SOLE-TRIMMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 469,720, dated March 1, 1892. Application filed F ruary 24, 1891. Serial No. 382,496. (No model.)

To all whom it may concern.-

Be it known that I, JAMES H. REED, of Lynn, in the county of Essex, State of Massachusetts, have invented certain new and useful Improvements in Machines for Cutting and Ohainfering Shoe-Soles, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a front elevation of my improved machine; Fig. 2, a top plan view of the rotary cutter-head, fixed guide-cap, and adjusting mechanism; Fig. 3, an elevation showing the inner side of the cutter-head; Fig. 4:, a like view of the opposite side; Fig. 5, an end elevation of the fleshing or chainfering cutter-head; Fig. 6, a vertical longitudinal section of the same with the knives removed; Fig. 7, a perspective View of one of the chamfering-knives, and Fig. 8 a crosssection of the pattern with the sole-stock in position thereon. Fig. 9 shows an enlarged view of the cutter-head for feather-edging the sole.

Like letters and figures of reference. indicate corresponding parts in the different figures of the drawings.

My invention relates especially to machines for cutting shoe-soles by pattern and chamfering the same; and it consists in certain novel features hereinafter fullyset forth and claimed, the object being to produce a sim pier, cheaper, and more effective device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the body of the machine, which comprises astandard supported by legs 6 and provided with a horizontal head d. On said head two journalboxes f are mounted, in which a horizontal shaft g is journaled. At the rear of the standard a horizontal shaft h is mounted, bearing a loose pulley j and fast pulley 7 connected by a belt 7a with any suitable source of power.

On the opposite end of said shaft a pulley m v is mounted.

A suction fan-blower B, of suitable construction, is supported by a bracket 19, mounted on the standard, anda pulley on the shaft q of said blower is connected by a belt I' with the pulley m. Pipes 25, leading to the blower, are provided with semicircular heads '0, which partially inc-lose the ends of the shaft g outside the bearings f. Said heads are designed to collect the dust and chips from the leather which are drawn into the mouths to of the pipest by the blower and ejected through its discharge-pipe m. The shaft g is provided centrally between the bearings f with a pulley y, connected by a belt ,2 with the pulley on the drive-shaft h. On one end of the shaft 9 a rotary cutter-head 15 (see Fig. 2) is secured. Said head is provided with a series of peripherally-arranged shaping-blades 16, having V-shaped cutting-edges 17. (See Fig. 2.) The bodies of the blades 16 are slotted longitudinally at 18 (see Fig. 3) and adjustable radially on the inner face of the head 15 by means of screw-bolts 19 and nuts 20. The flange 21 on said head serves to properly center said knives. Rand-knives 22 are secured to the face of the head 15 by screws 23, said knives being arranged to alternate with the shaping-knives 16. The rand-knives have beveled edges, as best shown in Fig. 3. A rod 25 (see Fig. 2) is arranged at the rear of the machine parallel with the shaft g, and a gage mechanism 0 is mounted at each end of said rod, said mechanism comprising a sleeve 26, adjustable by a set-screw 27 on said rod, from which an arm 28 projects laterally at right angles to the shaft g. A rod 29 is fitted to slide longitudinally in a sleeve 30, formed centrally on said rod 28 and secured therein by a nut 31. Said rod 29 bears on its inner end a stationary guide-cap 32, which is adapted to inclose or partially inclose therotary cutter-head 15. The walls of the cap 32 converge inwardlyat 33, and an annular flange 34 is formed at the mouth thereof, said flange being provided iuteriorly with an annular rabbet 35. The body of the cutter-head 15 ispe'veled at 36 to center in said cap. The outer end of the rod 28 is provided with a sleeve 37, in which a bar 38 is adjustable longitudinally by means of a set-screw 39, said bar bearing a segmental guard-plate 40, which engages the outer face of the cap 32. By releasing the rod 29 in the sleeve 30 the cap 32 may be moved forward onto the cutter-head to get said rod into alignment with the shaft g, where it is set by the nut 31. The

knives

16 and 22 enter the rabbet 35 on the cap 32, and the cutting-surface of their blades may now be ad- 10 justed by moving the gage O on the rod to expose the desired portion of said blades, particularly of the rand'knife 22 and securing it by means of the set-screw 27.

In Fig. 8 the pattern D is shown with the x5 sole-stock E secured thereto. The body of the pattern 45 consists of a sheet of metal cut in the desired shape, to each face of which a wooden block 46 and 17 is respectively secured. Said blocks follow in outline the shape '20 of the pattern, but are less in diameter than said pattern, the space 48 between the edge of the pattern and the edge of said blocks being equal to the depth at 49 of the flange 3 1 from the outer face of the cap 32. The

2 5 stock E is attached to the blocks 46 or 47 in the ordinary manner of securing sole-stock to a pattern and projects beyond the edge of said pattern, leaving a space 50 between said stock and pattern which is equal in breadth 0 to the breadth of the flange 3 1 on the cap 32. In use, the cap 32 being adjusted over the head 15, the operator holds the edge of the pattern 45 against the side 49 of the flange 34, said flange entering the space 50 between the pattern-body and stock E. The stock thus comes into contact with the knives 16, which reduce it to the shape of the pattern, the edge of the pattern-body being turned and held in engagement with the face of the cap 32 by the operator.

For cutting an outer sole a straight-edged knife is employed instead of the V-shaped knife 16; but when it is desired to shape flexible inner soles such knives turn the edges on the inner sole WltlZOlll] cutting. To obviate this I employ the V-shaped blade, the opposite edges of which stand at an angle to the sole-edge, and draw-cut said edge toward the center, preventing the sole from turning.

Several of said flexible soles may be cut at the same time. \Vhen soles are shaped by rotating knives, as described, a thin rough or feather edge is left on the grain side of the leather. To remove this edge the beveled rand-knives 22 are employed, the cut of said knives being gaged by the overlapping of the cap 32. Adjacent to the cutter-head 15 a treadle-actuated chamfering or facing cutterhead II is splined on the shaft g. The head H is provided on its working face with a series of radiallyarranged straight-edged knives 51, behind which openings 52 are formed through the body of the head for the shavings. Segmental openings 53 (see Fig. 5) are also ,6 5 formed in said head to receive the blade 16 on the cutter-head 15 when the chamfering-head is forced forward by its treadle mechanism. The working face of the head His beveled at 54. (See Fig 6.) Said head comprises a body portion 55, in which the spline-slot 56 is formed, and a sleeve 57, which is adjustable longitudinally on said body and is secured by a set-screw'58. The knives 51 are secured to the body portion 55 by screws 56. By moving the sleeve 57 on said body the out of said knives may be gaged. The treadle mechanism for said head comprises a bellcrank lever 60, pivoted to the standard-head d. To one arm of said lever a bar 61 is pivoted, its upper end being pivoted to a ring 62, encircling the body of the head H. To the opposite end of the lever 60 a rod 63 is pivoted and connected at its lower end with an ordinary foot-treadle 64. The rod 63 is screw? threaded at 66, and nuts 67 are turned thereon on opposite sides of an arm 68 on the standard A, through which said rod 63 passes. By adjusting the nuts 67 the treadle movement in throwing the head II may be regulated. In use when the sole-stock is secured to the pattern the grain side is in engagement with the edge of the cap 32. By forcing the head II against the flesh side of said sole the edge may be faced or chamfered by the knives 51, conjointly with the shaping of the sole by the cutter-head 15. For featheredging the soles a similar cutter-head H is mounted on the opposite end of the shaft g. In the gage O at this end of the shaft the guard-plate 400 is pushed by a spring 70, its rod 38 sliding in the sleeve 37 of the gage. The cutter-head 15 is omitted from this end of the shaft and inclined feathering-blades k (shown in Fig. 7) are substituted for the blades 51 on the head H. The inclined cutting-edge 71 of said blade bevels or featheredges the edge of the sole, and said blades are provided with an angular cutting-flange 72, which forms a channel-shoulder on the sole at the inner edge of said bevel. When the sole has been shaped and faced by the cutter-heads 15 and 'H, it is disposed between the spring-pushed guard 400 and the cutterhead H forfeather-edging, as described. The leather shavings and other refuse falling from the cutter-heads are received by the hoods 2; and drawn into the pipe-mouths w by the suction-fan B, from whence they are ejected through the discharge :0.

Having thus explained my invention, what I claim is 1. The shaft g and actuating mechanism, in combination with the non-rotating guide-cap IIO having an outwardly-flaring inner wall and adjusting mechanism therefor, a treadle-actuated cutter-head splined on said shaft and beveled at its front end to center within said cap, and radially arranged facing-knives thereon, substantially as described. 7
