Improvements in Machinery for the Manufacture of Plate and
Sheet Glass.
I, NILES MANCHESTER MILLER, of 4101 Chestnut Street Philadelphia in the
County of Philadelphia and State of Pennsylvania United States of America,
Doctor of Medicine, do hereby declare the nature of my invention, and in what
nanner the same is to be performed to be particularly described and ascertained in
and by the following statement:―
My invention relates to improvements in machinery for the manufacture of plate
and sheet glass, the object of the invention being to so construct a machine for the
purpose stated that the plates of glass produced thereby will possess great density,
clearness and smoothness.
A further object of the invention is to so construct a face plate that it can be
employed either for producing a plain or a figured surface on the glass.
A further object is to produce a simple and efficient removable and reversible
face plate for a glass machine.
With these objects in view the invention consists in certain novel features of
construction and combinations and arrangements of parts as hereinafter set forth
and pointed out in the claims.
In the accompanyings drawings:
Figure 1 is a side view of the machine partly broken away.
Figure 2 is a plan view illustrating the means for applying power to the
apparatus.
Figure 3 is an end view.
Figure 4 is a side view of a portion of the apparatus, showing the lower table
and adjacent parts.

Figure 6 is a view of the reversible face plate..
Figure 7 is a plan view of the lower table and a portion of the framework.
Figure 8 is a view illustrating tho mechanism for ejecting a plate of glass from
the machine into the annealing furnace.
Figure 9 is a view of the ejecting mechanism.
Figure 10 is a detail view of the devices for feeding the molten glass to the lower
table.
A represents a main frame, in which shafts or axles a are mounted, said shafts
or axles carrying wheels a' adapted to run on tracks a³, which latter are located in
front of the annealing furnaces, (not shown).
The sides of the main frame A are made with L-shaped grooves or ways a³ for
the accommodation of similarly shaped flanges or guides a projecting from a
movable or sliding frame or carriage B.
Located on the frame A is a series of hydraulic cylinders a³, on the plungers a
of which, a lower table C is located. The table C is preferably made in sections,
the framework comprising frames a having dovetailed grooves or recesses a for
the reception of dove-tailed projections a on bars a disposed on said frames a².
The bars a are provided with dovetailed tenons a adapted to enter dovetailed
grooves al in bars or strips b located at the four sides of the table.

page_text: My improved face plate X is located on the bars a' within the frame composed
of the bars or strips b and secured to said bars or strips by means of bolts a¹³.
From this construction and arrangement of parts it will be seen that the table C
is expansible in both directions.
The face plate X is composed of a series of sections, and each section is composed
of two plates, spaced apart and connected together by means of a number of
posts. In the space between the two plates a, a, heat retaining material will be
placed. By thus constructing the sections of the face plate, they will be much
lighter than if a single solid plate were used, and the expansion and contraction
will be less. One surface of each section of the face plate will be smooth and the
other surface may be figured, or both surfaces may be figured or smooth. When
the several sections of the face plate are placed together with the smooth surfaces
up, the face plate will be adapted for producing a smooth surface on the glass, but
when it is desired to produce a figured surface on the glass, the face plate will be
reversed so that its figured surface will be uppermost, the several sections, when
placed together producing the desired design. The figured surface of the face
plate may be produced in any suitable manner. The figures on the surface of the
face plate may he raised so as to produce a depressed design or figure in the glass,
or a depressed figure may be made in the face plate so as to produce a raised figure
on the glass.
The posts at the edge of the face plate are made with dove-tailed recesses.³
for the reception of double dove-tailed keys 1 whereby to unite said sections to
produce a complete face plate. The sections of the face plate are further secured
together by means of bolts z³.
Located at the longitudinal edges of the frame A are brackets C¹ L-shaped in
cross section, their dopending portions & being disposed between the sides of the
movable table C and the frame A and the horizontal portions of said brackets
being located on top of the side bars of the frame A. The upright portions of the
frame A and the depending portions of the brackets C' are made with aligned
sockets for the reception of pius and on said pins and between the frame A and
brackets C, springs are located, whereby to maintain said brackets snugly
against the table and still permit the expansion of said table. The brackets C' are
fastened to the frame A and held in proper position by means of bolts b*.
The upper faces of the brackets C₁ are, as shown in Figures 4 and 5, normally
disposed somewhat above the face of the table C, the thickness of the proposed
plate of glass being determined by the distance between the upper faces of the
table C and the brackets C. At the ends of the table C are brackets C, identical
with those above described, said brackets C' being disposed between the brackets C³,
as shown in Figure 7.
Mounted in sliding bearings e carried by the movable frame or carriage B in
proximity to one end thereof, is a roller D. The roller D is retained in proper
position relatively to the table C and moved to or from said table for adjustment
by means of a crank s, on which a pinion is secured, said pinion meshing with a
pinion on one end of a screw e', the upper end of which is adapted to enter the
journal box of the roller D. There may be two sets of these devices, one for cach
journal box on the roller D. An arm or bracket d projects from the forward end
of the frame or carriage B, and through it screw threaded crank shafts d¹ pass,
whereby to adjust a hopper carried by said shafts, relatively to the table C.
The outlet of the hopper is provided with a hinged hood or gate d adapted to
normally close said opening. A shaft is mounted in suitable bearings on the
hopper a and carries a hand wheel d. A chain dis secured at one end to the
hood or gate d³ and at its other end is adapted to be wound on the shaft d'. Thus
it will be seen that by operating the hand wheel the hood or gate can be
operated to open or close the outlet of the hopper. In order to retain the hood or
gated in the position in which it shall be set, a ratchet wheel d' is secured to the
sbaft d' and is adapted to be engaged by a pivoted weighted dog. pivoted to the
hopper. The purpose of the hopper d² is to contain molten glass and discharge

page_text: the same on the table C immediately in front of the roller D, when the frame or
carriage B is moved in the manner hereinafter explained;-the thickness of the
plate to be produced being gauged by the relative position of the free edge of the
hood to the outlet of the hopper. In order to compel the molten glass to flow
from the hopper d' regularly and thus be spread on the table in uniform thickness,
the devices now to be explained will be employed. A plunger d is located within
the hopper and adapted to have a vertical movement therein. To this plunger,
screws are attached and on said screws, pinions are located and adapted to
receive motion from pinions. carried by a shaft d³. At one end the shaft n
carries a gear which receives motion from a gear on a shaft de, carrying
another gear d (Fig. 1) meshing with a gear on a shaft 11, to which latter.
motion is imparted in a manner presently explained. From this construction, it
will be seen that as the carriage B moves forward, the molten glass will be
positively forced through the hopper and will be deposited on the table in uniform
quantities:
'
Mounted on the main frame A is a motor E (preferably an electric motor), on the
shafte of which, a bevel gear 1 is mounted and is adapted to be made to rotate
with said shaft by means of a clutch e. Another gear wheel 2 is mounted on the
shaft e and is adapted to be made to rotate therewith by means of a clutch e
The clutches and 3 are operated through the medium of pivoted levers e³, e',
respectively. Motion is imparted by the gear 2 to mechanism for ruuning the
carriage B, while the bevel gear 1 imparts motion to mechanism for moving the
entire apparatus on the tracks in front of the annealing furnaces, both of which
mechanism will be presently explained. As the carriage B and the operating
mechanism will not be in operation while the entire apparatus is being moved, the
gears 1 and 2 will be brought into operative relation to the main shaft e, in a
sense, alternately, and for this reason, both pivoted levers and et are pivotally
connected to the same operating lever e', a movement of which in one direction
will throw the carriage and operating mechanism into motion, and a movement of
said levere in the other direction will cause the entire apparatus to move on the
tracks a². A shaft 3 is mounted in the main frame A and at one end carries a bevel
wheel 4 adapted to receive motion from the gear 1. At or near the other end of the
shaft 3, a gear wheel 5 is secured and is adapted to impart motion to a gear wheel 6
secured on the shaft or axle a, thus propelling the apparatus. In proximity to the
motor shaft e, a shaft 7 is mounted in the frame A and at a point between its ends,
carries a gear wheel 8, adapted to receive motion from the gear wheel 2 on the main
sbaft e.
At the end of the shaft 7, gears.0, 9, are secured and adapted to mesh with
rack bars 10 on the bottom of the movable frame or carriage. A vertical shaft 11 is
mounted in the frame or carriage B and carries a pinion 12 adapted to receive motion
from a rack bar 13 secured to the main frame A, as the carriage moves along.
The shaft 11 carries a bevel gear 14 adapted to impart motion to a gear 15 carried
by the roller D. Thus it will be seen that as the carriage B moves along, the
roller D will be positively rotated and made to effectually roll the glass, while at the
same time, is being deposited on the table C by the hopper d, immediately in front
of the roller. 1 prefer to provide a duplicate the means above described for
rotating the roller D, at the other end thereof. For reasons which will appear
further on in this description, it is necessary that the roller D shall be raised off the
glass after having passed over it to roll it, and for the accomplishment of this, .
inclined blocks are pivotally connected to the main frame A at or near the end of
the table C. Two of these blocks will be employed, one at each side of the machine,
but as they and the devices connected to them are duplicates, a detail description of
one will suffice for both. At the free end of the block f, vertical rod flis pivoted.
and to the lower end of the rod f, one end of a lever is pivoted.. The lever f
is pivotally supported at a point between its ends in a groove or recess in the main
frame A and at its-free end carries a roller ³, the periphery of which projects to
the groove or way a³. The blocks are normally depressed so as to permit the
mechanism for ejecting the rolled and pressed glass plate, to pass over them, but.

page_text: when the roller D reaches the blocks at the end of its forward movement, it will
ride.on said blocks and thus be raised off or above the glass over which it has just
passed, the blocks being held rigid in their elevated positions by the flanges or
guides a of the carriage B, which will have become disposed over the rollers f³,
thus preventing any movement of the rods and levers connected with said blocks f
When the carriage B is moved back, the flanges or guides a will move off of the
rollers and thus release the blocks f, but it is not desired that the roller shall
thereby be allowed to again. make contact with the glass over which it has already
passed and therefore the devices now to be described will be employed for retaining
the roller in its elevated position. Bars g are located on the carriage B adjacent to
the journals of the roller D and are impelled toward said journals by means of
springs g. When the carriage B reaches the forward end of its movement and
the roller D rides up on the blocks f, the bars g will be forced under the journals of
the roller D and thus maintain it elevated until the carriage reaches its normal or
starting position, when a pivotal lever g projecting downwardly from the barg will
engage a ping projecting from the main frame A, and thus cause the bar g to be
withdrawn and release the roller D, allowing it to rest on incline g at the starting
point (see dotted line Fig. 1).
Carried by the movable frame or carriage B is a vertically movable table F
having face plates similar to those of the table C, said plates being provided with
minute perforations, the same as the face plates of the table C. The table Fis
provided with a series of guide bars / adapted to pass loosely through perforations
made in a bar or bars h' secured to the frame or carriage B. Screws F' are passed
through threaded perforations in the table Fand the bars and are adapted to
cause said table to have a vertical movement in the manner presently explained.
The screws are provided at their upper ends with bevel gears 16.adapted to receive
motion from similar gears 17 carried by a shaft 18 mounted in the frame or
carriage B. At one end of the shaft 18 a gear wheel 19 is secured and receives
motion from a gear wheel 20 mounted on a journal 21 projecting from the
carriage B. The gear wheel 20 receives motion from a gear wheel 22 carried by
the carraige B. A shaft 23 is mounted in the main frame A in proximity to one
end and carries a gear wheel 24 adapted to receive motion from a gear wheel 25
carried by the main shaft e. On the shaft 23 a bevel gear 26 is loosely mounted
and adapted to be made to rotate with said shaft by means of a clutch 27, which
is manipulated by a lever 28. The gear wheel 26 is adapted to transmit motion to
a bevel gear 29 secured to a short shaft 30.
Now when the carriage B shall have moved forward to the end of its movement,
and the roller D carried by said carriage shall have rolled the glass on the
table C, the upper table F will be directly over the plate of glass on the lower
table C, and the short shaft 30 will enter an angular opening in the gear wheel 22.
Should the clutch 27 be now operated to lock the gear 26 to the shalt 23, motion
will be imparted to the screws F¹, through the medium of the intermediate gearing,
and the upper table will thus be made to descend upon the glass on the lower
table C.
When the parts are in these positions, the hydraulic cylinders a' will be charged
with water through pipes i, by means of a pump G. Thus it will be seen that the
plate of glase, after having been rolled as above explained, will be subjected to
great pressure between the tables C and F, thereby rendering said plate of glass
compact, smooth.and clear.
The pump G is driven by a gear wheel 31 which is connected with the plunger
of said pump. The gear wheel 31 receives motion from, a gear wheel 32 mounted
loosely on the shaft 23. The gear wheel 32 is adapted to be made to rotate with
the shaft 23 by means of the clutch 27, which is operated by means of a lever 28:
At the forward end of the main frame A a carriage H is located and provided
with flanges or guides į adapted to run in the grooves a³ in the main frame A.
The carriage H is made with an arm respectively at both sides from which
a pin projects, and with this pin the hooked end of an arinj, pivoted to the

page_text: carriage B is adapted to engage when the latter reaches the forward end of its
movement, so that when the carriage B moves back to its normal position, the
carriage will move back with it for a purpose which will be fully explained
further on.
Mounted in the main frame A and extending to a point in proximity to the
forward end thereof, is a shaft 35, having a groove 36 running its full length or
approximately its full length. The shaft 35 is provided at one end with a hevel
gear 37 adapted to receive motion from a bevel gear 37ª on the end of the main
motor shaft e. On the shaft 35, two bevel gear wheels 38, 38, are loosely mounted
and between these gears, a clutch 39 is located and adapted to be operated by
means of a lever 40, whereby to lock either of said gears to the shaft 35
This
clutch is provided with a spline adapted to enter the groove 36 whereby it is
rotated with shaft 35, but is free to slide thereon. A vertical shaft 41 is mounted
in the carriage H and at its lower end carries a bevel gear 42 adapted to imesh
with the gears 38, 38. At the upper end of the shaft 41 a bevel gear 43 is located
and adapted to mesh with a bevel gear 44 on a horizontal shaft 45 mounted in the
carriage H. On the other end of the horizontal shaft 45 a bevel gear 46 is
secured and adapted to mesh with a bevel gear 47 at the upper end of another
vertical shaft 41 mounted in the carriage H. Ou each vertical shaft 41, 41, ak
gear wheel 48 is secured and adapted to mesh with the rack bare 13 carried by the
main frame A. From this construction and arrangement of parts it will be seen
that when the vertical shafts 41, 41ª are rotated, the carriage H will be moved
arcording to the direction of rotation of said shafts which will be governed by
means of the clutch 39.
Two bevel gears 49, 49, are also mounted loosely on the shaft 35 and between
them a clutch 50 is located, said clutch being adapted to be operated by means of
a lever 51. A vertical shaft 52 is mounted in the carriage H and at its lower end
is provided with a bevel gear wheel 53 adapted to mesh with the bevel gears 49, 49.
A bevel gear 54 is secured at the upper end of the vertical shaft 52 and meshes
with a bevel gear at one end of a shaft 55 having a double screw thread. Mounted
on the double screw threaded shaft 55 are nuts 56 having arms 57, and pivotally
connected to said nuts is a frame 58 in the form of lazy tongs, having a horizontal
slotted bar 59 at its forward end. The lazy-tong frame 58 is maintained in a normally
inoperative position by means of a cam 60 adapted to engage the arins 57 of the
nuts 56, said cam being carried by a shaft 61, having a wheel 62. by means of which
to operate it.
From the forward end of the main frame A an arm k projects (one on each side)
and to this arm, a table I is pivotally connected the normal position of said table
being that shown in dotted lines in Figure 1, when in use.
When the carriages B and H are moved backwardly, as above explained, an arm
projecting downwardly from the hook-shaped arm will engage a pin m, when the
carriage Breaches the rearward extremity of its movement, thereby disengaging the
carriage H from the carriage B. The apparatus will be rau on the tracks a² until
it is directly in front of the door, of an annealing furnace, when the table I, will
be turned down and made to enter the oven and thus constitute a way or slide
whereby to facilitate the insertion of the glass plate into the furnace.
The shaft 41 will now be put into operation by means of the clutch 39 as above
explained. The carriage H will thereby be made to move forward, the lazy-tong
frame pushing the rolled and pressed glass plate (which has been previously raised
by the hydraulic devices) before it. In order to force the plate of glass com-
pletely into the furnace, the shaft 52 will be made to rotate by the manipulation of
the clutch 50, and the shaft 55 thereby made to rotate and cause the lazy-tong
frame to be distended, as will be readily understood, thus forcing the plate of glass
completely within the furnace.
The apparatus is now ready for a repetition of the above described operations
for rolling and pressing a plate of glass and the insertion of the same into the
annealing furnace.

page_text: While my improvements may appear at first glance to be more or less complicated,
they are in fact, very simple, and by their use, a glass plate having great density,
:smoothness and clearness can be produced without the necessity of successive
trolling and without the necessity of turning the plate being operated upon.
By my improvements, the rolled and pressed glass plate will be easily, quickly
and effectually inserted into the annealing furnace withont the necessity of
handling it.
On the whole ny improved apparatus is efficient, in every respect, in the per-
formance of its functions.
