Applicationfledlllanuary 23,1 1920'. Serial No. 353,510.

To all whom t may concern."

a citizen of Greece, andresident of: Green? wichfin the county of Fairfield and State of Connecticut, have invented a .new and 11nproved-.Heateig ofwhich the followingisa full, clear, and exact description. l v

This invention relates to electric heaters and particularly to a batch wvarmer-forconfections. f 1 1 i It is well known to those skilled in the art, that candy or confection batches -harden very quickly after theirrem'oval from.I the heating agent andIit is-therefore necessary to provide means forconstantly heating the batch while working the. same.

it is therefore one of the principal objects of the present invention to produce a heater especially designed for warming confection hatches, the same including -means for regulating the degree ofheat and controlling theprojection of the heat rays to concentrate them upon the batch While Working the same.

Another object of the invention is to provide a portable heater. of the class described, employing a minimum number of parts in order to render the manufacture and production simple and inexpensive.

A further object of the invention is to provide a. heater of the character described which is provided with adjustable means whereby the. area of the heat rays may be increased `or decreased according to the size of the confection batch to be operated upon.

lVith these and other objects in view, which will be more readily apparent hereafter, reference is made to the following description. claims and accompanying drawings forming a part of this application.

ln the drawings;

Figure 1 is a perspective view of the heater` Fig. 2 is a vertical section view therethrough illustrating' the use of the same.

Referring to the drawings by characters of reference, which denote like parts throughout the several views7 10 designates a supporting frame having spaced parallel uprights 11 provided with alined apertures. housing 12 is provided and includes a semicvlindrical rear wall 13 and end walls 1l, the latter being provided with outwardly extendingr trunnions 15 which are received by the apertures in the uprights 11 for supporting the housing to permit or rotation thereof with respect to the supporting frame. Means for securing the housing in any of its adjusted positions with respect to the supporting frame is `provided and said means as here shown comprises a Wing nut 16 threadedly engaged with one of the trunnions whereby the same may be impinged against the upright to secure the trunnion and the housing againsty relative movement with respect to Said upright. The walls of the housing are preferably constructed from inner and outer metallic layersjf17va-nd 18 between Which is confined a suitable heat resisting layer 19 of asbestos. The frame 20 is disposed within the housing and supported thereby,` said frame being designed to carry the heating elements 21 which are in the form of resistance coils arranged in connection with a suitable source of electrical energy through the medium of the conductor wire 22. A regulating switch 23 is yarranged on one of the end Walls of the housing to regulate the degrec of heat desired. The opposite end of the conductor is provided with the usual plug 2st. A handle 25 is provided on the housing 12 in order to permit of the adjustment of the housing.

ln use of the device the heater is arranged upon the supportingsurfacc 26 upon which the batch 27 is worked and the regulating switch 23 turned 011 to produce the requisite degree of heat necessary. As the batch is worked and becomes smaller the degree of heat is increased and the batch moved closer to the heater. As it is moved toward the heater it is necessary to project the rays downward and this is accomplished by loosening the wing nut 1G and turning the housing l2 by grasping the handle 25. The construction of the housing is such as to concentrate the rays upon the batch in order to derive. the maximum benefit from a minimum amount of heat. As the housing is turned to project the rays downward, it will of course be understood that the area over which the heat rays are projected is materially decreased and this feature is especially desirable for the reason that the batch cools as it is worked and becomes smaller.

ll'vhile there has been illustrated and described a single and preferred embodiment of the. invention, it is understood that the saine is merely illustrative and that no limitation is necessarily made to the precise de- BEST VAELALE CGP".

tails of construction as changes and alterations` falling within the scope of the claims nraj-,fv be resorted to when found expedient.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

l. In a heater for confection' batches, a semi-circular housing and reflector, a rectangular frame supported within the mouth of said housing, heating coils carried by said frame, nieansfor adjustably supporting the housing to permit'of the projection of the heat rays therefrom in various angular directions, said means comprising a base having spaced uprights provided with alined apertures, trunnions extending from the end walls of said housing and received by said apertures, and means carried by one of the trunnions adapted to co-act with one of the uprights for retaining the housing in its adjusted positions.

2. In a heater for confection batches, a semi-circular housing and reflector consisting of inner and outer metallic walls, a layer of heat resisting material conned therebetween, a rectangular frame supported in the mouth o said housing, heating coils carried by said frame, and means i'or' adjustably supporting the housing to permit oi the projection ot' heat rays therefrom in various angular directions, said means comprising a base having spaced uprights provided with alined apertures, trunnions extending from the end walls of said housing and received by said apertures, and means carried by one or' the trunnions adapted to co-act with one of the uprights for retaining the housing in its adjusted positions.

P. In a heater ifor confection batches, a base of U-shaped formation having end uprights and an open side, a substantially semicircular hollow heat re'lector having end walls pivoted in said uprights for angular adjustment on a horizontal axis so as to dispose the o'pen Side of thc reflector at different inclinations, and a series of heating coils across the front of the reflector having means of connection with a source of current and provided with means to regulate the degree of heat required.

4. In a heater of the'class described, a base having an open side and end uprights, a heat reflector having end walls pivoted to said uprights and provided with means for holding the same in different angular positions on a horizontal axis, said heater being of semi-cylindrical formation and provide-d with an open side, a rectangular frame in the reflector and having a series of transverse Vertical connectors provided with a series of apertures in horizontal alinement, heat resistance coils mounted in said apertures and carried by the ends of the frame, a switch controlling said heating elements to'regulate the degree of heat required and having connection with a source of electrical energy, and means for adjusting the reflector angularly.

5. In a heater of the class described, a semi-circular housing having end walls and an open side, said housing comprising inner and outer metallic walls, a layer ot' asbestos or other heat resisting material confined-between said metallic walls, variable heat resistance coils at the open side of the housing, a handle at the top ot the housing intel-mcdiately of the ends thereof, and means to support the housing at the ends thereof so as to l'acc. dowuuv'ardly at varying angles.
