K. K. SIKES HEATER AND STERILIZER Filed April 50, 1928 INVENTOR /x .S/(e5 Www, Arro'RNEY /fenne' Patented Nov. 12, 1929 PATENT OFFICE KENNETH K. SIKES, OF TOLT, WASHINGTON HEATER AND STERILIZER Application led April 30,

This invention relates to a device particularly suitable for the use of farmers and dairymen in providing hot water in barns, or other outbuildings, and also for sterilizingmill; utensils, or the like, through the actions of water and steam.

Heretofore devices have been produced for sterilizing such utensils, but they have been more or less complicated in construction, and,

in View of their cost to manufacture, have been offered at prices which in many in stances proved prohibitive te those who had use for same. None of said devices, so far as known to me, are designed or adapted to also perform the double duty of furnishing hot water for use.

The objects of my invention, generally stated, are, to provide a heater and sterilizer which performs said functions and makes 2o conveniently availablemeans for sterilizing such utensils and supplying yhot water in the environment mentioned; and, to afford such a device which, while utilizing an immersion type of water heater, nevertheless, has few and simple parts, thereby permitting it to be produced and sold at a relatively low cost.

Other objects may appear as the description of the invention progresses.

In the accompanying drawing- Figure l is a view, in elevation, of the device;

Fig. 2, a vertical section of the same; and, Fig. 3, a cross section, drawn on the line 3 3, of Fig. l.

Referring more particularly to the draw ing, the device consists of a cylindrical container, generally denoted as 1, formed of a lurality of wooden staves 2, secured in place by metallic bands 3, and provided with a bottom portion 4, also of wood.

A cover, having a circular and wooden body portion 5, reenforced by a wooden circular portion 6, reduced in diameter, is provided on its lower surface With a covering of i5 sheet copper 7. Said surface is of a form complementary to the open top of the container, the portion 6 obviously holding the cover against lateral displacement, and said copper affording a lining which strengthens the cover against warping and is non-rusting 1928. 'Serial No. 273,896.

when in Contact withy water or steam. handle for the cover, secured to said body portion, is designated as 8.

A false wooden bottom, consisting of a plurality of cleats 9, supported by a pair of transversely extending cleats l0, secured thereto, is disposed within the container, in spaced relation with the adjacent vertically extending surface and elevated from the bottom thereof, as indicated in Fig. 2, the same being designed to support utensils to be treated.

For the purpose of supplying heat to the device I utilize an immersion type of electric heater, the heat-dispensing member thereof, f operatively disposed in the container and below the false bottom, and the plug connected with saidv member 'and socketed in the container, being denoted as ll and l2 respectively. The wires i3y connected with the plug 'f indicate, as is evident, the usual means through which electrical communication is established with the heating member from the source of supply. The electric heater thus employed is designed to be a conventional one of the variety to which it belongs, and its construction consequently is no part of my invention. 14 denotes a faucet, through which water may be drawn from they container.

A cementitious coat of heat-insulating material 15 is applied to the outside of the container, in a plastic condition, and smoothed down, as is more particularly shown in Fig. 2. 'I'he composition, thus applied, conserves the heat generated by the heater, and will effect a considerable saving in the electrical energy required to operate it in connection with the device. It also permits the staves and metallic bands to be covered, thereby imparting to the container a more pleasing appearance. I prefer to use a composition which includes asbestos as one of its ingredients, and, as will be obvious to those skilled in the art, any one of a number of heat-insulating compositions is suitable for the purposes intended.

The desired quantity of water having been placed in the container and heated to the required temperature, through the instrumen talities shown and described, liot Water, as is obvious, may be drawn from the faucet for use and utensils placed on the false bottom, Where they Will be subjected to the cleansing and Sterilizing` actions of Water and steam.

In the present embodiment of the invention I have disclosed a structure which, in its interior aspect, presents a construction which is practically all ot Wood, thereby permitting the utensils, While being treated, to come in contact only with parte thereof .vlii'chV are non-rusting and non-corrosive, and enabling it to be readily cleaned and kept in a sanitary condition.

I claim l. A Water heater and sterilizer, comprising a Wooden container, a cementitious covering of heat-insulating material around the container, a cover for the container, a false Wooden bottom, having openings t0 permit the circulation of Water and steam therethrough, a hot-Water faucet, and an immersion type of electric beater operatively disposed Within the container and below the false bottom.

2. A device for supplying hot Water and sterilizing dairy utensils by steam; comprising a container, a heat-insulating medium eX- tending exteriorly of the container, a cover for the container, an elevated support disposed in the bottom oi the container adapted to permit the circulation of Water and steam therearound, a hot-Water faucet and an im'- mersion type or" electric heater operatively disposed Within the container.
