JOHN C. EDVARDS, OF BROOKLINE, MASSACHUSETTS, ASSIGNOR TO DRAPER COMPANY, OF HOPEDALE, MASSACHUSETTS, A CORPORA- TION OF MAINE.
SHUTTLE-CHECKING MEANS FOR LOOIVIS.
SPECIFICATION forming part of Letters Patent No. 778,646, dated DeCember 27, 1904. Application iiled July 8, 1904. Serial No. 215,707.
To r/,Z iff/mnt it Duty concern:
Be it known that I, JOHN C. EDWARDS, a citizen oi' the United States, and a resident otl Brookline, county of Norfolk, State of Massachusetts, have invented an Improvement in Shuttle-Checking Means for Looms, of which the Jfollowing description, in connection with the accompanyingdrawings, is a specification, like characters on the drawings representing like parts. i
This invention relates to means for checking and stopping the shuttle of a loom when home in the shuttle-box, so that the shuttle may be positioned as nearly as possible at the same point pick after pick; and the invention has for its object the production ot' novel means for exerting checking pressure upon the shuttle, whereby the checking and stoppage ot' the same will be eiiiciently and accurately accomplished.
In the present embodiment of my invention the checking pressure is exerted upon the shuttle independently of the binder, which accordingly is mainly employed to control the usual protector mechanism with which looms are equipped, and a light protectorspringI can be used. This enables the shuttle to be readily moved in the shuttle-box to accommodate itself to properly receive an in coming filling-carrier when the loom is provided with mechanism to insert a fresh llingcarrier into the shuttle when necessary to replenish the filling.
In order to adapt my novel checking means to such an automatic loom, which may be of the Northrop type, as embodied in United States Patent No. 529,940 and of others of later date, I have provided means whereby the shuttle is automatically relieved of the checking pressure when such filling replenishment is effected.
The construction and operation of the pressure-producing means is such that any tendency of the shuttle to rebound is neutralized.
The various novel features of my invention will be fully described in the subjoined specification, and particularly pointed out in the following claims.
Figure I isa top or plan view of one end of the lay of a loom with a shuttle-box thereon and having one embodiment of my invention applied thereto, the shuttle being shown as boxed, and the construction is arranged for the replenishing-box of an automatic fillingreplenishing loom. Fig. 2 is a transverse sectional detail on the line 2 r2, Fig. l, showing also a portion of the replenishing mechanism. Fig. 3 is a top or plan view of the pressure producing or checking member detached. Fig. I is a perspective view of the angularly-movable support on which the said member is eccentrically pivoted, and Fig. 5
is a detached plan view of the bunter by or through which said support is angularly moved to relieve the, shuttle from checking pressure when filling replenishment is effected.
The lay A3, picker I), binder B, fulcrumed on the lay at 5X and acted upon by the usual binder-linger Z1, carried by the protector rockshat't Fig. 2, the binder having aswell B and the shuttle-box having a fixed front wall I7, cover-plate 17X, and back wall 30, may be and are all of usual construction and operate in well-known manner.
In Fig. 2 I have shownl a portion of a filling-feeder or hopper F to support a series of n'lling-carriers or bobbins b1", a transferer f to insert them one by one into the automatically self-threading shuttle S when the lay is at or near its front center, the dog m, which operates the transferer being moved into the path of the bunter C2 on the lay when filling replenishment is called for all substantially as in the patent referred to, the movement of the dog m being controlled by the rock-shaft cl in well-known manner.
The lay is provided with two bearing-brackets l and 2, extended rearwardly therefrom (see Fig. 2) to support an upright angularlymovable support or stud 3, (shown separately in Fig. 4,) the reduced lower end of the stud extending below the bracket 2 and having secured to it by a set-screw 4 the hub 5 of an L-shapedbunter 67. The arm 6 of the bunter is long enough to extend the bunter well in toward the center of the loom, so that the arm 7 thereof, which is extended forward beneath the lay, will not be in theway of the pickerstick or of a filling-carrier when ejected from the shuttle. The arm 7 is provided with an upturned shoulder 8 to abut against a bearing 9 secured to the under side of the lay, the arm 7 sliding loosely through this bearing. spring 10, 1 and 2, connected at one A end j the incoming shuttle and it controlsv the usual protector mechanism for the loom; but inasmuch as the main checking and stopping of the shuttle is effected by the member 13 a light binder-spring can be utilized.
In practice the retracting-spring 18 will be to the bearing and at its other end to the arm j made strong enough to instantly turn the 7, acts to hold the shoulder 8 against the bearing in the normal position shown. The stud 3 has a circular head 11, which rests on the top of the bracket 1, and an eccentric pivot pin or post 12 is upturned from this head. This eccentric forms the center on which the pressure-producing member turns, said member being shown as a rather thick circular disk 13, provided with an eccentric hole 14, Fig. 3, to loosely receive the post 12, the checking member being retained on the post in any suitable manner, as by a nut 13 screwed onto the post. An arm 15, extended rearwardly from the cam-like checking` member 13, is connected with one end of a strap 16, which passes outward around the picker P and is fastened at its other end to the front wall 17 of the shuttle-box, and a spring 18 (shown in Fig. 1) is fastened at one end to the back of the lay and at its other end to the arm 15 to swing the latter in the direction of the arrow 19 until the arm engages a stop-pin 2O on the bracket 1. WV hen the picker is thrown inward to ejectthe shuttle S from the box, the strap 16 is slackened and the spring 18 instantly turns the member 13 on its center 12, releasing the shuttle and retaining the checking member inoperative until the shuttle again enters the box. Then the impact of the incoming' shuttle upon the picker throws it outward, the strap 16 is tightened, and it acts through the arm 15 to turn the check 13 on its pivot 12 in a direction opposite the arrow 19 and into locking engagement with the side wall of the shuttle.
When the pressure-producing member 13 is in its inoperative position, its periphery is moved out of the path of the shuttle owing to the eccentricity of the member 13; but when the latter is turned into operative position, as described, its periphery is brought into engagement with theside of the shuttle with an increasing pressure as the cam is turned farther round until the shuttle is stopped.
It will be seen that the direction of rotation of the checking member is opposite to the movement of the shuttle, and if the latter tends to rebound it will then cause the checking member to increase its wedging action and eectually prevent any rebound.
The binder B is cut away or recessed, as at 35, (see dotted lines, Fig. 1,) to permit the checking member 13 to pass through and engage the shuttle-wall, the checking action of said member being directly exerted upon the shuttle and operating wholly independent of the binder.
The binder serves as an initial check upon checking member in the direction of the arrow 19, Fig. 1, to release the shuttle when the picker is thrown inward to throw the shuttle out of the box.
So far as the operation of the checking means applies to an ordinary loom or to the non-replenishing shuttle-box of an automatic loom it will be manifest that the pivot on which the checking member 13 is mounted eccentrically may be rigidly mounted on the lay; but when theloom is provided with mechanism to automatically insert a filling-carrier in the shuttle the checking means at the replenishing shuttle-box must include provision for automatically relieving the shuttle from checking pressure during replenishment.
In an automatic loom when filling replenishment is called for the usual controlling rock-shaft CZ, Fig. 2, is turned in the direction of arrow 40 and elevates a dog (Z2 into 1 position to engage the bunter-arm 7 and push the latter back as the lay approaches front center, the shuttle having been checked just before. The upright stud 3 is angularly moved in its bearings and the post 12 is moved rearwardly and somewhat toward the outer end of the lay, thereby carrying bodily the checking member 13 away from the side wall of the shuttle and relieving the latter of checking pressure, so that it is free to move and accom- IOO modate itself to the incoming filling-carrier when filling replenishment is effected. By this movement of the post 12 I avoid tightening the strap 16, it being manifest that it would not do to tighten the strap in order to release the check, because such tightening would act to pull the picker inward and push the shuttle away from the outer end of the shuttlebox. By means of the set-screw 4 the bunter 6 7 can be adjusted on the stud 3 to increase or decrease the angular movement of said stud to relieve the shuttle of the checking pressure. The rather broad peripheral face of the checking member prevents any scoring or cutting action on the side of the shuttle when the checking pressure is exerted thereupon. By the adjustment between the bunter and the stud 3 I am also enabled to vary the checking action, for if the outward movement of the picker upon impact with the shuttle is substantially constant the adjustment of the pivot-pin 12 away from the shuttle-path will tend to decrease the checking pressure and adjustment toward the shuttle-path will increase it, as then the wedging action of the checking member upon the shuttle will be augmented.
