ELECTRIC HEATER.
Specification of Letters Patent.
Patented Aug. 3,-1 9C9 Application filed July 17, 1907. Serial No. 384,221.
Be it known that we, CHARLEs E) Tnnw- HELLA and EVERETT D. HoLLnY, citizens of the United States, residing at Forestrille,
'county'o'f Hartford, State of Connecticut,
' heat unit to the part to be heated.
.and j'open at the opposite, end to receive heat 'unit of any preferred construction and Another object of the invention is to provide means for distributing the heat over the surface to be heated and to provide for an efficient contact between the heat-distributing element and the surface to be heated.
Another object of the invention is to provide means whereby the heat will be conducted from the heat unit only to the part to be heated, and whcrebyliability of a loss of heat due to induction, or from the adjacen bodies .not intended to receive heat, will be avoided- 'Other objects and advantages aswell as the novel details of this construction will be specifically described hereinafter, it being understood that changes in form, size and minor details of construction may be resortedto without departing from the spirit of the invention 'or sacrificingany of the advantages thereof.
In the drawings: Figure 1 is a view partly in elevation and partly in section of our inv ven't'ion applied; Fig.2 is a bottom view of the same; Fig. 3 is a side elevational view; and-Fig. 4 isa' perspective view of the heat distributing and heat element receiving device. g
The invention is-illustrated as being applied .toa liquid heater of which 1 designates the receptaclei 'and 2' the base. The receptacle 1 is provldedfwith a bottom 3 against which the heater is adapted-to bear. This heater is illustrated in Fig. 4 as comprising a cylindrical bodypor'tion l closed at one end a provided withanjmsulziting block 5, and the usual contact 6-. h In order to efficiently and expeditiously distribute the heat from-the body portion 4, we provide a plurality of 'heat distributing wings 7 arranged in paral lelism and having their ends projecting from opposite sides of the longitudinal center of the body portion 4, and arranged so that their upper edges 8 may lie snugly against 1 the lower surface of the'bottom 3. -Thcse wings are illustrated as graduating in length, from, the respective ends toward the center, and the purpose of this arrangement is to provide for a circular bottom, so that the heat will be distributed from the body portion 4 over the entire lower surface of the ottoni 3 and, therefore, insure a perfect dis tribution of the heat.
able that all parts of the-wings 7 be kept in perfect contact with the bottom of the receptacle (or other element to be heated) and in order to provide for this perfect contact, we arrange adjusting devices, shown as screws '9, of which there maybe any number, and between which and. theheateris an insulating element 10 comprising a fiat body which bears efficiently against the body of the heater 4, so that when the adjusting elements 9 are screwed through the support 11, the
in the bottom 3 may be provided for by regulating the adjusting devices.
In order to give the best results it is desir heater blades may be forced in intimate contact with the bottom 3, and any inequality- The opening 12 in the base 2 of theheater is slightly elongated to provide for a vertical adjustment of said heater, but the heater is 'insulated away from the base by an insulating bushing 13, so that any heat which is communicated. to the heater from the heat unit can pass only to the element to be heated, in this instance the bottom 3. It will also be observed that one end of the heater may be spaced away from the wall of the base 2 on account of its being supported 'bythe element 10. The support 11 may be fastened in any convenient manner, as by the flanged ends 14 and 15, either riveted or screwed to the base, as practice mayfind most convenient.
The receptacle 1 is illustrated as being in effectan integralpart of the base 2, so that the bottom 3 becomes in efiect a heating plate, and the liquidor other material to be heated, as the case may be, therefore, comes heater direct to the element tobe heated,
and that theheating will be assured in an efiifcient and expeditious manner.-
What we claim is-- i. In an electric heater, thecombination faith a heat unit receiving member a plurality f heat distributing wings extending from saidheat unit receiving member, of a heat 'nnit provided with an insulating block and a contact, said heat unit being constructed to enter said member.
2. In an electric heater, the combination with a cylindrical body portion closed at one end and open at its other end, a plurality of heat distributing members arranged in parallelism and projecting from opposite sides of said body portion, of a heat unit adapted to.
enter said body "portion and provided with an insulating block and a contact.
3. In an electric heater, the combination with a hollow body portion and a heat unit and a heater constructed to enter said. body ortion, of means to adjust saidbody portion in to immediate contact with an element to be cannerheated, and insulation between the adjusting carried b said base heat distributin means carried by. said member, and. an insulation between the base and said member.
5. The combination with a member hav ing a base, of a heater carried by said base, a heater support carried by the base, and adjusting means carried by said support and adapted to force said heater into intimate contact with said first named member.
6. The combination with a device to be heated, of an electric heater below said device, an insulating member below said heater, and adjusting means below the insu lation, said adjusting means being effective for forcing the heater into contact with the device to be heated.
In testimony whereof, We hereunto affix our signatures, in the presence of two witnesses.
