EMBOSSING AND SHEARING MACHINE.

Application filed May 7, 1925.

T0 all whom` 'Zt may co'itcem Be it.known that I, IVILLIAM R. ECKE, residing at Emsworth, in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful Improvements in Embossing and Shearing Machines, of which improvements the following is a specification.

My invention relates to improvements in machinery for forming from an indefinite length of sheet material, ordinarily metal, a succession of duplicate plates of desired size and contour and bearing legible characters embossed upon them. Such plates have very extended use as labels for material of various sorts,-wire fencing. for example, fabricated and packaged for the market. The improvements in which my invention is found enable me to produce from the machine plates which are superior in the accuracy of their shaping and in the neatness and uniformity of their appearance.

Machines en'ibodying my invention are illustrated in the accompanying drawings. Fig. I is a View in longitudinal section of one such n'iachine` the plane of section being that indicated by the line I-I, Fig. II. TI is a View in transverse section, on the plane indicated at II-II, Fig. I. Fig. III is a view in horizontal section, on the plane indicated at III-III, Fig. I. Fig. IV is a dia grammatic view, showing in plan a strip of material which, under machine operation, is in course of fabrication into a succession of plates. F ig. V is a view corresponding to Fig. I and illustrating another machine which, differing in detail. still is an embodiment 0f my invention Fig VI is a view corresponding to Fig. IV, and illustrating fabrication in the machine of Fig. V.

Referring first to the machine of Figs. I-III, it includes a suitable bed or anvil 1 and a cooperating reciprocatory head 2. The bed carries a die block 3 and a shear block 4, spaced at a proper interval to achieve ends which will become plain as the description continues. The head carries a pressure block 5. A subepress is provided, which includes a reciprocatory head 6 carrying a shear block 7.

The die block 3 is adapted to receive and carry a collocation 31 of replaceable and in- Seral No. 28,605.

terchangeable embossing` dies. This ordinarily will be assembled in a chase andthe chase made removable and replaceable as an entity. The pressure block 5 which cooperates with the dies so carried to eliect the embossing of the sheet material is formed of suitable yielding material, suitably shaped. Ordinarily it is a plain-faced block of Wood.

The bed of the machine is shown to be recessed at Lll, to afford escape for so much of the material as is sheared away in the forming of the plates. The shear block 4 is perforate at 42, and the shear block 7 which cooperates with block 1l is equipped with columnar shear blades T2. Thus the shear in the embodiment presented has the character of a punch. A stripper plate 1:3 overhangs shear block t, as is usual in such machinery.

The reciprocatory head G of the sub-press is normally held by springs 6l in raised position; and, in addition, stops 62 may be provided, rising from bed l, to limit the head 6 in its upward range. The head 2 and the head 6 are so arranged that the head 2 on its down stroke abuts upon head G from above, and, pressing upon it from above, drives it downward in simultaneous stroke.

The shear members may take such particular shape as may be desired. Their shape in this particular instance is sufficiently indicated in Fig. III, and the consequent shape given to the sheared article is indicated in Fig. IV.

A strip of material a4 is carried, by suit able feed mechanism, not shown, in direction from right to left, as seen in Fig. I, and is intermittently brought to rest after advance through a definite and predetermined interval. The advance of the material and the descent of the head 2 are alternate, coordinated movements.

The material n, having been advanced to proper position above bed 1, comeslto rest. The head descends, and two operations are performed upon it: the Web of the strip, borne upon from above by pressure block 5, is embossed upon the embossing dies 31, and the advance end of the strip ,is sheared to shape. The head then rises, the material is fed forward through the predetermined interval and then stops again, and the head descends again. On the second descent one finished plate is sheared free, and a suc-
