JACQUARD MECHANISM FOR EMBRO IDERING-MACHINES.

Specification of Letters Patent.

Patented Nov. 24, 1914:.

Application filed December as, 1908. Serial 170.468,!367.

To all whom it may concern:

Be it known that I, Ronnnr ZAI-IN, subject of the German Emperor, residing at Plauen, in the Kingdom of Saxony and Empire of Germany, have invented certain new and useful lmprovements in Jacquard Mecha nism for Embroidering-Machines,of which the following is a specification.

y The main object of the invention is to provide an apparatus permitting a much finer or minute control of the movements of the embroidery .t'rame than is afforded by any of the apparatus hitherto known.

The apparatus constructed accordingto the present invention comprises a rocking lever mounted on a fixed axis, and an adjustable lever one end of which is connected by motion transmitting means with the embroidery frame, and the other end of which can be moved upon and fixed to the rocking lever at any desired distance from the center of rotation 01 the said rocking lever.

Apparatus embodying the improvements of the present invention, is illustrated by way of example in the accompanying drawings in which z- Figure 1 is a side elevation of the lefthand side of the machine; Fig. 2 is a plan thereof. Figs. 3 to 9 are drawn to a larger scale than Figs. 1 and 2. Fig. 3 is a crosssection approximately on the line A of Fig. 2, Fig. 41 is a side elevation looking inthe direction of the arrow B and Fig. 5 shows the same parts looking in the direction of the arrow C. Fig. 5 is a detail view of a portion of the construction shown in Fig. 5, on a larger scale. Fig. 6 is a plan and Fig. 7 is a section on the line 6. Fig. 8 is a section on the line 2 looking in the direction of the arrow F. Fig. 9 is a section on the line G of F ig. S, and Fig.10, which is drawn to a much smaller scale than Figs. 1 and 2, is a diagrammatic view of the general arrangementot' the machine, shown in Figs. 1 to 9 coupled to an embroidering machine in such a manner that the desiredmovements are transmitted to the embroidering frame of the latter machine. Fig. 11 is a sectional clevation of a portion of the mechanism con trolled by the jacquard card. Fig. 12 is a view of the mechanism shown in Fig. 11 in another position.

punched in its edge for the purpose of rcgu lating the exact step by step advance of the card, by the engagement of pegs 7, pro

vidcd on the rolls 3 and 41. The rolls 2, 3, 4i, 5, are rotated progressively step by step by means of wheel gearing not shown inthe drawings. i

On each of the two vertical shafts 8,. 9, is rotatably mounted a feeler lever 10. As

shown in Fig. 1, the shaft 8 (as also the shaft 9) has a shoulder 11.

pressed by a spring 13 down againstthis The ring 12.is capableof movingvertically up and down along the shaft 8, but is not capable of rotating rcla- A. ring 12 is tively to the shaft. A nut 14 is provided for pressing the collar 12 against the shouh dear 11 with adjustable force, the spring 13 beingtensioned more or less as required by screwing down the nut 11. The feeler lever 10 is loose, and capable of rotation on the shaft 8, but as the spring 13 exerts a pressure upon the feelcr lever 10,the latter is compelled to swing to and fro in an arc of a circle when the shaft Sis rotated to and fro. But if theend of the lever 10, strikes against any object, the shaft 8 can continue its rotation without compelling the lever 10 to overcome: the obstacle. The movement of the leverlO, is thus effected by means of friction between the parts 11 and 12. At every working movement of the machine, the shaft 8 (as well as the shaft 9) is rotated forward and backward through a determined angle. 1

Just above the J'rroqlnnd card 1 there is provided an arc'shaped guide 15 in which a. small light slide 16 can be moved to and fro. This slide carries a horizontal pin 17 and a vertical part 18. As shown in F ig. 5, the lower end of this vertical part 18 is slightly beveled. A very weak sensitive spring .19. (Fig. 5) has a tendency to keep the part 18 down with slight force, so that the part 18 must share this to and fro swinging movement.

The card 1 is provided at determined points with small punched elongated holes or slots 21 (pattern holes) situated exactly 1 in the path of the part 18. Vvhen the lever 10 moves in the direction of the arrow J and in this movement the part 18 meets one of the holes 21 it snaps into this hole and the feeler lever 10 can no longer-rotate. Butvas the holes 21 are so small that the part '13 cannot sink down wholly in them, the lever 10 is able to rotate back again without hindrance in the opposite direction of rotation on the next movement of'the shaft 8. As shown in Fig. 5, the end of the part 18 is beveled and the said part will therefore spring out again from the small hole '21 in which its point had sunk.

The following mechanism is now employed for the purpose of enabling the lever 10, which has been adjusted to the very slight resistance offered by the edge of the hole 21 in the card, to resist the much greater force which is necessary for the purpose of moving the embroidery frame that weighs from about 400 to 500 kilogs. For this purpose the small slide 16 is clamped by means of an ecc entric device in the position into which it has been brought by the feeler lever 10. This is shown more particularly in Figs. 6 to 9.

The slide 16 is provided with a strip 22 that is bent upwardly and rearwardly in,

such a manner that it is situated just above the resisting plate 23, and just below a block 24. The block 24 can move vertically up .and down relatively to the plate 23, so that the strip 22 can be clamped in it, as it were in a vise. This up and down movement of the block is produced as follows: The block is perforated with a cylindrical hole throughout its length, and'in this hole is a roll 25 with eccentric trunnions 26 and 27. When the roll is rotated on its trunnions 26, 27,- the block 24 is moved down, and grips the strip 22. The under surface of the block 24 is roughened like a file, and is hardened; this increases the security of the grip on the strip The eccentric roll 23, receives its rotation from a lever 28 which is fixed on its trunnion 27, and the upward movement of which is limited by striking against the lever 29, and is acted upon by a spring30 which has a tendency to draw the levers 28 and 29 constantly toward each other. The lever 29 is connected rigidly by its shaft 31 with a second lever 32, to which is pivoted a rod 33. This rod 33, as shown in Fig. 1, is operated by a lever 34 which receives at the proper moment a slight up and down motion from the main driving mechanism through the medium of a shaft 35. The rod 33 is not connected directly to the lever 28, and it receives its motion indi rectly through the lever 29 for a purpose hereinafter described.

On the vertical pin 36 there is mounted a rocking lever 37, the right hand of which carries a vertical bolt 38, and an inwardly "bent arm The lever 37 is hereinafter re- 'hereinbefore mentioned strip 22 and the latter'is clamped in positionby the eccentric block 24.

The striking of the adjusting arm 39 against the fixed strip 22 is effected by means of a small bolt 41 (Figs. 2, and 6) which is capable of vertical movement in the adjusting arm. This bolt 41 is held up from below by a small weak spring 42, and is influenced further by the fact that it is provided at its rear side with a slot 43 into which the front arc-shaped edge of a plate 44 engages. The edge is made arcshaped because the bolt 41 whose slot is intended to move along the said edge, is mounted to swing on a pin 36 as a center. front edge of the plate 44 has thus the form of an arc of a circle described from the cen ter 36. It may be stated, by the way, that I the small slide v16 is'likewise guided in an arc of a circle in its path 15, which path is also described from the pinj36 as a center. This would. appear at first'glance to be a contradiction, because the lever 10 which moves theslide 16 to and fro, swings on another center, namely, the center 3. But the deviation of these two circular paths from each other is equalized by the fact that the pin 17 is made of suitable length, and is loosely embraced by the fork 20, so that as the lever 10 oscillates, the fork 20 will shift to a slight extent on the pin 17.

The up and down movement of the bolt 41 is effected through the medium of the here inbefore referred to driving mechanism 33, 32,31, to which the peculiar lever arrangement 29, 28, is also connected. The aforesaid plate 44is fixed on the same shaft 31, namely, the shaft on which the two lovers 29 and 32 are rigidly fixed. Thus in whatever point of its path the bolt 41 may be situated, the'said bolt, by reason of its engagement'through the slot 43 with the plate 44, will. always be raised and lowered at the same moment as the strip 22 1s released and gripped again. But it is to be noted that The said the bolt 41 will always be raised just before, that is to say, will be released from itscontact with the strip 22, before thestrip 22 itself is released out of its clamped position. The reason is that this release takes place only when the lever 28 is pressed completely down, so as to allow the eccentric roll 25 to act.

As already above indicated the bolt 38 is movable to and fro in an arcuate guide. This arc-shaped guide 40 occupies the position shown in Fig. 2 only at the moment when the bolt 38 is to be movedto and fro or is fixed in the said guide. In other respects it forms the upper part of a vertical shaft (Figs. 1, 8 and 9) which can be rocked to and fro through about 90, by the very powerful force of the driving gear of the machine. This driving gear consists of a lever, 46, fixed on the shaft,45, a connecting rod, 47, and a slide, 48, of sufficiently strong construction. 49 is the main shaft of the machine, on which are fixed a large number of cams among which are the two cams, 50 and 51. Rollers, 52 and 53 are pivoted on the slide, 48, the periphery of the cam, 50, being always in contact with the roller, 52, and that of the cam, 51, with the roller 53. Therefore when the main shaft, 49, rotates uniformly, the slide, 48, will be caused by the cams 50, 51, to move to and fro or to remain stationary at intervals. In the same way are produced the to-and-fro rocking movements of the shaft, 45, and of the guide, 40, which is rigidly fixed thereto.

In the position of the parts shown in Fig. 2, the bolt, 38, is actually central with the shaft, 45. This is the basic position into which the lever, 37, is adjusted on every working movement of the machine, by means of a driving mechanism hereinafter described. But if the lever, 37, is rocked to such an extent outward that its bolt, 41, strikes against the strip, 22, then the bolt, 38, assumes a position within its guide, 40, which is situated at a greater or less distance from the said basic position. \Vhen this shaft, 45, with the guide, 40, has rocked in the direction of the arrow J (Fig.2) the lever, 37, which has up till then acted as an adjusting lever, now acts like a connecting rod and pushes back the bolt, 36, and all the parts connected with it to a corresponding extent: This movement of the bolt, 36, in the direction of the arrow K (Figs. 1, and

2) is the movement, which is hereinafter de- 1 scribed, serves for moving the embroidery frame from stitch to stitch. The i great pushing force produced by the cams, 50, 51,

enables the said movement to move the great heavy mass of the embroidering frame, al- I though the weak lever, 10, which serves to limit this movement, has only struck against the edge of the hole, 21, in the jacquard card 1.

In the same way as the small part, 18, is held temporarily in its position by the clamping of the strip, 22, a similar process takes place with the much larger bolt, 38. The bolt, 38, (see Figs. 8 and 9) forms the upper part of a link block, 54, which is guided in a circle in the guide 40, an eccens tric roll, 55, acting against the lower edge of the said link block. The lever, 59, which is fixed on the journal, 57, serves to rotate to andfro the eccentric roll, 55, which is rotatably mounted with its journals, 56, 57 in the head, 58, of the shaft, 45. The arm, 60, shown in Figs. 1, and 2, is not a movable lever, but it is fixed to or formed in one piece with the head, 58, and it has merely the object of enabling the spring, 61, to be hung, which spring is put under tension when lever 59 and therefore also the eccen-, tric roll are rotated to the right, by the lever 59 being moved away relatively to the arm 60 by the screw stop 62. The eccentric roll 55 is thereby released and the bolt 38 is freed for the purpose of being shifted, so long as the stop 62 forces back the lever59, as shown in Fig. 1. But when the lever 59 is freeto follow the pull of its spring 61, it brakes and holds fast the bolt 38 wherever the latter may be situated in its guide 40.

In thediagrammatic Fig. 10, 63, 64, 65, indicate the framing of a shuttle embroidering machine, in which the embroidery frame 66, 67, 68 is suspended in the ordinary manner so as to be capableiof moving in all directions in its own vertical plane. The frame is balanced by means of counterweights. In an ordinary shuttle embroidering machine this embroidery frame 66, 67, 68, is moved to and fro by means of a pantograph by the hand of the operator, but in the present case two shafts,namely, a vertical shaft 69 and a horizontal shaft 70 are em ployed for the same purpose, and are caused by the hereinbefore described mechanism to rotateto and fro. In these movements a pinion 71, fixed on a shaft 69, gears with a horizontally movable rack 72 having on its left end a guide 73.

On the embroidery frame 66, 67, 68, there isfixed a triangular arm 74 carrying a uide pin 75. "The pin 75 engages in the guide 73. On the shaft70 there is also fixed a pinion 76, which engages with the rack 77, that can move vertically up and down. On the upper end of the rack 77 is provided the guide 78, in which there also engages the aforesaid pin 7 5. i

Assumingthat the shaft 70 is held fast for a moment, that is to say, it does not rotate, and that the shaft 69 rotates through a certain angle, then the pin 75 will be moved in a horizontal direction by the guide 73 through the medium of the toothed wheel gearing 71, 72, and consequently the whole embroidery frame 66, 67, 68, must share this 5 itself no vertical movement. Now if on the other hand, the shaft 69 be held fast for a moment, and the shaft 70 be rotated, then the pin 7 5 and consequently the entire embroidery frame will only move vertically up and down, and the pin 7 5 will slide in the vertical guide 73. If the two shafts 69 and 70, are rotated simultaneously, then obviouslv the pin will be guided by the two guides 7 3 and 78 in an oblique direction, and the embroidery frame 66, 67, 68, will move in this oblique direction. Thus, the angles of rotation and the direction of rotation of the two shafts 69, 70 will always determine the movement of the embroidery frame in any direction, horizontal, vertical, or oblique.

Referring to Figs. 1 and 2, it is to be noted that the holes 21, in one half of the jacquard card 1, have the function of regulating the movements of the vertical shaft 69 for the horizontal movements of the embroidery frame, and that the holes 21 in the other half of the jacquard card have the function of regulating the movements of the horizontal shaft 70 for the vertical movements of the embroidery frame. For this reason all parts are provided in duplicate and arranged symmetrically in Fig. 2 as already stated, although not all the parts are shown in that figure for the sake of simplifying the drawings. Obviously, the mounting and drive of the two shafts 69 and 70, constitute exceptions from the symmetrical. arrangement. This drive is as follows :and will now be described first in the case of the vertical shaft 69 for producing the horizontal movements of the embroidery frame :-The pin 36 which, as already above stated is moved horizontally to and fro, causes a corresponding to and fro movement of a slide 79, 80, 81, 82. The said slide is guided in a horizontal straight line by any suitable means. On the shaft 69, there is fixed a disk 83 against the periphery of which, the slideways 8% and can be pressed alternately means of an eccentric roller 86. These slideways are adapted to rock through a very small angle on their pins 79, 80, and are connected together by means of acoupling link 87. Then, as as sumed in Fig. 2, the slideway 84: is pressed against the friction disk 88, that is to say, the slideway 85 is free, and the pin 36 moves in the direction of the arrow H, the shaft 69 will be rotated to the right. and the cmbroidery frame 66, 67, '68, (Fig. 10) will move horizontally in the corresponding di rection. But if instead of the slideway 84:, the slideway 85 is pressed by the eccentric roller 86 against the periphery of the disk 83, then the pin 36 is moving in the direction of the arrow K, the shaft 69 will rotate in the opposite direction, that is to say, to the left.

Exactly the same driving mechanism as that just described (88, 84, 85, 86) is also provided for driving the horizontal shaft 70, that is to say for producing the vertical movements of the embroidery frame. This driving apparatus is indicated in Fig. 1 by 83, 84, 85', 86. Both the driving mechanisms differ from each other only by the fact that they are turned through an angle of relatively to each other. The driving of the eccentric roller 86 will be hereinafter described.

On the main shaft 19 there are fixed a large number of eccentrics of which these 50, 51, have already been referred to. The other eccentrics are not shown in order to prevent overcrowding of the drawing. On the periphery of one of these eccentrics that are not shown, there works the roller 88, which is pivoted in the lever 89 and can rock on the shaft 90. On this shaft 90 is also fixed the forked lever 91, 92. 91 is the lever on which the screw stop 62 is mounted. The lever 92 is provided with a nose designed to work against a hook 93 which forms the end of an arm 94. This arm at forms a part of the hereinbefore mentioned slide to which the pin 36 belongs. The engagement between the lever 92 and the hook 93 is to compel the pin 36 to move exactly into the terminal point of its horizontal path (if it should not be there already) at a certain moment of the operation of the machine. This terminal point of the path forms at the same time the exact rocking center of the arc-shaped guide 10, along which the bolt 38 must be guided. But when the pin 36 has been secured at this center by the engagement of the parts 92, 93, the lever 91 has also depressed the lever 59, that is to say, the eccentric roll 55, (Figs. 8 and 9) has released the bolt 38 which'can now slide along the slideway 40 until the bolt 41 strikes against the strip 22. I shall now pro ceed to describe how this rocking movement of the bolt 38 on the center 36 can take place in such a manner that it will cease when the part 41 strikes against the part 22. This is effected in the same manner as already described. with reference to the feeler lever 10, which had to be suddenly held in a variable point of its path namely, by frictional drive. The lever 37 which rocks on the pin 36 and the outer end of which carries the bolt 38 and the adjusting arm 39 with the bolt 41, forms one rigid piece with the lever 95. This lever 95 carries at its end a leather covered :pair of tongs 96, 97, (Fig. 1), which are held together by spring pressure and which hold a straight rod 98. The rod 98 is connected by a universal joint with the lever 99, which is fixed on the shaft 100. The shaft 100 is rocked bymeans of an eccentric on the main shaft 19, forward at one moment, and backward at another moment. The bell crank lever 95, 37, which rocks on the pin 36 will therefore also be compelled generally to follow the drive of the lever 99. But from the moment that the bolt 41 strikes against the strip 22, this drive ceases, and the leather covered tongs 96, 97, slip along the rod 98 during the remainder of the movement of the lever 99. j a

I shall now proceed to describe how the above mentioned eccentric rollers 86, and 86' are rotated in one or the other direction, in

. order that at one time the slideway 84.- and at another time the slideway shall be pressed against a friction disk 83. This drive must obviously also be regulated by means of the jacquard card 1. For this purpose there are punched in the jacquard card at certain places holes 101, whichserve to allow of the passage of a small nose 102 (Fig. 3). On: each stroke this nose 102 is pressed by the hereinafter described mechanism, with very small force in an upward j direction. If in this upward movement the nose does not meet any hole 101, in the card, it remains down, and therefore does not produce the action which would cause a rotation oftheeccentric roller 86.

Between the rolls 3and 4, there is arranged a stationary table 103. The jacouard card 1, moves closely over this table. Below the table 103 and near the two edges of the jacquard card there is arranged a plate 105 which rocks on the pin 104, and is provided at the top with the nose 102 and rests at bottom on a small lever 106, rocking on the pin 107. By means of a mechanism which is moved byone of the eccentrics mounted on the main shaft 49, there is moved a pin 108 to and. fro in a horizontal direction at each working stroke.

The pin 108 is in contact on one side with the lever 106, and on the other side with a weak, spring 109 fixed to the lever 106. If now, the pin 108 (Fig. 3) moves to the right, it carries with it the lever 106, the upper end of which strikes against the nose 110 of the plate 105, whereby the nose 102Eis compelled to move down that is to say, to move out of the hole 101 in the jacquard card.

But if the pin 108 is moved to the left in Fig. 3, two things can happen. If the nose 102 meets with a hole in the jacquard card, then thelever. 106 is compelled by the small spring 109 to follow this movement of the pin 108 to the left, and it pushes up the plate 105 so that the nose 102 passes throughthe hole in the card. Or, if the nose 102does not meet with a hole in the card, then the lever 106 is unable to move the plate. 105 upward, that is to say,.the lever 106 remains d. t e pr ea e s be ei tl upper end of the lever 106 meets with resistance from the plate 105 as shown in Fig. 12..

When the pin 108 is moved from the position shown in Figs. 3 and 11, toward the right back into its normal position, then it moves the lever l06with it, and the upper end of the lever 106 strikes against thenose 110 of the plate 105, forces it back and thereby compels the nose 102 tomove down again out of the hole of the jacquard card 1.

A rod 111 is moved at each working stroke once horizontally to and fro in the direction of its own length, exactly in the direction in which the nose 102 appears now and again over the top of the jacquard card 1. If in this case the front end of the rod 111, meets the projecting nose 102, it strikes against it and connot move any farther. If on the other hand it does not meet it, that is to say, the nose 102 is not projecting through the jacquard card, then the rod 111 will continue its full stroke without hindrance. the hindering of its movement by means of the nose 102 takes place as already indicated above, for the purpose of operating the eccentric rollers 86, 86 shown in Figs. 1, and 2, in such a manner that the right and left hand rotary movements of the vertical shaft 69. shall be guided in accordance with the design to produce the horizontal movements of the embroidery frame, and the right and lefthand rotary movements of the horizontal shaft 70 shall be guided in accordance with the design to produce the vertical movements of the embroidery frame.

I shall now describe the driving mecha nism for producing the to-and-fro movements of the rod 111, and the transmission of the movements to the eccentric rollers 86 and 86.

In the front part of the framing of the machine there are mounted two shafts 112 and 113 .(Figs. 2,11 and 12). On the shaft 112 is fixed a lever 114, on the free end which there is mounted the roller 11.5, which is assumed to bear on the periphery of an eccentric that is fixed on the main shaft 19 (Fig. 1). On the shaft. 112, there is fur ther fixed a lever, 116, with a roller, 117.

A three armed lever in which are arranged pivoting bolts, 118, 119,120, is rotatably mounted loose on the shaft, 112. On the shaft, 113, there is also similarly mounted a two armed lever provided with pivotingbolts, 121, 122. The two pivoting bolts, 119, 122, are movably jointed together by means. of athree armed connecting piece. It is to be understood that only one of the bolts 118 and 123 is in use at the same time, the other being removed to leave the parts disconnected. A connecting rod, 124:, is provided likewise with two bolt holes, 118 and 123 for insertion of bolts 11S and 123, and this we serves to make a connection with Thismovement of the rod 111 and the eccentric roller, 86 (Figs. 1 and 2). According as the pivoting bolt is inserted into the hole 118, or into the hole123, then, at a determined movement of the mechanism shown in Figs. 11 and 12, the connecting rod, 1% is moved to and fro in oneor the other direction, and consequently either the slideWay, 84, or the slideiva v, 85, is pressed against the periphery of the roller, 83, an'd reduces righthand or left hand rotations of the shaft, 391 Another connecting rod, 12 1, (Figs. 1 and 2), making connection with the eccentric roller, 86, and acting in a similar manner as the rod, 124:, serves to cause either the slide'vvay, 84', or the slide- Way, to be pressed against the periphery of the roller, 83, for producing right hand or left hand rotations of the shaft, 7 0'.

V In theiront upper part of the framing of the machine there is mounted a shaft, 125, shown in Figs, 1, 2, 11, 12, 14, 15. By means of a lever and eccentric (not shown in the drawings) Worked from the main shaft 49', the shaft, 125, rocked to and." fro through a small angle once at a certain momenton each working stroke, so" that the two levers, 126, Which are, Immuni ies and left in the machine on the shaft, 125, are moved once up and dovvirat' eaeh Working stroke. The free ends of the tvvo levers, 126, are con'nected together by a rod, 127.

Two verticalconnecti'ng rods, 128 and 129', are each provided at their upper end with a semi-circular recess by which the said rods can be alternately hung onto or coupled With the rod, 127. In Figs. 1, 11 and 1 1 the rod, 128, is shown by wa of ejia mpl'e hung" onto the rod, 127. In Figs. 12 and 15 the rod, 129, is shown so coupled. Noni Whichever rod (128 or 129) is hungonto the rod, 127, that rod must follow the movement of the lever, 126. The fact which of the two rods,

128 01'129, is to he coupled toithe" rod, 127,

is controlled by the rod, 111 coiip erating with the nose, 102, which projects new and then above the surface of the jacqhaed card, 1. g V, I v M The rod, 111, is movably connected By means of the pivoting ,loolt, 13 0," to the rod,

128, and the rod, 129, is pulled by a sprin 131, toward the rod, 128, a certain distance between the rod, 128, and the ro 'd,129,- being maintaine'd by means of mesa-13 2, on the rod, 129. .A sprin 133, pulls the rod, 128,

to the left until the slideway 13%; arranged I on rod 128strikes against the roller 117 of thelever116. I I

The operation is somewhat as follo' i'vslf v At each Working stroke the lever 11.6" fnoves once for a short distance to the left to the right. The levers 1235M 129 are caused b follow this left and right movement or the lever 116, when the nose 102' isnot p'rdj et: irig up through the jacquard can 1. But

3 the two springs 133",. to

irate nose 102 does so pra se, the an: n strikes against the nose and in opposition to the spring 133, prevents the lever 128 from following the movement of the lever rod 128 remains down, v vhile the rod 129 is drawn up. This position of the parts is shown in Fig. 15. g

In the aforegoin description it has been assumed that the pivoting belt 123 was inserted in the hole 123. But if the pivoti ng belt 118' was inserted in its pivoting hole 118, then the same movements as described in reference to Figs. 14 and 15 Will take place with the result shown in Figs. 16 and 17. he difference consists obviously in the am that therod,1'2-1in Fig. 1,ismal2ing 14;, and is' malring" in Fig. 17, the opposite movement to that Fig. 15. It will there: fore be understood that when, for example, it is desired to embroider a design such as that indicated at (i in 13', inthe shown and in the symmetrical but dppesite Way 7), is merely necessary to insert the aforesaid pivoting bolt at one time at 118 and at the other amen 123', into the pivotmg joint, on the side of the' machine con aomngtte horizontal movement's" of the embroidery frame,- the vertical niovefnents of the lease remaining unaltered.

The design (Z is obtained by reversing the vertical movements of the frame Without reversing its horizontal movements and the design c loy' reversing both the vertical and the horiiontal movements of the frame. 7 By these means it is thus poss'ihleto embroider oa' and the same design in" our different} positions from a single ja quard card, that is" to say, a jacqiiard card which has been uaeheaoaiy with one assign.

I-IWing now, particularly described and tion, and tepetfwmed, I declare that What I elaini 1's: v

1. emhroidering machine comprising in combination, a jacquard, an embroideri'ng frame, devices connected With said frame and adapted to shift the same in" a plu-' rality oi different directions, and drivenni'eelianism ontrolled by" the jacquard and connected ivith s ai-d devices and including ashifting and" rocking levef having a fi iied the opposite movement to that shown in Fig.-

rot

aseertained the nature my said inveain. What manner the same is to rat ans, 'aii adjusting lever. ea; transmitting its motion to said frame, and means controlled by the acquard for anchoring said ad ustlng lever to said rocking lever at any desired distance from the rocking axis thereof, substantially as described.

2. An embroidering machineacomprising in combination, a jacquard, an embroidering frame, devices connected with said frame and adapted to shift the same in a plurality of different directions, driven mechanism controlled by the jacquard and connected With said devices and including a rocking lever having aafixed axis, an adjusting 1evar for transmitting motion to said frame,

and means controlled by the jacquard for 15 anchoring said adjustinglever to said rockmg lever at any desired distance from the rocking axis thereof, substantially as :de-

scribed.

In testimony whereof I affix my signature 20 Copies of this patent may be obtained for five cents each, by addressing the Commissioner of IE'atents, Washington, 110.
