LASTING-MACHINE.

the direction of the length of the last and at" the same time swing inwardly in opposite directions crosswise of the last.

The invention consists in the improvements which -I will now proceed to describe'and claim.

same parts in all of the figures.

In the drawings, 1) represents a base or support for the wiper-carrier b the wipers b, and the wiper-operating mechanism hereinafter described. The base or support Z) is preferably pivotally connected with a fixed bed a, so that the path of movement of the wipers may be varied to suit either right or left lasts. This feature, however, is not a part of my invention.

The base or support I) is provided with I guides 17 12 between which is fitted the slide or carrier 5 with which the toe-wipers b b are connected. The said wipers have segmental ribs b b engaged with segmental slots in the carrier b said ribs and slots causing the wipers to swing in circular arcs when the wipers are pressed forward.

17 6 represent sliding racks fitted to move in guides on the base I) and meshing with pinions b 12 which are provided with studs 12 fitted to rotate in bearings formed in the carrier b Said racks are connected by links Z9 with the wipers Z). The pinions Z9 mesh with a sliding rack Z2 which has a screwthreaded socket meshing with a screw b which is j ournaled in a bearing 1) on the base I) and has a hand wheel I). Then the screw b is rotated, it causes an adjustment of the wiper-plates toward or from each other, as hereinafter explained. When the carrier 12 is moved endwise by the lever b (the rack b remaining stationary,) the pinions b ,mov-

ing forward with the carrier, roll on said stationary rack and impart an accelerated forward movement to the racks 5 this motion being due to the bodily movement of the pinions 17 with the carrier 19 and to the rotation of the pinions on their own axes caused by their engagement with the rack 11 This motion is imparted to the wipers b by the links Z7 the wipers being thus caused to move forward with the carrier and to swing inwardly toward each other, the segmental ribs 17 moving in the segmental slots of the carrier, constituting pivotal connections between the carrier and wipers.

The described forward and inward movements of the wipers cause them to properly wipe the upper over upon the bottom of the last, the toe portion being wiped backwardly or lengthwise of the last, while the side portions are wiped inwardly or crosswise of the last.

It will be seen that the adj ustability of the rack b by means of the screw Z2 enables the operator to adjust the wipers by swinging them toward or from each other before moving them forward by advancing the carrier b The wipers may be thus adjusted to lasts of different widths and shapes and may be caused to swing inward over the bottom of the last to any desired extent. The screw 5 holds the rack W at the desired adjustment, and when the carrier 1) is moved forward the wipers are swung inwardly from the point to which they were adjusted by the said rack and screw. I have therefore provided means for adjusting the wipers toward and from each other before giving them the combined forward and inward movement which wipes the upper over upon the last.

The segmental ribs b on the wipers and the segmental slot in the carrier b receiving and guiding said ribs, may be termed interlocked parts or guiding members,constituting a pivotal connection between the wipers and carrier, said connection being strong and effective. The relative positions of said members may be reversed, the wipers being provided with segmental slots and the carrier with a segmental rib.

It is obvious that the above-described improvements may be used in connection with wipers formed to wipe over the heel portion of an upper. The carrier-operating lever 12 is pivoted at b to the wiper-carrier b and is engaged with the adjustable bed I) by means of a pin'b and a slot b It will be seen by reference to Fig. 3 that the inner ends of the operative edges of the wipers meet at the center on which the wipers oscillate. The object of this arrangement is to prevent any opening between the inner ends of the wipers into which the upperleather may be inserted. By thus excluding the leather from between the inner ends of the wipers I prevent any liability of cutting or marring the leather, which liability would exist if an opportunity were presented for the leather to find its way between the inner ends of the wipers. I also obtain a practically-continuous wiping edge acting alike on the center of the toe of the upper and on the side portions.

I claim- 1. In a lasting-machine, a toe or heel lastaccelerated motion and wiper-adjusting devices cooperating with said mechanism, said devices being independent of the carrier-moving devices.

2. In a lasting-machine, a toe or heel lasting mechanism comprising a base or support, a carrier movable thereon, wipers pivotally connected with the carrier, pinions engaged with the carrier to move bodily therewith, an adjustable rack mounted on the base between the pinions and meshing therewith, and connections between the pinions and wipers whereby motion is imparted to the wipers.

3. In a lasting-machine, a toe or heel lasting mechanism comprising a base or support, a carrier movable thereon, wipers pivotally connected with the carrier, pinions engaged with the carrier to move bodily therewith, a rack secured to the base, and meshing with the pinions, sliding racks meshing with the pinions, and links connecting said racks with the wipers.

l. In a lasting-machine, a toe or heel lasting mechanism comprising a base or support, acarrier movable thereon, wipers pivotally connected with the carrier, pinions engaged with the carrier to move bodily therewith, a rack secured to the base, and meshing with the pinions, means for adjusting and positively holding said rack, and connections between the pinions and wipers whereby motion is imparted to the wipers.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses, this 7th day of November, A. D. 1896.

ARTHUR \V. EATON.
