To all whom it may concern."

Be itknown that I, CLARENQE.E.

Form, a citizen: of the UnitedStates, and a resident of Detroit, in the" county of Wayne.

This invention relates to radiators con- .structed of pressed sheet metal parts, and particularly to the means for controlling the flow of the heating fluids through the ra i-" ators; and its object is, to provide 'sim 1e and effective means for causing'the heating medium to flow through either or both of a plurality of groups of sections at will.

This invention consists in combination with pressed sheet-metal radiator-sections, of novel means whereby the whole or predetermined portions of radiators may be rendered operative. p

In the accompanying drawings Figure 1 is an end elevation of a radiator. Fig. 2 is a front elevation of the same, portions being broken away to show the interior construction. Fig. 3 is a horizontal section of a manually operable controlling valve that may be located near the upper portion of. the

radiator as shown in Fig. 2. Fig.4 is a .sec-

tion of the same on the line f-f ofFig. 3. Fig. 5 is a horizontal section of this valve onthe line gg of Fig. 4. Fig. 6 is a side.

elevation of the same. Fig. '7 is a section on the line hh of'Fig.'8 of the automatic control valve at the bottom of the radiator.

Fig.3 is a section on'the line of Fig. 7.

of the connection between the different portions of a radiator when arrangedfor onepipe steam service. .Flg. 9 1s a slmllar section when arranged for. two-pipe steam service. Fig. 10 is a View of a check valve of a radiator, so that, when the halves ofa sect on are assembled, water or steam chambers are, formed, consisting of three vertical columns 5 and 6. connectlng at then upper and lower ends by transverse chambers. At the upper and lower transversechambers of the sections are openings surrounded by substantially cylindrical flanges.

' It is often desirable to usela portion only of a radiator. In Fig.2 a radiator-construe tron is illustrated consisting of nine sections,which are separated in two groups of. three and six sections respectively. The means which are provided to control the flow of water 'orsteam to either or both of these sections are shown in Figs. 3 to ii inclusive. The main supply pipe 30 connects to any source and unites to the upright pipe 31, as shown in Fig. 2, which, in turn, connects to the valve body 321by any desired means, a union 33 being shown in Figs. 4 and 6. This body has a thpering bore and in it is revoluble a hollow' plug 34, open at the bottom, and provided with a reduced neck 35 which receives the screw36 that bears on the washer 37. The body 32 has an extension 38 divided by a wall 39. Hubs 40 on this extension 38 form tight joints with the flanges 9 on the adjacent radiator sections and stirrups 41 receive the ends. of the bolts 24, which secure the sections together. The body 32 is provided with ports 42, while the plug 34 has ports 43. When steam or hotwater rises in-the pipe 31, it may pass out- 5 through one of the ports 43 and through the adjacent port 42 and flow either to the right.

' the teeth 49 on the upper end of the body 32/ These teeth are in three pairs, so that the plug 34 may be positioned with, either 10 one,:both or none, of its ports registering I with the ports 42 of the body 32. A-handle 50 is pivoted in the outer end of the arm position indicated in Fig. 5, an angular distance equalto that between the centers of H adjacent teeth. The finger 48 will then be permittedto rest between the second and third teeth 49 on the body 32, counting the teeth from the nearer end of the-row. The resultof such movement of the handle 50' is the turning of the valve-plug 34 to 'a position where neither of its ports 43 reg The body 52 of this check-valve has an unobstructed passage between the pipes and 81 to permit the heating fluid to pass freely to the control valve. A. partition wall 53 extends from a cross wall 54 to the rear of the body, and hubs 55 formed on the body form tight joints with the flanges 9 of the adj acent' sheet-metal sections. Stirrups 56 extend from these hubs and receive the ends of the locking bolts 24. A plug 57 screws into the front wall-of this body and may be removed to permit the introduction of a stop-plate or a valve-seat.

When this radiator forms part of a sin gle-pipe steam heating-system, a plate 58 (Fig. 8) is mounted in the body, and pro vided with openings .59. mounted on the pin 62 (Fig. 10) and nor mally cover these openings and prevent steam entering the lower portion of the radiator. But when the steam condenses in the radiator and water fills the-lower part of either portion thereof, the weight of the water will swing out the proper valve and permit that portion of the into the pipe 30.

Where the radiator formspart or a two.-- pipe steam heating-system, the plug 64 of".

Fig. 8 is removed, and a plate 65,; similar to the plate 58, is positioned, as shown in 9. The valves 66 have counterweights 6 to The p "ate 58 and its valves are removed and a plain plate 68 substituted.- And a pipe 69 is connected to the check-valvebody 52,

- as shown in Fig. 9, the fitting 70 and union '72 being employed if desire It will be evident that the main supply pipe may extend at any angle to and any distance from the radiator, and that the" connections shown in Figs. 3 to 11- to the radiator may be proportioned accordingly;

The supply pipe may be entirely independ ent of the discharge pipe and the fitting 52 can be easil chan ed to meet such demand.

The steam will flow up the pipe 31 and be distributed by means of the control valve as before stated, and will enter the checkvalve body through the hubs 56 and then avoided, as the swinging brackets Valves 60 are radiator-to drain reventthe returnflow of the steam.

iseases pass down through the openings 73 in the plate to the pipe 69.

When the radiator is tojbe used in a hot-- water heating-system, the plate 65 and I valves 66 are entirely omitted, thus permitting the water to flow unrestricted to the source of supply. ,The radiator will be entirely controlled by the valve ofFig. 4.

As these radiators willbe'very light, they may be supported by means of brackets such as shown in Fig. 1. The lower bracket 7 5 is shown pivoted on a plate 76 attached to the base-board 77, while the upper bracket is shown formed-of two pieces 78 and 79 adjustable with reference to each other. The inner portion 78 is also pivoted to a plate 80, attachedto the wall 81. By pivoting these brackets, all-strains caused by the expansion of the radiator sections and of the feed and return pipes, are

free expansion in all directions.

Because, of the nuts on the-ends of the rods 24 on the outside of. the closures 25, the stress or pull of these tie-rods can be predetermined. To extend aradiator already in place, the caps 26, closures 25 and nuts 27- at one end are removed and, extensions connected to the tie-rods. The additional sections are then-positioned and'drawn into place by the nutsf27 on these extensions. llt is therefore desirable to form the tie -rods 24 and nuts 27 with standard pipe threads so that such additions may be made by isteam fitter.

ltwill be understood that these radiators may be employed in connection with cooling systems and that theword' heating is not to be taken as "limiting the scope of the claims wherein it is used. lhe. esigns of permit the sections and the proportions of theparts,

the thicknessof the metal and the material employed, may'allbe varied by heating engineers to suit the. difierent requirements, without departing-from the spirit of my inventionas set'forthinthe claims. lclaim' p L A radiator comprising a series of sec tions connected into two groups, asupply pipe for the radiator, a valve body at the upper end of the pipe and having discharge hubs connecting to the upper ends of said sections and adividing plate between said hubs, a "valve-phi mounted within the body and provided wit 'portsto permit the heating. element to pass from {said pipe 'into saidbody on either side or both sides of said plate at will, means to position said valvel'la pluga'nd, an outlet fitting connecting the lower ends of the groups.
