3 Claims. (Cl, 164-112) The present invention relates to certain new and useful 2,774,428 Patented Dec. 18, 1956 cry for retaining each disc in one of their three operaimprovements in so-called card-punching machines for punching the holes in the pattern-card or inthe patternpaper or pattern-roll or band used in controlling the pattern mechanism of a knitting machine (or other textile machine) such as a Jacquard type knitting machine and other Jacquard controlled textile machines.

The present invention relates to a mechanism for insuring the non-overlapping or non-duplicating selection of punches, for the successive colors of the same course,-and also for minimizing the labor involved in making the selection of punches.

In pattern-punching machines of this general class (ineluding but not limited to the 70 lever duplicator designpunching machine made by the Jacquard Knitting Machine Company of Philadelphia and described in its 1946 instructions booklet), the punch-selector bars or levers i are selectively interposed between depressor-head or press-bar of the punch-mechanism and the hole-punching pins. Each punch-selector bar is generally provided with a rear terminal knob or up-standing handle-like portion or tab, by means of which the punch-selector bar can be manually pushed in, into operative position. While these tabs are here referred to as being on rear-ends of the punch-selector bars, yet in common parlance the tab end of the heretofore conventional machine was referred to as the front of the machine, because it is at this end of the machine that the operator must bein I order to operate the machine. These upstanding tabs were usually numbered (in groups of ten) from 1 to' 10, and this numbering is' repeated with every tenbars. -.After the barsselected (for aparticulor-color iii-a course-of knitting) are pushed in, thepunchi'ng'mechanismofithe machine is actuated or moved through one completec'ycle, by manually turning a'handwheel through orie'revolution.

During .the .last' portion of the revolution of therhamib wheel (in the heretofore conventional design p'uuching machine) the theretofore selected bars we're-retracted by hand wheel-and returned totheirtofiginal*inop'eratiye positions. This same turning of the-hand wheel'also advanced the pattern paper or band lOifilB ne'xt.position. The operator then selected the nextgroupvof'ibars (according to't'he pattern drawing) for" the next? color'inithe same course,'andthe hand-wheelwas .again turnedeand the punching operationthus performed-on theinext'zposition of the paper; andiso for thethird colorranother group of these bars are selectedand'the?punchingToperation there performed for the third-aposition oftthef paper v (and so forth for 'a'- fourth" color,zifrtlie're "be-1a fourth color in the same course). i

: By this prior practice the operator had' to'ibe fc'arful not to select. the same bar twice withinthe sam'eacourse (unless .for making a half stitch). However, liability; of

- error was very great because eachitime a new set 'of bars was to be selected for the same course,- all the1the'retofore. selected bars-and-tabs: were in Itheir' retrac'tedtor initial position; Thus, great care'had toibe exercised so as notInnintentionally, oriby mistake, to'iselecfionerof tive positions.

The disc-bearing shaft is, in turn, ournalled in a pair of journal blocks which are slidably mounted in horizontal guide-ways and are reciprocable to and fro, so as to reciprocate the entire group of discs and push them against the ends of the selector bars; the pair of journal blocks being rigidly interconnected through a connecting yoke-bar in front of the disc, which yoke-bar carries spring-pressed disc-retainer balls (one for each disc); the

3 two journal blocks and the yoke-bar forming a generally U-shaped frame in which the discs and disc-shaft are journalled.

; By pushing (turning) as by manually through the use of a hand stylus or by other means such as through a 1 master pattern strip (or card), which has been prepuuched the selector-tabs of the desired discs forwardly, to their first position, the push-projection of the corresponding disc is turned into alignment with its punchselector bar, so that when the entire group of discs is .advanced; against the punch-selector bars, only those'bars will be pushed into their operative positions whose discs .havebeen so turned. Upon the return stroke of the entire group of discs, the theretofore selected and turned selector-tabs strike a pivoted overhead pawl-bar, which .then further turns the theretofore selected discs until the push-projections thereof are below the level of the punch-selector bars. This overhead pawl-bar is'pivotally mounted on the stationary frame member which provides the aforesaid guideways,'so that the pawl-barmay raise upwardly slightly to permit the selector-tabs of the discs to be turned freely and then to be advanced freely underneath the pawl-bar (first on the manual turning and subsequent advancing stroke of the discs). The pawl-bar then drops behind the tabs and so engages them on the return stroke of the discs, so as to further turn the selected discs into their inoperative positions on the return-stroke.

In this manner the set of discsv selected for any color are put out of action and beyond the reach of the operator .when he proceeds to select discs for the next color in the same course.

The last color to be selected for the course ordinarily involves allof the remaining needles '(or heddles) for which the pattern-hole-punches had not been selected for the previous colors within the same course. By'the machine or apparatus of the present invention this last color pawl-bar beneath the disc-group enters the normalizing notches in all the discs (now aligned for the first time), so that upon the last portion of such return-stroke of the disc-group, their engagement with this lowerpawl-bar causes all discs to be counter-rotated to their initial or starting positions for the next course.

An idle press-roll 63 serves to press the paper 57 against the feed-roll or propelling-roll 58.

The following is a description of the control mechanism and other related mechanisms of the present invention in relation to the above described punching machine.

The frame 71 of the control mechanism of the present invention may be aifixed to the frame 25 by means of a flange 72 bolted or otherwise secured to the frame 25. Upon the frame 71 pairs of horizontal guide-rails73 and 74 are mounted upon posts 75 and 76. A generally U-shaped slide-frame 77 having pairs of guide-rollers or wheels 78 and 79 pivotally mounted to the outer surfaces of the opposite legs of the U, is supported between the rails 73 and 74 by means of the wheels 78 and 79 which project between said rails and serve to support the U -shaped slide-frame for to and fro horizontal movement in the direction of the arrows 80 and 81 (Figure 2). A central shaft 82 is mounted in and across the two legs of the U-frame 77. Upon the shaft or pivot bar 82 the control-discs 83 are pivotally mounted, each capable of being turned independently of the other. Each disc 83 is provided with a push-projection 84 and a selector-projection 85. A return-notch 86 is provided at each disc adapted to be engaged by the return-pawl 87 when the U-frame 77 is on its return stroke after all the discs 83 have been turned (so that the pawl 87 may enter all the notches 86). Retainer notches 88, 89 and 90 are provided in the outer periphery of each disc, into which a retainerball 92 may enter under the influence of the spring 93 housed and confined in a corresponding hole in the basebar 94 of the U-shaped slide-frame 77; the back ends of the springs 93 being held and buttressed by the coverplate 95 which covers the outer ends of all the spring holes; the plate 95 being held in place by screws entering the base-bar or block 94. The notches 88, 89 and 90 correspond to the three positions of the discs. Notch 88 corresponds to the retracted or initial position of the discs shown in Figure 4, wherein the push-projection 84 is just above and not in alignment with the selector bar 43. The notch 89 corresponds to the first advance-position of the push-projection 84, in which position it is in alignment with its corresponding selector-bar 43. The notch 90 corresponds to the second advance-position or the downposition of the push-projection 84, namely, the position in which the push projection 84 is just below and out of alignment with the selector bar 43 (and in which position the return-notch 86 has closely approached the pawlbar 87).

A shaft 97 is journalled in and extends through the frame 71 and has at each of its outer ends a lever 98 affixed thereto and keyed or pinned thereto. The upper ends of each lever 98 are provided with a longitudinal slot 99 which receives the reduced outer ends of the shaft and pivot 82 as indicated in Figures 1, 2 and 5. The lever 98 on one or both sides of the machine is connected by means of a connecting rod 100 (pivoted to the lever at 101) to the crank pin 102 carried by the end of the crank 103, which, in turn, is carried on the end of the main or drive shaft 26 and the angle of the crank 103 on the drive shaft 26 is such that the connecting rod 100 will be moved in the direction of the arrow 104 when the press-bar 41 has cleared the ends 56 of the selectors 43 and will move in the direction of the arrow 105 while the press bar 41 is on its down stroke (see Figure 1).

For purposes of adjustment of the stroke of the disecarrying U-frame 77, the connecting rod may be made adjustable, in length, by having its two pivotable ends 106 and 107 screw-threadedly connected to the central portion 100 thereof, withsuitable lock- nuts 108 and 109 to lock the ends 106 and 107 at the length-determining setting or adjustment desired.

Directly above the group of discs 83, a diagram-feeding shaft 110 is rotatably mounted in the journal- blocks 111 and 112, which, in turn, are carried on the upper stationary rails 74. V

Upon the shaft 110 the diagram-magazine designated generally by the numeral 113 is pivotally mounted, with a stabilizing bracket 114 afiixed thereto and extending downwardly and with its lower end 115 screwed to the stationary upper rails 74 (Figure 2 and Figure 6), thereby to keep the diagram-magazine and feeder upright even though pivotally supported upon the shaft 110. The diagram-magazine and feeder may be formed of a pair of side-plates or journal members 116 and 117, which have bearing-openings through which the shaft 110 passes. A pair of frame and spacer rails 118 and 119 extend upwardly from and are aifixed to the end bearingmembers 116 and 117. To the vertical rails 118 and 119 the front magazine wall 120, the rear magazine wall 121 and the intermediate separator orpartition wall 122 are aflixed in the manner indicated in Figure 11; the plates or panels and 122 being screwed to the rails 118 and 119 from opposite sides, while the plate or panel 121 has forwardly bent terminal flanges 123 disposed at a right angle to the panel, which are screwed to the rails 118 and 119 from the sides.

A diagram-feed roll 124 of suitable material (perhaps similar to the material of a typewriter roll or the like) may be mounted upon the shaft 110, intermediate the terminal plates 116 and 117, or, the shaft 110 itself may be increased in diameter through its portion which is intermediate the members 116 and 117 so as to act as a paper-feeding or diagram-feeding roll. A guide plate 125 is fastened to the members 116 and 117 at a point slightly below the lower edge of the front panel 120, with its lower edge 126 flared inwardly slightly so as to better feed the diagram-paper to the roll 124. A gap 127 may be left between the upper edge of the plate 125 and the lower edge of the panel 120, so as to expose a part of the diagram at that level. The diagram-roll 124 and the lower edge 126 of the guide-plate 125 are so disposed that when viewed from the front in the direction of the arrow 128 (Figure 10) only a single row or line of the diagram is exposed to view beneath the lower edge 126 of the plate 125, and the so-exposed single line of the diagram will be directly above and in close proximity to the row of turn-projections 85 of the discs 83 as indicated in Figures 9 and 10. The rails 118 and 119 are spaced apart from each other just at the right distance to accommodate the width of the diagram-paper 129, so that the rails 118 and 119 will keep the diagram-paper in vertical alignment with the bank or row of discs 83 and projections 85, as indicated in Figure 9.

The terminal or side plates or members 116 and 117 are provided with an inclined slot 130, into which the trunnions 131 of an idle-roller 132 are adapted to be disposed. The idle-roller 132, bears against the upwardly moving portion of the diagram-paper 129 and serves to keep the paper 129 in the desired path so that it will travel into the rear compartment formed between the plates 122 and 121. A knurled knob 133 is secured to one or both ends of the diagram-paper shaft 110, by means of which the diagram may be advanced, a line at a time, so as to expose successive lines in the manner indicated in Figure 9. If desired, an automatic feed by pawl and ratchet or star wheel and pawl may be applied to the shaft 110 so as to advance the diagram by one line each time the finishing lever 134 is raised for the turning of the balance or remaining discs required to finish the c'ourse'of knitting (the operationiof the finishing levers 1. 5 i -fi i t g described more indetai l hereinafter). 7

. Thelower back-turning pawl 87, for turning the discs backwardly towards the initial position after they have been all turned forwardly, is in the form of a bar extendingcompletely across the entire row of discs-83 and isfca'rried from a; pair of lugs 136 -and137which are af:

fixed (by do wel pins,' taper pins or otherwise) to the pivot shaft 138 ('see Fig. 8); The pivot shaft 138 is, in turn,

journalled in the journal'blocks 139 and140 aflixed to or carried by the frame 71. A stop lug 141'-is also similarly afiixed to the shaft 138 with a finger142 extending outwardly therefrom which serves as a stop member'bearing against the cross-bar 143 which extends across the opposed side framemembers 7'1. The stop-finger 142 serves to limit-the upward deflection of'the pawl-bar 87. A lever is similarlyafiixedto the, shaft 138, and to its lower end a tension'spring 145 is anchored (Figure 2) with-the other end of the spring anchored to some stationary part of the machine, so as to exert'a constant force upon the lever in the direction of the arrow 146 (Figure 2), thereby exerting a turning force upon the shaft 138 which tends to deflect the pawl-bar 87 upwardly, so that it. will enter the notches 86 of the discs 83 when all the notches 86 are in alignment with each other, whereby the entire group of discs are returned to their starting position after a the finishing lever 134 has been operated. a

' Fromithe diagram-feeding shaft 110 an upper pawl bar 147 (see Fig. 4) is pendently supported by means of the pivotal members148 and 149 which are journalled on the shaft 110 and are afiixed to the ends of the pawl 147. When the U-frame 77 with the discs 83 moves through its forward stroke in the direction of the arrow 80 (Figure 4), such of the turn-projections 85 as have been pushed forward (by the operator) away-from the finishing bar 135 against 'which they initially rest, will slide underneath the pawl-bar 147 (raising it slightly to get past it), and upon the return stroke of the discs 83 (in the direction of the arrow 81) the so-turned projections 85 will be engaged by the lower edge of the pawl shoulder 15% spaced at a predetermined distance 151 i from the free end 152 thereof, is provided. The operator rests this tool upon the finishing-bar 135 and brings it into alignment with the projection 85 to be turned. By

, then pushing the'tool 150 forwardly until the shoulder 150a stops against the finishing-bar 135, the selected projection 85 is turned a distance just'sufl'icient to turn the disc 83 from the engagement of the notch 88 to the engagement of the notch 89 by the retainer ball 92; which advancement turns the push-projection 84 into alignm'entwith thecorresponding selector-bar. 43. 7 The pair of finishing-levers 134 are affixed to the pivotsha'ft 82 upon which the discs 83 are rotatably mounted, 'so that by raising one of the levers 134 the other one will raise correspondingly through its interconnection through the shaft 82. One or both of the levers 134 is provided with a handle'153', so that it may be more conveniently raised. The finishing bar 135 extends across the two levers 134 and is affixed to an upward extension or projection 154 on each of said levers 134.

The light-box 158 is preferably supported at itsbottom, upon the gear 163, and the upperend of the light-box is-preferably open, so that a small tubular or other suitable electric light bulb, stationarily supported within the housing 156', from the upper wallfthereof, may'extendinto the revoluble' light-box 158 so as to light upthe four colored windows provided in each of its four sides.

In addition, ight-openings174, 175,176, 177, 17s

and 179 mayalso be-provided in the'front wall of the.-

indicator 15 5 (facing the operator). These openings may be provided with suitably colored panels correspondinglto the .colorings of the light-box Windows, and another electric'bulb positioned-behind these openings 175 to 179. An opaque partition may; be providedbetween the electric light bulb -which'is behind and illuminates the openings 175 to 179;"and the light box 158, so that the electric light bulb which is used to illuminate the openings 174 to 179=will not cast any light behind the openings159 'to 162; r a

The main'or drive shaft 26 'is caused to'revolve a single revolution, after each return stroke of the U frame 77, anddiscs 83 (in the direction of the arrow 81) and after the operator has selected and turned the next group of projections 85.- 'This is done by the operator stepping on the treadle 180 carried bythe arm or lever which passes through and is guided by a pair of station-' ary guides and 186 carried by the lower frame'or pedestal"1 87 o f the machine] The down-movement of the rod 184'is again'stthe spring-1 88-which surrounds a portion of the rod intermediate the: lower stationary guide 186 and the spring-abu'tmentcollar 189 aflixed.to

the rod'184 by-a set screw or the like. One half of the; cylinderv comprising the rod 184 is cut away at its upper end so as to present a flat surface 190, and the rod is further recessed along its upper flat portion as at 191, to provide a slight shoulder 1 92. .The upper end of the rod'extends through the vertical opening 193 in a clutch box 194, which is provided with a horizontal transverse bearing opening 195. The clutch box 194' is disposed between the forked ends 196 of the lever 19.7 which is pivoted to the frame 25 of the machine by means of the pivot pin 198. The other end of the lever 197 terminates in a finger 199. A link 200 is pivoted to the other end of the lever 197 bythe pivot-pin 201.-

A clutch arm 202 pivoted to the frame of the machine by means of the pivot pin 203 is, in turn, pivoted to the link 200 by means of the pivot pin 204 so that a turning of the lever 197 in the direction of the arrow 205 causes the lever 202 to be deflected in the direction of the arrow 206, while a deflection of the lever 197 in the direction of the arrow 207 causes the lever 202 to be deflected in the direction of the arrow 208. The lever 202 is provided with a shoulder 209 against which the finger 199 abuts when the lever 197 is deflected in the direction of the arrow 207, so that such deflection will cause the lever 202 to deflect in the direction of the arrow 208, without permitting the link 200 to fold in the opposite direction.

The pulley-wheel 210 is not keyed to but is revolubly mounted on the main or drive shaft 26 and the inner face of the pulley 210 has a pair of lugs 211 facing towards the machine. These lugs are spaced apart from each other so that they form intervening recesses 212 between the spaced-apart ends of the lugs 211.

A clutch hub 213 is keyed to the shaft 26. The hub 213 has a flange 214. A clutch-bolt 215 is slidably mounted in the hub 213 and flange 214, which are recessed to receive the bolt 215. The bolt 215 is provided with a notch 216 in the outermost side thereof, with a 'wall 217 of the notch inclined or flared. A helical compression spring 218 is interposed between the bolt 215 and an abutment plate 219 secured to the hub 213 by means of the screw 220, so as resiliently to urge the bolt 215 in the direction of the arrow 221, namely, in the direction of the pulley-wheel 210 and the lugs 211 and recesses 212 thereof. In order to accommodate a number of convolutions, the bolt hole or recess of sufficient depth 218 is recessed or housed. clutch lever 202 is curved spring 218 of adequate 215 is provided with a in which a part of the spring The free end 222 of the to the curvature of the hub213, and the end 223 thereof is thinned out so as to permit it wedgingly to enter into the notch 216 of the clutch-bolt 215 by engaging the inclined entrance-surface 217 thereof. When the clutchlever 202 is in its bolt-engaging or power-off position shown in Figure 13, its leading edge 223 enters the notch 216 of the bolt 215 and so retracts it until the end of the bolt 215 which faces the pulley wheel 210 is fully withdrawn, flush with the surface of the flange 214. When however the clutch lever 202 is deflected in the direction of the arrow 206 (by the deflection of the lever 197 in the direction of the arrow 205) it is withdrawn from the circular path of the bolt 215, so that the bolt 215 is instantaneously projected into its operative position shown in Figures 21 and 22, and thus enters the next recess 212 on the face of the pulley-wheel 210 and is engaged by the next approaching lug 211. By this engagement, the hub 213 and flange 214 are rotated and hence the shaft 26 to which they are keyed is rotated. If the clutch lever 202 were kept so retracted, the shaft 26 would be rotated several or many revolutions. However, the arrangement of the rod-clutch mechanism shown in Figures 14 to 18 inclusive, together with the knockoff mechanism shown in Figures 12 and 13, is such that when the hub 213 and flange 214 have been revolved through one revolution (or, indeed, just before they have completed one revolution) the clutch lever 202 is agai n deflected in the directionof the arrow 208'into the path of the oncomingbolt 215 so as to re-enter the notch 216 thereof and thereby withdraw the belt 215 from operative engagement-with the pulley wheel 210; The clutch lever 202 has a stop-lug 224 aflixed thereto, facing the inner end 225 of the bolt 215, and in alignment therewith, 'so that when the lever 202 is in its position shown in Figure-l3, the inner end 225 of the bolt 215 willbe brought to a stop by the lug 224, thereby bringing all' power driven parts of the machine to a standstill at a predetermined point of their operative cycle. The lug 224 is preferably recessed slightly into the face of'the' lever 202, or is given lateral support by the shoulder 226 formed on the lever, and is bolted thereto by means of the bolt 227.

The ro'd-clutch-box 194 is pivoted between the forked ends 196 of the lever 197 'by'means of the cylindrical clutch pin 230, which is provided with a notch or a cutout 231 to approximately one-half the diameter of the pin, for a length and in a position corresponding to the location of the half-round portion of the rod 194. An arm 232 is keyed or pinned to the cylindrical clutch-pin 230, so that a deflection of the arm 232 will cause the clutchpin to revolve or to be turned correspondingly.

A helical compression spring 233 is interposed between the turned end 234 of the arm 232 and the lower side of the lever 197. Small spring-anchoring or springretaining recesses 235 and 236 may be provided for the arm-end 234 and in the'lever 197, respectively, so as to keep the spring in position.

The force of the spring 233 upon the arm 232 urges the clutch pin 230 to rotate or turn it in the direction of the arrow 237 so as to cause its clutching edge 238 to engage beneath the shoulder 192 formed in the half round portion of the rod 184 in the manner indicated in Figure 17. In this position a down-pull upon the rod 184, by means of the treadle 180, will cause a downward deflection of the forked end of the lever 197, in the direction of the arrow 205 and will, in turn, deflect the clutch-lever 202 in the direction of the arrow 206 so as to withdraw the clutch-lever from engagement with the clutch-bolt 215 and to permit the latter to enter into driving engagement with" the pulley wheel 210. The knock-off lever 239 is pivoted to the machine frame member 25 by means of the pivot bolt 240. The end 241 of the lever 239 is in vertical" alignment with the flange 214 carried by the 'clutch-hub 213 and, more particularly, is in alignment with a knock-off projection 242 carried by and projecting from said flange. The other end 243 of the knock-off lever 239 has an adjustable abutment 244 thereon, which may be made in the form of a screw threaded through the lever-end 243 and held in any desired setting or adjustment by means of a lock-nut 245. The end of the screw 244 is in alignment with the underside of the end of the arm 232. The projection 242 is so positioned in relation to the position of the clutch-bolt 215 and the lever-end 241, that the projection 242 will strike and deflect the lever end 241 in the direction of the arrow 246 by an amount sufflcient to deflect the arm 232 and to turn the clutch pin 230 out of clutch-engagement with the halfround portion of the rod 184. Thus released from the down-pull of the rod 184, the lever 197 is at once deflected upwardly in the direction of the arrow 207, by means of the helical compression spring 247 which is interposed between the forked ends 196 of said lever 197 and the upper stationary rod-guide 185 (a washer 248 intervening the upper end of the spring 247 and the forked ends 196 of the lever 197). When so deflected upwardly in the direction of the arrow 202 (when so released from the downward pull of the lever 184) the lever 197 again deflects the clutch-lever 202 into the path of the clutchbolt 215 so that when the bolt 215 approaches the end 223 of the clutch lever 202 said end enters the notch 216 thein'cycle after each reyo lntion'efthe shaft; 29
