MACHINE FOR USE IN THE MANUFACTURE OF COVERED HEELS Filed Feb. 27, 1928 Patented Aug. 16, 1932 UNITED STATES PATENT OFFICE WILLIAM H. NU'IT, or BEVERLYQMASSACHUSETTS, AssIeNoa r0 unrrnn snonum CHINERY CORPORATION, orrnrnnson, 'NEWJ'EBSEY, a CORPORATION or NEW JERSEY MACHINE FOR USE IN THE MANUFACTURE OF COVERED .HEELS Application filed l'sebruary 27, 1928. Serial No. 257,412.-

This invention relates to machines for use in the manufacture of covered heels and is illustrated as embodied in a machine for forming a groove, slot, or channel inthe breast of a heel block to receive inturned margins of a heel cover.

In United States Letters Patent No. 1,718,177, granted June 18, 1929, on an application filed in my name,- there is disclosed a wooden Cuban heel having a one-piece GOV-.- ering for its rear, side and breast surfaces, the end portions of the covering meeting at the middle ofthe breast of the heel and being tucked into a single straight and relatively narrow groove, slot, orchannel extending from the top to the bottom of the breast of the heel block. In order to insure uniformity and symmetry in the appearance, of the covered breast faces of heels of this type, it is desirable to form the groove exactly in the middle of the heel breast and to make the groove, straight and of uniform width and depth throughout its length. It is highly important also that the grooving operation shall be performed rapidly and without adding very considerably to the expense of making the heels; It is, accordingly, one object of the present invention to provide a machine bymeans of which wooden Cuban heels or other one-piece heels may be economically provided with accurately formed grooves, slots, or channels such as grooves formed as above stated and to this end there has been provided a novel organization comprising a cutter constructed andarranged to form in the breast of a heel a substantially straight and relatively narrow heel-cover-receiving groove or channel of considerable depth, and means for supporting the heel and locating it in predeter mined relation to the cutter, the cutter and the heel supporting and locating means being mounted for movement relatively to each other for performing the heel grooving operation.

In the illustrated machine the groove form? ing means comprises a power-driven circular saw. As illustrated, also, 'a saw table or carrier is associated with the saw, the table comprising a heel supporting slide which is guided for movement toward and from the saw so that a heel resting breast facedown upon the slide will have its breast surface grooved by the saw. The illustrated slide is provided with means for locating the heel so that-its breast surface will be centered transversely with respect to the saw and for clamping the heel after it has been located, and manually operablemechanism is provided for moving the slide.

The invention further consists in features of construction and. combinations of parts hereinafter described and claimed.

V In the accompanying drawing Fig. l is. a perspective view of a machine embodying the invention; and

The illustrated heel grooving machine comprises a base. 2 provided with bearings 4 for a horizontal shaft 6 to one end of which is fixed a circular saw. 8. The shaft 6 is adapted to be driven by a belt arranged to pass over fast and loose pulleys 10 and 12 on the shaft. A saw table or carrier 14 is located above the base 2 and in front of the saw. The table 14 comprises a stationary lower member 15 and a heel, supporting slide 24 which is mounted on'the table member 15. The table member 15 is supported by legs each consisting of a lower section 16 secured to the base 2 and an upper section 18 secured to the mem ber 15. f 'Theleg sections 16 and 18 are provided'with bolt and slot connections 20arranged to permit vertical adjustment of the saw table. For the purpose of thus adjusting the saw table 14 a plurality of thumb screws 22 are provided, the screws being threaded intosockets in the base 2 and arranged to engage the-lower surface of the table member 15. I

In order to form a heel-cover-receiving groove or channel G (Fig. 2) in the breast of a heel, the heel to be grooved, slotted, or channeled is fed past the saw 8 by means of the slide'24. As shown the slide 24 is mounted in ways 26 formed-in the portion 15 of the saw table so as to adapt the slide to move freely'in. directions at right angles to the axis of the saw. The slide 24 is slotted as shown at 28 to provide clearance for the saw. A handle 30 projecting upwardly from the slide 24 provides means for moving the slide. The range of movement of the slide is determined by the engagement of an abutment 32, adjustably secured to the slide, with a stop 34 fixed to the stationary lower portion' of the saw table. The slide 24 is adapted to support a heel by engagement 'with the breast face of the latter and provision is made for centering the heel relatively to the saw to insure that center of the" groove will coincide with the longitudinal centralgl-ine of the heel breast, and for clamping the heel tothe slide when it has been centered.

The means for centering a heel relatively to'the saw comprises two gages in the form of blocks 38 which are arranged at the forward end of the slide 24 at opposite sides of the slot 28. To enable the gage blocks 38 to be adjusted toward and from each other toaccommodate heels of different sizes the blocks, as shown, are provided with depending ears 40 which are received in slideways 42 in the slide 24. Adjustment of'the gage blocks is effected by means of rods 44 which are arranged to turn without longitudinal movement within bearings in the slide 24 and which have threaded engagement with the ears 40 on the gage blocks.

The means for clamping a heel to the slide 24 after the heel has been centered comprises a stationary but adjustable clamp member or abutment 48 adapted to engage the attaching face of a heel, and a movable clamp member 50 arranged to engage the bottom or top-liftreceiving face of the heel. The seat face engaging clamp 1nember'48 consists of a plate slotted at 52 to provide clearance .for the saw and having pivotal connections 54 with the slide 24. The clamp plate 48 is maintained rigidly in clamping position by means I of two braces 56 each of which is pivoted,

at one end of a rod 66 having a screw threaded connection with a slide bar 68 enabling the clamp member 50 to be adjusted toward and from the clamp plate 48 to accommodate different heights of heels. The slide'bar'68 rests upon a support 70 which is elevated above the plane of the slide'24 to avoid interference with the saw, the ends of the slide bar 68 extending through guideway's 72 secured to the support 70. The slide bar 68 is connected by a link 74 with a hand lever 76 by means of which the movable clamp member 50 may be manually operated. The hand lever 76 is pivoted at 7 8 to a block 80 and is secured by screws 82 to the slide 24. The screws 82 extend through the slot 84 in the block 80 permitting adjustment of the block and the pivoted screw 78 to compensate for adjustment of the movable clamp member 50.

In operation, after the centering blocks 38 and the clamp plate 48 have been adjusted to adapt them for use in centering and clamping a heel of a given size and shape, such as the Cuban heel shown in Fig. 2, the heel is placed, breast face down, upon the slide 24 between the centering blocks 38, 38 and between the clamp members 48 and 50 and the movable clamp member 50 is then moved into engagement with the heel by manipulation of the hand lever 76'. While retaining the lever 76 in position to maintain the heel clamped to the slide, theoperator, by means of the handle 30,1noves the slide rearwardly. thus moving the heel substantially parallel to the plane of movement of the saw in a straight path across the saw. The illustrated saw operates to cut in the heel breast a substantially straight narrow groove, slot, or channel G including at least two plane surfaces, the groove having uniform width, and considerable depth as well as having parallel sides as shown (Fig. 2). The heel being centered relatively to the saw, the groove will be centrally disposed transversely of the heel breast. By releasing the holding pressure exerted upon the hand lever 76, the heel may readily be removed from the slide 24' either before or after the slide has been returned to its normal position. After the slide has been returned and the grooved heel has been removed from the clamping means the device is ready for operation upon another heel. As before indicated, adjustment of the hand screws 22 determines the depth of the groove.

Although the illustrated machine has been described by reference to heel blocks it will be understood the machine may be used to form cover receiving slots or channels in the breast faces of heel blanks.
