T0 at whom it may concern.-

Be it known that 1, WILLIAM S. MOREY, of Natick, county of Middlesex, State of Massachusetts, have invented an Improvement in Apparatus for Lasting and Trimming Uppers, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts. i

In the ordinary mode of lasting boots and shoes, the upper drawn over the last is plaited or folded upon itself at the toe or end portion, and the surplus materialiucident to the production of said plaits or folds is thereafter removed with a knife to produce an even surface upon which to lay the outer sole. The knife has usually been operated by hand, and considerable time is required to remove the surplus material, and the accuracyof the work done varies more or less.

In accordance with this invention trimming devices are combined with the operating mechanism of a lasting-machine so as to be operated in conjunction with the lasting devices.

The lasting-machine to which my invention is applied comprises wipers or toe-formers adapted to close in the upper upon the end or toe portion of the last, and the trimming or' cutting ofidevices consist of two knives, movable in curved paths or otherwise toward each other and in a plane parallel with the bottom of the last. The cuttingedges of the knives normally lie flush with or back of the forward acting edges of the wipers or toe-formers, so that the latter may act upon the upper in ad Vance of the knives at the beginning of the operation; yet said knives are provided with suitable operating mechanism, whereby they may thereafter be brought forward and move in advance of the wipers or toe-formers. The wipers or toeformers hence first act to-bend or turn the upper over the edge of the last, and thereafter, as they move forward closing in said upper and producing by such operation folds or plaits, the knives are moved forward, advancing ahead of the wipers or toe-formers, and act to trim off the surplus material just ahead of the wipers. Both the wipers or toe-form ers and the knives are connected with theactuating mechanism of the machine, but to enable the knives to start flush with or behind the acting edges of the wipers or toe-formers, and thereafter advance ahead of said wipers or toe-formers, they must be connected to independent carriers or moving devices, and the said independent carriers or moving devices are connected with the actuating mechanism.

I Figure 1 shows in plan view an apparatus for trimming an upper on the last embodying this invention and applied to a well-known form of lasting-machine; Fig. 2, a similar view to Fig. 1 with the parts in another position; Fig. 3, a horizontal section of the apparatus shown in Fig. 1, the boot or shoe being shown in dotted lines; and Figs. 4 and 5, details tobe referred to.

The base-plate a, of any suitable shape, has secured to it at or near its opposite edges two guide-blocks a 0/, against which bear segmental or curved plates 1) b, which serve as operating-levers. Guide-pins 3 3 or equivalents are located at the opposite sides of the operating-levers b b, which, co-operating with the guide-blocks a a, present suitable guides, in which the said levers may be moved. Arranged centrally on the base-plate a, between the operating-levers b b, is a plate or carrier 0, held in position and adapted to slide freely between guide-pins 3 3, said plate being connected with the hand-lever h by a pin hiwhich passes through and moves in a straight slot If in the base-plate. Two links I) b connect the operating-levers Z) Z) with one end of the plate 0. In a horizontal plane just above the plate or carrier 0 and in alignment therewith is a plate or carrier 0', which overlaps the plate or carrier 0 for a short distance, said plate or carrier 0 being connected by links 0 c with the links I) 1), thereby forming toggle-levers. Plates ee are pivoted at e to the plate or carrier 0', which constitute wipers or toe-form ers, said plates 2 6, each having a curved slot or passage 6 6 which receives a pin 6 fixed to the under side of the operatinglevers b b. The operating-levers b b are recessed, as shown by dotted lines, Fig. 1, to form shoulders against which the wipers e e bear. All these parts are substantially the same as in the so-called Chase lasting-machine.

Lugs d d are formed integral with 01' secured to the plate or carrier 0, and the shanks d d of the knives are connected by longitudinally-adjustable links d d to said lugs d d. The knives, preferablyhaving crescentshaped blades (1 d are supported in recesses formed in or passages made through the wipers e e, and are also moved by said wipers in addition to being moved by the plate or carrier c. When the hand-lever his moved in the direction of the arrow shown in Fig. 1 into the position shown in Fig. 2. the plate or carrier 0 is moved longitudinally, and by means of the connecting-links b b the operating-levers I) b are moved, they operating to swing the wipers e e on their pivot e, carry ing the knives with them, and by means of the connecting-links c c the plate or carrier 0' is also moved longitudinally although not for an equal distance or equal rate of speed, and as the wipers are pivoted to the plate or carrier 0' it will be seen that they will be moved bodily in the direction of the movement of the plate or carrier 0, while the knives, being connected to the plate or carrier 0, will be moved in the direction of movement of said plate or carrier in advance of the wipers. Thus it will be seen that by means of the several different directions of movement given to the knives they will efieet a draw out while moving toward each other, and, furthermore, as the knives and wipers are connected to independent carriers orplates the knives, while starting flush with or behind the acting edges of the wipers, may be moved ahead faster or in advance of the wipers.

As a preferable means of adjustment for the links h I have made the same of two separate parts, the abutting faces of which are serrated, as best shown in Figs. 4 and 5, and adapted to be joined bya bolt 4 and nut 5.

A rest .A (see dotted line, Fig. 3) is herein shown as a means of supporting the boot or shoe while being lasted and trimmed. Theboot or shoe (represented by dotted lines, Fig. 8) is placed on the rest and the upperis first turned or bent over the edge of the last by means of the wipers, and thereafter as said wipers advance, drawing the upper down or closing 'it in upon the bottom of the last, the knives advance ahead of the wipers and trim 0d the surplus material produced by the formation of the plaits or folds. The carriers or plates 0 c are independent of each other, in that they are moved at different rates of speed, and consequently unequal distances; yet they are both connected to and operated by the hand-lever or other suitable actuating device or mechanism.

I do not desire to limit my invention to the particular number of knives employed nor to the particular construction of mechanism employed for operating them.

I claim- 1. In an apparatus for lasting boots and shoes, a support for the boot or shoe, two wipers or toe-formers for turning the upper over upon the bottom of the last, and a carrier for said wipers or toe-formers, combined with two knives movable in a plane substantially parallel with the wipers, an independent carrier for said knives, and a single actuating mechanism for the said two carriers, whereby the acting edges of the wipers are first made to automatically act on the upper to lay it over on the bottom of the last and thereafter the edges of the knives are made to automatically travel beyond the acting edges of the wipers and trim off the upper in advance of the acting edges of the wipers, substantially as described.

2. In an apparatus for lasting uppers of boots and shoes, a support for the boot or shoe, and two wipers or toe-formers for closing the upper over upon the end of thelast, combined with two knives, connections between them and the toe-wipers to move the knives toward and from each other in curved paths, first with and thereafter in advance of and in planes substantially parallel with the wipers for trimming off the projecting portions of the plaits just in front of the moving wipers forming them, two independent carriers, one superimposed upon the other, one carrier for the knives and the other for the toe-wipers, and a single actuating mechanism with which both carriers are connected to automatically move them simultaneously and at different speeds, substantially as described.

3. In an apparatus for trimming uppers of boots and shoes on the last, a rest for the boot or shoe, two pivoted wipers for drawing the upper over the last, a longitudinally-movable carrier to which said wipers are pivoted, guides for the wipers to move .them on their pivot, and a single actuating mechanism for moving said wipers andcarrier longitudinally on said guides, combined with two knives and means for moving them independently and in advance of the wipers, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM S. MOREY.
