A TTORNE Patented dune 10, 1930 was s'rA rss AARON H. GOLDSMITH, E CLEVELAND, OHIO ELECTRIC BABY-BOTTLE WARMER Application filed November 14, 192?. Serial lt'o. 233,183.
The objects of the invention are to provide an electrical heater in which nursing bottles for infants or any liquids contained in receptacles can be quickly heated at any adapting it in every way for practical do-' mestic or hospital uses, and filling a long felt want in household and hospital appliances.
The device includes the employment of a thin removable metallic inner tube or shell, constructed of soft, heat-conducting, and radiating material, a coil of heavily insulate'd resistance wire encircling the same, and efficient fastening means for the wire permitting it to be readily attached to the tube and detached therefrom for substitution of a new heating element or of one of greater or less heating capacity.
The invention also includes an outer casing for the inner tube, a base therefor upon which the inner tube and outer casing are mounted in spaced relation to each other, thus providing a closed air chamber in which the air is heated to retain a heated atmosphere about said inner tube; also a detachable bottom disc is provided which serves to cover the enclosure in the base in which the electrodes of an electric circuit and wire attaching means are secured. This disc may be perforated for ventilation, if desired.
In this device the inner tube does not serve as the receptacle for liquid, but the liquid receptacle such as an infants feeding bottle is inserted therein and substantially fills all the space therein, so as to be quickly heated by contact with and radiation from the walls of the inner tube; also the inner tube may be provided with partitions or dividing means, thus making it, when constructed of large size capable of use for heating a multiple number of vessels such as nursing bottles.
The invention is hereinafter more fully described, illustrated in the accompanying drawings, and specifically pointed out in the claims.
In the accompanying drawings, Fig. 1 is a vertical central section of the device; Fig. 2 is a front elevation of the metallic inner tube; Fig. 3 is a plan of the insulation upon the resistance wire;'Fig. a is a plan of a larger form of inner tube, showing detachable means for separating a multiple number of liquid receptacles; Fig. 5 is a front elevation of the base of the device showing the electric terminals for the heating element and the spaced shoulders thereon; and Fig. 6 is a vertical section showing an alternate form of metal inner receptacle.
In these drawings 1 is the inner tube, preferably formed of soft sheet iron, to make it quickly absorbent of heat-2 is a coil of resistance wire, which is looped over a suitable retaining device such as an eyelet 3, adjacent to the top of the tube, and is thence passed in close spirals around the outer surface of the tube, and the extremities after passing around the spaced eyelets 4: and 5 are led to the terminals 6 and 7 in the base B, and secured thereto by means of nuts '9, 9, and insulated washers 10, 10, as shown in Fig. 1. These terminals are provided with shoulders 11, and screw threaded inner extremities 12; 13 is a milk bottle inserted in the inner tube and substantially filling the same.
The lower edge of the inner tube 1 rests detachably upon the annular shoulder 15 of the hollow base 8 and fits tightly against the vertical side 31 of the raised central portion 14. Through openings, 16 in this shoulder, the resistance wires 2 pass.
The base is provided with a second annular shoulder 17 against which the covering disc, 18, is secured by'means of the central bolt, 19, the head of which is sunk in a recess, 20, in the top wall 14: of the base. This disc may be provided with "ventilating openings 33, so that the base will not be overheated.
The annular shoulder 15, serves to separate the inner tube from the external casing 21, and forms the bottom wall for the annular space therebetween, and the annular space at the top of the tube and casing is enclosed by means of the metallic rin 22, having an annular recess, 23, in whic the upper edge of the inner tube is inserted, and the outer edges of the ring and easing are preferably rolled together at 24 for further security of the parts, which, while not water tight, should'be rigidly secured together.
The outer casing 21 rests upon a third shoulder or-enlargement 30 of the base and fits tightly against a vertical annular face 32 of the base andmay be rigidly secured by means of bolts or screws 34 to the raised portion 32.
A porcelain handle, 25, is secured to the casing wall by means of the bolt, 26.
The resistance wires are enclosed in a double or multiple wrapping of asbestos yarn for complete insulation and to prevent them from unraveling the asbestos yarns in adjacent layers are wound in reverse directions as shown in Fi 3. This also insures perfectinsulation which is much safer than wrapping the naked wiresupon thin sheetasbestospaper, since the coils are apt to. slip thereon and cause a short circuit or the sheet asbestos may become charred or broken and lose its efiiciency as an insulation.
H In Fig. 4 aspider, 39, is shown, which may be employed in large sizes of the deyice, to keep a number of liquid containing ber havin vessels separate, and may then serve as a cooker for simple cooking.
In Fig. 6 a supplemental or alternate receptacle 40 is shown, preferably constructed of aluminum, and provided with a bottom 41 formed integrally or with edges rolled into the edges of the sidesin place of soldering. This ermits the device to beused as a sterilizer or doctors or dentists small tools, for boiling water or cooking infants foods.
A bail 43 at the top is used for lifting it out of the container, and a flange 42 rests heating coil enclosin said inner shell, a hollow lower base member and a bolt connecting said base members, terminal contacts in the space between said bases, said lower base being provided with ventilating passages,
2. In a heater for an infants bottle, in combination, a hollow base having a raised central portion and provided with horizontally spaced shoulders at different levels, an inner metallic shell mounted upon the upper one of said shoulders, amouter shell mounted upon the intermediate one of said shoulders, and a bottom disc mounted upon the lower one of said shoulders, connecting means between said raised portion and said disc, said disc being provided with ventilating openings, an'annular cap rigidly connecting the upper ends of said outer and inner shells, entering wires secured in said hollow base, and a resistance wire wrapped with flexible insulation coiled around said inner shell. In testimony whereof I afiix my signature.
AARON H. GOLDSMITH.
upon the flanged ring 23-at the upper end of the bottle.
Having described the invention, what I claim as new and desire to secure by Letters Patent is:
1. In an electric heater for infants bottles and analogous uses, a hollow base memtwo horizontal shoulders in its vertical e ge, an inner shell resting on the inner shoulder, an outer shell resting on the outer shoulder and an annular cap ring having its inner and outer edges interlocked respectively with the upper edges of said inner and outer shells, an insulated wire
