To all whom it 'may concern:

Be it known that l', GnmcoN Anisro'rnn MENENDIAN, a citizen oit the United States of America, residing at Cleveland, in the county ot Cuyahoga and State ot' Ohio, have invented certain new and use't'ul Improvements in Looms; and I hereby declare the following to be a full, clear, and exact deseription of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to improvements in knot-tying mechanism for looms Ylor making oriental rugs, carpets and the like.

The object of this invention is to provide a. loom capable ot producing a carpet or other fabric having a heavy tufted sur't'ace similar to that produced by oriental weavers.

W'ith this object in View, my invention consists in providing in combination with a loom adapted to weave a suitable body fabric mechanism for knotting tuitts ot' yarn into the said body fabric during the weaving process.

My invention also consists in the features of construction and combinations ot' parts as illustrated inthe drawings and hereinafter described in the specification and pointed out in the claims.

By referring to the drawings, it will be seen that my improved loom comprises a main stationary frame on which are mounted the heddle trames which are arranged to operate in the usual manner. A vertically arranged frame is pivotally mounted at its lower end in the main frame so that it is t'ree to rock therein. This frame extends from side to side of the main frame and carries a series ot vertically arranged stationary spacing rods, each of which is provided with a small projection or bracket. The proj eetions or brackets serve as supports for the yarn from which the knots or tults are made as will be explained hereat'ter. At each side ot each spacing rod is arranged a llat resilient strip or bar which is free to slide in said rocking trame so that each spacing rod lies between a pair ot' said bars, and the bars forming each pair ot bars are pret'- erably connected at their upper ends lorming elongated inverted U-shaped members which of course are free to slide vertically in said rocking frame. A projection or jaw is arranged on each bar and extends ttorwardly therefrom and therefore each U- shaped member carries a pair o'l said jaws and when the U-shaped members are in their upper or normal position in the rocking trame the jaws on each U-shaped member are above the bracket on the spacing rod within the U-shaped member. Means is provided for holding the bars in their upper position so that each pair of bars,-that is, each U-shaped me1nber,-may be permitted to move down in the rocking frame as desired. As shown, this means comprises a series ot levers which are fulcrumed at'one end in the main stationary frame and to each ot' which one of the U-shaped members is operatively connected. The free ends ot the levers rest on a drum, the surface of which is partially cut away 'forming a series oi openings and the openings are so arranged that when the drum is rotated the support for each lever will be successively removed so that one lever will drop at a time, which permits the U-shaped members to move down in succession accordingly.

Mounted on and extending horizontally across the front of the rocking 'frame below the bracket on the spacing rod is a member or bar in the upper edge of which are 'tormed a series of V-shaped notches each ot which is designed to receive a pair ot jaws on a U-shapcd member and canse said jaws to converge and grip the knot or tut't forming yarn when the U-shaped member moves down as will be explained later. The reel that carries the warp threads is mounted on the rear end of the main frame and the threads are then carried downwardly through the heddle frame and through the rocking trame to a reel, at the front end of the main frame on which the woven fabric is wound. The warp threads are carried through the rocking frame in pairs, each pair passing through a U-shaped member, one thread passing at one side and the other thread passing at the other side ot the spacing rod. The knot or tutt forming yarn is carried by a spool mounted near the top at one side of the rocking frame and the yarn is brought down around a small pulley and laid along the top ot the brackets on the spacing rods and therefore under the jaws on the U-shaped members and the end ot the yarn is secured in a clip on the side of the rocking trame opposite to the side on which the spool is mounted.

Mounted in the upper part of the trame near the front of the machine is a sliding carriage which extends from side to side of the frame. This carriage is provided with a number of slender needle-like rods which correspond with the number of knots to be tied. These rods are revolubly mounted in the carriage and extend forwardly and rearwardly of the carriage and terminate in hooks at their rear ends. The opposite or forward ends of said rods are flattened and have a slight twist. These ends pass through openings in the stationary bar which extends across the front of the machine, and the openings are so arranged or shaped as to impart a quarter revolution to the rods or spindles when the carriage reaches its limit of travel rearwardly, that is toward the rocking frame so that the hook is turned from a vertical to a hori- Zontal position. This carriage travels on an incline in the direction of the lower rear part of the machine, and the warp threads incline toward the lower front part of the machine and therefore the two approach each other and the inner or hook ends of the rods on the carriage pass downwardly and rearwardly through the warp threads when the carriage is advanced. A sliding carriage extends transversely of the frame and thereon is mounted a series of knife-blades which correspond in number to the number of U-shaped members. These knives are arranged to cut the yarn between the knots after the knots have been tied when the carriage is advanced by the means provided for that purpose which will be particularly described later.

In the accompanying drawings Figure 1 is a side elevation of the machine before being operated. Fig. 2 is a similar view with part broken away but showing one of the U-shaped members in its lowest position and with the hook bearing carriage and the knife bearing carriage partly advanced. Fig. 3 shows the parts in the same position as F ig, 2, except that the hook bearing carriage has been farther advanced so that the hooks thereon are in position to engage the tuft-forming yarn and the knives on the knife-bearing carriage are slightly inserted in the loops of the tuft-forming yarn. Fig. l is a similar view but showing the hook bearing carriage drawn back and the tuftforming yarn engaged by the hook and also the knife-bearing carriage drawn back with the loop of the tuft-forming yarn on the blade. Fig. 5 is a similar view but showing the hook bearing carriage drawn back a little farther while the knife-bearing carriage has remained stationary which has caused the severing of the loop on the knife. Fig. 6 is a top plan of the machine. Fig. 7 is a section on line 77, Fig. 1. Fig. 8 is an enlarged front view of one of the U- shaped members with part broken away and the inclosed spacing bar together with two warp threads and a portion of the tuftforming yarn, also showing the end of one hook in a vertical position. Fig. 9 is in all respects similar to Fig. 8 but showing the hook in a horizontal position. Fig. 10 is similar to Fig. 9 showing the tufting-yarn withdrawn from the bracket by the hook. Fig. 11 is a similar view showing the yarn cut and the ends drawn up to form the tufts.

Again referring to the drawings 1 represents the stationary frame at the back of which is mounted a reel 2 from which the warp threads a are carried downwardly and acrossI the frame to a reel 3 mounted at the front of the frame and on which the fabric 1s wound as woven. In the lower part of the frame near the center thereof is pivotally arranged a rocking frame comprising two .vertically arranged side-pieces 5 which are joined together by cross rods 6 and 7 one at the top and the other half way down. On the ' cross pieces 6 and 7 are rigidly mounted spacing rods 8 each of which is provided with a forwardly extending projection or bracket 9. A series of U-shaped members 10 having slots 11 through which the .cross pieces pass are mounted in the rocking frame so as to move freely up and down therein and the side pieces or bars of each U-shaped member inclose a spacing rod 8. Onthe side bars of each U-shaped member 10 1s arranged a jaw 12 so that each U- shaped member carries a pair of such jaws, and when the U-shaped members 10 are in their upper position the jaws 12 are above the brackets 9, and when the U-shaped members 10 are in their lower position the jaws 12 are below the brackets 9. In the lower part of the frame below each U-shaped member is arranged a lever 13 one end of which is fulcrumed on a shaft 14:. In each lever 13 is formed a slot 15 and a pin 16 is passed through the lower end of each U-shaped member and through the slot 15 in the lever 13 thereunder, so that each U-shaped member is operatively connected to a lever 13. A drum 18 is mounted below the free ends of the levers 13 so that the free ends of the levers may rest thereon, and a portion of the surface of the drum 18 is eut away, as at 19, making a sort of step-formation so that when vthe drum is turned by any suitable means, (not sho wn,) the support beneath the free ends of the levers 13 will be successively removed permitting the levers to drop down consecutively from left to right and the U- shaped members which are secured to said levers will move down in succession accordingly, and the extent of movement is such that the jaws 12 on the U-shaped members will move from their normal position above the brackets 9 on the spacing rods 8 to a position below the brackets 9. On the upper end of one of the sides 5 of the rocking frame is secured a spindle 20 on which is mounted a spool 21 which carries the yarn c of which the knots or tufts are to be made. On the end spacing rod adjacent to that side of the frame on which the spool 21 is mounted is arranged a small pulley or gnide sheave 22 and on the end spacing rod at the opposite side of the frame are mounted a pair of spring jaws 23; the pulley Q2 and the jaws 23 being about in line with the brackets E) on the spacing rods 8 and therefore below the jaws 12 on the U-shaped members 10. The yarn c from the spool 2l is carried beneath the pulley and is laid along on top ot the brackets 9 on the spacing rods 8 and the end of the yarn is secured between the jaws 23. A plate 25 is arranged across the rocking frame at a suitable distance below brackets 10 and in the upper edge thereof are formed a series of V-shaped notches 26, each of which is arranged to re ceive a. pair ot jaws 12 on a U-shaped member when they are in their lowered position and cause the jaws to close.

It will be readily understood that, as the drum 1S is turned permitting the levers 123 to move down, the U-shaped members nearest to the jaws 23 will move down tirst and the jaws 12 thereon will pass down on opposite sides of the bracket t), on the spacing rod S inclosed by said U-shaped members, and said jaws will also pass on the outside of the pair of warp threads which pass through said U-shaped members and therefore the tutt-'forming yarn is carried down around the bracket 9 and on the outside ot the warp threads and when the jaws have passed below the warp threads they enter a V-shapcd notch in the plate 25 and are caused to converge and grip the tutt-torming yarn as shown in Fig. S. Crank arms 8O are mounted at each side ot' the trame below the reel 2 and links 231 are secured to these arms and to the lrocking trame and when thel rocking frame is in its backward or normal position the arms will abut against stops 32 which limit the backward movement oit the trame and this arrangement serves to brace the rocking trame while permitting it to rock torward so as to pound the woven :fabric atteia row ot knots has been 'tied or aftter a woo't thread has been passed through the warp threads.

Before leaving the description ot' the rocking frame it may be mentioned that spaeu ing rings P54v are arranged on the cross bars and t between each U-shaped member and between the side bars oit lthe U-shaped members and the spacing rods.

On the side bars ot' the frame 1 are arranged inclined strips 3G which Vlorm a slideway for the knit'e carriage. This carriage comprises two side pieces 3T and a cross member 3S which extends across the top ot the frame 1. The side pieces Si' are arranged on the outside oit the side bars ot the 'trame 1 and rest on the strips 3G and are inclined to correspond to the inclination ol said strips. On the cross member 38 are rigidly secured a series ot knives 39 which are so located that the knives are in line with the spaces between the U-shaped members. In the top of each side bar oi the frame .l is formed a small groove or guide` way 4:0 and in each guidcwav is arranged a sliding block ftl. A, link extends trom each block to the adjacent side ot the knife carriage and this arrangement serves to hold the knite carriage on the strips flt while permitting the carriage to slide t'reely on the said strips. At the front end oi the 'trame 1 above the side bars thereof are arranged two brackets 4111 which 'torni the support and slideway 'for the hook carrying carriage -l-5 which consists ot a bar extending from side to side oil. the trame 1 and provided with lugs 45 which extend down into guidewavs atl :formed in the bracket tl. rlhe guideways Llet have a slight swerve or bend .near their rear ends. n the carriage Lt5 are mounted a number ot needle-like rods /l-t which are arranged to turn t'recly in the carriage but are fixed against longitudinal movelnent in the carriage. ()n the rear ends ot the rods Litt are t'ormed hooks -t7 and the iront. or outer ends ot' said rods are tlattened and a quarter-t\vist is imparted to each, as at 4S. (ln the brackets #llt is mounted a stationary cross bar 50 which is provided with a horizontal slot or opening 51 through which the rods l-t pass and when the carriage is advanced, by the means hereinafter described the twisted ends oi the rods will be drawn through the opening in the bar 50 thereby producing a quarter turn ot each rod, which changes the position ot the hook thereon itrom vertical to horizontal. The rods are so mounted in the carriage that when the carriage is at the 't'ronlfo'l the 'lrame the rods are in line with the tulttoi-ming yarn extending between the brackets 9 and the jaws l2, but when the carriage is advanced the turn in the gllideways will shitt the carriage transversely oi the 'traine and the hooks will pass to one side ot the yarn.

To each side oil: the carriage l5 is connected one end of a link 58 the other end ot which is connected to a crank arm journaled on the 't'ront end of the trame l, and therefore b v taking hold ot the arms 5t the carriage can be moved back or torward as desired. A rigid arm 55 extends down at each side ol the carriage 45 and has a horizontal extension 5G and a vertical extension 57. To the horizontal extension 5G is pivotally secured a depending pawl or dog 58 which can only swing toward the extension 57. )n each side ot' the knife-carrying carriage is mounted a pin 59. Now as the hook carrying carriage is advanced the pawls 58 lltr will pass over the pins 59 and there will be no movement. of the knife-carrying carriage until the vertical extensions 57 come in contact with the pins 59 and then the hookcarrying carriage and the knife-carrying carriage will travel together the full rearward movement of both, that is until the points of the knife blades are inserted within the loops of the tuft-forming yarn. Then when the hook carrying carriage starts to move in the opposite direction it will travel a short distance, thatis the distance between the vertical extensions 57 and the pawls 58 before the pawls 58 vengage the pins on the knife carriage during which time there will be no movement of the knife carrying carriage and therefore the movement of the hook carrying carriage will pull the loops of the tuft-forming yarn farther up on the knife blades. When the pawls 58 come in Contact with the pins 59 the knife carrying carriage will start to move with the hook carrying carriage and will continue to move with the hook carrying carriage until it has moved forward and down so that the pawls clear the pins on the knife carrying carriage when the knife carrying carriage will become stationary while the hook carrying carriage will continue to move pulling the loops of the tuft-forming yarn along the knives until they are severed. At the rear of the rocking frame is arranged a casing 60 for the heddle frames which are mounted so as to slide vertically therein. The heddle frames may be shifted in the usual manner to separate the warp threads either by hand or in any preferred way but as the same does not form a part of this invention further description is not deemed necessary. Y

Before the machine starts to operate all the parts are as in Fig. 1 and the Warp threads extend from the reel 2 downwardly across the frame to the reel 3. The warp threads passing through the rocking frame in pairs and each pair passin0` through a U-shaped member and one thread of each pair passing at each side of a spacing rod. The tuft-forming yarn I) as before mentioned is brought down from the spool 21 and laid along on top of the brackets 9 on the spacing rods 8 and therefore extends along under the jaws 12 on .the U-shaped members 10. The heddles are first operated to separate the warp threads and the woof thread is shot across by hand between the warp threads. rllhe drum 18 is then rotated and the lever on the side of the frame opposite to the side on which the spool 21 is mounted will move down first, drawing down the U-shaped member connected thereto and of course the aws on the U-shaped member will move down one passing at each side of the bracket 9 on the inclosed spacing rod 8 and therefore the tuft-forming yarn will be folded down around the bracket 9 and around the pair of warp threads passing through said U-shaped members. As the U-shaped member moves down the jaws thereon enter one of the V-shaped notches 2G in the plate 25 which causes the jaws to come together and grip the tuft-forming yarn, as shown in Figs. 8 and 9. Of course as the aw 12 moves pulling down the tuftforming yarn the spool 2l rotates permitting the tuft-forming yarn to feed freely and when all the U-shaped members are in their lowest position the tuft-forming yarn will be so disposed that there will be an upper row of loops thereof which extend over the brackets 9 and around each pair of warp threads and a lower row of loops thereof which simply extend from one pair of jaws on a U-shaped member to the next pair of jaws on the adjacent U-shaped member. As the drum continues to rotate the other levers will move down in succession until all the U-shaped members are lin their lowest position. The hook-carrying carriage is then advanced shoving ahead of it the knife-caru rying carriage, in the manner before described, until the knife blades on the knifecarrying carriage extend between the U- shaped members and are therefore over the lower row of loops of the tuft-forming yarn, and as the hooks on the hook-carrying carriage continue to move the hooks will pass behind the portions of the tuftforming yarn which extend down from the brackets 9 to the jaws 12 and the hooks will be turned from their vertical position to their hori- Zontal position, as before described, and when the hook-carrying carriage starts in the opposite direction that is toward the front of the machine the hooks will catch hold of the yarn and draw it out between the warp threads of each pair of warp threads. As the hook-carrying carriage continues to move toward the front of the frame the tuftforming yarn will be pulled from the bracks ets 9 and the lower loops will be pulled up on the knives. The drum 18 is again turned so that all the levers are raised simultaneously thereby lifting the U-shaped members and freeing the yarn from between the aws thereof and as the hook-carrying carriage continues to move back after the knife-carrying carriage has ceased to move, as before described, the lower loops of the tuftforming yarn will be drawn along the edges of the knives thereby severing the loops and the free ends thereof will be pulled up by the hooks and will form the tufts. The heddles are again operated and another woof thread is passed across after which the rocking frame is moved forward to beat-up the woven material in the customary manner.
