ELECTRICAL HEATER AND EXPANSION CO".-
Specification of Letters Patent.
Patented June 11, 1907.
Application filed September 13,1906. Serial No. 334,409.
To all whom, (It may concerto.-
Be it known that I, MrLroN H. SHonN- BERG, a citizen of the United States, residing at the city and county of San Francisco and 5 State of California, have invented new and useful Improvements in Elettrical Heater and Expansion Coils, of which the following is a specification.
My invention relates to a heating appa- 1o ratus.
It consists in the combination of one or more tubes through which heat is transmitted, said tubes having an elastic expansible electrical resistant conducting coil lo- I 5 cated within the insulated lining, and connections whereby an electrical current may be passed there-through, and in details of construction which will be more fully explained by reference to the accompanying drawings,
20 in which'- Figure 1 is a vertical section. Fig. 2 is a perspective view.-
It is the object of this invention to provide a device in which the elasticity,of an insu- 2 5 lating interior coating and of a" conducting coil, may be utilized to maintain a suiliciently close contact between these interior parts and the tube, so that the greater portion of the heat derived from the resistant coil will 0 be transmitted through the tube to heat the medium which may be in contact with the tube.
A is a metal tube of which there may be any desired number arranged parallel with 5 each other and having the enils supported in. suitable bearings. Within this'tube an insulating sheet 2 is caused to expand; Mica having a certain amount of elasticity may be cut to such a size thatit will just fill the inteo rior of the tube wheh expanded, and being introduced its elasticity will cause it to expandand fit snugly againstthe interior of the tube.
3 is a coil of naked wire which is a good electrical conductor. This coil is of such 45 diameter that it will fit snugly within the ining the best transmission of heat through the substance of the tube. 1
4 are poi celain or other non-conducting bushings inserted in the ends of the tube A, and within these bushings are fitted the plugs 5 with which the ends of the coil 3 are conture of the coil will be elevated, and the tube or tubes A will be correspondingly heated. in Fig. l, l have shown tubes of this sort passing through an exterior chamber 8 which may contain water or any heat conductor through which the heat may be utilized.
in Fig. 2 I have shown the tubcsA arranged within a frame or container 0 so that the conductor to which the heat is to be transmitted may be laid upon the tubes in the form of..a metal plate which will serve for cooking purposes.
As shown in this connection, the plugs 6 through which the line wires, 7 communicate with the coils interior to the tubes, connect with the opposite ends of the series. one of the line wires 7' connects through the coil with in the first tube A, thence through a transfer plate 10 with a second coil at the opposite end from the plug; thence the current returning through theinteriorcoil is again I transferred to the thirdtube, and its coil, and
so on through as many of these coils and tubes as it may be desirable to use in a single series, and from; the final tube connection is" made to return the current through the line wire 7.
In place of a mica insulation I may ploy any suitable insulating substance which can be interposed bet'iveen the interior of the tube and the coil, the expansion of the coil acting to form a close contact and more perfect transmission of the heat, without reference to the particular insulating medium.
Having thus described my invention, what I claim and desire to secure by Letters-Patent is 1. An electrical heater consisting of an ex- Thus,
'terlor tube, an elastic insulating sheet expanded to tit closely Within the tube, an electrieal 'esistztnt coil expendedto fit, the interim of the insulating sheet and retain it in close contact with the tube, and connections whereby an electrical current may be passed through the coil, said connections including non-conducting bushings fixed in the end of the tube, end plugs fixed in the bushings and connecting with the coil.
in an electrical heater, it heat conducting tube an insulating sheet fitting Within the tube, said sheet consisting of a piece cztpable of being coiled to initially enter the tube and then expansible to fit snugly against the interior of said tube, an elastic eoil having such diameter as to expend and make close contact between itself, llt insulating sheet end the interior of the tube and eonneetions whereby an electrical current may be passed through the coil to heat the latter and the tube, and a mediliin to be heated with which the exterior of the tube is in contact.
In testimony whereof I have hereunto set my hand in presenee ol' two subselibing witnesses.
