JOHN osEPH DEVITT'IAND JOHN COROORAN, or YONKERS, NEW YORK.

LOOM F OR W'EAVING TUFTED FABRICS.

SPECIFICATION forming part of Letters Patent No. 367,094, dated July 26, 1887.

I Application filed April 24,1885. Serial No. 163,303. (No model.)

To all whom as rmty concern Be it known that we, JOHN J OsEPH Dnvrrr and JOHN COROORAN, both of Yonkers, in the county of Westchester and State of New York, have invented a new and Improved Loon for Weaving Tufted Fabrics, of which the following is a clear, full, and exact description.

This invention relates to needlelooms de yarns down through the warp, the knives that cut the tufts, and the comb that lifts the tuftyarns up through the warp.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all .the figures.

Figure 1 is a sectional plan view of our new loom,taken on the line as 00, 'Fig. 2, parts being broken away toshow the construction of other parts of the loom. Fig. 2 is a side elevation of the loom. Fig. 3 is asectional elevation of the loom, taken on the line 3/ y of Fig. 1, parts being broken away to avoid confusion. Fig. 4 is a sectional elevation taken on the line 2 2' Figs. 5, 6, 7, and 8 are detailed views of themeans for'operating the tuft-cutting knives. Fig. 9 is a transverse sectional elevation of the knives and their supporting plates, showing'also one of the spring-retain- Figs. 10, 11, 12, and 13 illustrate, respectively, in enlarged views and in connection with sections of carpet, the sequence of movements of the nippers, the lay, the comb, and the knives, Figs. 10 and 11 showing in sectional elevation tuft-yarn spools and their frames and a portion of the transferarms. Fig. 14 shows a section of the fabric and the knives ready to cut the tuft-yarn, and Fig. 15 shows an enlarged section of a part of the tufted fabric or carpet made by the loom. Fig. 16 is a side "iew ofthe cam E, that moves the shuttle. v

A represents the main frame of the loom,

which may be of any appropriate form and size to receive the powershaft B and other working parts.

Upon the bracket A of the main frame A is formed or secured the shuttle-race B, and

upon the arm A, on the opposite side of the frame A, is placed the sliding block 0, to which is attached the needleD,which is reciprocated threads a one selvage of the carpet or fabric Y being woven.

The shuttlerace B is, by preference, curved,

as shown in Fig. 1, and it is channeled or I grooved in its upper surface, as shown at (1, Figs. 1 and 4, to form the flanges d to receive the T-rib d", formed upon the under surface of the shuttle-carrier E, which rib holds the carrier in place. A plate, E", is secured to the inner edge of the race B, against which the shuttle E runs, and this plate E has the openinge, Fig. 4:, made through it for the passage of the point of the needle D, and this plate E has also the guard f secured to it to prevent the looping or 'tangling of the shuttle or selva-ge thread 0, where it reaches from the completed portion of the fabric to the shuttle.

Theshuttle-carrier E has thestuds 99 formed upon its'upper surface, and the carrier and the shuttle E are reciprocated upon the race B, so as to produce a reciprocating action, in which there is a dwell while the needle is withdrawing past the shuttle by the vertical shaft E and the forked arm or plate 13*, secured to its upper end, the shaft E being rotary reciprocated by the cam E on shaft 13, and the spring E, (shown clearly in Fig. 1,) the said cam E acting to turn the shaft'E by the lever F and connecting-rod F,that connects the lever F with the horizontal arm F, attached to the shaft E The arms or prongs e e of the divided plate E* embrace the pins 9 g of the shuttle-carrier E, and also the ends of the shuttle E, and as the shaft E and plate E are rotary reciprocated the prongs e. e cause the 4 shuttle and shuttle carrier to traverse the curved shuttle-race B, and the prongs c e are such distance apart relative to the length of the shuttle and the distance the pins 9 y are apart as to leave space for a slight movement of the shuttle-carrier independent of the plate E, so that the "shuttle will not out or break the weft-thread a in passing through the loop or fold thereof formed by being carried across the loom by the needle I). The needle D is reciprocated by the cam G on shaft 13 acting through the lever G,bell crank lever G and the conneeting'links G and G, which respectively connect the lever G with lever G and the latter lever with the block 0, as shown clearly in Fig. 4. The lever G is held in contact with the cam G by the heavy coiled spring (Shown in Fig. 2.) The needle Dis formed with the hooks or prongs h, and made spoon- Shaped at itsinner end, as shown clearly in Fig. 1, so that as it carries the weftthread forward through the opening 6 in the plate E in front of the shuttle E, the back of the needle will not interfere with the shuttle in picking up theloop or fold of the wcft'thread, which the nose or point of the shuttle will hold while the needle D recedes. Then the shuttle will be carried on by the action of the cam through the loop or fold and back to the rear of the race B, ready again to take up and pass through the next shotof weft-thread forced forward by the needle D. The weft-thread It comes from the spool H, placed at the needle side of the loom, and passes from the spool H first up between the tension wheelst 17', then through the eyes i i i", and is fed to the needle D that is, laid across the hooks h thereof from the front by the feeder J, which is pivoted at j and formed with the prongs or arms jj, that straddle the weft-thread a, and is reciprocated by the action of a cam, J, on the shaft B and the spring J, that act through the lever J and connecting-rod J. (Shown clearly in Fig. 2.) The feeder straddles the weft-thread a at a point slightly in front of the point of the needle when the same is withdrawn lo the limit of its outward movement, as shown clearly in Fig. 1. The tension-wheel is held in stationary bearings, while the wheel i is journaled at the lower end of the arm L, which is properly reciprocated for grasping and releasing the weft-thread by the cam K on the shaft B and the spring K, the cam and spring acting through the lever K and the connecting-rod K, that connects the lever K with the arm k, as shown in Fig. 2. Any slack that may occur in the weft-thread a will be taken up by the grooved roller 7.1, which is of c011- sidcrablc weight and rests against the weftthread, as shown in Figs. 1 and 2, the spring c being provided to prevent the roller k and pivoted arm 7;, on which it is mounted, from dropping out ofplace when theloom is not in operation.

In weaving tufted fabrics the yarn Z, (see sheet 3 of the drawings,) from which the tufts are formed,will be carried on spoolslflattached to spool-framesl, carried upon endless chains L, that pass around the chain-shat t L, the same as in Letters Patent No. 233,290, dated Octo' ber 12, 1880, and the spool-frames will be carried from the chain L down near to the warpthreads I) by transfer-arms M, the same as in said patent.

For drawing the tuft-yarns Z from the spools Z" down through the warp threads to be wrapped around the weft or filling and bound in or upon the fabric, we employ a series of nippers, N, (shown in Figs. 3, 10, and 11,) arranged so that a pair of nippcrs will stand be tween each pair of warp-threads. The nippers are composed of the jaws m and a. The jaws m are attached to the bar 0, while the jaws a are attached to the bar 0, that is secured to the bar 0 by the pins or bolts 0, that pass through the slots 0 in the bar 0, the ,slots permitting the bar 0' to have a slight longitudinal movement for opening and closing the jaws, this movement being imparted by the cam O on the shaft B (see Fig. 1) acting through the lever 0", attached to the bar 0, and pivoted or fulcrumed on the stud or pin 0' formed upon the bar 0, as shown in Fig. 3. The bar 0 is attached by the arms 0 and o to the shaft 1), the arm (f'being pivoted to the arm 0, which is rigidly secured to the said shaft p. The bar 0 is also attached by the connecting-rod p to the arm 11* of the sleeve p, that is placed loosely upon the shaft 1?. The shaft 2 has the downwardly-projecting arm attached to it, and the slecvep has the downwardlyprojccting arm attachedto it, so that the said shaft 1) and sleeve 1) may be rotary reciprocated by the cams PPKshown in Fig. 1) 011 shaft B, acting through the levers p 1) and connectingrodspand p. This movement of the shaft 1) and sleeve 1) serves to raise the nippcrs to the position shown in Figs. 3 and 10, where they are closed to grasp the tuft-yarns and to lower and advance them to the position shown in Fig. 1.1, where they stand out of the way of the lay Q and reed (Shown clearly in Fig. 3.) Before reaching the position shown in Fig. 11, the nippcrs, after drawing the tuft-yarns below the warp, are opened by the action of the cam O and lever O to release the tuft-yarns Z, leaving the ends thereof between and reaching below the warpthreads, as shown in Figs. 11. and 12. The tuft-yarns being thus drawn down through the warp and released by the nippcrs, the needle D puts in a shot, I), of weft or filling, which of course stands in front of the tuft-yarns I, as shown in Figs. 11 and 12, and then the weft is beaten up by the lay Q, which is operated by the cam Q on shaft B, acting through lever Q, connecting-rod Q, and arm Q of the lay, the same being secured upon the shaft Q', as shown clearly in Fig. 3. The beating having been performed, the comb R, the teeth 9 of which are upturned, as shown clearly in Fig. 12, is operated by mechanism,hereinafter described,

soas to comb up or raise the lower ends of the tuft-yarns Z around the shot b--that is, raise them from the positionshown in Figs. 11 and 12 to that shown in Figs. 13 and 14. This done, and while the comb R still holds the yarns Z, the needle D inserts the shot of filling 12 which is beaten up and bound by the warp,

and then the knives S S are brought forward from the position shown in Figs. 1, 2, and 3 to that shown in Fig. 14.

The knives S S have ashear-cut, each being formed with corresponding. cutting-fingers, s 8, (shown clearly in Figs. 5 and 9,) the sharp edges of which are moved across each other at the proper time by' a longitudinal movement of the knives S S. The knives S S are held upon the horizontal erossplate T, attached to the arms T T, rigidly secured to the abovementioned shaft 1?, held in the frame of the loom between the center screws, t. The knives are kept in position upon the plate T by the bolts or studs t t, that pass through slots in the knives, so that the knives may be moved longitudinally in opposite directions.

The lower knife, S, has the eye-stud t secured to it, which reaches up through the slot t in the upper knife, S, and this upper knife has the eye'stud' t secured to it, and to these eyestuds t t are attached the ends of the coiled spring U, that normally holds the knives in such position that the cutting-fingers of the upper knife stand immediately over the cutting-fingers of the lower knife, as shown in Fig. 5, so thatwhen the knives are carried rearward for cutting the tufts the tuftyarns" will come properly between the cutting-fingers.

The knives are carried rearward to cutting position by the action of the cam V on shaft B acting through the lever V, (shown clearly in Figsfi and 7,) the connecting-rod V and arm V the latter being rigidly secured to the shaft 1?, as shown clearly in Fig. 6. Theknives are brought back to vertical position by the springV. (Showhin Fig. 6.) The knives having been carried down to the tuft-yarns in cutting position, they are moved longitudinally to cause the cutting-fingers s to effect the cutting of the yarns by the cam W acting through the levers W WV and chains WV W that connect the knives S S, respectively, with the outer ends of the levers W W, as shown in Fig. 5. The said chains pass over the pulleys w to. so that when the adjacent ends of the levers W W are elevated by the toe on the cam WV the corresponding depression of the outer ends of the leverwill draw downward upon the chains,and thus simultaneouslymove the knives longitudinally in opposite directions'. The toe of the cam W having passed the levers XV W, the spring U will act to return the knives, and also the chains and the levers W, to their original positions. The cam W is secured upon the shaft W which is revolved from the main shaft B by the beveled gear-wheels W (Shown clearly in Figs. 1 and 8.)

The comb R is pivoted at its ends to the bars R R, that are held in the race-pieces R R and are reciprocated longitudinally from the cams R' R on shaft B by the bent levers R (see Fig. 3) and springs R that draw the levers It backward, as illustrated in the lastmentioned figure. The comb R while being movedforward is tilted by the cams It acting through the levers R and connecting-rods R so that the teeth of the comb pass down through the warp threads b just in the rear of the tuft-yarns Z. Then, by the action of the cams R, levers R and rods R the comb is tilted back to bring the upturned ends of the teeth q in front of and in line with the yarns l, as shown in Fig. 12. Then the springs R in connection with cams R and levers and rods R R, act to gradually draw backward the comb R, the teeth of which are at the same time tilted upward by the cams R and levers R and rods R which movements continue until the comb reaches the position shown in Fig. 13, where it completes the work of combing the yarns Z around the shot b of weft or filling, which is inserted by the needle D,as above described. At the position shown in Fig. 13 the comb R dwells while the slot 12 of filling is inserted by the needle D, after which it is carried back to its original position-that shown clearly in Figs. 1 ,and 3ready to repeat the operation for each row of tufts that is put in the fabric.

In Fig. 2 L represents the selvage-point,-

which is pivoted above the warp b, and is reciprocated by acam, L on the shaft B,through the lever l and connecting-rods Z, (shown in Figs. 1 and 2,) so that it drops over each slot of weft or filling thread a just after each stroke of the lay Q, to hold the filling at the selvage while the next shot is being inserted by the needle D, thus making a close weave at the edge of the fabric,as will be understood clearly from Fig. 2.
