JOHN CHAPMAN AND ROBERT'BRASS, OF BROOKLYN, NEW YORK.

STEAM-RADIATOR.

SPECIFICATION forming part of LettersPatent No. 258,374, dated May 23, 1882. Application lcd December 17, 1881. (No model.)

To all whom it may concern:

Be it known that we, JOHN CHAPMAN and ROBERT BRASS, citizens of the United States, residing at Brooklyn, in the county ot' Kings and State of New York, have invented certain new and useful Improvements in Steam-Radiators; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to certain new and useful improvements in steam-radiators. It has for its objects to effect a more perfect circulation ofthe steam with consequent greater radiation, and thefurther object of the perfect discharge of air and products of condensation, so as to prevent the annoyance ot' the usual thumping or hammering noise. l

Our inventionalso has for its objects to simplit'y the details of construction, as will b'e hereinafter set forth. t

Our invention consists in the particular construction and arrangement ot' parts hereinafter described and specifically claimed.

In the drawings, Figure l is a central vertical section of a steam-radiator embracing the features of our invention. Fig. 2 is a transverse section taken on the line .r rv, Fig. 1. Fig. 3 is a top view with the cap of the upper receptacle removed. Fig. 4 is a Vtop view with the cap in place, and Fig. 5 is an end view of the upper receptacle.

Similar letters indicate like parts iu the sev eral figures.

a is a steatntight inlet-pipe connected to the upper steamreceptacle, b, within which is ar,- ranged centrally a horizontal steam-conduit pipe, c, provided with a series ot' exit-holes along its bottom, as clearly shown at Fig. l.

f are the vertical pipes connecting the upper receptacle, b, and thelower receptacle, g. These pipes are screwed into the top of the lower receptacle, g, and are provided at their upper ends with nipples d, which are secured thereto by a screw-thread. The upper ends of the nipples pass through the bottom plate of the upper steam-receptacle, b, and are secured thereto by screw-nuts d. The nipples d have a central vertical orifice, t', for the passage of the steam from the receptacle b into the pipes f, and thence to thelower receptacle,.g. 4A suitable Washer is used, either between the shoulder of the nipple d and the under side of the bottom plate of the receptacle b or between the nut d and said plate, to make a steam-tight joint. The nipples d and `nuts d necessarily project above the bottom plate of the receptacle b, and any products ofcondensation existing in said cylinder are therefore prevented from entering any ofthe tubesf except those two at the endnearest to the exit h in the 'bottom receptacle, g, and designated by letter f and in order that the produetsof condensation shall enter and be discharged through such two end pipes we form in one end ot' the receptacle b a downward projection to form a transverse trough, e, so that `the nipples and nuts connecting the two pipesfat such point shall lie within or below the plane of the bottom of the remainderofthe receptacle b, whereby all waters from condensation gravitate to the trough c and nd their escape through the pipes at such point, and out ofthe exit-pipe h in the end ot' the lower receptacle, g, the bottom of which, to facilitate such exit, iuclines, as clearly-seen in Fig. 1, to said exit h. The top receptacle is made in two parts, and they are secured together by screw-bolts and nuts, as clearly shown at Figs. et and 5.

From the construction shown and described it will be seen that the steam enters .at ct into` the pipe c, escaping into the ltop receptacle, b, which is heated by the radiated heat from pipe c, and also by direct heat of the escaping steam. All condensation gravitates through the openings in the bottom of pipe c down onto the bottom plate ofthe receptacle into the trough e, and thence through the two end pipes into the bottom receptacle, and is discharged at h, while the dry steam circulates through the balance ot' the pipes f betweenthe upper and lower steam-receptacles, bg.

What we claim as new, and desire to secure by Letters Patent, is-

l. The top receptacle, b, and lower receptacle, g, connected by circulating-pipesf, secured within the bottom plate ofthe upper receptacle by nipples d, attached to the'ends of the pipes by screw-threads, said nipples passing loosely through the bottom plate of the receptacle verse trough, e, below the bottom ofthe recepand secured in place by nuts d', whereby the tacle to receive the products of condensa-tion, joiutmay bepacked,substuutiully asdescribcd. in combination with the end pipes,f, and nip- 2.
