To all whom it may concern:

Be it known that I, AETHUaCAssL'roN, a subject of-the King of England, residing at Leicester, in the county of Leicester, England, have invented certain. Improvements in LastingMachines, of which the following description, in connection with the accompanying drawings, is a SPGGIfiCMZIOIHdIhEfi reference characters on thedrawing indicating like parts in the several figures.

This invention relates to lasting machines,

and more particularly to a tread engaging member or work rest for use in such machinesfor supportingthe work, or acting ent No. 584,744, but it is tobe understood that it is. not-limited to use with such type of machine.

When the work rest is used in connection with a machine of the type referred to it will be constructed to project into such a position that the insole of the shoe being lasted can be pressed against the rest while the projecting edge of "the upper will be in position to be engaged by the pmcers or grippers.

An object of the invention is to improve the tread rest, in such a manner that it will automatically adapt itself to the surface of the insole and hold it more securely for the operation of the machine notwithstanding that the disposition of the said surface changes somewhat in its horizontal relationship to the machine.

A work rest constructed according to this invention also permits a ready tipping of the shoe to raise or lower the work surface "at" either side of the machine While still maintainin -"the bottom of the last in firm contact with the rest.

The invention can with particular advantage be applied to a lasting machine such for example as that shown in United States Letters Patent No. 1,007,051, granted October31, 1911, which includes mechanism for inserting ,two tacks at each cycle of the pincers operation uponcertain parts of the work, asby its application to such machine Specification of Letters Zatent.

Application filed October 2, 1911. Serial No. 652,270.

equal extent. Accordingly, a feature of the inyention is the provision for a lasting machine of a tread rest or work support that is automatically adjusted by its contact with the work to suit variations in the inclination of the adjacent marginal portion of the shoe bottom.

Gonveniently, the tread rest or work support having the characteristics above set forth may also be arranged to automatically adjust itself in other directions 'by swiveling at right angles to the swiveling motion first mentioned, or otherwise, so as to compensate for angular disposition longitudinally as Well as for lateral displacement out of the horizontal.

invention is therefore, a shoe rest or work Another feature of the support for the purpose described that is 'mounted to, swivel both laterally and in a direction at right angles to the said lateral swiveling movement.

Patented Sept. 1, 1914.

Another feature of the invention comprises for a machine for'l'astin boots and shoes in which there'is capacity for inserting a plurality of fasteners, the combination with a tread face engaging member that is automatically adjusted by its contact with the work to suit variations in the inclina-.

tion of the adjacentmar'ginal portion of the shoe bottom, of connections actuated by the 1 tivel to the adjacent tread surface notwithstan ing variations in the level of that surface.

The invention will now be described as to i one form or embodiment, but it is to be understood that although the constructions described are of a preferred character the invention is not to be regarded as confined to the exact arrangement set forth, but that it may be varied as to the number, form and disposition of the )arts and their method of operation, as welas applied to machines other than that of the particular type shown.

In the drawings: Figure 1 is a side eleva' tion, partly sectional, of suilicient of a lasting machine to enable the tread rest or work support of this invention to be understood, and shows said rest in the position which it occupies when in use; Fig. 2 is an enlarged view in transverse section of the tread rest, on the line 22, Fig. 1; Fig. 3.i-s a plan tread reston a somewhat enlarged scale; Fig. 5 is a view similar to Fig. 1 but showing an operative connection between the tread rest or work support and the fastening-inserting mechanism to control the stroke of the drivers; Fig. 6 is a front elevation of the parts shown in Fig. 5; and Fig. 7 is a horizontal section on the dotted line 77, Fig. 5.

The column 2 of the machine supports the head 4 which is provided with bearings for the usual main shaft carrying cams for effecting the several movements of the lasting instrumentalities. These cams impart to the pincers 5 the closing movement to cause them to seize the edge of the upper, the updrawn movement to lift the upper and stretch it about the last, and the overdraw movement to lay the stretched upper.

upon the insole. The machine may also be equipped with the usual mechanism for imparting the plating movements to the pincers, and with fasteninginserting mechanism comprising adriver, or drivers, tack-- supplying means, such as a raceway, a tackcarrier and tack separator for each. driver,

and actuating mechanism for these several parts. These instrumentalities together with the cams and their connections for imparting the several movements to the pincers are not illustrated herein, as they form no part of the present invention, but all may be substantially as shown and described in the Letters Patent No. 58%744, above referred to.

The tread rest or work support, as illustrated in Figs. 1 to 4, is carried by a bracket 8 supported adjustably, as for example by screws 10 passing through slots in the bracket 8 and entering a projecting portion 12 of the machine head 4-. The. lower part of the bracket, or as shown in'Fig. 1, an arm 14: adjustably secured thereto, has an extended portion 16 that is inclined toward the front of the machine.

The portion 16 comprises a bushing or sleeve 18 which receives a stem 20 to the lower end of which is connected a plate 22.

that forms the part of the tread rest which engages the insole. The plate 22 may be roughened or grooved as indicated at. 24, (Fig. 2), in order to hold the insole securely,

and is further provided with a perforated.

ear or lug 26 adapted to be received between ears 27 forming part of the stem 20, andpivoted thereto by a pin 28. The stem 20 is provided with a flange or collar 30 which rests against one end. of the sleeve 18, the stem being prevented from movement along the sleeve in the opposite direction by a collar 32 secured to the stem by a pin 34:. The said pin may be made of such a length that a portion will project beyond the collar 32 at one orv both ends so as to form a-stop to limit the turning movement of the stem in the sleeve in one or both directions by the engagement of the projecting part or parts of the pin with the arm 1-1. There may be secured to the projecting portion 16 of the arm 14:, as by a screw 17, a leaf spring 35 with its free end bearing on the cars 27 and thereby tending'to hold the plate 9.2 in a substantially horizontal position.

From the foregoing it-will be seen that the connection of the work-engaging plate with the stem 20 through the pin 28 passing through the lug 26 and ears 27 forms a pivot about which the plate-22 can swivel in one plane, while the connection of the stem 20 with the sleeve 18 forms a second pivot about which said plate can also be swiveled in a direction at right angles to the direction of the first swiveling movement. Obviously a modification of the foregoing is one wherein instead of the work engaging plate 22 turning about two independent pivots a universal connection, such as a ball and socket joint, could be provided between the work-engaging plate and its supporting bracket.

In Figs. 5, (3 and '7 a two tack lasting machine of the type shown in Patent No. 1,007,051 above referred to, is illustrated in which a tread rest or work support, similar to that described in connection with Figs. 1 to 4, is included the said rest being connected with fastening-inserting mechanism in such a manner that the stroke of the independent nail drivers will be changed in accordance with changes in the level of the marginal portion of the shoe bottom at the points where the two tacks are driven, as for example when the margin of the shoe is elevated at one side and the rest swiveled out of the horizontal. As illustrated in the drawings these connections comprise ashaft 36 which is carried in a sleeve 38 extending upward from the bracket 81 The shaft 36 carries at its lower end a crown gear wheel 40 which meshes with another crown gear wheel 42 secured on the stem 20 carrying the work-engaging plate 22. At the upper end of the shaft 36 is a bell crank 4.4, the free end of each arm of which is loosely connected by a linkdG with an arm 48 of an abutment 50 against which a collar 53 on each driver bar 51 abuts in its nail-driving stroke. Each abutment is made in two parts the lower 50 of which is stationary and is provided with a cam or wedge surface 54.- agamst which bears a corresponding cam or wedge surface .55 on the upper and rotatable part 50 of the abutment.

It will be seen that the inclined surfaces are disposed oppositely .to one another so that as the bell crank 44' is turned with the shaft 36 in one or the other direction the the abutments in their adjusted positions a wedge 58 is located between the adjacent edges of the abutment members 50 in such a manner as to be capable of sliding movements. The forward portion of this wedge carries a stem which slides in an opening in a casing 56, and a spring 59- surrounds the stem and is compressed between the casing and a collar on the stem. This. spring acts with a normal tendency to force the wedge into gripping engagement with the rotary abutment members so as to lock them against rotation. The wedge is held out of action while the drivers 51 are raised by a lever 60 pivoted at 62 to an extension of the head 4, the said lever being acted upon by a cam surface 64 carried by one of the driver bars 51. When, therefore,'as'illustrated in Fig. 5, the driver bars occupy an elevated position an anti-friction roll carried by the upper arm of the lever 60 is engaged by the cam surface 64 which causes an outward movement of the lower arm of.

said lever and moves the wedge 58 out wardly, compressing the sring59 and disengaging the wedge from t e rotatable abutment members 50 50 which are thereby rendered free to be ad usted by the movements of the work rest.

Bythe provision-of the operative connection asabove set forth between the rest and the fastening-inserting mechanism the height of the abutments 50 which limit the extent of the down stroke of the independent drivers will be altered according to the extent of the displacement of either side of the work-engaging plate 22 and the two tacks can each be inserted to a predetermined level relatively to the adjacent tread surface notwithstanding variations in the level of that surface.

In the use of a lasting machine rovided with the devices as above descri' and illustrated in Figs. 5, 6 and 7, the pincers are given their usual movements in order sole pressed against the plate 22 of the work rest, which acts as an abutment to resist upward movement of the shoe against the force of the updraw of he pincer, the trans versely arranged pivo 28 permitting the plate to rock so as to conform to varying the shoe bottom, and the swivcled stem 20 the margin of the shoe bottom. l hlring these latter adjustments of the plate through the described connections the driver bar abutments are caused to control the distance traveled by the drivers in accordance with the varying levels of that portion oi? the shoe in which the fastcnings are to be inserted. so that sad fastenings will always be driven equal distances into the stock.
