BRUNO IVESSELMANN, OF GUTTINGEN, GERMANY.

METAL-SHEARING MACHINE.

SPECIFICATION forming part of Letters Patent No. 600,466, dated March 8, 1898.

Application filed October '7, 1897.

To (LZZ whom it may concern:

Be it known that I, BRUNO "WEssnLMANN, a subject of the King of Prussia, Emperor of Germany, residing at Gottingen, 5a Friedlander Weg, in the Province of Hanover, Kingdom of Prussia, Germany, have invented new and useful Improvements in MetaLShearing Machines, of which the following is a specification.

The subject of the present invention is a metal-shearing machine in which the main surfaces of the blades do not lie in one and the same plane, the blade in the lower shearin g-limb being set horizontally or nearly horizontally to the upper movable blade.

The invention further embraces the arrangement in the lower limb of two blades, each having two cutting edges, said blades either lying adjustably one upon the other or being fixed in a reversible limb or bearer, so that on using the shears, by simple turning of the blades lying one upon the other or of the reversible limb or bearer, four separate cutting edges can be brought to work.

On the accompanying drawings the new shearing-machine is shown constructed according to the methods above indicated.

Figure 1 is a front view, and Fig. 2 a plan view, of the shearing-machine having two blades lying one upon the other in the lower limb. Fig. 3 is a longitudinal section on the line a as, and Fig. 4. a cross-section on the line y y, Fig. 2. Fig. 5 shows a front View of the shearing-machine with reversible lower limb. Fig. 6 is a vertical section on the line 2 a, Fig. 5; and Fig. 7 is a plan view.

a and a are the reversible lower shearingblades; b, the upper blade, moved by a lever in or other suitable means.

In the construction. shown in Figs. 1 to 4 the two horizontal blades a and aare so arranged one above the other that they may be adjusted relatively to one another, and also by sliding in the lower limb c relatively to the movable blade. The fixing-screws d, Fig. 1, d 61, Figs. 2 to 4, of the blades for this purpose fit tightly in the blade a, while in the other blade a there is a slot (1 to receive the fixing-screws, this blade being therefore adjustable. 111 the under limb 0 there is a slot (Z to receive each fixing-screw d or cl, so that by means of the set-screws f adjustment of Serial No. 654,444. (No model.)

and 7 the same object is attained by fixing the horizontal blades (6 a in a lower limb or carrier 0, which may be reversed in its posi' tion in the framing of the shearing-machine. In this manner the four cutting edges of the blades, without being themselves removed from their bed, by a reversal of the latter may be adjusted relatively to the upper blade and be applied in shearing. In the machine here shown the framing is constructed of two lateral standards 9 g, forming the bearings for longitudinal bars It. On the two uppermost of these are centered the blade 11 and the downwardly-operating lever 70, while the two lower bars h carry the adjustable shearing-limb c. The reversal of the latter is effected either by drawing it from the bars 7L (when the ends of these at one side of the machine are free) or by taking the two halves of the limb apart.

The arrangement just described,Figs. 5 to I 7, is especially adapted for cutting strips of particular breadth from metal plates, since the upper blade, together with the lever, and the lower blade with bed can be adjusted at will on the longitudinal bars according to the breadth of the metal strips to be cutthat is to say, the distance of the blades 19 a from the right-hand standard g, which serves as abutment for the metal plate, can be adjusted to the breadth of strip required.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is-- 1. A metal-shearing machine having the blades arranged at an angle to one another,

in which, for the purpose of bringing four cutting edges into operation, there are two blades resting one upon the other and adjustable relatively to each other, so that according to the adjustment and reversal of the blades, each of the four cutting edges maybe brought into operation, all substantially as 3. A metal-shearing machine having the blades arranged at an angle to one another, 15 one of the blades being composed of two plates or sections a and a reversiloly arranged, said plates or sections being loose or detachable from one another so that each of said plates can have its edges set to the cutting line or edge, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

BRUNO WESSELMANN.
