IMPROVEMENTS IN APPARATUS FOR CUTTING "SHEARINGS." OR OTHER METAL STRIPS OR PIECES
Year: 1884

page_text: We CHARLES GOLDWORTH BIGGS and THOMAS WILDE both of Newport in the
County of Monmouth Managers of Tinplate Works, do hereby declare the nature
of said invention for IMPROVEMENTS IN APPARATUS FOR CUTTING "SHEARINGS."
OR OTHER METAL STRIPS OR PIECES to be as follows:-
Upon a shaft are rigidly keyed a series of shear or cutting blades and between
each of such blades and at the end of the apparatus, is a stationary rib carrying
the lower or fixed knives. The main or driving shaft passes through and is
supported by the said ribs, and is driven by means of a crank, cog or other suitable
gearing and, when the apparatus is employed for cutting shearings, preferably from
the same shaft that drives the mill shears. In this case the machine may advan-
tageously be placed below the mill shears, and in such a position that the shearings
will fall therefrom upon the lower or fixed knives at the time when the shear
blades are open to their fullest extent, the said shear blades gradually closing upon
and cutting the shearings into small pieces which fall through between the fixed
ribs into a suitable receptacle beneath, from which they can be removed as
required.

"
OR OTHER METAL STRIPS OR PIECES" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to apparatus particularly adapted for the cutting of
shearings or other metal strips or pieces and to clearly explain how our invention
may be practically employed reference is made to the accompanying drawings
which form part of this specification and in which
Figure 1 represents a sectional elevation and Figure 2 a plan of the apparatus.
Upon a shaft A are rigidly keyed a series of reciprocating shear or cutting
blades B carrying knives or cutters E, and between each of such blades, and at the
end of the apparatus, is a stationary rib C carrying the lower or fixed knives D.
The main or driving shaft A passes through and is supported by the said ribs C
and is driven by means of a crank G, cog or other suitable gearing, and, when the
apparatus is employed for cutting shearings preferably from the same shaft that
drives the mill shears. In this case the machine may advantageously be placed
below the mill shears, and in such a position that the shearings will fall therefrom
upon the lower or fixed knives D at the time when the shear blades B are open to
their fullest extent the crank G being then in the position indicated by dotted
lines at H, the said shear blades gradually closing upon and cutting the shearings
into small pieces which fall through between the fixed ribs C into a suitable
receptacle I beneath, from which they can be removed as required.
Having now particularly described and ascertained the nature of our said
învention and in what manner the same is to be performed we declare that what
we claim is
In apparatus for cutting shearings or other metal strips or pieces the com-
bination of two or more reciprocating cutter blades secured to the same shaft
with an equal number of fixed cutters secured to or forming part of the framework
all arranged and operating substantially as and for the purposes specified.
