GLASS-WORKENG FURNACE.
Specification of Letters Patent.
Patented Feb. 6, 1906.
Application tiled August 1,1905. Serial No. 272.177.
Be it known that i, Inn A. MiLLinoN, a citizen of' the United States, residing at Franklin,in the count y of Venango and State of Pennsylvania, have invented certain new and useful lm )rovements in Glass-Working Furnaces, of w lich the following is a ecification, reference being had therein to t ie accompanying drawings.
My invention relates to improvements in furnaces for working ulass, and will be fully understood from the ollowing` specification, reference bein f had to the accompanying drawings, whic 1 form a part hereof, and in which- Figure 1 is a plan view of my furnace. Fig. 2 is a central vertical section on line 2 2 of Fig. 1. Fig. 3 is a section on line 3 3 of Fig. l. Fig. 4 is a pers )active view of the furnace pro er dismounte from its housing.
l. e construction of my furnace is substantiallv as follows:
The furnace proper (shown in perspective in Fic. 4) is of rectangular form and is provided5 with trunnions 2 2, for which bearings 3 3 are provided in the housing 4, whereby the furnace is adapted to revolve vertically.
.The furnace has a heat-chamber 5, into which a blast of hydrocarbon vapor or gas and air is introduced through a passage 5', formed in the trunuions, for the purpose of heating said chamber. Above and below said heat-chamber is located a glass-recepta cle 6 6 with their bottoms in juxtaposition.
Beneath the revolving furnace 1 is placed a vertically-movable subfurnace 7, which constitut s a means of generating heat bcneath tl e furnace 1 and whereby the lower pot 6 is `heated simultaneously upon both sides thereof. Said subfurnace is so con# structed as to be capable of a vertical move ment and is equipped with suitable mechanism for so moving it, which mechanism consists of the levers 8 8, one at each side of the furnace. Said levers are )ivoted or fulcrumed at their center to tlie housing, and one end of each lever is attached to the subfirnace at opposite sides, as shown at a, Fig. 2, and the opposite end of each lever is attached to a cross-head 9, which is actuated by the piston-rod and piston 10 and 10. Piston 10 is seated in the vertical cylinder 1l,
which is closed at the upper end by a suitable head, and a pipe 12 enters said cylinder through the head, and by means of which pipe fluid under pressure-*such as steam, compressed air, or water-may be admitted above the pistonfor the pur )ose of forcing the same down to raise the sufifurnace. Any suitable valve Conni "ml used for the purpose (not shown) mayviiia placed in the pipe l2 to admit the motive agent to aml exhaust it from the cylinder 1l, which pipe l2 may lead to a suitable stealn-generator, air-rcn cciver, or pump. (Also not shown.)
When my furnace is in use, a blast of fuel i'rom )ipe l) is admitted to the chamber .3 to heat tlhe interior thereof, and more especially the glass-receptacles, to the required heal. A quantity of molten glass may then be placed in the upper receptacle and drawn therefrom into any desired product capable of beingso produced. When said quantity of glass is used up, the subfurnace 7 is lowered, as shown in dotted lines in Fig. 2, and the furnace 1 is then turned over by means of the hand-wheel W. Then subfurnace 7 is again raised and a heatfblast is admitted to the inf terior thereof through pi )e P and passage P, which heatblast is for the purpose of keeping the lower rece )tacle hot.
An urn 13 is placed 1beneath the furnace l and extends upward into the subfurnacc 7 and has at. the top thereof an enlarged head, which is for the purpose of holding any glass that may fall from the inverted receptacle and for the further purpose of closing the bottom of the subfurnace.
The essential elements of my deviceare substantially as above set forth; but in addition to these a few minor details will be dc scribed.
The piston-rod l() is extended below thcI cross-head, and said extension enters thc guide 14, which is f or the purpose of sustain- 1n the lateral strain upon thel rod when the su )furnace is being raised. Through guide 14 is drilled a hole, and a corresponding hole is also drilled through the rod 10 to register with thehole in the guide when the rod is at its lowest noint. A pin l5 may be placed in said ho es when in register for the purpose of locking the subfurnace in the elevated position, as the weight of said subfurn'ace would cause same to drop if the pressure above the piston 10 should diminish by leakage or accident. l
It will be readily understood that the locking of the subfurnace 7 in its raised position efectually prevents the revolving of fur- IOO nace l g bui/as an independent means of loeking said furnace l provide a bolt 16, which is sliding-ly mounted in a lug 17 u on the cap of one of the bearings, and said' olt 16 enters tho seat 18 in the side of the plate of the Jfurnace .1 and efectually locks the furnace in position.
Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is-
l, A glass-working furnace having a cen trai heat-chamber7 glass-receptacles located upon opposite sides of said chamberv with their bottoms in juxtaposition, and means of revolving' said furnace.
2. A vertically-revoluble glass-working furnace having an inclosed heat-chamber with means of admitting heat thereto, said chamber having glass receptacles located upon opposite sides thereof with their openings facing outward.
3. A glass-working furnace having glassrecoptacies in its top and bottom sides, a heat-chamber locateo between said receptacles, means of generating heat in said chamber, in combination with means of revolving smoes said furnace, and means of generating heat beneath the same.
4. A vertically-revoluble glass-worlring furnace having a plurality of glass-receptacles located in the Walls thereof, and means of generating heat between said receptacles.
5. The combination with a revoluble urnace having a central heatwhamber and the glassreceptacles located at opposite sides thereof, of means of enerating supplementary heat beneath sai furnace, means of'rev volving said furnace and. means of preventing the revolving of said furnace.
6. A revcluble glass-Working furnace having an interior heat-chamber the glass-receptacles located inthe walls of said chamber, m combination with a su plementary furnace, means of bringing sai supplementary furnace into proximity to said first-mentioned furnace and of renlovi 0* the same therefrom.
