UNITED STATES PATENT oFFio ORB/ELL ASHTON, OF SWAMPSGOTT, MASSACHUSETTS, ASSIGNOR T0 UNITED SHOE MACHINERY COMPANY, OF EATER-SON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

Application filed April 9, 1915. Serial No. 20,213.

To all whom it may concern:

Be it known that I, ORRELL AsH'roN, a citizen of the United States, residing at Swampscott, in the county of Essex and State of Massachusetts, have invented certain Improvements in Shoe Shaping Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in theseveral figures.

This invention relates to machines for use in shaping shoes and is herein shown as embodied in mechanism which is particularly useful for shaping turn shoes although not necessarily restricted to use upon shoes of this particular type.

In the manufacture of turn shoes, in which the upper is sewed directly to the single sole while the parts are inside out and the shoe is then turned and relasted, both the upper and the sole after relasting are found to be in a more or less wrinkled and distorted condition. This is particularly noticeable at the sides of the upper and at the projecting edge portion of the sole and on the bottom of the sole over the line of sole attaching stitches. It is necessary, therefore, after the relasting of the shoe, to conform the upper to the last and'to shape the sole. The operation of shaping the up per is usually efiected by the use of means engaging the side of the shoe from the welt crease upwardly and operated to beat or rub the upper to conform it to the shape of the last. Because of the relatively thin and yieldingcharacter of the sole of a turn shoe and the fact that at this stage in the manufacture of the shoe the sole is in a' damp and pliable condition, it is important during the operation of shapingthe upper to guard against ben'ding'the projecting edge portion of the sole downwardly away from the upper and opening the welt crease in such manner as to show the sole attaching stitches; and because of the above-mentioned character and condition of the sole it has been found advantageous, also in shaping the projecting edge portion to operate upon both sides of the sole simultaneously.

An important object ofthis invention accordingly is to provide improved mechanism Specification of Letters Patent.

SHOE-SHAPING MACHINE.

Patented Mar. 14, 1916.

for use in shaping the upper and portions the invention consists in a novel combination and arrangement of means for engaging and beating the side of a shoe from the welt crease upwardly and means for supporting the projecting edge portion of the sole during the beating operation. As herein shown this organization comprises a beating tool shaped for engagement with the side of a shoe from the welt crease upwardly, means for impartin substantially right line movements to the tool in parallel relation to the plane of the sole to causethe tool to beat the shoe, and a support arranged for continuous engagement with the bottom face of the projecting edge portion of the sole to preserve the contour of the shoe bottom during the beating operation.

A further feature of the invention consists ina novel arrangement of mechanism for shaping the projecting edge-portion of the sole of a shoefcomprislng, in the preferred embodiment illustrated, a pair of tools arranged to press yieldingly upon opposite faces of the edge portion of the sole and suitably operated to cause them to rub said faces inwardly substantially at right angles to the sole edge. As herein shown and described the 'means for rubbing the upper face of the projecting portion of the sole is a portion of a beating tool which is shaped for engagement with the upper from the welt crease upwardly, and the tool for rubbing the lower face of the sole is suitably extended to engage that portion of the sole in which the sole attaching stitches are located andis arranged also to support the edge portion of the sole during the beating and rubbing operations. 7

The above and other features of the invention, including certain details of construction and combinations of parts,will now be described with reference to the accompanying drawings and pointed out in the claims. 7 V

In the drawings, Figure 1 is an end view r of mechanism emb dy ng a pref rred form chine which includes other shoe treating instrumentalities.

The illustrated mechanism includes features of a shoe shaping device which is described and claimed in my prior application for Letters Patent, Serial No. 806,325, filed Dec. 12, 1915, and the invention presents, in one aspect, an improvement in the construction of the prior device. It will be apparent, however, from a consideration of the following detailed description that although there are practical advantages in this construction and arrangement, the present invention in many of its features is not limited to this particular embodiment.

The operating means for the shoe treating tools comprises a tool carrier in the form of lever 2 which is pivoted at 4 and. is oscillated through the engagement with its arm 6 of a cam 8 on a shaft 10 driven, in the arrangement shown, by a belt 12. The lever 2 serves not only as a carrier for tools which are formed, as will be subsequently described, for shaping the sides of the upper and the projecting edge portion of the sole of a shoe, but in the construction shown is formed also with a beating face 14 for use in shaping the bottom of the sole at the shank. The lever is maintained normally, by means of a spring pressed plunger 16, in an idle or inoperative position. with its arm 6 outside the path of movement of the the cam 8, and the lever is moved into position to be operated by the cam through pres sure of a shoe against one or another of the shoe treating tools. At the sides of that portion of the lever upon which the face 14 is formed. are shoe supports 18 upon which to position the sole of the shoe so as to prevent the shoe from pressing the tool to the limit of backward movement which would be permitted by the operating means and thus insure a sudden positive pressure of the tool upon the solewhen the cam 8 comes into engagement with the lever. Since a greater range of movement of the lever is desirable for shaping the shank portion of the sole than for treating other portions of the shoe, the machine is provided with a pivoted stop-20 which may be turned into the dotted line position to permit a relatively wide range of oscillation of the lever when the shank beating face 14 is'to be used and has a shoulder 22 which, as illustrated,

limits the backward movement of the lever when other tools are 1n use so as to prevent the lever from being moved so far by the cam. 8. A spring stop 24 engagingin notches formed in the member 20 serves to retain said member in either position of ad ustment. For limitmg the forward throw of the lever and avolding danger of breakage of the arm Gwhen a shoe is sud-- denly removed from a tool, the machine is provided with a spring held stop26.

The parts thus far specifically described are constructed in substantially the same .manner as in the device of my prior application previously referred to and require nofurther description.

In the illustrated construction the lever 2 is formed with a rounded shank portion 28 upon which is mounted, beyond the ends of the shoe supports 18, a tool head 30. Se--' cured upon one side of this head is a beating too]. 32 shaped for engagementwith the side of a shoe from the welt crease upwardly in the shank portion of the shoe. The head, on the opposite side, has flanges 34upon which is slidably mounted a tool 36 shaped for engagement with the side of a shoe from the welt crease upwardly at the forepart and having an end surface 38 formed for engagement with the upper facelof the projecting edge portion of the sole of the shoe during the beating of theupper. The head.

30 is formed also to provide a tool 40 which projects over the tool 36 and has a face 0p-v posite to the face 38 of the latter tool for.

engagement with the bottom of the shoe sole. The tool head 30 may be turned about end of this spring and the head 30 is a plate. 46. which is loosely mounted on the shank 28 so as to permit it to tip with reference to the shank and is extended to engage under the lower end of the tool 36, the plate having lugs 48 for maintaining it in proper relation to the head. The tool 36 is thus maintained normally, by means of the spring 44 I and the plate 46,'in such a position. that the opposite faces of the tools 36 and 40 are separated a distance less than the thickness of a shoe sole, the face on the tool 40 being curved as shown to permit the sole to be readily inserted between the tools in the po sition illustrated in Fig. 1. When the sole is in this position the plate 46 is slightly.

tipped, as shown, in opposition to the force of the spring 44, and the-tools 36 and '40.

are thus caused to engage the opposite faces 1 of the sole with yielding pressure. The tool 40, as shown in Fig. v1, is suitably extended 5 to engage that portion of the sole in which the sole attaching stitches are located.

amaze:

1 1 the operation of the device for treating the upper and the projecting edge portion ofthe sole of a shoe, the stop 20 will be positioned as shown to limit the extent of oscillation of the lever, and with a shoe presented as illustrated and pressed against the tool to bring the lever into position to be operated by the cam S, the tool 36 will beat and shape the upper in and adjacent to the welt crease and at the same time will rub the upper face of the projecting edge portion of the sole. The tool 40 also will rub in a similar manner the lower face of the sole transversely of'the line of sole attaching stitches and will smooth down that portion of the sole in which the stitches are located and cooperate with the tool 36 to straighten and shape the sole at theedge. The pressure of the spring 44 serves to maintain both tools in effectiverubbing'em gagement with the sole. Either of the tools 36 or 40 serves, itwill be observed, as a support for the sole during its treatment by the other tool. In connection with the beating operation of the tool 36 the tool 40 thus,

has an important function in preventing the edge of the sole from being bent downwardly away from the upper in such'manner as to strain the stitches. In view of the relatively small range of movement of the lever 2 and the distance of the tools from' the fulcrum point, it will be apparent that substantially right line movements areim If it is desired to beat parted to the tools. the upper of a shoe in the shank portion, the tool head 30 may be moved downward on the member 28 to free the pin-4C2 from the slot in the head, and then turned half way around to bring the tool 82 at the front of the device, the pin 42- again cooperating with the slot to retain the head in this po-.

sition. If the sole is to be beaten at the shank the stop 20 will be turned down into the dotted line position and the shoe pressed against the face 14 of the lever and against the supports 18 in the manner more fully explained in'my prior application to which reference has been made; 7

It should be understoodthat the expres sion edge portion of the sole as used herein comprehends whatever'materials are included between the upper and lower faces of the margin of the bottom of a turn shoe or shoe of other type in the manufacture of which the machine may be used, and that the term welt crease refers generically to j the crease between the upper of a shoe and the projecting portion of the shoe bottom.
