Gaschnitz, liinnson', Alberta, Canada Application May 3, 1943,, Serial No. 485,522 in Canada May'26', 1942 G-Glai'ms. 1

My" invention relates to a heater for the circulating' water within the jacket of automobile and truck engines, an object thereof being to provide a device of the character described. by means of. which the water may be kept hot and the enginewarm in frigid'we'ather by'n'ovel means and (with respect'to the first andm'ore important embodiment) without the. employment of electrical power.

A further object of my invention is to provide a device of the character described which can be readily put intooperation' by the driver of the auto or truck from his position in the. cab thereof.

A further object of my'i'nvention' is to provide a circulating" water heater in the form. of a small, horizontal, water tube boiler to which is connected, as a unit, a blow torch specially designed for use with the said boiler and including selfigniting mechanism integral with the blow torch.

A further object of my invention is to provide a device having the foregoing objects which is eminently simple to operate, inexpensive to manufacture and which cannot readily become out of order.

With the above more important objects in View and such other minor objects as may appear as the specification proceeds, my invention consists essentially in the arrangement and construction of parts all as hereinafter more particularly described, reference being had to the accompanying drawings, in which-- Figure 1 is a sectional elevation of my device in situ.

Figure 2 is an enlarged sectional elevation of my self -igniting mechanism.

Figure 3 is a section on the line 33 of Figure 2.

Figure 4 is a side elevation of my device as a whole and illustrating the same as positioned in an automobile.

Figure 5 is a sectional elevation of an alternative, electrically heated embodiment of my invention.

Figure 6 is a view similar to Figure 4 of the embodiment of my invention illustrated in Figure 5.

In the drawings like characters of reference indicate corresponding parts in the different figures.

My invention will preferably; though not necessarily', extend upon either side of the bulkhead l of an automobile 2 or a truck, an aperture 3 being formed in the bulkhead for this purpose. It isto be understood that my water tube boiler 4 will be positioned upon the engine side 5. of the bulkhead while the blow torch enumerated 6 as. a whole, will be positioned upon the cab side I: of the. bulkhead convenient to the driver.

My water. tube boiler 4 comprises the. surrounding jacket 8 and the inner jacket 9 interconnected"v by the passages Ill, although at this point, I desire to state. that the. boiler maybe of: any configuration. as to the arrangement of the: tubes therein. However, the foregoing arrangement permits of the. distribution of a flame through. the center tube ii and the annular tube 5% as. I have indicated by' the group of arrows 43, the spent heat from the flame being, discharged. through. the. exhaust M. The boiler which. I have described. will be connected up to the conventional water jacket oi an associated engine 15 at any two convenient points I5! and I5", preferably by means of. flexible hose which will. connect with the water intake and discharge nipples l6 and IT respectively.

The boiler is securedto the bulkhead by means of the surrounding flange l8 which encircles the aperture 3, a sleeve portion i9 projecting through. the aperture 3. into the cab below and behind. the dashboard 28 to this sleeve, my blow torch 61 is connected.

The blow torchv consists of a fuel tank 2.! which may also. be. secured to the bulkhead. as at 22 if. desired, a conventional pump assembly 23 being associated with the fuel tank. Positioned above the fuel. tank is a fire nozzle 24 directed towards the. tubes of. the boiler, the jet 25 associated with the nozzle, drawing fuel from the tank H by means of the supply pipe 26.

The fire nozzle is surrounded by the housing 2"! sufficiently provided with. air holes 23' to feed the flame from the nozzle 24. The housing is secured to and around thesleeve l9 whichsockets into the annular projecting flange 29 of the housing.

Below the nozzle 2.41 I'provide a fuel pan 3!! into which a certain amount of fuel will drip when the jet 25 is opened and pressure has been built up in the tank I! by the pump 23. Associated with the pan as best illustrated in the accompanying Figure 2 is a wick Si and a surrounding wick tube 32 the upper end of which projects into the pan and is normally covered by the extinguisher 33.

The extinguisher is mounted for rotation on the stub shaft 34 (see Figure 3) which is journalled in the pair of upstanding brackets 35 secured to the pan 3%. Within the interior of the extinguisher I locate a flint-wheel 36, while against one wall of the extinguisher is mounted a small pinion 31, the extinguisher, flint-wheel and pinion rotating as a, unit.

In mesh with the pinion 3'! is a rack 38 connected to the push rod and finger disc 39, the rod extendin through the projecting sleeve it on the pan, which sleeve contains a small coil spring 4!.

An upwardly spring pressed flint 42 bears against the fiint-wheel 36 and is contained within the receptacle &3 and from the foregoing, it will clearly be recognized that upon the impression of linear movement against the push rod in the direction of the arrow 53 (Figure 2), the pinions, flint-wheel and snuffer will be rotated in a clockwise direction as indicated by the numeral 44 so that the upper end of the wick is uncovered, while, at the same time, a spark is thrown against it.

The ignited wick sets fire to the fuel within the pan 3ii, which in turn ignites the fuel proseeding from the jet 25 under pressure, and thus the blow torch is ignited. The contents of the pan are soon used up and a clean, hot flame is soon playing on the surfaces of the fire tubes I! and i2.

The alternative, electrically heated embodiment of my heater as illustrated in the accompanying Figures 5 and 6, may be located upon either side of the bulkhead I although I have shown it connected upon the cab side i. For this embodiment, I prefer to employ a vertical arrangement of tubes, although I do not wish to be restricted to a vertical arrangement.

The vertical arrangement which I have shown in the accompanying Figure 5 is similar to the horizontal arrangement of Figure 1 for which reason, the same numerology has been employed.

Intake and return water nipples 45 and 45 respectively project through the bulkhead to be connected via a hose or some other suitable con nection to the water jacket of the associated engine.

Beneath the arrangement of tubes, is a heating chamber 51 containing an electrical element or resistance 48. The heat from the resistance rises through the tubes H and i2, being allowed to escape through the exhaust port 49, and thus, it will be seen that I have provided a simple and effective electrical embodiment which can readily be connected and disconnected at the socket Ell by the operator of the automobile or truck.

In conclusion, I would particularly point out that while my herein described device obviously operates in a highly emcient manner to maintain the temperature of water in an associated engine water jacket, the same is primarily designed, and conspicuously useful for heating the water in subzero weather, and after an automobile, for instance, has been exposed to such weather so that it is of the same temperature. It will be understood that in winter, the engine jacket will contain a mixture of water and anti-freeze which, as is well known, does not freeze solid, but only congeals into a semi-fluid mass at the lowest temperatures likely to be encountered.

Since many modifications can be made in the invention herein described and since the accompanying drawings have been prepared only to illustrate the relative arrangement and interaction of parts and, not with regard to accuracy of dimensions for manufacturing purposes which in view of this disclosure I consider to entail merely mechanical skill together with the skill of the mechanical draftsman, and since many apparently widely different embodiments of this invention may be made within the scope of the accompanying claim without departing from the spirit and scope of the same it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense and I desire only such limitations placed thereon as justice dictates.
