2-9 Claims. (01. 51135) This invention relates to finishing machines and is herein illustrated as embodied in a heelbreast-scouring machine of the type utilizing a driven scouring belt which passes over a fixture 51 adapted to support the belt against the pressure of the work. In various of its aspects, however, the invention is not limited to machines provided with a finishing tool of the type above referred to.

One object of this invention is to provide a finishing machine having improved means for controlling the presentation of a work piece to a finishing tool. As herein illustrated and in accordance with a feature of the invention, a finish- 157 ing tool and a gage member are mounted for relative movement from an inoperative position wherein the gage holds the work piece out of con tact with the finishing tool during the presentation of the work piece to the gage member, to go; an operative position wherein the work piece is in engagement with the finishing tool. An advantage of this arrangement resides in the fact that the work piece can be presented to the gage member while the gage member and thefinishing tool 25. are in the inoperative position, thereby avoiding any finishing action upon the work piece during the preliminary positioningthereof relatively to the gage member and until the work piece has been properly positioned by the gage member with respect to the finishing tool. In the illustrated machine the gage is constructed and arranged for engagement with the breast surface of a heel to position the heel-breast surface in face-to-face relation to the operative surface of the finishing 315i tool, and a yieldable support is provided for the gage to enable the gage to move relatively to the finishing tool while maintaining the orientation of the gage and thereby of the heel as the heel-breast surface is moved against the operam tive surface of the finishing tool. A stop may conveniently be provided for determining the operative position of the gage with respect to the finishing tool. As illustrated, both the finishing tool andthe gage have their working surfaces curved to a form substantially complemental to that of the heel-breast to be treated. The finishing tool of the illustrated machine consists of a scouring belt supported against the pressure of the work by a form block shaped to impart the desired convex curvature to the scouring belt.

In accordance with another feature of the invention, a second gage, which extends transversely of the heel, is provided for substantially line contact with the tread surface of the heel to prevent transverse tilting of the heel while permitting the inclination of the heel to be varied in a direction which is heightwise and lengthwise of the heel. This second gage serves also to determine the heightwiseextent of the heel-breast surface to be presented to the finishing tool. A third gage may also be provided, as in the illustrated machine, for engaging the tread surface of the forepart of the shoe to insure accuracy in the angle of presentation of the heel-breast surface to the finishing tool.

l'he invention further consists in various features of construction and combinations of parts herein disclosed and claimed, the advantages of which will be apparent-to those skilled in the art from the foregoing description, reference being had to the accompanying drawings, in which Fig. lis a side elevation of the machine embodying the invention;

Fig. 5 is a perspective view showing an alternative form of theheel-positioning member.

The supporting structure of the machine consists of a standardlfl carrying at its upper end a hollow frame member 12 which supports the operative instrumentalities of the machine. Hinged cover plates Hand 16 provide access to the interior of the frame 12 at each end thereof respectively. The frame l2 houses an abrading belt 18 which passes over .a drive pulley 20, a pair of idler pulleys 22 and 24', respectively, and a form block 26. The drive pulley is mount.- ed upon the upper end of the vertically disposed shaft of a motor 28 carried by a bracket 30 which is supported by the standard 10 below the frame 12, and the upper end of this shaft extends within the frame 12. The drive of the motor 28 is controlled by a switch-29 positioned upon the forward end of the frame 12 and connected by a conduit 31 to a control box 33 mounted upon the standard 10, the control box 33 being connected to the motor 28 by a conduit 35. Beneath the motor 28 and also supported by the bracket 30 is a casing '32 having an exhaust blower. A rotary blower member within the casing 32 is driven by the lower end of the shaft of the motor 28. The suction created by the blower is com- 105 mun-icated to the interior of the housing 12 by a conduit 34 leading from the housing 12 to the inlet side of the blower casing 32. The dust which arises from the abrading action of the belt 18 upon the work will be conveyed by the draft 110 passing through the housing 12 and discharged through the exhaust end of the casing 32 into a dust-collecting conduit.

The idler pulley 22 (Fig. 2) is journaled in a bracket 36 which is mounted in the housing 12. The idler pulley 24 is journaled in a bracket 38 which is in the form of a bell crank pivotally mounted in the housing 12 upon a fulcrum pin 46. An arm 42 of the bracket 38 carries a short upstanding pin 44 which enters a groove 46 in a horizontally disposed screw 48 which is threaded in a boss formed in the side wall of the housing 12. The adjusting screw 48 is operated by a hand-wheel 50 through a clutch 52 comprising a pair of members having interengaging teeth which are so inclined as to slip when excessive resistance to the adjusting screw 48 is encountered. A spring 54 maintains the clutch members 52 yieldingly in operative engagement. The turning of the adjusting screw 48 to move the arm 42 towards the right, as viewed in Fig. 2, serves to move the pulley 24 to the left, thereby increasing the tension in the belt 18. The extent, however, to which the belt 18 may thus be tensioned is limited by the slipping of the clutch 52.

The form block 26 (Fig. 3) is carried by a bracket 56 which has an upstanding portion which is slidable in a vertical guideway formed in an upstanding portion 58 of the frame 12. A vertically disposed adjusting screw 60 is threaded into the upper end of the upstanding portion of the bracket 56 and has formed upon it a flange 62 which enters a slot 64 formed in the upstanding portion 58 of the frame. The vertical position of the screw 60 is determined by the engagement of the flange 62 with the slot 64 so that rotation of the screw 60 will effect an upward or downward adjustment of the bracket 56. The bracket 56 is clamped in its adjusted position by means of clamping screws 65 passing through vertically disposed slots 67 (Fig. 4) formed in the upwardly extending portion of the bracket 56 and threaded into the upwardly extending portion 58 of the frame 12. The form block 26 is slidably mounted between and supported by a pair of flanges 66 extending downwardly from a horizontal portion of the bracket 56, and an end plate 68 is secured to the rear ends of the flanges 66 by a pair of screws '70 and serves as a rearward stop for the form block 26. A binding screw 72 threaded into the horizontally extending portion of the bracket 56 engages the upper surface of the form block 26 and screws it firmly in position with respect to the bracket 56. The

form block 26 has a vertically disposed operative face '74 which is shaped to a curvature complemental to that of the desired contour of the breast surface of the heel to be scoured, and it provides a backing for the scouring belt 18 and to the securing belt 18. In order, however, to

insure that any heat generated by such friction will be rapidly dissipated, the form block 26 is the illustrated machine is composed of metal and is provided with a plurality of heat-radiating fins 80. In order to insure a contacting surface for the binding screw 72, a bridge member 82 extends crosswise of the fins 80.

A gage member 84 is provided for determining the position of a heel with reference to the plane of the tread surface of the heel relatively to the operative surface of the abrading belt 18 as it passes over the form block 26. The gage member 84 has a pair of operative surfaces 86 (Fig. 4) for engaging portions of a heel-breast surface of each side, respectively, of a heel, the surfaces 86 tapering as they approach the central portion of the heel-breast surface and each being formed to a curvature substantially complemental to the heel-breast surface which it is to engage. The gage member 84 has a central portion 88 which bridges the two operative portions and which is offset to avoid contact with the central portion of the heel-breast surface. An advantage of the tapered construction above described resides in the fact that in most instances the shank of the shoe intended to be operated upon is arched, and the work-engaging surfaces 86 may engage those portions of a heel-breast surface adjacent to the shank of a shoe and included between the surface of the shank and a plane which is tangent to the shank at its central portion. The gage member 84 thus leaves exposed for scouring action all that portion of the heel-breast surface which lies between the plane of tangency of the central portion of the shank and the tread surface of the heel. The gage member 84 is rigidly secured by screws 90 to the ends, respectively, of a pair of downwardly extending arms 92 of a yoke member 94 which is pivotally mounted upon fulcrum pins 96 mounted in cars 98 (Fig. 4) formed upon a cross-piece 100 (Fig. 3) which is rigidly secured by means of screws 102 upon the forward end of the bracket 56. Formed upon the cross-bar 100 is a rearwardly extending lug 104 which extends over the yoke member 94. Threaded into the lug 104 is a vertically disposed adjusting screw 106 which engages the upper surface of the yoke member 94 and thus limits the extent of rearward movement of the gage member 84, thereby determining the depth of the scouring action. Formed in the lug 104 is a boss 108 (Fig. 4) having a cylindrical bore in which is mounted a compression spring 110 which bears upon the upper surface of the yoke 94 and urges the gage 84 outwardly and away from the operative surface 74 of the form block. An adjusting screw 112 is threaded into the upper end of the boss 108 and acts through a disk or plunger to regulate the compression of the spring 110. Threaded into the yoke 94 is a vertically disposed adjusting screw 114 which bears against the upper surface of the forwardly extending portion of the bracket 56 and limits the outer movement of the gage member 84.

Rigidly secured upon the upper surface of the yoke 94 by means of screws 116 is a cross member 118 which carries a vertically disposed guideway 120. Mounted in the guideway 126 is a slide 122. A vertically disposed adjusting screw 124 is threaded through a lug 125 formed upon the upper end of the slide 122 and bears against the upper end of the guideway 120. The rotation of the adjusting screw 124 determines the position of vertical adjustment of the slide 122, and the slide 122 is then clamped in adjusted position by means of a binding screw 126 which is threaded through the slide 122 and bears against the guideway 120. Pivotally mounted upon a fulcrum pin 128 which is threaded in the slide 122 is a gage member 130 which has formed upon its lowerend across-bar 132 having its under surface formed to aconvex curvature. The fulcrum pin 128 is provided with a knurled head 134 rotation of which serves to advance the threaded portion of the pin 128 intothe slide 122 and thus to bind or clamp the gage member 130 in its operative position. An upwardly extending portion 136 of the gage member 130 chgages a lug 138 formed upon the slide 122 to determine the operative position of the gage 130.

When it is desired to remove or replace the form block 26, it is only necessary to turn the knurled head 134 sufiiciently to loosen the gage member 130 whereupon the latter may be swung upwardly out of the way.

A gage member comprising a plate 140 (Fig. 3) is mounted for universal movement by means of a ball-and-socket joint 142 upon the end of a downwardly extending adjusting screw 144 which is threaded through a boss 146 formed upon the upwardly extending portion 58 of the frame 12. A longitudinal slit 148 is formed in the boss 146, and a clamping screw 150 serves to tighten the boss 146 about the adjusting screw 144. A knurled head 152 is provided for turning the adjusting screw 144 to insure upward or downward movement of the gage member 140.

In the operation of the machine, a shoe S having a heel base H, as shown in Figs. 3 and 4, is presented to the gage member 34 which serves to hold the heel breast of the shoe S out of contact with the abrading belt 18 until the correct position of the heel breast, i. e., a face-to-face relation with respect to the operative portion of the scouring belt, has been established. The operative sur faces 86 of the gage member determine the angular position of the heel in substantially the plane of the tread surface of the heel, that is, a plane which extends lengthwise and widthwise of the heel. The gage member 84 thus orientates the heel in relation to the scouring tool. The gage member 132 serves to determine the heightwise position of the heel I-I, while the gage member 140, which engages the tread surface of the forward portion of the shoe S, acts in conjunction with the gage member 84 to determine the vertical and lengthwise inclination of the heel-breast surface with respect to the operative position of the abrading belt 18. In the operation illustrated in Figs. 3 and 4, substantially the entire heel breast excepting those portions engaged by the operative surface of the gage 84 is to be secured. The gage member 132 is, therefore, adjusted upwardly a distance suiiicient to permit the heel H to extend upwardly until the lower edge of the securing belt 18 is almost tangent to but out of contact with the shank portion of the shoe S. Such adjustment of the gage member 132 prevents marring of the shank by the lower edge of the scouring belt. In many instances, however, and particularly in the case of a heel provided with a rubber or composition top lift T, it is not necessary to scour a considerable portion of the heel breast but only the breast surface of the top lift T, and in such cases the gage 130 may be adjusted downwardly to insure that only the breast surface of the top lift T will overlap and come into engagement with the abrading belt 18. Assuming now the shoe S to have been presented to the

gages

84, 132 and 140, the operator presses upon the shoe, causing the gage 84 to yield rearwardly and bringing all portions of the surface to be scoured simultaneously into engagement with the scouring belt 18. The yielding of the gage member 84 allows the scouring action to proceed until the screw 196 prevents further yielding. The scouring action is then complete, and any further pressure upon theheel will be resisted by the gage member 84, which thus determines the position of the heel lengthwise of the heel with respect to the scouring belt. As previously'stated, the adjustment of the screw 106 determines the depth to which the heel breast can be scoured. In the case of heels provided with top lifts, the unfinished breast surface to the top lift usually extends slight beyond the breast surface of the heel base, and, when it is clesiredto finish the breast surface of the top lift only, the screw 106 may be so adjusted as to cause the finished breast surface of the top lift to be continuous with thebreastsurfaceoftheheelbase. It will be noted that, as the gage 84yields rearward ly from inoperative position, the gage member 130 moves with it so that there will be no relative movement between the tread surface of the top lift T and the cross-bar 132. An advantage in avoiding such relative movement resides in the fact that many top lifts are provided with irregu lar non-slipping tread surfaces, and, if such relative movement were permitted to occur, it might vary the relative vertical relation between the tread surface of the top lift T and the cross-bar 132. The convex under surface of the cross-bar 132 enables it to accommodate any angular position of the tread surface of the top lift T which may be imposed upon the shoe by the gage 146. It also serves to effect substantially line contact with the tread surface of the top lift T and thus avoids unnecessary contact with surface irregularities of the character above referred to. It will be noted that the gage 130 not only determine the heightwise position of the heel H but also prevents accidental transverse inclination of the shoe. other words, it serves to determine the position of the heel in a plane which is heightwise and trans verse of the shoe S. The gage 140 in conjunction with the gage member 130 serves to determine the angular position of the shoe in a plane which is vertical and longitudinal with respect to the shoe.

The machine, in the form above described, may also be used for the scouring of heels prior to their attachment to shoes. For work of this character, however, it may be more convenient to adopt the modification shown in Fig. 5, wherein the guideway 120 is removed and a guideway 220 is substituted therefor. A slide 222 is vertically movable in the guideway 220 and may be clamped in any desired position of vertical adjustment with respect thereto by means of a binding screw 224 which is threaded into a forwardly extending lug 226 of the slide 222 and which bears against the guideway 220. J ournaled upon a pin 228 which is carried by the upper portion of the slide 222 is a downwardly extending yoke member 236 having a pair of outwardly extending yoke arms 232 which carry trunnion pins 234 upon which is journaled a plate or work table 236. A gage 238 which may be calibrated in degrees is secured upon one of the arms 232 and enables the operator to adjust the plate 236 to obtain the desired angular relation between the heel-breast surface and the scouring belt. The trunnion pins 234 have their ends threaded into bosses 240 formed in the plate 236 and serve upon rotation to clamp the plate 236 in adjusted position. To prevent any swinging movement of the yoke member 94 about its trunnion pins 96, the screw 112 may beloosened, or

the screw 112 and the spring may be removed, and

the adjusting

screws

116 and 114 tightened to clamp the yoke member 94 in such a position that the edge of the plate 236 just clears the abrading belt 18. A gage 242 which is mounted upon the operative position of the work plate 236 facilitates the centering of the heel H and serves to hold the heel H against the sidewise drag of the scouring belt 18. When employing the work plate 236 for the securing of unattached heels, it is more convenient, as shown in Fig. 5, to rest the tread surface of the heel upon the work plate 236. When it is desired to remove and replace the form block 26, the yoke 230 may be swung upwardly by the plate 236. It may be secured in its operative position by a binding screw 244 which is threaded through a boss 2&6 formed in one side of the yoke member 230, the end of the binding screw bearing against the side of the lug 226.

It is evident from the foregoing description that the illustrated machine is not limited to operations upon complete heels but may be employed upon heel bases to which top lifts have not yet been applied, and also upon top lifts alone. The modified form of the machine shown in Fig. 5 can very conveniently be employed to scour top lifts alone. In the following claims, therefore, as well as elsewhere in the specification, the term heel is employed, for convenience, to denote not only a complete heel but a heel base or a top lift as well, and it is understood that the term heel is to be taken in this generic sense except where a more restricted meaning is necessarily implied by the context.
