FREDERICK WILLIAM MAGEE, OF LONDON, ONTARIO, CANADA, ASSIGNOR OF ONE- HALF TO THOMAS WILLIAM BAKER, OF LONDON, ONTARIO, CANADA.

WATER HEATER.

T all whom it may concern:

Be it known that I, FREDERICK.WILLIAM -MAGEE, a subject of the King of Great Britain, and a resident of the city of London, in the county ofMiddleseX, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Water Heaters, of which the following i the specification. v

'My invention relates to improvements in water heaters and the object ofthe invention is to devise'a heater which is simple, cheap and efiicient and of a class particularly adapted for use in rural districts or in places where gas or electricity and'like sources of power are unavailable and at the same time to devise such a heater'as will prevent contamination of the water by smoke, smuts or noxious gases rising from the fire bed and further in which means are pro vided for preventing the warping ofthe heater parts liable to take place when subject to the radiation of heat from fuel such as coal, coke and the like and it consists'essentially of the following arrangement and construction of partsas hereinafter more particularly explained. Fig. 1 is a side elevation of my heater. Fig. 2 is a cross sectional view through Fig. 1. I

Fig. 3 is a plan sectional view online i 3, 2. i I I Fig. 4: is a fragmentary detail showing the mechanism for simultaneously operating a the smoke damper and hot air damper.

Fig. 5 is a fragmentary detail showing means for journalling the smoke damper within the smoke pipe.

In the drawings like characters of'reference indicate corresponding parts in each figure. 1

1 indicates the body of my water heater of the type disclosed by my United States Patent No. 1,328,682, dated January 20, 1920 which consists generally of an outer casing 1" carrying the condensing apparatus 2 and water distributing apparatus 3, such water distributing apparatus consisting of a dished receptacle 4 through which extend tubular members 5, the condenser 2 being provided with a central orifice 6 from which extends the outlet pipe 7, such outlet pipe extending through the condenser cover 8, of a deflector plate 9 having a central orifice 10 and a lower water distributing device 11 supported in a dished receptacle 12 having a central orifice 13. The condenser cover 8 is provided with a water supply pipe 14: and the receptacle 12 with a water discharge pipe 15.

, The outer casing 1 of the body 1 extends downward below the dished receptacle 12 so as to form a fire pot provided with a lining 16 of fire'clay or other suitable material. The upper edge of the fire clay 16 is spaced apart from the lower face of the receptacle flange 12* is turned over the upper edge of such flange as indicated at 19. 20 is a damper rod which extends through the front of the casing 1 and through the sleeve19 and is provided with a damper 21 operating within the sleeve 19 for a purpose which will hereinafter be set-forth.

The outer end of the damper rod 20 is provided with a T end. 22 is a grate frame resting upon a casing 2d forming the ash pit and 23 is a grate. 25 is an orifice formed in the fire pot provided with a surrounding flange 26. 27 is a smoke pipe damper rod journalled in the flange 26 preferably by forming a notch 28 therein at diametrically opposite points. 29 is a damper secured to thedamper rod 27 so as to operate within the flange 26 and open and close the passage through the orifice 25.

30 is a pipe extending from the flange 26. such pipe being turned vertically upward to form'the smoke pipe of the device and into which the pipe 7 leads. The lower end of the pipe 30 is also preferably notched at diametrically opposite points so as to extend around the smoke damper rod in opposition to the notches 28. 31 is a crank extendingfrom the outer end of the smoke damper rod 27. 32 is a pulley mounted in a bracket 33 carried by the heater. 34 is a doublewire as indicated at 35 and 36 extending around the pulley 32 and connected at- By this'means it will be seen thatwhen' the damper 21 is-turned torthe horizontal or closed position the damper29 Will be turned to the open position; and also when theq damper 21 is turned to the open position the damper 29 is turned .to-the closed position.-

IhWlll be seen from this description that after the smoke and gases have passed off from the fuel and; such. fuel has. become: incandescent there is: a clearpassage forheated' air'upward throughthesleevc 19 sodirected by the opening oftthe valve 21 and closing; ofthe. valve 29 and through the heaterby the orifice 10, tubes .5 and orifice.Gt to the,

outlet '1 leading to the smoke pipe 30.

When it is desired to start the heater an'd a fresh fire. is madeor freslrfuelyis put on&

\ the; fire bed the damper Ell is closed and the The smoke and noxious gases rising f-romwthefire thus pass directly outward throughthe orifice 25 into the smokepipe and are carried off. When all the noxious gasesdiave passed:

damper 29 openedv simultaneously.

oh? and the fire has ceased to produce smoke or gas the valve 21 is opened and the valve-- 29-closed, Thehot air thenpasses from the, lire pot directly upward through the heater:

and through the Water Which vis fed thereinto to heat it as fully set forth in mypriorl United- States patent hereinbefore referred to. j

The disc 177. forms means for. preventing the great heat generatedby i uel such, as.

coalfand coke detrimentally afiiecting the lower-end. of the heater body \vliich' vould otherwise be arped and thereby. have:

gases passing through-the.-outlet 25 directly fromf-the fire potlwithout'j-"passing; through the heater, pure heated air only passing up through the heater to heat the Water.

7 It Will thus beseen: that T have devised a heater which is particularly adapted for using fuel of the smoke emitting type such as' coal, coke, Wood, charcoal and the like, Which fuels not only produce smoke but produce fine sparks during the initial firing'of the fuel which fiy upwardc and if. permitted to mix with the water produce smuts which Willqdirty clothes and. be detrimentalin- 1.
