WARP STOP MOTION FOR LOOMS.

Application filed October 4, 1921.

To all whom it may concern:

Be it known that I, EDWARD S. STIMPSON, a citizen of the United States, residing at Hopedale, in the county of Worcester and State of Massachusetts, have invented an Improvement in Warp Stop Motions for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to warp stop motions for looms, whereby upon the occurrence of a warp fault such, for instance, as breakage or undue slackness of a warp thread, the loom is stopped.

It is an object of the present invention to provide a warp stop motion or mechanism which shall be simple in construction, efl'ective in operation in response to a warp fault, and wherein the parts are so organized and combined that anumber of advantages, as hereinafter described, may be secured.

It is desirable at times to run the loom without causing the stoppage thereof due to a warp fault. These occasions arise, for instance, when a new warp is placed in the loom. Under this condition it is desirable to run the loom for a time to condition the warp and bring the warp threads into uniform tension and arrangement for the weaving operation. The occasion for running the loom without stopping due to a warp fault, may also arise where there has been a smash or other condition that disturbs the general arrangement and tension of the warp threads. An important feature of the present invention, therefore, consists in a warp stop motion wherein the feeler may be moved at will from operative position with respect to the drop wires, so that without disturbing other portions of the warp stop motion, the loom may continue to run even though some of the warp threads are too slack or become broken.

Where the warp stop motion proper is placed between the shedding mechanism or heddles and the rear of the loom, the character and construction of the warp stop motion will determine to a large extent the size of the warp beam, or the amount of warp Specification of Letters Yatent.

permissible to be wound upon the beam. Another important feature of the invention, therefore, consists of a warp stop motion which is compact and which shall occupy a minimum amount of space fore and aft of the loom, and wherein the construction is such that it will not interfere with or materially limit the size of the warp beam or the amount of warp wound upon the beam.

The above and other novel features and new combination of parts will best be made clear from the following description in connection with the accompanying drawings, which show one good, practical form of means for carrying the various features of the invention into practical effect.

This application is a continuation in part of the copending application of Edward S. Stimpson, Serial No. 474,368. filed June 2, 1921. p

Fig. 6 is an enlarged detail perspective view of a portion of the warp stop motion proper, and the adjustable warp support.

As indicated in Fig. .1, the warp stop motion proper is located between the shedding mechanism or heddles and. the rear of the loom, and is associated with the mechanism actuated by the lay when the feeler is arrested in its detecting movement by a'drop wire, to thereby knock-0E the shipper and efiect loom stoppage. The illustratedform v of the .mechanism between the warp stop motion proper and the shipper constitutes a good, practical trainv of mechanism for" effecting the desired purpose, but it is to be understood that the invention is not re stricted thereto, but that thewarp stop motion proper may be associated with any dcsirable train of mechanism which w1ll serve to bring the loom to rest when a detecting.

movementof the feeler is stopped by a drop wire.

The term drop wire is herein/usedin its broad sense to designate the elements which are normally supported by the warp threads during weaving. The drop wires shown are formed of or stamped out of sheet metal.

' The loom frame 1 may be of usual con-- struction provided with asuitable support.

at the rear portion thereof forthe warp beam 2 on which the warp threads are wound. Pivotallymounted at 3 is the shipper 4 which, when the loom is runn'in may to an arm 11 pivotally supported at 12 by a bracket 13, Fig. 2, secured to the loom frame. Mounted for rocking movement on the arm 11 is the dog 14, Fig. 2, having a pin 15 which extends into the slot 16 of a controller 17 secured to the rocker 18 mounted in a hearing at the upper portion of the bracket 13. The lay 19 has connected thereto the bunter 20, preferably adjustable, as by the slot and bolt connection 21, Fig. 2, the

construction being such that should the end of the dog 14 be in position for engagement with the hunter 20! as the lay moves back, the rocker arm 11 will be moved backwardly and thereby exert a pull upon the link 9 to knock-off the shipper and stop'the loom. The mechanism so far described is or may be of usual construction, such; for instance, as shown' and described in the patent to G. B. Ambler, No. 885,130, dated April 21, 1908, but so far as the novel features of .the present invention are concerned, other forms of transmitting mechanism may be rename employed between the warp stop motionproper and the loom stopping mechanism for effecting loom stoppage when the feeler is arrested in its detecting movement by a drop .wire.

Extending from the rocker 18 is an arm 22, which is connected at 23 toa link 24, the upper portion of which is jointed at 25 to a rocker arm 26 secured to and extending from the rock shaft 27. The rock shaft 27 has secured thereto an arm 28 to which is connected the link- 29 which extends downota-lly connected at 30 to a dam follower.- 31

pivotally supported at 32. Adjustably supported upon the rocker arm 26 is the weight 33 which serves to hold the end of the cam follower 31 against the cam 34, Fig. 1, which is conveniently secured to or operatively connected with the lower or cam shaft35. From the mechanism thus far described it will be apparent that as. the cam moved out of the path of the hunter 20 as the lay moves back.

Secured to each side of the loom frame is a bracket or support 36, Figs. 3 and 4, having a slot 37. to which is adjustably connected the side brackets 38 which, in the present instance, constitute the support for the warp stop motion proper. The side brackets 38 have lateral extensions 39 slotted are the warp supports 43, the ends of which may be received in socket members 44 extending inwardly from each of the brackets 38, Figs. 3 and 4. In the present instance,

four warp supports 43 are shown, but obviously the number of such supports may be Varied to suit conditions of use. The warp threads a pass from the warp beam 2 over the warp supports 43 to the shedding-mechanism or heddles 45 which may be of usual construction and operated in 5 well-known manner to form the shed. From the heddles 45 the warp threads pass through the reed 46 to the fell of the cloth at 47, from which point the cloth is led forwardly to any uslial form of takeup.

Supported above the plane of the warp threads are the drop wire guides 48.- In the present instance the drop wire guides 48 are supported by the side brackets 38, each of which has upwardly-extending lugs 49 corwire guides, four being shown in the present instance, but obviously any desired number may be employed. The drop wire guides 48 are detachably held to the side brackets 38 by clips 50, Fig. 4, each having a slot 51,

Fig. 4, through which passes the securing bolt or screw 52. Adjacent the end portion of each of the drop wire guides 48 the clips 50 have an upstanding portion 53 and a flange 54 which overlies the top of the drop wire guides, the construction being such thatguides 48 is a series of drop wires 55 which are normally supported by the warp threads during weaving. The drop wires may be variously formed, but in the present instance of the invention each drop wire is provided with a slot 56 through which is passed a drop wire guide for directing movement of the drop wire when it is released by a broken or too slack warp thread. Each of the drop wires has an enlarged portion 57 and as shown, the rear portions of the drop wires of the several rows all face-in the same direction. As shown, each of the drop wires has the lower leg portion 58, the upper end wall of which rests upon a warp thread and serves to maintain the drop wire in its raised position during weaving. In certain aspects of the invention the particular form of drop wire is immaterial, but the construction shown, which is known as the hairpin drop wire, is found to be preferable for certain purposes.

Associated with the drop wires is afeeler which is given a detecting movement and which, when arrested by one of the drop wires, effects loom stoppage. As before mentioned, it is desirable at times to run the loom without stopping due to a fault in the warp, and for this, urpose the present invention provides a feeler mechanism which may be moved from operative relation with the drop, wires at will, so that even though a warp thread should break or one or more of such threads become too slack for good weaving purposes, the loom will continue to run so long as the feeler mechanism is not in operative relation with the drop wires. In carrying this feature of the invention into practical effect, the feeler for a row of drop wires is supported above the plane of thewarp threads and for detecting movement toward and from the drop wires. In order that it may be readily removed from operative relation with the drop wires without disorganizing the warp stop motion, the feeler is connected with its actuating mecha nism in a manner to ermit the feeler to be moved in a direction eightwise of the drop wires out of operative relationtherewith.

In the particular construction shown for carrying out this feature of the invention, the supporting brackets 38'are each provided with a guiding support 59 which may be conveniently formed as part of or be connected to the brackets 38. In the present instance the guiding supports 59 are cast integral with the side brackets and afford a support on which the side members 60 of a feeler carrier may rest. Extending between and secured to the side members 60 of the feeler carrier are the feelers 61, corresponding in number with the number of rows of drop wires. The side members 60 of the feeler carrier are provided with lug portions 62, Figs. 3 and 4, to which are'secured the feelers 61 by means such as the securing bolts and nuts63, the construction being such that they may be readily secured to or removed from the side members of the feeler carrier. Each side member 60 of the feeler carrier has an extending portion 64 which may be connected to the 'feeler actuator, presently to be described, by means of a pin 65 extending laterally from each of the extending portions 64, whereby the feeler car rier may be given a reciprocating movement on its guiding supports 59.

Extendin from the rock shaft 27 is the arm 66 having a bifurcated upper end portion 67 which receives the pin 65 extending from the feeler carrier, the construction being such that u )011 rocking movement of the rock shaft 27, t e feeler carrier and perforce the feelers carried thereby, will be given a reciprocating movement, and the feeler carrier and feelers may be readily removed at will from operative relation with the drop wires by a movement of the feeler carrier and feelers in a direction heightwise of the drop wires.

As a preferable form of construction, the side members 60 of the feeler carrier have end bearing portions 68 which rest upon the guiding supports 59, while the other end portion of the side members of the feeler carrier may be supported by the bifurcated end 67 of the feeler actuator. From this construction it will be apparent that the weight of the feeler carrier and feelers is supported at one end. by the guiding supports 59, and at the other end by the bifurcated end 67 of the feeler actuator.

When the feeler and feeler carrier are removed from operative relation with the drop Wires, which is effected manually by the loom attendant, it is desirable that the feeler carrier and the feelers be supported within convenient reach of the attend-ant so that they may be replaced after the warp threads have become conditioned properly for weaving purposes. As a convenient means to this end, the arch 69 of the loom,

-Fig. -3, may be provided with supporting rests 70 having end portions 71 for receiving lessening the spaceoccupied by the feeler mechanism proper in proximity to the warp beam, and permitting a ready movement of the feelers from their operative relation with the drop wires either to permit theloom to be run without stopping, due to'a warp fault, or to permit the ready removal of the drop wires, drop wire guides and warp threads in removing and placing a new warp.

The feelers 61 are supported above the plane of the warp threads in an inclined position, thereby enabling the feelers to be formed of sufficiently heavy metal or stock to withstand the checking action of the drop wires without bending; and such inclined position of the feelers economizes the space occupied by the feeler mechanism fore and aft of the loom and prevents the accumu lation oflint upon the feelers, which might otherwise interfere with the delicate operation of the mechanism. The detecting portion 72 of each feeler which engages a drop wire when it is released by a broken or too slack warp thread, is preferably beveled with respect to the main body of the feeler, as indicated in Fig. 4, to present a substantially vertical wall to act upon the vertical edge of the drop wire. The inclined relation of the feelers with respect to the lengthwise dimension of the drop wires is conveniently secured by forming the supporting face 73 of the lugs 62 inclined, as indicated in'Fig. 4.

It is sometimes desirable to brace the feeler or feelers between the ends thereof in order to impart stability; especially is this the case where the feeler is employed in what is known as a Wide loom. In such cases the side members 60 of the feeler carrier may be further braced and secured together by an angle bar 73 which may conveniently be formed as part of one of the feelers, as indicated in Fig. 3. Secured to the angle bar 73 is a lug 74, Fig. 3, to which is secured a feeler brace 75, the lower edge portion of which is notched as at 76, Fig. 3, to receive the upper edge portion of each of the feelers 61. The number of braces 75 may be varied.

guide braces are mounted for transverse adjustment upon the brace-supporting rod 77, Fig. 3, which may be conveniently supported in bearings 78 provided'in the side brackets 38, and if desired, the supporting rod may be secured in position by a set screw 79, at each end.

Mounted for transverse adjustment on the supporting rod 77 are the collars 80, of which there may be one or more, three being shown in the present instance of the invention. These collars may be secured in adjusted position on the rod 77 by appropriate securing means such as theset screws 81. Extending from each of the collars 80 is a lug 82 having a bearing to receive the stem 83- of the drop wire guide brace, which is preferably formed circular in cross section for ready swinging adjustment in the bearing 82. Each of the collars 80 has a set screw 84, whereby the associated stem 83 may be secured in adjusted lateral swinging position.

Mounted upon each of the stems 83 is a drop wire guide brace 85, which has a series of notches 86 corresponding to the number and for the reception of the drop wire guides 48. The slots 86 are of suflicient size with relation to the dimensions of the drop wire guides, to permit the brace or braces 85 to be adjusted laterally at one end to correspond to the convergence of the warp threads toward the front of the-loom, as indicated in Fig. 3. In. the present instance of the invention, the braces 85 are connected to their supporting stems 83 by the heads 87 and clamping bolts 88, but these details may be varied within the true scope of the invention.

In weaving some kinds of fabrics, it is desirable to vary the position of the warp supports, for instance, as in adapting the warp stop motion to a loom for weaving Marquisette or crossswoven fabrics. To this end, as indicated in Figs. 5 and (3, the warp supports 43 may be carried in sockets 89 formed in an adjustable member 90 which will be made separately from the side brat-la ets 91, similar in all other respects, how- GV6I',ftO the side brackets 38 already de-' scribed. The adjustable members 90, one at each side of the loom, have lug portions 92 which extend through the openings 93 formed in the associated bracket 91, as indicated in Fig. 6; and between the lug 92 and 13'.

the outstanding portion of the bracket 91 is interposed an adjusting screw 94, the construction being such that when the members 90 are free for adjusting movement, they may be either raised or lowered in accord- 'ance with the character of the fabric being woven, by manipulation of the adjusting screw 94.

The members 90 which sustain the warp supports, may be clamped in their adjusted position by means of a clamping bolt 95, Fig. 6, one of which passes through each of the side brackets 91 and enters a slot 96 formed in the associated member 90.

Should the rock-shaft. 27, which constitutes part of the actuator for the feeler, be mountedon the adjustable side members 90 as indicated in Figs. 5 and 6, the present invention contemplates that the connection between the feeler and the actuator shall be such that upon adjustment of the warp supports, the same amplitude of feeler movement ma be maintained. To this end the pin 65wh1ch engages the bifurcated end 67 of the arm 66 which projects from the rock shaft 27, is carried by a plate 97, Figs. 5 and 6, which is adjustably secured to the projection 64 extending from the side members of the'feeler carrier. In the present instance the plate 97 carries the pin 65 and 1 is provided with a slot98, Fig. 5, through space in the loom; but in certain aspects of which passes the securing bolt 99 which adjustably secures the plate 97 to the projection 64. The construction is such that when the warp supports are adjusted with their side members 90 u or down, the plate 97 may be correspondlngly adjusted to maintain the same amplitude of movement of the feeler carrier and feelers, which are reciprocated by the rocking arm 66.

In the construction shown, the feelers are mounted or supported in an inclined position relative to the lengthwise dimension of the drop wires, and such construction is of advantage in economizing the fore and aft the invention, the feelers may be otherwise related to the drop wires, and the drop wires themselveswhile shown as of the fhalr-pin type, may be of different construction.

The construction shown and described constitutes a good, practical form of the present invention; is simple and efficient in operation; and by combining the parts in the relation described with the feelers above the plane of the warp threads, not only does the warp stop motion not materially interfere with the size of warp beam or the amount of warp wound on the beam, but the feelers'themselves are rendered readily accessible and removable from operative relation with the'drop wires by the loom attendant when it is desired to run the loom without stopping, due to a warp fault or when a warp is to be removed or placed in the loom. The reciprocating movement give; to the feeler o'r feelers toward and from th\ drop wires in a path above the warp threads, and by an actuator,'preferably at each side of the loom, enables the feeler mechanism including the feelers and feeler carrier, to be made of suflicient rigidity to withstand the arresting action of thedrop wire without flexing or bending the feeler;- a'condition which may be further insured in case the feelers are supported in the inclined positiondescribed. An important feature contributing to the advantages flowing from the present invention, is the fact that the feelers are not only supported in position above the plane of the warp threads, but are mounted in the side members of a feeler carrier, which is supported and operated for ready removal as a whole from operative position. In the preferred construction, the side'members of the feeler carrier include between them the entire series of drop wires and drop wire guides, so that no obstruction may be offered to the removal of the feeler carrier when it is desired to run the loom without stopping, due to a warp fault or to change the warp in the loom.
