-3 Claims.

This invention relates to shutue 'checking mechanisms for looms and it is the general object it can move Atoward and from thepath traversed by the shuttle. v'The binder is ordinarily in the shuttle path and offers resistance to the shuttle as the latter enters the 'shuttle box. Shuttle 'binders'of the floating type are so mounted that each'end can move toward and from the shuttle path, but vsuch bindersarenot ordinarily made in` such a way that they can be readily moved away from the shuttlepath to relieve pressure on the shuttle. It is an` important object of my present invention to provide an improved form of binder Ahaving a handle made as a part thereof to facilitate binder movement -when the shuttle is to`be moved out of the shuttle box manually.

It is customary-to apply spring pressure to the inner and outer ends of floating binders, these pressures being f different degrees so that the inner end which cooperates with the protector mechanism will move outwardly away from the shuttle path as soon as the shuttle enters the box. As the shuttle continues to travel into the box the outer end of the binder isfmoved away from the shuttle path. It is another object of i my present invention to provide the binder with a handle extendingalong the binder for such a distance that eitherlthe inner or the outer end of the binder can be moved away from the shuttle path depending upon the point at which the withdrawing force is applied to the handle.

In looms operating'iwith two or more shuttles it is customary to provide a gang of shuttle boxes which are stacked one over the other in close vertical relationship. Because 'of this relationship it has been'dif'cult in the'past'to manipulate the binders manually, andit is another object of my invention to provide the binder with a handle of .less vertical dimension 'thanthat of the binder so 4'that each'binder'will have ahand hold readily accessible without'undue interference on the part of an adjacent'binder.

With theseandother objects in View which will appear as the description proceeds, my invention resides in the combination and arrangement of'parts hereinafter described and set forth.

In the accompanying drawings, wherein a convenient embodiment of my invention is set forth,

Fig. e is 'a detailed enlarged section on 11nelB-B, Fig. 1, but with the shuttle-box parts'omitted, and

Fig. l 'is a detailverticalsection von line '1 -1, Fig. 1.

Referring particularly'to Figs. 1 and'2,`I have shown a lay L'having a lay 'end -l in whichla gang G of shuttle boxes is 'guided vfor vertical motion. The'inner end of the gang hasa tongue li received by'a llay carried guide l2, and the outer endof the gang may be provid-ed witha similar `tongue [3 tting into afguide lil. As shown in FigeZ the lower end of the gang G is connected to a box lifter rod l5 which is moved vertically by box shifting mechanism not Shown. A protector finger Bof the usual type is provided adjacent the inner end of the gang G and -normally exerts a rearward force toward Ythe lay end Il).

Each ofthe upper and'lower shuttle boxes I8 and I 9 is provided -withsabinden these binders being indicatedat v2li and 2|, respectively, inFig. 2. Eachbinder is made preferably oi wood and has a leather friction surface 22 and an inner end '23 formed `for cooperation with the protector nnger I6. The outer end of eachfbinder is formed with a pocket 24 the rear or inner end of which maybe providedwith 'a shockabsorbing pad 25 made for V'instance of leather.

A bracket is secured as at 3| to the gang and has a forward extension 32 which iismore or 'with spring bearings`35. Check nuts 36 serve to hold each of the screws 33 'and 34 in adjusted po-l sition. Each binder thas Vassociated therewith a compression spring 40 the rear end of 'which lenters the vcorresponding pocket 24`and the'forward end of which is held by the associated bearing 35. The outer or left end of each binder as viewed in Fig. 1 is therefore moved rearwardly is adjustable independently of the other stop and has the adjacent end of the corresponding binderV held against it by the associated spring 45. The inner end of the shuttle boxes carries an angle iron stop 49 which cooperates with stops 45 and 46 to limitr endwi-se movement lof the floating binders.

In order that wardly in order to relieve pressure on the corre'-` sponding shuttle the front edge of each binder is cut as indicated in Fig. 5 to provide an elongated handle or knob 5B. This handle is of less vertical dimension than the binder to provide ample room between the handles of adjacent binders forthe operators fingers. Behind each handle are top and bottom recesses 5l and 52 for the operators fingers. y l

Figs. 3 and 4 indicate Adiagrammatically the manner in which either the inner or the outer end of a binder can be moved. In Fig. 3 arrow and springa represent the resilient rearward force exerted on the binder by the spring'40, while the arrow and spring b represent the resilient rearward force exertedvby the protector finger I6. Arrow c indicates the point at which the weaver will grasp the handle 50 if he wishes to move the inner or right end of the binder forwardly to the dotted line position shown in Fig. 3. In the relationship indicated in Fig. 3 the leverage and yielding forces represented by a andb will result in movement of the'i binder to the position in dotted lines. In this position the protector nger has moved forwardly while the outer end of the binder and spring dllhave remained normal.

In Fig. 4 the force for moving the binder forwardly has been moved to the left and is applied at a point adjacent to springAU, as indicated by arrow d. In this case the binder will move to the dotted line position of Fig. 4 with its outer end advanced, and with the protector finger in normal position. It will be seen that the handle is sufficiently long to permitV the weaver to Y. pull itforwardly by Yapplying a force on it either near the center of the binder or near the spring 40 depending upon whether it is desired to move the inner end of the binder or the outer end thereof forwardly.

From the foregoing it will be seen that I have provided .a simple form of shuttle binder made with a, handle to facilitate its forward movement. It will also be seen that the handle has avertical l dimension less than that of the associated binder sothat when the vbinders are vused in a gang of shuttle boxes each binder can be moved'forwardly V- readily without interference` on the part-of adjacent binders. Also, Yit will be seen that -the handle is of sufficient length so that Yeither the inner or the outer end of the binder can be moved forwardly. It is to be understood of course that after the binder assumes either vof the dotted line positions shown in Fig. 3 or 4 a. further forward application of force to the vhandle will move the each binder may bemoved forbinder as a whole to a Yforward position. 'Fur- Y thermore,`it will be seen that each binderhas its Y seen that changes and modifications may be made therein by those skilled in thev art without departing from the spirit and scope of the invention and I do not wish to be limited to the details herein disclosed, but what I claim is:

Y 1. In .a shuttle box for a loom having aprotector iinger, a binder extending along said box and having one end thereof in engagement with the protector nger, a spring mounted on said rshuttle box andengaging the other end of theA binder, said protector finger and spring normally holding the binder in the shuttle box for engagement with a shuttle, said spring exerting a greater force on the binder than said protector finger, and a handle integralwith the binder and extending along the latter between the protector finger and spring and being of such length that when a force is applied to the end'thereof adjacent to said spring theA latter will be overpowered while the protector finger remains normal, and when ra force is applied to the end of the handle nearer the protector finger the latter will'be overpowered while said spring remains normal.

2. In a shuttle box for a loom having a protector finger, a oating shuttle binder, said protector finger engaging one end of the binder and urging said end rearwardly into the shuttle box, a spring mounted'on the shuttle box and engaging the other end of the binder and urging the latter rearwardly into the shuttle box, and a handle formed integral withsaid binder and located on the front part of the latter and extending from a point adjacent to said spring along said binder other end thereof, said binder including an elongated body of wood and having one end thereof formed for engagement with the protector Vnger for movement thereby and having the other end thereof formed to slide along said guide and having means to cooperate with said spring mecha-Y nism for movement by the transverse force exerted by said mechanismvand aV handle formed integrally with said wood body extending therealong between said one end of the binderand V'said means at said other end of the binden Y CLIFFORD DARWIN.
