lViACl-HNE FOR LINKING WARPS.

SPECIFICATION forming part of Letters Patent No. 387,165, dated July 31, 18881.

Application filed December 22, 1887. Serial No. 258,668. (No model.) Patented in England October 24, 1883, No. 5,059.

.To all whom it may concern.-

Be it known that I, VILLIAM HURST, of Rochdale, in the county of Lancaster, England, (COlJtOH'SPlDI'lGIQ) have invented a new and use ful Improvement in Machines for Linking WVarps, (for which I have obtained Letters Patent of the United Kingdom of Great Britain and Ireland, No. 5,059, dated October 241383,) of which the following is a specification.

My invention relates to machinery or apparatus for forming what are commonly called chained or linkedHvarps. By means ofmy lnvention I am enabled to chain or link warps more quickly and with greater certainty and regularity than heretofore, and by my invention the yarn being linked or chained is sub jected to less strain and injury than it has hitherto been while being chained or linked by machines hitherto in use.

My invention consists in the mechanism hereinafter described and claimed for effecting the chaining and linking operations.

In the accompanying drawings, Figure 1 is a side elevation of a machine constructed according to my invention. Fig. 2 is asectional plan of the same; Fig. 3, a partial front view; Fig. 4, a plan upon a larger scale; and Fig. 5 a front view, also upon a larger scale. Figs. 6, 7, 8, and 9 are views showing portions detached, and Figs. 10, 11, 12, 13, 14, 15, and 16 illustrate the formation of the chains or links. Fig. 17 is a front view, and Fig. 18 a side view representing a modified mechanism for actuating the trumpet through which the warp to be chained or linked is passed. Fig. 19 is a diagram representing an apparatus by means of which the threads forming the chained or linked warp are drawn direct from the bobbins.

The same letters of reference are applied to corresponding parts throughout the whole serles of figures.

In the accompanying drawings, a (0* are end frames connected at the top by a cross-frame or cross-beam, b. Extending between the end frames, a (5, and secured thereto, is a crossframe or cross-beam, 0.

(Z is a shaft supported in bearings, secured to the end frames, a a respectively. Upon the shaft (Z are a fast pulley, e, and a loose pulley, f. The shaft (Z is provided with collars, by which such shaft (Z is prevented from moving longitudinally. Fast upon one end of the shaft d is a bevelwvheel, g, gearing into a bevel-whee], h, fast upon a vertical shaft, j. The vertical shaftj is supported in bearings 70. Fast upon the lower end of the vertical shaft 3' is a plate, Z, to which is secured a crank-pin,

on. The shaftj is prevented from movinglongitudinally by means of the boss of the bevelwheel h and the boss of the plate Z. Fast upon the shaft d are bevel-wheels an The bevelwheel a gears into a bevel-wheel, 0, fast upon a vertical shaft, 19, carried by a bracket secured to the cross-frame or cross beam 0.

Fast upon the lower end of the shaft 1) is a plate, q, provided with a crank-pin, r. The shaft p is prevented from moving longitudinally by means of the boss of the wheel 0 and the boss of the plate q. The bevel-wheel a" gears into a bevel-wheel, 0*, fast upon a vertical shaft, 11*, carried by a bracket secured to the cross-frame or cross-bcan1 0.

Fast upon the shaft 19* is a plate, q provided with acrank-pin, 0*. The shaft p is prevented from moving longitudinally by the bosses of the wheel 0* and of the plate Projecting from the cross-frame or crossbeam c is a bracket, 8, supporting a vertical shaft, t. Fast upon the upper end of the shaft 15 is an arm, n, to which is j ointed an arm, 2;, provided with a trumpet, w. The arm n. is formed with a slot, n, in which the arm n is capable of being moved vertically upward and downward. Upon the lower end of the shaft 75, and fast therewith, is an arm, 00, provided with a pin, 00, embraced by one end of a connecting-rod, y, the other end of which embraces the crankpin m, carried by the plate Z.

Secured upon the shaft d is a cam, z, which, as the shaft (Z rotates, causes the arm :1; to be raised and lowered while the said arm v is being moved lengthwise of the cam e, as will be hereinafter more particularly described.

As some of the parts to be hereinafter described are repeated upon both sides of the machine, I shall describe such of the said parts as are situate at one side of the machine and affix to corresponding parts situate at the other side of the machine the same letters of reference,with the addition of an asterisk, thus Secured to the cross-frame or crossbeam c is a bracket, Z, (shown more clearly in the detached views,Figs. 6, 7, 8, and 9,) Fig. 6 being a side view; Fig. 7, a side view, partly in section; Fig. 8, a crosssection taken on the line A B of Fig. 7, and Fig. 9 a view showing a portion detached. The bracket Z is provided with a recess, 2, formed therein, and along a portion of the upper edge thereof are formed ledges which support a bar, 3, capable of being slid longitudinally upon the said ledges. The end of the bar 3 is extended, as indicated by the dotted lines in Fig. 2, and curved sidewise at its extremity, so as to form a hook, 4, such bar 3,with its hook 4,being more clearly shown in the detached View, Fig. 9. 5 is a plate secured to the cross-frame or cross-beam c by screws, a projecting part of which plate 5 is curved at its extremity, so as to form a hook, 6, and an extended part of a bracket, 7, is also curved sidewise at its extremity, so as to form a hook, 8. The end of the hook 6 is curved downward, and the end of the hook S is curved upward, the said two ends being in contact and forming a hollow hook, 9, which, for convenience, I will hereinafter refer to as the book 9. Within such hollow hook 9 the extended end of the bar 3 is capable of being slid backward and forward, as will be hereinafter pointed out. To a part of the bar 3 is attached one end of a spring, 10, the other end of which is secured to a projecting part of the cross-frame or cross-beam 0. The spring 10 tends constantly to draw the bar 3 in the direction indicated by the arrow 0. Secured to the bar 3 is a bracket, 11, part of which is situate within the path of a revolving cam, 12, so as to be capable of being moved thereby in a direction opposite to that indicated by the arrow 0, the movement of the bar 3in the directiou indicated by the arrow 0 being limited by a stop, 13, on the bar 3, and a stop, 14, secured to the cross-frame or cross'beam c. The cam 12 is mounted fast upon the shaft d,

Secured to the end frame, a, is a bracket, 15, to which a stud, 16, is secured. Mounted upon the stud 16, so as to be capable of being rotated thereon, is a wheel, 17, the teeth of which gear into the teeth of a rack, 18, provided with projecting parts, which are embraced by a bracket, 19, secured to the bracket 15, in which bracket 19 the rack 18 is capable of being slid longitudinally while its teeth are in gear with those of the wheel 17. The teeth of the wheel 17 and the teeth of the rack 18 are indicated by dotted lines. To one end of the rack 18 a connecting-rod, 20, is connected by means of a pin, 21, the other end of the connecting-rod 2O embracing the crank-pin r, secured to the plate q. Fast with the wheel 17 is an arm, 22, provided with a curved part, which constitutes a hook, 23. Upon rotary motion being imparted to the pulley e, so that such pulley e rotates in the direction indicated by the arrow D, the plate Z and crank-pin at will be rotated in the direction indicated by the arrow E. The rotation of the crank-pin at will, by means of the connecting-rod y, pin an, arm :0, shaft t, arm a, and arm '0, cause the .and then in the other.

trumpet w to be oscillated sidewise. The cam 2 being rotated in the direction indicated by the arrow D, the rotation of such cam 2 will cause the arm '0 and trumpet w to be raised and lowered twice during each revolution of the cam z. The rotation of the plate Z will cause the trumpet w to be oscillated sidewise to the points F and alternately, and while the trumpet w is being so oscillated the cam 2 will cause such trumpet w to be carried along the line G (1* in the direction indicated by the arrows H, the said trumpet w first passing below and around the hook 9 and then be low and around the hook 9*. Upon rotary motion being imparted to the plate (1, so that such plate q is rotated in the direction indicated by the arrow K, the rack 18 will, by means of the connecting-rod 20, be caused to traverse longitudinally first in one direction The traversing of the rack 18 will, by means of the wheel 17, cause the hook 23 to be turned first in one direction and then in the other, the said hook 23 at certain times passing between the hook 6 and bracket 7 and beneath the hook 4. To feed the warp to be chained or linked to the chaining or linking machine at such rate that little or no tension is produced upon the warp while such warp is being chained or linked, I employ the apparatus to be next described.

24 24* are end frames, to which are respectively secured brackets 25 25*, supporting a shaft, 26, fast upon which is mounted a drum or roller, 27. The shaft 26 is prevented from moving longitudinally by collars formed thereon or seen red thereto. Resting upon the drum or roller 27 is a roller, 28, having an axle, 29, which axle 29 is supported by brackets 30 30*, in which it may be rotated. The brackets 30 30* are respectively secured to levers 31 31*, one end of each of which turns upon a bar, 32. the ends of which pass into openings formed through the end frames, 24 24*. Depending from the ends of the levers 31 31* are weights 33 33*, respectively, such weights 33 pressing the roller 28 into contact with the roller or drum 27.

34 is a shaft, one end of which shaft 34 revolves in a bracket secured to the end frame, 24*, while the other end of such shaft 34 is capable of being rotated in a bracket carried by a lever, 35. The lever 35 is capable of being turned at one end upon a stud secured to the end frame, 24. The shaft 34 is prevented from moving longitudinally by means of collars.

36 is a shaft passing through and capable of being revolved in holes formed through the end frames, 24 24*. Upon the shaft 36 is secured a' cam, 37, which is situate beneath the lever 35. Fast upon the shaft 36 is an arm, 38, provided with a stud which passes into a hole formed through the end of a rod, 39, by means of which the machine may be started or stopped. Fast upon the shaft 34 is a pulley, 40, around which passes an endless belt, 41, which communicates rotary motion to the pulley 40 from any convenient source of power.

Fast upon the shaft 34 is a pulley, 42, the circumference of which is preferably covered with leather. The pulley 42 is shown as being in contact with a pulley, 43, fast upon the shaft 26. Fast upon the shaft 26 is a pulley, 44, around which and around the pulley 6 passes an endless crossed belt, 45, such belt 45 transmitting motion from the pulley 44 to the pulley e and shaft (1. Secured to the bar 32 is an eye, 46.

Having thus described the various parts of the machine, I will proceed to show in what manner they operate when forming a warp into a chain or links.

The warp L to be chained or linked is passed through the eye 46 and between the drum or roller 27 and roller 28, after which such warp L is passed through the trumpet w and around one of the hooks 9 9*. During this time the rod 39 has been raised, so as to allow the pulley 42 to pass out of contact with the pulley 43. Upon the rod 39 being lowere-d the pulley 42 will be pressed against the pulley 43 and the drum or roller 27 and roller 28 will draw forward the warp L and deliver it to the trumpet w. Icause the drum or roller 27 and roller 28 to rotate at such circumferential speed that the warp L is delivered to the chaining or linking apparatus at such speed that little or no tension is produced in the warp Lwhile such warpL is being chained or linked. The diagrams, Figs. 10 to 16, inclusive, show the manner in which the parts hereinbefore described operate in order to form the warp L into a chain.

In Fig. 10 the trumpet'w has passed'beneath and around the hook 9*, leaving the warp L passed around such hook 9*, and by a continued movement has passed beneath and around the hook 9, and again beneath and around the hook 9*, until it arrives in the position in which it is indicated in Fig. 10. The hook 23*, turning in the direction indicated by the arrow M*, as will be hereinafter de scribed, brings forward a loop, N*, of warp previously passed around the hook 9*. A continued movement of the hook 23* in the direction indicated by the arrow M* will carry the loop N* of warp clear of the hook 9* and allow the said loop N* of warp to pass upon the loop 0* of warp, which is around the book 9*, as shown in Fig. 12. The sliding hook 4* is then drawn in the direction indicated by the arrow 1 by the rotation of the cam 12*, and draws along with it the loop 0* of warp until it arrives in the position in which it is indicated in Fig. 13, and while the sliding hook 4* isin such position the revolving hook 23* passes in the direction indicated by the arrow Q*, beneath the hook 4*, and through the hook 9*, after which the hook 23* is rotated in the direction indicated by the arrow M*, after which the sliding hook 4* will be liberated by the rotation of the cam 12* and be drawn by the spring 10* into the position in which it is indicated in Fig. 14. A loop, R*, of warp is then passed around the hook 9* by the trumpet w, and a repeated movement of the hook 23* in the direction indicated by the arrow M* will carry the loop 0* of warp clear of the hook 9* and be about to pass it upon the loop R and the parts will arrive in the positions in which they are indicated in Fig. 15, when the cycle of motions for forming one link of the chain will have been completed.

I have confined my description to forming the chain at one side only of the machine, and the motion and action of the parts at the op posite side of the machine being similar to and alternate with those above described, a further description thereof will be unneces' sary. A portion of warp, chained or linked, as above described, is shown by Fig. 16, which is a diagram of a portion of warp when chained or linked. The warp to be chained or linked by the machine above described may be formed upon a warping-mill or beamingmachine, by which threads are usually formed into a warp.

Another method of actuating the trumpet w is shown by Figs. 17 and 18, Fig. 17 being a front view and Fig. 18 a side view. To parts which are similar to parts previously re ferred to I shall afiix the same letters of reference as I have affixed to similar parts above mentioned.

j is a vertical shaft, which imparts rotary motion to the shaft 47 by means of the bevelwheels 48 49. Fast upon the shaft47 is a bevelwheel, 50, which gears into another bevelwheel, 51, fast upon a shaft, 52, mounted and capable of being rotated in brackets secured to the cross-frame or cross-beam 53. Fast upon the shaft 52 is a cam, 54. To the crossframe53aresecured \I-guides 55, within which and capable of being slid therein is a plate, 56. Upon the plate 56 is mounted a stud, upon which is mounted a bowl or roller, 56.

Secured to the plate 56 is a stud, 57, from which depends a rod, 58, the lower end of which is connected by the universal joint 59 to the arm n, jointed to the arm a fast upon the shaft i. To the arm 7; is secured the trumpet w. The rotation of the cam 54 will cause the arm 1) and the trumpet w to be raised and lowered in a manner similarto that previously described.

In some cases I propose to form a chained or linked warp by means of the above-described ehaining or linking apparatus or ma chine by taking the yarns or threads from which the warp is to be formed direct from the bobbins upon which such yarn or thread has been spun or wound. For this purpose I pass the threads or yarns between or around rollers,which, by means of their revolving surfaces, draw off the yarns or threads from the bobbins aforesaid, and deliver the said yarns or threads to the linking or chaining apparatus or machine. The yarns or threads aforesaid, in their passage from the bobbins previously mentioned to the chaining or linking machine or apparatus, pass through a heck or similar apparatus for arranging the yarns or threads in an order suitable for weaving. After the warp has been chained or linked by the machine or apparatus above described, it may either all upon the floor or other surface beneath the chaining or linking machine or apparatus to be subsequently removed, or the said warp may be passed over suitable pulleys or guides to be conveyed thereby to any convenient place. The said pulleys may have rotary motion imparted thereto, if desired. This arrangement of apparatus is shown by Fig. 19. Ais the creel, in which are placed the bobbins containing the yarns from which the warp is to be made. B is aheck, and O C are rollers or rods, such as are ordinarily employed for taking up the slack yarn or thread in beaming machines. The yarns or threads are passed through the heck B, then overand under the rollers or rods 0 to the rollers E E, and thence to the trumpet w ofthe chaining or linking machine.
