Improvements in Machines for Rolling Wired Glass.
I, CHARLES CORNELIUS HARTUNG, a Citizen of the United States, residing at
4100 North Main Street, St. Louis, State of Missouri, United States of America,
Superintendent of the Mississippi Glass Company, do hereby declare the nature
of this invention, and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement, and illustrated
in the accompanying drawings, wherein :-
Figure 1 is a side elevational view of my improved machine;
Figure 2 is a top plan view of the same, being shortened somewhat by breaking
away the middle thereof;
Figure 3 is a front elevational view of the knife-bar and a few of the imbedding-
knives;
Figure 4 is a detailed sectional view through the knife-bar which carries the
imbedding-knives;
Figure 5 is a front elevational view showing a few of the imbedding-knives
and the wire mesh in a position to be imbedded by said knives;
Figure 6 is a top plan view of the lever for operating the imbedding-knives:
Figure 7 is a top plan view of the knife-bar and three of the imbedding-knives;
Figure 8 is a plan view of a piece of glass in which wire mesh has been
imbedded; and
Figure 9 is a sectional view through said piece of glass.
This invention relates to a new and useful improvement in machines for rolling
wired glass, and consists in the means for initially imbedding one end of a wire
mesh in the molten glass to fix the same in position properly for its imbedment
by the roller or rollers; the means for accomplishing this is illustrated in the
drawings as comprising a series of knives. These knives are dipped into the
molten glass, carrying one end of wire mesh and fixing the same into the glass,
after which the knives are withdrawn, the imbedment of the wire mesh being
continued by the imbedding roller or rollers.
In the drawings, I have shown a well-known form of machine to which my
invention is applied, but it is obvious that there may be other machines for
imbedding wire mesh into glass, to which my invention could be applied, and be
capable of accomplishing the results obtained here.
A indicates a casting table, B the rack along the sides thereof; C the fillet for
determining the thickness of the glass; D the frame of a carriage in which the
imbedding-rollers are mounted; E the advance corrugated imbedding-roller;
and F the following smooth finishing roller. The carriage shown in the drawings
is propelled by an electric motor G, having a pinion H on its armature shaft
meshing with a gear I on a counter-shaft, said counter-shaft carrying a pinion J
meshing with a gear K conjoined to the advance corrugated roller E. L indicates
a chute or way in which a panel of wire mesh is placed preparative to being
imbedded into the molten glass.

page_text: So far as the above parts are concerned, they illustrate a well-known form of
machine, and I do not claim the same as my invention.
M indicates two rocking levers pivotally mounted on opposite sides of the
imbedding-roller E, and on the axle thereof.
N indicates a knife-bar formed as part of, or secured to, the front ends of said
rocking-levers M. This knife-bar is more clearly shown in Figures 3 and 4, where
it will be seen to be provided with a series of spacing blocks n between which
the knives are placed, said knives being held in position by through-bolts P,
which, also, pass through the spacing blocks. These knives preferably curve
outwardly at their upper ends, the inner faces of their lower ends being concentric
with the periphery of the imbedding-roller E. The rear ends of the rocking-
levers M are preferably connected, and carry a weight m acting as a counter
balance for the knife-bar, and knives.
Q indicates a link secured to the rear end of one of the levers M and to a bell-
crank lever R pivotally mounted on the carriage-frame 1).
S indicates a link connecting the other end of said bell-crank lever R to a
bell-crank operating lever T pivotally mounted on the framing D. One of the
members of this bell-crank lever T is formed as an operating handle, and is
preferably provided with a latch dog t for holding the knives in their raised
position.
The operation of the machine is obvious. Assuming a panel of wire mesh to
be placed in the chute L, the same passes down until it is supported by the
knives O, which, affording a curved path to the panel of wire mesh, will prevent
said wire mesh from following the imbedding roller. When it is desired to
introduce one end of the panel of wire mesh into the molten glass, the handle T
is depressed, which depresses the knives O, said knives carrying the lower end of
the panel of wire mesh down through the molten mass of glass, in advance of the
imbedding-roller, and under the imbedding-roller, which now takes hold of the
same and imbeds said wire mesh in the plate of glass being formed. The knives
are immediately withdrawn from the mass of molten glass, the panel of wire mesh
feeding itself afterwards without the further manipulation of the knives. The
handle T and the knives are held in their raised position by the engagement of
the latch with the projection on the frame D, as shown in Figures 5 and 6.
When the panel is introduced between the knives and imbedding roller, as shown
in Figures 4 and 5, the curvature which it is forced to assume, creates sufficient
friction to sustain the weight of the panel. When the machine is started, the
friction of the corrugations of the imbedding roller E tends to draw the panel of
wire downward, but it is not sufficient for this purpose. However, when the
knife-blades are depressed, their friction on the panel, together with the friction
of the rotating imbedding-roller, is sufficient to carry the panel of wire mesh
down and under the roller E to imbed one end of said mesh into the molten glass,
after which the knives may be withdrawn as above described, because the glass,
filling the spaces between the strands of wire composing the mesh, holds said wire
mesh in place.
I am aware that many minor changes in the construction, arrangement, and
combination of the several parts of my machine, can be made and substituted
for those herein shown and described, without, in the least, departing from the
nature and principle of my invention.
Having now particularly described and ascertained the nature of my invention,
and in what manner the same is to be performed, I declare that what I claim
is:-
1. In a machine for rolling plate glass, the combination with the imbedding-
roller, of a support for the panel of wire mesh, and means for operating said
support to forcibly introduce one end of the panel of wire mesh into the sheet of
molten glass, said means, also, operating to withdraw said support after the end
of the panel is introduced into the molten glass, substantially as described.

page_text: 2. In a machine for imbedding wire mesh in plate glass, the combination with
the imbedding-roller, of a support for the panel of wire mesh, said support being
located close to the periphery of said imbedding-roller, and means for dipping
said support to force one end of the panel of wire mesh through the mass of molten
glass in front of the imbedding-roller and partially under said imbedding-roller,
said means, also, operating to withdraw said support from the mass of molten
glass after the end of the panel of wire mesh is introduced into the molten glass,
substantially as described.
3. In a machine for imbedding wire mesh into glass, the combination with the
imbedding-roller, of a series of knife-blades arranged in juxtaposition to the
periphery of said imbedding-roller, and means for operating said knife-blades to
introduce a panel of wire mesh into the molien glass, which, panel of wire mesh
is supported by said knife-blades, substantially as described.
4. In a machine for imbedding wire mesh in plate glass, the combination with
the imbedding-roller, of rocking-levers, a knife-bar and knives carried by said
rocking-levers, and means for rocking said levers, substantially as described.
5. In a machine for imbedding wire mesh in plate glass, the combination with
the imbedding-roller, of a rocking knife-bar, a lever for rocking. said knife-bar,
and means for locking said lever in one of its positions, substantially as described.
6. In a machine for imbedding wire mesh in plate glass, the combination with
the imbedding-roller, of rocking-levers mounted on each side of said imbedding-
roller and on the axis of said imbedding-roller, a knife-bar and knives carried
on the front ends of said rocking-levers, a handle, means for locking said handle
in one of its positions, and connected mechanism between said handle and one
end of the rocking-levers, substantially as described.
