Application filed June 18, 1910. Serial No. 567,558.

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 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 sole pressing machines of the class which comprises cooperating sole pressing forms adapted to operate upon the sole before it is incorporated in a shoe, and more particularly to a gage device used in connection with machines of this type.

The obiect of this invention is to provide a gage which will accurately guide springheel soles both preliminary to and during the operation of the pressing forms upon the sole.

With the above object in view one feature of the invention contemplates the provision of a yieldinggage device normally in position to engage and position the sole when it. is laid upon the pressing form and capable of movement with the sole as it is forced against the form.

A further feature of the invention comprises an improved mechanism for causing the gage device to move synchronously with the sole as the latter is clamped to the form.

In the accompanying drawings illustrating the preferred form of the invention Figure 1 represents an elevation partly in section of a sole pressing machine with the improved gage device applied thereto. Fig.

2 represents adetail, with portions in section, of the cooperating sole pressing forms and improved gage device; and Fig. 3 is a plan view of the gage device and lower sole pressing form with the sole in proper position to be operated upon. I

The machine, a portion of which is illustrated in Fig. 1, is a double machine, being provided with two sets of cooperating sole pressing forms, the upper forms being stationary andthe loweriforms being reciprocated simultaneously in opposite directions toward and from the upper forms, and also being reciprocated horizontally from and toward a position of presentation into and out of alinement with the upper forms. Both lower forms are mounted and actu ated in the same manner and the sole gaging and gripping devices associated with each lower form are duplicates of each other. Accordingly, but a single set of forms has been illustrated in the drawings. The upper form, illustrated in the drawings, is lndicated at 1 and is removably secured in the usual manner upon a carrier 2 which is supported from the stationary cross-head 3 so as 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 vertically reciprocating cross-head 7. Reciprocating movements are imparted to the cross-head 7 from a crank shaft 8 bv 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 thebell crank being connected by a link 13 to an arm 14: integral with the 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 crosshead 7, the bell crank lever 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 the slide. The form carrying slide on the opposite side of the machine corresponding to the slide 6 is actuated by a similar bell crank 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 in spection of Fig. 1, when the reciprocating movement 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 sole gripping device comprises a gripping jaw 20 pivotally mounted at its rear. end upon the bracket 21 supported by jaw, a

the slide 6. The bracket 21- is formed intogral with a carrier 22 which is clamped-"to" the slide 6 by the cam 23 independently of the sole pressing form 5. The gripping jaw 20 is actuated to clamp the sole in position by a roll 24 journaled in the end of an arm projecting laterally from the horizontal arm of a bell crank 25 pivotally mounted on a bracket 26 secured to the cross-head 7. The roll 24 is yieldingly held in engagement with thejaw 20 by a coiled spring 27 supported on the rod 28 between the vertical arm of the bell crank 25 and a flanged por' lever 30 projecting rearwardly from the hub of the bell crank 25 serves as a convenient means for raising the roll 24 from engagement with the jaw 20 when the carrier 22 is removed from the machine.

The above construction is substantially the same as that shown and described in the patent to Preble, No. 1,004,075, dated September 26, 1911, and forms no part of the present invention.

The improved heel gage, which forms the subject of the present invention, is particularly useful where spring heel soles are be ing operated upon, for the reason that this type of sole does not conform to the shape of the sole pressing form when laid upon it,

i but the heel portion of the sole, owing to the condition of the leather, is held up above the lower form until forced down upon it by the gripping jaw, or by the upper form. In order to properly gage the position of this type of sole upon the form, the gage is normally positioned opposite the edge of the sole when the sole is first placed in the ma chine and is moved with the edge of the sole as the sole is clamped upon the surface of the form.

The gage comprises an arm 32 which is forked at its outer end to properly guide the heel portion of the sole, and consists of two fingers 33 and 34 extending at an I I angle to each other to embrace the heel. The

arm 32 is pivoted at its rear end upon the slide 35 mounted upon the rod 35, and is normally held in a raised position by the coiled spring 36 which engages the under side of the armand the upper surface of the slide 35. The upward movement of the gage .is'limited by a depending segment 37 which is provided with a recess 38011' one edge,

engaged by a stop pin 39 mounted. upon the slide- The gage 32 is arranged to be .ment of both is controlled by the gripping jaw 20, Upon upward movement of the gripping jaw 2 O,'the gage device will be forced back to its normal position by, the

spring, 36, and is limited in its upward movement by the recess 38 and pin 39. ,The sole is supported throughout its entire length by the lower form 5, which is recessed at l0 to project over the end of the carrier 22, and removably supported upon the carrier 6 in the usual manner. 7 The upper form 1 is provided with a vertical slot llto allow passage of the gripping jaw 20 therethrough. The slide and gage device mounted there on may be adjusted uponthe rod 35 by a connecting'rod 23 and operating mechanism, not shown, to adjust the gage to different sizes of soles.

the specific construction and arrangement of parts illustrated in the drawings above described, except where such constructlon and arrangement are specifically stated in the I the sole constructed and arranged to move with the edge of the sole as the sole is clamped to the lower form preliminary to the movement of the form into pressing position whereby the sole is accurately positioned upon the form, substantially as de scribed. V

2'. A sole pressing machine, having, in combination, upper and lower sole molding forms, means for clamping the sole to one of he present invention isnot limited to the forms, a heel gage positioned adjacent to one of the forms, and means for'moving the gage toward the surface of the form as the sole is clamped thereto preliminary "to the movement of the form into pressing position.

3. A sole pressing machine, having, in combination, cooperating sole molding forms, a gage mounted independently of the forms and normally spaced away from the surface of one of the forms to position the sole preliminary to the pressing operation, and means for moving the gage toward said form in a direction substantially normal to the surface of the form as the forms are moved toward one another, substantially as forms, a movable gripping jaw arranged to engage the sole and clamp it to one of the forms, and a gage for the heel end of the sole movable simultaneously with the gripping jaw and adapted to properly guide the sole before it is clamped in position, substantially as described.

5. A sole pressing machine, having, in combination, upper and lower'sole molding forms, a movable gripping jaw adapted to engage the sole and clamp it to one of the forms, and a gage for the heel end of the sole, actuated by the gripping jaw as the latter'is moved into a clamping position, whereby spring heel soles may be properly positioned relatively to the molding forms, substantially as described.

6. A sole pressing machine, having, in combination, upper and lower sole molding forms, a movable gripping jaw arranged to clamp the sole to the lower form, and a gage for the heel end of the sole normally held in a raised position and adapted to be moved downward upon movement of the gripping jaw to clamp the sole to the lower form whereby the gage is always positioned opposite to the edge of the sole, substantially as described.

7. A sole pressing machine, having. in combination, upper and lower sole molding forms, the lower form adapted to reciprocate relatively to the upper form, a movable gripping jaw operating to clamp the sole upon movement of the lower form in a rearward direction, a gage device for the heel end of the sole, and means normally tending to hold the gage device yieldingly in raised position, the gage device adapted to be engaged and moved downward by the gripping jaw upon movement of the gripping jaw to clamp the sole, substantially as described.

8. A sole pressing machine, having, in combination, a sole pressing form, a cooperating sole supporting form normally positioned out of alinement with the pressing form, mechanism for moving the supporting form inwardly into alinement with the pressing form and vertically to engage and press the sole between the two forms, a heel gage, and means for moving the heel gage toward the surface of the supporting form during the movement of the form into alinement with the pressing form, substantially as described.
