SOLE ROUNDING AND CHANNELING MACHINE.-

v I SPECIFIGATION formingpart of Letters Patent N 0. 649,125, dated May 8, 1900.

Application filed October 20,1899.

Be it known that I, HANFORD T. CROSBY, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Sole Rounding and Channeling Machines, of which the fol- This invention relates to machines for rough rounding and channeling the soles of boots and shoes while on the last; and it has for its object to provide a machine of this and adjusting the principal working parts.

The invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation of a sole rounding and channeling machine embodying my invention. Fig. 2 represents an elevation taken from the opposite side. Fig. 3 represents a front View. Fig. 4 represents a rear view, partly in secof Fig. 1. Fig. 6 represents a front view of portions of the machine. Fig. 7 represents a section on line 7 7 of Fig. 6. Figs. 8 and 9 are sectional views showing different adjust- Fig. 10 represents a perspective view of the work-rest, the channeling-knife, and the channelingknife holder. Fig. 11 represents a section on line 11 11, Fig. 10. Fig. 12 represents a bottom view of a channeled sole.

The same letters of reference indicate the same parts in all the figures.

In the drawings, a represents a work supporting and guiding Wheel, which is formed to enter the crease between the welt and upper, said wheel being preferably serrated on its face, which bears-on the welt. The wheel a is affixed to-a shaft Z), which is jour-, naled in a fixed bearing on the supportingframe 0 and is connected with the drivingshaft (Z by a Worm e on said driving-shaft and-a worm-gear f on the shaft 6.

Adjacent to the inner side of the wheel a is a fixed cutting bed or block g, which cooperates with a reciprocating rough-rounding knife or chisel h. Said knife is affixed to a slide or carrier 6, which is movable in a guide Seria1N0. 734,213. (No model.)

'7', hereinafter referred to. The carrier 1' is connected by a rod is with an eccentric wrist- 'pin 3 on the driving-shaft d. The knife h is detachably secured to the outer end of the carrier '5, which is split and provided withdovetail shoulders 11' t", Fig. 6, between which the knife is clamped by means of a clamping bolt 11 in thesplit end of the carrier. The guide j has a s1eevej Fig. 5, which is fitted to turn on a stud j, affixed to the frame 0, the guide being thus made vertically adjust able to vary the distance between the lowest portion of the wheel a and the cutting edge of the knife, and therefore the width of the projecting portion of the sole outside the bottom of the'welt-crease. The guide is held at the desired vertical adjustment by means of a screw j, Figs. 1 and 3, engaged with a tapped socket in the frame and passing through a slotted ear 7' on an arm 7' formed on the guide and nuts j", engaged withsaid screw and bearing on opposite sidesof the ear 3' I 9' is a fixed vertical ear or guide, which has a sliding fit between the arm 7' and a corresponding ear f, Fig. 3, formed on the guide j, the said ear j steadying the guide j and preventing crosswise movement thereof.

Z represents a rest or support for the face of the sole, which is adjustable horizontally toward and from the wheel a to accommodate any desired thickness of sole. The rest Z is attached to a slide Z, which is movable horizontally toward and from the wheel a in the guide t and is normally projected and held yieldingly with the rest Zat the minimum distance from the wheel ct by means of a spring Z attached at one end to a stud Z on the frame 'of the machine and at its other end to a stud on the slide Z. The rest Z may be retracted against the stress of the spring Z by abell-crank lever Z pivoted at Z to the frame, and a rod Z, connecting one arm of the lever Z to a treadle, (not shown,) the other arm of the lever Z being engaged with the slide Z.

The channeling-knife'm is affixed to anarm or carrier m, which has a compound connection with the rest-carrying slide Z, so that the channeling-knife moves horizontally with the rest Z toward and from the wheel a and is adapted to reciprocate horizontally in a direetion parallel with the feed movement of the sole to cut the channel therein and to move vertically toward and from the roughrounding knife it while reciprocating horizontally to vary the distance between the channel and the edge of the sole, as shown in Fig. 12, where the mouth 1' of the channel is shown farther from the edge of the sole 8 at the shank than at the fore part. The said compound connection, as here shown, comprises an angular block n, to which an car an on the rear end of theknife-carrying arm m is connected by a horizontal pivot n, which permits the arm m and channeling-knife m to be adjusted vertically toward and from the rounding-knife h. The base of the block at is connected by a vertical pivot nF'with the rest-carrying slide Z, said pivot permitting the block it and the arm m, with the channeling-knife, to oscillate horizontally, the pivot 91. also causing the block n, arm m,

.and channeling-knife m to move, with the slide Z, toward and from the wheel (t.

The means employed to reciprocate the arm m and knife on horizontally comprise a camslot 0 in the rounding-knife slide '5 and a stud m on an arm m formed on the arm m, said stud entering the cam-slot 0, which is formed to impart a short reciprocating movement to the arm m and knife m in a direction substantially at right angles to the movement of the slide 2' and rounding-knife h.

Means are employed to raise and lower the channelingknife while the machine is in operation, the reciprocating movement of the knife being unaffected by the vertical adj ustments thereof. Said means comprise alever p, pivoted at Z to the frame and having at one end a bearing-screwp, and a rod 13 connecting the other end with a treadle. (Not shown.) The screw p bears against the lower end of a plate or slide g, which has a limited verti cal movement on a vertical face on the frame 0 and is secured to said face by screws q q,

passing through vertical slots (1 g in the plate q, said slots being shown by dotted lines in Fig. 2. The plate g has horizontal ears q (1 between which the channeling-knife arm m has a sliding fit and is adapted to oscillate horizontally. The plate q is normally held at its lowest position by a spring q, connecting one of the ears (1 with a stud g on the frame 0, the channeling-knife being thus held at the maximum distance from the rounding- Tknife, Fig. 8. \Vhen the lever 19 is moved by the depression of the treadle connected therewith, the plate q is raised and its ears (1 cause the arm m to swing upwardly on the pivot or, thus adjusting the channeling-knife toward the rounding-knife, Fig. 9, the horizontal reciprocating movement of the channeling-knife arm m continuing between the ears g (1 The extremes of the vertical movements of the ehannelingknife may be determined by adj ustablc stop-nuts it on a screw- .threaded rod 15', which is connected with one of the ears The rod '6 passes through a fixed car i on the frame a, one of the nuts 25 being above and the other below said ear.
