JACQUARD MECHANISM.

To all whom t may concern:

Be it known that I, MAX Knrssrnr, a citizen of the German Republic, residing at Wyomissing, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in .Iacquard Mechanism, of which the following is a specification.

My invention relates to jacquard mechanism, and particularly to means for positively freeing the used acquard cards from the card prism as fully set forth in connection with the accompanying drawing and specifically defined in the subjoined l5 claims.

Fig. 1 is a longitudinal elevation of a j acquard prism and carrier arrangement embodying my invention.

Fig. 2 is a. cross-sectional view on the line 2-2 of Fig. 1, indicating also the usual sinker wires which cooperate with the apertured cards.

Fig. 3 is an enlarged cross-sectional view on the line 3w3 of Fig. 1.

Each of the jacquard cards 5, connected by lacings 6 to form an endless belt, is provided as usual with pattern perforations to permit the passing of determined sinker wires S for properly' setting corresponding hooked lifter wires not shown; and is also provided as indicated with guide apertures adapted to engage the guide projections 11 on the rotary prism or card drum as shown in Janssen Patent No. 1,339,957 issued May 11, 1920. The prismatic drum 16 is provided with registering` perforations Il for the wires 8, with circular series of the guide projections 11 for engaging the several cards thereon, with a series of circular lacings, and with a ratchet wheel or wheels 15 through which periodic turning movement is imparted, as usual.

The prismatic card drum 1G is mounted,

.45 as shown, in the upper ends of a pair of carrier arms 20, 20, pivoted to the machine frame at 21 and suitably operated to swing the card prism toward and away from the wires 8 with a turning movement thereof adapted to present a new card to the wires at each forward swing.

grooves 17 alined as indicated with the cardv Application led April 14, 1923. Serial No. 632,154.

As the card prism 16 is partially turned to present new cards, it is important that the used cards should be freed therefrom so as to promptly fall away from it instead of being carried around with it so as to cause trouble as is ordinarily apt to occur. To this end I provide relatively fixed stripper fingers 25, 25, 25, arranged in the path of the used cards with their free ends bearing upon the periphery of the prism, so as to positively disengage the lowering cards, as clearly indicated in Fig. 3. As shown these fingers are fixed to a parallel bar 26 of the prism carrier arms 20, 20 65 so as to be swung therewith, and have their free ends engaged in the prism grooves 17 so that the used cards will contact therewith in falling from the prism and be positively freed from the prism.

The preferred arrangement of these fingers which is set forth may obviously be readily modified so long as they are maintained in the path of the used cards so as to positively clear them from the prismatic 76 drum as set forth.

Vhat I claim is:

1. In a jacquard mechanism, the combination with an oscillating prism carrier and an intermittently rotated card prism having 80 circular series of projecting card-guide pins adapted to engage guide apertures in the cards; of a cardstripper finger secured to` said oscillating prism carrier rbelow the rotated prism and having a free end adapted S5 to constantly bear against the periphery of the latter soas to free the used cards therefrom.

2. In a jacquard mechanism, the combination with an oscillating prism-carrier, and a circularly grooved and intermittently rotated card prism having circular series of projecting card-guide pins adapted to engage guide apertures in the cards; o-f a card-stripper finger secured to said oscillating prism carrier in the path of the used .cards and having a free end loosely engaged in a circular groove of the prism.

In testimony whereof I afiix my signature.

MAX KRISSIEP.
