Improvements in or connected with Reversible Metallic Lathing and
Machinery for Producing the same.
HERBERT YOUNG DICKINSON 56 Gray's Inn Road London W.C. Engineer
do hereby declare the nature of this invention to be as follows:-
My invention relates to dies and corresponding matrices for producing metallic
lathing. I generally construct my machine with a pair of parallel stamping
rollers being geared together with similar wheels at one or both ends of the roller
shafts so that they run together truly. Upon these rollers are dies and matrices
of a form described below. These rollers are usually geared to another shaft
carrying a fly-wheel at one end and fast and loose pulleys at the other end upon
which shaft power is applied to the machine. In some cases I fix parallel feed or
guide rollers to the machine in which case the sheet metal passes between these
rollers as well as between the stamping rollers of the machine.
Fig. 1 is a top view of one of the cutting dies upon one of the rollers of the
machine, A being the die and B a inatrix, there being a similar die and matrix,
on the other stamping roller of the machine but reversed in position so that each
die has its corresponding matrix into which to gear, the two rollers of the machine
being studded over their surfaces at suitable distances with these dies and
matrices and the two rollers registering correctly in respect of their dies and
matrices.
Fig. 2 is a section of part of one of the stamping rollers through line Y Z of
Fig. 1 and at right angles thereto A being the die aud B a matrix.
Fig. 3 is an end view of part of one of the stamping rollers A. A being dies the
dotted lines showing the position of matrices.
Fig. 4 is a face view of sheet metal showing form of cut made by dies of the
machine while entering.
Fig. 5 shows view of a piece of sheet metal back or front after dies have finished
their work.
I form slight corrugations at intervals across the sheets between the stamped
puncturings to strengthen the sheets such corrugations being made by suitable
raised and corresponding recessed parts which are around the rollers of the
machine. I have shown generally the form of dies aud matrices used upon my
stamping rollers for producing metal lathing and it will be obvious that the shape
of the cup formed by dies may be modified, or two dissimilar cups may be produced
or one cup alone, the invention being the arranging of the dies and matrices upon
the stamping rollers so as to form a cutting edge upon the line w. z. in Fig. 1 and
at the same operation stamping and drawing or bulging the sheet metal into the
required half cup form. In some cases these dies may be fixed on a reciprocating
carriage so as to stamp the sheet metal. In some cases I prepare slabs of these
punctured and stamped sheets of suitable sizes with connecting pieces to be readily
fixed together for temporary buildings being metal lathing sheets covered with
plaster, plaster may be run in the joining crevases which plaster joint is easily
destroyed by bending one slab from another when it is desired to take the building
down. These sheets of stamped metal can be formed into cylinders, of any desired
diameter and they can be coated with cement or other plaster on both sides, if
required and thus form pipes for conduits. Slabs of this lathing of desired sizes
and shapes may be coated with cement on both sides which cement is ornamented
with headings scrolls and other representations of chiselled stone and these coated
slabs may then be used as ordinary stone for building purposes and especially

page_text: where facing is required bearing ornamental designs. I do not restrict myself to
making the cuttings and bulgings in a certain position upon the sheets of metal,
but they may be varied as thought fit, being first in one direction and then in
another the dies and matrices being accordingly around the rollers of the machine.

HERBERT YOUNG DICKINSON late of 56 Gray's Inn Road London W.C.
11 Queen Victoria Street, E.C. 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 relates to dies and corresponding matrices for producing metallic
lathing. generally construct my machine with a pair of parallel stamping rollers
the two rollers being geared together with similar wheels at one or both ends of
the roller shafts so that they run truly together. Upon these rollers are dies and
matrices of a form described below. These rollers are usually geared to another
shaft carrying a fly-wheel at one end and fast and loose pulleys at the other end
upon which shaft power is applied to the machine. In some cases I fix parallel
feed or guide rollers to the machine, in which case the sheet metal passes between
these rollers as well as between the stamping rollers of the machine.
Fig. 1 is a top view of one of the cutting dies upon one of the rollers of the
machine, A being the die and B a matrix, there being a similar die and matrix on
the other stamping roller of the machine but reversed in position so that each die
has its corresponding matrix into which to gear the two rollers of the machine
being studded over their surfaces at suitable distances with these dies and
matrices and the two rollers registering correctly in respect of their dies and
matrices.
Fig. 2 is a section of part of one of the stamping rollers through line Y. Z. of
Fig. 1 and at right angles thereto A being the die and B a matrix.
Fig. 3 is an end view of part of one of the stamping rollers A. A being dies, the
dotted lines showing the position of matrices.
Fig. 4 is a face view of sheet metal showing form of cut made by dies of the
machine while entering.
Fig. 5 shows view of a piece of sheet metal back or front after dies have finished
their work.
I form slight corrugations at intervals across the sheets between the stamped
puncturings to strengthen the sheets such corrugations being made by suitable
raised and corresponding recessed parts which are around the rollers of the
machine. have shown generally the form of dies and matrices used upon my
stamping rollers for producing metal lathing and it will be obvious that the shape
of the cup formed by dies may be modified, or two dissimilar cups may be produced
or one cup alone, the invention being the arranging of the dies and matrices upon
the stamping rollers so as to form a cutting edge upon the line W. X. in Fig. 1
and at the same operation stamping and drawing or bulging the sheet metal into
the required half cup form. In some cases these dies may be fixed on a recipro-
cating carriage so as to stamp the sheet metal. In some cases prepare slabs of
these punctured and stamped sheets of suitable sizes with connecting pieces to be
readily fixed together for temporary buildings being metal lathing sheets covered
with plaster, plaster may be run in the joining crevases, which plaster joint is
easily destroyed by bending one slab from another when it is desired to take the
building down. These sheets of stamped metal can be formed into cylinders of

page_text: any desired diameter and they can then be coated with cement or other plaster on
both sides if required and thus form pipes for conduits. Slabs of this lathing of
desired sizes and shapes may be coated with cement on both sides which cement is
ornamented with headings scrolls and other representations of chiselled stone and
these coated slabs may then be used as ordinary stone for building purposes and
especially where facing is required bearing ornamental designs. I do not restrict
myself to making the cuttings and bulgings in a certain position upon the sheets of
metal, but they may be varied as thought fit, being first in one direction and then
in another the dies and matrices being accordingly around the rollers of the
machine. All drawings above referred to have been left with Provisional
Application.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
Firstly. The operation of cutting, stamping or bulging the sheet metal as above
described.
Secondly. The construction of the machine as above described.
Thirdly. The preparation of building slabs as above described.
Dated this Fourth day of October 1894.
