SPECIFICATION forming Apart of Letters Patent N o. 781,167, dated January 31, 1905. Application filed July 30, 1900. Serial No. 25,317.

T cir/ZZ wher/L it Wto/,y concern:

Be it known that I, CARL VoRwERK, a subject of the German Emperor, residing at Barmen, Germany, have invented certain new and useful Improvements in Jacquard-Card Producing and Reading-In Apparatus; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to Figures of reference marked thereon, which form a part of this specification.

This invention relates to the art of producing cards for jacquard-operated machines; and it consists of means to operate a jacquard mechanism, said means adapted to have read in by hand the original design to operate the jacquard mechanism, so as to produce the first set of original cards which are either to be directly used in a weaving or other card-controlled fabric-making machine to weave a new design or are to be used in a repeating-machine, so that several sets of cards may be reproduced from them and of a new design or pattern.

Referring to the accompanying drawings, Figure 1, shows a portion of aweavers paper pattern. Figs. 2, 3, 4, and 5 show the four lower rows of squares of the pattern, Fig. l, separately. Figs. 2, 3, 4, and 5a are plan views of portions of reading-in perforated cards or plates, showing the four lower rows of squares of the pattern, Fig. 1, read in by means of movable pegs. Fig. 6 is afragmentary longitudinal section of the perforated card or plate with some of the pegs inserted and shown in elevation. Fig. 7 is a sectional elevation of a jacquard-controlled card-punching machine the selector-needles of which are to be controlled by a pegged card or plate, and Fig. 8 is a fragmentary elevation of a Jacquard loom the selector-needles of which are to be controlled by the pegged-in cards and whereby a read-in fabric is obtained for use in the card-punching machine instead of a punched card.

As is well known, the reading in and punching numerals.

ing of jacquard cards aspracticed before my invention is a very slow and laborious procedure; and my said invention has for its object the provision of means whereby these operations are very materially simplified and expedited and the expenses inherent thereto as materially reduced. This said object of my invention I attain by substituting for the readin fabric hitherto used a body provided with rows of holes or seats-properly arranged for the reception of pegs by means of which the pattern is read in. To this end one or more of the sides of the jacquardfcylinder may be made use of, as hereinafter referred to, though I prefer to use separate cards or plates having properly-arranged rows of seats or holes therein for the reception of the reading-in pegs and adapted to be mounted on the jacquard-card cylinder. Figs. 2 to 5 show each a portion of these cards or plates 19 partly read in by means of pegs 20, and Fig. 6 shows a part of such a plate and three of the removable pegs. In said Figs. 2 to 5a the read-in pegs are also indicated by an x. Pegs added, as in Fig. 3, are cross-lined, and the holes or seats from which pegs have been removed, Figs. 4u and 5, are indicated in solid black.

Fig. 2 shows the lowermost row of squares of the weavers pattern, Fig. 1, and Fig. 2 shows this row read in, each pegged-in transverse row, Fig. 2, corresponding with a given number of squares in the said lower row of such, Fig. 2, and are indicated by correspond- The same applies to Figs. 3 3, 4 4, and 5 5a for the next three successive rows of squares of the pattern, Fig. 1.

In view of the fact that usually but a single reading-in card or plate 19 is used, and as soon as this is read in the corresponding read-in fabric is woven or. the corresponding card punched it will be seen ata glance that in reading in the second lower row of the pattern, Fig. 3, only seven pegs 2O (shown by cross-lining) are to be added to the read-in card, Fig. 2, In reading in the next row of squares of the pattern six pegs only are added (also shown by cross-lining) and one peg is removed, as shown in solid black, and froml this thereading in of the next and any other row of squares of the pattern and the facility with which this reading in can be effected and the time and labor saved will be readily understood, while the cards and their pegs can be made use of for reading in any pattern, which is of course not the case with the read-in fabrics heretofore and still used, while a perfect control and supervision of the reading in of the cards can be exercised at all times.

In many fabrics which have regular crossweavings either in the design or figure or in the ground the reading in is materially facilitated by the use of a plurality of peg-plates.

In weaving satin fabrics, for instance, in which the design or figure has eight-leaved satin twill, while the ground is woven in taffeta, eight peg-plates are used, so that as a rule changes in the outlines only become necessary in the ninth card relatively to the first. The pegging for the ground, as well as for the design or figure cross-weaving, may thus in a great measure remain unaltered.

Inasmuch as the bindings are indicated on the cards or plates, mistakes in reading in can hardly occur.

In many other fabrics similar simplifications are possible, and in most cases the methodsl hitherto resorted to for simplifying the repeated punching of the pattern are avoided.

In patterns with many threads, where the peg-plates must'necessarily be very long, a plurality of short plates arranged side by side may be used.

As stated above and from what has been said, it will furthermore bc obvious that a pattern may be read in on one or more sides of the card-cylinder itself, though, as hereinbefore stated, I prefer separate peg cards or plates to be mounted on said cylinder. Inasmuch as the pegged card cylinder or the pegged cards are to be used for controlling the selector-needles of a jacquard, it will be furthermore perfectly obvious that it is immaterial whether said selector-needles are made to control the punches of a jacquard-card-punching machine or whether they are made to control the shed of a Jacquard loom, whereby a read-in fabric can be obtained, if such is desired, for use in the card-punching machine.

Of course it is more economical to control the punches of a jacquard-card-punching machine directly by the pegged-in cards; but in some cases it may be desirable to control them by a read-in fabric.

As shown in Fig. 7, the punches 13 of the punching-machine are attached to weighted wires 25, having an intermediate portion coiled into a spring 28, said wires being connected with the hooks 241 of a jacquard, as is usual in repeating card-punching machines. If now the pegged-in cards or plates 19 are placed upon the card-cylinder of the jacquard or a pegged -in-card cylinder is used and pressed against its selector-needles 23, the pegs 20 will displace their corresponding needles,

and the latter acting' upon their hooks will move them into the path of their respective griffs, thereby lifting the corresponding punches 13, and the latter will be struck by the striker -plate 17 to punch the card, as above described, the springs 28 serving to co'npensate the difference in the lift of the hook or griff frames 22 and the limited lift of the punches 13. In this mode of reading in and punching jacquard-cards one or two operators required to pull upon the lifted simple cords to lift their corresponding punches are dispensed with, as Well as the operator for the punching-machine, because the reader-in can perform this service, as will be readily understood.

Instead of proceeding as just above described the pegged-in cards or plates may be used in the jacquard for the production of a read-in fabric 10, Fig. 8, by the cooperation of the pegs 20, needles 23, and harness 25 of the jacquard upon the simple cords 1 to form the shed, said simple cords being wound on a beam 2 and winding on a beam 3, and by picking in the weft by means of a shuttle and beating the weft home by means of the batten or slay 26, as in weaving, a more uniform read-in web is obtained than is possible by reading in by hand, while the latter tedious and laborious mode of reading in is dispensed with. The read-in fabric is then used in the jacquardcard-punching machine in the usual manner.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

1. The combination with a jacquard mechanism to produce original selector-controllers for other jacquard mechanisms, of a peg-plate upon its cylinder and series of removable pegs adapted to operate jacquard selector-needles, whereby in changing the number or relation of the pegs, the same peg-plate can be used to produce various designs, substantially as described.

2. The combination with a jacquard mechanism, of a card-punching machine, of a pegplate on the cylinder of said mechanism and having as many holes as there are needles, and a series of removable pegs adapted to operate the needles, whereby in changing the number or relation ofthe pegs, the same peg-plate can be used to produce original cards for various designs, substantially as described.

3. The combination with a jacquard mechanism of a card-punching machine, of a pegplate on the cylinder of said mechanism and having as many holes as there are needles, and a series of headed removable pegs adapted to operate the needles, whereby in changing the number or relation of the pegs, the same pegplate can be used to produce successive original cards, substantially as described.
