To Yall whom it may concern:

Beit known that I, JOHN N. BUsELL, aat Boston, in the county of Suiolk land ommonwealth of Massachusetts, have invented certain Improvements in Feather -l'ldgingl Machines, of which the following descrip tion, in connection -with the 'accompanying drawings, s a specification, like reference characters'on the drawings indicating like parts in the several figures.

This invention relates to feather-edging machines which 4are used for. fleshing or beveling the faces of shoe soles.

The invention ia designed to provide Vfor effecting various advantageous adjustments which render the machine capable of use forV different purposes, and to supply important improvements in the general -organization and lmode of operation of feather-edging machines.

Different types of machines have been used heretofore which may be', classed under the general designation of` feather-edging machines. Some of them have been usedl fory eshing soles,z`. e., smoothing off the {iesh side of a sole in Aaf 'narrow peripheral area in order -to provide a smooth surface and uniform thickness for that .portion of the sole which isl immediately attached to the upper'.` 'In performing -this fleshing ,o era- I .-'tionthe plane'of'the smoothed perip eral i area is preferablyat avery slight. anvleto -the plane of the sole face, and the thic ness ava of the'sole'edge is usuallynot materially changed except inso far as-is necessary m order to ,secure uniformity. 'Machines .have

or 4chamfering a sole edge, or a part ,thereof,-in. order to produce a; thin edge* whchfsliall `give the. finishedA shoey an appearance ofy lightness, or

' in order toa-endet` some Aportion of the sole normal thickness of the ,sole in orderto give Y a'ndto Vcause a1 'more flexible.,y In? such a case it may be Vpreferred that 'the beveledV or chamfered portion be at a considerable angle to the face o f A the sole. This use of these machines is `welll exemplifiedin the o eration of shank-re-y ducing. It is consi ered desirabletliat the oppositeY edges ofthe shank portion of a shoe sole be materially lthinner ,than l the exibility, to permit of 'a ,superior finish,

ight appearance in 'the com- 1 pleted shoe.. .lothisfend the opposite'edges imitation of a turn shoe.

of the shank of a sole are sometimes beveled at a considerable angle. In womens shoes the sole is frequently thus beveledentirely around its periphery to contributeA tothe In iieshing or bevelingv shoe soles the anale which the fleshed or beveled'portion marlies with a Sole Afaeevaries with different systems or factory standards.- Also ,it may be desired to give' a sole edge a deep or a shallow bevel, or to malte bevels of different widths or depths on different soles.

y Machines have been used heretofore which y were intended to feather-edge soles according to different re'uirements as `to dimensions of the bevele or fleshed portion, but.

'the 'intricate adjustments of these machines have consumed Ia great deal of the operators time and have been only indilferently successful.. The best machines hithertoV employed have been susceptible of very limited use only in feather-edgino'i in` different dimensions, and it is thought that no' means has4 been `supplied heretofore vfor featheredging at di erent angles except by removing .certain elements of machines and replacing them by others of different-character, an4 inconvenient yand clumsy-arrangement which practically resulted in the creation of new land different machines to meet the requirements of lieveling at different angles.

' The present invention contemplates a machine which is capable o'f'fleshing or beveling a soleI to en y suitable'width or depth,

4and at any pract1cable angle to a Asole face.

One object ofthe invention, 'among several others,y is Ato provide means whereby the machinema be readily arranged for fleshing or beve ingfa't different angles; and to thisend an important feature of the invention consists in the combination of'a'cutter with work-controlling devices constructed and arranged for Vfeather-edging' soles at diii'ereant'angles Other principal yand subordinate features of the `imentio'nwill be explained in the lvfollowing description and willbe defined in the claims.

. The 4invention will be described herein as `'embodied i'nLal machinelhaviilga rotary cut` ter an work-controlling devices comprising-afaoe-'gude and ain edge-gage. A shoe sole held in tliehands of 'the' operator, is introduced to the action of theanachine by lno i presenting the outer face of the. sole against the face-guide and the edge of the sole. ad-y jacent to which the sole is to be fleshed or beveled, against the edge-gage. The sole 5 having been introduced in this manner. the rotary cutter performs .its feather-edging function in the manner and with the result determined by the adjusted position of the work-controlling devices.

It is to be understood thatnothng herein contained is to be construed as limiting .this invention to .the specific ei'nbodilncnt. here shown and described. n In the accompanying drawings, Figure 1V is a side elevation of the head of the machine; Fig..2 is an end elevation of the head of the machine showing Ain dotted lines the position of the shoe sole when its shank portion is being feather-edged; Figtg is a perspective o the rotary. `cutter; Fig. 4 is a perspective of the edge-gate; Fig. 5 is a perspective of the face-guide with the edge-gage secured thereto; Fig. 6 is a detail in section showing the 'work 1n engagement with .the edgeage, the face-guide and the rotary cutter.'4 11g. 7 is a perspective of a shoe sole having its shank portion featheredged on both edges. The 'frameQ of 44for supporting a shaft 6 which may be turned in any suitable manner as through a pulley 8. vThe shaft carries a rotary cutter head 10 which may be secured thereto in any suitable manner. The cutter head is '2564 preferably constructed as. shown in Fig. 3 -rzivith a disk portion havin an integral hub 112. The'inner face of the c isk portion is cut Vawav to 'form a number of inclined surfaces 414 (there being three as shown) and oppo- 40 site'surfaces 16 which are preferably slightly,

inclined toward the surfaces 1l. The surfaces 14 and 1G if extended would intersect in a line somewhat beyond the outer face of the disk ortion. Radial slits I8 are therefore pro( ter head. Cutting blades 20 .having shoulders 21 are secured to the inclined surfaces 14 by bolts 2:2 extending through the slots 24 in the bladesandscrewiug into the cutter head. rashers are preferably 'laced between the blades and the heads o' the bolts. Br loosening the bolts the blades maybe adjusted readily asthey wear. awey`or the may be removed for sharpening. The shou ders '21 indicate the point to which theblades may he ground away in sharpening them from time to time. Oti'sets '2 5 are preferably spaced from the surfacesvl'f a distance oo rresponding to the thickness of the blades 1n order to assist in holding the latter in place. It will be'fhus seen that the cutting blades instead of being arranged radially as custolnmy are arranged' diagonally on the cutter the, machine has bearings uced in the outer face of the cut-4 sets '25 and are thus prevented from yielding during the cutting operation. a defect which exists in the use of' radial blades mounted in slots' in .the cutter head. The .cuttino edges of the blades are set to project throng i thc slits 18 'slightly beyond the outer face of the disk portion in the same manner that the blade of 'a wood planeprojects beyond thel bottom face of the plane. The. outer face of the disk portion is preferably slightly beveled in order that the cutting blades may generate the frustum of a cone 'during rotation. The surfaces 1G -are preferably beveled ofi" at their outer corners to form sur-- faces 27'. Guards 26 are secured adjacent to the outer corners of the cutting edges and are preferably located in grooves in the surfaces 2.' These guards may be mounted so as to permit of their beine adjusted as by means of a slot therein and a screw exten ing therethrough into the cutter head. The outer corners of the cutting blades are removed or rounded off and into the lspaces thus left there extendprojecting portions 29 of -the guards 26 as shown in Fig. 2. The guards me set so thatfthe projecting portions extend slightly beyond the outer face of the cutter head 4in order to prevent the cutting'ed0'es-f1'om cutting into vthe stock too far at t ie Jeriphery of the rotary cutter.l

A` Segmente hand guard 2S is placed so 4as to partially encircfe the rotary cutter.

This hand guard maybe supported in any suitable manner as by a bracket 30 attached to aV stud 32 fitting into u socket 34 on the frame. 'Ilhe stud 32 is movable in the socket and may be secured in adjusted position by j a s'et screw 36. f Theangula-r adjustment of the hand guard is facilltated by an`ad`usting screw 3S at the top of said guard.l his screwtis threaded through the guard and abats against a stationary part of the frame. By turning said screw the guard may be 'adjusted to bring it a.. closely'as desired to the rotary cutter. The bracket 304 may also conveniently sup' ort a work uard 40 which coperates-witi a face-gui e 42 to Lcontrol the work, which during the operation of the machine is positioned )et-Ween -their adj accnt faces. An edge-gaffe 44:, is adjustably secured to the face-guide as hereinafter set forth. The primary support for the face-guide and the edge-gage -is a stud 4G prefeab y non-rotatable which is secured by a split sleeve 4.8 on the frame.' Said sleeve may be tightened ,to hold securely the stud by means of a clamp 50. When said clamp is loosened the stud may be moved axially by means of an adjusting screw 52.,.whic i threads into the sleeve and has a collar 54'125 engaging the slot in the stud. r On theouter end' ofv he stud "s a; split sleeye 6which constitutes a secondary support for the face.

ide' 42 and edge-gage 44.. l,Said Y split head. They are 'held securely upon the 1n- 65 cliaed surfaces 1.4 by the bolts 22 and the olf- .S cove lisV provided' with a clamping- 'gleyice 1A80 the upper portion .of the face-guide.

whereb)r the sleeve may be closed to grip tlie stud -t-. lVhen said-clamp is loosened thel sleeve G may be removed from the stud or it may be adjusted thereon either axially or aiigularly. It is convenient to adjust the face-guide and edge-gage preliniinarily by rocking the sleeve 56-on tlie'stud -lG and effecting approximately the adjustment of said sleeve. When this approximate adj ustment. has been ellected= the linal iniiii'ite adjustment may be accomplished by turning the adjusting screw Depending from the sleeve 56 is a rigid arm which 'is bifurcated for :1 portion of its thiekness'toprovideV for the reception ofan' adjusting pin G2 which serves a purposefpresently to bemlescribed. Pivoted to the arm 60 bv means of a. pivot bolt- (S4A is a ca rrlcr G6 which constitutes the immediate support for the face-guide ft2 and the edgee4-l. This' carrier is bifuieated as shown 1li ig."2 and is provided with parallel rabbe'ts on the inner sides of the ar'nis )reduced ,by'the bifurcation. The. face-gui e 42 tits upon 'and between said 'rabbets and is slidable` up and down n )on the tracks thus formed. .Said carrier lias a'rigid linger GS preferably-in a plane perpendicular to the axis of the pivot 6l. 'The adjusting pin 62 is.pivoted' to said finger b a pivot boftf() wlich is preferably paral el to the axis of the pivot G-l. It is evidentthat the adj Aust;`

in pin GQ may be moved lengthwise to e eetangular movement of the carrier (3G about the pivot 64 and the angular adjust-4 ment of the faeeruide 42 and edge-gave -l-t is thereby etl'eete The upper end o? the pin 62V rpasses through a freely rotatable stud 72. V A set screw 74 screws i'nto the end of the stud T2 yso as to engage the pin' 62 to .si-eure it in adjusted position.

A preferred forni of the face-guide and 'the edge-gage are shown in perspective in F igi' hind in section in Fig. 6. The faceguide is movable lengthwise of' the bifurca-` tion of the 'carrier G6, as previouslyrdescribed. A. set screw 76 threading into the vbody portion of the face-guide has a washer 78. which, bears' a ainst tlie outer faces of the arms produce by the bifurcation of the carrier. By. screwing up said set Screw, tlie 4face-guide may be secured in adjusted posi- -tion on the carrier. The edge-gage -l-l rests .upon and is movable on ast-.at 80 foi-ined op screw 82 is threaded into the u iper' portion ,of the face-guide. and is rotatab y connected to theedge-gage by the collar By tui-ning said screw the edge-gage may be moved i in and, outwith relation' to the face-guide lto accommodate soles of different thicknes-ses. A screw SG 'also extends throi'igh the upper portion of the face-guide' and is .threaded into a relatively tliinportion 88 i formed by splitting said upper portion. By

turning the. screw SG the lli'iii portion S8 nniy be drawn down Sous to pinch the scri-w Si and secure the edge-gage in adjusted position. 'lhetalge-gagc is provided with a projecting lip Slt) having a.comparatively thin edge which engages the stock, as shown in Fig. t?. to prevent the saine. from being' drawn away from the face-guide by the cutter. v

l't. will be apparent that the above-described device comprises a nuinb'er of effective adjust-ments. The 'cutting blades niay be readily adjusted inwardly and olitwardly in 'order to regulate the amount which they project beyond the cutter head by loosening the 4screws 22.4 The face-- guide and edge-gage may be moved toward and from the cutters in order. todetermiiie the depth to which the cutters are to peneti'ate the sole by moving the s )lit sleeve 5G azially on the stud 46. rl`lie e ge-gage may be mov'ed lengthwise of the carrier 66 in order to determine the widtlrof the area to be eut by the'cuttingblades'by loosening'tlie screw 'T6 and moving said edge-gage and face-guide to the desired position. The edge-gage may be moved inwardly or o'utwardly relatively to the face-guide in order to accommodate soles Vol different thicknessus' by loosening the. screw 86 and turning tlie 'screwA 92. l'llie fama-guide l'and edge-gage may be given any desired align-- lar relation to the cutters in order to determine the angle. at which. the cutterblades are to act. upon the work by loosening the set screw 7,4 and moving the adjusting pin (l2 longitudinally to rock tlie carrier 66 on its pivot G4 to the desired position. 4It; is obvious that. the operation of sliaiilc-reduc-. ing as illustrated in- Fig. vis but one of the operations which may be performed with the machine shown in the drawings. For instance., by turning the sole all the way around with its ed ein Contact withthe edge-gage 44 tlieso e will be feather-edged all the way around', or if desired it inay be feather-edged around the toe portion only from one sideo-f he shank to the other.
