Appleman. fue@ July si,
rlhis invention relates to a novel and improved oil heater and has for its primary object to provide an oil heater which will insure complete vaporizingir of oil which is to be used in an oil burner. l
A further object is to provide a heater employing electric heatingl means.
Other objects will become apparent during the progress of the description.
In the drawings in which I have illustrated a preferred embodiment of my invention,
Fig. 1 is a longitudinal view partly in elevation and partly in section of my improved heater.
Fig. 2 is an end elevation thereof looking at the right end in Fig. 1. f
Fig. 3 is a section on the line 3 3 of Fig. 1, and
Fig. 4 is a section on the line 4 4 of 1. Referring to the drawings, 1 is a base of any suitable construction but which I have shown as screw threaded at 2 whereby it may be mounted in a suitable frame or support. Mounted on the base and secured thereto by any suitable means is a tube. 3 closed at its outer end 4. Within the tube 3 is a spiral 6 which may be formed in any manner but which I have shown as formed of a coil of wire. This spiral fits immediately within the wall of the tube 3.
Supported on the base 1 in any suitable manner as by beincf threaded thereto is a second tube 7 connecting with a passageway 8 in said base. Surrounding the tube 7 is a sleeve 9 and between the walls of the tube and sleeve is placed suitable insulating;` and heat conductingr material 10 havingg` a plurality of bores 11 therein. Placed within these bores are suitable resistance elements 12 which are 4 thus insulated from the tube 7 and from the sleeve 9 as well as from one another. These resistance elements are preferably connected in series as shown in Fia. 4 at 13. The resistance elements are provided at the base of the vaporizer with suitable terminals 14 for connection to any suitable source of electricity.
The base 1 is further provided with a plurality of inlets 15 communicating with an enlarged openingr 16 for the reception of a suitable connection to a source of fuel` such as oil.
In operation fuel is admitted through the inlets 15 into the path formed by the spiral 6.,
and passes around the spiral until it reaches the end 4 of the tube. During this passage of the fuel the resistance elements 12 are 1924. Serial No. 729.381.
heated and the result is that the fuel is substantially completely vaporized. The fuel then flows bach through the inner tube 7 and out of the passageway 8 which may be connected to a suitable conduit leading to a burner. By providing` this circuitous path for the fuel I insure that ample opportunity is given for it to become vaporized and heated before passing' to the burner. The plurality of inlets 15 separates the fuel to some extent and spreads it out into a sheet, in which form it enters the spiral path formed by the wire or the like 6, and therefore presents a .larne surface to be heated. The result is that the oil or other fuel is well vaporized by the time it reaches the end of the spiral and whatever oil is not vaporized becomes vaporized on the return throupjh the inner tube 7. Furthermore. during` this passage through the tube 7 the entire gas is further heated before passing to the burner. y
Theemployment of electrical heating' elements is very desirable, not only because of cleanliness but because of the ease with which the heat may be regulated, for example, by rheostats and automatic switches. For eX- ample, I employ this heater with a thermostat control, as described in my co-pending application, Serial No. 7 35,511, filed September 2, 1924. Moreover, it is a simple matter to remove and replace any resistance element as it becomes worn out.
From the above description it will be seen that I have provided a heater which is etilcient in operation, which is readily. controlled to vary the amount of heat, and which will insure proper vaporization and heatingof the fuel. y
I am aware that changes in the form, construction and arrangement of parts may be made without departing` from the spirit and without sacrificing` the advantages of the invention and I reserve the right to make all such changes as fairly fall within the scope of the following` claims.
I claim Prx'rlatrr OFFICE.
1. An oil heater comprisinga vaporizine 10 ing communication With the space between the tube und sleeve, u spiral between said tube enel sleevefor causing Said fuel to take a eireuitous path through the length of Said sleeve, L pipe in seid sleeve, e vapor outlet in said plug` and communicating with seid pipe, and
f wheatingelementbetween seid pipe and said sleeve, said fuel being, in continuous Contact With e heated Surface through its entire travel Within the tube.
