"Application Math 27, 1950, Serial'No; name I 2- Claims. (01. 139-194) Our invention relates to improvements in looms and is a device for engaging the filling between the selvage of the fabric and the shuttle, to move the filling out of the path of travel of the shuttle, upon the next pick. It is well known that looms frequently do not operate properly, because a slack or loop in the filling occurs, between the selvage and the shuttle. This loop may be at the bottom of the shuttle and the shuttle will pass over the loop 'upon the next pick and sever the filling. The loop may occur near the top of the shuttle, and will be engaged by the shuttle and the back side of the shuttle box, and the filling will be severed. As far as we are aware no means has been'provided for overcoming this difficulty. We provide means to engage with the filling between the selvage and the shuttle, and move the filling out of the path of travel of the shuttle, prior to the next pick. It has been found that trouble of this kind usually occurs near the left shuttle box. We contemplate arranging our device near the left shuttle box and may also arrange another identical device near the right shuttle box.

In the accompanying drawings forming a part of this application and in which like numerals are employed to designate like parts throughout the same,

Figure l is a fragmentary plan view of a loom, partly diagrammatic, showing our attachment applied thereto with the lay moved rearwardly toward the shed, and the filling moved out of the path of travel of the shuttle,

Figure 2 is a similar view, showing the lay in the forward dead center position and the filling engaging element pressing the filling against the rear wall of the shuttle box,

Figure 3 is a vertical section taken on line 3-3 of Figure 1, showing our filling removing element applied to the rocker arm of the filling feeler device,

Figure 4 is a perspective view of the filling removing element and rocker arm, the fibrous element being removed for the sake of illustration, and,

Figure 5- is a side elevation of a washer employed in holding the filling removing element in place.

In the drawings the numeral 19 designates a loom side having a breast beam ll secured to its front end. The left side of the loom isshown. The numeral l2 designates the lay, provided at each end with a shuttle box 13, having a rear wall 14. Mounted upon the lay is the reed l5, and a grate I6 is mounted upon the lay between the shuttle box and the reed. I 1

The numeral I! designates a filling detector device comprising generally a stationary housing l8, mounted upon the breast beam I I. This detector device comprises a slide I9, mounted'within the stationary housing l8. A vertically swinging head 20 is pivotally mounted upon the rear end of the slide I9 and carriesthev filling fork 2|.

A loop 22 is carried by the head 20 and is adapted of any well known or preferred-type such as is shown in Patent 912,415.

The numeral 28'designates a shuttle having an eye 29 upon its front side and 30 is a filling ex- ;einding' from this eye tothe selvage of the fabric ur filling removing implement com'prisesan' upstanding resilient arm 32, provided'at its upper end with a horizontal extension 33, carrying/an upstanding finger 34. The numeral 35'design'ates the-filling engaging element; which isformed of a section of wool carried by the original hide 36. This hide is folded upon itself to form a loop' and the sides of the loop are secured together by glue, and the finger 34 is inserted'with'in the loop and 'is also glued to the loop. The wool fibres '3"! are combed so that its'strands are arranged generally parallel. We have found that; wool produces satisfactory results although we contemplateu'sing other pile fabric or stran'di devices,ksuch-as a fine brush- :It'is thus seen thatithefibrous filling engaging element 35 .is' resilient and com.-

pressible and its strands are generally parallel, andthefilling is adapted to be imbedded between or within the strands of the element 35 and will stick to th element 35, sufiiciently to be moved out of the path of travel of the shuttler-when the element 35 moves from'the lay l2. The arm 32 is mounted near the armsection 25 and extends longitudinally thereof. The arm sections 25 and 26 are interlocked and connected by a bolt38, having a nut 39., The'nut39is removed and a washer 40 is applied to the nut and the lower'end of the arm 32 'is arranged between this Washer and the upper end of the arm section 26. The washer 40 is provided upon shuttle and the selvage of the fabric.

its inner face with a rib ll having the same thickness as the arm 32. The nut 39 is screwed up and the arm 32 clamped to the arm section 26 and removes therewith.

The construction of the loom and its parts are conventional, and our invention is the filling removing implement applied as shown and described. When the filling fork2l moves into close relation to the grate l6, and should the filling be broken, the filling fork will remain vertical, and.

the loop 22 will interlock with the hook 23, and when the hook is moved forwardly, prior to the next pick of the shuttle, the loop 22' and slide I 9 are moved forwardly and the operation of the loom is stopped, as is disclosed in said Patent 912,415. The operation of the deviceis asfollows: When the shuttle 28 has moved upon its last pick into the shuttle box I3 to the left, the lay is in the forward dead center position and the rocker arm 24 has been swung forwardly toward the lay, Figure 2, so that the filling fork 2| will engage withthefilling 30, extending from the shuttle 28 across the grate 26 to the-selvage of the fabric, if

the filling is not broken. The arm 32 moves with the rocker arm 24, and when the lay is in the front dead center position, the arm 32 is in the rearmost-position, and the fibrous element 35 will engage with the filling 30 between the eye of the The filling engaging element 35 will press the filling 30 against the rear wall H of the shuttle box. While the element 35 is pressing the filling against the rear-"wall I4 of the shuttle box, the filling is moved "longitudinally slightly by the action of the fork and grate I6. .This will produce a slight pull upon the filling and cause the filling to be imbedded within or between. the strands of the wool element 35. The face of the element 35 which contacts with the filling is horizontally elongated and substantially fiat, for affording a large area of contact between the element and the filling. After this action, the lay moves rearwardly toward theished, and the arm 32 moves forwardly from the lay. The filling 30 between the shuttle 28 and salvage is moved forwardly out of the path of travel of the shuttle, Figure 1. Upon the next pick, the. shuttle is thrown to right but the filling I9 is out of the path of travel of the shuttle, and the severing of the filling by the shuttle elimmated. The pick occurs when the lay is at top center.

It is to be'understood that the form of our invention herewith shown and described -is to be taken as a preferred example of the same and movable toward and from the grate, a fillingfork device for coaction with the grate and connected with the slide 'to move it, a rocker arm, detachable means for connecting the rocker arm with the filling fork device, and filling shifting means mounted upon the rocker arm for movement therewith and including a head arranged between the shuttle box and the grate and positioned to press the filling against the rear side of the shuttle box, said head embodying an elongated base having a face extending at substantially a right angle to the plane of movement of the rocker arm and long strands carried by the base and arranged generally parallel to each other and positioned generally at a right angle to the base, said strands having their outer ends free, the arrangement being such that the filling is embedded between the free ends of the long strands when such long strands press the filling against the rear side of the. shuttle box. and the filling is moved longitudinally with relation to the head due to the action of the filling fork device and grate upon the filling, the filling embedded between the free ends of the long strands moving with the head when the head is shifted from the rear side of the shuttle box so that the head moves the filling out of the path of travel of the shuttle before the next pick.

2. In a loom, a lay, a shuttle box mounted upon thelay, a grate mounted upon the lay between theshuttle box and fabric, a guide mounted upon the loom frame, a slide mounted upon the guide and movable toward and'from'the grate, a filling fork device for coaction with the grate and connected with the slide to move it, a rocker arm, 'detachable means for connecting the rocker arm with the filling fork device, and filling shifting means including a head arranged between the shuttle box and the grate and positioned to press the filling against the rear side of the shuttle box,

said head being formed of natural wool and including a section of hide forming a base having a face extending at substantially a right angle to the plane of movement of the rocker arm and long combed 'wool strands carried by the section of hide and arranged generally parallel with relationto each other and positioned generally at a rightangle to said base,said wool strands having their outer ends free, and a resilient arm mounted upon the rocker arm and carrying the head to press the wool strands against the filling and rear side of the shuttle box, the arrangement being such that the filling is embedded between the free ends of the wool strands when such wool strands press the filling against the rear side of the shuttle box and the filling is moved longitudinally with relation to the head due to the action of the filling fork device and grate upon the filling, the filling moving with the head from the rear side of the shuttle box and out of the path of travel of the shuttle before the next pick.
