WOOD HEEL MACHINE Filed June- 27. 1925 2 Sheets-Sheet 2 ArTo/PNEY Patented Feb. 14, 1933 PATENT FEQE WESLEY J. SHAW, F HAVERHILL, MASSACHUSETTS, ASSIGNOB, BY MESNE ASSIGN- MENTS, TO UNITED SHOE MACHINERY CORPORATION, OF PATEBSON, NEW JERSEY,

A CORPORATION OF NEW JERSEY WOOD-HEEL MACHINE Application filed June 27, 1925.

he present invention relates more particularly to machines for shank shaping Louis heels. Some features of the invention are, however, of more general application.

The nature and the objects of the invention will be better understood in connection with the accompanying drawings, in which Fig. 1 is a perspective view of a completed Louis heel; Fig. 2 is a side elevation of a machine constructed according to a preferred embodiment of the present invention; Fig. 3 is a plan of the same; Figs. 4 and 5 are sections taken upon the lines of Fig. 3 and 55 of Fig. 2, respectively, looking in the directions of the arrows; and F5 gs. 6 and 7 are, respectively, front and rear elevations of the same.

In the illustrated machine an alreadygrooved Louis heel blank (having its breast surface already formed, but having its shank lip straight on its under side), is turned past a shank shaping tool in a circular path about an axis lying beyond the attaching face of the blank, with the shank lip lying between the axis and the tool. This operation rounds the lower surface of the lip. The curvature of the lip surface formed is determined by the distances of the axis from the lip and tool, and these distances are adjustable, as will be seen.

A previously grooved wood-heel blank 2 is adapted to be clamped between lower and u )per 4 and 6 of a clamp 8. The heel blank is at this time provided with a projecting lip or shoulder 7, included between parallel, straight lines 9 and 11. A shaping tool 14, that is rotatable upon a horizontally disposed shaft 16, mounted on the machine frame 40, extends over a centrally disposed portion of the lip 7, and into the bottom portion of the breast groove 18 of the clamped blank when the latter occupies its normal, illustrated position. The clamp is actuated about a horizontally disposed pivot 10, to the I right and to the left of the said normal position, as viewed in Figs. 6 and 7, as indicated by the arrows. This may be done by means of a handle (not shown) or by merely grasping a portion of the clamp 8, as the arm por tion 86. The shoulder 7 becomes thus circu- Serial No. 39,954.

larly shaped by the cutter 14, on each side of the said centrally disposed portion, along the curved lines 20. 22. The blank is then removed from the clamp and another blank substituted. In order that the

curves

20, 22 may be symmetrically disposed, it is necessary to have the blank 2 centered between the

jaws

4 and 6, and this may be effected by using guiding fingers 24, 26., These guiding fingers automatically center the blank in proper position under the influence of a spring 12 which forces the fingers forward against the heel blank 2. The fingers and the clamp arm 86 are shown carried upon a common slide 13, between guides 15, so that the blank may be clamped and centered simultaneously. Theposition of the blank towards and from the cutter 14 is adjusted by means of an adjustable gage 28 that is engaged by the shoulder 7. The angular position of the blank may be adjusted to conform to the groove 18 in the heel by pivotally elevating the jaw 4 about a horizontally disposed pivot 30 that is perpendicular to, and positioned above, the pivot 10.

Provision is made for adjusting the pivot 10 vertically, or at right angles, to the lip 7, in order that its distance from the cutter 14, underneath which it is disposed, may be varied, in order to vary the radius of curvature of the lip surface formed. Such adjustment makes it possible to conform to the concave 18 in the heeland to gage the thickness of the shoulder or lip 7 This adjustment may be effected in any desired way. It is preferred to mount the pivot 10 in a bearing 32 provided at the upper end of a plate 34 that is vertically slidable between vertically disposed guides 36. The guides 36 are preferably integral with a bracket 38 that is horizontally adjustably secured to the frame 40 of the machine in any desired way, as by means of a pin-and-

slot connection

42, 44. The position of the bracket may thus be adjusted to and from the tool 14. The plate 34 may be vertically adjusted by means of a threaded member 46 that is threaded into the plate at 48 and that is held against vertical movement by a cross bar 50 on the bracket 38. The cross bar 50 is secured to the bracket 38 by screws or the like 52 and is provided with an opening 54 through which the member 46 extends and with respect to which it is rotatable. Collars 56 provided upon the threaded member -16, and between which the bar is confined, hold the member 46 against vertical movement. After the plate 84 has been vertically adjusted to the desired degree, it is clamped in adjusted position by a clamp screw or bolt 58 that extends through a vertically disposed opening 60 in the plate 34? and that may be threaded into the bracket 38.

In addition to adjusting the distance of the pivot 10 from the cutter 14, it is desirable to shorten and lengthen correspondingly the radius of the are described by the blank about this pivot and, therefore, the radius of curvature of the

curves

20, 22. To this end, the jaw 4 is pivoted at 30 to a plate 62 that is adjustable towards and from the pivot 10. This latter adjustment is effected by means of grooves 64, vertically disposed in the plate 62, within which are mounted tongues 66 provided upon a plate 68, which is pivoted to the plate 34 at 10. After the plate 62 has been moved farther from, or nearer to the pivot 10, by means of this tongue-and-groove arrangement, it is clamped to the plate 68 by a clamp bolt and nut 70 extending through vertically disposed openings 12 in the plate 62 and the plate 68.

The plate 62 is provided with a projection 74 in which is vertically threaded an adjusting screw 76, the free end of which engages the aw l. It is by means of this adjusting screw that the jaw a may be pivotally elevated about the pivot 30. The under portion of the l is provided with lugs 31, each having a horizontally disposed opening within which are slidably mounted rods 78. The gage 28 is carried at the ends of these rods. By sliding the rods '58 back and forth, therefore, the position of the gage 28 may be adjusted. Therods 78 may be clamped in adjusted position by nuts 84 or in any other desired manner.

In addition to the above-described adjustients, it is necessary also to make provision for the clamping of heel blanks of different sizes. This result may be attained by making one of the jaws adjustable. It is preferred to have the jaw 6 constituted of a clamping screw that is adj ustably mounted in the arm 86 of the clamp. The position of the screw upon the arm 86 determines the size of the blank that will be clamped.

In operating the machine the operator draws back the slide 13 against the spring 12, inserts the heel blank between the

fingers

24, 26, and then allows the spring 12 to force the blank forward against the stop 28, with its lip under the tool 14. He then swings the blank from side to side to enable the tool to round off the lip, as shown in Fi 1. The

thickness of the lip is controlled by the adjustment at 70, and the curvature of the lip by combined adjustments at 70, 58. In effect, in changing the curvature of the lip, the blank 2 and tool ll are kept together and the pivot 10 is raised or lowered on the slides at 64 and 36. Y
