To all whom it may concern:

Be it known that I, EMILE Josnrn PEGLER, a citizen ofthe United States of Annerica, and aresident of theborongh of Manhattan, in the city, county, and State of ew; York, have'invented certain new and useful Improvements in lV-ater-Circulating Radiators, of which the following is a specification,'1'eference being had to the accompanying drawings.

This inventionrelates to improvements in radiators and particularly to improvements in hot-water radiators; and an object of this invention is to provide a hot-water radiator which will contain within itself its own water-heating means and will therefore dispensewjith the necessity Oftheinstallation and maintenance of a boilerplant and of expensive pipe connections therefrom to the radiator and from the latter to radiators in other rooms of the building.

Another object of this invention is to provide a radiator which will in its operation be free from steam pressureand which can be manufactured of comparatively,thin: metal and therefore economically, which will radiate a largerproportion of the heat supplied than would a ,radiator made of heavy material.

I A third object of this invention is to provide a hot-water radlator which will fur- 111Sl1 heat for the sa ne fuel consumption as is now required by largeheating plants and which will require no larger heat-radiating surface than is needed by an ordinary steam-radiator.

A furtherobject of this invention is to provide a radiator which will serve to in air, vitiated by the burning of oil or gas, be ng led entirely lnto the open alr, whereby. there s attained a sanitary advantage which has'been sought for but never obtainedbefore. Bv neans of the radiator hereinafter described, there is solved the problem of saving the cost of expensive steam-heating plants and, at the same time, there are more- I over provided radiators which giiefiqual,

comfort and are more sanitary in their oper-I ation and are within the reachof thepurse of the rich and poor alike. The essential feature whlch lies at the basis of the radiatQl 'f-fmlnlng he Bil- 3W? of. this inv -i9 as and the great velocity with, which the water circulatesin the radiator-despite the small amount of fuel consumed.

This invent on cons sts of the constructioin arrangement and combination of parts designed to: produce a radiator made up principally of t'ubular annular or ring-like metal sections that are heated by means and in 'a manner, designed to preventthe vitia tion of the air and to secure at the same time a rapid circulation ofthe water in all parts of the diatoi' section.

The way in whichthe foregoing objects are attained in the most practical and simple manner is described 'hereinafter wit-h reference to the accompanying drawings, in which similar characters denote correspondingpartsf throughout the several views and in which;

'In .Fig. .1 there is illustrated in front elev o mister, ,diatqr ivhi lls mp l es a series of spaced ring-like, annular or O- shaped metal tubes, which may have a cir cular, elliptical, square or other suitable cross-section. Each of these sections includes two vertical legs 0, connected at their upper ends by a substantially semicircular curved portion At the lower end of the leg 0 there is formed a semicircular-prolongation or extension 0 h'av ing substantially the same curvature as the upper curved part 0. These rink-like sec tions are arranged in a row and are spaced apart and give to the radiator its width. Near the bottom of the radiator, there is arranged a horizontally-(iisposed shallow water-container N, which runs widthwise from end to end throughout the whole width of the radiator. The inner side of the 'column O communicates with one side of the water-container N; the connected portions of both being cut away. Extending horizontally within the water-container there is a burner-casing A which is surrounded by the water held in the water-container N. Into one end of this casing A there projects a fuel-pipe B and the inner end of the latter is in the form of a burner B From the other end of the casing A there leads an exhaust-pipe G which is designed to carry off the waste products of combustion. The burner B may be suitable for the burning of liquid or gaseous fuel, for example. In one of its side faces (not visible in Fig. 1), the shell of the water-container N is formed with an opening that is closed by a small door F (Fig. 1 in which there is arranged a ventilator V in the form of a small exhaust-fan of the approved type commonly used in the windows of stores, shops and the like. The door F closes a watertight air-passage P which leads from the ventilator V to the interior of the easing A surrounding the burner-chamber; and, through this passage P, there flows the air which supports the combustion within the burner-chamber. The small exhaustfan V prevents the air from flowing backwardly through the passage 1 The heated water flows upwardly from the water-container N into the legs 0 of the several sections and changes its direction of flow in passing through the curved portion 0 and thereafter flows by gravity downwardly through the other leg 0 and enters the water-container again through the curved lower portion 0 Above the sections and extending widthwise thereof, there is mounted a metal box H which is designed to receive the water which, by reason of the expansion thereof, enters the metal box H through the small pipes K. In the top of the metal box H, there is provided a door J, through the opening closed by which there may be poured water, when it is desired to replenish the supply of water in the radiator see-- tions. Of course, the door J is normally kept closed.

In Fig. l there is illustrated in detail the lower part of a radiator section, the tubu lar legs of which are elliptical in cross-sec tion and communicate with the water-container N In this case, there is an individual or separate water-container N for each section. The burner-casing A and burner B extend horizontally through the several water-containers N By this provision of a separate or individual watercontainer for each section, it results that there is no superfluous quantity of water heated.

The radiator shown in Fig. 2 is made up of a single ring-like or annular section consisting of an outer shell 0, O, O O and an inner shell I separated from the outer shell by an interval of about two inches. The inner and outer shells are connected and the space between them is closed by the end walls E. In the top of the outer shell there are formed two openings K, K which are normally closed by screw-caps. The water space may be filled by water poured through one of the openings, the other hole then serving to permit the escape of air. Near the bottom of the leg 0 of the water space, there is arranged a horizontally-extending burnercasing A, into one end of which there extends a fuel-pipe B and from the other end of which there leads an exhaust-pipe C to carry away the waste products of combustion. At N opposite the burner-casing A, the inner shell I projects inwardly so as to afford suflicient space for the circulation of the water around the casing A. The fuelpipe B terminates within the burner-casing A in a suitable burner. That end of the burner-casin A which is opposite from the exhaust pipe C projects from the end wall E, to be covered with round cap F used as a door for lighting. Fuel supply pipe B goes through the center of the cap F as an axis. The cover or top of said cap F is a small revolving fan V, of any approved type as described in connection with Fig. 1. On the drawing of Fig. :2 this cap is shown removed for better illustration. The heated water rises, as before, in the upright portion 01' water leg 0, changes direction at the top falls by gravity through the other water leg 0 and returns through the curved part 0 An expansion chamber (such as the chamber H of Fig. 1) may be dispensed with by putting a mark H on the radiator to indi cate the proper level of the water when the radiator is cold. A water gage is unnecessary; for, the level of the water can be ascertained by tapping or touching the thin metal shell with the hand.

Fig. 8 illustrates in front elevation a hotwater radiator comprising a series of ringlike sections which are made of drawn metal tubing and are connected one to the other so that the hot water will travel continuously from one section to another throughout the whole system. Each section has an upright or substantially vertical leg 0 whichis connected at its'top by a semi-circular part 0 to the other leg 0 which is inclined slightly and is joined'to the vertical leg 0 of the next succeeding or adjacent section'by the curved part Thetop of the last leg 0 is connected, by a horizontal tubular portion H with the top of the first inclined leg 0, so thatthe water flows in a closed circuit from one section to the other, as is indicated by the arrows in Figs. 3, 3. The horizontal connecting partI-I. is placed above the sec tions, instead of below the same, so that this part H may be provided with a door J through'the opening closed by which the supply of water may be replenished; but it would be perfectly feasible to place the connecting part H below the sections, in which case the water would flow through this part in the opposite direction. 'The water in the several sections of the radiator is, as could be the case of the other forms of radiatorherein described, heated by an electricconductor through the sections B of which flows the electric current. There is a sectionB of the electric conductor mounted in the lower part of each ofthe several substantially vertical water-legs O.

In Fig. 4. there is illustrated a round hot waterradiator comprising a series of ringlike radiator-sections made of stamped or drawn-metal tubing and arranged around a centrally-disposed vertical burner-casing A which is closed, at the level of the upper ends of the legs 0, by the circular plate W and into the lower end of which there projects a burner of any suitable type (not shown): and, from the upper end of the burner-casing A, there leads, through an opening in the plate V, an exhaust-pipe C which carries oil" the waste products of combustion. By this arrangement, the several legs 0 are exposed to the heat from the common burner casing A. Above the radiator there is arranged a water-drum H which serves as an expansion chamber, this drum being connected by pipes K with each of the several sections. A door J in the drum H closes an opening through which the water supply may be replenished. At its center the drum H has a watertight passage through which extends the outlet pipe C. The drum H is shown round but it may be of any other suitableform; for example, it might be of an octagonal shape similar to that of the skeleton frame or spider X which is supported by the radiator legs Y and which supports the radiator-sections.

The burner-casing A may be left open at its lower end, through which the cold air enters supp rt the com tion; and the heated waste products of combustion will rise and flow away through the exhaust pipe C and cannot accumulate in the room tobe heated. The water is heated simultaneously in each of the inner legs 0 of the several sections, changes its direction at the parts 0 falls by gravity through the outer legs 0 and rapidly returns to the legs 0 through the curved lower parts 0 Fig. 5 represents a round hot water radiator, similar to that shown in Fig. i, comprising a series of ringlike radiator sections made of stamped or drawn metal tubing, and assembled around a centrally disposed vertical burner casing A which is closed at the level of the upper ends of the legs 0, by the circular plate 'VV; and in the lower end of which there is a round burner B located, of any suitable type, with an opening F "at its center as fresh air intake. Said burner is surrounded by the water container N which container substitutes the inner half of the bottom curve 0 of each section, these being cut away, like in Fig. 1. Said water-container N feeds simultaneously the columns O of each section, and receives back the unheated water from O similarly as in Figs. 1 and 2. Plate W is connected at its center with exhaust pipe C which carries off the waste products of combustion. For filling the sections with water a round drum can be used, as described and shown in connection with Fig. 4; to receive the said drum there are flanged holes I at the top of each section. The burner 13 may be suitable for the consumption of liquid, gaseous or electric fuel. Letter X indicates the skeleton frame or spider which supports the radiator sections, and has legs marked Y. The water being heated simultaneously in each of the inner legs 0 of the several sections, changes its direction at the bend O falls by gravity through the outer legs 0 and rapidly returns through the curved lower part C) to the container N It is obvious that the combustion of a suitable fuel could be made to take place at a point lower than that shown in Figs. 1, 2 and 3; but the combustion must in any case take place at a point higher than the lowestpoint of the curved portion 0 in order that the water may be made to rise in one of the legs and flow down the other leg of the section, as hereinbefore explained.

Although the forms of radiator hereinbefore described and shown differ somewhat in appearance and arrangement of parts, yet the mode of operation of all the several forms is the same. In each of these forms, the water-column in the leg on the side on which the water-heating unit is arranged is caused to rise upwardly, while the watercolumn in the other leg of the section flows by gravity downwardly to take the place of th h ted wfuel -e l lunand ther y h re is produced automatically a constant circulation of the water; and therefore the radiator is called by me a water-circulating radiator.
