Application filed March 25, 1912. Serial No, 686,042.

.1 b all whom it may concern:

Be it known that I, RALPH C. SIMMONS, a citizen of theUnited States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Shoemaking-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to shoe making machines and is herein shown and described, by way of exemplification merely, as embodied in a machine for breasting heels. It is to be understood, however, that various features of the invention are susceptible of embodiment in other machines.

It is usual, in finishing the heels of certain styles of shoes, to breast the heels of a pair with the edges of the heel breasts equally and oppositely inclined to the longitudinal median lines of the heels. Difliculty has been experienced, however, in accurately positioning and holding the heels for this operation, and it is an object of the present invention to provide means for enabling a shoe to be positioned accurately and held positively which engages and moves with the forepart of a shoe,'and also to provide new and improved means for locating and holding the heel portion of a shoe against movement in the plane of a tread face.

An important feature of the invention consists in a forepart engaging and positioning device having inclined forepart engaging faces acting automatically to position the shoe relatively to the knife irrespectively of the size of the shoe and is herein shown as arranged to move with the shoe equal and opposite distances from a normal position in which the longitudinal median line of the shoe is perpendicular to the plane of the knife to position the shoe relatively to the knife for breasting heels rights and lefts. In the form shown, the toe portion, or the forepart, of the shoe is engaged by a V-shaped notch in a locating plate which acts to center the shoe over the apex of the notch irrespectivelyof width Or size of the shoe. In order to provide for the right andleft positioning movements of the the locating plate is toe portion of a shoe,

sliding movement in arranged for limited a horizontal plane, means being provided for adjustably limiting this movement.

Another feature of the invention consists in a locating plate mounted for movement vertically and normally held in an elevated position by resilient means. This construction enables the shoe to be located laterally while it is still free to be moved in a vertical plane, so that the tread face of the'heel may be brought into parallelism with the tread or presser plate when it is inclined to the horizontal in order to give the breast face an oblique inclination to the tread face of the heel.

It is found in practice that there is considerable variation in the height, from cone to heel seat face, of commercial lasts which are normally of the same size and hence it is found that for a given vertical adjustment of the last pin of the jack there will be considerable variation in the distance be-- tween the presser plate and the tread face of the heel, and hence a back stop on the presser plate which will engage the rear of the top lift of one heel may fail to engage, because of variation in the height of the last, another heel of what is really a shoe of the same size and style.

Accordingly another feature of the invention consists in a back stop which automatically accommodates itself to height variations of lasts and engages the shoe at the rear and positions it relatively to the knife irrespectively of any ordinary height variations. This stop comprises a member pivotally connected beneath the presser plate at some distance to the rear of the heel. The forward end has a limited free movement vertirally and is held in its lowermost position by gravity. The forward portion of the stop is upwardly inclined and is arranged to be engaged by the upper edge of a rearwardly moving heel and moved upwardly about its pivot until the rear face of the heel comes in contact with a pro ection carried upon the inclined face of the stop member, whereupon the rearward movement ofthe heel is terminated and the longitudinal position of the heel relatively to the knife determined. As the presser plate is now depressed to clamp the heel, the stop member, by reason of its pivotal connection with the presser plate, maintains its operative position against the heel.

Patented Jan. 25, 1916.-

' locking the arms against the prises novcl mechanism for holding the heel portion of the shoe from movement in the plane of the tread face of the heel. This mechanism comprises'means resiliently pressed inwardly to engage the heel upon opposite sides and means whereby the heel engaging means are automatically locked in place as the shoe is positioned relativelyto the knife and act to hold the heel firmly in place until the breasting operation is completed, whereupon as the shoeis withdrawn from beneath the knife the locking means is released and the side engaging means are free to position themselves against a new heel, irrespectively of its widtl As herein'shown the side engaging means comprises members which are carried upon arms connected together for equal and opposite movement, and a spring is provided for holding them in an initial position such that the distance between them is less than the width of the kind of heel being breasted. Means is provided also for varying the initial distance between the members for different sizes of heels. Means is also provided for positively when they have assumed their position against the sides of the heel,v and as herein shown this means is operated by pressure against the stop member which engages the rear face of the heel. As the heel is pushed into place the clamping members are separated and the heel permitted to engage the back and lateral position of the heel is determined. 'By a slight further pressure back stop the locking mechanism is operated which positively holds the clamping members against the sides of the heel until after the breasting operation, when a slight movement of the shoe longitudinally forward releases the locking mechanism which remains inoperative until another shoe is introduced.

Another feature of the invention consists in means for positioning and clamping the shoe which is mounted independently of the presser plate which engages the tread face of the heel for movement in the plane of the tread face about an axis which. lies at the mid portion of the front edge of the presser plate and substantially perpendicular thereto. This construction permits the shoe to be swung after it is clamped about the said axis which approximately coincides with that of the heel pin of the last so as to locate the heel for breasting rights and lofts. Means is provided for limiting the movement of the shoe positioning and clamping means equally in opposite directions or the amount of lateral swing of the shoe may be determined by movements of the toe rest, as has been described.

These andotherfeatures of the invention, including novel means for taking up wear stop and the rearward in the knife actuating andcontrolling 'mechanism and for preventing slipping of the claims.

In the drawings,-Figure l is a perspective view of portions of a-breasting machine provided with an illustrative embodiment of certain features of my invention including the novel toe rest and forepart lcating device; Fig. 2 is a plan View of the heel clamping and positioning mechanism detached from the machine; Fig. 3 is a longitudinal section on the line 38 of Fig. 2; Fig. elis a perspective view of the presser tread plate and adjacent parts; Fig. 5 is a side view of a detail; Fig. 6 is a sectional detail. 7

The machine frameis designated, Fig. 1, by the numeral 2 and is provided with grooves or ways t in which the knife carrying slide 6 and the knife actuating slide 8 are mounted for vertical reciprocation. The latter is power actuated through a suitable one-revolution clutch which is tripped by the last part of the downward stroke of the treadle of the machine. A slide 10 carrying a heel support comprising a tread or presser plate 12 is depressedupon the heel by the first part'of said treadle stroke. The knife carrying slide 6 has an arm 1% and

cheek pieces

16, 18 which form abutment-s for the ends of the'front clamping plate 'for the knife 22. The knife is clamped in its holder by screws 2l and is adjusted longitudinally by the abutment screws 26.

The knife carrier slide 6 is detachably connected with its actuating slide through a strut l5, Fig. 6, pivoted to carrier 6 at A2 and engaging under a roll 4:7 on the slide 8. The strut is engaged by the upper arm 44 of a bell crank which is also pivoted at A2 to the knife carrier and the horizontal arm of which carries adjustably a shank gage or stop which upon meeting the shank of the shoe. forces strut 45 from under roll 47 and allows the roll and theknife actuating slide 8 to proceed to the completion of their, down stroke without further actuating the knife. On its upward stroke the actu ating slide picks up the knife carrier to lift the knife by meeting a cap plate 30, Fig. 1, that is fastened to the top ofthe knife carrier and overliesthe actuating slide. A spring 4:1, Fig. 6, is provided to press the strut 4-5 under the roll 47 when the slide has picked up the carrier. Lost motion or wear sometimes makes adjustment necessary in order that the strut and roll may properly reengage and this is provided by forming on the lower face of the cap plate 30 a rib 32 and fastening the plateto the knife carrier by screws'34 located on opposite sides 2' of the rib wherebythe plate can be tipped about therib to adjust up or down the edgeportion which is engaged-by the actuatingslide. A vertical adjusting screw stop 46 depending from arm d0 of the bell crank and engaging the knife carrier 6 variably determines the extent to which the strut 15 shall extend under the roll 41:7 and thus variably, determines the furthenmovement of the knife which shallbccur after the shank gage 50 meets the, work and before the knife is freed from its actuator. I a a The shoe is supported upon a jack comprising the usual rigid support for the heel end of the last comprising a last pin 60 on a post 61 and a toe rest comprising an. arm 62 which branches from the post and carries the novel toe rest and toe locating device embodying an important feature of my invention. This comprisesa vertically movable slide 64 having dove-tailed guides con necting it with a member 66 and normally held elevated by a spring 68. The member 66 is mounted for lateral sliding movement upon a bar 70 which is fixed to a standard 72, the standard being mounted for vertical adjustment in the block 76 by the worm 74c. The block 76 is adjustably fastened. to a plate 82 by the thumb screw 78 and slot 80 in the plate 82. Adjustment of the toe rest as a whole upon the arm 62 is providedby another slot in the plate 82 and the set screw 84 passing through that slot and threaded into the arm 62. To limit the lateral sliding movement of the toe rest upon the bar 70, stop screws 65, 67 are provided which are threaded through the member 66 and are arranged to contact with the standard 72'and limit the movement of the member 66 on the bar 70 and hence the movement of the toe resting and locating plate 61. Spline and groove connections are provided between the bar 70 and the member 66 and between the standard 72 and the block 76 to prevent relative rotary movement of the parts. Then there is no shoe on the jack the plate 6% will be elevated by the spring 68 and when the shoe is placed on the heel pin 60 with the toe resting upon the plate 6 1 it will be depressed more or less. The shoe may be swung either to right or left until one or the other of the stop screws 65, 67 strikes the post 72. The right or left swing of the shoe is thus determined and hence the inclination of the plane of the knife or heel breast to the longitudinal median line of the heel. The V-shaped notch in the plate 64 centers the shoe over the member 66 irrespectively of its width or size and the amount of lateral swinging movement of the shoe may be changed or adjusted by the

screws

65, 67. When the heel is clamped by the tread plate the forepart will be raised or, lowered automatically to bring the treadface of the heel into parallelism, with the acting face of the plate and determine the vertical inclination on which the heel will be breasted The spring 68 allows theforepart rest to yield to or to follow up themovement of the forepart of the shoe while continuing to control the lateral position of the forepart. '8

The. tread plate 12 is adjustably secured to a casting 90 by screws 92; The casting 9O is pivoted at 9% to the slide 10 and the usual means, comprising a screw 93 acting against an upward extension 95 of the cast ing 90, is provided for adjusting the tread plate angular-1y about the pivot 9% for varying the inclination of the breast to the tread face of the heel. The extension 95 and screw 93 are maintained in engagement by the weight of the parts, as the weight of the partsto the rear of the pivot pin 9% is inexcess of that in front. A segmental T slot 96 is formed in the casting 90 which receives a T guide 98 on a plate 100. The

parts

90 and 100 have their relative movement properly limited for a purpose to be described by pins 102 which engage any one of a series of holes in the part 100 and abut against the part 90. On its under side the plate 100 is provided with guides 106, Fig. 3, inwhich a plate 108 is mounted for adjustment longitudinally of the shoe. To the plate 108 is pivoted at 110 a member 112 having an upwardly projecting forward portion 111 provided with a vertical stop face113, with which the rear edge of the shoe heel may contact. The inclined portion 111 extends upwardly through a slot in the tread plate 12, Fig. 1. When there is no shoe in the machine the member 112 drops down as far as the projection 114: thereon Fig. 3, will permit, the end of the portion 111 being then only slightly above the lower face of the tread plate 12. Q As the shoe is swung in under the tread plate it will engage the inclined face of portion 111, whether theparticular last brings the shoe up close to the plate 12 or not, and as the shoe is pushed backwardly it will act on the inclinedportion 111 to raise the member 112 and will finally contact with the stop 113, its rearward movement being thus arrested. Foradjusting the plate 108 and hence the member 112 and stop 113 forwardly and backwardly, in accordance with the size of the heel and the amount to be removed therefrom by the breasting opera tion, one edge of the plate 108 is provided with teeth, Fig. 2, which engage a worm 116 which is adapted to be turned by hand for adjusting the plate and consequently the stop 11S backwardly and forwardly. The tread or presser plate 12 is slightly hollowed out or concave on its under face so that more pressure is applied to the heel about its periphery than upon its central portion, whereby lateral and swinging movements of the shoe relatively to the plate are prevented. As rearward 'movements of the shoe are controlled by the back stop 113, the concavity of the presser plate is preferably transverse or cylindrical with the axis of the cylindrical concavity extending longitudinally of the shoe.

'Forpositioning and holding the heel laterally,

arms

130, 132 are'provided which are pivoted at 131, 133, respectively to the plate 100 and are curved away from each other so as to contact at their ends only with the sides of the heel, the ends being formed with cylindrical enlargements 129 Which permit lateral swinging of the shoe on the toe rest but hold the heel against lat eral bodily movement. The

arms

130, 132

have inwardly extending portions 134 formed with meshing teeth so that their shoe engaging ends will move equally and oppositely and the arm 130 has a rearward extension 136 carrying a toothed segment which meshes with a toothed portion of a cross bar 138. The bar 138 is mounted for sliding movement in depending portions of the plate 100 below the plate 108 and is held in place by a retaining plate 140, Fig. 1. The cross bar 138 is normally forced to the right by a helical expansion spring 1 12 which is positioned on

studs

139 and 101 secured to the bar 138 and the plate 100, respectively. The spring 142 obviously holds the shoe engaging ends of the

arms

130, 132 toward each other or closed upon,

the shoe and the normal separation of the arms is controlled by a stop pin 14:1 adapted to engage any one of a series of holes 143 in the left-hand end of the bar 138 and arranged to contact with the part 100. As the shoe is swung in beneath the plate the

arms

130, 132 center the heel laterally and are separated by introduction of the heel between them and then'therear edge of the :heel engages the inclined portion 111 of the member 112 and is arrested by contact with the stop 113.

It is desirable to have the arms-130, 132 locked against separation when the shoe is fully positioned and this is effected by a slight rearward movement of the stop 113 by pressure of the shoe against it. The worm 116 is'fixed to a stem 150 which slides in a lug 152 on the part 100 and passes through a hole in that part, Fig. 5, into engagement with a catch lever 154pivoted at 156 between its ends and having its lower end formed to interlock with notches 158 in the rear edge of the bar 138, Fig. 2. The catch lever is normally held out of engagement with the notches in the bar 138 by a spring 160, which, acting through the lever .154, the stem v150, the worm 116 and the ing the

arms

130, 132 in engagement with the shoe.

It will be observed that the whole heel positioning and clamping mechanism except the tread plate 12 is mounted on the plate 100 which is formed with the T-shaped segmental 'rib 98 mounted for sliding movement in the part 90 as described and that afterthe shoe is positioned by the back stop and its heel clamped by the side arms it may be swung with these clamping means and the plate 100 aboutthe center of curvature of the guide rib 98 (which lies approximately at the edge of the tread plate) to the right or left to an extent limited by the position of the pins 102 in the holes 103 in the opposite ends of the rib 98. Means is thus provided for positioning the heels of right and left shoes, which positioning means may be used in conjunction with the toe resting and locating device or independently thereof. 7

In the operation of the machine the jack is swung forward in the usual manner and the shoe, with the last in it, placed upon the pin 60, or, alternatively, for breasting off the last, a heel plate might replace the last pin 60, with the toe in the notch of the plate 61 which centers the forepart of the shoe and permits movement thereof vertically to accommodate it to the inclination of the plate 12. The jack is then adjusted vertically by'the usual hand wheel, Fig. l, to the approximate height appropriate for the size of the shoe that is to be breasted. The

shoe is next swung back with the jack beneath the plate 12 and between the side engaging ends 129 of the

arms

130, 132 which center the heel and then separate against the tension of the spring 142 and move the bar 138 outwardly. The rear edge of the shoe heel engages the inclined portion 111 of the back stop 112 and raises it until the shoe contacts with the stop 113 against which it is pushed with suflicient pressure to overcome the tension of thespring 160 and force the locking catch 15st into engagement with the notches 158 on the bar 138 to lock it and the said engaging members 129 against movement. The tread plate is then partiallydepressed by the starting treadle and the shoe swung to the right or left, according to whether it is a right or left shoe, until one or the other of the screws 65, 67' engages the standard 72 or one or'the other of the pins 102 engages the part 90, if'the pins are employed. The treadle is then further depressed to apply more pressure to the tread face of the heel to clamp it firmly and to trip the clutch whereupon the actuator the knife,

slide 8 will descend carrying with it the knife slide 6 and knife 22 until the latter is about to reach the shank when the stop 50 will come in contact with the shank and tip the lever 40 about the pivot 42 until the upper end of the arm pushes the strut as from beneath the 101147011 the actuator slide 8. The knife is thus disconnected from its actuating mechanism and ceases to cut by the time it has passed through the heel. The actuator then completes'its stroke and upon its return comes in contactiwith the plate 30 and lifts the knife to its initial position, allowing the arm 44: to resume its normal position and the strut e5 to become reseated under the roll for the succeeding operation.
