2 Claims. (01. 101--28) This invention relates to a marker for use in marking sheet material, and particularly to marking or embossing plates for applying ornamental designs or patterns to shoe upper sections.

5 The principal object of the invention is to provide a marking plate which will mark two similar shoe upper sections at one and the same time with one and the same pattern or design.

In the accompanying drawing:

Fig. l is a plan view of a double marking plate embodying the invention;

Fig. 2 is an enlarged detail in section on line 22 of Fig, 1; and

Fig. 3 is a side elevation of certain elements 016 a press illustrating the mode of use of the double marking plate.

The marker is made of a thin plate of metal 4, cut out to conform to the shape of the shoe upper sections to be marked. Although a plate for marking side sections of a shoeupper is shown in Fig. 1, it will be understood that this is merely by way of illustration and that the plate may be made in the shape of the vamp, cap, top or any other shoe upper section or piece which it is desired to mark.

The pattern which it is desired to apply to the shoe upper section is indicated generally at 5. It will be understood of course that the pattern may be varied according to the wishes of the de- 3 signer. The pattern is formed by bending or stamping from the plate 4 a number of marking projections 6 and 7 by means of a die and punch. The projections are of generally conical or tapered form and are substantially uniformly spaced apart and arranged in lines or rows to delineate the desired pattern. The marking projections 6, 6, project from one side of the plate, and the marking projections 7, 7, project from the opposite side of the plate. The projections at one side of the plate alternate with the projections at the opposite side of the plate, each projection on one side being formed from the metal of the space between two projections on the opposite side, and being preferably located 45, substantially in the middle of such space. Thus the marking projections on the two sides of the plate are located in a common row or line on the plate, the line of projections on one side registering with the line of projections on the other v side. The pattern will therefore be alike on both sides (although reversed) and the forces applied to the projections, when under pressure acting from opposite directions in the marking operation, will be in the same line, common to the two sets or projections, thus avoiding any tendency to warp or distort the plate, which might result if the projections on one side were offset out of alignment with the projections on the other side.

The double marker is used as illustrated, more or less diagrammatically, in Fig. 3, wherein 8 represents the work bed of a press of any suitable form, and 9 represents the plunger, the under side of which is preferably lined with a resilient pad 10 of rubber or any suitable cushioning material. A transfer sheet 11, which may be a sheet of coated transfer paper similar to carbon paper, is laid coated side up on top of the work bed 8. Next to the transfer sheet is one ofthe shoe upper sections 12; next above that is the marking plate 4; and next above that the other shoe upper section 13. Assuming that the shoe upper sections are of leather the section 12 at the bottom is preferably placed grain side against the transfer sheet and back side against the marker; and the shoe upper section 13 at the top is placed grain side against the marker. Thus in each case the grain side is marked, the bottom section 12 by the transfer sheet and the top section 13 by the direct impression of the marking 30 projections. Or, instead of the procedure just described, the transfer sheet may be omitted, in which case the bottom section 12 should be placed rain side up in contact with the marker, so that both pieces will be marked by the direct impression of the marking projections. In all cases the two shoe upper sections and the marking plate should be arranged in accurate registration with one another to insure accurate positioning of the corresponding patterns on the two sections. 90, When the parts are properly assembled in the press, the plunger 19 is brought down on top of section 13 and the pattern of the marker is applied to the two sections 12 and 13 by pressure.

From the foregoing it will be seen that my new 95. marker makes it possible to mark two pieces simultaneously, thus greatly speeding up the work, and also makes it possible to mark a right and left section at one and the same time, with identical but reversed patterns which will be accu- 199 rately and symmetrically arranged on the two sections.

I claim:

1. A shoe upper marking device for simultaneously applying identical markings to each of a pair of shoe upper sections, said device comprising a sheet metal plate having on each side a set of struck-up projections defining predetermined patterns on both sides of the plate, the projections on one side of the plate alternating with rality of embossed portions alternately disposed relative to corresponding embossed portions on the opposite side of the plate, said embossed portions defining identical patterns in substantial registry on both sides of said plate.
