ALBERT E. SCHMIDT in PHILADELPHIA. Double lifting jacquard machine.

Fatentirt in the German Empire from December 17, 1895.

According to the present invention, a jacquard machine is used, the number of sheets corresponds to half the number of jobs in the report, and in which each card only once for two Schufs.

This purpose is achieved by giving each card the pattern perforation, which corresponds to the entire knife cases, while the individual knife cases receive a two-stroke movement, in such a way that every time the card is touched all the plates of the various knife cases necessary for the relevant training adjusted and held and then lifted one after the other from the knife box concerned. To do this, one must prevent the sinkers of the second box from falling onto their associated knives while the first box is being raised fall back or can be moved back. This is what makes this desired effect it is achieved that immediately after setting the sinkers with the needles and the card stop, the ones to be lifted later Lifts knife boxes by a small amount, so that they do not close at the moment from these boxes lifting blanks can no longer fall back on the knives. This two-stroke movement the knife box can be made, as will be easily explained, by a slight modification the shape of the cam disks actuating the knife cases.

In order to better illustrate the invention, the mode of operation of the same is indicated schematically in the accompanying drawing. For the purposes of this illustration, two knife boxes A ¹ and A ^{2 are} intended, which are alternately raised and lowered in the known manner. The knives are marked with a ¹ and a ² , the needles with N and the sinkers with ft ¹ , h ² and ft ³ , the latter two ft ² and / ϊ ³ having the same height and being operated by the same knife case. The individual cards are provided with the perforations provided for both knife boxes, and the boards for both knife boxes are set at each card stop. The upper knife box A ¹ is first actuated, ie lifted. In order to prevent that the sinkers h ³ , which should not be actuated when the lower knife box A ² is lifted later, and that the needles N resp. the cards are pushed back in a known manner, fall back on the knife a ^{2 of} the lower box, this is raised at the same time with the upper box A ¹ by a small amount (by a corresponding modification of the shape of the cam used to drive the box), ie simultaneously with the upward movement of the knife box A ¹ , the knife box A ^{2 is raised} from the height χ to x ¹ , whereby the sinkers h ^{3 are} fixed, that is, prevented from getting their noses over the knives a ² during the subsequent further movement of the knife box.

It should also be noted that more than two knife-cases operate in the same way could become.

Fig. 2 is a Grundrifs of Fig. Ι and Fig. 3 is a schematic representation of the parts necessary to clarify the invention a double-lifting lace weave or. Bobbinet chair.

Claims (1)

Patent claim: Double lifting jacquard machine, characterized in that for the purpose of simultaneous Adjustment of several board sets by means of a set of cards respectively. All jacquards at the respective pattern formation through unused blanks of all knife boxes a card stop turned off and then the knife box to be lifted later appropriate sinkers used in pattern formation are raised a little, so that it is made impossible for the blanks that are inactive in the same pattern formation, to get to the knives of their associated knife box.
