The machine i lustrated in the drawings', like the machine disclosed in the patent above referred to, is adapted to pass a series of loops formed in a lacing cord through` the eyelet holes of an upper, and thereafter to pass a portion of the lacing cord throu h the loops, sever the lacin -irom the supp y and tie the ends of the lacin together. The machine coin rises a plura ity of needles, equal in numher to the number of pairs of eyelet holes which it is desired to lace, a plurality of looperI fingers coperatin .with the needles to form the lacing cor into loops and retain the loops in osition until the shoe upper is laced on t e needles, a cord-feeding neede to place the cord in position to e en aged by the needles and looper fingers an to pass a ortion of the cord through the loops after t ey have been eea, los

inserted in the eyelet holes of the upper,

Acord clamps or grippers to hold the ends of vthe lacing, a cutter to sever the lacing from .cord `throuh the eyelet holes or the upper `ivvitl'iout `di culty, the eye or slot ot cach -needle which receives the lacing cord is located a 'short distance'from the end of the :needle and Aopens at one side of the needle, nothat no projection is formed in the needle which can engage the eyelet or upper. "lfhe .-lacing cord is placed by the cord feeding yneedle-at one side of the looper needles, and i.to cause the cord to be engaged hg, the needles .a relative lateral movement of the ycord and needles is produced by moving the Acarrier in which the needles arc mounted. The needles are mounted in their carrier so as to be adjustable vvith reference to .each other to suit the spacing of the eyelets in the upper to be operated upon and to permit the adjustment of the needles to be made easily and quickly means are provided whereby the required adjustment of all of the needles is made simultaneously. To form the lacing cord `into loops the needles and looper fingers are moved longitudinally in opposite directions. The length of cord taken up by `the loops remains in the lacing and provides suliicient amount of slack in the lacing to permit the upper to be attened out and .properly fitted to the last. It will be evident that the amount ol' slack produced in the lacing can be varied by varying the length of cord talrenup in forming the loops vand in the machine illustrated in the drawings this is accomplished by adjusting the looper lingers longitudinally, means being provided -whereby ll the looper fingers can be adjusted simultaneously.

Two cord clamps or grippers are provided located at one side of the looper needles and looper fingers, one gripper being actuated to grasp and hold the free endofthe lacing cord, .and the other gripper being actuated to grasp the end of that portion of the cord which is passed through the loops of the lacing. 'lo enable these grippers to grasp the cord with certainty, they are arranged to operate in close proximity to the path of the cord feeding needle, and at'substantially the same distance therefrom. By this arrangement of the grippers and cord feeding needle the-cord is presented accurately to one 0r the other of the grippers at each reciprocation of the needle.

The means for severing the lacing from the supply of lacing cord consists ol a cutting blade mounted upon one of the cord grippers across the edge of which the cord l is dratvn during the backward movement of the cord feeding .needle after the lacing of the upper has been completed. A. sullicientl tension is put upon the cord to cause the cutter to sever the lacing by means ot an intermittently acting tension device which engages the cord during a portion of the backward movement of the cord feeding needle. l

The knot tying mechanism is located at one side of the looper needles and looper lingers between the needles and the oord grippcrs. ThisV knot tying mechanism is adapted to tie the ends of thc lacing together in a certain and reliable manner, and permits the laced upper to be dropped from the machine Without any liability of interfering with the subsequent operations oi" so the lacing devices. The novel features oit' this lrnotting mechanism consist in certain constructions and arrangements ol its parts which Will be hereinafter described..

In addition to the parts above referred to, the machine illustrated in the drawings is also provided with a knot tightener consisting of a linger which acts upon the lacing, While still held by the knot tying mechanism, to tighten the knot, and With a thread 9o p linger 'which acts upon the. cord between the looper needles and the cord grippers prior 'to the formation of the loops, and pulls out a length of cord which is used m forming y-the loops so that the cord for the.- loops is supplied from both sides of the needles and an excessive rendering of the cord through the eyes or slots of the needles is prevented.

To prevent the Work from projecting into the path of movement of the cord feeding needle, or from assuming any position which Would interfere with the operation of the machine Work guards are provided on each side of the looper needles, and one ol' these Work guards is adjustable toward and from the needles so that Ait may be brought into desired position with relation to the needles when the needles are adjusted.

The machine is also provided with a Work adjuster for forcing the upper into position l-lO on the looper needles, and with a. stop mech* anism for throwing the machine into and outof operation. The Work adjuster consista of plate mounted to move from a position at one side of the needles across the endsl of the needles and then longitudinally of the needles a sufficient distance to force the 'ipper into the desired position on the needles. The 'work adjuster also serves as ay guard to prevent injury to the hands ofthe laf operata' by the lacing devices, and particularly of 1he cord feeding needle, since the j hand of the operator cannot remain in the path of movement of the cord feeding needle during the movement of the Work adjusting plate across the ends of the looper needles. rlhe Work adjusting plate is actuated through connections which control the operation of the stop mechanism, and these connections 'are so arranged that the work 130 adjusting plate is brought into operation before the machine is thrown into operation. The correct j iositioning of the work is thu-1 insured, and also all danger of injury lo the operator is avoided.

Referring now to the drawings, and paiticularly to Figs. 2, 4 and 5, the nunieral 10 designates a frame including separated side members 11, 11., in which is mounted a shaft 12 carrying a yoke 13, to which are pivoted arms 14, 14 of the needle carrier Articulated to the under side of the forward end of the carrier is a link 16, in which may be included a turn-buckle 17, allowing an adjustment of the stroke' of the carrier, this 'link being pivoted at ,its opposite end to an angle lever 18, turning about a shaft 19 extending between the .sides of the frame. ln the end of the lever 18 is secured a stud 2O carrying a cam roll 20a, arranged in a cani path 21 formed in the face of a disk 22 fixed to the shaft 22a. The cam path imparts to the lever 18 and to the forward end of the carrier an angular movement which is most clearly shown in Fig. 4'9, there being a maximum downward position indicated at X, in which the needles are in position to receive rthe work and to have the work stripped therefrom, an cxtreme upward position indicated at Y, .in which the eyes or slots of the needles receive the lacing cord, and an inter` mediate or mean position indicated at Z, in

which the needles are in position to permit ,the passage of the cord yfeeding needle through the loops of the lacing. During the operation of the machine the needle carrier also assumes 'a fourth position slightly be,.- low tl? t indicated at Z, to allow the cord feedingneedle to pass over and in close proximity to the needles in feeding the lac-` i'ng cord' to the needles preparatory to the formation of the loops. 'Across the outer end of this carrier is a front-plate 23 (Figs.

3, 8 to 11, inclusive) forming a space iii which are situated square blocks or holders 24 for the needle spindles 31 that carry the needles 25. Five of these needles 25 are here shown, but it will be obvious that any desired number may he c...ployed according to how inany eyclet openings are to be laced. Each needle has at one side, near its outer extremity, a slot or eye 213 which extends longitudinally of the needle and opens at one side in a throat 27, which is formed by cutting away the wall of the needle at this point. Below cach slot t3 is a groove 28 that lies about 90 from the slot with reference to the circumfcreucc of the needle, these grooves 28 being provided to facilitate the passage of the cord carrying needle through thc loops of the lacing. l-ach needle is secured in its spindle by a set-screw 29, which secures thc needle in the tubular socket tl() of the spindleil. 'lhe inner-end of the spindles projects into a chamber 9:2- within the cari'ier. At the other end each spindle is l formed with a shoulder 33 that receives the set-screw 29 and prevents the inward movement of the spindle. A collar 34 secured to the end of each spindle 31, and located in l the chamber 32, prevents the outward inovenient of the spindle. From this collar projects a crank 35, having a crank-pin 36 by which each spindle in ay be rotated by mechanism. which will be hereinafter described. The block or holder 24 at the right of the plate, as seen .in Fig. 3, is fixed, while the remainder may beA adjusted with relation to one another to provide for the different p0- sitions of the needles, due to different spacings of eyelet holes in the upper. In the space at they rear of the front plate depend from each holder 24, pairs of separated arms or extensions 37, 37, connecting respectively j to those adjacent to' them at each side by I links 38. l'he upper ends of these links are l pivoted to the arms 37 at' B9, while the lower l ends carry pins 39h, operating in slots 39 in the ends of the arms 37, Fig. 1l. These links are articulated to one another at intermediate points 40 so that a lazy-tongs systcin is formed by which a proportionate ,movement is imparted to all the holders. To the outside holder ai'in at the left is pivoted a link 41 operating through aslot in the front plate, and being joined at its opposite end to an adjusting lever 42, fulcrumed upon said plate. In this lever is a quadrant slot 423, having extended through it a binding-screw 44, allowing the position of the lever to be adjusted. It will be seen that by this mechanism all the holders, spindles and needles may be simultaneously moved laterally, and the proper spaces between them secured and maintained. The needles 25 are moved longitudinally, to enable them to ef-i feet their share in the looping operation, by a reciprocation of the carrier through an oscillation of the yoke 13 that is provided with a cam roll 45, entering a cam path 46, in a disk i7. (Fig. 5) fixed to the shaft 22a.-

lhe looper fingers which coperate with the needles in forming the lacing cord into loops are mounted and actuated as followsr---ln the carrier 15 (Fig. 7) is formed a dove-tailed groove, or way 4S to receive and permit of the reciprocation of a complemental tongue 49 (Figs. 4 to 9 inclusive) formed on the bottom of a support 49, which is moved longitudinally of the carrier, to act uate the looper lingers, byl a connecting rod 50 that is pivoted at one end t0 the support 49, and at its opposite end to the lfi'ee end of a lever 12 pivoted on the shaft 12. The arm 12a cari-'ies a cani roll 51 arranged in a cam path 52 of a cam disk 53 fast upon the shaft 22a. At the forward end of the carrier are secured plates .15, which serve as guides for the Lfront end of the movable plate 5G upon which the looper fingers
