HEATER UNIT FOR PIPES.

Applica-tionled July 14, 1922. Serial No. 575,106.

To all wimmt 11m- 1] con cern.:

` Be it known that I, JOHN E. KESTLER, a

citizen of the United States,r4 and a resident of Fountain Inn, in the county of Greenville and State of South Carolina, have invented certain new and useful Improvements in Heater Units for Pipes,*of which the f ol lowing is a specification.

This invention relates to a heater unit for pipes.

The object of the invention is to provide a heating unit which may be applied to pipes taken substantially on the line 2 2 of Fig' 4ure 1.

Figure 3 is a vertical sectional view of the heater unit.

Figure 4 is a similar sectional view taken through the heater and at right angles to the views shown in Figure 3.

Referring to the drawings more particularly, the heater may consist in a casing C, which is preferably cylindrical, and has -its interior lined with asbestos as at 5L. The lower end of the casing is provided with a closure 10, while its upper end is open and fitted with a cap K, said cap having a downwardly extending flange 11 to form a tight closure with the casing and supporting an electric incandescent lamp 12, the base o said lam being secured to the cap by the means o boltsv or the like as at 13, and said cap being provided with a suitable opening through which there may extend the cord 14 for supplying the -lamp 12 with electric zurreht. The casmgC may be provided with a pair of wings W which are resilient and arcuate in shape. Within these wings there may be positioned a lining of insulating materbpl such as or the likel as indica wings preferably extending below the casing erally at 15 and which may, extend enti y' the length` of the wings W, said C, fas shown, and these extended port-ions being integrally joined as at 9. The interior v surfaceof the lining or insulation 15 should be arcuate as at 1.6 so that this lining may fit about a pipe P.

'At a point in horizontal alignment with the lamp 12 there should be provided an Vopening17 whichshould extend through the insulation L of the casing C, the casing Cv itself, and the lining or insulation 15.

As is shown the wings W substantially encircle the pipe P to be heated and these wings theretore substantially form a casing' 'wlth insulating material therein adapted to surround the pipe to which the lamp 12 is adapted to supply heat through the opening 17.

For further protecting the pipe P, there is provided an extension generally indicated by the reference character E and which consists in a pipe section recessed longitudinally `and made of resilient material. Suitable insulation 18 is provided for this sectionpof the pipe. The lower end ortion of the extension is not lined with-insu ation and is adapted to telescope about the wings W. i

It .is thought from the description heretofore given that the operation of this `present device may be entlrely and clearly understood.- The device is particularly useful in the winter for preventing freezin water pipes in the house or buildings w ich are exposed to extremely low temperatures.

The device may be applied to a pipe in a short interval of time and with a small amount of labor, and the cord 14 may be led to a suitable source of electric current Sup-r ply for energizin the lamp 12. The removable feature o theldevice is valuable in that it permits the same to be sold at any store and sold in sizes so that they may be utilized in connection with any diameter of Pipe I claim: f i i 1. In combination, a pipe, insulation about said pipe, said pipe having an exposed portion with respect to said insulation, an enclosure arranged in close relation to the insulation about the pipe, and said enclosure havin anopening' 1n register with the expose portions of said-pipe,

and means whereby a heating medium mayV -be provided `in said enclosure.

`2. In combination, rounding said p ipe,

a pi a casing sur-- iusuilzion interposed between said casing and pipe, said casing and insulation having aligned openings to expose a portion of said pipe, and a heating chamber communicating with said openings.

3. In combination, a pipe, a casing surrounding said pipe, insulation interposed between said easing and pipe, said casing and insulation having aligned openings to expose a portion of said pipe, a second casing having an opening comi-nunicating with said openings, and means for positioning a heating element in the last named casing.

4. In combination,l a pipe, a casing surrounding said pipe, insulation interposed between said casing and pipe, said casing and insulation having aligned openings to expose a portion of said pipe, a second casing having an opening communicating with said openings, and means for suspending an electric lamp in the last named casing.

5. In combination, a pipe, a casing sui;- rounding said pipe, insulation interposed between said casing and pipe, said insulation and casing having aligned openings to expose a portion-of the pipe, a second casing carried by the rst named casing and having an openingeommunicating with the opening of the first named casing, and a heating chamber positioned in the second casing. n

6. In combination, a pipe, a casing surrounding said pipe, insulation interposed between Said casing and pipe, said insulation and casing having-aligned openings to expose a portion of the pipe, a second casing carried by the first named casing andhaving an opening communicating with the opening of the first named casing, a heating chamber positioned in the second casing, and an extension from'the irst named casing encircling other portions of the pipe.

7. Inl combination, a pipe, a casing surrounding said pipe, insulation interposed between said casing and pipe, said insulation and casing having aligned openings to expose a portion of the pipe, a second casing carried by the first named casing and having an opening communicating with the opening of the first named casing, a heating chamber positioned in the second casing, an extension from the rst named casing encircling other portions of the pipe, and insulation material interposed between the casing section and the pipe.
