LASTING-MACHINE Specification of Letters Patent.

Patented July 14, 1908.

Application filed April 3, 1899. Serial No. 711.477.

To all whom it may concern:

Be it known that I, GEORGE W. CARTER, a citizen of the United States of America, residing at Haverhill, in the county of Essex and Commonwealth of Massachusetts, have invented certain Improvements in Lasting- Maohines, of which the following, read in connection with the accompanying drawings, is a specification. 1

This inventionrelates to machines for use in the manufacture of boots and shoes and more particularly to machines adapted to be employed in conforming an upper to a last.

An object of this invention is to provide means by which the portion of the upper material that is turned over upon the bottom of the shoe may be conformed to the shape of the last and made ready for the rece tion of the outer-sole better and'more rapid y than has heretofore been done.

To this end a broad feature of this invention consists in providing means for pounding down the shoe stock on the bottom of a last to compact the upper materialsagainst the innersole and to flatten down the wrinkles or folds which are es ecially prominent at the toe and heel of t eshoe. ,In the embodlment herein shown a pounder is opera tively connected with actuating mechanism by which it is moved over the shoe bottom inwardly from the edge of the shoe and downwardly toward or against the shoe bottom. In the machine illustrated the poundtool advances over the shoe bottom in 1H ru bbingcontact with the up or so that it forces it mwardly from the e go of the shoe to and beyond the usual tacking line and is then actuated downwardly at an angle to its] .inward movement for flattening the upper against the innersole.

Another very important feature of this invention consists in the combination of means for working the upper over the last with means for pounding the overworked u per. In the embodiment of the invention s own herein the pounding means is applied to a lasting mac ine of the type shown in United States Letters Patent No. 584,744 and operates in time relation with means for pulling the upper and crimping it-at times to conform it to the last and with means for securing the upper, all of which may be, the same as' the means shown for the same purposes in said Letters Patent.

Im ortant features of the invention are also 'ound in the combination. of grippers for pulling and overlaying the upper with means for pounding the upper and in the combination of the pounding means with means for driving fastenings to secure the upper. =The illustrated machine performs the'lasting and pounding operation step by step by re eated operations upon successive portions 0 the shoe.

These and other features of the invention, including certain combinations of parts and details of construction, will be explained in the following description of the machine and will be pointed out in the claims.

Of the drawings, Figure 1 is an elevation showing one side of the machine embodying this invention; Fig. 2 is a perspective showing detail referred to hereinafter. Fig. 3is an elevation, partly in section, showing operative parts of the machine, including this invention. Fig. 4 is a view similar to Fig. 3, showing the parts in different positions of operation. Fig. 5 is an elevation of a section on line 5 of Fig. 8. Fig. 6 is a plan of the pounder member detached. Fig. 7 is a perspective showing a modified form of the pounder and a section of the actuating member. Fig. 8 is a plan of the pounder shown in Fig. 7. on line 9 of Fig. 8. r Fig. 10 is a side elevation of the pounder shown in Fig. 8.

- It may be here remarked that the machine comprises a single pair of pincers and actuating connections (for more specific description whereof see United States Patent 584,744)

whereby the pincers are made to grasp and strain the upper over the inne'rsole, the lasting operationlbeing. carried out as a whole by repeated oper'ations'of the pincers applied to different parts of the upper at different times. After. the section of upper is overlaid upon the innersole it requires to be fastened thereto and in this connection is employed a tackholder, shown in the present instance as comprising the members 2, 3, shown detached in Fig. 2, which are journaled in the pounder member 4, for closing together directly below the tack receiving channel 5. Springs 6 operate for normally holding the members in closed position, thereby stolpping'downward progress oftack 7, and yie d for passage of the -tack between said members in the driv ing, operation. For a further description of .150 maden oreuniformlysmooth, thus dispensing said parts reference may be nadto United States Patent 584,744. The trick, it'will be understood, requires to be'carried in said holder from the point where it is discharged 1 into the holder to the driving point, and, to this end the pounder member. 4, whereinthe holder'is constructed, has connection with art 8 whereto movement forwardly and backwardly is given by actuatingmechanism more fully shown and described in United States Patent above referred to. Connected with the member 4 is "a smoothlypolished part I 9, which inthe forward movement of said part United States Patent No. 441,482 ,and comprises a torsional spring rod 20 mounted in a tubular casing 21 carried by the frame, said rod being fastened at one end to the. casing and carrying at its other end an arm which is connected to the link 15. The bar 14 is lifted against the tension of thespring-rod 20 by means of a cam, and whensaid cam moves out of engagement with said bar the spring rod 20 o erates to depress 'said' bar to drive a tack. nder'the arrangement of the present machine the work of pounding and flattening 'the upper is carried on simultaneously with the'tack driving operation. To this end the pounder block or'member 4 has its rear end pivotally-connected with the part 8, thereby adapting its foremost end for movement I downwardly, and the bar 14' which carries thehammer-rod 10 is positioned so that, 'in

' descendin to drive the tack, and just before reachingt e limit of its throw downwardly,

it will strikeupon the pounder member 4 and drive itLdownwardly upon the overturned material located thereunder whereby the said material from the edge of the shoe bottom't'o a 'p'o'int beyond the tacking'line is set, and

ribs or' folds therein,'-if-any, are crushed and flattened down upon'the ,innersole and the surface for receiving the outer-sole is thereby withb'r rendering less essential the operation of subsequently pounding down or trimming off the rldge that is formed by these-folds;

The pounder member 4 is formed with a'cam j lift 16, which, in the backward. movement thereof from over the shoe bottom, will engage the end of the shoe-edge resting mem-' ber 18 of them'achine and lift the pounder member to the altitude required for its next I movement forwardly over the'shoe bottom.

For a full'd escription' of the said shoe-edge restlng member see United States Letters- Patent No. 562,119.

.the shoe and is -with the descending hammer-bar 14, where- 80 In Figs. 7, 8, 9, and 10 of the drawingsI (see Fig. 9) and is capable of movement vertically in the said socket or chamber. It also has the incline or cam lift 44 to engage the shoe-edgenresting member of the ma-' chine, whereby said member 42 -is lifted preparatory for the movement forwardly over positioned for engagement by to be driven downwardly u on the'overturned upper material locate thereunder, all substantially as described before.

In the foregoing descriptionand in some of the claims the term pounder is employed as the name for the tool that is used to operate upon the shoe stock for forcin it into position upon the shoe bottom. he term is used for convenience asa name forthe tool without any intention of implying thereby any limitation as to the nature of the tool.
