Specification of Letters Patent.

Patented June 5, 1917.

Application filed September 17,1915. Serial No. 51,191.

To all whom it may concern:

Be it known that I, ALBERT A. MAoLEoD, a citizen of the United States, residing at Swampscott, in the county of Essex and State of Massachusetts, have invented certain Improvements in VVork-Supports, 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 work supports and particularly to work supports adapted for use in connection with fastening inserting machines. The invention is herein illustrated as embodied in a machine for lasting stitch-down shoes of the general type disclosed and claimed in United States Letters Patent No. 1,117 ,087 granted November 10, 1914, on an application of Adam H. Prenzel.

Machines of the type disclosed in said Letters Patent are adapted to wipe successive portions of a shoe upper down the side faces of a last and tuck the upper into the angle between the last and the sole margin, in which position the upper while under tension is secured exactly in final lasted position by permanent lastingfastenings which are inserted through the angle of the upper into the sole. In certain classes of work it is advantageous and desirable that the fastenings be located and clenched in a slit in the sole, the fastenings being driven through the angle of the upper and into one of the two parts into which the sole is divided by the slit. Machines of the type disclosed in said Letters Patent as heretofore constructed have not been adapted for inserting the lasting fastenings in a slit in the sole principally because there has been no provision in the work supporting parts of such machines for properly positioning the outer of the sole shoes the soles of which are slit for the reception of the lasting fastenings.

In accordance with this object of the invention, novel shoe supporting means are herein shown and described in which the staple clenching element or anvil is offset and spaced from a shoe sole engaging face, the anvil being constructed and arranged to enter a slit in the sole of the shoe to be operated noon to clench fastenings driven in said slit into one of the two sole parts into which the sole is divided by the slit, and at the same time to provide a recess between the anvil and the sole engaging face for the reception of the other of said sole parts. By the use of the illustrated construction and arrangement, not only are the'fastenings driven through one of the sole parts into which the sole is divided by the slit and properly clenched in the slit, but breaking down, marring or otherwise injuring the other of said sole parts is entirely prevented so that this part of the sole may be properly laid and the slit closed after the upper securing operations have been completed.

The embodiment of the invention herein shown and described is illustrated in its application to shoes the soles of which are provided with oblique slits starting at a point somewhat removed from the point of intersection of the edge and top faces of the sole, soles provided with such slits being commonly known in the trade as McKay chan neled sol-es, and the lower of the two sole parts into which the sole is divided by the slit or channel being commonly termed the channel flap or lip. Purely for convenience, the slit in the sole and the lower of the two parts into which the sole is divided by the slit are frequently referred to hereinafter respectively asa channel and a channel flap. It is to be understood, however, that this showing and description are not intended to limit the invention since it is appreciated that the invention is applicable to use in connection with soles provided with slits diifering in direction from the showing in the appended drawings or located farther from or nearer to the tread face of the sole than the slit illustrated in the drawings, and the terms channel and channel flap wherever used herein are to understood as used generically and, ac- I cordingly, are to be so; construed.

These and other "features and objects'of the'invention will be apparent from the following detailed; description read in connection [with the accompanying drawings I and thevarious novel features of the invention. will be set forth in the appended claims. In the drawings Figure 1 isa front elevation of a portion of theju'pper part of the machine;

, The illustrated machine in which a prefl Fig; 3 is a perspective view of theshoe 4, ferred embodiment of the invention is here- 7 United granted vFebruary 13, 1912, on an application of WilliamH. Borden, except that the parts tially U o inshown as incorporated comprises staple forming and inserting mechanism substanlike that shown and described in States Letters Patent No. 1,016,930,

are fitted to operate upon'much finer wire than is ord narily used in machines of this type. "This mechanism is mounted in'a head i 2 carried upona standard 4 and the formed o angle between the side faces of :the last and staplejis driven through a staple guiding throat inja" member 6 which also acts as a lasting tool to wipe the shoe upper down the side faces of the last and tuck, it into the the projecting sole margin.

1 As shown,the work support upon which i theshoeis supported during the lasting op erationis movabletoward the lasting tool formed upon a segmental block 10 which is I in the block 141 about an axis lying in a plane I corresponding. to the work engagingend of the lasting tool 6 when it isin its operative ,,position and it is clamped in its di'fl'erent poto efi'ectthe upper stretching and wiping operation by means of a suitable foot treadle (not shown), as in the machine shown in Letters Patent No. 1,117,087. The; sole supporting face of the work support is provided with curved flanges 12 that are received in, correspondmg grooves in a SGgHIQIltQLllOlOC/k 10 is guided for adjustment 'sitions of angular adjustment in the split blo'ckby' theclamping'screw 16. In order, Y that the'block 14 may be adjusted in a horizontal plane toward and away from the lasting tool to bring its staple clenching surface into'aline nent' with the'staplepassage in the member 6, the block 14- is carried by a split block 18 provided with dovetailed guideways in which is received the dove-tail Ton thelower part of the block 1%, the block 14 being clainpedin its different positions of horizontal ad'ustment b the clam Jin nuts v l a 24, oneof which provides a connection for one end of a spr ng 26 which tends to ma1nsition, the othergend, of the spring being setain the work support in its inoperative po -l cured to a part of the machine, frame. The

blo'clr 18 is mounted upon a rod 28 guided for vertical movement through a treadle connection (not shown) in guideways 30 at ta'che'd to the machinev frame.

In the illustrated construction the segment anvil 34: spaced from the sole engaging face tal shoe supporting block 10 comprises a sole f engaging face 29 and a fastening clench ng 29,the block 10 being so positioned relatively to theb'lock 14 that the s'ole engaging face 29, is substantially parallel to" the bottom workengaging face of the lasting tool 6;

; The offset fastening clenching anvil 1s construotedand arranged" to enter a slit in,

to present a'staple clenching surface in ithe line of drive of the staple, shown this anvil is' lformed upon a [cylin drical plug 36' of harder materialthan the block 10 and is inserted in the sole support ing face of the block 10, the plug being held the sole of shoe to beoperated 'uponto clenchi fastenmgs and tis so arranged as ,As herein I against rotation in the block by pins 38.,

The fastening clenching anvil 34, as illus trated, projects at an angle above the in- I clined surface 32 and transversely of the block to provide a surface at substantially right angles to the line of drive of the fas-' teninginserting mechanism and has its outer I I ,verticalface cupped to provide clenching cavities d0 to facilitate controlling the direction of clench of the, legs of thestaple, as shown in FigQ, the legs of the staple being is less possibility of their being in the way during the later sewing operations. The space beneath the overhanging portion of the anvil 34c and which extends beyond its preferably clenched inwardly so that there c outer end is cut away :as at L2 to adapt it to I receive thelower of the, two so'le Iparts'into which the, sole is divided by the slit to preventthe flap from being broken down or injured by the clamping pressure between t I the lasting tool and thework support dur- I ing' the lasting and fastening inserting op-,,

erations. shaped, particularly with reference toqthe clenching anvil to enter the channel readily and in a position which will permit the staple to be clenched in the bottom of the, channel.

'7 In the use of the Worksupport herein de I The walls of this recess 42 are olfsetS i, so that it opens up the slit or channel in the'sole and" enables the offsetstaple scribed, the anvil 34: enters the channelyin the sole,'the leaf of the slit being received in the recessed portion 42 of the sole supporting block 10 and theprojecting margin of the sole being supported upon the inclined V sole supporting face 32 of the block 10. c

Movements of the work support with, the

shoe thereon into position for the shoe to receive a fastening causes the projecting margin of the sole and the outturned portion of the upper to be clamped between the lasting tool 6 and the inclined face 82 of the sole supporting block 10, in which position the anvil 34 will present its clenching cavities LO in the line of drive of the staple through the tool 6. It will be noted that since the leaf or channel flap is located in the recess 42 in the block 10 it is protected from being injured during the successive fastening inserting operations of the machine.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
