A CORPORATION OF NEW JERSEY MACHINE FOR USE IN FORMING HEEL SEATS 0N BOOT AND SHOE SOLES Application filed April 11, 1927, Serial No. 182,676, and in Great Britain April 14, 1926. i

This invention has reference to machines for use in forming heel seats on boot and shoe soles for the reception of wood or like heels having a concave upper surface and more especially to the type of machine in which the heel end portion of the sole is deformed by a plunger and a form plate and a skiving knife is provided whereby the heel seat is in part severed from the sole, leaving,

f usually, an approximately U-shaped marginpedited; means whereby, when desired, a

shoulder extending across the surface widthwise of the sole may be produced to form an abutment for the breast edge of the heel which, additional to or instead of the shoulders or the tabs on the sides of the sole, may

be utilized to determine the position of the heel on the shoe, and in which machine the marginal portion of the sole may be held yieldingly whilst the central. portion or main part is being deformed for the purpose stated.

Further, when using machines of the type referred to as heretofore constructed for forming a heel seat 011 a shoe sole that is already stitched at the forepart and at the waist to the shoe, a practical difficulty arises due to the following:

It is not readily possible in everyday fac tory practice to start and finish the sole-sewing at the precise distance from the heel end of the shoe and so that the first and last stitches are located precisely opposite to each other on the shoe, as to leave unconnected to the shoe the exact desirable length of the heel end of the sole for presentation to the heel seat forming instrumentalities. It is therefore customary to begin the stitching at one side and to finish it on the other side of the shoe sole nearer to the heel end than is no required and for the operator who is subsequently to form the heel seat on the sole to sever by a hand knife one or more stitches on each side of the sole according to the re quirements for the purpose stated of the particular shoe about to be operated on. This not only requires considerable skill and judgment on the part of the operator and the frequent offering of the shoes to the seat forming instrumentalities to ascertain whether enough stitches have been severed, but there is the risk of his cutting too many stitches on either one or both sides and also the risk of his cutting into the leather owing to the fact that the sole is drawn by the stitches into very close contact with the marginal portion of the upper on the insole. Although attempts have been made to provide means whereby the operator mayinsure the accurate severing of the stitches for the purpose stated before the shoe is presented to the heel seat forming machine, the means have been too complicated for adoption in everyday factory practice.

A further feature therefore of our invention is the provision of means of extremely simple character whereby the severing of the stitches as aforesaid may be effected with absolute accuracy whilst the operator presents the work to the heelseat forming in strumentalities.

The above and other features of our invention will become apparent from the following description of a preferred constructional form of machine incorporating the several features of our invention.

The said preferred constructionalform of our machine is illustrated in the accompanying drawings in which Fig. 1 is a side elevation of the illustrated machine, certain severing cutters being omitted so as to expose to view a shoe in position; Fig. 2 is also a side elevation showing more in particular the severing cutters; Fig. 3 is a front elevation of the complete machine; Fig. 4 is a plan view thereof; Fig. 5 is a view on an enlarged scale of an important feature of our invention; and Figs. 6 and 7 are plan and side elevations respectively of stationary cutters for severing sole attaching stitches. y

In said drawings the numeral 6 indicates the head or frame of the illustrated machine to support the working parts, which head is carried by a standard 5. At a position convenient to the operator the head carries a horizontal form plate 8 having a U-shaped opening the upper marginal portions 9 of which are inclined to the horizontal and form a concave portion of the plate.

Arranged for movementin a vertical hearing 12 we provide a plunger 60 whichiscarried on a stem 61 and by movement of which plunger in the vertical direction downwardly the central part of the heel end of a sole placed on the form plate 8 will be bulged throughtheopening therein, and the bulgedthrough portion may be in part severed from the sole by a: skiving knife 26 arranged for movement below the plate 8 in suitable guideways. 1' Y Surrounding the vertical spindle 61 we provide a sleeve64 the lowerend 'of which sleeve carries presser feet 66, 68, having inclined lower faces 70, 72, respectively, the inclination of said plates being similar to that of the marginal inclined faces 9 of the form plate 8. Interposed between the sleeve 64 and a collar 62 on the spindle 61 is a spring 7 6 that tends to press the presser feet 66, 68, downwards towards the inclined faces 9 of the form plate, the downward movement of said presser feet being limited by a shoulder 69 on the sleeve 64 engaging against the forwardly projecting part of the plunger 60. While the term plunger has been appliedto the portion of the machine identified by reference numeral 60, itwill'beclear that the presser feet 66, 68, together with the plunger 60, serve to distort the sole and may be considered jointly as a plunger.

Arranged for movement in the plane of the 'skiving knife .26 in the direction transversely of the machine we provide cutters such for example as 50 which are arranged for movement from the opposite sides of the machine towards the centre and are intended for J: severing the marginal portion from the shoe sole;

The foregoing ate as follows I When the heel end of a shoe sole has been arts are arran ed to 0 erv i b placed on the form plate 8 the operator by depressing a treadle will depress the plunger 60 and with the plunger will move the presser feet 66, 68. The plunger and pressers will move until the pressers firmly hold the marginal portions of-the sole against the inclined In this position the pressers 66, 68, will very firmly hold the marginal portion of the sole against the inclined faces so that they cannot become displaced when thesevering cutters 50 are actuated.

m- Foroperating the plunger 60 and pressers 66, 68, we provide a treadle lever (not shown) that we connect by a rod let to one end of a rocking lever 15 carried on the pivot pin 16 in the upper part of the frame or head. The forward end of said rocking lever is con nected by a link 18 to the rear end of a second rocking lever 19 which is supported for rocking movement on a pivot pin 20, the forward endof which rocking lever19 has a rounded head 21that engages against the upper end of the spindle 61 and by which the plunger and presser feet'may be actuated .as already described. The plunger 60 is normally held raised'some distance above-the form plate 8 by a spring 13 and may be lowered by depression of the rod 14.

We provide an adjustable stop pin 22 on the rocking lever 15'to engage against a block 23'on the head of'the machine, by'which stop the extent of downward movement of the plunger may be limited as may be desirable according to the thickness of the shoe sole to be operated on.

For the purposeof operating the severing cutters 50 we provide the following 1neans:-

Secured to the front of the head 6' we provide two brackets 30, 31, one on each side of the form plate 8 and of the plunger. Each bracket is provided with an arcuate slot 32 through which projects a bolt 33 that carries a bearing 34'for a sleeve-like member '35. The bearing 34 is adapted to be.

clamped by a clamping screw 37 so-as'fir mly to grip the member 35. Passing through the member is a spindle 39 which at its outer end is pivotally secured to a lever 42 which is at its rear end'connected by a link 43 to the machine head and at its front end is provided with a handle-l5. Secured to the spindle 39 by its shank48 is a severing cutter 50 the lower extremityof the cutting edge of which is in the plane (substantially) of the upper face of the skiving knife and the shank 48 engages in a slot in the sleeve member 35 so that the spindle 39 and severing cutter 50 are adapted to be moved in the direction axially of the spindle; By adjusting the position of the sleeve like member 35 about its axis the angular position of the severing. cutter may be set so that when the handle lever 42 is actuated the severing cutter 50 will sever the leg on one si'deof the U-shaped trimming '(of course the corresponding cutter 50 on the other side will be instrumental in severing the other'leg). If there is adhering a thin layer or flap it will be merely necessary to move the severing cutters 5 0 until they reach the longitudinal median line of the sole when the said flap and the legs of the U-shaped marginal portion will both or all have been severed so to be completely detached from the sole. If there is no flap as aforesaid left attached to the sole, on the completion of the severing cuts by the cutters 50 the sole will merely have a shoulder at each side. If however a thin flap was left adhering to the upper face of the sole then, when the cutters 50 have been operated, they will not only form shoulders on each side but a shallow one across the face of the sole also. lVhether the shoulders will be undercut or not depends upon the adjustment of the parts as already described. It has been pointed out that some heels have a concave breast face (viewed in plan) and therefore it is desirable to cut the shoulders not at right angles to the longitudinal median line of the sole (which would be suitablefor heels having a fiat breast face) but at some less angle according to the shape of the heels to be attached to the shoes and for this purpose the operator will slacken back the screw and adjust the bearing along the arcuate slot and again clamp the parts in adjusted position.

In order to insure accurate positioning of the shoe there are provided two gauges 53, 5-1, against which the heel end of the shoe is engaged. The former of these engages the heel end so as to determine the position thereof laterally and the other, 54, to determine the position longitudinally of the shoe. The gauge 53 is yieldingly supported so that the workman when he has engaged the heel end of the shoe therein can push this back until the shoe engages against the gauge 54. There is preferably also a gauge 56 against which the operator holds the forepart of the shoe and this gauge is carried on a pivot 57 on lugs 58 so that the operator may lift the gauge and swing it out of the way if and when he does not require to use it. All the gauges are adjustable.

Secured to the form plate and having their longitudinal median line in substantial align ment with the outer edge of the tapering marginal portion of the form plate, we socure stitch severing cutters 80, the upper surfaces of which may be flush with the underside of the form plate and the lower frontparts of which are chamfered off. The cutters may be adjustable either in the plane of or in the plane perpendicular to the under face of the form plate and their cutting edges may be in alignment or at an angle to each other. They may also be adapted for adjustment forwardly and backwardljy of the plate so that they may be adjusted to suit different sizes of shoes. They will be made wide enough so that they will serve the purpose described for several sizes of shoes without requiring adjustment. Although the severing cutters are illustrated as being clamped to the form plate in order to effect the above-mentioned adjustment, it is clear that these cutters may if desired be formed integral with the form plate and hay constitute parts thereof.
