T 0 all whomv t conce-m: l
Be it lrnowvn that l, Farra Fam, citizen of the Republic of Switzerland, residing at Berne, Switzerland, have invented certain new and useful Improvements in an Electrio Heating Device for llunging, of which the following is a specication.
The object of this invention is the provision ot an electric heating device capable of being plunged in the substance to be cooked. The heating device is provided with a heating nnit in orm'oic a short tube between the Walls of *which resistance Wire is located to protect the resistance vvire prevent contact oi the latter with the liquid or other substance into Vwhich the heating; device is plunged.
ln the accompa-.nyingn drawing wherein a Y practical embodiment o the invention is the extremities illustra ed Figure l is side elevation, partly brolren away, of the improved electric heating device; C
Fig. 2 is a similar vievv of slightly modilied form ol the device; and
Fig. 3 is an enlarred fragment-ary s ectional viera body or heating unit of the ddeferring' to 'the drav-Jing; in detail the double Walled heating unit is designated by c.; its 'forni is here that el a hollow cylinder but it might also be oval or elliptical. The resistance Wire which is clearly shown in Fig. 3, is coiled in *bis cylinder between layers of n ica said c istance Wire beingancnored in body oit insul ting cement designated el. Each tube e for the lead conducto-r is introduced in an orii'ic provided in the linner Wall of the cylinder and it is then brazed in the heating unit, so that in case ot overheating, apparatus may not be. damaged. in each tub-e e is the com insulated by means or" pearls bea Said conductors beine' Y t l the current to the ln the form ot in n l tivo ful ducting' the co conductors and hai.. ,e ,l is attached -o the tunes opposite. the
heating' unie or cylinder a.
rlliebtorzn illu in ig. 2 has three tubes e oisposed at angles of 120 degrees to and each of the tubes is adapted one another t to receive a conductor f. @ne o' the extremities oit said conductors may be connected to a plug socket, the two Split plugs of which may be screwed oil' and putin one or the other hole, according to the voltage at disposal. The heating unit of said apparatus is divided into two parts which may be utilized independently one of another for llt), respectively 150 volts and which, when connected in series, may supa current till 250 volts.
The disposition oi' the tubes in the interior of the heating cylinder is particularly advantageous, as Well with regard to the durability and rigidity of the device as regarding 'the facility of construction. The tubes be brazed to the interior wall of the heating unit after said Wall has been bored and the edge oi the hole has been ned inwardly as indicated at z' in Fig. 3. he tube is then introduced in the orice and the depression j formed by turning the edge it the opening` inwardly, and is filled by brazing; no damage of the heating unit u is therefore possible, the latter being then placed in a layer of insulating material and the exterior Wall being put over the Whole.
l claim:
l. ln an electric heating device, a double Walled body member, and an electrical resistance element coiled between the Walls of the body member and having the convolutions thereof arranged substantially concentric with the anis of the body member.
2. ln an electric heating device, a. double walled body member, an electrical resistance element arranged between the walls of the body member, electrical conductors connected Withsaid resistance element, and independent tubes receivingl the several conductors and havingr divergent extremities connected with the body member at remote points.
3. In an electric heating device, a double Walled body member, an electrical resistance element arranged between the Walls oi" the body member, electrical conductors connected with said resistance element, independent tubes receivingthe several conductors and having` divergent extremities con nected with the body member at remote points, and an insulating` handle member carried by the extremities ot the tubes opposite said body member.
il. In an electric heating' device, a double Walled body member having openings formed in the inner Wall thereof, the edges of the openings being` turned inwardly, tu-
Vtially concentric with the axis of said body Y walled body bular members secured to the turned edges o the openings and extending from the` body member, an electrical resistance element interposed between the walls' of the body member, and electrical conductors con-A bular members secured to the turned edges of the openingsand extending from the body member, anl electrical resistance element interposed between the walls of the body member, electrical conductors connec'ted with the resistance element and eX- Y tending through the tubes, and beads carried by the portions of the conductors lying within the Vtubular members for'preventing ccntact or. the latter with said conductors.
6. lnan electricheatmg device, a double walled body member, an electrical resistance element coiled in said body'member and having its convolutions arranged substanifionese member, layers of insulating material introduced between the resistance element and the Walls ofthe body member, and'rmeans anchor-ing the resistance element between the layers of insulating Ymaterial and maintaining the convolutions or" the resistance element in spaced relation. Y
7. ln an electric heating device, a body member consisting of spaced inner and outer walls having sections of the edges brought together andconnected, theYV inner wall having openings therein and having the edges of the openings turned inwardly, 'tubular members secured in the openings, and an electric resistance element insulated from and arranged between the walls of the body member, and electrical conductors having connection with the resistance element and extending through ythe tubular members.
In testimony whereof alxmy signature in presence of two' witnesses. l
