SPECIFICATION forming part of Letters Patent No. 789,231, dated May 9, 1905. A iicai'ofl fiiea April 1, 1904. 'Serial No. 201,049.

To (LZZ whom it may concern:

Be it known that I, JAMES E. PEoK, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Heaters, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description. I

This invention relates to improvements in heaters, and refers more particularly to a generator for producing low-pressure steam or hot-water circulation through a radiating system, although it may be employed as a combined hot-water and steam generator.

The primary object of this improved heater is to distribute the water circulation within the generator in such manner that the water in certain divisions of the interior heating system is more rapidly heated than in other parts of the system, so that the water or steam of the more rapidly heated division may be conducted separately to remote or distant and colder parts of the building, while other divisions of the heating system in which the water is heated less rapidly may be conducted to other less exposed parts of the building or to such rooms as are nearer the generator in order to maintain a uniform temperature throughout the building.

Another object is to utilize the space between the inner shell and outer jacket or casing for the purpose of heating air to be distributed to any part of the building in which warm air may be desired.

Other objects and uses will appear in the following description. In the drawings, Figure 1 is a front elevation, partly in section, of my improved heater, showing the inclosing shell for the combustion-chamber and the outer casing in section. Figs. 2 and 3 are sectional views taken, respectively, on lines 2 2and3 3, Fig. 1. Fig. 4 is an elevation of one of the divisions of the interior heating system of the generator, showing the smaller upright water-legs and their connection with the central upper distributinghead or drum, which division is employed for heating the remote or exposed parts of the building.

Similar reference characters indicate cor responding parts in all the views.

' In carrying out the objects stated I provide a suitable base having an ash-box 1, upon which 'is mounted a horizontally-disposed water-containing ring or hollow shell 2. This ring is comparatively shallow vertically and 0 forms the base of the fire-pot to receive the return-flow of water from the radiating system through suitable return-conduits 3, which in this instance enters the sides of the ring 2, as best seen in Figs. 1, 2, and 3. The ashbox 1 is provided with a suitable clean-out opening 4 and a grate 5, which is located in a plane just beneath the lower wall of the water-base 2. Mounted upon the upper wall of the water ring or base 2 and rising therefrom are two circular rows of upright waterlegs 6 and 7, which together form a continuation of the fire-box or combustion-chamber and communicate at their lower ends with the interior of the water base or ring 2 through suitable connecting- nipples 8 and 8, Figs. 1 and 4. The upright water-legs 6 are of considerable capacity or cross-sectional area, and

' their inner upright faces are disposed in vertical planes substantially coincident with the inner face or wall of the ring 2, while the other upright water-legs 7 are of comparative small capacity and diameter and are arranged between the larger sections 6, with their inner upright faces also disposed in vertical planes substantially coincident with the inner wall of the ring 2, so that the larger and smaller upright water-legs alternate with each other around the combustion-chamber.

The smaller upright water-legs 7 form a part of the circulating system separate from that of which the larger upright water-legs are a part, and it will be observed that owing to the proximity of the smaller water-legs 7 to the combustion-chamber and also to the comparatively small volume of water which each contains, as compared with the volume of water which is contained in the larger upright pipes 9 to a superimposed distributing head or drum 10, from which the heated water or steam is distributed to the remote or more exposed parts of the building through pipes or conduits 11.

The conduits 9 are superimposed above and are tapped into the upper ends of the smaller upright water-legs 7 and are extended laterally with one or more return-bends over the combustion-chamber and are then tapped into the lower wall of the distributing-head 10. These lateral extension or return bends of the conduits 9 serve two purposes: first, it brings the upflowing water or steam directly in the path of the products of combustion, whereby the water or steam is further heated, and, secondly, these return-bends permit the free contraction and expansion of the upright waterlegs and also the conduits 9 without liability of unduly straining the joints, thus reducing the liability of leakage to a minimum. In like manner the upper ends of the upright water-legs 6 are connected by pipes or conduits 12 to superimposed distributing-heads 13, in this instance two in number, which are located at opposite sides of the distributinghead 10 and parallel therewith, the head 10 being arranged substantially centrally over the com bustion-chamberfrom front to rear of the generator, while the heads 13 are substantially the same size and length as the head 10 and equidistant therefrom.

The intermediate portions of the conduits 12, which rise from the water-legs 6 at one side of the center of the heater, are provided with onevor more return-bends which extend laterally over the combustion -chamber and discharge into the superimposed distributinghead 13 at the same side of the generator from which the conduits start.

It is now seen that substantially half of the larger water-legs 6 at one side of a center line drawn through the generator from front to rear, together with their conduits 12 and one distributing-head 13, connected thereto, constitute a separate circulating system from the similar water-legs 6, head 13, and conduits 12 at the opposite side of the center line of the generator, so that practically three separate circulating systems are shown those connected to the distributing-head 13,

-constituting similar systems in which the heat and circulation are substantially the same, while the circulating system connected to the head 10 is more rapid in its action than the others. This rapidity of circulation and comparative excess of heat is due to the fact that the water-legs 7 are of much smaller capacity than the water-legs 6 and also from the fact that the distributing head is located centrally over the combustion-chamber, and the coils of the conduits 9 are nearer the source of heat, between the coils of the conduits 12 and upper ends of the upright water-legs. These several upright water- legs 6 and 7, as well as similar pipes 16 from the heads 13 are extended.

The construction thus far described constitutes the essential elements of my improved heater; but I preferably provide an outer casing 17 of suitable material, which rises from a supporting-base 18 beneath the ash-pit 1. This outer casing is. arranged so as to form an air-chamber 19, surrounding the ash-box 1, ring 2, and shell lt, and the upper end of the casing 17 is provided with a suitable dome 20, which is also arranged so as to form a dis tributing air-chamber 21 above the dome 15, which communicates with the air-space 19, said distributing-chamber 21 being provided with suitable outlets 22, to which pipes may be connected to convey the hot airto any desired locality.

A suitable air-inlet opening 23 is made in the lower portion of the side of the casing 17, so that the cold air entering the inlet 23 comes in contact with the heated walls of the interior mechanism and rises through the chamber 19 into the distributing-cham ber 21 This air-heating system is advantageous, but is not essential to the operation of the steam or water heating system and may be dispensed with, if desired.

At the front of the heater one of the larger upright water-legs 6 and the two adjacent smaller water-legs are omitted to permit the insertion of a fuel-inlet conduit or frame 25, which extends from the outer casing 17 to the combustion-chamber, said fuel-inlet conduit being disposed some distance above the waterring 2 with its upper wall substantially coincident with the upper ends of the water- legs 6 and 7, as shown by dotted lines in Fig. 1, so as to afford as deep a fire-box as practicable.

The space below the fuel-inlet frame is partially closed by the transverse coil of a pipe 26, having its lower end tapped into the upper wall of the water-ring 2 and its upper end connected to one of the distributing-heads, as the right-hand head, Fig. 1.

It is apparent from the foregoing description that the water which is fed into the water base or ring 2 rises in the water- legs 6 and 7 and is expanded by the heat, so as to flow upwardly through the conduits 9 and 12 into the distributing- heads 10 and 13, from which it is carried by the conduits 11 and 16 to the radiators, (not shown,) and is returned from said radiators in the usual manner to their respective inlets 3 in the base of the ring 2. It is also apparent that the water in the smaller water-legs 7 is heated much more rapidly than in the water-legs 6, and therefore the circulation from the distributing-head 10, which is connected to the smaller water-legs,

is more rapid and the heat in this part of the system is greater than that through the systems of which the heads 13 are a part. In fact it is possible and practicable under this system of heating to supply steam from the head 10 to one series of radiators while the remaining parts of the system supply hot water to other radiators of a building, and it is this particular distinction upon which I seek protection.

Having thus described my invention, what I desire to secure by Letters Patent, is

1. In a heater, the combination of a waterbase and upright water-legs forming a combustion-chamber, some of the water-legs being smaller than the others to heat the water more rapidly, a distributing-head connected to the smaller water-legs, and separate distributing-heads connected to a number of the larger water-legs.

2. In a heater, the combination of a waterbase, a circular row of water-legs of comparatively large capacity rising-from the base, conduits leading from the upper ends of said wa ter-legs, an additional circular row of waterlegs of comparatively small capacity rising from the water-base, and conduits leading from the upper ends of the smaller water-legs.

3. In a heater the combination of a waterbase, water-legs of comparatively large capacity rising from the base and communicating with its interior, and additional waterlegs of comparatively small capacity also rising from said base and communicating with its interior, said water-legs being arranged in circular rows and forming a combustion-chamber, the smaller legs alternating with the larger legs around the combustion-chamber, conduits leading from the upper ends of the water-legs and a distributing-head connected to the up per ends of the conduits which lead from the smaller water-legs.

i. In a heater the combination of a waterbase having return-inlets, upright water-legs rising from the water-base and communicating with its interior, said water-legs being arranged side by side and forming a combustion-chamber, the alternate water-legs being of diflerent capacity than the others, a distributing-head connected to the upper ends of the smaller water-legs, and additional heads connected to the upper ends of the larger water-legs.

5. In a heater, the combination with a combustion-chamber of a water-ring having a central circular opening forming a part of the combustion-chamber, two concentric rows of water-legs rising from and communicating with the interior of the ring and surrounding the combustion-chamber, those of one row being smaller than those of the other row to produce a more rapid circulation of water therein, conduits leading from the upper ends of the water-legs and extending laterally over the combustion-chamber and a distributinghead centrally over the chamber and connected to the conduits which lead from the smaller water-legs.

6. In a steam and hot-water heater, the combination with a combustion-chamber of a water-base having return flow openings, separate series of water-legs surrounding the combustion-chamber rising from the base, those of one series being smaller than those of the other series to cause a more rapid circulation and a higher temperature of the water in the smaller series, each leg having a separate conduit leading therefrom.

7. Inasteam and hot-water heater, the combination of a waterbase having return flow openings, separate series of water-legs rising from the base and forming a combustion-chamber, the water-legs of one series being smaller than and alternating with those of the other series, and separate distributing heads connected to their respective series of water-legs for the purpose described.

8. In asteam and hot-water heater, the combination of a Water ring, and separate series of upright water-legs rising from the ring and forming the inclosing sides of a combustion-chamber, each water-leg having an upflow-pipe, a distributing-head centrally over the combustion-chamber and connected to all of the upflowpipes of one series of waterlegs, and additional distributing-heads each connected to a substantially equal number of upfiow-pipes of the remaining series of waterlegs for the purpose described.

In witness whereof I have hereunto set my hand this 24th day of March, 1904:.
