9 Claims.

This invention relates to shoe supports, the term shoe being generally used herein with reference to a shoe mounted on a last. The invention is herein illustrated as embodied in a `shoe support that is part of a machine for leveling the bottoms of shoes progressively, but it is to be understood that it is not thus limited in its applicability.

A feature of the invention consists in novel `means for supporting a shoe at the top of the forepart, so constructed as to adjust itself readily to the contour of each shoe and thus to insure that each shoe will be eiiectively supported against pressure applied on its bottom face without danger of damage to the upper through excessive pressure of the supporting means thereon in any location. For the purpose in View the construction shown comprises a iorepart-supporting device or toe rest movable about an axis extending laterally of the shoe and located substantially at its shoe-engaging face to minimize any tendency for the device to rub on the upper in its adjustment to the contour of the shoe, the device being supported on roller bearings to permit it to adjust itself readily to the shoe in response to pressure of the shoe thereon. Combined with this fo-repart-supporting device, in the construction herein shown, is a heel-end support comprising a member so mounted as to adjust itself readily to the top face of the cone of the last to assist in insuring against breakage of the last when heavy pressure is applied on the shoe bottom; but it is to be understood that in its more general aspects the invention is not limited to this particular combination.

The novel features of the invention will now be more particularly described by reference to the accompanying drawing and pointed out in the claims.

In the drawing,

Fig. 1 is a view in side elevation of a po-rtion of a machine in which the invention is embodied, parts being broken away to illustrate the construction more clearly;

ine II--II of Fig.

Fig. 2 is a section on the l 1; and

Fig. 3 is a section on the line III-III of Fig. 1.

The invention is herein illustrated as applied fto a leveling machine of a well-known type, characteristic features of which are illustrated and described in various prior United States Letters Patent, including Letters Patent No. 1,667,761,

granted on May 1, 1928 upon an application of E. Winkley and H. A. Davenport. Such machines include in the port or jack comprisi post 12 carrying me last are supported io formed by a roll 13 sure on the sole and ir organization a shoe supng a heel post l0 and a toe ans whereby the shoe and r the leveling operation perthat applies downward presacts progressively along the shoe ybottom as the jack is swung in directions lengthwise of the shoe. The heel post 10 carries a spindle 14 which enters the spindle hole in the n heel end of the last, the spindle being mounted on a block 16 pivoted at 18 on an upward extension of the heel post to swing in directions lengthwise of the shoe. The block 16 is connected by a link 20 to mechanism (not shown) ,Y l whereby the block and spindle may be swung to press the toe end of the shoe firmly down upon toe-supporting means on the toe post l2, as more fully disclosed in Letters Patent No. 1,719,158, granted on July 2, 1929 upon an application of E. E. Winkley and H. A. Davenport. This toesupporting means is in many respects similar to the disclosure of Letters Patent No. 1,171,383, granted on February 8, 1916 upon an application of W. C. Baxter, and comprises a member 22 adjustable on arcuate guideways on the toe post 12 by means of a worm 24, this member having mounted thereon a block 26 adjustable upwardly or downwardly by means of a wedge 28. Supported on the block 26 is a toe-supporting device or toe rest 30 comprising a rubber pad 32 hollowed 85 out to receive the toe of the shoe and a holder 34 on which the pad is mounted.

For purposes of this invention the toe rest 30 in the construction shown is so mounted on the block 26 as to permit it to adjust itself to each 90 shoe about an axis extending laterally of the shoe and located substantially at the shoe-engaging face of the pad 32. To this end, the block 26 has an upper face 36 curved about such an axis to provide an arcuate guideway, and the holder 34 has alsimilarly curved lower face 38 which rests upon roller bearings supported on the face 36. The roller bearings comprise rolls 40 `mounted at theirends in curved plates 42 whichhold 4 them in assembled relation and move with them along'the guideway-B. The holder 34 has laterally projecting anges 44 which are overlapped by flanges formed on retaining plates 46 that are fastened to the block 26 By this means the toe H rest 30 is held in place on the roller bearings 1651 while permitted to turn freely about an axis located substantially at the upper-engaging face of the pad 32 to adjust itself to each shoe without any substantial displacement of its upper-engaging face lengthwise of the shoe and thereforeulo' without any substantial rubbing action on the upper. An effective support is thus provided for the toe end of the shoe over an extended area without danger of excessive pressure on the upper in any location, the pressure being substantially uniform on all portions of the upper engaged by the pad 32. To limit the movement of the toe rest in one direction when there is no shoe in the machine there is provided on one of the plates 46 a screw 48 the inner end of which is arranged to engage a shoulder 50 on one of the flanges 44.

Further to assist in supporting the shoe and last iirmly against pressure applied on the bottom of the shoe, there is mounted on the block 16 for engagement with the top face of the cone of the last a plate 52 provided at its opposite sides with dov/nturned flanges 54 having arcuate lower edges supported on similarly curved shoulders of the block 16, the plate being provided with an opening 56 considerably larger than the spindle 14 and through which the spindle extends. rIhe plate 52 is accordingly free to tip about an axis extending laterally of the shoe to adjust itself to the top face of each last and thus to provide a firm support for the last both forwardly and rearwardly of the spindle, this axis, as shown, being located substantially at the top of the cone of the last. To retain the plate 52 in proper position its iianges 54 are provided with pins 58 which extend into curved slots 60 in portions of the block 16 that are adjacent to the iianges.

While there are herein disclosed, as above described, supporting devices that are self adjusting at both the toe and heel ends of the last and shoe, it will be understood, as hereinbefore suggested, that the invention is not limited to such devices in combination; nor is it limited to a forepart-supporting device movable about an axis located precisely as described. It is also to be understood that the invention is generally applicable to machines for performing various operations on shoes.

I-Iaving described my invention, what I claim as new and desire to secure by Letters Patent of the United States isz- 1.
