SPECIFICATION forming part of Letters Patent No. 361,408, dated April 19, 1887.

Application filed Mitre-I110, 1886. Serial No. 104,679.

To all whom it may concern:

Be it known that l, WILLIAM V. GEE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvementsin Machines for Lacing or Stitching Together Pattern-Cards for Jacquard Looms; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it app'ertains t make and use the same My invention relates to machines for lacing or stitching together pattern-cardsfor Jacquard looms and the improvement consists in the construction and arrangement of the several parts of the machine, as will be hereinafter described, and more particularly pointed out in the claims.

A A represent two of the pattern-cards sewed together.

y y y are the lacing-holes.

y y y are the three rows of stitching as they appear on the top of the cards.

8 is a card-support extending over the top of the machine and under the cards as they pass along.

The loose cards, having therein the proper amount of lacingholes on either side thereof, as shown in Fig. 2, being placed in the rackA, one above the other, and the top and bottom needles being threaded, the operation of the machine is as follows, viz: The driving-wheel being turned, the sliding carriage- D is pulled forward by means of the cam (0, operating the lever a Thismovement of the carriage causes the pawls or catches d d to engage with the notches on the inside of the chains 13 B, thus carrying said chains along on the tracks 1 F. The spurs or projections :10 w on the upper surface of each section of the endless chains will each time as they pass along pull out the bottom card from the rack A, and this will be repeated at every forward movement of the carriage D. Vhen the cards have been brought forward to the needles, the operation of sewing is commenced, to do which the bottom needlebar, with its accompanying needles, each having a thread therein, is first forced or carried upward by the cams m", operating on the jointed levers m". This movement will bring the bottom or vertical needles up through the laeing-holes in the cards until the eye of each needle, with its attached thread, is some distance beyond the line of the upper or horizontal needles. The bottom needles being in this position,thetop needle-bar, f, carrying the top or horizontal needles, f, is given a forward horizontal movement by the operation of the cams 0'0 upon the jointed leversf. This carries the needles f with their attached threads, between the bottom needles and their attached threads at a point just below the eyes in the bottom needles, thus forming loops' of the bottom threads over the said top needles and their threads. bottom needles down out of the holes in the cards, leaving the bottom threads still looped over the top or horizontal needles and corresponding threads. The cards now move forward the distance between the lacing-holes, and, as the top needles remain stationary dun ing this forward movement of the cards, the loops of the bottom threads previously formed on said top needles are pulled along on the needles the same distance that the cards are moved. The forward movement of the cards brings the next adjacent lacing-hole immediately over the bottom needles. Being in this position, the top needles are carried forward until the eyes therein project a short distance beyond the lacing-holes immediately over the bottom needles. The bottom needles, with their attached threads, are then moved upward, passing between the top needles and their corresponding threads, thus forming a loop of the top threads around the bottom needles and their attached threads. After this the top needles are again drawn back until the loop of the bottom threads, previously formed on said top needles, is dropped off,

when it will be'drawn down into the lacinghole immediately underneath. The top needle-bar is now moved forward. This movement will carry the needles, with their attached threads, between the projecting bottom needles and their attached threads. The bottom needles are then withdrawn, leaving the bottom threads looped over the top needles and their accompanying threads. The cards being again moved forward one lacing-space by the forward movement of the sliding carriage, the loops of the bottom threads slide along the top or horizontal needles, and the upper needle-bar again advances, so that the eyes of the upper needles will be a little beyond the next adjacent lacing-holes and ready for the next upward movement of the bottom needles, and so on indefinitely.

At every upward movementof the bottom needles the lever r, operated by the cam r on the shaft 0, will cause the fingers p to close the pivoted jaws 19 upon the tension-plates p, thus holding the bottom threads tightly and allowing no more to unwind from the spools; consequently these bottom threads will be tightened, thus pulling the stitch previously formed down into the lacing-holes in the cards. When the bottom threads are thus drawn tight for the purpose of pulling the stitches down in the lacing-holes, the books 9 g on the bar g, resting upon the top of the cards, protect them from the force of the pull and prevent the thread from tearing through.- By having these hooks in the position shown, a

.thin or very ordinary grade of card may be used and the stitch drawn as tightly down as when using a good or superior quality of cards. The closed end of the slots in the hooks 0 0 0 The continued motion brings the The needles f and 7c are preferably made with a semicircular out just back of the eyes therein, as shown in Figs. 1". Through this cut-away part of the needles and inside of their accompanying threads the opposite needles and their attached threads are projected.
