BOILER.
SPECIFICATION forming part of Letters Patent No. 664,534, dated December 25,1900.
Application filed April 12, 1900. Serial No. 12,568, \No modeL To ctZZ whom it nutty concern:
Be it known that I, THOMAS P. CONNELLY, a citizen of the United States, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and Improved Boiler, of which the following is a full, clear, and exact description.
The object of the invention is to providea new and improved boiler which is simple and durable in construction, provided with a large heating-surface, and arranged to permit of conveniently and quickly removing a defective boiler-tube without disturbing any of the other tubes.
The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.
A practical embodiment of the invention is represented in the accompanying drawings,
forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 is a sectional side elevation of the improvement. Fig. 2 is an enlarged sectional side elevation of the upper end of one of the tubes in position in the bottom of the steamcompartment. Fig. 3 is a similar view of the lower end of the tube in the top of the watercompartment.
The improved boiler is provided with a suitable fire-box A, surrounded on the sides and top by a Water-compartment B, having its top B connected by water-tubes O with the bottom D' of a steam-compartment D, all inclosed in a shell E, having the usual smokeoutlet F. The throat A of the fire-box A opens centrally through the top B of the water-compartment B into a central space formed by the innermost row of tubes 0, and a suitable distance above the throat A is arranged a baffle-plate G, supported by a rod G from the bottom D of the steam-compartment D, as is plainly indicated in Fig. 1.
The smoke and gases passing from the firebox A through the throat A into the said central space are deflected by the battle-plate G and pass between the tubes 0 to the shell E and then travel upward until deflected inward by a baffle-plate H in the shape of a frustum of a cone the base of which is secured to the inner surface of the shell E.
The apex end of the baffle-plate H extends close to the outer row of tubes 0, so that the rising smoke and gases are forced in an inward direction between the tubes to the central space and under the bottom D, to then pass outward into the space between the steam-compartment D and the shell E, and finally rise to the outlet F.
As illustrated in the drawings, the tubes 0 are curved, and the top B and the bottom D" are dished toward each other, the ends of the tubes extending approximately at right angles to the said top and bottom. The openings for the tubes in the top B correspond to the diameter of the tubes, while the openings in the bottom D are somewhat larger than the diameters of the tubes, so that when the tubes are inserted in said top and bottom then the upper end of each tube is made bellshaped, as at C, to fit the tube snugly into the opening in the bottom D. (See Fig. 2.) The lower end 0 of each tube is projected beyond the under side of the top B and is then flangedoutward, as is plainly shown in Fig. 3, to securely hold the tube in place.
The curvature given to the tubes Q is such that when a tube is loosened at its lowerend C then the operator can slide the tube upward through the steam-compartment D and through the manhole D therein, whereby the tube can be conveniently removed from the boiler in case it becomes defective, it being understood that all that is necessary to loosen the tube is simply for the operator to enter the water compartment B (when empty) through the manhole B and to press the flange 0 back into circular shape, after which the tube can be moved upward through the steamcompartment and a new tube can be inserted, if necessary. it
' As illustrated in Fig. 1, four circular concentric rows of tubes 0 are shown; but it is evident that a greater or lesser number of rows maybe employed, if deemed necessary,
and the outermost tubes may be moved di-.
rectly without sliding the same through the compartment D upon first removing the shell to give access to the outermost row of tubes.
It is understood that the water readily circulates from the water compartment B through the tubes G into the lower portion of the steam-compartment D, and the steam is taken from the steam-compartment in the usual manner.
Having thus fully described my invention, I claim as new and desireto secure by Letters Patent- 1. A boiler having steam and water compartments, and tubes connecting the same with each other, said tubes being curved and the bottom of said steam-compartment and the top of said water-compartment being dished toward each other, the ends of the curved tubes being approximately at right angles to said top and bottom, as set forth.
2. A boiler comprising a steam-compartment, having a manhole in its top, a watercompartment, and tubes connecting said compartments with each other, said tubes being curved to permit of removing the tubes through the manhole in the top of the steamcompartment, substantially as shown and described.
3. A boiler'havi'ng a steam-compartment provided with a manhole in its top, a watercompartment, and tubes connecting said compartments with each other said tubes being curved to permit of removing the tubes through the manhole, the bottom of said steam-compartment and the top of said watercompartment being dished toward each other and the .end of the tubes extending approximately at right angles to said top and bottom, and baflie-plates for deflecting the smoke and gases, substantially as set forth.
4. A boiler having a steam-compartment, a water-compartment, and tubes connecting said compartments with each other,said tubes being curved to permit of removing the tubes through a manhole in the top or the steamcompartment, the tube-opening in the bot-v tom of the steam-compartment being someee4,5s4
compartments with each other and arranged in concentric circular rows to form a central space into which opens the fire box, a boilershell surrounding said tubes and steam-compartment and forming an outer space with the same, a baffle-plate in the central space above the throat of the fire-box, and a baffleplate, in the form of a frustum of a cone, and secured with its base to the shell above said central battle-plate, substantially as shown and described.
6. A boiler, com prising a fire-box, a watercompartment surrounding the 'fire box, a steam compartment, tubes connecting the compartments with each other and arranged in concentric circular rows to form a central space into which opens the fire-box, a boilershell surrounding said tubes and steam'compartment and forming an outer space with the same, a bafiie-plate in the central space above the throat of the fire-box, and a baffleplate in the form of a frost-um of a cone and secured with its base to the shell above said central bafiEle-plate, the apex end of said coneshaped baffle-plate reaching to the outermost row of tubes, as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. 1
