Description
UNITED STATES v Patented February 16, 1904.
PATENT OFFICE.
PICKER-SUCK GHI-:CK FOR Looms.
SPECIFICATION forming part of Letters Patent 550-752,110, dated February 16, 1904.
l Application filed September 5, 1903. Serial No, 172,062. (No model.)
- T a/ZZ whom t may con/cern,.-
Be it known that I, WILLIAM E. SARTWELL, a citizen of the United States of America, and a resident of North Troy, county of rQrleans, and State of Vermont, have invented certain new and useful Improvements in Picker-Stick Checks for Looms, of which the followingis a specication.
My invention relates to devices for providing a yielding stop to check the picker-stick in its outward movement; and the object of my invention is to provide a means for cushioning the picker-stick check in its outward movement, and thus relieve the shock at the sudden stopping of the shuttle as it shoots through the shuttle-race and comes in contact with said stick. I accomplish this object by means of the mechanism illustrated in the accompanying drawings, in which- Figure l is a perspective view of my pickerstick and its attachments, the lathe or batten of the'loom being shown in dotted lines illustrating the position of the picker-stick and connections in connection with said hatten. Fig. 2 is a perspective view of the end plate and plungers. Fig. 3 is an end elevation of the stop-plates. Fig. 4 is afront elevation of the stop-plates, partly in section.
Similar letters refer to similar parts th roughout the several views.
I arrange a picker-stick A in reference to the battens B B in the usual position to throw the shuttle in the ordinary manner, the pickerstick being pivoted at C in any convenient way. To the under side of each of the adjacent battens B B', between which the pickerstick A reciprocates, I secure the Shanks D D of the stop-plates E E, respectively. The stop-plates E E being placed at such angle to the battens B B as the picker-stick A makes to said batterie when the picker-'stick is in its .normal position before being acted upon by the shuttle.
I preferably arrange on that portion of the stop-plate Eifacing the shanks D D retaining-anges e, adapted to engage and hold in position a block F, preferably of wood.
I arrange an end plate G, in connection with which I place a cushion, preferably a leather strip g, against which the picker-stick A is forced by 'the action of the shuttle, the plungers H H lpassing through the end plate Gand the cushion g and through enlarged openings t in the stop-plate andI through corresponding openings in the block F. The end of each plunger is preferably threaded, carrying a nut or other suitable adjusting retaining device J, which is preferably provided with a hook j and also, if desired, with, a lock-nut K. On the hook j' I placeone end of a link L, which is preferably of leather, the other Yend of said link L being secured to one end ofthe spring S, the opposite end of said spring S engaging with a hook M or other suitable device for fastening it to the under portion of the hatten B. As thus arranged and connectedup the cushion g, in connection with the end plate Gr, rests against the stop-plate E, held in position by the tension of the spring S. The pickersticl A in its movement under the iniiuence of the shuttle will press forward and downward upon the cushion g, and the movement of the lplungers H will be free from unnecessary friction. As the spring S is near to the under surface of the hatten at its end farthest from the picker-stick than at the point of its connection with the link L, the plungers H, being at right angles to the end plate G and said end plate arranged to make the same angle with the under surface of the batten that the pickerstick does, the movement of the picker-stick will cause a movement of the end plate and cushion attached thereto forward and outward, describing a short arc of a circle of which the pivot of the picker-stick is the center. Thus the spring is acted on in the direction of its length and no opportunity for unhooking is provided, which would Vperhaps occur if the pull on the spring were notin the line of the longitudinal axis of the spring, the enlarged opening inthe stop-plate E permitting easy movement of the plunger therethrough. 1
By placing the block F in connection with the stop-plate and making the opening through the blockF smaller than the enlarged opening It in the plate E such friction as takes place is that exerted upon the block F by the plunger, which block is preferably constructed of wood or other fibrous material, instead of on the IOO plate E,Which is metal. I thus provide for a direct strain upon the spring.- By arranging the connection between the plunger and the spring of leather or similar material I do 5 away with any friction at that point. By placing the cushion g on the end-plate Gr, I lessen any ill-effect Jfrom the shock of the picker-stick acted upon by the shuttle.
I arrange for altering the tension of the IO spring S by means of the nuts J K or either of them if but one is used.
The picker-stick strikes the cushion flat, preventing the stick or the cushion from being marred,and forces outward and downward the I5 end plate and cushion directly againstV the tension of the spring S. In the return the eXact reverse takes place, the end plate and cushion bringing' the picker-stick to its normal position directly and without undue friction.
`What I claim as my invention, and desire to secure by Letters Patent, is-
1. In a picker-stick check for looms, the combination of a batten', a picker-stick pivoted at one end; a stop-plate; a shank secured to said stop-plate or formed integral therewith; said shank secured to the under surface of said batten; said plate formed at such angle to said batten as the picker-stick makes with said batten when in its normal position, before being acted upon by the shuttle; aV block of fibrous material secured to said stop-plate;
said `stop-plate and said block provided with means for adj ustably securing one end of said spring to said plunger; means for securing the other end of said spring' in such position that the last-mentioned end of said spring shall be nearer the under surface of said batten than the end of said springadjacent to said plunger, substantially as described.
2. In a picker-stick check for looms the combination of a batten; a picker-stick pivoted at one end; a stop-plate secured to said batten and adjusted to make the same angle to said batten that the picker-stick makes with said hatten when in its rearward position; 'a block of resilient material removably secured to said stop-plate; an end plate; a cushion on said end plate; a plunger passing through said stop-plate and said block thereon; a spring suitably supported; a means for securing said spring to said plunger, all substantially as described.
Signed at North Troy, Vermont, this 26th day of August, 1903.
