TOOL FOR FINISHING THE EDGES OF BOOTS AND SHOES.

SPECIFICATION forming` part of Letters Patent No. 236,145, dated January 4, 1881.

Application filed July 24, 1880.

1'0 all 'whom tt 'may oo'ncern -Be it known that I, SAMUEL N. OORTHELL, of the town of Quincy, State of Massachusetts, have invented Improvements in Tools for Finishing Ithe Edges of Boots andShoes, of which theV following is a specification.

I`his invention relates to improvements in tools for finishin g the edges of boots and shoes;

I and the invention will, in connection with the annexed drawings, be herein fully described, and specifi cally detined in the appended claims.

Figure 1 is a side elevation of a machine having my improved tools thereto applied. Fig. 2 is a detached reverse view, showing the rand-tool and gages as applied to the machine. Fig. 3 is a side elevation of the randcutter as viewed from the right in Fig. 1 and left in Fig. 2. Fig. 4 is a detached elevation of the Vertical rand-gage as viewcd from the zo left in Fig. land right in Fig. 2. Fig. 5 is a top or plan view ofv said gage. Fig. 6 is an under-side or inverted-plan view of the horizontal rand-gage. Fig. 7 is a 'detached elevation, showing the edge-trimmer disk-gage as viewed from the left in Fig. 1, said disk being in part broken away to show the cutter behind it, the Vertical gage being also shown in elevation. Fig. 8 is a detached view showing, in partial (liame'tric section, taken through one of its teeth, the edge-cutter and its diskgage. Fig. 9 is a detached longitudinal section taken through the rand-cntter, and showing its shaft transversely taken away. Fig. 10 .is a top or plan view of my Vertical edgecutter gage. Fig. 11 is a detached Vertical section, showing a shoe-sole edge as it leaves the pegging-machine and before commencing the finish of the edge. Fig. 12 is a section similar to Fig. 11, but showing the sole-edge as operated upon by the rotary rand-cutter,

which latter and its gages are shown in position by dotted lines. Fig. 13 is a section similar to Figs. 11 and 12, but showing the soleedge as completed by my improved cutter,

which latter is shown in position by dotted lines. Fig. 14 is also a-section similar to the preceding, but intended for illustration in showing the result of the previous methods and tools used for a similar purpose.

In these views, A represents a frame, which may be of such form and size as will best (No model.)

adapt it to,the conditions and place where it is to be used.

B is an arbor journaled in boxes at the top of the frame, as shown.

O is a pulley secured on arbor B, to receive the belt by which rotary motion is imparted to said arbor and the tools thereon mounted.

At the opposite or left-hand end, Fig. 1, the usual shank-trimming tool ais mounted. This tool oonstitutes no part of my invention. ln said shaft, nearer the journal bearings, is mounted the cutter b and rand-disks o, which are secured thereon between the fixed collar d and the screw-nut e in the usual manner.-

The cutter b is of well-known form and construction, except the narrow groove f, which is cutin its teeth at the intersection of lines g and h, as is plainly shown in the enlarged Fig. 8. The object and office of vsaid groove f will be hereinat'ter specitled. i The disk c is formed with the holes i, which are so arranged therein that when mounted with cutter I) onl arbor B they are just within the circumferential line described by the lines g of the teeth of the cutter, and are coincident with the open spaces between said teeth, as shown in Fig. 7. i

In Figs. 1, 7, and 10 a gage-support, j, is shown, which is secured in position by the vcap-screws of the jonrnal-bearin g of the frame,

or it may be secured to the frame in any desired manner. At the outer end of this sup- .port two curved arcs or fingers, lc lc, are' secured by the screw l, which passes through the slots m m, Fig. 10, in said ares, whei'eby vthesame may be so adjusted as to leave a greater or less space between the lower ends 'of said arcs, in order to allow the teeth of cuttel'l b to extend below the same to the required go extent in vthe finishing of different kinds of boots or shoes.

An arbor, D, is journaled below arborB in -projecting sleeve F of frame A, or its equivaplan in Fig. 3, and it is of slightly less diameter than the gage-disk o.

A gage-holder, p, is seoured to sleeve F by the screws s, as shown, and so as to be vibrated thereon, in order that the end next to cutter n, and in which stem u' of gage t is secured by setserew n, may be raised or lowered, as required. The form of said gage tand its relation to arbor D are shown in Fig. 4, and said gage may, by means of set-screw o, be adjusted at the desired distance from arbor I). It may also, by the described vibration of holder 1), be arranged oblique or parallel theretO.

A gage, w,whose face is oblique to the axis of arbor D, is horizontallyadjustable relatively to eutter n, and it is secured to sleeve F by screwi ,which passes through the slot in stock x, Fig. 6, such stock being held from rotationv on said screw by steady-pins 011 either side thereof, as shown by dotted lines in Fig. 1.

The operation of said tools is as follows: After the sole 1 and upper 2 of the shoe have been united, as shown in Fig. ll, the next operation is to cut the bevel termed the rand?7 (Shown at 3 in Figs. 12, 13, and 14.) Heretofore this has been done by employing disks 0 as a guide, which, being inserted and traveling in the converging space between the sole and upper, thereby operated as a guide; but I adjust the vertical gage t, against which the sole-edge bears, at the desired distance from the periphery of eutter a to allow said cutter to cut the rand to the required distance from the edge of the sole or width of the surface thereof. I also adjust the gage w at such distance from the face of cutter n that the thickest soles of a lot or case of boots or shoes (intended to be of uniform thickness at the edge) will pass between such edge and eutter, while, by varyiug the position or angle of the plane of the thinner soles relatively to the eutter, the desired width of rand may be cut therein without moving gage w; or, in other words, when disk o served as the guide or gage the rand was cut relatively to the top of the sole, while, by the use of gage w, such rand is now cut relatively to the bottom of the sole. In Fig. 7 the position of the shoe sole and upper when the rand is being` cut is shown by dotted lines. After the rand has` been cut' by rotary eutter n in the manner described, leaving the sole in the condition shown in Fig. 12, the shoe is then'sub- ]'eeted to the action of cutter bon shaft B, the shoe being held in the hands of the operator, as when cutting the rand, beneath the cutter, and with the edge of the sole resting upon the arc-like fingers lc k, as shown by dotted lines in Fig. 7. As the edge is moved past said eutter the inner face of the perforated disk c acts upon the rand and smooths the same by the action thereon of the angles at the oriiices of holes z' in said disk, while the edgeet of the sole is cut by the line q of cut ter d, and the grooves fin said eutter forms and finishes the corner 5, as shown in Fig. 13. Without such groove the corners of the sole will be slightlyrounded, instead of presenting the full appearance which said groove causes, and which is regarded as the best style of a tinished edge.

In Fig. 14 the lower corner of the sole is shown at 6 with a bevel or short face cut by line h ot' eutter Z), which would result in case of a sole thicker than those for which eutter b was adapted if the rand was cut with disk 0 serving as the guide or gage, instead of gaging from the bottom of the sole with gage w, as described.

I am aware that heretofore inventions have been patented for the same purpose, wherein were embodicd gages by which to adjust the shoe-sole edge relatively to the cutters, and that the rand guides or gages so employed have been perforated as described, and I make no claim to such perforated rand-guides, or, broadly, to the cutters or gages or parts therewith employed, my invention being contined to the subject-matter defined, set forth, and einbraced in the several claims which are appended to or constitute the termination and summing up of the specification, wherein I have set out and described my invention in connection with such other unclaimed parts as were necessary for the proper elucidation of the functions of the said specific devices, which, as above stated, constitute the precise features or substance of my invention, which I hereby seek to protect by Letters Patent.

The gage w may be adjustably pivoted to its stock x by the pivot 7 in Fig. 1.

I claim as my invention- 1. In the rotary eutter b, the circumferentia-l groovef, formed in the teeth thereof, at the intersection of lines r/ lt, whereby a full finish is imparted to the sole at the angle thereof, substantially as specified.

2. In combination with the rotary edgecutter I), the gage kk, to control the depth of cut upon the sole-edge, substantially as specilied.

3. In combination with rand-eutter n, the gage w, pivoted to the holding-stock x, and the latter slotted to receive the holding-screw y, whereby said gage may he adjust'ed in its distance from the cutter,and may be vibrated upon its pivot to the desired obliquity, substantially as specified.

4. The combination of arbor D,With itsrandeutter n and gage-disk 0, with the gages tand w, and arbor B with its eutter b and gage-disk c, all substantially as and for the purposes specified.
