12 Claims.

rest motion of the shuttle as it enters the shuttle box. Many of these binders are pivoted on the [lay and swing outwardly from the shuttle box when engaged by the shuttle. the shuttle causes it to vibrate and also produce This swinging of oscillations in the shuttle as th latter enters the shuttle box.

- It is an important object of the present invention to provide a shuttle binder mounted in such manner that it can yield as the shuttle enters the .box but without the aforesaid pivoted motion,

thereby enabling the surface of the binder to remain in contact with the shuttle throughout the motion of the latter in the shuttle box. The

shuttle binder has a surface which is substantially parallel to the back wall of the shuttl box fixed to the lay and this surface moves forwardly throughout its entire length because of the mannor in which th binder is mounted.

fIt is another object of the invention to mount the binder on elastic links which may be made of rubber so disposed as to permit a limited endwise motion of the binder in the same direction in which the shuttle is moving. These elastic mountings are also compressible and enable the binder to mov bodily transversel of the shuttle as it checks the shuttle. The elastic feature of the mounting links enables the binder to cooperate effectively with any one of several shuttles which may be of slightly varying widths.

It. is a more specific object of the invention to provide soft elastic mounting links the ends '01 which are preferably non-circular so that they 'can fit into holders on the" lay and also into recesses in the binder. The non-circular ends of the mountings can also be cemented to their holders and to the binder if desired to avoid wear, the yielding feature being confined largely to that part of the mounting between its ends.

The mounting links for the binder to b described in more detail hereinafter, due to their elasticity, return the binderto its normal position after a shuttle is picked out of the box and also serve as the sole support for the binder so that the usual binder pivot pin and binder spring are eliminated.

With these and other objects in view which will appear as the descriptionproceeds. the. invention resides in the combination and arrangmentjof parts hereinafter described and set forth.

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

Fig. 1 is a plan view of alshuttle box and adjacent parts of the lay having the improved binder and mounting therefor shown in the position corresponding to a boxed shuttle,

Figs. 2 and 3 are enlarged vertical sections on lines 2-2 and 33, respectively, Fig. 1,

Fig. 4 is an enlarged fragmentary view of the rear end of one of the elastic mountings and of the adjacent part of the binder,

Fig. 5 is a perspective view of one of the elastic mountings,

Fig. 6 is a diagrammatic view illustrating the manner of operation of the invention when a shuttle is being boxed,

Fig. 7 is a view similar to Fig. 6 but showing the manner in which the shuttle binder operates when a shuttle is being picked out of the shuttle box, and

Figure 8 is a diagrammatic view of one of the links shown in Fig. 6 on an enlarged scale.

Referring to Fig. 1', the loom lay in is provided with a shuttle box wall Ii held in fixed position with respect to the lay and defining in. the present instance the back part of a shuttle box designated generally at I2. A picker l3 of usual construction is provided to pick or actuate'the shuttl S. The latter may be the only shuttle in the loom or it may be one of several shuttles which are called into action one at a time. If several shuttles are used there is likelihood that there will be a slight variation in their width. The lay will be'actuated in the usual manner, a part of one of the lay connectors for that purpose being shown at M.

The matter thus far described may be of common construction and except as noted hereinafter forms no part of the presentinvention.

In carrying the present invention into effect a binder 20 is provided for the front of the shuttle. This binder may be made of wood or any other suitable material and has its rear surface lined with a friction facing 2!, such as leather, which has direct engagement with the shuttle. The box plate 22 of the loom may have a pair of forward extensions 23 each of which supports a housing designated generally at 25. Each housing has right and

left walls

26 and 21 joined by a front wall 28. A short rear wall 29 may extend from the left wall 21 toward the right Wall. 26 and with the latter define an opening 30.

The binder mountings 35, see Fig. 5, are made in the form of inherently elastic links each havin 3 afront head 36 which fits into one of the housings 25. Extending diagonall rearwardly and toward the center of the loom from the head is a shank 31 which leads to a second head 38 which may be substantially of rectangular form as indicated in Fig. 4. This head 38 fits into'a complementarily formed recess or pocket 39 in the binder 20. If desired the heads 36 and 33 can be cemented to the corresponding enclosing structure, but such cementing will not be necessary in all forms of the invention.

Each housing has a base 40 formed at either side thereof with back and forth extending slots 4| through which extend holding bolts A2.

extend through the box plate generally in the direction of the length of the lay. Nuts 44 on the lower ends of the bolts serve to hold each housing in firmly fixed position with respect to the box plate 22, but because of the slots 4! and 43 it is possible to adjust the housings angularly with respect to the box plate 22.

Both of the mounting links 35 are made of a resilient material, such as a soft elastic rubber, and tend normally to hold the binder in the position shown full lines in-Fig. 6, i. e., with the binder in shuttle engaging position .and toward the center of the lay. As the shuttle enters the The' latter extend downwardly through slots 43 which return to a position of repose locate the binder normally in a correct position for the start of a shuttle checking operation, and as the shuttle moves into the shuttle box [2 it will by its frictional contact with the facing 2| cause some endwise outward motion of the binder which will place the shanks 31 under compression thereby causing the binder to exert a frictional force against the shuttle to bring the latter to rest. If there is any variation in width in the shuttles used in the loom the shanks 31 will compress an amount to accommodate such variation. The housings for the mounting links are secured to the box plate 22 for adjustment relatively thereto either angularly, longitudinally, or transversely with respect to the shuttle box. The links 35 are the sole support for the binder and the latter can shuttle bOXgit has frictional contact with the binder and moves it toward the outer end of the lay, or in the same direction in which the shuttle is moving, to the dotted line position shown in Fig. 6. During this movement of the binder the mounting links 35 will be subjected to some com-' pression due to the fact that the normal distance between the leather facing 2| and the box wall H is Slightly less than the Width of the shuttle. As the binder moves endwise the two links 35 will move from the full line position shown in Figs. 6 and 8 to the dotted line position, i

the effect of this motion being to lessen the distance between the heads 36 and 33 to produce the aforesaid compression in the links. Also, the heads 38 move to the right relatively to the heads 36 and the'links bend on themselves, see Fig. 8.

It is obvious that if there is slight variiation in the width of the shuttles used in the looin the shanks 37 will be compressed by varying amounts depending upon the variation in shuttle width, the wider shuttles causing the greater compression.

When the shuttle is picked out of the box as suggested in Fig. 7 its frictional engagement with the. binder will move the latter inwardly or to the left as shown in full lines against a stop 45' secured tothe lay. During this operation the elastic links will move from the dotted to the full lineposition, Fig. 7, but as soon as the shuttle has left the box the links 35 due to their elasticity will move the binder to the right, r'e-' turning it to the dotted line or normal position of Fig. "7.

The leather facing 2! will ordinarily be substantially parallel to the box Wall E l, but the adjustments' 'pr'ovided "for the housings will permit a change in the position of the binder so that if desired its outer'or right end as viewed for instance in Fig. 1 can be slightly closer to the box wall I I than its inner or left end.

From the foregoing it will be seen that the invention provides a binder which is mounted on inherently elastic links the forward ends of which are held in fixed position with respect to the lay and the rear ends of which are fastened to the binder. These links by their tendency to be mounted and held in normal checking position without the customary pivot pin or binder spring.

Having thus described the invention it will be seenthat changes and modifications of the foregoing specific discoslure may be made without departing from the spirit and scope of the invention.
