12 Claims.

This invention relates to machines for removing material from the forwardly projecting lips of Louis heels to fit them for use in practicing the method disclosed in United States Letters Patent No. 2,125,328, granted August 2, 1938, on an application filed in my name.

It is an object of this invention to provide a machine for quickly and effectively grinding excess material from the forwardly projecting lip of a Louis heel to such an extent as to insure that when the heel is properly positioned upon a shoe its lip shall snugly engage a heel-breast receiving shoulder formed upon a prefitted sole attached to the shoe.

With the above object in view, and in accordance with a feature of this invention, there is provided a heel fitting machine comprising gages constructed and arranged to be engaged by the rear end of a shoe and a heel-breast receiving shoulder, respectively, formed upon an attached sole of the shoe, an abrading tool, a carrier for a Louis heel which is to be attached to the shoe, means for effecting relative movement of said carrier and said abrading tool in a predetermined path extending lengthwise of the heel to remove material from the entire width of the forwardly projecting lip of the heel, thereby reducing the length of the heel, and means comprising connections between one of said gages and the heel carrier for controlling the extent of said relative movement of the carrier and the tool in said path in accordance with the length of the heel seat of the shoe measured by said gages. In the illustrated machine the Louis heel is positioned and held in place upon the carrier, the forwardly projecting lip of the heel extending beyond the carrier and being arranged in opposed relation to the abrading tool which is of the rotary type. The carrier is mounted for pivotal movement toward andaway from the tool and has secured to it a plate the front edge of which is constructed and arranged to be engaged by the heel-breast receiving shoulder of the attached sole of the shoe. The heel carrier and the plate are normally held forward in their idle positions away from the tool and a fixed stop; respectively, by a spring. In operating the machine the heel-breast receiving shoulder of the attached sole of the shoe is forced against the front edge of the plate, causing the plate and the carrier to be swung rearwardly against the action of the spring, thereby forcing the projecting lip of the Louis heel against'the abrading tool to grind material from the end of the lip. The

the amount of material removed from the lip, is limited by the engagement of the rear end of the shoe adjacent to its heel seat with the fixed stop. The construction and arrangement of the car rier, the plate, and the stop are such that when the shoe has been forced against the stop the length of the attaching face of the heel operated upon is equal to the length of the heel seat of the shoe, thereby insuring that when the heel is properly positioned upon the shoe the front edge of its forwardly projecting lip shall snugly engage the heel-breast receiving shoulder of the attached sole of the shoe.

The above and other features of the invention will be understood and appreciated from the following detailed description read in connection with the accompanying drawings, in which Figs. 1 and 2 are perspective and side views, respectively, partly broken away, of an illustrative abrading machine in the process of removing material from the forwardly projectin lip of a Louis heel;

Fig. 3 is a plan View of the plate which is moved by the shoe to force the heel upon the carrier against the rotary abrading tool;

Fig. 4 is a plan view showing the prepared heel seat of the shoe which is to receive the Louis heel;

Figs. 5 and 6 are perspective and bottom views respectively of the Louis heel to be attached to the shoe, the portion of the lip removed by the machine being indicated by dash lines; and

Fig. 7 is a perspective view, partly broken away, of the heel end of the shoe illustrated in Fig. 4 after the heel has been attached to the shoe but before the flap has been applied to the breast of the heel.

In the above-mentioned United States Letters Patent No. 2,125,328 there is disclosed an improved method of shoe-making which consists in splitting a sole 20 (Figs. 4 and 7), before its attachment to a shoe 22 mounted upon a last 24, to form a heel-breast covering flap 26 and simultaneously therewith removing a layer of sole material to form at the base of the flap a single heel-breast receiving shoulder 28 of substantial height extending from one side of the sole to the other, reducing the heel-seat portion of the sole to form a tab 30 (Fig.4) attaching the sole to the shoe, removing material whenever necessary from the forwardly projecting lip 32 of a Louis heel 3 4 to be attached to the shoe in order to insure that when the heel is accurately positioned upon the shoe its forwardly projecting lip 32 shall degree of swing of the carrier, and accordingly 55 snugly engage the heel-breast receiving shoulder 23, attaching the heel to the shoe, and then applying the heel-breast covering flap 26 which preferably has a relatively thick base portion 36 to the breast 38 (Fig. of the attached heel.

The sole may advantageously be split before its attachment to the shoe by the use of the machine disclosed in United State Letters Patent No. 2,173,822, granted September 26, 1939, on an application filed in my name. Such machine comprises a rotary tubular saw (not shown) which not only splits the flap 26 from the sole 20 but also removes a layer of sole material to form the heel-breast receiving shoulder 23 (Figs. 4 and '7) at the base of the flap.

The machine illustrated herein will be de- 1 scribed with reference to removing material indicated by dash lines (Figs. 5 and 6) from the forwardly projecting lip 32 of the Louis heel to be attached to the shoe, so as to trim the heel to fit the prepared heel seat Ali) (Fig. i) of the shoe, the length of the attaching face of the untrimmed heel usually being greater than the length of the prepared heel seat of the shoe. The forward portion of the lip 82 of. the heel is of a thickness equal to theheight of the heelbreast receiving shoulder 23 and is uniformly thick not only throughout the width of the .heel but for a short distance rearward from the front edge 22 (Figs. 5 and 6) of the untriznmed lip,

which edge is commonly included in a plane, as

shown in Fig. 6.

As explained in the above-mentioned United States Letters Patent No. 2,125,328, before the sole 2B is attached to the shoe 2?. its heel-breast receiving shoulder 28 is included in approximate- 5:.

28 of the attached sole of the shoe, as viewed in .1

plan (Fig. 4), varies in accordance with the transverse convexity of the shank portion of the shoe bottom.

It will be appreciated that in order that the front edge (Figs. 5 and 6) of the reduced lip of the heel 3 shall be approximately complemental to the heel-breast receiving shoulder 28 of the attached sole 2!), the lip 32 should be arched heightwise of the heel, as shown in'Fig.

5, in accordance with the transverse convexity of the forward end of the tab 30 of the attached sole, and the front edge 49 of the lip of the-heel should be concaved to a depth 48 (Fig. 6) to accommodate the rearwardly bowed heel-breast.

receiving shoulder 28 (Fig. 4). When it has been attempted to concave the forward edge of the lip to a form exactly complemental to the rearwardly bowed heel-breast receiving shoulder it has been found that objectionable gaps frequently appear at the sides of the finished shoe between the heel-breast receiving shoulder and the lateral margins of the lip of the heel.

In order to obviate this trouble the depth 38 (Fig. 6) of the concavity at the front edge 46 of the lip 32 is made slightly deeper thanthe extent M (Fig. l) of the rearward bowing ofthe heelbreast receiving shoulder 28, thereby insuring that the lateral margins of the lip shall snugly engage the margins of the heel-breast receiving shoulder. Withsuch a construction no gaps such as above referred to appear at the sides of the finished shoe between the heel-breast receiving shoulder 28 and the lip 32 of the heel, although the median portion of the lip of the finished shoe is arranged close enough to the heel-breast receiving shoulder to insure that the relatively thick base portion 35 of the flap secured to the breast of the attached heel shall overlie the breast joint without showing the slight gap which is formed between the median portion of the front edge 46 of the lip and the heel-breast receiving shoulder 28 and which is usually filled up by cement.

Material may be quickly and effectively removed from the lip 32 of the heel 34 by the use of the illustrated machine which comprises a plate or gage 59 the lateral margins of the arched front edge 52 of which are constructed and arranged to be engaged by the heel-breast receiving shoulder 28 of the attached sole 2a of the shoe 22, an. endless abrading belt 54 mounted upon a pair of cylindrical rolls 56, 58 (Fig. l), a stop or gage 6t, and a heel carrier 62 (Fig. l) to which the plate 53 is secured by screws 64. The heel carrier 62 is constructed and arranged to be swung, together with the plate 5%, under pressure of the heel-breast receiving shoulder 23 of the attached sole 28 of the shoe 22, against the edge '52 of theplate, until the shoe engages the stop Eli, thereby forcing the lip 32 of the untrimmed heel against the cylindrical portion 66 of the abrasive surface of the belt 54, which surface may be referred to as a rotary abrading tool, to remove material from the lip of the heel in accordance with the length of the prepared heel seat-til (Fig. 4) of the shoe.

The carrier 62 comprises a table 68 for supporting the heel, an abutment 18 which may be secured in different adjusted positions upon the table and has an undercut heel-engaging face l2, and a positioning or orienting frame 1 3 for forcing the heel against the abutment. In order to enable the operator initially to aline the heelengaging face 12 of the abutment l0 with the lateral margins of the arched portion of the edge 52 of the plate 59 for reasons which will appear later, the abutment if! is provided with a depending flange it fitting in a guideway E8 of the table as, and has a slot 86 through which passes a clamping screw 82 threaded into the table. The axis of rotation 8 (Fig. 1) of the cylindrical roll 56 is parallel to the heel-engaging face l2 of the abutment l9 and is arranged at right angles to the lengthwise direction of the guideway 18 of the table 68. The heel is positioned upon the table 68 with its central heightwise-plane 88' (Fig. 6) disposed at right angles to the axis of rotation 84, by the positioning frame it which engages the relatively flat upright portion of the breast of the heel and forces the rear end of the heel with considerable pressure against the face '12 of the abutment Til.

The positioning frame M is mounted on a pivot pin 38 secured to 'a depending flange 90 (Fig. 2) of the table 63. When the machine is idle a face 92 of the heel-positioning frame '14 is held by a spring 94 against a lug 95 of the flange 91'! of the table 63-. The heel may be quickly placed-upon the tablet? by swinging the positioning' frame rearwardly under pressure of the heel-against the action of the spring 94 and then releasing the heel, the rear end of which is then forced against the face 1'2 of the abutment Ill by the positioning frame, the heel at the same time being'properly oriented upon the table with its heightwise median plane 86 (Fig; 6) arranged at right angles to the'axis of rotation 34 (Fig. 1) of the roll 55.

Slidingly mounted in a recess of the positioning frame I4 is a plunger 98 which, when there is no heel in the machine, is forced to its lower position by a spring I 80 (Fig. 2), downward movement of the plunger being limited by the engagement of a cotter pin I02 carried by the plunger with'the positioning frame. As the frame I4 forces the heel toward the abutment 'II] the plunger 98 is forced with yielding pressure against the forwardly projecting portion of the breast of the heel thereby insuring that the oriented heel shall be forced and held with considerable pressure against the table 68. g

The table 53 is supported by a bell-crank lever I04 which is mounted upon a pivot pin I05 secured by screws I08 (only one of which is shown)) in bosses III), respectively, of a circular base plate H2. The axis of the pivot pin I05 is parallel to the axis of rotation 84 of the cylindrical roll 58. The bell-crank lever I04 is constantly urged in a counterclockwise direction, as viewed in Fig. 2, to move the heel carrier 52 and the plate 50 to their inoperative positions away from the rotary abrasive tool 65 and the stop 6E, respectively, by the following mechanism. Pivoted to the horizontal arm of the bellcrank lever IE4 is a rod I I4 which passes through a recess H5 (Fig. 2) in a rearward extension II8 of a normally stationary, but adjustable, bracket I supported at the opposite ends of the pivot rod I56. Encircling the rod II t, and located between a nut I22 carried by the rod and the rearward extension II8 of the bracket I20, is a spring I24 which normally forces a shoulder I26 of the rod against the rearward extension H8. The bell-crank lever Ififl can be swung about the pivot pin IIIS against the action of the spring IZ I under pressure of the shoe against the plate 56, thereby forcing the lip 32 of the heel 34 mounted upon the carrier 62 (Fig. 1) against the rotary abrading tool 56, as above described.

As above noted, the lip 32 of the heel 34 is arched heightwise of the heel, as best shown in Fig. 5, and accordingly when the heel upon the carrier 62 is swung about the pivot pin I65 against a portion of the rotary abrading tool 66 located below a horizontal plane I28 (Fig. 2) passing through the axis of the tool, the lip of the heel, which lip includes the excess portion of the heel shown by dash lines (Figs. 5 and 6), is reduced to provide a lip the forward edge 56 (Fig. 6) of which is concaved. It will be noted that the depth 48 of the concavity of the front edge 48 of the lip 32 may be varied by raising or lowering the path of travel of the heel carrier 62, the depth of the above-mentioned concavity in the front edge of the lip increasing as the arcuate path of movement of the heel is lowered with relation to the rotary abrading tool 65. In order to present the heel differently to the rotary abracling tool 55 when removing material from the lip of the heel, to produce the desired depth 48 (Fig. 6) of concavity in the front edge 46 of the lip 32, the heel carrier 52 (Fig. 1) may be raised or lowered with relation to the bell-crank lever IM by mechanism which will now be described. A depending arm Hit of the table 68 fits in a guideway I32 of the bell-crank lever IIl I. into which is threaded a clamp screw I35 extending through a vertical slot I36 of the arm. In order to insure against any accidental downward displacement of the table 68 with relation to the bell-crank lever I64 there is provided a combined adjusting and thrust screw I38 which is threaded into a lu I40 of the bell-crank lever I84 and has its upper end in engagement with the lower face of the depending arm I36 of the table.

The cylindrical roll 56 is ro-tatably mounted upon a shaft I42 supported by the bracket I20 which, as above described, is mounted upon opposite ends of the pivot pin I56. The cylindrical roll 58 (Fig. 1) for driving the abrading belt 54 isassecured to a shaft I44 of an electric motor I In order that the abrading belt 54 shall'run smoothly upon the roll56 the shaft I42 is adjustable about a stud I48 which fits in an opening of the circular base plate H2 and is secured by a set screw l50 (Fig. 2) to the bed 52 of the machine. The base plate H2 is provided with one or more arcuate slots I54 which are centered about theaxis of the stud I48 and through which pass clamp screws I55 threaded into the bed I52. In order to facilitate turning the circular base plate II2 about the axis of the stud M8 so as to aline the roll 55 properly, the plate has an extension I58 which is engaged by an adjusting screw Iilil threaded into a lug I52 extending upwardly from the bed I52. The operator, after loosening the clamp screws I55, forces the adjusting screw I60 against the extension I53 of the circular base plate II2, rotating the same about the axis of the stud Hi8 until the roll56 is'properly positioned. The clamp screws I55 are then turned to secure the plate I52 against movement on the bed I52 of the machine.

Ihe bracket I2II may be swung in a clockwise direction, as viewed in Fig. 2, preparatory to removing the abrading belt 54 from the rolls 55, 58 by turning in a counterclockwise direction, as viewed from above, a screw IE4 which is threaded into the rearward extension II8 (Fig. 2) of the bracket I20 and has its lower end held by a spring IE6, against an abutment I58 of the base plate I IZ. When the abrading belt 54 has been mounted upon the

rolls

56, 58 the screw I64 is turned in a clockwise direction, as viewed from above, to swing the bracket I20 in a counterclockwise direction, as viewed inFig. 2, thereby tightening the belt. By swinging the shoe stop 59, together with the bracket I20 which carries the pivot pin I42 upon which the roll 56 is mounted, it is unnecessary to adjust the stop with reference to the bracket after the new belt has been placed in the machine.

The median portion of the lower face of the plate 59 has a cavity III) (Fig. 2) for accommodating the heel seat of the shoe, the transverse curvature of the front edge 52 of the plate, as

viewedin plan (Fig. 3), corresponding generally to the transverse curvature of the front edge M5 (Fig. 6) of the lip of the heel. It will be appreciated that the plate .50 may be replaced by any one of a plurality of plates the respective lower faces and front edges of which are of different shapes.

In order to assist the operator in holding the shoe against the lower face of the plate 5!] as the shoe is moved rearwardly against the stop 65 there is provideda shoe support In which is mounted upon a pivot pin I74 carried by the bracket I26 and is normally urged to a raised position by a spring I'Ifi. In presenting the shoe which the shoe is mounted against the support 72, depressing the same as he moves the shoe rearward until the heel-breast receiving shoulder 28 of the sole of the shoe engages the front edge 52 of the plate 5d, the support being relied upon to force the shoe firmly against the lower face of the plate. The shoe 22 and the plate 58 are then swung rearwardly together until the rear end of the shoe adjacent to its heel seat 40 (Fig. 4) engages the stop Bil, thereby causing the heel upon the carrier 62 to be swung rearwardly into engagement with the abrading tool 66 which removes material from the lip 32 of the heel.

In the illustrated machine the heel-engaging face 72 of the abutment 1%] is approximately in alinement (Fig. 2) with the margins of the arched portion of the front edge 52 of the plate 50, and the shoe-engaging portion of the stop 66 is approximately in alinement with the portions of the rotary abrading tool 86 engaged by the lateral margins of the lip 32 of the heel. With such an arrangement it will be clear that the length of the attaching face of the heel reduced by the machine will be approximately equal to the distance between the heel-breast receiving shoulder and the rear end of the heel seat of the shoe. As above stated, the face 12 of the abutment 18 may be quickly alined with the front edge 52 of the plate 56 by the above-v described mechanism.

It will be apparent that when the table 68 is raised or lowered upon the bell-crank lever M34, as above described, to present the heel differently to the rotary abrading tool 56, it will be desirable to adjust the stop 68 with relation to the bracket I29 so that the shoe-engaging portion of the stop shall be substantially in alinement with the portion of the tool engage-d by the lateral margins of the lip 32 of the heel. Accordingly, in order to secure the stop (it! in different adjusted positions upon the bracket I20 the stop is provided with a tongue I78 which fits in a, horizontal groove of the bracket, and an elongated slot l86 for receiving a clamp screw (82 which is threaded into the bracket.
