BALLABD, oF BEVERLY, MASSACHUSETTS, ASSIGNOR 'ro UNITED SHOE- raacrrmnnr ooaroRa'r-rorr, or ra'rnnson, NEW JERSEY, A CORPORATION 03 NEW JERSEY HEEL-SEAT FITTING DIACHINE Application filed February 25, 1927, Serial No. 170,881, and in Great Britain April 17,1926.

This invention relates to machines for use in the manufacture of shoes and is illustrated as embodied in a heel-seat fitting machine adapted to trim the heel-seat portions of the soles of shoes for the attachment ofwood heels.

A heel-seat fitting machine of a type which is used extensively for fitting the heel-seat portions of the soles of shoes for the attachment of wood heels is disclosed and claimed in United States Letters Patent No. 1,661,391 granted on March 6, 1928 on the application of William C. Stewart. Machines of this type are provided with a work support arranged to receive a last upon which is a shoe, the work support being movable to present the shoe to a pair of crease plates the edges of which are formed and arranged to enter the rand crease of the shoe to be operated on. Preferably, and as illustrated in said application, these crease plates are mounted for pivotal movement about a point substantially in line with the back seam of a shoe upon the support, the forward portions of the crease plates thus movingtransversely of the forward portion of the heel-seat of the shoe. A trimming cutter is mounted for movement peripherally of the heel-seat of the shoe, being guided by a horseshoe-shaped slot part of which is formed in each of two plates relatively adjustable so that the spread of the horseshoeshaped slot and of the path of movement of the trimming cutter may be varied to adapt the machine to operate upon differentsizes of shoes.

It is an object of the present invention to improve machines of this character in a manner which will result in diminishing the labor and attention required of the operator, thus increasing the output and reducing the possibility of trimming heel-seats to wrong dimensions. With this in view a feature of the invention comprises an arrangement by which the path of movement of the cutter during the trimming operation is determined by a dimension of the shoe being operated upon thereby eliminating the neces sity of a manualadjustment in passing from a shoe of one size to a shoe of another. In the illustrated machine the spread of the horseshoe-shaped guide which controls the path of the trimming cutter-is determined by the position of the crease plates-which enter the rand crease of the shoe, so that the width to which the heel-seat of the sole of the shoe is trimmed is dependent upon and is automatically determined by the width of the shoe itself. 1 I

In using machines of the type disclosed in said United States Letters Patent No. 1,661,391, it is necessary to adjust the height of the Work support so as to compensate for variations in the heights of theditl'erent lasts which carry the shoes presented to the ma chine. It is necessary that each shoe be supported during the trimming operation with the edges of the crease plates of the machine in its rand crease and that the shoe-be supported with the upper leather at the periphery of its heel-seat pressed firmly against the under surface of the crease plates.

It-is a further object of the presentinvention to provide a work supporting means applicable to machines of this type arranged to press the shoe upwardly against the edges of the crease plates with a pressure which is substantially uniform irrespective of variations in the heights of the different lasts on which the shoes to be operated upon are mounted, and this without the necessity of manual adjustment of the height of the work support and, indeed, without requiring the attention of the operator. In the illustrated machine the work support is made up of a pair of telescopic members. The-member which carries the shoe to be operated on is urged upwardly by a light spring arranged to yield as the operator moves the shoe into position between the" crease plates. This work supporting member is so connected to the crease plates that it is forced upwardly when the crease plates are moved to cause their edges to enter the rand crease of the shoe to be operated upon an amount determined by the position of the crease plates, thereby causing the shoe to be pressed against the under surfaces of the crease plates with a pressure substantially uniform irrespective of variations in the heights of difierent lasts. The height of the work support, when brought to position in the rand crease of the shoe, is thereby related inversely to the width of the shoe. Accordingly, since the variations in the heights of lasts of differentsizes are approximately proportional to the variations in their widths, the position at which the work support is held during the operation of the machine is inversely related to the height of the last upon which the shoe is mounted andthe shoe is thus supported with its rand crease in the plane of the edges of the crease plates and is forced upwardlyagainst the crease plates with a pressure substantially uniform irrespective of variations in the heights ,of different lasts. As illustrated, a cam segment is pivoted adjacent to the worksupport and bears upon a roll carriedithereby so that, as the cam is rocked, the worksupport will be raised. In order, however, ato compensate for' minor variations in the relation of the heightsto the widths of lasts, the connections between the work support and-theorease plates are preferably impositive and, as. illustrated, include a link pivoted to the cam and having a pin-and slot connection to a lever which rocks as the creaseplates are'moved. A spring tending tour-gs 'the'pin toward one end of the slot is 30 arranged -to yield when the shoe carried by the last .upon .the work support is pressed upwardly against the under surface of the crease'plates with the desired pressure.

WVhile the invention is disclosed herein withtrespecttoa heel-seat fitting machine of the type disclosed in said United States Letters Patent No. 1,661,391, it, should be understood that this is merely an illustration of one of its uses, since evidently in various of its aspects it may be embodied in machines of other types.

lVith the above and other objects and features in'view, the invention will now be described in connection with the accompanying drawings and pointed out in the claims.

Since machines of that type are well 'known and since the present invention relates particularly to improvements in the means for controlling the path of movement of the cutter used to trim surplus material from-the peripheral portion of the heel-seat of the shoe and to means for controlling the work as it is presented to'the machine and operated on,

it has been consideredunnecessary to describe or illustrate certain other parts of the machine. For-a, disclosure of such parts, refer ence may be had to .the. application referred to.

The illustrated machine is provided with a pair of crease plates 10 having thin edges 12, adapted to enter the rand crease of a shoe as shown inFig. 3. The rand crease entering-edges 12 of-crease plates 10 ha-veanapproximately horseshoe-shaped or U-shaped contour, fbeing pivotally adjustable about a point, indicated ,at 11 in Fig. 2, substantially in line with the back seam of a shoe the rand crease-of which is being or has been entered by the edges 12 of. the crease plates. To

permit this pivotal adjustment, the crease plates 10. Table 120 as-shOWn in Fig. l is carried by the bedaplate 24 of the machine, the bed-plate being supported in any suitable "Way :as by. a frame or legs 26.

To adjust crease plates 1O about their center 11, a hand lever .32 is pivoted at (,Fig'. 2-) :to the frame of the machine. Lever 32'ha's an upwardly extending arm 34, connectedbya link' 36 with a lever 38 fulcrumed atAO tothe 'frameof the machine. A pair of links *4i2 pivoted .at l lto lever 38 extend forwardly and are pivoted at 46 to the respective crease plates 10. Thus, as hand lever 32 is rocked-downwardly, crease plates 10 will be moved pivotal ly in such-a manner thattheir forward extremities, which are opposite the forward portion of the heel-seat of a :shoe presented thereto, move toward each other transversely of the shoe, edges '12 of the crease plates .entering the rand crease of the shoe and being positioned thereby in To lever 32 isprovided with a group of pawls 48-co-operat-ing with a ratchet 50 secured to the rfiraaneof the machine. Pawls 48 1nay be released itromzratchet:50-by'1neans of a supplemental lever :52, pivoted at 54*:tolever-32 and controlling pawls 48 in a well-known fashion.

The machine is provided with a rotating cutter carried by a shaft 62 to the upper end of which is secured the rotor of a motor 64 carried by a horizontally swinging lever 66. Lever 66 is fulcrumed at 68 to a second lever 70 which latter is fulcrumed at 7 2 to u, sliding table 74 carried in ways 7 5 secured to the frame of the machine. These parts may be constructed and operated as in the above referred to Patent No. 1,661,391.

To control the path of movement of cutter 60, the machine is provided with a. pair of plates 80, secured by screws 84to a pair of arcuate plates 86, supported by sliding table 74 and mounted for rotary movement about their center of curvature which, during the operation of the machine, is positioned vertically above the center with respect to which crease plates 10 are pivotally adjustable. To this end, plates 86 are provided adjacent to their edges with a groove 88 surrounded by a rim 90 engaging a supplemental rim and groove formed in a plate. 92 secured by screws 93 to sliding table 74. Adjacent portions of plates 80 are reduced in thickness and overlap as indicated at in Fig. 2. As illustrated, table 74 is made up of two parallel plates, the lower of which is indicated at 94 (Fig. 4), the two plates being separated so as to receive a disk 96 which serves as a support for a bushing 98 which receives cutter shaft 62.

Formed in plates 80 is a substantially horseshoe-shaped slot 104, which receives and determines the path of movement of cutter shaft 62, thus determining also the form or shape of the path of movement of cutter 60 as it is moved by levers 66 and 70 during the trimming operation. In order to vary the path of movement of cutter 66 in accordance with the width of the shoe to be operated upon, plates 80 and 86 are connected to crease plates 10 so that they are adjusted and the spread of slot 104 varied in accordance with the position of crease plates 10. Thus plates 86 are connected by links 106 to a lever 108 fulcrumed at 110 to sliding table 74. A

spring 112 connected at one end to lever 108 and at the other end to plate 92 tends to rock lever 108 in a clockwise direction as viewed in Fig. 2, thus tending to move plates 80 toward the position which they occupy when the machine is operating upon a shoe having a heel-seat of minimum width. Depending from lever 108 is an arm 114, carrying an adjustable stop illustrated as a screw 116211- ranged, as sliding table 74 is moved forward preparatory to operating upon a shoe,

to engage an upstanding arm 118 carried by lever 38. Thus as table 74 is moved forwardly by the depression of hand lever 121 from the rearward position which it occupies while a shoe is being presented to the machine, arm 114 strikes arm- 118, and since the position of arm 118 has been determined by the position of the edges of crease plates 10, which at that time are positioned in the rand crease of the shoe tobe operated upon, lever 108 will berocked in a countenclockwise directi on to an extent dependent upon thewidth of the shoe to be operated upon and the spread of horseshoe-shaped slot 104 willbe adjusted in accordance with the width of the heel-seat of that shoe as measured by crease plates 10. To assist crease plates 10 in supporting the shoe to be operated upon, the machine is provided with a work support 120 which includes, as illustrated, a hollow sleeve 122 hava last pin 124 at its upper end to receive the last 126 upon which the shoe to be operated upon is mounted.

Sleeve 122 is telescopically carried by a post 128. A light spring 130 engaging at its upper end against sleeve 122'and at its lower end against post 128 and being prevented from displacement laterally by a rod 132,

tends to lift sleeve 122 and the last carried f thereby with a light pressure which can be easily overcomeby the operator as he positions the shoe manually relatively to the crease, plates. Post 128 is pivoted at 134 to a cross-bar 135 forming part of the frame of the machine. Eigidly connected to post 128 are a pair of cams 136, the upper surfaces of which are arranged for engagement with a pair of rolls 138 carried by sleeve 122. Pivoted to one of the cams 136 is a link 140 formed toward its rear end with a slot 142 which receives a pin 144 carried by a downwardly extending arm 146 of lever 32. A moderately still" spring 148 is connected at one end to pin 144 and at the other end to the forward extremity of link 140 and tends to move link'140 rearwardly so that pin'144 engages the forward end of slot 142. When the crease plates 10 are moved to cause their thin edges 12 to enter the rand crease of a shoe, arm 146 of lever 32 moves rearwardly and through spring 148 rocks cams 138 in a counterclockwise direction as viewed'in Fig. 2. Thus by the engagement of cams 136 with rolls 138, the sleeve 122, last pin124 and the last carried thereby, are moved upwardly until the inturned edge of the'counter portion of the shoe upper is pressed firmly against the lower surfaces of the edges 12 of crease plates 10. Excessive pressure of the shoe against the lower surface of the edges 12 of crease plates 10 is, however, avoided by the stretching of spring 148, pin 144 at that time moving rearwardly in slot 142. In order to urge the shoe rearwardly relatively to crease plates 10, the shape of cams 136 is such that toward the end of their rearward movement they tend also to force sleeve 128 of the work support, 122 rearwardly. 1

The illustrated machine, like that disclosed its in .Patent No. 1,661,391, is provided with a knife 150 arranged to make a heel breast receiving cut transversely of the sole of the shoe operated upon, the knife 150 being carried by a transversely movable bar 152 operated by a suitable treadle mechanism 154, 156. Also a stop 158 may be provided to limit the forward movement of cutter and suitable index mechanism 160 provided adjusta bly :to position the stop 158 and the knife carrying bar 152. A stop 162 limits the forward movement of table 74:.

The mode of operation of the machine will beapparent from the foregoing; however, it should be noted that the construction described is such as to cause the width of the heel-seat of the shoe operated upon to determine automatically the spread of the path of movement of the trimming cutter. The width of the heel-seat of the shoe operated upon is also utilized to determine the height at which the work support is positioned during the trimming of the heel-seat, the height of the work support being varied, however, in inverse relationto the width of the shoe. Since the heights oflasts of different sizes butof the same style vary directly as their widths, this variation in height of the work support in inverse relation to the width of the lasts serves to compensate for variations in the heights of the lasts. The pin and slot connections 142, 144 and the spring 148, on the other hand, serve to compensate for differences in the ratio of the width to the height oflasts of difierentstyles and thus make it unnecessary for the operator to pay any attention to adjusting the height of the work support. Similarly, the positioning ofplates and the control of the spread of thehorseshoe-shaped guide slot 104 by the position of the crease plates 10 and the adjusting means therefor serve automatically to control the path'of the trimming tool in accordance with the width of the particular shoe being operated upon and this also without any attention on the part'of the operator.

- Looking at the operation of the machine froma somewhat different viewpoint, it may also be said that variations in the width of the heel-seats of the shoes operated upon are I utilized to insure that the shoes are pressed upwardly against the under surface of the crease plates 10 with a pressure which is substantially uniform irrespective ofv the variations of thesizes of the lasts upon which different shoes are mounted.

7 The operator in presenting a shoe to the machine, places its last upon last pin 1% and moves the work support rearwardly, position .ing the shoe between crease plates 10 and cansing the edge 12 of the crease plates to enter the rear portion of the rand crease of the shoe. At thistime, spring 130 yields as may be necessary to permit the proper positioning of the shoe by the operator. Then the operator forces lever 32 downwardly, moving the creaseplat es 10 about center 11 and causing the forward portions of .the creaseplates tomove toward each other in a direction transversely of the heel-seat of the shoe so that the edges 12 of the crease plates enter the rand crease of the shoe and support the whole of the periphery of the heel-seatzportion of the sole of the shoe, from the rear to points forwardly of the heel breast line. As crease plates 10 are moved toward and into the rand crease of the shoe, cams .136 are rocked in a counter-clockwise direction as viewed in Fig. 2, and, when they engage rolls 138 carried by member 122 ofthe work support move member 122 of the work support upwardly and force the shoe against the'under surfaces of the edges of the crease plates 10. Since the extent of movementof the crease plates is determined by width of the heel-seat portion ofthe shoe to be operated upon, the movementof the cams 136 is similarly determined with the result that'the position to which the work support is brought in its upward movement is determined by the width of the shoe. Since the movement of the crease plates 10 is less when a large shoe is to be operated on andgreater when a small shoe is to be operated on, the movement of cams 136 and therefore the position to which last pin 124 is moved-is not only determined by the size of the shoe, but is inversely related thereto. Thus the pressure with which the shoe is forced against the under surfaces of the crease plates is substantially uniform irrespective of variations in the heights of the different lasts upon which the shoes are mounted.
