Specification of Letters Patent; 7 Patented Oct. 14,

Application filed February 20, 1919. Serial No. 278.208;

To all whom it may concern Be it known that 1, JAMES A. GRUNDY, citizen of the United States, residing in the city of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Jacquard-Card-Punching Devices, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

The invention has for its purpose, the perforating or punching of jacquard cards, used in Jacquard loomsand similar devices,

and more particularly, has for its purpose,

the simultaneous punching of two or more cards which are to be subsequently coordinately used upon such devices, whereby a plurality of patterns to be woven may be simultaneously controlled and so combined as to considerably shorten the length of the usually endless chain of cards.

It is the present practice in perforating jacquard cards to utilize finger controlled punching heads with twelve and occasionally sixteen punching plungers. Inasmuch as all of the finger operated control keys must be held in locking position by the fingers during the time of the perforating or punching operation of the machine, it is impossible in such structure to remove any of the fingers from certainof the operated keys in order to operate certain others with out the first-mentioned keys returningto ineffective position, and consequently, it has been diflicult heretofore to' operate more than twelve keys by the finger control and holding method, while extraordinary iSkll'l is required inunanipulating sixteen keys.

The invention herein disclosed, therefore,

has for its principal o'bjectstlie overcoming of the above difficulties and also for. the permitting of the use of an indefinitely large number of punches either in a singlesystem or. in multiple, whereby the finger keys may be operated and when so ope-rated, will remain in punch-locking position. when the fingers are removed-from said keysto other keys until the operatoroperates the perforating mechanism, and subsequently the means for positively returning the keys to ineffective or inoperative position.

In attaining these objects generally under the name ofRoyal piano I preferably utilize existing perforating means-known;

heads, andadapting the same, in a manner hereinafter more fully disclosed, to the partlcular' purposes indicated.

' Another "object is to enable; one to utilize a'finger keyboard from which tocontrolthe locking rods rather than directly moving the rods into locking position as in the old form" of device. i V

A further obj ect is to employ an electrical system-controlled fro-1n said keyboard and effective to' influence the selected-and proper movement of the locking pins by means of electromagnets connected inthe circuits of the system.

further object is also to provide certain vis ble signals, as. colored lights, operable to indicate the particular circuit or circuits, and pin or pins controlled from the finger operated keyboard.

A further object is to provide a special form of circuit closing. means for so controlling the circuits that the' chance of interference of the circuits of one set of the perforating devices with another set is absolutely avoided.

A further object is 'to' provide means whereby the circuit closing devices may be all returned to theneutrazl or the inoperative position by the operation of a single finger operated means i I 'A still further object is to providem'eans whereby in the event that it is desired to repeat a design or pattern in any set of the perforating devices, the circuit closing means of the other circuits may be. broken or returned to neutral or inoperative position, While those to be repeated remain in operative connection for the next punching operation, thereby avoiding the necessity of again j mampulatlng corresponding keys therefor upon the keyboard.

A still further object is to so construct the devicethat the switches or the circuits may be controlled in a converse manner, that is,

all the circuits may be initiallyc'losedand the pattern or design to be produced 'efi'ected bythe opening of certain-of the circuits by the returning of the corresponding keys on the key-board to neutral position.

A still further object is to employ supple Cir ticular design effect or pattern, such as a twill, a satin, a honeycomb, or the like.

A still furtherobject is to so arrange and connect the circuit controlled means that a composite pattern or design may be produced from the combined operation of both the supplemental and individual selective switch means.

Another and still further object is to enable me to perforate correlated cards in multiple, the particular form of means chosen for illustration here operating upon two cards of which one contains the pattern of the other with an additional pattern. 7

These and other objects and advantages flowing from this invention will be disclosed in the following specification and appended claims. I

For the purpose of c'arrying'out the invention, one formof device or embodiment of the invention is more fully described in the specification and illustrated in the drawings. I

Referring now to the drawings, in which the same reference characters indicate the correspondingelements in the various views:

Figure 1 is a plan view, in diagrammatic form, of a pair of punching heads with the connected electromagnets and of the finger keyboard, as well as the wiring diagram forming the first and second circuits of each set; v Y

Fig. 2 is an end view, partially in section of the keyboard and circuit closing mechanism.

Fig. 3 is a view partly in transverse section of the perforating device;

Fig. 4 is a fragmentary illustration of the usual form ofchart used in connection with the finger keyboard for obtaining the patterns punched in the cards;

Fig. 5 is a broken plan sectional view of the keyboard showing more particularly the suplementary circuit closing means.

Fig. 6 isa transverse section of the means shown in Fig. 5. I

Figs. 7 and 8 show two of the contact bars that may be used in the supplementary circuit closing means shown in Figs. 5 and 6 as well as that shown in Figs. 9 and 10.

Fig. 9 is a view similar to Fig. 5 of a modification of the means shown therein.

Fig. 10 is a transverse section of the means shown in Fig. 9; and,

Figs. 11, 12 and 13 are fragmentary portions of design charts showing examples of the type of pattern that may be obtained with the supplementary circuit closing means shown in Figs. 5, 6, 9 and 10.

The mechanism employed comprises two punch heads, 1 and 2, usually termed Royal piano heads, which are each provided with sixteen perforations, 3 and 4, and in which are adapted to vertically reciprocate the perforating or punching plungers 5 and 6.

The heads are also provided with lateral perforations 7, 8, 9 and 10 through which are adapted to reciprocate the locking rods 11, 12, 13 and 14 connected at an end thereof to the armatures 15, 16, 17 and 18 of the electromagnets 19, 20, 21 and 22, suitably mounted upon brackets 23 secured to the undersurface of the table 24. WVhen any of the electromagnets are energized, the armatures are caused to swing about the pivots 25 toward the cores 26 of said electroniagnets and reciprocate the locking rods through their corresponding lateral perforations, provided in the heads 1 and 2, t interpose the ends 27, 28, 29 and thereof immedi-' ately above the upper ends 31 of the punching plungers, the coil springs 27, 28, 29 and 30 operating to return said locking rods to ineffective or inoperative positions when the electromagnets are deenergized. Any tendency of the punching plungers t subsequently move upwardly is thus impeded by said ends 31. Consequently, upon a downward movement of the heads 1 or 2, and the punching plungers, toward'a stationary body, the lower end 32 of a punch ing plunger, will contact therewith and the locked punches operated to perforate the body while the other punches will be caused to retreat through and in the perforations 3 or. 4. This body is usually in the form of a sheet of card-board, 33 or 34 which is--intermittently fed between the die plates 35 and 36, through the holes 37 and 38 of which the ends of the punching plungers are adapted to be guided during the punching operation.

The heads 1 and 2 are also provided with larger perforations 39 and 40 in which are adapted to reciprocate punching plungers 41 and 42 for the purpose of perforating peg holes in the cards at suitable places. These plungers are also controlled by locking rods 43 and 44 controlled by electromagnets 45 and 46 mounted upon the lower side of the table" in a'manner similar to the electromagnets hereinbefore described. The ends 47 of these punching plungers are also guided through the holes 48 in the die plate 35 during their punching operation.

Upon the table 24 is provided a finger operated keyboard or switchboard which is utilized for the purpose of controlling the locking rods referred to above. Inasmuch as there are sixteen pattern punching plungers in each head, two sets of finger keys, 49 and 50, of which there are sixteen in each set, the keys 50 of one set being operated for the control of the punching plungers in the head 1 and the finger keys 49 of the other set being operated for the purpose of con trolling the punching plungers in both heads 1 and 2.

The finger keys are rigidly mounted upon the vertically reciprocable tems 51 and 52,

passing through the table'and pivotallysecured to the ends 53 and 54: of the cross-bars 55, which are fulcrumed upon a shaft 56 To the-ends of the cross bars are pivotally connected the links 57 and 58 in connection with contact plungers 59 and 60, the ends of which are adapted when reci rocated to contact with and close the gaps 'etween the spring contacts '61 and 62, suitably mounted upon and insulated from the table or base,

for the purpose of closing an electrical circuit including said spring contacts.

At the end of the switchboard is also provided the addition finger keys 63 and 6a connected to the cross-rod '65, circuit closing means identically the same as that shown in Fig. r This additional circuit closing means is utilized for the purpose of controlling the circuits to the electro-magnets 15 and 4:6 and the large punches 4:1 and 42 for the peg holes referred to hereinbefore.

Located above to overlie the cross bars .55 and 65 are the horizontal bars 66 and 67 "secured to the vertical rods 68 and 69, recip- 25 rocable through the table and provided at the upper ends thereof with the finger bars 70 and 71, which extend across the full width of the finger-board.- The lower ends of the rods 68 and 69 pass through the lower partition 72 of the table or machine frame to be guided therethrough and are surrounded by the coiled springs 73 and 7 reacting at one end a 'ainst the stationary bosses 75 and at the other end against the collars 7 6 and 77 3 suitably secured to said rods. The cross arm 78, which isprovided at the ends thereof with the bores 79 and 80 through the rods 68 and 69 are adapted to slide, is located im mediately above the collars 76 and 77 and is connected by the link 81 -to the finger operated lever 82 pivotally mounted to the table or machine frame at 83. Surroundingthe contact plungers 59 and 60 are located the sleeves 8%, 85, 86 and 87 whichmay be made 5 of any suitable nonconducting material, the spring contacts 61 and 62 being secured to the sleeves 8 1 and by any suitable means, such as screws. I The shank portions 88] and 89' of the 00 spring contacts may be in the form of busbars extending the full length of the switch board and respectively connected to the leads 90 and 91from the electrical feed wires 92 and 93, the corresponding-shank of the 55 contact springs of the additional switches at the end of the switch-board being both connected to the lead. 90; V -Upon the table 24 and opposite each of the finger keys 419 and 50, are disposed col- 6O ored lights 94 and 95, those adjacent to the keys 49 being of one color, in this case, red, and those disposed adjacent to the keys 50 being of another color,"in this case, green.

The electric wire system utilized for car- 65 rying out the operation of this invention is may be used is that of a voltage of six volts between the wires 92 and 93, as well as, between the wires 93 and 96 and a voltage of twelve volts between the wires 92 and 96. 75

This system isuseful where it is desired to operate electro-magnets in various combinations, that is, where one or more are thrown in circuit in series. Where one pair of electro-magnets (see Fig. 3) only is included in 0 a circuit, the latter may be made from the wire 93 to wire 96 between which there is a voltage of six volts, which is sufiicient to operatively energize a single pair of electromagnets, while on the other hand, when it is 85 desired to include in a circuit two pairs of electro-magnet in series this circuit should be made from the wire 92 to wire 96 between which there is a potential of twelve volts, which is ample to effectively energize 9'0 said electro-magnets.

The red lights are connected in a closed shunt with the circuits of the electro- magnets 19, 20, 21 and 22 and are used to indicate that the electro-magnets, 19and 21 or 20 and 22, controlling the corresponding punches of each head, are in series and are energized and that the corresponding perforations will be made in both cards 33 and 34. The green lights are connected in an open shunt circuit with the circuits of the electro-magnets 19 or 20 only and, therefore, indicate which of the electroqnagnets 19 or 20 is'in circuit and energized and that the corresponding perforations will be made in the card 33- only. This shunt circuit leads through the contacts 97, 98, 99 and 100 or 101, 102, 103' and 104, as the case may be, of which the contacts 97, 99, 101, 103 are mounted upon thelocking rods 11, 13, 12 1 10 and 14 respectively and movable therewith, toward or from the stationary contacts 98, 100, 1 02 and 104 fixed to the table 2%.

The contacts 97,, 98, 101 and 102 are nor- 7 mally out of contact and the contacts 99, 5 100, 103 and 104 are normally in contact. Whenever a circuit isclosed to operate any of-the punches of head 1 the locking rods therein will carry a contact 97 or 101 to the stationary contact 98 or 102 to thereby close the circuit, the other contacts remaining in their normally closed position, and the corresponding green light indicates the particular holes punched. If however, a circuit is closed to operate any of the corresponding punches in both heads 1 and 2, notwithstanding the fact that the contacts 97, 98, 101 and 102 will operate as described above, the contacts, 99, 100, 103 and 104, however, will separate and this circuit broken, since the locking rods in head 2 are caused to move into locking position thereby carrying the contacts 100 and 103 away from the stationary contacts 99 and 104. This prevents the lighting of the green lights accordingly.

' Inasmuch as the red lights are in shunt with the energizing circuits of the electro-mag: nets they serve to indicate in the manner heretofore stated.

From the above description, it is apparent that when one of the keys, as for example 49, is depressed to the dotted line position shown in Fig. 2, the cross bar 55 is caused to turn about the shaft 56 and the contact plunger 59 moved downwardly through the sleeve 86 into the gap between the spring contact 61 to engage therewith whereby an electrical circuit is closed. Operation of a key will similarly swing a cross bar about the shaft 56 in the opposite direction and close another circuit by movement of another plunger 66 in contact with the other spring contacts 62. Those first mentioned were on the side of the board termed the red side and those last mentioned, on the side of the board termed the green side.

After a number of keys on either or both sides of the finger board have been operated to close the circuits in the manner above described and the punching apparatus has been operated, and in the event it is desired to return all of the cross bars 55 to the horizontal position shown in Fig. 2 thereby breaking all of the circuits the operator presses down upon the lever 82 thereby causing the link 81 and the cross arm 78 to be'lowered. The movement of the cross arm 7 8 is thereby imparted to the rods 68 and 69 through the collars 76 and 77 fixed thereto, and finally to the horizontal rods 66 and 67 which come in contact with the upper edges of the cross bars and 65. This downward movement of the horizontal bars will bring the cross bars to the horizontal or neutral position. If, however, it is only desired to swing the cross bars of one side of the finger board to neutral position to break the circuits of one set of electro-magnets and to repeat the operation of those on the other side, the operator will not in that case oper ate the lever 82, but will, for example, press down the finger bar 70, thereby bringing the horizontal bar 66 into contact with the cross bars 55 and 65 which have been operated to close the circuits on the red side, the other cross bars which are connected to the plungers closing the circuits on the green side not being affected thereby. This operation is possible by reason of the fact that as the finger bar is depressed and the rods 68 secured thereto are lowered, the collars 76 will separate from the end of the cross arm 78 and compress the coil springs 73 without any effect upon the cross arm and the other members, 71, 77, 69 and 74.

Fig.1 is referred to as'showing, in a diagrammatic disposition, the distribution of the electro-magnets in respect to the punch ing plungers, the electric wiring diagram and also a plan view of the finger keyboard or switchboard. It has been deemed only necessary to show the wiring diagram for the circuits controlling the first and second punching plungers of each head, as well as the wiring for the signals for the same, and also the wiring of the circuits controlling the large punching plungers for punching the peg holes. The wiring for the other circuits follow the same plan and their illustration is deemed unnecessary, the leading ends of these circuits merely being shown. In tracing out the circuit for the first punch of both heads, the operator depresses the first key 49 of the set upon the red side of the key-board and closesthe circuit leading from the feed wire 92 to the busbar 105, spring contacts 61, contact plunger 59, the wires 106 and 107, electroanagnets 21, wire 109, to theelectro-magnets 19, wire 110 and wire 111 to the feed line 96. One of the red lights 94, corresponding to this circuit is connected in shunt therewith, across the wires 106 and 109 leading to and from the electro-magnet 20, by the wires 112 and 113. In following the circuit for the first plunger upon the head 1, only, the operator depresses'the key 50 of the set upon the green side of the finger key-board and closes the circuit leading from the feed wire 93, to the bus-bar 114, spring contacts 62, contact plunger 60, wires 113 and 109, electro-magnets 19, wires 110 and 111 to the feed line 96. The green light circuit corresponding to this operation leads from the bus-bar 114 to the light 95 and thence to the wires 117 and 118 to the movable contact 99 mounted upon one of the locking rods 13, stationary contact 100, wire 119, movable contact 97 mounted upon one of the locking rods 11, stationary contact 98, wires 120, 110, and 111 to feed wire 96. From the above, it will be noted that in the case of operating the circuit from the red side of the finger board, the electro-magnets 20, corresponding to the first punch hole on the head 2, as well as the electromagnets 19 corresponding to the first hole on the punch head 1 are in circuit in series and are both operated whereby the first plungers of both heads are locked so as to perforate the first hole of a row in each of the cards 33 and 34. In the case of closing the first circuit on the green side of the finger board, the corresponding red circuit cannot be closed, but the green circuit is closed through the electro-magnets 19 of the first punch of the head 1 only, thereby punching the first hole of a row in the card 33. The other circuits are controlled on both sides of the finger boards in exactly the same manner as described above. For the purpose of operating the large punchi plungers for the peg perforations, the ad itional switch operating means, provided at the end of the switch board is operated upon either side of the board in a manner similar to operating the other circuit closing means described above. In this case the circuit leads from the feed wire 92, to wire*90, to either bus- bar 105 or 114, through either plunger contact switches 121 and 1.22., wire 123, electro-magnets 45, wire 124, electro-magnets46,

wires 125 and 111 to feed line 96. This cir-' cuitclosing means is operated only at intervals occurring between thepatterns upon the cards, and it is optional as to which of the switches 122 is operated.

For the purpose of directing the operator in the manner of pressing the finger keys 49 and 50 to produce a desired pattern, a chart has been composed from which the combined -space indicating no operation of any key.

The vertical columns are numbered from 1 to 16, corresponding to the'first to the sixteenth punch holes in both heads 1 and 2, as well as to the first to the sixteenth finger keys of each set on the'finger board. The horizontal rows represent cards, the first row of holes for the first set of cards (here a pair) being indicated in the first section of the left hand side of the chart as shown in Fig. 1. The second row of holes being represented by the first horizontal row in thesecond section of the chart and the third row of holes represented by the first horizontal row in the third section, and so on indefinitely for the number of rows that may 7 occur in or be chosen for acard. After the peg holes are punched and the card strip moved a suflicient distance, for starting a design upon a second set v of cards the second horizontal row of thechart is read from left to right, each section in said row representing as indicated above, a row of holes in the cards.

For example, in reading the chart shown,

theoperator will for punching the first rowof holes for the first pair of cards, press th keys from 1 to 16 as follows: Red, 1, '2, 4 and 6, green 7, red 10,12,15,16;second row green 1 red 2, green 3, 5, red 6, 7, 8, 9, green 10, red 11, 13, green 14, 15, red 16, and so on for. the succeeding rows, until the length of a set of cards is completed. In perforating the second set, of cards, the operator mounted upon the table 1124.

reads upon the. second horizontal row from left to right, similarly to the manner indicated above. l

In addition to the above means it frequently occurs that a pattern of-more or. less uniform orsymmetrical design is to be controlled, and in order to facilitate operating the circuits therefor and also to save time, I haveprovided at each side of the finger keyboard supplementary circuit closing means, as is shown in the simpler form in Figs. 2, 5 and 6 and in a more elaborate form in Figs; 9 and'lO.

In the form shown in Figs. 2,5 and 6 the supplementary circuit closing means comprise pivoted supports 126 and 127 The upper ends of the supports carry laterally slotte'd beams 128 and 129 in the slots of which slidablyrepose the comb bars 130 and 1310f electrically conducting .nretal, suchras brass, copper, or the like. These comb-bars are provided with lateral teeth like :contact' points 132 and 133 'adaptedtojsuccessively contact with the shanks 61' andta of the spring contacts 61 and 62; respectively as the combba'rs are moved; longitudinallyiin the grooves or slots of the beams 128 and .129-

These contact points are distributed along the comb-bars in certain spaced; relation-determinedupon the relation of the circuits to be controlled. In the form shown in: Figs. 5 and 7, the contact points are arranged to contact with thefirst, fourth, seventh, tenth, thirteenth and'sixteenth shanks 61 and 62, in the first circuit closing position of :this particular comb-bar. In the second circuit closing position this form of comb-bar, closes the circuits forthe seoond, fifth, eighth, eleventh and fourteenth shanks 61" and 62?, and so on indefinitely.

In Fig. 8 the Contact points are shown as arranged in the order to close the circuits of the first, seventh and-thirteenth shanks in the first circuit closing position; thesecond, eighth and fourteenth shanks in the'second position; the third, ninth a'nd fifteenth in the third position, and so forth), The operations described will produce a pattern effect termed a twill; and shown,.for the comb- 'bar of Fig. 8, in the design chart of'Fig. 11, the symbols w showing the form of twill produced. If. in operating these combbars,

that on the red side ,of'the switch-board be successively moved in the direction from the first to the sixteenth shanks 61and that on the green side be simultaneously moved from the sixteenth to the firstshanks 62', the combined pattern effect will be of a honey-comb.design as is shown in the combined arrangement of the symbols w and 0,in-the design chart shown in Fig. .11.

The shanks 61 and 62? asis clearly shown in Figs. 5 and 9, are embedded in the, insulating material of the key-boardso that the faces of both the shank pieces and the insucomb-bars so that the contact points will lie between the shanks 61 or 62, or even beyond the same at the end of the switch-board, has the effect of opening all of the circuits of the comb-bars so positioned.

The springs 134: and 135 are secured to an end thereof to the supports 126 and 127 and at the other end to fixed uprights 186 and 137 rigidly secured to the table24c. These springs serve the purpose of constantly urging the beams and comb-bars'toward the shanks 61 and 62so that the contact points thereof shall bear with the pressure requisite to make a good electrical contact between the points and the shanks, as the bars are successively moved, in the manner described above. a d

In the beamsare also provided recesses in which are disposed springs 138 and 139 the ends of which resiliently bearagainst the rear edges of the comb- bars 130 and 131 and the centers of which are suitably securedtothebeams as by screws140 and 141. These springs also aid in pressing the combbar-contact points against the shanks 61 and '62, {andalso compensates for variations in the widths o'f'the bars used as well as for wear thereof.

The bars are also-each provided with perforations or depressions 1 12 with which spring detent means 143 ofany suitable type may cooperate to temporarily lockthe bars in their successive positions but not with such engagement astoprevent movement of the bars by hand. V i

At the end of the beams 128 and 129 are provided contact plates 144 and 14-5 adapted to engage with the rear edges of the combbars, whereby electrical current leading in through the leads 1-16 and 147 may be conducted tothe combbars 130- and 131 for the purposes mentioned above. I

In operation, the operator -lowers the beams 128 and 129 about pivots'ot the supports and places in the slots thereof a set of comb- bars 130 and 131 and the beams are then permittedto swing up to position,

under the influence ofthe springs 134; and 135, where the contact points of the 'coml bars are pressed against the surface in which the shank contacts are embedded. The

bars may then bemoved longitudinally in the beam slots to present the contact points to the shankswhereby certain related circuits maybe closed. If the type of bar shown in Fig; She used, the first, seventh and thirteenth circuits, on the red side of the switchboard, will be closed as reprcsented by the symobls w in the lower row of the design chart shown in Fig. 11. On

moving the bar to the next position the second, eighth and fourteenth circuits will be closed, and thence accordingly for the full range of movement of the bars. This will effect a twill as represented by the symbols as only. If, however, at the same time the bars on the green side be operated in the reverse direction, as from the sixteenth to the first circuits, at the same time as the red side bar is operated, the combined effect will be that shown by the arrangement of the symbols 00 and 0 in Fig. 11, which'is called a honey-comb pattern. If, however, the comb-bar tor the green side he started at an advanced shank contact, as for example at the fourth rather than the first, when the comb-bar for the red side is started at the first shank contact, and both are moved in the same direction, the combined effect obtained is shown in the chart of Fig. 12, which is a twill pattern. It on the other hand the comb-bars on the red and green sides are advanced at different rates the pattern lines of one will cross the other and, therefore, produce a satin effect as shown in Fig. 13.

The charts in Figs. 11, 12 and 13 are shown more for illustrating the type of design or pattern ett'ect obtained rather than the chart from which the operator reads. The chart from which the operator con-' trols the operation of the comb-bars is in fact similar to that shown in Fig. at but the designs shown in Figs. 11, 12 and 13 are arranged to more clearly shoe the resultant relation of the design points controlled.

The device shown in Figs. 9 and 10 is in all respects the same as that shown in Figs. 5 and 6 with the exception that a plurality ot=c01nb-bars 180 and 131 may be plaierl in eachbeam and the beams are provided with mechanical means whereby the bars may be moved definite distances in one direction or the other by the simple manual movement of said means.

These beams are, therefore, provided with longitudinal slide ways 148 and 119 in which are adapted to slide the slide-bars 150 and 151. are pivotally attached tl e spring pressed pawl-hooks 152 and 153 adapted to engage with the teeth 154C and 155 provided upon the rear edges of the comb-bars. The other ends of the slide bars are provided with finger buttons 156 and 157 projecting upwardly above the top of the beams. Springs 158 and 159 are nested in the ends of the slide-ways tor operation agalnst the slide bars to return the same to initial position,

when the same have been manually operated as indicated above.

When it is desired to reverse the movement of the comb-bars, the pawl-hooks 1-32- and 153 may be thrown out of engagement At the free ends of the latter by the arm' 160 or 161 of the release levers 162 or 163 as the latter are manually moved by the handle portions 164; or 165. Detent projections 166 carried on each lever are adapted to engage depressions 167 on the beams for the purpose of holding the levers in their alternate positions. When the pawlhooks are thus dis-engaged from the bars at vone end thereof, the release lever at the other end may be operated to permit the reengagement of the pawl-hooks 152 and 153 with the teeth 151' and 155 and manual manipulation of the finger buttons 156" and 157 will be effective to move the bars as in the first operation described except in the reverse direction.

It will be notedthat the arms 160 and 161 of the release levers are provided with detent hooks 168 and 169,;engageable with the teeth 154, 155, 15 1 and 155 of thecom b bars to act as detent pawls therefor. When the release levers are operated tojdisengage the pawl-hooks these detent hooks will also be simultaneously disengaged ,7 1 The circuit jleads -1 16 andf1i7 are connected to the contact plates 1451: and 1 15 which are suitablysecured tojtheend of the insulating material of the switch-board and which also engages with the front edges of the shanks of, the comb-bars, as is clearly shown in Fig. 9. g V

The operation of this form of supplementary circuit closingmeans is similar to that shown in Figs. 5 and 6 and described above withthe exception that the movements of the comb-bars are accomplished I by manually movin the finger buttons 1 56, 157, 156- and 15 The amount of movement is half of the distance between the shanks of the spring contacts, so that two movements of a finger button will be required to move a contact point on a combbar from one of the shank contacts to the next. A single movement will, obviously, carry the contact points to insulated points between the shank contacts thus opening the circuits. In;order'that the'finge'r buttons may have theproper amount of movement stop- pins 170, 171,1?0 and 171. are driven into the beams 128 and 129 at proper points to limit such movement. I I

The leads to the contact plates 14A and 144:- .on the red. sideare connectedto the feed wire 92, while the leads to the contact plates 14:5 and145' on the green side are connectedtoithe feed wire 93. The; circuits on the other side of the shank contacts are completed in exactly the same manneras hereinbefore' described in connection with the wiring diagram shown in Fig. 1.

Where, however, the design or thepattern :to be produced involvesthe operation of nearly all of thepunches, a few holes only in each set of cards being omitted, it has been found? that the punching operation may claim as new and desire to secure by be carried out with a great saving of time and with greater facility by first closing all of the circuits on one side or the other of the switch board by depressing the finger bars or 71 to the full extent as shown in dotted lines in Fig. 2 whereby all of the switches onthe red or green 7 sides respectively are closed. For the purpose of preventing certain of the punches on a side from operating it is then onlynecessary to open the corresponding individual switches on the red or green side by pressing the keys 50 or 49 respectively on the opposite side to chines for the manufacture oflaces, nettings and similar articles, are also as fully adapted for use with any machine, controlled by jacquard cards, and used for the manufacture of other articles, such as carpets, upholstery materials and similar products.

By the above described invention it has become possible to perforate cards with a larger number of holes than heretofore and to also perforate similar. patterns simultaneously in a plurality of cards, and therefore, whilevone formor embodiment of the invention hasbeen disclosed it is to be understood'that the invention is not limited particularly thereto, but comprehends also the idea of perforating any number of holes simultaneously in an indefinite number of cards as well as the perforating of additional holes in any of the cards as may be selected, andit is to be further understood that many changes in this invention are fully contemplated as may be within the aim and the spirit of the present invention and within the scope of the appended claims.
