DOUBLE DUTY BINDER Filed Aug. 22, 1958 a INVENTOR. lljl/fldm H Knox o Patented July 4, 1939 UNETED STATES PATENT OFFICE DOUBLE DUTY BINDER Application August 22,

6 Claims.

This invention has to do with binders such as are commonly employed in looms for the purpose of holding the shuttle after each pick.

The problem of providing a binder that will properly receptively engage and hold a shuttle after each pick is extremely important, particularly when the loom is of the automatic type which involves the automatic replacement of bobbins in the shuttle. In the first place, proper receptive engagement of the shuttle with the binder insures of the shuttle assuming a straight position. This is advantageous both from the aspect of providing even wear on the shuttle, and in the making of the subsequent pick. Furthermore unless the shuttle is properly positioned and firmly maintained in that position there is a strong tendency for the automatic replacement of the bobbins to be attended by such results as broken shuttles, bobbins and other damaged parts.

With the foregoing conditions in mind this invention has in view, as its foremost objective, the provision of an improved and novel binder for shuttles which is characterized as providing for highly improved receptive engagement of the shuttle with the binder, as well as an improved and novel arrangement for firmly holding the shuttle in position.

In carrying out this objective the invention has in view, as an important feature, the replacement of the old wood and leather type binder with an all metal binder having a polished surface that engages the shuttle.

A further object of the invention is the provision of an improved binder of the character above noted together with means for mounting the same on the shuttle box of the loom to provide for an improved floating motion on the part of the binder. Particular objects and advantages of the invention are associated with the provision of this means for providing the improved floating motion.

In the looms of present day construction the general practice is to provide a pressure finger adjacent the innermost side of the shuttle box for engagement with the binder to apply pressure thereto, which urges the same against the shuttle at a zone more closely adjacent to the picker. With this arrangement there is a tendency for the outermost nose of the shuttle to become displaced and assume a position that often causes disastrous results as the bobbins are changed.

Accordingly, this invention has in View, as another highly important object, the provision of 1938, Serial No. 226,094

a binder of the character above described which has associated therewith a so-called auxiliary binder which is effective to engage the shuttle adjacent its outer nose, under pressure, to firmly position the shuttle.

Another more detailed object of the invention is the provision of an auxiliary binder of the character above noted which is so arranged with respect to the main binder that the application of pressure on the main binder in the usual manner by the conventional pressure finger is rendered eifective to cause application of pressure by the auxiliary binder.

Various other more detailed objects and advantages of the invention will in part become apparent and in part be hereinafter stated, as the description of the invention proceeds.

The invention, therefore, comprises a novel binder which includes means for mounting the same on a shuttle box to provide and improved floating action, and an auxiliary binder associated therewith for applying pressure on the shuttle adjacent to its outer nose.

For a full and more complete understanding of the invention reference may be had to the following description and accompanying drawing, wherein:

Figure 1 is a plan view of a shuttle box having the improved binder of this invention associated therewith,

Figure 2 is a side view of the structure shown in Figure l, and

Figure 3 is a diagrammatic view bringing out the relationship of the parts when the shuttle is out of the box.

Referring now to the drawing, wherein like reference characters denote corresponding parts, the end of a lay is designated IE) and is shown as having an opening at H (dotted lines, Figure 1) through which used bobbins pass from the shuttle i during the automatic replacement thereof. The lay In constitutes, in effect, the bottom of the shuttle box. At one side the lay l0 carries a box back in the form of a plate 52 which preferably is of metal having an inner polished surface with which the shuttle engages. At one end the lay i H and box back 42 carry a box end identified at I3, and this box end houses the picker in the usual manner.

Carried by the lay it? and spaced the required distance from the box end 13 is a bracket referred to in its entirety by the reference character B. This bracket B includes a bottom plate l4 that extends outwardly from the lay IE1 and from which upstands an outer strut l5, and an inner wall l6 that is covered with leather, as shown at IT, to constitute the same a hunter.

Connecting the strut l5 and wall 16 at the top is a cover plate 18. A pivot pin l9 extends between the bottom plate l4 and cover plate 18, and mounted on this pivot pin I9 is the auxiliary binder referred to in its entirety by the reference character 20. This auxiliary binder 20 takes the form of a bell crank having one arm at 2i and another arm 22 that is of a bent formation and having a rounded extremity at 23 for engagement with a shuttle. The bottom lower edge of the arm 22 is cut away to provide a recess 9 for a purpose to be hereinafter pointed out.

The usual safety finger which is included in looms of this type is referred to generally at 24, and the arm 2i of the auxiliary binder 20 is adapted to engage therewith when the shuttle is seated in the box in the usual manner.

The improved binder of this invention is referred to in its entirety by the reference character 20. In accordance with this invention the binder preferably made from a single bar of metal and is formed with the main body portion 2 that carries, at the end adjacent to the box end it, an end flange 2? that is formed with a slot 28. The slot 28 terminates in an end wall 28 formed with a threaded opening that carries a set screw A nut 35 is in turn carried by this set screw 36. The inner end of this set screw 30 projects into the slot 28 for a purpose to be hereinafter pointed out.

A bracket 32 is secured to the box end l3, as by the screw and nut shown at 33 and this bracket 32 has a turnedout flange 2 3 from which projects a lug 35 that extends through the slot 28. A cotter pin shown at 3% serves to maintain the assembled relationship of the binder end 27 and the bracket 32. At the same time the floating motion on the part of the binder is provided for by the slot 28 and lug 35, and the amount of motion permitted may be varied by adjusting the set screw 39.

At the front end the binder 25 is formed with a so-called offset arm 3! which is integrally connected with the main body portion 26 by the inclined part 38 that is formed with a. slot 39 through which a feeler (not illustrated) is adapted to pass. The arm 31 is reduced in width, as compared to the main body part 26, and passes through the recess 9 in the arm 22 of the auxiliary binder 28.

At this point it is well to note that the binder will be made from a metal adapted to present a polished inner surface, the inner surfaces of the parts 26 and 38 being polished, as it is with the inner surfaces of these parts that the shuttle is adapted to engage. It is also important to note that the lower edge of the binder 25 is maintained in upraised spaced relationship from the lay ii as is clearly depicted in Figure 2. VJhile the spacing may be varied within reasonable limits the invention contemplates an arrangement wherein the spacing is substantially one quarter of an inch.

It is important to note that the offset arm 37 of the binder 25 extends between the strut l 5 and wall N3 of the bracket B, and normally engages the arm 2! of the auxiliary binder 20.

The usual pressure finger included in the looms is referred to generally as 46, and, as shown inv the drawing, this pressure finger engages the main body part 26 of the binder 25 at a point closely adjacent the box end IS.

A shuttle is referred to generally by the reference character S and may be of the usual type now meeting with use in automatic looms. The operation and mode of functioning of the improved binder of this invention may be described by noting that with the shuttle S out of the box, the binder 25 and auxiliary binder 20 will assume the positions depicted in Figure 3. Under this condition pressure is not applied by the pressure finger All to the binder 25, nor is the arm 2i in engagement with the safety finger 24.

With the shuttle moving into the box end the sides of the shuttle engage the polished surfaces of the box back l2 and binder 25, and with the shuttle seated in the position shown in Figure 1, pressure is applied by the finger 40 to the main. body part 25 of the binder 25. This pressure causes the inner surface of the main flat body part 26 to align with the corresponding flat surface of the shuttle S, thus causing an outward movement on the part of the arm 31, and the engagement of the latter with the arm 2i of the auxiliary binder iii causes this arm 2i to move outwardly to engage the safety finger 24 and continue the operation of the loom in the usual manner.

At the same time the arm 22 of the auxiliary binder is moved inwardly so that its rounded end 23 firmly engages the shuttle adjacent its inner nose. Thus the shuttle is firmly held at two spaced points, one adjacent each nose. The position of the various parts when the shuttle is so held is shown in full lines in Figure 1.

The above described binder presents a distinct advantage over the usual wood and leather type binders that heretofore have met with widespread use in this art in that the metal will wear many times longer than will the leather which has heretofore been employed on the inner sur face that engages the shuttle. Another distinct advantage of the metallic binder above described is that the frictional resistance encountered at each side of the shuttle is substantially the same, as the resistance on each side is caused by engagement with metallic surfaces. Thus when the shuttle is received in the box it will have a tendency to assume a straighter position than is the case when the old wood and leather binders are employed.

The binder of this invention presents the further advantage of prolonging the life of the picker, as there is less friction of the shuttle as caused by the binder which must be overcome by the picker in throwing the shuttle on its next shot.

Another highly important advantage of the metallic binder of this invention is that it may be bent to any required shape so that it may be peculiarly adapted to use with any particular type of shuttle.

The slot bearing providing for the connection of the flanged end 27 to provide the floating action presents a distinct advantage over now known connections for providing this floating action in that the slot 28 and lug 35 have interengaging bearing surfaces of appreciable length, which serve to aid in maintaining the binder in proper position, particularly in holding the face of the binder straight at all times. Thus when the shuttle engages the binder the face of the binder is substantially parallel with the side wall of the shuttle, and no force is required to align these surfaces.

Furthermore, by providing the adjustable set screw 30, the amount of floating action on the part of the binder may be accurately controlled and adjustment made to adapt the floating action to any particular size shuttle which is being used.

With the shuttle held in position by the main body portion of the binder 25 at one end, and the arm 2i of the auxiliary binder Ed at the other, change of bobbins may be automatically carried out without danger of damaging the shuttles, bobbins or yarn.

The use of a metallic binder of the character above described is particularly desirable from the viewpoint that the collection of dirt and grease, which is inherently present with the wood and lea 191 binders, is greatly diminished, if not substantially eliminated.

With the lower edge of the binder 25 spaced above the lay 50 greater freedom on the part of the thread carried by the shuttle is provided for, and this is particularly true at the time of changing bobbins.

Another advantage afforded by the double grip that is provided for by the binder 25 and auxiliary binder 29 is that the shuttle is gripped at both ends. Thus the wear on the shuttle is more even and the tendency of the shuttle to wear down more at the eye end than at the other is substantially eliminated.

The metallic binder of this invention is adapted to be substituted for binders or" the Wood and leather type which are now meeting with use on automatic looms, and when substituted therefor have been found to increase the efficiency of production to a marked extent.
