MACHINE FOR USE IN MAKING SHOES.

Application filed November 10, 1917, Serial No. 201,211. Renewed June 2, 1922. Serial No. 565,386.

To all whom it may concern:

Be it known that I, F REDERIO E. BERT- RAND, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Use in Making Shoes; and I do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertuins to make and use the same.

This invention relates to machines for use in the manufacture of boots and shoes, and

is illustrated as embodied in a channeling machine for fitting soles to be used in such manufacture. I

Objects oi the invention are to improve the construction of machines of this character to facilitate their conversion for diilerent classes of work, to provide an improved adjustment for the channel knife; to simplify the feed mechanism to permit operation at a hi her speed, to prevent operation of the machine where no work is present, and to improve the operation if the machine in other respects as will be explained.

To facilitate conversion of the machine, as when changing from welt to. turn work or vice versa, novel means is provided for gaging the edge cut from the top of the sole under control of a presser foot (for welt work), or alternatively for gaging the edge cut from the bottom of the sole or from the work support (for turn work). To facilitate this conversion, an improved construction is provided including a yieldingly-mounted slide carrying a presser-ioot (and also, as will explained, preferably having a knife clatoipcd thereon), a second slide for the edge-knife, and means for connecting and disconnecting the two slides.

To provide a quick adjustment for the channel knife, as is especially desirable in a machine which is thus convertible and as is of utility in channeling machines of other types, the knife carrier is constructed and arranged for movement to tilt the channel lead of the knife and the width of the between substance formed thereby.

In the preferred embodiment of my invention, the channeling and feeding means includes a device, carrying an intermittently-eii'ective sole-engaging foot, which is mounted for oscillation in a vertical plane about a horizontal axis below the work-support. This not only admits of a very compact and efficient construction, but clears away much of the drive mechanism which overhangs the work-support of previous machines, obstructing the operators view of the work. I provide operator-controlled means for varying the amplitude of oscillation of this device, to vary the rate at which the work is, fed, and in the illustrated ma-' chine a novel work-support is provided which includes a sole-engaging member which is reciprocated with the feed foot to co-operate therewith in feeding the work.

To prevent the-machine from running idle, improved operating and feeding mechanism is provided, including means to prevent the starting of the machine until a new piece of work is inserted, and means for stopping said mechanism when a finished piece of work is removed. I

The above and other features of the preferred form of the invention are illustrated in the accompanying drawings, in which Figure 1 is a front elevation of the working head of a channeling machine; Fig. 2 is a plan, Fig. 3 a left end elevation, and Fig. i a rear elevation 01"" the machine head shown in Fig. 1; Fig 5 is a plan View, partly in section, showing more particularly the improveddriving mechanism; Fig. 6 is a vertical, sectional view of the machine head taken on the line 6-6 of Fig. 2; Fig. 7 is a vertical, sectional view taken on the line '('7 of Fig. 1; Fig. 8 is a vertical, sectional view taken on-the line 8-8 of Fig. 4; Fig. 9 is a plan view on an enlarged scale partly in section, taken on a plane just above the sole supporting table, showing the relation of the sole-engaging tools; Fig. 10 is an enlarged front elevation showing the improved mounting and arrangement of the tools in detail; Fig 11 is a detail view, in side elevation, of the channel knife block; Fig. 12 is a view of the channel knife block looking from the right in Fig. 11; and Fig. 13 is a detail view, in side elevation, showing the mechanism for connecting the edge gage with the operating lever of the driving mechanism.

In the illustrated embodiment of the invention the machine is shown as adapted and equipped for channeling turn soles. Referring first more particularly to Figs. 1, 3, 6, 9 and 10, the sole S (Fig. 10) is supported upon a table and is fed pasta channel knife 22, and edge knife 24, and a shoulder knife 26, the position of the edge of the sole relative to said knives being determined by an edge gage 28. The depth of the channel cut is gaged by a channel presser-foot or gage 30, the depth of the shoulder cut is gaged by an edge presser-foot or gage 32, and the depth of the edge cut is gaged from the top of the table. The channel presser-gage holds the sole upon the table in advance of the channel knife in the line of feed, and the edge pressure-gage operates in a similar location with relation to both the shoulder and edge knives, although it gages the depth of the cut of the shoulder knife only.

The channel knife 22 is mounted for angular adjustment about an axis passing through the end of its cutting edge in order that the angle of the channel cut may be varied Without affecting the width of the between substance or the de 3th of the channel. The knife is secured in a knife holder 34 (Figs. 11 and 12) by a clamping plate 35 and a cap screw 37. The holder 34 is secured in adjusted position on a knife block by the overlapping head of a screw 39 and a screw 41 passing through an arcuate slot in the knife block and threaded into the holder 34. An arcuate tongue and groove connection between the holder and the block per mits radial adjustment of the knife about a center at its cutting point by loosening the screws 39 and 41. By loosening the screw 37 the knife may be removed for sharpening and replaced without disturbing its angular adjustment. The knife block has a dove tailed connection (Fig. 8) with the lower end of a channel knife slide 38 (Fig. 6) through which it may be adjusted toward and from the edge knife to vary the width of the between substance, and it may be locked in adjusted position by means of a bolt 40 threaded into the split lower end of the slide. The channel knife slide 38 is vertically movable in a channel-shaped carrier 42 (Figs. 3, 4 and 6) which is mounted for lateral adjustment, by bolts 44 passed through slots in the carrier, to the front face of a forwardly projecting portion 45 of the machine frame 46. An adjusting screw 48 is mounted in each side of the carrier 42 in position to engage opposite sides of the frame portion 45. By turning these screws the carrier may be adjusted in the line of feed, transversely of the frame. By a suitable adjustment of the carrier 42, the channel knife which fits into a slot in the slide 66.

slide 38 and its channel knife 22 are bodily shifted in the line of feed, to vary the lead of the channel knife with relation to the edge knife for operating on soles having differently shaped toes.

The channel knife presser-gage 30 (Figs. 3 and 10) has a vertical tongue and slot mounting in a carrier 50 which is secured to the lower end of the channel knife slide 36 by the bolt 40. The presser-gage 30 may be adjusted on the carrier 50 to vary its vertical relation to the channel knife by means of an adjusting screw 52 which has its head rotatably mounted in the carrier 50 and is threaded into the upper end of the pressergage 30, said gage being locked in adjusted position on the carrier 50 by a headed screw 53. The channel knife'22' and presser-gage 30 are yieldingly held in working position relative to the sole on the table 20, by means of a compression spring 54, (Figs. 3 and 6) which is mounted between the upper end of the slide 38 and an adjusting screw 56 mounted in a yoke 58 formed on the upper end of the carrier 42. With this construction the pressure on the sole by the presser-gage 30 may be altered by varying the tension of the spring 54. The depth of the channel cut is determined, as usual, by the distance the cutting edge of the channel knife projects below the sole-engaging face of its presser-gage. A lug 60 projects forwardly from the upper end of the slide 38, and an adjusting screw 62, threaded therein, is arranged to engage an underlying flange on the carrier 42... The screw 62 limits the lowermost position which the prcsser-gage and channel knife may occupy with relation to the table, and prevents the channel knife from coming into contact with the face of the table when there is no workin the machine.

The edge knife 24, best shown in Figs. 4, 6, 8 and 9, is mounted in a carrier 64 which is attached to the lower end of an edge knife silde 66 at its rear side. The slide 66 is mounted in a vertical guideway in the machine frame 46 and is held in position by a cover plate 67 (Fig. 8). The edge knife is locked in position in the carrier 64 by a pair of set screws 68, which permit its adjustment in the carrier for wear. To vary the distance of the bottom of the edge out from the lower or grain face of the sole the edge knife carrier 64 may be adjusted vertically on the slide 66 by a thumb screw 70 which is threaded through a lug at the upper end of the carrier 64 and has a. flanged head The carrier 64 is locked in adjusted position by means of a screw 72 which passes through a vertical slot in the carrier and is threaded in the slide 66. The construction just described provides for the advantages described in my prior Patent No. 1,030,703,

dated June 25, 1912. A lug 74 is formed on the rear side of the upper end of the slide 66 and rests upon an abutment 76 formed on an adjusting bolt 78 which is threaded into a flange formed at the upper edge of the cover plate 67. The adjusting bolt 78 extends above the lug 74 and a strong compression spring 79 is held between the upper face of the lug and a nut 80 on the upper end of the bolt. Thus the edge knife, by means of the strong spring 79, is held firmly in working position with relation to the sole on the table 20, such position being determined by the engagement of the lug T4. with the abutment 76, but it is also yieldingly held so that it can be withdrawn from the table to insert new work.

The edge presser-gage 32 is located above the table directly in front of the edge and shoulder knives (Figs. 8 and 9). The gage 32 is adjus'tably mounted, as usual, on the lower end of a presser-gage slide 82 which is mounted independently of the edge knife, being held in position in a slot in the frame l6 by a cover plate 83 (see also Fig. l). A lug 84 is formed at the front of the-upper end of the slide 82 and rests on an abutment 86 formed on an adjusting bolt 88 which is threaded into a flange formed on the upper edge of the cover plate 83. The adjusting bolt 88 passes through and extends above the abutment 84 and a compression spring 89, weak as compared with the edge knife spring 79, is held between the upper face of the lug and a nut 90 threaded on the upper end of the bolt. With this construction the edge presser-gage is held yieldingly in working position upon the sole on the table and when there is no sole in the machine its lowermost position is determined by the en gagement of the lug 84 with the abutment 86. Figs. 7 and 8 show the parts all in operative position but the sole is omitted in order to avoid confusion. Patents Nos. 1,236,660 and 1,236,661, dated August- 1 1, 1917, and granted on applications filed by the present inventor describe a channeling machine in which three, instead of the usual two, knives are employed, namely, channel and shoulder knives which are gaged for depth from the upper surface, or flesh side, of the sole and an edge knife which is gaged from the opposite, or grain side, of the sole. The machine of the present invention embodies substantially like mechanism. The shoulder knife 26 (Figs. 8 and 9) is adjustably mounted in a slot in the side of the presser-gage 32 and is locked in position by a cap screw 92 and clamp plate 93. The cutting edge of the shoulder knife makes a V-shaped cut, the depth of which is measured from the upper side of the sole by the presser-gage 32 and is preferably of the same depth as the channel cut. lVith this construction the pressergage 32 will hold the sole down on the table for both the edge and shoulder cuts. The shoulder cut for a turn sole is measured from the upper side of the sole, since the gage 32 and shoulder knife are secured together, but the edge out is measured from the lower side of the'sole, or the surface of the table, since the gage 32 yields independently of the edge knife and the edge knife is fixed in vertical position during the operation of the machine by the strong spring 79. This construction insures that the edge of a turn sole willbe of uniform thickness and the shoulder will have a uniform depth, whetheror not the sole thickness varies from one end to the other, as explained more fully in said prior patents.

i Channeling machines for operating on welt insoles are distinguished from those for operating on turn soles by the fact that in a welt machine the vertical position of the edge knife is variable and is determined by the position of the edge presser gage with which it is rigidly connected, while in a turn machine the vertical position of the edge knife is fixed and the edge presser gage is freely movable with relation to the edge knife. I

In channeling welt insoles the depth of both the channel and edge cuts are gaged from the upper, or flesh, side of the sole. As the majority of welt insoles are fitted with a channel and an edge slit which form a flap and a parallel outer marginal lip, a

shoulder knife is not required. To adapt the machine for both welt and turn work the edge knife slide 66 and the edge pressergage slide 82 are connected together, and arranged so that they will move independ ently of one another for turn work or may move in unison for welt work. To this end a sleeve 94 (Fig. 8) is formed on the up per end of the edge knife slide 66 and a bushing 96 is slidably mounted therein. An adjusting screw 98 is threaded in the bushing and has a reduced portion at its lower end which is threaded into a rearwardly projecting lug 100 formed on the upper end of the edge presser-gage slide 82'. The sleeve 9% is split and is provided with a locking belt 102 by which'it may be clamped to the bushing 96. To adapt the machine for channeling welt insoles the shoulder knife 26 is removed from the edge gage 32, a plain edge knife is substituted for the edge knife 24 as the indented corner to receive the shoulder knife is no longer needed, and the bushing 96 isclamped in the sleeve 94. It is also preferable to remove the spring 89 or to replace it with a weaker spring so that the operation of the slides will be taken care of by the spring 79, which should be weakened by expansion to equal the strength of the channel knife slide spring 54. The thread on the portion of the adjusting screw 98.

which engages the bushing 96 has a different pitch from the thread which engages the lug 100, so that by adjusting the screws 98, when the bushing is locked in the sleeve 94, the vertical relation of the edge presser-gage to the edge knife may be varied, and hence the depth of the edge out from the flesh side of the sole altered.

The table 20 (Figs. 1, 6 and 8) is formed on the upper end of a tubular shank 104, slidably mounted in a bore in a bracket 106, which is attached to the frame 46 by a pair of bolts 108. The hand lever 109 for adjusting the table in the bracket 106, to position soles of different thickness with relation to the channeling devices and the treadle operated toggle links 110 and 112 (Figs. 1, 3 and 4) with the tension spring 114 connected between the machine frame and the toggle for lowering, raising and locking the l table in its sole supportingposition, all have substantially the same construction and mode of operation as that illustrated in the reissue patent to Adam H. Prenzel, No. 13,375, dated February 27, 1912, and, since these features form no part of the present invenl the line of feed to vary, as may be desired,

the position of the sole with relation to the hanneling devices. The edge gage 28 is adjustably mounted in a carrier 116 (Figs. 3, 7 9, and 10) which is pivotally mounted, for purpose to be later described, on the upper edge of an adjusting slide 118. The slide 118 has a dove-tail connection with a block 120 which is fixed to the table shank 104 by means of a bolt 122. To adjust the slide 118 transversely of the line of feed to vary the position of the edge gage, a slot 124 (Fig. 7) is formed in the lower face of the slide and receives a block 126, which is loosely carried by an eccentric stud 128 formed at the upper side of the head 131 of an adjusting shaft 130. The head of the shaft is rotatably mounted in a plate 132 secured to the lower edge of the block 120. The shaft 130 is rotated to shift the slide 113 by a hand lever 134 which is pivoted to a bracket 136 secured to the lower end of the shaft. To look the slide 118 in ad justed position a pair of pawls 138 (Figs. 3, 5 and 7) are pivoted to the bracket 136 and arranged to engage successively first alug 139 on the plate 132, then a notch 140 in a plate 141 adjustably secured to the lower side of the plate 132, then a notch 142 in a similar plate 143 and finally an adjustable stop screw 144 mounted in the plate 132.

From an inspection of Figs. 5 and 7 it will be apparent that the handle 134 may be locked in four different positions to produce the four variations in the width of feather commonly employed in channeling welt insoles. As the edge gage 28 is adjustably secured on the carrier 116 by the screw and slot connection 117 and the plates 141 and 143 are adjustably secured to each other and to the fiifed plate 132 by screws 133,

these four positions of the edge gage maybe varied as the work may require. The pawls 138 are yieldingly held in engagement with the notches 140 and 142 by means of springpressed plungers 148 which are mounted in the bracket 136 in position to engage tails on the pawls. To release the pawls from the notches in order to permit adjustment of the slide 118, abutment screws 150 are mounted in the lower side of the hand lever 134 in position to engage the tails of the pawls opposite the plungers 148, so that when the hand lever is depressed the pawls will be lifted out. of the notches and the shaft 130 may be r tated. lVith this construction the edge gage and its adjusting mechanism will be moved upwardlyand downwardly when the table shank 104 is operated bv the toggle 110112, and the edge gage will always maintain its working position relative to the surface of the table 20.

A four motion feeding device is provided to draw the sole against the cutting edges of the knives to produce the various cuts. The feeding device consists of a feed foot 160 (Figs. 6, 7, 8 and for engaging the flesh side of the sole, and a feed slide 154 mounted to slide in the table 20, for engagi ng the grain side of the sole. The feed foot has four motions, which comprise a clownward stroke to clamp the sole against the feed slide, a forward stroke away from the cutting knives to draw the sole against the knives, an upward stroke to release the sole, and a return stroke preparatory for the next feeding operation, while the feed slide has merely a reciprocating motion which occurs during the feed and return strokes of the feed foot. The feed foot is secured to the end of an arm 161 extending forwardly from the upper end of a vertical slide 162 and is arranged to reciprocate in the line of feed. The slide 162 has a dovetail mounting (see Fig. 5) in a carrier 164, which has a horizontal stud 166 at its lower end (Figs. 6 and 7) pivotally mounted in the lower part of the frame 46. To oscillate the carrier 164, to move the feed foot 160 toward and from the cutting edge of the knives, a link 168 is pivotally connected between the carrier and a block 170, which is slidably mounted in slotted crank 172. The crank 172 is pivoted at its lower end to a rearwardly projccting bracket 17 4 on the frame 46, and an eccentric rod 176 is connected between the upper end of the crank and an eccentric 17 8 formed near the left-hand end of a driving shaft 180.

The feed slide 154; extends entirely across the table 20 (see Figs. 5 and 8) and its width is sufficient to manage a comparatively large portion of the ain face of the sole. To reciprocate the feed slide simultaneously with the forward and return strokes of the feed foot 160. the feed slide is connected with the carrier 16 by a link 182 (Fig. 8) which has one end loosely mounted on a stud 184 projecting downwardly from the feed slide and the other end rotatably mounted in a boss 1% fori'ned'on the front side of the carrier.

The vertical movement of the feed foot 160, into and out of gri ping engagement with the sole, is obtained y a vertical reciprocation of the slide 162. In order that the feed foot may accommodate itself to variations in the thickness of the work and to avoid excessive pressure thereon, the feed foot is brought yieldingly into engagement with the sole. The movement of the foot away from the sole, however, is positive. The vertical movement of the slide 162 is produced by an eccentric 188 on the end of the shaft 180 connected by an eccentric strap 190 with the block 192. A rod 19 1is pinned to the block 192 and mounted to slide in bearings 200 formed on the slide 162. 'A spring 202 interposed between the block and the lower bearing 200 transmits a yielding downward movement to the slide under the action of the eccentric 188, so that the slide moves downwardly until the feed foot engages the sole after which the spring 202 absorbs the excess movement. It is desirable that the vertical position of the feed foot 160 shall be capable of adjustment for variation in the thickness of the soles to be operated upon in order that the foot may always engage the sole at about one half of its downward movement. To provide this adjustment the lower end of the rod 194 is threaded and provided with lock nuts 195 which bear upon the under side of the lower bearing 200 when the presser foot is raised from the work. By adjusting these nuts the vertical relation of the block 192 and the slide 161 may be varied as required. When the nuts are screwed up to raise the feed foot the spring 202 will be compressed to a greater extent, thereby increasing its strength, which is desirable, as a greater spring pressure of the feed foot is required for thick soles than for thin ones. On the upward movement of the eccentric the spring 202 will expand until the nuts 195 engage the lower bearing 200 after which feed foot will be positively lifted from the sole.

By having the large surface of the feed slide 154 in engagement with the sole while the slide is positively moved in feeding the sole, the face of the feeding foot 160 which engages the sole may be comparatively smooth and still effect positive feeding of the sole. This is especiallyadvantageous because such a feed foot does not mutilate the between substance on which it acts. As the channel presser gage 30 and edge presser gage 32 are not used for the purpose of feeding the sole, they may have a long bearing upon the sole across the line of feed (see Fig. 9) and be under a comparatively light spring pressure which facilitates turning the sole when channeling around the curved portions, particularly at the toe. Since the feed slide remains in contact with the sole on its return stroke it tends to slightly withdraw the sole from the knives. This is advantageous, as the sole will have an initial movement on the next feed stroke before it is brought into engagement with the cutting edges of the knives which reduces the cut ting strain on the knives and permits a higher speed of operation.

Although a high rate of feed is desirable and preferable along the shank and the'forepart of the sole where the edge is comparatively straight, it is difficult to guide the sole as it is being cut around the toe. It is desirable. therefore, that the speed of the feed of the work may be varied in order to secure the best character of channeling. To vary the speed of the feeding devices the block 170 (Fig. 7) is slidably mounted in the slotted crank 172, and is arranged to be moved toward and away from the pivot of the crank to decrease or increase the length of feed step and consequently the speed of the feed. To this end the block 170 is connected by a depending link 206 with the outer end of a lifting lever 208, which is pivoted on a pin 210 (Fig. 7) mounted near the base of the frame 46. A torsion spring 212 is connected between the lever 208 and pin 210 and acts to hold the slide block in its uppermost position, which position is determined by the engagement of a set screw 21 i (Figs. 1 and 7) mounted in a rearwardly projecting arm 216 on the lever, with a lug 218 formed on the frame 46.

The lowermost position of the slide block 170 is determined by means of a set screw 1 which is threaded in'the lower end of the crank 172. By properly adjusting these two set screws any desired range of speed may be obtained. The block 170 is shifted in the crank by means of a treadle rod 222,

to the channeling devices. To insure a higher speed of operation, both the starting and the stopping of the feeding devices are arranged to be automatically controlled by the vertical movement of the work table clutch, which consists of a belt driven pnl" ley 224, loosely mounted on the shaft, and a clutching member 226 mounted to rotate with the shaft (Figs. 1, 2, 4 and 5). The clutching member 226 has a eonicalfriction face 228 at one end of the central hub, adapted to fit in a conical recess 230 in the pulley 224, and a frictionibraking face 282 at the other end of the hub, adapted to engage a corresponding braking face 234 formed on the frame46. The clutching member is'slidably mounted on a sleeve 286 fixed on the driving shaft, and is held for rotation with the sleeve by a spline 288 (dotted lines Fig. 5). A compression spring 240, surrounding the sleeve 236 within the clutching member, is Y confined between a flange 242 on the clutching member and a flange 244 on the sleeve, and normally acts to hold the clutching member in a driving engagement with the pulley 224.

To shift the clutching member into and.

out of driving engagement with the pulley '224, a cam face 248 (Figs; 1, 4 and 5) is formed on the clutching member at the end of its central hub. A roll 250, carried on the upper end of shifting lever 252, (Fig. 1) pivoted on a boss 254 projecting from the frame 46, is in operative relation with the cam face 248. The lower end of the lever 252 is connected with one link 256 of a locking toggle 256258, and the other link 258 of the toggle is pivotally connected to the front of the frame 46. Looking lugs 260 and 262 are formed on the ends of the toggle links 256 and 258 respectively in a position to lock the toggle when its knuckle is moved slightly-beyond the position necessary to straighten the toggle. A coil spring 264', connected between the toggle links, tends to hold the locking lugs ingeng'agement with one another when in the position just described. An adjustable link 266 is connected between the toggle link 258 and the rear end of a connecting lever 268, which is pivoted on the front of the frame 46. The forward end of the connecting lever is provided with a throat (Figs. 1, 5 and 13) formedby the upper face of a lug 270, at the bottom edge of the lever, and the lower end of a screw 272 threaded into a lug on the upper edge of the lever overhanging the lug 270. The throat is'adapted to receive an arm 274 projecting rearwardly "from the pivoted edge gage carrier'116. This form of connectlon between the edge gage carrier and the' connecting lever 268 permits the edge gage to be freely adjusted transversely of the line of feed as may be desired. To support the arm 274 during its vertical movement when actuating the connecting lever, a lug 276 formed on the upper edge of the edge gage slide 118 projects over the arm at the time it is in the throat of the con necting lever.

With the construction just described it will be seen that the clutching member 226'? clutching member into engagement with d the pulley 224. hen the table is moved downwardly the toggle is straightened and locked, and the cam roll 250 is moveda distance to the left, (Fig. 1) into position to engage the rise of the cam 248 which so poit sitioned with reference to the cycle of the machine that it will engage the roll 250 and the clutch member 226 will be moved to the left, to apply the brake and stop the machine, at the time when the feed foot 160 is lifted from the sole, As the feed foot is at its greatest elevation at 180 from the positions shown in Figs. 7 and 8, the machine will stop with the feed footabout midway of its idle or return stroke. The locking of the toggle in straightened position holds the clutching member disconnected from the driving pulley until the toggle is again broken by an actuation of the connecting lever through an upward movement of the work table.

Asheretofore described, the work table is normally held in its upper or working position by the spring114 (Fig. 1) the arrangement being such that when the foot treadle is released the table. will be antomatically raised by the spring. To prevent the work feeding devices from being set into operation when thefivork table is raised in this manner and there is no sole thereon, the actuation of the driving mechgage. The edge gage carrier 116 may be rotated on its pivot with relation to the table to bring the edge gage into a sole guiding position or a sole detecting position. When the edge page is in its sole guiding position the arnr2'i4 on the edge gage carrier is held in the throat of the connecting lever 268. at which time a movement of the table will act to either start or stop the driving mechanism. hen, however, a sole is removed from the table the edge gage is permitted, as will presently be explained, to advance across the table under the influence of a spring; pressed plunger 280 7) which is carried by the lug 276 and bears on the outer side of the arm 2. 4. With the arm 274 discon- Elli) nected from the connecting lever 268 the table may be freely moved up and down without affecting the driving mechanism of the feeding devices.

To start the machine for channeling a sole the operator places the sole on the table while it is held in lowered position, and pushes the edge of the sole against the edge gage to rotate the edge gage from the detecting position into the sole guiding position. Then as the table is moved upward ly to present the sole to the channeling devices, the edge gage will be locked in a sole guiding position by means of a springpressed plunger 282 (Figs. 1 and 10) which is mounted in a boss formed on the lower side of the cover plate 83 and arranged to engage a groove 284 (Fig. 5) formed for its reception in the arm 274. While the table is being moved down to permit removal of a sole the plunger 282 will follow down with the arm 274 and retain the edge gage in guiding position until the toggle 256 258 has been straightened. Thereafter, a further downward movement of the table will draw the arm 274 below the plunger 282 and permit the plunger 280 to force the arm 274 out of the throat of the connecting lever and move the edge gage into detecting position.

To facilitate the removal of the sole from the channeling devices, it is desirable ,to lift the channeling devices away from the sole as well as to lower the work table. To accomplish this a horizontal link 284 (Figs. 1, 4, and 6) is connected between an arm 285 at the upper end of the table toggle link 110 and the vertical arm of a bell crank 286, pivoted to the rear side of the frame 46. An adjustable link 288 is connected between the horizontal arm of the bell crank 286 and an arm 290. (Fig. 2) on a yoke which is loosely pivoted on a shaft 294 above the frame 46 journaled be tween a pair of arms 296 extending outwardly and upwardly from the frame. The yoke carries a series of three adjustable screws 298, which are located above the rear ends of a series of levers 300, 302 and 304, loosely pivoted on the shaft 294, between the arms of the yoke. The forward end of the lever 300 engages the lug 74 (Fig. 8) on the edge knife slide 66. The forward end of the lever 302 engages a lug 306 (Fig. (3) formed on the rear side of the channel knife slide 38. The forward end of the lever 304 engages the lug 84 on the presser- In channeling different types of soles it is requisite to remove and reinsert, one or another of the knives at certain points along the sole edge during the continuous feed of the sole, as is well known to those skilled in the art. To accomplish this a second yoke 308 (Figs. 2 and 6) is pinned to the shaft 294 within the yoke 292. A series of three adjustable screws 310 are mounted in the yoke 308 above the rear ends of the levers 300, 302 and 304. To operate the yoke 308 an arm 312 (Figs. 1 and 2) is pinned to the front end of the shaft 294 and arranged to be connected with a foot treadle by a rod3l4. The adjustable screws 310 may be withdrawn toprcvent engagement with the lovers 300, 302 and 304, so that any one, or all, of the slides 38, 6G and 82 may be raised by depressing the treadlc connected to the rod 314.

The operation of the machine will be apparent from the foregoing description, and it will only be necessary to conclude with a reference to some of the more important advantages of the construction hereinbefore described. The feature of interchangeability from welt work to turn work is a new and important development in machines for channeling soles; andin this connection ability of the operator on welt work to test the thickness of the lip being cut, on the first sole fed from any stint of work, while the machine is working, is exceedingly valuable. This is accomplished by adjusting the screw 98 (Fig. 8) after the sleeve 94 has been tightened on the bushing 96, which screw, (see Fig. 2) is within easy reach of the operator. Such an adjustment varies the vertical relation of the edge presser gage 32 to the edge knife 24, and consequently the depth of cut of said knife. This feature is particularly advantageous in gem insole work. cation of the feed foot 160 on the between substance and back of the cutting edges of the knives (see Fig. 9). This location prevents any disturbance of the flesh on the sole where the cuts are to be made, and leaves a free space at the front of the knives for broad channel and edge gages which will iron down the flesh on the sole across the full width of the portion to be cut. The location of the feed foot is such that the greatest pressureis applied back of the cutting edges of the knives, gives a greater freedom to turn the sole during the feed and produces more even work. The automatic starting mechanism forces the operator to begin the cuts at the breast of the heel because he must place the sole under the pres ser gages before the feed foot will engage the sole to feed it. This eliminates cutting in from the edge of the heel seat and avoids weakening this portion of the sole. By utilizing the edge gage to start the machine,

Another important feature is the 10- the starting may be accomplished by a sole of any thickness without adding more friction or spring pressure on the sole, as is necessary if a clutch tripping feeler is utilized to engage the face of the sole.

In the foregoing description and in the following claims, the term channeling devices is used. which is understood to refer to the channel knife, edge knife, and shoulder knife. and their co-operating pressergages.
