HEATER I Filed 001;. 6. 1938 Hillard J- Sand: lwvzunuR Patented Apr. 23, 1940 I UNITED STATES PATENT OFFICE" HEATER Hillard J. Sands, Cleveland, Ohio, assignor to Garry Sands, Cleveland, Ohio Application October 6, 1938, Serial No. 233,692

14 Claims. 122-250) This invention relates to heaters, more particularly to hot water heaters, and has for an object the provision of a new and improved heater of this character, and wherein parts thereof are readily assembled or disassembled, as conditions may require, and when assembled the parts are securely fastened together.

Other and further objects of the invention will be apparent to those skilled in the art from the following description of the drawing in which:

Figure 1 is a broken front elevational view, partly in section, of the heater construction,

Figure 2 is an enlarged broken, fragmentary, vertical sectional View, corresponding substantially to the line 2--2 of Figure 1,

Figure 3 is an exploded perspective View of the heater construction, portions of the same being broken away, illustrating the manner in which the parts of the heater may be assembled, while Figure 4 is a reduced bottom plan View of the heater base.

As shown in the drawing, the invention com-- prises an elongated outer casing Ill, preferably of sheet-metal, and preferably octagonal in crosssection, at the lower end of which there is provided base means II, carrying an upstanding frame I2, extending along a vertical portion of the casing I0.

The base means I I preferably are formed from sheet-metal, having an outer curved depending flange I3, substantially octagonal in plan, merging with an upstanding corrugation or embossment Id, at its inner side terminating in a short flange I5, the embossment I4 at its outer side being octagonal in plan, to conform to the shape of the casing III, the lower edges of the latter being adapted to lie snugly against the outer octagonal surface of the embossment I4 when in position on the base means II, and to rest upon the flange I3, while the inner surface of the embossment I4, is circular in plan to conform to the contour of a circular inner casing hereinafter mentioned.

Seven sides of the octagonally shaped base means are preferably identically formed, but an eighth side I6 is differently formed. The eighth side I6 of the base means I I is formed to provide a depressed platform I! the ends of which are outer walls of the embossments l8 and I9 merg-- v ing with the adjacent portions of the flange IS,

the embossment I4 of course being mit ed f om the platform area,

The depressed platform IT is provided for the reception of the lower end of the frame I2, the frame I2 having an angular longitudinally extending flange 20 thereon, shaped to fit within the embossments I8 and I9 and to rest flat upon the platform H, the flange 20 preferably being spot-welded, or otherwise secured, to the platform IT, to fixedly secure the frame l2 to the base means II. Both the flange 20 and platform H are provided with cut-outs indicated at 2|, for a. purpose presently to appear, the flange I5, heretofore mentioned defining a circular opening in the base means, which communicates with the cut-outs 2|. The frame I2 also comprises at the inner opposite ends of the flange 20, spaced vertically extending sections 22, merging at their upper ends with an arched shaped connecting section 23, one side 24 of the casing Ill being cut out to accommodate the frame I2. The upstanding portions 22, have inclined outer flanges 25 conforming to the contour of the adjacent sides 26 of the casing I0 and overlie the adjacent edges of the cut-out in the casing Ill, and the arched section 23 is provided with a vertically extending flange 21 overlying the adjacent part of the side 24 of the casing I0, which defines the casing cut-out, a pair of spaced ears 28 being formed adjacent to the junctions of the upright and arch sections 22 and 23, and through which fasteners, as screws, may be extended to secure the frame to-the casing I0. integrally formed with the vertical sections 22 and with the arched section 23 are inwardly directed webs 29, adjacent the arched section 23 and the upper ends of the vertical sections 22, merging into a vertically extended web 38, having an arcuate opening 3l therein, bounded by an integrally formed inwardly directed semi-circular flange 32, the lower ends of the upright sections 22, being outwardly offset, and merging with the web3ll by offset portions 34, all defining a socket-like depression for the reception of coil securing means hereinafter mentioned.

-A cylindrical inner casing-35 is disposed within the outer casing Ill, and spaced therefrom, the inner casing 35 having a cut-out 36, and an outwardly directed flange 31 surrounding the cut-out, the flange 31 fitting over the outer surface of the web 29 of the frame I2, while the lower edges of the inner casing 35 bear snugly against the inner circular surface of the embossment I4, and rest upon the flange I5, suitable insulating material being arranged between the outer casing I0 and inner casin 35in, a manner well understood in the art.

A top member 38 is provided having a depending flange, octagonal in plan, which fits over the top edges of the cas ng II), the top member 38, the base means H, and the interposed casings l0 and being clamped together by tie rods All. The top member 38 is provided with an outlet 4| for the products of combustion, and is also provided with an opening through which the threaded end of the water coil 42 is projected, the latter being fastened by a nut 53 to the top member 38, the nut 43 not being intended to support the relatively heavy coil 42, but merely to position the same, the opposite end of the coil 62 being provided with a threaded fitting positioned to extend through the semi-circular opening 3|, the fitting Al i having'a shoulder 5, adapted to butt against the inner edge of the flange 32, and the threaded portion adapted to receive a nut 46, which lies against the depressed web 30, above the ofiset portions 34, and when the nut M is drawn up, the Weight of the coil ,42 is suported partially by the frame I2 as will be understood.

The major portion of the weight of the coil, however, is supported by the bottom supporting means ti. The bottom means 47 preferably is circular in outline, dished somewhat to provide a central portion {58, having air vents 49 therein, and a central opening for the passage of a gas pipe 56, carrying a burner 55!, inner and outer nuts 52 preferably being employed to clamp the gas pipe in position.

outwardly of the central portion 48 the bottom means 41 has a horiozntally extending fiange 52, adapted to be detaohably secured to the under surface of the base means H by screw bolts 53 taking through suitable apertures therein and adapted to engage suitable threaded bosses in the base means H, as indicated at 5 1, the bottom means 47 being of suificient sizeto completelyclose the circular opening in the base means defined by the flange l5, thereby providing for the interception and retention of condensation moisture from the coil $22. It should also be noted that by reason of the upstanding nature of the embossment l4, and the manner in which the casings l0 and 35 are assembled therewith, condensation never enters between the casings, and hence the insulation therebetween is maintained in dry con: dition at all times.

Rigidly afiixed to the flange 52 of the bottom means 47 is an upstandi g support 55, preferably corrugated, as at 56, to increase its strength, and at its upper end provided with spaced supporting surfaces 51, arranged generally in semi-circular formation, and of a character to engage the under surface of the shOlllder when in position, to provide the principal support for the relatively heavy coil 42, the support 55 being positioned to extend between the side sections 22, and rear- Wardly thereof, into supporting engagement with the fitting M when operative position.

Once assembled, as described, the relatively heavy coil 32 is supported directly from the base means ll, providing a verystron g and attractive construction. If the coil (l2 should burn out, or become clogged with foreign matter, the coil may be removed merely by loosening the nut G3, loosening the nut 46, removing the screw bolts 53, and dropping the bottom means 41, and coil [22, from the lower ends of the casings l0 and 35, the support 55 and fitting M clearing through the cut-out 2|, and the circular opening defined by the fiange l5 which communicates therewith, all Without disturbing the fixed structural parts of the heater, and, of course, when the coil 42 has been cleaned, or a substitute provided, the parts may be re-assembled in the manner already described, merely by replacing the same, tightening up the nuts 53 and 45, and replacing the holding screws 53.

It will be apparent to those skilled in the art that I have accomplished at least the principal object of my invention, and it also will be apparent to those skilled in the art that the embodiment herein described may be variously changed and modified, without departing from the spirit of the invention, and that the invention is capable of uses and has advantages not herein specifically described; hence it will be appreciated that the herein disclosed embodiment is illustrative only, and that my invention is not limited thereto.
