PICKER-STIOK FRIGTION-BUNTEB.

Application filed July 1, 1918.

To all whom it may concern:

Be it known that I, CnAnLns M. STONE, a citizen of the United States, residing at Lewiston, in the county of Androscoggin and State of Maine, have invented certain new and useful linprovenients in Pickertiltick Friction-Binders, of which the following is a specification.

This invention relates to improvements in picker stick hunters and used in place of or additional to the hunters now in use, in cluding the lay at the end of the race. It relates particularly to means for easing the end of the forward throw of the stick, thus preventing injury to the stick and at the same time interferingas little as may be with its return. It is also designed to lessen the vibration of the picker stick, especially after the stick operating cam has ceased to act, and to lessen wear on the picker stick pivot bolt. It is also designed to cause the picker to throw the shuttle straight. It is also designed to provide a picker stick hunter that is little subject to wear, is adjustable and remains adjusted after having been set. It is also designed to prevent the picker stick from flying up after it reaches the forward end of its stroke. The friction hunter can be readily adjusted to cause the picker stick to remain constantly in the center or at one side of the race, as desired.

In the drawing herewith accompanying and forming a part of this application, Figure 1 is an elevation of one end of a lay with my improved friction hunter applied thereto; Fig. 2 is a bottom plan view of Fig. 1; and Fig. 3 is a transverse vertical sectional view of Fig. 1 taken on line X-X looking to the left.

The same reference characters indicate like parts in the several figures.

In said drawing 1 is one end of the lay of a loom provided with the usual picker stick race 2 of any usual construction. My improved friction hunter is attached to theoutside of the lay, preferably two at each end, one on each side of, but below the race.

My improved device consists of a bracket or hanger 3 attachedto the lay by means of a bolt 4. The bracket is preferably ofiset, as seen at 5 and has a downwardly extend Specification of Letters Patent.

ing hunter supporting arm 6. To the inside of arm 6 my friction hunter 7 is attached preferably by a screw 8. The hunter is made of a yielding spring plate, preferably of wood, and it is suspended under the lay and directly under the race and its free end is adapted to be adjusted and held by a set screw projecting into the path of the picker stick as it moves forward in the race. The stick thus frictionally engages the face of the hunter plate and the side of the race and is more or less retarded by frictional engagement therewith until it finally comes to a stop, preferably just before it strikes against the lay at the end of the race In most cases l have found it better to use two similar hunter plates, one on each side of the race, their free ends projecting toward each other. The distance between the hunter plate and the lay or between the two hunter plates, when two are used, can be readily adjusted by set screws 9 to give the proper frictional resistance which can be readily determined by experiment. l/Vashers 13 of leather or other suitable material may be inserted between the ends of the ad justing set screws which tend to lessen the ar and vibration.

My invention further consists in the comhination in a single integral piece of mate rial of a picker stick friction hunter and a picker stick friction shuttle check and I have illustrated my invention in this form for convenience, the power of attachment being intermediate its ends.

lt is to be understood, however, that my invention may be embodied in a form having only the hunter friction check, in which case it will be attached to the bracket carrying plate as before.

The operation of my hunter check and its adjustment is readily apparent from the drawing and the foregoing description. The picker stick should pass a considerable distance out of contact with the hunter check and then frictionally engage the adjacent faces thereof, and the hunter check should be preferably adjusted so that the resistance to the forward throw of the picker would gradually increase until it just lightly reaches the end of the race, thus obviating at the ends and secured at points that are a greater distance apart than the ends, With means intermediate the ends and the points 10 of attachment for varying the distance between the free ends.

In testimony whereof I atfix my signature.

CHARLES M. STONE.
