The operating parts of the machine are supported by a standard 44 (Fig. 1) upon which a table 46 is adjustably secured. Bolted to the forward end of the table 46 is a bifurcated bracket 48 which, through the provision of a bolt and nut connection 49, is secured to a depending flange 58 of a housing 52 within which a cutter-operating slide 54 is reciprocated. The end of the slide 54 is pivotally connected to an eccentric strap 56 driven by an eccentric 58. The eccentric 58 is keyed to a shaft 83 upon which is mounted a pulley 62 (Fig. 2) driven by a belt 64 from, for example, an electric motor 66 (Fig. 1).

In order to support the knife 32 which is thin and narrow and to tilt the same relatively to the support in order to form the heel-breast receiving shoulders 33, 3! the illustrated machine is provided with a rocking beam 38 (Fig. 3) mounted upon a bored bearing sleeve I8 (Fig. 2) which is secured to the housing 52 by a screw I2. Secured to and extending forwardly of the beam 68 is a bracket I4 which serves as a support for the guide members 34, 35. Slots I5 (Fig. 5) and I8 of the guide members 34, 35, respectively, are of suitable size to receive the strip knife 32 and to flex the same to curve its cutting portion 38. To insure that the cutting portion 38 shall not be deformed substantially by the work during the sole-trimming operation a brace 88 which is secured to the bracket I4 engages the convex side of the knife.-

The curvature of the trimming portion 38 of the knife 32 may be changed after releasing the brace from its clamped position with relation to the bracket M, by pivotally adjusting the guide member 35 about a pin 82 (Figs. 3 and 5) carried by a slide 33 which may be adjustab-ly secured in different positions along a guideway 84 of the bracket I4. Such pivotal adjustment is maintained through the provision of a set screw 85 which is in threaded relation with the slide 83 and passes through an arcuate slot 88 in the guide 38. After the adjustment has been made the brace 80 is again moved into engagement with the convex side of the knife 32 and is clamped to the bracket I4. The slide 83 may be adjusted heightwise relatively to the guideway 84 through the provision of a screw and slot connection 35 (Fig. 2).

The lower end of the knife 32 is secured to the operating slide 54 by a clamp plate 90 which is secured to the arm by a screw 92, the knife extending through the bore of the bearing sleeve '10 and engaging within the slots I8, 78 of the guide members 34 and 36, respectively. In order readily to replace a dull cutting section 38 of the knife by a sharp cutting section the knife has the form of a coil which is wound around a drum 94 (Fig. 2) supported by an arm 95 of the bracket I4. A sharpened'length of the strip knife 32 may be readily unrolled by releasing a clamp screw 98 carried by an angle arm I80 secured to the bracket I4 and pulling the knife lengthwise against the pressure of a friction spring (not shown) through the slots I6 and I8 and through the bore of the bearing sleeve Ill. The blunt portion of the lower end of the knife is then easily broken 01'1" preparatory to clamping the knife to the operating arm 54.

The shoe 28, the attached sole 22 of which is to have its heel-seat fitted for the reception of a heel 24, is mounted bottom side up upon the support 40, the heel portion of which has a shape similar to that of the heel portion of the inside of the shoe. The sole is clamped securely to the support 40 just forwardly of the heel-breast line I06 of the sole by a pair of opposed arms I82 (Fig. 7) of the clamp 45 which is carried by a-bracket IE4. 5

The shoe supporting and guiding mechanism is mounted upon an upright rod or post I88 (Fig.

which is slidably mounted in a forward extension I ID of the standard 44 and is normally urged upwardly by a spring M2, the lower end of the 10 spring being connected to a treadle I I4 which may be depressed for the removal of a shoe from the machine. In order to limit the upward movement of the rod I08 under tension of the spring I II] the rod is provided with a collar I I6 constructed and 15 arranged to engage the forward extension H8 of the frame of the machine.

An angular member II8 (Figs. 1 and 3) is secured by bolts to a plate I 28 which is formed integral with or is rigidly secured to the upper end of 20 the rod I88, a pair of guide rollers I22 (Fig. 3) being mounted upon the upper surface of the angular member H8 through the provision of screws I24. One of the rollers I 22 is of suitable width to fit within a U-shaped slot I26 formed 25 in a slide plate I28, the rollers I22 being suitably spaced to include between them a U-shaped rib I35 of the slide plate I28. A cover piece I 32 bridges the space between the rollers I22 and retains the plate I23 which is movable in a U-shaped 3o path, upon the angular member I I8.

Lateral adjustment of the support 48 relatively to the sliding plate I28 may be readily effected by moving the pedestal along a dovetail guideway I42 (Fig. 3) of the support bar I04 after re- "35 leasing a clamp screw I44 (Fig. 2). In order that the support 48 may be angularly adjusted relatively to the plate I28 in directions indicated by arrows I34 (Figs. 2 and 3) thereby to vary the angle of the beveling out 26 by which the heel- (40 seat portion 28 of the sole is reduced, the support 48 is provided with an arcuate depending portion I36 constructed for sliding engagement along an arcuate guideway I31 (Fig. 3) of a pedestal I38.

A screw I 40 which passes through split upper 45 portions of the pedestal I38 clamps the support 48 rigidly to the pedestal and may be released to permit angular adjustment of the support relatively to the pedestal. By providing the above adjustments the shoe may be accurately posi-='50 tioned upon the support 48 relatively to the trimming portion 38 of the knife. The plate I28 may be replaced by another plate having a rib I38 of a different shape in accordance with the shape to which the heel seat is to be trimmed. 55

During substantially the entire heel-seat reducing operation the overlasted counter portion I45 (Fig. 8) of the upper of the shoe 28 is held by the spring II2 against the bottom face I45 (Fig. 3) of the guide member 34 which therefore 60 also serves as a guard. The top face I48 (Figs. 4 and 5), as well as the bottom face I46, of the guide member 34 substantially merges with the sides of the strip knife 32 which projects from the forward portion of the guide member. The lower portion I58 (Figs. 4 and 5) of the guide member 34 extends beyond the cutting edge of the knife 32. The bottom and the top faces I46 and I48 of the guide member 34 thus operate as a plow, progressively raising the margin of the 'ZO heel-seat portion of the sole from the overlasted counter portion I52 of the shoe as the shoe mounted upon the support 40 is moved in a U- shaped path to form the beveling cut 26.

Before the guide member 34 operates as above '75 described the heel-breast receiving shoulder 30 is formed to permit the guide to be inserted between the overlasted counter portion I45 (Fig. 8) ofthe upper of the shoe and the marginal portion which is to be removed from the sole- The position of the heel-breast receiving shoulders 30, 3| is determined by a mark which has been previously drawn across the sole along the heel-breast line I06. The heel-breast receiving shoulder 30 is formed by causing the narrow strip knife. 32 to face downwardly toward the sole as illustrated in Fig. 4 as the shoe is raised with the support 40. The trimming section 38 of the knife is tilted to cause its cutting edge to face downwardly by rocking the beam 68 in a counterclockwise direction (as shown in Fig. 4) about the bearing sleeve 10. Such rocking movement is effected by actuating a two-way treadle I54 (Fig. 1) pivotally connected to a rod I56 which is universally connected to a lug I58 secured to the beam 68. As

the trimming section 38 of the knife finishes the shoulder-forming cut the operator moves the treadle I54 to a neutral or horizontal position such as is illustrated in Fig. 1. The portion I50 1 (Fig. of the bottom face of the guide which projects forwardly of the cutting edge of the knife engages the overlasted counter portion I45 of the shoe upper at the end of the shoulderforming operation and prevents the knife from injuring the shoe upper. After the heel-breast receiving shoulder 36 has been formed the heelseat portion of the sole is reduced as above described, the shoe being moved in a U-shaped path past the trimming portion 38 of the knife, the forward or plow portion of the guide 34 progressively engaging within the rand crease of the shoe as the shoe is moved in the U-shaped path.

When the trimming out has progressed to a point located adjacent to the opposite end of the heel-breast line I66 the operator by tilting the treadle I54 moves the beam 68 in a clockwise direction to cause the trimming portion 38 of the knife to face upwardly and lowers the shoe by stepping on the treadle II4 thereby to form the heel-breast receiving shoulder 3|.

When the beam 68 is in neutral position a spring-pressed plunger I62 (Fig. 5) carried by the same engages within a notch I64 formed in the bearing pin under which circumstances the cutting section 38 of the knife 32 is in position for making the beveling out. When the knife is in position to cut the heel-breast receiving shoulders and 3I the plunger I62 engages within notches I66 and I68, respectively, of the bearing sleeve 10. By providing the above detent means the operator may quickly swing the cutting section 36 of the knife from one of the three positions to another.

The trimming portion 38 of the knife may be initially adjusted relatively to the support in directions indicated by arrows I10 (Figs, 2 and 3) by sliding the table 46 along a guideway of the standard 44. Such adjustment may be readily effected by first releasing a set screw I12 which is in threaded relation with the standard and passes through an elongated slot I14 in the table 46 and then turning a hand screw I16 (Fig. l) which is rotatably mounted in a lug I18 of the standard and is in threaded relation with the table. After the proper adjustment has been made the set screw I12 forces the table 46 into binding relation with the standard 44.

The trimming portion 38 of the knife may be swung into proper adjusted position relatively to the support 40 by turning an adjusting rod I80 having right and left threaded portions which are screwed into swivels I82 and I84, respectively. The swivels I82 and I84 are pivotally connected to a rearwardly extending arm of the housing 52 and to a bracket I86 secured to the table 40, respectively.

In order rigidly to secure the shoe 20 upon the support 40 during the sole-trimming. operation the machine is provided with the clamp 42 comprising clamping arms I02 (Fig. '7) which are pivotally connected. to opposite ends of a bar I86, respectively. The bar I86 is pivotally secured to the upper end of a plunger I 88- one side of which is provided with a rack I90 constructed and arranged to mesh with a segmental gear I92 operated by a removable 1ever I94. A Horton clutch prevents the plunger I 88 from being urged upwardly under operating pressure of the arm I89 until a ball I96 which engages the plunger is forced downwardly against the pressure of a spring I98 by a release lever 200. When the plunger I88 is in raised position the arms I02 may be swung laterally to permit the shoe to be placed upon the support 40. A pair of spring-pressed plungers 202 engage notches 204 of the respective arms 162 to retain the same in vertical position. Since the bar I86 is pivotally secured to the plunger I88 the arms I02 may swing to equalize their pressure against the shoe. The bar I86 is normally held in horizontal position by a spring-pressed slide 206 which is constantly urged upwardly by a spring against the under surface of the bar I86. It will thus be clear that as the operating arm I94 is rotated in a counterclockwise direction the arms I02 clamp the sole against the support 40, the ball I96 operating to prevent the arm I94 from releasing the shoe until the ball is forced downwardly by the release lever 200.

In order to perform the heel-seat fitting operation the operator, after making the proper adjustments and after marking the heel-breast line I66 on the sole, lowers the support 40 and positions the shoe bottom-side up upon the same. The sole is then clamped to the support by the arms I02 as the operator moves the lever I94 in a counterclockwise direction. The cutter is then tilted to the position illustrated in Fig. 4 and the shoe upon the support 40 is swung around to the starting position. As the shoe upon the support 40 is raised under pressure of the spring II2 the cutting edge of the trimming portion 38 of the knife enters the sole along one end of the heel-breast line to form the heel-breast receiving shoulder 30, the upward movement of the support 46 being limited by contact of the overlasted counter portion I (Fig. 8) of the shoe with the portion I (Fig. 5) of the guide member 34. The beam 68 is then turned to its neutral position, illustrated in Fig. 5, and the heel portion of the shoe is moved in a U-shaped path past the cutting portion 38 to reduce the heel-seat portion of the sole by the beveling out 26 (Fig. 8). When the beveling out has progressed forwardly of the sole to a point just rearwardly of the opposite end of the heel-breast line Ififithe operator tilts the beam 68 until the plunger I64 engages within notch I66 thus causing the cutting edge of the trimming portion 38 of the knife: to face upwardly. The treadle I4 is then depressed to cause the trimming portion 38 to-form' the heel-breast receiving shoulder 3| at" the opposite endof the breast line I06.
