T0 (.171 whom it may concern:

Be it known that I, ERASTUS E. WINKLEY,

a citizen of the United States. residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Shoe Machines; and I do hereby declare the following to be a full. clear. and exact description of the invention. such as will enable others skilled in the art to -which it appertains to make and use the same.

This invention relates to machines for making boots and shoes. and it has special reference to such machines as are adapted for the production of regular and wellshaped heel ends of boots and shoes.

In the commercial manufacture of boots and shoes, it has heretofore been customary to attach a rough heel to the heel-seat portion of the outsole. after which a definitely shaped. condensed top-lift is spanked on. The rough heel and the heel seat edge of the outsole are then trimmed or shaved to their final size and form by means of a cutter. the movements of which are prescribed and determined through the agency of guide members that cooperatively engage the edge of the top-lift and crease of the heel-seat between the upper and the outsole. In this process of manufacture the ultimate appearance of the heel end of the shoe depends upon the accuracy of the position of the toplift relative to the heel seat and the size and contour of the top-lift and heel crease. The heel crease is rarely perfectly regular but is generally distorted and somewhat uneven, and is practically always affected by the back seam of the shoe. Moreover, the top-lift is very apt to be located slightly off centre.

The result of controlling the trimming operation from the top-lift and heel crease as guides, therefore, is to produce non-uniform shoes, the heel ends of which are more or less irregular, distorted and lop-sided in shape.

One of the objects of the present invention, therefore, is to overcome the difliculties Serial No. 61,842.

that have been encountered in the past, and to provide an improved, simple and inexpensive machine for producing heel ends of boots' and shoes that shall be regular, uniform, and substantially perfect in size and form when the shoes are finally finished. In accordance with the present invention, it is proposed to employ heels that, before attachment to the shoe, are made to definite, regular and final size and shape, preferably, although not necessarily, as set forth in a co-pending application Serial No. 213,681, filed by the present applicant on January 25, 1918 and renewed June 20, 1923. -These heels are accurately positioned with respect to the shoe itself and may even, if desired, be; attached to the heel-seat of the outsole, after which the unfinished heel-seat of the outsole is fitted, as by being trimmed and randed, to the definitely shaped heel as a pattern by means of a suitable cutter that is properly positioned with respect to the shaped heel by a gaging device that cooperatively engages the lateral surface of its body contiguous to the seat face of the heel. The trimmed and randed heel-seat and the heel may be. in some kinds of shoes, later scoured and finally finished together in accordance with customary practice.

Other objects of the invention and features thereof by which they are attained will be apparent from the following description of the preferred embodiment thereof.

The preferred embodiment of the invention is illustrated in the accompanying drawing, the single figure of which is a view, in side elevation, of a boot or shoe prising an unfinished outsole 12 and a heel 14 and .to -lift 16 of final size and shape, is clampe in position upon a support 20, the peripheral portion of the heel-seat 22 of the outsole 12 being trimmed by means of a rotary cutter 24 that is definitely positioned relatively to the heel endot the outsole during the trimming operation through the agency of a gage or guide 26 that cooperatively engages the heel seat portion of the lateral surface of the definitely shaped heel 14 which serves as a pattern or templet.

The shoe 10 may be of any type of construction, having a rough, unfinished outsole secured thereto. The heel 14 is preferably treated and compressed to final size and form in the manner set forth in the above mentioned co-pending application, Serial No. 213,681 and it is properly centered with respect to the shoe and attached to the heel-seat portion 22 of the outsole 12 in the ordinary manner, a top-11ft 16, also of final size and form, being spanked on or otherwise suitably positioned.

The support 20 for holding the shoe during the trimming operation constitutes a plate that is rigidly associated with a supporting post 28 and is provided with edge clamps 30, an adjustable breast guide '32 for positioning the heel, and a clamping foot 34 that is disposed within the shoe and acts to firmly clamp the shoe to the support 20. It will be understood that the illustrated clamping support is not essential as any supporting means which is adapted to position the heel-seat of the outsole intrimming relation to the cutter is within the scope of the invention.

The rotary cutter 24 is provided with a hub 35 that is rotatably mounted upon a stud 36 which is carried by a supporting arm 38, and said cutter 24 may be provided with an upper projecting cutting portion or lip 42 for bevehng or cutting the randing 44 on the upper edge of the heelseat portion 22 of the outsole 12. The

means for trimmin the periphery of the "outsole is constituted by a slightly inclined,

main cutting portion 46. The cutter 24 is of substantially the same width as the edge of the heel end of the outsole and is adapted to trim the outsole only. A pulley 48 is fixedly secured to the hub 35, and a belt 50 cooperates therewith to rotate the cutter 24 at high speed.

Beneath the cutter 24and loosely mounted upon the hub '35 above the pulley 48, is the cutter gage, in the form of a ring 26,

the periphery of which has the same in-' clination as that of the main cutting portion 46 of the cutter and extends in alinement therewith. The periphery of the gage 26 is adapted to engage the lateral surface of th definitely shaped. and formed heel 14 at the edge of the heel-seat and, thereby, to definitely position the cutter 24 and control the amount of stock removed by it during the trimming operation, to the end thatthe periphery of the heel-seat portion 22 of the outsole is trimmed, and randed if desired, to the shaped heel as a pattern. In order to protect the upper -52 of the shoe 10 from being injured during the trimming operation, a disk or shield 54 is loosely mounted above the cutter 24 upon a screw 56 which is threaded into the end of the stud 36, and the edge of this shield projects into the heel-seat crease and serves as a barrier for the intended purpose.

During the trimming operation, relative bodily movement between the shoe 10 and the cutter 24 is effected in anv suitable manner, it being within the contemplation of the invention that either or both the shoe and cutter be rotated.

By reason of trimming and randing the heel-seat portion 22 of the outsole to the contour of the definitely shaped and formed heel as a pattern. it is evident that a correspondingl-y definiteh shaped outsole, heelseat and randing will be insured. The heelseat portion 22. heel 14 and top-lift 16 in some kinds of shoes are subsequently lightly scoured and otherwise finished in accordance with well-known practice. Thus, regular, well-formed and substantially perfect heel ends are uniformly produced upon shoes that are operated upon through the agency of the means embodying the present invention.

Modifications may be made in the structure hereinbefore set forth without departing from the spirit and scope of the invention. 1
