To all whom it may concern/.1"

Be it known that I, J W. Cosenovn, a citizen of the United- States, residing at Mediord, in the county of Middlesex and. State of Massachusetts, have invented certain new and useful Improvements in Ma;- chines for Shaping Lipped Soles;- and Ido hereby declare the following to. be a full, clear, and exact description of the invention, such. as will enable others skilled in. the art to which it appertains to make and, use the same- The present invention relates to machines for operating upon'lipped soles during their process of manufacture and more partic ularly to machines for shaping and setting. the lips of insoles- The object of the invention is to reorganize machines of the above named general character and to provide certain improvements in their construction and mode of operation for the purpose of increasing their eliiciency,v rendering unneceseertain. adjustments of the operating parts, and. enabling the sole tov be properly located for the operation to. be performed: thereon without the employment of. special. positioning devices- To the accomplishment of this object and such others as-niay hereinafter appear, the invention resides in the features of construc'- tion. and combinations of parts hereina'tter described and particularly pointed out in the appended claims, the advantages of which will. be apparent to those skilled in the art.

The invention will be best understood. by reference to the accompanying drawings, in which the invention is illiistrated in its preferred form as embodied in a machine for shapii'ig'and" setting the-lip at the toe of an insole.

In. the drawings, Figure 1 is a view, in frontelevation, oi the machine; Fig. 2 is a view, in side elevation thereof, looking. from the left in: Fig. 1, Fig. 3 is a plan view of the machine; Figs. i and 5 are detail views in. plan andtront" elevation, respectively, Oii' the work table; 6 is a section. on the line 6 6ot Fig. 3; Fig. 7 is a detail plan view, on. an enlarged scale,.ol the inner form or mold; Fig. 8 is a view, in side elevation, of the form or mold shown in Fig. 7, Fig,

9 is a section. on the line 9-9 of Fig; 10 is a. detail. plan view, on an. enlarged scale, of the outer torm or mold and Fig- 11 is a view, inside elevation, of the form shown in Fig..10.

As shown in:- Figs- 1-, 2 and 6, the working parts o t the machine are mounted on: a hollow head 12: and are supported at. a convenient height for the operator by apedestal 14, to which the head is. secured... Thehead 12. is of irregular shape, having two o prpositely disposed upright sides 16. and a projecting. front portion 18. The. sides 16 oil the head are provided with bearings. 20 for a. horizontal main shaftQZ, and are extended upwardly above the bearings- 20 to support a fixed rod 24,. upon which certain. actuating lovers. are pivoted, as will be hereinafter. described. Secured tothe upper time of the portion. 18. of the head is. a. work. table. 256,. by means of which the-insolesare supported while they are being operated upon...

The lip shaping: and? setting operation is. performed by two cooperating 'inol ds orv forms 30 and 32 (Fig. 2 and G) which are shaped to. engage the outer and inner sides, respectively, or the lipat the toe of the insole. For convenience, the form. 30 will hereinafter be referredto as the outer form or mold, and the form. 32v as the inner form or mold. To enable the forms to perform their shaping, and setting functions, the outer form. 30 is constructed with a V shaped notch Set, as illustrated. in Fig. 10,. and the inner form 32 is provided with a correspondingly shaped. projection 36, as shown in Fig 7, which is adapted to cooperate with the walls of the notch 34 to mold' or shape the lip. Molds or forms ofdi'fferent shapes will. be used r01- insoles having differently shaped: toes, the forms illustrated in. Figs. 7 and 10 bein adapted for use" upon insoles having comparatively narrow or peaked toes. Normally the outer form 30 is. posi tioned, as shown in Figs. 2' and 6, at a snilicient elevation above the work table 26 to permit the insertion, between the form and the work table,.of thefeather atthe toe of the insole, while at the same time the form is near enough. to the worli table to enable the opposite side walls of the notch 3 1 to be engaged by the lip of the insole as the latter is pushed rearwardly across the work table by the operator. The outer form thus serves as a gage to position the insole longitudinally upon the work table for the performance of the lip shaping operation, making it unnecessary to provide sol'e gages or other positioning devices. The inner form 32 is normally positioned somewhat higher above the work table than the outer form to facilitate the presentation of the insole to the latter. After the insole has been positioned on the work table by the engagement of the lip with the outer form, both the inner and outer forms are depressed until they are brought into pressing engagement with the insole, the inner form engaging the face of the insole between the converging toe portions of the lip and the outer form engaging the feather of the insole, adjacent the point of the toe, so that the toe portion of the insole is flattened against the work table.

The mechanism for imparting to the inner form its insole pressing movements comprises a vertically movable slide 40 (Figs 2 and 6) to the lower end of which the inner form is secured, and cam actuated devices connected with the upper end of the slide. In order that the inner form may be readily removed from the slide 40, so that it may be replaced by another form having a different contour, the form is conveniently provided with a transverse dove-tailed tongue 42 which is received in a correspondingly shaped groove 44 in the slide, and is secured therein by means of a clamping screw 46, the lower end of the slide being slotted longitudinally, as shown at 48, to provide sutficient yielding movement of the walls of the groove. The slide 40 is freely movable vertically in a guideway 50, centrally formed in a slide-carrier 52, and is provided, on each side of its upper end, with pivoted blocks 54 (see Figs. 1 and 2) that are mounted in the slotted bifurcated end 56 of a lever 58 which is pivoted on the fixed rod 24. The lever 58 is, in turn, actuated by a bellcrank lever 60 which is pivoted on the rod 24 alongside of the lever 58. One end of the bell-crank lever 60 carries a cam roll 62 which is received in a suitable cam groove in a cam disk 64 that is secured to the main shaft 22. The other end of the bellcrank lever 60 is yieldingly connected with the lever 58 by mean comprising a rod 66 (Figs. 1, 2 and 3) which extends through an car 68, projecting laterally from the lever 58, and is pivotally connected, by means of a stud 70, with the bifurcated end of the bellcrank lever 60, ashoulder 72 being formed adjacent the pivoted end of the rod 66 to bear against the under face of the ear 68. A spring 74 surrounding the rod 66, engages at one end the ear 68 and at the opposite end an adjusting nut 76, normally holding the ear 68 in engagement with the shoulder 72.

insoles of different thicknesses, provision is made for adjusting the slide 40, and the form carried thereby, toward and from the work table. This is accomplished by an cecentric mounting of the pivotal supports for the blocks 54 carried on the upper end of the slide 40. As shown in Figs. 1 and 6, a cireular aperture is formed in the upper end of the slide 40, in which is mounted a cylindrical stud 80, the upper end of the slide being split as indicated at 82 and provided with a clamping screw 84 so that the stud may be clamped in any desired radial position. Projecting from the ends of the stud 80 are pins 85, the axes of which are coincident, but eccentric relatively to the axis of'the stud. These eccentric pins 85 extend through and constitute the pivotal supports for the blocks 54. The pins 85 are severally provided with screw-threaded axial holes, and in each of these holes is secured a screw 86, the head of each screw overlapping the outer face of a block 54 and serving to hold it within the slotted bifurcated end of the lever 58. By loosening the clamping screw 84 and turning the stud 80, the slide 40 and the form carried thereby may be brought in to the proper vertical adjustment for the thickness of the insoles which are to be operated upon.

The mechanism for depressing the outer form against the feather at the toe of the insole comprises a vertically movable cylindrical slide upon which the form is mounted and which is operatively connected with the lever 58 by means of which the inner form is depressed. As shown, the outer form is removably secured to the slide 90 by means of a headed bolt 92, which extends through a horizontal slot 94 (Fig. 11) in a lug 96 rising from the form, and is threaded into the slide, the bolt binding the rear of the form against a flat face 98 formed on the front of the slide. The slot 94 is open at one end so that the form may be removed from the slide by merely loosening the bolt 92. To maintain the form with its under face parallel to the supporting table 26, a transverse rib 100, which extends across the front of the face 98 on the slide 90, is received in a groove 102 (Fig. 11) that is formed in the rear side of the lug 96. The slide 90 is freely movable vertically in a guideway 104 (see also Figs. 4 and which is formed integral with the work table 26 and is slotted, as shown at 106, to permit lUU the guideway 104 by the lug 96 on the outer form which projects beyond the sides of the slide and engages bearing faces 108 on the guideway at opposite sides of' the slot 106..

The engagement of the lug'96 with the bearing faces 108 thus determines the horizontal angular position of the outer form. "he slide 90 is yieldingly actuated so thatthe outer form will properly engage feathers of varying thicknesses without the necessity of adjustment. To this end the upper portion of the slide 90 is reduced in diameter to form a post 110 which extends loosely through an opening 112 in an ear 114,, the latter proj ecting, laterally from the lever 58 on. the opposite side from the ear 68. A spring 116 surrounding the post 110 engages at one end a washer seated against a shoulder 118 formed at thejunction of the post 110 with the main portion of the slide 90. At its opposite end the spring 116 engages a collar 120 having a convex bearing surface to engage against a concaved wall on the under side of the ear 114. The upper end of the post 110 is screw threaded to receive a nut 122 which is also provided with a convex bearing surface for engaging a concaved wall on the upper side of the ear 11 i and is held in place on the post by a lock nut 12d. By means of this construction of the slide 90, the form carried thereby is yieldingly depressed by the lever 58 as the latter is actuated to depress the inner form. As soon as the outer form has been brought into pressing engagement with the feather, which occurs before the inner form has been moved into contact with the insole, the spring 116 yields while the lever 58 continues to move the inner form downwardly.

After the outer and inner forms have been depressed into engagement with the insole, the inner form is moved horizontally toward the outer form to mold the lip into the required shape. The inner form is given its horizontal or lip-engaging movement by means of the slide-carrier 5.2, which is clovetailed to move horizontally in guideways 128 (Fig. 1) formed in the transverse portion of a substantially U-shaped bracket 130. As shown in Figs. 2. and (3, the bracket 130 proj ects forwardly from the upward extensions of the sides 10 of the head 12 and extends horizontally above the work table 26, the oppositely disposed arms of the bracket being secured, at their free ends, to said upwart extensions by means of bolts 182. This construction leaves free space at both sides of the forms for the manipulation of the sole. The means for actuating, the slide-carrier 52 comprises a cam lever 134-, the lower end of which is pivotally mounted upon a fixed stud 136 projecting inwardly from one of the sides 16. At its upper end the cam lever 13% is provided with a rearwardlyprojecting arm 1'38 carrying a cam roll 140 which is received in a suitable roove in the cam disk 64'. The cam lever 13% is operatively connected with the slide-carrier 52 by a horizontal rod. 1 4:2, 6) one end of which is pivotally connected with the upper end of the cam lever. wardly through acentral recess in the horizontally movable slide-carrier 52,. the vertically'inovalfie slides 90 and being slotted; as indicated at 14 1- and l i-6, resJect-ively, to permit'its passage therethrough and to permit vertical movement of said. slides without interfering with the rod. in the slide-carrier 52, through which the rod 142 extends, is counter bored, as shown at 148, to receive a coiinspring 150. "he spring 150 surrounds the rod 1 i2;,on.e end of the spring bearing against the base of. the counter bored recess, at the rearof the slidecarrier, and the opposite end of the spring engaging a nut 152, which is threaded onto the forward end of the rod 1&2, and is secured in place by means of a lock-nut. 154; This construc ion provides a yielding connection between the slide-carrier 52" and the cam-lever 134 so that after the inner form has reached the limit of its horizontalmovement against the lip of the insole, further actuation of the cam lever will cause con pression of' the spring 150 without damage to the parts. By reason of this yielding connection, no adjustment of'the inner form need be made for insoles having lips of varying thicknesses. By turning the nut to vary the compression of. the spring 150', the molding pressure exerted by the inner form may be altered, a heavier or lighter pressure being produced as may be desired. In order to provide for positive movement of. the inner form away from the lip of the insole, a shoulder 156, formed 011 the rod 142, engages the rear of the slide-carrier 52,. after the compression of the spring 150 has been relieved and returns the inner form to its normal horizontal position. i

In order to insure that the inner form will engage .the channel at the base of the lip of Economy and like insoles, the under side of the inner form is somewhat undercut or bevelled, as indicated at 160, in Figs. 6 to: 9. 1 By thus bevelling the under side of the inner form, the marginal portion of the under side of the form is permitted to seat itself in any groove or channel which may be formed in cutting an inner channel flap in the process of forming a. compound lip. 7

After the lip has been molded into the required shape between the inner and outer forms, additional pressure is applied to the inner form, through the action of its actuating cam in the disk 64, to force the marginal portion of'the bevelled lower side ofthe The rod 142' extends for- V The central recess &

form firmly against the channelled portion of the insole. Inasmuch as the inner form at this time is held yieldingly against the inner side of the lip, this additional pressure upon the form causes said marginal portion thereof to apply heavy downward pressure exactly at the base of the lip. This operation assists in setting the lip so that it will retain its molded contour.

It is obvious that in cases where it is desirable to have the lip of the finished insole inclined either inwardly or outwardly from a plane normal to the insole, the lip-engaging faces of the cooperating forms may be inclined sufficiently from a vertical plane to produce the desired result. In the drawings, the inner and outer forms have been constructed, as best shown in Figs. 8 and 11, with their lip engaging faces so pitched as to mold the lip in a somewhat inwardly inclined position. lVith the lip thus inwardly inclined, it is easier for the operator to last the toe and to maintain the lip in proper relation to the channel guide during the operation of sewing the upper to the insole.

In order to return the inner and outer forms to their normal elevations above the work table to permit the removal of the insole, the bell-crank lever 60 is rocked by its cam in a direction to relieve the compression of the spring 74. When the shoulder 72 on the rod 66 engages the car 68 on the lever 58 the latter, together with the slide 40 and the inner form 32, will be positively raised. As the lever 58 moves upwardly, the compression of the spring 116 is also relieved and finally, when the ear 114 engages the nut 122 on the post 110, the slide and the outer form which is carried thereby, are positively raised to their normal positions.

The main shaft 22 of the machine is actuated by means of a constantly rotating driving pulley 162 which is mounted loosely on said shaft and arranged to be connected thereto by clutch mechanism which is adapted to be thrown into operation by the operator after the insole has been positioned upon the work table and to be automatically thrown out of operation after the shaft has completed a single revolution. A pin-type clutch of well known construction is employed. As indicated in Figs. 1, 3 and 6, the clutch comprises a bushing 164, fast on the main shaft, the bushing projecting into a recess in the hub of the pulley, and a clutch pin 166 which is mounted for horizontal sliding movement through the bushing to bring its inner end into or out of the path of one or the other of two driving lugs 168 carried by the pulley. A spring 170, seated within a recess in the bushing 164, acts upon a projection 172 on the clutch pin and tends to force the clutch pin into position to be engaged by one of the driving lugs 168. To the outer end of the clutch pin 166 is secured a head 174 which is provided with an inclined face 17 6, as best shown in Fig. 3. The face 176 is adapted to cooperate with a clutch controlling member in a well known manner. In the construction shown, the clutch controlling member comprises an arm 178 which is movable toward and from the main shaft. To this end the arm 178 is fast upon a rockshaft 180 that is journaled in a bearing 182 in its normal position, as shown in Fig. 6,

the clutch pin 176 will be held retracted so that it cannot be engaged by the driving lugs on the pulley 162. The clutch is then inoperative and the pulley will rotate freely while a braking device holds the main shaft stationary.

The braking device comprises a brake disk 190, which is fast on the main shaft, and a brake shoe 192, carried by the rock-shaft 180 and arranged to engage the periphery of the brake disk. In order that the brake shoe 192 may be actuated to disengage the brake disk when the clutch controlling arm 178 is moved away from the main shaft, and to grip the brake disk when said arm is moved in the opposite direction, the brake shoe is pivotally mounted on an eccentric sleeve 194 which is secured to the rock-shaft 180. The eccentric sleeve 194 is provided with an extension 196 (Fig. 3) concentric with the axis of the rock-shaft 180, which extends through the bearing 182. The outer end of the concentric extension 196 is slot ted as indicated at 197 and provided with a clamping screw 198 by which it is clamped to the shaft. By loosening the screw 198 and shifting the eccentric sleeve radially on the shaft, the brake shoe may be adjusted relatively to the brake disk to compensate for wear.

When the clutch controlling arm 178 is swung in a direction to withdraw the stud 184 from the inclined face on the head 174, the clutch pin will be projected into position to be engaged by one of the lugs 168 on the driving pulley, thereby connecting the pulley with the main shaft. As the clutch controlling arm is thus moved, the resulting oscillation of the rock-shaft 180 and the eccentric 194 disengages the brake shoe 192 from the brake disk 190 to permit the rotation of the main shaft.

The clutch controllng arm 17 8 is actuated to render the clutch operative or inoperative by mechanism controlled by a foot treazdle (not shown). This mechanism comprises an arm 200, (Fig. 6) which is formed integral with the clutch controlling'arm 178 and-carriesa latch 202 pivota'lly connectechby means of a stud 204, with the bifurcated end of said arm. The latch projects between the ends of a forked arm 208 which is pivotally mounted on the fined stud 136, and the hooked lower end of the latch is adapted to be engaged by a pin 210 carried by the arm 208. The forward end of "the arm 208 is pivotally connected to the upper end of a rod 212, the lower end of which is connected with the foot treadle. The latch 202 is normally held with its hooked end in engagement with the pin 210 by means of a grasshopper spring 21s which is coiled about the pivot stud 204, one end of the spring bearing against a pin 21-6 on the arm 200 and the other end of the spring bearing against a stud 218 on the latch. When the treadle is depressed, the rock-shaft 180 :and the eccentric sleeve 194' are rotated in a direction to disengage the brake shoe from the brake disk, leaving the main shaft free to rotate, and the clutch operating arm is swung outwardly through movement of the latch 202, to render the clutch operative to connect the main shaft with the driving pulley. V

In order that the clutch operating mechanism may automatically return -to its normal position to disconnect the clutch after a single revolution of the main shaft, irrespective of whether or not the operator releases the treadle, provision is made for disengaging the latch 202 from the pin 210 immediately after the start of a cycle of operations of the machine. This is accomplished by means of a cam lever 220 6) which is pivotally mounted at its lower end upon the head 12 and carries at its upper end a cam roll 222, which rides in the same cam groove in the cam disk 64 in which the cam roll 140 is received. The cam lever 220-is connected to withdraw the latch 202 from the pin 210 by means of a rod 22%, one end of which is pivoted to the cam lever, while the opposite end of the is slotted, as indicated at 226, to receive the stud 218 on the latch. WVhen the lever 1220 has disengaged the latch from the pin 210 the spring 186, acting through the :arm 1'88, swings the :clutch operating :arm inwardly until the stud 184 thereon engages the periphery of the head 174. Just before the main shaft has completed a single nevodantion the stud I84 is permitted to move inwardly into the path of the inclined :face 176 and continued rotation 0f the shaft causes said face to move across the stud 184, withdrawing the clutch pin 166 from the path of the lugs 168 on the driving pulley. The rotation :ofthe rock-shaft 1'80 caused by the final inward movement of the clutch operating arm causes the brake shoe 192 to ,grip the brake disk and arrest the rotation'of the main shaft. The machine thns automatically stops after it has completed a single revolution with the forms 30, 32 and the work table 26 in the relative positions shown in Figs. '2 and 6, as above explained. When the operator releases the treadle a tread le spring {-nots'hoavn) swings the arm 208 upwardly against a stop 228 on the head 12, causing the pin 210 to be again engaged 'by thejlatch 202 :and thus restoring the clutch operating mechanism to normal position preparatoryto initiating the next cycle of operations of the machine.

It is not deemed necessary to illustrate and describe the'particular form of theicam grooves employed on the c-am'di-sk 64; as :any person skilled in the art, loy the exercise of ordinary mechanical skill cou ld construct such cam grooves from the foregoing description of the construction, organization and mode of operation of the machine.

'VVhile it is preferred to employ the specific construction and arrangement of parts shown and described, it will he understood that this construction and arrangement is not essential except so far as specified in the claims and may be changed or anodi fi'ed without departing from the spirit and "true scope of the invention.

A machine for operating upon lipped soles having, in combination, a frame, a work table carried by the frame for supporting the sole, cooperating inner and outer forms for engaging opposite sides of the lip at the toe of the sole, means for moving the inner form toward the other form to shape the lip, and a bracket secured to said frame at the rear of the work table and projecting forwardly and centrally above the table for guiding said inner form during its shaping movement.

18. A machine for operating upon lipped soles having, in combination, a support for the sole, cooperating inner and outer forms movable toward and from said support and into engagement with opposite sides of the lip of the sole, power mechanism for actuating said forms, and automatic means for throwing said power mechanism out of operation and for. stopping the machine with one of the forms in a position to engage the lip of the sole as the sole is moved over said support.

19. A machine for operating upon lipped soles having, in combination, a horizontal support for the sole, cooperating inner and outer forms movable vertically toward and from said support and also into engagement with opposite sides of the lip of the sole, power mechanism including a one-revolution clutch for imparting said movements to the forms, and automatic means for throwing said power mechanism out of operation and for stopping the machine at the completion of a single cycle of operations with the inner form positioned vertically above and the outer form positioned vertically below the top of the lip of the sole so as to permit the insertion of the feather of the sole between the forms and the support with the lip of the sole engaging the outer form.

20. A. machine for operating upon lipped soles having, in combination, a support for the sole, cooperating forms for engaging the inner and outer sides of the lip at the toe of the sole to shape the lip to a predetermined contour, both of said forms being normally retracted from the support, a single lever and connections for bringing both forms into contact with the sole, and means for operating the lever.

21. A machine for operating upon lipped soles having, in combination, a support for the sole, cooperating forms at the inner and outer sides of the toe end of the lip for shaping the lip to a predetermined contour, both of said forms being normally retracted from the support and adapted to be depressed to press the sole against the support, and means constructed and arranged to depress the outer form to hold the sole and thereafter to depress the inner form.

22. A machine for operating upon lipped soles having, in combination, a support for the sole, cooperating forms at the inner and outer sides of the toe end of the lip for shaping the lip to a predetermined contour, both of said forms being normally retracted from the support and adapted to be 'depressed to press the sole against the support, means constructed and arranged to depress said forms to hold the sole against the support and thereafter to impart additional pressure to the inner form, and means for relatively actuating the forms to shape the lip before additional pressure is imparted to the inner form.
