BEAM-SHEAR.

Specification of Letters Patent.

duplication March 22 Serial N- 1'0 a whom it may concern:

Be it known that I, CLARENcE L. TAYLOR, of Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Beam-Shears and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in beam-shears, the object being to provide a machine designed to cut beams of various Widths; and it consists, broadly, of a laterally-adjustable cutter and laterally-adjustable side clamps for clamping the beam centrally below the cutter.

The invention further consists in the parts and combinations of parts, as will be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in vertical section of the machine. Fig. 2 is a similar view taken at right angles to Fig. 1 and Fig. 3 is a view in horizontal section taken on the line as a; of Fig. 1, the section of the housing at the left being taken on the line (1 y of Fig. 1.

1 represents a base of any suitable con struction and design, to which the housing of the shear is secured by bolts 2. This housing is preferably composed of two sides or

uprights

3 and 3 cast integral at their lower ends, and secured by bolts to the base 1. Seated on the upper ends of housing 3 of the frame is the inverted cylinder 4, the latter being secured in place by the bolts 5, which pass vertically through the

uprights

3 and 3 near the side edges of the latter and are secured at their lower ends near the lower ends of the housing by nuts 6, seated in sockets in said uprights. The bolts, as above stated, pass through openings formed in projections from the cylinder 4 and firmly secures the latter to the top of the housing, the inverted open center of the cylinder resting in the vertical center of the space between the side frames or sections of said housing.

Mounted in the cylinder 4 is the plunger 6, the latter being provided at its lower end with a cross-head 7, enlarged, as at 8, at its ends to form bearings, the said bearings resting and moving in the grooved ways 9, formed in the sides of the

housing

3 and 3 Mounted on the columns 10, resting on the cylinder 4 and secured to the latter by the bolts 11, is the cylinder 12, in which is mounted the plunger or piston 13, the latter being connected to the piston 6 by the rod 14, which latter passes through a gland in the top of the cylinder 6 and is secured to the piston or plunger 6 therein by any approved means. The function of this upper cylinder 12 and its plunger or piston 13 is to elevate the main plunger 6 and its attached shear or cutter after each cutting stroke.

The lower end of the plunger 6, or, rather, the cross-head 7, formed integral with said plunger, is provided on its front and rear faces with the grooves 16 to receive the upper ends of the clamps 17, which latter clamp the shear-head 18 to the cross-head 7 of the plunger 6. These clamps are shaped as shown in Fig. 2 and are secured to the crossh'ead of the plunger by the bolts 19 and engage the lower inclined surfaces of the shearhead 18, the inclined faces of the clamps and shear-head tending to hold the latter up solidly against the lower face of the crosshead 7, as clearly shown in Fig. 2. The lower face of the cross-head is provided centrally with a longitudinal rib 19, which rests within a corresponding groove in the shearhead for preventing the latter from being moved by the clamps out of the plane of the slot in the die-bed 20.

J ournaled in one bearing 8, depending from the cross-head 7, is the adjusting-screw 21. This screw is prevented from moving longitudinally by the collars 22 and engages a screw threaded opening formed in the shear-head near the top thereof. By means of this screw the shear can be adjusted so as to bring its centerdireotly over the center of the beam or girder to be cut. Each cutter or shear 23 may be provided with its own head, or the cutters or shears may be detachably secured to the head, so that one head may answer for several sizes of shears or cutters designed to be used with the machine. 'Ihese cutters or shears are, as shown in Fig. 1, provided With a centrally-located point 24, with the sides or cutting edges beveled from the point up.

The die-bed is carried by the housing and is clamped thereto, as shown in Fig. 2, by the clamps 25. This die-bed is provided with a slot 26 of sufficient length to receive the largest size shears or cutters used on the machine and is provided with the bottom dies 27 (shown in Fig. 2) separated just sufli cient for the passage of the shear or cutter.

Mounted in the die-bed at one end is the movable clamp 28. This clamp is slidingly mounted in a grooved slot in the die-bed and is provided with a swiveled adjustingscrew 29, which passes through a threaded opening in the die-bed. The inner end of this clamp 28 is provided with a vertical slot, as shown in Fig. 3, in which are secured the end dies 29, (see Fig. 3,) the end dies in this clamp and also the dies 29 in the clamp 30 at the opposite side being located in the vertical plane of the bottom dies. The clamp 30 is also slidingly mounted in the die-bed 20 and bears against the wedge-shaped end 31 of the plunger 32. The plunger 32 is mounted in the cylinder 33, carried on a shelf 34, integral with or secured to the housing, and its Wedge-shaped end 31 passes through a transverse opening 35, formed in the die-bed 20. The clamp 30 is secured to a bolt 36, which passes through an elongated slot 37 in the wedge-shaped end of the plunger 32 and through the die-bed 20 and is provided on its outer end with a nut 38', against which the spring 39 bears, the said. spring tending to always hold the clamp 30 against the wedgeblock 31, so that as the wedge is withdrawn the clamp 30 will be moved away from the girder.

In the operation of the machine the

clamps

28 and 30 are adjusted to receive the beams to be cut, and, if necessary, the blade or shear should also be adjusted and the die-bed moved longitudinally, if necessary, so as to bring the center of the clamped girder directly under the center of the shear or cutter 23. As shown in Fig. 1, the die-block has a rack cast in its bottom surface, the teeth of which do not project below this bottom surface. A gear 40 engages with this rack and is operated through the shaft shown by a hand-crank, which can be placed on the square end of shaft. By this means the block can be moved out from between the housings to a position convenient for lifting it with a crane. After the parts have been properly set for a certain size beam the clamp 30 is withdrawn by the withdrawal of the wedge-shaped end 31 of the plunger. This movement of clamp 30 leaves a space sufficiently large for the ready introduction of the beam. After the beam has been insorted and clamped the water or other fluid in cylinder 13 is exhausted and fluid under pressure is admitted into cylinder 4, which forces down the plunger 6 and causes the shear or cutter 23, assisted by the

dies

27 and 29, to sever the beam. After the latter has been severed the fluid in cylinder 4 is eX- hausted and fluid under pressure admitted to cylinder 12. This elevates the plunger 6 and its attached shear or cutter, after which the several parts of thebeam are released by the withdrawal of the clamp 30.

It is evident that many numerous slight changes might be made in the relative arrangement of the parts herein shown and described without departing from the spirit and scope of my invention. Hence I would have it understood that I do not wish to conline myself to the exact construction. and arrangement of parts shown and described; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
