In the 50 Figure 2 1S a VleW ln 51de @16173171011 0f the d1@ embodiments shown such connection is in the shown in Figure 1 part being in section to reveal foym Gf telesping members y and 3, Membgr the relation of the parts, and showing a shoe 'i may be provided with an internal spring (not upper in position for operation. shown) arranged to bias member il upwardly Figure 3 is a detail View taken from the rear relative to member l. While Figures 1 and 2 55 show the hinge connection only at the right hand rear corner of plate 6, it will be understood that an identical hinge connection is provided at the left hand rear corner thereof, as. shown in Figure 3.

In order to accomplish quick detachment and inter-change of plate 6, in accordance with the present invention, the member 8 may be arranged to readily release a cooperating hinge part carried by plate 6. In the embodiment shown in the drawing member 8 is of furcated structure with legs 9 and I0, the former leg being substantially shorter than the latter as shown clearly in Figure 3. Depending from plate 6 is a tenon member II arranged to t into the space between legs 9 and I@ of furcated member 8. The longer leg Ill of furcated member 3 is provided with a hinge pin I2 extending laterally therefrom and arranged to cooperate with an aperture i3 in tenon member I l. The position of hinge pin l2 is such that, in ordinary operation upon opening and closing plate E to an extent sufcient for the insertion and release of work parts, tenon member I I is retained between legs S and IQ of furcated member 8; when plate 5 is swung to an extreme position, however, as for instance, the position illustrated in dotted lines in Figure 2 tenon member II is then entirely above the shorter leg 9 and hence plate ii may be released from the hinge connection by sidewise translation thereof (to the right as seen in Figure 1) relative to base I until hinge pin I2 is withdrawn from aperture i3.

It will be observed that the hinge connection at the right-hand rear corner of plate 5, shown in Figure l, is` identical with the hinge connection at the left-hand rear corner, shown in Figure 3, sol that the shorter leg S is, in each instance, on the right-hand side (as viewed in Figure l) of the longer leg I6. However, it will be understood that the shorter legs might'be arranged on the opposite side of the longer legs, the side being immaterial provided both shorter legs are on the same side of their respective longer legs.

In the embodiment shown in the drawing, plate 6 is provided with a cut-out area Ili adjacent the cutting edges of die li, and is further provided with a gaging tip I5 whereby the Work, such as a shoe upper, may be properly aligned with reference to the die, as for instance, by coordinating gaging tip I5 with a line of stitching or other marks upon the shoe upper.

In the embodiment shown in the accompanying drawing plate 6 extends forwardly beyond die l and overlies a work support VI@ as clearly shown in Figure 2. Such a Work support i5 be in the form of a bight rod the ends of which are fitted into sockets in the base I, as shown at i6, and suitably secured therein, as for instance, by means of set Screw I2. Such a bight rod is shown in detail in Figure 4 and is provided with a central bight portion I9 the upper edge of which is at substantially the elevation of and aligned with the cutting edges 5 of die 4.

l/Vith the parts arranged in this manner the Work, such as a iitted shoe upper 2&3, may be draped over die d and work support i6, and adjusted until properly aligned with reference to gaging tip I5. Such an adjustment of the position or" upper 2l! may be readily accomplished by the operator who is gripping the upper Z between work support I S and the forward end of plate 6. The open center of portion iS of Work support I6 facilitates such adjustment and clamping since by gripping the assembly, as shown in Figure 2, the tip of one iinger is engaged with the lower surface upper 20 so that it may be moved to a limited extent without changing the position of the hand except to release the pinching grip upon plate 6 and work support I6. When the upper is properly positioned, the operator grips the upper between work support I6 and plate 6, and actuates a press to accomplish the cut-out or perforation.

From the foregoing description it will be apparent that the present invention accomplishes its object and provides a die wherein both the cutting element and the gaging device may be readily removed and inter-changed, and at the same time provides a die of such character that a iitted shoe upper may be draped over and effectively clamped to a work support while at all times the operator is enabled to make minor adjustment in the relation of the work to the die.

It is apparent that many modifications in the details and arrangements of part of the die herein disclosed Will present themselves to those skilled in the art without departing from the spirit of this invention. It is to be distinctly understood, therefore, that the embodiment shown in the accompanying drawing and hereinbefore described in detail is merely for the purpose of illustration and that 'the invention is not limited to such illustrative embodiment. It is therefore to be understood that such modications and the use of such individual features and sub-combinations of features as do not depart from the spirit of this invention are, although not specifically described herein, contemplated by and within the scope of the appended claims.
