4 Claims.

This invention relates to improvements in shuttle binders for looms and it is the general object of the invention to provide a mounting for the binder which will permit the latter to move relatively to its support to assume such positions as will best adapt it for checking the shuttle.

The usual binder pivots about a pin or stud fixed to the lay during boxing of the shuttle. The fit between the binder and its pivot is rather close 0 and the binder swings in a plane perpendicular to the stud and is unable to adjust itself to slight Variations in the walls 'of the shuttle it contacts. Under proper shuttle checking conditions the shuttle engaging surface of the binder should 3.; fit closely against the wall of the shuttle which it engages so that the maximum friction can be exerted onthe shuttle. When several shuttles are used in a loom it is difiicult to maintain the correct shuttle-binder contact with known binder :3 supports. It is an important object of my presem invention to provide a flexible element between the binder and its support which will permit the binder to move angularly in a vertical direction to adapt itself to the shuttle and effect close contact between the shuttle wall and'the binder surface.

When a shuttle is boxed it exerts an outward longitudinal thrust on the binder which is'tran'smitted'to the pivot stud and the latter has a tend- 3 en'cy to wear and also work loose. At the time of picking the stud is subjected to a similar-force but in the opposite direction because of the drag of theshuttle along the binder. It is a further object of my present invention to provide a 1 mounting for the binder which will permit the latter to yield slightly in a direction along the path of the shuttle and relatively to itssupport. In constructions heretofore used the outer end.

of the binder has been held relatively tightly 0 with respect to the shuttle path because of its pivotal connection and as a result of this relation considerable time has been'required in adjusting the position of the stud so that the binder will not be either too loose or too tight. It isanother object of my present invention to employ a 5 =be attained --by" placin'g arnass of rubber between the binder and its support. I have shown this mass of rubber in the form of a bushing surrounding the stud and carried by the binder but I do not wish to be limited to this particular form of mounting for the mass of rubber.

With these and other objects inview 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 drawing, wherein a .cono venient embodiment of my inventionis set forth,

Fig.1 is a plan view of a shuttle'bo'x havin'gmy invention applied thereto,

Fig. 2 is a vertical section on line 2-2 of .Fig. 1 showing a shuttle having a vertical binder en- -13", gaging front wall,

Fig. 3 is a'view similar to-Fig. 2 but showing the binder in. engagement with a shuttle the front Wall of which is inclined, and

Figs. 4, 5, 6 and 'I are diagrammatic views 13 showing different positions of the binder with respect to its supporting stud made possible by the use of my'invention.

Referring .tothe drawing,I have shown a loom lay L having a box back I!) forming part of the shuttle'box'design'ated generally at. B. The shuttle in the form of the inventionshown' herein shown in Fig. l is'for illustrative purposes only.

The front of the shuttle box has extending therealong a shuttle binder 2B the inner or left end of which engages a protector finger 2|. A

spring 22 held'to the lay by a bolt 23 yieldingl-y holds the binder in rearward position against a stop 24. The shuttlemay :be of any approved U construction and as shown :at S in Figs. .1 and '2 will have a front. wall 25whic'his vertical. The

.shuttlemay however be replaced by another shuttle S as indicated in-Fig. 3 which will have-a front wall 26 inclined either by designer as the result of uneven Wearing.

The box plate 12 has extending therethrough a binder supporting stud. 30 which'may be though not necessarily formed as indicated in Fig.2.

' The upper end'of the stud has'a bearing shank 3| L below which is a collar 32 of larger diameter than the :shank to rest on the plate I2. Extend- .ing downwardly from the collar is a threaded stem 33 .passing through the .plate I2 :to be :held impositioniby:ainut 34. ".The :hoxv plate -.-:may be 1 provided with a slot 35 permitting adjustment of the stud 30 toward and from the box back ID. A washer 3B and cotter pin 31 of usual construction may be supplied for the upper part of the shank 31.

The parts thus far described may be of usual construction except as modified by the following description. It is to be understood that the invention can be applied either to a loom operating with one weaving shuttle or to a, so-called drop box loom operating with two or more weaving shuttles which are active one at a time. When two shuttles are used for instance they may be of the form shown at S and S in Figs. 2 and 3, respectively.

In carrying my present invention into effect I provide the outer or right end of the binder with an enlarged hub 40 having a relatively large bore 4|. Into this bore I insert a bushing 42 of soft rubber made to yield under a deforming force but sufiiciently resistant to withstand the usual pressures of the binder without excessive deformation. The bushing may rest on the collar 32 as shown in Fig. 2 if desired and may be cemented or otherwise fastened to the hub 50 so that the bushing and the binder constitute a unit which is rotatable about the stud 39. While I have shown and described the particular arrangement just set forth I do not wish to be limited necessarily to a bushing secured to the binder.

The bushing has a bore 45 to receive the shank 3! with which it has a close fit. I have found in practice that satisfactory results are obtained if the fit permits turning of the bushing with respect to the stud, but I do not wish to be limited to this construction inasmuch as the bushing can be secured to the stud as by direct vulcanization thereto. The essential condition is to establish a body of yieldable deformable material between the binder and its support and this condition can be met either by having the bushing tight or loose with respect either to the binder or the stud so long as provision is made to preserve the parts in an operative relationship more or less as set forth in Fig. 2 or 3.

In the boxing of the shuttle the first contact of the shuttle with the binder tends to move the latter outwardly or in the same direction in which the shuttle is travelling. At the time of picking the binder will be subjected to a force tending to move it in the opposite direction, or in the direction in which the shuttle is propelled. The binder is therefore acted upon by two oppositely directed forces tending to move the binder in directions parallel to the lay. Spring 22 ordinarily holds the binder in the path of the shuttle and the latter is moved forwardly or in a direction away from the box back I!) when the shuttle is boxed. This forward motion extends throughout the length of the binder and exerts a forward force toward stud 30.

In the operation of my invention the resilient bushing absorbs part ofthe forces to which the binder is subjected and undergoes various deformations dependent upon the direction of the forces exerted on the binder. In Fig. 4 is illustrated a condition existing when the shuttle is boxing, the binder having moved slightly in the direction in which the shuttle is travelling to cause a compression of that part of the bushing between the stud 30 and the left part of the hub l as designated at a. In Fig. 5 I illustrate the reverse condition which exists when the shuttle is picked out of the box, at which time the binder will tend to move toward the center of the loom with the shuttle to cause a deformation of the bushing resulting in a compression of the latter at b to the right of the stud 30. During boxing of the shuttle the binder will move forwardly and a slight compression of the bushing will occur at c, Fig. 6. When the box is empty the bushing will be subject to the pressure of spring 22, which however is negligible and the stud will be in the center of the bushing as indicated in Fig. 7.

The bushing, however, is not limited to the types of deformation thus far described but can alter its shape in a tendency to equalize pressures to which the binder is subjected. This is illustrated in Fig. 3 where the front wall of the shuttle S is shown as inclined, a condition may exist because of an intentional shaping of the shuttle or because of wearing. Under these conditions the binder will rock in a vertical plane so that its shuttle engaging surface 58 can take an oblique position enabling it to have contact throughout its length and height with the shuttle. The oblique position of the binder will result in upper and lower compression zones (1 and e, respectively, in the bushing. By this relationship the shuttle and binder can have close shuttle checking relationship despite the fact that the stud 3D is fixed with respect to the box plate and may be oblique with respect to the front wall of the shuttle. This condition is particularly useful in shifting shuttle box looms wherein several shuttles become active successively and wherein the shuttles will not always be of exactly the same shape, or in shuttle changing looms employing a complement of shuttles.

From the foregoing it will be seen that I hav provided a mounting for a shuttle binder of such nature that the binder is floated on a body of resilient or cushioning material supported by the lay and because of its floating support is able to assume a variety of positions to suit differently shaped shuttles. It will also be seen that I have provided a mounting which absorbs some of the longitudinal forces directed against the stud 30 as the result of boxing and picking of the shuttle. Furthermore, the bushing can be deformed as shown for instance in Fig. 6 to permit slight variations in the widths of the various shuttles which enter the box. These shock absorbing features and adaptability to varied shuttle conditions together with reduction of wear on the stud 30 are all accomplished by the resilient bushing 42. As stated hereinbefore I do not wish to be restricted to the particular form of the cushion or block of resilient material interposed between the binder and its support, since the particular adaptation of the invention shown in the drawing does not constitute the only means by which the advantages set forth can be achieved by the floating of the binder on a mass of inherently resilient material.

Having thus described my invention it will be seen that changes and modifications may be made therein by those skilled in the 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:

1. In a loom having a lay and a shuttle box thereon to receive a shuttle, a binder carried by the lay and extending along and forming part of the shuttle box to engage the shuttle and resist entry thereof into the shuttle box, a support for the binder carried by the lay, and a mass of rubber located between the support and the binder and deformable .by a force transmitted through 7 the binder to permit the latter to assume a plurality of positions relatively to the shuttle box. 2. In a loom having a lay and a shuttle box thereon to receive a shuttle, a binder carried by the lay and extending along and forming part of the shuttle box, a support for the binder carried by the lay, and a mass of soft and elastic resilient deformable material located between the binder and the support and constituting a resilient mounting between the binder and support and yieldable because of the inherent resilience thereof to permit the binder to move bodily with respect to the support in all horizontal directions;

3. In a loom having a lay and a shuttle box thereon to receive a shuttle, a binder carried by the lay and extending along and forming part of the shuttle box, a support for the binder mounted on the lay, a mass of inherently soft and elastic resilient material between the support and the binder, the latter having a vertical surface to engage a vertical Wall of a shuttle in the shuttle box and said binder because of the inherent resilience of said mass of material being movable in a vertical plane to effect close contact between the vertical adjacent surfaces of the shuttle and binder.

4. In a loom having a lay and a shuttle box thereon to receive a shuttle, a binder carried by the lay, a stud mounted on the lay to support the binder, and a rubber bushing surrounding the stud and interposed between the latter and the binder and compressible to permit relative movement of the binder with respect to the axis of the 15 stud.
