EDWIN DE H. CALDWELL, OF ST. CHARLES, ILLINOIS, ASSIGNOR, BY 1VlI1EJSNE ASSIGN- MEN'IS, TO CI-IAUTAUQUA MOTOR COlJIPANY, OF DUNKIRK, NEW YORK, A CORPORA- TION OF NEW YORK.
STEAM-BOILER.
To all whom it may concern:
Be it known that I, EDWIN DE H. CALD- WELL, a citizen of the United States, residing at St. Charles, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Steam Boilers, of which the following is a specification.
My invention relates in general to steam boilers, and more particularly to a water tube boiler, especially adapted for use on automobiles.
In the operation of steam propelled automobiles it is necessary that boilers should be employed. which will be light and compact in construction, and which at the same time will quickly generate steam and maintain the requisite degree of pressure. It is, therefore, customary to construct such boilers of water tubes so that the greatest possible area of heating surface may be had within a given space.
The primary object of my invention is to provide a steam boiler by means of which a minimum consumption of fuel will quickly generate a high degree of steam pressure and which will be light and compact.
A further object of my invention is to provide a steam boiler which will be simple in construction, inexpensive in manufacture and efficient in use.
The embodiment of my invention herein disclosed may be generally described as comprising a plurality of horizontal superposed series of convolutions, the convolutions in each series being formed by two intersecting sets of parallel tubes, the tubes in each set being connected at their ends to the ends of adjacent tubes in the other set, the several series of convolutions being connected to form a continuous conduit.
My invention will be more fully disclosed herein with reference to the accompanying drawing in which the same is illustrated in a convenient and practical form, and in which Figure l'is an elevational view, the inclosing casing being shown in vertical section; and Fig. 2, a plan view of one of the horizontal series of convolutions.
The same reference characters are used to designate the same parts in the two figures of the drawing.
Reference characters A to A, inclusive, designate series of convolutions located Specification of Letters Patent.
Application filed May 27, 1907.
Patented Jan. 24, 1911.
Serial No. 375,970.
[ within a suitable casing A and immediately above a suitable source of heat, such, for instance, as the gaseous fuel burner indicated by reference letter D.
The several sections of the boiler formed by the horizontal series of convolutions are united so as to form a continuous conduit through which the water passes from a supply conduit B to a steam delivery conduit.
Each section comprises two sets of parallel tubes, the opposite ends of the tubes in each set being connected with the ends of the adjacent tubes in the other set. By reference to Fig. 2 it will be seen that reference characters a to (.4 indicate the parallel tubes in one set while reference characters a to a indicate the parallel tubes in the other set, the tubes in the two sets being inclined with respect to each other, so that each tube in one set crosses a plurality of tubes in the other set. The ends of the tubes in the two sets at one side of the boiler are united by curved integral couplings Z) to b while the ends of the tubes in both sets at the opposite side .of the boiler are connected by integral couplings 12 to If". It will be observed that the sets of tubes and their integral curved couplings are so located as to form a series of overlapping convolutions, thereby forming a continuous conduit of great length compared to the area which it occupies.
' Reference characters B, B B and B indicate curved couplings uniting the corresponding ends of adjacent sections of convolutions at one end of the boiler, while ref erence characters B 13* and B indicate curved couplings uniting the ends of adjacent sections at the opposite end of the boiler. The couplings at each end of the boiler are staggered so as to extend to opposite sides of the center plane of the boiler, thereby occupying the same vertical planes so as not to increase the length of the boiler. The several sections or convolutions are duplicates, but in order that the end couplings may be staggered, the positions of the sections are reversed. It will be observed that sections A and A are inverted with respect to the higher sections and also with respect to the sections A and A while the section A is arranged in the same position as the section A*. The bottom section A is arranged in the same position as sections A and A, and inverted wlth respect to section A consequently the coupllng B ex tends in a downwardly inclined position from section A to section A. By thus in verting certain of the sections the end couplings are staggered and consequently eX- tend past each other, the couplings at each end of the boiler occupying the same vertical plane. The ends of the adjacent sections of convolutions are united in any suitable manner, as by means of sleeves having oppositely screw threaded ends, such as indicated by reference character Z).
It will be noted that the coupling 13 connecting the two lower sections A and A extends downwardly and does not extend upwardly to a point above the section A as the lower sections contain superheated steam and it is, therefore, unnecessary to form a trap. The couplings uniting the ends of the sections above the two bottom ones extend upwardly above the upper end of the united sections so as to form traps to prevent the gravitation of water to the lower of each of the connected coils. It will be observed that no means is provided for preventing gravitation to the lowest section, as there is no danger of gravitation to said section, owing to the two lower sections containing superheated steam.
From the foregoing description it will be observed that I have invented an improved boiler comprising a plurality of horizontal sections, each section comprising a plurality of overlapping convolutions, the sections being connected so as to form a continuous conduit through which water flows from a pump to the upper section and thence successively through the sections toward the burner.
It will also be observed that my improved boiler atlords a maximum area of heating surface within a minimum space without interfering with the draft upwardly around the tubes forming the convolutions in the superposed sections.
Having now fully described my invention, what I claim as new and desire to secure by Letters Patent, is
1. In a tubular steam boiler, the combination of a plurality of parallel sections, each section comprising a plurality of overlapping convolutions, and vertical coupling loops uniting the ends of adjacent sections to form a continuous conduit, the coupling loops at each end of the boiler being staggered.
In a tubular boiler, the combination of a plurality of parallel horizontal series of convolutions, each series comprising two sets of parallel tubes, the tubes in one set crossing the adjacent tubes in the other set and being connected at their ends to the corresponding ends of adjacent tubes in the other set, and couplings uniting one end convolution in each series to the corresponding end convolution in the adjacent upper series and the other end convolution in each series to the corresponding end convolution in the adjacentlower series.
3. In a tubular boiler, the combination of a plurality of horizontal parallel series of convolutions, each series of convolutions comprising two sets of parallel tubes, the tubes in one set crossing the adjacent tubes in the other set and being connected at their ends to the corresponding ends of the adja cent tubes in the other set, ind coupling loops uniting one end convolution in each series to the corresponding end convolution in the adjacent upper series and the other end convolution in each series to the corresponding end convolution in the adjacent lower series, the coupling loops at each end of the boiler being staggered.
