am By MW-"22 United States Patent ELECTRIC STEAM BOILER Armin C. Beiermann, Wayne, Nebr. Application December 31, 1956, Serial No. 631,833 1 Claim. (Cl. 219-38) This invention relies on the provision of a novel electric steam boiler for use by bee keepers in the operation of extracting honey.
The primary object of the present invention resides in the provision of an electric steam boiler for use in extracting honey in lieu of conventional gasoline appliance conventionally used for producing steam.
A further object of the invention resides in the provision of means for elimination of the dangers conventionally present in operations of extracting honey when using gasoline appliance for producing steam, such as the fire hazards produced by the fumes, the lack of sanitation and chance of adulteration of the honey by the gasoline fumes, smoke and other exhaust such as carbon monoxide produced during the burning of the gasoline and the necessity for maintaining pressure in the tank at regular intervals by pumping of air into the tank.
Still further objects and features of this invention reside in the provision of an electric steam boiler that is convenient in operation, simple in construction and manufacture, and relatively inexpensive to use thereby permitting wide use and distribution.
These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by this electric steam boiler, a preferred embodiment of which has been illustrated in the accompanying drawings, by way of example only, wherein:
Figure 1 is a top plan view of the steam boiler comprising the present invention;
Figure 2 is a vertical sectional view as taken along the plane of line 22 of Figure 1; and
Figure 3 is a horizontal sectional view of the steam boiler taken along the plane of line 3-3 in Figure 2.
With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, reference numeral generally designates the electric steam boiler comprising the present invention which includes a receptacle 12 having a covering of insulative material 14 and provided with an outer casing 16. Secured to the outer casing are suitable legs, such as the tripod arrangement including legs 18, and 22. Secured to each of the legs are threaded adjusting members 24, 26, and 28 which serve to enable the boiler to be held in a substantially vertical position even if the ground on which it is standing is not precisely level.
The receptacle 12 includes a top with insulation as at 32. Depending from the top 32 is a magnesium rod 34 for inhibiting corrosion of the material from which the tank 12 is constructed.
The tank 12 is provided with a water level indicating which is provided tube 36 connected to an outlet pipe 38 and a drain pipe 40 and extending therebetween. A drain valve 42 is also provided.
Secured in the bottom 44 of the receptacle 12 are suitable immersion heating elements 46 and 48. These immersion heating elements are connected through conductors 50 to a relay 52 mounted on a yoke or support 54 secured to the top 32. The relay 52 controls flow of electrical current from a source of power to which it is connected through a conductor 56 to the immersion heating elements 46 and 43. The relay 52 in turn is controlled by a pressure control switch 60 connected through a conduit 62 to the interior of the receptacle 12. It is noted that the conduit 62 is provided with a bend or turn as at 64 for preventing moisture from entering the pressure control switch 60.
The top 32 is provided with conduits therethrough for connection to a pressure gauge as at and other conduits as at 72 and 74 for connection to capping melters as well as a conduit 76 for connection to a steam knife.
In use, the pressure switch is adjusted to cut the current to the heating elements at different amounts of steam pressure. As the pressure increases above the pre-set pressure, the pressure control switch will function to cause the relay 52 to open a circuit between the source of electrical power and the heating elements. However, as soon as the pressure decreases below a certain limit, the relay will again be actuated to close the electric circuits to the heating elements.
The top 30 is detachable from the rest of the receptacle 12 and suitable latching means 80 is provided for holding the top 30 in place. Suitable gaskets are provided as at 82 for assuring that the receptacle 12 is steam tight.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
What is claimed as new is as follows:
A boiler for use in extracting honey comprising a steam tight receptacle, at least one electric immersion heating element secured to the base of said receptacle and extending into said receptacle, said receptacle having a removable top, a source of electrical power, a support carried by said top, a pressure control switch mounted on said support, a conduit connected to said pressure control switch and extending through said top to communicate said pressure control switch with the interior of said receptacle, a relay on said support controlling flow of electrical power from said source to said heating element, said relay being connected to said pressure control switch and being controlled thereby, and a plurality of outlet conduits secured to said top and communicating with the interior of said receptacle, said top having a corrosion inhibiting magnesium rod secured thereto and depending down into said receptacle.
