To all whomit 'may concern.'
Be it known that l, Wimmer ll'. lirrnr, a citizen of the United States, residing at Bloomfield, in the county of Essex and State of New Jersey, have invented certain new end useful im )rovenients in. Electric l-leating Auparatus, of which the following is a speciiiczition.
My invention relates to improvements iny electricheating apparatus having particular reference to devices for warming plates, dishes and similar articles in ovens,iair tight closets end like receptacles and comprises a device to be opere-ted end controlled by the application of direct, alternating, or intermittent electric currents to a suitable resistance and the passage of air currents tl'ierethrough or thereover.
ln the following described in connection with the accompanying drawings an embodiment of thc invention utilizing a direct current, the features thereof beiner more particularly pointed out hereinafter in thc claims.
-ln the drawings Figure l. is a longitudinal sectional View oi an air tight receptacle illus* trating the. heat-iin,f device as mounted in e. separate compartment; Fig. 2 a lons-itu dinal sectional view illustrating;` a modiiied .forni ol the heating device as applied to one oi the Walls or casing of en nir tight receptacle; Fig. 3 is a longitudinal sectional View illustrating;` a modified form of the heating device supported Within an airtight rei-cp taclc or nn ar tment at a distance from the walls; and ilig. i is a vert-ical sectional View on the line A -v--l of Fie. 3.
Similar numerals or reference indicateI similar parts throughout the several views.
1 indicates` an air tight receptacle or compartment comprising an end woll 2, sidel top and bottom walls 3, and a door f-l attached to one ol the side Valls 3 hy ineens of hinges 6 an auxiliary inoun d 'in seid rc.- ceptacie at the resi Cdn :sod the/reci.t and hes suit anlyglormod therein air inlet holes Y, and ourlet holes Sjsuid auxiliary wall d and end Wall 2 forming su p porting ineens for the bottom. plate 9 end (leilecting plate 10 of the .renting device 11.
12 are a series or current carrying and heut generating electrical resistances suitably mounted on. insulating studs or blocks 13 fastened-1.o the inner rece ol end willi Z, the
. 1. ,i iA
uppermost oi sind resiste-1 s er in eim-y tact' with the main or electric lead wire 14 and the lowermost in contact wlth return wire 15, the intermediate portions thereof being adapted to be connected in series by means ol wire connections '16.
As illustrated in Fig. 1 of the drawings E indicates the manner in which the plates and dishes are placed in a receptacle or compartment, the arrows indicating the direction in which the air is forced during the heating of the seme.
Referring to Fig. of the drawings 17 indicates a heating device rigidly fastened to the inner face of end wall 2, said heating device comprising front and side walls 1S, a bottom 19, in which are air inlet holes 20, and an air outlet means comprising a screen mesh Z1 suitably mounted on the to of liront, end and side Walls I8-, the heate air followingr the course as indicated by the arrows. rlhe resistonces and means for su porting the saine in said air tight receptac e or compartment are as described above.
.Referring to Fig. 3 the heating device comprises side walls 22, front and back walls 23 and bottom 124, said front and bottom walls having' formed therein air inlet means 25; the air outlet means comprises a screen mesh 26; the device together with the resistanccs and means for supportingr the same are heid in position within the air tight receptacle or compartment 1 by meansof bracket arms 27.
The electric wiring as shown in Fig. 4 of the drawings illustrates the application of multiplo winding, While that shown in Fig. Il. illustrates the saune device Wound in series.
The o poration ofthe device is as vfolli'm's Plates, dishes, and articles of that nature may be placed within the air tight rece-ptacle or compartment 1 and the door 4 closed. llurrent is then permitted to pass from electric main 1lijthrough resistances 12 causing the seine to become heated to es high degree or heut as is desirable, the current being controllable by any suitable means (not shown). The air in seid receptacle enters the heating device through the inlet holes, passes over the resistances and circulates in a current in the direction indicated by the arrows'.
it is obvious that varied degrees of' heat may be obtained by regulating the amount or current used, und that the same may be controlled and 'the distribution of heat oouaiized hy the ineens described. It is iurM
