This invention relates to trimming machines and is herein illustrated as embodied in a machine for trimming heel coverings.

In covering wooden Louisheels it is the usual practice to cover the rear portion and the sides of the heel with one piece of covering material, to turn theforward marginal portions of the covering inwardly over the breast corners of the heel, and to secure them uponthe lateral marginal portions of the heel breast. The breast of the heel is then covered'with a separate covering which overlaps the inturned sidecover margins, and finally the separate breast covering is trimmed flush with the sides of the heel. When covering a heel in this manner precision in trimming the marginal portions of the side covering which are to be turned over the breast corners is not essential since these margins are subsequently covered by the breast covering.

There are certain disadvantages, however, in having the lateral edges of the heel-breast covering flush with the sides of the heel and, in order to avoid these disadvantages and to provide improved heels which are neat in appearance, certain improved features of covered heel construction have been disclosed and claimed in United States Letters Patent No. 1,691,149 issued November 13, 1928 on application filed in the name of Anthony Cocozella, and in United States Letters Patent No. 1,704,204 issued March 5, 1929 on application filed in the name of William H. Nutt. As fully expained in the Nutt patent, relatively narrow grooves are made in the breast of a heel adjacent to the breast corners so as to form a rib extending along each lateral margin of the heel breast. In covering a heel prepared in this manner, a covering for the rear and sides of the heel is applied with its forward marginal portions covering the ribs on the heel breast and tucked into and secured within the grooves at the inner sides of the ribs, while the portions of the breast surface between the ribs is covered by a separate covering, for example a flap split from the sole of the shoe, the lateral margins of which covering are also tucked into and secured within the grooves beside the tucked in margins of the side covering. The Cocozella patent, above referred to, discloses a heel having a shallow recess in its breast surface for the reception of a covering such as a breast-covering flap split from the sole of a shoe, the recess being of less width than the breast surface of the heel and thus forming ribs which extend along the opposite lateral margins ofthe heel breast so that the covering may be fitted within the recess with the opposite edges of the covering hidden from view and protected by heel material at the opposite sides of the recess. While the Cocozella patent shows the opposite forward marginal portions of the cover for the rear and sides of the heel as covering the ribs on the heel breast and terminating flush with the sides of the recess between the ribs,

the side covering, if desired. may be tucked into the recess in a manner similar to that in which the side cover margins are tucked into the grooves in the Nutt patent.

In covering heels of the improved types above referred to, it is obvious that both the side covering and the breast covering must be trimmedaccurately in order that their marginal portions can be fitted properly into the recess or the grooves. It is very diflicult to trim the side and the breast coverings by hand and such a process is slow and requires such a high degree of skill on the part of the operator as to make it commercially impracticable. Moreover, when the heel coverings are trimmed they are usually in temper, and if trimmed to exactly the same size as the portions of the heel which they are to engage they sometimes shrink as they dry and will not fit properly. It is therefore preferable to allow for shrinkageby trimming the coverings slightly oversize. Oversize trimming adds to the difliculties of hand trimming of heel coverings for the improved heels above disclosed.

An object of the present invention is to provide an. effective and reliable machine for trimming the side coverings of heels as well as the breast coverings of heels for reception either in recesses. or in narrow grooves formed in the breasts of the heels.

NVith the above objects in view and in accordance with a feature of the invention, the illustrated machine comprises instrumentalities comprising a knife and a shearing member for trimming a covering attached to a heel to prepare a marginal portion of the covering for insertion in a narrow groove in the breast of the heel, and a gage arranged for positioning between the covering and the heel as well as adjustable relatively to the shearing member and having a narrow portion constructed and arranged to engage within the narrow groove to facilitate the positioning of the covering relatively to the trimming instrumentalities. The gage for assisting the operator in positioning the covering relatively to the trimming instrumentalities so that the marginal portion of the covering when trimmed will fit accurately is made narrow to engage within the groove during the trimming operation as the heel in the groove, is moved to present different portions of the covering to the trimming instruinentalities. In accordance with another feature of the invention, the illustrated machine is provided with instrumentalities comprising an oscillating knife and a shearing member for trimming a side coverin of a heel to prepare a marginal portion t iereof for reception in a recess in the breast of the heel and a gage located at a substantial distance from the shearing member, the gage being arranged for positioning between the covering and the heel and being constructed and arranged to engage a side wall of the recess to facilitate the positioning of the covering relatively to the trimming instrumentalities. In order to retain the covering adjacent to the oscillatin knife and the shearing member during the trimming of the heel covering, the illustrated machine is also provided with covering guides constructed and arranged to engage the covering, thereby to assist in positioning the covering between the knife and the shearing member. When fitted for trimming side covers, the illustrated machine includes means for preventing the ortion of the side coverin which is later to V inserted into the recess 1n the heel breast, from being acted upon by the trimming means until the operator has properly positioned the work relatively to the machine.

The invention will now be described with reference to the drawings, which illustrate preferred embodiments thereof, and pointed out in the claims.

- Fig. 9 is a front view of a trimmer. of the same type as the trimmer shown in Figs. 5 and 6 but provided with attachments for trimming the marginal portion of a heel side covering extending beyond the rim of the attaching face of a heel to repare said marginal portions thereof for eing folded over and secured to the attaching face of the heel Fig. 10 is a perspective view of the rear portion of a shoe and illustrates a finished heel the covering of which has been trimmed by the above machine; and

Fig. 11 is a sectional view of a covered heel of the type having a recess in its breast, into which recess a heel breast covering has been inserted, the marginal portions of the side covering having been turned into the recess to register with the sides of the recess.

As shown in the drawings, the improved heels above described are provided with a covering 12 for the rear and the sides of the heel, which covering has marginal portions 14 (Figs. 5 and 6) extendin beyond the breast corners 16 of the heel. he marginal portions 14 of the side covering are prepared for laying upon the breast of the heel so as to cover the ribs 18 and are to be tucked into narrow grooves 20 adjacent to the breast corners or secured to the side walls of a recess 22 (Fig. 6) formed in the heel breast.

The covering 24 (Figs. 2 and 3) for the breast of the heel between the grooves 20, which covering 24 is illustrated as split from the sole to cover the breast of a Louis heel, has its marginal portions 26 extending beyond the breast corners 16 of the heel, which marginal portions 26 are to be prepared 1... Arc-cw tion in the grooves 20 beside the tucked-in margins 28 (Figs. 3 and 11) of the side covering 12. Where the heel breast is provided with a recess 22 (Figs. 6 and 11) the breast covering is inserted in the recess as shown in v Fig. 11 so that its opposite edges 30 (Fig. 11)

are hidden from View and abut against the tucked-in margins 28 of the side covering 12.

The illustrated machine is constructed and arranged for preparing the marginal portions 14 of the side covering 12 for reception within the grooves 20 or within the recess 22 and for preparing the marginal portions 26 of the heel breast coverings for reception within the grooves 20 and comprises a standard 32 (Fig. 1) for supporting an elongated head 34 the ends of which are enlarged to form housings 36 for carrying the heel covering trimmers 38 and instrumentalities for operating the same.

The right and left trimmers 38 illustrated in Fig. 1 are alike except'th'at their trimming instrumentalities are reversed in order that the operator may trim the marginal portions of the heel covering by starting the trimming out at the top-lift-receiving face of the heel and progressing toward the attaching'surface of the heel. Either of the trimmers, however, may be used foF trimming either of the marginal portions of the heel covering, if desired. Since the trimmers are substantially duplicates, only one of the trimmers need be described in detail.

Power for operating the machine is supplied by a motor 40 which drives a pair of pulleys 42 through belts 44. In order to effect oscillatory movement of a knife 46 from the rotation of the pulley 42, the illustrated machine is provided with a shaft 48 (Fig. 2) upon which the pulley 42 is mounted and which has an eccentrically mounted pin 50 extending from its forward end, the pin 50 carrying a sleeve 52 provided with a downwardly extending arm 54 having a recess carrying a connecting pin 56.

The forward portion 58 of the housing 36 forms a bearing for a rod 60 extending forwardly and rearwardly of the machine, which rod 60 projects beyond the front portion of the housing 36 and carries a hub 62 having a depending arm 64 to which the oscillating knife 46 is secured by a clamp 66. The rear portion of the rod 60 extends into an opening 68 (Fig. 2) of the housing 36 and carries a hub 70 provided with a bifurcated extension 72 which straddles the downwardly extending arm 54 of the sleeve 52 and has recesses for receiving the connecting pin 56. The hub 70 may be fixed to the rod 60 by any convenient means, such as a pair of set screws 74. Rotation of the shaft 48 causes the sleeve 52 which is mounted upon the eccentric pin 50 to be raised and lowered, thereby effecting the oscillation of the bifurcated arm 72, the rod 60 and the knife 46.

The forward portion 58 of the housing 36 also forms a bearing fora supporting rod 76 which extends forwardly and rearwardly of the machine: The forward end of the rod 76 projects beyond the front of the housing 86 and carries a bracket 78 (Figs. 1 and 2) which is fixed to the supporting rod 76 by a set screw 80. The bracket 78 carries a gage 82 (Figs. 2 and 4) and a shearing member 84.

It is sometimes desirable, particularly when the machine is used by an inexperienced operator, accurately to position the heel relatively to the gage 82 and the shearlng member 84 before the oscillating knife 46 and the shearing member 84 are placed in cutting relation relatively to one another. Accordlngly, the bracket 78, which is fixed to the supporting rod 7 6, is mounted so as to permit it to be swung toward and away from the 0scillating knife 46 or to cause it to be fixed relatively to the oscillating knife 46, as Wlll presently appear.

In order to control the arc through which the bracket 78 may be swung, the housing 36 is provided with a lug 86 (Figs. 1 and 2), which is fixed thereto by screws 88. The lug 86 has a recess 90 (Fig. 2) at its lower port on for receiving a spring 92, one end of which engages a face 94 of a downwardly extend ng portion 96 of the bracket, and extending through the top portion of the lug 86 1s a set screw 98 the end portion 100 of which normally engages a face 102 of the bracket 78. The spring 92 tends to urge the bracket 78 in a clockwise direction about the axls of the supporting rod 76, the rotation being l1m1 ted by the set screw 98. The set screw 98 ordinarily is positioned (Figs. 1 and 2) so that the face 94 of the downwardly extending port1on96 of the bracket 78 engages the face 104 (Fig. 2) of the lug, thereby holding the bracket 78 rigid relatively to the housing 36 and the oscillating knife 46. When the screw 98 has been moved to the right (Figs. 1 and 2) the machine is adjusted to permit movement of the bracket 78 so that the shearing member 84 and the gage 82 are out of trimming relation with one another when the machine is idle, the bracket being moved in a clockwise direction by the spring 92 until the face 102 of the bracket abuts against the end portion 100 of the screw 98.

The gage 82 and the shearing member 84 are rigidly supported from the bracket 78 by a downwardly extending bar 106 which is secured in adjusted relation to the bracket 78 by a set screw 108, thereby positioning the gage 82 and the shearing member 84 as a unit relatively to the oscillating knife 46. A plate 110 (Figs. 2 and 3) having openings therein for an extension rod 112 of the gage 82 and an extension rod 114 of the shearing member 84 is secured to the bottom portion of the bar 106 and is provided with set screws 116 by which the gage 82 and the shearing member 84 are secured in adjusted relation relatively to one another. In order to assure that the gage 82 and the shearing member 84 will be rigidly fixed to the bracket 7 8, the plate 110 may be attached at its rear portion by a screw 118 (Fig. 2) to an extension member 120 which is secured to the lower end of the vertically extending portion 96 of the bracket 78.

The gage 82 (Fig. 4) near its lower end is provided with a concave portion 122 which has a recess 124 for receiving the leading portion 126 of the cutting edge 128 of the oscillating knife 46. The rear portion 130 of the gage is recessed throughout its length for the reception of the shearing block 84' the lower shearing edge 132 of which cooperates with the cutting edge 128 of the knife 46 for trimming the heel-breast covering. The concave portion 122 of the gage 82 is arranged to engage the covered rib 18 of the heel and is formed and arranged to enter the narrow groove 20 in order to engage within the groove as the heel is moved to present different portions of the covering to the trimming instrum'entalities. The term groove as used herein may define either the original groove which was formed in the heel or the portion of the original groove remaining after the side covering has been received in the original groove, and the term side of the groove may define the side of the original oove or the side formed by the side coverlng which has been received within the groove. The term recess is used in the generic sense and includes a narrow groove as well as a wide groove extending substantially from one breast corner to another, as shown in Fig. 6.

In order to assist in retaining the covering of the heel, which coveringis liable to be drawn back with the knife 46 due to the adhesiveness of cement upon the covering, the machine is provided with a flap guide 134 adjacent to the shearin member 84 so that the covering will readi y feed between the shearing member 84 and the knife 46, which flap guide is adjustably secured at 136 (Fig. 3) to the vertically extending portion 96 of the bracket 78.

A heel having its breast covering prepared for reception in the grooves is guided past the trimmer (Fig. 2) by hand, the gage 82 which engages within the groove 20 assisting the operator in correctly positioning the breast covering relatively to the trimming instrumentalities so as to prepare the marginal portions of the breast coverin accurately to be received in the grooves. f it is desired to swing the bracket 78 so that the knife 46 and the shearing member 84 will not cooperate with one another to sever the marginal portion of the covering until the operator has correctly positioned the work relatively to the gage and the shearing member, the screw 98 is rotated a few turns out wardly. With the machine adjusted in this way, the work is properly positioned while the knife 46 oscillates idly, and the operator then presses the heel toward the knife 46, thus swinging the bracket 78 toward the knife until the face 94 of the bracket 78 engages the lug 86 at which time the shearing member 84 and the knife 46 cooperate to trim the covering and the heel is moved past the trimmers to complete the operation as above described.

The machine is shown in Figs. 5 to 8, inclusive, as fitted to prepare the marginal portions of the side covering for reception in the grooves 20 or in the recess 22 in the breast of the heel, the machine so fitted differing from the machine above described only by the substitution of a different type of bracket 138, shearing member 140 and gage 142 for the bracket 78, shearing member 84 and gage 82 already described.

In preparing the marginal portions of the side coverings for reception in narrow grooves 20 or in a recess 22 in the breast of a heel, it has been found unnecessary to use a bracket mounted for swinging movement and it is preferable to use the bracket 138 which is quite similar to the bracket 78 already described, the bracket 138 being held rigidly relatively to the housing 36 by a lug 144 secured to the housing 36 by screws 88. A horizontally extending portion 146 of the bracket 138 is provided with an opening 148 for supporting the shearing member 140 and the age 142.

Tlie shearing member 140, which is secured to the bracket 138 by a wedge-shape clamp plate 150, comprises a downwardly extending portion 152 (Figs. 5 and 6) having a shearing insert 154 secured thereto, which insert has a lip portion 156 (Fig. 5) provided with a beveled edge 158 arranged to cooperate with the oscillating'knife 46 for severing the heel covering. The top portion of the shearing member 140 has an offset portion 160 which is recessed lengthwise of the shearing member and receives a gage supporting column 162. The gage supporting column 162 and the shearing member 140 -carried thereby are secured against movement relatively to the shearing member 140 by a screw 164 carried by the supporting column 162 and extending through a slot 166 (Fig. 5) in the offset portion 160 of the shearing member 140, the screw 164 having a collar 168, between which collar 168 and the supporting column 162 the shearing member 140 may be rigidly clamped. The supporting column 162, which carries the gage 142, may be adjusted relatively to the shearing member by a screw 170 which is rotatably fixed within an extension 17 2 of the supporting column 162 and enters a threaded hole 17 4 in the upper face of the bracket 138. In order to adjust the gage 142 relatively to the bracket 138 the set screw 164 is loosened and the screw 170 is turned until the desired adjustment is made; the set screw 164 is then tightened for rigidly holding together the gage 142 and the shearing member 140.

llnexperienced operators sometimes find difficulty in starting the trimming operation without severing too much material along the marginal portion of the side covering as indicated by the line 176 (Fig. 5), this being caused by the gage not being properly located relatively to the work before the severing of the marginal portion of the covering is begun. When the marginal portion of the side covering is trimmed in this manner, the portion of the side covering which is to be secured in the groove adjacent to the toplift-receiving face of the heel is too short to be properly secured in the groove, with the result that the covering will soon start to come off. In order that the operator may position the gage in the groove in such a manner that the work will be properly presented to the machine before the trimming instrumentalities start to sever the marginal portion of the side covering to the left of the position indicated by the line 178 (Fig. 5), the gage is provided with an arm 180 (Figs. 5 and 8) having a thin curved heel engaging portion 181 located at a substantial distance from the shearing member and constructed to engage the breast of the heel and engage within the groove 20, which arm 180 is hinged to an extension 182 of the column 162 (Figs 5 and 8). The lower face 184 of the column extension 182 (Fig. 8) and the upper face 186 of the arm 180 are provided with recesses 188 in which a spring 190 is inserted, the spring 190 normally urging the arm 180 forward of the shearing member 140, as shown in Fig. 8. By arranging the arm so that it leads the trimming instrumentalities, the operator is able accurately to position the gage 142 in the groove before the trimmer begins to sever any portion of the side covering which is later to engage within the groove 20. When the gage 142 has been properly positioned within the end of the groove 20 the pressure of the heel against the gage for moving the heel past the trimmer will cause the arm 180 to swing clockwise (Fig. 8) until the face 186 of the arm engages the lower face 184 of the column extension 182. -Where the operator is experienced it is generally unnecessary to swing the arm 180 during the trimming operation,

the arm being held rigidly relatively to the supporting column .162 by a set screw 192, which maintains the upper face 186 of the arm 180 against the lower face 184 of the supporting column 162.

In order to assist in retaining the marginal portions 14 of the side covering between the beveled edge 158 of the shearing member 140 and the knife 46, a flap guide 194 (Figs. 5, 7 and 8) similar to the flap guide 134 (Fig. 3), used in trimming the breast flap above described, is used, the flap guide 194 be: ing secured to the bottom of a vertically extending portion 196 of the bracket 138 by a clamp 198.

In preparing the lateral marginal portions of a relatively stiff side covering, the marginal portions 14 (Figs. 5 and 7 extending beyond the breast corners of the heel have a tendency to lean toward the breast of the heel, as shown in Fig. 7. In order to straightenthe marginal portions 14 extending beyond the breast corners of the heel so that they will not interfere with the proper operation of the shearing member 140 and the gage 142 as the heel is moved past the trimming instrumentalities, the machine illustrated in Figs. 6 to 8 is provided with a flap guide 200 (Fig. 7) which is fixed to the shearing member 140 by screws 202 threaded into holes 204 (Figs. 5 and 6) in the shearing member 140.

The above illustrated machine may also be conveniently used for preparing the marginal portions of a side covering 206 (Fig. 9) extending beyond the rim 208 of the attaching face 210 of the heel for belng folded over and secured to the attaching face of a heel. The trimming means of the machine when fitted for this operation are provided with a gage 212 having a hook portion 214 extending toward the knife 46 and having a roller 216 mounted at its end. The roller 216 is guided around the rim 208 of the attaching face 210 of the heel as the knife 46 severs the marginal portion of the side covering 206 extending beyond the rim of the attaching face of the heel, as shown in Fig. 9.

In order to prepare the marginal portions 14 of the side covering extending beyond the breast corners 16 of the heel for reception within grooves 20 in the breast of the heel, the operator presents the work to the machine as shoWn in Fig. 5, the marginal portions 14 of the side covering being positioned relatively to the trimming instrumentalities with the assistance of the gage 142, the engaging portion 181 of which is in contact with the breast of the heel and engages within the groove 20. The trimming cut is started at the end of the heel adjacent to the top-liftreceivin face of the heel, the operator moving the eel by hand past the trimming intively to strumentalities and retaining the gage with in the groove 20 as the trimming progresses toward the attaching face of the heel;

7' In preparing the marginal portions of the side covering 14:1extending beyond the breast corners 16 of the heel for reception within a recess 22 in the breast of the heel, the procedure is substantially similar to the operation above described except that the heel engaging portion 181 engages the bottom and one of the sides of the recess during the trimmin operation, as shown in Fig.
