STEAM-RADlATO R.

SPECIFICATION forming part of Letters Patent No. 295,343, dated March 18, 1834. Appia-mon met June s, ms. No model.)

To @ZZ whom t may concern.-

Be it known that we, ROBERT BRASS and JOHN CHAPMAN, Aboth of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Steam-Radiators, of which the following is a specification.

This invention has reference to improvements in that class of steam-radiators which are made entirclyfof cast-iron, and in which the steam enters at the top of the radiator,

while the water of condensation is coilected and and of a bottom chamber having an inclined.

bottom, the top and bottom chambers having interior side and center lugs, to which the flanges of the middle portion are secured byv screw-bolts.

In the accompanying drawings, Figure 1 represents a vertical longitudinal section on line a: as, Fig. 3, of our improved steam-radiator. Fig. 2 is a vertical transverse section of the same on line?,l y, Fig. l. Fig. 3 is a horizontal section on linezz, Fig. l; Fig. it, a plan of the bottom chamber, shown as detached; and Fig. 5 is a horizontal section of the top chamber on line c c, Fig. l.

Similar letters of reference indicate corresponding parts.

Ain the drawings represents a cast-iron top chamber, which is provided with 'longitudinal bottom openings, c a., and at one 'end with a steam-inlet pipe, a. Aperforated ornamental top plate, A', is placed on the top of the chainber A, so as to prevent contact with the heated surface of the same.

B is a bottom chamber, which is also made of cast-iron, and provided with longitudinal top openings, Zn b, an inclined bottom, 11', and a discharge-pipe, be, for the water of condensation, at the lowermost part of the bottom b. The top chamber, A, is connected with the bottom chamber, B, by one or more intermediate castings, G, each of which consists of a row of circulating-pipes, d d, which are made of starshaped or other suitable cross-section, so that a large radiating-surface is obtained. Each row of pipes C is provided at the upper and lower ends with iianges d' d2, respectively, which are cast integral with the body of the circulating-pipesC, so as to serve as a direct means of connection between the top and bottom chambers. The contact-faces of the iianges d d'2 of the intermediate casting, C, as well as the adjoining faces of the top and bottoni chambers, A and B, are planed or smoothly ground oft', whereby they iit exactly to each other, th ey being furthermore packed by an intermediate layer of lead or other suitabie packing, so as to prevent the escape of steam. The danges d d2 of the circulating-pipes d d are secured to the face-plates of the top and bottom chambers by screw-bolts (Z3. For this purpose the top and bottom chambers are provided with interior projecting lugs, e e, cast integral with the chambers at the side walls of the same. Screwholes are drilled through the face-plates of said chambers and into the lugs c, but not entirely through the same, but of sufficient depth, so that the screw-bolts can firmly take hold of the same. The auges d d2' are perforated for the passage of the fastening-bolts. Then the radiator is to be constructed with more than one row of circulating-pipes, the top and bottom chambers are further cast with centerlugs, e' e', extending transversely between the longitudinal openings c a and Z1 I) of said chambers. These lugs serve also to strengthen the faceplates of the chambers A and B, as they have to be made wider when several rows of circulating-pipes are to be used. Through the lugs c and top and bottom plates of the chambers Aand B are drilled holes-one at each end ofthe lugs-also corresponding holes in the flanges d di. rlhe top chamber,A, is first connected to the intermediate castings, C C, by being placed ininverted position. The castings Care placed thereon, and the screw-bolts e e then dropped, with their threadedshanlrs downward, through the holes of the iianges and center lugs, and then screwed tight by nuts e. The bottom chamber, B, is then connected in the same manner with the castings O, which are placed in upright position on the bottom chamber. The screw-bolts of the side lugs are next screwed in, and thus a rigid connection of the main parts of the radiator obtained, in which all the screw-bolts engage solid portions of the chain- IOO bers Without giving exit to the steam, so that leakage resulting from untightness of the parts is entirely obviated. As the main parts composing the radiator are made of cast-iron, a radiator of cheap construction that emits the heat quickly and effectively is obtained.

Having thus described our invention, we claim as new and desire to secure by Letters Patentl. Asteam-radiator composed of atop chamber having bottom openings, an intermediate casting or castings, each composed of a row of circulatingpipes having top and bottom flanges east integral therewith, a bottom chamber having openings at the upper part, and means whereby the top and bottom chambers are connected to the flanges of the intermediate casting or castings, substantially as and for the purpose set forth.

2. The combination, in a steam-radiator, of the top andbottom chambers, A and B, having openings a a and b b, and interior projecting lugs, e e, cast integral with said chambers, an intermediate casting, C, composed of a row of circulating-pipes, d d, and top and bottom flanges, d d2, cast integral therewith, said top and bottom chambers being connected to the -llanges of the intermediate circulating-pipes by screw-bolts that take into the interior` lugs of the chambers, substantially as set forth.

3. The combination of top and bottom chambers, A and B, having openings a a and b b, and interior side and center lugs, e3 e', intermediate castings, C C, each composed of a row of circulating-pipes, d d, and of top and bottom flanges, d d2, and screwbolts et and e, that connect the flanges of the castings with the lugs of the top and bottom chambers, substantial] y as set forth.

4. Ina steam-radiator, the combination of the top and bottom chambers, A and B, having longitudinal openings, interior andApartly-perforated side lugs cast integral With the Walls of the chambers, and the intermediate castings, C C, each composed of a row of pipes having top and bottom flanges, substantially as described.

5. In a steam-radiator, the top and bottom chambers, A B, having openings a c and b b, interior and partly-perforated side lugs and perforated center lugs, said side and center lugs being cast integral with the body of said chambers, substantially as described.

6. In a steam-radiator, the combination of the top chamber,A,provided with longitudinal openings in its bottom, the steam-inlet pipe a', lugs c c3, partly-perforatedzcastings C C, nuts c2, the top plate, A, and the bottom chamber, B, provided With lugs c c3 and dischargingpipe.

In testimony that We claim the foregoing as our invention We have signed our names in presence of two subscribing Witnesses.
