Fig. 4 for the reception of an interlocking heel; When the lateral margins of the heel end of Fig. 2 shows in perspective the heel gage and the sole have not been previously reduced to a the sole-trimming mechanism of the machine considerable extent, as illustrated in Fig. 5, I equipped to trim the heel end of the attached have found it preferable to form a tab or chan- 55 nel entering portion 46 of. the sole, the tab having a rear face t8 and beveled lateral margins 5U extending forwardly to or approximately to the ends of the heel-breast line 52 of the sole 25. The tab 46 may be described as tapering rearwardly from the ends of the heel-breast line of the sole.

The face 55 (Fig. 4) at the rear end of the trimmed sole 2t is formed by a knife 54 (Fig. 1) which has a straight cutting edge 55 and is movable in a vertical path past the straight front edge 53 of a sole-supporting plate 6&3 upon which the heel end 2U of the attached sole 24 of the shoe is supported. The tab 46 (Fig. 5) is formed by a knife 52 (Fig. 2) comprising straight cutting edges 55, 55 which are offset lengthwise and widthwise from each other and are joined by beveling cutting edges 68, the knife being movable in a vertical path past the front edge 'lll of a sole-supporting plate l2, which has a shape corresponding to that of the continuous cutting edges 54, S8 and 6B of the knife 52.

Three interchangeable sets of cooperating knives 52 and plate l2, such as illustrated in Fig. 2, are provided to accommodate a run of shoes. It will be appreciated that since each set of cooperating knives 62 and plates 'l2 has to accommodate several different widths of soles, the beveled margins l) of the tabs d6 formed by the cutting edges 68 only extend to the sides of the sole in the case of the smallest sole to be operated upon by that particular set of knives and plates. When a sole larger than said smallest sole is operated upon by said set of knives and plates, narrow shoulders l@ (Fig. 5) against which the upper breast corners of the heel abut, are formed on the sole, the width of the shoulder varying in accordance with the width of the sole. The narrow shoulders of the finished shoe are not supported against drooping away from the shoe upper by the heel, and it is therefore desirable that the next larger set of knives 62 and plates i2 be used when the width of the shoulders becomes substantial.

The sole-reducing knife 54 or 62 is clamped by a screw 16 (Fig. 2) to a vertically reciprocating slide 18 of the commercial machine which is disclosed in said United States Letters Patent No. 2,053,295 and which is adapted to fit the heelseat portions of attached soles of shoes for the reception of ordinary Cuban and Louis heels.

The plate Si! or 'l2 is located and held in its operative position in guideways 80 (Fig. 2) of the machine frame 8l, in place of the crease plate (not shown) of the commercial machine, through the provision of a rod 82 which may be moved to the left as viewed in Fig. 2, b-y the operator, against the action of a spring (not shown) to withdraw a tapered end (not shown) of the rod from a correspondingly shaped recess (not shown) in the side of the plate, preparatory to removing the plate from the machine. In positioning the selected sole-supporting plate Ell or 'E2 in the machine the operator moves the rod to the left as above described and slides the plate rearwardly to its approximate operating position in the guideways S5. The rod 82 is then released and the plate 6%] or T2 is moved slightly lengthwise until the tapered end of. the rod is forced by the spring into the tapered opening in the side of the plate.

In order to position the heel end 2i! (Fig. 4) 22 (Fig. 5) of the attached sole 2dy 26, respectively, upon the selected plate 6) (Fig. l) or l2 (Fig. 2) the machine is provided with a centralizing slide 84 (Figs. 1 and 2) and a back gage 86 constructed and arranged to be engaged by the counter portion of the shoe upper. The construction and operation of the centralizing slide 84 and the back gage 85 which is substantially identical with corresponding mechanism of the machine disclosed in Said Letters Patent No. 2,053,295, will be described later. It will be noted that when the machine is operating upon interlocking work the heel gage 86 (Fig. l) comprises an extension block 83 (Fig. l) which is detachably secured to the front end of the heel gage of the commercial machine. The extension block 83 has secured to it a pin 85 which ts in a recess formed in the front end of the heel gage of the commercial machine and is held in said recess by a spring-pressed plunger 8l.

The commercial machine may be readily converted into a machine for trimming attached soles of shoes for the reception of interlocking heels 28. Such a change is quickly effected by substituting the knife 514 and the plate 52 when it is desired to trim the sole to the form illustrated in Fig. 4, or by substituting the knife 62 and the plate 'l2 when it is desired to trim the sole to the form illustrated in Fig. 5, in place of the crease plate (not shown) and the shoulder-forming knives (not shown) of the commercial machine, and by providing a modified gage, which will effectively measure the interlocking heel, in place of the heel gage of the commercial machine. Moreover, since the heel end of the sole is reduced by the vertically moving knives 54, 62, the horizontally moving cutter (not shown) of the commercial machine, which reduces the heel-seat portion of the sole by a beveling cut, is removed from the machine.

It will be noted that the plates 55 (Fig. l) "l2 (Fig. 2) are provided with beveled faces 35, 9E), respectively, against which the rear ends of outsoles of full length are forced by a U-shaped clamp 92 (Fig. 1) of the commercial machine. In operating upon short soles the clamp 92 is removed from the machine since the heel end of the sole is then effectively forced against the forward part of the plate Gti or i2 by clamps 93 which are practically identical with corresponding clamps of the commercial machine. The clamps 92 and 93 are yieldingly mounted upon a verticallymovableplungerMoperated by a treadle (not shown). In operating upon interlocking work a bulger (not shown) which is mounted upon the lower end of the plunger 24 of the commercial machine and which forces` the central part of the heel-seat portion of the sole through the U-shaped opening of the crease plate when operating upon attached soles of shoes which are to receive Cuban or Louis heels, is removed from the plunger.

The heel gage of the commercial machine comprises a table 96 (Fig. 3) upon which the Louis or the Cuban heel to Vbe applied to the shoe being operated upon is positioned attaching-face down. In order to measure a Louis heel al (Fig. 3) the heel gage is provided with an abutment 2B (Figs. 1 and 3) movable forward and rearward over the table 95, and a bar Ilm (Fig. 3) which may be swung about a fixed pivot |62 into its operative position shown in full lines or into its vertical inoperative position shown in dotted lines. The abutment 98 is secured through a screw-and-slot connection |92 to a slide |95 (Figs. l and 3) Which is movable forward and rearward in a T- shaped guideway E53 of the table 96 and is pivoted at its rear end to the upper arm I l() (Fig. l) of a yoke H2 pivoted on a bearing pin H43 secured tothe main frame 8| by a screw ||6. The

in the side of the slide.

yoke ||2 is normally urged in a clockwise direction as viewed in Fig.' 1 by a coil spring ||8 the lower end of which is secured to a stud |28 carried by the pin l I4 and the upper end of which is secured to a stu-d |22 `carried by the yoke H2. The lower arm |24 of the yoke ||2 is provided `with a gear segment |28 meshingwith a gear |28 supported by and pivoted upon a bearing pin |38 which is secured by av screw |32 to the main frame v8| and has a flange at its lower end. Mounted for rotation upon the bearing pin |88 and secured to the gear |28 `by a binding pin |34 is a stop |88 which has a spiral outer face |38 and has secured to it a stud |48. When the heel is removed from the heel gage, rotation of the stop |36 in a counterclockwise direction, as viewed in Fig. 1, and therefore forward movement of the abutment 98 under the action of the spring H8, is limited by the engagement of the stud |49 with a post |42 secured to the main frame 8|.

When it is desired to measure a Cuban heel (not shown) in the heel gage, the bar |88 is moved into its inoperative position shown by dotted lines in Fig. 3, and an abutment |44 is swung 180 from its inoperative position illustrated in Fig. 3 about a pivot screw |46 which passes through a recess in the abutment |44 and is threaded into a slide |41 (Fig. 2). The slide |41 may be moved forward and rearward to its operative position in the table 96 by turning a screw |49 (Fig. 2) which is threaded into the table and has a flange 5| fitting in a slot |53 The abutment |44 is held in its operative and inoperative positions `upon the table 95 by a spring-pressed detent |55 (Fig. 3) which rits in a recess of the table |41 and registers with an elongate'dgroove |51 formed at the under side of the abutment |44. In measuring the Cuban heel the concave breast of the heel is forced through mechanism above described against a convex face |48 of the abutment |44 by the movable abutment 98.

Rearward movement of the centralizing slide 84 and the back gage 86 is limited by the stop |36 through mechanism which will now be described, the stopbeing rotated to a predetermined operative position through the above-described mechanism in accordance with the size of .a heel positioned in the heel gage. The abutment 98 (Figs. `1 an-d 3) is engaged by the rear end of the rim of the attaching face of the Louis heel 91 (Fig. 3) and is moved rearwardly by the heel grasped in the left hand of the operator, until the heel can be placed attaching-face down upon the table 96 between the abutment 98 and the bar |88. When the heel is released by the operator the sliding abutment 98 is moved forwardly through the mechanism above described, the arrangement being such that the breast of the heel is forced against the bar by the sliding abutment 98 and is properly oriented upon the table. The heel thus clamped between the abutment 98 and the bar |08v has its attaching face measured lengthwise. When the heel gage is operating on Cuban work, the Cuban heel is measured in a similar manner, the breast of the heel being forced against the convex face |48 of the abutment |44 which is swung around 180 from the position shown in Fig. 3, as above described.

The back gage is Inovedforward and rearward along a straight groove |58 (Fig. 1) in the lower face of a stop `plate |52 which is slidable along a pair of opposed rectilinear guideways |54 of the machine frame 8|. The centralizing slide 84 which has work-engaging faces |56 (Figs. 1 and 2) is also mounted for movement along a pair of opposed guideways |58 which are parallel to and are positioned above the respective guideways |54. The centralizing slide 84 is normally urged forward against an upstanding lug |68 of the stop plate |52 by a pair of springs |62 (only one of which is shown) which are enclosed in recesses |64 of the centralizing slide 84 and engage the forward ends of rods |66 which t in the respective recesses and engage a ,lug |68 secured to the main frame 8|. When the machine is idle the back gage 86 is normally held in its advanced inoperative position shown in Fig. 1 in front of the stop plate |52 by a spring-|19, forward movement of the back gage with relation to the stop plate being limited by the engagement of a shoulder |12 of the back gage with the rear end of the stop plate. Extending through an elongated slot |14 of the back gage is a block |16 supported by a screw |18 which is threaded into the stop plate |52 and has an enlarged portion |88 located in a recess |82 of the block. A depending pin |84 is secured to the stop plate and rlts in a cylindrical recess |86 of the block |16, the arrangement being such that the block may be swung laterally with relation to the stop plate about the pin |84 within limits determined by the enlarged portion |89 of the screw |18.

As above described, the stop plate |52 is normally urged forward by the centralizng slide 84 which, in turn, is constantly urged forward by springs |62. In order to limit forward movement of the stop plate |52 the block |16, which is carried by the stop plate, has secured to it a depending rod |88, which when the block is moved forward to a predetermined position, engages the main frame 8|. The block |16 has a concave cylindrical face |88 which when the block is moved rearward engages the spiral face |38 of the previously adjusted stop |36 thereby limiting rearward movement of the stop plate and the back gage 85. Thecounter portion of the shoe is forced against the respective workengaging faces |56 of the centralizing slide, and as the shoe is forced rearward its rear end engages the back gage 86 forcing the same, together with the centralizing slide S4, rearward. As the back gage 85 is moved rearward by the shoe it engages the stop plate |52 and moves the same rearward until the face |98 of the block |15` carried by the stop plate |52 engages the stop |36. It will be clear that the position of the shoe in the machine depends upon the angular setting of the stop |36 which is connected through the above-described mechanism to the movable abutment 98 of the heel gage.

As above explained the heel gage of the commercial machine may be quickly modied so as to accommodate interlocking heels. Preparatory to trimming the rear end of the sole straight across, as illustrated in Fig. 4, for the reception of the interlocking heel, a platform or unit |92 (Figs. 1 and 3) is mounted upon the table 95. The platform |92 is provided at its under side with a slot |94 (Fig. 3) for receiving the bar |80 and has secured to it a depending pin |96 oonstructed and arranged to t in a recess |58 of the table 96. The platform |92 comprises a base portion 288 and a sole-supporting plate 282 having a depending flange 284 which rlts in a forwardly and rearwardly extending groove 206 of the base portion 288. 'Ihe heel-supporting plate 292 also has a laterally extending shoulder 2li) against which the rear end of the interlocking heel is forced, as illustrated in Fig. 1, by a finger 2 I 2 carried by the abutment 98. In order to vary the operative position of the shoulder 2|0 the plate 202 may be secured in different adjusted positions upon the base portion 200 through the provision of a screw 2|| which is threaded into the base portion and passes through a slot 2|3 formed in the plate. The finger 292 is curved transversely in accordance with the curvature of the channel 32 of the heel and may be swung to its inoperative position shown in Fig. 3 when the gage is equipped to accommodate Louis or Cuban heels or to its operative position shown in Fig. 1 to engage the bottom of the sole-receiving channel 32 of the interlocking heel 28 mounted upon the platform |92 and to force the heel against the shoulder 2 I0 of the platform.

When the heel-end of the attached sole of the shoe is reduced by the machine equipped with the knife 62 (Fig. 2) and the plate 'i2 to provide the tab 46 (Fig. 5) it is customary to support the heel upon a slightly different type of platform or unit 2|4 (Fig. 2) which is similar to the platform |92, but has a pair of abutments 2|6 which are engaged by the breast of the interlocking heel. The platform 2M comprises a base portion 2|8 which is identical with the base portion 200 of the platform |92, and a heel-supporting plate 220 having grooves 222 along which the respective abutments 2I6 may be set in diierent adjusted positions through the provision of the screw-and-slot connections 2213. When the interlocking heel has been placed upon the table 220 by the operator, an abutment 226 corresponding to the abutment 98 forces the upper breast corners of the heel against the respective abutments 2|6 in the same manner that the abutment 98 forces the breast of the Louis heel against the bar |06 (Fig. 3)` In order to vary the lengthwise operative positions of the abutments 2|6 the plate 220 may be secured in different adjusted positions upon the base portion 2|8 through the provision of a screw 225 which is threaded into the base portion and passes through a slot 227 formed in the plate.

It is desirable that the abutments 2|6 engage only the upper breast corners of the heel, and with such an arrangement it has been found that there is a tendency for the forward end of the heel when forced against the abutments 2|6 to rise out of the gage. Accordingly the plate 220 has secured to it a leaf spring 228 (Fig. 2) which is flexed upwardly by the lip of the heel positioned upon the platform, the spring holding the heel against the above-mentioned tendency to ride up over the abutments 2|6 and therefore to be forced out of its operative position in the heel gage. Interlocking heels may be effectively measured by the above-described mechanism illustrated in Fig. 2 when the sole-receiving channels of the heels are of substantially uniform depth.

The heel end of the sole of the finished shoe should extend to or almost to the bottom of the channel 32 of the attached interlocking heel 28 of the shoe 25. It is therefore desirable that when the interlocking heel is positioned in the kheel-measuring gage, as illustrated in Figs. 1 and 2, the stop |36 should be so positioned as to be engaged by the block |16 forced rearwardly by the shoe, when a transverse section of the attached sole of the shoe corresponding to faces 40 (Fig. 4) 48 (Fig. 5) is arranged in the path of movement of the cutting edge 56 (Fig. 1) of the cutter 54 or the cutting edge 64 (Fig. 2) of the cutter 62.

In order to position the abutment 98 (Fig. 3) in correlated position with the stop |36 to adapt the machine for operating upon Louis work, the movable abutment 98 is initially adjusted as above described with reference to the slide |06. It is undesirable to disturb this adjustment between the abutment 98 and the slide |06 When changing over to other types of work and, accordingly, the above-described separate gaging mechanism is provided to adapt .the machine for interlock work.

It will be appreciated that the distance between the face 40 (Fig. 1) or the face 48 (Fig. 5) formed upon the attached soles 24, 26, respectively, of shoes, and the rear ends of said shoes, is considerably less than the distances between heel-breast receiving shoulders formed upon attached soles of corresponding shoes which are to receive Louis or Cuban heels, and the rear ends of said corresponding shoes. Accordingly, in order that the same portion of the face |38 of the stop |36 used in connection with Cuban and Louis work may also be used in connection with interlocking Work, the extension block 83, which is secured to the front end of the back gage 86 equipped for Louis or Cuban work, has .a thickness 230 equal approximately to the average depth of the channel of the breastlock heel. As above stated, the extension block 83 may be quickly secured to the back gage 86 of the machine equipped for operating upon Louis or Cuban work by inserting a pin 85 carried by the block 83 in a recess of the back gage, the block being held in place by a spring-pressed plunger 81.

In order initially to adjust the machine so as to form a face 40 (Fig. 4) at the proper location lengthwise of the attached sole of the shoe, the operator, after positioning the interlocking heel upon the shoe, draws a heel-breast line across the sole of the shoe. A second line, which is parallel to said heel-breast line and is set back on the sole a distance equal to the depth of the channel 32 of the heel 28, is then drawn across the sole. The operator then forces the shoe against the centralizing slide 84 and the back gage 86 until said second line on the sole is in alinement with the front edge 58 of the plate 60. In positioning the shoe as above described the block |16 is moved rearward to a predetermined position through the above-described mechanism. The screw 2| which secures the plate 202 to the base portion 200 of the platform |92 is then released and the heel is positioned upon the plate 202 with its rear end in engagement with the shoulder 2 0, the gaging finger of the abutment 98 engaging the bottom of the sole-receiving channel 32 of the heel, as illustrated in Fig. 1. While retaining the shoe in the above-mentioned position the operator slides the plate 202 of the platform |92 rearward with reference to the base portion 200 of the platform until the face |38 of the stop |36 has been swung into forced relation with the face |90 of the block |16. The screw 2|| is then tightened to secure the plate 202 in its proper adjusted position upon the base 200.

In order initially to adjust the machine equipped with the attachment illustrated in Fig. 2 for operating upon interlocking work, the operator, after positioning the interlocking heel 28 upon the shoe, draws a heel-breast line across the sole of the shoe. The shoe is then forced .against the centralizing gage 84 and the back gage 86 until the said line is in alinement with the latarrasa-a2 eral offset portions of the front edge of the plate T2, The shoe thus positioned will have moved the block H6 rearwardto a predetermined position. The screw 225 securing the plate 220 to the base portion 2l8 oi"` the platform 2|4 is then loosened and the interlocking heel 28 to be attached to the shoe is positioned upon the plate with its breast in engagement with the abutments 2l6. `The plate 220 is then moved rearward with relation to the base portion 2 I8 of the platform 2M, the rear end of the heel forcing the abutment 225 rearward until the stop |36 has been swung into forced relation with the face l 90 of the block |16. The screw 225 is then tightened to secure the plate 220 and the base portion 2 I8 of the platform 2 I4 to each other.
