PROVISIONAL SPECIFICATION.
Machines for Cutting or Shearing Iron or Steel Bars or Beams of
Channel, Z, or Angle Iron Sections.
We, Hucu SMITH Senior, HUGH SMITH Jur., and OSBOURNE SMITH,
Engineers, Possil Engine Works, Glasgow, in the County of Lanark, do hereby
declare the nature of this invention to be as follows:--
Our invention consists in new and improved machines for cutting or shearing
iron or steel bars or beams of channel, Z, or angle iron sections, and in the shape
and manner in which the blades of the aforesaid machines work.
Figs. 1 and 2. Sheet 1. represent a front and side elevation respectively of a
hydraulic machine for shearing channel and angle iron bars or beams. The
plate A. is made adjustable, being moved out and in by means of the screw B. and
hand wheel C. The plate A is kept back clear until the channel bar or beam D. is
placed in position, when it is moved forward till the edge of this plate rests on the
beam. Pressure water is then admitted to the small cylinder M. by means of the
lever handle H. and valve V. The pressure water then actuates the ram O. and
holds the channel bar or beam fast. Pressure water is then admitted to the
cylinder E. actuating a ram and slide S. which slide, having the blades attached
to the end of it, shears the channel beam. To relieve the channel beam the
handles H and K. are put back; and the plate is relieved by the hand wheel C.
This machine may also be used for shearing angle iron or steel bars.
Figs. 3. 4. and 5. Sheet 1. represent various shapes to which we may make these
blades; and we may make this machine with or without the holding cylinder M.
and ram O. We may also work this machine by gearing or screws or a combination
of these, or we may adapt these styles of blades to any machine.
Fig. 6. Sheet 2. represents a hydraulic machine for shearing Z and angle iron
or steel bars, in which A. represents the adjustable blade which is moved out and
in by means of hand wheel C. to suit the different sizes of bars or beams.
E. represents the cylinder to which pressure water is admitted, actuating a ram
and slide S. To the end of slide S. the shearing blades are fixed, which shear the
beam. The cylinder E. is placed at an angle in order that the web of the Z beam
is horizontal when the beam is being cut. We may fit a holding-down cylinder for
holding the beam, to this machine similar to that described in connection with
Figs. 1 and 2, Sheet 1. We may work this machine by means of gearing or
screws or a combination of these, or we may apply this style of blades to any
machine.
Figs. 7. and 8., Sheet 2. represent the blades of this machine shearing angle iron
or steel bars in two methods.

page_text: be performed, to be particularly described and ascertained in and by the following
statement:-
-
Our invention consists of new and improved machines for shearing iron or steel
bars or beams of channel, Z, and angle iron sections, and in the shape, and manner
in which the blades of the aforesaid machines work.
Figs. 1 and 2, in the drawings left with the Provisional Specification, represent
a front and side elevation, respectively, of a hydraulic machine for shearing channel
bars. The blade A. is made adjustable, being moved out and in by means of the
screw B and hand wheel C. The blade A is kept back clear until the channel or
beam D is placed in position, when it is screwed forward till its edge rests on the
beam. Pressure water is then admitted to the small cylinder M by means of the
lever handle II. and valve V, and this actuates the rain which holds the channel
bar fast. The pressure water is then admitted to the cylinder E by means of the
handle Kand valve V which actuates a ram and slide S, which having the blades
attached to the end, shears the channel beam. To relieve the channel beam the
handles H&K are put back, and the blade A is relieved by hand wheel C.
A similar adjustable blade to A with screw and hand wheel similar to B & C,
may be fitted at opposite side, in place of the fixed blade as shown,
Figs. 3, 4 and 5 in drawings left with the Provisional Specification represent
various shapes to which we may make these blades, and we may make this machine
with or without the holding cylinder M and ram 0. We may also work this
machine by gearing or screws, or a combination of these, or we may adapt these
blades to any machine.
Fig. 6 in drawings left with the Provisional Specification represents a hydraulic
machine for shearing Z and angle iron or steel burs, in which A represents the
adjustable blade which is moved out and in to suit different sizes of bars or beams
by means of hand wheel ('. E represents the cylinder to which pressure is
admitted, actuating a ram and slide S. To the end of slide S the blades are fixed
which shear the beam. The cylinder E is placed at an angle in order that the web
of Z beam may he horizontal when being ent. We may work this machine by
means of gear or screws, or a combination of these, or we may apply this style of
blades to any machine.
Figs. 7 & 8 in drawings left with Provisional Specification represent the blades
of this machine shearing angle bars in two styles.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1st. The combination of parts and arrangements as described herein, and as
shown in the drawings left with the Provisional Specification, including the vice
ram for fixing the bars or beams.
2nd. The arrangement of shear blades as particularly described herein and as
shown in drawings left with the Provisional Specification, as applied to a hydraulic
machine, or as applied to any other machine for the same purpose, whether driven
by steam, by gearing or belts, or any other power.
