l Claims.

This invention relates to machines for tting the heel-seat portions of attached soles of shoes for the reception of heels.

Preparatory to trimming the heel-seat portions of attached outsoles of shoes or sandals having open backs, for the reception of heels, by the use of a machine of the general type disclosed in United States Letters Patent No. 2,099,698, granted November 23, 1937, on an application filed in the` name of Ralph S, Megathlin, for eX- ample, it is desirable to centralize the shoe in the machine `hy utilizing the rear part ofthe insole of the shoe.

The illustrative machine, as in the case ofthe l machine disclosed in said Letters Patent, comprises a crease plate having a U-shaped opening,

means including a loulger for-forcing the central part of the heel-seat portion of the attached outsole of a shoe through said U-shaped opening and beyond one `side of the plate, and a knife movable in a predetermined path along said one side of the plate to reduce the heel-seat p-ortion In order effectively to centralize shoes having open loacks, there is provided, in accordance with a feature of this invention, a gage which is normally arranged in approximate engagement with said one side ofthe crease plate and in the path of movement orf the heelseat-reducing knife and which -is of suitable shape to be engaged by and to 'centralize the rear portion of the insole of the shoe thereby centralizing th heel-seat portion of the outsole upon the crease plate, said gage being movable away from the path of movement of the knife so as to permit the knife to bemoved in said path.

The various features of the invention will be understood and appreciated from the following description readin connection with the accompanying drawings, in which Fig. 1 is a perspective View, partly in section and partly broken away, of a portion of an illustrative heel-seat `fitting machine embodying the invention;

Fig. 2 is a perspective view, partly ybroken away, of `a portion of a centralizing gage for locating a shoe widthwise in the machine.

Figs. 3, 4 and 5 are sections on line III--III A of Fig. 1 during threesuccessive stages of the of its outsole fitted -by theahove machine, a heel which is later attached to the shoe loeing shown in dash lines.

The illustrative machine is describedy with reference to reducing the heel-seat portion i8 (Figs. 3, 4 and 5) of an attached outsole 2E! of a Shoe` or sandal .22, which is mounted upon a last 24 and has an open back or rearend, for the reception of a heel 2t (Fig. 6), and comprises a crease plate 28 havinga U-shaped opening Sil (Fig. 1), a hack gage 3i and fingers 3d constituting a V-shaped centralizing gage, for positioning the heel-seat `portion i3 of the outsole of the shoe lengthwise and widthwise, respectively, upon the crease plate, a clamp 3S (Figs. 3, 4 and 5) `for forcing the margin of the heel-seat portion of the outsole against the upper side or face 38 (Figs. l and 5) of the crease plate, a Ibulger it (Figs. 3, 4 and 5) for forcing the central part of the heel-seat portion of the outsole through 'the U-shaped opening 3i) and below a lower fiat side or face 'i2 of the crease plate, vertically movable knives fill for for-ming heel-breast receiving shoulders i5 (Fig. 6) upon the outsole of the shoe, and a knife lli movablealo-ng the lower face i2 0f the crease ,plate for reducing the heelseat portion oi the outsole and cooperating with the shoulder-forming knives 44 to form a heelseat tab (il. The centralizing lingers 34% are `pivotally mounted upon a side 48' which, if desiralole, maybe used to centralize shoes having complete counter portions, such shoes being hereafter referred to as regular work.

The illustrative machine, kwith the exception of the centralizing ngers 34 and the forward portion of the slide il? which supports the fingers, is practically identical with the 4machine disclosed in said United States Letters Patent No. 2,099,698 which, together with United States Letters Patent No. 2,053,295, granted September 8, 1936, on an applicationled in the name of Fred L. MacKenzie, should be referred to for a complete understanding of the construction and operation of the machine.

It will -be appreciated that the shoe 22 which has an open back cannot be effectively centralized loy faces 5d of the slide t8 which, when the machine is operating upon regular work, are en gaged -by the rear vcounter portion of the shoe. Accordingly, the slide til is provided with bores 52` (Figs. 1 and' 2) for receiving trunnions 54, respectively, of the centralizing fingers Si which are normally urged upward against or in approximate engagement withthe lower side 42 of the crease plate 28 `by springs 55 (Figs. Zand 3) which fit in pockets 53 of the slide 48 and eni' gage the lower faces of the iingers. The workengaging faces 68 oi the fingers 34 are arranged considerable distances aheadof the work-enby a pair of springs @il until it engages an upstanding flange 56 of a stop slide S8 which is mounted for movement along a guideway l@ of the machine frame. Pivoted for` movement through a small arc on a pin l2 carried by the stop slide 63 is a block 'lllto which a depending rod 'i6 is secured. Forward movement of the stop slide 68 under pressure of the slide 48 is limited by the engagement of the rod 'i6 'with the frame (it of the machine.

The back gage 32 is movable along a vertical guideway 'i8 of a `carrier slide @El which is supported by the machine frame and is movable along a gui-deway 82 (Fig. 1) at the under side of the stop slide @8. Secured to the back gage 32-is a pin @il (Figs. 3, 4 and 5) which is normally held in engagement with a shoulder 85 (Fig. 5) of the carrier slide il@ by a spring 35, the lower end of which embraces the pin 8d and the upper end'of which is fastened to the carrier slide ill). It will be noted that when the machine is idle the upper face 33 (Fig. 1) of the back gage 32 is approximately in alinement with the lower face l2 of the crease plate 28.

The carrier slide Sil is provided with a slot .qll through which the block lli passes, and is constantly urged fo-rwardwith relation to the stop slide $8 by a spring 92, forward movement of the carrier slide Sli with relation to the stop slide 68 being limited by the engagement of a flange 93 of the carrier slide with the rear end of the stop slide.v

The shoe is placed in the machine with the heel-seat portion i8 of its attached outsole 2f! overlying the crease plate 28 and its insole gli in engagement with the centralizing fingers 3d. The operator then forces the shoe and therefore the lingers fllcarried by the slide 48 rearwardly until the rear end of the insole 9d engages the back gage 32, the fingers during such movement centralizing the shoe. As the operator continues to move the shoe rearward the carrier slide lli) engages the upstanding flange S6 of the stop slide B8 which is moved rearward under pressure of the shoe until the .block lll pivoted to the stop slide engages a spiral face 96 of a cam S8.

The cam 98 is operatively connected to a movable abutment of a gage (not shown) constructed and arranged to measurelengthwise the heel to be attached to the shoe, and may ybe swung into different operative positions in accordance with the length of the heel measured in the gage. The construction and arrangement. of the heel gage and the shoe-positioning mechanism are such that when the heel-seat portion i8 of the attached outsole 2li of the shoe or sandal has been trimmed, the heel, which has been measured in the gage and is correctly positioned upon the shoe, will have its breast in snug engagement with the heel-breast receiving shoulders l5y formed upon the outsole.

After the shoe has been positioned in the machine the operator depresses a treadle (not shown) causing the clamp 36' to force the margin of the heel-seat portion i8 of the outsole 26 positioned upon the crease plate 28 against the face 3S of the plate, as shown in Fig. 3. When the treadle is further depressed a one-revolution clutch' (not shown) is tripped causing the bulger 1li! to force the central part of the heel-seat portion of the outsole 2B through the U-shaped opening Si) and below the lower face 42 of the plate 23, as shown in Fig. 4, and simultaneously therewith causing the shoulder-forming knives 44 to be moved to their lowered positions past the forward edges 99 (Fig. 1) of the crease plate 28 to form the heel-breast receiving shoulders 115.

During the above movement the back gage 32 and the centralizing fingers 34 maintain their operative positions'in the plane of the lower face l2 of the crease plate 23, as illustrated in Fig. 4, the heel end of the shoe upper being depressed slightlyby the bulger di). As the machine continues to operate, the heel-seat reducing knife M moves forward with its cutting edge Ill@ in engagement with or approximately in engagement with the lower face d2 of the crease plate 23 to reduce the heel-seat portion i8 ofthe sole and to cooperate with the knives M to form the heel-seat tab 4l.

During the forward travel of the heel-seatreducing knife' l5 the back gage 32 is forced downward along the guideway 78 Vof the carrier slide 8U, and the centralizing'iingers 315i are swung downward about the common axis of t'he trunnions 555 away from the crease plate ,28 and out of the path of travel of the heel-seat-reducing knife d5 to their positions shown in Fig. 5. With the above arrangement it will be'clear that the back gage 32 and the centralizing fingers 34, which, when the machine is idle and while the shoe is being positioned in the machine are arranged in the plane of the lower face l2 of the crease plate, can be effectively engaged by the insoles 94 of shoes having open backs so asto locate the shoes accurately in the machine, and are movable away from the crease plate 23 so as to enable the heel-seat-reducing knife 46 to move along the under face of the crease plate 28 to reduce the heel-seat portion 18 of the attached sole 2Q of the shoe.
