Improvements in Machines for Perforating and Grooving Sheet-
metal, Chiefly Designed for Use in the Manufacture of Metallic
Lathing.
I, GEORGE HAYES of No. 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 a machine specially constructed and adapted for the manu-
facture of a certain metallic lathing also of my own invention, and consists of the
special devices and.combinations of parts as hereinafter fully described reference being
had to the accompanying drawings in which
Figure 1. represents a front elevation of the machine complete-being the feed face.
Figure 2. is a side elevation of the machine with fly wheel removed.
(
Figure 3. is a face view of a piece of sheet-metal showing the form of cut made by
the dies of the machine while entering.
Figure 4. is a back view of a piece of sheet metal after the dies have passed through
it and finished.
Figure 5. is a face view of a piece of sheet-metal after the operation of puncturing
is completed-In this condition it is ready for use as lathing to receive plaster-applied
to this face.
Figure 6. is a sectional view of the parts which form the apertures and tongues-
to wit dies with a portion of the carriage to which they are attached-a tripper to
prevent the sheet following, the dies as they rise and a grooved bed upon which the
metal lies stationary during the operation. A piece of sheet-metal is shown therein-
the dies being down, having punctured the aperture and curled back the tongues.
Figure 7. is a sectional view of the parts shown in Fig. 6. on a plane at right
angles thereto.
J
An edging die is also shown which forms a corrugation at the edge of the
metal.
Figure 8. is a rear elevation or view of the delivery face-with rolls which
draw out the sheet and finish edge corrugation removed to show the puncturing
dies, carriage and bed.
Figure 9. is a vertical section of the machine, from front to rear, showing a sheet
of metal entering.
Figure 10. is a horizontal section of the machine just above the bed-also showing
a sheet of metal entering. This view shows the lowermost roller used to draw out
and finish the sheet, grooved throughout its length correspondingly with the grooved
bed.
Figure 11. is a face view or elevation of the rear rolls differing slightly from those
of Fig. 10. in this case shown as grooved centrally (or reduced) to one long groove.
At the two ends are shown roll-dies as a part thereto whereby edge corrugations are
smoothed out and finished.
The parts in Figs. 3, 4, 5, 6 and 7, are drawn full size-
On the drawings A, indicates the several parts of the machine constituting its
framework, and which may be of any suitable pattern.
B, indicates the driving shaft supplied with Belt pulleys at B¹, also flywheel at B³,
either of which may be dispensed with.
C, indicates the crankshaft in gear with the driving shaft by toothed wheels as at D.
E, indicates Pitmen (of which there are two) connecting crankshaft with a recipro-
cating carriage F.
...

page_text: The ritmen may be in one length or in two with threaded sleeve as at for
regulating their length.
F, indicates the carriage to which the dies are connected, directly or indirectly, by
any suitable means.
G, indicates the bed upon which the sheet of metal rests under the dies--when
receiving: the stroke of the dies.
In Fig. 3. is shown the cut made by the die as it enters-at a, first-and those
marked b, cut by the edges as it descends.
Fig. 4, shows the back of the sheet, which is uppermost in the machine.
: Fig. 5, shows the face of the sheet to receive plastering-with punctured apertures
and the edge-metal turned outward and backward forming tongues and lips.
H, indicates the dies (full size) in Figs. 6 and 7, flatwise in Fig. 6, and edgewise
in Fig. 7.
Each die has its angles formed to cut the metal as it enters, and all its faces convex
as at c, and d, to turn out the edgemetal.
The apex
a-is a cutting edge also.
The bed G, is grooved to receive the downward thrust of the dies also to accomodate
the downward, bending of the tongues, also to allow their passage outwards, as
indicated at I.
At J, is shown a tripper bar, slotted to allow the dies to pass downwards--the
tripper lies over the sheet and prevents its rising or sticking to the dies.
K, indicates the sheet of metal and K', the apertures therein.
The dies are set in two rows, alternating, to "break joint" but however they may
be placed otherwise.
The apertures with their tongues are formed complete at one stroke downward.
To facilitate joining the sheets together to a wall or other support I form a
corrugation at the edge as at L, dies are provided for forming the same as at M,
with rounded face, the bed being grooved beneath to suit, as a matrix.
It is nescessary that the sheet should rest to receive the downward stroke and
move the proper distance as the dies rise, for the next stroke. This movement is
brought about by two feed rolls at N, geared together at N', which move the sheet
forward to and through the dies and two rolls at O, geared together as at O',
which serve to draw out the sheet after it has left the feed rolls N¹.
The lowermost of the front and rear rolls are connected by gear wheels P, and Q,
and intermediate wheel R.
To the wheel R, is applied a ratchet wheel S, with swinging pawl T, connected
to the crank shaft C, by adjustable Rod U, whereby motion is communicated to the
Rolls N, and O.
I do not confine myself to the exact arrangement of Pawl and connecting Rod
as any other analogous means may be substituted.
A hold-back spring at V, is used to prevent backward action of Ratchet wheel.
The Rolls O, may be formed in two ways, as in Fig. 10, where the lowermost
Roll is grooved throughout to correspond with the grooved bed G, or as shown in
Fig. 11 with middle portion reduced in size as one wide groove.
In either case the end groove to lower roll is formed as a Matrix and the upper
roll with a male to fit thereto-whereby a finish is given to corrugations formed by
by dies M, of carriage F.
It is essential that the dies have curved faces terminating in a cutting point, or
apex, to enable them to enter and properly turn the edge-metal, also that all angles
which enter the sheet-metal be sharp to cut gradually while entering without tearing
away any portion to weaken the tongues.
It is essential that the Bed beneath shall be grooved to receive the downward
thrust of the lies to admit the projecting edge-metal (tongues and lips) and permit
of their free passage outwardly on a horizontal plane-also that sufficiency of the
metal surface of the Bed is left to support the sheet-metal—with shoulders to prevent
further tear than desired.

page_text: It is essential that rollers be provided to grip the sheet after it has left the feed-
rolls and draw it outwardly on a horizontal plan-and that the lowermost roller be
grooved or diminished in diameter centrally to permit of free passage for the projecting
tongues through without flattening them.
It is essential that the feed and draw rollers operate in unison-and that they be
moved only when the dies are out of the sheet and remain quiescent during the
puncturing, that the sheet-metal may be at rest to receive the thrust.
It is essential for corrugating the edge of the sheet that a pressing die form the
corrugation by downward stroke corresponding with the thrust of the main dies
while the sheet is at rest and held firm against lateral movement by the cutting dies-
And that the sheet be passed between roller dies to finish and smooth out the grooves
-for if the grooves were left to roller dies for forming, the groove might become
uneven (or awry) under slight difference of tension-in such case side guides would
be necessary outward to the rolls which would tend to friction and disarrange the
proper feeding and exact timing requisite to bring the punctured apertures at regular
and exact distances apart.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
First. A machine for puncturing sheet metal, wherein the dies are so constructed
that, in puncturing the metal they will turn or curl the same outward to form tongues
substantially as hereinbefore described.
Second. In a machine for manufacture of metallic lathing, dies having each cutting
apex, cutting edges and convex faces, adapted to open and turn outwardly and back-
wardly with a curve the sheet metal as and for the purposes herein set forth.
Third. In a machine for forming tongued apertures in sheet metal, the cutting
dies Heach having its puncturing end formed with the cutting edges and convex faces
connected to a reciprocating carriage provided with moving mechanism and arranged
over a grooved bed in such manner that the stroke of each die is received in a groove
with the tongues of metal forced downwards by the puncturing movement while the
shoulders or raised portions of the bed between the grooves sustain the sheet, essentially
as shown and described.
Fourth. As a device for puncturing sheet-metal and turning outwardly and back-
wardly the edge-metal into curved tongues-the cutting die herein set forth having
cutting edge a, and the convex faces c, and d, essentially as shown and described.
Fifth. The combination of the grooving die M with a reciprocating carriage F,.
to form a groove by stamping or pressure over a matrix essentially as shown and
described.
Sixth. In combination with the dies M, and their matrices-the rollers O, the upper
having a bead and lower having concavity whereby the grooving of sheet-metal is
effected essentially as shown and described.
Seventh. The grooving of lower roller O, in line with grooves of bed G, for passage.
of the raised tonges and lips to the sheet of sheet-metal essentially as shown and
described.
