ELECTRICAL PATTERN F012 THE MANUFACTURE or J'ACQUARD-CARDS.

Application filed January 9, 1908.

Specification of Letters Patent;

T 0 all whom it may concern:

Be it known that I, PAUL'WEIssE BoRN, a citizen of the German Empire, residing at Bar-men, in the Province of Rhenish Prussia and Kingdom of Prussia, Germany, have invented certain new and useful Improvements in Electrical Patterns for the Mannfacture of Jacquard-Cards, of which the following is a specification.

The subject-matter of this application is a new electrical pattern for card-punching machines, which is intended to be employed particularly for manufacturing jacquard cards for weaving name-ribbons, numberribbons and other patterned fabrics or fancy cloths. In the manufacture of said fabrics it has hitherto been necessary first of all for a pattern-drawing to be prepared for each design according to which drawing the jacquard cards have then been punched out on a card-punching machine, an electrical pattern specially prepared therefor according to the drawing being used if desired.

The peculiarity of the new pattern consists in this, that in correspondence with the figure (name or the like) to be woven the pattern is composed of separate individual or unit patterns or letters, figures or other signs or portions of designs which are adapted to be used over again, and in these unit patterns being united to form the complete pattern by being mounted side by side on a bed of electrically conductive rails or wires arranged side by side, their number corresponding with that of the warp threads in the fabric to be manufactured, said rails or wires being connected each with a conductor controlling by means of an electromag net the striking lifting-wire appertaining thereto. The unit pat-terns may thereby themselves be formed as electrical patterns and be so shaped that the conductive surfaces on being mounted on the above-mentioned bed come into electrical connection with the rail on the bed corresponding to the respective warp thread of the fabric to be manufactured. Instead of this, however, when unit patterns consisting of non-conductive material are used, these patterns may be provided with perforations corresponding to the design, through which perforations the wires or rails of the filOOVQ-IDOH- t-ioned bed are then accessible. Consequently in the case of this invention it is not necessary to make a new pattern or a new drawing for a new name nor a new electrical pattern corresponding to such new name or figure, but the electrical pattern is simply composed of unit patterns kept in stock. Consequently a very considerable amount of time and wages is saved, particularly as the composition of the patterns does not require specially skilled workmen.

Two embodiments of the invention are illustrated by way of example in the accom panying drawing, in which:

Figure 1 illustrates in perspective the pattern composed of several parts according to the first method of carrying out the invention, said pattern being connected with the electric conductors, Fig. 2 an individual or unit pattern in plan, Fig. 3 a section of the same on the line AA of Fig. 2 and Fig. 4 a section on the line BB of Fig. 2. Fig. 5 illustrates in longitudinal section a pattern composed of three parts, said pattern being arranged on the rail-bed. Fig. 6 is a plan of the parts shown in Fig. 5, and Fig. 7 a cross section through said parts the unit patterns being shown raised above the rails. Fig. 8 is a plan of the second embodiment. Fig. 9 is a cross section through the same.

In the case of the first embodiment the unit patterns having the various letters or signs are arranged like the well-known strip patterns. They consist of a plate 1 of nonconductive material (hard-vulcanized india rubber (ebonite) or the like) which is shaped like a comb not only on its upper surface as in the case of previously known patterns but also on its under surface, that is, it possesses at both sides longitudinal grooves 2 and 3 respectively, the grooves on its under surface being deeper than those on its upper surface as is particularly evident in Figs. 3 and 7. The number of these grooves is equal to the number of the warp threads required for forming the design. The transverse divisions shown in Fig. 2 each correspond to one of the jacquard cards which are to be made and which are requisite for forming the individual letter. In order to form the conductive surfaces the small strip-shaped contact pieces 4 are inserted in the upper grooves 2 of the plate and are fastened by cement, for example, in such a manner that they project a little from the plate 1 but are insulated from one another by the ribs on said plate which are situated between them. These small contact pieces 4 extend over one,

two, or even more of the transverse fields of the plate 1 according as to whether at the place in question a hole is to be punched in one or in more successive jacquard cards. These contact pieces 4 might instead of being arranged as above extend over the whole length of the unit pattern and then according to the design be partially covered with insulating material as in the case of the above mentioned strip-patterns. These contact pieces 4 are electrically connected, by means of a wire 5 embedded in the plate 1, with the wires 6 lying at the bottom of the under grooves 3 which coincide with the upper grooves, said wiresextending along the whole length of said grooves. The unit patterns thus arranged have in this case such an external shape that they can be arranged close together in rows in any desired order so that thereby the pattern for a Whole word, several words, or the like, can be formed. For this purpose the unit patterns are arranged close to one another on a bed in the requisite order, which bed is formed of thin conductive rails or wires 7. These rails are arranged edgewise parallel and close to one another at a distance from one another corresponding exactly to the distance between the grooves 2 and 3 and are held in insulating supports 8 which in their turn are fastened on a foundation plate 9. The number of these rails or Wires 7 corresponds with the number of the warp threads of the fabric to be manufactured or of that of the lifting wires of the jacquard machine in question for which the cards are to be made. The unit patterns as already mentioned are mounted on these rails 7 and in particular on those which correspond with the warp threads cotiperating in the formation of the design and in such a manner that the rails 7 engage in the under grooves 3 of the plate 1 and consequently are in contact with the pieces of wire (3 lying at the bottom of these grooves, the contact being as much as possible over the whole length of said pieces of wire, so that thecontact' pieces a of the patterns are electrically connected with the corresponding rails 7. Each of these rails 7 is connected by means of a wire 10, in the course of which an electromagnet 11 is connected, with the one terminal of a suitable source 12 of current, the other terminal of which is connected by means of a wire 13 with a contact finger 14. The latter in the example illustrated is so arranged on a slide 15, which is moved by suitable means not shown in the drawing transversely to the rail 7, it being adapted to come to a standstill at the end position, that on each movement of the slide 15 its free end lightly passes over one of the transverse areas of the pattern. After each of these movements of the contact finger 14: the pattern is advanced through a distance equal, to one transverse division of the pattern by the displacement of the foundation plate 9 which carries the rail 7, in order that the contact finger 14 when performing its next movement may slide over the next area of the pattern. Instead of the above method however the same end may be attained by correspondingly movin the slide 15 together with the contact linger. As often as the contact finger 1a on moving over the pattern meets one of the contact pieces 4 the circuit of the corresponding wire is closed and consequently the electromagnet 11 situated in the circuit in question is excited whereby the needle mechanism of a card-punching machine, well known per se, is set.

The second embodiment which is illustrated in Figs. 8 and 9 is distinguished from is, to one of the jacquard cards which is to V be made and which is requisite for theformation of the individual figures. of the conductive surfaces on the unit patterns in the case of the first embodiment, in the case of this second embodiment the re spective areas of. the unit patterns are provided with a complete perforation 17 so that ranged properly on the bed 7, 8,9 the wires or rails 7 are accessible through these perforations 17 to the contact finger, While they are covered over at other places by the pattern. The contact finger is in thecase of this embodiment suitably guided by hand and formed like a style so that it-can be conveniently brought into contact through'the perforations 17 with the rails or wires. Otherwise the mode of operation is the'same as in the case of the first example.

In order to be able to keep the patterns 16 in a certain position on the bed 7, 8, 9 the patterns are suitably provided with ribs 18 so that they may be clamped firmly by means of the latter between the wires on rails 7 as can be seen in Fig. 9.
