- RADIATOR.

Specification of Letters Patent.

Application led January 2, 1919. Serial No. 269,367.

T o all whom it may concern:

Be it known that I, HUBERT C. ELLIS, a subject of the King of Great Britain, and a resident of Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Radiators, of which the following is a full, clear, and exact description.

The invention relates to radiators. l

One object of the invention is to provide an improved radiator of that type in which inner and outer pipes are used and which is simple in construction and efficient in operation. A further object of the invention 1s to provide an improved radiator of this type in which there is provision for inducing circulation through the pipes.

The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings: Figure 1 is a vertical longitudinal section of a radiator embody-- ing the invention. Fig. 2 is a plan of the base of the radiator. Fig. 3 is a vertical transverse section taken on line 3 3 of Fig. .1.

The improved radiator comprises a cast base 1 from the top of which extend the outer heater-pipes 5 which have their upper ends closed, as at 6, and their lower ends open and secured in the top wall 7 of the base. The latter is formed of a bottom wall 8, side walls 9 and said top wall 7, all integrally formed. A transverse wall 10, also integral' with the base, is connected to the top wall, as at 11, and slopes downwardly toward the other end of the base where it is connected by a vertical wall 12 with'the bottom wall 8. This transverse wall divides the space in the base into a supply-chamber 13 and an outlet-chamber 14. The transverse wall and bottom wall are parallel and are both inclined. The inclination of the bottom wall causes all condensation to pass to one end of the inlet chamber. A supply-pipe 15 is connected to one end of the base to deliver live steam into the chamber 13 and an outlet pipe 16' is connected to the opposite end of the base to carry off the condensation and serve as a return pipe for the heating fluid. Tubes 17 have their lower ends open and secured in the transverse wall 10 of the base and extend upwardly in the pipes 5 to conduct the steam to a point near the upper ends of said outer pipes. Webs 18 are formed in the base between the transverse wall 10 and'bottom wall 8 to reinforce the transverse wall. A small jet pipe 2() is connected to the wall 12 and terminates in the return pipe 16 to discharge any condensation in the supply-chamber 13 into the return pipe, a pocket 21 being formed in the inclined bottom 8 into which the condensation will drain. This connection between the supply chamber and the return pipe also serves as a jet through which steam' will pass whenever the radiator becomes air bound, to draw the air from the heater pipes into the return-pipe.

In operation,'steam entering chamber 13 through pipe 15 passes upwardly through the inner pipes 17, to the lupper ends of the outer pipes 5, thence downwardly into the chamber 14 to the return pipe 16. This type of radiator is simple in construction and has been found to be eiiicient in operation.

The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention.

Having thus described the invention, what I claim as new and desire to secure by Letters Iatent, is:

1. In a radiator, the combination of a base having an inlet at onev end and an outlet at the other and a transverse wall dividing the space in the base'into a supply chamber and an outlet chamber, heater pipes in communication with said chambers, and a jet pipe connected to the supply chamber extending into the outlet chamber and adapted to draw the air out of the radiator pipes.

2. In a radiator, the combination of a base having an inlet at one end and an outlet at the other and a transverse wall dividing the space in the base into a supply chamber and an outlet chamber, heater-pipes in communication with said chambers, a drain pocket in the bottom of the base, and a jet connected to said pocket and adapted to draw the air out of the radiator pipes.
