LASTiNG-MACHINE.

Specification of Letters Patent.

Patented Dec. 21, 1999.

Application filed November 8, 1900. Serial No. 35,882.

To all ivhom "it may concern: Be it known thatI, WILLIAM EcWAon, of Rockland, county of' Plymouth, Commonwealth of Massachusetts, have invented cerr and particularly to that type of lasting machines by which the upper is worked over a 'laststep by step by the operation of the "machine on different portions of upper materials successively.

The invention as herein shown is applied to a lasting machine similar to that shown in United States Letters Patent No. 584,74 i,

of June 15, 1897, to which reference may be had for am'ore complete description of the construction and the several operations of the machine than is necessary to present in connection with the present invention.

This invention is an improvement upon the machines shown in United States Letters Patent No. 696,717 and No. 696,740, of

April 1, 1902, and it has for its object to provide improved means for -applying wire or other suitable continuous material, which will herein be referred to as wire, to a shoe for holding the'worked-over upper material in lasted position.

A very important feature of this invention consists in providing a machine for working'an upper over'a .last with means for feeding wire to bind the worked-over 40 terial and has provision for advancing the wire automatically from a wire holder, whereby-the operator is relieved of the labor heretofore required for drawing the wire from the wire holder.

In the embodiment of the invention herein shown a reciprocating presser is, cinploycd for forcing the worked over portions bf upper material into the angle of union between the feather and lip of the in- .50 nersole of a weltedshoe and a wire supporter is mounted on the reciprocating presser and coiiperatestherewith and preferably with a fixed presser in superimposing the wire in position to bind the upper into said angle of union or against the lip of the .man.

innersole. Thewire supporter mounted upon and moving with the reciprocating presser serves to pull the wire from the wire holder and advance or feed the wire into position to'be superimposed. By this construction the wire is advancedat each operation of the wire-superimposing means, and, in the machine to which the invention is shown as applied, the advancin or feeding of the wire also occurs norma ly at each operation of the over-working mechanism.

It will be understood that the invention is not limited to a construction in which the wire is advanced and superimposed by the same or closely associated parts, for obviously it is within the scope of my invention to advance the wire by means of mechanism which is .entirely independent of the mechanism for superimposing the wire. A further feature of the invention consists in providing the machine with mechanism for taking up slack Wire after each operation of advancing and superimposing the wire and before the next wire-advancing operation.

Still a further feature of the invention consists in providing improved means for producing tension on the line of wire supply whereby too free delivery of wire from the wire holder is revented. Preferably, also, means is provit ed under control of the operator for varying the tension on the wire. As herein shown, connections are arranged between the tension mechanism and a foot lever whereb the tension may be increased ,at thewill o the operator to enable him, by a manipulating thp shoe to which the free end of the wire s attached as hereinafter cxplained, to draw :the wire tightly about the worked-over portions of upper material.

In accordance with another feature of my invention, I have provided means for rendering the w re-advancing mechanism operative or inoperative at the will of the work- In the machine herein illustrated mechanism is provided for causing the overv tions of parts will be hereinafter described '2 is a side elevation of the base of the machine and certain parts concerned with the present invention and which later will be more fully described; Fig. 3 is a section on line 3 of Fig. 2; Fig. 4 is a'perspective view of the wire-cutting devices with which the machine is equipped; Fig. '5 is a plan view of the work pressers, the wire holder, the take-up, and other parts connected with the inven-' tion; Fig. 6 is a similar view showing cer tain of the parts in different position from that shown in F ig, 5; Fig. 7 is'a view similar to Fig. 5 and illustrates the positions occuied by certain parts when the wire-advancing mechanism has been rendered ino erative; Fig. .8 is a bottom plan viewo the ,forepart of a lasted shoe; Fig. 9 is a section of line 9-9 of Fig. 8; and Fig. 10 is a perspective View showing particularly the mechanism employed in the described machine for actuating the grippers.

In the machine to which the invention is herein illustrated as applied, the upper is manipulated over the last by means compris ing gripper members 80, 81 which are suported by carrier 82- suspended from the front end of the lever 83, by which vertical movements are imparted to the grippers for updrawing' the upper. The updraw lever 83 is fulcrumed in the frame of the machine and is connected at itsrear end (see Figs. 1

and 10) to a cam 84 on the main shaft D. The grippers are closed by a cam 54 on the shaft D which acts .through a rockshaft 55 to depress a bar 56 for moving the gripper member 81 toward the member 80. The gripper carrier 82 is guided through a yoke 85 moimted on the front end of a horizontal bar 86, the rear end of which bar is engaged by a spring-actuated arm 87 by which the grippers are pressed forwardly for drawing the upper over the last bottom. A cam face on the side of block 54 engages a stud 57* on a bar 86 for drawing the'grippers toward the machine into positionto grip the upper on the edge of thelast bottom.

For the best results in manipulating the upper over the-last at the toe, and sometimes at other portions of a shoe, the grippers require to be moved laterally and turned for laiting the upper, and to this end a' knee ever 68 has connections through a rockshaft 71 with a shaft 76 for throwing into and out of operation the mechanism for moving the grippers lateraiiy and turning them to plait ythe. upper.

These several mechanisms for actuating and controlling the grip ers are fully illustrated and described in etail in said Letters Patent No. 584,744, which gle of union between the feather and lip of the inner sole of welted shoes. The pressers are arranged for longitudinal movement toward and from operative position and are actuated rearwardly toward their inoperative position by springs 00, 50 A slide bar 35 is arranged to engage rolls on the rear ends of the pressers, and has notches into which the rolls enter when the bar occupies the position shown in Fig. '7. Inclined faces connect the notches with the higher portions of the bar, and by shifting the bar longitudinally the pressers are advanced from their inoperative position to their operative position, shown in Fig. 5. The shifting of the bar 35 is effected by a lever 33 having connection with the rockshaft 71 before described as being manually controlled for the purpose of rendering the gripperoperaengagement with a cam 57 on the main shaft D. The driver has a head 27 which is guided in a slide x having connection with the lever 33 on rockshaft 71 before referred to. The adjustment of the rockshaft which causes the pressers 36 and 38 to assume their inoperative position also moves the slide w (as shown in Fig. 7) so that the driver head will reciprocate between the pressers without actuating either of them. An adjustment of the rockshaft which advances the pressers into operative position also shifts the slide 00 to place the driver head, as ill-ustrated in Fig. 5, in position to engage a shoulder on the presser 38 and impart to that presser an advance movement toward the shoe at each operation of the machine. Reverse movement of the presser 38 is effected by the spring an. In its advance movement the presser 38 engages the portion of upper material-being acted upon .by the grippers and forces it into the angle of union between the feather edge and lip of the inner-sole. The presser 36 preferably remains at rest u on a portion of the upper material previous y worked-over.

The construction and operation of the pressers as above described is substantially the same as is described in the Letters Patent No.' 584,744 before-mentioned. The present invention contemplates that the upper material thus 'rnanipulated into lasted position shall be held around the toe of the shoe by a strand of wire or other continuous .on the wire.

material extending from a tack on one side of the shoe around the toe to a tack on the opposite side, the wire binding the successively-manipulated portions of upper material against the lip.

In the machine shown the wire is supplied from a reel 2 mounted on a stud on the frame I? of the machine. as shown in Figs. 1 and 5, and has its mot-ion retarded by friction between a spring-pressed plunger 4 carried by the reel and the face 6 of the frame. The tension means for acting upon the line of wire supply comprises a rod 10 mounted in the frame B, as shown in Fig. 3. A spring 16 is held under compression between a nut 12 on the upper end of the rod and a disk 14. Resting upon the frame B is another disk 22, and between said disks is a drum 18, the hub of which extends into the disk 22 and the flange of which overlaps said disk so that the wire 20 passing from the reel around the drum (as shown in Fig. 5) is gripped between the disk 22 and the flange of the drum with a force dependent upon the degree of compression of the spring 16. Preferably the rod 10 is arranged to be moved longitudinally in the frame at times to increase the compression of the spring 16 and thereby increase the. tension To this end the rod 10 is extended below the frame where it is provided with a suitable head to limit its upward movement, and a connecting rod 26 extends from the rod 10 to a treadle 28, by which the rod 10 can be pulled downwardly for applying increased tension to the wire.

The free end of the wire is, in practice, securedto a tack at one side of the shoe, and the shoe presented in the hands of the operator in the position shown in Fig. 5, where the reciprocating presser, in its advanced movement will engage the strand of wire and superimpose it on the upper for holding in position the successively-overworked portions of upper. The shoe is advanced and turned step by step for presenting the diifei ent parts of the upper in position to be overworked and for the wire to be superimposed for securing said portions' In the present embodiment of the invention the wire is supported and guided by a device 40 which, asv herein shown, is Secured to the presser 38 and partakes of the reciprocating movements of said presser.

The supporting device 40'deflects the wire from a straight line, and at each advance of the reciprocating presser serves to pull the wire from the wire holder and advance or feed it-toward position to be superimposed. Of course the wire guide as it advances and carriesthe wire towardthe shoe draws upon the portion extending 'to' the' slroe as well as uponthe portion running to the tension and so tightens the wire into binding relation to the upper between the shoe and the presser 38, which, as it advances, crowds the upper and the wire into the angle between the feather and the lip of the innersole and firmly seats the wire which is thereafter held in position by the presser 36. It will be understood that in the illustrated machine the wire is advanced at each operation of the' upper-manipulating means and the wiresuperimposing means, and that the wire-advancing means is operative when the upper- ,plaiting mechanism is operative. and is in shown in the drawings, and is acted upon by a spring-pressed plunger 64 for holding it normally in the position shown in Figs. 5 and 7, with a-shoulder on its hub against a stud 66. When the presser and wire supporter advance, the pull on the wire will first overcome the pressure of the spring plunger (Stand turn th earm 60 into the position shown in Fig. 6, in which it en.

gages the face on the frame. Continued advance of the wirefeeding means will then draw the wire through the tension means from the line of wire supply. hen the presser and wire supporter retreat from the shoe, the spring plunger GI will force the swinging arm toward the position shown in Figs. 5 and 7, thereby taking up any wire not required for binding the portion of upper manipulated into lasted position by the last operation of the machine. \Vhen the lasting of the toe of the shoe has been completed, the wire is wrapped around a tack e to secure it and then is cut from the line of wire supply. Cutters for severing the wire are conveniently carried by the frame B. To this end a cutter blade 30 is directly secured to the frame, as shown in Figs. 2 and 3, and a blade 32 is movably connected to the blade 30 and is secured to the head of the rod 10, whereby it may be actuated by the treadle 28 for cutting wire.

In the use of the machine for lasting the toe of a shoe, the knee lever 68 is actuated for turning the rockshaft 71 to render the grippers operative for plaiting the upper. This actuation of the knee lever also advances the presser- s 36, 38 into operative position and shifts the driver head 27 into position toengage and actuate the presser 38. The free end of the wire is then fastened to the tack a and the shoepositidned in proper relation to the grippers'and the presser, the wire necessary to perm-it this -ot' the spring 10 positioning of the shoe being drawn from 1 means for creating atension on the line of the-wire holder again- 1e normal tension ernuned by the ad ustlVhen the machine is ment of nut 12.

started the grippers pull the upper over the advances, the wire supporter 4:0 is also-carried forwardly and pulls or feeds the Wire from the wire holder. \Vhen the presser and wire supporter retreat, the arm 60 takes up any wire not required by that operation of the machine. After each operation the workman advances the shoe the desired distance to present another portion of the upper in position to be operated upon, and in advancing the shoe he may manipulate it so'as to draw the wire tightly aboutthe upper. The treadle 28 may, at suchtimes, be depressed for applying additional tension to the line of wire supply to enable the superimposed wire to be drawn as firmly. as desired about the over-worked portions of upper. hen the lasting ofthe toe is completed, the Wire is secured to tack e and cut' from the line of wire supply.
