SOLE-PRESSING MACHINE.

Specification of Letters Patent.

Patented Sept. 26,1911.

To all whom it may concern:

Be it known that I, EDWIN N. PREBLE, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Sole-Pressing Machines; and I do hereby declare the 01 lowing 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 sole press ing machines of that class which comprise cooperating sole pressing forms adapted to operate upon a sole before it is incorporated in a shoe.

Machines of the class above referred to have been provided with solo gaging and ipping devices associated with one of the orms to enable the sole to be placed in the desired position with relation-to the forms and to prevent the sole from being displaced during the action of the for: s thereon.

The ob'ects of the present invention are to 'provi e sole molding machines -of.the class above referred to with so e aging and gripping devices which are si 1. 'ie'r in construction and more durable than those which have heretofore been devised. and to arrange and actuate the sole aging and ripping devices in an improve? manner so t at they are more efiicient in operation and so that the forms can'be more readily removed from and inserted in the machine.

.W'ith the above objects in view, the present invention consists in the devices, combinations and arrangement of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in 40 the art from the following descri tion.

a In the drawings accompanying t is application the present invention is illustrated as applied to a sole moldin machine of that type in which the lower so e molding form,

inaddition to a reciprocating movementtoward'and from the upper form to'produecressure and clearance, also has a horizbntai transverse movement into and out of lalinement'with the upper form, from and toward a position of resentation, that is, a position onvenient y accemible by the operator for the removal and insertion of soles. It is to be understood, however, that certain features of the invention are not limited to use in this type of sole molding machine, nor is the invention, except as defined in the claims,'limited to any particular construction or arrangement of parts.

The several features of the present invention will be clearly understood from an inspection of the accompanying drawings in which-- Figure 1 is a longitudinal vertical sectional view of a portion of a well-known type of sole molding machine with sole gaging and gripping devices embodying the several features of the present invention in their preferred form applied thereto. Fig. 2 is a detail plan view, partly broken away, of one of the lower form carrying slides with a lower mold thereon together with sole gaging and gripping devices associated therewith. Fig. 3 is a longitudinal sectional view taken on the line 3-3, of Fig. 2.

Fig. 4 is a cross sectional view takenoin" the line 44, of Fig. 3. Fig. 5 is a detail view in side elevation of the spring rcssed bell crank lever and its supporting )racket by which the movable jaw of the gripping device is actuated. Fig. 6 is a detail tional view taken on the line 6--6, of Fig. 3, illustrating particularly the manner in which the heel gage is mounted and the con nection between the heel ga e and its adjusting mechanism. Fig. 7 1s a detail seetional view of a port on of the mechanism for actuating the heel go o and indicating its ositior. aken on the ine 7-7, of Fig. 3. *ig. 8 is an underneath plan view of a iortion of the mechanism illustrated in Fig. Fig.9 is a detail plan view of a modified form of heel gage adapted for usewi'th either completely rounded soles or with what. are known in the art as block soles, the heel ends of which present a straight instead of a rounded edge. Fig. 10 "is a detail plan viewsimilar to Fig. 9 but showing the arms of the heel gage in position to coiiperale with a blocksole and Fig. 11 is a. detail view in side elevation of the parts illustrated in Fig. 9. x v

The machine, a portion of which is illustrated in Fig. 1, is a double machine, being provided with two sets of cotipt-arating sole pressing forms, the upper forms being stationary and the lower forms being reciprorated simultaneously in opposite directions cured in tin usual manner upon a carrier 2 which is supoorted from the stationary cross head 3, so to be adjustable vertically, by means of an adjusting wedge 4. The lower form is indicated at 5 and is removably mounted upon a slide 6 which reciprocates in a horizontal guideway formed on a vertical reciprocating cross head I. lleaziproeating movements are imparted to thecross head 7 from a crank shaft 8 by means of a link 9 and toggle levers 10. Reciprocating movements are imparted to the slide 6 transversely to the reciprocating movements of the cross head 7 by means of a bell crank 11 which is mounted upon the cross head 7 and has one arm connected to the slide 6 by means of a link 12, the other arm of the bell crank being connected by a link 13 to an arm 14 integral with a. rock shaft or sleeve 15 journaled on the frame of the machine. An arm 16 extends rearwardly from the rock shaft 15 and is connected by a coiled spring 17 to the stationary cross head 3. During the rising and falling movements of the cross head 7 the bell crank 11 is rocked and imparts inward and outward movements to the slide 6. The inward movement of the slide 6 is limited by a cross piece 18 at the rear end of the guideway of thc-slide. The form carrying slide on the opposite side of the machine, corresponding to the slide (5, is actuated by a similar bell cranlv which is connected to another arm rigid with the rock shaft. 15, the arrangement of the bell cranks and slides being such, as will be apparent from an inspection of Fig.1, that.

the reciprocating movements of'the slides take place during'the lower half of the reciprocations of the cross head 7 and its corresponding cross head in each direction.

The parts so far described and the other parts not hereinafter specifically referred to are the same in construction and mode of operation as corresponding arts of a sole molding m h ne which has ieretofore been devised an in and of themselves formno part of the present invention. V i The solegaging' and gripping devices,

illustrated in the drawings as embodying the several features of the present invention, comprise a heel gage to determine the position of the sole with relation to the lower form, and a sole ripping device which engages opposite surfaces of the solo atthe heel end and holdsthe sole in position during the operation of the forms thereon. It is often desirable, and when certain kinds of soles are to be operated upon it is necessary, to use a sole molding machine without heel gaging and gripping devices. The heel gage and. gripping device illustrated in the drawings are accordingly removably mounted in the machine, and to enable the gage and gripping devices to be removed without disturbing the relative position of the gage, which is adjustable for soles of different sizes. and the gripping devices, the gage and gripping devices are mounted upon a single carrier. This carrier is indicated in the drawings at. 19, and to permit the lower form to be readily removed and a form of a ditl'erent size or style substituted therefor without disturbing the heel gage and gripping device, the carrier 19 is secured to the form carrying slide 6 independentl of the lower form. The carrier 19 exten s longitudinally ot the slide 6 and its rear end is received in a slot formed in a plate 20 bolt;- .(l to the rear end of he slide. The carrier is removably held in position on the slide by means of a pin 21, engaging a recess in the front end of the carrier, and by means of a hand operated clamping lever 22 mounted upon the plate 20 and provided. with an inclined cam surface 23 engaging a correspondingly inclined surface on the rear end of the. carrier. A movement of the lever 22 in one direction securely clamps the carrier 19 in position, while a movement of the lever in the opposite direction releases the carrier and permits it to be moved to the rear and raised from the form carrying slide.

it is desirable in sole molding machines to use a complete lower form in preference to a lower form having the heel portion cut away or omitted, since the heel portion of a complete form presents a support for the heel portion of the sole while being placed in position and also the heel portion of the form atl'ords a means by which the form can he more securely held upon the form carrying slide. The heel gaging and gripping devices illustrated in the drawings are accordingly constructed and arranged to cooperate with a complete lower form and to enable the gage and gripping devices to be placed in the desired position with relation to the. form, the form is provided at its heel end with a longitudinal slot. The forward end of the carrier .19 projects into this slot and snugly fits the slot so that the forward Will of the carrier serves as a means for se- Me since.

The carrier for the heel gage and gripping v device thus performs the function of one of the usual form retaining pins projecting from the form carrying slide. The other retaining pin is indicated at 24.

The sole gripping device illustrated in the drawings comprises a stationa.ryjaw,25,consisting of the head of a pin mounted in the forward end of the carrier 19, and a movable jaw 26 pivotally mounted between ears pro jecting upwardly from the rear end of the carrier. The movable jaw 26 is opened and closed during .the reciprt eating movements of the form carrying slide so that the sole is gripped before the lower form comes into alinement with the upper form and is released by the time the lower form reaches its position of presentation. To actuate the jaw 26 during the movements of the form carrying slide, an arm carryin r a roll 27' is provided, which roll is arrang to rest upon the upper surface of the jaw 26 and to travel along the jaw during the reciprocating movements of the slide. The arm carrying the roll 27 projeats laterally from the horizontal arm of a bell crank 28 pivotally mounted on a bracket 2) secured to the cross hea 1 7. A rod 30 is mounted at one end in a flange of the bracket 29 and at its other end extends through a hole in the lower end of the vertical arm of the hell crank.

A coiled spring 31 surrounds the rod 30 and is interposed between the vertical arm of the bell crank and a flange on the bracket 29 so that thespring acts to hold the roll 27 yieldingly in engagement with the gripping jaw 26. During the backward movement of the form carrying slide the roll 27 holds the gripping jaw yiel lingly pressed against the sole. During the outward movement of the k form carrying slide the roll 27 travels along the gripping jaw 26 and passes from one T sideof its pivot to the other so that the pressure of the spring 31. is no longer operative to keep the jaw closed. To open the jaw a stop in the form of a block 32 is mounted upon the rear end of the gripping jawin position to be engaged by the roll 27 as the form carrying slide reaches thelimit of its outward movement. To regulate the distance to which the jaw is raised in being "opened the block 32 is adjustably secured to the jaw. A hand lever 33 projecting rearwardly from the hub of the bell crank 28 5'5 serves as a convenient means for raising the l h v n roll 24 from engagement with the aw 26 when the carrier 1915 to be removed from the machine.

i The heel gage illustrated in the drawings, 10 consists of two arms 34 angular ly disposed with relation to each other, as best shown in q lg'kQ, and projecting from a block 35. The block 35is-carr1ed upon a block 36 which is unmounted to slide on a rod 37 forming a part of the carrier 19 so as to be capable of adjustment to adjustthe heel gage for soles of difierent sizes. To enable the heel gage to be adjusted vert cally to bring it into the desired position with relation to forms of different thickness, the block 35 is mounted upon a horizontal pivot 38 on the block 36 so as to be capable of swinging vertically. A spring pressed locking pin 39, mounted in the block 36 and arranged to engage a series of teeth 40 on a downward projection from the block 35. locks the block and heel gage in adjusted position.

In the machine illustrated in the drawings the sole molding forms are placed. in the ma; chine with their toe ends toward the front. The heel gage is thus remote from the operator and is not conveniently accessible for adjustment. To enable the ,heel gage to be adjusted readily by the operator without loss of time, mechanism is provided connected to the heel age and extending to a point at the front 0 the lower form. This mech anism includes a longitudinally movable rod or bar 41 which extends longitudinally beneath the form carrying slide 6 and projects upwardly through a slot at the rear of the slide into position to engage a projection from the block 36 upon which the heel gage is mounted as'is clearly shown in Fig. 3. The projection from the block 36 which is engaged by the rod 41 is indicated at 42 and is best shown in Fig. 6. This projection extends laterally from the block 36 and then downwardly and is provided at its lower end with a pin which enters a hole in the rod 4-1 so that the projection is readily disengaged from the rod when the carrier 19 is removed from the machine and the removal of the carrier ispermitted without disttu'bing the gage adjusting mechanism. The mechanism for adjusting the heel gage also includes a shaft 43 mounted in the forward end of the form carrying slidehin a vertical position at right angles to the rod 41. This shaft is provided with a pinion 44 which meshes with a series of teeth 4:53 on the foiwv'ard end of the rod 4-1, the construction being such that a mechanism against movement. These means as illustrated in the drawings and best shown in Figs. 7 and 8, consist of a locking arm 46 projecting laterally from the lower end of the shaft 43 and a series of locking teeth 47, arranged to he engaged by the arm, formed on a plate rigidly secured to a stationary block 48 on the under side of the slide 6. The shaft 43 is mounted so as to be capable of moving longitudinally and is pressed upwardly in a dire'ction'trrcause the arm 16 t0 enga e the teeth-17 by means of a spring 49 coi e around the shaft and seated between the bottom of a recess in the hlock 48 and the lower surface of the knob 50 securechto the upper en of the shaft 43 affords a convenient means for moving the shaft 43 to disengage the arm 46 from the teeth 47 and for rotating the shaft to adjust the heel gage.

In addition to the sole gripping and gaging devices hereinbefore described, the machine illustrated in the drawings is provided with an improved means for indicating the size of sole for'which the heel gage is ad justed. This means is extremely simple and compact in construction and efficient in operation and comprises a pointer 51 formed on the knob 50 and an annular scale plate 5! surrounding; the knob and provided with a series of numerals indicating the various sizes of shoe soles. This scale plate is mounted on the form carrying slide 6 concentric with the shaft 43 as best shown in is capable of adjustment to bring the numerals into the required position with Fig. 7, and relation to the knob 50 to indicate the sizes of soles of different kinds. The plate is held in adjusted position on the form carrying slide by means of a locking pin 53 screwing into the slide and provide with a flange extending into a circumferential groove 54 formed in the edge of the plate.

The soles which are operated upon by a sole molding machine are either completely rounded so that the edge of the heel end of the sole is curved, or are what are known in the art as'block soles, the heel ends of which present a straight edge at right angles to the longitudinal axis of the sole. in Figs. 9, l0, and 11 is illustrated an improved form of heel gage adapted for use with either of these classes of soles. This heel gage is similar in construction to the heel gage. hereinheforc described with the exception that. the arms forming the heel mounted so that they can be swung baclt into line with each other. In Figs. 9, l0, and 1.1. the two arms of the heel gage are in dieatcd at 55 and are mounted upon separate vertical pivots 56 on the gagecurryingbloek. The arms 55 are capable of being swung from the angular position illustrated in Fig. A to a position in which they are in line with each other, as illustrated in Fig. 10. To hold the arms in either position springpressed locking pins 57 are mounted in the gage carrying block engage notches 58 formed in the hubs ofthe arms. It will he noted that the pivots of the arms 5:") are separated a considerable distance. By reason of this arrangement of the arms they are adapted to engage and determine correctly the position of a t-Lf lltl of a given size, whether the sole is a rounded sole or a block sole, .uithout the necessity of any adjustment of the gage carrying block.
