21 Claims.

This invention relates to machines for shaping shoe parts and is herein illustrated as embodied in a machine for molding insoles or outsoles. The invention is also applicable, however, to machines for molding other objects such, for example, as reinforced insole units and the term sole as used herein is intended to cover any of the above.

An object of the present invention is to provide improved gaging mechanism for locating a work-piece on a mold. In the accomplishment of this object and as a feature of the invention a pair of gages are located above a sole-supporting mold for locating the heel end of a sole lengthwise and widthwise of the mold, these gages being adjustable as a unit lengthwise of the mold to accommodate soles of different lengths. Another gage located above the mold is engageable with the forepart of the sole for locating it widthwise of the mold and this gage is also adjustable to accommodate soles of different widths. An upper mold cooperates with this mold to shape the sole and, to avoid interference with the molds during relative movement thereof into pressing relationship, provision is made for swinging the heelend gages and the forepart gage outwardly to positions removed from the sole-engaging face of the mold. The heel gages are held above the sole-engaging face of the mold when in operative positions, so that they will clear the mold when they are swung outwardly. In order that the sole may be supported in contact with these gages, and in accordance with another feature of the invention, flanges are carried by the gages and are arranged to underlie the sole to support it above the sole-engaging face of the mold at a sufficient height so that it will contact the gages and not lie below them, thereby insuring proper gaging of the heel end of the sole. To facilitate rapid and easy adjustment of the gages and in accordance with a further feature of the invention, the adjusting means for the heel-end gages and the forepart gage are located in proximity to each other at the front of the mold so as to be readily accessible. Retraction of the gages is effected by cam followers connected to the gages and which ride over cams during relative movement of the molds into cooperative relationship. The forepart gage is so mounted that it is moved rectilinearly in a path normal to the longitudinal center line of the lower mold as it is adjusted widthwise of the mold. By so mounting this gage, its position lengthwise of the mold is not operating on soles of the same lengths but of different widths, the gage will contact the soles at the same positions lengthwise of them, thereby permitting accurate locating of the soles on the mold.

vention, one 'of the molds is mounted for horizontal adjustment both widthwise and lengthwise relatively to the other mold and is also mounted for vertical adjustment. The molds are so mounted in the machine that they may be readily replaced by other molds to adapt the machine to operate upon different types of soles. The mounting of one of the molds for horizontal adjustments in two directions is particularly advantageous as it enables the molds to be accurately positioned with respect to each other properly to shape the work, and thus compensation can be made for any variations that may occur in the relative positions of the molding surfaces in the molds of any pair that may be used. Variations in the heights of the molds are readily taken care of by the vertical adjustability of one of the molds, and this adjustability also provides for variations in the pressure applied to the work during the shaping operation.

These and other features of the invention will now be described in detail and pointed out in the claims.

cally movable cross-head 22. This cross-head is supported for vertical movements by a pair of posts 24 and is thus moved by mechanism including a toggle link 26 pivotally connected by a pin 28 to arms 30 depending from the crosshead 22. The toggle link 26 may be operated by any suitable mechanism such as that illustrated by Letters Patent of the United States 1,549,243 granted August 11, 1925 on an application of E. E. llVinkley.

The upper mold I2, which may be of unyielding material such as wood or metal, is adjustably supported above the lower mold I0. The mold I2 is carried by a cross-head 32 adjustable vertically on the posts 24. A screw 34 extends upwardly from the cross-head 32 and passes through a cross-head 36 rigidly secured to the posts 24. A nut 38, held against vertical movement in the cross-head 36, threadedly receives the screw 34 and provides easy and. accurate vertical adjustment of the cross-head 32 and the mold 12,

The mold I2 is mounted on the cross-head 32 for adjustment lengthwise and widthwise of the lower mold to permit it to be positioned in proper relation to the lower mold I0. Secured to the upper surface of the mold I2 is a dovetail-shaped strap 40 which is arranged slidably to engage a similarly shaped groove formed in the lower surface of a support 42. This support is secured to the cross-head 32 by screws 44 which pass through elongated openings 45 in flanges 46 on the cross-head 32. The elongated openings permit widthwise adjustment of the mold on the cross-head upon loosening the screws 44. To control the lengthwise adjustment of the mold I2 the strap 40 is provided with an upwardly extending end portion 4| that projects through a recess 48 (Fig. 7) in the support 42. The portion 4! is threadedv to receive a screw 50, the inner end of which engages the support 42 and the head of which bears against a plate 52. The plate 52 is secured to the adjacent end of the support 42 by screws 54. By turning the screw the strap 40 will be moved -lengthwise of the screw to effect a corresponding adjustment of the upper mold. To facilitate turning the screw 50 one of the screws 54 passes through a slot in the plate 52 (Fig. 1) so that upon loosening these screws the plate 52 may be turned upwardly to expose the head of the screw 50. Unintentional rotation of the screw 50 is prevented by a lock nut 56 which bears against the inner surface of the turned-up part of the strap 40.

It will thus be seen that the mounting of the upper mold is such as to permit ready adjustment heightwise, widthwise and lengthwise. The heightwise adjustment enables a variation in the pressure exerted on the work and permits the use of molds of different heights in the machine, the mounting of the molds being such as to permit rapid substitution of different types-of molds. Accurate alinement of the molds is permitted by the mounting of the upper mold for widthwise and lengthwise adjustment.

Accurate positioning of the heel end of a sole on the lower mold I0 is effected by a pair of heelend gages 66 (Fig. 3). These gages are mounted at the inner ends of arms 68 pivoted for swinging movement about vertical axes by pins I0 which are in turn carried by a support I2. This support is mounted for swinging movement about a horizontal axis by a pin I4 mounted in the upper end of an arm I6 (Fig. 2) extending upwardly from a slide I8. The pin 14 permits heightwise adjustment of the heel-end gages 66 so that they will be at the correct height to engage the heel end of a sole placed on the lower mold. The arm I6 carries a spring-pressed plunger which acts on an extension 82 of the support I2 to rotate the support around the pin I4 in a direction to move the gages 66 toward the lower mold. A stop screw 84 threaded through a bracket on the arm I6 engages the under side of the support I2 to limit this downward movement of the gages. Thus, by turning the screw 84 the heightwise position of the gages relatively to the lower mold may be varied as desired to meet different conditions of work. The gages are held slightly above the surface of the lower mold so that they may clear the mold as they are swung outwardly. So that the heel end of the sole may rest in contact with the gages, they are provided with flanges 85 which hold the heel end of the sole slightly above the adjacent surface of the mold. In the absence of these flanges, the sole might be slipped beneath the gages and would not be correctly positioned.

The slide I8 by which the heel-end gages are carried is mounted for movement lengthwise of the mold I0, thus permitting adjustment of the gages as a unit lengthwise of the mold to accommodate soles of different lengths. The slide I8 (Fig. 5) is provided with flanges 85 received by grooves formed in the upper surface of the support I8 directly below the holder I4. Rack teeth 88 formed on the under surface of the slide "I8 are engaged by a pinion 90 fast on the inner end of an adjusting shaft 92. The shaft 92 is journaled in a bushing 94 which is in turn secured by a screw 96 within a bore formed in the support I8. To the outer endof the shaft 92 is pinned a handle 98 to enable turning of the shaft and adjustment of the gages.

The shaft 92 carries an indicator I00 which cooperates with a pointer I02 secured to the support I8 so that the adjusted position of the gages may be readily ascertained. The indicator is adjustably secured to the shaft 92 so that the reading for any position of the heel-end gages may be varied. This adjustment is provided inasmuch as soles of different styles but of the same size may require a different position of the heel-end gages. Accordingly, by properly adjusting the indicator I00 in accordance with the style of sole being operated upon, the correct position of the heel-end gages for any size sole of that style may be obtained by setting them according to the size indicia on the indicator. The indicator is mounted between a plate I04 pinned to the shaft 92 and a disk I06 secured by a pin I08 against rotative movement relatively to the plate I04. A nut IIO, threaded on the shaft, provides means for moving the disk I06 toward the plate I04 firmly to clamp the indicator therebetween. However, upon loosening the nut H0 the indicator is free to be turned relatively to the plate I04 and the shaft 92 so that it may be set as desired. The disk I06 carries a pointer II2 to facilitate positioning the indicator I 00 on the shaft in accordance with the particular style of sole.

The gages 66 are adjustably secured to the arms 68 by pins II4 (Figs. 2 and 3) so that they may be swung relatively to the arms to any position desired. They are restrained against swinging movement relatively to the arms by detents H5 engageable between teeth IIB formed in the gages adjacent to the pins H4. The ends of the gage-supporting arms 6.8 adjacent to the pins (Fig. 3,) are formed with intermeshing gear teeth I so that, upon movement of one of the arms 68 to swing its gage. 66 laterally of the mold, an equal and opposite movement will be imparted to the other gage. Means are provided for swinging the arms 68 during upward movement of the lower mold I0 so that the gages 66 will be swung away from each other and separated sufficiently to avoid interference with the molds. For this purpose a Vertical plate having a cam surface I22 is formed at the end of an arm I22. secured to one of the supporting posts 24. A cam roll I26 (Figs. 1 and 8) is journaled in an arm I28 which is in turn pivoted at I30 between spaced arms I132 (Fig. 3) extending rearwardly from the. support l2. The arm I23, carrying. the cam roll, is connected to an extension I34 of one of the. gage-supporting arms 68, so that the arm is swung in a direction to move the gage outwardly of the mold as the roll moves upwardly over the cam surface I22 upon upward movement of the mold. The extension IN is adjustably connected to the arm I28 by a turn-. buckle I 36 into the outer ends of which are threaded rods ass having spherical heads I40. One of these heads is held by a leaf spring I 82 in engagement with a correspondingly shaped recess at the upper end of the arm I28 and the other head is similarly connected to the extension I34 of the arm 68. Hexagonal washers M l are fixed to the, rods I38 to receive wrenches so that the rotation of the rods may be prevented upon turning the turnbuckle E to vary the normal position of the gages 66 widthwise of the mold Iii. The gages are maintained in operative positions by a spring I 46 (Fig. 3) secured between. the support I2. and one of the arms 68 so that the cam roll I26 is held in engagement with the cam surface I22.

For positioning the forepart of the sole width.- wise of the lower mold Iii there is provided, as illustrated, a gage I56 which is mounted above the mold on a pair of links I52 and I .55 (Fig. 1). These links are pivoted at their upper ends to the gage I5 and at their lower ends to a bracket E56 extending rearwardly from. the support I3 so that they form a parallel linkage connection between the gage and the support. This arrangement permits the gage Ihil to be adjusted widthwise of the lower mold in a, straight line which issubstantially normal to the longitudinal center line of the mold. By so moving the gage as it is adjusted, it is always effective at the same location lengthwise of the mold so that, upon operating. on soles of the same lengths, the gage will contact the soles at the same points lengthwise of them regardless of variation in width. This permits .much more accurate gaging than in prior construction in which the side gage has been mounted for swinging adjustment about avertical axis, inasmuch as this type of adjustment causes the gage to swing in an arc and move both lengthwise and widthwise of the mold at the same time.

For adjusting the gage I50, a rod I60, having at. its. inner end an adjustable abutment screw I52. (Fig. 1) engaging the link I52, is arranged to be moved widthwise of the mold. The outer end of the rod I69 engages a cam I64v (Fig. 3) which is arranged to be rotated by an adjusting knob 56%. The. knob and the cam are both pinned to a shaft I68 (Fig. e) rotatably carried bythe support I8. The .shaft carries. an indicator Il-i! adjustably secured to the shaft in the same manner asv the indicator It!) associated with the heel-gage-adjusting mechanism. The indicator I70 may carry length markings as shown in Fig. 2, and width markings may be carried by a semicircular casing I14 secured to the support I8 and partially enclosing the cam I54. The adjustment of the gage I50 is effected by turning the knob I66 so that the proper length marking on the indicator IIIl coincides with the proper width marking on the casing I14. The link I52 is maintained in engagement with the rod I69 by a tension spring Hi6 connected between the arm I5d (Fig. l) and the bracket I56.

Unintentional rotation of th shaft I68 and adjustment; of the gage I50 is prevented by a spring-pressed plunger I which acts against a flange I 82 of the cam I64. A similar springpressed plunger ltd (Fig. 3) acts against the plate I04 associated with the indicator I00 to prevent unintentional rotation of the shaft 92 and adjustment of the heel-end gages.

The side gage I50 is moved rearwardly out of the path of upward movement of the mold I9 during the operation of the machine to prevent interference with the upper mold I2. For this purpose the arm I54 carries a cam roll I86 which is engageable with a cam surface I88 on a plate I89 secured to the adjacent post 24. During upward movement of the crosshead 2 2 the cam roll 586. is moved rearwardly by the cam surface I88 to cause rearward movement of the links I52 and I54v by which the gage I50 is carried so that the gage will be swing rearwardly simultaneously with the outward movements of the heel-end gages 66. The plates on which the cam surfaces I22 and I88 are formed may both be adjusted vertically on the posts 24 to vary the time during the upward movement of the mold it when the gages are retracted. This time is not varied however by the adjustments of the gages relatively to the mold.

The adjusting means for the heel-end gages and the side gage are located in proximity to each other at the front of the support It and the mold Iiiso that adjustment of the gage for different sizes of soles may be easily and quickly effected. Molds of other shapes for dilferent kinds of soles may readily be substituted for the molds I0 and I2. The mo-ld it may be removed and replaced merely by lifting it from the holder Id and placing another mold therein. To remove the mold I2, the plate 52 is swung upwardly whereupon the mold may be removed by sliding it lengthwise until it. is completely withdrawn from the support 42. Molds of different types for the shaping of soles of various styles may thus be easily and rapidly placed in the machine. The correct relative positioning of the molds to insure the proper shaping of the sole therebetween is readily effected by the adjustable mounting of the upper mold, which thus contribute to the adaptability of the machine to use molds of various shapes and sizes. The vertical adjustment of the upper mold not only permits the use of molds of difierent heights in the machine, but also provides for variations in the pressure applied to the work in the shaping operation.
