To all who-m it may concern:

Be it'known that I, Ronnn'r ZAHn, a sub-' ject of the Emperor of Gern'iany, residing at Plauc'n, in the Kingdom of Saxony and Em pire of Germany, have invented certain new and useful Improvements in Card-Punching and Emhroidcring Machines, of which the following is a specification.--

The jacquard card re uired for theoperation of an automatic shuttle embroidering machine,-has hitherto beenproduced with much labor and loss of time by means of a separate card punching machine. worked by hand. Since from the arrangement or dis-u tribution of' the" holes punched in the jacquard card it is not possible to get the faintest idea, of how .the embroidery design W111 look which will 'be produced by the em broidering machine when using the particu* lar card, a special or auxiliary embroiderlng machine containing only about two to four needles with as many shuttlesfhas' been required, in order to allow ofproduction of a sample embroiderydesign. This special em-.

broidcringmachine has been arranged at the side of the card punching machine and ha's'had its small embroidery frame coupled to the card punching machine, insuch a,

manner that as the card is being punched, a sample of the embroidery design is pro" duced, which sample served to showwhether or not the punched card clorrespondswith the designed pattern. In operating such sary after each punching operation to turn around the small shaft of the auxiliary embroidering machine, whereby each time a single stitch Was'produced. Thereupon, the punching machinehas been adjusted for the punching of the next .hole and the shaft of the auxiliary embroidering machine has been given another turn for the production -of another stitch and so forth. This manipulation had to be repeated until the entire design was ready, As already stated, the production of a jacquard card inthis manner has taken several hours and with larger designs even'a whole day and, with all this labor and expenseionly a reduced design-has been produced that could not serve any other purpose but to verify 'the correctness or; accuracy of the produGBd' jacquard card.

shuttle embroidering machine, whereby J ac.-

- quard cards are produced'without any addi tional labor, expense and any loss of'time. The i1 1venti0n-'may be applied to embroidering machines controlled bya pantograph or to such of the automatic type. In the The present inventionhas for its object I to provide a combination card'punching and first case, that is to say, when an embroide'rdesigned embroidery pattern. For, since embroideries of'a total length of fifteen to iing machine controlled by a pantograph is used, there is the advantage that it is possible to easily ascertain the value of a newly I twenty meters can be produced on embroid-' ery machines of ordinary size, this; length willbe quite sufiicient to allow of the produced einbroidery'bein cut up into a great number of samples proved or is not salable, the-loss caused by the cutting up of the embroidery is not on the distribution 'amongi'customers. If the design is not apgreat, because. the latter has been produced almost without expense, excepting the cost of them'aterial. If, on the other hand, the new design proves to be easily salable, the manufacturer can at once without the slightest loss of time, fill the orders that come in,

even if urgent, because the jacquard card is already at hand and ready for use on the embroide'ring machine. This constitutes the great economical value and the technical.

progress afforded by the present invention. J In thecase ofan automatic embroidering 1 machine when joined with a-card punchingmachine the latter will serve as a substitute fora jacquardcard copyingmachine and will allow of a largenumber .of jac uard car'dsof the desired design being pro uced I in a very short time so that "anunlimited' number of orders can be quickly filled.

To make my invention more clear, the

drawing, in which similar reference numerwhichj Figure 1 1s anelevation of an embroiderthrough-shaft 280f1Fig. 1- and 4 is a intersection through Fig.3.

"same is illustrated in; the accompanying 'als denote corresponding parts and in In the drawing, which forms a part of this specification, the parts 1, 2 and 3 rep resent the left hand end of the frame of a shuttle embroidering machine which may be of ordinary construction.

6 is the board to which the pattern of the embroidery design is fixed and which by means of the arms at and is secured to the machine frame: The large embroidering or fabric frame 7 8 and 9 is guided by means of the pantograph 10, the pointer 11 of which is guided as in every ordinary shuttle embroider-lug machine, along the lines of the pattern fixed to the board (5. For the purpose of operating the card punching machine, hereinafter specified, the pointer 11 also engages twoloops or guides 12, 13 that are arranged crosswise and at right angles to each other. The guide 12 is rectilinearly guided with least po sible friction by means of bearings 14. 15 and the guide .13 is similarly guided by means of bearings 16, 17. Then the pointer 11,- is moved along horizontal line, the guide 19 remains stationary and the guide 13 only sharesthis movement. The reverse takes place when the pointer 11 is moved along a vertical line. hen, however, the pointer 11 is moved along an in-- clined or curved line, then both guides 12 and 13 will be compelled to move sin'mltaneously in one or the other direction. All these movements of the two guides 12 and 13 are utilized for the purpose of swinging two perforating punches 18 and 19 over the paper strip 20 around their fulcrums 22. The paper strip 20 is slowly fed step by step in the direction of the arrow 21 by suitable means (not shown), while the two punches 18 and 19 by the mechanism shown in l ig. 2 are caused at each step to punch two holes in the paper strip 20.

Since the mechanism shown in Fig. 1 for transmitting motion from the part 19) to the part- 13, is exactly the same as that for trans init ting motion from the part 13 to the part 19, it will be suflicicnt for the understanding of this invention to describe in detail only one of these two mechanisms.

Each punch is arranged. as will be hereinafter s iecitied. in a lever or arm 23. which is pivoted to the fixed pin 29 and the free end 24 of which is curved in a. circle l1 aving as its center the pin 22. The lever 23 is rigidly connected to .a toothed segment 25. A rack 26 enga gcs on one side with the teeth of the said segment and on the other side with the teeth of a gear 97. liy this means, the lever 23 is positively connected to the shaft 28 on which the toothed wheel 27 is fixed, that is to say. to every position assumed by the toothcdwhcel 27 in its rotation, a definite position of the punch 19 over or in front of the paper strip 29 is obtained. Fixed on the shaft. 23 is also a smooth disk 29 against the periphery of which a smooth bar 30 guided in a sleeve secured to or formed integrally with a slide 32, is pressed by means of a powerful spring31. The said spring exerts sufiicient pressure between the said bar 30 and the disk 29 to cause the latter to swing back and forth is the bar 30 is being reciprocated in a straight line. The bar 30 is pivotally connected at 34: to a cross piece of the guide 13, and consequently all the movements of the latter will be transmitted to the perforating punches 18, 19,. and thus to every position assumed by the guide 13 inits movements in front of the pattern board 9, a definite position of the punch 19 over the paper strip 20 will correspond.

The slide 32, which is mounted in a. hearing 33 and which is acted upon by the spring 31 to prcssa bar 30 against a friction wheel 29 is pivotally connected by means of a bell crank lever rod 36 and a three armed lever 37 to the slide 32. The said three armed lever 37 carries a roller 38 which travels on the periphery of, a cam 39 fixed on the shaft 0. This shaft- 40 is so operativcly connected to the main shaft '61 that by the high portion thereof the roller 38 is moved in the direction of the arrow 41, whereby the bars 30 and 31 are drawn away from the friction wheels 29 and 99, and this disconnection is maintained until the cmbroidering needles are withdrawn, from the fabric. that is to say, until the high portion of the cam 39 has disengaged the roller 38. 1

As will be seen by reference to Figs. 1 and 2, the curved ends 91 of the arms 23 are bifurcated and extend on opposite sides of the material 20. The punches 18 and 19 are slidably mounted in one portion of the fork of each arm. Springs 57 mounted on the fork portions l t normally hold the punches 18. 19 upwardly in theirv hearings. A member 59 engages the outer ends of the punches 19 and 19 and is actuated by a cam 53, so as to depress the punches 'when the same have been properly positioned abreast of the material 20. The shaft of the cam 58 by suitable means (not shown) is so con nected tothe main shaft (31 of the embroidcring machine, that the punches 18 and 19 will enter the strip 90 synchronously with the entrance of the needles into the fabric. After the punches have entered the material 20 the arms 23 must be retracted to their 45 abut against the bearings 42 and 43 respectively. The innerend' of the sleeve 44- 1s provided with a disk 46 which carries an abutment or lug 53 (Fig. 4). and which is provided with a shoulder 52 (Figs. 3 and 4)."

The inner end ofthesleeve 45 is provided with a disk .47 which carries an abutment or lug 51 (Fig. 4) and is providedwith a shoulder 50 igs. 3- and 4). Theshoulders 50 and 52 face in-oppositedirec'tions and en-v gage a fixed'abiitment 54 (Fig. 4).. .The. 1 sleeve 45 isprovided with a spring 56 which normally maintains the shoulder50j in engagementwith' the fixed abutment 54. The sleeve 44 is provided with as ring 55 which normally maintains the shoulder 52 in'engagement with the abutment 54. The shoulders'50 and 52 engage on opposite sides of.

' the abut-mentand the s rings 55 nd 56 'are' .shoulders'50'and 52 the lugs 5'3 and 51 engage on opposite sides 'of the.

to normally maintensioned and a tain the shoulders 0% the disks in engage" ment with the abutment 54.. Opposite the or abutments lug 49 secured to a col ar 48 which 'is' fast on the'shaft 28. It will be-understood that the same construction is used for the shaft of the friction wheel 29'. v When the member 30 is moved in one direction and is in contact with the friction Wheel 29, one of the s ri s 55,56 will be tensioned and one oft e s eeves 44, 45 will. be moved under the action of the springto position the punch 19. As soon as the bar 30 has been withdrawn fxinn the engagement with the wheel-29 suc spring will return the shaft; 28 and arms 23 to a normal position. Movement of the member 30 in another direction will muse a like'op'eration of the other sleeve and spring.
