SOLEfFITTING MACHINE.

Application led September 26, 1924. Serial No.. 740,100.

In machines of the general type above referred to the lower feedy Wheel supports the` work and is immovable vertically, the upper feed Wheel, together Awith a channel knife and a grooving knife, are adapted to :nove up and down in accordance with variations in the thickness of the work; and the width of the channel is gaged by anedge `"ell which is mounted tien to the lower feed roll and is usually geared tothe latter so as to be` driven thereby at the same peripheral speed to assist in In order that the chan-y feeding the work. j nel knife may be capable of adjustment into position to cut a channel extending in a Widthwise direction toV the edge' face of a sole, the edge roll must be located so` that the cutting edge of the channel knife `will slightly overlap the upper end face of the edge roll and therefore the edge roll can project above the lower feed roll no ymore than permitted by the channel knife when the latter is adjusted vertically for the thinnestsole which the machine is adapted to operate upon. Consequently although the edge roll Will be capable of engaging a thin sole throughout substantially -the full Width of the edge face ofi the :foie it Willcngage only the loiverrportion of the edge face of a relatively thick sole. A thick sole therefore may be inadequatelysupported against the thrust exerted by the operaterin holdingthe sole against the edge roll,` iviththe result that the outer edge of the channel is liable to beV uneven and ragged. In some cai-ees, the material of the sole adjacent to the upper portion of the crowded somewhatl over the upper surface and i in lined vertical rela-` sole edge may be of the edge roll, or the margin of the sole may even force its Way into the space between thc channel knife and the edge roll to such an extent as to interfere with the feed ofthe sole. j

One object of the present invention is to overcome the Vdifficulties above mentioned and to this end a feature of the invention consists in the combination, With a Work support and a channel knife movable relatively to the Work support and in response to variations in the thickness of the Work, of a yieldingly supported edge gage, and means movable in unison with the knife for determining the relative positions of the knife and the edge gage.V In the illustrated embodiment of the invention, the lower feed roll is mounted upon `a stationary frame, the upper feedl roll is carried by ahead which is pivoted'upon the frame for 11p-anddown adjustment relatively thereto, the edge roll is supported by the stationary frame and driven through connections with the lower feed roll constructed and arranged to permit the edge roll to rise and fall with the head, and yielding means is Vprovided `for holding the edge roll continuouslyin cngagement with a portion of the head so that it will partake of the up-and-down movement thereof. Such an organization enables the edge roll and the cutting means relatively to be adjusted in the desired intimate relation necessary to secure clean cutting operations and continuously to be main-y tained `in such relation irrespective of variations in the thickness of the Work. As a result, the edge roll will engage theA sole throughout substantially the full Width of the sole edge veven upon the thickest. sole. The Work will therefore be adequately supported against the edgewise thrust exerted by the operator and a clean Acut channel clear to the extreme edge of tbe sole will be insured whenever desired. t

In machines of the type`above referred to, as heretofore constructed, 'angular adjustment of the channel knife has been secured by loosening the means which clamps the knife to the knife block and shifting the knife angularly relatively to the knife block. Such procedure, however, is liable to disturb the vertical or horizontal adjustment of the cutting edge of the channel knife relatively to the cutting edge of the grooving knife so thatthe groove may not be cut to the desired depth or located accurately with respect to the channel out. The proper relative horizontal and vertical adjustment of the channel and grooving knives is usually effect-cd only after more or less experimenting and careful manipulation on the part of the operator, and once such an adjustment is properly made, it is desirable that it shall not be disturbed by subsequent changes in the angular adjustment of the channel knife tending to result in variation in the depth or location of the groove.

To avoid the above-mentioned disadvan tages resulting from the customary manner of angularly adjusting the channel knife, and to insure that the free extremity of the cutting edge of the channel knife shall be reta-ined inthe same relation to the cutting edgeof the grooving knife irrespective of variation in the angular adjustment of the channel knife, another feature of the pres.` ent invention consists in the combination with a. grooving knife, of a channel knife guided for angular or tilt-ing adjustment about an axis which may be made coincident with or closely adjacent to the axis of the grooving knife.

Other features of the invention relate to the provision of a reorganized channeling machine of the above-mentioned type embodying certain improvements in the form and arrangement of the knife carriers whereby various vadjustments of the channel and grooving knives may conveniently be effected; to the .provision of improved means for detachably securingr the knife-carrying head to the frame of the machine; to the provision of simple and convenient means for adjusting the knife-carrying head transversely of the direction of work feed which may be set to secure an accurate predetermined adjustment of the width of the chan `nel and which 'will not interfere with the removal of the head from the machine; and

Vto a machine organization constructed and arranged to facilitate the manual control andadjustment of various operations of the machine.

The invention further consists `in'features of construction and combinations and arrangements of parts hereinafter described and claimed.

Referring to the dra-wings, the instrumentalities which operate upon the work coniprise al lower feed wheel Q0 (Fig. 1) a rotary edge gage or edge roll 22 wheel 24, a presser foot 26. a` channel knife 28 and a grooving knife 30 (Fig. 3). The lower feed wheel and the edge roll are mounted upon a lower or main frame 32 (Fig. 1), while the upper feedrwheel, thc presser foot and the knives are supported by an upper frame or head 34 which is detachably mounted upon .the main frame with provision Vfor a limited amount of up-anddown swinging movement relatively thereto and also for horizontal adjustment transversely of the direction of work feed. The main frame 32 is formed with a depending cylindrical post 36 which is received within a hollow pedestal 38 adapted to be bolted to a bench or other support. The upper portion of the pedestal 38 is split vertically an upper feed lll) post 36 by means of a collar screw 40 so that .ill

the frame 32 may be secured in any desired position of adjustment about the axis of the pedestal.

The lower feed wheel is rigidly secured to the outer end ot1 a horizontal shaft 42 which is journaled in suitable bearings in the main frame. The upper feed wheel 24 is carried at the outerend ot a horizontal shaft 44 which is journaled in bearings formed in the head 34 and is adapted to be driven from the lower feed wheel shaft 42 through

intermeshing gears

46 and 48 on the

shafts

42 and 44 respectively. The gear 46 also meshes with a pinion 5() fast on a main shat't 52 which is j'ournaled in bearings in the frame 32 and derives its motion ntrom a pulley 54 which is rotatably and slida-bly mounted on said shaft and is adapted to be connected by means of a belt 56 with any suitable source of ower.

he pulley 54 is adapted to be connected with the main Shaft 52 through 'a friction clutch comprising an annular driving clutch member 58 formed on the outer side of the pulley 54 and having a smooth lateral tace arranged to cooperate with a driven clutch member in the form of al friction ring 6() txedly secured to the inner side of a hand wheel 62 which is keyed tothe main shaft and is retained in place by means ot' locknuts '64.

The pulley carrying the driving clutch member 58 is adapted to be shifted bodily toward the hand wheel 62 so as to engage the members of the friction clutch and thereby connect the main shaft with power by means of a wedge block 66 which is slotted to receive the shaft and is connected, through a rod 67, with a foot treadle 68 (Fig. 11) normall heldin. elevated position by means of a suitably arranged spring 69. The inclined face of the wedge block 66 cooperates with a similar inclined wedge face formed on a collar 70 slidably mounted on the main shaft- 52 between the wedge block and the pulley, the collar being formed with a depending portion carrying laterally offset lugs 72 which straddle "the lower portion of the wedge block to prevent the collar from turning with the shaft and pulley. lith the above described construction. as long as the treadle 68 is held depressed, the driving clutch member 58 will be held `contact with the friction ring 60 and the main shatt `will be rotated under power, but when the treadle is released the 'ulley 54 will turn idly upon the `driving s aft.. Upon release ot the foot treadle, the hand 'wheel 62 may be used as a brake to reduce or arrest the speed of the machine. In practice. it is found con` venient for the operator to thus slow up the machine while operating around Vthe toe or other abruptly curved portion of the margin of a sole.

Under certain conditions, itis desirable to have themachine run continuously and in vorder that thisresultmay be obtained without it being necessary for the operator to hold the treadle 68 depressed, a latch device is provided for holding the wedge block 66 in its lowered position. The arrangement is such that normally-the latch device is maintained inoperative, but it is capable of being set so that it will become operative, either upon the depression ofthe it'oot treadle which actua-tes the wedge block, or upon the depression of a conveniently llocated hand lever 74. To this end the hand lever 74 is pivoted at 76 to an adjustable post 78 carried by the pedestal 38 and is connected by means of a spring 80 with a pin 82 projecting from the pedestal 38. The hand lever 74 is longitudinally slotted at 84 and is bored in a direction at right angles to the length of the slot 84 to provide apertures 86 through which the treadle rod 67 extends loosely. A collar 88, rigidly7 secured to the treadle rod 67, is receivedv within the slot 84, thus connecting the treadle rod with the hand lever 74 so that depressionof the latter will operate to throw the clutch. To latch the wedge block 66 in its lower position so as to hold the clutch members engaged, a latch 90 is pivoted at 92 upon the hand lever 74, the latch being `notched `at its 'upper extremity to provide shoulders for engaging the pin 82. The latch 90 is yieldingly `held in engagement with the pin 82 by means of the spring 94 confined between the hand lever 74 and a thumb piece 96 projecting from the latch 90. Upon depression of the hand lever 74 from the position shown by dotted lines to the position shown in full lines in Fig. 12? the spring 94 functions to throw the latch 70 into cooperative engagement with the pin 82, thus latching the lever 74, together with the treadle rod 67 and the wedgeblock 66, in their lowered positions and holding the clutch members engaged. By depressing the thumb piece 96 the latch 90 may be readilyl released for the purpose of disengaging the clutch members. In order that the latch 90 shall not function` except when desired, to maintain engagement of the clutch members, a pawl 98 is pivoted at 100 to the hand lever 74 and is adapted normally to engage an inclined shoulder 102 formed on the latch 90, this inactive posit-ion of the pawl 98 being shown by dotted lines in Fig-12. `Below the shoulder 102, the latch 90 is notched, as indicated at 104, and by swinging the pawl 98 downwardly away from the shoulder 102 and into the notch 104, the spring 94 is enabled to swing the latch into operative position upon depression of the hand lever 74 or the foot treadle 67.A To prevent upward movement of the pawll 98 beyond the dotted line position a lug 101 is formed on the pawl to engage the opposite side ofthe latch from that engaged by the main portion of the viewed in Fig. 1) is loosely pivoted tothe slot 156. is formed in the head 34 to receiveV a roller 158 carried at the outer end of a horizontal ystud 160. The stud 160 is supported by an arm 162 (Fig. 3) fixedly secured to the upper extremity of a post 164 which is slidable vertically in the frame 32.

In order that the head 34 may be easily and quickly removed from the frame 32, the stud 160 is arranged so that it may be readily withdrawn from the slot 156. To this end, the stud 160 is detachably secured to theblock 162 by means of a pin 166- which extends 'freely through the block 162, trans-v versely semi-cylindrical notch 168 (Fig. 2) in its side, the notch being adapted to receive the stud 160. rlhe upper end of the locking pin 166 is threaded to receive a wing nut 170 which, when tightened, causes one side of the notch 168 to clamp the stud 166. The stud 160 extendsoutwardly beyond the block 162 and is knurled at 172 to `facilitate' its removal.

The use of a locking pin of the character just described is advantageous since it arl'- iords a means for securely locking a smoothly iinished cylindrical member without possibility of injuring the iniShedsurace thereof. The locking devices, 134 4and 1367 hereinbefore 1nentioned,`1nay comprise pins termed with cylindrical notches, such as the notch 168, to receive the slide 124 and the post 122, respectively, and said pins ma be provided with suitable nuts arrange to draw the pins into clamping positions.

The post.` 164, which carriesV the sup orting block 162 and the stud 160, is sli able vertically in bearings 174 on the main frame and a'spring 176 encircles the post 164, be-

tween the upper bearings 174 and acollarl 178 threaded upon the post, the Aforce of the spring acting through the block 162 and the roller 158'to force the unpivoted end of the head 34downwardly to hold the knives in4 the work. In order toinove the operating instruinentalities carried by the head 34v away from the lowei` feed roll to facilitate the introduction and removal of thework, the head 34 is adapted to be raised against the action of the spring 176'by means of a foot treadle 180 (Fig. 11) and a treadle rod 182 (see also Fig. 1) the rod 182 being alined with the post 164 and abutting the lower end thereof. The treadle 180 is pivoted at 184 to a oorbracket 186 and a spring 188 is arranged to return the treadle to raised or in active position.

The downward swinging movement of the head 34 is limited bymeans of a stop screw of the stud 160, and is formed with aV 190 threaded at 192 into the upper bearing 17 4. The stop screw 190 is formed with an enlarged central portion 194 which is receivedin the counterbored lower portion ot' an aperture 196 in the supporting block 162. The reduced upper portion or' the stop screw 190 extends freely through the aperture 196,' and above the block 162 the stop screw is provided with a square head adapted to receive a; wrench by means of which it may be turned to vary the elevation of the stop shoulder 194 and thus to vary the vertical adjustment oi' the head 34. Below the threaded portion of the stop screw 190 a reduced extension 198 projects beyondV the lower side `of the bearing 174 and a lock-nut 200l on saidextension is arranged to. secure the stop vscrew 190 in adjusted position. An auxiliary stop screw 202, carried by the frame 32, insures against thepossibility of the knives coming in contact with the `toothed lower feed wheel 20 on account of `improper adjustment of the stop screw 190. The head 34 is guided in its vertical swing` ing movement between spaced wings one of which is shown at 204, these wings rising from the frame and engaging finished bearing surfaces at opposite sides of the head. The

gears

46 and 48 being located closely adjacent to the pivot pin 152 will not become disengaged troni one another by the upward swinging movement of the head. The holddown eti'ect ot' the sprin 176 is particularly edective inasmuch as t e force ot' the spring isapplied through the roller 158 at a point remote from the pivot pin 152 and near the operating instrunientalities.

'lhe abovedescribed horizontal slots 154 `and 156 permit adjustment of the 4head transversely of the direction of workfeed so as to position the knives relatively to the solo edge so that a wide or narrow shoulder may be .formed between the channel and the edge ot the sole, or, if desired, the channel may be made to extend to the edge face of the sole, either at the upper corner thereof, or to a line below said corner. To eiect such transverse adjustment of the head 34, an adjusting sleeve 206, (Fig. 9) is employed, the sleeve having an eccentric 208 formed thereon for engagement with the opposite curved sides of a slot 210 in the head. As shown, the adjusting sleeve 206 is mounted to turn on a fixed stud 212 projecting from the frame 32 and a lnurled head 214 is provided forturning the sleeve. The opposite` curved sides of the slot 210 are struck from a center in the axis ofthe pivot stud 152 and the slot is open at its lower end to enable the head 34 to be readily detached from the frame, `32. A lock-*nut 216 on the stud 212 is adapted` to bind the sleeve 206 against the frame 32 to secure the sleeve and the head 34 in adjusted position. As shown .in Fig. 9, suitable graduations may be provided upon site directions so that when the head 214, and a suitable cooperating mark upon an adjacent portion of the frame 32 lto assist in the transverse adjustment of the head. Y

The upper feed roll 24l is keyed to the outer extremity of the shaft 44 and 1s retained against axial movement between the end face by a bearing 218 on the head and a collar 220 secured by means of a screw to the end of the shaft 44. The presser foot- 26 is fixedly secured by means of a screw 222 to the side of the bearing 218, the screw 222 extending through a longitudinal slot 224 in the shank of the presser foot to permit vertical adjustn'ient of the presser foot. i As shown, the upper feed wheel 24 and the presser foot 26 are located side-by-side above the lower feed wheel 20 and said feed wheels cooperate in the usual manner to feed the' Work, while the presser foot performs its usual function of gaging the depth of the cuts made by the knives. In addition, the presser foot assists the upper feed roll to hold the workagainst the lower feed roll. It will be seen that the upper feed wheel is offset outwardly relatively to the lower feed wheelV and that the lowermost point in the periphery of the upper feed wheel lies substantially in the horizontal plane of the pivoted axis of the head. In order to insure Contact of the upper feed wheel roll with the work throughout the entire'width of the roll, irrespective of the angulaiadjustment of the head 34 about its pivotal axis, the periphery of the roll 24 is slightly tapered axially, the diameter of the outer edge of its periphery being greater than the diameter of the inner edge thereof, so that when the head is swung upwardly to accommodate a thickerl portion in the work, the outer edge of the feed roll will not be lifted out of feeding engagement with the work.

The channel knife 28 is formed with a. rectangular shank 228 and with a laterally offset blade provided with a cutting edge at each end of the shank. The channel knife is made with two cutting edges so that when one edge has become dull a sharp cutting edge will be immediately available and may be quickly placed in position by reversing the knife end-for-end relatively tothe block to which the knife is removably secured. The two blades are laterally offset in oppothe knife is se! cured in place one blade will project downwardly and the other blade will project upwardly with respect to the shank of the knife. This construction insures that the inactive 'or reserve blade will be located out of the way where it will not be liable to be damaged or to interfere with the action of any of theoperatingparts of the machine. As shown in 5, the heel or rear portion of each blade of the channel knife is notched at 229 to enable the cutting edge of the the knife by a collar screw 237, said screw extending through the knife block 230 and being threaded into the clamp plate. Cooperating bevel faces 232 and 234 on the clamp plate 236 and the knife block 230 hold the' shank of the knife seated against the ,'

aces

232 and 234 on the knife block. The knife block 230 has a horizontal tongue-andgroove connection 238 with a knife block holder 240 which permits adjustments of the knife relatively to the presser foot and feed wheels in the direction of feed. The knife block is adapted to be clamped in adjusted position upon the knife block holder 240 by means of a collar screw 242 which extends through a slot 244 in the knife block and threaded into the knife block holder.

To facilitate angular adjustmentl of the channel knife, lthe knife block holder 240 is formed with a segmental face 241 arranged for sliding adjustment along a corresponding segmental face on the lower portion of a vertical vslide or carrier 245, an arcuate tongue-and-groove connection 243 being rovided between the holder 240 and the sfide. The cooperating segmental faces and tongueand-groove connections between the knife block holder and the knife slide are curved about a center so arranged that the point of the channel knife, or the point of the grooving knife, or the points of both said knives may be made to coincidesubstantially therewith as may be desired. The lower portion of the slide 245 is split lengthwise of the tongue-and-groove connections 243, as shown at 246, andthe split portions of the slide are adapted to be contracted by means of a collar screw 248 to secure the knife block holder 240 in its angularly adjusted position. As shown in Fig. 1, a suitable mark upon the side of the knife block holder 24() may be arranged to cooperate with the graduations of a scale 249 on the. lower portion of the channel knife slide 245 to enable the channel knife tobe ,set to cut a channel at a predetermined angle with respect to the face of the sole. vBy providing theabove described segmental tongueand-groove mounting for the channel knife block holder, any desired angular or tilting adjustment of the channel knife may be conveniently obtained and the angular adjustment of the channel knife may be changed at will without disturbing the adjustment of the channel knife relatively to the knife liz ing formed by a removable plate 252. The

slide 245 is supported in the guideway 250 by means of a rod 254 pinned at its lower extremity to the slide and passing througl'i an apertured ear 256 on the head, the upper end of the rod 254 being threaded to receive an adjusting nut. 258 which bears againstA the upper side of the ear 256 and constitutes a stop to limit` the downward movement of the channel knife slide as wellas a means for adjusting the channel knife vertically relatively to the grooving knife and the upper feed wheel. The channel knife slide is pressed downwardly by means of a spring 260 which encircles the rod 254 between the upper `end of the. slide and the ear 256. lock-nut 262 is arranged to prevent accidental displacement of the adjusting nut 258.

As shown in Figs. 6 and 7, the channel knife block 230 is formed with a fiat lower face 263 of an area sufficiently large toY cover substantially the entire upper surface of the edge roll'22. Vith this construction it has been foundthat there is notendency for the edge roll to cramp or bind upon the pins 142 or the post 122 as -a result of the very slight tilting movement of the head in response to.

variations in the thickness of thework.

The grooving knife 30 is of the usual tubular construction and is carried at one end on a rectangular shank 264 which is adjustably held by a clamp plate V265 and a collar screw 266 against perpendicularly disposed locating shoulders formed in a knife block 268. The knife block 268 is formed with a laterally offset lug 267 having a horizontal rongue-and-groove connection 269 with a knife blockholder 270 yto which it isclamped by a collar screw 272, `said screw extending through a" slotI 274 in the knife block and being threaded into the knife block holder. The tongue-andgroove connection 269 permits adjustment of the grooving knife relatively to thechannel knife in the direction ef feed, This adjustment may conveniently be made yby means ofL a wrench inserted thipugh one ofl the perforations 275 in the upper feed wheel. The knife block holder 27 O has a. horizontal tongue-and-groove connection 276 witha vertically movableslide or carrier 27 7 and a collar screw 278 which extends through a slot286 in the knife block holder 270, is threaded into the slide 277 to secure the holder in adjusted position relalmovement of the slide.

tively to the slide. As shown, the tongueand-groove connection 276 lextends longitudinally at right angles to the connection 269 between the knife block and the knife block holder, thus permitting adjustment 4of the grooving knife either with or relatively to the `channel knife in a direction transversely of the direction of work feed. By means of this arrangement the depth of the channel and the distance between the groove and the edge of the sole may be adjusted independently of each other to vary the relation between these dimensions, or either maybe adjusted to compensate for a change in the adjustmentof the other soras to maint-ain a constant relation between the dept-h of the channel and the distance between the groove and the sole edge.

The grooving knife slide 277 is held by a removable plate 282 in a guideway 284 `in the head 34 and the slide pressed downwardly by a spring 286 located between the slide and a lug 288 on the head. The spring 286 encircles an adjusting screw 290` having a knurled head 2.92 and a shank the lower portion of which is threaded into the knife slide .277.while the upper portion of the screw shank extends freely through the lug 288. "A stop collar 29st on the shank of the adj ust ing screw 290 is received in a recess 296 in the lug 288, the recess being shaped to permit upward movement of the slide 277 relatively to the head'under theinfiuence of the spring 286, so that the growing knife may be lifted out of the work independently'of the channel knife-for reasons well known in the arl". rlhe shoulder formed at the lower extremity of the recess 296 limits the downward movement of the grooving knife slide,

,while the shoulder formed at the upper extremity of said recess limits the upward screw 290 by means of the knurled head 292, the normal vertical position of the slide 27 7 relatively to the head 34 may be adjusted to vary the depth of the groove in the work. In order that the screw 290 may be prevented from turning after it has been adjusted, a tail 298 at the lower end of the screw extends through a semi-circular notch 800 in a locking pin 302 which extends freely through the slide 277 at right angles to the screw 29() and through a vertical slot 304 in the plate 282. A wing Vnut 306 threaded on the outer end of the pin'302 may be turned to draw the pin outwardly so that the tail of the screw 29() will be tightly clamped by one side of the notch 300. The vertical slot 304 permits upward movement of the slide 277. i

It is sometimes desirable to cut a channel along certain parts of the sole margin, e.

around the toe, without also cutting. t e groove in the channel'. To enable this result to be accomplished provision is made for By turning thelifting the grooving knife independently of the channel knife. To this end, a lever 310 is pivoted at 312 to the head 34 and the short arm of the lever engages beneath the knurled head of the screw 290. The long arm of the lever 310 is dctacliably connected at a point near the pivotal axis of the head with a treadle rod 314 which, in turn, is connected with a foot tre-.idle 2316 (Fig. 11). The ireadle 31o is adapted to be depressed to raise the grooving knife slide 277 so as to lift the grooving knife out of the work. A spi'ing 318 arranged to return the foot treadle 316 to inactive position. Fig. 13 shows a portion of the toe of a sole which has been prepared by a machine embodying the present invention and in which both the channel 320 and the' groove 322 are continuous around the toe.v Fig. 1l illustrates the result of raising the grooving knife independently of the channel knife by means of the treadle 316, the groove 322 in this tigiire being omitted around the toe.

lt is sometimes desirable to cull parallel grooves instead of a single groove in the channeled portion of the sole and for this purpose, an additional (Fig. 4) may be employed. As shown, this grooving knife 321 is formed with a shank Y ortion 326 and the oroovine' knife block 26S .may be formed with an extension 328 grooved as shown at 33() to receive the shank 326 of the additional grooviiig knife 324. The grooving knife 324 is secured in place on the extension 32S of the grooving knife block by means of a clamp plate 332 and a collar` screw 334 which extends through the clamp plate and is threaded into the extcsion of the knife block. The collar screw may be loosened to en'able the grooving knife to be adjusted vertically relatively to the grooving knife 30. By loosening the screw 266, a relative adjustment of the grooving knives 3() and 324 toward or from each other transversely of the direction of work feed may be readily effected. Fig. 15 shows a portion of a hanneled sole in which parallel grooves 336 have been cut by means ofthe knives 30 and i524, and Fig. 1G is a similar view showing a portion of a sole in which parallel grooves terminate short of the toe end of the sole.

It will be seen from the foregoing descrip` tion that the illustrated machine embodies various improvements in the form and arrangement of the devices for support-ing the channel and grooving knives whereby these knives` may be adjusted each independently of the other horizontally, both in the direction of work feed and transversely thereof, as well as vertically relatively .to the swinging head 31. The presser foot 36 is also adjustable verticall i with respect to the head and the knives. he channel knife, in addition to being adjustable both vertically grooving knife $241.

and horizontally as described,`is capable of being adjusted angularly in a vertical plane transverse'. to the direction of work feed without disturbing the vertical and horizontal adjustment of the knife relatively to the other operative parts of the machine. Thus it is unnecessary for the operator carefully to readjust the channel knife horizontally and vertically after a suitable angularadjust-ment has been secured and consequently a considerable saving of time is effected whenever the angular adjustment of the knife is changed. The construction of the parts supporting the channel knife is such that a suitable scale may beemployed, as described, for determining the angular ad justinent of the channel knife in accordance with the angle at which it is desired to cut the channel. The channel and grooving knives are adjust-able in unison transversely of the direction of work feed and relatively to the edge roll to vary the distance between the channel and the edge of the sole. The eccentric adjusting sleeve 206, which is turned by means of ,the knurled head 214 conveniently located at the side of the machine, provides for a very line and accurate adjustment of the knife-carrying head 34 transversely ofthe direction of work feed. The eccentric sleeve 206 mayconveniently be locked against turning to secure the head 231 in adjusted position. The scale upon the periphery of the knurled head 214 enables the channel knife to be adjusted so that a. shoulder of a desired width may be obtained between the channel and the sole edge and the construction is such that the setting of the eccentric sleeve is not disturbed by the removal of the head from the machine. The head 34 may be quickly and easily removed from the frame to afford access to various parts of the mechanism for the purpose of making repairs and various adjustments, such, Vfor example, as the reversal of the channel knife. To remove the head 34, it is necessary only to loosen the wing nut 170 and Withdiaw the stud 160 from the slot 156. Thereafter the head may be disengaged from the frame 32 by an upward movement without it being necessary to manipulate any of the connections between the head and the frame.
