Y IMPROVEMENT IN STEAM-RADIATORS.

Specification forming part of Letters Patent No. 179,027, dated June 20, 1876 application filed December 9, 1875.

To all whom it may concern:

Be it known that I, JOHN T. Kn LY,'of Pittsburg, in the county of Alleghenyand State of Pennsylvania, have invented certain new and useful Improvements in Steam-Radiators; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to'rnake and ing the interior pipes loose at both ends, and

providing them with steam-traps, as hereinafter described and claimed.

In all radiators of this description the interior pipe is fastened at one end necessarily, and steam is not necessarily forced to circulate, since it can pass off through the openin g for water-waste without circulating at all.

Referring to the drawings herewith, my invention is adapted to the form of radiator having upright pipes A, closed at top, and open at bottom into the upper of two chambers formed in the base B. They are simply screwed therein.

The base B has a continuous horizontal diaphragm, a, which divides the base into two chambers, the upper being connected with the steam-inlet pipe, and the lower with the exhaust, as shown.

The diaphragm a is perforated under each of the pipes A, and the edge of each perforation is surrounded by the vertical rising flange b. Smaller than these perforations in diameter are the interiorpipes 0, open at both ends, above, extending inside pipes A nearly to their tops, and below through the perforations in diaphragm a into exhaust-chamber of base 13. They are provided with the inverted cups 0, which are larger in diameter than the flanges b, and extend below the top edges of same. They are supported at that point by small legs; or the cups may extend to the diaphragm, and have portions cut away. The result is the same; but they must be supported in such a manner that an open passage is left between alh N 0 further fastening .or support is needed.

This construction leaves a clear space between the pipes O, cups 0, and flanges b, to

form a water-Way when the water of condensation accumulates to an excessive amount, and

to form, with the water, a steam-trap between the two chambers of the base.

The operation is as follows: Steam being admitted at the inlet-pipe into upper chamber of base B, it condenses into water rapidly until the apparatus is warmed. By that time enough water will have formed on top of dia phragm a to lute the open spaces between 0, during which action the pipes A can absorb the heat from the live steam before it gets out of reach. The circulation is thus forced by the traps, and the hot steam must give its full benefit to the radiating-pipes.

Another advantage of my construction is, that in the possible forming of the water into ice no harm can arise by its formation, for, since the pipes (J are loose at both ends, should ice form it will push them up slightly. When the ice melts they will resume their normal position.

Having fully described my invention, what Iclaim, and desire to secure by Letters Patent, 1S-

1. In a radiator or heater of the class described, the water-luted steam-traps, consisting substantially of the flanges b and cups 0 In testimony that I claim the foregoing I around the openings'between the chambers, have hereunto set my hand this 7th day of substantially as shown and specified. December, 1875.

2. In combination with the pipes A of a radiator, the interior pipes (J, open at both ends, Witnesses:

and adjustable therein, substantially as de- GEO. M. JONES,

scribed, so as to be free to move, as speeified.- THos. J. MGTIGHE.
