STEAM OR HOT-WATER HEATING DEVICE.

SPECIFIOATION'fQrming part of Letters Patent No. 641,186, dated January 9, 1900.

Application filed April 26, 1899- To (all whmn it may concern:

Be it known that 1, WILLIAM F. BURNS, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Steam or Hot-water Heating Devices, of which the following is a specification.

This invention relates to improvements in steam or hot-water heating devices; and it is carried out as follows, reference being had to the accompanying drawings, wherein Figure 1 represents a top plan View of the invention. Fig. 2 represents a longitudinal section on the line 22, shown in Fig. 1. Fig. 3 represents a rear view showing the smokehood removed and the deflector swung downward in position for closing the ends of the lower row of tubes; and Fig. 4 represents a horizontal section on the line 4 4, shown in Fig. 2.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

A represents the vertical inclosing shell of the furnace, provided with the internal fire: brick lining B, grate O, fire-pot D, ash-pit E, and doors cl 6, leading, respectively, to the said fire-pot and ash-pit, as is common in de vices of this kind. On top of the vertical furnace is arranged the vertical steam-boiler or water-heater F, provided with a series of horizontally-arranged tubes f f and f f, going from end to end of said boiler or waterheater, as shown in Figs. 2, 3, and 4.

G is the steam or hot-water delivery pipe, leading from the upper portion of the boiler F, and 1-1 is the return-pipe, as is common in steam or water heating devices. At the rear end of the boiler or heater F is pivoted at i 1 the spindle I of the deflector I, as shown in Figs. 2, 3, and 4. The said deflector is normally held in the position shown in Figs. 2 and 4. -To one end of said spindle I is preferably secured a handle or lever I, by means of which the position of the said deflector may be adjusted, for a purpose as will hereinafter be described. The lever I may be secured temporarily in any of its adjusted positions by means of any suitable or well-known fastening device.

To the forward end of the boiler F is hinged Serial No. 714,508. (No model.)

at it the casing K, which when in its normal position is held in the position shown in Figs. 1, 2, and 4. Between said casing and the forward end of the boiler is a smoke-passage L. (Shown in Figs. 2 and 4.) To the rear end of the boiler is secured the casing M, the upper portion of which is provided with a smokestack M, leading to the chimney in the building. Between said casing M and the rear end of the boiler is a smoke-passage N, which is connected to the rear upper portion of the fire-pot D, as represented in Fig. 2.

During the ordinary use of the furnace and boiler the casing K and deflector I are held in their normal positions, as represented in Fig. 2, causing the gaseous heat products from the furnace to pass into smoke-passage N and through the lower tubes f f into smokechamber L and thence through the upper tubes f f and smoke-stack h in the direction of the arrows, as shown in said Fig. 2, and by this arrangement the water in the boiler is heated partially by direct radiation from the furnace onto the bottom of the boiler and additionally by the heated products from the furnace being conducted through the tubes ff and smoke-chamber or return-passage L, thus obtaining a very large heating-surface, and in this manner I obtain the most efleotive and economical results.

If at any time during the use of the furnace and boiler it should be desirable to clean the boiler-tubes, this can be done without raking the fire simply by swinging the deflector I downward, as shown in Fig. 3, causing the heated products from the furnace to pass directly out through the smoke-stack M. The casing K is then swung upward to the posi tion shown in dotted lines in Fig. 2, and as the upper tubes f are then exposed a suitable cleaning-tool or tube-cleaner may be introduced into such upper tubes for the purpose of cleaning them.

If it is desired to clean the lower tubes ff, I simply swing the deflector upward into a vertical position, so as to enable a suitable tube-cleaning tool to be pushed through such tubes. After the tubes have thus been position.

The invention is very simple in construction, is easily operated, is a great f uel-saver, and may be equally well used for steam or hot-water heating systems, as may be desired.

In the drawings 1 have represented the boiler F as designed for hot-water heating systems; but if desired for steam-heating purposes I would simply modify the construction of the boiler by making it sufficiently high removable casing 70 arranged at one end of the boiler opposite the ends of the tubes, a casing M arranged at the opposite end of the boiler in rear of the other ends of the tubes and connected with the fire-pot and the smokeiiue, and a hinged deflector disposed within the casing M between the rear ends of the upper and lower series of tubes and operating when turned horizontally to conduct the products from the furnace successively through the lower and upper series of tubes, and when turned downward to close the lower tubes and conduct the furnace products directly to the smoke-flue, substantially as described and for the purpose specified.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- IIGSSQS.
