Jufly H, 1933. J. F. STANDISH HOLDER FOR HEEL PORTIONS Filed Dec. 31, 1931 machine.

Patented July 11, 1933 UNITED STATES PATENT entice JOHN F. STANDISH, OF WINTHROP, MASSACHUSETTS, ASSIGNOR TO UNITED MACHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY Application filed December 31, 1931.

My invention relates to holders for such portions of heels as the top-llfts, 1t bemg chiefly concerned with the correct presentation of the lifts or other heel-portions to the nailing mechanism of a heel-attach1ng machine.

In the securing of heels to shoes, a machine much employed is of the character of that disclosed in Letters Patent of the United States No. 1,157,688, G-lidden, October 2t, 1915. In this apparatus, a swing-plate s movable alternately between opposite pos1- tions in which first a heel-base and then a top-lift are held to receive the actlon of the Ordinarily, the heel-portions have a conventional form, which allows them all to be properly grasped by the same retaining elements. There has come into use, however, especially in connect on with tapdancing, a form of heel 1n whlch a portion of the top-lift is replaced at the rear by a piece of metal, termed a clatter-plate. This may remove so much of the top-11ft that the top-lift-fork of the swing-plate or other heeland top-liftholder cannot effect stable epgagement with it nor correctly locate it Wlbll respect to the already attached base. To remove from the swing-plate the regular fork and substitute a special fork when but a limited number of the irregular lifts are to be attached imposes an objectionable burden upon the operator. A. purpose of the present invention is to provide for the satisfactory and convenient retention of these cut-away lifts, while permitting also the holding of the usual lifts.

This object I attain, in a holder for heelportions, by the use of two contact members, herein shown as forks, one of these members being effective to position one type of heelportion, as a top-lift, andthe othe anothep type of a similar heel-portion for attachmentto a corresponding work-surface, as the end of a heel-base. I employ a mounting for the second or auxiliary member, whlch permits its movement from the companion member to an inactive position away from the plane of the work-surface, or toward said companion member into active relatlon. The mounting of the auxiliary member 1s such HOLDER roa HEEL-PORTIONS Serial No. 584,162.

that the changing of the holder to receive a particular form of heel-portion which is to be operated upon may be accomplished with little effort on the part of the operator, with out adding elements to or removing them from the apparatus. In the arrangement which I have chosen to illustrate, the rear contact member or fork for the regular form of lift is fixed in position upon the holding plate for co-operation with the usual breastbar, and the auxiliary fork is movable into and out of co-operation with said bar.

- Preferably, the auxiliary fork and fixed fork are provided with engaging members, as in terlocking projections and depressions, by which the former fork is temporarily retained in active position. A slotted mounting for the pivot-pin of the auxiliary fork and a spring acting upon this pivot-pin facilitate the change and hold the engaged elements yieldably interlocked. 1 A single embodiment of the invention appears in the accompanying drawing, in which Fig. l is a top plan view of a swing-plate including my improved top-lift-holder;

Fig. 2, an enlarged perspective view of the top-lift-holder-portion of the plate, with the auxiliary fork in active position;

Fig. 3, a similar view, including fewer elements and with the auxiliary fork swung to its inactive position; and

Fig. 4, a bottom view of a heel with the partial lift and associated plate in place.

In Fig. 1 may be seen the cross-head 10 of the Glidden heel-attaching machine, already referred to,.with its die-block 12, in which are the driverand nail-passages 14c. -Pivoted atl6 to oscillate in a horizontal plane above the die-block is a: swing-plate l8 movable by connections 19 to first present a heel-holder 20 upon the swing-plate above thedie-hlock and then a top-lift-holder 21. The heel-holder includes no novel features and requires no description. f

. As to the toplift-holder 21, there is carried by the'swing-plate 18 a spanker-plate 22, and upon this is secured a fork 24, thearms of which have outwardly diverging surfaces 26, 26 for engagement with the opposite sidesof the curved rear of a top-lift, such as appears which may be associated a metal clatter-plate '29 (Fig. 4). The forward part of the lift 6 may be the same as that of the lift T, but the rear is cut away, having edges :0, 00 substantially parallel to the breast-edge, and a central projection y in the shape of a portion of a trefoil. Were this applied to the regular fork 24, the corners .2, a would contact with the arm- surfaces 26, 26. This would cause the top-lift to be held too far back with respect to the location in which it should be attached, and would tend to give unstable engagement. As a permanent attachment to the holder 21, I provide an auxiliary fork 34 for use with such top-lifts. This fork 34 is arranged to be positioned in front of the fork 24 and has diverging arms, like the fork 24, though these arms are so short that they do not extend to the lift-edges 00, w when these are pressed toward them by the breast-bar 28. Consequently, the curved opposite sides of the central lobe of the portion z engages edges 36, 36 of the fork 34, and the top-lift t is located thereby in the same manner as is the top-lift T by the fork 24. The active position of the fork 34 is sufliciently forward from the fork 24 toward the breast-bar, so the top-lift '25 will be symmetrically presented to the heelbase to which it is to be attached. To allow this auxiliary fork to be held in the correct active position just described and to be shifted therefrom to its inactive relation, leaving the fork 24 free for use, it is mounted in the following manner: Rising from a rearward extension 37 of the fork 24 are spaced lugs 38, 38, in which are openings 40, 4O elongated horizontally. Within these openings lies a pivot-pin 42 projecting from a dividedrear portion 44 of the fork 34. The center of the pin is joined by a tension-spring 46 to the rear of the extension 37. hen the fork 34 is in use, as appears in Fig. 2, the portion 44 is inclined downwardly and forwardly, and the fork-arms lie at such an angle thereto that they may rest upon the top of the spanker- .plate 22. In this respect, they'are positioned precisely as is the fork 24, but with their lift- engaging surfaces 36, 36 farther forward than the surfaces 26, 26, this being in prointo its inactive relation by drawing it forward sufficiently to release the projections from the depressions, the pin 42 traveling in the slots 40, and then turning this fork about the axis of the pin until it rests upon the swing-plate at the rear of the fork 24. This is as shown in Fig. 3. The force of the spring 46 holds it against accidental displacement.

Of the general operation of the heeland top-lift-holder of this invention, in connection with a heel-attaching machine, it may be said that, if a regular top-lift T is to be secured to a heel-base, the auxiliary fork 34 is turned rearwardly to the position illustrated in Fig. 3 of the drawing, being there firmly held by the spring 46. A. heelbase is inserted in the holder 20 and a toplift T in the holder 21, the heel-holder being in position above the die-block. With a shoe jacked in the usual manner and alined with the die-block-openings 14, the machine is started in operation, pressure is applied to the work, and the drivers rise to insert the nails through the heel into the heel-seat. This completes the attachment of the base. hen the jack rises, a force applied to the connections 19 shifts the swing-plate from the base-attaching relation to that shown in Fig. 1, in which the holder 21 positions the top-lift T above the die-block-openings. A second operation of the machine establishes pressure upon the work and causes it to force the lift upon the heads of the nails which were left, after the preceding operation, projecting from the base. The attachment of the heel with the regular lift is thus completed. Assuming now that a heel is to be provided with a clatter-plate p, as shown in Fig. 4, the auxiliary fork 34 is turned forward, as illustrated in Fig. 2, being drawn far enough in this direction for the projections 50 to clear the arms of the fork 24, these projections being then drawn back, under the influence of the spring 46, into the depressions 52. This locks the fork 34 in its active position. The top-lift t is applied to the spanker-plate between the breastbar 28 and the fork 34, the surfaces 36 of said fork engaging the sides of the rearward extension of the portion 'g of the lift to determine its position with relation to the die-blockopenings. The arms of the fork 34 are too short to contact with the edges w of the toplift, and there is consequently no interference with the correct positioning of the lift. The base is inserted in its holder 20 as before. The nailing of the base and the spankingon of the top-lift t are carried on precisely as was explained in connection with the attachment of the top-lift T. The clatter-plate ;0 may be applied to the base in contact with the rear edge of the lift and nailed by an lndependent operation.
