Improvements in Machines for Making Sheet Metal Lathing, and
in the Manufacture of such Lathing.
I, GEORGE HAYES of 71 Eighth Avenue in the City and State of New York,
United States of America, Civil and Mechanical Engineer, do hereby declare the
nature of this invention to be as follows:-
:-
My invention relates to the manufacture of certain sheet metal lathings and
consists of certain specially formed dies die rollers and corrugating or ridging
rollers in suitable machine form and combination with certain combinations of parts
and devices of which the machine is composed and rendered effective for its purpose
also of the new or improved lathing a product of this machine also of the new or
improved method by which the said lathing is produced and also of a lubricating
and coating apparatus used in conjunction and combination with this machine all
as hereinafter more fully described-reference being had to the accompanying
drawings in which :-
Fig. 1 represents a vertical section showing a portion of a machine frame with a
set of slitting and puncturing rolls-a set of corrugating rolls and also a coating
and lubricating apparatus, the section is taken lengthwise the machine and a sheet
of metal is sectionally shown as passing through in the direction indicated by an
arrow.
Fig. 2 is a front elevation of about one half of the front or slitting and puncturing
rolls with end of one side of machine frame.
Fig. 3 is a front elevation of about one half of the rear or corrugating rolls with
one side of machine frame in section.
Fig. 4 is an enlarged section of a portion of the corrugating rolls transversely
to their position in the machine a piece of sheet metal is shown therein as being
formed thereby-the position of the two rolls is reversed from that shown in
Fig. 3.
Fig. 5 is a face view of a piece of the sheet metal lathing showing stages of con-
struction the upper part of the figure illustrating its condition after passing through
the slitting and puncturing rolls and the lower part illustrating its condition during
and after passing through the corrugating rolls and finished ready for sale or use.
Fig. 6 is a side view of two of the puncturing dies with portion of the ring
of which they are a part.
Fig. 7 is a front view of one of the dies of Fig. 6.
Figs. 8 and 9 are cross sections showing modifications in forming the lathing
sheet.
On the drawings:-A indicates the parts of the machine frame, B a table or
shelf upon which the blank sheets are laid one by one and fed to the machine.
C is a table or shelf whereon the finished lathing sheets are received from the
machine.
The machine is provided with four rolls; D and E are the two front rolls as a
set and F and G are the two rear rolls also as a set the front rolls D and E are
advantageously formed as a shaft having thereupon a series of rings arranged at
suitable distances apart with between every two rings a separating ring or washer
of lesser diameter all keyed and secured to the shaft to turn therewith and constitute

page_text: the operating face certain of the projecting rings of the upper roll, D are formed as
cutters D' and adapted to cut slits of desired length at intervals as the sheet passes
through and certain others of the projecting rings indicated at D' are formed and
adapted to puncture apertures at intervals in the sheet as it passes through and
turn out the edge-metal of the initial cuts, into a position, in which such may rest
integral with the sheet as tongues hooks or barbs.
The lower roll E has a surface formed into annular ridges systematically and by
means of rings upon a shaft or otherwise.
The ridges to carry.the sheet operated-upon by the cutters and puncturing dies
of roll D and the grooves to receive the thrust as they cut through the sheet metal
and such of them-as necessary are of suitable width and depth to admit free passage
to projecting tongues of edge-metal turned ontwardly from the sheet by the
puncturing dies D2.
A set of stripper rods are shown at H serving to keep the sheet. level and in
direct line between the front and rear rolls as it passes onwards.
The rear rolls F and G also may be constructed as rings and washers upon a
shaft so as to be changeable but. I prefer to form them by lathe in, the solid, metal
surface of pattern as shown in Figs. 3. and.4 in annular ridges and grooves.
In either case space is provided between the ridges at certain points wherein the
web of metal around the slits.can move freely as the slits, expand as at G while
lateral movement of the sheet is prevented by pressure where the rolls bind so that
the sheet remains of the same width after corrugating it as when it was previously
flat and no loss of covering capacity is incurred.
It will be seen by reference to Figs. 3.and 4 that between every two gangs or
groups of corrugations in roll G there is a flat surface grouped corrugations are
shown at Gand the flat between at G the latter being of sufficient width to afford
space for the punctured apertures. Lof Fig. 5-in the lathing sheet with turned out
tongues of edge-metal to pass.through.
The flat spaces may be raised in the lathing-sheet as in Figs. 4 and 5..or flush
with the back of the sheet as in Figs. 8 and 9 and of sufficient width for one row of
tongued apertures as in Figs. 4 and 8.or more rows as in Fig. 9 the rolls being
formed to thus produce them and pass. them. through, when desired. All the rolls
are geared together in the usual manner to rotate in unison,and the usual appliances
for power connected.
The slitting dies of roll D are arranged in gangs according to the desired style
of corrugations. ridges and hollows.while between every two gangs is arranged one
or more rings having die projections shaped as shown in Figs. 6 and 7 these.dies.D'
puncture apertures at intervals and turn outwardly from the plane of the sheet the
edge-metal of the cuts, to stand as tongues hooks, or barbą.
These dies are formed with the puncturing, apex a back of the centre or radial
line shown dotted at b. and with: four..convex faces,c,occextending, backward
therefrom the apex edge.a. is. arranged: transversely to the direction of the turn of
the roll the manner of puncturing and making, the apertures is shown in Fig. 6 the
sheet indicated at J.
This formation of dies described is to facilitate their entering and leaving the
sheet and to enable them to turn out the tongues, of uniform, length and curve.
In front of the machine is shown in connection a coating or coating and
lubricating apparatus consisting of a vat or basin. K spreading rolls and M,
furnishing tube N, supply tube O, extending to any suitable reservoir tank, barrel,
etc., regulating valve P. and outlet Q leading downward. from the rat K through
the bottom. When desired an extra furnishing tube N¹ is added. The tubes N
and N¹ are formed with a line of perforations through which the liquid reaches the
rolls and the surface of the rolls is provided with a suitably absorbent covering.
The vat K catches the dropping liquid returning it to the lower roll.
Back of the spreading or coating. rolls I sometimes use another set operating dry
-arranged as at Rand Swhich serve, to remove any excess of liquid from the sheet
and aid in drying the liquid upon the surface of the sheet metal.

page_text: Lubricating the metal enables the sheet to pass more readily through the machine
and coating it serves to protect the surfaces from oxidation.

The lubricating and coating, apparatus' may be readily removed from the
machine whenever desirable and used at any distance therefrom. The rolls
thereof are all properly geared together and may be geared with the machine
gearing or not as desired.
Shear or knife cutters with continuous cutting edge may be inserted at any
point desired to the front rolls D. E by removing rings and substituting the
shear rings so that a full width sheet will be divided into two narrower ones at
any time desirable.
So far as the slitting of a. sheet of metal at intervals in lines by a machine with
rotating cutters or slitting dies and then corrugating throughout the' sheet expand-
ingly the principle used in this machine is essentially the same as described in my
Patent No. 405 of 1894 but the arrangement of cutters and corrugating ridges in
gangs or groups and corrugating the sheet. on certain lines only with flat spaces
between whether raised or not is new together with the puncturing dies of novel
construction and added lubricating apparatus.
The lathing sheet' also presents novel features not shown in my aforesaid British
Patent.

1 GEORGE HAYES of 71 Eighth Avenue in the City and State of New York,
United States of America, Civil. and Mechanical 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 the manufacture of certain sheet metal lathings and
consists of certain specially formed dies die rollers and corrugating or ridging
rollers in suitable machine form and combination with certain combinations of parts
and devices of which the machine is composed and rendered effective for its purpose
also of the new or improved lathing a product. of this machine also of the new or
improved method by which the said lathing is produced. and. also of a lubricating
and coating apparatus used in conjunction and combination with this machine all
as hereinafter fully described and finally pointed out in the claims.
Referring to the drawings left with the Provisional Specification:-

-
Fig. 1 represents a vertical section showing a portion of a machine.frame with a.
set of slitting and puncturing rolls-a set of corrugating. rolls and also a coating
and lubricating apparatus, the section is taken lengthwise the machine and a sheet.
of metal is sectionally shown as passing through in the. direction indicated by an
arrow.
Fig. 2 is a front elevation of about one half of the front or slitting and puncturing
rolls with end of one side of machine frame.
Fig. 3 is a front elevation of about one half of the rear or corrugating.rolls with
one side of machine frame in section.
Fig. 4 is an enlarged section of a portion of the corrugating rolls transversely to
their position in the machine a piece of sheet metal is shown therein as being formed
thereby the position of the two rolls is reversed.from that shown in Fig. 3.

page_text: Fig. 5 is a face view of a piece of the sheet metal lathing showing stages of
construction the upper part of the figure illustrating its condition after passing
through the slitting and puncturing rolls and the lower part illustrating its condition
during and after passing through the corrugating rolls and finished ready for sale
or use.
Fig. 6 is a side view of two of the puncturing dies with portion of the ring of
which they are a part.
Fig. 7 is a front view of one of the dies of Fig. 6.
Figs. 8 and 9 are cross sections showing modifications in forming the lathing
sheet.
On the drawings:-A indicates the parts of the machine frame, B a table or shelf
upon which the blank sheets are laid one by one and fed to the machine. C is a
table or shelf whereon the finished lathing sheets are received from the machine.
The machine is provided with four rolls; D and E are the two front rolls as a
set and F and G are the two rear rolls also as a set the front rolls D and E are
advantageously formed as a shaft having thereupon à series of rings arranged at
suitable distances apart with between every two rings a separating ring or washer
of lesser diameter all keyed and secured to the shaft to turn therewith and constitute
the operating face certain of the projecting rings of the upper roll D are formed as
cutters D' and adapted to cut slits of desired length at intervals as the sheet passes
through and certain others of the projecting rings indicated at D' are formed and
adapted to puncture apertures at intervals in the sheet as it passes through and turn
out the edge-metal of the initial cuts into a position in which such may rest integral
with the sheet as tongues hooks or barbs.
The lower roll E has a surface formed into annular ridges systematically and by
means of rings upon a shaft or otherwise.
The ridges to carry the sheet operated upon by the cutters and puncturing dies
of roll D and the grooves to receive the thrust as they cut through the sheet metal
and such of them as necessary are of suitable width and depth to admit free passage
to projecting tongues of edge-metal turned outwardly from the sheet by the
puncturing dies D³.
A set of stripper rods are shown at H serving to keep the sheet level and in
direct line between the front and rear rolls as it passes onwards.
The rear rolls F and G also may be constructed as rings and washers upon a
shaft so as to be changeable but I prefer to form them by lathe in the solid inetal
surface of pattern as shown in Figs. 3 and 4 in annular ridges and grooves.
In either case space is provided between the ridges at certain points wherein the
web of metal around the slits can move freely as the slits expand as at G while
lateral movement of the sheet is prevented by pressure where the rolls bind so that
the sheet remains of the same width after corrugating it as when it was previously
flat and no loss of covering capacity is incurred.
It will be seen by reference to Figs. 3 and 4 that between every two gangs or
groups of corrugations in roll G there is a flat surface grouped corrugations are
shown at G2 and the flat between at G³ the latter being of sufficient width to afford
space for the punctured apertures I of Fig. 5 in the lathing sheet with turned out
tongues of edge-metal to pass through.
The flat spaces may be raised in the lathing sheet as in Figs. 4 and 5 or flush
with the back of the sheet as in Figs. 8 and 9 and of sufficient width for one row of
tongued apertures as in Figs. 4 and 8 or more rows as in Fig. 9 the rolls being
formed to thus produce them and pass them through when desired. All the rolls
are geared together in the usual manner to rotate in unison and the usual appliances
for power connected.
The slitting dies of roll D are arranged in gangs according to the desired style
of corrugations ridges and hollows while between every two gangs is arranged one
or more rings having die projections shaped as shown in Figs. 6 and 7 these dies D
puncture apertures at intervals and turn outwardly from the plane of the sheet the
edge-metal of the cuts to stand as tongues hooks or barbs.

page_text: C
These dies are formed with the puncturing apex a back of the centre or radial
line shown dotted at and with four convex faces c c c extending backward
therefrom the apex edge a is arranged transversely to the direction of the turn of
the roll the manner of puncturing and making the apertures is shown in Fig. 6 the
sheet indicated at .J.
This formation of dies described is to facilitate their entering and leaving the
sheet and to enable them to turn out the tongues of uniform length and curve.
In front of the machine is shown in connection a coating or coating and lubricating
apparatus consisting of a vat or basin K spreading rolls L and M, furnishing tube N,
supply tube O, extending to any suitable reservoir tank, barrel, etc., regulating
valve P and outlet Q leading downward from the vat K through the bottom.
When desired an extra furnishing tube N is added. The tubes N and N' are
formed with a line of perforations through which the liquid reaches the rolls and
the surface of the rolls is provided with a suitably absorbent covering. The vat K
catches the dropping liquid returning it to the lower roll.
Back of the spreading or coating rolls I sometimes use another set operating dry
arranged as at R and S which serve to remove any excess of liquid from the sheet
and aid in drying the liquid upon the surface of the sheet metal.
Lubricating the metal enables the sheet to pass more readily through the machine.
and coating it serves to protect the surfaces from oxidation.
The lubricating and coating apparatus may be readily removed from the machine
whenever desirable and used at any distance therefrom.
The rolls thereof are all
properly geared together and may be geared with the machine gearing or not as
desired. Any suitable coating material may be used for instance a petroleum
product.
Shear or knife cutters with continuous,cutting edge may be inserted at any point
desired to the front rolls DE by removing rings and substituting the shear rings so.
that a full width sheet will be divided into two narrower ones at any time desirable.
So far as the slitting of a sheet of metal at intervals in lines by a machine with
rotating cutters or slitting dies and then corrugating throughout the sheet expand-
ingly the principle used in this machine is essentially the same as described in my
Patent No. 405 of 1894 but the arrangement of cutters and corrugating ridges in
gangs or groups and corrugating the sheet on certain lines only with flat spaces
between whether raised or not is new together with the puncturing dies of novel
construction and added lubricating apparatus.
The lathing sheet also presents novel features not shown in my aforesaid British
Patent.
Having now particularly described and ascertained the nature of my said inven-.
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1. In a machine for manufacture of sheet metal lathing a rotating series of dies
formed and adapted to form interval apertures through the sheet puncturing
enlarging and turning out the edge-metal of the openings thus formed in the form
of tongues integral with the sheet as set forth.
