ENAIVIELING-KILN.
SPECIFICATION forming part of Letters Patent No. 774,478, dated November 8, 1904. Application filed August 19, 1904. Serial No. 221,400. (No model.)
T all whom it may concern.:
Be it known that I, JOHN S. JoBn, a citizen of the United States, residing at Monaca, in the county of Beaver and State of Pennsylvania, have invented or discovered certain new and useful Improvements in Enameling-Kilns, of which improvements the following is a specification.
The invention described herein relates to certain improvements in the construction of kilns for burning enamel-ware, the invention being' especially applicable to kilns for bathtubs, &c., and has for its object a construction whereby one of the kilns may be maintained at a higher heat than the other.
The invention is hereinafter more fully described and claimed.
In the accompanying drawings, forming a part of this specification, Figure 1 is a sectional plan view, the plane of section being indicated by the line I I, Fig. 2. Fig. 2 is a vertical section on a plane indicated by the line II II, Fig'. 1. Fig. Sis a similar view on a plane indicated by the line III III, Fig. 1, looking' in the direction of the arrow a; and Fig. 4 is a view similar to Fig. 2, illustrating a modification of my improvement.
In the practice of the invention it is preferred that the chambers A and B should be formed in the same structure and covered by a common arch 1, the chambers being' separated by vertical walls extending from the floor of the furnace to the crown of the arch, as shown in Figs. 2 and 4. These series of flues or passages 2, 3, and 4 are formedY under the Hoor of these chambers. One set of fines, 2, extend from one side of the furnace-` as, for example, the left-hand side or end in Figs. 1 and 2 under chambers A and B to uptake-fines 5 in the outer wall of the chamber B, the uptake-fines communicating with the chamber, preferably by perforations 7. The fines 3, preferably double the number of flues 2, extend from the opposite or right.
hand end of the furnace under the chambers B and A to the uptake-Hue 5lL in the outer wall of the chamber A, said uptake-fines communicating with the chamber A by perforations 7. The flues 4 extend from one end of the furnace under the chamber A and com- Inunicate with the uptake-flue 6 in the inner wall of said chamber and connected thereto near its upper end. Into the outer end of each of the ilues 2, 3, and 4 are inserted burners 9, which are connected to a supply-pipe 5 5 10. Combustion occurs at or near the entrance end of these flues, the air for such combustion being supplied through the air-ports 11. It will be seen from the foregoing that the bottom of the chamberA will be subject- 6o ed to the heat from a large number of the flues and that the side walls formed by the inner walls of the uptakes 5 .and 6 are heated, respectively, by the products of combustion from a large number of the passages or combustion-chambers. Hence this chamber will be more highly heated than the chamber B, which is employed as a drying-chamber, and is heated by the products of combustion from three of the combustion chambers or passages 7o along' its outside Wall and by the radiated heat from nine passages under its floor. The products of combustion escape from these chambersthrough ports 12 into the downtake-flues 13, which communicate at the lower 7 5 ends with the horizontal flue 14 and a vertical uptake 15 connected to the stack.
In the construction shown in Fig'. 4 the floor- flues 2, 3, and 4 are arranged as in Fig. 1 and connecting, respectively, with the up- 80 takes 5, 5I, and 6, the latter forming the separation-wall between the chambers. This uptake-liuc 6EL communicates at its upper end directly with the stack, and ports 16 are formed through its walls for the escape of products of combustiony into the uptake and thence to the stack. In this construction, as in that shown in Figs. 1 to 3, the-chamber A will be much more highly heated than the `chamber B, the latter being employed as the heating-chamber and the former as a burning or finishing chamber for the enamel. The charging-openings into these chambers are closed by double doors, and provision is made. for simultaneously swinging the doors of each chamber. To this end the doors are secured to vertical shafts 17, provided at their lower en ds with beveled pinions 18, adapted to interlnesh with pinions 19 on a rotating shaft or sleeve. In order that both sets of doors may be operated from one end of the furnace, the pinions 19 for the chamber A are mounted on a sleeve 20, supported in suitable bearings in the front of the furnace. The shaft 21 passes through the sleeve 2O and has the pinions 19 for the doors on chamber B secured thereto. It will be understood from the foregoing that by operating either one of the handles 22 or 23 either set of doors may be opened at will.
I elairn herein as my invention- 1. An enanieling-kiln having in combination two chambers, two series of iiues or oornbustion-passages passing from the ends of the kiln and Connected to the oharnbers at the opposite ends, one of the series consisting of a larger number than the other series, an uptake between the chambers and a series of ilues or combustion-passages extending under one chamber and connected to the central uptake, substantially as set `forth.
2. An enameling-kiln having in combination two chambers, each having uptake-dues along their end Walls, two series of combustion lues or passages extending from the ends of the kilns to the uptakes at the opposite ends of the kiln, an uptake between the chambers and a series of iiues or passages extending under one Chamber and connected to the Central uptake, substantially as set forth.
3. An enarneling-kiln having in Combination two chambers, each having uptake-fines along their end walls, two series of combustion lines or passages extending from the ends of the kiln to the uptakes at the opposite ends of the kiln, an uptake between the chambers and connected thereto and to the stack and a series or' fines or passages extending under one chamber and connected to the Central uptake, substantially as set forth.
In testimony whereor1 I have hereunto set iny hand.
JOHN S. JOBE.
