Patented March 13, 1906.
Application filed February 16, 1905. Serial No. 245,861.
description thereof, reference being had to" the accompanying drawings of this specification.
' One of'the objects of my invention is. to
which form part provide a water-heating attachment for furnaces which is simple in construction, efficient in o 'eration, and of reat durability.
In'the rawings I have s own, in Figure 1, the application of a device embodying my invention in a diagrammatically-illustrated furnace. j iglisasection offline 2 2 of Fig.
- 3, and Fig. 3 is an elevation of the bottom of my device.
Throughout the drawings like characters of reference refer always to like parts.
The water-heater, or, as I term it in the trade, the heat-economizer, comprises a shell 5, preferably of circular form in plan and vertically relatively thin, so as to form a relatively short cylinder, said shell preferably providing a fiat top wall 6, a cylindrical side wall 7, a cylindrical inner wall 8, and a bot-- tom wall 9, of configuration to be more specifically described, forming an annular chamber. The bottom wall9 is interrupted by parallel transverse ribs 11, separated by suitable spaces 12, and eac cated at 10, opening into and constituting a continuation of the chamber 10. Preferably the walls 6, 7, 8, and 9 are walls of substantially the same thickness, although they may be varied in thickness, if required. From the inner circular wall 8 projects ribs 13 13, preferably solid and of tapering form, all converging toward the vertical aXis of the casing, said ribs being separated at suitable distffiaces to leave s aces 14 therebetween and all sto ping, pref rably, at equal distances'from t e axis of the casing to leave a central free opening 15. Inlet and outlet apertures 16 and 17,
ollewrib'fas indipreferably screw threaded to receive suitable piping, are provided at opposite sides of the shell, the inlet-opening 16' being preferably near the bottom thereof and the outletopening 17 being near the top.
In use the device is suspended in' the fur-' nace by the inlet and outlet pipes 18 and 19, threaded into the apertures 16 and 17 and finding bearing in apertures a a in the side side walls a a of the furnace A, the economizerbeing located at a suitable point above the furnace-grate .B. It will be apparent that the heat of the fire upon the grate B impinges upon the larger lower surface of the ribs 11 and rapidly heats the water therein and that the gases of combustion escape through the central opening 15 andthe spaces 14, communicating heat to the-large exposedsurfaoes of the vertical ribs 13 and through said ribs to the water within the chamber 10. By this arrangement I provide a very simple and efficient water heater which may be readily attached to furnaces and which I find in practice does not lower the eflioiency of the furnace for its usual work to any appreciable degree. Obvidusly the piping 18 19 may be run to any suitable source of the water-suppl and, if desired, .to any suitable receptacle or the heated water. These parts, however, are not shown. A
Having thus described my invention, what 'I claim, and desire to secure by Letters Patent of the United States, is
As an article of manufacture, a waterheater for furnaces comprising the annular shell of heat-conductive material provided with the hollow de ending ribs 11 on its under side and with tfie converging solid ribs 18 surrounding its central opening, substantially as described.
In testimony that I claim the foregoing as my own I aflix my signature in presence of two witnesses.
