In the manu acture of boots and shoes,

4 particularly in the manufact-ure of what are known as welt shoes it has become common to employ insoles made 'from a low grade or light leather reinforced by a fabric to. furnish the necessary strength, particularly at the bases vof the lips through which the inseam stitches are formed. In the making of a reinforced .sole of this type, the leather sole that is to be reinforced is usually channeled and the vchannel lip turned or set in an upturned and usually nearly vertical position before ,the reinforcing fabric is applied thereto. My resent'invention has no reference to the ormation of this leather sole, nor t-o the upturningk or setting of the channel lip i thereon, all of which are supposed to have A,been performed prior to that step in thel 30l manufacture of the reinforced sole at which my present invention is intended to become available. The reinforced fabric is ordinarilyf first laid upon the channel side of the leather sole by hand and my present inventionl relates to a machine for'receiving the solI with the fabric thus roughl or approximately positioned thereon, an tucking or working the fabricA into the channel and close to and upon the reviously turned or set li thereof, particularly inthe vicinity of th1s base.

The various features comprising my invention will be best understoodv from a description of one embodiment thereof, which has been selected for the ypurpose of illustration.

In the embodiment of my invention selected for disclosure herein and shown in the drawings, referring first to Fig. 1, the column 1 carries a suitable head 2, provided at its left hand endor front, with vertical ways for the work supporting slide 3, shown in dotted lines. This slide has bearings for the work supportingshaft 4, carrying at its outer end the work supporting wheel work supporting slide is supported from beneath by a spring 6, which bears against said slide at vitsupper end and at its lower end is seated upon an adjusting screw 7, tapped into a `lug 8, on the column. This screw is made tub'ularto receive the treadle rod 9, which extends upward through said spring and is jointed` at its upper end to the'bottom The Y sol of the work supporting slide. This rod and its attached treadle or operating device (not shown) furnish means for. depressing the work'supportlng wheel 5, for introduction of the work, said spring thereafter lifting said wheel and its work to hold the latter firmly 1n position. v

The Work supporting shaft 4 at its inner end is operated by a connection 10, of any desired construction that will permit said sha ft to be moved vertically by and with the work supporting wheel, without losing its operative connection with the driving shaft 11,

centric rod 14, the eccentric of which'is fast uponthe main shaft 15, of themachine and journaledfin the machine head above said driving'shaft' 11. Rotation ofsaid' main shaft operates through said eccentric to oscillate the clutch 12, to impart by said clutch,

a' stepl by stepfrotation to the work supporting s aft and its wheel, always in one direction.. The extent-of each step movement of the work supporting wheel may be. varied loo insole clamped at its margin between the said work supporting and presser wheels, "will rcceivea rapid step by step feed to cause it to progress through the machine to Abe operated upon, as will be described.

Referring to Fig. 6, the insole Sis shown in position clamped between the work supporting the presser Wheels, the latter furnishing a continuous marginal clamp for the sole outside the lip L. This lip has been g5 previously turned and set in a manner well understood by those skilled in the art and by any well-known lip4 turning andsettingmw.

chine. The reinforcing fabric R previously cemented at its under side, has been` applied se manually and approximately tothe lipped face of the insole which also may have been previously cemented, if desired. In applyingthe fabric by hand, it is diiiicult to lay the same down into the bottom of the channel and against the inner face of the upturned and set lip except by the exercise of such time and care as would prohibit the use of said soles. The machine containing my invention is intended to receive the work 4o as shown in Fig. 6 and to lay or tuck the vmaterial within the upturned and set lip down to the bottom of the channel, as `indicated in Fig. 7. Tol accomplish this, I em-` ploy a tucking tool, .herein marked 20, and

so' mount and move it as to cause it to lay the material downl along and upon thebottom of the channel to the bottom thereof and also against the inner upturned face of theset lip. This tool is not a lip setting tool, its purpose being to lay or pushl the reinforcing fabric against and into adhering' contact with the inner face of the turned and set lip. To this end, said tucking tool, see Fig. l, is adjustably mounted in the lower 55. end of `a lever 21, suitably fulcrumed, as at 22, yon theI head of the machine, andactuated at its rear end by an eccentric-rod 23, whose eccentric is fastened uponI and operated by,y themain shaft 15. This eccentric operates 'to impart to said tuck'ing tool a 'rapid inl and out or tucking motion, suchv as will catch .the material lying, for example,

inthe position Fig. 6 and tuck it snugly int'o the bottom of the channel, as indicated in F ig. 7.

The' described conv The shapes of shoesoles are frequently such, particularly when yfor use in the manufacture of womens'shoes, that little'widthof sole is'left between the channelsl along .the shanks vof the soles. The channel isusually '70 cut of uniform width throughout, and if the shank ofthe sole is very narrow, the channel cuts away so muehof the width thereof and" at each side thereof, as to leave .little if any uncut surface between the saine. This makes it important to have the' reinforcing material pressed into firm contact with the face or surface of the sole next adjacent the inner edge of the channel for, if this b enot done in a narrow shank such as above're- S0 ferred to, there would be nothing to prevent the tuckingaction in the channel at one sidethe sole, or the welt sewing machine in drawing and setting4 the stitches in the channel at` one side the sole, from exertingl by itsl action upon the` reinforcing :fabric asufiicient pull to drag the entire reinforcing covering across the sole and out from position relative to the channel onthe opposite side thereof. While this action is less material in the `wider or ball positions of the sole, nevertheless itl is desirable at all points that themateria'l be closely laid upon "the face of the sole next the inner edge of -the channel, otherwise the vneedle of the welt sewing machine. is likely to pass under the fabric and pick it up and lift it4 away from the sole instead of lpenetrating and passing through it, as it should for the best results. For the purpose of thus laying-the fabric closely upon the sole along the inner channel line, as stated, my invention contemplates the use of a hammer 24, best shown-'in Figs. l and 2, and also in diagram, iFig. 7, which is mounted for vertical reciprocation in the head in such posi- .10a tion that, as the sole is` fed through the machine, sald hammer may be reciprocated to .ca-use it to deliver a rapid succession of hammer blows upon' the fabric just within the channel to insure proper adhesive contant of the samevwith the sole beneath. This hammer may be operated in suitable manner-and the sharper theblowitis made to deliver, the better will be `the adhesion resulting therefrom. In the present instance, such 11:3 hammer is connected by a. link'25, see Fig. 1, with alever`26, fulcrumed at 22 and operated by an eccentric rod 27, from another eccentric upon the'main shaft 15. I have herein used an eccentric becausev of its easy motion, but a rcam may be employed instead7 if'desired.

I am able to use a hammer blow or action at the, point described upon the sole, be causedthe sole is otherwise and continuously 12'3 clamped in position for feeding soles to resist any tendency to transverse dislocation by the tucking action of the tool 20; in fact, I prefer, for other reasons, that the hammer be not' so constructed and operated as "to 130 -In thev interval between the 'approximate' positioning of the fabric on the leather sole and the presentation of such material and sole to the machine involving my invention, the loose marginal portion of the fabric has opportunity to `fall and is frequently pressed by stacking, y lip and becomes more or less firmly adhered to such lip.' For they best work this false adhesion or contact should be freed before the tuckingltcol is ,permitted Vto .act edectively. To `this end I haveprovided what for convenience may be calleda lip clearer, marked the samcbeing shapedand adjustably'positionedl to travel along close to the inner face-of the lip and clear it or lfree it of any 'adhesive contactof the fabric therewith in 'advance of the point at Vwhich the tucking tool acts. Thisleaves the tuckingl tool-free to place the material 'with the best possible results." I

T he reinforcing material is usually died out toan approximateshape only, which renders it necessary to trim the margin thereof that p'rojects above and beyond the sole lip after the reinforcement has been completed. Of course, the reinforcing material may be died out accurately and in such event, ifaccurately laid, no subsequent trimming would be required. For the purpose of trimming any projecting margin of such material, I have herein provided trimming means as follows: The clamping wheel 1G (see Fig. 5) is cupped at its front to provide a cutting edge 30, which is continued around its periphery, and, cooperating with its cutting edge. is an oscillatory or vibratory cutter 3l, see Fig. l, also Fig. 5, adjustably clamped upon the end of a cutter shaft 3Q, horizontally mounted in the machine head. At its upper end said cutter shaft. carries a-pinion 33, driven by a segmental gear 3ft, see Fig. l, fulcrumetl at its vrear end in the machine head at 35, and

driven -intermediate its fulcrumed and toothed ends by an eccentric rod 36 from a third eccentric on the main shaft. This construction is such that as fast as the tuck and reinforced sole is fed past the tucking tool,

-the rapid operations of the trimming knife 31, cooperating with thecutting edge lon the clamping wheel, will trim off the projecting edge 'of thel reinforcing material on a line substantially coincident with the crown of the upturned 11p. Because the` clamping wheel is constantly in rotation, a new cutinto contact with thev it ultimately occupying avposition ting edge is constantly presented for coperation with the cutting Iknife, so that a permanent eilicient cutting action is assured. As thc knife dulls and is sharpened, itmay he set forward by means of its clamp. The

. step by step feeding movement yofthe clamping wheel gives opportunity for'the cutting action between fel-red adjustment of thefmachine, there is nov relative side travel of the cutting knives at the moment of cutting.

It will be observed that the yface of the clamping wheel between the clamping surface and the edge that coperates with the cuttil'lg knife, is concave, so as to free the lipof any back support substantiallyk throughout the width of'its concavity. I havel 'found that the 'set and inherent stability of the lip is of itself sufficient to hold it against the-pressure, of thetucking tool withouttany back support and that the latter, iffprovided, might tend toprevent such conformation of; the lip under the tucking action asf-.wonld'be necessary to enable it to present suitable surface to thefabric when thellatter is pressed against it by the tucking too the feeds, so that in the prevThe active end of the tucking tool may be given any desired shape. to conform tothe shapel orehannel and adjacent basel of the upturnedy lip. .It isnot necessary that the lip be. turned or set to aposition truly perpendicular to the sole; in fact, itis better if it be set only to such an extent as will insure at an vangleA of. about 45 vdegrees or more with the bottom of the channel; therefore, the active end of the tucking tool will be shaped to permit it to draw or tuck the fabric to the ottoni of the channel and beneath the lip extending at such angle.

4, If the materials are such that the arrangement' of cutting knife gives annoyance from clogging, its radius of actioncan be `increased so as to offer more clearance. Instead of producing a shear cut, as here shown, by the cutting edge of the Iclamping wheel, the face of the clamping wheel might be constituted a chopping block provided with a. proper cutting knife overlapping the face material of soft brass or other material may bey employed.
