SPECIFICATION forming part of Letters Patent No. 541,737, dated J une 25, 1895.
Application filed March 22, 1894. Serial llo- 504,742. (No model.) I
To ttZwwm/t may concern.:
Be it known that I, JOHN GALT, of the city of Toronto, in the county of York and Province of Ontario, Canada, have invented cer tain new and useful Improvements in Hot- Water Boilers; and I hereby declare that the following is a full, clear, and exact descriptionfire pot water section, when the fire pot was' employed as such, were the sections that were subjected to the direct radiation of the heated products of combustion Within the -combustion chamber, with the consequent result that a very large percentage of the value ot the heated products of combustion was lost to the i heater. This loss may be explained in the following manner: The water within the first water section being subjected to a more intense heat than the water in any of the remaining water sections circulates much more rapidly than the water in any of the said remaining water sections, with the result that the force of the passage of the water from A this trst water section into and through the outflow partially chokes or arrests the passage of the Water from the remaining water sections into the same outflow, materially restricting and affecting the proper circulation ofthe water through the apparatus, and reducing the value ot' the apparatus as a heater. In addition to the foregoing defects it might here be stated that where the products of combustion are caused to circulate from section to section only in their upward direction, only a small percentage of the heat which they contain is absorbedby the respective water sections, and the available heat of the products of combustion failing to` be absorbed by the respective water sections, passes from the heater upward to the outlet to the chimney, and is Wasted. As the-heated products of combustion rise toward the top of the heater their motion becomes more rapid,
owing to the fact that little or noobstruction is oered to their passage, with theresult that the intermediate and topmost waterl sections have the opportunity of absorbing but a very small percentage of the heat 'fromy the products of combustion, thus rendering the boiler dependent to a very large extent upon the lowermost water sections for its heated water supply. In allot those heaters which I have had the opportunity of investigating the water sections each discharge into the outflow or head, usually locatedo'n the outer side of the water sections, and as At'ar remote from the heated products ot` combustion and the combustion chamber as possible, and still remain an inseparable part of the heater; thus compelling the heater to depend' almost entirely lon the first Water section for the force of thev circulation or discharge through the outlet pipes.
In all of those hot water boilers heretofore presented to the public thetop of the heaterhas generally been a metallic plate having an voutlet for the heated products of combustion p to pass .through during their course to the outlet to the chimney.
In all of those heaters which I have had an opportunity of examining the course of the products of combustion has been an upward one from the combustion chamber, to the outlet to the chimney.
YIt is the object of this invention to devise a heater in which the course of the heated products` of combustion will be upward to the topmost water section, and then downward to the first water section above the combustion chamber, in order that those heated products of combustion will operate directly upon the head or delivery section to give a rapid circulation or discharge through the outflow pipes, and provide aproper circulation of water through the respective Water sections of the heater. To accomplish this I haveA designed the heater as hereinafter more fully described and more particularly set forth in the claims, and illustrated in the accompanying drawings.
In the drawings, Figure 1 is a vertical sectional view otmy heater. Figs. 2 and 3 are similar views taken at right angles to the line on which Fig. l is taken to illustrate the outiiow and inflow. Fig. et is a viewof an alternative form.
Like letters of reference referto like parts throughout the specification and drawings.
A refers to the fire pot water section, B the combustion chamber, C the first water section above the fire pot, D the topmost water sec tion, and E the water sections intermediate between the first Water section A and the topmost water section D.
It will be noticed by reference tothe drawings that the water section C is located above and in circulation with the tire pot wat-ersection A, and that the intermediate water sec.- tions E are located one above the other, and are in circulation with each other, and with the first water section C and topmost water section D.
By reference to Fig. l of the drawings it will be noticed that a direct passageway F is formed centrally through eaehof the water sections C and E, and forms the means of` communication from the combustion chamber B to a secondary chamber G, located below the topmost water section D. The side walls of the direct passage F close off commu-` nication from the said direct passageway F and the chambers between the intermediate` to the same degree as-the first water section A, to cause a rapid circulation of the water in the said topmost water section, and provide a proper and rapid circulation of water through the outfiow pipes H. The outflow pipes -I-I are directly connected to the topmost water section D, and are consequently in direct circulation with the water within the said water section, instead of being connected to a head located on the outer side of the heater, as has heretofore been the case. The gases after ascending to the secondary chamber are directed downwardly from the secondary chamber through each of the intermediate water sections E, and caused to circulate through each of the chambers I between the respective intermediate Water sections before reaching the outlet J to the chimney.
By providing the heater with a direct passageway from the combustion chamber to a` secondary chamber immediately below the topmost water section, the topmost water section can be heated nearly to the same degree as the said water section above the combustion chamber, and by directing downwardly the gases and heated products of combustion from the secondary chamber throughV the` chambers I between the respective intermediate sections, all of the heat can be absorbed by the water in the respective water sections before reaching the outlet" to the chimney.l
In addition to the utilization of all of the heat, a proper circulation of the water within the heater can be kept up, and the circulation of the water from each of the intermediate water sections into the top and outflow section will not be interfered with by the circulation of the water from any of the other water sections into the same outflow.
In order to facilitate the starting of the fire within the combustion chamber I provide the `combustion chamber with a direct passage K from the combustion chamber to the outlet J to the chimney. This direct passage K is closed by a damper plate L operated by a lever M. In the starting of a fire within the combustion chamber the damper plate L is `moved to open the direct passage K from the combustion chamber B to the outlet .I to the chimney, and after the fire has received sufficient headway the damper plate L is moved to close the direct passage K, and cause the products of combustion to pass from the combustion chamber B to the outlet to the chimney J by means of the direct passage F, secondary chamber G and chambers I between the respective sections.
By reference to Fig. 2 of the drawings it will be noticed that the boiler is provided at its side with an outfiow N, and an inflow O. Each of the intermediate sections E is provided with an upwardly curved lip P extending into the outflow N, and the lip P on the lowermost of the intermediate sections E is longer than the lip P on the next adjacent of the intermediate sections E, in order that the lip P of the lowermost of the intermediate sections will direct the outflow of the water from the first sections C against the outer side of the outflow N, and prevent the circulation of the water from the said sections C interfering with the circulation of the water from the first intermediate section into the said outfiow N. It will also be noticed by reference to Fig. 2 of the drawings that a suf-` ficient clearance is left between the lips P of the intermediate sections and the outer wall of the outow N, to permit of the free circulation of the Water in the said outflow. The lip, P on the next adjacent of the intermediate sections E isslightly shorter than the lip P on the first of the intermediate sections E, and this reduction in the length of the lips P continues until the topmost of the intermediate .sections is reached. Each of the sec tions E and C at the opposite side of the heater is provided with a lip Q extending outwardly into the inflow O. The lip P on the section vC is the shortest of the lips Q, or, in other words, extends the least distance into the inflow O. The lip Q, on the lowermost of the intermediate sections is slightly longer than the lip Q on the section C, the lips increasing in length as the sections are more remote from the first section C, in order that each lip will `have an opportunity of directing the water into its respective section, without interfering with any of the lips above it, and without receiving any interference from those lips below it.
