Description
R. R. FISHER BOTTLE HEATER Feb. 27, 1945.
Filed June 12, 1943 INVENTOR. Ffsber Re R.
Patented Feb. 27, 1945 UNITED STATES PATENT OFFICE 3 Claims.
This application relates to a bottle heater.
In the present war economy, material which has generall been used for bottle 'warmers is not available. The present invention contemplates a bottle warmer for nursery use which is composed almost entirely of non-critical materials.
It is a further object of the present invention to provide an electrically heated bottle warmer which is designed to fit any standard appliance cord normally found in the home. Thus the device can be sold without a cord.
It is a further object of the invention to provide a simply constructed warming device which is shock proof from an electrical point of view, and which is also composed of non-destructible units which are not destroyed in use and which do not cause discoloration or scum formation in use, as have previous devices.
Other objects and features of the invention having to do with the details of construction will be brought out in the following description and claims.
In the drawing:
Fig. 1 is a side elevation showing a bottle in place.
Fig. 2 is avertical section further illustrating the details of construction showing also the separator or bottle supporting plate.
Fig. 3 is a plan view showing particularly the separator plate.
Fig. 4 is a plan view of the unit showing the heating elements and the manner of installation.
Referring to the drawing, a cup shaped container I is provided preferably as a ceramic die casting. This container has a bottom II with three supporting feet l2. The bottom H is made relatively thick and is recessed as at l3 to receive two parallel carbon elements I4 and 15. These elements are positioned and spaced by two projections :6 in conjunction with the other walls of the recesses. One wall of the cup is flattened at I! and is provided with spaced apertures I8 each alined with the carbon elements l4 and [5.
The carbon elements It and I are first sealed in their respective recesses with a water proof composition 45a which holds them firmly in place. The carbons are then drilled and tapped through the holes l8, and contact studs 19 are screwed into the holes. These studs are left projecting from the surface I! in parallel relation. Sealing composition Illa is then placed in the holes l8 around the projections I9.
Above the wall of the cup are two inwardly extending studs 20 which cooperate with opposed notches in a cookie-shaped resting plate 2| or separator. This plate is preferably secured and positioned by any convenient means such as a locking clip or water proof composition. Holes are providedfor the passage of steam upwardly from the heating units to the bottle and also to permit condensation to flow back to the units.
In operation the device may be connected to a source of electricity by any convenient household cord 25 as is now commonly in use on toasters, waflle irons or ordinary household irons. A tablespoon of water is then placed in the cup to form a contact between the elements 14 arid I5.
This water will pass through holes in the plate 2| and is retained in the space |3 between the carbons l4 and I5. The resistance set up will cause heating to take place and water to be evaporated into steam which will further heat the bottle. When the water is entirely evaporated, the heat will, of course, be automatically turned off. The quantity of water is sufiicient to heat a nursery bottle to the temperature desired for feeding.
I claim:
1. An electrically heated nursery bottle warmer to be used with an outlet cord comprising a supporting cup formed of a material having thermal and electrical insulating characteristics and provided within the bottom with a rectangular opening, elongated carbon electrode pieces located within said opening adjacent the bottom of said opening in substantially parallel relation each aligned with an opening in the side wall of the cup, and short straight cored prongs extending from said blocks to a spaced parallel position outside said cup wherein the cored prongs extended are the only conducting means between the electrodes and an electrical outlet cord.
2. An electrically heated nursery bottle Warmer to be used with an outlet cord comprising a supporting cup formed of a material having thermal and electrical insulating characteristics, elongated carbon electrode pieces located within an opening adjacent the bottom of said opening in substantially parallel relation each aligned with an opening in the side wall of the cup, and short straight cored prongs extending from said blocks to a spaced parallel position outside said cup, wherein the cored prongs extended are the only conducting means between the electrodes and an electrical outlet cord.
3. An electrically heated nursery bottle warmer to be used with an outlet cord comprising a supporting cup formed of a material having thermal and electrical insulating characteristics, elongatedelectrode pieceslocated within an opening in the bottom of said clip in substantially parallel relation each aligned with, an opening in the side wall of saidcup and spaced to form a. water rerecess therebetween; and short cored prongs extending from an embedded position in 5 electrical outlet cord.
said electrode pieces through said side wall open ings to a spaced parallel position outside said. cup,
wherein the cored prongs extended are the only conducting means between the electrodes and an ROY R. FISHER.
