To wllwkom #may concern.'

Be it known that I, JOSEPH A. GROEBLI, a

- citizen of the United States, and a resident` of the city, county, and State of New `fork, have invented certain new and useful Jacquard-Card-Punching Machines, of wnich -order to produce the desired design upon thefabric. In' the machines so far used for i f ing mechanism and initiating the operation such purposes,A certain combinations mechanisms are operated to produce a sub- ',stantiallyV universal movementof the tamhour frame within its limit of movement; and in order to operate the tambour frame, the`jacquaid embodies devices for producing movements of certain units in extent and by variousl combinations' of .t-hegunits,` the many positions of `the tambourframe are I controlled. The jacquard itself -is controlled by means of 7a card or patternroll in the form of a strip of paper, in which are i provided various perforations, the positions .the above purpose,- or for operating special and relations of'which control the'operations of the jacquard. The perforations `for controllingv the jacquard movements have generally been formed in transverse rows acrossthe card or pattern roll. It is with machines for providing the ljacquard card with the perforations, whether they are for function mechanism in the jacquard, that my present invention'has to do.

...In U. S. Letters Patent issued to me, and numbered 627,256, I have shown one form of complete mechanism for perforating j acquard cardsnln that machineI showed certain elements for pcrforating the card, slides for selecting and locking the punches, means for moving the slides, and certain -devices for determining the stitching position, which latter mechanism served at each operation of th`e machine toy control the movements of the slides which madethepunching elements operation. that the work of the operator consists, prinoperative,and through such control the positions of the perforations on the jacquard card were determined. In that mi e certain operations must take place in a fixed relative order. That is, the operator first positions what I prefer to call the stitch determining mechanism, after which he -inltiates the operation of the main shaft of the punching machine, to set the punching mechanism into operation, by pulling a startinfg` rope. When the .punching mechanism is' initiated, the stitch determining'mechanism is automatically locked so that no changecan take place therein until the punching operation is completedpvhen the stitch determiningmechanism is unlocked to permit of its repositioning for the next p'uncliinggf It will therefore be apparent cipally, in positioning the stitch determinof the punohin mechanism, 'after which he can not proceed upon the'next operation unv'til the punching mechanism has completed -its operations and the lstitch .determining mechanism hasheen released; and in this way the operator' is moreor less restrained in the speed 'of his work. f

The object of my present invention is t0 increase 'the' speed of operation of the punching machine, by. making it possible,`v

for the operator to work continuously, ,that is, without having to wait, after setting the rstitch determining mechanism in proper position, for the punching operation to becompleted.- But instead, permit the operator to position the stitch determining mechanism as fast as his ability will permit, andvwithout any inactive interim. I therefore increase the output of the machine and,y`

increase theamount of work which the operator performs.' I accomplishthis by providing plural mechanisms for selecting and locking the punching elements, only one of which can operate at a time; and I preferably opera-te both sets of selecting` mechanisms from the same stitch determining' mechanism, thereby making' the whole machine simple in its construction and'opeifa-v tion. I employ means for automaticallyand alternately connecting the .stitch determining mechanism. with the punch selecting -and locking mechanisms, so that they. operatealtcrnatelyto.produce the desired result.A

When one set of punch selecting and locking devices has been actuated by the stitch determining mechanism, the machine proceeds to perform the punching operations; and while so doing the operator can proceed to lay out the next succeeding stitch bysetting the stitch second or inactive punch locking devices.

'flien, when the first punching operation has been completed and the irst set of`locliing slides have been returned, the second set will be ready to perform another selecting` and locking operation without any delay, and ithe irst. set will be in condition to be selected by the stitch determining mecha-r nism. By means of this alternate operation the work et the operator can be continuous,

as he will 'not have to wait Jfor the machine" to complete one of its operations, and'he can set the stitch determining mechanism as tast as his ability will permit.

I also provide means whereby the punching mechanism may be set to operate continuously instead of`stopping after each ment not only forms a part of the complete conibination,` but it is also susceptible of separate use,l either on machinesnow in use, or on machines which 'embody all the features of the present invention.

Fig. i', is an elevation thereof, 8, is a diagrammatic view showing the operation of the locking devices on the gear, and Fig. 9, is a similar view further illus- (rating such operation.

l prefer to embody the present invention in a machine of the type shown in my said Letters Pat-ent, #627256, as most of the mechanism in that patent can be used in the nak'zhhine of my present invention. Inasmuch as it will simplify this case to refer to that patent and the machine 'therein de` determining mechanism and,l thereby selecting the necessary slides inthe to such patent. It is to be understood that the punching machine may be and preer-.

ably is, constructed in accordance with that patent except wherein the elements shown in the present drawings are intended to supersede corresponding elements in said patent. I do not wish it to be inferred, however, that my present invention is limited to use in a machine of the type referred to.

In the Letters Patent referred to, I have shown a complete mechanism for punching jacquard cards, including a pointer for movement over the design, placed upon the board, mechanism which positions the pointer, and transmits its movements to certain mechanism, which latter I shall call the stitch determining mechanism, and selecting and punching devices. The stitch determining mechanism determines the location of the perforations on the jacquard card by selecting certain slides, at each operation, which slides make their corresponding punching elements operative. The entire mechanism of that patent may be used `down as far as, but not including, the drums which select the locking slides and from `there onvarious new mechanisms are em- Iployed to produce the new results. In said patent I have shown the stitch determining elements as consisting of revoluble drums, e, c, c2, and e3, each mounted on a separate shaftv or sleeve and independently revoluble about their axes; and these drums respond to the operations of the mechanisms operated by the opera-tor in connection wit the pointer. These'drums are normally retained in an intermediate on inactive position, and are independently revoluble in either direction from the normal position. These drums each have pins projecting radially trom their peripheries, and the pins are arranged spirally on the drums, they being arranged in reverse spirals on either side of the normal or inactive point ofl the drums. The punch selecting slides are adapted to be positioned by these pins, and the particular slide of a group to be selected, will depend upon the'position in which the pin drums e, e', e2, and.c3,are placed. These pin drums are utilized in the present mechanism, but instead of four in this form of machine) I emplloy say eight, arranged in pairs of two eac In the drawings herein I have shown the drums l, and Q, which have pins 3,4, projecting from their periphery and these pins are preferably arranged in all respects like the pins on the drums e, e', e2, and e3, of said patent. The drum 2 is mounted on a shaft 5, which is journaled in the side plates G, oft-he jacquard boX, in any suitable manner; and the drum l is mounted on a shaft 7, preferably on a horizontal line with the i shaft 5.V r-lhese two drums. are duplicated;

as many times as,v may be necessary for the punching machine construction to which they are applied. I n aconstruction such as that shown inmy said patent, there will be four of theidrums 1, mounted side by side, and there will be four drums 2, arranged side by side. These pin drums are not opera-ted directly, but through means With Which the drums 1 and 2may be alternately connected. I provide on a shaft 8, a gear 9, which is duplicated as many times as may be necessary, and ina machine of the type`herein referred to there will bef two such gears 9, Which are mounted on the same shafts and sleeves as the gears Q23, ofl my' said patent', and are 'operated 1n thel same manner'.

rIhe gear 9, is adapted to slidel on the shaft 8, and I provide a stud 10111, in an arm 102, secured to theshaft, Which engages with a hole in the gear 9, so that the gear will have a longitudinal movement on the shaft, but will be revolved therewith. rl`he Agear 9, is so located that it can be moved on the shaft 8, for the purpose of throwing it into mesh with either the gear12, om shaft 5, or'with gear 13, on the shaft 7, being the same shafts on which the pin drums are carried. The gearsA 12, and 13, are preferably arranged in staggered relation, that is,-the two sets are not in line with each other. "Iheseveral gears` 9, are

revolved to the right or left, the same man' ner in which the gears C23, are revolved in said patent, and through this movement the selection of the particular punches is con? vtrolledpand, therefore the movement to be gears 9., and the mechanism for controllingl used.

aimparted to the tambour frame by the jacquard in which the pattern roll is afterward That is to say,',the` location of the several perforations on the jacquard card is determined by the rotation which is given. to the gears 9, as will be apparent hereinafter; and I therefore prefer to refer to the their operation, as the stitch determining mechanism. l

I have shown a punching block 14, which is mounted on the base 15, of the-.punching machine, and this block is preferably the same i-n all respects as the punching block in my said patent. Likewise the plates 16, and 17 between WhichA the pattern roll or card is intermittently fed, are the samefI prefer to employ the two rows of punches 18, and

19 arranged in staggered relation, one rovvv .slightly to the rear of the other, as in mysaidpatent; and I prefer to provide the same power means for the punches as in my said patent, but the devices for locking them are different. The punch rods- 18 and 19 arc provided with enlargements 20, which are engaged by the supporting plate21, and above these enlargements I provide a bar i225* the rods 18, 19 passinghthrough both bars the same as in the said patent.. \'I`he the machine, .preferably bythe same mechanism as that used to operate` the punch block 1, in my said patent. In fact, the arrangement of the punches and theirv operation are the same as before, but the devices forselecting and. locking are differently constructed and operated.

The devices for selecting and locking the punches are as follows 1 As previously stated, the drums 1, and 2, are provided. with peripheral pins 3, 4, arranged in the' manner shown in said patent. For the drums 2, there is a ,rocking plate or bar 2%, which is carried on the ends of arms 25, the latter being mounted on a shaft 26. The bar 24, is

move up and down relative to the pins.

This arrangement.v is somewhat similar Ato the bar I and pins z', of my said patent.

There is a Areciprocable slide for each pin 28, arrangedpreferably above vthe latter, which slides are adapted to be selected by the pins 28, and therefore by the drums 2. The slides 30, are engaged by certain of the pins 28, while the slides 31, which are arranged side by side, and alternating with the slides 30, are engaged by pins 2S, alternating `with those which engage the slides'30. Y Y

The slides 30 and 31, are adapted to operate certain punch rod locking members insucha manner 'that the selected punches will be made operative, but in vsuch a manner that other selecting mechanism can operate upon the punch locking elements, as Will be apparent. For each slide 30, there is a locking element, consisting of a plate 32, which is adapted to -be reciprocated horizontally in the slots '3.3,' of the punching frame 23, while for each -slide 31, there is a similar locking plate 32, in line :therewith i The plates 32 'havea recess .35, in their lower guiding support 36 and are adapted' to 'cngage the ends of plates 32, for the purpose of .moving the plates tov the left in Fig. 1; but .their return is preferably effected by a separate e1ement,.so that the plates 32, may

be operated when the slides 3() and 31 areV land 412, with which the oscillating plate 13,4

on the shaft ist engages, to reciprocate the slides 31 back and fort-h. The slides 3() and 31 each have their separate reciprocating devices because their time of movement", is not the same. "The plat-e B19/is so arranged .that it will engage the projections 37 and 88 on the slides 30, but will not operate upon the slides 31: While the plate 43, Will only operate on the projections 41 and 4:2 of slides 31 and will not operate on the .slides 30.

, In front of the plates 32, I have arranged a plate 45, which is carried on a shaft- 4-6, and the oscillatory movement of this plate serves to return the slides 32, periodically, after cach operation: and this will occur twice for each row of perforations placed upon the card, as only half the rovvr of per* forations is made at one time, by the selected punches of one row.

After each operation of the drum 2, it is returned to its normal or intermediate position by mechanism similar to that used to return the drums e, e', e2, andV e3, of my said patent, but the time of operation will he changed, as will be apparent from the subsequent description. On the shaft 47, I provide an arm e8, on which is fulcrumed the upwardly extending tongs 49 and 50, `which straddle the shaft 5 of the drum 2,. each operation of the drum 2, in either direction from the normal, the tongs 4.9, 50

are reciprocated, and upon their downward movement eitzer the tong 49 or the tong 50 'engages with a member 51 (see Fig. carrictl by the shaft 5 or sleeve, (as the case be) according to which direction the slam. .,l, (or sleeve) was revolved from the normal: and causes the shaft (or sleeve) and drum 2, to he returned to their normal or inactive position. The tongs el), 50 will be recigrocated at each alternate operation of the punebingg; machine.

l provide a secondsct of slides for operating the locking plates 3Q, which can be operated independently of the first set and which are in fact operated alternately thereof. l

` On the shaft 7, is arranged the drum l.. which is in all respects similar to the drum 2. and it has pins extending outwardly therefrom, in the same orderor arrangement.

I have provided an oscillating' shaft 52, on which are carried the arms 53. and hetween these there is carried a har 5t. which is in all respects like the bar 24. It has apertures 56,'and pins 55 extending therethrough, with enlarged heads. Above each pin 55, l arrange' slides 57, 5S which coperate with the locking plates 32. The slides 57 are similar to the slides 30, but are preferably straight. The free ends of these slides pass through the apertures 59 in the guiding` plate 36, and are adapted to engage the plates, 232, below the slides 30, 31. These slides 57, 5S preferably nected with the plates 252, but are only adapted to move the latter, to the left lin- Fig. 1. The slides 57 have upward projections 5.) and CXO .which are adapted to be operated upon by the oscillating plate G1, carried upon a shaft G2, whereby the slides may be reciprocated in a similar manner to the previously mentioned slides 30. The slides 58 are arranged beside the slides 57 and alternate therewith, and they also4 pass through the guiding plate 36, and engage the alternate llocking` slides 32. rlfhese last slides are provided with projections G3 and 64, with which the oscillating,r plate G5, carried upon a shaft GG, engages; and by means of the oscillating plate the slides 38, are reciprocated at certain periods, to move the locking plates with which they engage'. rllhese slides 5S are preferably straight.

The slides 30 and 57 each operate the same locking plates 32, while the slides 58 and 31, both operate the same plates 32, but the slides 30, and 31 and the slides 57 and 58 are operated at dillerent times, as will b'e apparent hereinafter.

On the shaft 67 l have mountedl an arm (58, which carries the tongs G9 and 70, and these tongs straddle the shaft 7, and operate upon the engaging member 51 of the shaft, to return the latter and the pin drum 1, back to its normal position after each operation: but the tongs G9, 70 operate at a ditferent time to the tongs -l-9: that is, they are alternating in their movements. These tongs and their operation may' be fully understood hy referring to niylhitent (Sillo. dated ,April 11, 1h05. l have provided hars '7l and T2, as stops for the slides 2.., 31 and 57, 58. respectively.

When the pin drums Q, are operated. eer

tun of the slides 30 and 3l will be selected hy the pins l, on the several drums. according to the positions to which the drums are moved. while certain of the slides 5T, and 5s' will be selected, when the drums 1 are operated. :urording' to the positions of the latter. 'l`lie-'e drumsv l. and L, ara' therefore adapted to produce the same results in ro g 1rd to the loehing; of the prueh rms. lluy are adapted to he operate-i alternately Jever. :in-:l to bring` this about .l preferablf.Y connect the drums 1 and il, with the stitch determining. inechau-nn alternately.

On t; `haft l' have provided a pinion 1Q, while on the .shaft 7, l have provided for the purpose of locking the latter.

a similar pinion 13, which is adapted .to be' singly and alternately operated by the gear 9, on the shaft 8. It 1s tobe understood that there will be a gear 12, for each pair of pin drums 2, and a gear 13 for each pair of pm drums 1, mounted on the shafts, `or sleeves which carry the drums, aswill be understood. Also there' will be a gear,9, on the shaft 8, `for each pair ofppinions 12v and 13.

In the huh 73 of the gear 9, I provide a r groove 74, in which engages the pin 75 on the arm 76 ofa shifting lever. This lever fulcrulns on a shaft 77, and has an arm 78 which is connected with a link 79 by a pin 80 which has'play in the slot 81 in the flink. The rocking of the lever 76, 78 73 causes the gear 9 to be shifted longitudinally on the shaft 8, for the'purpose of throwing the gear 9 in to mesh with either the pinion 12, or the pinion 13, but not both; and the lever is operated to shiftthe :sleeve and gear after each setting of the stitch determining mechanism. Itv will be noted that the'pinions 12 and 13 are not'in line with each other, (see Fig. 7), and therefore the gear 9 will mesh with only one of th'e pinionsat any time. l p

The link 79 is fulcrumed to anarln 8.2, of a lever which journals on the shaft 83, and the power for operatingthe shifting mechanism is preferably transmitted to an arm -841. on the same hub as the arm 84.

I prefer to provide the mechanism ,for alternately lockingl the stitch determiningdrums where it will act upon the pinions 12 and 13,. On the shaft 83, I have arranged the arms 86 and 87 which extend toward the pinion 12 and on the ends of these I provide the dogs 88 and 89 respectively,

which are adapted to eng'age between the'r teeth of the pinion 12.

The logs 88 and 89 are arranged to travel in different arcs. andI preferably cause this by arranging the dogs `88, and 89 onv the arms 86 and 87 at different-radial distances from the shaft 83, where the arms fulcru'ln. Extending in the opposite direction from the first mentioned arms, I provide arms 90 and 91l which fulcrum from `the shaft 83,

-and which cariv dogs 92 and -93 respectively;

and these dogs arev caused to travellin different arcs preferably by arranging them at (litfcrentriradial distances from the shaft 83. The dogs 92 and 93areso arrangedl as to enter between the teeth of the pinion n the ears 94 of each of the arms 86, 87 I con nect spiral springs 95,- 96 which tend to draw the arms 86, 87, dogs toward their pinions.- This movement caused by the springs is a resistable one, while the movement of the armsawayfrom the pinions .is causedbypos'itive means. On

the shaft 823, l alsoprovide on the sleeve 85,

. A one arm 90 and 91 and their arm 68. At each v.singularly disposed arms 97 and .98 each of which has a Contact pin 99, 100, the former being arranged 'to engage the arms 86, 87, while the lattte'r is arranged to engage and move the arms 90,v 91: These armsl are adapted to rock 4with, the sleeve 85.

There are various cams,shafts andlevers vprovided for operating the several devices previously. `described at various predetermined perlods and t'ey consist of the following: The shaft 101 is the main shaft of the punching machine and corresponds with,

and is operated by, the same mechanism as' the lshaft H of mysaid Patent Number' 627,266, but-for convenience I haveo'mitted part of the device for operating this main- Preferably parallel with Athe main shaft I provide a secondary' shaft 102, which is ar ranged to be operated at half the speed of the main shaft, so that while the main shaft makes one complete revolution in one comv plete punching operation, lthis shaft 102, makes one half revolution, or one complete `Vrevolution for everytwo punching operations. .I have provided a gear 103 onthe mainshaft 101 and a gear 104 on the shaft 102, of twice the 4size of gear 103, so that the shaft 102 is operated from the main shaft at half' the speed of the latter. On a Ishaft 105, I have fulcrumed a lever 106,

which isconnected by a link 107, with the arm 84,wh ich y fore operates the shifting and drum locking devices. The lever 106 carries a' bowl 108 which travels in the canr groove 109, of .a cam 110' on the secondary shaft 102. The arm 84, therefore, will be rocked to the .left atone operation of the Apunching mechanism, and to the right at another, remaining in -its extreme positions substantially the whole time of the punching operation.

rocks the sleeve 85, and there- .The returning tongs 49 and 50 are 0perated 'as follows: On a shaft 111, I fulcrum a one arm lever 112, which carries a bowl .114, which travels in the cam groove `of a cam on the secondary shaft 102.

- To the v stud of the bowl is fulcrumed a curved link I 113. The link 113, is also fulcrumed to an' arm 117 which is mounted on `shaft 47, whichyalso carries the arm 118. At each revolution of the shaft 102, therefore, the

are caused to'- fall, and returnthe pin drum 2, and rise again to the normal position. lever 118, is fulcrumed on a shaft 119, and carries a bowl 121 which travels in the samecainv oove 115, as the-.bowl 114. To the stud of the bowl is fulcrinned a link 120. The link connects `with the arm 122, onshaft 67, which also carries the tongs 69, 70 will-be caused tofal'l, and there'- by return the pin drum 1, to its intermediate 'lever.48, 117 is rocked and the tongs49', 50j

revolution 'of the shaft A 102,'the lever 68, 122 will be rocked and the or normal position, and then rise again to its own normal position. As the/bowls 114 and 121 engage the cam groove 115,011' opposite sides thereof, the levers 48, 117, 63, 122, will be caused to rock alternately and one at each complete operation of thepunching mechanism. y

The arms 25 and 33, which carry the bars 24 land 54, in which the pins 28, 55, are mounted, areoperated as follows: I provide a lever 123, which fulcrums on the shaft 124, and on one end it has a bowl 125, which travels in'the cam groove 126, of a cam on the shaft 102. To thc other end of the lever 123, is fulcrumed a link 127 which extends over, and is fulcrumed to an Y arm 128 which is secured to the shaft 26,

whichcarries the arm 25. The movement of the lever arms 128, 25 both of which are carried on the shaft 26 causes the bar 24, to be oscillated once for every two punching operations. A lever 129 is fulcrumed on a shaft 130 and one end hasa bowl 131 which travels in the groove 126 of the same cam as the bowl 125, of lever 123. To one arm of this lever is fulcrumed a link 132 which is also fulcrumed to an arm 133, which is se Y cured to shaft 52, which shaft carries arms 53. The rocking` of the lever 13 3, and arm 53 on shaft 52, causes the bar 54, to be oscillated, once for every second punch-operai which is secured to and rocks the shaft 40,

thus oscillating the plate 39, at every second punching operation of the machine. A lever 140, fulcrumed 'on the shaft 141, also has a bowl 142 Ilwhich travels in the cam groove 137. A link 143, fu-lcrumed to one end of this lever is also fulcrumed to an arm 144 on theshaft 44, and the movement of the lever'140, causes the shaft 44, to oscillate, thereby moving the plate 43. As the bowl 142, is' slightly in the lead of bowl 136, the shaft 40 will be oscillated slightly in advence of shaft 4 4. The other push plates are similarly operated and preferably from the same cam.' A short lever 145 fulcrumed on the shaft 146, has a bowl 147 traveling in the cam groove 137. A link 148 is fulcrumed to lthe lever 145 and is also fulcrunied to an arm -149 on the shaft 62.. rlhe shaft 62 and its push plate 61 are therefore oscillated at 'every secondl punching operation of the 'machine A lever. 150 is fulcrumed on a shaft- 151 and it has a bowl 152 which travels in the cam groove 137. A link 153 connected to the lever 150 is also fulcrumed to an arm 154, on the shaft 66, whereby the latter and its push plate are oscillated at every second punching operation. As the bowl 147 trave-ls in advance of the bowl L52, in the cam groove 13T, the shaft 62, will be oscillated slightly in ad Vance ofthe shaft 66. As the bowls 142, 136 engage the cam groove 137 on opposite portionslto the? bowls 147, 152, the shafts 40, 44, and 62,' 66, will be operated in alten nate relation, one pair at one punching op eration and the other at the next, and so on. The push plate 45, has to beoperated twice for each complete-Lrevolution. of the main shaft or at every time the punch block has acted; and I therefore prefer to operate this from the main shaft. I have 'fulcrumed the lever 155, on a shaft 156, and one end carries a bowl 157which travels in a cam groove 158 of a cam on the main shaft 101. This cam has two rises and therefore the lever 155 will be twice rocked for each revo lution of the main shaft. A link 159 is fulcrumed to one end of lever 155 and the other end is `fulcrumed to an arm 159 on the shaft 46. The operations of the lever 155, will cause the shaft 46 and its push plate 45 to ,oscillate twice for each complete `punching opera-tion of the machine, as it is necessary in this 'form of machine to return `the locking slides twice.

'The control- The present mechanism` can be'initiated separately for each punching operation, or the initiating device can be locked in position whereby the machine will operate continuously, in which latter event the operator-will have to lay out stitches as fast as the machine runs. .That is, he must position one set of devices before the other completes its operations. On the main shaft 101, I have shown a cam 160, which is pref erably the same as the gear wheel with cam Groove z, of my said patent. The lever 161, 2fulcrumed at 162, is similar to the lever g2 of said patent, and the arm 163, on this ,lever preferably performs the same functions, by means of similar connected devices as the arm g, in said Ipatent.- That is, it controls the starting and stopping of the main shaft. On a shaft 164, I have fulcrumed a three armed lever which issomewhat similar to g, 912. (/1-3, in said patent which is employed to initatethe operations of the machine' by hand control. To the arm` 165, of this lever is connected a rope 166, which is similar to the starting rope g, of my said patent; andthe latter passes up to a convenient positionvwithin reach of thc' operator. This rope, at its u per end is connected to a lever at tne top o the machine .and the other arm of this lever is connected with a rod. 167 which latter is fulcrumcd to the arm 168, all of which "is described in x said patent. The arm 169, forms another member of thislever, and 1s rocked whencorresponding with ever the arms 165 and 168 are rocked by the .operator pulling the starting rope. The arm 4169 lies Linder al lateral pin '170 on the arm 163 of lever 163 and projects into the path of a pin 171 carried upon the cam 160 on the mam shaft. A trigger172, is fulcrumed on a stud 173, and the end 174, of thi s trigger also projects' into the path the pin 171.

The nose- 17 5 of this trigger is arranged. to engage the. abutment 176, of the arm 16%), y. to hold the latter in certain positions, and' the frame of the machine, nearthe opera-k'A tors Working position. Upon a stud 180, on the frame, I have fulcrumed a catch 181 which is adapted to be rocked by the operator, into and out of engagementwiththe bioci; les, @1i-the marier@ -hoid manner `ir i its elevated position, Whenever it 'is desired tooperatethe machine continuous-ly.'

The operation of my invention, when ein bodied in a machine of ghe character hereinv referred to, -WilL be as ollows: Assuming the machine embodies all the features shown in said letters patent, except wherein they are superceded by devices shown herein, and the parts to be in the normal or kinactive position, theoperations will bel as Jfollows: The operator will. 4move the -cross frames shown in said patent, to bring the pointer to the position on the pattern, corresponding with a stitch to be made byI4 the embroidering machine. The movement of the cross frames has moved, by mea-ns ot the mechanism described in said patent, the several shafts or sleeves (as the case may be on which the gears 9, are carried). This will rotate the gears 9 to an extent corresponding with the movement ot the cross frames and. the drums have been rotated to the position the severalv units' ot' movement to be combined in the jacquard and transmitted to the tambour frame of the embroidering machine. This operation positionsl the gears 9,`the same as the gears g2g-g were positioned in my said patent.V It' tion'of one chain of elements, as the others will be all similar. Let it be assumed that left, as the case may be,

gear 9 is in position to-mesh with pinion 12. determined and the the pinion 1Q, was likewise revolved in accordance therewith. Since the pinion 12connects. with one pair of drums 2, the latter Will have been' moved toI the right or lett, from their normal or 1nwill only be necessary to follow/,the opera-V the pins 4,on leach of the drums, underjits corresponding pin 28, of the slide selecting ftermediate position, thereby bringing one of i' dev-ice. The particular'pins 4, thus brought J under-alpin 8, will' depend upon the direction and Aextent of rotation, of the drums 2, the same as in the caseofthe drum e, e, e2, and es, of my saidpatent. During this positioning ofhthe drums 9., the drains 1, lie

`idle because the pinion 13 is not in mesh With the gear 9. The positioning having taken place`,*the operator pulls y*the rope 166, to set the'l*unchinglmechanism into operation, to ,ma ert-lieneeessary perforation rep resentingy such stitch. yThis rocksthe lever' 169, trips theleverl and,'tlirough the mechanism shown in'my said patent, en-

gages the frietionwlutch g1, vvith the driving pulley g of lsaid patent, and the main @shaft-.then beginsto revolve, to the right in Fig.A The'mov'ement of the main shaft will be" transmitted through gears 103 and 104, 'and the'sha'tt e102 will be revolved at half the speed'f -th'e mainshaft. The first. action will betorocklever 106, push the bar 107 to thev right, by which action the Apinion 12, will bepositioned, pinion 13, will aol e released and gear Q willbe shifted to dis `engage from pinionlilll, andffengage with pinion '13. l As soon as' thisfmovement `is completed 4the operator can againv move the,

cross frame and thereby position' `the -pinion 13 and the drums connected thereto. `.In the meantime the rotation of the main shaftV continues and the cam groove 126 will cause loa the lever 123 to rock, and consequently the j shaft Q6, will be oseillatedto move the bar 24, which carries the 'pins 28, to\vard`and from the pin drum 2.- VVhen'the bar .24, goes down, the pins `28, which are .not op. plosed by a pin 4, on the pin drum 2,-will go own with the bar; while the one 'which strikes a pin 4, -on` the-drum Q, will be held' up. The ones so held up will retain the eor- .responding slides 30, 31, in raised position until t-he push plates act thereon. The cam groove 137 Willnow cause'tlie lever ltlrl-to whereby the shaft 4() will be oscillated,

rock, and with it the push plate 3D. The slides 2l@ which are in the raised position, held there by the pins 28, will be caused to nioi'e to the left in Fig. l, by thev push'plate and they willV move their Correspondiiig locking plates Si., forward, until they come in such a position'asto lock certain of the lirst row of punches 18.' The punch bar 23, will non' be lowered by the mechanism shown' in my said patent` and the punches which are locked by the slides will perforato thc paper pattern; will have no action on the paper, simply rest v'upon the surtacew punch bar .23, returns and the punching rods have been withdrawn from the card. the push plate 39, will return the slides BO.

but will 'A ttor the which were advanced, to their former posi! tion g' and the push plate 45, will return the locking plates S2, to their former, or inactive posit-ion. The paper card Will novv be advanced by the mechanism shown' in said patent, the distance between the tivo rows of punches 18 and 19, to bring the perforations just made, in line With the advanced punches 19. The slides 31, Which are held up by pins 2S, comprising part of the first set of slides, will now be advanced by the pushplate43, in consequence of the rocking of the lever 140: T he advancing of the slides 31, Will move their corresponding vlocltinor plates 32, forward to lock their punch rods 19. The punch bar 23, is now again depressed and punch rods of the forward row 19, which.

have been locked, vrill perforate the paper card; and these perforations will come 1n. the same transverse line as the first perforations made by rods 18. After the punch bar is raised, the push plate 43, will return the slides 31, which were previously advanced, to their former position and the push plate 45, will again rock, to return the plates 32, which were last act-ive. The machine vhas now completed one punching 'operation the main shaft 101, hasmade one ,complete revo lution and the .shaft 102, has made Vone half a revolution. I

lVhen the arm 165 was tripped by the pulling of the rope the trigger nose 17 5 engaged under the projection 17 6 on the arm 169, and the trigger continued to hold up. the arm 169. Shortly after the shaft commenced its'revolution the pin 171 on the cam .vill trip the trigger arm 175 to release the trigger from engagement with the arm 169, and it Will also engage the. arm 169 and return it to its first or lovver position, so that the lever 163, and 163g, and itsstopping mechanism will disconnect the clutch mechanism, so that the main shaft `Will be stopped after its complete revolution. Should however the operator have repositioned the cross frames-and pulled the rope` again before the shaft has completed its revolution, then the trigger will hold the leverl 169 during the period 'when the clutch mechanism would be disengaged and' such disengagement cannot take place, but thev machine will continue to run another stitch or until the operator fails to be on time in pulling the rope. After the gear 12, and the drum 2, had'been positioned preparatory to the last operation, thegear or pinion 12, and the drums connected thereto, were being I locked by the dogs 88, S9 as shown in Fig. 5,

by the earn' groove 109,' causing the lever 106 andby means of the bar .107, thearm 84 to rock to the position shown in Fig 4. This rocked the sleeve 85, and with it the arms 97, 98. 'The rocking of the arms 97 `and 98 and their pins 99 and 100 permitted the "springs 96, to rock the arms 86, and 87,`

.toward the' gear 12, and the dogs 88, 89, thereof, enter the teeth of the gear 12, and lock it against any movement; and this gear remained locked until the punching opera` tion just described Was completed. The rocking of the arms 97 9S, also caused the arms 90, 91 to be rocked andtheir dogs 92, and 93, were moved out of the teeth of the gear 13. vWhen the sleeve '85, was rocked, the arm 82, also rocked, causing the link 79, to rook t-he lever 78, 7 6. Thisin turn acted on the hub 73, of the gear 9, and the latter Was'moved out` of mesh with the gear 12, and into mesh with the gear 13. This shifting of the gear 9, is delayed long enough to allow the dogs 8,8, S9 to be released from the gear 12, and the dogs 92, 93, to be engaged with the gear 13, ,in order that no change will take place in theposition of the gear 13,

sol

That left the gear 13, and its pin drum free to be positioned by the operator as soon as the iirst punching operation was initiated. The operator, as soon as he pulled the rope 166, as previously described, may proceed to lay out the` next stitch While the punching operation is going on. To do this he operates the cross frames, in the upper part of the machine, above referred to, and lays out the next stitch.' As the gear 9, is nonr disconnected from the pinion 12, this can be done; and the operator, if quick, can perform this 'operation by the time the first punching operation is completed. As soon` as he succeeds'in so positioning the gear 13 and its drums 'he again pulls the r0pe`166, and if the first operation has' been completed, the following` will result: The positioning ofthe gear 13 and its drums brought certain of their pins 3, under certa-in of the pins 55, according to the directions and eX- tent of rotations of the drums, the same as was the case in the action ofthe drums 2. Through the cam groove 126, the lever 129 and link 132 and arm 133 on the shaft 52,

and the arms 53, thereon, will be oscillated,

link 148, and arm 149. In moving forward,

the slides 57 will carry their respective locking plates 32, forward, and into locking engagement with their respective punch'bars of the front row 19. The punch bar 23, is now'lowered, and raised-as before, andthe punch rods which are locked will perforate the card. .The ret-urn movement of the push plate 61, will return the slides 57, which were advanced, back to their starting position, -and the push plate 45, will return the locking plates 32, back to their inactive position. The jacquard card will now bd fed by the mechanism shown in my said patent forthat purpose equal tothe distance between the tworows of punches 18, 19, to bring the perforations just. made, in 'line with the forward row of punches 19. The push plate (35, is now oscillated, by reason of the cam groove 137, lever 150, link 153, and arm 154 and it will move the slides 58, lwhich have the projections 63, 64 and which are held up by the pins 55, forward. They will carry with them their respective locking plates 34, which will be moved into locking engagement with their respective punch rods 19, in the rear row. The punch bar 23, will now 'go down again to force the locked punch rods through the card, and will then be raised. The push plate 05, will now return the slides 58, which. were advanced, back to their starting position. The push plate 45, will also return -the lates 34, back to their inactive position. Before the punching operation, just described, has been com-y pleted, and in fact, immediately after it has been initiated, the lever 106 is again rocked, and the link 107 lever 84, 82, link 79 and lever 7S, 76 will cause the gear 9, to be shifted from its engagement with gear 13, to engagement with gear 12.

lVhen the second punching operation has been completed the main shaft will have made'its second revolution, and the shaft. 102 will have made one complete revolution and the parts will be brought to a stop, as before. Y

After the first punching operation was over, and the slides 30 and 31 were returned,

and the bar 24, raised to its upper position, the pin drum 2, was returned to its normal or intermediate' position. This was caused by the cam groove 115, link 113,' and anni 117, moving the shaft 47, so that the tongs 49, 50, which are lnormally in their high position are lowered and yin their dowi'nvard .movement elther one or the other meets the projection 51, on the shaft 5, and ret-urns the latter and associated parts back to their intermediate position ready for a subsequent operation; and then the tongs are raised again tothe high position. Also, after the. second punching operation,the cam groove 115, lever 118,",link120,"vr arm 122, shaft 67,'

and arm 88, caused the tongs 69', 70, to fall, and to return the drums insimilar manner tothe first tong's and then rise again. These` the main shaft run continuously, if the operator canlay o-ut a new stitch each time,

before the last punching operation is completed. To do this, the trigger 181 is thrown over tothe dotted line position shown in Fig. 2, where it will engage the block 182,

and retain the rod 17 8in its raised posit-ion.

This( will keep the arm- 163L raised and the.

stop mechanism will no-t operate, so that the main shaft will remain connected with the source of power, and will operate continuously. In that `event, the operator will pay no attention to the starting 'or initiating device, but will simply lay out `new stitches as fast as, and slightly in lead of,I the pnnching operations. Avoiding the stopping of the machine after each operation, saves time, and wear' and tear on the machine/ Itrmay be stated again that between the two punching actions of each complete punching operation the card is advanced one position by the feeding mechanism sho'wn in my said patent.

As has been said, the dogs S8', and 89, and likewiseA the dogsI 92, 93, are arranged to enter the spaces in the pinions at different angles relative to the radii, and I prefer to -cause this by arranging them at different radial distances from a common center, rather than to strike their arcs from different centers. ehines it has been found that after the gears were rotated they might he in such a position that the locking dogs would engage the top of a toot-h thereof, 'and the locking would not properly take place, as the dog would not enter bet-Ween the teeth. In the present arrangement 'the dogs 88, 89, in approaching the teeth of gear 12. and likewise the dogs 92, 93, in approaching the teeth of gear 13, do so at different angles relative to the radii of the gear and one after the other. If the first one should enter properly in the gear it will be drawn down to t-he full extent between the teeth and the gear is properly deg-the'first'one will then also escape the' top ofthe tooth'and enter its proper space. From the above it will be apparent that In previous punching ma-- -locked and the second dog would follow. 1

a jacquard card may be produced which will he similar in all respects to cards produced on lprevious machines.

Instead of laying out a .stitch andy then initiating the punching'loperation and havingto wait until the latter is completed and theparts restored, before proceeding to lay 'p out a second stitch, the delay is avoided and the operator can lay out stitches` as fast ashis ability will permit and he need not Wait for any appreciable length of time.

vdust as soon as a stitch has been laid out by positioning the firstset of pin drums, and the machine is initiated, he immediately proceeds to lay out a second stitch by ositioning a second set of drums, which in the meantime been connected up With the cont-rolling mechanism. This second positioning of the second set of drums selects from a secondi set of slides, which .are ready to advance just as soon as the first set of slides have been returned, and so on. It is therefore apparent that in permitting the operator to lay out a new'stitch "as soon as a punching operation has been initiated. under my present invent-ion, the punching operations of my machine are not made slower, but in fact are made faster, because of the double arrangement of slides, both of which perform the same function, in rapid succession. When one set of slides performs its function and is returned, the second set is alreadyselected and ,is ready to perform its vfunction at once.

It Will also be apparent that the machine is positive in its operation and that there can be no conflict in its several devices.

Many changes may be made in-the numbersof parts their arrangement and construction Without depart-ing from the scope of my invention asset forth in the annexed claims. Furthermore, my present invention is not limited in use tothe particular form of punching machine herein described; and parts of my invention may be segregated and used for their individual advantages.
