Application filed February 5, 1910. Serial No. 542,305. i

To all whom it may concern:

Be it known that I, ROBERT ZAIIN, a resident of Pla-uen, in Saxony, in the En'ipire of Germany, factory manager, have invented certain new and useful Improvements in Embroiderydllacllines, of. which the follow ing is a specification.

This invention relates to embroidery machines of the autoi'natic type and has for its object to provide such machines with means for displacing the emln'oidery :frame under the control of a perforated record strip or pattern card commonly known as the jacquard card.

The invention moreover comprises devices in cooperation with one another and combined in the manner hereinafter fully explained and shown by way of example in the accompanying drawings in which- Figure l is a lateral elevation illust 'ating more or less diagramniatically an automatic embroidery machine according to this invention. Fig. 9 is a plan view of'certain parts of Fig. 1. Fig. 3 shows again parts of Fig. 1, representing one form of a mechanism according tothc present invention. Fig. 4 a lateral View of a mechanism according to another form of this invention. Fig. 5 is a lateral view of a third constructional form. Fig. 6 is a lateral View of a fourth example of which Fig. 7 is a plan view. Fig. 8 illustrates on an enlarged scale, parts shown in the right-hand portion of Fig. 1. Fig. 9 is an elevation of the same parts viewed from the right-hand side. Fig.

10 represents a detail of Fig. 1. Fig. 11 is a plan View thereof. Fig. 12 represents a repetition of the parts shown in Fig. 10, but in a different working position, and Figs. 13 to 15 areperspective views of a detail of Fig. 1 indifferent working positions.

,The numerous mechanisms of the complete arrangement will hereinafter be considered in groups which are located at about the places indicated in Fig. 1 by the letters A, B, C, D, E, F. These mechanisms so intimately interengage with one another as to render their distinct separation practically impossible. The grouping above indicated has therefore only the object to facilitate the understanding of the specification. The various groups embrace the following mechanisms: i a

A. The jacquard apparatus.

B. The mechanisms for determining the throws or lengths of the displacements of the en'iln'oidery frame.

C. The mechanism for adding up or totaling the large and the small movements.

1). The i'orwihanisms fordctcrmining the direction of movements.

I The safety device.

F. The driving mechanism.

The jacquard apparatus-A paper. strip 1. fed betweent-he rollers 2, 3, and is advancedv intermittently in the direction :r, y, and after each advance is moved against a row of jacquard needles l'in the direction of the arrow 2, see also Figs. 10, 11'. and 12. Each jacquard needle 4 is socured to a prismatic bar 5. These bars 5, are join-railed in the machine frame so as to be movable in their own longitudinal direction. Engaging with each bar 5, is the hook-shaped end of a wire 0, the other end if oneof'the bars 5 is moved in the direction of the arrow 2, the bar 7 connected with it by the wire (3 is forced to perform the same lllOYclTlQlit as will he clearly understood from Fig. 13. Arranged between the horizontal bars 7 are vertically movable bars 8 diagrammatically indicatcd in Fig. 1 by thick lines and shown in perspective View in Fi l3. Secured to each bar 8 and projecting laterally therefrom are two pins 9, (Fig. 13) between each two of which a bar 7 is guided It therefore one of the bars 7 is raised or lowered, the corresponding vertical bar 8 is forced by the pins 9 to rise or to descend accordingly. The rear end of each bar 7 is provided at-its lower edge wit-h a re- 10 and on its upper edge with a recess 11. Capable of entering the recess 10 is the upper edge of a cross bar 12, and adapted to engage with the upper recess 11 is the lower edge of a transverse bar '13. If, owing to the movement of the record strip or pattern card the whole of the jacquard needles 4. are pressed back as will be understood from an inspection of Fig. 1-, the recesses 10 and 11 of all adjacent bars 7, are *aused to coincide in a continuous line respectively; These recesses thus. form two troughs l0 and 11 which are so located with regard to the transverse bars 12 and 13 as to enable the bar 12 to enter the recesses .10 when moved in upward direct-ion as 1ndicated in Fig. 14. If, in this case, the bar 13 is moved downwardly it does not enter of which'is rigidly secured on a. bar 7. Thus the recesses 11 but comes to rest upon the upper edge of the bars '7, thereby depressing back, whose needles 4: encounter the solid pap'er surface. This operation is exactly the same as that known in acquard devices of a loom. Some of the needles and their corre-- -'spond1ng bars 5, 6, 7, however, are not forced back during this movement of the roller :2, but retain their position In this case the recesses 11 are opposite the bar 13 as indicated in Fig. 15, whereas the recesses 1.10 are not in the path ofthe bar 12. Thus if the bet-r12 is raisedit raises the bars 7 and consequently also the corresponding bar 8.

A driving mechanism which is immaterial to the invention and therefore is not shown in the drawing causes the rocking of a lever 15' shown in Fig. 1 in order to enable its hook-shaped end 16 to'engage with recesses 16 in the'ba-rs S and to thereby safely hold these bars for a moment in'that elevated position to which they have been raised by the. 7 bars 7. As a rule there are eighteen acquard needles or pins hand accordingly eighteen bars 5, eighteen wire hooks 6. and eighteen bars 7. whereas only nine bars 8 are arranged to 'extend in downward direction.

[The other nine bars are marked 17 and extend in upward direction (see Figs. 1 and 13). These upwardly directed bars are likewise raised or lowered by the transverse bars1'2 and 13'. The movements of the nine bars 17' are transmitted by bell crank levers viz; vertical direction.

pivoted on a stationarypivot 1 8,- to bars-19.

Those parts of the jacquard mechanism which have so far been explained. namely,

the eighteen jacquard needles 4 and the .bars 8, 11', and 19 serve for automatically moving the embroidery frame of an em: bro1dery"mach1ne only in one dlrectlon namely horizontally. An equal number of parts is provided to effect the movements of'the embroidery frame also in the other This is apparent from the provision of the double sets of wheels D- D shown in Figs. I and Qand v hereinafter explained. The set of wheels D" equipped with a toothed rack r serves for transmitting the horizontal movements and the wheels D provided with a 'rack g are arranged for the transmission of the vertical motion. The two racks 0c and 3 are connected by transmitting meansto the embroidervframe. The two wheel sets Dand -D are of entirely similar construction but as regards their arrangeiuentin the machine left andto the right. 'hioreover thej are set at right angles to each other so that the representation of the set D in Fig. 1 may in a way be looked upon as being a plan view of the representation of D in the same figure while in Fig. :2 the illustration of D in that figure.

From the foregoing description it. will be understood that in the complete mechanism of a machine as shown in Fig. 1' the parts 4, 5 6, 7, etc., .will .be contained thirty six times. Of this total eighteen parts are alof D may be said to represent a plan view lotted to the wheel set Dv and the other I eighteen to the wheel set D and of each of these eighteen parts nine belong to the bars 8 and the other nine to the parts 17. 18,19. For the sake of completeness and as will hereinafter be explained, it should here be nientioned. that besides the thirty-six jacquard needles- 1 which only determine the -moven'1ents of the embroidery frame in vertical or horizontal direction, there are in the same row other Jacquard needles for the purpose of so controlling the two sets of wheels D" D that each vertical movement is 'caused to take place "at one time upwardly and at another time downwardly. while the horizontal movements are accordingly controlled to take place alternately each to the one jacquard needle 4: is arrangedwith the objectof protecting the whole mechanism against in ury,'sav in case the machine is started accidentally or by unauthorized persons in the absence of a acquard strip 1; j

ewzems of-moz'menfs for the displacement of the embroidery frame. The bars 8 1npractice are arranged as shownin Fig. 1 in one row side by side. so that the foremost bar obstructs from view all those arranged behind it. In Fig. some ofthese bars are .sliown diagrammatically in order to indicate that each bar 8 is provided with a horizontal arm 20. Gliding on each horizontal arm 20 is the right hand end of a coupling rod 21. The left hand vend of each couplingv rod is rotatably secured on a pin The right hand end of each coupling rod. 1S 'ClfiW shaped so as to enable its being coupled with a pin 23. .For the sake of simplicity these pins 23 are in Fig. 3 indicated by -cir cles. In reality, however; they are of rectangular shape. as shown in Fig. 1. The .pins 22 are secured to a lever 2i Journaled m the machine frame so as to rock about pivots 25 (see also F1g. 2) "and operated by a powerful driving mechanism so as to oscil late to the extent-indicated bv the arrow'i i in Fig. 3. As will be seen from Fig. .2 two Attached to such levers 2% are arranged.

ice B. The. mechanism for data 17715212 39 the.-

each lever are, nine coupling rods 21.- Of

these latter. four are shown located at one. side (Fig. 1) andtiv'e'iat the'other side of. the lever 94 (Fig.;3'),fowing to diagram matic representations having been resorted to. Otherwise all nine coupling rods 21 would have to appear in Fig. 1, but this deviation from the reality has been resorted to for the sake of clearness'. During the oscillation (26) of the lever 24 the coupling rods 21 are given different throws. The uppermost coupling rod 21 receives the largest throw owing to its fulcrum 22 being remotest from the pivot 25 of the'lever. There are as many pms 23 as there are coupling rods 21, and of these pins again four are shown on one side (Fig. l) and five on the other side (Fig. 3) of a slide 27, 28, 29, 30 both ends of which are of prismatic shape and which is movably journaled in the machine frame. Upon the raising of one of the bars 8. its arm 20 raises the corresponding coupling rod 21 so .asto couple it with the corresponding pin 23. The slide 27 is thereby forced toperform a movement the length of which is determined by the distance of the corresponding pin 22 from the fulcrum 25. A mechanism similar'to that controlled by the vertical bars Sis provided for the horizontal bars '19.' The reference numbers 20', 21 22', 23', 24., 25', 26, 27', and 28' have for the second apparatus exactly the same meaning as havethe numbers 20, 2.1, 22, 23, 24, 25, 26, 27, 28, described in connection with the first apparatus. There is only one difference between these two devices viz: The horizontal slide 27 28, 29 carries at its right hand end a link or bolt 30 whereas the vertically guided slide 27', 28, has its lower 'end provided with a horizontal. prismatic notch 31 guided in which is a 'prismatic sliding head 32.

C. The mechanism for adding up the large and the small m0vements.- he slides 27, 27 thus serve to allot the movements varying in extent in accordance with the coupling effected by the jacquard mechanism, from the graduated levers to the other organs and are, therefore designated in the claims as allotting members. Yieldlngly attached to the sliding member 32 of the slide 27 28, 31 is a bell crank lever of which one arm 33 is very long and the other 34 very short. The ratio of length of these two arms is 10:1. The fulcrum of this bell crank lever 33, 34 is constituted by a pin 35 which is secured to a horizon-tally movable slide 36. The pivot 30 on the slide'tail 29 is connected with the lever arm 34 by a link 37. One side of the slide 36 is provided with a rack 38 by which the wheels D are caused to rotate.

The operation ofthe mechanism 30. 31, 35 is as follows: Assuming by way of example, that the slide 27, 28, 29 1s caused to perform a horizontal movement while the slide 27, 28, 31 is stationary. The sliding fm ember'32. is thus caused to reciprocate 1n the slot31. and the slide 36 1s made to travel exactly the same distance as the slide 27,

28, 29. Supposing now the slide 27, 28, 29 to be stationary and the slide 27, 28', 31 to be caused to make a vertical movement, it will be seen, that this movement is transmitted to the slide' 36 by the lever 33, 34 attheratio of 10 to 1.

slide 27. 28, 29 to travel horizontally a distance of say 5 mmpand simultaneously the slide 27 28, 31 to perform a vertical movement of say 3 mm., thesev two.movements are both transmitted to the slide 36 which is thus moved to the extent of 5.3 mm., owing to the throw of 5 mm. being directly transmitted to the slide 36, whereas the throw of 3mm, owing to the proportion of the lever arms 33, 34, is reduced to the tenth part of the movement performed by the slide 27, 28', 31-. In this manner the throw of the slide 36 may be varied at will according to the operation of the bars 8 and 19 under the action of the jacquard apparatus. Its

shortest displacement viz: 0.1 mm. slide 36 receives in the event of the slide 27 being stationary and the slide 27 being drawn down by that coupling rod 21 which in Fig. 3 is farthest to the left that is to say which is nearest the pivot 25. A throw of 0.9 mm. is. transmitted to the slide 36 upon the slide 27 being again stationary while the slide 27' is drawn down by that coupling rod 21' which in Fig. 3 is farthest to the right that a is to say reniotest from the fulcrum 25. The throw of the slide 36 becomes one complete mm. when slide 27 is stationary and slide 27 is" moved to the right by that coupling rod 20 which in Fig. 3 occupies the lowermost position. The largest possible throw of the slide 36- is 9.9 mm. and it: is attained when both slides 27 and 27 are moved by those coupling rods 21 and 21 respective] which are remotest from the correspon ing fulcrums 25 and 25. The above numbers are of course uiere examples and the question as to whether the shortest throw should be 0.1 mm. and the longest 9.9 mm. depends entirely on circumstances and on the minimum throw chosen under particular conditions. for the minimum throw 0.25 mm. is chosen, the corresponding maximum throw would be I 24.75 mm.

The constructional forms shown in Figs. 4 to 7 illustrate how the adding up of large and small movements may be effected by means of mechanism other than the one above described. In these figures the parts to which functions are allotted similar to those performed by certain parts described with reference to Fig. 3 are marked with similar reference letters. The trapezoidal plate 40 in Fig. 41 is provided with two slots 41, 42 acutely inclined to one anotherand adapted to receive the prismatic sliding blocks 43, 4.4. The block 43 is connected with "slide 29 and block 44 is'attached to 55 purposeof operating the rack 38.

slide 36. The upper edge of the plate carries a prismatic bar .15 which is capable of sliding in a groove 31 of the slide 27 upon the two slides 29, 36 being reciprocated in horizontal direction. On the slide 27' being lowered or raised, the two slides 29, 36 are caused to approach or to move apart from one anotherrespectively. ,In'Fig. 5

the adding mechanism is provided with two The toothedwheel 52 is rigidly connected with the, differential wheel 5- and the latter is connected bymeans of a -pla-n'et gear 55,

-56 with a seconddifi'erential wheel 57. the

, shaft 58 ofwhich carries a smalljpinion 59 which engageswith'the rack 38;on theslide 36.-.;S imilarly the other slide 27 has yield- [so ble of being alternately. coupled with a p1n-,

inglyattached to its two rac'ksfitl, '61 capaion 63 which forms part of the differential gear casing 641-.

The operation of this-mechanism is as follows: If the slide 27 is held stationary and the slide 29 is. moved-with one of its racks 50, 51 in engagement with the pinion the latter-rotates the [pinion 54 which in turn rotates theplanet gear 55, 56. This planet gear transmits its movement to the differential .wheel57 Whose shaft 58 in rotating the pinion 59 displaces the rack 38. During this operation the casing 6i remains stationary. If, however, the slide 29 is held stationary and the slide 27 is moved its rack 60 or 61 causes the casing 64' to rotate in which case the planet gear 55, 56r0l1s on the pinion 54;

' which now should be imagined to be stationary, thereby rotating the toothed wheel 57. The two connecting rods 53 and 6:2 by which the racks 50, 51 and 60, 61 are alternately thrown in or out of action respectivelyare controlled by the jacquard mechanlsm and thereby determine the rotation which the pinion 59 is to receive for the I). The /nechdm'sm f0? defcrmming the direction of the '772-0'L772872ZS.-It will have been seen from the foregoing description that the slide 36 i 3. 8 and 9) secured to which is the rack 38 (is 1 3. 8) is so governed byythejacquard mechanism. to receive a throw of varying length. But with regard to direction. all of these movements of the slide 36, are alike that is the slide 36 advances always in one and the same direction and then returns to its ini tial position. Xo'w the mechanism shown in. Figs. 8 and 9 has for its object to so transmit the movements of the slide 36 to the rack gas to cause the latter to move either inone direction or in a direction opposite thereto. The rack 38 engages with a large whsel 65 which inturn meshes with a small pinion 66. Both wheels 65 and 66 are loosely rotatable on shafts 6T, 68. The 'pinion 66 and a pinion 69 are rigidlyconnected 7 together by a common hub so as to be r0- tatable on the shaft 68. The pinions 70 and '71, however, are fast on the shaft 68 and the pinion T2 is fast on the shaft 67. The pinions 69 and T0 are or equal size and so are the wheels 66 and 7 1, and the pinions 65 and 72'. An iron frame 73 movably journaled at 74:, T5 is provided with three cylindrical pinions 76, 7'7, 78. The pinion 76 is of a breadth enabling it to engage simultaneously withthe pinions 69 and 70. The

their inner ends while their outer ends are in mesh with 70 and 69 respectively. With pinions 77,- 78 engage with one another at the frame in its intermediate position as shown-in Fig. 8 all three cylindrical pin ions 76, 77,78 are out of gear with the wheels 69, 70. Upon moving the frame 73' to the right (in Fig. 8) the pinion 76 c0upics the wheels'69, 70 whereby the latter to tatein the same direction. If the frame 73" is moved to the left, the pinion 77 engages with wheel 70. and the pinion 78 with wheel 69 so that both the'wheels 69, TO and'wheels 65, '72 are caused to rotate in opposite directions. By means of the small pinion 7 9 these rotary movements are transmitted to the rack y whichoperates the embroidery frame.

The jacquard device A (Fig. 1) by means of the parts 4s, 6, 7,12, 18 and 19 already de scribed, influences a pullrod 80. (Figs. 1 and 8) which governs bellcrank levers piv oted at 83 on the frame'73 (Figs. 8 and 9) and provided with clawsSl, 82. These claws are capable of engaging respectivelywith laterally extending pins Sl, 85 on a three armed rocker 86. If the claw S1 isca'used to engage pin 81 the frame 73 movesainone direction. If however, as shown in Fig. 8,

claw 82 is caused to. embrace pin 85, the I frame 73 is moved in'the opposite direction. In this manner the: jacquard device causes by means of theparts 80, 83, 86 the cylindrical pinions 76%or 77, 78 to be thrown into action alternately, thereby determining. the

direction of ;n10vement' of the embroidery frame. I s

E. The safety; mechansm -The lever mechanism shown in Figs. 10, 11 and. 12

serves a double purpose. It has been vdevised .to safeguard in the first place each" grouping 0t the -jacquard needles ata deter-J mined moment, and as soon as the grouping has xerted its effect upon the mechanism B, to guse all jacquard needles to be advanced to heir initial position. In the second place that device serves for retracting all jacquard needles and thereby to obviate damage in the event the machine is started, for instance, 111 the absence of a jacquard strip 1 on the roller 2 in which case the whole machine needle bar 5 is provided onits underside with triangular notches, one 87 in front,

and one 88 in the rear thereof. The distance between these notches is equal to the throw of the bars 5. Apart from the notches above mentioned, the bars 5 are each provided on their underside with a rectangular recess 89. The safety bar 5 has in contra-distinction to the other needles, only one triangular notch 87. In the place of the rear notch 88, a plate 90 is secured to the bar 5. Rotatably journaled in the machine frame beneath the safety bar 5 are two shafts 91, 92. Each end of the shaft 91 has rigidly secured to it a lever 93, and these two levers are rigidly connected together by a prismatic rail 94:. By raising these levers 93, the bar 9 1 enters one of the recesses 87 or 88. The other arm of the lever 93 carries a pin 95 rotatably mounted on which is a bell crank lever 90, 97. A powerful spring 98 causes this lever to bear aganist a pin 99 as shown particularly in Fig. 10. Each end of the shaft 92 has rigidly secured to it a lever 100 and these two levers are securely connected to one an other by a cross bar 101 capable of engaging with the recesses 89'in the bars 5. Thus during the rotation of the shaft 92 the whole of the needle bars 5 are broughtinto a straight line by the bar 101 drawing back any bars 5 which may at that time be non-coincident with the others. The recess 89 in the needle bar 5', however, is wider in the rear than the others. Consequently the frontmost needle 4' is not drawn away from the roller 2 by the bar 101. Moreover,

rigidly attached to the front end of the shaft 92 is a lever 102 connected by a link 103 to the bell crank lever 97,96. Attached to the free end of lever arm 96 is a pitman 104.

which is operated by the main driving of the machine.

During the regular working of the magear chine, that is to say with a pattern strip 1 on the roller 2, the safety needle 4" by each movement of the roller 2 in the direction 2 1s forced away therefrom in backward direct1on,ow1ng to there being no perforations 1n the strip to cooperate with this needle.

During this operation therefore the bar 94: is caused to engage in a regular manner with the recess 87 in the safety needle bar 5'. ()n thebar 94 descending, the bar 101 moves all needle bars 5 forward again into initial position, as shown in Fig. 10. In the event, however, of there being no jacquard strip 1' in the machine and the latter is started un,-- intentionally or through an oversight, the lever mechanism described is caused to operate in the manner illustrated in Fi 12 of the drawings. With nopattern strip in the machine the safety bar 5 maintains its forward position and on the connecting rod 104 being raised, in starting by the driving gear, the bar 94: is prevented from entering the triangular notches 87, 88, and is stopped by striking against the plate on the safety needle bar 5. The connecting rod 104-, how: ever, continues its movement, thereby causing the lever 90, 97 to be disengaged from the abutment 99 against the action of,the

spring 98. The lever arm 97 now rocks the I shaft 92 together with the bell crank levers 100, 102 carried thereby, by means of the link 103 and thus causes the bar 101 to be moved to the right, with the result, that with the exception of the safety bar 5', all other needle bars 5 are moved away from the roller 2so as to be rendered inoperative. F. The (hiring mechanism.-The main shaft 105 of the machine (Figs. 1, 2 and 3) carries a number of eccentrics of which three, 106, 107 and 108, are shown. In contact with the circumference of the eccentric 106 is a roller 109 rigidly secured to a crank arm on a shaft 110 which, moreover, carries two levers operating by means of connecting rods 111, 112, the slide operating levers 24, 24; respectively. Engaging with the circumference of eccentric 107 is a roller 113 by which a rod 114 is vertically reciprocated (Figs. 1 and 8) so as to operate the levers 86. In engagement with the circumference of the third eccentric 108 is a roller horizontal and. Vertical rockin members,
