I MARCUS MICHAEL-LEVINSON. OF PASADENA, CALIFORNIA.
ELECTRIC HEA TING DEVICE' Application filed April 12, 1921, Serial No. 460,640. Renewed September 10, 1923.
To all whom it may concern:
1 Be it known th'at'I. MARcUs MICHAEL LEVINSON, a citizen'of the United States, residing at Pasadena, in the county of'Los Angeles a'ndState of California, have invented a new and useful. Electric Heating Device, of which the following is a specification.
This invention relates to devices for developing heat by electricity, inclosed in an insulated container.
One of the objects of this invention is to provide a' tubular heater with a centrally insulated heating coil.
. Another object is to provide a heating coil encased within insulatingmaterial within the housing of the device. 1
-Another object is to provide aheating coil embedded in insulating material within the device to the extent to which the device is be heated, having a coarser wire connecting to the coil and extending to the outside and also imbedded in insulating ma-Q lterial in other parts of the device, not to be heated.
Other objects will appear from the following description and appended claims as well as from the acbompanying drawing, in which Fig. 1 is a side elevation of a device em-' indicated at 17 and 16. The wires 8 and 9 bodying this invention.
Fig. 2 1s a slightly modified form of a 1 device also embodying the invention.

illustrated in Fig. 1 is of a.
85'. .a tire and to be useful around. an automobile The devices illustrated in the drawing are provided with a metallic casing, especially suitableto radiate heat, and adapted it form, a durable and compact whole, readily, conveniently, and safely to be handled.
The safety of such-a'device'depends also may occur through its metallic casing.
A device of this type must furthermore be made so that only a limited and suitable, portion of .it becomes suitably heated while the remaining portion retains the possibly The device form to be used for heating 'water and other similar matter by disposing thedevice in such matter', only a proportionally small portion being liable to be heated while the rest retains a temperature easily handled.
This device is also used for use on automobiles, developing enough heat-to vulcanize after hardening, the tube being bent to suit.
In the device illustrated in Fig. 1, the tub '5 with the coil insulatedin it is bent to bring the ends 6 and 7 into a position that the wires 8 and 9 can be connected to the ends6 and 7 The . outer terminations 10 and 11 of the wires 8 and 9 are, provided to allow a connection of supplying current.
The wires Sand 9 are of different type than the coil wire, besides being coarser and preferably practically straight, but also insulated, within the tubes 12 and 13. The tubes 12-and 13 are engaged with the ends of the'tube 5, as indicated at 14: and 15. The opposite ends of the tubes 12 and 13 are embedded in the 'insulating socket 18, as
are preferably insulated by the same kind of material as used in the tube 5, as indicated at 4' in tube 13. .The wires 8 and 9 and the coil 3 therefore entirely insulated from the tubes 5. 12 and 13, and, if the ends 10 and 11 are inserted into a common connecting socket, such .insulation is complete and perfect, so that'the operator cannot receiveany shocks, and no short-circuit can be produced in normal use. p
The circuit is complete, when connected to -a source, from end 10, through wire 8, through coil 3', through wire 9 an back throughend 11 to ,the source, the coil 3 being properly heated and producing a proper heating of the tube 5 between the points 14 and 15 since the coil is made of suitable material to assure such a heating or overheating to a suitable extent.
The device illustrated in Fig. 2 is a slightly modified forn'i, but also designed f to heat only a suitable portion of the outer tube. This device is il ustrated as practi- 'cally straight, but from the following description it will easily be understood that the points 24.and 25, leaving only small the outer form does not materially influence the Working and the principle of the device.
The coil 19 is embedded in the lnSLllatlIlg material 20 Within the tube portion 21. The termination of the tube is closed as indi- "cated at 22. The material, designated'20, is preferably. of the sametype and origin as the material designated 4 in Fig. -1, to; insure the same insulating efi'ect as described with reference to the device in Fig. l. The whole tube from the end 22 to the end 23 is preferably of one piece, cut in at remaining-connections as indicated at 26,
between the tube portions 21 and'27; but a similar and eventually the sameeflect may be obtained and procured by providing dis Npieces of tinctly separate portions 21 and 27, connected by suitable proportionally small metal or Wires. This connection between the portion .21 and portion 27 of the tube is only provided for the purpose of keeping the portion 27 proportionally reaches from the 30 cool when the portion 21 is heated, such small'connections not transmitting too much heat While still forming good "conductors between the tube portions 21 and27, for electric purposes. The tube portion 27 near the cut cuts 24 and 25, A coarser Wire 29, less liable to be heated by the current passing through the device,'is embedded in the same insulating material .20, Within the tube'portion 29, terminating outside of the device, as indicated at 30. The one end of the coil 19 is connected to the tubeend 22',
as indicated. at 31, or'to the tube portion 21 near the end plate 22. The opposite end of the coil is connected to the one end of. I the wire 29, 'asindicated atl32.
The current supplying source is connected to this device at the end 30 of the Wire 29 .and to the end 23 of the tube.
The circuit is completed from the sou-roe,
through end f 30, through th wire 29, 5 through the coil 19, :the tube,- through connecting at 31 with the tube-portion 21, through the connections 26, and through the tube-portion 27 back to the source.
This device is especially suitable for a end 23 tothe point 28,
soldering iron orbolt, since the front end '22 becomes suitably. heated for soldering purposes.
The device may naturally also-be used for many other purposes, the heating of a portion of the device to such an extent to make the device so useful being the principal" point in View.
Having thus described my invention, I claim: 1
1. In an electric heater, an insulating socket, a casin so that both ends terminate within the soc et insulating material in the casing, a heating'coil disposed and embedded centrally within the insulating material Within a portion of the casing, and. a connecting Wire disposed and embedded within the insulating materialiwithin the remainportion of the casing and extending out of t e casing before sa d insulating socket to 1supply electric current to the insulated coi. i
2. In an electric heateiya tube, insulating material in the tube, a heating coil =disposed. and embedded within the insulating material 3. In an electric heater, a tube, insulating within the remaining pormaterial in the tube, a heating coil embedded in the insulating material within a' portion of-the tube adapted to heat that portion of the tu and aconductor con-- nected to the coil'being of material less liableto be heated than the coil and extending outwardly to form the current supply- -ing means for the coil.
In testimony that I claim the foregoing as my invention I have sign the resence of two subscribin witnesses. I ARCUS MICHAEL- L VINSON. Witnesses: O'r'ro- H. Klrumnn, 4 JESSIE A. MANOOK.
