HEATER.
Specification of Letters Patent. Patented 1W 1917.
Application filed July 26, 1915. Serial N 0. 42,083.
To all whom it may concern:
Be it known that I, STANISLAW J. LUKAS- ZEWSKI, a citizen of the United States, residing at Detroit, in the county of WVayne and State of Michigan, have invented a new and useful Heater, of which the following is a specification.
This invention relates to water heaters in which a volatile hydro-carbon constitutes the fuel, and its object is to provide a heater which, when mounted on the chassis of an automobile, will not be extinguished by the jarring of the vehicle when in motion or by the blast of air caused by the fan, which will be strong and compact, and which can be built at comparatively low cost.
This invention consists in a heating coil and a shell for the same, a novel bottom for the shell provided with a drainage connection, a novel burner within the shell having a drain for conducting the unvolatilized fuel, a trough for receiving this liquid fuel provided with .means for controlling the maximum height of the fuel therein, and a novel electric igniter for the fuel in the trough.
In the accompanying drawings, Figure l is a side elevation of this improved heater. Fig. 2 is a vertical central section on a plane parallel to that of Fig. 1. Fig. 3 is a plan of the head of the cylindrical shell. Fig. 4: is a section on the line l4c of Fig. 2, Fig. 5 is a plan of the burner. Fig. 6.is a plan of the igniter trough. Fig. 7 is a section on the line 7-7 of Fig. 6. Fig. 8 is a section on the line 8-8 of Fig. 6. Fig. 9 is a plan of the bottom of the shell. Fig. 10 is a section on the line 10-10 of Fig. 2. Fig. 11 is a section on the line 11-11 of Fig. 2. Fig. 12is a perspective of a baffle plate.
Similar reference characters refer to like parts throughout the several views.
, This heater may be used wherever water or other liquids are to be heated, but is especially adapted for heating the circulating liquid of automobile engines, as set forth in my prior Patent No. 1,007,710, dated November 7, 1911, and may be mounted in the position shown in the drawings of said patent. The present structure conslsts generally of a pair of heating coils and the shell therefor, a burner and its igniter, and the shell or casing for the burner.
The heating coils 1 and 2 preferably have the same number of turns, and their ends are welded, brazed or otherwise connected into the fittings 4t and 5, as shown in Figs. 2. and 41. The shell inclosing the coils is preferably formed of the two tubular meinbers 6 and 7, preferably of sheet steel, with the layer 8 of asbestos between them. A supply pipe 9 may screw into the fitting at, and a discharge pipe 10, preferably in the form of a nipple, may screw into the fitting 5. A nut 12 on the nipple 10 may hold the upper ends of the coils and the fitting 5 in position, while the elbow 13 may be screwed onto the nipple outside of the nut. A nut 14: on the pipe 9 may hold the lower ends of the coils and the fitting 4 in their proper position. A window 15 of any desired character may be provided at any convenient location.
As shown in Figs. 2 and 9, the bottom of the shell is generally in the form of a hemisphere '16 having a rectangular extension 17, the lower part of which is rounded. The bottom can be secured to the shell by means of screws 18 passing through the brackets 19 into the lugs 20'at the rim of the bottom, and also by the plate 22 secured to the shell by means of the screw 23 and provided with an inturned end 24 that engages the shoulder 25 on this bottom. The rim of the bottom is formed with. a groove 26 (Fig. 9) to receive the rounded end 27 of the valve body 28 of the burner, which end 27 is also mounted in a similar groove in the lower edge of the shell. By removing the screws 18 and 28, the bottom and the burner can be removed.
Fitting the upper end of the shell is a head 29 (Fig. 3) provided with downwardly extending lips 30 that fit against the interior wall of the shell, as shown in Fig. 2, a screw 32 extending through the shell into each lip. Holes 33 in the head permit the escape of products of combustion, and small pedestals 34: may be formed on the head to support cooking pots or pans a sufiicient distance from the head to prevent them stopping these holes 33. A baffle 35 may be secured to the lower face of the head to prevent too rapid flow of the hot gases, and a screen 36 of fine wire gauze may be used to prevent the passage of flame from the in-- terior of the shell.
A hood is normally mounted on the shell and consists of the body 38 having a lower flange 39 adapted to fit around the upper end of the shell, being provided with bayonet slots 40 to receive the heads of screws 32 and be thus secured to the shell. A cylindrical band 42 is supported by the skirting 4L3, mounted on the body, by means of ears 44.. A cap 45 has downwardly extending ears 46 that are attached to the band 42. This hood prevents the blast of air, caused by the fan just in the rear of the radiator, from passing into and down within the shell while permitting all products of combustion to escape.
The burner and its igniter are mounted within the shell and are constructed as follows. (See Fig. 2). A central tube has the lower end of its bore threaded to re ceive a nipple 51, which passes through a hole 52 in the bottom (Fig. 9) and receives a nut 53 by means of which the parts are held rigidly in position. The fuel supply pipe will be connected to this nipple. At the upper end of the nipple 51 is a ball 54 that constitutes a check valve and prevents surging of the liquid fuel in the burner. This tube 50 may be filled with filter gauze 55, if desired. At the upper end of this tube is the valve body 28 having a transverse'bore 56, in which the needle valve stem 57 is mounted, the tapering valve 58 at one end controls the flow of fuel from the passage 59. A bearing60- for the stem is fastened in the outer end of thevalve body, and a disk 62 having radial teeth maybe mounted on the outer end of this bearing. A handle 63 is secured to the stem 57 and provided with a resilient detent ca that engages the teeth on the disk 62 and thus prevents the stem from being turned through the jarring of the vehicle on which the heater is mounted.
A U-shaped mixing tube has parallel arms 65 and 66, one above the other, the lower being in alinement with the fuel discharge passage 59. The upper arm is fitted in an opening in the outer shell 67 of the burner proper, the upper portion of which is curved inwardly to form a burner ring 68 provided with slits 69 through which may pass the volatilized fuel and the air mixed therewith. A frusto-conical thimble 71 fits within this ring at its upper end and has a radial flange 72 that extends across the end of the 'shell 67 to complete the fuel chamber. A
few small holes 7 3 in this thimble 71 in line with the arm 65 of the mixing tube perm t a small amount of the fuel vapor to pass into the space around the stem 74. The U-tube,
of any desirable insulating material carries a connector 86 that joins to the spark plug by means of a wire 87 and to an engaging clamp 88 by means of the wire 89.
Mounted on the central raised portion of the trough is a perforated thimble 91, air passing up through the center of the trough into this thimble and then laterally outward. An annular plate 92, substantially U shaped in cross-section, confines the flame and also supplies it with air. A baffle plate 93 secured to the nozzle 94 by means of nuts 95 prevents the flame of the burning liquid in the trough from igniting the fuel that flows from the orifice 59. The bottom of the arm 66 of the mixing tube is so formed as to drain to the short pipe 96 that discharges into the trough 75.
Secured to the rectanguar extension 17 of the bottom and to the shell of the heater is an air chamber having sides 100, 101 and 102. Its cover 103 is mounted on the bracket 104 carried by the side 102 and on the shell, at such a distance above the air chamber that the flange or skirting 106 of this cover extends only a slight distance below the upper edge of the chamber. This cover is formed with perforations 105 to permit the escape of the excess of air which enters below the flange 106.
A baflie plate 107 having ears 109 may be connected to the cover, as shown in Figs. 2, 10 and 11. A plate 108 (Fig. 4) may be secured to extend between the walls 100 and 101, forming an air space between the air chamber and the shell of the heater. The walls 100 and 101 are shown formed with air holes 110. The operation of this device v is as follows:
The heater coils 1 and 2 are always full of the liquid to be heated. When the operation of the heater is desired, the handle 63 is turned back to slightly open the orifice 59. This will permit fuel to be forced from this orifice and flow across into the lower' arm 66 of the mixing tube, thence down the pipe 96 into the trough 75. The clamp 88 is then connected to a spark plug of the engine or to any other source of a proper current, which causes a spark to jump across from one of the points 79-84: to the other, which ignites the liquid in the trough. The flame from this liquid passes up around the tube 50 and heats the valve body 28 and soon volatilizes the liquid fuel. When volatilized, the fuel will mix with air in the mixing tube and pass into the ring 67 and out through the small holes 7 3 and the slits 69. The flame from the trough will ignite the fuel vapor, which will burn at these holes and slits, the flame at the holes 7 3 heating the stem 74C and thereby the body 28 after the flame in the trough 75 is extinguished because of lack of fuel.
Should the fuel in the trough 75 accumulate Cit too rapidly, it will flow off through the passage 80 into the trough 112 in the bottom 16, and may then be drained away by means of the pipe 113. As this heater is especially intended for use on automobiles which are usually kept for comparatively long periods of time in cold garages, it is often desirable to keep the heater in operation during the entire time the vehicle is thus stored. In order to prevent the flame of the heater from igniting any fumes of the hydrocarbon fuel that may be spilled on the floor, the screens 36 and 111 are provided and are of such fineness that a flame cannot pass through them, thus rendering a fire because of the use of this heater impossible.
It is often desirable to keep the heater in operation While the automobile is moving from place to place, especially when the vehic e is used for delivering goods or for soliciting orders. In such case, and on very windy days, strong blasts of air pass around the heater which would affect the flame unless proper battle plates were employed. By using a cover 103 having a flange 106 extending down below the upper edge of the air chamber, and by mounting a baflie plate 107 as shown, the flow of air into the chamber is greatly impeded.
As automobiles are constantly growing in favor for picnic purposes, the hood of this heater is made removable so that cooking utensils may be placed over the head 29, and food can then be heated while the engine is kept warm.
Many changes in the details and proportions of my construction may be made by those skilled in the art without departing from the spirit of my invention as set forth in the annexed claims.
