ELECTRIC HEATER Filed Sept. ,18, 1929 UNITED STATES ELIAS v. CONKLIN, ori-rznw azoaxgn, :Y.-

Application filed September The present invention is directed to improvements in electric heaters.

The primary object of the invention is to provide a device of this character so constructed that it can be immersed in a quantity of water to effectively and quickly heat the same.

Another object of the invention is to provide a device of this character primarily designed for heating water although not necessarily limited to such use since it can be used for various purposes wherein it is desired to quickly heat a mass or liquid.

Another object of the invention is to provide a device of this character so constructed that one or more heating units may be used in connection therewith.

Another object of the invention is to provide a device of this character which is simple in construction, eflicient in operation and one which can be manufactured at a minimum cost.

lVith these and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed, and illustrated in the acompauying drawing, in which:

Figure 1 is a side elevation of the device.

Figure 2 is an enlarged vertical sectional view through the heating chamber.

Figure 3 1S a transverse section through the housing.

Figure 4 is a sectional view on the line 4-4 of Figure 1.

Figure 5 is a detail view of a multiple socket which may be used in connection with the device.

Referring to the drawing, 1 designates the heating chamber which comprises a cylinder,

preferably of tapered formation, said cylinder being formed from copper and having mounted in its lower end a ring 3, said ring being partly extended from the lower end of the cylinder 2 and being exteriorly threaded for engaging the rim 4 of the closure cap 5, there being a washer 6 interposed between the lower end of the ring and the bottom of the cap in order to prevent leakage.

In the upper end of the cylinder 2 is sea band? which is interiorly threaded, as at 6,'{ for i threaded? engagement with the 9; said hoiisi1'1g having mounted the're'ih rackets 10 whichsupporltthe socket 11,"am1,:ir is -to this socket that the heating uriit'flQ is E removabl-y i'mo'un'ted, there bein a resilient clamp 13 associated with the socliet to positively; maintain the heating element engagedwherein. -'The housing has formed integral therewith the lower end of the tube 14, th'e upperend of'which is closedby a per- Orated Qa MJ *F;ixed to the up'per end n; the tube 14 isa handle l6iwhichconsists of i-nclined' side members 17* unaware connected with verticalinmberstaLS-which, in turn, are connecte'd by ia'; {cross top bar 19. The handle structure i's hollow' so that-the current con ducting wii es QO may be passed therethrough and down through the tube 14 for connection with thesocke't; The 'con'ductor'wires are covered with fire-p roof insulating material. Fig-M6 5 is illu'strated amultiple socket engaging memberlso that two heating units, as}indicated inudotted lines'at- 21, may be attached tb the socket 11 when desired." It will,'&of-cour'se,' be understood thatthe number of heating units' may be optional and maybe of arly-standard 'make'or' size.

Byproviding thetube-M' at its upper end with the perforated cap 15, the excessiheat may lbe'gdiseharged .lfrom'theheatingchamher; and; in worries-a protect". the: hands of the operator, a deflecting plate 23 is supported by the handle immediately above the perforated cap.

Since the cap 5 can be readily removed, the heating unit may be removed or replaced as occasion may require, and should the socket become in any way inefiicient, the housing 9 may be conveniently removed so that repairs may be easily made.

From the foregoing, it is thought that the operation and many advantages of the herein described invention will be apparent to those skilled in the art without further description and it will be understood that vari ous changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the in vention.

hat is claimed is:

1. A heater of the class described comprising a cylinder, a housing threaded in the upper end of the cylinder for detachable connection therewith, a tube rising from the housing and having 'a handle carried thereby, a socket mounted within the cylinder, circuit wires leading through the handle and tube and connected with the socket, and a cap removably engaged with the lower end of the cylinder. 1

2. A heater of the class described compris ing a cylinder having a cap 'detachably con-' nected with its lower end, a housing having threaded engagement with the upper end of the cylinder, a tube rising from the housing, a handle supported by the upper end of the tube, said tube having a perforated cap thereon, a deflecting plate carried by the handle, and circuit wires passable through the handle and tube, and a socket mounted within the cylinder and connected with the circuit 25 wires.

3. A heater of the class described comprising a cylinder, a ring fixed in the lower end of the cylinder, :1 cap threaded upon the ring, a band fixed to. the upper end of 30 the cylinder, a housing threaded in the band,

brackets carried by the housing, a socket supported by the brackets, a heating unit, engaged in the socket, a tube rising from the housing, a handle connected with the tube,

35 and circuit wires leading throughthe handle and tube and connected with the socket.

4. A heater of the class described comprising a cylindrical heating chamber, a" tube connected with the heating-chamber, a heat-- ing unit mounted in the chamber, a handle carried by the upper end of the tube, saidtube having a perforated cap in its-upperv end, a deflecting plate carried by the handle, and circuit wires leading through the handle 5 and tube and connected with the heating element.

In testimony whereof I afiix my signature.
