GEORGE E. MCOASKEY, OF MATTOON, ILLINOIS.
SPECIFICATION forming part of Letters Patent No. 515,441, dated February 27, 1894. Application filed November 21. 1893. fierial No. 491,566- (No model.)
To whom it may concern:
Be it known that I, GEORGE E. MoCAsKEY, a citizen of theUnited States, residing at Mattoon, in the county of Coles and State of Illinois,have invented certain new and useful Improvements in Furnaces; and I do declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to-make and use the same, reference being bad to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
Figure 1 of the drawings is a front elevation of a furnace embodying the invention. Fig. 2 is a rear elevation of the same. Fig. 3 is a top plan view with the boiler removed. Fig. 4 is a bottom plan view. Fig. 5 is a detail view in section of the grate and shaker on line a a; Fig. 3, and Fig. 6 is a transverse vertical section on line y y Fig. 3.
This invention has relation to certain new and useful improvements in smoke and gas consuming furnaces, and is designed to provide means in a furnace for effecting a more perfect combustion of the fuel, a large percentage of which in the ordinary furnaces passes ofi unconsumed; and the invention consists in the novel construction and combinations of parts, all as hereinafter described and pointed out in the appended claims.
Referring to the accompanying drawings the numeral 1 designates the furnace wall, and 2 the horizontal boiler supported by said wall in the usual manner.
In carrying out my invention, I divide the fire box of the furnace into two compartments being separated from each other by the partition wall 5 above described.
10, are the usual bridges, one at the rear of each of the fire boxes 3 and 4.
The upper and lower walls of the chambers 8 and 9 consist respectively of the transverse horizontal damper plates 11 and 12. In the upper plate 11 is formed an opening 13 over the chamber 8, and an opening 14 over the chamber 9, said openings leading into a common transverse chamber 15 above said chambers 8 and 9, and into which also open the boiler flues 16. By means of a sliding damper 17 either one of these openings 13 and 14 may be opened or closed at pleasure.
18, 18 are walls closing the spaces at each side between the fines 6 and 7, and the chamber 15, and compelling all the smoke and gases to pass into the chambers 8 and 9 from the said does.
In the lower flue plate 12 are formed two openings 19 and 20, situated respectively below the openings 13 and 14, and controlled by a sliding damper 21. Said openings 19 and 20 lead into a common, lower, transverse chamber 22 the forward wall of which consists of a Vertical damper plate 24'having therein openings 25 and 26 which communicate respectively with parallel, lower longitudinal flues 27 and 28, separated from each other by a partition wall 29 which extends to the front wall 30 of the furnace. Controlling the openings 25 and 26, is a sliding vertical damper 31. p
32, 32 are doors in the rear wall 33 of the furnace and giving access to the chambers 8 and 9 for cleaning, or other-purposes, similar doors 34, 34 being provided for the chamber 22.
35, 35 are the front doors to the respective fire boxes 3 and 4, and 36,36 are the doors to the ash boxes.
The operation is as follows :--Supp0sea fire to be built in the left-hand fire box 4, the dampers being arranged to close the opening 14, into the upper chamber 15, the opening 19 into the chamber22, and the opening 26 into the lower flue 28, and to expose the opening l enter underneath the grate 37 of the firebox 3, passing up through saidgrate and through the previously built and hot fire in said fire box where a second combustion ensues. The remaining non-combustible parts together with those from the second fire pass rearwardly through the flue 6, into the chamber 8, up through the opening 13 into the chamber 15, thence into the boiler fines 16, and forwardly to the stack 38. By simply reversing the dampers, the smoke and gases maybe made to pass from the fire box 3, around and through the fire in box 4 in a similar manner, so that by alternately feeding the two fires and reversing the dampers, a large saving of fuel may be effected. Or in one fire box I may maintain a hot fire of'coke, or other material burning with little smoke or gas, and arranging the dampers to pass the smoke and gases from the other fire to which coal is fed through this fire. In order to cause the returning smoke and gases to pass up through the central portion of the grate where the fire is hottest so that it is not necessary to keep a hot fire at the rear portion of the grate, the upper walls of the fines 27 and 28are extended forwardly underneath the grate as seen at 40, 40, said extensions being preferably inclined downward and forward as shown, and terminating underneath about the central portion of the grate.
In order to keep the grates from becoming choked with ashes to such an extent as to interfere'with the passage of the smoke and gases upward therethrongh, suitable devices may be employed. An effective device for thispurpose is shown in the drawings and consists of a bar 41 placed between each pair of grate bars and capable of a limited endwise sliding movement. These bars are all connected to a common frame 42 to which is attached a handle 43 which may be operated from the front of the furnace.
The openings in the damper plates should be. about'the same size as the fines, and the distance between the dampers 2-1 and 31 should be equal to the height of the flue.
44, 44 are small steam or Water pipes arranged to discharge a spray onto the smoke and gases at the rear as they descend into the chamber 22. Said pipes if desired might be placed at the front under the'fire box.
Having described my invention, what I claim as new, and desire to secure byLetters Patent, is
1. In a furnace, a longitudinally divided fire box and smoke fine, separate chambers at the rear into which the respective portions of the divided fine open, a common chamber.
above said separate chamber, and into which the boiler fines open at the rear, a common chamber below said separate chambers, pas sages from said separate chambers into said common chambers, dampers for controlling said passages, longitudinal return passages or fines leading from the lower common chamber forwardly underneath the grates, and means for closing either one of said return passages or fines, this arrangement of fines and dampers providing means whereby the smoke and gases of combustion from either fire box may be made to pass three times the length of the furnace and through the other fire before passing to the boiler fines, substantially as specified.
' 2. In a furnace, the combination of thefire boxes 3 and 4, fines 6 and 7, chambers 8 and 9 into which the respective fines 6 and 7open at the rear, the common chamber 15 above the chambers 8 and 9 and with which both said chambers communicate, a damper for controlling such communication, a common chamber 22 underneath the chambers 8 and 9, and with which they also communicate, a damper for controlling the openings into said lower chamber, the walls 13, 18, the lower fines 27 and 28 underneath the fines-8 and 9 and openingat the rear into the chamber 22 and at the front extended underneath the grates, and a damper arranged to control the communication between said fines 2'7 and 28 and the chamber 22, substantially as specified.
In testimony whereofI affix my signature in presence of two witnesses.
