AppIicaticnOctcber 18, 1949, Serial No. 121,937 I (01. 18-47) 9 Claims. 1
This invention relates to new and useful improvements in devices for forming soles on shoes and especially relates todevices for forming composition soles on shoes, and constitutes a continuation in part of my co-pending application, Serial No. 670,740, filed May 18, 1946, and entitled iShoe Last, now Patent No. 2,507,505.
A main object of this invention is to provide a simple, strong, efficient, and easily operable device whereby shoes may be mounted on a universally mounted support so that in operating on them, for the purpose of forming composition soles thereon, the support may be quickly and easily swivelled around to present the shoe in a plurality of positions to the workman.
A further object is to provide a simple and efficient and relatively economical device on which the-shoe can be easily and quickly mounted to hold it firmly in operative position and condition for the reception of the composition sole by pouring the composition material into a-mold which is formed around the shoe while on the support.
A still further object is to enable the mold to be easily and quickly and accurately adjusted with respect to the shoe weld and upper and held in this relation while the sole material is setting after being poured.
A still further object is toiprovide a simple and efilcient device whereby the mold and its related parts may be easily adapted and adjusted, with respect to any shoe no matter what its size, so that in the matter of a few minutes, the same device may be adapted to firmly and efliciently hold shoes of all sizes.
Yet another objectis to provide simple means whereby prior to forming a composition sole on the shoe, the heel and inner sole may be separately and preliminarily treated to dispose them in the proper planar position and relativegpositio'n.
Further and more specific objects, features, and advantages will more clearly appear from a consideration of the detailed specification hereinafter set forth especially when taken in connection with the accompanying drawings which illustrate a present preferred form which the invention may assume and which form part of the specification.
In brief and general terms, the invention,
among other things, provides a supporting device for a shoe and this support includes a main frame orpedestal comprising outstretched spaced arms on a standard and preferably mounted so that the arms can be swung about a vertical axis 2 from a base surface such as the floor or a work table.
Pivoted within the outstretched arms of the main frame is a .secondary frame pivoted on a horizontal axis and at one end adapted to support a shoe. On this end of the frame, an adjustable plate is mounted to partly surround the sides of the shoe and provided with adjustable clamping and supporting plates which hold the shoe upper and welt in position, as well as to hold in placea molding strip of flexible material which runs around the welt and the entire shoe, to form a recess into which fluid composition may be poured to set and harden therein to form a sole for the shoe.
The adjustable plate on top of the, secondary frame has a three-point suspension, two of which is from the top of the secondary frame andra third is from the top of an adjustable leg dependent from the base of the plate and associated with the other end of the secondary frame so as to enable the operator to adjust theplate around the sho to differing sizes of shoe. This leg has means thereon to limit its motion in one direction with respect to the main pedestal so that one preferred position for working on the shoe may be easily and quickly be achieved without any particular effort.
A further feature of the invention is to'provide a spring pressure means to press on top of the shoe against the inner sole and the inner heel portion to assist in shaping them properly prior to the pouring of the sole composition and'to permit effective mounting of the shoe on the work support-and the proper shaping of itwhile on the support. This pressure means can be quickly applied and released and the distribution of the pressure may be varied along the shoe to suit it to shoes of diiierent sizes and also diiferent distorted conditions of the upper and inner soles and heels.
The preferred forms of the invention herein are illustrated in the drawings, of which: I
Fig. 1 is a side elevation, with certain parts in section, of the improved machine;
Fig. 2 is a vertical transverse section taken on the line 2 z of Fig. 1;
Fig. 3 is a plan view of the machine;
Fig. 4 is a vertical section taken on th line 44 of Fig. 3; and,
Fig. 5 is a plan view of amodified form of .the machine in which the machine can-supportand handle a plurality of shoes to (be treated.
Referring now merely to the specific forms 0f the device illustrated in the drawings and the construction thereof, it is seen in Figure 1, that there is a base member II] which can be screwed or bolted to a suitable surface or platform ll. Projecting upward from the top of the base It is a hollow standard sleeve [2 and projecting into said sleeve 12 is a stub shaft or stem [3 having an enlarged upper portion l4 adapted to rest on the top edge of the sleeve i2 and to be turned thereon at will. This stem [3 and the enlarged head 14, are integral with a frame member having a horizontally extending beam i5 and upwardly extending oppositely disposed arms l6 and IS on the ends of said beam i5. Extending vertically upward from these arms I5 and it, are adjustable rods or stems H and [1' having bearing sleeves l8 and [8 at their respective upper ends which have horizontal aligned axes.
Disposed to swing within the arms l6, l5, and rods H, H is another frame formed of vertical spaced elements l9 and 19' having at their upper ends, horizontally outwardly extending stub shafts 29 and 20' projecting into the bearing sleeves I8 and I8 respectively.
The lower portion of the frame of which the rods i9, is are side elements, is formed of a cross beam 2! suitably connected at its ends to the lower ends of the rods i9, i9. Along the upper edge of this cross beam 2| is adjustably disposed a clamping member 22, which at its lower edge, engages the beam 2| and also clamps between its members an upright rod or stem 23 the lower end of which is ball-shaped as at 24, to be gripped by the clamping device 22. At its upper end, this stem 23 is pinned between the free ends of a U-shaped metal strap 25, the intermediate portion of which is riveted to the narrow end of the sole plate 25 of the shoe last, as seen in Figure l and a shoe last block 26 which is more in detail shown and of the general form shown in my co-pending application, Serial No. 1
shoe having an upper 30 disposed over the last with its innersole 3| facing upwardly and the last is' adjusted to tightly grip it and be disposed therewithin. The sole has a usual welt portion 32 as seen most clearly in Figure 4. The clamping means 22 may be tightened by means of usual screws or bolts 33 as shown.
With the frame formed by the rods l9 disposed in a vertical plane as shown in Figure 1, and with the shoe supported horizontally on top of the stem 23 with the shoe last tightly in place, it becomes necessary to provide means around the welt 32 to form a mold for pouring composition material on top of the innersole 3|. To this end, I dispose a U-shaped plate in a plane substantially that of the welt and innersole of the shoe and this plate has a base portion 33' and spaced limbs 34 and 34' extending therefrom along the sides of the shoes as seen particularly in Figure 3. The limbs are respectively provided with elongate slots 35 and 35' upward through which extend threaded stems 36 and 38 mounted on or connected in any suitable manner to the upper ends of the elements [9 and I9 and forming continuations thereof. The plate rests on shoulders formed on the elements I9 and I9 and is engaged on its upper side by wing nuts 31 and 31, to
hold it in this position. The base portion 33' of this plate is held in proper position by reason of the projection upwardly therethrough of another threaded stem 33 with nut 39 on the upper side of the plate, and a wing nut 40 on the lower side. At the top of the stem 38 is a yoke element 41 with a cross pivot pin 42 therein to receive the forked end 43 of a long lever 44, the other end of which has a slot therein to receive a threaded stem 45, the bottom of which is provided with a collar 45 surrounding the threaded shaft 29 of the shoe last above described. The upper end of the stem 45 is provided with a wing nut 41 so that the lever 44 can be adjusted upwardly 0r downwardly as may be desired.
The lever 44 has a central elongate slot 48 therein to receive a thin bar 49 having a transversely disposed bottom edge 50. Along the bottom of the bar 49 are disposed springs 51 and 5| bearing against the bottom of the bar at their top and bearing respectively against a metal plate 52 and the inner heel portion 53 of the shoe as shown in Figure 1. Underneath the metal plate 52, there is generally disposed a layer of soft rubber, such as sponge rubber 54. The bar 59 has an elongate slot 55 therein, in which rides a pin 56 fixed in the lever 44 and extending across the elongate slot 48 therein. This pin allows the bar 49 to be moved longitudinally with respect to the pivot point afforded by the pin 55 and thus distribute the variations in pressure of the lever 44 on the springs 5| and 5| as desired. The purpose of this spring arrangement is to so press on the inner sole 3| and the inner heel portion 53, that they may be pressed fiat and even before any attempt is made to pour on a liquid composition sole. The pressure of these springs may be left on the parts thus under treatment for one or more hours after which, the lever pressure is released and the device is lifted out of the way for the pouring of the material in the manner to be now described.
The threaded stem 38 is anchored at its bottom in a lug 51 on a dependent leg 58. It is held in position thereon by means of nuts 59 and 60, as shown in Figure 1. Between the nut 59 on top of the lug 57 and the lug, there is disposed a slidable plate 6| slotted to be moved forward or backward and having a forward tapered face (52 to bear as desired against the top of the toe portion of the upper of the shoe, so as to help support the shoe in proper position, and it may be adjusted longitudinally to fit shoes of various sizes.
The dependent leg 53 has a bottom horizontally extending portion 63 the top of which passes through a notch 6 1 (Figure 2), in the cross member 2!. A threaded shaft 55 passes through a threaded bore in the cross member 2i and is journalled in flanges 56 and 67 of the leg 58 and has a hand knob 58. The turning of the threaded shaft will move the leg horizontally to adjust it and the mold supporting plate 33' with respect to the shoe as is clear. The leg 58 along its bottom portion, is provided with a slot 69 through which extends a bolt 70. This bolt, when tightened, is associated with straps H and I! fastened to the bottom of the cross member 2| and disposed on either side of the horizontal portion of the leg 58. This will permit the leg 58 to be adjusted, and then this adjusted relation is fixed by tightening up on the bolt 70 to hold the leg and therefore, the plate 33' in proper relation for any given shoe. Along the bottom of the horizontal portion 63 of the leg 58, are disposed adjustable stop clamps 72. These clamps are adapted to abut an eccentric cam disc 13, which is adjustably disposed on top of the mid portion of the "main :frame "I Svmi'dway between the limbs or legs I6 and I6. Thus it will be seen that the secondary frame may be swung around the horizontal axis of the stub shafts 20 to invert the shoe at will and then can be moved back to the position shown in Figure 1, to present the bottom of the shoe upwardly in a predetermined position determined by the setting of the clamps 12 with respect to the disc 13.
With the mold-supporting plate shown in Figure 3, having a base portion 33 adjustablein a horizontal plane with respect to the shoe, the inner sole and welt are surrounded by one or more strips of flexible material to form a wall surrounding the inner sole and heel thus resulting in a recess into which may be poured fluid composition to form a sole and heel when set. The limbs 34 and 34' of the plate 33 at the sides "of the shoe, are provided with lower adjustable plates 15 and with upper adjustable plates 16. These respective plates are slotted to be slipped in position and to embrace a bolt l1 passing through the limbs of the plate '33 and with wing nuts 18 above and below the limbs to hold these plates in adjusted position. The lower plates 15 extend beneath the lower edge of the flexible strips to hold them in position and the upper plates I6 are adjusted to bear against the side of the strips to hold them in proper relation with respect to the inner sole and welt. The lower plates have four sides of different curvature so that these sides may be selectively used to be disposed with shoes of'different shapes and sizes at will. The tapered face 62 of the plate I 6| has connected thereto in any suitable manner, an elastic band 85 which, as shown Figure 1, extends therefrom on each side of the shoe and passes around the flexible strip '54 at the bottom thereof, where it is disposed around the heel portion 53 of the shoe. This elastic connection permits this portion of the strip to be firmly held in place.
At the sides of the shoe elongated bearing plates 19 are provided and are supported on the inner ends of strips 80 adjustably disposed beneath the limbs 34 and 34' of the mold supporting plate, and are held in position by means of the wing nuts 31 and 31' previously mentioned.
In order to guide the lever 44 in its up and downward movement, there is connected thereto a cross bar 8| which is connected thereto by means of U-shaped straps 82 bolting the cross bar Bl to the underside of the lever 6%, as shown in Figure 2. The ends of this bar Eli are bored to receive the upper ends of the threaded stems 36 and 36, so that as the lever is moved up and down, the cross bar will be guided on these stems in a controlled movement. Wing nuts 32 limit the upward movement of the bar 81.
In Figure 5, is shown in a schematic manner, the mounting of a pair of such formers on a single mounting, each one of which may be manipulated to swing around a horizontal axis and both to be swung as a unit around a central vertical axis.
In the operation of this simple and efficient device, it will be seen that it will enable a shoe to be held in position to be worked on and to be manipulated to present it with its sole portion down or up as desired, by merely turning the secondary frame on its axis in the main frame. In operating the device, the shoe is prepared by inserting the last therein to fit tightly therein and the stemfrom thelast projects downwardly andiis clamped in. the manner described to clamping means associated with the ,cross :memher at the bottom of thesecondary .frame member. Thisv therefore, wvill present theshoe with its inner sole and Welt facing upwardly in a plane substantially flush with the upper end of the secondary frame and in a;plane substantially the same as the mold supporting plate 33' which .is adjustab-ly mounted on the upper end of this secondary frame, through the intermediary of the dependent leg which can be adjusted by means of the threaded shaft associated between the cross member of the secondary frame and the lower horizontal portion of the dependent leg. This adjustment depends entirely upon the type and size of the shoe .to be disposed at the top of the frame as must now be clear.
If the inner heel portion and the inner .sole portion are somewhat out of shape andnot disposed flat, it may be necessary to apply the lever 44 to exert pressure on these portions through the intermediary of the springs disposed under the lever in the manner heretofore described. This will permit these portions to be pressed out fiat for a suitable length of time before the molding strips are applied around the inner sole to pour the liquid .material into the mold chamber to form the sole and heel. After this suitable length of time, the lever 44 with its associated elements is raised and the mold supporting plate is adjusted to position with respect to the shoeinner sole and welt by turning the threaded shaft :at the bottom- 01" the dependent leg and associated with the cross member of the secondary frame. This will adjust the plate with respect to the inner sole and welt and will permit the adjustable elements on said plate to be adjusted to support the mold strips around the sole and welt and to bear against said strips to hold them in intimate contact with the inner sole and welt. This adjustment also applies to the elongate strip bearing elements at the side of the shoe. After all these adjustments are made, it is then that the material to form the sole and heel are poured into the mold recess, which isallowed to set after which the shoe can be removed.
It is therefore, seen that I have provided a main frame rotatable around one axis with a secondary frame supported therein rotatable around another axis at right angles to the first axis. The secondary frame supports a shoe with its sole presented in a plane substantially flush with the end of the frame and at right angles thereto, and the secondary frame also supports a mold-supporting plate atright angles to said end and in a plane substantially coincident with the plane of the sole and heel with means to adjust the mold-supporting plate with respect to the sides of the inner sole and the welt. Means are provided on the mold-supporting-plate to support a mold strip around the welt and inner sole and to press it into proper and inti-' mate contact with said inner sole and welt to form a proper recess for pouring liquid material into said recess or mold to set.
It is apparent that the shoe in the operative position may be even more firmly held by the forward movement of the plate 6!, with the forward tapered face to bear against the outer toe portion of the shoe upper and that the adjustability of this plate will adapt the contact of this tapered portion to shoes of various sizes without any particular difficulty whatsoever.
