MACHINE FOR CUTTING I-BEAMS OR CHANNEL-BARS.
SPECIFICATION forming part of Letters Patent No. 438,252, dated October 14, 1890.
Application iiled August 25, 1890. Serial No.363,022. (No model.)
VTo all whom t may concern:
Be it known that I, JOHN KOEHLER, a citizen of the United States, residing at Canton, in the county ot' Stark and State of Ohio, have invented certain new and useful Improvement-s in Machines for Cutting I-Beams or Channel-Bars or other Difficult Shapes; and I do hereby declare that the following is afull, clear, and exact description of the samle, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon, in which Figure 1 is a view of the blade-holding head, showing the same properly located-and the blades in position to cut the web of an I- beam or channel-bar, and also showing an I-beam properly located. Fig. 2 is an edge view of one of the cutting-blades. Fig. 3 is a detached View of the blade-holding link or key. Fig. 4 is a view illustrating the cuttingblades passed through -the web of an I-beam, said parts being shown in dotted lines. Fig. 5 is a View showing the parting-wedge down in position to part the cutting-blades, also showing the cutting-blades parted to cut the ilanges of an I-beam or channel-bar. Fig. 6 is a detached view of the wedge-block. Fig. 7 is a top lview of the bed-plate, showing the fixed or under dies properly located thereon and the same securely clamped. Fig. 8 is a view showing the fixed of under dies together with their dierent attachments detached. Fig.` 9 is a view showing an I-beam properly clamped and placed upon the bedplate, and the cutting-blades locked to the sliding head. Fig. l0 is a transverse section of one of the cutting-blades, showing the top or upper part of the blades full. Fig. 11 is a section through line, Fig. 1. Fig. l2 is an edge view of one of the clamping-links, showing the eccentric properly attached thereto.
The present invention has relation to machines calculated and designed to cut I-beams or channel-bars by means of dies; and it consists in the different parts and combination of parts hereinafter described, and particularly pointed out in the claims.
Similar letters of reference indicate corresponding parts in all the gures of the drawings.
In the accompanying drawings, A represents the blade-holding head, which is designed and calculated'to be moved up and down by a plunger operated by means of an eccentric or other mechanism commonly used to operate a reciprocating plunger in diepresses.
Within the head A are located the top orl upper portions of the cutting-blades B. These cutting-blades are each provided with the notch or groove a, which are for the purpose of receiving the ends of the key b, and when it is desired to have the cutting-blades B t'ollow the movement offthe head A the key b is placed in the position illustrated in Fig. 9, thereby locking the blades B to the head A.
For the purpose of providing a means to extend the key b into the notches or grooves a the openings c are provided.
To the barO are attached the bottom or lower web-dies D, which dies are so located and adjusted that they will come directly under or beneath the web of an I-beam or channel-bar. These dies D are set far enough apart to allow the cutting-blade B to pass down betweenv said dies D. i
To one end of the lower dies D is located the head E, which head is fixed to the bar C by means ot' seating a portion of said head E into the groove d, or in any other well-known and convenient manner.
To the head E are securely att-ached the flange-dies d.
To the opposite ends of the dies D is located the movable head F, which head is provided with the ange-dies d2.
For the purpose of securely clamping an I-beam or channel-bar between the heads E and F the links e are provided, which links receive the die-heads E and F, substantially as illustrated in Figs. 7 and l2, and for the purpose of binding the die-heads E and F against the outer faces of the ilanges designed to be cut the eccentric G is provided, which eccentric is held to the links e by means of the bar f and the collars f.
For` the purpose of operating the eccentric IOO should be set far enough away from the ends of the dies vD to allow the flanges of the I- beam or channel-bar to be received between the die-head E and the ends of the dies D.
In use the beam designed to be cutis placed in the position illustrated in Fig. 9, at which time the sliding head A is forced downward until the blades B have passed through the web of the I-beam or channel-bar and eX- tended to the bottom of the side flanges of the I-beam or channel-bar, at which time the key b is removed from the head A, thereby disengaging the cutting-blades B from the sliding head A, at which time vthe sliding head A is again elevated, thereby forming the opening H directly above the top or upper end of the parting-wedge H'. The block or bar I is placed through the opening I-I and on the top of the parting-wedge H' and the sliding head A again forced downward, carrying with it the parting-wedge H', and thereby expanding the cutting-blades B, as illustrated by the dotted lines, Fig. 5, which cause the cuttingblades B to pass through the flanges of the I-beam or channel-bar, after which the cutting-blades B and the parting-wedge H' are again placed in the position illustrated in Fig. l and the key b placed in the position illustrated in Fig. 9.
For the purpose of providing stops for the cutting-blades B the rollers g are provided, which rollers are placed through the apertures g' and roll or slide on the die-heads E and F, when the blades B are expanded by means of the parting-wedge H.
It will be understood that the inner edges of the cutting-blades B should be provided with a V-shaped groove h, which are for the purpose of receiving a V-shaped ridge upon the edges of the parting-wedge H', thereby preventing any accidental lateral displacement of the parting-wedge H.
For the purpose of assisting in holding and elevating the cutting-blades B the helical springs .I are provided and are attached in any well known and convenient manner to the pins h' and h2 or their equivalents.
In the drawings, K represents the bedplate, which is attached to the press-frame K' in the ordinary manner.
It will be understood that other means may be used for parting the cutting-blades B without departing from the nature of my invention.
I-laving fully described my invention, what I y claim as new, and desire to secure by Letters Patent, is-
l. The sliding heads A, havin glocated therein the cutting-blades B, the parting-wedge H', the fixed dies D, and the flange-dies d and d2, substantially as and for the purpose speciiied.
2. The combination of the heads A, the cutting-blades B, provided with the notch or groove a, the key d, and the parting-wedge H', substantially as and for the purpose specified.
3. The combination of the head A, having located therein and carrying the cuttingblades B, the dies D, d', and d2, and means for parting the cutting-blades B, substantially as and for the purpose set forth.
4. The head A, having located therein the cutting-blades B, the parting-wedge H', located between the cutting-blades B, and the block or bar I, substantially as and for the purpose set forth. l
5. The combination of the bar C, having attached thereto the dies D, the die-head E, fixed to the bar C, the movable head F, the links e, and the eccentric G, substantially as and for the purpose set forth.
6. The combination of the head A, the cutting-blades B, the stop-rollers g, the dies D, d', and d2, and means for clamping an I-beam or channel-bar, substantially as and for the purpose specified.
7. A device for cutting I-beams, channelbars, or other difficult shapes in which the central portion is rst removed by the blades B operating against the die D, and the outer portions then removed by blades B, operated against the lateral blocks E and F at or nearly at right angles to the direction of motion in making iirst cut by means ot' the wedge Il', or other equivalent device, substantially as specied.
In testimony that I claim the above I have hereunto subscribed mynamein the presence of two witnesses.
JOHN KOEHLER.
