VLLIAM H. BROOKS, OF WEST POINT, NEV YORK.

STEAM-RADIATOR.

SPECIFICATION forming part of Letters Patent No. 291,026, dated January K1, 1884.

` Appiicnfiontledimy 7,1883. (No model.)

'.To a/ZZ whom t may concern:

Be it known that I, WILLIAM H. BRooKs,

Y of West Point, county of Orange, and State of l adapted for the reception of steam at high or .low pressureor any other heatconducting fluids or liquids. The several improvements hereinafter specified may, however, be employed advantageously in radiators ofthe class l'rnownas indirect radiators, or those which are located in an air-conducting flue at a distance from the space to be heated.

The objects of my invention are, primarily,

to lproduce a simple, cheap, and durable radi- .ator wherein the heat-conducting fluid shall be suitably subdivided within the structure, causing a positive circulation through the several tubes thereof, and exposing alarge heating-surface of metal to the space to be 'warmed, and to so arrange and construct the 3o base and the tubes that both may be made of cast metal, bereadily united for use or disunited for repairs, and the structure be auto- ;matically drained of condensed steam Without 3 interfering with the heat-producing qualities of the apparatus.

vTo accomplishall of this,

my improvements involve certain novel and useful peculiarities of constructiomrelative arrangements, or combinations 'of parts and details of manufacture, all of which will be herey free and open.

[through lines y y and .e c, respectively, of

Fig. 5. Fig. 5 is an elevation of the cluster shown in Fig. 1, the same Abeing detached from the base. Fig. 6 is an elevation of a cluster, detached from any base, the same being made in all respects like that of Fig. l, except that instead of four small tubes' only two are required to form the cluster; and Fig. 7 is a plan ofthe bottom of the cluster shown in Fig. 6.

In all the figures like letters of reference. wherever they occur; indicate corresponding parts.

A is the base-piece of the radiator. 1 This is 'made of cast-iron, intended to rest upon the Afloor, and to support the radiating -tubes above it, ,beingk for that ,purpose provided with a series of .screw-threaded openings calculated to receive the correspondingly-threaded 'ends of the tubes. y

The drawings represent the base as made to receive only two lines o1' the radiating-tubes, but, obviously, the width of the base may be increased, and as many lines or rows of tubes be employed as may be required, the baselbeing properly fashioned to receive them. The length of the base is not limited, nor its outline, which may be square, rectangular, or circular.

Within the base, and preferably cast therewith, are the dividing-strips d d, extending under all the threaded openings, and below each strip is a pocket, e, into which the water or condensed steam settles and closes the communication between the spaces on opposite sides of the strips, which otherwisewould be The radiating-tubes are also made of cast-iron, each main tube being composed of a number of smaller tubes, the openings through which are united at top" and bottom, affording ample room for the passage of steam and affording an extended areaof exterior surface (between ,thetop andbottom) which is exposed to the air, the latter lbeing free vto circulate Abetween fthe several small tubes.

.These small tubes in each 'cluster are arrangedin pairs, as ab, c b, Iftherebe more than four, then they also' vare arranged in pairs.

In the base of the cluster is the dividingstrip c, calculated to rest upon the strip d as soon as the pipe is turned into its seat to a IOO proper degree, this base being provided with a thread or winding suitable for the purpose.

Each of the small tubes in the cluster has a free open way through its base, as plainly indicated in the Figs. l and 2, the openings from tubes a being on one side of the strip c, and those of tubes Z1 being on the opposite side.

At their upper ends these tubes all unite in a common chamber, as indicated in Figs. l and io 3. The clusterso formed and arranged is cast in a single piece, using the sand core as usual. There then remains only the base part of the cluster to be fitted to enter the seat provided for it; and, this being circular work, may be quickly and cheaply accomplished.

The division-strips d being located, as explained, under each row of tubes, there is an inlet side and an outlet side for each one employed in the make-up of the apparatus. Vith two rows,we have the inlet-port, as at y, and the outlet or exit, as at 71., in the base A. Steam entering at q takes the course shown by the arrows, ascends tubes a in each cluster and descends through b, and passes tothe outlet h through the several rows. Thus we have a perfect circulation through the radiator. The pressure of the steam on the water in trap c is equal on both sides ofthe dividing-strip d, so that the water in the trap will not be disturbed, but by its presence will compel the circulation in themannerindicated. "W hen too much water collects in the base A, it is automatically' drained through the outlet h.

The outlet and inlet ports are represented as being located on the ends of the radiator. They might be arranged at any points of the sides, if desired-one on 011e side and one on the other-or both on one end, it being only necessary that they fall on opposite sides of the divisions into which the base is separated. This makes it very convenient to locate the radiator and to carry the conduit to and from it in any desired direction.

The clusters of tubes at top and bottom are blended into one, so that they are in et'ect, when being handled,the same as a single tube 5 but they possess a much greater surface for contact with the air ot' the room, and, moreover, they compel (with the adjuncts named) a complete circulation through them of the heating-Huid, and do not depend upon mere expansion, as in the single-tube expansionradiators heretofore mainly constructed.

In the circulation-radiators of former constructions, the base of the device has been divided into an inlet and outlet chamber; but the tubes, being separate, are with difficulty assembled and with great difficulty dismounted, especially when an interior tube has been rc- 6o quired to be removed In the latter case it echoes is necessary to rst remove the exterior rows of' tubes in order to gain access to those of the interior rows.

Vith my improved form of circulatingtube, any one tube in the radiatory may be quickly detached by unturning it without disturbing any of the adjacent tubes; and, if desired, its threaded seat may be plugged up and the remainder of the radiator operated the same as if all the tubes were in place.

W'hen constructed and arranged for operation substantially in accordance with the foregoing explanations, the improved device will be found to admirably answer the purposes or objectsof thcinvention as previously set forth.

It is not essential that the small tubes a ar b b be made circular in cross-section, as indicated. They may be of any form which is convenient to east, and they may be assembled in the clusters in any way to produce any required outline.

.Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, ism

1. In combination with the radiator-base, one or more division-plates ruiming the entire length of said base and located beneath the centers of the tube-holes, and the traps or depressions in the base beneath the divisionplates arranged to close the openings between the several compartments at the lower margins of said division-plates, substantially as shown and described. and for the purposes set forth.

2. In a .radiator-base, the division-plates running the entire length thereof, located beneath the centers of the tubeholes, and the traps or depressions below said divisionplates arranged to close the communication between the several compartments of the base, except through the medium of the superposed circulating-tubes, all combined and arranged substantially as and for the purposes set forth.

3. In asteam-radiator of the character herein set forth, the combination, with the base having the division-plates extending beneath the centers of the tube-holes, of the herein described clusters of radiator-tubes arranged in pairs cast in a single piece with their crossstrps, and the traps or depressions beneath the plates in the base, all arranged to compel a circulation through the tubes, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand in the presence of two witnesses.

IVILLIAM H. BROOKS.
