8 Claims.

This invention relates to multiple shuttle looms and more especially to an improved attachment for preventing idle filling yarns which extend from the adjacent selvage of the cloth being woven to a vertically reciprocable multiple cornpartment shuttle box from becoming entangled with each other or from being drawn into the fabric being woven by an outgoing shuttle.

As is well known to those familiar with the art, as a shuttle is thrown across the lay of a loom into one of the compartments of a vertically reciprocable multiple compartment shuttle box, there is disposed between the adjacent selvage and the multiple compartment shuttle box a portion of filling yarn. The shuttle box may then be elevated or lowered according to the desired pattern and a shuttle from another compartment will be thrown out of the multiple compartment shuttle box across the lay after which this shuttle will be thrown back across the lay to return to the same compartment. Now, as the secondnamed shuttle is thrown out of the corresponding compartment in the multiple compartment shuttle box, the portion of the yarn from the previously cast shuttle which extends between the selvage of the cloth of the fabric being woven and the shuttle box may be pulled back into the woven material or fabric or may become otherwise entangled with these previousl cast portions of the filling yarn which may subsequently sever these portions of the yarn requiring that the loom be stopped, and in the event of the yarn being drawn into the fabric being woven, it re sults in defective fabric and a substantial loss,

It is therefore an object of this invention to overcome such defects as heretofore described by providing an individual automatic means operatively connected to the shuttle box for elevating each of the yarns as the shuttle in the corresponding compartment is elevated and to thereby permit any shuttles therebelow to be thrown across the lay without encountering the previously cast filling yarn or yarns.

It is another object of this invention to prm vide a simple and efficient means which operates independently of the usual operating mechanisms of a loom and which not only serves to elevate the yarn extending from a corresponding shuttle as the shuttle box is elevated, but to also clamp previously cast portions of the yarn which extend between the selvage of the cloth being woven and the shuttle box and which may be connected to shuttles disposed below the herl zontal plane of the lay and to there-by, also, pre" vent the yarns extending from lowered compartments from being folded back into the shed,

(Cl. Bil-170.6)

More specifically, it is an object of this invention to provide a plurality of spring biased fingers which are pivotally mounted on a multiple cornpartment shuttle box, there being one of these fingers disposed adjacent the lower surface of each of the compartments and the uppermost of these fingers normally being biased upwardly while those fingers therebelow are normally biased downwardly and each of the fingers being provided with suitable stop means to limit their movement in the direction in which they are biased with the result that, as the shuttle box moves upwardly from the lowermost position, the uppermost finger will move upwardly therewith as the compartment therebelow is alined with the upper surface of the lay and. upon a compartment below said second compartment subsequently being positioned in alinement with the race plate of the lay, the corresponding finger which has heretofore been biased into engagement with the upper surface of the lay or with a suitable notch provided in the lay for reception thereof, will move upwardly to substantially the same horizontal plane as the lower surface of the corresponding compartment to thus also elevate this yarn therewith so as not to be affected by the operation of the shuttle disposed therebelow. On the other hand as each of the shuttle boxes moves downwardly, the corresponding finger moves downwardly and engages the upper surface of the portion of filling yarn extending between the selvage and the corresponding one or more of the compartments disposed therebelow to thus clamp this filling yarn between the lower surface of the corresponding finger and the upper surface of the lay,

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings in which- Figure l is a perspective view showing a por tion of a vertically reciprocable multiple compartment shuttle box on one end of a lay and showing the improved yarn separator means in association therewith;

Figure 2 is a top plan view of the structure shown in Figure 1;

Figure 3 is a vertical sectional View taken substantially along the line 3-3 in Figure 2 but omitting the shuttles from the corresponding compartments and also omitting the filling yarns;

Figure 4 is an elevation similar to Figure 1 but showing the filling yarn from the shuttle in the top compartment of the shuttle box extending to the selvage of the fabric being woven.

Referring more specifically to the drawings,

3. the numeral it! indicates the conventional lay of a loom which is suitably secured to the upper portions of a pair of spaced swords II, only one of which is shown in the drawings. Each of the swords I I has a pitman pin I2 therein to which the front end of a pitman rod I3 is pivotally connected, the rear end of this pitman rod I3 being connected. to the crank on a conventional crank shaft of the loom, not shown. Spaced above the lay it is a suitable reed cap I6 which is suitably secured to the corresponding swords IE and disposed between the reed cap I6 and the lay I is a suitable reed 16a forwardly of which is disposed a conventional race plate I? which is suitably secured to the upper surface of the lay.

It will be observed in Figures 1, 2 and 4 that the race plate is cut away to provide a notch or cavity I9 therein, the bottom of which, in this instance, is defined by the upper surface of the lay I6 although it is to be understood that the cavity I9 need only be of such depth as to accommodate the forwardly and rearwardly extending portions of the separator fingers or wires to be later described.

The end of the lay shown in the drawings is provided with the usual lay end casting I8 and in which one end of a conventional protection rod 2| is oscillatably mounted. This protection rod 2| has a conventional pressure arm 22 fixed thereon and extending upwardly therefrom and which is adapted to engage the free ends of a plurality of binders 23 which extend outwardly and are pivoted by conventional means, not shown, and are pressed inwardly at their free ends to properly box the corresponding shuttles by conventional springs indicated at 26 in Figure 3. These binders 23 are parts of a conventional vertically reciprocable multiple compartment shuttle box comprising side plates 26 and 21 and having a plurality of horizontal partitions 28, 29, 36 and 3i and a bottom 32 which define four shuttle receiving compartments A, B, C and D.

The reed cap I6 is provided with a conventional shuttle guard 35 which extends from one end thereof to the other and which constitutes no part of the present invention. The upper end of the pressure arm 22 is biased rearwardly or towards the shuttle box by conventional spring means, not shown, associated with the protection rod El, and in order to limit outward movement of the binders 23, there is provided a combined stop and support member indicated at d2 which is suitably secured, as by welding, to the front box plate 26 by legs 63 and 44. This combined stop and support member 32 has a plurality of horizontal portions 65 for assisting in guiding the free ends of the binders 63. The parts heretofore described are the usual parts of a multiple shuttle loom and it is with these parts that the present invention is adapted to be associated.

It will be observed in Figures 1 and 4 that a suitable bracket or plate 56 is suitably secured, as by bolts to the front surface of the front plate 26 and adjacent the end of the shuttle box nearest the selvage of the cloth fabric being woven. The bracket 56 is threadably penetrated by a plurality of vertically spaced bolts, three of which are shown in the drawings and which are indicated at 54, 55 and 56. Suitable lock nuts 5'! are provided on the inner ends of these bolts.

Collars 66, 6E and 62 are oscillatably mounted on the respective bolts 54, 55 and 56 and it will be noted that these collars are eccentrically mounted on the corresponding bolts 54, 55 and 56 so as to provide portions thereon which are penetrated by respective separator fingers 65, 66 and 61, these fingers 65, 66 and 67 being suitably secured in the corresponding collars 60, 6| and 62.

It will be noted that each of these fingers extends inwardly towards the center of the lay and it curves upwardly and then downwardly and these fingers 65, 66 and 6! are provided with rearwardly extending portions 65a, 66a and 61a, respectively, which are adapted to, at times, rest in the cavity I9 in the race plate I'I. It might be stated that each of the fingers 55, 66 and 67 is curved in the manner described between its respective collar and the corresponding rearwardly extending portions 65a, 66a and 61a so as to provide a generally upwardly curving portion which extends slightly above the upper surface of the race plate I 1 when they are in a lowered position and also extends upwardly when they are in a raised position to thus retain the filling thereon during rearward movement of the lay.

Since the rearwardly extending portion 65a of the uppermost finger 65 would never have occasion to move upwardly beyond the horizontal plane of the bottom 29 of the upper compartment A as the shuttle box is moved to a lowermost position, the upper separator finger 65 is biased upwardly by a suitable torsion spring 10, one end of which encircles the portion of the upper separator finger 65 adjacent the collar BI! and the other end of which is disposed in one of a pair of transverse slots 72 in the head 13 of the bolt 54, the medial portion of the torsion spring 70, of course, encircles the bolt 54. It will be observed in Figures 2 and 4 that a portion of the separator finger 65 projects through the collar 66, to the left in Figure 4 and normally engages a suitable stop pin 15 secured in the plate or bracket 50 and which is provided to limit upper movement of the free end of the separator finger 65 so that the forwardly and rearwardly extending portion 56a thereof is normally disposed at substantially the same horizontal plane as the bottom 29 of the upper compartment A.

It might be stated that the uppermost separator finger 65 is normally biased upwardly so that, as the shuttle box is moved upwardly to its uppermost position, the rearwardly extending portion 65a thereof may engage the lower surface of the reed cap to thus cause the finger 65 to move in a clockwise direction in Figures 1 and 4 and will thus not interfere with upward movement of the shuttle box. However, if the reed cap I 6 does not extend outwardly to where it will extend above the vertical plane of the rearwardly extending portion 65a of the upper separator finger 65, then the upper separator finger 65 would not have to be biased in either direction and could remain in fixed relation to the bottom 29 of the upper compartment A.

The collars 6! and 62, which are oscillatably and eccentrically mounted on the bolts 55 and 55 have the respective fingers 66 and 61 projecting therethrough in off center relation. These fingers are normally biased downwardly to cause the outer ends of these separator fingers 66 and 6? to normally engage respective stop pins 83 and 66 suitably secured in the bracket 50. The separator fingers 66 and 6'! are normally biased downwardly at their free inner ends by respective torsion springs 80 and 81' which encircle the respective bolts 55 and 56.

One end of the torsion spring 80 is bent around the finger 6t adjacent the collar 64 and the other 5 end thereof is disposed in one of a pair of transverse slots 8! in the head 82 of the bolt 55. One end of the torsion spring 81 is secured around the finger 6! adjacent the collar 62 and the other end thereof is disposed in one of a pair of trans- 10 verse slots 89 in the head 90 of the bolt 56.

It is thus seen that the two fingers 6B and 61, are biased to cause their free ends to move downwardly but are limited as to downward movement by the respective stop pins 83 and 86, these stop pins 83 and 86 being so positioned that the rearwardly extending portions 56a and 61a of the respective separator fingers 6B and 61 will be disposed in substantially the same horizontal plane as the bottoms 3E) and iii of the respective compartments B and C in the shuttle box when these particular compartments are elevated above the horizontal plane of the race plate I1. On the other hand, as the compartments other than the uppermost compartment A are lowered below the horizontal plane of the race plate H, the lower surfaces of the rearwardly extending portions 66a and 51a of the respective fingers 65 and 61 will engage the upper surfaces of the yarns extending from the shuttle box disposed therebelow to the selvage of the fabric being woven to thus clamp this yarn against the upper surface of the lay in the notch I9 so that the yarn will not be drawn into the shed.

In the drawings, there are shown filling yarns PM and F-2 extending from the respective compartments A and B of the shuttle box to the selvage of the fabric being woven, although it is to be understood that similar filling ends would also extend from the compartments C and D, and, when the shuttle box is in the position shown in Figures 1 and i, the filling end extending from both these compartments would be clamped beneath the rearwardly extending portions 65a and 61a of the fingers 55 and 61 respectively, while the filling end extending from compartment B is disposed above the rearwardly extending portions 86a and 61a of the separator fingers E6 and 61', respectively.

t is evident that upon downward movement of the shuttle box from the position shown in Figures 1 and 4, the lower surface of the rearwardly extending portion 65a of the separator finger 65 would assume a position between the two rearwardly extending portions 660, and 61a and would clamp the end extending from compartment B against the upper surface of the lay in the notch is as the shuttle from the compartment A is subsequently thrown across the lay above the rearwardly extending portion 65a of the separator finger 65. Since the finger a cannot move upwarolly beyond the point at which is engages the corresponding stop pin 1'5 it is evident that the horizontal portion 65a thereof should be accurate- 1y adjusted or positioned so as to reside in the; 65 cavity 19 when the shuttle box is in a lowermost position, that is, when the compartment A is disposed in alinement with the race plate II.

It is thus seen that the rearwardly extending portion 65a of the separator finger 65 will elevate the corresponding filling F-i so as to hold the filling F! from the top compartment A in elevated position while the filling F4 from another shuttle is pro ected from the compartment B to and fro across the lay to return to the compartment B. Thus, the filling F-l will be elevated out of the path of travel of the shuttle carrying the filling F4. Now, when the shuttle box is raised to the point where a shuttle is to be carried from and returned to the shuttle receiving compartment C, it is evident that the finger 66 will move a partial revolution in a clockwise direction in Figure 4 until it engages the stop pin 33 and will thus move upwardly with the shuttle box to elevate the filling F-Z to thereby move the same above the path of the shuttle to be discharged from the shuttle compartment C. Now, at this point, the rearwardly extending portion 65a will engage the lower surface of the reed cap l6 At this time, the transverse or rearwardly extending portion 66a of the separator finger fit will also occupy a position substantially the same as that in which the separator finger B5 is shown in Figure 4.

Now, presuming that the shuttle box is elevated to its highest position to cause the shuttle receiving compartment D- to be on the same level as the race plate ll, this would cause the finger 65 to be depressed by the lower edge of the reed cap and the finger 66 would be elevated against the reed cap while the finger 61 would also rise upwardly to lift the filling extending from the shuttle in compartment C since the finger would come in contact with the stop pin 86. All of the filling yarns from the shuttles in compartments A, B and C would thus be lifted above the lay and out of the path of travel of the shuttle from the compartment D.

For sake of clarity, in the drawings the filling yarns extending from the compartments C and D are omitted.

All of these operations are automatic as a result of the relative movement between the shuttle box and the lay of the loom and depend upon no pattern control means or other control apart from the loom as their only control is their corresponding torsion springs and the stop pins associated therewith which cause them to automatically assume the proper position depending upon which compartment of the shuttle box is being employed in the same horizontal level as the race plate I! on the lay It is evident that the filling yarns extending from any of the compartments which may be disposed below the level of the lay will be clamped against the lay by the fingers of the compar ment or compartments thereabove to also prevent these yarns from interfering with the operation of an active shuttle and to prevent the filling from the inactive shuttles from being pulled into the shed by the active shuttles.

It is thus seen that I have provided an im proved filling separator for multiple shuttle looms that is simple and economical to manufacture, that employs but a minimum of parts. that does not interfere with existing parts of the loom and does not need to be coupled to any moving parts of the loom for operation thereby. The separator fingers of the device are so mounted as to be readily adapted to any type of loom. The curved portions of the fingers prevent the filling from slipping off the fingers during rearward motion of the lay and the stops on the bracket 59 insure positive positioning of the rearwardly extending portions of the corresponding fingers at each boxed position.

In the drawings and specification there has been set forth a preferred embodiment of the invention and although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined in the claims.
