WILLIAM TALBOT AND WILLIAM HEPWORTH, OF PHILADELPHIA, PA.
JACQ'UARD MACHINE.
SPECIFICATION forming part of Letters Patent No. 236,278, dated January 4, 1881.
Application filed January 19, 1880.
To all whom it may concern Be it known that we, WILLIAM TALBOT and WILLIAM HEPWORTH, of Philadelphia, and State of Pennsylvania, have invented a new and 5 useful Improvement in Jacquard Machines, of
which the following is a specification.
Ourinvention relates to improvements in the well-known Jacquard machine for weaving figured fabrics, which improvemement adapts it for selecting the colored filling or weft-yarns used in weaving a web, which web isIout up into strips, and these strips are used as filling in weaving figured carpets, rugs, and other articles that are known as chenille fabrics.
Our said invention consists, first, in the combination of a trap-board of a Jacquard machine divided into sections, a series of cords, and filling fingers,'with two pattern mechanisms, one to control the sections and one to control the cords, and mechanism to operate the sections of the trap-board, as will be hereinafter described; second,in the combination and arrangement of mechanism whereby the movements of the card-cylinder are controlled by the cylinder or chain which controls the movements of the trap-board sections. We attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a front elevation of the machine. Fig. 2 is a top view of the same. Fig. 3 is vertical section taken on the line Y X of Fig. 2. Fig. 4 is a view of the connecting-rod and yoked lever for operating the card-cylinder. Figs. 5 and 6 are views of the trap-board sections. Fig. 7 is a view of a grooved cam for operating the mechanism that lifts the trapboard section.
Similar letters refer to similar parts throughneedles g g. One end of each of the needles 9 9 passes through the top of a lever, h, and on this end of the needle is out a screw-thread, and each needle is provided with two regulating-nuts. On the other end of each needle is placed a spiral spring.
On the top of the machine are mounted, to operate in bearings, two rock-shafts, D D. On these rock-shafts are arms E, E, E, and E. To these arms are attached lifting-rods ii. From the arms E and E" are connecting-rods F F, which connect to a crank, G, on shaft H, at the bottom of the machine. To the arm E is" a pusher, I, for moving the pattern-cylinder J.
K is a lever, which is connected tothe lever h by a connection, S. At the lower end of the lever K is a yoke,m. Through this yoke passes the connecting'hook L, one end of which is connected to a lever, (shown at the bottom of the machine,) which lever is operated by an eccentric-cam on shaft H, and through these devices the card-cylinder Bis moved for the change of one card for each complete revolution of the pattern-chain or'i'cylinder J, as will be hereinafter described.
PPP Parethe filling-fingers, to which fingers are fastened the knotted cords b b, (one cord from each section of the trap-board, as is shown in Fig. 3.) These filling-fingers are constructed asis shown and described in Patent No. 120,510, October 31, 1871, and-Patent N 0. 159,653, February 9, 1875.
In connection with our improvement we propose to use for inserting the filling hook or fillin g carriers asis shown and descri bedin Patent No. 13,352, August 7, 1855, and the above Patents N os.120,5l0 and 159,653. As thesedevices are old no description of them is needed here.
Previous to describing the operation of our improvement, it will be well to state that in thedrawings we show the trap-board divided into six sections, each section of the trap-board adapted for four cords, one lever, h, for each section, a pattern-cylinder with six divisions, a plain four-sided card-cylinder without cards, and four filling-fingers. When in practice we propose to divide the trap-board into fortyfour sections, and each section for ten cords, (but these numbers may be increased or diminished, as may be desired,) and for a trapboard of forty-four we shall want forty-four levers and a chain of forty-four divisions, and we prefer to use, in practice, the well-known roller-chain, now used in harness-motions on looms.
The operation of our improvement is as follows: Motion is communicated to the shaft H, which is so timed as to suit the filling-carriers ot' the loom. This shaft, through the connections F F, operates thelifting-rodsi i, and these in turn raise such hooks f f as may be selected by the pegs in the cylinder J, and the section of the trap-board connected to these hooks will be raised, and it in turn will raise such knotted cord as shall not have been pushed off the trap, and this cord will raise the fillingtinger to which it is connected. As the arm E descends, and just as the section of the trapboard is lowered, the pusher I will move the pattern-cylinderJ one division, and the peg in that division will select the hooks of another section of the trap-board, and so on, each section of the trap-board being raised in succession. WVhen the last division is to be raised the cylinder will present two pegs. One of these pegs will press in the lever h, which is connected to lever K by the connection S, and move said lever and the hook L to the left, which, as the hook is drawn down by the eccentric-cam on shaft H, will catch on the pin in one of the bellcrank levers which are connected to the slides that. carry the card-cylinderB and back board at the opposite end. The slides, cylinder, and back board will be moved to the left, and the cylinder B will be turned to the extent-of one card, and the back board will be pressed against the ends of the needles to a and press them all to the left. This will press all the knotted cords on the trap-board. As the cylinder B is moved back to the right by the weights on the bellcrank levers the card will push to the right all needles a a, except where a hole is punched in the card. By these means all the knotted cords but one of each section of the trap-board are pushed ott'. As each section of the trapboard is raised the knotted cord left on that section is raised, and with it the filling-finger to which it is connected. After each section of the trap-board has been raised the cardcylinder will be moved again and make such changes of the knotted cords as the design requires. It will be seen that one card does for all the divisions of the trap-board.
In weavingchenille, for some designs it may be desirous to keep up each division of the trap two or more picks. In such case we operate the lifters by a grooved cam, as shown in Fig. 7, which cam will be divided into such numberof parts, and constructed with a dwell for such number of picks as it may be desired to dwell for.
When dividing the trap-board into a large number of divisions, to save space we propose to construct them of metal and nest them, as shown in Fig. 6.
In working a division of the trap constructed for ten cords, and having ten filling-fingers, ten colors of yarn may be used; but if twenty filling-fingers be used and connected to each alternate section of the trap, and two sections of the trap be raised at one time, twenty colors may be used by arranging the cards so that only one section of the trap will raise a cord, all of which will be fully understood by those who are skilled in the art of weaving figuring chenille-filling, and arranging the designs on cards for Jacquard machines.
The controlling and operating the fillingfingers by a. Jacquard machine we do not claim, neither do we claim a Jacquard machine with two trap-boards, neitherdo we claim a Jacquard machine with two sets of cards, and which cards are worked alternately; but
As our improvement we claim- 1. Ina Jacquard machine, the combination of asectional trap-board, O G, cords b b, fillingfingers P P, two pattern mechanisms, J and B, and mechanism to operate the sections 0 O, substantially as shown and described.
The combination of card-cylinder B and pattern-cylinder J with the connecting mechanism for operating the card-cylinder B, one card for each complete revolution of the pattern chain or cylinder J, as shown and described, and for the purpose specified.
W. TALBOT. WM. HEPWORTH.
