To alt whom it may concern:

Be it known that I, ARTHUR BATES, a subject of the King of England, residing at Leicester, Leicestershire, England, have invented certain Improvements in Lasting- Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to lasting machines, and more particularly to certain improvements in lasting machines of the t-ype disclosed in United States Letters Patent No. 584,744, dated June l5, 1897. ln the machine of saidv Letters Patent the upper is worked into lasted position by devices acting upon successive portions of the stock by repeated operations, such devices comprising pincers which are actuated to grip and pull the upper, and to lay it over upon the innersole, and a wiper which follows the movements of the pincers and wipes or presses the overlaid upper material smoothly upon the sole. The upper is secured in lasted position by tacks one of which is deposited in an aperture in the wiper by suitable devices prior to each advance movement of the wiper over the shoe, and Aat the completion of such movement the tack is driven through the lasted portion of the upper by a suitable driver. Machines of the type referred to are also provided with mechanism to impart to the pincers lateral movements, and axial turning movements, to plait the upper at those portions of the shoe where excessive fullness of the stock calls for such operation, the said mechanism being under the operators control through devices which enable him to vary the direction Aand extent of, as well as to initiate, or entirely suspend the plaiting movements at will.

A very important feature of the present invention consists in improved mechanism for wiping the upper into lasted position comprising a wiper which is so constructed and arranged for operation as to move in -an inclined path relatively to the edge of the shoe. When a wiper which is caused to move over the shoe in this manner is used in a machine of the type referred to its wiping or smoothing action upon the stock will conform better than heretofore to the direction of the plaits or folds produced at the toe of the shoe by the pincers when they are adjusted therefor, as described in said Letters Patent. Under one embodiment of the invention this result is secured by so mounting and actuating the wiper that it will be caused to swing laterally as it advances toward and recedes from the edge of the shoe, so that it wipes over the stock with a shearing action. The wiper may be conveniently supported for pivotal movement upon a carrying member which reciprocates the wiper, and be provided at a suitable point removed from its pivot with a projection which enters a guideway on a support rigid with the frame of the machine, the guideway being inclined to the path of movement of the wiper-carrying member. The arrangement of these parts is such that as the wiper is reciprocated toward and from the shoe the inclined guide way imparts a lateral movement thereto and causes it to swing about its pivotal support and wipe the leather along an inclined line whose direction and extent of inclination will be determined by the angle presented by said guideway to the path of movement of the wiper-carrying member. With the described arrangement of the guideway itl 'will be seen that the wiper is not only actuated in a direction toward and from the margin of the shoe, but is also deflected laterally to one side or the other of said direction of movement.

Under another embodiment of the invention the wiper comprises two independent members that are arranged for simultaneous movement toward and from the shoe in a direction substantially normal to the edge of the sole, and also along convergent paths that are inclined to the line of said first rier, and have their rear portions providedr with guiding slots which are entered by a pin or projection rigid with the frame of the machine. When the carrier moves inwardly toward the shoe and advances the wiper members over the edge of the sole the movement of the pin or projection along the guiding slots causes the wipers to approach each other in the manner of a pair of shears, and when the carrier moves away from the shoe a separating movementof the wipers is effected by the same means.

Another import-ant feature of the invention consists in providing means for varying the direction and extent of the deflected movement of the wiper relatively to the edge of the sole, said means being under the control of the operator. Preferably this means comprises an arrangement of the guideway, heretofore referred to, whereby it may be positioned in line with the direction of movement of the wiper-carrier when there will be no deflect-ion of the wiper, or may be inclined at varying angles thereto, or at either side of its central line, to cause the wiping movements to agree in extent of inclination, as well as in direction, with the plaits.

Still anotherfeature of importance comprisesthe provision of an operative connection between the means for varying the extent and direct-ion of the inclined movement of the wiper, and the means for rendering operative and controlling the mechanism which causes the pincers to form plaits or folds in the leather. This connection provides for such control of these parts that the lateral inclination or deflection of the wiper and the plaiting movement of the pincers can be adjusted in direction or varied in extent simultaneously by the operation of a single member. Conveniently this member may be a lever which is adapted to be actuvated by the knee of the operator, or it may be any other suitable device for the purpose.

Other features of the invention, including important details of construction and combinations of parts will be hereinafter more particularly described and claimed.

In the drawings: Figure 1 is a perspective view of the principal operative parts of a lasting machine with one embodiment of the present invention applied thereto, the supporting pedestal and frame being omitted; Fig. 2 is a detail view, somewhat enlarged, showing in perspective a wiper and its actuating and controlling devices; Fig. 2a is a detail view; Fig. 3 is a detail view of certain parts shown in Fig. 2; and Fig. 4 is a plan view illustrating a modification.

The main shaft 1 of the machine, which turns in suitable bearings in the frame, carries a cam block 2 which is provided with a cam groove or way to receive a roll on a slide 4 which is connected atits upper end to a rocking lever 5. This lever is fulcrumed at 6, and is connected at its forward end to the pincer bar 8, which is formed as a sleeve and carries at its lower end the aw 10. The

other pincer jaw 12 is connected to a rod 14 that extends upwardly through the sleeve 8 and is engaged at its upper end by a springpressed plunger 16 in a lever 18. The lever 18 is fulcrumed at 20 in the lever 5 and carries on its rear arm 21 a roll that rests upon an edge cam 22. The block having the edge cam 22 has also a cam groove inits front face to receive a roll on a lever 25, which is fulcrumed on a rod 26 and at its outer end carries a segmental rack whose teeth engage a pinion 28 on a sleeve shaft 30. This shaft is connected to a rocker 32 which carries a block 34 connected by the rod 35 with the cross head 36 by means of which the pincers are caused to move or swing laterally. A link 37 connects the said block 34 with a lever 39 which is fulcrumed throughan adjustable block, to a pin 41 supported from the frame of the machine. The upper end of the lever 39 is connected through a rod 43 with a rack which meshes with a pinion fast on the upper part of the pincer bar 8, whereby to effect the axial turning move ments of the pincers simultaneously with the lateral movements of the pincers in forming the plaits or folds, said parts being fully shown and described in the Letters Patent heretofore referred to. The cross head 36 is supported in a yoke 38 on the front end of a slide rod 40 which carries a roll that is engaged by the rear face of the cam 22. A spring 42, acting through a lever 44, holds the rod forward with the roll against the cam. A vertically reciprocating rod 50 which is guided in a boss 48 on a bracket supported from the frame of the machine, is pivotally connected at one end with an arm of a bell-crank lever 46, said rod carrying a roll which enters an inclined cam groove 52 at the inner end of a knee lever 54. The knee lever is fulcrumed at 56 on a pin carried by the machine frame, and is shown as having stop screws 58 which are threaded through bosses in the knee lever, and serve to adjustably limit its movement in opposite directions. The. bell-crank lever 46 is fulcrumed at 60 to the main frame, and is shown as having one arm formed as a yoke 62 which embraces a collar 64 connected through an inclined slot and pin, or the like, with a shaft 55 located within the sleeve shaft 30. The connection between the collar and the shaft 55 is such that a movement of the collar endwise on the sleeve serves to turn the shaft through a small angle. The

for controlling the direction and extent of such movements.

The mechanism described above for lowering and raising the pincers, closing them, and swinging forwardly and backwardly, and for eifecting their plaiting movements are fully described in the aforesaid Letters Patent, and of themselves form no part of the present invention. In the operation of these parts it is deemed sufficient to explain that the pincers with the jaws open are lowered by the cam 2 into position to seize the upper, closed by the cam 22, then uplifted by a further movement of the cam 2, and then moved forwardly over the shoe bottom by the spring 42. When the knee lever is set to adjust the block 34 in an eccentric position in the rocker 32 the pincers receive also lateral and twisting movements for plaitiiig the upper, the plaits being laid inclined in either direction from the median line of the shoe at the toe, or at the heel, according to the position into which the block 34 is moved by the knee lever.

A rocking lever 66 is fulcrumed at 68 to a bracket projecting from a rigid part of the frame 3. The upper end of the lever 66 carries a roll which operates in a cam groove formed in a cam block 70, which is fast on the driving shaft l. The lower end of the lever 6G is connected with a slide bar 72 which is suitably guided for horizontal movement in the machine frame and at its forward end carries a wiper to cooperate with the pincers in working the upper into lasted position. In prior machines of this type, similar parts to those just described are shown, the wiper being rigidly carried at the forward end of the slide bar, and being provided with an aperture to receive a tack. ln operation, the slide bar is reeiproeated to carry the wiper back and forth by the cam 70, and when it reaches a suitable position in its rearward movement a tack is deposited from a raceway by suitable devices in the aperture of the wiper, the wiper is then carried forward in proper time relation to the operation of the pineers, wipes the overlaid upper onto the innersole, and a driver forces the tack carried by the wiper through said parts of the shoe to secure them together. According to the present invention the wiper is not fixed to the slide bar 72, by which it is operated in previous machines of this type in a straight line toward and from the edge of the shoe, but is movably supported by the bar and operated in such manner that it has other movements imparted to it, whereby it may wipeV or press the upper in directions which will conform to the inclination of the folds or plaits in the upper at the toe or at the heel of the shoe, as will be now more particularly described.

The reciprocatory slide bar 7 2 has secured to its forward end a wiper carrier or support 74, and screws 76, which may pass through slots in the carrier and enter threaded openings in the slide bar, serve as a convenient means for providing an adjustable connection between said parts. The carrier 74 is shown as having a tackreceiving aperture 7 8, and at a suitable point preferably to the rear of its forward extremity is apertured to receive a stud or screw 80 from which the wiper S2 is pivotally supported at a point intermediate its ends. The wiper is shown as having a tackreceiving aperture which is so located as to register with the aperture 78 in the carrier 74 when the wiper occupies its central position, and is therefore in longitudinal alineinent with the carrie-r. To the rear of its pivotal connection with the carrier the wiper may be provided with a pin carrying.

an anti-friction roll 84, which is arranged to enter a groove or slot formed in a pivoted guiding member 88. This member is lshown as having cylindrical or arc-shaped portions 89 which rotate in similar curved guiding blocks 90, formed with or secured to a plate 92. This plate has upturned lugs 94 through which pass clamping screws 9G, having set nuts thereon, for adjustably securing the plate to a rigid part of the frame 3. From this construction it will be seen that the guiding member 38 may be moved to position its slot S6 in line with the center of the plate 92, which corresponds with the direction in which the slide bar reciprocates, or said member may be turned to' either side of said line so as to have the slot inclined to the right or to the left with reference to the direction of movement of the slide bar. With the slot arranged inclined, as shown for example in Fig. 2, as the slide bar is moved forward in the operation of the machine the wiper 82 will be turned on its pivot 80 by reason of the engagement of the roll 84 with the slot which will impart to the wiper a sidewise deflection or transverse movement, in addition to its forward movement, causing its active face to wipe the upper in an inclined direction relatively to the edge of the sole. Obviously the amount of transverse movement will vary with the angular displacement of the member 88, and the direction of the transverse movement toward one side or the other will be determined by the side to which the said member 88 is turned.

To effect the angular displacement of the guiding member 88 the latter, in the present embodiment of the invention, is shown as being connected by a link 98 with one arm 99 of a bell-crank lever 101, fulerumed at 100 in brackets projecting from the frame of the machine, said lever being operated, through connections to be described, by the mechanism that controls the plaiting movements of the pincers. As shown in F ig. 2, the lever 101 has an arm 102 that is provided with a bearing 104 in which a stud 106 is journaled, the said stud having a bearing 108 at its upper end which receives an extension of a stud 110 that forms a connection between one of the arms of the yoke 62 on the bell-crank 4G and the sliding collar 64. The studs 106 and 110 are arranged with their axes at right angles and are capable of sliding in their respective bearings so as to compensate for the curved paths in which the lever 101 and the yoke 62 move.

It will be seen that as the bell-crank lever 46 is rocked about its pivot 00 through the action of the knee lever the bell-crank will, through the connections described, cause the lever 101 to turn about its fulcrum 100 and consequently the link 98 to be moved to adjust the angle of the guiding member 88 and thereby cause the transverse or sidewise deflection of the wiper in the next movement of the slide bar 72, while at the same time the bell-crank 46 effects the plaiting movements of the pincers by sliding the collar 64 along the sleeve-shaft 30. The direction to which the wiper is deflected will depend upon the movement of the mechanism for effecting the plaiting operation, and the extent to which the wiper is deflected in either direction may be varied by a greater or lesser movement of the knee lever, it being obvious that any alteration of the lateral movement of the wiper due to this means, will effect a corresponding` alteration in the plaiting movement of the pincers. In order to provide for an adjustment of the extent of angular movement of the wiper relative to the plaiting movements of the pincers an adjustable connection may be provided between the link 98 and the arm 99 of the lever 101. As herein shown, a stud 112, connected pivotally with the arm 99, has an eccentric portion 114 to which the link 98 is pivoted. The stud 112 can be rotated, and then secured in dierent positions of adjustment by a set screw 115, so as to impart more or less movement to the link and hence to the guiding member 88.

'Vhile the wiper is deflected to one side or the other of the longitudinal central line of the machine, when the guide member is properly positioned to effect such movement, it is necessary that at its most advanced position the wiper should present its tack-receiving aperture 84 in alinement with the aperture 78 in the carrier and also in alinement with the driver 79 in order that the tack may then be driven into the stock. To this end the pivotal axis of the guide 88 is arranged coincident with the center line of the plate 92 while the guiding slot 86 extends outward and to the rear of said axis.

The inclination of the wiper will therefore be greatest when the wiper is in its extreme rear position, and as the wiper advances toward the shoe its lateral deflection or inclination will decrease gradually as the roll 84 approaches the end of its forward stroke, said roll at such time being in line with the axis of the pivoted guiding member and the wiper asa whole occupying a central position where its aperture 84 is in alinement with the aperture 78 and also with the driver 79.

In the modification shown in Fig. 4 the wiper comprises two independent, movable sections, which are so constructed and arranged for operation that when they occupy a retracted position said sections are extended laterally from the center line of the wiper-carrying slide bar, or actuator, and have their acting edges and faces inclined relatively to said line, but as said sections are advanced toward the shoe they are caused to approach each other and wipe the stock laterally along convergent paths that meet at said center line. In this construction, the wiper sections comprise the two bars 116 and 117, which are crossed similar to a. pair of shears, and supported by a single pivot 118 which may be sustained from a carrier such as that indicated by the numeral 74, in Fig. 2, to be reciprocated horizontally by the slide bar, or by any suitable member having movement to carry the wipers toward and from the shoe. To the rear of the pivotal connection 118 the wiper' bars are provided with slots 120, which receive a pin or roll 122 which is fixed rigidly to a part of the machine frame. When the slide bar is advanced in the operation of the machine the slots 120 will slide over the pin or roll 122 and cause the wiper sections to close together as they are advanced, the construct-ion, as well as the operation of these parts, corresponding somewhat to those of a pair of shears. In this embodiment it is contemplated that the carrier or support for the wiper sections may be adjustably secured to the slide bar as in the preferred construction, and in that case the pin or roll 122 will be adjustably fastened to the stationary part of the frame which supports it.

It is thought that the operation of the several features above described, as well as their advantages, will be apparent without further description. The wiper, as in former machines of this same general character, is so actuated in time relation to the operation of the pincers that when the upper has been seized by the pincers, uplifted to stretch the leather in true conformity with the last, and moved inwardly to lay the upper upon the innersole, the wiper is advanced and wipes smoothly the overlaid stock into its linal lasted position and the driver descends and forces vinto the stock r the tack which was carried forward by the wiper. An especial feature of advantage of the present invention lies in the fact that a single wiper is employed throughout the entire operation, which may be so arranged as to wipe the stock directly over and at right angles to the edge of the sole at those parts of the shoe where by reason of lack of fullness in the leather it is practicable for the pincers to operate without lateral or twisting movements, but which also has capacity for adjustment to wipe the stock in obliquely, and at varying angles and directions to thesole edge, at such parts of the slice, as for instance at the toe, where increased fullness of the stock demands the formation of plaits and the pincers are given the necessary movements to produce such plaits. lt is to be understood, however, that while a wiper which has capacity for adjustment to move in laterally deflected or oblique paths in the manner herein described is useful in the operation of forming plaits or folds in connection with pincers whose movements are such as those described herein, the invention is not in any sense limited to the use of such wiper with pincer mechanism for it will be obvious to those skilled in the art that wipers having such capacities for movement will have many advantages in lasting machines that work the upper into lasted position, without the use of pincers.
