31 Claims.

This invention relates to improvements in solefitting machines and is illustrated herein as embodied in a channeling machine which is adapted sharply pointed-toe style is considerably more diflicult than is the same operation on a broadtoe style because the turning radius is smaller in the pointed-toe sole with the result that there is less room in which to make the turn.

It is an object of this invention to provide improvements in sole-fitting machines which will make it easier for operators to turn or swing soles about sharp corners. To this end, the illustrated machinawhich is equipped with a pair of knives arranged to operate on the marginal portion of a sole, is provided with means which can be adjusted during the operation of the machine to shorten the stroke of the knives when the operation approaches a sharp corner, and, in addition, the machine is provided with further means which is arranged to slow down the speed of the knives when their stroke is shortened. This construction makes it easier to turn the sole and also retards the speed of the feed which is desirable when operating around corners. The controls for the above-mentioned means are both connected to a treadle so that when the operation approaches a corner, the operator can shorten the stroke of the knives, reduce the rapidity of their movement, and retard the speed of the feed by operating the treadle with his foot, and at the same time he can use both hands to swing the sole about the point of operation.

Further to facilitate turning of the sole, and in accordance with another feature of this invention, means are provided for disengaging the feed device from the sole member during a substantial part of each operating cycle. As illustrated, this means comprises a cam which moves the feed device heightwise from the sole member at the end of each cutting stroke and holds it away from the work fora substantial period during each operating cycle so-as to give the operator ample opportunity to adjust the position of the sole between the successive cutting "strokes.

'Hereto fore, when it was desired to channel an insole having an extension-such, for example, as the wing "or tab portion of an orthopedic insole -andto chamfer or bevel the-edge of the sole at the rower 'or'grain side, it was necessary to perform two separate machine operations, i. e.,

channeling and beveling. This was due to the fact that beveling knives in machines heretofore available could not be moved out of the path of the relatively wide sole extension on this't'ype of in'sole during the operation of the machine "and hence would gouge the under or grain surface-of the "extension if a channeling operation were carried out in the portion of the sole contiguous to the extension.

With this in view, it is another object of the invention-to provide an improvedsole-fitting'machine which is capable of simultaneously channeling and beveling themargin'al portion of an orthopedic insole and thus accomplishingin one machine operation results whichyhave heretofore required two separate operations. To this 'the provision of mounting means for the chamfering knife which is so arranged that the chamfering knife can readily be moved below the surface of the "work table during the operation of the machine and thus permit the sole extension to pass over the chamfering knife without being cut thereby and the channeling operation to progress through the portion of the sole contiguous to the extension. In accordance with another aspect of this feature of the invention, means are provided for interconnecting'the-edge gage and the chamfe'ring knife so that the edge gage can be moved out of the path of the 'sole extension at the same time the chamfering'knife is moved below the surface of the work table. As illustrated, the interconnected edge'gage and chamfering knife are mounted 'on the worktable carrier which is arranged to adjust them transversely to the line of feed through a normal range of adjustment and, when an extension of the sole is encountered, 'to 'move'them to a predetermined position 'Where an abutment acting on the interconnecting means causes the edge gage and the charnfering knife "to move heightwise of the surface of the work table to a position where they are out of the path of the sole extension. It has been found that in sole-fitting machines wh'ifethe knives "and the feed devices move in ream paths, the feed of the "work With this in mind, it is another object of the.

invention to provide further improvements in sole-fitting machines, which will overcome rotatable work table l2 which is mounted on an adjustable carrier l3. Adjacent to one side of the work table is a chamfering knife 14 (Fig. 3) which is also supported on the carrier, while above the work table is an inner tool carrier I6, and an outer tool carrier !8. The elements just mentioned correspond respectively to those indicated by the numerals 14,40, 420, 62 and 64 in the above-mentioned patent to Bertrand.

The inner tool carrier'lfi (Fig. 2) is mounted for straight line movement by means of a pair of plates 20, 22 which are fastened to the tool cartwitching of the sole as it is fed past the chamfering' knife and thereby improve the appearance of the beveling cut made by that knife. This object is attained by mounting one of the tool-supporting members for straight-line movement, and the other tool-supporting member for In accordance with a preradial movement. I ferredarrangement, the outer or edge knife'and the inner or channeling knife are mounted on the straight-line tool-supporting member, and a feed device is mounted on the radially movable member, Movementof the channel knifein a straight line practically eliminates the throw of the work against theedge gage, while the solegripping action of both of the knives largely prevents the feeding forces from moving the sole away from the edge gage. g V

Invention is also to be recognized in the driving mechanism for oppositely moving the radial and the straight-linetool-supporting members, and in the simple. and efficient control system for raising and lowering the work-feed device in timedrelation to the movement of the tool carriers. u

With the above and other objects in view, the invention will now be described with reference to the accompanying drawings, and will be pointed out in the appended claims.

The'machine shown in the drawings is of the type illustrated in Letters Patent of the United Si ates'No. 2,015,064, granted September 24,1935 upon application of F. E. Bertrand,"and comprises a .headlfl in which ismounted a freely rier by screws 24 and engage respectively the opposite undercut sides of a dovetailed guideway 26 formed on the inside of the end wall 21 of the head I0. A tool slide 28 is mounted for vertical movementin a slideway 36 within the tool carrier it. The slide 28 is adapted to yield upwardly against the action of a coil spring 32 which is housed within a bore in the upper part of the slide, the upper end of the spring bearing against afollower .34 which is engaged byan adjustable screw 35 threaded in a collar 38 clamped-to a pin 40 which, in turn, is fastened to the upper plate .26. Downward movement of theknife slide 28 under the influence of the spring 32 is limited by a crossbar l2 which corresponds to the crossbar 23$ inthe machine disclosed inthe above-mentioned Bertrand patent. a

The outer tool carrier !8 (Fig. 2) is located opposite to the straight line carrier l6 and is provided with laterally extending heightwise spaced arms 44, 45 which extend over the top and bottom surfaces of a shoulder Q8 formed on the head it. The carrier I8 is pivoted to the shoulder 18 by a hollow sleeve 50 which extends through alined openings in the arm 44, the shoulder 48 and the arm 46, the sleeve being attached to the arms by means of pins 52. The axis of the pivot sleeve is vertical and normal to the plane of a sole on the. sole support I2, and oscillatory movement about this axis will not therefore include up-and-down components relatively to the sole. A second slide 54 consisting of a spindle 56 and a sleeve 58 is mounted for vertical movement in. a slideway 60 within the carrier. l8. A feed foot 82' is carried by the lower end of the spindle 56.

The sleeve 58 is formed witha counterbored recess for receiving a coil spring 62 which en.-

'circles the spindle'56, the lower'endof the spring to the sleeve 58 and maintain the spindle in a vertical position determined by;the engagement of a crosspin S6 in the spindle with the lower end of a vertical groove 68, in the sleeve .58. The spring will be compressed by continued downward movement of the'sleeve after the tool carried by the spindle 56 has engaged the'work on the table 12, thus adapting the tool carrier. spindleto a-ccommodate soles ofdifferent thicknesses.

The sleeve 58is provided. with an ear lilwhich is connected to a swinging lever 12 by a link 14, the lever being mounted on a transverse crossshaft 16 which is carried by spaced uprights 18, 30 (Fig. 1)". As the tool carrier l8 moves the sleeve 58 laterally with res-pect tov the path of movement of the lever 72, V ballandsocket joints are used to form the connections between the ear 1a, thelink I l and the lever 12, these joints preferably being of the'type shown in the United l I v States Letters Patent No. 2,173,155, granted September 19, 1939 upon an application filed in the name of F. E. Bertrand.

In the illustrated form of my invention, the channeling knife I50 (Fig. 4), the edge knife I52, and the presser gage I54 are all fastened to the knife slide 28 on the tool carrier I6. The means for fastening the channeling knife to the slide consists of a screw I56 which passes through an opening I58 in va knife block I60 and then into threaded engagement with the channeling knife. The block I60 is securedto a knife-block holder I62 by a screw I64 which passes through a hori- -zontal elongated opening I66 in the block holder and then into threaded engagement with a tapped hole I68 in the knife-block I69; the elongated opening I66 permitting lateral adjustment of the channeling knife. The knife-block holder I62 is clamped to the slide 28 by a quickly releasable connection consisting .of .a slotted cap plate I70 which fits around the head of a screw I72 that passes through a second elongated opening I74 in the block holder I62 and then into threaded engagement with an opening I76 in the tool carrier. vertical direction, making it possible to adjust the channel knife in a heightwise direction. When the knife-block holder I62 has been moved to a desired heightwise position and clamped against the tool slide, the screw I72 is held against rotation by a clamp screw H8. To release the knife-block holder I62, the cap plate I70 is rotated in a counterclockwise direction a short distance to loosen the screw I72 and the cap plate is slid out from under the head of the screw, thus loosening the screw so that it can be backed off by hand if desired.

The edge knife I52 is mounted on a knife block I80 which is fastened to one end of a bracket I82 by a screw I84 which extends through an elongated vertical opening I85 in the block I80. The bracket I82 extends laterally from the slide 28, and is connected thereto by a screw I86. The screw I84 is provided with a slotted cap plat I88 which functions in the same manner as the cap plate I78 and, in addition, the screw is locked in its tightened position by a clamping screw I87. The presser gage I54 is fastened to a notched portion of the lower end of the tool slide 28 by a screw I92 (Figs. 3 and 4). The presser gage extends parallel to the bracket I82 and is provided with a pair of spaced downwardly extending presser feet I94, I96 which are located a slight distance in advance of the channeling knife I50 and the edge knife I52.

The tool carriers I6, I8 are oppositely moved back and forth by a lever 86 (Figs. 1 and having 21. depending spindle 88 which is pivoted in a bearing 89 on the top of the head I0. The lever 86 is connected to a crank arm 90 on the outer tool carrier I8 by a link 92, and to the hinge joint 96 of a toggle which operates the slide I6 by a second link 94. The toggle consists of an arm 98 pivoted on a post 99 extending upwardly from the head I0, and a link I00 connected at one end to the pin 40 on the upper plate 20, the arm 98, link :00 and link 94 being connected together at the hinge joint 96. Thus, when the lever 86 is moved in a counterclockwise direction, as viewed in Fig. 1, the crank arm 90 is rotated in a counterclockwise direction, causing the tool carrier I8 to move rearwardly, and at the same time the arm 98 is also moved in a counterclockwise direction moving the hinge joint 86 for- Tne elongated opening I74 extends in a 1 'wardly and causing the tool carriage I6 to move forwardly. I

The link 82 is connected to the lever 86 by a slide I02 (Fig. 1) which is mounted in a'groove I04 formed in the top of the lever, and the extent of movement of the tool carriers is varied by adjusting the slide in the groove relatively to the axis of oscillation ofthe lever. The adjustment of the slide I02 is effected by the operation of a lever I06 which is connected-to the link 92 by an adjustable link I08, the lever being operated by a rockshaft IIO which extends rearwardly beyond the head I0 to a point where it is connected with a treadle (not shown) by means of a. rod II 2 (Fig. 3). The rockshaft .0, rod H2, and the treadle (not shown) correspond respectively tothe members 648, 656 and 658 in the patent to Bertrand No. 2,015,064.

The lever 86 is oscillated back and forth by a three-motion cam II4 (Fig. 5) which is surrounded by a cam-follower housingIIB that is moved back and forth by the cam, the housing II6 being connected to the lever 86 by a pin II8 (Figs. 1 and 5) which is fastened to an upstanding arm I20 on the rear end of the lever 86. The cam H4 is mounted on the upper end of a vertical drive shaft I22 which corresponds to the drive shaft '70 in the before-mentioned Bertrand Patent No. 2,015,064.

The cam H4 (Fig. 5) consists of a segment I24 of uniform radius, a segment I26 of decreasing radius, a third segment I28 of uniform radius, this radius being less than that of the segment I24, and a fourth segment I30 of increasing radius. When the cam is rotated in a clockwise direction from the position shown in Fig. 5, the segment I26 causes the lever 86 to move in a counterclockwise direction and the knives I50, I52 on the one hand and the feed foot 82 on the. other hand to move toward each other on a cutting stroke. At the end of this movement, the segment I24 causes a dwell or suspension in the movements of the tool carriers, after which the segment I30 causes the tool carriers to reverse their motion and move the knives and the feed foot back to their starting positions; and, when they. reach those positions, the segment I28 will cause a second dwell. A the cam I I4 rotates, it acts on wear plates I32, I34, which are mounted in 'the cam follower H6, and is lubricated by wicks I36 that are mounted in oil pockets formed in the cam follower.

The arrangement described above substantially eliminates the before-mentioned twitching which heretofore accompanied the work feed and makes it possible for the chamfering knife to form a smooth, beveled surface. This is due to the fact that movement of the channeling knife in a straight line practically eliminates the throw of. the work against the edge gage, while the gripping action of the knives I50, I52 and the presser feet I94, I96 on the work largely prevents the action of the feed foot 82 from moving the .sole edge away from the edge gage.

The heightwise movement of the feed foot 82 is controlled by a pin I88 which extends upwardly from the cam H4 .and is located eccentrically to the underlying drive shaft I22 (Fig. 5), the eccentric pin being connected by a .link I40 (Fig. 1) vto the swinging lever 72 which raises and lowers the feed foot. The eccentric pin is so located with respect to the control surfaces of the cam II4 that the pin lifts the feed foot fromthework during the dwell which follows thefee'd stroke and holds the feed foot .away

from the work throughout the return movement of the tool carriers and Well into the dwell which follows this return movement. Thus it' will be seen that during each operating cycle of the machine which is caused by the rotation of the drive shaft I22, the feed foot is disengaged from the work for approximately three-fourths of the operating cycle, giving the operator ample time to adjust the position of the work between each cutting stroke.

'When the operation. approaches a sharp corner, the operator customarily shifts the block I02 closer to the fulcrum of the lever 84, thereby reducing the amplitude of the oscillations imparted to. the tool carriers I6 and I8, shortening the stroke of the knives, and reducing somewhat the speed of the feed. The speed of the feed in the illustrated machine is further reduced at this time by reducing the frequency of the oscillations of the tool carriers, this result being obtained bymaking the vertical drive shaft I22 in two sections (Fig. 3) and connecting those sections by a friction-type slip clutch I42. The lower element of the clutch I42 is provided with a sleeve I43 which is slidably mounted on the lower section of the drive shaft I22 and has a peripheral groove in which are seated shifting pins I44.

The controls for the block I02 and the clutch I42 are interconnected by means which will now be described, so that the speed of the upper section of the shaft I22, to which the cam H4 is connected, will progressively be reduced as the block is moved closer to the fulcrum of the lever 86. To this end the shifting pins I44 are connected to a forked lever I45 (Figs. 1 and 3) which is in turn connected at I41 to the treadle operated rod II2 which controls the shaft H and through it the block I02. Thus, by depressing the treadle (not shown), the elements of the slip clutch I42 will be moved apart as the stroke of the tool carrier is shortened, thereby causing a slow-down in the frequency of their back and forth movements.

The chamfering knife I4 is mounted on a knife carrier 200 (Figs. 3 and 6) which is pivoted on a lug 202 that projects upwardly from a flat lever 2 34, the lug being located beneath the edge of the work table I2. The lever 204 rests 'on the top of the work table carrier l3 and is swingably connected .at its left end (Fig. 3) to a stud 206 which projects upwardly from the carrier I3. The opposite end of the lever 204 is attached to the lower portion of a post 208 that extends through a slot 2 (Fig. '7) in the forward end of an edge gauge supporting member 2I0 and has its upper portion connected, to an auxiliary work-supporting table 209 so that the auxiliary table moves with the lever. The

lever 204 is connected to the member 2I0 by a pin 20'! which extends through alined openings inthe lever and the member. The edge gage supporting member 2I0 is rectangular in shape and has an arm 2I2 which extends upwardly fromits rear, or the right portion of the memberas viewed in Fig. 6, the upper end of the arm being provided with a lateral extending pivot pin 2I'4 upon which an edge gage 2l6 is mounted.

The edge gage 2I6 and the chamfering knife I4 are oscillated back and forth by a rocker member -2I8 which is provided with a pair of spaced arms 220 (Fig. '7) which slidably engage the opposite sides of the edge gage supporting member 2I0, thereby causing the member 2I0 to oscillate with the rocker member 2! while permitting relative sliding horizontal movement be tween the members as required to permit inward and outward adjustment of the work table carrier I3 and the edge gagev 2I6. The rocker member 2I8 is pivoted on the head I0 by a post 222 (Fig. 2) which is fastened at, its lower end to the rocker member and extends upwardly into the opening in the sleeve 50 which also forms the pivot for the tool carrier I8. Movement of the tool carrier is transmitted to the rocker member 2I8 by means of a flat plate 224 which projects downwardly from the lower arm 46 on the tool carrier I8 into a slot 226 in the upper part of the rocker member. With the arrangement just described, the oscillating movements.

of the tool carrier I8 will be transmitted by the plate 224 to the rocker member 2I8 and to the member 2I0 which moves in unison with the rocker member. The member 2I0, in turn, transmits the oscillating movement through the pin 201 to the flat lever204 which is caused to swing back and forth about the stud 206. As chips are cut from a sole edge by the chamfering knife I4 they are carried away from the work table by a chute 221 (Figs. 1 and 6) which is attached to the chamfer knife carrier 200. From the chute 221 the chips pass through a second chute 228 fastened to the work table carrier I3 by bolts 229 (Fig. 1).

The chamfering knife and the edge gage are adjusted back and forth relatively to the channeling and edge knives I50, I52 by the backand-forth movement of the work-table carrier I3 which is controlled in the usual manner by V a hand lever 225 (Fig. 7) which corresponds to the hand lever 508'in the Bertrand Patent No. 2,015,064.

The'chamfering knife I4 and the edge gage 2I6 are arranged for heightvvise movement relative to the surface of the work table I2 so that they can be moved out of the path of an extension on an orthopedic insole. To this end, the edge gage 2I6 is provided with a downwardly extending arm 230 which is connected to an arm 232 extending downwardly from the chamfer knife carrier 200 by a link 234. The chamfering knife and the edge gage are maintained in their normal operative position by means of a coil spring 236 which is connected at one end to the lower end of the chamfering-knife arm 232 and at its other end to a pin 238 which projects out from the mid-portion of the edge-gage arm 230.

The edge gage and the chamfering knife will remain in their normal operative position shown in Fig. 6 while the work-table carrier I3 is adjusted back and forth to produce the usual variations in the Width of the feather about the periphery of an insole. When, however, an insole extension is encountered, the work table carrier is moved to the right, as viewed in Figs.

3 and 6, anadditional distance, causing an abutment 240 on the edge-gage arm 230 to strike the end of an abutmet screw 242 mounted on the rocker member 2B8. This causes the edge gage arm 230 to rotate in a clockwise direction, lifting the edge gage 2| 8 above the surface of the work, and at the same time, the displacement of the arm 230 moves the link 234 to the left, as viewed in Figs. 3 and 6, thereby causing the chamfer knife arm 232 also to rotate in a clockwise direction and move the chamfering knife I4 below the surface of the work support, as shown in Fig. 3.

Clockwise rotation of the chamfering-knife arm 232 "and the edge-gage arm 230 causes'an appreciable stretch in the spring 236 so that.

when the work-table carrier I3 isagain. moved to the. left. sufficiently to carry the abutment 24B. away from the screw 242, the. action of the spring on the'end of the chamfer-knife arm willcause that arm to move in a counterclockwise direction until it returns the chamfering knife to the position shown in Fig. 6. This movement ofthe arm 232-wi1l cause a corresponding displacement of the link 234 which will move-the edgegage down to its. operative position. The return movement of the chamfering knife and the edge gage will be stopped when the edge gage strikes the auxiliary work. table 209. It will be noticed that'the line of action. of the spring 236-passes closer to the pivot 214 of the edge-gage arm 230 than. it does to the pivot 263 of the chamfering-knife arm 232 so that. the action: of the spring will cause the movement of therchamfering knife and the edge. gage to their operative positions in theimanner just described.

The, work table I2 is raised and lowered by a mechanism similar to that disclosed in the Bertrant Patent No- 2,015,064, and in order to make sure that the rocker member 216 follows the downward movement of the work-table carrier,,thepost 222 (Fig. 2) which is fastened to therocker member 213, is urged downwardly by a: coil" spring 244: which is housed within the sleeve. 56. The lower. end of the spring abuts the; top of the member 222- while the upper end of" the spring bears against a follower 246- which is engaged by an adjustable screw 248 threaded in an overhanging; member 259; fastened to the toolcarrier I8;

The operation of the machinewillnow be described. After the channeling knife and the edge knife. are mounted on the knife carrier (Fig. 4), the machine is started and a sole is introduced into the machine in the usual; manner. As: the operation approaches a sharp corner, the operator depresses the treadle. (not shown) moving the link H2 (Fig. 3) downwardly. This movement of the link causes the shaft M to rotate in a clockwise direction, as viewed in,

Fig. 1, moving the lever N16 with it. The movement of the lever- H36 causes a corresponding movement of: the links. I68 and 92, which causes the block I62 to move in the slot lM'toward the fulcrum point of the lever 86 thereby reducing the amplitude of the oscillationsimparted' to the tool carriers 16- and I8. At the same-time, the downward movement of the link H2 causes the clutch; arm 165' (Fig; 3,) to move downwardly and separate the clutch elements, allowing them toslip relatively to each other and causing the machine to. slow down. After the operation progresses around the corner, the operator releases the'treadle and themachine resumes its normal operation.

As the operation'progresses around the periphcry of the sole. the operator moves the handle 2255 back and forth to vary the width ofthe feather. in a desired manner. If the sole being operated; upon isofthe orthopedic type provided with anextension, the operator moves the handle 22-5- to a predetermined position when the point of operation reaches the extension. This moves the work-table carrier 13 an additional distance to the right, as viewed in Fig. 3, causing the abutment screw 242. to strike the abutment' 2% and: move the edge-gage arm 230 in a clockwise direction. Movement of' the arm in this direction: lifts. theedge gage- 216 above: the insoleextension and also displaces the link 234- to theleft, causing. the chamfering-knife carrier to move in a clockwise direction so asto; lower the chamfering knife l4 below the surface of the Work table. When the point of operation passes beyond the extension, the handle 225 is moved back to one of its feather determining positions thereby causing the work-table carrier I3. to move to the left and the edge-gage arm 230. to move away from the abutment screw 242. When the arm 23!). moves away from this screw, the spring 236 moves the'edge gage 216 and the chamfering knife l4' back to their normal operating positions, shown in Fig. 6.
