This invention relates tothe manufact-ure of shoes and is ldisclosed in connection with a heel seat litt-ing machine arranged to trim the peripheral portions of the heel seatsof shoes to which wood'heels are subsequently to be attached.

In themanufacture of shoes to which wood heels are to be attached, itv is usual, prior to the attachment of the heels, lto trim away surplus material from about the periphery of the heel seat of the sole of each slice, leaving the heel seat in Vcondition and of a shape to fit the concaved attaching surface of the Wood heel. This operation, which is commonly spoken of as heel seatfitting,liasbeen performed for the most part by hand. The workman first applies a wood heel to the sole of the shoe to which it is to be attached and marks the location of the breast of the heel cn the sole, then with a knife he cuts into the sole at the position of the breast corners and trims olil the surplus material to the rear of the breast corners, beveling the edge of the sole so that it approximates the concavity of the heel seat of the wood heel.v To perform this operation properly takes some degree of skill and considerable care. On the other hand, since this work is ordinarily paid for at a piece rate, the tendency of the workers is to save time at the expense of quality by trimming off an excess of material. In view of these and other considerations it is an object of this invention to improve the quality of the work and to reduce the time spent in performing this operation.

In its method aspect, this invention c0mprises a method of heel seat fitting in which buckling of the sole during thetrimming operation is prevented by performing the trimming while the sole is under tension. As eX einplified herein, the shoe is presented to a cutting tool so as to bring the heel breast line of the sole of the shoe into engagement with the cutting edge of the tool, after which relative movement of the shoe and the cutting tool trims the surplus stock simultaneously from the two sides and finally from the rear portion of the heel seat of the sole of the shoe. Thus as exemplified herein the cutting tool itself tensions the sole as it cuts.

It is a further object of the invention to provide a Yheel seat fitting machine which will be simple in construction, accurate and reliable in operation, and which can be operated effectively by unskilled help.

With this in view the illustrated machine is so organized that its trimming tool is arranged to move relatively to the sole of a shoe from the heel breast line rearwardly so that the resistance of the sole to the cutting edge of the tool tends to keep the sole tensioned as the entire cut is made. As already set forth, when the operation lis performed in this manner, the possibility of the sole buckling in front of the cutting edge of the tool is obviated. As the shoe to be operated upon and the trimming tool arev relatively positioned prior to the trimming of the sole with the cutting edge of the tool at the heel breast line of the sole, this insures that the forward extent of the trimmed or litted heel seat will coincide with 4the breast of the heel which is to be applied to the shoe. Conveniently and as illustrated, the breast cuts ai'e made prior to the performing of this stock removing' operation, the trimming cutter being placed iii and starting its operation at these breast cuts.

A further feature of the invention coniprlses a novel arrangement by which cuttingl means, illustrated as a pair of knives moving transversely of the sole, make the breast cuts at the forward extremity ofthe fitted heel seat portion, the cutting means being war-v ranged for movement either normally to oi' at an inclination to the edge of the sole so that they may be adjusted to shape the breast cut to the type of heel which is to be attached. Thus, if a Louis heel having an overhanging breast is to be attached to a shoe, these knives will move in a path'substantially normal to the edge of the sole, while if a Cuban heel is to be attached, they will enter the sole obliquely, their path 0f movement having a component rearwardly as well as transversely of the sole, and in either caseV will forni abutments adjacent to the heelvbreast line designed to co-operate with the corresponding portion of a heel to be attached to the shoe.

`With the above and other objects and features in view, the invention will now be described in connection with the accompanying drawings which illustrate a heel seat tittin machine constructed to operate in accor noe with thepresent invention.

Shaft 22 carries a worm 28 driving a worm wheel 30 mounted on a cam shaft 32. Cam shaft 32 carries a series of cams operating a series of bell crank levers mounted on a transverse shaft 34, as well as a cam for stopping the machine at the end of, each revolution of the cam shaft 32.

Shoes which are to be fitted by the machine are supported by a pair of jaws 36 (Figs. 2 and 3) each of which consists of a suitably shaped block of rubber or other yielding material mounted in an angularly adjustablecarrier 38 which is attached to a sliding rod 40. Rods 40 are formed each with a reduced portion which is surrounded by Va coil spring 42 and each rod with its spring is enclosed in a cylindrical casing 44, the .spring bein held under compression by a threaded bushing 46 formed with a central hole through which rod 40 may slide. By this arrangement, movement of casings 44 to- Ward each other operates through springs 42 yieldingly to advance rods 40 and therefore jaws 36. This arrangement is generally like the arrangement of the corresponding parts shown in United States Letters Patent No. 1,288,436, granted Dec. 17, 1918, on an application of B. F. Mayo. Casings 44 are arranged to slide in arms 48 carried by the machine fra-me as described in the above-identi fied patent.

Integral with, or attached to, each casing 44 is a member 50 (Figs. 1 and 2) connected by a link to a bell crank lever 52 connected by links 54 with a bar 56 which is urged toward the rear of the machine by a coil spring 58. Bar 56 is o erated to close the jaws by a push rod 60 Fig. 1) o erated by a bell crank lever 62 connected y a link 64 wit-h a treadle 66. Treadle 66 `is arranged to be depressed against the resistance of a spring 68 and to be held in its lowered position by a pawl 7 0 engaging a ratchet 72 until released by the operator. bExcept for the connection to the treadle the above described operating connections for jaws 36 maybe,and are shown as being, the same as the corresponding parts illustrated in the above-'identified patent.

The position of the shoe at the time it is gripped by these jaws is illustrated as determined by a back gage 74 (Figs. 2, 4 and 5) carried by a support 76 (Figs. 4 and 5) which also carrles creaseplates 78 formed to leave a cut out portion 80 between them so that they enter the rand crease about the rear end of the shoe and support the periphery of the sole. The support 76 may, if desired, be made in two parts as shown in Fig. 4, joined Vby a dovetail joint 82, or two separate plates might-be provided yieldingly urged together and separated for the insertion of a shoe by being connected to treadle 66 in the same manner as described in United States Letters Patent No. 1,307,285, granted September 14, 1915, on an application of S. J. lVentworth and F. H. Perry.

The support 76 is carried by a slide 84 mounted in the frame of the machine for sliding movement backward and forward to vary the position of plates 78 and gage 74, in order to change the position of a shoe supported by jaws 36 to determine the position of the heel breast line, and thus to vary the length of the heel seat according to the length of the heel seat surface of the heel which is to be attached. In order properly to position the back gage 74, the heel to be attached, or one like it, is placed on a horizontal support 86 with one edge of its heel seat surface in engagement with a fixed abutment 88. The length of the seat surface of the heel is measured by a movable gage'member 90 carried by an arm 92 adjustably attached to slide 84. To -facilitate the operation of this measuring device and the simultaneous movement of slide 84 with said gage 74, arm 92 is continued to form a rack 94 operated by a pinion 96 mounted on a shaft 98 to which is attached a manually operable lever 100. To prevent the setting of the machine from being unintentionally disturbed, lever 100 carries a spring-pressed plunger 102 arranged to engage frictionally with a segment 104.

As best shown in Fig. 8, the shoulders or abutments on opposite sides of the sole at theV heel breast line are formed by a pair of angular knives clamped by screws 112 in the split ends of arms 114, said shoulders being designedto co-operate with a correspond- -ing portion of the heel. Arms 114 are carried by lever members 116 mounted to turn on short shafts 118 carried by sleeves 120 se cured to the bottoms yof vertical adjusting shafts 122. Adjusting shafts 122 pass vertically through a bracket 121 on the front of a slide 123 carried by the machine frame and may be turned, to adjust the angle at which knives 110-operate on the'sole, by gear segments 124 clampedr to their upper ends by screws 126. Gear segments 124 are operated by a rack on a rotatable adjusting member 128 provided with a nur-led handle and thread at'its rear end into slide 123. VKnives 110 may be adjusted vertically by releasing screws 126 and then turning hand screws 127 which bear against the upper ends of shafts 122. Springs are provided to co-operate with the screws 127 to determine the position of the knives.

Lever members 116 are operated to rock knives 110 toward the sole by pitmen 140 connected thereto by` suitable swivel joints 142 (Figs. 2 and 8). Pitmen 140 are connected by ball and socket joints to diverging arms of a rock member 144 (Figs. 1, 2, 3 and 6) which is formed with a vertical operating arm 146 connected by a link 148 with a bell crank lever 150 (Fig. 1) mounted on a shaft 34 and carrying a cam roll engaging a cam 152 on cam shaft 32 (Fig. 2). Knives 110 are operated in a curved path about horizontal axes outside the plane of the sole as illustrated in Fig. 8 to form shoulders at the heel breast line, moving from the edges of the sole inwardly and from the attaching surface through to the tread surface, and are then immediately withdrawn. By manipulation of the adjusting member 128 the angle at which the knives operate can readily be adjusted, and their height can be adjusted by screws 127 against the resistance of springs 125. Itwill be noted that the form of the yshoulder cut in the sole may be changed by using a knife of a different formation.

After the shoulders have been formed as above described, the Waste material about the rear of the periphery of the sole is removed by a cutting tool (Figs. 1 and 2), illustrated as provided with three curved knife blades, clamped in the ends of arms formed onk a rock member 162 mounted on a shaft 163 carried by arms 164 depending from slide 123. As shown in Figs. 1 and 2 each blade is in the form of a-portion of a cylindrical surface with a straight cutting edge constituting an element of the cylinder. Rock member 162 is operated to insert and withdraw the knives by a link 168 connected to a rock arm 170 shown as integral with rock member 162, link 168 being connected to a cam operated lever 169 (Fig. 1). In the embodimentof the invention illustrated in the drawings, one of the knife blades operates down each side of thesole and the third op` erates to remove the waste stock from the rear end of the sole as 'the knives move rectilinearly from the heel breast line toward the rear. Thus the sole is trimmed as illustrated'in Figs. 9 and 10.

A presser foot is also carried by slide 123 (Fig. 1) and is urged downwardly by a spring 182 against the sole of the shoe immediately in advance of knives 160.

Presser foot 18() is mounted on the 'bottom of a rod surrounded by spring 182, the top of the rodbeing formed as a threaded stem carrying lock nuts 184 arranged to be engaged by a fork at the forward end of a lever 186 pivoted on the standard attached to slide 23 rear end of lever 186 is turned downwardly and is arranged to engage, near the end of the rearward movement of slide 123, with a stationary rod or abutment 190 carried by the machine frame in order to lift presser foot 180 from the work (Figs. 1 and 3).

l/Vhen the presser foot is thus lifted from the work at the end of the cycle of operation .i

of the machine, it is latched in its upper position by the nose of a plunger 183 urged by a spring 187 under a lug 185 carried by lever 186. The plunger 183 is guided by a sleeve on the slide 123, or in any other suitable manner. l/Vhen the slide 123 moves forward during the first part of the next cycle of operation of the machine, the presser foot is held latched in its upper position. When the rock member 144 is turned to operate the knives 110, a projection 191 (Fig. 6) on the` `rock member engages a sleeve 189 clamped to the plunger 183, withdrawing the plunger yfrom beneath the lug on the lever 18.6, and allowing the spring 182 to force the presser 'foot against the work. This occurs before the knives 110 have .actually begun to cut.

Slide 123 is connected by a link 192 with a bell crank lever 194 operated by a cam on cam shaft 32, arranged to move slide 123 forward and back at appropriate times in the operation of the machine.

1n operation, a heel is first placed on support 86 in engagement with abutment 88, and handle 10() is manipulated to bring gage member 90 against the opposite edge ofthe heel seat surface of the heel, thereby to adjust the back gage 74. Then the lasted shoe which is to be fitted for the heel so measured is placed in the machine by the operator, with its back seam against the back gage 74 and with the crease plates 78 in the rand crease of the shoe which carries rock member 144. The

supporting the periphery of the sole. At this shoetdhld Jit in position, treadle 66 being held'down during the operation of the maohinehypawl 70. Thus the shoe is held with itsheelabreast line in .position to be operated on Eknives 1:10.

\ seeing that the shoe is properly positionedn the machine, the operator manipulates treadle lever 26 to connect shaft 22 to shoulders have been formed by these knives,

th'e'knives' are entirely withdrawn from the work. i Lever 169 is then operated by its cam to rock member 162;in sucha manner as to bring the cutter or knives 160 into engagement with the tread surface of the sole. The edge portions of the Soleto the rear of the transverse cut made by knives 110 project upward ly, as shown in Fig. 7, being deflected by the joint action of plates 78 and presser foot 180,

while forward of this cut the edges of the sole are held down by the sole attaching stitching andlie relatively fiat. Thus knives 160 are positioned to enter the substance of the upwardly projecting edge portion of the sole at the heel-breast line, their cutting edges being substantially in engagement with and parallel to the median ortlon of the heel-scat of the `sole. Wh e Aknives 160 are held in this vposition lever 194 is operated to pull slide 123 toward the `rear of the machine, link 168 being simultaneously pulled rearwardl by lever 169. Slide 123 carries also e mechanism for operating knives 110, which at this time merely rides idly back and forth as the knives have been withdrawnfrom the Work, and also'carries presser foot A180 and knives 160 together with their operating mechanism. The central part ofthe sole is pushed down between supports 78 by the presser foot, to distort the sole as shown in Fig. 7, so that the side knives V16() trim off the waste material, forming a shoulder. as shown in Figs. 9 and 10. The central knife 160 is at this time above the sole and has no cutting action- As the slide 123 nears the end of its rearward movement, presser foot 180 is lifted by engagement of lever 186 with abutment 190 to bring it above the level of supports 78, and at approximately the same time the central knife 160 operates to trim off the rear part of the sole which projects above supports 78. Further rotation of shaft 32 returns all the various parts to their initial positions whereupon the machine comes to rest and the operator, after tripping pawl 7 (l,V removes the shoe from the machine. It will be noticed that as knives 160 move from the heel breast line rearwardly they tend to tension the sole during the entire trimming operation, thus obviating any tendency to buckle and producing an operating condition conducive to clean cutting.

As illustrated in Fig. 9, the heel seat of a shoe has been fitted for the attachment of a Louis heel, knives 110 having entered the sole as shown in Fig. 8 in a path substantially at right angles to its periphery to form breast cuts 154. Fig. 10, on the other hand, illustrates a shoe fitted for the attachment of a Cuban heel, knives 110 having a component of movement in a direction rearwardly of the shoe so that the shoulders formed at 156 in the sole correspond in form to the curved breast Yof a Cuban heel.
