MACHINE FOR THICKENING THE EDGES OF SOLES.

To all whom t may concern.'

Be it known that I, JAMES E. COLLINS, a citizen of the United States, residing at Danvers, in the county of Essex and Commonwealth of Massachusetts, have invented certain Improvements in Machines for Thickening the Edges of Soles, of which the following descriptiomin connection with the accompanying drawings, isa specificasirable that this size be not changed during the thickening and condensing operation. This invention therefore preferably provides for maintaining the size or width of the sole.

One of the objects of this invention is to thicken the edges of soles so that if it be desired to remove a thin shaving from the upper side around the edge, subsequently to securing the sole and upper together, but prior to edge trimming, as in the operation of fleshing, the original thickness of the edge of the sole will not be reduced by that operation.

Another object is to condense somewhat the material constituting the edge, whereby a cleaner cut is made by the edge-.cutting tool during the edge-trimming operation.

A further object of this invention is to form a groove or depression in the upper side of the sole extending around inside of the edge. This groove is deepest where the lower edge of the upper fits upon the sole, and inclines upwardly, whereby an abrupt bend of the upper is prevented as it turns away from the sole in some kinds of shoes. The edge of the upper lits down into this groove, thus preventing a projection of the upper above the surface of the sole at the meeting point.

A further object is to condense the ma- Speciication of Letters Patent.

terial beneath the groove or depression. This portion of the sole, being thinner than the remaining portion, would wear through more quickly were it not rendered more wear-resisting by condensing it.

The objects of this invention are best secured by using a machine which has a support for the sole and a conical roll which acts upon the side of the sole opposite that engaged by the support in such a way as to crowd material outwardly toward the edge of the sole, at the same time condensing it and forming a groove or depression in the sole inside of the edge. The surface of the conical roll is preferably provided with a series of grooves extending diagonally` of the surface in such a manner that they tend to work the material toward the outside of the edge of the sole. In order to maintain the size of the sole, an edge guide is provided against which the material that is moved outwardly walls up instead of spreading outwardly beyond the original edge of the sole. V

In the drawings,--Figiire l is a perspective view of the machine; Fig. 2 is a side elevation, partly in section, of the parts which operate directly upon the sole; Fig. 3 is a detail view showing a portion of the edge of the sole as it appears after passing through the machine, and Fig. t is a vertical section through a shoe showing the application of the sole thereto.

A base 1 which is to be secured to a bench or other support, carries a rear standard 2 and a front standard 3. A gear l is rotatably mounted on the standard 2, and this gear is turned by any convenient source of power, as here shown by a crank 5. A shaft 6 is rotatably mounted in hearings on the upper ends of the standards. This shaft carries a gear 7 on its rear end in mesh with the gear 4, a gear Sintermediate its ends, and a support for thc stock in the form of a bed roll 9 on its front end. The upper end of the front standard 3 has an enlargement l0 which carries an edge guide 11 and a stop 12, and which has a recess 13. The edge guide is preferably in the form of a rotatable roll. An auxiliary frame lll is pivoted at 15 to two ears 1G and 17 on the upper end of the standard 2. The front portion 18 of this auxiliary frame forms a bearing for a shaft 19 which has a bearing also in the rear part of the frame. A bifurcated extension 2() is secured to the upper end of the standard 3, and the bearing 18 which is preferably squared passes between the arms of the bifurcation. The shaft 19 carries a gear 21 on the rear end in mesh with the gear' 8, and a presser roll 22 on the front end. The presser roll has a conical surface 25 which preferably merges into a cylindrical surface 2G, and a reduced portion 23 for the accommodation of the edge guide 11. The conical surface may be provided with grooves which are preferably inclined to the elements of the cone sol as to extend diagonally of the conical surface. The presser roll is removably held on the shaft 19 as for example by the nut 24 which permits removal for repair or for the substitution of a new presser roll. The bearing 1 8 is held down by a stiff spring 27, the tension of which may be regulated by a set screw 2,8. AV rock shaft 29fpasses through the extension 20 and the recess 18, and'it carries' the tappetcam 30 which lifts the bearing 18 and the presser roll 22 when the shaft is rocked. rfhis lifting of the presser rollpermits insertion and removal of the stock.4 The shaft is rocked by means under the control yof the operator as by an arm 31 rigidly secured to the shaft and pivotally secured to a rod 32 having a treadle (not shown) at its lower end.

The operation of the machine is as follows: Upon turning the gear 4, power is transmitted through the gear 7 to the shaft 6 to turn the bed roll 9. The gear 8 by meshing with the gear 21 in turn transmits power to the shaft 19 so that the presser roll 22 is turned in the opposite direction from the bed roll. Upon rocking the shaft 29 the auxiliary frame 111 is turned upon the pivot 15 and the presser roll 22 raised to permit insertion of the stock a between the two rolls. The rock shaft is then released and the presser roll is forced down upon the stock by the spring 27 acting upon the bearing 18. The sole is fed through between the rolls by turning them in the direction indicated by the arrows in Fig. l. The sole is kept in contact with the edge guide 11, and the material which the presser roll crowds toward the outer limit c of the edge is banked up against this guide and the size of the sole thus maintained. The conical shape of the roll tends to produce a transfer of material in the tempered sole toward its edge, and the diagonally arranged grooves increase this tendency, their effect resembling that of a screw conveyer. Since the guiding face of the roll is contiguous to the ends of the bed and presser rolls, these three rolls together form a pocket into which material is forced constantly, and by which it is shaped. The

material in this pocket is put under pressure by the action of the presser rolland the result is the condensing previously mentioned. The presser roll therefore performs three important functions, viz.: thickening, condensing and grooving the sole. The conical portion 25 of the presser roll forms the depression I) while the cylindrical portion 26 forms the surface Z parallel to but higher than the main upper surface of the sole. Fig. 4f shows the sole applied to a McKay shoe. he lower edge of the upper lits into the yinclined depression ,Zi and the abruptness of 'the' bend is thus diminislied.` It will also be seen that the depression'provides a clearance for the upper.

While in the above description a complete machine has been described in detail in order to` fully set forth the preferred manner of applying the invention, it will be understood that various changes may be made in arrangement and details without departing from'th'e spirit ofthe invention.
