March 19, 1940. A. MADOW APPARATUS Fon OPERATING UPON HEELs Filed Feb. 9, 1938 Patented Mar. 19, 1940 APPARATUS FOR OPERATING UPON HEELS Abraham Madow, Brookline, Mass., assignor to United Shoe Machinery Corporation, Borough of Flemington, N. Jersey J., a corporation of New Application February 9, 1.938, Serial No. 189,555
Claims.
My invention relates to apparatus by which theremay be performed upon heels such an operation as that of sduaring, this involving the'production upon the periphery of a heel of a sur-l face, which,` considered at an intersecting horizontai plane, is bounded by a straight line, though curved vertically.
In squaring a heel, the usual practice is to subject the peripheral wall, as at the rear, to the action of a rotary abrading member, such as a scouring roll, which will remove the heel-material to the desired depthffrom a line extending transversely of the tread-surface to a point somewhat below the edge of the heel-cup and thereafter to nish-the surface upon another abrading member, as a buiing roll. It is convenient to perform these operations after the heel has been attached to a shoe. An object oi my invention is to effect the squaring of the heel quickly and accurately by means which is convenient for the operator to use and which may be adjusted readily to meet diierent work-conditions.
In the accomplishment of this object, l2 Combine with a roll having a scouring surface and a bufng surface a support or jack adapted to enter and hold a shoe for the presentation of the back of its heelto the abrading means and a mounting for the support comprising apair of spaced arms pivoted upon the frame and connected by a rod, the support 'being movable along and about the axis of the rod. The 'first movement is to determine the abrading section with which the work is-to contact forv scouring or bufng as desired, and the second permits such Contact. In the form of the invention herein disclosed, the rod is rotatable upon the mounting-arms, the' shoesupporting jack being splinecl tothe rod to move longitudinally of while turning with it. An arm is fast upon the rod for engagement with a stop which limits the depth to which the abrading actionymay take place.
In the accompanying drawing,
Fig. 1 is a top plan view of the apparatus;
Fig. 2j a side elevation looking from the right in Fig. 1;
Fig. a sectional detail of the connection between the jack and its carrier-rod, it being taken along the line III-III of Fig. 2. while Fig. i shows in perspective an example of the work performed by this apparatus.
At Ill appearsa portion of a machine-frame, with which is associated a support, appearing in the present instance as spaced brackets I2, l2 projecting horizontally from the frame. These brackets, with the elements they carry, may be (Cl. 51-'94) v adjusted together vertically by virtue of va slotand-screw connection It to the frame and elevating screws I6 threaded through frame-lugs and upon which the bracketsr rest. Rotatable v in bearings at the top ofthe frame is a horizontal shaft i8, upon which is fast an extended roll or cylinder 20. Side by' side upon the roll are abrading sections 22 and 2t, the rst of which may be coarse, while the second is relatively ne.
'Ihat is, the section 22 is adapted to rapidly reduce or scour work presented to it, while the section 24 will finish or bui the surface produced by the companion section. The circumference of lthe roll will be chosen to give the correct curvature to the surface vwhichthe sections produce. Said, roll may be rotated at the chosen speed by belt or other gearing 25. At the outer Vextremity of each bracket l2, a vertical plate 2E is secured, this having extending toward the abrading means, a slot 28, theA slots in the two plates beingv horizontally alined. Pivotally attached lto each plate -by a bolt passing through the slot is an arm 32, the inner end of which is held against lateral displacement-by a post 34, rising from the bracket and provided Witha vertical guide slot 3B through which the arm may be moved..v Each arm 32, at its lower edge, has an inwardv extension 38, so this portion of said arm is L-shaped in transverse section. In addition to stiifening the arm, the extension supports it for angular adjustment about the pivot-bolt 30. Rising from each bracket through a slot 39 in the corresponding arm-extension 38 is a post t@ threaded at its upper end. Washers 12,-42 encircle the post upon opposite sides of the extension. Between the bracket and the lower washer, a spring lid is interposed, this urging up the arm to a variable extent determined by the adjustment of a nut 46 upon the threaded end of the post. .By the means just indicated, the arms and the elements which they lcarry may be adjusted both bodily and angularly with respect to the roll 20.
Between the two arms 32, 32 is mounted a shoesupporting member or jack i3 arranged to hold a shoe with the tread surface of the heel substantially parallel to the axis of. the roll 2t. The jack 48 is carried by a rod 5 extending from arm to arm and being substantially parallel to the axis of the roll 26. This rod may, turn in bosses 52 projecting inwardly from the arms. It is held in the arms 32 against longitudinal displacement by the hub of an arm 5ft fast` upon one end of they rod and a collar 56 secured to the other, each of these elements contacting with the outer side of the adjacent arm. The direct mounting of the jack is furnished by a downward projection 58 from it, this terminating in a laterally extmiding sleeve 6E! slidable longitudinally of the rod but being compelled to turn with it by a connecting feather 62 movable in a spline 64 in the rod. This movement of the jack along the rod permits it to present work mounted upon it to either of the abrading surfaces 22, 24, while rotation of the rod and jack together allows the latter to be moved from a work-receiving position, spaced from the roll Zt, to an operating position in which the supported work may be subjected to the action of the abrading surfaces. The distance through which the jack may be moved in either direction is limited by one of two stop-screws G6 and 63, threaded through lugs upon one of the arms 32 and with which the arm 54 may Contact. When the arm is against the screw 56, the weight of the jack will hold it away from the abrading means, giving sucient space to place the work upon the jack without danger of contact with the surfaces 22, 2d. When the mounting is swung inwardly, the rod 5l! turning in its bearings, the work upon the jack may be brought into engagement with either of the abrading surfaces, and this caused to act to a depth approximately determined by the screw 68.
In using the apparatus, and with the arm 54 of the jack-mounting engaging the screw 66 and the jack El opposite the scouring surface 22 of the roll 28, the operator places the shoe, shown at S with its heel I-I, upon the jack, drawing the counter-portion of said shoe against the rear of the jack. The opposite extension of the jack at the rear and front of the mounting-projection 58, bearing against the interior of the shoe, gives an approximately correct transverse angular position for the work. The jack is then tipped forward, the rod 5D turning in the arms 32, until the back of the heel strikes the rotating surface 22. This will remove the heel-material, producing a depression transversely squared but curved vertically in a form determined by the circumference of the roll and having a depth which will not be greater than the limit xed by the engagement of the arm 54 with the stop-screw 68. Since the portion of the work operated upon is placed by its inverted position directly in the View of the operator, he is able to watch the action of the scouring surface and swing the jack away from the roll when approximately the desired depth has been attained. Then, the jack is carried to the left along the rod opposite the bufling surface 24 and again swung inwardly, so the area squared by the surface 22 may be smoothed. This buing action may continue, until the stop-screw 68 prevents further reduction. The work, having the finished form shown in Fig. 4, will be removed from the jack, which is shifted to the right ready for the presentation of another heel to the abrading surfaces. By a proper combination of adjustments of the arms 32 bodily toward and from the roll 20 by varying the pivot-points at 30 and angularly about the pivots under the influence Of the nut 46 and the spring 44, the relation which the produced surface a bears at b to the rear of the heel-cup and at c to the tread-surface may be varied Within the desired limits.
