Improvements in Glory-hole Furnaces.
We, CARL WILHELM RICHARD GVERISCH, of 2, Planenscherplatz, Dresden, Ger-
many, Manufacturer, and PAUL JOHANN EISENSTUCK, of 37, Rodeberger Strasse,
Dresden, Germany, 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 following statement:-
Our invention has reference to improvements in glory-hole furnaces or fire
chambers in which hollow glass ware, such as goblets, tumblers, lamp chimneys
and the like, is reheated for melting the edges and for decorating it.
We provide beneath the furnace or fire-chamber proper a horizontally re-
voluble frame, carrying on its circumferential rim the standards or spindles upon
which the glass articles to be finished are placed. While the revoluble frame is
in motion these standards are subjected to a planetary motion, going around with
the revoluble frame and being revolved at the same time around their own axis.
In order to allow of glass articles of different heights being treated, we provide
means to raise or lower the fire-chamber proper, the glass ware standards keep-
ing their relative position.
In order to make our invention more readily understood, we have illustrated
it on the accompanying two sheets of drawings, Fig. 1 of which represents a plan
view of a part of the arrangement, part of the furnace top being broken away, to
show the glass-ware standards.
Fig. 2 is a side view of part of the arrangement partly in section.
Fig. 3 is a detail side view with the fire chamber in section, showing the man-
ner of attaching the standards to the revoluble frame rim.
The segmental shaped fire chamber is constructed of refractory brick or the
like and is open at the bottom. Two sets of burner pipes q. r discharge a mixture
of gas and air from the top of the fire chamber downwards, the flame bending
and burning parallel with the top of the fire chamber. Two other sets of burners
s and are led into the side of the fire chamber and are used for decorating the
A
glass ware after it has been melted and fire polished by the burners q & r.
horizontally revoluble frame, consisting of the arms or spokes m and the circular
rim n is mounted upon the vertical axle k which beneath the frame carries the
toothed wheel 7. The arms m are of such length as to bring the rim n under-
neath the fire chamber. Upon this circular rim na number of carriers o are ar-
These carriers serve as
ranged, preferably secured by means of set screws o¹.
bearings for the revoluble standards or spindles ¹, which extend into the fire
chamber and are provided with cylindrical blocks 2 upon which the glass
articles to be heated are placed. Upon the axle of these standards chan-
nelled pulleys are fastened. Endless strings or thin wire ropes are placed
around the pulleys of all the standards, which strings or wire ropes run over the
tightening bullers . the driving pulleys and the guiding pulleys. If now
the revoluble frame is set in rotary motion the standards will be carried through
the fire chamber and at the same time will be rotated around their own axis.
The driving pulleys are fastened uron the shaft f which is geared with the
main shaft c. This latter. boving the fast and lense pulleys a, b, transmits is

shaft d.,, 22 are tightening pulleys. Upon the shaft d the endless worm h is
arranged meshing with the toothed wheel 7. The revoluble frame is supported
by rollers a
Within the fire chambers » a flame deflecting plate p¹ is arranged for deflect-
ing the flame from thin glasses, in order to prevent their collapsing under
excessive heat. This deflecting plate, shown in Fig 3, can be operated in any
desirable way.
In order to adjust the position of the fire chamber according to the varying
height of the glass ware, we attach the fire chamber to a shaft z by means of
stays The shaft is screw threaded as at 7 and by operating the internally
screw threaded hand wheel y, the shaft and with it the fire chamber can be raised
or lowered to the desired position.
This adjusting arrangement is only shown in Fig 2.
dis a crank for turning the shaft by hand.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what
wo claim is:-
1. In a furnace for heating, melting and decorating glass ware the combina-
tion of a segmental shaped fire chamber, being open at the bottom, a revoluble
frame, arranged below the fire chamber and carrying on its circular rim verti-
cally revoluble standards or spindles, extending into the said fire chamber means
for rotating the said frame and means for rotating the said spindles, indepen-
dently of the frame motion, substantially as set forth.
2. In a furnace for heating, melting and decorating glass ware the combination
of a segmental shaped fire chamber and means for raising and lowering the said
fire chamber, consisting of the stays 21, the shaft and the handwheel y, as and
for the purpose set forth.
ہے
3. In a furnace for heating, melting and decorating glass ware the combination
of a segmental shaped fire chamber, and the flame deflecting plate 1 as set forth.
4. In a furnace for heating, melting and decorating glass ware the combination
of a segmental shaped fire chamber, being open at the bottom, a revoluble frame,
to the circular rim of which are secured by means of set screws carriers for the
vertically revoluble spindles, the latter having channelled pulleys provided upon
their axle, tightening pulleys, guiding pulleys and driving pulleys, strings or
wire ropes running over all the said pulleys and means for rotating the said
driving pulleys, as and for the purpose specified.
5. In a furnace for heating, melting and decorating glass ware the combination
of the segmental shaped fire chamber being onen at the bottom and having the
flame deflecting plate p¹, stays z¹. shaft z and handwheel y, the horizontally re-
voluble frame, carrving upon its circular rim n. the carriers o for the axles of the
standards or spindles r. set screws o¹, circular blocks and pulleys the
vertical axle k. the toothed wheel 7. the endless worm h and the shaft receiving
its rotary motion from the main shaft c. this latter to be geared to the vertical
shaft f. carrying at its upper end the driving pulleys u, the tightening pulleys w,
the guiding pulleys w¹, endless strings or thin wire ropes, running over all the
said pulleys and rim supporting rollers a', the parts being constructed arranged
and working substantially as set forth.
