2b all whom 'it may concern:

Be it known that I, JONAS NoR'rHRor, a citizen of the United States, residing at Hopedale, in the county of lVorcester and State of Massachusetts, have invented an Improvement in Shuttle-Boxes, of which the following description, in connection with the accompanying drawings, is a specification like letters on the drawings representin like parts.

he invention to be hereinafter described relates to looms, and more particularly to the means employed for bringing the shuttle to rest in the shuttle box at the end of its picking movement.

As well understood by those skilled in the art, the shuttle is picked or thrown from one side of the la to the other in laying the llin in the she and, as it passes into the shu e box, it is not only desirable that it be gradually brought to rest in proper po- 'tion in the box, but that it be not deflected from its straight course as it passes into the box under the control of the checking means.

'With these facts in mind, the aims and urposes of the present invention will best he understood and made clear from the following deseri tion and accompanying drawings of one orm or embodiment of means for carrying the invention into effect and seeurin the objects above stated, it being understood that the invention is not restricted to the details shown, but is definitely setfortli in its true scope by the claims.

In the drawhi Figure 1 is a plan or top View of a s uttle box embodying the present invention, only so much of the adjacent loom parts being shown as are necessary to make clear the association and action of the invention therewith; F ig. 2 is a section on the line 2-2, Fig. l; and Fig. 3 is a view similar to that of Fig. l, some of the ports being in section or broken away, and the shuttle being indicated :is having fully entered the box.

Mounted on the luy beam l is the fixed wall 2 extendin in prolongation or in the lane of the reed and forming a part of the ack wall of the shuttle box. Adjustnbly secured to the lay beam is the front wall 3 of the shuttle box, said front wall being preferably provided with the slotted lugs 4 which are engaged by bolts 5,-whereby said A front wall is secured in position. It will .Y be noted that the front wall 3 has its inner or shuttle engaging surface formed slightly flaring at the ent-rance to the shuttle box, said flaring portion G extending from a point 7, between which and the surface of the back wall 2 the dimension of the shuttle box is substantially the same as the exterior dimension of the shuttle. From the point 7 to the terminal portion 8, the shuttle en a g surface of the front wall of the shutetdx is arallel to the inner surface of the back wa b2, the construction bei such that as the side of the shuttle ridesriong the inner surface of the back wall 2 of the shuttle box and contacts with the inner surface of the front wall at the point 7, the shut-tle continues to travel in a straight course Vand glides straight into the shuttle box, avoiding any side deviation or blow by the rear end of the shuttle against the reed or rear wall of the shuttle box even after the shuttle comes under the influence of its checking means, as will presently appear.

liovable ,longitudinally in the bottom slot 9 of the shuttle box is the picker stick l0, of any usual character, the end rtion only of said stick being shown, an on or connected to the picker stick is the icker 11 having a shuttle engaging seat 12, 1, and by which the shuttle is given its icking movement, as well understood. I desired, a cushion or buffer 13 may be connected to the outer portion of the shuttle box against which the picker stick may rest prior to its picking movement.

The. shuttle binder comprises the body portion 14, refer-ably formed of wood or other desir-eil material, terminating at its inner end portion in a tongue 15, against the exterior surface of which bears the binder finger 1G for controlling the dagger 1T in a manner well understood by those skilled in the art, the construction and relation of parts being such that when the shuttle binder is forced buck by the entering shuttle, it. will more the binder linger 16 and rai-:sc the da ger 17 so that in the beatup movement. o? the lay the dagger will not engage the trip member of the knockoli' mechanism, as usual; but should the shuttle fail to enter the shuttle box suiicieiitly far to thus move the binder, or if it should undulv rebound, then the binder will fail to be held in back position as the lay i beats up, with the result that the binder .i finger will not lift the da ger, and the latter will knock-olf the oom, in the well understood manner.

Passing throu h the outer end ortion of the lay beam ors uttle box is a bo t 18 preferably passinor also through a lug 19 of a bracket 20 an the top plate of the shuttle bx, substantially as indicated by Fig. 2, whereby the top plate and bracket20 :nay be conveniently secured 1n place, it being understood that while this assemblage of parts is a goed practical form of means, yet the invention is not restricted thereto.

In the presented form of the invention the outer end portion of the binder is preferably made of metal, cast or otherwise formed, with the elongated slot 21 which loosely embraces the lug 19 of the bracket 20, Figs. 1 and 3, and having the front and back walls 22 and 22", respectively, between which the body rtion of the binder 14 projects, and to w ich it may be seciued by suitable fasteners or screws 23 and 24 or otherwise, as will be clear from Fig. 3. For

ur ses of identification this 'end of the Eindzi', which is connected to the lay beam or shuttle box, may be called the binder head, it understood that the term is used in its road sense for purposes of designation only.

Screw-threaded into the back portion of the binder head is an adjusting screw 25, the end of which may be positioned in the elongated slot 21, to vary the amount kof lae and forth monentuof the pinder ea for a urpose t wi present y appear, a locli) nut 26 being preferably ernployed to hold the adjusting screw in adusted 'tion irojectiiiogS1 rearward from the end of the lay beam or shuttle box is the bracket arm 20, having the post 28 through which ex tends the screw 29, the inner end thereof being received by a cap piece 30, and a lock nut 1 being preferab y em loyed to maintain the-screw 29 in ad}ust position. Disposed between tlie ca piece 30 and the seat 32 on the binder head 1s the tension spring 33, the construction being such that while the binder` head is movable toward and from the plane of the front wall of the shuttle box y reason of the elongated slot 2l, it is normally resisted in such movement by the spring 33, as will be evident.

The binder has a swell or inwardly extending portion 34, which, when the shuttle is not in its box, projects into the shuttle box, Fi 3, under the action of the sprin 33 and ginder finger, and the end of the a justing screw 25 bears upon the adjacent portion of the bearin lug 19, said screw and the tongue 15 thus eterminin the normal position of the binder when t e shuttle is 5 not in its box.

As well understood by those familia-1' with the art, it is desirable to bring the shuttle gradually to rest in )roper position in the shuttle box without shock or injury thereto, und while thc ordinary swell contributes to this end itis not always satisfactory for well known reasons. In the present invention the outer end portion or head of the binder is connected to the lay by the shifting fulcrum and is provided with the cani surface 35 adapted to act upon the side of the picker 11, as the latter is moved to the end of its outer position by the incoming shuttle, and, as the picker is conned to travel in a straiht line, the binder head is moved back against the direct action of the sprin 33, imparting to the picker a progressive y increasing retardation as the picker nieves along the cam surface 35 to the end of its travel. It will be evident, of course, that the retarding effect of the binder head upon the picker may be varied bv adjusting the tension of the s ring 33, and that the amplitude of outwardp movement, and pel-force the retardin eiect of the binder head, may be further a justed by means of the screw 25.

The present invention is not intended to be confined to the details illustrated and described as one form of means for carryinv it into practical effect, as it ma be modified in various ways by those skilledy in the art.

From the characteristics of the invention as hereinbefore announced, it will be noted that as the shuttle enters the box it will move in a straight course into position between the back wall and the point 7 of the front wall, and as it meets the swell 34 of the binder its straight course will not be altered, but the binder will move pivotally about the luv 19 as a. center, thus acting through the abinder linger 16 to raise the dagger. As the shuttle meets the picker, which is at the time located approximately as indicated in Fig. l, it will cause the picker to move to the right, Fig. 3, with the result that, as the icker moves along the cam surface 35 of t 1e binder head, the latter will he moved outward against the tensionof the spring 33, imparting throuvh the pickera procressii-ely increasing retardation to the shutte movement as the picker approaches the end of its outward travel. During this outward movement of the binder head, the binder will turn about a point on the swell in cont-act with the shuttle, but, as the binder swell has its shuttle contacting portion relatively near the inner end part of the binder, such action will not interfere unfavorably with the proper action of the binder finger, and tbe parts will come to rest in substantially the relative position indicated by Fig. 2. It will also be noted that the shuttle contacts with the binder at the binder swell only and that the final checking action of the binder operates through the 'picker und not directly on the shuttle exco t in so far asi-.outward movement of the inderhead may increase the action of the binder'swell.

The action ofthe cam 35 on the picker is liable to 'cause the picker stick to be'v deflected sidewise toward the o posite wall of the slot 9. As one means o counteracting this tendency, the wall of the slot 9 opposite the cam 35 is faced with a suitable material, such as leather 36, Fi 1 and 2, which may be preferably thinne toward the in ner end of the shuttle box, as indicated in Fig. 1, to properly resist the side thrust of the pam 35 on the picker stick. Obviously7 also the binder and front wall of the shuttle box may be faced with any desired material, such as leather.

From the described embodiment of the iiivention it will be seen that the binder is mounted on a. shifting ulcrum; that the slot 21 in the binder head is made of suitable dimension to permit the binder head not onl to move directly outward against the action ,of the spring 33 in the manner stated, but also to swinfr the necessary amount about the lug 19. tlt will also be noted that as the picker stick moves to the outer portion of its stroke the guiding slot 9 narrows to maintain the icker stick in proper position and to enab e the cam 35 to act effectivgly upon the picker in checking the shutt e.

That is claimed is:
