HEEL SEAT FITTING MACHINE Original Filed May 26, 1932 5 Sheets-Sheet 5 Patented Nov. 13, 1934 1,980,369 7 HEEL SEAT, FITTING MACHINE Frank Barton, Leicester, England, assignor to United Shoe Machinery Corporation, Paterson, N. J., a corporation of New-Jersey- Application May 26, 1932, Serial No. 613,653. In Great Britain June 16, 1931. Renewed May This invention relates to machines for operating upon soles and is illustrated as embodied in a machine for trimming the rear portions of soles for the reception of heels.

It is sometimes the practice to fit the heel seats of soles for receiving heels such, for example, as wood heels of womens shoes, prior to the attachment of the solesto their respective shoe uppers. A machine which may be used successfully for this purpose is disclosed in British Letters Patent No. 305,276 and comprises a matrix plate having an opening formed therein and a work supporting plunger located directly beneath the opening and upon which the heel end of an unattached sole may be positioned, the plunger being mounted for movement to force the'heel seat part of the rear portion of the sole through the opening and above a face of thematrix plate. After the sole has been properlyv distorted, portions of the sole lying below the face of the plate are trimmed from the sole by a knife, the cutting edge of which moves over the face of the plate, thereby to provide a heel seat of substantially the same size as the opening formed in the plate.

An object of this invention is to provide an improved machine of the general type above described. In fitting the heel seats of soles of shoes, it is desirable to vary the sizes of the heel seats in accordance with variations in the sizes of the attaching faces of the heels which are to be secured to the shoes. Hence, the illustrated machine, in accordance with-a feature of the invention, is provided with matrix plates which are relatively adjustable to vary the size of. a U- shaped opening formed by the plates, according to the size of the heel seat desired, and a plunger comprising a member for clamping a sole against the plates and a bulger having a sole engaging face mounted for movement to force the heel seat portion of the clamped sole through the opening and beyond faces of the plates, and a cutter mounted for movement over the faces of the plates to remove the margins of theheel seat portion of the sole from the sole. The illustrated plunger is constructed andarranged to receive interchangeably one of a plurality of bulgers the sole engaging faces of which are of different sizes and shapes.

By providing a plunger constructed interchangeably to receive one of .a plurality of bulgers having sole engaging faces of various sizes and shapes, the operator may readily select a bulger which will effectively cooperate with the matrix plates when adjusted to fit a heel seat of. a de- 29 Claims.

sired outline, to form a predetermined bevel around the marginal portion of the heel seat.

-In the illustrated construction the clamping members are U-shaped and have upper beveled faces which, when the plunger is raised, engage complementary beveled faces formed on the matrix plates. In order to insure that the beveled faces of the clamping members will cooperate with the beveled faces of the plates when fitting heel seats of various sizes, the clamping members and the matrix plates are mounted for adjustment together and tothe same extent.

The illustrated machine is provided with a gage which is shaped and arranged to centralize the rear portion of the sole and is movable against a stop under pressure of a sole to position the same lengthwise in the machine. v In order to remove surplus material which has been trimmed from the sole from the operating parts of the machine, and in accordance with a further feature of the invention, the gage of theillustrated machine is automatically'operated in timed relation with the plunger for movement over the sole supporting surface-of the plunger after the plunger has been moved to a predetermined position away from the matrix plates;

In order to expedite the heel seat'fitting operation and to permit the operator freely to use both hands during such operation, the illustrated machine is provided with a single member shown as a treadle and operable to raise the plunger thereby distorting the sole and then automatically to trip a clutch which causes the-cutter to move over the surface of the matrix plates to trim the sole. I v

These and other features of the invention will now be described with reference to the accompanying drawings, in which a Figs. 1 and 2 show side and plan views respec tively of the illustrated ,machine, portions of which have been broken away in order better to show the construction thereof; I

Fig. 3 is a perspective View of a plunger of the illustratedmachine; Fig. 4 is a longitudinal verticalsection of a'portion of the machine, and shows .a solethe rear part of which is being trimmed in themachine; Fig. 5 is a sectional view takenalong line V--V ofFig.4; Fig. 6 is a sectional View of the plunger taken along the line VI-VI of Fig. 4; and

Fig. '7 is a perspective view of the rear part of a sole, the heel seat portion of whichhas been trimmed in the illustrated machine.

' The illustrated machine is described with reftrix plates 24 mounted for movement toward and away from each other and shaped to provide a U-shaped' opening 26 (Fig. 2) through which the heel seat portion or tongue 22 of a solepositioned in the machine bya gage 28 is forced by a plunger 27, the portion of the sole. remaining below upper faces 30 of plates 24 (Fig. 4) being severed from the sole by a cutter or knife 32,.the cutting edge 34 of which is mounted for'movement along the upper faces 30 of the plates 24.

The operating parts of the illustrated machine are mounted in a main frame 36 secured'to a suitable support (not shown) and provided with a curved guideway 38 shaped to receive curved T-shaped depending blocks 40 one of which is secured through screws 41 (Fig. 2) to each of the matrix plates 24. The forward inner corners of the plates 24 are cut away to provide the U- shaped opening 26 which has the same general outline as the heel seat of a sole to be fitted in the machine. The plates 24 are undercut around the opening, 26 to form side faces or walls 42 (Fig. 1) of theopening which are shaped to allow the central portion of the heel end of the sole to be forced by. the plunger- 27'through the opening 26 with a minimum amount of distortion of the sole. v

The curved guideway 38 of the casting 36 is concentric with reference to point 44 (Fig. 2) which is located-at the extreme end of the opening 26 formed by theplates 24 and about which the plates 24 may be adjusted at equal distances from and at opposite sides of a central plane 46 (Fig. 2) of the machine. In order to adjust the plates-24 about .the point 44 each of the plates 24 isprovidedwith a depending pin 48 (Fig. 1) pivotallysecured thereto and in threaded relation with a transversely extending horizontal screw50 rotatably mounted in the; casting 36 and threaded in opposite directions along different portionsthereof. Upon rotation of the screw 50 through" a hand wheel 52 (Fig; 2), the plates 24 may be pivotally-adjusted about point 44 as the blocks 40 screwed to the plates 24 are moved along the'curved guideway 38 to increase or to decrease the size ofthe opening 26 which is formed between the plates 24 and which determines the size towhich the heel seat of the sole is to be trimmed by the machine. To assist in guiding the plates 24 as they are pivotally adjusted, the extreme forward end portions of the plates are provided with slots53 (Fig. 2) which are concentrically arranged with respect to the'point 44 and through which extend studs 58 secured to the casting 36.

The work supporting plunger 27, which isconstructed to receive interchangeably one of a series of bulgers '54 of difierent sizes and has an upper sole engaging face 60, isimounted in a vertical guideway 62 (Fig. 1) of the frame 36 and. is located directly below the opening 26. The face of the illustrated bulger 54 is slightly beveled at its marginal portions. In order, however, to make a more pronounced bulge at the rear' end of the portion-of the sole forced above the faces 300i the plates 24, the rear edge of the bulger may be disposed substantially at right angles to the face 60.

The chosen one of the interchangeable bulgers 54 may be conveniently mounted upon and secured to' a vertically disposed slide 64 of the plunger 27 .through the tongue and groove arrangement 65 (Fig. 5). A latch 66 which is pivotally mounted upon a pin 68 carried by the slide 64 locks the bulger 54 to the slide 64, the latch normally being urged upwardly by a spring pressed plunger 70 inserted in a recess of the slide to cause a projection 74 of the latch to engage arecess 76 of the bulger 54. The slide 64 is enclosed within a sleeve 78 (Fig. 1) and is in threaded relation with arod 80 and is also in engagement with a flanged portion '79 of the rod upon which is mounted anadjustable hand wheel 82. The

sleeve 78 is supported at its lower end by a head 84 which is held in engagement with the sleeve 78 by a spring 86 encircling therod 80 and having its upper and lower ends in. engagement with the head 84 and the hand wheel 82 respectively. It will be noted that as the slide 64 is moved upwardly (Fig. 1) by a lever 88 pivoted on the cast ing at 90 and having a ball portion 92shaped and positioned to engage a recessedportion 94. of the slide 64, the sleeve 78 will be Imoved upwardly with the slide until its free movement therewith is impeded as will later be described.

The sleeve '78 has a head'96 upon which is mounted apair ofcurved clamping members 98, '100' which'are pivotally secured to the head by a pin 102, an end portion of which is in threaded relation with clamp member 100. .Thefpin 102 is provided witha cylindrical'portion 1040f suit-I able size to fit within a. recess in the .clamp meniber 98,.the members beingassembled'on the head 96 by inserting the pin 102 in an enlarged open-.- ing 106 at the underside of the head'96 and by thenscrewing thepin into the clamp member 100. The clampmembers 98, 100 taken together are U-shaped and surround the bulger v54 as well as conform generallyto the outline of the face 60 of the bulger.

It is desirable that the sole 20 be. clamped firmly between the plates 24 and the clampmembers 98, 100 as the bulger 54 is raised to move the heel seat portion 22 of the sole above' the faces or surfaces 30 of. the plates 24., Accordingly, the clamping members 98, 100 have, upper beveled faces 108 which cooperate with the beveled faces 42 of the matrix plates 24 to clamp the sole through the spring 86 and the mechanism above described, while the slide. 64 which carries the bulger 54 is being raised. Thebulger 54, which is mounted upon the slide, is. moved upwardly until its face 60 lies very slightly below the plane of the upper faces 30 of the matrix plates 24. Upward movement of the bulger 54 is terminated by a stop 110 adjustably mounted in the main frame 36 of the machine and positioned to engage the lever 88 when the face 60 of the bulger 54 arrives at a position slightly below the faces 30 of the plates 24; 7

In order to fit the heel seat portions of different soles for the reception of heels of different sizes and styles, tongues 22 of diiferent'shapes will be required. It is therefore desirable that the matrix plates 24 be adjusted relatively to each other general shape as the opening 26 but spaced from,

:the edges of the plates 24 at a distance approximately equal to the thickness of the sole being trimmed. In order to insure that the upper faces 108 of the clamping members'98, 100 will engage the beveled faces 42 of theplates for different adjusted positions of the plates and in order to construct the clamp members 98, 100 so that they will receive bulgers 54 of various sizes and will conform generally to the outlines of the faces 60 of different bulgers, the members 98, 100 are mounted for adjustment about a pin 102 the. axis of which passes through point 44.,

.In order to adjust the clamping members 98, 100 toward and away from one another each of the matrix plates 24 is provided with a depending pin 112 which fits intoa cylindrical opening of a laterally extending flange 114 of a corresponding clamping member, each of the clamp members 98,

100 being guided for pivotal adjustment by a screw 116 (Fig. 3) secured thereto and having an enlarged head shaped to engage an undercut circular guideway 118 formed in the head 96.

When the plunger27 is out of engagement with the matrix plates 24 (Fig. 1) the upper surfaces 108 of the members 98,100 are located slightly above the plane of the face 60 of the bulger 54, such adjustment being. effected by the spring 86 which forces the head 84 and the sleeve '78 upwardly with respect to the slide 64 until the head 84 engages theflanged portion '79 of the rod 80. The above adjustment permits the clamp members 98, 100 to force the sole against the plates 24 before the bulger 54 starts to cooperate with the plates to distort the sole. It will be noted that when the plunger 2'7 is in its lowered position, the clamp members 98, ,100 are located beneath the lower surface of the gage 28 which, as will later be explained, serves as an ejector for removing portions trimmed from the sole from the machine.

p In order to trim from the distorted sole 20 (Fig. 4) material lying below the upper faces 30 of the plates 24, thecutting edge 34'of the knife 32 is mounted for movement in contact with the faces 30 of the plates 24. The knife 32 is secured between a carrier 120 and a clamp 122 by a screw 124. The carrier 120 is guided for reciprocation in horizontally disposed forwardly and rearwardly extending grooves 126 formed in the frame of the machine and is pivotally connected to a rearwardly extending link 128 which is secured to an eccentric (not shown) connected to acne-revolution clutch (not shown).

In order to operate the lever 88 (Fig. 1) a housing 130 is pivotally secured to the same and encloses a spring 132, which is supported on a column 134 screwed into the lower end of the housing 130 and has its upper end in engagement with a head portion 136 of a treadle'rod 138. To insure that the plunger 27 will effectively press the heel seat portion of the sole 20 through the opening 26 formed in matrix plates 24, the spring 132 is of substantial strength.

For assisting the operator in positioning the sole 20 relatively to the plunger 2'7 and to the opening 26 formed in the matrix plates 24, the illustrated machine is provided with the work gage 28 which is positioned below the matrix plates 24. The gage 28 comprisesa fiat bar 140 extending forwardly and rearwardly of the machine and has at itsforward end a bifurcated portion 142 which centralizes the rear part of the sole in the machine and is located slightly rearwardly of and just above the plunger 27 (Fig. 1) when the sameis in its lowered position.

To position the sole 20 lengthwise in the machine, the gage 28 is provided with a depending portion .144 which may be moved rearwardly against an The gage 28, in addition to locating soles in the machine, serves as an ejector to push waste material, which has been trimmed from the sole and usually rests upon the plunger 27, from the machine.

with bifurcations 150 each of which carries a threaded stud 152 upon'which is mounted a pawl 154 free to swing in a rearward direction about the stud 152 but prevented from moving in a forward direction because of contact between a face 156 (Fig. 1) of the pawl 154 and a cooperating face 158 of the corresponding bifurcation 150. i

To move the gage 28 forwardly of the machine against the pressure of the spring 148 to eject from the machine chips trimmed from the sole, the machine is provided with a bifurcated link 160' pivotally mounted on a shaft 162 extending transversely of the machine at its rear portion. The link 160 carries projecting pins 164 at its upper ends, the pins 164 being constructed and arranged to engage respective pawls 154 at predetermined intervals to move the gage 28, which may also be referred to as an ejector or a combined gage and ejector; forwardly of the machine. To operate the link 160, the latter has connected to it a tensioning spring 166 which extends forwardly of the machine and is secured at its'forward end to a pin 168 fixed to the machine'frame. In order to move the bifurcated link 160 to a position rearwardly of the pawls 154 the lever 88 is provided with a rearward extension which carries a stud 170 arranged to engage forward faces 172 of the link as the treadle rod 138 is moved downwardly to raise the plunger 27. The stud 170 carried by the lever 88 causes the link 160 to move in a rearward direction about its shaft 162 to position the pins 164 behind the pawls 154 of the gage 28, the pawls moving freely on the studs 152 as the pins 164 swing rearwardly.

To hold the bifurcated link 160 at its rearwardmost position until the plunger 27 has been lowered to a position .in which the upper beveled faces 108 of the members 98, 100 are located slightly below the bottom face of the gage 28, a forwardly extending finger 1'74 is freely mounted on a rod 176 which extends transversely of the machine. The finger 174 is provided at its under side with a notch 178 for engaging an extension 180 carried by the bifurcated link 160, when the latter has been urged rearwardly by the pressure of the lever 88, andthus maintaining the link160 in its rearward position until the finger 174 is lifted. The finger 174, which is normally urged downwardly by a spring 182, is lifted as the rod 138 is allowed to rise by the stud 1'70 carried by the lever 88, the stud 170 operating against the forward end of the finger 174 to lift it away from engagement with the extension 180 of the bifurcated link 160. As soon as the lever 88 is lifted to release the bifurcated link 160, the latter moves forwardly of the machine about the shaft 162 to strike againstthe pawls 15 4 thereby causing the gage to move forwardly of the machine 7 In order to operate the gage 28 for this purpose, the rear end of the gage is provided ,to eject from the. machine asoletrimming'or chip which rests on the plunger .27. The 'treadle rod 138 is normally heldin raisedposition, the'upward movementof the same being limited by a stop184 adjustably mounted upon the lever 88 and positioned forengagement with the'machine-frame. The stop 184 is adjusted .toengage the machine frame, when thebeveled portions 108-of:the*memv bers 98, 100 have i been; lowered tov a position slightly below the undersurface of the gage. 28.

The one-revolution clutch (not shown) whichactuates the cutter or knife 32 may be tripped by hand if desirable but, in order to expedite'the trimming operation and to enable the operator freely to use both hands in presenting work to the machine, the illustrated machine is provided with an automatic trip device for the clutch (not shown). The operationof the clutch is controlled bythe treadle rod 138, the head 136 of the rod being providedwith a pin .186 which, after the plunger 27has been raised to urge the work into correct position relatively to the opening 26 formed by the matrix plates 24, engages a step 188 forcing the sole through the opening 26.

of-a lever 190 which is pivoted on the shaft 162 and has at its rear end a slot 192 shaped to receive a block 194 mounted upon an arm 196 which is secured to the shaft 176. Upon the shaft 176 is, another mm 198 to which is pivotally secured a link 200 for trippingthe clutch.

The degree of adjustment of the matrix plates -'I olude the shoulders 21,the operator places the heel end of the sole upon the top face'of theplunger 2'7 flesh side up and forces the rear end of the sole against the bifurcated portion 142 of the gage 28, to centralize the sole and at the same time pushes the gage rearwardly against the stop 146 to position the sole lengthwise. The treadle rod 138 is then lowered to raise the plunger 27 for As. the plunger 27 is raised the clamping members 98,

3 are forced against and cooperate with the beveled faces 42 of the matrix plates 24 to clamp the sole as the bulger continues its upward movement to I push the sole through the opening 26 and above the upper faces 30 of the matrix plates. When the'face 60 of the bulger 54 arrives at a. position very slightly below the: level of the faces 30 of the plates 24, further upward movement of the bulger is prevented by contact of the lever. 88 with the stop 110. Upon further upward movement off the 'treadle rod 138, the pin 186 engages the step 188 of the lever 190 to trip through the abovedescribed, mechanism the one-revolution clutch (not shown) which actuates the knife 32 to cause the same to move over the plates 24 to trim from the sole portions of the same which are located below the faces 30 of the matrix plates 24. In the meanwhile the bifurcated link 160 is moved through the above-described mechanism rearwardly of the machine to a position behind the pawls 154 of the gage 28. After the sole has been trimmed and the plunger 27 has been lowered to a position below the gage 28, the link 160 is released and strikes the pawls 154 to move the gage Y 28 forwardly of the machine to .push from the machine a chip .which. has been removedfromthe solesandwhich'is located .on. the plunger 27.
