts in the usual way relatively to the fiat topped extension 14 of the rockshaft,15 representing a portion of the strap by which the picker is forcibly thrust or swung for its shuttle impelling movement, and 15 representing a spring including retiring device for the picker, these parts being assumed to be as usual in looms of the most common type and of most extensive use.

Now as regards the picker stick check which as will be perceived is an attachment to be secured to and carried as a part of the rocking support for the lay, A represents a bracket adapted to be rigidly secured on the lay support as by having at the lower portion thereof a recessed lug or confining member a which matches with and by a bolt is secured to a suitable lug formed as a depending part of the aforementioned fiat topped extension of the lay carrying rockshaft. This bracket at its rear side and near its attachment portion a is made with a shoulder Z1.

The bracket is formed with an upwardly and outwardly extended portion d, offset from the plane of which is the aforemen tioned shoulder Z) which shoulder, or abutment is formed as a top wall of the attachment member.

Near the outer extremity of the portion d of the bracket A is a slot f horizontally extending from a rearward to a forward direction relatively to the line or plane of swinging movement of the picker stick.

B represents an angular lever having a transverse hole 9 through its elbow portion 6 as represented in Fig. 5, and a bolt h or other appropriate pivot forming member is passed through the said hole '9 in the lever and through said slot f and has combined therewith means whereby such bolt may be confined on said bracket at any place in the length of the slot. Said lever comprises, as an extension from its elbow an upstanding arm 5 having a transverse lug or abutment j to be engaged by the picker stick in the retractile movement thereof; and said lever also comprises an arm m here represented as curved, extending horizontally and then downwardly and adapted to have a motionlimiting engagement with the shoulder 22 formed as a part of the bracket.

70 represents a retractive spring applied to the said elbow lever B for maintaining the upstanding arm in a normal forward or inward position, and as limited by the engagement of the other arm {m with the shoulder 11. The curved arm m has an upwardly and rearwardly extended lug 0 and the lower portion of the bracket has a rearwardly extended lug 79 at quite a distance below the one 0 to which lugs the eye formed ends of the aforesaid mentioned spring 70 are attached,all in such manner that the spring will be stretched when the lever-like picker check member is swung outwardly from its normal position, in which latter position the spring tends to maintain it.

As a special and entirely practical and satisfactory means for efiecting the adjustment of the check lever pivot lengthwise of the slot f, and for the confinement of the parts in adjusted position, the hole through the elbow of the check lever is comparatively large, the same receiving therethrough an annular bushing 3 having a flange 6 at its end adjacent the rear face of the bracket portion (Z.

The length of the bushing in a direction rearwardly from said flange is slightly greater than the distance transversely through the lever elbow which portion of the latter for sufficient length of the bearing is made with the extension hub 10.

A washer o overlies the outer face of the bracket across the slot; and the bolt 72', the head of which is in engagement with the washer 11 passes through the slot and through the bushing and receives at its end opposite the head the binding nut w which through the medium of the washer exerts its confining action for the bolt against the end of the bushing effectively holding such bushing in confinement in whatever position along the slot it may be adjusted, but in no way tending to bind or impede the freest possible swinging movement of the check lever on the bushing which is sleeved over the bolt.

As manifest, the check lever may be bodily adjusted inwardly or outwardly relatively to the bracket so as to be positioned for its most advantageous checking of the picker; and such check lever is thereby most properly conditioned as a factor for the cushioning of the picker stick which is required to withstand the many time repeated impacts of the loom shuttle.

I claim 1. In a picker stick check, the combination with a bracket adapted to be mounted on the support for the lay comprising a shouldered attachment portion and a rearwardly and upwardly extended lever-supporting member located in a plane offset from said shoulder forming attachment member, having a slot extending in a rearward to a forward direction, of an angular lever having a transverse hole therethrough at its elbow portion, and a pivot member passed through said perforation and said slot and having means appurtenant thereto whereby it may be confined on said bracket at any place in the length of said slot, said lever comprising an upstanding arm having an abutment to be engaged by the picker stick in its retiring movement and an arm adapted to have a motion-limiting engagement with the shoulder of the attachment part of said bracket, and a retractive spring applied to said elbow lever for maintaining the upstanding arm in a normal, forward, position as limited by the engagement of the other arm with the said shoulder.

2. In a picker stick check, the combination with a bracket adapted to be mounted on the support for the lay and having an angularly extended lug, of an angular lever, pivotally mounted on said bracket, comprising an upstanding arm having an abutment to be engaged by the picker stick in its retiring movement and an arm adapted to have a motion-limiting engagement with a part of said bracket, said arm having an a-ngularly extending lug, a retractive spring between and secured to said lugs and operative to maintain the upstanding arm in a normal, forward posit-ion as limited by the engagement of the other arm with the said bracket, the said angular lever being forwardly and rearwardly adjustable on the bracket, and means for confining such lever in adjusted position.

Signed by me at Springfield, Mass, in presence of two subscribing witnesses.
