Improvements in Glass Dipping Machines.
I, CHARLES EDWIN BLUE, of 33, 18th Street, Wheeling, in the County of Ohio
and State of West Virginia, United States of America, Inventor and Manufacturer,
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 fol-
lowing statement:-
This invention relates to improvements in glass dipping machines and has for
object to provide a mechanism adapted to take a charge or quantity of glass at one
point and to automatically deliver it at another point.
In the accompanying drawings,
Figure 1, is a front elevation of a glass dipping machine embodying my inven-.
tion, the operating lever or pendulum shown in a vertical position in full lines,
and in its opposite positions in dotted lines.
Figure 2, is a vertical sectional view of Figure 1.
Figure 3, is an enlarged detail view of the cam operating the air controlling
valve through the medium of an arm or lever.
Figures 4, and 5, are detail views of the air controlling valve.
Referring now to the drawings, A indicates the glass mold, or other point at
which it is desired to deliver a quantity of glass, B a funnel situated thereabove,
Ca glass pot containing a quantity of molten glass, and D a water tank adapted
to receive the ladle or glass carrying receptacle and cool the same after it has
delivered the glass to the desired point.
E are hangers or supports, F a driving shaft, and G a cone-pulley receiving its
power through a belt from any desired source. It will be readily understood that
means other than a belt and pulley may be provided for driving the shaft F with-
out departing from my invention. Attached to one end of the driving shaft F is
a crank H carrying at its outer end a roller or wrist pin I. J is a lever or
pendulum carrying at its upper end a disk M. said lever or pendulum being inter-
mediately pivoted and supported upon a bolt K supported by a hanger L.
The disk M is provided at opposite sides of its center with are-shaped
grooves N, said grooves being united by means of the upwardly and, downwardly
projecting recesses O and O₁ respectively.
Carried upon the lower end of the lever or pendulum J is a cylinder i containing
the piston to which is connected a piston rod & carrying at its lower end a glass
ladle or other receptacle 7. m is a cover adapted to close the said ladle, pivoted at
the point n and having connected therewith a curved arm p having a correspond-
ingly curved or cam slot 7 which receives a pin or screws carried by the cylinder i.
Secured to the driving shaft F is a cam T provided with the cam surfaces a,
b and c, the function and operation of which will be fully described hereinafter.
Attached to one of the hangers or supports E is a casting Q through which passes
a valve e, the casting having a chamber or-recess R adapted to register with air
passages made in the said valve e. Connected with the casting are the pipes f
and which communicate respectively with the upper and lower ends of the
cylinder i above and below the piston head j, the upper ends of these flexible

page_text: pipes being in communication with the air chamber R of the casting through the
passages of the said valve e. Attached to the valve e is a lever or arm d adapted
to be engaged and operated by the cam surfaces a, b, and c in a manner to be
hereinafter set forth. Attached to the valve e is a spring u of any desired form,
constructed to cause the free end of the arm or lever d to be in constant engage-
ment with the cam as it revolves, the said cam serving to force the arm outward
and the spring to hold it in engagement therewith.
The piston head carrying the ladle is adapted to be moved up and down by
means of air pressure, which is fed to the chamber R of the casting Q through the
communication S from any desired source. When ladle or receptacle is drawn
upward, the cover m is moved over and closes the ladle or receptacle through
the medium of the cam or curved slotted arm p and the stud or screw s; and when
the ladle is lowered the cover is removed therefrom, both movements being clearly
illustrated in Figure 1.
The device is adapted to take a quantity of molten glass from one point and
deliver it to another point. For instance as illustrated in Figure 1 to take from
the glass pot C a quantity of glass, carry it over the mold A, deliver the glass
within the mold; in moving backward to pass into the water tank D and be
cooled, and thence to the glass pot for again being charged. When the ladle
or receptacle is over the glass pot C, it is carried down within the glass, and its
downward movement causes the removal of the cover of the ladle when the ladle
becomes filled, and moving upward again closes the said receptacle thus removing
from the glass pot filled with glass. The ladle then remains in this upward closed
position until it arrives over the mold as shown in Figure 1, when the ladle is
moved downward and in its downward movement causes the cover to be removed
and deliver the glass to the mold as will be readily understood.
The apparatus subjects the ladle to a cooling agent after discharging and before
the charging thereof, and this is very essential, for otherwise the glass would
adhere to the ladle, and make it practically inoperative for the purpose described.
I do not therefore limit myself to the particular mechanism here shown for
accomplishing this end, for this may be varied and changed, without departing
from the spirit and scope of the claims to this part of my invention.
Carrying these steps in mind, the operation of my invention is as follows;-
Taking the position shown in solid lines in Figure 1, with the ladle down, and
the arm engaged by the cam surface c, both of the air passages to the cylinder i
are closed; the wrist pin or roller I is within the lower recess 0¹, and as the
crank H revolves in the direction indicated by arrow, the ladle is carried to the
left. In moving to the left it engages the incline r of the water tank and is
moved upward and drops within the water and passes therethrough and just before
it reaches the opposite wall of the water tank, the cam 6 engages the arm & thus
actuating the valve and opens the air passage to the lower part of the cylinder
thus elevating the ladle or receptacle. The lever or pendulum J continues to
move to the left to about the point shown in dotted lines at which point the
disk M has become sufficiently tilted to cause the roller or pin I to pass out of
the recess O¹ and into the arc-shaped groove N at the right of the disk M. The
pendulum then ceases its lateral movement owing to the fact that the pin or
roller moves in the arc-shaped grooves thus holding the ladle in this position until
the pin
or roller reaches the recess 0 at the top of the disk M. While the roller is
passing from the recess 0¹ at the bottom of the disk M to the recess ( at the top
thereof, the arm d is actuated by the cam surfaces of the cam T to, cause the
admission of air at the top of the cylinder i forcing the ladle downward in the
glass pot and then to remove it immediately therefrom by the quick and succes-
sive movements of the arm d through the medium of the cam surfaces b and a.
The movement of the ladle within the glass opens it as before described, and the
movement of the ladle therefrom closes it as before described SO
that the ladle is removed from the glass pot filled with glass, and the
arm d is then upon the long cam a. At this point, as before stated, the roller I

page_text: has reached the upper recess of the disk M and in passing within the said
recess of the disk M and in passing within the said recess the pendulum or
lever J is moved in the opposite direction and passes over to the position shown
in dotted lines at the right of Figure 1. When it reaches this position, the arm d
has reached the opposite end of the cam a, and the arm is permitted to be
drawn in by the spring, and in being drawn inward air is admitted to the top
of the cylinder i and the ladle moved downward over the mold and in its downward
movement the cover is removed therefrom and the glass deposited within the
mold. The downward movement of the ladle at the right hand side is accom-
plished while the pin I is in the arc-shaped groove at the left side of the cam M
and before it reaches the recess 0¹ at the bottom- thereof. When it reaches this
point, the ladle is reciprocated in the opposite direction and passes through the
water tank as before described. This operation is repeated, the glass being taken
from one point and delivered at another, as will be readily understood from the
above description.
The cam surfaces of the cam T, and the air passages in the valve E are so
situated that air is admitted and cut off from the upper and lower portions of the
cylinder I at the proper time to accomplish the operation herein described.
I do not limit myself to the exact construction shown, for these may be varied
without departing from the spirit and scope of my claims.
