SOLE-CHANNELING MACHINE.

Application filed January 22, 1906.

To all whom it may concern:

Be it known that I, EDWIN A. VVEBSTER, of Groveland, county of Essex, State of Massachusetts, have invented an Improvement in Sole-Channeling Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to certain improvements in that class of machines which are adapted to form a shoulder about or otherwise shape the edge of a sole to be used in a welted or turned shoe and to cut a slit or channel in the sole adjacent said edge. Machines in general use at the present time for this purpose usually comprise two or more fixed knives positioned to make the desired cuts in the sole as the sole is fed past them. In such machines it is customary to employ a pair of feed wheels for drawing the sole against the knives, and, as the bottom of the sole must not be marred in this process, it is customary to employ a smooth faced bottom feed wheel, so that the force neces sary to feed the sole must practically all be applied by the upper feed wheel, which is usually provided with projecting teeth which engage the sole in the between-substance, or that portion of the sole between the bottom of the channel and its edge. Generally this between-substance is very narrow, often less than of an inch thick and the result is that the projecting teeth on the upper feed wheel, which are usually nearly as wide as the between-substance is narrow, act to cut the between-substance almost entirely across wherever they enter it, so that the betweensubstance is thus very materially weakened at many points, and if the needle happens to pass through the between-substance at one of these points the stitch is liable to be pulled out. This weakening of the betweensubstance is particularly likely to occur about the toe and heel of the sole, as the teeth also tend to tear the between-substance transversely thereof, by reason of the turning of the sole while it is engaged by the teeth, and because of the pulling action more or less transversely of the between-substance.

My invention has for its primary object to produce a sole channeling machine which is adapted to perform its functions without the employment of feeding devices which will in any way injure the between-substance or Specification of Letters Patent.

Patented-Sept. 1, 1908.

cause the same to be weakened during the channel process. I accomplish this object by employing a rotary cutter for forming the shoulder on the edge of the sole and a vibrating or reciprocating knife for cutting. the channel, each acting so that they will not cause any resistance to the feeding of the sole by the feed wheel, and so that the strain which is placed upon the sole by the feeding rolls will practically be no more than if said shoulder forming and channeling devices were not present.

For a more complete understanding of my invention reference is made to the accompanying drawing, in which,

Figure 1 is a front elevation of a sole channeling machine made according to my invention. Fig. 2 is an end view thereof. Fig. 3 is the detail view of the cutter operating mechanism.

In drawings a indicates the base of the machine having a frame a thereon in which shafts b and e are journaled, and a bearing piece 0 is pivoted at c to an upright a on the base, a continuation b of shaft I) being journaled in said bearing piece and connected thereto by what is commonly known as an Oldham Joint 19 which permits the two shafts to be moved out of alinement without their being disconnected. An idle pulley (Z is mounted on shaft 6 said pulley constituting one member of a clutch, the other member d being splined on the shaft 6 and being adapted to be moved into engagement with the member d by means of a hand lever d", or any other suitable means. Said pulley d is driven by a belt d from shaft at. The shaft 6 is provided at its end with a smooth faced feed roll 6, and a gear 6 is also mounted on said shaft 6 and is adapted to mesh with a gear I) mounted on the shaft 1), so that the latter is driven from the former. Shaft b is provided at its end with a feed wheel I)", the

surface of which may be burred or slightly roughened or corrugated to an extent which will not be sufficient to cause injury to the leather or between-substance when the sole is fed between it and the roll 6. A casing f is supported by and pivoted on a pin f, which is secured in the left hand side of the frame portion 60 so that said casing is adapted to swing towards the front on said pivot, as indicated in dotted lines in Fig. 2. Said casing is held in its normal position by a spring fastener f mounted in the frame, or by any other suitable locking means which is adapted to be readily disengaged. Slidably mounted in said casing f is a holder. gwhich is adapted to move vertically therein, said holder being provided at its lower end with a pair of rearwardly projecting ears g in which a shaft 9 is ournaled, a pulley 9 being mounted on said shaft. A cutter shaft 9 is also journaled in the upper end of the holder g, said cutter shaft having a pulley g mounted thereon and a cutter g, of suitable form,

having blades which extend longitudinally of its shaft, is mounted on said shaft at its left hand end, the front ends of the cutter blades being held closely adjacent the adj acent face of the feed roll b The pulley g is secured to a smaller pulley g which is driven by a belt at from pulley 00 on the driven shaft 00, and the cutter shaft g is driven from pulley g by a beltg A hand screw g is swiveled in the lower end of the holder g and passes through the bottom of the casing f and a spring 9 is interposed between the bottom of said casing f and the hand wheel g which is secured to the lower end of the screw 9 so that the holder is normally held. by the spring against a stop collar g on the screw, which is adapted to bear against the bottom of the casing. A sole guard h, of common form, is mounted adja cent the right hand edge of the feed roll 0, said guard being mounted upon a pin 72, which passes through the casing, a spring 72/ being adapted to hold the guard in a position adjacent the right hand face of the feed roll 6 and any suitable lever mechanism, as indicated at 71/ may be employed to draw the guard away from said roll I). i

The bearing piece 0 is provided with a dovetail groove or guideway 0, see Figs. 2 and 6, in which a knife support '11 is slidably mounted. Said support is of angular form having a depending front portion i in which a pair of vertical ways i are formed, see Fig. 4. A pair of brackets c are formed integral with the bearing piece 0 and a shaft j is journaled therein, said shaft having a pulley 'j thereon which is driven by belt a: from shaft :10. A bevel gear y' is mounted on one end of said shaft which is adapted to mesh with a bevel gear 7c, the latter being splined on a shaft which is journaled in two arms i integral with the support a, said arms holding said gear 70 from vertical movement. A slide m is mounted to move vertically between the ways i of support 91, said slide having secured thereto a rod to which extends upward through a yoke i mounted on the support t. A spring w is mounted on rod 14 and is interposed between the upper end of the slide m and the under side of the yoke i so that nut u on the upper end of rod u is normally held by spring w against the upper side of the yoke and the slide m is normally held in the position of Fig. 2. A shaft m is j ournaled in the lower end of said slide m, said shaft having a beveled gear m at one end which is adapted to mesh with a beveled gear k secured to the lower end of the shaft is. The shaft 1c is also journaled at its lower end, in an arm m which is integral with the slide m.

A guideway block a is provided having a sleeve n which projects from one side thereof, and is j ournaled in the lower end of the slide m, the inner face of said sleeve constituting the direct bearing for shaft m, andsaid sleeve being held from longitudinal movement in said slide by means of a nut n on the end of said sleeve, see Figs. 2 and 8. The front end of shaft m is provided with an eccentric pin m and the guideway block a is provided with T-shaped guide-ways n in which a knife holder 0 is slidably mounted and supported, as shown in Fig. 8. The knife holder 0 is provided with a projecting ear 0, see Fig. 10, said ear having a vertical slot 0 into which the eccentric pin m extends, so that as said shaft m is rotated said holder will be reciprocated. A knife p is ad j ustably secured by suitable clamping means in the knife holder 0, said knife having a eutting edge at its end which preferably comprises an edge portion p at the extreme end which is perpendicular to the shank of the knife, and an oblique portion 29 which is continued for some distance along the side edge of the knife from portion 1), see Fig. 13. The knife block a is adjusted by means of the sleeve n and nut 71, into various positions in which the knife p will be oblique to the surface of the feed roll 6 and to the plane of rotation of the cutter g, and the knife 10 is adapted to be adjusted longitudinally, so that its end edge p extends to a level between the faces of the feed rolls 0, b and when in its advanced position, to a point as near to the cutter blades as is the desired thickness of the between-substance. The knife is so positioned that when the holder 0 is reciprocated the knife p will also be reciprocated longitudinally. The position in which the knife is held is such that its central longitudinal line lies in, or close to the vertical plane which passes through the axes of the feed rolls, that is, the plane in which the axes of the feed rolls lie. The axis of the cutter also lies in this plane, so that both cutter and knife engage the work closely adjacent the point at which it is held by the feed rolls.

A vertical rod r is slidably mounted in the frame and said rod 1' is provided at its upper end with a longitudinal slot 1", the upper portion of said. slot extending obliquely of the rod. The support i is provided with a projecting pin i which is normally located in the extreme upper end of the oblique portion of said. slot r, so that when said rod is forced vertically upward, said support i will be moved to the left in its guideways c, as indicated by the dotted position of Fig. 7. Said guideways c are preferably parallel to the position in which the knife 10, and knife holder guideways n are usually adjusted, so that when the support 'i is moved to the left it will move the knife longitudinally and draw it up from the face of feed roll 6. A sleeve 9 is mounted on the rod r and is provided with a projection q at its upper end, which projection is adapted to engage a pin 9 which is secured on the slide 9 near the upper end thereof. A pin 0 is rigidly mounted to the front end of the bearing piece 0 and extends through the slot 1". A spring 1' is mounted 011 the lower end of the rod 1* between the base of the frame a and a hand wheel 1" on the lower end of the rod, so that said spring normally acts to hold said rod in its lowest position. A pin g is secured in the sleeve 1 and a pin r is secured in the rod 7* and forms a support for the lower end of the sleeve g. A foot operated lever s is pivoted in a position to engage the pin g and a foot operated lever 25 is arranged to engage the pin 1. With this arrangement, if it is desired to draw the knife out of the work, the foot lever t is operated so as to lift the rod 1, and, as the rod is forced upward; the knife will be moved upward and to the left, as before described.

The sleeve Q will be lifted simultaneously with the rod 7" when the lever t is operated, and the projection q of the sleeve is so arranged that when the knife p has been moved outwardly and upwardly as far as possible, so that the pin i will be in the vertical portion of the slot 1, the projection will engage the pin on the slide g, causing the cutter g to be lifted against the action of the spring 9. Immediately after the projection q engages the )in g the pin 0 on the bearing piece 0 will be engaged by the rod 1" at the lower end of the slot 1', so that the whole bearing piece 0 will be swung upward about the pivot 0 upon further upward movement of the rod. In this way the feed roll I) will be lifted out of engagement with the work which may be held between it and the roll 6. If it is simply desired to lift the cutter g, the other foot lever s will be operated, causing the sleeve q to be moved upwardly, so that its projection g engages the pin g. The latter lever s is ordinarily only used while the sole is being channeled or fitted, it being desirable that the cutter be directly under the control of the operator, while the other lever is ordinarily used only when it is desired to remove or insert the work. The spring 9 permits the cutter to yield automatically under abnormal conditions, as when the sole is unusually thick or hard.

In operation, when a sole is to be channeled or fitted, the lever i will first be operated, lifting the cutter g, feed roll I), and knife 1), so that the sole may be readily inserted between the feed rolls b and c, with its edge resting against the edge guard h. The cutter y will be rapidly rotated and the knife p will be rapidly reciprocated when the parts are driven and, as the raising and lowering means is entirely independent of the cutter and knife operating means, it will be apparent that the knife and cutter may be raised and lowered while they are being driven, The cutter is adapted and arranged to engage the upper side of the sole adjacent its edge and form the usual shoulder or recess on the edge of the sole. As shown, the diameter of the path in which the cutting edges of the cutter blades move is less than half the diameter of the upper feed roll I). As it is usually desirable to form a vertical or nearly vertical shoulder, at the inner end of the cut made by the cutter blades, as shown in Fig. 12, these blades move below the roll 6 at their front ends, or ends adja cent said roll, passing up behind it at points a short distance to one side of the vertical lane of the cutter and roll axes. As the eather usually yields somewhat, so that the roll may sink into it to a slight extent, it follows that the sole is pressed down by the roll closely adjacent the point at which the cutter blades emerge therefrom to remove a chip, so that the leather is pressed or held down throughout practically the entire length of the chip, and, as above stated, the ends of the cutter blades move closely adjacent the adjacent or rear side of the roll, so that the leather is also held down closely adjacent the point at which the chip is to be severed at its end. The roll thus cooperates with the cutter in performing at least two important functions :first in preventing the cutter from lifting up the sole and cutting too deep a shoulder, and second in holding down the leather closely adjacent the point at which each chip is to be severed at its inner end, so that the ends of the cutter blades and the roll have practically a shearing action in cutting away the chips at their inner ends. Without such cooperation most of the chips would be left hanging at the upper edge of the shoulder. The effective cooperation of the roll and cutter which will enable the cut ter to cut away the chips at their ends is enhanced by the employment of a feed-roll having a practically continuous surface, as is the knurled or serrated surface which is employed, as distinguished from a roll having prongs or spurs, which actually penetrate the sole. That is, there is nothing to prevent the roll from pressing down the leather firmly at its edge next the cutter throughout its arc of contact.

The knife p, by being reciprocated longitudinally, will make a chisel like and also a slashing or drawing out in the sole, and. as the sole is fed, will form a slit or channel in the sole in the position ordinarily required. The length of the reciprocations are preferably less than the depth of the channel so that at no time during the cutting operation is the knife totally withdrawn from the channel. This prevents the knife from getting out of the channel and enables a sharp turn to be made in the channel, as in going around a pointed toe, without cutting the channel flap.

In channeling about the toe, andparticularly when the toe is sharp, much difliculty has been experienced with prior devices on account of the fact that the edge engaging devices must cut through, or pass over much more space on the sole than the channeling device, so that latter is not cutting at all while the greater part of the edge portion about the tee is being operated upon. Moreover, as is known in the art, with certain prior devices there is liability of'the channeling knife passing too close to the edge, so that the between-substance is weakened. With my arrangement, however, these difliculties are obviated for the reason that the cutter shapes or shoulders the edge as fast as the sole can be fed to it without a material amount of force being employed to feed the same, the knife acting as a pivot upon which the sole is swung as the cutter passes about the toe. Furthermore, the reciprocating action of the knife forces the sole at all times firmly against the sole guard, and always in the direction of the line which is perpendicular to the edge of the sole at the point at which it is being engaged by the cutter. tion that the cutterdoes not oppose this action of the knife in forcing the sole against the guard, so that the possibility that the sole will be channeled too close to the vedge is very remote.

The feed rolls 6 and b are operated at a comparatively slow speed, the speed at which the sole is fed being proportioned to the rapidity of operation of the cutter g and knife I). The extreme end portion 19 of the cut ting edge of the knife is made vertical to the path of the knife, so that the channel will be cut to a uniform depth, it being so arranged that the sole will not be fed a distance greater than the length of edge portion 1) between each complete reciproca- It willbe observed in this connection. The greater portion of the cut is made, however, by the oblique and side edge portion 29 which gives the stock a drawing out as it is fed at right angles to the path of the knife against said edge portion 29 and as the knife is moved longitudinally, it will be apparent that neither the chisel cut or the drawing out will materially impede the feeding of the sole, as it would be impeded if the knife were held stationary. The cutter, moreover, is operated so rapidly that it will not materially retard the feeding of the sole, even if it is rotated against the direction in which the sole is fed. The result is that no force is applied to the sole due to the channel and shoulder forming devices,

which in more than an inappreciable degree tends to impede the feeding thereof, so that the slight roughness on the feed wheel 5 is ample to accomplish the rapid feeding of the sole. In this way no injury whatever is done to the between-substance, but the action of the rollers thereon is merely to compress it. The knife may be as narrow as in prior machines, so that a sharp turn in the channel may be made without difficulty.

The means shown for raising the knife obviate the common necessity of starting the channel from the edge of the sole, the knife and cutterbeing lowered into engagement with the sole after the latter has been placed in position.

To be able to raise either the knife or the cutter partly or wholly out of engagement with the sole is. also of importance, for in cer tain kinds of shoes it is-not desirable to have the sole channeled back of the shank, although it is desirable to have the shoulder on the edge formed entirely about the heel, so that the edge may have a uniform shape. To accomplish this result, the lever t may be moved far enough to lift out the knife with out raising the cutter, or if it is also desired to raise the cutter to some extent, to decrease the depth of the shoulder, the lever i may be pressed still further. This result may also be accomplished without raising the knife by operating the lever s. It will thus be seen that numerous new results may be accomplished with the above described machine. When it is desired to change or grind the cutter the spring pin f will be drawn out and the holderf will be swung for ward on its pivot f out of proximity to the feed rolls, so that the cutter may be readily removed and replaced.

In a sole channeling machine, a sole support, a feeding device having a sole-engaging face, and a shearing face extending therefrom, at an angle, means for pressing said engaging face against a sole to hold the same on said support, and a transversely r0- tatable edge-forming blade having a longitudinal cutting edge, and a shearing edge extending therefrom at one end, and movable about an axis approximately perpendicular to the plane of said shearing face, in a path extending transversely of said shearing face with its shearing edge in cooperative relation thereto, substantially as described. 7

32. In a sole channeling machine, a sole support, a roll disposed to ress the sole against said support, said roll aving a circular shearing face on one side at its edge, a transversely-rotatable, edge-forming knife, movable in a path of less diameter than the roll, eccentric thereto and in position to cooperate at one end with said shearing face, adjacentsaid sup ort, substantially as described.

33. In a so e channeling machine, a sole support, a roll having a peripheral sole-engaging face, with a continuous shearing face at one edge of said peripheral face, means for causing said roll to press the sole against said support, an edge-forming knife-having a longitudinal cutting edge and a shearing face at its end extending from said edge, means for moving said knife transversely in a path ex tending transversely of said shearing face of the roll with its shearing face in cooperative relation thereto, the axes of said roll and said knife being parallel and said shearing face of the roll and said shearing face of the blade being respectively movable in planes perpendicular to said axes, substantially as described.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
