Qriginal application filed Eecember :23, 1910, Serial $98,837. Divided and this application filed February 21, 1911. Serial in. 610,056.

and will be found particularly desirable for use in heating surface cars, especially trolley cars, althouglrit is not limited to such use and may be available for other as for instance in heating garages and other places where it is advisable that the source of heat should be located outside of the apartment to be heated.

The invention consists in the provision of means whereby heat may be rapidly and economically gcneraterfl from a heating pipe in which it radiated tor the heating of the apartment in w i" h it is situated.

The particularinvent ion forming the subject matter oi this application is principally a division of a prior application filed by me December .23, 1910, Serial No. 598,887.

lvly invention may well be employed in connection with the heating system disclosed in my application for Patent No- 595,119, tiled December 1, 1910, although it is not arily limited thereto. y invention has for its object to provide an improved form of heater unit for use in connection with the term of heating pipe Cllcl 59o desirable form in which my intuition may be embodied is illustrated in the accompanying drmvings wherein,

Figure 1 illustrates a longitudinal section of a. structure, as for instance .a car body, which is applied heating pipes constructed arcordiug to my invention. 'Fig. 2 is a cross section of the same. Fig. 3 is a vertical section of an extcnson on said heating i n' and oi a heater pocket formed therein ot th"= heater unit within the said pocket. Fig. is a cross section on the line ll-"*4 oi 3.

in my said prior application for patent filed December 1, 1910 a heating pipe is employed which is only partially filled with vaporizable lirpiid and in which the balance of the pipe contains a. vacuum, and the said pipe is sealed to prevent any breaking of vacuum. This permits the quick vaporg iaation oi? the liquid within the pipe upon .d in my said amplication Serial No.

heat being applied to the end of the pipe containing said liquid, and a rapid radiation of heat from the pipe is thereby obtained.

My present invention has for its object to induce a still more rapid vaporization of the liquid within thepipe, and a consequent more rapid radiation of the heat therefrom. In carrying my invention into effect I preferably employ a construction of heating pipe, such as illustrated in. my application of which this is a division, which consists in forming at a point in said pipe, and preferably at the end of a vertical part thereof which constitutes the lowest point in the pipe, a double walled extension, the inner wall of which is open to the atmosphere at its outer end and closed at its inner end forming a pocket for the reception of a heater. The thickness of the sheet of liquid contained between the two walls of the pipe at said extension is very slight and may be as little as one-eighth of an inch. The inner wall of the pocket I preferably form of a thin tough metal which is a good heat conductor, and for which purpose I found copper to be admirable. Within the pocket thus formed I insert a heater unit, and the present invention is directed. to the particular construction of such heating unit and the manner of assembling the same and holding it in place in the heating pipe. The said heater unit is preferably so constructed that there shall be no air insulation between the heater and the inner wall of the pocket. in

other words, I prefer to have close contact between the said parts and if any spaces should exist they are preferably filled with some suitable heat conducting substance as sand.

vention illustrated in the accompanying as having upper portions a which are situated within the space to be heated, in this instance a trolley car, and may be located beneath the seat and behind the riser a. which. is perforated to permit the passage of heat... This pipe as shown has a return bend drawings, the heating pipe A is illustrated .said metal jacket is removable from the poor and a downward inclination terminates in a part a which is conveniently located and extends below the car fioor. For the purpose of assisting the rapid radiation of heat from the heating pipe A, I may inclose the same in a coil of wire a", which encircles the periphery of the radiating portion of the pipe within the trolley car, as illustrated, and has, the effect of increasing the rapidity of radiation from the pipe.

Upon the lower part a is formed an extension B which is illustrated as slightly enlarged and has secured to its outer end a tubular socket b which is suitably attached to the outer end of the extension B, as for instance by brazingi and is closed on its inner end forming it tubular socket which is adapted to receive the heater unit. The said extension B is suitably secured to the por tion a of the heating pipe A, as for instance by being screw-threaded thereon, as illustrated, although other form of connection may be employed if desired.

The space between the outer wall which I shall designate Z) of the said extension B and the inner wall 2') is filled with the liquid contained in the said lower part of the pipe, andtthe distance between the said outer and innei: pipes is very slight and may be as little as one-eighth of an inch. An electric heater is placed Within the pocket produced by the inner socket b and heats the liquid between the walls 2) 3/. The particular heater with which the present invention is concerned is designated as a whole by the letter D. This comprises an outer metal jacket al in which the heater proper is in sertcd and wherein it is closely packed. The

pocket for the purpose of insert-ion of the heater or for repairing the same, and fits closely within the inner wall This jacket (i may lgc of some good conducting metal as for instance copper. Within this jacket is placed the heater constructed subtantially as illustrated in Fig. 3 of a porcelain core 0 upon which is wound a heating wire 0" which is suitably insulated, as for instance by being covered with a coating of enamel c which covers the said wires and insulates them one from another to prevent short circuit. The heate thus constructed is placed within the metal jacket (Z and packed therein with a su table heatconducting" substance 0* for iieh sand is well adapted. A cover Hit then be applied to the said heater and heir i pl e by binding screws 0 0 and the .aid be inserted within the pocket to used by the inner wall (3, and screws in then applied to hold the heater in place. circuit is completed through the metal rod and wire 0 and leadingdn wire The particular manner in which the heater unit is held in place, which is illustrated, i only one of tightly packed therein and the cover 0" applied. thereto and suitably held in place the binding screws and that the sembled structure inay then easily and conveniently be inserted within the pocket in the extension B and held therein by any suitable means. It will also be perceived that the resulting structure is one capable of inexpensive construction, and it is remarkably efiicient in operation. It: is simple and easy to repair and if necessary a heater may be removed for repair and a fresh one inserted in a short time and thereby the utility of the rolling stock of railroads is not impaired by reason oi. any delay in repairing the heating apparatus.

It is not to be inferred from the part-i011 lari't-y with which have described the details of construction of the said heater that my invention is necessarily limited to all of these details, as equivalent devices may be,

substituted and changes made therein within the limits of the appendedclaims. i
