g FFCE ROBERT E. WALLISER, OF CHICAGO, ILLINOIS COMBINED POWER AND HAND LOOM This invention relates to a combined power and hand loom designed for producing woven fabric or any figure goods7 and has for its object the provision of a machine of this character which will automatically stop at a certain predetermined point in the weaving of the pattern to permit of interweaving threads or cord into the pattern by hand.

A further object is the provision of a mala chine of this type employing a dobby loom whereby the machine will come to rest whenv the shuttle is at a particular position in its travel to permit the intermittent hand weaving operation, and thus maintain a uniform pattern. An additional object resides in providing` mechanism as an improvement to the type of loom employing a jacquard, deb-by; cam or equivalent pattern mechanism by means of which the pattern chain or form usually employed serves to actuate mechanism for intermittently halting operation of the shuttle mechanism and immediately following to actuate the stopping mechanism for the entire machine.

As a general object, the machine of the present invention makes possible the fabrication of textiles almost entirely automatically that formerly were required to be made entirely on a hand loom.

:il: Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be best understood by "f reference to the accompanying drawings forming a part of this specification, and inl to arm 34 of the clutch proper lor the purwhich:

F ig. 14 is a view of a typical woven fabric produced bythe machine of the present in vention at a stage when a hand operation is aboutV to be performed.

As illustrated in the drawings,` the preferred embodiment of the machine comprises a 'frame 2O upon which is mounted bearing block 21 for supporting a continuously rotating drive shaft 22. Belt 23 travels over pulley 24 (see Fig. 11) which is loosely mounted upon shaft25 and'supported by spokes 26. Within pulley 24 is a friction drum clutch 27 covered with the usual clutch lining`28 and split at one side to allow for engagement and disengagement with pulley 24. Clutch 27 is keyed to the shaft 25 and is supported by arms 29 and 30, upon the latterof which is pivotally mounted a clutch shoe 31. Secured kto the shaft which carries shoe 31 is an arm 32 connected by spring 33 pose of normally maintaining shoe 31 in poof the clutch.

37 lwhich meshes with bevel gear 38 for drivingv shaft 39 disposed at right angles to the main shaft 25. Batten 40 for packing the woven fabric has laterally extending members 41, 42 adapted to slide in guides 43 and 44, respectively, secured to the frame of the machine. Members 41 and 42 extend rear wardly of the machine as shown in Fig. 1 and at their extremities are provided with laterally projecting pins and 46. Upon pins 45 and 46, respectively, are pivoted links 47 and 48 which in turn are pivotally connected to arms 49 and 50 secured to rock shaft 5l journalled in the frame of the machine at 52 and rock shaft 51 is actuated through a depending arm 53 secured thereto, which in turn is pivoted to link 54 (see Fig. 9). Link 54 is given oscillatory motion by means of a roller 55 operating within cam groove 56 upon cam wheel 57, keyed upon shaft 39, and link 54 is slotted at 58 to straddle shaft 39 in its reciprocating motion.

The finished material travels over a drum 59 which is driven at a relatively slow rate of speed, and is secured to shaft 60 journalled upon the frame of the machine at 61, (see Figs. 1 and 2). At one end of shaft 60 is a worm wheel 62 which is driven by worm pinion 63 mounted upon shaft 64 in bearings 65 and 66 upon the side of the machine. At the opposite end of shaft 64 is mounted a ratchet wheel 67 and oscillating arm 68 is pivotally mounted upon shaft 64 and carries spring pressed. pawl 69 by which ratchet wheel 67 is actuated. Locking pawl 70 is mounted upon a frame of the machine opposite pawl 69 for the purpose of preventing` backward rotation of ratchet wheel 67. Arm 68 is normally pulled toward the left as shown in Fifr. 7 by spring 71 connected to the frame of the machine, and is also connected by a transversely extending link 72 to a link 73 pivotally mounted to the frame of the machine at 74. It will be noted that link 73 and arm 68 are slotted at their lowermost ends to permit of adjusting the relative rotary speed of drum 59, and oscillatory motion is given to link 78 by means of a cam 75 secured to the shaft 25, and which bears against roller 76 mount-ed upon link 7 For convenience in the delivery of the woven fabric 77, a friction roller 78 is adapted to bear against drum 59 and the finished material is thread-ed therebetween. Roller 78 is carried by arm 79 pivoted to the frame of the machine at 8O and is normally spring pressed against drum 59 by means of leaf spring 81. Members 61 are slotted as shown in Fig. 6 to permit of lateral adjustment of drum 59 as desired.

The shuttle reciprocating mechanism is operated through a cam wheel 82 loosely mounted upon shaft 89 (see Fig. 13) and provided with a cam groove 83 within which travels roller 84 secured to a vertically lifting link 85 which in turn is pivotally mounted upon a laterally extending arm 86 best shown in Fig. 1, and which in turn is secured to rock shaft 87 ournalled in the frame of the machine at 88. Also secured to rock shaft 87 is hub 89 of upwardly extending rocking arm 90, the upper extremity of which is pivotally and slidably mounted to block 91 (see Fig. 7) which in turn is aiixed to the rack 92. Then roller 84 is in that portion of cam groove 83 which lies adjacent the center of cam wheel 82, as shown in Fig. 2, rocking arm 90 is in the relative position shown in Fig. 7, that is, at the right-hand limit of its travel, looking from the front ofthe machine. As cam wheel 82 revolves in a clockwise direction, as shown in Fig. 2, roller 84 is forced through cam groove 83 toward the outer periphery, following the cam groove, and during this operation lifting link is forced downwardly, rocking shaft 87 by means of the connection with arm 86. This rocking operation of shaft 87 causes rocking arm to swing toward the left from the position shown in Fig. 7 until it reaches the opposite limit of its travel, which brings shuttle to the opposite end of the shuttle race from that shown in Fig. 7 lt will be noted that cam groove 83 is so formed that rocking arm 90 is held at each limit of its travel the same length of time, and, therefore, one complete revolution of cam wheel 82 causes one complet-e cycle of operation of rocking arm 90. That is, starting from the position shown in Fig. 7, rocking arm 90 is rocked toward the left, causing engagement of the rack 97 on the shuttle 95 by gears 98, shuttle 95 being held to the left of hatten 40, as shown in Fig. 7 for a short period of time while roller 84 is in the curved outer portion of cam groove 83, and shuttle 95 is reciprocated to its initial position shown in Fig. 7, all during one complete revolution of cam wheel 82. Rack 92 is slidably mounted for reciprocating` motion upon stationary housing 98 which is divided centrally for operation of the heddles, and rack 92 is held in place by plates 94. The shuttle employed is preferably of the type shown as 95 in Fig. 8 having a removable spool 96 and provided with rack teeth 97- along the upper edge, which are adapted to be engaged .by pinions 98 pivotally mounted within the housing 93. As rack 92 is reciprocated transversely by means of rocking arm 90, the gear teeth along the lower edge mesh with interniediate gears 99 also pivotally mounted within the housing 93. rlhe length of the shuttle is such that one of the pinions 98 is always in mesh with a portion of the rack 97, and further to insure smoothness of operation, shuttle 95 makes a dove-tail fit as shown at 100 in Fig. 9. It will be understood that shuttle 95 reciprocates transversely across the space occupied by the warp thread, passing through the shed formed by the warp threads in the usual manner, and as hereinafter explained, when the machine is automatically stopped to permit of a hand bohbin weaving operation as shown in Fig. 1, the shuttle is preferably at the right hand limit of its travel as shown in Fig. 7 As shaft 89 rotates, crank arm 101 secured thereto actuates connecting rod 192 which extends upwardly to a dobby or equivalent mechanism as shown in Fig. 3, and has its upper extremity pivotally mounted at 103 to arm 104 ot T-shaped rocking member 105. ln the present embodiment of the invention, a dobby mechanism is employed for manipulating the warp threads in conjunction with a pattern chain 106 as shown in Fig. 5. Referring to Figs. 3 and 4, it will be understood that the dobby mechanism includes a sutlicient number ot arms to handle the number of heddle frames employed, but in addition thereto an extra arm 107 is placed to the right of the dobby mechanism looking toward the rear oit' the machine, which is employed in the automatic stopping operation hereinafter described, and an extra arm 108 is placed upon the lett ci" the dobby mechanism tor use in connection with the starting operation after an automatic stopping operation as hereinafter described. The arms are pivotally mounted at 109 and T-shaped member 105 as well as lever 110 at the opposite side of the dobby mechanism are lixedly mounted upon rock shaft 111. Further, the upper ends ot members 105 and 110 respectively are pivotally mounted to adjustable links like link 112 which in turn are pivoted to sliding bar 113 which is adapted to reciprocate horizontally in slot 114 of frame 115. Similarly the lower extremities of members 105 and 110 are pivotally connected to a lower sliding bar 117 slidably mounted in slot 118. In accordance with the usual acquard, dobby, or equivalent mechanism, each arm has pivotally mounted thereon a lever provided with hook arms adapted to be engaged alternately by sliding' bars 113 and 117, but in addition thereto in the machine of the present invention, the right hand arm 107 has pivotally mounted thereon a similar rocking lever 119 pivotally mounted at 120 in the arm 107, and lever 119 is provided With the usual hook arms 121 and 122 adapted to be engaged alternately by slidingbars 113 and 117. Also additional arm 103 has pi-votally mounted thereupon a rock lever 128 normally held elevated by the oppositey end ofvlever 127, to drop downwardly, thus permitting the two lockarms of that particular dobby to be engaged by the reciprocating bars 113 and 117. For purposes of illustration a pattern chain has been adopted which carries two complete patterns, but in addition to the pins ordinarily provided for operating the dobby arms which manipulate the warp threads, provision has been made upon the pattern chain for an additional pin 129 (see Fig. which when it reaches the top of its travel, will operate the lever controlling actuation ot dobby arm 103, and also in addition thereto the pattern chain is adapted to carry an additional pin 130 at the'opposite side ot the chain, adapted tov actuate the stopping dobby arm 107 as shown in Fig, 3 in a similar manner. As previously explained, these two particular dobby arms 107 and 103 have nothing to do with 'the operation of the warp thread heddles but cooperate in the automatic stopping of the machine tor hand weaving operation, and the subsequent starting ot the machine following each such operation. Pattern chain 103 travels around sprocket 120 which is driven by ratchet wheel 131 engaged by double acting pawls 32 and 133 as shown in Fig. 3, both of which are pivotlly mounted upon the lowermost arm of member 105, and by this construction and arrangement, each downward travel of connecting rod 102 moves ratchet 131 one notch, and each upward travel of connecting rod 102 moves ratchet 131 the same distance. 1n the present embodiment, `tor illustrative purposes, the machine is adapted to automatically stop at a certain point in the pattern where 'four figure warpthread heddles are elevated, dobbies tor which are operated by pins 134. llVhen pin 130 of the pattern chain engages its cooperating lever, dobby arm 107 is moved toward the rightfrom the position shown in Fig. 3 which draws corr 1,35 trained over pulley 136 and cord 135 is connected to one end of bell crank 137, which is pivotally mounted at 133 to the frame ot the machine. rlhe opposite end of bell crank 137 has a cam surface 139 which when low-V 141. A clutch hub 142 keyed upon shatt- 39 is provided with slots 143 either of which may be engaged by plunger block 140, thus locking clutch hub 142 and cam wheel 82 to cause their rotation in unison. Then cam surface 139 of bell crank 137 withdraws block 140 of plunger 141 trom engagement in notch 143 of clutch hub 142, the shuttle has commenced travel toward the right, and the momentum of rocking arm 90, and the associated mechanism carries cam wheel 32 until block 140 is spring` pressed by spring 144 at the base of plunger 141 into the next succeeding notch 143. In other words block 140 rides upon the lateral surface of clutch hub142, but when block 140 has thus reached the next succeeding notch 143, the machine ordinarily has been brought to a stop as presently explained. lt will be understood that arm 137 is normally held out ot engagement by spring 145 and the upward movement of end 139 is also restricted by a stop pin 146 mounted on the :trame of the machine. Also, a spring 147 is preferably provided for normally maintaining cord 135 pulled taut.

Then pin 129 mounted at the opposite end of the next succeeding block upon which pin 130 is mounted, coacts with its appropriate lever 127, dobby arm 10S moves toward the right pulling cord 148, the lower end of which has a ring 149 (Fig. 6) through which extends a second cord 15() having a spring connection at each end. The upper end connects at 151 with arm 152 of a bell crank pivotally mounted to the frame of the machine at 153, the other arm 154 of which is provided with a horizontal surface As cord 148 is drawn upwardly, surface 155 is forced into the path-way of pin 156, thus disengaging the main clutch 27 and bringing the machinel to a stop. 1t will he understood that the shuttle operating mechanism has been disengaged just preceding this point. Clutch 27 is adapted to rotate in a clockwise direction, as shown in Fig. 11, when in engagement with pulley 24. Therefore, main clutch 27 is disengaged by surface being brought into engagement with pin 156, causing clutch shoe 31 to be swung slightly in a clockwise direction from the position shown in F ig. 11, which releases the gripping contact of clutch lining 28 against pulley 2l.

In this position clutch 27 is held stationary,

and consequently all of the operatingmechanism which derives power from shaft 25 is likewise stopped, although it will be understood that when this operation takes place the shuttle mechanism has alrearly been disengaged. Also, when clutch 27 is held out of engagement, as ust described, link 157, and consequently foot treadle 158, are slightly elevated by reason of the engagement of projection 155 with pin 156, and therefore the depression of foot treadle 153 withdraws projection 155 from engagement with said pin 156, causing reengagement of clutch 2? by means of spring 33 pulling arm 32 and in turn clutch shoe 31 in a counter-clockwise direction to expand the clutch arms. 1t will thus be understood that the disengagement of the shuttle operating mechanism previous to the disengagement of the main drive clutch, makes it possible to stop the shuttle at exactly the right point in accordance with the pattern, and also avoids the extreme shock which would be caused by attempting to stop the shuttle mechanism entirely through the sudden stopping` of the main drive clutch. The momentum of the shuttle operating` mechanism would cause excessive strain and possible breakage, and in this connection it is also to be noted that the shuttle mechanism disengagement is not a sudden disengagement, but the shuttle continues its throw after the disengagement takes place, by reason of the momentum of rocking arm 90 and the connected parts. Arm 152 of the clutch operating bell crank is pivotally connected to a link 157, the lower end of which is connected to a foot treadle 15S pivotally mounted at 159, and further, the lower extremity of cord 150 is connected at 159. After engagement of surface 155 with pin 156, the machine rc mains at rest until started at the will of the operator, which is done by depressing foot treadle 15S, thus withdrawing surface 155 from engagement with clutch pin 156 whereby the operation of the entire machine is resumed, inasmuch as cam wheel 82 has been brought into operative engagement with clutch hub 1412 for operation of the shuttle mechanism.

eferring to Fig. 9, the usual warp threads 162 are guided by means of warp guide 163 and the heddle frames 164e are connected by springs 165 near the bottoni of the machine and with the usual elevating cords 166, connected to the pattern chain controlled dobbies. Also the heddle frame wires are provided with the customary warp eyelets 167.

Freni the above description, it is believed that the operation will be apparent. A typical pattern is shown in Fig. 14, and the hand operation is performed upon the three cords 160 which are intermittently interwoven with certain ligure warp threads of the material. This is doi-1e by using a bobbin 161 as shown in Fig 1. "When the designated point has ieen reached, the machine is automatically brought to a stop through the initial operation of pin 130. rlhc operator then passes lgiobbin 161 through the shed as then present. wWhen this is done, the operator depresses foot treadle 158 causing themachine to assume its automatic loom operation until the pointis a `gain re ched in the pattern where it is desired to repeat the operation by hand using bobbin 161. From the foregoing, it will also be understood that at each automatic stopping of the machine, shuttle 95 is at the right hand travel of the shuttle race so as to maintain uniformity in the pattern. 1t will also he understood that a wide variety of patterns mav be adopted utilizing the present invention, and a practically unlimited com-l bination of machine and hand loom operations are possible.

For purposes of disclosure, the preferred embodiment of the invention is shown in operative association with a particular type of pattern forming mechanism, but it will be apparent that the invention is adaptable to use in conjunction with any form of pattern mechanism, such as the acquard, dobby, or cam types, bv making the necessary formal changes, and therefore applicant desires not to limit the invention to the particular type of pattern forming mechanism disclosed, or to any particular type.

While I have illustrated and described the preferred form of construction for ycarrying my invention into effect, it is capable of modiiication and variation without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction as set fortli;'but desire to avail myself of such modifications as come within the scope of the appended claims.
