Specification of Letters Patent.

1912. Serial No. 699,202.

To all who: it may concern:

Be it known that I. An'rirnn Barns, a subject of the King of England, residing at Leicester, Leicestershire, England, have in vented 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 type dis- 58 lf4l4c, dated June 15, .1897. In the machine of said Letters Patent the upper is worked into lasted position by devices not ing 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 pincer-s and wipes or presses the overlaid upper material smoothly upon the solo. 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 at 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 and 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.

in the herein described embodiment of the invention the wiper comprises two members that are arranged for simultaneous movement toward and from the shoe. in a direction which may be normal to a curved edge of a shoe, along convergent paths that are inclined to the median line of the machine, so as to wipe the upper inwardly from the edge of the sole, and at the same time in opposite directions along or subslmitially parallel with said edge. The wiper members are preferably crossed, as shown, and are pivoted at an intermediate point to their carrier, and have their rear portions provided with guiding slots which are entered by a pin or projection rigid with the frame of the machine. \Vhen the carrier moves inwardly toward the shoe and advances the wiper members over the edge of the sole the movement of the pin or proection 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 movement of the wipers is elfectecl by the same means.

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

This application is a division of my Patent No. 1,029,841), granted June 18. 1912, in which the generic claims are made covering 'lnroadly the construction herein illustrated.

In the drawings, Figure l is a perspeolive view of the principal operative parts of a lasting machine with an embodiment of the present invention applied thereto, the supporting pedestal and frame being omitted; Fig. 2 is an exploded view, show mg in perspective the wiper and its actuating devices. Fig. 3 is a plan view of the. wiper.

The main shaft l. of the machine which turns in suitable hearings in the frame, carries a cam block 2 which provided with a cam groove or way to receive a roll on a slide t which is connected at its upper end to a rocking lever This lever is ful- (u-uincd at (i, 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 jaw 10. The other pincer jaw 12 is connected to a rod let that extends upwardly tl'u'ougli the sleeve 8 and is engaged at its upper end by a spring-pressed plunger 16 in a lever 18. The lever 18 is 'lulcrunied 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 in its 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 a cross head 36 by means of which the pincers are caused to move or swing laterally. A link 37 con nects the cross head 36 r with a lever 39 which is fulcrumed through an 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 movements of the pincers simultaneously with the lateral movements of the pincers informing the plaits or folds, said parts being fully shown and described in Letters Patent No. 584,744 heretofore referred to. The cross head36 is sup portedin 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 which is guided in a boss 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 having the usual operating mechanism including a knee lever as shown. Thebell-crank lever 46 is fulcrumed at to the main frame, and is shown as having one arm formed as 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 shaft 55 is connected at its, front tion and extent of such movements.

The mechanism described above for lowering and raising the pincers, closing them,

and swinging forwardly and backwardly, and for effecting their plaiting movements are fully described in the aforesaid Letters Patent 'No. 584,744, and of themselves form no part of the present invention. In the operation of these parts it is deemed suflicient to explain that the pincers with the jaws open are lowered bythe 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. lVhenthe knee lever is set to adjust the block in an eccentric position in the rocker 32 the pincers receive also lateral and twisting movements for plaiting 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 1. The lower end of the lever 66 is connected with a slide bar 7 2 which is suitably guided for horizontal movementin 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.

In operation, the slide bar isrecipr'ocated to carry the wiper back and forth by the cam 70, and when it reaches a suitable position inits rearward movement a tack is defrom 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 wipe 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 by screws 76 a wiper carrier or support. 74 Fig. 2. The carrier 74 is shown as having a tacloreceiving aperture 78, 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 parts of the wiper are pivotally supported at a point between their ends. The wiper members are shown as having notches in their inclosed position, and is therefore in longitudinal alinement with the carrier.

As herein shown 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 the single pivot 80 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 80 the wiper bars are provided with slots 120, which re ceive a pin or roll 122 which is fixed rigidly to a part of the machine frame. \Vhcn 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 construction, as well as the operation of these parts, correspomling somewhat to those of a pair of shears. The carrier or support for the wiper sections may be adj ustably secured to the slide bar, and in that case the pin or roll 122 will be adjustably fastened to the stationary part of the frame which supports it.

While the parts of the wiper are deflected outwardly from the longitudinal central line of the machine when retracted, it is neces sary that at its most advanced position the wiper should present its tack-receiving aperture 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 slots 120 are inclined relatively to the center line of the machine and extend inwardly and toward the rear. The inclination of these slots to each other will therefore be greatest when a the wiper is in its extreme rear position, and

as the. two-part wiper advances toward the shoe the lateral deflection or inclination of its parts will decrease gradually as the roll 122 iLPPI'OiU'fllQS the outer end of the slots 120. Said roll being in line with the central line of the machine, the wiper will, as a whole, occupy a central position where its aperture S-il is in alinement with the aperture 78 and also with the driver 79.

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 pincers have seized the upper, uplifted to stretchthe leather, and moved inwardly to lay the upper upon the inner-sole, the wiper is advanced and wipes smoothly the overlaid stock into its final lasted position and in accordance with this invention the wiping movements take place along convergent paths directed toward the driver which descends and forces into the stock the tack which vas carried forward by the wiper. It is to be understood, however, that while the herein described wiper 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 that produces plaiting movements, nor in fact with any pincer member, 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.
