REED AND BACKSTAY ADJUSTMENT FOR LOOMS Filed June 11. 1951 r mjcntor' Gtbridge R.Ho\mes attorneys Patented Sept. 12, 1933- UNITED STATES PATE Q E Elbridge It. Holmes, Worcester, 'Mass.,' assig' nor to Crompton--& Knowles Loom-Works, Worces-' ter, Mass, a corporation of Massachusetts Application June 11,1931. Serial No. 543,625 20 Claims. (01. 139-489) This invention relates to improvements in mountings for loom reeds and it isthe general object of the invention to provide means whereby a reed may be given various setting transversel and longitudinally of the lay. j

It is another object ofmy present invention to provide the reed. with a mounting slidably connectedto the lay so that the reed as a whole may move parallel to the lay to accommodate slight variations in the direction of feed of the warp and cloth. This sliding connection'may preferably though not necessarilytake the form of ,a pivotal connectionbet-ween the reed and the lay,in which case the reed can move both transversely and longitudinally of the lay to accommodate various conditions arising in the operation of the loom.

Loom reeds are ordinarily carried in a fixed position with respect to the lay but their con-.

4 stant beating against the fell of the cloth wears the reed wires, necessitating a change of vertical position-in order to prevent cutting of the filling;

It is a further object of my invention toprovide improved means to vary the position of the reed relatively to the cloth line of the loom.

The cloth line-is determined to some extent by a-warp engaging rod, preferably of glass, and it is another object of my invention to be able to adjust this rod relativelyto the reed.

. It is a still further objectof my invention to provide an adjustable positioner for the lower rib of the reed to be located on the layby positioning elements, such as screws to determine the relation of the reed relatively to the lay.

It is-another object of my invention to provide means for holding the top ofthe reed adjustably against a surface which may be parallel to or extend at least longitudinally of the lay to permit vertical. adjustments of the reed. 7 With these andot'her; objects in view which will appear as the description proceeds, my invention resides in the combination and arrangement of .parts hereinafter describedand set forth in the claims. I

In the accompanying drawing, wherein aiconvenient embodiment of my inventionis set forth, 'Fig. 1 is avertical transverse section through a lay made according to my present invention,

Fig-. 2 is a front elevation of the structure shown in'Fig. 1 and showing the reed in one adjustedposition, r a i Fig. 3 is a diagrammatic view similar to apart of Fig. 1. on a reduced scale showing the reed in two adjusted positions vertically,

back of the loom and showing the reed in three different-positions transversely ofthe cloth, and

Fig. 5 is a detail horizontal section on line 55 of. Fig. 2. j

Reierring to the drawing, .1 havev shown a lay supported by lay swords one of which is indicated at 11 in Fig.2. The lay may be made of a Wooden beam or the like and has on the top thereof the customary race plate 12 of the shuttle. At each end of the lay is a lay. end 13 having an upwardly extending horn 14. 'Each of the latter supports afoot l5- of'a bearing 16' andthe foot is provided with" slots 17 through which extend bolts lfi'threaded into the arm 14. The bearingis therefore adjusted vertically to assume a pin rality'of positions withrespect to the raoe'plate and lay 12. j V

The bearing 16 supports a stud 20 which projects toward the center of the loom and has slidably and rotatably mounted thereon a -pivot element 21. The latter is connected by bolts 22 as shown in Fig. 2 to a handrail section 23 formed T-shape as shown in Fig. 1.. The top of this section supports a wooden hand hold 24, while the A retaining plate 26 has a horizontal foot2'l held against theweb by. screws 28, the lower end of the plate forcing the top rib 229 of the reed R against the section 25. By varying the position'of the rib 29 relatively to the parts 25 and 26 the reed can be raised or lowered'with respect to the hand rail and also the stud-20. A further vertical adjustment of the reed may be se-; cured by manipulating the nuts 18, the slots 17 permitting movement of the top structure as a whole relatively to the lay.

The rear upper edge ofthe lay is notched as at 30,. having verticaland horizontal walls Y31 and 32, respectively. Horizontal positioning screws 33 pass through the lay wood and project somewhat beyond the vertical wall 31, being held by rear and front nuts 34 and 3 5, respectively. A reed positioner 36 L-shape'in section has a' vertical web 37 which engages the positioning screws 33, while the horizontal part 38 .bears against the rib 40; being supported onat least two levers ,4? one of which is shown in 'Figs. 1 and 2. .Each of these levershas at the.

- is slotted and receives a tightening-orclamping lower end thereof a hub 48 which pivots around a stud 49 carried by a bracket 50. The latter extends upwardly and has slot 51 through which extend securing bolts 52. The latter are held by a depending support 53 secured to the under side of the lay. The support is provided-with an ear 54 which extends'substantially parallel to a similar ear 55 formed on the lever 47. A bolt 56 extends through the ears and has at the rear end thereof a head 57 bearing against the ear 55 under pressure of a compression spring 58' The backstay can be moved vertically'witlr respect to the lay by adjusting the bolts 52 and it will be seen that the ears 54 and 55 both'move together, sothat an adjustmentof the-bracket 50 moves the lever 47, ear 54, and the bolt 56,

K thereby preserving this part of the structure in proper relation for its various adjustedpositions. As shown in Fig. 3, the hand rail and reed are shown in relatively low position. in full lines and in adjusted raised position in dotted lines,'indicating-the'manner of changing the point at which the beat-up occurs on the reed. Fig. 4 shows the reed in the central position with respect to the loom in full lines, the dotted lines 60 at the right indicating that the reed as a whole can move to the right along the studs 20, while the dottedlines at the left indicate the opposite movement of the reed.

From the foregoing it will be seen that I have provided meansfor giving the reed a variety of movements bothvertically and'longitudinallyof the lay. It will also be seen that I have provided means for conveniently varying the vertical position of the glass rod 46 and also preserve the yielding connection between the lever 47 and the bracket 50. In this connection it is to be understood that spring 58 resists rearward movement of the backstay. Furthermore, the reed can move parallel to the lay against the sliding re-,-

sistance of spring 58. I
