3 Claims.

This invention relates to welt supporting devices, and is herein illustrated as embodied in a device of the portable type adapted to be applied to a welt shoe to support the welt against pressure applied to it through an outsole while the sole is being attached to the shoe by the cement process.

A welt supporting device of this type normally comprises a sectional frame arranged to surround the shoe and having a tapered inner edge arranged to enter the welt crease of the shoe while the device lies upon and covers the top face of the welt. In order to have sufficient strength and stiffness the welt supporting members must be so wide that they project beyond the edge of the welt and prevent the operator from seeing it, so that proper positioning of the shoe in accurate register with a sole upon the pressure pad in the sole attaching machine is difficult.

It is an object of the present invention to provide an improved welt supporting device which will be easy to apply to a shoe and will facilitate accurate registering of the shoe and outsole.

With this object in view, an important feature of the invention consists in the provision of sole positioning gages upon a portable welt supporting frame, said gages being so constructed and so related to a shoe embraced by the frame that they can function, almost automatically, to position an outsole correctly relatively to the shoe ahdpreserve the correct relation while the sole and shoe are subjected to attaching pressure, Without in any way interfering with manipulation of the Work in the attaching machine.

Invention is also to be recognized in an improved form of welt supporting unit which will support the welt of a shoe around the forepart and preferably along the outside of the shank portion, while leaving the shank portion of the Welt along at least the inside of the shoe unsupported and access thereto unobstructed so that it may be bent or pressed toward the shoe upper to produce the close edge effect which is desired at that place.

These and other features and advantages of the invention will be better understood and appreciated from reading the following detailed descrip tion of one good embodiment thereof, in connection with the accompanying drawings, in which Fig. l is a perspective view of the welt-supporting device, as seen from below;

Fig. 2 is a plan view showing the device clasped upon a shoe;

Fig. 3 is a view in cross-section showing the device clasped upon a shoe, an outsole registered with the shoe and the assembly positioned upon the pressure pad of a sole attaching machine: and

Figs. 4, 5 and 6 are views of details of the soleregistering gages.

Referring now to the drawings, the improved welt supporting device comprises a frame including a pair of plates I0, l2 hinged together by a pivot l4 at their toe ends and cut out along their adjacent edges l6, I8 to afford an opening conforming to the forepart of a shoe. The inner edges of the plates, surrounding the opening, are tapered, as shown at 20, to adapt them to enter the welt crease of a shoe, as illustrated in Figs. 2 and 3, wherein 22 indicates the upper and 24 the welt of a shoe upon a last 26. The usual insole and bottom filler of the shoe are indicated, respectively, by 28 and 30.

The welt supporting frame is adapted to be placed around the shoe and to be drawn tightly into the welt crease thereof by hand, a self acting locking device functioning automatically to prevent expansion of the frame from any point to which it is contracted upon the shoe. In the illustrated embodiment of the invention, this locking device consists of a dog 32 pivoted at 34 to the heel end of one of the plates I0, I 2 and having a hook 36 arranged for locking engagement with any one of a row of ratchet teeth 38 upon the heel end of the other plate. A spring 40 tends at all times to engage the hook 36 with the teeth 38, which latter are inclined in a direction to permit the frame to be closed freely about the shoe but automatically to prevent the frame from expanding unless the hook 36 is purposely released. This release is easily accomplished by pressing upon the tail end of the locking dog 32. Pivotally mounted upon the respective plates l0, l2 are pairs of

sole edge gages

42, 44, the pivots being shown at 46 and 48. The sole edge engaging faces of the gages are longitudinally corrugated, as shown at 50, in order to provide good gripping surfaces for engaging the sole.

The gages 44 are normally stationary relatively to the plate l2 upon which they are mounted but are adjustable about their pivots 48. To this end there is formed in each gage a slot 52 in which fits a pin 54 eccentrically mounted upon a short vertical shaft 56 to which is aflixed a knurled knob 58 having a hub 60 surrounded by a compressed spring 62. The shaft 56 also has an enlarged frusto-conical portion 64 arranged to fit a correspondingly shaped hole in the plate l2. The fit of these conically shaped parts is such that when the element 64 is drawn upward into the conical hole, as it normally is by the spring 62, the shaft 56 will be frictionally held against rotation and the adjustment of the gage about its pivot will be preserved.

When it is desired to change the adjustment of the gage the knob 58 is depressed sufficiently to loosen the element 65 whereupon the shaft 56 may easily be turned, the eccentric pin 34 causing the gage to be adjusted to the desired position. When the knob is released, the spring automatically reseats the conical element 64, locking the gage in adjusted position.

Upon the opposite plate l asi'milar pair of pivoted gages 62 are arranged to bear yieldingly against the outer edge of the shoe sole, which is designated by 86. upwardly turned lug 68, as shown in Figs. 2 and 4, and the ends of a torsion spring 10, which is mounted upon a fixed stud 12, bear against these lugs in a manner tending to press them outward and the sole edge engaging portions of the gages inward, so that the opposite edge of the sole 66 against which they bear will be positioned accurately against the fixed gages 44.

The heel ends of the plates l0, l2 are'continued inward as shown at M and are arranged to lie, beneath the heelend of the shoe, their forward edges being beveled at 16 to permit the pressure pad [8 of the sole attaching machine 80 (see Fig. 3) to'conform easily to the surface presented to it.

'As shown, the shape of the opening defined by the inner edges of the plates l0, l2 conforms to the forepart of the shoe and to the shank portion along the outside'of the shoe so that the welt 24 is supported continuously at these places. Along the inside of the shank portion of the shoe, however, the edge of the plate l2 departs from the welt crease of the shoe, as is apparent at 82 inFig. 2, leaving. this portion of the welt free and unobstructed to receive pressure from the pad 18 to bend or press the welt and inner shank portion of the outsole toward the shoe upper in order to secure the close edge effect which is desired at that place.

In the use of the illustrated apparatus, the

'locking dog 32 is'released and the plates l0, I2

are separated by relative movement about the pivot [4. The frame is then applied by hand to a welted shoe, the tapered edges 20 of the plates being introduced into the welt crease of the shoe Each of these gages 42 has an and the frame squeezed together by hand until it fits the shoe closely and supports the top face of the welt smoothly. The dog 32 automatically locks the frame and holds it securely in the position in which it has been clasped upon the shoe. A cemented outsole is next positioned against the stationary gages 46, which have previously been adjusted to cause the sole to be registered accurately with the shoe, and is held against the said gages by the spring-pressed gages 52 bearing against its opposite edge. rugated faces 50 of the gages, the sole will be By reason of the corheld'suiiiciently secure to prevent it from dropping oif, and the whole assembly can be readily picked up and placed upon the pad 78 of the sole attaching machine, where it may be moved about and positioned as desired without danger of disturbing the accuracy of register between the outsole and the shoe.

It will be noted that the whole apparatus is light and easily handled and that, while it serves its various purposes admirably, it does not interfere in any way with the operation of the sole attaching machine upon the shoe.

Having described the invention, what is claimed as new and desired to be secured by Letters Patent of the United States is:

1. A portable welt support comprising a pair of plates cut out along their adjacent edges to afford an opening conforming to the forepart of a shoe, said plates having tapered edges adapted to enter the welt crease of the shoe, a normally fixed sole positioning gage carried by one of said plates, and a yielding sole positioning gage carried by the other of said plates.

.2. A welt supporting unit comprising a frame arranged to surround a shoe, the inner edge of said frame being shaped to enter and occupy the Welt crease of the shoe around the forepart thereof and to leave the welt unsupported and access thereto unobstructed along at least one side of the shank portion of the shoe.

3. A welt supporting unit comprising a frame arranged to surround a shoe, the inner edge of said frame being shaped to enter and occupy the welt crease of the shoe around the forepart and along the outside of the shank portion thereof and to leave the welt unsupported and access thereto unobstructed along the inside of the shank portion of the shoe.
