Improvements in Coping or Shearing Machines.
I, EBENEZER ARTHUR WILLIAM JEFFERIES, a citizen of the United States, residing at
No. 400, Chestnut Street, in the City of Philadelphia, in the County of Philadelphia,
and State of Pennsylvania, Consulting Engineer, do hereby declare the nature of
this invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
My invention has relation to a machine for coping metal beams, that is, a machine
preferably operated by hydraulic pressure, wherein the flanges of metal beams may
be sheared or coped by one operation in contradistinction to a series of operations as
hitherto, and in order to permit the web of the beam thus unflanged to fit in
between the flanges and abut against the web of a similar beam located at right
angles to the coped beam.
My invention stated in general terms, consists of a machine for coping metal
beams constructed and arranged in substantially the manner hereinafter described
and claimed.
The nature and scope of my invention will be more fully understood from the
following description taken in connection with the accompanying drawings forming
part hereof, in which
Figure 1, is a front elevational view of a bydraulic coping or shearing machine
embodying main features of my invention.
Fig. 2, is a side elevational view, partly sectioned, of said machine.
Fig. 3, is an enlarged front elevational view illustrating in detail, the tool or die,
the anvil or block, the side blocks, the upper vertical movable block, and the metal
beam, all in position so that the beam may be coped or sheared.
Fig. 4, is a top or plan view of Fig. 3, certain parts being removed and broken
away, to show the construction and arrangement of the anvil and side blocks.
Fig. 5, is a perspective view enlarged of the lower end of the coping tool or die.
Fig. 6, is an underneath plan view of the tool or die, illustrating the cutting face
of said tool or die; and
Fig. 7, is a perspective view of an I-beam after the same has been coped, and
illustrating in dotted lines another 1-beam arranged at right angles to the coped
beam and in position to be connected to the coped I-beam.
In the drawings it will be seen that the present invention has been embodied in a
bydraulic shearing press of ordinary type, but it will be readily understood that my
invention may also be applied to any shearing press whether operated hydraulically
or otherwise, without departing from the spirit of the invention since any
modifications necessary in the construction of other machines will readily suggest
themselves to the skilled mechanic.
Referring now to the drawings a, represents the bed of the machine on which is
supported in any suitable manner a bottom block or anvil b, having an opening b¹,
At either side
the edges b, of which are sharp and of a hard material, such as steel.
of the anvil b, is arranged a horizontally movable block d, adapted to be shifted
inward toward the centre of the anvil and outward from the centre by means of
wedges d', or other suitable mechanism, which is preferably controlled by hydraulic
pistons or rams d², as illustrated in Fig. 2, of the drawings. Each block d, has an
opening d³, in that side nearest the anvil b, and this opening d³, has sharp edges d',

page_text: of preferably hard steel to form a cutting or knife-like face for a purpose to be here-
inafter more fully explained. Above the anvil b, is arranged a tool or die e, adapted
to slide vertically towards or away from the anvil b, and operated by a ram or
piston e. This tool or die e, consists of a blade e, having at either end a flange e³,
arranged preferably at right angles to the blade, which flange is tapered or beveled as
at e', on its outer face. The blade e, has also a recessed cutting face e5, of a width
corresponding to the width of the web which is to remain upon the beam to be cut.
Sliding vertically within the flanges es, is a clamping block f, operated by a ram or
piston f, and adapted to approach or recede from the anvil b.
In operation, a beam g, is introduced into the machine with its web g¹, lying flat
upon the anvil b, and its flange g², pressed towards the sides of the anvil b, by the side
blocks d. In this position the clamping block f, is moved downwards against the
upper face of the web gl, to clamp the web tightly down upon the anvil, as illustrated
in Figs. and 3. In this position the tool or die e, is moved downwards, the
flanges e, in connection with the edges d', of the side blocks, cutting off the flanges g²,
of the I-beam, and the blade e, in connection with the edges b², of the anvil cutting
off the web gl, until the I-beam is coped by one and the same operation, as illustrated
in Fig. 7. In the cutting off of the flanges g², of the beam, the tapered flanges et, of
the tool, as the tool descends, crowds the flanges, against the sharp edges of the
knives on the side blocks d, and shears them off by a transverse action rather than by
a vertical action, such as the blade e, makes in cutting off the web g¹, of the
beam, and this it is to be understood is by one and the same operation of the
machine.
It will be manifestly obvious that the tool e, may he employed for shearing
channeled beams as well as I-beams and still be within the scope of my invention.
Having now particularly described and ascertained the nature and objects of
my invention and in what manner the same is to be performed, I declare that
what I claim is:-
1. In a machine for coping or shearing metal beams, a bed supporting an anvil
having an opening provided with sharp edges, a block provided with an opening
having sharp edges, said block adapted to be shifted inward towards the centre of
said anvil and outward therefrom, a tool or die, consisting of a blade having flanges,
and a recessed cutting face in width corresponding to the web to remain upon the
beam to be cut, and a clamping block.adapted to approach and recede from said
anvil, the construction being such that said blade is adapted to shear the web of the
bearn by passing vertically through the same and the flanges to sever the flange of
the beam by a transverse action at one and the saine operation, substantially as and
for the purposes described.
2. In a machine for coping or shearing metal beams, a bed supporting an anvil
having an opening provided with sharp edges, a horizontal block provided with an
opening having sharp edges, said block adapted to be shifted inward towards the
centre of said anvil and outward therefrom by means controlled by a piston or ram,
a tool or die adapted to slide vertically towards or away from said anvil and consisting
of a blade having tapering or beveled flanges at right angles thereto and a cutting
face of a width corresponding to the width of the web to remain upon the beam to be
cut, and a clamping block adapted to slide vertically within said flanges and to
approach or recede from said anvil, substantially as and for the purposes
described.
