WALTER W. HODGSON, OE PHILADELPHIA PENNSYLVANIA, ASSIGNOR OF TWO-THIRDS TO WILLIAM E. BEATTY AND FRED SUTCLIFFE, OF PHILA- DELPHIA, PENNSYLVANIA.
JACQUARD CARD-P'UNCHING MACHINE.
SPECIFICATION formingpart of Letters Patent No. 729,495, dated May 26, 1903.
' Application filed January 5, 1903. Serial No. 137,815. (No model.)
To aZZ whom it may concern:
Be it known that I,WALTER W. I-IoncsoN, a
citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Jacquard Card-Punching Machines, of which the following is a specification.
My invention relates to that class of card punching machines known as repeaters, the
:0 object of my invention being to so combine such a machine with a special construction of jacquard apparatus as to effect such apunching of the repeat-card that the latter will cause either the same shedding of the warps as or a different shedding of the warps from that caused by the corresponding portion of the primary card.
The figure in the accompanying drawing is a representation of sufficient of a card-punchzo ing machine with jacquard attachment to illustrate my invention.
In the drawing I have shown a series of grifE-bars 2, such as those which are ordinarily mounted in the reciprocating frameof a jacquard machine, and at 2 2 2, &c., are
shown a series of hooks, one for each griffbar, these hooks being connected, respectively, to the keys 3 3 3, &c., which control the operation of the punches 5, whereby the re- 0 peat-card is punched. The hooks are under control of a series of needles 4 4 4, 850., each connected to its corresponding hook. Each hook is normally in position to engage its griflf-bar, and if permitted to remain thus in engagement will when the griff-bar moves withdraw its key from behind the corresponding punch, so that the latter will be free to yield and will not punch the repeat-card, but if pushed out ofengagement with its griffbarthe hookwill'permit its key to remain in looking position and will cause the corre- I sponding punch to perforate the card.
Each hook-engaging needle is permitted to retain its normal position if that portion of the primary card corresponding therewith is punched and is pushed inward if the corresponding portion of the primary card is blank. Hence if the needles were connected up to the hooks in regular orderthat is to say, needle 4 to hook 2, needle 4 tohook 2", and so on the repeat-card would be the exact reverse of the primary card. I, however, wish to produce a repeat-card which is similar to the primary card on splits and the reverse of the same on pairsthat is to say, if in two adjoining rows of the primary card there is a perforation in one row and a blank in the other the repeat-card will be the same, but if both rows are punched orboth blank the repeat-card will be the reverse, whereby the warps will be shedded the same by each card for the insertion of the weft between them, but a pair of warps will be dropped by the repeat-card when lifted by the primary card, and vice versa. In order to attain this result, I connect pairs of needles to pairs ofhooks inreverse order. Thus needle 4 is connected to hook 2 needle 4 to hook 2, needle 4: to hook 2,needle 4 to hook 2, and so on. Hence a blank in one row of a pair in the primary card will result in punching the other row of the pair in the repeat-card, and a perforation in one row of a pair in the primary card will result in a blank in the other row of the pair in the repeat-card, while a pair of perforations in the primary card will produce a pair of blanks in the repeat-card and a pair of blanks in the primary card will produce a pair of perforations in the repeat-card.
Having thus described my invention, I claim and desire to secure by Letters Patent A jacquard card punching machine in which are combined a set of griif-bars, a set of hooks, punch-controlling keys connected to said hooks, and needles arranged in pairs, the needles of each pair being connected in a reverse order to a corresponding pair of hooks, substantially as specified.
In testimony whereof I have signed my name to this specification in the presence of 0 two subscribing witnesses.
WALTER W. HODGSON.
