I 107 I A mg 12 14!! w W 360 or a so-called bottom channel) which can'be 'most readily closedand is most likely to remain permanently closed, while the shank portion of the shoe, which is not sub ect to I wear, is provided with an American or edge channel whereby substantial feathering (or shank reducing) and the consequent production of a light edge at that part is made practicable without unduly weakening the seam.

A further advantage of an American channel inthe shank is that, in the case of Louisheeled shoes, the channel may be made to blend readily with the flap since the flap and the channel lip may both readily be made of the same thickness where they join.

In view of the foregoing it isone'object of the present inventionto provide for channeling a sole with a bottom or face channel at one part of the sole and an edge channel at another part of the sole at a single continuous operation, thus doingaway with the i V necessity for practicing the present expensive method of transferring a sole from one machine to another when the sole is to be channeled with two types of channeling.

To thefaccomplishment of the above object, the invention, in one aspect, prov des a novel. method of sole ch'annelmg whlch consists-in relatively moving a sole andmeans for channeling a sole to form a continuous channel in the sole, and changing the relation between the sole'and the channeling means during the continuous channeling operation in such a manner as to effect face or bottom channeling in one portion of the sole and edge nel in the sole margin, and subsequently tiltingthe knife to position it so that its curved portion becomes effective to cutiinwardly ,from the grain surface of the sole, and continuing to feed-the sole past theknife to form an'English channelin another portion of the sole margin, the feed of the sole continuing also during the tilting'of the knife so that the knife cut will extend across the corner of the sole edge'and a gradual and even, blending of the American and English channels will be effected. As illustrated, the

above-described tilting of the knife takes place at thejunction between the shank and forepart at one side of a sole and a similar tilting of the knife, .but in the opposite direction, takes place at the junction of the forepart and shank at the other side of the sole so that anAmericanchannel is formed 11 at both sides of the shank and an English channel is formed around the forepart of the sole.

Another object of the invention is to provide an efficient and reliable machine for effecting two-type channeling of a'sole in a single continuous operation.

l/Vith this object in view the invention resides in the provision, in a channeling machine, of means for forming a continuous channel in a sole, and means for relatively adjusting the sole and the channeling means during the continuous channeling operation in a manner to produce a bottom channel, i. e., a channelin one side face of the sole, in one portion of the sole margin and an edge channel, i. e., a channel in the edge face of the'sole, in another portion of the sole margin. In the illustrated machine cooperating upper and lower feed Wheels are arranged to feed an unattached sole past channeling, instrumentalities which, in accordance with one embodiment of the invention, comprise two knives, viz., a straightedged knife hereinafter called an American knife, and a curved knife hereinafter referred to as an English knife. In this embodiment of the invention the illustrated knives are both mounted upon a single knife carrier which is mounted with provision for tilting adjustment and upon which the American knife ismounted for sliding movement to and from position tovoperate'upon the sole. The illustrated knife carrier is tiltable about a center solocated with respect to the sole that tilting of the knife carrier will shift the English knife edgewise of the sole so as to cause the knife to cut across the corner of the sole edge. Treadle mechanism is provided whereby the knife carrier may be tilted at the will of the operator and as hereinafter explained the knife carrier is first tilted upwardly, after an American channel has been cut in the sole edge at one side of the shank, to position the English knife for cutting an English channel in the grain sideof the sole around the forepart, after which the knife carrier is tilted downwardly to reposition the knivesfor cutting an American channel in the sole edge along the opposite side of the shank portion of the sole. Also, as illustrated, provision is made for retracting the American knife from the sole when the knife carrier is tilted upwardly so that theAmerican knife will not interfere with the cutting of the English channel around the forepart of the sole and for returning the American knife into operative position when the knife carrier is tilted downwardly to resumethe cutting of an American channel in the shank of the sole. In accordance with alternative embodiments of the invention, however, the

American channel knife maybe omitted and the English knife (or a modification thereof) alone employed to out both the American and the English channels.

. already indicated it is often the custom to erfbnna shankreducing operation upon ag's'ole in order to give the appearance of a light edge in'the shank. Iti's alsethecustom with many manufacturers to" perform a feathering operation around th forepart of thesole "but in' such casesthe feathering-operation is frequently not intended primarily as a'thickness-redueing operation but is in} tended merely to flesh the surface (i."e. to remove shreds of leatherfromthe surface) without reducing'the 'thielmess er the sole to any-substantial extent.

To ada t the illustrated machine -to perform the shank reducin and fleshin operations just referred to the machine is further provided with a feather-edging knife arranged "to bevel or scarf the sole-margin at the fiesh'sidethereof, this knife being adj ustable at the will of the operator'to vary the angle ofthe bevel or: scarf produced by the knife and thereby to vary the thickness to which the edgeof' the sole is reduced. Another featureoif the invention, accordingly, is to be'recogni'zed in'th'e provision, in "a In'achi-ne for operating upon soles, of adjustable sole'edge reducing means, and mechanism for adjusting the reducing means during the operation of the machine to vary theexte'n't of sole'edge reduction independently of any variation in the thickness of the sole. As illustrated, the edge reducing means "comprise a skiving "knife mounted with provision for tilting adjustment and connected with the mechanism for tilting the channeling "knives so that when the latter are tilted to change the type of channeling the skiving knife will also be 'tilted to vary the extent of sole edge reduction. In the illustrated machine, alsogthe arrangement is such that the ski'vi'ng knife is also tilted so that, independently of the above-described tilting of theskiving knife the 'knifealso'i's tilted upon variation in the thickness'of thesole'rnarginto maintain uniform the thickness -of the sole edge produced by the edge reducing operation.

United States Letters Patent 'No. 663,050,

granted Dec. 4, 1900-, upon application of C. P. Stanbon. The illustrative-machine comprises a frame '10, a lower feed wheel 12 carried by a horizontal feed wheel'sha'ft- 14, an adjustableedgegage16 (Fig. 2) and an upper feed orpr'esser wheel 18 carried by a shaft 20 (Fig. 3) "j-ournalecl in head 22 which .is' normally" pressed downwardly against a stop 24 on the "fr a1ne 1Oarranged to prevent'thetwo feed wheels from actually engaging each other. The head 22'with the upperfeed-wh'eel-18 is adapted to'be raised by means of a treadle (not shown) to permit a soleto beinserted betweenthe feed wheels and treadle mechanism (not shown') maybe I employed for adjusting the edge gage tra-ns versely" of the direction of workfee'd while the-sole is being fed to determine the depth, and location of the channel. The abovedescribed parts, with the exception o'fth'e' edgegag'e, are of substantiallythe same construction and they are operated in the'same manner as corresponding parts disclosed in the above-mentioned Letters Patent 0. 663,050, to which reference may belied for details of construction not herein specifically described. The illustrated edge gage is is sup-portedby a slide 17 "by means otwhich channel knife while the knife l lis shaped.

like the usual sO-c'alIed American "channelknife. "In Fig. 1 thetwo knives-are shown ascdoperating in the cutting of an Ameri can channel andin' Fig. 2 the knife at ache is shown as 'op'erating independently of the knife 44 to cut an English channel. It. is to be understood, however, that, if desired, the knife 44 may be omitted-and the knife 36 only. (or preferably .a somewhat modified form of this knife such .as that shownin Figs. 8 and 9) maybe employed for thecutting of both American and English channels in the same sole. a I 1 For the purpose of enabling. the "

knives

36 and 44 to be used in the cutting of both American and English channels-Mina, sole; these knives are both supported by. a knife, carrier 28. (Figs; 1 and 2'). -of improved construction which is employed in place of-the channelknife carrier of the machine shown in the-patent referred to. The improved knife carrier 28 herein shown is formed at the lower end of a slide 30. (Fig. ,3), which is mounted for up-and-down adjustment in a guideway in the head 22, a screw 31 being providedby which this adjustment may be effected. The knife carrier 28 is provided with an arcuate guideway 32 curved about-a center indicated at 33 in Fig. 1. In the guide way 32 there is mounted for movement a knife segment 34 upon which is fixed achan nel knife 36 having its edge curved (except for a relatively short straight portion at'the tip of the knife), to form theusual Englishtype channel. Thesurfaceof the knife seg ment 34, remote from the centerof its iguideway is provided with gear teeth. 38(Fig. 1).

thatmeshwith the teeth of a toothed segmental rocker 4O fixed to a spindle42 carried by hearings on the knife carrier 28. The

above-described arrangement of parts is such that when the English channelknife .36 has been moved by rotation of the rocker 40 into its straight'tip portion lies in the path of the channel knife '44 which has' a straight blade adapted to cut an American-type channel.

In-other words when the knife 36 is posi-v tioned as shown in Fig. 1,'its tip is no longer appreciably sloped but ispractically parallel to the sole surface.

To enable the rocker 40 and the knife seg- 'ment 34 to be moved into the'two'positionsabove referred-to, the spindle 42 is extended rearwardly of the knife carrier 28 and fixed to this rearward extension is a lever arm 46;

' which isconnectedto the upperend ofa treadle rod 48. The lever arm 46 is normally held in an upwardly extending position by means of atreadle spring 50 arranged to press upwardly upon the treadlejrod 48... Up-

ward movement of the leverarm 46 (under ited by an adjustablestop 52 and downward movement of .thearm 46 (under action of thetreadle) is limited by an adjustable stop '54, the stops 5 2 .and 54 being carried by lugs.

provided with a straight guideway 58 (approximately horizontal when the lever arm 46 is in contact with the upper adjustable stop 52 as indicated in Fig. 1) in which is mounted for reciprocation, toward and from the edge of a sole positioned in the machine,

a slider '60. which carries the aforesaid straight-edged channel knife 44 adapted to co-operate withthe knife 36 in cutting an American channel. The straight guideway 58 and the edge of the straight-edged knife 44 are both parallelto the straight portion of A the edge of the curved channel knife 36. An upstanding ear 62 on the slider is pivotally connected,'by means of a link164, with one end of a lever 66 that is fixed to the front end of the spindle 42.. The arrangement is such that rotation of the segmental rocker 40 in a direction to move the English channel knife .36 to the'position shown in Fig.

1 will advance the straightrchannel knife 44.

into the path of the sole (as indicated in Fig. 1) as the knife 44 is being swung andretracted into said position by the knife segment 34 during the movement'of the latter. While manual means has been shown and described for'shifting the positions of the channeling'knives the invention is not limited to the provision of channel knife shifting means which is either wholly or partially under the control of the operator.

The aforementioned center 33 about which the arcuate guideway 32 for the knife segment 34 is curved is so located (for the particular shape ofknife herein shown) that when the English channel knife 36 is swung to position for co-operating. with the straight V knife for cutting an American channel the knife 36 is also somewhat withdrawn from the sole so that its curved portion is ineifec-- tive during the cutting ofthe American channel.'; I v The operation of theinachine thus far described is asfollowsrAn unattached. outsole A( Fig. 6) is entered between the

feed wheels

12 and 18 in'the manner usual in McKay English channel knife 36 is horizontal and the American channel knife 44'is alsoho'riportion of the Englishchannel knifeand behind it, regarded in the direction of feed (see Fig. 1) The operator starts the machine and 'zontal and is in the same plane as the straight the two knives cut an American channel (shew-1. at B, ign the shank por o o thfl 591e, the English knife cutting the marginal portion ofthe channel because it is in front (regarded in the direction of feed) of th t Part of he dge. otthe merican kn e which is carest the sole edge face (see Fig. 1). At this time the curved portion of the English knife 36 is withdrawn so that it does not cut. When the junction of the shank and fot patt rea hed. the opera-t d pr ss s the treadlc with the result that as the sole continuesits travel, the American knife 14L- is gradually withdrawn by lateral tilting movement completely from contact with the sole and the English knife 36 is gradually tilted about the center 33 and moved inward- 1y @ClgQWiSQ Of the sole so that as shown in Fig. 2 not only is the angular position of the changed but the knife is also moved sufficiently toward the middle of the sole to make the curved English channel cut shown at Gin Eig. 5. The result ofthis adjustment oft-he knife 36 isto modify theshape of the channel cutin the vicinity ofthe ball line so that when the English channel has been made at the forepart of the sole theAmerican channel B and the English channel C will be blended together. 'When the shank is reached at the other side. of the sole the treadleis released and a reverse tilting of the knife. takes place for the purpose of form: ing a blend between the English channel in the fel'epart and the American channel in the shank portion at this side of the sole.

For the purpose of reducing the thickness ofthe sole edge the illustrated machine is also prey-ided with a knife constructed and arranged to reinOYe a chip from the marginal portion of the sole (for instance from the edge of one of its faces) and provision is also made for changing the inclination of the knife during the operation of the machine. \Vhile the mechanism for effecting edge thickness reduction is herein shown in combination with channeling means it is within the scope of the invention to provide a machine adapted for reducing the thickness of the edge of a sole w thout performing any other operation time the s l As shown Fig. 4;, a bracket 71 is bolted to the frame 10 and to the upper end of the bracket is fixed a carrier 73. In order to pr y de for vertical adjustment, the carrier {Z3 connected to the bracket 71 by a tongueand-grooye connection and can be adjusted yertic ally by turning the knob 75 of a. screw 77 after which the carrier 73 may be gripped in adp sted position by tightening a bolt 79.

At the rear of the carrier 73 is a bearing for the reception of a vertical pivot-pin 81 to the upperend of which is fir-red anloscillatbracket 8?) that is provided with bearings for a l1or17ontal spindle85. To the front end of the spmdleS isfixed a knife-clamp 87 in which is secured a reducing or. feathering knife 91, the cutting edge of which lies.

behind the channeling knives.

The left-hand end (as viewed in Fig. 3) of the planeedge of the illustrated feathering knife 91 located in the line of the axis of the spindle 85, so that when the spindle is turned on its axis (as will be described later) the edge of the knife will rotate about itslefthand end. In practice'the left-hand end of the edge of the feathering knife is sometimes extended and turned down towards the feed wheel 12, or may actually extend between the adjacent rows of the teeth of the feed wheel. By raising or lowering the carrier 73 the axis of the knife-carry1ng spindle 85, and

therefore the axis of rotation of the feathering knife 91, may be correspondingly raised or lowered to facilitate adjustment of'the' knife. Further, by extending the edge of the feathering knife 91 to the left of its axis of rotation that extended part. of the knife will desired to sharpen the knifeilll the belt 95' is releasedand the oscillating bracket 83 swung in clockw se direct on to move, the knlfe 91 towards the-observer (as viewed in Fig. 4) into a position in which it can readily be removed from the'knife clampf87l In order to proride for the desire-d movement ofthe feathering knife 91 the following mechanism is provided. Fixed to the fcathering-knife carrying spindle by .an

approximately upright pivot pin is ashort" lever 101 having a ball end (Fig. 8). The ball end of the lever 101 is received in a U- shaped socket on the. endof a lever 103 that is fixed on a pivot pin 105 mounted (eccentriccally for adjustment) in a hearing in the top,

of a bracket 107 fixed to the rear of the frame 10 of the machine. The segmental rocker spindle 42 (which, as already described, is carried by the head 22) has fined to it; near its rear end, a bent lever 10 9to which is adjustably connected, by a screw llli the upper end of a link 1113; the lower end ofwhich' is pivoted to the lever 103.

It will be observed that, as a result of the above-described construction and arrangement, the feathering knife 91 will be rocked slightly about its axis of movement e., about its left-hand end in the particular construction being described) if there is a change in the thickness of the work as the latter progresses through the machine; if thework becomes thicker the upper feed or presser roll j 18 will'rise and will carry upwardly with it the left-hand end of the head 22 and consequently the spindle 42,which latter-in turn will, through the link 113, rock the lever 103 upwardly and the lever 103 will,through the lever 101, rock the feathering knife 91 to increase the amount of edgethickness reduction. The various parts are so proportioned,

connected and adjusted that, unless manually moved as will be described hereinafter, the

feathering knife will always reduce the edge of the workto a definlte uniform thickness It will further be observed that if the spindle42 be oscillated (as occurs under ac l]l0110f the treadlemechanism in changing from an American to an English channel and vice versa) tlllSWlll also cause a rocking of nessof the edge of the work (little more ina the feathering knife; the construction and arrangement arej such' as to give around the fore-part, in Conjunction with the English channel, a very small reduction in the thick- .deed than suihcient to remove projecting shreds of, leather) and to give at the shank. n conjunction with theAmerican channel, an appreciable reduction in the thickness ofthe edge of the work so as to produce there a so-called. light .or thin edge shank, Thus, through the action of the treadle mechanism above referredto. the angle of the feathering knife may be adjusted by the operator to vary the amount ofsole'edge reduction while the machine is running at normal speed. In Figs. 5 and 6 the parts of the sole indicated by dotted lines and marked D and E are the chips or trimmings that are removed from the forepart andthe shank respectively by the use of a particular feathen ing knife adjusted in a particular way (the effective left-hand end of thecutting edge of the feather knife being in l ne with its axis of rotation) in the illustrative machne.

Many manufacturers desire a wide and shallow feathering scarf round the forepart of the sole (as the scarf D, Fig. 5) and a narrow [and deep scarf in the waist, this latter scarf being as deep as or deeper than the scarf .E 1n F g. 6, and about-half or less than half the width of that scarf. Such a result can be obtained by the use of a feathering knife that extends about equally on each side of its'axis of rotation (the cutting edge of the knife passing through the line of the said axis), by adjusting the carrier 73. so that the said axis isslightly below the level of the top of the feed wheel 5 (i; e. belowthe bottom surface of the sole to be feathered), and by ferred to is indicated in Fig. 3 by the dotted lines 7 6 in conjunction with the full lines of the knife. 91. I r i i It is to be observed that the carrier 73 can be raised or lowered to bring the axis of rotation of the feathering knife on, above or below the level of the feed wheel 12 (i. e. ofthe bottom of the work); that there may be used a feathering knife of such a width that the left-hand end of its edge may extend (laterally of themachin'e) to, short of, orb'eyond its axis of rotation; that the aforementioned edge gage can be adjusted laterally of the machine to vary the position in the machine of the edge of the work; and that by adjusting the screw 93 the operative position of the feathering knife about its pivot 81 may be varied. Bymeans of these adjustments a considerable variation in edge-thickcan be obtained by suitable variation of these variables.

If it be desired to provide for grooving in addition to channeling this can readily be done in the illustrative machine. One'convenientconstruction providing for waist grooving is indicated in Fig. 7. The shank 121 of the American channel knife 44 is provided at its rear with a horizontal recess 123 for the reception of the shank 133 of a grooving knife 131 which is semi-circular in shape, the upper edges of the grooving knife being ona level with the cutting edge of the American channeling knife 44. The groovingknife 131 is located behind and as close as possible to the knife 1 1. With the construction and" arrangement indicated a groove is cut at the base of the American channel. 1 The grooving knife is of course withdrawn along with the American channel knife.

It may be of advantage to give the channeling knives a rapid reciprocatory or jogging movement of small amplitude, in the line of work feed, in order to assist in the cutting of the channel especially if there be,

channeled sole by the use of two knives a somewhat similar result may be obtained by the use of one knife only as will now be described. For this purpose a knife such as that shown at 360 in Figs. 8 and 9 may be employed,the knife 360 beinga compromise between the usual English and the usual American channel knife. As shown, the knife 360 iscurved in a curve of large radius throughout ,or practically throughout its length, the part adjacent to its point being perhaps more nearly straight than the rest of the knife. This knife is mounted in a slide movable in an are as already described so-that inone position it will cut a rather unusually flattened English channel and in a second position will cut a channel of the American type although somewhat curved instead of straight. When putinto this second positionthe knife may (eg. by suitable disposition of the center of the are) also have its point moved somewhat toward the median line of the sole so that it will out an American channel the base of which is further from the edge ofthe sole thanis. thebase of the English channel which it, cuts in its other position. Such a knife position changing mechanism may be controlled manually or automatically as may be desired.

Another single-knife construction for channeling is illustrated in Fig.11, in this case also the one knife 440 being a compromise. The greater part of the edge of the knife 440 is straight like an American channel knife but the right-hand end is curved as shown at 4&2 into the English shape to adapt it to cut through the grain surface of the sole. The edge guide l6is so adjusted that when it is pressed to the left to the fullest extent (as it is normally) the sole will be held in such a position that the straight part only of the knife will be active to cut the sole and therefore an American channel will be cut (in thewaist), When the forepart is reached the edge guide 16 is moved (as by treadle mechanism hereinbefore mentioned) to the right to a predetermined extent and consequently the sole, being pushed to the right 3 toifollow it, is as it were pushed further on to the knife so that the curved part 442 of the knife also is active and an English channel is out. It will be observed, however, that in this case the English channel is deeper than the American channel. With this construction the hereinbefore described rocking feathering knife may readily be used by coupling it to the edge guide treadle.

An alternative mechanism according to the invention admitting of obtaining with one knife two different shapes of channel at different parts of the one sole will now be described with reference to the diagram of Fig. 10. In this case the knife 450 is a straight-edged channel knife of the usual American type adapted to cut an American channel as usual in the type of machine re- 1 fer-red to. The machine is provided, however (in addition to the usual feed wheel 12 and presser roll 18), with'an auxiliary presser roll 180 adapted to act when desiredon the grain surface of the sole margin and shaped to bend that margin in a curve in such a way that the knife 450 will then cut into the bent sole from the grain surface insteadof from the edge and will cut a channel which when the sole margin is agam straightened appears be thrown into action manually or automatically whenever it is desired to out such an English channel.

, Conveniently the auxiliary presser rol'l 180,

when depressed to act upon the work, is de-. 70

.p-ressed positively to a predetermined level,

notin action lock-ed in position with its upper surface at the level of and forming a lateral extension of the feed wheel 12. 230
