Letters Patent lilo. 89,818, dated May 4', 1869. I

IMPROVE!) SOLE-CHANNLLING- AND FEATHER-EDG-ING- The Schedule referred to in these Letters Patent and making part of the same.

To all whom it concern: 1 y j yBe it known that I,`HENRY S. VROOMAN, of Boston, in the county of Suffolk, and State of Massachusetts,

, have inventedV Improvements in Sole-Ohannelling or l Feather-Edging Machines; and `I do 'herebydeclare that the following, taken in connection with thedrawings which' accompany and -form 'part of this speciiica tion, is a description of able those skilled-in the art to practise it. p,

This invention has particular reference to so ar' ranging an ordinarychannelling-machine, for` channelling 'the soles of boots and shoes, preparatory to sewing the uppers thereto, that the guide for` the edge of the sole vmay be adjusted, to vary the distance of the edge of the sole, or the width of a chamfer at the edge of the sole; also, to providing a rest for the under side of the sole in the intermediate space between the edge-guide and the toothedfeed-Wheel, and to -so constructing this rest that a knife attached to the upper portion or arm of the machine will pass down below the sole, and skive,

chamfer, or bevel the under surface at theedge; also, to a provision for adjustment of the upper smooth presser or feed-wheel horizontally, with reference to the edge-guide, and tothe arm by which it is supporte edge-guide for the sole I regard as preferable, either for ordinary channelling on the upper surface` of the sole, or skiving the `under surface, to the provisionI have already patented, January'l, 1867, for moving the arm horizontally, to adjust the cutters in theirrelation to the edge-guide,

ter or cutters to sole.

A shows a sideand sectional elevation of jthe feed- `Wheels and adjacent mechanism.`

B is a section" ou the line :c x.

vO is a plan ofthe lower feed-wheel, the edge-rest, and the edge-guide. adenotesfvthe front post of i the machine, in which is the bearing@ for the shaft of the lever or toothed `feed-wheel c.

jd is the movable arm, carrying the pin orshaft of the upperor smooth-faced feed-wheel e, the arm .dropthe surface of the upper roll ping by its weight, until my invention sufficient to eninvention relating to a movable Y in that the same resultcan4 be produced without changing the relation of the cut# the toothed feed-wheel carryingthe My invention is not,'broadly, in such an arrange` ment of mechanism as shall causethe sole to be bevback, the wheel may be is at suchv distance from the adjacent surface of the l lower roll as to cause the upper wheel to-be raised by the insertion of a sole between the wheels, the weight of the'upper wheel and the arm d, or downward'pressure brought to bear upon the arm, causing the sole to be pressed against Vthe teeth of the wheel c, so as to insure its feed-movement to the action of the cutter. f denotes the rest which supports the edge of the sole to be bevelled or skived.

.In the ordinary andwell-knownMcKay channellers, i as the cutter works upon th upper surface of the sole, the lower surface of the .sole adjacent to the edge is supported up'on a smooth rim `which is made upon the toothed feed-wheel beyond the teeth, the sole-next to its edge being 'supported upon this surface. It will be obvious, however,` that the wheel cannot be so made in this machine, because the bevelling-cutter must oc-N'Vf cupy the space just below the edge of the sole.v

I therefore make'the lower feed-wheel narrow, and

project from the post a'a stationary rest-plate, j; which the sole is held as it is fed to the action ofthe cutter,

and

its position determining the vwidth of the skiving, l

so e,

the distance-of the channel from the edge ofthe when any kind 'of channelling-cutter is used.

' To vary the width of the skiving, or the distance of the channel from the sole-edge, without moving the rest, this guide is made movable, andadjustable in position upon the rest-plate,-by means of a` slot and screw, lc. j Y; The guide is lslotted,-as seen at l, to allow the shank of the cutter to drop through it. s

To adj ust ythe upper feed-wheel to correspond to theV position of the edge-guide, that is to say, to keep the wheel up to the guide, and without moving the arm', I mount the'wheel on a screw-pin, m, on which it turns loosely, the wheel, in its rotation, beingconned y between the head, n, of the screw and a collar, o, and screwing into the arm d, as shown at A.

By turning the screw shown', the wheel is moved to I ward or from the guide, and, as the guide is moved moved up to it, so as to bear upon vthe 'whole upper surface opposite 'to which the cutter h is acting. It will be obvious that a ,smooth feed-roll, and adjustable horizontally within the arm, and fastened in anyone position by a setscrew, may be used instead of the screw m. y By these means, it will readily be seen that, while the cutter is varranged so as to skive the lower surface of the sole fed between the wheels, the sole adjacent vto the edge is supported, and prevented from bending down, and provision is made for guiding the edge of plain pin, the

the sole, and for adjustment of the edge-guide, (to vary the width of the skiving, or the distance of a channel from the edge,) and for thepressure upon the upper surface to correspond with such movements of the edge-guide.

I claim, in combination with the smooth-surfaced upper feed-wheel, the toothed-surfaced lower feedwheel, and the cutter or cutters, arranged to operate upon either surface of the sole, a stationary rest-plate,

Y for supporting the sole andedge to be skived or channeiled, substantially as shown and described.

Also, so constructing this rest-plate that the skiving-cutter or its shank can pass through or by the plate from the arm d, so as to bring the cutter to the under surface of the sole, substantially as described.
