LEE S. CHADWICK, OF EAST CLEVELAND, OHIO,
ASSIGNOBI'TO ,THE CLEVELAND METAL PRODUCTS COMPANY, OF CLEVELAND, OHIO, A. CORPORATION OF OHIO.
1 Application filed November To all whom/it may concern;
Be it known that I, LEE S. GHADWIoK, a citizen of the United States, residing at East Cleveland, in the county ofgCuyahoga and State of Ohio, have invented a certain new and useful Improvement in Water-Heaters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.
This invention relates to improvements in water-heaters, especially of the variety involving hydro-carbon burners; and the invention has for its objects. the economical production of a water heater, particularly of the above mentioned class, that is highly efiicient; comparatively simple of construction; and which may be thoroughly and easily cleaned.
To the ends of simplicity and cheapness,
I propose to use sheet metal, principally, for
the construction of the apparatus, and to employ, as far as practicable,elements that have become. standard in the art; such for instance, as the particular type. of burner employed, as well as the fuel supply and and water circulating Also I have designed the casing which incloses the water circulating device so that one .side may be conveniently and entirely opened to reveal the whole interiorof the apparatus, thereby-t0 facilitate inspectionand cleaning. As is more or less common in apparatus of this character, the casing is lagged with 'anon-heat-conducting material, the novel feature in this connection which the lagging is held in place and protected. In order to acquire the maximum efficiency, I preserve the established induced draft conditions of the burner by supplying the natural draft of the flue with atmosphericair ata given elevation above the burner. By thus satisfying the natural draft of the flue from outside air, the induced draft of the burner is left undisturbed, the arrangement allowing,
however,'the escape of the products of combustion through the flue. Objects in addition to those above enumerated are attained through certain structural details illustrated in the accompanying drawings and brought out in the folloW- I ing description. In the drawings, wherein similar reference characters are used to designate corresponding parts through the WATER-HEATER.
: Specification of Letters Iatent. Patented @431 14, 1919,

several views, Figure 1 is a front elevation of my improved water heater; Fig; 2 is a sectional' front elevation thereof; Fig. 3 is a horizontal section through the heater on the line 33 of Fig. 2and looking in the direction of the arrows; Fig.4 is a vertical section on the line 4- of Figs. 1 and 2; Fig.
5 is a detail of the stop for holding the movable side of the heater casing in elevated or open position; Fig. 6 is a vertical transverse section through the lower portion of a modified form of my heater; and Fig. 7 is a detail in perspective of the supply pipe connection with the base. j
The embodiment of'my invention illustrated in Figs. 1 to 5 comprises a cylindrical casing 1, preferably of sheet metal, that is made up of a stationary rear side 1 and a movable front side 1 the stationary side having secured to its upper end a circular cover 2, and-to its lower end, a ring 3. The casing is preferably lagged with a non-heat conducting material as will bepresently explained. The cover has a right angle peripheral flange 2 within which the upper end of the side 1 reposes and to which it is attached by fastening means, such as bolts 4. The enlarged upperend of the ring 3 constitutes a flange 3* into which the lower end of the side 1' of the casing'is'inserted and to which it is attached by fastening means, such as rivets 5. Lagging 6, in the form of a sheet of'asbestos, lines the inner surface of the stationary side 1 of the casturned radially outward and then directly back upon themselves to form vertically disposed lips 7 that extend from bottom to top of the casing (as clearly illustrated in Fig. 2), the extreme edges of the side 1 being then bent inward and against the lagging 6, thus incasin'g the edge of the lagging and protecting it from injury. As already explained, a sheet of asbestos is found suitable for this lagging, and, as is well knownto thosewho are familar with the nature of this material, the same is more liable to injury at its edges than throughout its body portion. Therefore, if the edges are thoroughly protected it is reasonably safe against injury. The construction thus described thoroughly protects the edges of the lagging or asbestos'lining. This construction is clearly illustrated in Fig. 3. j
; asbestos,
within From Figs. 3 and 4 it will also be seen that the vertical edges of the movable front side 1 of the casing are bent outward and radially inward to form channels for coeperation with the lips 7 of the rear side of the casing. This movable side is provided with lagging 11, which may comprise a sheet of the same being thoroughly protected throughout its entire area by a liner plate 12, of substantially side 1 and having its vertical edges crimped about the ,corresponding'edges of the lagging. It is found preferable to thus protect the inner surface of the lagging of the cover for, besides this cover being movable, it may be entirely removed when occasion requires at which time it would be liable to injury because of the fact that the interior of the movable side is'so thoroughly exposed. As this description proceeds, it will be found that this is not true of the stationary side of the casing, for the laggin of this side of the casing is always protecte by the water circulating device. The upper end of the plate which comprises the body portion of the moyable side 1 is turned inward in a position to overlie the adjacent edge of the cover 2, when said side is in its normal position; a d'the lower end of the plate is bent, invyggii and then downward to repose flange .3 of the ring 3. Adjacent its lower end, the movable side of the casing has an opening over which a frame 16 is fitted and is attached by bolts 17 to the side 1", the frame having a door 18 hinged to it, said door being provided with transparent panels of mica or the like. I mmediately-above the door, the movable slde to the side 1, the plate having its upper end 45 isprovided with a handle 20' whereby the side may belraised. For the purpose of retaining the side elevated when desired I provide a stop shown in detail in Fig. 5 and comprising an angle plate 21, pivoted at 22 turned laterally at 23 so that it may form a' substantial abutment for the movable side "shell 25 is attached to the when turned into the path thereof, as shown in saidFig. 5. The bolts 17 which hold the frame 16 in 50 place, serve also to hold the lagging 11 and liner 12 to the side 1 anda rivet 24 performs the same. function, adjacent the upper end of the movable side. .I
As previously mentioned, and as shown in Figs. 2 and -zt, the upper end of the ring 3 is enlarged to form the flange 3*, and the lower end of the ring is reduced to provide a neck 3. The upper end of a semi-frusto-c0nica1 the shellisflared outward into a horizontal 5 plane to produce a flange 27 to which is attached'a member 28 that is preferably in j the form of a circular which is fiaredupwardly'and outwar 5 plate the ed e of fl as shown at 29, to produce apan.
the same shape as the.
body portion of the; ring 3, as by rivets 26, and at its 1 wer end front side of the distributing receptacle .30,-
is a carrier 34 which maybe swung from an inverted position above the distributing receptacle, through almost 180 to nearly a vertical position in front of-the distributing receptacle, an abutment 35 of the carrier engaging a stop 36 that is attached to'the front side of the member or pan 28, to hold the carrier in such position. In this position, the carrier mayreceive a dispensing receptacle 37, in the shape of a bottle having a spring closed valve 38 fitted within its mouth, and said dispensing receptacle, with the carrier, may be swung to inverted position to cause adjacent edge of,
the dispensing receptacle to assume-the pos'ition illustrated in Fig. 2, where the stem of its valve. 38 is shown as engaging the botthe shell 25, and said pipe is inclined down-' ward from such boss into theside of the shell through a notch 42, and thencehorizontally through a similar notch 43 (Fig.7)
that is formed in the opposite side of the shell. The pipe is attached to the shell by having perforated plates. 44 slipped lengthwise over the pipe before it is placed in position, and secured pipe '40 opposite the-distributing receptacle 30 is closed by a cap 46. A burner 47, of the same general type as that shown in the patent to Jeavons' No. 951,612, dated Mar. 8,
19.10, is attached to the plpe 40 central within the shell ,25, the same being communicatively 1 1 2 0 connected to the pipe throughthe elbow 48, in a' manner illustrated in the aforesaid to the adjacent portions of the shell, by bolts 45. The end of the.
J eavons patent. The outwardly flared lower end of the gallery within the neck 3 of the ring 3, leaving suflicient space between the adjacent portions of the neck and gallery to' allow the admission 49 of. the burner reposes of air in suflicient quantity to maintain- To the cover 2 ofthe casing is attached proper draft'conditions within the casing 1.
undue suction would be created within the casing by the natural draft of the flue plus the induced draft, and this would unbalance 69, shown in dot-and-dash lines, may be at-- the established draft conditions of the burner so as to impair its operation and reduce efiiciency of the apparatus by too rapidly drawing the products of combustion through the casingand thereby not permitting them to expend the full amount of their heat upon the water circulating device.
The water circulating device comprises an inlet manifold. and an outlet manifold 56 that are-connected by a series of circulating elements or coils 57 preferably formed of copper tubing. 5 The circulating device constitutes no part of my invention, but the form illustrated herein is found highly efficient and especially well adapted to my invention. The rear end of the inlet manifold 55 is provided with an enlargement 58, having flattened sides 59 that are ordinarily intended for the application of a: wrench for holding the manifold against twisting when applying a nut 60 to the threaded end 61 of the manifold, which projects through an aperture in the casing, the nut 60 acting with the enlargement 58 to squarely clamp the device in place. The designof my casing makes the use of a wrench for the purpose aforesaid extremely inconvenient if not impossible. To perform the function of the wrench, I employ a plate 62 that is secured, as by rivets 63', to the side 1 of the casing, the plate having an aperture which alines with the aperture of the casing through which the-end 61 of 1 the manifold extends. On each side of the enlargement 58, the plate is beaded at 64 for codperation with one of the flattened sides 59 of the aforesaid enlargement. When thus confined between the beads 64, the enlargement58 and manifold 55 are effectually held against turning. An ingress pipe 65, suggested by dot-and-dash lines in Fig. 4, may be attached to the in- 3r1fi3lly threadedend 61 of the inlet mani The outlet manifold 56 of the circulating device has an upwardly extending shank 66 that projects through an aperture 67 in the cover 2, the protruding end of theshank being threaded for the application of a nut 68, for the obvious purpose of clamping the manifold to the casing. The egress pipe tached to the outlet manifold. This manifold may be 'held against turning by a bracket that depends from the cover 2 and comprises a strap .70, formed somewhat in 70 the shapeof a V, and to the bottom of which is secured the central .portion of a strap 71, the ends of which are bent downward to embrace the sides of the manifold.
. In use, the water heater may be supported by the pipes 65 and 69, the entire apparatus being light enough in weight to permit of such support.
In Fig. 6 I have illustrated a modified form of ,my invention involvlng a burner of a difierent ty e than that shown in connection with the former embodiment, the. present burner being designated 75. This type of burner involves comminglin tubes 7 6 that are inclosed within a drum% commingling tubes and drum being, connected by rods 78. This style of burner is fully Serial disclosed in my copending application Number 49,405, filed Sept. 7, 1915. In
other respects, this form of my invention is practically the same as the one above described, he only essential differences besides the burner being the lengthening of the" semi-frusto-conical shell designated 25 -in this modification, in order to accommodate the commingling tubes and drum, and the omission of the door from the movable side of thecasing, such being unnecessary with the present style burner. It will be observed,
7, the 85 also, that a modified form of the ring attached to the lower end of the casing ls employed in connection with this form of my invention, the same being shown at 3 The unchanged parts of the apparatus are referred to by the same reference numerals as are applied to the corresponding parts of the other form of, my invention. 4
