To all whom t may concern.' y

Be it known that l, VILLIAM C. STEWART,

a subject ot the King of Great Britain, re-

chines, slashing machines, skiving machines, molding machines and rounding machines, the sole is located preparatory `to being op`` erated upon by either a toe or a heel gage, or by a combination of such gages. The ditlerent Widths of the saine size and style ot a sole, and also the different styles otl soles of the same size and Width `vary in length. Vlhis variation `in the length does not always occur at the toe end, or at the heel end, but may occur at both ends, and

for this reason the use of toe or heel gages to locate soles of different sizes, Widths and styles in machines ot the classes above referred to is troublesome on account of the many dil'ierent adjustments required, and

often leads to inaccurate and unsatisfactory:

results.

rlihe primary `object ofthe present invention is to provide an improved and si.mpl1 lied means for lo fating'soles in machines ot the classes above referred to, Which will b e free Jfrom the obiectlonable `features inci dent to the usey ot heel or toe end gages.

In accordance With this object, one feature of the invention contemplates the pro# vision, ina machine for operating on soles Which has devices With relation to Which a sole is to be located before being operated upon, of a sole locating device having a eeler to cooperate With the edge contour of the sole to determine the longitudinal position of the sole.

n the illustrated embodiment oie the invention, the sole locating device is employed to position a sole on the mold of a sole moldi ing machine so that the ball line of the sole will register iviththe break on the face of the mold.

Accordingly, another feature of the invention contemplates the provision in a sole molding machine having coperating molds, of means forlocating a sole in the proper position With `relation to the molds includ-` ing a i'eeler cooperating Withthe 'edge contourof the sole to determine the longitudinal position ot' the sole. In the simplest and most .etlieient form of the invention Which has yet been devised a pair of centering gages are arranged tocontact With oppo=` site sides of the sole and a feeler mounted upon one ot' the gages and coperating With the edge contour of the sole serves to con`` trol a mechanism which locks the tivo gages against transverse movement When the sole has been located in a predetermined long-i` tudinalposition. i

The invention also includes other features of construction and a combination of parts,

which are hereinafter described and set forth in the claims.

The various features ot the invention are illustrated in the accompanying drawings, in` `Which Figure 1 is a view in side elevation illustrating a sole molding machine embodying the preferred form of the invention; Figs. 2, 3 `and are detail plan vieivs -of one of the pressing molds, showing the diiierent positions which the solo locating mechanism occupies with relation to the mold; Fig. 5 is a detail view in front elevation of the mold and sole locating device shovvn in Fig. 2; Fig. Gis a vertical section through the mold taken on the line GWG'O Fig. l2, showing the heel centering fork; Fig. 7 is a diagrammatic vievv illustrating the different lengths for the diierent Widths of solesot' the saine size and style; and Fig.

8 is'a diagrammatic vieiv illustrating the different lengths ot soles for the different styles ot soles ot' the same size and Width.

`The sole `pressing machine illustrated in the dravvings is substantially the Same in its construction and operation of parts as the sole pressing machineshown inthe patent to Preble, No. 1,004,076, patented Septenr ber 26, 1911. This'machine is provided With tvvo sets of sole molds, but inasmuchas lootli sets ot molds are constructed and op-` erated inthe same manner, one set only Will the position shown in Fig. 1 the lower mold is located in the position of presentation out of .alinement with the upper mold. During the initial movement of the active stroke of theV crank 20 theY lower mold 1st is brought into an alined position with the` upper mold 10. To accom alish this, the slide 1G is connected by a lin 26 with la bellcrank 28 pivoted von the carrier 18. rllhe bell'crank 28 isfconnected by means of a link 30. with a lever 32 which is pivoted in the machine -trate the variation in the frame,and has one'arm attached to a spring 34 which is connected to the machine frame. With this Yconstruction the initial movement ofthe carrier will bring the slide 16 back against a stop 36 on the carrier 18, in which position the molds are i-n alinement. lith the continued operation ofthe crank 20 to bring thefmolds into pressure relation, the toggle 24- is straightened and the movement of the slide actuating mechanism is taken up in the spring 34. Y Y

The parts so far described areV the same las thoseY illustrated and described in Vther patent above referred to, and reference is hereby made to said'patent for a. detailed description of the construction and opera.- tion-of these parts.

The principal operation performed by the sole molding machine Yis to form a sharp bend in the sole at the juncture of the shank and forepart, or what is known as the .ball line of the sole. This sharp bend in the sole mold is shown at 38 in Fig. l, and designated by the line 38 in Figs. 2, 3 and 4. To properly moldthe sole, the ball 'line of the sole should be made to coincide with the line 38 on the mold. In Fig. 7 is shown the'outline of' a series of patterns of inished soles vofthe same size and style, which illuslength of soles for di'erentwidths. Each ofthese soles has a different length, and the ball lines of all Vdo Vnot coincide.l In Fig. 8 are shown diagrams of a! series of patterns ofvlinished soles yof the same size and width, which illustrate the variation in length of soles for the different styles. In this view, the Iball lines of the sole coincide, and the soles vary in length at each side of the ball line. It is apparent that the use of a heel or a toe gage to locate 4even -a finished sole with respect to the ball line of a mold is aptY torproduce inaccurate results.

When operating, however, on block soles, such as Villustrated in dot and dash lines in Figs. 2, 8 and 1, in which only the shank and forepart of the sole has been shaped, measurements with reference to the heel or the toe ends would lead to even more inaccurate results. This is true, especially in the case in which block soles are employed in making soles several sizes smaller than the rough size of the block sole.

To accurately locate the ball line oi' a block sole on the ball line of the mold with the locating mechanism illustrated in the drawings, a pair of centering gages are en ployed which contact with opposite edges of the sole intermediate its ends, and locate the sole by reference to its contour. The centering gages l() and a2, Figs. 2, 3, 4f and 5, are arms projecting from lhubs 4i-1 and l-o, respectively, which are pivoted on an adjustable block 18. The block 48 is mounted on the slide 16, and is adjustable transversely thereof by means of slots 50 and set screws 52, to permit the gages to be accurately .positioned with reference to the different types of molds. As. shown in Figs. 5 and 6, the upper face of the mold 1l is beveled from its center line toward the edges, and consequent-ly the hubs H and #lo are set on an angle to permit the gages to move toward and from each other substantially parallel with the face of the mold. Lugs 54 project forwardly from the hubs 4e Vand 4G, between which is connected a strong tension spring 56, that acts to normally close the gages toward the center of the mold. The gages are geared together by means of interineshing gear segments formed on arms 58 and 60, which project from the hubs 4-/1 and 46, respectively. When a sole is in place between the gages, one edge contacts with a roll 62 on the gage y10, Fig. 5, and the opposite edge contact with a pair of rolls 64: on a feeler 66, which is pivotally mounted in the forward end of the gage l2. Vth this construction the spring 56 will cause the gages to follow the contour of the sole and since the gages are gea-red together' they will center the sole.

Then the lower mold 14 is in the position of presentation illustrated in Fig. 2, the eel tering gages are held apart. a sullicient distance to permit the shank portion of a, solo to be readily inserted between them. To this end an arm G8 pro-jects back from the gage 40,-and carries a roll 70, which enga ges a cam vface 72 formed on a cam plate 7 4. The cam plate 74 is'adjustably mounted by means of slots and lbolts 7G upon the carrier 18.

To position a sole with the locating device, the shank portion of the sole is placed between the gage 410 and feeler (50, and pushed back toward the heel end of the, mold. As the sole is moved back, the gage Llvtl'and feeler 66 follow the contour of the sole upon the mold.

sole andare spread apart the forepart or' the sole is advanced between them; When the ball line of the sole has been brought into register with the ball line of the mold, the 'eeler acts tolock the gages from furthea,1 spreading movement, and holds the sole from further advancing movement. To accomplish this result, a link 7 8 is Vconnected between the feeler 60, and a pawl 8() which is pivotally mountedionthe gage 42. rl`he pawl arranged to engage with a ratchet plate 82, which is pivotally mounted on the stud 84, upon which the gage 42 is pivoted. A gear segment 86 is formed on the ratchet plate which meshes with a gear segment on an arm 88 iiXed by means of dowel pins 90, and a screw 92 upon the arm 58. The pawl is normally held in engagement with the ratchet 82 by a spring 94 which is connected between the tail ofthe pawl and the gage "When the feeler is in engagement with the shank portion of the sole, as shown in Fig. 2, it will be rotated by the gagespring 56 into such an angular position on the 42 that the pawl 80 will be drawn out o1 en-` gagement with the ratchet 82 against the action of the spring 94. With the ratchet unlocked, the gages are free to spread apart as a sole is moved through them; `As`the solcis moved through the gages fthe fceler will 'follow the sole edge contour and will be rotated suiiiciently by the change of curvature oi2 the sole, when the ball line of the sole registers with the ball line of the mold, to permit the pawl 80 to engage the ratchet 82. The engagement oi' the pawl with the ratchet looks the gages `from further spreading movement and holds the sole from `advancing further through the gages. The angular position olf the eeler 6G on the gage 42, when the gages are locked, is shown in Fig. 8. This position is determined when the contour of the sole edge changes from divergent to the center line of the mold, to convergent to the center line of the mold, or approximately the Widest portion of the solo. The movement of the ratchet plate 82 by the arm 88 is very rapid since they are geared to a hiO'h ratio, and the ratchet teeth can be comparatively large to positively lock the gages from spreading movement when the :teeler has reached the proper an` gulai.'` position upon the gage 42. By the above construction, the sole is positioned entirelyhy reference to the `contour of the sole edge. Since the gages follow the contour of the sole and locate the soleby reference to its yedge curvature they do not need sepa 'ate adjustments to provide for the diferentsizes and widths of soles. It will be seen that the eeler, in addition to determining thelongitudinal position of the sole on themold, also ccperates with the gage 42 in centering the rlhe operation of the sole locating feeler dependsupon its angular position uponthc gage, so that the heel end o'tf the sole should be centered to insure that the ball line ot the sole will be brought into register with'the ball line of theniold when the r'eeler operates to lock the gages, and to insurethat all of the soles will 'be uniformly positioned. The heel end of the sole is centered by a pair of spring clips 96 which form a fork to receive the heel end of the sole, see Figs. 2, 8, 4 and 0. lThe clips are secured to the blocks 98, which are. slidably mounted upon a rod 100, supported on a carrier 102. An adjusting screw 104, having' a right and left thread, is fixed in the carrier102 and threaded into the "blocks `98 so that the movement of the screw 104 will give the clips 96 a relative receding and approaching movement. The carrier 102 is slidably mounted upon 'a rod 10G which is secured! between the mold 14 anda. bracket 108 secured to the slide 16, and the Icarrier may be adjusted in different positions on the rod for treating different lengths of soles. j i

As will be observed in Fig. 8, the ball line of a sole occupies different angular relations relatively to the center line of the sole for the different styles. For this reason the heel clips may be adj usted to propely center the heel end of the sole and the link 'T8 connecting the gage :feeler `(3,6.and pawl 80 is made adjustable by means of a slot 110 and screw 112 to permit the feeler G6 to be set to occupy different angular positions for locking the ratchet by the pawl 80. By this adjustment and the adjustment of the gage block 48 transversely of the slide 10, the angular relation of the ball line of the various styles of soles can be made to register with the ball line 3S of the mold 14.

`As shown in Figs. 2 and 8, the gages move back and forth across the vfaceoif the mold and lnust be withdrawn from the sole to allow the sole to be molded. This result is accomplished when the mold 14 is moved from the position of clearance into aline ment with the upper mold 10. During this movement the sole is automatically clamped in'position upon the mold 14, and the side gages withdrawn from the face of the mold 14, so that the upper mold 10 can be brought down into contact with the sole. The sole is clamped in position by a clamping arm 114 which is iXed on a shaft 116 pivoted in the bracket 108. A cam lever 118, Figs. 1, 2, 3 andG, is fixed on the shaft 116, and carries a roll which works in a cam groove 122 formed in a plate 124secured to the carrier 18. The movement of the roll 120 in the cam groove 122 operates to bring the clamping arm down to clamp the sole between a face 126 on the arm 114, and a plunger 128 mounted in the mold 14.

` Before the side gages can be spread away clear of the mold 14, the pawl 80- must be released from the ratchet 82 to permit the gages to be spread apart. To this end a cam plate 180 is loosely mounted upon the stud'84, and is provided with a cam groove 132whioh engagesa roll 134 on a plate 136 adjustably mou-nted upon the carrier 18 by means of slots and bolts 138. then the mold 14 is in the position of presentation, the cam plate is in the position shown in Figs. 2 and 3, and vas the mold is moved into alinement with the upper mold, a face 140 on the plate 130 engages a roll 142 on the paw] 80, and lifts the pawl clear of the teeth of the ratchet 82, as shown in Fig. 4. The

link k7 8 has a slot 144 which permits a movement of the link relatively to the feeler 66 while the pawl is being unlocked from the ratchet. WV hen the cam plate 130 has been operated to unlock the pawl from the ratchet,

Y the roll 70 on therarm 68 is timed to engage Vwith a cam vface 146 on the cam plate 7,4, and

spreads the side gages to the position shown in Fig. 4. The gages remain in this position while the sole is being pressed, and when the mold is moved into the position oiz clearance, the cam plate is moved back into the position shown in Fig. 2, to arrange the gages so that they vwill be ready to position another sole.
