22 Claims.

This invention relates to the manufacture of shoes and is illustrated as embodied in a heelseat fitting machine.

When soles are fitted for the reception of wood heels prior to the attachment of such soles to shoe uppers, considerable difiiculty has been experienced in locating accurately the heel-breast line of the sole. Accordingly, when the heelseat portions of the soles are reduced before the soles are attached it is sometimes the practice to form a tongue shaped to receive the attaching face of a Louis heel and to leave tabs at the opposite lateral portions of the base of the tongue. Then, after the sole has been attached to the shoe, a hand operator trims the tab to form heel-breast-receiving shoulders against which the forward edge of the lip of the breast of the positioned heel abuts; or the tabs are skived to provide a pair of tabs such as are disclosed in United States Letters Patent No. 1,702,- 382, granted February 19, 1929 on an application filed in the name of Henry B. Gorman. The skived tabs are laid on the projecting lip of a Louis heel after it has been secured in position 7' upon the shoe, after which the heel-breast-covering flap is cemented to the breast of the heel. By trimming the attached sole, as above described, the hand operator is able quickly to complete the heel-seat-fitting operation after the sole has been attached to the shoe and the expense of such operation is materially reduced.

It is an object of this invention to provide an inexpensive machine which will quickly and effectively prepare the heel ends of unattached Another object of the present invention is to provide a machine which will form on an unattached sole, a tongue shaped to fit the attaching face of a Louis heel and a pair of tabs, which after the sole has been attached to the shoe, may be either trimmed to abut against the lip of the heel or may be skived to overlap such lip as above described.

With the above objects in view the illustrated machine, in accordance with a feature of the invention, is provided with members constructed and arranged to engage the opposite sides respectiveiy of a positioned sole and mounted for relative movement to distort the heel seat portion of the sole, and a cutter or die having heel seat reducing and shoulder forming cutting edges, the die being movable in a path disposed at a substantial angle to the plane of the sole to reduce the heel seat portion of the sole and to form heel breast receiving shoulders upon the sole.

' The illustrated sole-distorting members are of concave and convex form, respectively, and cooperate eiiectively to flex or distort and to clamp the heel end of the sole preparatory to severing the same. Theheel seat reducing edge of the illustrated cutter or die is U-sha'ped and cooperates with a correspondingly shaped shearing edge formed on the convex distorting member to trim the margin of the heel end of the sole by a beveling cut, and the shoulder forming edges which extend laterally from opposite sides of the U-shaped cutting edge are inclined to the plane of such edge and are constructed and arranged to cooperate with notches formed in the convex distorting member thereby to sever from the sole the portion cut by the U-shaped cutting edge.

With the above and other objects and features in view, the invention will now be described with reference to the accompanying drawings and pointed out in the claims.

The illustrated machine isdescribed with reference to the fitting of heel seats of unattached soles for the reception of Cuban and Louis heels.- In preparing shoes for the reception of Louis heels it is sometimes the practice, as disclosed in the above-mentioned United States Letters Patent No. 1,702,382, to trim the margins of the rear end of a sole 18 to provide a tongueportion 20 (Fig. 6) and to form at the base of the tongue a pair of tabs 22. After the sole 18, which has been trimmed in the machine, has been attached to the shoe, an operator accurately determines the position of the breast line 24 of the sole by placing a Louis heel on the shoe and either skives the tabs widthwise and lengthwise by the use of a hand knife and lays such tabs upon the breast of the heel or cuts off the tabs 22 (Fig. 7) to form, heel-breast-receiving. shoulders26 against which the fiorward'. edge of the lip of; the heel abuts.

In order to form the tongue 20 and the tabs 22 in the illustrated machine, the sole is placedflesh side downwardly upon a work-supporting table 28 the rear portion of the sole overlying an opening 30 (Fig. 1) formed in the table. The sole 18 is positioned upon. the table 28, rela tively to a convex member or block 32. around which the heel end of the sole is flexed or wrapped by a concave member 34 preparatory to moving a die 36 into engagement with the convex member 32 to trim the margin of the heel end of thesolaby a back gage 38. (Figs. 1 and 2) shaped and. arranged to engage the rear end of the sole. Theback gage38- comprises a forward cylindrical surface 40 having acurvature corresponding general-ly to the rear part of the heel. end of the sole and is provided with apa-ir of slots 42 shaped to receive upstanding. pins 44, respectively, carried bythe table 28;, which pins guide the gage 38 for purposes of, adjustment lengthwise of the table... The back gage 38 is also provided with. a central slot 46 through which passes a threaded pin: 48 securedto the table and constructed to receive a wing nut 50 of suitable size to clampthe gage 38, after it. has been: properly adjusted, to the table 28. When the rearend of the sole engages. the cylindrical surface 40 the sole is accurately positioned lengthwise and the rear end of; the sole,- is positioned widthwise.

To insure that the sole is properly positioned widthwise: upon the table. 28, a plate 52,. which is adjustable relatively to the table through the use:- of. screw and. slot connection 54, is mounted upon the table and is arranged to engage a side or. the sole immediately ahead of. the breast line 24:01 the same. To, assist the operator in readily setting the back gage 38. lengthwise of the table to accommodate different lengths: of soles such gage is provided with a mark 56 which may be placedinregistrywith oneof a plurality of index marks: 58; cut the sole-supporting face of the table:28-..

The: table 281 is mounted. upon four rods 60 secured to a stationary frame 62 to which the con,- vex. member 32 is: attached-., The block 32 comprises. a convex surface or dome portion. 64 from. the.- lower end of which extends a step- 66;. The

step 66 includes a. shearing edge 68 and is: constructed and arranged-for engagement with. the

lower corner 69- (Fig-.. 1-) of the concave member 34 when a sole is not. pnsitioned in the machine and the die ismoved. to a lowered position. The step 66-. also comprisesa; vertically disposed face 72. along which. a l-.l.-shap.ed: cutting edge 74 of the die 36 moves-to: trim, by a. shearing cut, solematerial clamped betweenthe convex: and concarvev members 32 and; 34. The; dome portion 64 of the block 32 has the. general fcrm of an ellipsoid. and, as above stated, cooperates with a concave or dished. surface 76.- (Fig. 1) of the member 3.4 110s depress the margin of the heel end of the sole with respect to the central portion of. the. heel end as themember 34is-moved down-- wardly with the. die.

The die 36 is provided withia laterally projecting plate; portion! '78; bored to. receive a pair of bushings constructed and arranged respectively to receive a pair of die-guiding rods 82 which are secured to the stationary frame 62.

The die 36 is also provided with a pair of opposed wing portions 84, the cutting edges 86 of which extend laterally of and downwardly from the L-J-shaped, cutting edge 74 and are spaced from the ends of the cutting edge '74. The cutting edges 36 are so arranaged that upon downward movement of the die 36 they engage notches 88 of the convex block 32 and form the tab 22 at each side of the tongue and remove the chip cut by the U-shaped cutting edge 74 from the sole.

The concave member 34, which is included within the U shaped cutting edge '74 and is mounted, for sliding movement relatively to the die 36 alcng a guideway 90 of the die, is secured to pins 92 movable along a cylindrical recess formed. in the die 36 and provided with heads 94 (Fig. 4) which limit the downward movement of the concave member 34 relatively to the die 36. Springs 96 surrounding the pins: 92 and the upper and lower ends of each of which engage the die 3.6.and. the concave member 34, respectively, normally forcethe concave distorting member downwardly relatively to the die 36 until the heads 94, engage a shoulder 98 of the die.

It. will: be noted. that When the die 36 is in its raised. position (Fig. 1) the concave member 34 projects slightly below the u-shaped cutting edge 14. 36.nis. lowered, the concave member 34 will cooperate with the dome portion 64 of the convex block. 32: effectively to distort the rear portion of the sole before the cutting edge 74 of the die 36 which operates in shearing relation with the edge 68" of the block 32 andv which slides along the; vertical face 72, of the. block, trims the marginal portion of the sole.

In; order to. cut. the. chip die 36 in two: parts so that material removedfrom thesole will readily drop from the machine at the end-trimming operation, the illustrated die 36 is provided with a cutting edge 100- which projects downwardly andrearwardly from the rear of the cutting. edge 74 and cooperates with a rear notch. 102 (Fig. 1) formed at the back of the convex block321 to cut the chip in half.

The die 36 may be reciprocated. along the rods 82'. by any suitable device, such for example as.

the treadl'eoperated mechanism disclosed. in United. States Letters Patent No. 1,697,243, granted January 1, 1.929 on an application filed in the name of. Jonas or. by any other suitable press.

The table 28 may be secured to or may be sliding-1y mounted upon the rods 60. When the table is slidingly mounted upon the rods 60 it is supported and is normally held inv a raised. posi tion by springs 104- which surround the rods.

The springs 1-04 permit the table 28 to be depressed as the sole is being operated upon to relieve the strain upon the sole in the vicinity of the breast line of the same during the sole-distorting and trimming operation.

In operating upon soles which are to receive Cuban heels it is desirable that hee1-breast-r-- ceiving shoulders be formed at the forward end of the. U-shaped cut made by the die '74 in order that the forward end of the U.shaped out, which in. the case. of Cuban work is not covered by a breast flap as in Louis work, will not be visible in the finished shoe. The illustrated machine may be slightly modified, as illustrated in Fig. 5, in order effectively to. trim the heel seats of soles It will, therefore, be clear that when the diev formed by the U-shapedfor the reception of Cuban heels. Such a machine is similar to that above described but is provided with cutting edges 106 extending laterally of and downwardly from the forward ends of the U-shaped cutting edge 74 and shaped and arranged to cooperate with notches 108 of the convex block 32 to form heel-breast-receiving shoulders upon the sole.

In order to perform the sole-trimming operation the operator positions the sole 18, flesh side down and breast flap 21 turned back, upon the table 28 by the use of gages 38 and 52. The die 36, which is normally held in a raised position is then caused to move downwardly whereupon the concave member 34 cooperates with the dome portion 34 of the block 32 to fiex the rear end of the sole as shown in Fig. 3. Upon continued downward movement of the die 36 the U-shaped cutting edge '74, which slides in contact with the face 72 of the concave block, severs the margin of the rear part of the sole by a beveling out. As the U-shaped cutting edge 74 moves past the U-shaped shearing edge 68 the cutting edges 86 enter the notches 88 respectively, to remove portions of the chip from the sole and to form the tabs 22.

The shape of the notches 88 and 108 may be such that the cutting edges 86 and 106 respectively of the die do not actually strike against the block 32 but sever sole material which is supported at opposite sides of the notches. Such an arrangement preserves the cutting edges 86 and 106 of the dies.
