E. A. sANToN` 2,346,61S TAKE-.UP FOR LoMs Filed May l. 1943 Patented Apr. 11, 1944 TAKE-UP. FOR LOOMS Elliot A. Santon, Worcester, Mass., assigner to Crompton & Knowles Loom Works, Worcester, Mass., a corporation of Massachusetts Application May 1, 1943, Serial No. 485,323

(Cl. 13d-304) 1d) Claims.

This invention relates to improvements iin take-ups for looms and it is the general object of the invention to provide a take-up drive which can be operated either automatically by the loom or manually.

The cloth in a loom is led from the weaving point to a roughened take-up roll which is driven during loom operation to pull the cloth forwardly. A train of gears is connected to the take-up roll and is driven by some part of the loom at the proper rate to advance the cloth as it is woven. During normal weaving operations the take-up is driven forwardly but should a inispick occur necessitating removal of any picks of weft from the fabric the take-up roll is reversed so that the fell of the cloth can be moved rearwardly. Y

It has been proposed heretofore to operate the take-up roll by a worm wheel meshing with a' worm driven by power derived from some part of the loom, such as the upright shaft of the Knowles head customarily used on worsted looms. 'Ihe worm has formerly been connected to a forwardly extending take-up shaft carrying a hand wheel by which the worm and its worm wheel could be manually reversed. It is an im` portant object of my present invention to mount the hand wheel on a sleeve carrying the worm and provide the hand wheel with a handle normally in meshing or driving relation with a driving wheel on the forward end of the take-up shaft which passes through the sleeve. The handle is constructed in such a manner as to reduce wear of itself and the part of the hand wheel which it engages.

It is another object of my present invention to provide the handle with means for pivotally connecting one end of it to the wheel and constructing the other end of the handle so that it will engage a part of the wheel and assist in holding the handle substantially fixed with respect to the hand wheel to provide an improved driving connection with the aforesaid driving wheel.l

It is still a further object of my invention to provide the hand wheel with two similar pockets either of which can receive the pivoted end of the handle while the other receives the outer end of the handle. This feature of my invention permits reversal of the handle with respect to the pockets when objectionable wear has developed. No matter which pocket provides the pivotal support for the handle however the opposite pocket will receive the outer end of the handle to assist tween the shaft and the worm.

- It is a more particular object of my present invention to provide a loom take-up hand wheel having diametrically opposite pockets the lower part of each of which can receive the pivoted end of the handle while the upper part of each pocket can each receive and have engagement with the outer end of the handle. By this arrangement any wear which develops in one of the pockets adjacent the pivoted end of the handle will lie below that part of the pocket which engages the outer end of the handle when the latter is reversed. The result of this construction is to cause the opposite ends of the handle to engage different parts of the pockets so that upon reversal of the handle its ends will engage unworn surfaces of the pockets.

Withv these and other objects in view 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 convenient embodiment of my invention is set forth,

Fig. 1 is a side elevation of part of a loom having my invention applied to the take-up thereof,

Fig. 2 is an enlarged front elevation in the direction of arrow 2, Fig. 1, `showing the hand wheel and its handle in normal driving position,

Fig. 3 is a section on line 3-3 of Fig. 2 showing the handle in force transmitting position in full lines and in dotted lines for manual turning of the hand wheel and its worm, and

Fig. 4 is a transverse section on line 4 4 of Fig. 3.

Referring particularly to Fig. 1, I have shown a loom frame I0 having a pattern mechanism K driven by an upright shaft II and the usual gearing indicated generally at I 2 for the shaft. This gearing includes a sleeve I3 which is normally down but which can `be raised in the usual manner by mechanism I A. Extending forward` ly from the mechanism I2 is a take-up driving shaft I5 journaled at I6 with respect to the loom frame and having the forward end thereof surrounded by a sleeve Il. A worm I8 on the sleeve meshes with a worm wheel I9 rotatable about an axis 20 and geared by mechanism not shown to the take-up roll and its train of gearing. A hand wheel 2I is provided for turning the sleeve Il and worm I8.

The matter thus far described is of usual construction and may if desired take the form shown in the following prior patents: McGuiness t 737,002; Ryon 886,871, and 1,552,651.

In carrying' my invention into effect, I provide an improved driving connection between a takeup shaft I and the sleeve I'I, this driving connection comprising a handle H mounted pivotally on the wheel 2| and movable into and out of driving connection with the shaft I'I. Referring more particularly to Figs. 2 and 3, the wheel 2| has a continuousv rim 25 and a hub 26 held to the sleeve I'| by a set screw 2.1 and connected. to the rim 2| by two spokes 23. Two other spokes 30 and 3| formed in accordance with my present invention also connect the hub to the rim.

Spoke 30 has two

spaced walls

32 and 33 between which extends a pocket or slot 34 which is substantially radial with respect to the axis of the wheel 2|. A pivot pin 35 extendsv through the

walls

32 and 33 and across the slot 34 at a point displaced rearwardly from the plane of rim 2|, the front of the loom being at the right of Fig. l. In similar manner the spoke 3| has spaced walls l0 and 4I separated by a. pocket. or s101142 4across which extends a, pivot pin #i3 held by the adjacent. walls. The two spokes: 3i] and- 3| and the pivot pins are substantially the same and: the slots 3.4: and 42 are diametrically opposite.

The take-up shaft I5 has keyed thereto asat 4,1: a driving or clutch. wheel I8 having several peripheral notches. 49. each one: of which. isy pro,- portioned to` receive a driving or clutching lug 55.- on` the handle H. When the parts are inv the positionr shown in full lines in. Fig. 3, the lug will be in onev of the notches and as the shaft I5' turns the driving wheel 48 will turn` the lugV 5d,- and handle, around the. shaft axis.

The handle is` formed more particularly as shown in Figs.A 2 and 3 and comprises; a. body 55 shaped to afford a hand hold. One end of the handle is flattened` as at 55 and is of such a width as to ft snugly into either of the pockets or

slots

34 and 42. This end of the handlieis provided with aA bore 5l to receive one or the other oi the

pivot pins

35 and 43. Flattened sur.- faces 543 and 59 angularly disposed as shown in Fig. 3` are adapted for engagement with the head 50 of a spring plunger mounted in the rearpart; of the spokes 3l) and 3| at the bottoms ofA the pockets or slots 3.4 nad 42.. It is to be under stood that the spring plungers are similar` and that one is provided for each of the

slots

34 and 42;. Underl normal conditions onel of the spring plungers will engage the surface 59 to hold the. handle I-I inr idle position.- preferably within the outline of the hand wheel 2 I, but the. handle can be moved to the dotted line position in Fig. 3 against the. action of the associated spring plunger and the head of the latter will thenV hold the handle in proper position for manualturing of the wheel.,

That end 55 of the handle H which is opposite the flattened end is of such size as, to t snugly into one or the .other of the slots 3.4 or 42.. It. will be seen from Fig. S that the reduced end 55 engages those parts of the adjacent walls which are forward of the parts ofthe; wall which can bei engaged by the flattened part 55` of the handle.

Assuming that the parts are in the position shown in Fig. 2, the rear part of slot 3.4 will ree ceive the flattened'end while the front parti of slot 42 will engage the end 65 of the handle. The handle is therefore held firmly in the two pockets of the hand wheel, extending across its diameter and firmly placing the lug 5U in one of the driving notches 49. The driving force ofthe shaft I5 is therefore transmitted from the driving wheel 49, through the lug 50 and the handle H, to the wheel 2|, both ends of the handle assisting in this transmission of force. The handle end 65 reduces vibration of the flat end 56 of the handle to a minimum, but after long continued use the parts of the

walls

32 and 33 which engage the, handle develop Wear. When this occurs the

pins

35 and 43 are removed and the flat end 56 of the lever taken out of slot 34 and inserted into slot 42, after which the pin 43 is replaced to establish pivotal connection between the handle and walls and 4|.

Any wearing of the walls 4|) and 4I in the iirst setting of the handle due to movement of the handle end 65 will occur at the front end of pocket 42 only, and the flattened end 56 of the handle in its new position will fit into the rear part of the slot 42. which was not previously worn by the handle end 65. In like manner, the end 65 will be located in the front. end of slot 34, which did not have previous engagement with the flat end 56 of the handle. The handle in, its, newv setting therefore engages surfaces which it did not. en gage in its previous setting. The lug will' be able to t into one or another: of the notches 49 when the handle is thus; reversed.

From the foregoing it willbe seen that I have provided an improved hand wheel and handle. serving as a drive between the shaft I5 and the. worm I8 so constructed that the handle I-I when in normal position engages opposite sides of the wheel to drive the latter uniformly and prevent jarring and objectionable motion between the pocket walls andthe ends of the handle. It will also be seen that the handle is reversible due to the construction and proportions of its ends and that the lug 5! will have driving relation with respect tothe drive wheel 48 when the handle is in either of its positions. be noted that the flattened endengages the; rear parts only of the

pockets

34 and 42 whereas. the handle end engages the forward parts only of said pockets', hence the wear produced by one end of the handle inthe pocket does notI interfere with the proper fit of the other endv ofthe handle` when the latter is reversed.

Havingv thus described my invention it will be. seen that changes and modiiicati'ons may be made therein, by those skilled in the artwithout departing from the spirit and scope of the invention and I do not wish to be limited to' the details. herein disclosed, but what Iclaim is:
