LAPPET-LOOM.
SPECIFICATION forming part of Letters Patent No. 561,646, dated June 9, 1896.
Application filed April 4, 1895. Serial No. 544,404. (No model To LLZ whom t may concern:
Be it known that I, JOHN T. BOLTON, of Fall River, in thc county of Bristol and State of .llassacliuset-ts,have invented certain new and useful Improvements in Lappet-Looms; and l do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention consists of mechanism to he applied to looms weaving either plain or iigured goods for the purpose of putting an independent figure on the surface of the cloth.
It is fullydesoribed and illustrated in this specification andthe accompanying dra-win gs.
Figure l is a frontelevation of the lathe of a loom to which the improvement is attached, showing the extra yarn-beam and needle supporting and moving mechanism, also the treadles and cams that operate the mechanism. Fig. 2 shows a vertical section of the parts seen in Fig. l, taken on line sv a; in that ligure, looking to the left. Fig. 3 is a top view of the attached mechanism. Fig. shows the under side of the needle-plates that carry the auxiliary warp-figure yarns. Fig. 5 is a diagram of a piece of plain cloth with a figure made on its surface by the attached mechanism. Fig. 6 shows a side view of the mortised har L with the plates Il H' in section in the mortisc.
The character of the mechanism is such that it can he applied to looms for plain weaving using one shuttle only, or it ima5T he used on looms having a plurality of harness and shuttles. Its construction is as follows:
A is the lathe-beam of the loom; C C the swords or supports of the lathe.
D is an auxiliary yarn-beam to hold the yarn for the gures.
R R are supports extending up from the end frames of the loom to hold the yarnheam D.
B is the main cam-shaft.
F is an auxiliary cam-shaft.
.l is the reed.
S S are two vertical sliding hars or rods placed just inside the two swords O O, one at each side of the web, and holes are made vertically through the lathe-beam 'for the rods to slide in, while the lower ends of the rods slide in guides s s, attached to the inner sides of the swords C.
Extension hars or heads L L are attached to the upper ends of the rods S, and have at their upper ends holes made horizontally through them to receive a rod E, which is held fast hy set-screws in the heads of the hars L. Slots are mortised through the hars L Vj ust helow their heads to receive the plates H ll", that carr7 the needles o. The plates ll Il slide endwise in their slots in bars L, and the mechanism that moves them 4is held on an arm Y, secured to the end of the rod E by setscrews. It consists of a ratchet-wheel K, held on a sleeve loose on a stud a, fast on the outer end of the arm Y, and a cam T, fast on the same sleeve, with a lever F,held loose on the sleeve between the ratchet-wheel and cam. The lever F has a pawl b pivoted to its upper end that catches into the teeth of the ratchetwheel and turns it.
The connection between the ratchet-wheel and cam and the needle-plates H ll' consists of a knee-lever G, held on a stud c, fast in the arm Y. A curved rod d extends out from the upper branch of the knee-.lever G over the cam T, with its outer end resting on the cam, so that when the 'cam is turned it will raise and lower the end of the rod d and cause the lever Gr to move the front plate H by its lower end, which is pivoted to that plate at e. A plate s", Fig. 3, (omitted from Fig. l in order to show the cam T plainly,) is held on the stud CL outside the cam to keep the rod d in place on the cam. The front plate lvl. is connected to the back plate l-l' by a cord f, one end of which is made fast to the front plate, and then it is carried around a pulle7 71 held on a hulo attached to the rod E, and the other end of the cord f attached to the hack plate ll. (See Figs. and 4.) lVhen the plate H is drawn to the left hy a rise on the cam T, the cord f will draw the hack plate l-l to the right, and a closed spiral springj, which has one end made fast to harL and its other end fast to the plate H', will draw the two plates hack to place, when a hollow in the cam T allows the end of the .rod d to descend.
The lever F extends at an angle down past the lathe-beam A between two pins s' n, fast in the beam. Then the parts holding the ratchet-wheel and lever rise and fall, the pins cause the lever to move a short distance sidewise and tu rnthe ratchet-wheel by means of the pawl b. The rods S S and4 the parts attached to them have a vertically-reciprocating motion given to them by a cam N, fast on the auxiliary shaft F, (see Fig. 2,) though the cams N N may be held on the main camshaft B. The motion of the cam N is carried to the rods S by means of a treadle I, which is pivoted to the back girth B of the loom and has a bearing on the cam near its front end. A conneetingstrap c connects the front end of the treadle with a cross-bar P, fast at each end to the lower ends of the bars S. A crossbar V, having boxes fr o at each end fitted to slide on the rods S S, also receives a motion up and down from a cam N, fast on the shaft F', through a treadle I', held on a pivot attached to the back beam B', and a bar g con* nects its outer end with the cross-bar V. A series of needles r fr are inserted in the lower edges of the plates lI H. (See Fig. 4.) These needles fr have eyes at their lower ends through which is threaded the yarn e c, held on the yarn-beam. D. The vertical motion of the plates H 'Ill is limited to brin ging the lower ends of the needles yr down to the lathe-beam A, so that the shuttle t, Fig. 2, will pass over the yarn e and up, so that the said ends will hold the yarn e even or 'alittle above the upper shed of the warp ce, so that the shuttle will pass under it on its return.
The bar V has a series of guard-wires n' set on its upper side that stand at all times in holes made vertically through the lathe-beam A, and their length of motion up and down is about the same as that of the needles u just described. They rise after the lathe has beat up to serve as a guard to keep the shuttle from falling back vagainst the reed and getting out of place. lVhen the loom is in operation, the needles r, thro-ugh they motion derived as described from the cam N, its treadle I, and the connections, carry down the yarn @tand hold iti, so that the shuttle z5 passes over it; but before the next pick or return of the shuttle the needles u are raised with the yarn and the shuttle passes und er the yarn, and in that way it is bound down on the face of the goods.
To produce the figures on the goods, the bars H Il receive a motion sidewise, as fol lows: Every time the rod E, arm Y, and ratchet-wheel K descend the lever F, striking against the pin s', is thrown over to the right,
and the pawl l), on its upper end, moves to the left to catch a number of the ratchet-teeth. Then when the ratchet-wheel vand mechanism rise again the pin n pushes the lever F back to the left and the pawl l) pulls the ratchetwheel and cam T over a little to the right, causing the cam to raise the rod cl if it is on a rise on the cam, and the knee-lever G will draw the front needle-plate H with its needles to the left and the back plate H' to the right by the cord f; but if the end of the rod cl is on a decline on the cam T the motions of the plates ll H will be in the opposite directions, and whether the end of rod cl is on a rise or a decline or a circular portion of the cam, and the needles go to the right or to the left or remain in the same position, the yarn c' in them will be bound down to the face of the goods by the shuttle passing over them at each alternate pick, and the iigure formed by them will be iirmly attached to the goods.
It will readily'be seen that by varying the contour of the cam T endless forms ot ligures can be produced on the goods, and that the plates H ll' 'can be moved sidewise indepcndently 'of each other by having two cams side by side, or one at each end ol the rod E, with like devices `for moving them to those described. By putting the pins s and n more to the right to increase the angle of the lever F more motion can be given to the ratchetwheel'and its cam and-plates H H', or by putting the pins farther apart less motion oi' the plates will result.
Having thus described my improvements, I claim as my invention and desire to secure by Letters Patent In a surface-figlire-producing mechanism for looms, the combination with the lathebeam of the loom, of vertical sliding bars having bearings in the lathe-beam and on the swords below, a top bar connecting the upper ends of the vertical sliding bars, having mortises in their upper ends, plates sliding in said mortises, a spring connecting one of said plates to one of said vertical sliding bars, needles in the lower edges 'of said plates, a cord to connect said plates and passing about a pulley held on said top bar and said pulley, a ratchet-wheel and a cam fast to each other, and held on a pivot in an arm attached to said top bar, a linee-lever also held on a pivot in said arm and having a rod in one end resting on said cam, and its other end connected with one of the sliding plates, a lever held on the ratchet-wheel pivot and having a pawl on its upper end engaging in the ratchet-wheel, pins in the lathe-beam to move the lever and pawl, a cross-bar having pins in the upper side and `sliding on the vertical sliding bars with means for sliding said vertical bars, and said crossbar independently of each other, substantially as described.
