To all whom it may concern:

Be it known that I, BENJAMIN F. MAYO, a citizen of the United States, residing at Salem, 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.

T he present invention relates to sole pressing machines and is designed primarily as an improvement in machines for pressing or molding soles before they are incorporated in a shoe, although various features thereof are also applicable to other forms of sole pressing machines.

lhe present invention has for its object to improve the construction and arrangement of the various parts of sole pressing machines and particularly the construction and arrangement of the mechanism for supporting and actuating the sole pressing forms, whercby the soles can be supplied to and remover from the forms more conveniently and rapidly, and whereby such machines are rendered simpler and more compact in construction and more e'flicient and satisfactory in operation.

Sole pressing machines as usually constructed are provided with two sets of forms which are brought into operation alternately to press a sole, the forms of one set being in a position which allows a sole to be removed therefrom and another sole to be supplied thereto While the forms of the other set are pressing a sole. T hose features of the present invention which relate to the improved mechanism for supporting and actuating the sole pressing forms are embodied in a machine of that type in which the forms of both sets are simultaneously moved toward and from each other to produce pressure and clearance between the forms and in which. form of each set is moved into and out of line with its cooperating form in order to allow a sole to be supplied to one set of forms while the other set 18 pressing a sole. In accordance with the present invention the forms which are moved out of line with their cooperating forms are moved alternately to a position between the cooperating forms. This mode of operation necessitates only a comparatively short movement of the forms and allows the various parts to be arranged in a simple and compact manner, which conduces to the strength and durability of the machine and to the convenience with which it can be operated. Broadly considered, it is immaterial to the present invention which forms are moved into and out of line with their cooperating forms. t is preferable, however, to move the forms upon which the soles are placed and by which they are supported during the relative movements of the forms to produce pressure and clearance, as thereby the advantages enumcrated above are secured and the further advantage that the forms are presented alternately in a convenient position to receive the soles and permit their removal. A feature of the present invention, therefore, contemplates moving the sole supporting forms alternately to a position of presentation between the cooperating forms. In order to add still further to the convenience with which the soles can be removed from and placed on the sole supporting forms, the present invention also contemplates imparting an additional movement to the sole supporting forms which brings them out toward the front of the machine, so that their position of presentation is in front of as well as between the cooperating forms.

In addition to the features of invention above referred to the present invention consists in the combinations and arrangement of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art.

The various features of the present invention will be clearly understood from an inspection of the accompanying drawings in Whiel Figure 1 is a view in front elevation of a sole molding machine embodying the same in their preferred form, a portion of the reciprocating cross-head being broken away to show the toggle for actuating the same; Fig. 2 is a view in side elevation of the machine; Fig. 3 is a view in rear elevation; Figs. 4: and 5 are detail plan views illustrating the construction by which the lateral and in and out movements are imparted to the sole supporting forms; 6 view illustrating the construction and ar rangement of the wedge for adjusting one of the uoper forms and Fig. 7 is a detail sectiona view of the mechanism illustrated in Figs. 4 and 5.

is a detail sectional 1 and 2 indicate two sole pressing forms which may be conveniently termed sole supporting forms, as the soles are placed upon these forms and are supported thereby during the sole pressing operation.

3 and 4.- indioate two sole pressin forms which cooperate respectively with the forms 1 and 2. During the operation of the machine the upper forms 3 and 4 remain stationary and the forms 1 and 2 are rccipro-' cated simultaneously toward and from the upper forms. In addition to the vertical reciprocating movements which are imparted to the forms 1 and 2 to produce pressure and clearance, a lateral movement isiinparted to the forms and also an inward and outward movement so that the forms 1 and 2 brought alternately to a position in front of and between the forms 3 and i, a form when in this position being convenient of access by the operator, so that a molded sole can be readily removed from the form and another sole placed thereon. This position of the forms may be conveniently termed position of presentation.

The sole supporting forms 1 and 2 are mounted upon blocks 5 and e which are provided with dove-tail projections which are received in guideways in a carrier 7. The carrier 7 is mounted to reciprocate laterally upon the upper end of a cross-head 8 mounted to reciprocate upon vertical guides on the machine frame. The movements of tire sole supporting forms 1 and 2 toward and from the forms 3 and 4 to produce pressure and clearance are secured by reciprocating the cross-head 8 on its'guides and the lateral and inward and outward movements of the solo supporting forms are produced by the lateral movements of the carrier 7 on the cross-head and by the inward and outward movements of the blocks 5 and e on the carrier.

Th cross-head 8 is reciprocated by means of a toggle 9 which is actuated by means of a link 10 from a crank on a shaft 11, mounted in bearings in the rear portion of the machine frame. This shaft is driven from the main driving shaft 12 through a series of gears 13, 14, and 16, the gears 13 and 16 being secured respectively to the shafts 11 and 12 and the gears 14 and 15 being secured to an intermediate shaft 17.

The carrier 7. cross-head 8 by means of two cams 18 and 19 mounted upon a shaft 20 and arranged to alternately engage aroll 21 mounted upon a stud projecting from the carrier 7. The shaft 20, is driven from the shaft 11 by means of intermeshing gears 22 and 23, the proportion of these gears being such that the shaft 20 makes one complete revolution during two complete revolutions of the shaft 11. The cams lg and 19 are so arranged that the cam 18 acts to move the carrier 7 in one direction during one revolution of the shaft 11 is moved laterally on the to bring the form 1 in line with its cooperating form and the form 2 into a position between the forms 8 and 4tand the cam 19 acts to move the carrier in the opposite direction during the next rotation of the shaft 11 to bring the form 2 in line with the form 4 and the form '1 into a position between the forms 2 and 4. The two sets of sole pressing forms are thus actuated alternately to press a sole, one of the sole supporting forms 1 and 2 being in a position which allows a molded sole to be removed therefrom and another sole to be placed thereon, while the other sole supporting form is cooperating with one of the forms 3 and i to mold a sole. The inward and outward movements of the forms on the carrier 7 is for the purpose of bringing the forms into a position in which they will be more convenient of access by the operator and these movements in the construction illustrated are produced by the lateral move ments of the carrier 7. To this end a short vertical shaft 24 is journaled in the carrier 7 and is provided upon its upper and lower ends with pinions 25 and 26. The pinion 26 meshing with a rack 27 upon the cross-head 8 and the pinion 25 meshing with racks 28 and 29 upon the blocks 5 and 6. By this "con struction the shaft 24 is rotated first in one direction and then in the other by the lateral movements of the carrier 7 and the blocks 5 and 6 and the forms mounted thereon are simultaneously moved inwardly and outwardly in opposite directions. The inward and outward movements of the forms 1 and 2 take place simultaneously with the lateral movements of the carrier 7 so that the forms move diagonally from a position in front of and between the cooperating forms to a po sition in line with their cooperating forms. The sole supporting forms are brought alternately into substantially the same position in front of and between the cooperating forms, the movements imparted to the forms being comparatively slight and the position being that in which the forms are most conveniently accessible by the operator.

The upper forms 3 and 4 are mounted upon the lower ends of vertically adjustable crossheads 30 and 31 which are mounted to slide in guideways on the machine frame. These cross-heads are supported from the stationary cross-bar which forms the upper portion of the machine frame by means of adjusting wedges 32 and 33 which are mounted in guideways in the frame of the machine and in the cross-heads 30 and 31 and provided with projecting flanges engag ng undercut grooves in the frameand in the cross-heads, so that an adjustment of the wedges moves the cross-heads and the forms 3 and 4 mounted thereon positively toward and from the i forms 1 and 2. The wedges are adjusted by means of ad usting screws 34 and 35 mounted-in PIOJQCUODS extending upwardly from the wedges and screwing into the machine frame. As a means for assisting the operator in adjusting the forms 3 and at to produce the required amount of pressure, pointers 3e are secured in the frame of the machine and are arranged to cooperate with the scales 37 upon the cross-heads 30 and 31.

In the machine illustrated in the drawings the pressure required to mold the soles is produced by the direct upward thrust of the cross-head 7 and this thrust is resisted by the cross-beam which forms the upper portion of the machine frame. In order to more rigidly hold this cross-beam in place and also relieve the side standards of the frame from severe strains and render the entire frame of the machine more rigid and durable, clamping rods 38 are provided at each side of the side standards which pass through slots in the cross-beam and in the base of the machine.

The operation of the machine illustrated in the drawings has been snfliciently indicated in connection with the description above given and will be readily understood by those skilled in the art.
