SOLE-PRESSING MACHINE.

Specification of Letters Patent.

Patented Sept. 26, 1911.

To all whom it may concern:

Be it known that I, A oUs'rirs A. BALL, Jr..'a citizen of the United States, residing at Lynn, 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 descrip' tionof the invention, such as will enable others skilled in the art to which it appertains to make and use the same. ryTl'le invention relates to that class of sole pressing machines such as sole molding, sole aying, or'sole leveling machines in which the cooperating pressing forms are relatively .reci rooated to move them toward and away rom each other, and in which one of the forms is moved transversely to bring it. into and out of alinemcnt with coiiperating form.

The object of the invention is to provide an improved. mechanism for effecting the transverse movements of the reciprocating form into and out of alinement with the cooperating form, whereby the construction is simplified, and the movements of the form are accurately controlled without shock or undue wear upon the arts, and the form is securely held from isplacement when in its inner orouter position.

Tothesc ends, one feature of the invention contemplates the provision in a machine in which a jack or other form is mounted for transverse movement on a reciprocating head, of devices actuated by the relative movement between the head and its actuating mechanism for moving the form transversely into and out'of a moment with the cooperating form. Broadly considered, this feature 'of the invention contemplates the provision of any suitable devices 'throu h which the relative movement bet-ween t e reciprocating head and its actuating mecha- 'nism Will be translated into transverse movements' of the form carried by the head.

Inthe class of machines which the in.- vention is especially designed to improve, the reciprocating 'form carrying head is usuallyreciprocated through a toggle lever,

one link ormcrnber of which is pivoted to the head, and inaceordance with a fur ther "feature of the invention, the form is actuated ito move into and out of alinement with its cooperating form by this member of thehead actuating mechanism as the tog-' gle is straightened and broken in IBCl)lO- eating the head. This construction ena les the transverse movements of the form to be accurately controlled by connections which are simple in construction, and are compactly arranged. In the preferred form of the in vention the connections between the transversely movable form and the lever of the actuating mechanism which is pivoted to the head includes a cam which controls the position of the form upon the head, and which is so shaped that the form is locked in its outer position out of alinement with the cooperating form when the reciarocating head is retracted, and that the orm is moved into alincment with the cooperating form during the first part of the advance movement of the reciprocating head, and is then hold in fixed position upon the head during the completion of the advance movement ofthe head. This cam may be formed in the pivoted lever of the head actuating mechanism, or in the form carrier, or in a part'connected with the form carrier. It is preferred. however, to form the cam on a lever which is pivoted upon the reciproeating head, and is connected with the form, and to actuate the cam lever by ongagementwith the lever of the head actuating mechanism. It is also preferred to so form the cam that the form is under ositive control during the reciprocation o the head and the transverse movement of the form. y

The invention also includes certain further features and combinations which willbe hereinafter described and claimed, the advantages of which will be apparent to those skilled in the art from the following description of a machine embodying the invention.

The various features of the invention will be readily understood from an inspection of the accompanying drawings, in which- Y Figure 1 is a side elevation ofaj machine embodying the features of the invention intheir preferred form; Fig. ate a. side elevation partly in section showingithe devices for effecting; the transverse movements of the reciprocating form; and Fig. '3 is a; pear elevation looking from right to left in In the machine shown in thedrawin the forms for acting upon thlisole are' e signed and shaped to mold the sole prior to the lastingoperation. It will be understood. however, that the invention may be embodied in n'iachiucs designed for laying soles or leveling soles, in which case a jack adaph-d to support and carry a shoe will be mounted upon the reciprocating head, as is usual in machines designed for sole laying or sole leveling.

The machine illustrated is provided with two sets of sole molding forms, each comprising a fixed mold and a transversely movable mold carried by a reciprocating head. The heads are rcvorsely rcciprocated to bring one set of forms together while the other set is being separated, and the forms on the heads are moved forward and back during the recipmeation of the heads to advance the form when the head is in its retracted position. and to return the form into alinement. with its conu'ilen'ientary form during' the advance movement of the head. Since the devices for giving transverse movements to the forms on the reciprocal;- ing heads a re duplicates of each other, only one set of forms is illustrated.

As shown in the drawings, the fixed form 1 is carried upon the under side of a crossbar 2 by supporting andadjusting devices which may be of any suitable construction. 30 The transversely movable form 3 is. secured upon a carrier slide 4 mounted in a crosshead 5. The cross-head is mounted and guided upon vertical rods 6 in the usual manner. and is rcciprocated through a tog- :5 gle which is connected by means of a link 7 with a crank 8 on the shaft 9. The toggle "prises the two links or levers 10 and 11, vcr 10 being pivoted at 12 to the frame, anu the lever 11 being pivoted at 13 to the :0 reciprocating head. When the parts are in the position indicated. in the drawings the head a is in its lower or retracted position, and the form rat-lying slide 4 is in its forward position, with the form 3 in con- 5 venicnt position for the remowil of the molded sole and ill'. insertion of a new sole. When the shaft 9 is revolved the toggle is straightened to advance the head 5, and during the first part of the advance movement 0 of the head the form 3 is retracted to bring it into alinmucnt with the coiiperating form 1, and then during the final advance movement of the head the form 3 remains in fixed position upon the head so that the sole is 5 pressed between the forms by a. movement of the form 3 directly toward the form 1. \Vhen the toggleds broken and retlirncd to the position indicated in the drawings, the form 3 remains in alinement with the form 1 during the first. partof the downward movement of thehearl 5, and then during the completion of the driwnward movement, is moved forward out. of alinemcnt with the form and into the position indicated in the drawings.

the invention,

The mechanism for efiecting the transverse movements of the form 3 comprises a lever 14 pivotally mounted on the head 5 and connected with the form carrying slide 4 by a link 15. The lower end of the lever It is provided with a cam slot 16 which is engaged by a pin or roll 17 carried by an arm 18 which projects from the lever 11 of the head actuating toggle. The cam slot 16 is provided with a curved part 19 which 1s concentric with the pivot 13 of the lever 11 when the form 3' is in its retracted position in alinemcnt; with the form 1. The cam slot is also provided with a curved part'20 which is so shaped that the lever 14 is swung toward the left from the position indicate in Figs. 1 and 2 in advancing the head 5. The part. 20 of the cam slot is so shaped that the cam lever 14 is actuated to bring the form 3 into alinement with the form 1 with an accelerated and then retarded movement so that the form is rapidly and accurately moved and positioned without shock or jar, and with little wear on the parts. After the form 3 has thus been brought into alinementwith the form 1, the roll 14 rides in the part 16 of the cam slot during the continued movement of the lever 11 toward the left, so that the form is held securely in fixed position upon the head 5 during the completion of the movement of the lever 11, and durin the completion of the upward movement of the head 5. When the head 5 is retracted by mov ng the toggle lever 11 toward the right, the roll 17 moves idly in the part 19 of the cam slot during the first part of the downward movement of the head, thus retaining the form in fixed posi tion on the head, and then during the latter part of the downward movement of the head the roll cooperates with the part 20 of the cam slot to swing the, lever 14 about its pivot, and advance the form 3 into the position indicated. in the drawings, and to maintain the form in this position until theto gle is again straightened to advance t e he'ad 5. The trainsver'semovements of the form are thus efl'eeted through the swinging movement of'the toggle lever 11 about its pivotal connection with the head without shock or jar, and the movements ofthe form are accurately timed and positively controlled, and the form is securely held upon the head in both its advance and retracted position. Y

While it is preferred to employ the construction'and ah-angement of parts shown and described in practicing the invention, it will be understood and arrangement is not essential to the invention imits broader aspects, and may be modified and changed without departing from the invention. v
