Specification of Letters Patent.

Patented June 30, 1914.

Application filed July 31, 1912. Serial No. 712,576.

To all 'whom it may concern.

Be it known that we, PAUL SAeoNAmnn and E'rinNNn DEAUBONNE, citizens of the French Republic, residing at Paris, in France, have invented certain new and useful Improvements in the Manufacture of Carpets and Similar Fabrics, of which the following is a specification.

This invention relates to the prepa 'ation of pile warp or weft for the manufacture of carpets and similar fabrics, and it comprehends, briefly, certain hereinafter-described improvements in the process set forth in our prior Patent, No. 1,024,421, granted April as, i912.

rlhe patented process consists, primarily, in the production of a warp orrweft composed of a continuous band of Gingalette muslin, or the like, which is folded longitudinally and has secured between its sides a series of variously-colored pile threads, the latter being arranged longitudinally, one after another, in the order in which the corresponding colors appear in the pattern. Such process, however, when put into actual practice, has proved objectionable in some respects, notably in that the Gingalctte band, which constitutes the sole means for connecting the threads together, is comparatively expensive; must be cut, folded and wound; must be woven with the warp into the pile; can be removed, after weaving, only with the greatest difficulty, and with great danger' of injury to the fabric; and is entirely useless, and thus wasted, on being removed. On the other hand, with the present process, all of the afore-meutioned defects are overcome, or avoided, by forming the warp or weft merely by gluing together the adjoining ends of the pile threads, the adhesive being removable, after completion of the weaving, by simply dipping the woven fabric into a bath of water or other suitable liquid. A

In carrying o out the improved process, there may be utilized, for example, the apparatus represented in the accompanying drawing, whereof:

Figures l, 2 and 3 are part-sectional side elevations of the mechanism for applying the adhesive, showing the various positions assumed thereby; and Figa is a part-seetional side elevation showing a light modification of vthe invention and, also, certain parts omitted from Figs. l, 2 and.

As the spools, from which the short lengths or sections are taken, have the same arrangement and mounting as in our aboveidentified patent, and since the transfer of the selected spools into the apparatus and the application of the ends of the threads upon the conveyor are likewise effected in a substantially similar manner to that described therein, rcference may be had to said patent for a complete expose of such operations, and extended explanation and illustration in the present case are deemed unnecessary and,hence, are omitted. It is considered sufficient forpresentpurposes,therefore, to state that, as in the earlier process, the threads that go to make up the warp or weft are wenn d on long spools, the number of which is equal to the number of successive picks comprised :in the pattern, and that cach of such spools is itself constituted by a series of individual spools arranged side by side upona common spindle, the threads of theseindividual spools being of the same colors asthe parts of the pattern to which they respectively correspoml. Also, the threads are of sufficient length to enable the number of short lengths or sections requisite for the formation of the complete carpet to be taken therefrom. The long `spools. are brought in turn and in the proper order into operative position in the apparatus by means of suitable mechanism, and, on reaching such position, the ends of the threads that are wound on the component members of the long spool are deposited upon the above-mentioned conveyor and drawn through thc apparatus to be acted on by the glue-applying mechanism, as subsequently described.

In the construction illustrated in Figs. 1, 2 and 3, a portion of the convcyer is represented diagranmiatically in dotted lilies, and, as shown, comprises a series of pivotally-(anuuazted members f/ in the form et cross-hars, each of which is so grooved as to constitute, in effect, a separate table. The

number of such grooves is equal to that of the continuous warps or wefts to be produced, and the length of the conveyor itself, (which latter is of the endless type), is such that by the time that the warpsor wefts have been removed therefrom the glue or other adhesive binding the ends of the short threads together' will have ecmpletely solidified. The conveyor is given a .step-by-step movement by means of driving tem for moving the saine from one positionV to the other. rlhe tank has a hopper-shaped front portion which is provided with a series of discharge tubes 1 corresponding in number to the number of grooves in the conveyer members g, or, in other words, the

number of threads undergoing treatment, and the passage of the agglutinant through these tubes is regulated by means of a series of rods which project thereinto, the tubes and rods thus cooperating to form needle valves, as will be understood. valve rods proper are attached at their up* per ends to a cross-bar 3, controlled by a pair of retractile coil springs 4, the springs being` arranged at the ends of the hopper portion of the tank and exerting their tension upon bar 3 in such a way as to normally depress the valve rods and thus prevent discharge of the agglutinant from the outlet ends of the tubes 1. The latter are further provided with inlets 5, but said inlets, like the outlets, are normally closed owing to the depression of the valve rods. To maintain the agglutinant in a heated state, the tank may be equipped with a suitable heating coil 6. The tank is arranged for movement toward and from the conveyer, through the agency of the aforo-mentioned lever system, and at the beginning of the former movement, the valves are opened so as to permit a certain amount of agglutinant to pass through the inlets 3 into the discharge tubes 1 and to be subsequently de posited upon the rear ends of the previously formed pile-threads when the rod, 3 are depressed., iks represented in Figs. l to 3, the tank is provided upon its opposite sides with pairs of rollers T and 3, which run upon pins, studs or the like affixed to the tank walls. rl`he rear studs have also pivotally connected 'to them the front ends of a pair of links or bars 24, which are reciprocated by means of suitable mechanism, (not shown), and it is these bars, therefore, which serve to produce the working or forward and backward movement of the tank, the latter sinking duringits forward movement, and rising when moved backward. This effect is obtained through the coperation of the pairs of rollers T and S with fixed or sta`- tionary inciines or cams 9 and 10 mounted in the frame of the apparatus, the rollers traveling` down the inclines when the tank is advanced, and upward when it is retracted.

rlhe said i To open the valves, there is provided a pair of two-armed levers 11 pivoted on pins or studs 12 at opposite sides of the tank and having their front arms engaged with the bar 3, to raise the same against the tension of the springs 1, when said levers are rocked clockwise. The movement just specified is produced by the action of a pair of levers 13 that are disposed directly above the rear arms of the levers 11 and are furnished with terminal rollers that engage and depress said arms, as will be understood from Fig. l, such action being accomplished by the downward movement of a vertical rod 1G connected at its upper end to an arm 15 fastened to the rock shaft 1e1 which carries the said levers 13. Means is provided, also, for retaining or locking the valves in open position during` the forward movement of the tank. This locking is here shown as effected by moans of a pair of spring-actuated pawls 30 which are pivoted upon opposite sides of said tank and are drawn by the tension of their springs into engagement with a pair of studs 21 provided upon the adjacent levers 11, the arrangement being such that the engagement occurs after the clockwise rocking of said levers has been accomplished. At the end of the forward movement of the tank, the locking pawls are automatically released froln engagement with the studs, and the levers then return to initial position, the disengagement being effected b v a pair of arms 22 that are secured to shaft 14 and are designed to strike against a pair of studs 21 attached to said pawls. The levers 11 have finally associated therewith, a pair of spring-controlled auxiliary levers 33 which are pivoted at 33 to thel bars 21, and these levers 32 are so arranged as to be acted upon `at their upper or rear ends by the corresponding ends of the said levers 11, and as to engage at their front ends the tops of the cams or inclines 10, as shown in Figs. 2 and 3, in order to maintain the tank elevated and, also, in proper position with relation to a suitable device, (not shown), for cleaning the lower ends of the tubes 1.

As previously explained, the opening of the valves for the purpose of permitting the entry of the agglutinant into the tubes 1 takes place at the commencement of the forward movement of the tank. At the termi- `nation of this movement, the agglutinant is forced from said tubes, by the depression of the rods 2, upon the rear ends of the previously-formedv pile-threads, the levers 11 being released at that time to effect such depression, by theaction of the arms 23 which disengage the locking pawls L0 from the studs 21, whereupon the springs 4 are free Ato act. The tank is then retracted by the bars 34, and at the same time the spool from which the last set of sections was taken is returned tothe spool-carrier, a second spool brought into the apparatus, and the ends of the threads Wound upon its component or individual spools successively brought into alinement with the aforesaid last set of sections, straightened out, attached thereto, and finally severed. rthe mechanisms or devices for effecting these operations form no part of the present invention and may be either of the type shown in our prior' patent, or of any other desired cl'iaracter; hence, they are indicated merely diagrammatically in Fig. 4l, and will be given no extended description. It is Sullicient to state, therefore, that the ends of the fresh threads are first acted on by a rake 0, which straightens them out and forces them into proper position against the coated rear ends of the last set of sections or threads, that set, as will be understood, having been previously attached to the pile-threads already formed. Next, the said straightened ends of the fresh threads are acted upon by a compression mechanism le, which presses them against the coated ends of the last set of sections or threads, thereby effecting the connection of the two sets of threads together. At about the same time, the long spool from which the fresh threads have been taken is moved a slight distance bachr` ward, in order to unwind the length sullicient for the formation of the new sections. Next, a second compression mechanism m is brought into operation, and the first con1- pression mechanism c simultaneously detached from the threads and moved backward, this second compression mechanism serving to press the connected ends of the threads against the conveyor and thus attach the same thereto. The unwound portions of the fresh threads are then severed by the action of a knife n, after which the second compression mechanism m rises, the conveyor adifances, and the tank is moved forward, the agglutinant being deposited upon the free ends of the severed threads or sections at the termination of such forward movement, the above cycle of operations being repeated until the formation of the continuons pile threads completed. As the ends of these contirnious threads reach the end of the conveyer, they are removed therefrom, led between a pair offeed rollers s and sl, and wound upon a reel fr, the latter having associated with it a "ariahle-speed talte-up device, (not shown).

1While the conveyor, which carries the threads through the apparatus, may advantageously he of the endless chain type, such conveyer, by reason of the fact that it consists entirely of the pivotally-connected, grooved cross-bars, can be constructed only at a great expense. Accordingly, to cheapen the cost of the apparatus, a series of bands of mnslin or other suitable material may be substituted for the conveyorl previously re- :t'erred to, and a series of three cross-bars only used in connection with said bands. The short lengths or sections of thread are caused to adhere slightly to the bands during the formation of the continuous threads and to t avel therewith, and the said continuous threads can be readily removed from vthe bands prior to weaving so that the latter may be repeatedly used. lin Fig. Il, wherein this arrangement is illust-rated, 'r1 indicates the roller on which the bands 7' are wound side by side, t and r guide rollers for said bands, and y0, gl", and .(/wu the three crossbars over which the bands pass during the gluing operation. These bars are fixedly mounted in the f'ame c, and they are arranged for cooperation, respectively, with the knife or cutting mechanism fn., and the second and first compression mechanisms m and L', the bar gw() cooperating, also, with the lalie o, which latter rests thereupon at the end of its forward stroke. The operation is otherwise similar to that previously described. rlhe bands fr may also he used with the endless chain conveyor, if desired, as will be understood.
