In the present' instance my lnventlon embodies certain broadly new features but in the application'V ofmy invention I have emf ployed many of the elementslwhich form the subject matter of U. S. Patent No. 627,256, as a basis for the machine and I describe my ivention as applied to such general construction, to' simplify the present case,- thoughit is to be understood that the resent mechanism and thegeneral form othe machine 'to which the same isapplied may be overcome this objection whether employed :in the construction above set forth or some ijother, by providing mechanism wherein the variedwithout depart' from the spirit and scope of my'invention. In the com struction shown in said U. S. patent,wh1ch is-the best structure so far knownto me there l .are certain elements for perforating a paper strip or jacquard card, which arearranged to produce Vvarious perforations in tra-nsverse alinement, each transverse l-'ine of perforationsrepresenting one stitch of the em* broidering machine when the' card is used in the iacquardof an embroiderin machine. The tambour frame o f the embroi eringmachine is moved in relation to the needles after each operation of the needles to form the stitch and in the jacquard most comments of different units are combined toproduce vthe proper'iinal movement in the tambour frame. In the card punching.' machi-ne shown in said S. patent there are several (four) stitch determining elements which aetuate perforatn'g elements and eachstitch: determining element serves to' select from sgroup of punching elements whereby the location of the perforations inV ea transverse 'row ofthe card 'are determined and the location of determines the' stitching position. of the tambour frame of the embroideringmachine.

elements consist of drums havin v,pins extending from the periphery Whic pins are arranged s irally thereon, and the spirals run reverse y on the opposite halves of the drums. These stitch determining elements are operated by the o erator of the machine through mechanism escribed in said patent and by changing the positions of these various drums t ey place the Various punching elements into operative condition for perforating thel jacquard card and when the drums have been properly positioned for a stitch the punching mechanism isset into motion and the card is. perforated.. In such structure, however, the machine can not be set into operation to perform the punching operation unless the stitch detcrmlnin elements are locked and the stitch determlning elements are locked until the punching op-.-

.eration is completed. It is obvious',y therefore that the machine must start, punch and come to a stop again before the stitch de- .tel-mining; elements cany be reset for a new stitch, thus making the speed of the machine f limited.

It is the object of my present invention to operator can proceed to' lay out a new stitch before the machine has performed the punching operation -or at least before the p'arts come to a complete stop, so that by the time the punchingis completed the operator will have positioned the stitch determining elemen-ts and will be ready to set the machine into operation to perform the new punching operation. If the operator be4 skilo @ful he can,vby `quick action in positioning g the determining elements, cause the machine to operate practically continuously, that is,

without'letting the shaft 'and-its cams come vention I make it possible toi-slet the machine so that it will run continuouslyV so that the operator will be required to position the determining elements before the punching or ratherl before commences the next one,y thereb up the s eed of the op'eratcu'.-4

placed by the stitch determining elements until the unching is completed and by automaticaily releasing the stitch determining elements when the retaining mechanism has entered into action, so that the stitch determining elements can be reset ready for the next operation. By the time the punching mechanism has completed its function the punching elements wi l be again brought into'. condition to be acted upon by the determining elements which latter were newly ositioned as describedL YI employ proper ocking mechanism to insure accuracy, ut the mechanism is only locked for a brief 15 period. The locking mechanism forms one of the principal parts of the present case, as wellas the mechanism for releasing the determining elements and retaining the punching elements during the punching operation.

A full embodiment of my invention in the preferred form will be apparent in the de tailed description hereinafter.

In the drawings forming a part of this a plication, Figure 1 is a ongitudinal seetion throu h the punching machine withthe parts in t eir starting position, Fig. 2 is a similar view with the parts in a different osition, Fig. 3 is a horizontal section showing the starting and stopping mechanism, Fig. 4 is a detail view showing oneof the leveractions, Fig. 5 is a longitudinal section showing the stitch determining mechanism and punching mechanism, Fig. 6 is a similar view with the parts in a different position, Fi 7 is a similar view with theJ parts in a di erent position, Fig. 8 is a detail view showing certai lever actions, Fig. 9 is an elevation of part of the punching mechanism, Fig. 10 is an elevation of one of the punch selecting slides, Fig. 11 is a similar view of another slide, and Fig. 12 is a plan view o f one of the arts.

I will first describe that branch of the mechanism which relates to `the control of the stitch determining elements which is shown more clearly in Figs. 1 to 4. `Herein I have shown the bed plate 1, on `which-rest the side plates 2, and the latter serve as supports for. the various shafts and 'working parts on the lower 4 part of the machine. The punching block and unches are only indicated in dotted'lines in these views as they- ,are fully shown inthe other views of the drawin s and they will be hereinafter fully descried. It maybe here stated that the machine shown in the U. S. patent referred to` herein may be employed except'in so far as parts of the saine are superceded by the device herein and as'such construction'is fully described Vin that -patent I will refer to only such parts' of the complete machine as may be necessary to teach the application gf m invention. In the constructiony re- 65 er to in the said patent there .are certain-drums e' e2, e', 0*,carryin r the punch operating elements ins) e, w ich are arranged 'spirally on tiie drums in a certain way and these drums are revolved by thc 'o erator in connection with certain mechanism by which the operator is able to follow the movements onl the pattern; and these drums, which I shall herein call the stitch determining elements, as well as the mechanism for operating them is full-y set forth in said atent and the same may be and preferab y are, employed in the present .construction. In the present construction these determining elements are carried upon the shafts as shown in said patent-'and are similarl operated. The mechanism for control ing the operation of these elements, or

rather 'locking them relative to certain other mechanism is here new.

The shaft 60 which is part of the stitch determining mechanism is provided with a gear wheel 58 which moves with the shaft, and therefore with the stitch determining mechanism. There is a stud 63 arranged near the gear wheel on which is fulcrumed a lever 61, the upper end of which carries a .dog 59, which is so positioned that it can be thrown into or out of engagement with the teeth of the gear 58 and thereby prevent or permit the operation of 'the shaft 60. *It is through this dog that the stitch determinin elements are prevented from being operated untilcertain conditions in the machine are present. The lower end of this lever 61 carries an engaging pin 62, while the upper end has an extension 73, which is provided with a pin 74. A shaft 21 supportsan angular lever 75, 96, the forward end of which has a slot 75* in which the pin 74 engages, and by .means of which engagement certain movements are imparted from the lever 61 to the lever 7 5, 96. The main shaft 18 0f the ma- -chine carries certain o erating cams, one

of which is numberedV 6, which is-shown more fully in Fig.'1', etc.; and this cam carries a gear crown 77 on its periphery the urpose 4of which will appear.4 The shaft' 18 is adapted to be driven from a source of power and b means of suitable controlling mechanism the shaft 18 may be' started or stopped by connecting or disconnecting the shaft 18 with the sourcel of power. In the present showing the pulley 101 on shaft 102 lfurnishes the power and by means ofa lever' theshaft 79 is thrown into orV out of en gagement with the ulley 101. Ihavefsh'own the shaft 102 provilded with one element 101 of a cone clutch-and the shaft 79 which is adapted to be reciprocated longitudinally, is provided with the other element 99 of the cone clutch; and the whole clutch is incased in a shell 104 which has 'a flange 104which serves as a' brake for'the 'clutch ,element 99 and therefore for the' shaft 79. I have shown the shaft l79 -joui'naled in the blocks V80 and other.

atin 'force to the gear 77 and thus tothe and a spring 98 inter osecl between the block 81 and gear 78 ten sy tov force the shaft 79longitudinally in such a way astocause the clutch elements 101, 99, to `engage and thus revolve the shaft 79. So long as the aft 79 the ower from shaft 102 is imi parted throug the shaft 79, gears' 8 and 77 to shaft 18.

vOn the perpendicular shaft 82 I have il mounted a throwingoutlever 83,'the hub of which is provided with arms 84 and 85 .which straddlethe shaft 79 and. impinge the The purpose collar 100 carried thereon. of lthis lever is to force the shaft 79 in opposition to the s ring98 and b longitudinal displacement isengage the c utch elements v to stop the operation of shaft 18. The arm 86 of the lever 83 carries a contact nose V87 which is engaged by a controlling lever.

n the stud 88 I have journaled a lever 89, which 'is provided on its upper end with els in a groove 92 .of the oove cam 76, and by means of this cam the ever 89 is periodically rocked. There is another lever 94 which is fulcrumed at 93 to the lever 89, and one end 941 has a rocking contact with the lever 96, the spring 97, vtending to retain the lever ends in -contact with each The other end 94a of lever 94 has a pin 95 which is adapted to engage with the part 87 of lever 83.

Near the stitch determining mechanism lI have provided a Vbracket 105 which supports a stud106 and on this latter is fulcrumed a two armed trigger 107 which servesto release the lever 61, controlling the locking mechanism. This tri ger has an engaging shoulder 108, with whlch the pin 62 on lever 61 engages. A spring 109 connected to one end of the trigger and to the bracket 105 retains the trigger in contact with the lever i 61. The other arm of the trigger 107 is connected with means operated from the shaft 18 for causing the lever 61 to assume different positions independent of any action of some of the other elements. A stud 127 is :suitably supported in a bracket and serves as a fulcrum point for a lever 123. The lat- 1 terhas a, roller 129 on the pin 128 which roller travels in the groove 130, of a cam 131 on the shaft 18 and on every revolution of thecam 131 the lever 123 is twice affected i by the carni There is fulcrumed to the lever 1.23 an arm 122 which operates the shaft 63' on which the lever 61- is carried. The rod- 122 is passed through the end of an arm 121 which 1s secured on shaft 63, the same being the shaft which carries the lever 61 and the .pi n 126 retainsthese parts in this relation.

saaml 81 and its purpose is to transmit the'opersha t 18. The'shaft 79 carries a gear 78v which meshes with and operates l.the gear 77 s'ring 98 is free to exert its effect on the` s a pin 90, which carries a roller 99 that trav-l Between the lever 121 and the collar 124 is a spelral 'jspring V125 -whichI forces these two e ments apart. f

v On :1V-stationary stud 112 I have mounted a three arm lever 111; One end of this lever is connected with a rope 114 which serves to actuate the `mechanism and corresponds with the lstarting rope inV said patent and may be similarly connected and o 110fof this lever is so itioned that 'it will engage and trip thetrigger 107 forreleasing the latter.' The other arm of this lever 111, is connected by a rod '113, with afbar 120 and this in :turn is raised orlowered by the action of an eccentric 119. The latter is mounted onthe machine where the same may be easily operated bv ther operator turning the handle 118, and thereby the shaft 117 on which the eccentric is carried.V lThe pur ose of this will appear in thedescription o the operation of the device.

Before passin to the remainder of the construction I willdescribe'the operation of this part of the mechanism.

Let yit be assumed that the stitch to be recorded has been .determined upon and the pin drums suchlas e', e2, e3 and e4, in-said patent have beenpositioned, ready to operate through certain selecting elements, for punching thecard. The stitch determining elements being set and the present-mechanism being in the position shown in Fig.

1, the operator pulls the rope 114 in the di-v rection of the arrow to set the punching mechanism intooperation, `after which he lets the rope loose tov allow the parts to assume their first position. I will first de scribe the device as operating with the handle 118 set as shown in Fig. 1, wherein it is necessary for the loperator to initiate each punching operation by pulling the rope 114.

VWhen the rope 114 is pulled it rocks the lever 111 on its fulcrum, result-ing in the trigger 107 being rocked against the action of its spring 109, by the varm 110 of lever 111 and the result will be that the cam port-ion 108 of the trigger will be released from engagement with the pin 62 of lever 61. The rod '-122 is so positioned by the action of cam groove 130 on the roller of lever 123, that the rod 122 will be in its right hand position (Fig. 1) where the-spring 125 will tend toV force the arm 121 to the-right. llhile the pin 62 was in engagement with the trigger the dog 59 was retained out of engagement with the gear 58, which permitted the setting of the stitch determining elements as stated. Vhen the trigger is pressed by the arm 110 it leaves the arm 121 subject to the action of the spring 125 and as a result the arm 121 will be rocked, moving the shaft 63 and with it the lever 61, until the dog 59 is thrown into the teeth of the pinion 58. The stitch determining elements are now locked and can not befrepositioned for the rated. The arm next stitch until the dog 59 is releasedV from thevginion in the manner which will appear.

' idle. When the lever 83 isv freleasedby the rocking of lever 94 as above stated it will be free torotate suilicient to permit shaft 79 to be displaced. Upon the freeing of the lever 83 the spring 98 pressing against the gear 78 forces the shaft 79 in the directionV of they arrow, the gears 78 and 77 being inengagement with each other at all times. The movement of the shaft 79 longitudinally brings the clutch elements 99 and 101 into frictional engagement. Since the shaft 102 andhits clutch 'element are continually oper' ating, the shaft 79 will now be revolved and by reason of the gears 77 and 78 the move ment will be imparted to the shaft 18 which operates the punching mechanism.

When the vshaft18 rotates, the 'several cams carried thereby punchin 4 change 1n the locking mechanism. en the shaft 18 begins to turn the position of the punch locking slides will be 'retained by the mechanism hereinafter described, in the position necessary to erform the punching operation, but the stitch determining elements will be so aflected,.before the shaft 18 has proceeded farthat they need not remain ias set but can be returned to-be reset for a new stitch without waitin completion of theA punching operation.

Soon. after starting, thecam groove 130 will rock the lever 123 and therebyV the rod 122 will be moved to the left. .The engagement ofthe pin 126 with the arm 1'21 will then rock the -shaft 63 and lever 61 to disengage the dog 59 from the pinion 58. As the do is thus Areleased the operator can now procee to lay out the next stitch by reposirotate also, causing the tioningthe stitch determining elements by the mechanism described in the saidA patent. Vhen the lever 61 is thus rocked in a direction reverse to its first movement it also rocks the'lever 75, 96, and this in turn 'rocks the arm or lever 94 on its fulcrum 93. The

\ result .will be that the-pin '95 on the'lever 94 will bebrought again in the path of'the pin 87 on the throwing out lever 83. Whenv the shaft 18 is nearing thecom letion of its revolution theY camv 76 throug :the ve 92 will rock the lever 89,tof the le and since the lever -94 iscarried thereby and since the osition oflever 94.1is now such that the p1n95 isin the pathof-p'in 87the ins will been End lever 83 wildrocked back to its first operation and also causin a1 for the as the lever 89 rocks position. As it does so the arms 84, 85, will reciprocate shaft 79, compressing the spring 98 and releasing the clutch until the shaft 79 is no longer driven. The return action will engage the clutch element 99 with the flange 104l and cause'the shaft 79 to stop by a braking action. The mechanism is thus automatically stopped after each revolution of the shaft 18 and after the completion of one unching operation and will remain so unti the `operator again initiates an action. When the operator releases the rope 114 the actionof the spring 109 on the trigger will move its engaging part108 again into the path of the pin 62, ready for the second operation.

The machine automatically stops after each punching operation unless the o erator has been able to lay out the second stitch by the time the first punching operation is completedin which case he pulls rope 114 before the machine stops and it goes on to perform the second punching operation. If the machine is to be run continuously so that the 'operator will have to set out his new stitch while the punching is being completed the setting handle 118 is turned to the position shown in Fig. 2. The effect of this will beV to raise the bar 120 on the eccentric 119, thus raising the rod 113 `and rocking the lever 111 until the arm 110 presses the trigger out of the path of the pin 62. There will thus be nothing to engage the lever 61 at each operation and therefore it will be subject tothe effect of each movement of the rod 1.22 and as a result a new movement is initiated bythe time the last one is being completed and as a result there will be no stopping of the sha-ft 18 and the punching mechanism though the stitch determining mechanismwill be automatically locked for a brief period of each operation.' The operator will now be obliged to lay out the second stitch before the machine has completed the first and so on. In this way the machine will not have to stop after each punch and then be started againand the operator will be obligedy to keep up in his speed.

If the dog 59 should accidentally engage the top of one of theteeth of the pinion 58 no trouble will result, because the action of the rod 122 to the right is imparted through the spring 125 which, may be resisted.

AThe-next branch of my invention relates tothe punching mechanism and to its co- Should the do 59 engage on top of a tooth f the rod 122 an all the other mechanism will f operationwith the safety mechanism just described.

There is provided a punching block 4, disposed inthe machinerwhere it will haveV roper location with relation jto the punchmg elements." Above thev punching block I have provided a punching plate 5 anda pressing plate 6, between whichv the paper strip or pattern roll 64 travels and these plates are provided with'a double row of perfozations 61, 6b, which are in stepped relation, as` shown .in Fig. 12. Thepattern roll is fed from a suitable supply roll, under the roller 65,"over theJ roller 66, between the plates 5 and 6 and onto a roller 690m the shaft 70, and the feed rollers 67 and 68, interposedbetween the vplates 5, 6, and roll 69 serve to propel the paper intermittently For operating the feed mechanism as that lshown in said U.

For this purpose there is an angle met-a1 bar 8, the two flan es 8 of which have apertures for the reception of the rods 9 and 9a and the aperturesaline with the apertures 6a and 6", ments')c lie between the bar 7 and the lower flange 8a of the bar 8. The bar 8 is provided with an openpocket above the upper flange 88l for the engagement of the locking in the slides, and the bai' is supported above by links 11, which are hung on the end of a` lever 12. This lever fulcrums on a support 18 and one arm 14 thereof is provided with a Apin 15 carrying a bowl 16 which engages Vcove 16 of'a cam. 17 carried upon the main shaft 18, and by means of this ca m the lever-12, 14 is rocked twice at each revolution of the shaft 18 and the bar 8 is therefore raised and lowered twice.

and for each rod 9 there is a slide 10 arranged to engage the'rods above. I have provided automatic means for advancing the several slides when brought into operative relation therewith and there is mechanism whereby the stitch determining device first positions these vkslidesfor movement by said automatic-means, and there is other means whereby the slides are preserved in the position thus placed -untilthe punching 1s complete'L so that the stitch determining mechanism may be again operated without havingy to retain the slides in theirrposition by the determining mechanism during the punching operation.

There are provided two. cross shafts v and 47 which carry the push plates 4.6 land 53 by means of which the locking slides are reciprocated g. the plate 46 serving to engage fin the'slots 10c and move the slides 10, while the plate 53 enga es in the slots 10.b and re, y ciprocates the sli 10. The space 10d prevents the plate 46A from affecting the slides 10, so that the two sets of slides will be affected only by their respective push plates. The shafts 45 vand 47 lie above the slides and are. adapted to engage onlyfsuch slides of their respective sets as are raised into engaging position. The shafts 45 and .47 are periodically rocked from the main shaft 1.8, one yslightly prior to the other, so that the two sets of slides will be reciprocated successively for the purpose of bringing the f perforations caused by the two setsof punches in a transverse line.

The .device for rocking the shaft 47 cola` Vsists of an arm 48 secured to the shaft, which is fulcrumed to a connecting link 49 and the latter to a lever 5.0,v which fulcrums on a support 51. IThe other arm of the lever 5l carries a bowl 52v which travels in the 'groove 43l of a disk cam 44 carried on the shaft 18. Each revolution of cam 44 causes the lever 51 to be rocked, and the movement. is transmittedthrou'gh the link 49, and lever 48 to the shaft 47 which itV oscillates. The shaft 47 oscillating,l imparts through the push plate 53 a reciprocating.movement:J to such. of the slides 10 asare raised, moving' them first to the left so that the "rounded portions .10 will come overtheir respective punch rods and then back to their ,first position.

The shaft 45is rocked in a similar manner to the shaft 47 but the movement is in advance of that of shaft 47. There is an arm 39 on shaft 45, corresponding to the arm 48, and it is fulcrumed to a link 38, which connects with alever 40, rocking on a support 41. The other arm of this lever has a bowl v V operative relation with their push plates 46, 53, forms a novel. and important part' of the present invention. On-the stud 21 I have provided a rocking lever 22,- which carries' a roller 24 on .the pin 23 and this roller is retained in contact with a cam arm 26 on the shaft 18 by means ofa spring 25. Itwill be thusapparent that the lever22 is rocked at eachfrevolution of the shaft 18.

, The arm '22! on the shaft 21 is provided with 'a .plate 20 which is provided with as many apertures as there are slides 10 and 10 and through the's'e apertures rest the pins 19. These pins are preferably rivet shaped, with their heads 19 normally rest- -ing on the plate 20 and their shanks 19 passing through the apertures and below the plate 20, where they are actuated by theV stitch determining mechanism. The pins 19 are carried upwardly by the plate 20 and their function will be more clearly understood in the description of the operation of the mechanism. On the 'plate 20 there areears 27, spaced apart, which ,act as supports for the arms 29 which are fulcrumed 'thereto; and these arms 29 carry afsupportlng plate 30 which rocks on its supporting arms and which is adapted to engage'under the heads'of the pins 19 and retain them in an elevated position to preserve their position 45 when the stitch determinin mechanism is released. A spring- 32 whic surrounds the shaft .28, on which the arms 29 rock have one end engaging inthe shaft 'and the other against the arms 29, whereby the plate 30 will be retained in the position shown in Fig. 5 unless resisted. The plate 3Q -is provided with an upwardly extending arm 31 which is adapted to be engaged by an arm 33 for the purpose of tripping the late 30 to re- 55 lease it from engagement wit the pins 19. The arm 33 is carried on an arm 34 which rocks with the shaft 35 and this latter is o erated lby means of a bifurcated arm 36 willich straddles a pin 37 on the link 38, the` operation of which has been described.

As previously stated thereA is a pin 19 for each of the slides 10, 10, which rthe pins are adapted to raise into engagement with theirrespective push plates. These pins 19 are operated by the stitch determining mecha-l nism to select certain of the punching elements for operation.4 The drums '55, which have b een previousl, referred to. in the description of the sa ety mechanism are the same as the drums e', e, e, e4, of the said U. S. 70 patent and each has adouble set of pins 56 arranged 1n reverse spirals across their periphery, with a space L between 'the sets sufficient to permit the pins 19 to rest unaffected when the drums are in their normal' posi- 75 tion. The position ofthe parts in Fig. 5 may be considered the normal or starting position, wherethe pins 19 rest with -their heads 19l on the plate 20 and the plate 20 'in its low position. The drums 55 are operated 80 l by means of the mechanism shown 1n said .patent and the lockingv and controlling mechl amsm for the shaft 60 has been previously described.

With the parts in the position' shown in 85 liig. 5 they vare ready for a punching operation. As the shaft 18 commences to revolver the roller 24 will rise on cam 26 and the lever 22 will be rocked. This will move the plate 2Q upwardl raising the pins 19 above the 90 pins 56. T e drums 554 are nowv in such a position as will determine the next stitch, when some of the pins'will come under certain of the raising ins 19. The roller 24 now rides down on t e cam 26 and the rock- 95' lng of lever 22 will move the plate 20 downwardly. Those pins 19 which are over any of the pins 56 of the sttchdeterminin mechanism will remain in their elevate position, while those not engaged by the ins 56V will ride down with the p ate 20. en

the pins 19 arose with the plate 20-all the slides 10,l 10a were raised attheir rear ends and when the plate 20 descended those slides which are engaged by the pins 19, aifected by the pins 56, remain4 raised and the others descend with their pins 19. When the plate 2,0 descended, as just described, the pins 19 which were resisted by the pins 56 and held elevated, will resist thel `downward movement of the plate 30'on one edge and as a result the plate 30 will be tilted, rocking on the arms 29, in resistance to the springs l32; and when the edge of the plate 30 passes the 'heads 19* of the pins 19 theplate`30 will 115 be rocked back again into its former position. When 'the plate30tripped over the heads of the raised pins 19, it entered between the heads' -of the lower pins and the heads of the upper pins as :shown in Fig. 6,1120 thus ,preserving the pins in the position first caused by the pins 56. In other words it assumes the sup ort of the pins 19 which were engaged by tliie pins'56 so that if the latter are moved away for the laying out of V another stitch the condition of the selectin slides is preserved until they have performe their function. lThe stitch. determining mechanism need no longer be retained in the position set for this punch because the sup- .camco port of the raised, ins 19 is now taken nlp by the plate 30. In act, when= the plate 30=has returned as previou'sl described, the mecha-- nism for operating tlie returnI of the drums 55 to their normal or starting position has come into actionandret-urned them, such. mechanism being the same asy in the said U. S, patent referred to herein., From this time the stitch determining. mechanism is uns locked by the mechanismdescribed' in the first part of this case and instead of waitin for the punching operation to be complete the operator can proceed. to lay out the next `stitch by positioning the drums :5 ready therefor. He can not, however, mrtlate th1s next stitch until the operation now being considered has been completed, because of the protective system described.v v

Some ot' the pins 19 are now resting on tfthe plate Q0,v while others are held raised by the plate 30. VThose held up. are supporting their respective slides 1.0 or- ILO- 1n an elevated position, Whenthe pushf plate .53 will lie in the slots b of such slides- 10y as are raised; while the push plate llt'will'lie yin the. slots 10' of such slides. 10 as; are

raised. The reciprocation of the .slides is now possible. The lever 50 is' first rocked by 'the action of cam 44 on'its bowl, Tand yas a result the movement will be transmitted by the link 49 and lever 48 'to the shaft 47 and push plate 53. This willmove the selectcd slides 1() forward, when their rounded portion l()e is over the tops of their respective punching rods 9. The first lrise of the cam groove 16i of cam 17 will -now operate on the bowl 16 to raise the lever 14, depress theV opposite end 12 and likewise the link'll and bar 8. The punching bars 9 which are locked by their slides 10' will be forced through the paper 64e, while those vnot aff' fected by their slides will rest upon thesurface of the paper and will not pass through it. Upon the return movement of the bar 8' the rods which perforated the paper as well the others will be raised again and the paper feed mechanism will operate to move the paper along sutlicient to bring the pertorations just made, in the transverse line ot the advance punch rods 9". The mechanism tor this is preferably the same as in saidv ll. S. patent and the purpose is the same; That is, the transverse rows of perforations can be placed closer together', with some ot' the perforations overlapping others, which could not be done were all the punch rods in one row. The slides 10, which were advanced for the operation described are' now returned by the return operation of the push plate 53. As soon as this takes place` the cam groove 43 acting on the roller 42, rocks the lever 40, moving thelink 38 and thus the lever 39 and shaft 45. This action moves the push plate 46 and advances such v of the slides 10a as are raised,forward, and

over theirfrespectivepunch rods 9* similiar to the action of thel revous. push" plate.` The bowl 16 willnow E second rise of the camgroove 16'l andthe ba-r S'will be depressedagain. `This time such punchl rods 9A as are-locked by their slidesV 19 will be forced through. the paper and byreason of. the repositioning Yo" the latter the new perforations will come in line withvthe. first mentioned perforations.

The bar 8. will; now return the punch rods. As the lever 40 was rocked to move the slides 10-IL forward theV pin 3'? on link 38, rocked e acted upon by the the lever 34, carrying the rod 33 up and.y

awa-y from the. arm. of the .plate 30. Uponl the return movement ot theA lever 40i and' its associated parts the rod 33 will trip 'the arm 31 and release the plate 30 from the heads 'of the raised pins 19, when the latter will return to their 'lower position andthe machine will be ready for the next succesf- Y sive' stitch, I'fl the stitch determining elements havebeen repositioned by this timel` `and the starting mechanism initiated the previously described .operations .will be repeated without any cessation. Otherwise the shaft'l'will come to a stop and will re.- man there until lthe next operation is ini. tiated by the mechanism described herein,

From the above it will be apparent that the mechanism. is safe and effective, but

- greater speed and increased work -are possible. The locking4 of the stitch determining mechanism takes place as soon as the machine operation is` initiated, but instead ci remaining locked until the entire punching is completed the stitch determining mecha,-

lnism lis unlocked automatically as soon v-as l the support of the pins 19-which have been raised by the, stitch determining mechanism,

has been taken up by the plate 30. ln this way. the stitch determining mechanism.,

`free soon after the punching operation is initiated so thatthe next stitch can be laid out while the punching is being completed.

While I have carefully described in detail one form of mechanism embodying. my

invention I am notV limited thereto, as the broad objects of my invention permit of changes m the mechanism by which -it vis Kcarried out.
