. Heaters, of which the following is a specifi'eation. I v I The invention relates to' such lmprovements and consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompany ing drawings, and the reference characters thereon, which form a part of this specification. Similar characters refer to similar, 7

Figure tical, longitudinal section of oneform of water-heater embodying my invention. Fig. 2"is a top plan view of the same with the inlet elbow removed. Fig. 3is a top plan View ofthe inlet elbow detached. Fig. 4: is a vertical cross-section taken on the broken line 44 inFigs. 1 and 2. Fig. 5 is a View similar to Fig. 1 of another form of waterheater embodying my invention. Fig. 6 is a horizontal cross-section'of the same taken on the broken line 66 inFig. 5.

This invention relates to the water-heater in which the water circulates through an inclosure containing steam heated pipes. J

Certain objects of the invention are to securegreater efficiency and economy in the use of the steam; and to increase the durability of the heater.

Other ob ects Wlll appear in connection 7 i withthe following description:

Referring to Figs. 1, 2, 3, and 4 of the drawings, lis the main casing, of general circular form in, cross-section, which casing is supported upon a hollow base, 2, from which it is separated by a horizontal plate or diaphragm, 8. The casing, 1, is provided near its lower end with a water-inlet, 4:, and at its upper end with a water-outlet, 5. The casing,x1, is surmounted by a head, 6,

containing an outlet passageway, 7, commu nicating with the water-outlet, 5. Within the upper end of the casing, 1, is a steamdome, 8, conforming to, but smaller than,

V the interior of the casing, said dome having an integral horizontal bottom, 9, containing numerous screw-threaded apertures adapted 1 of the drawings is a central, vertype of.

J Specification of Iletters Patent. Patented June 8, 1915 Application filed. July 8, 1914. Serial No. 849,848. 6 I Y to receive the upper reduced screw-threaded ends, 10, of a like number of vertical steamplpes, 11, the lower ends of whichpass down through correspondingly located apertures 1n the horizontal base-plate, 3, within which apertures the lower ends of the respective- .pipes are expanded to make a tight joint.

the: dome at the apex thereof, and extends upward therefrom through a close-fitting aperture in the head, 6, forming a sliding joint with the head, 6 which joint is made steam-tight and water-tight by means of a pac'kin'g, 13,and gland, 1 1.

The aperture in the head, .6, through which the inlet steam-pipe, 12, passes, is cov ered by an elbow, 15, bolted upon the top of the head, 6, with which'elbow is detachably connected a steam'supply-pipe,16, havinga controlling valve, 17 whereby the supply of steam canbe regulated. The elbow, 1,5, 7

thus forms a cap covering the aperaurein the head independently of said'steam-inletpipe so as not to interfere with'the movements of the steam-inlet-pipe. due to expansion and contraction. N

For certain purposes of the invention the cap for the aperture in the'head', 6, may be of any desired form, such as not to interfere with the movements of thesteam-inlet-pipe, while providing a means of connection for the main steam-supply-pipe,.but I prefer the elbow-form shown or some similar form whereby a [steam-chamber is formedsomewhat larger than, and communicating with, the opening in the st'eam-inlet-pipe.

In the use of the heater, steam is introduced from the pipe, 16, passing down through the steam-inlet pipe, 12, in somewhat expanded form and thence into the dome, 8, where it further expands and from which it passes down through the pipes, 11,

within which it is condensed,- the water of condensation draining into the hollow base,

2, from which it is conducted by a wastepipe, 18. The water entering the casing at 4 flows around the steam-pipes, 11, and upwardly between the dome, 8, and the top of the casing and out through the passageway, 7, absorbing in its course both the sensible and the latent heat from the steam which is condensed and converted into water in passing down through the pipes, 11. By connecting the passageway, 7, with the water inlet,4:, by means of a return pipe in a heating system, not shown, circulation of the water may continue in the usual manner.

Byintroducing the steam at the top of the heater through the pipe, 12, the first action of the steam is at substantially its maximum of sensible. heat uponthe outflowing water at its maximum temperature; while the steam is not subjected to the minimum temperature of the inflowing water until it reaches the lower portion of the pipes, 11, where it condenses, giving off its latent heat which quickly heats the inflowing Water.

The sliding joint at the stufling-box formed by the packing, 13, and gland, 14c,

affords freedom for expansion and contraction of the pipes, 11, avoiding injurious strains upon the connections between said pipes and the bottom, 9, of the dome and horizontal base-plate, 3.

In the form of my invention shown in Figs. 5 and 6, the casing, 1, has an integral head, 19, and is provided with an outlet passageway,20, through the head at one side of the casing. The steam-dome, 21, is mounted eccentrically within the casing nearer the side from which the passageway, 20, extends, and the top, 22, of said dome and the head, 19, of the casing are preferably substantially flat and parallel with each other. The space between the dome, 21, and easing, 1, through which space the heated water rises, becomes gradually restricted on the side toward the outlet passageway, 20, thereby tending to deflect the upwardly flowing water around the dome away from the outlet passageway and into the space, 23, between the top of the dome and the head, 19, thus causing much of the outflowing water to traverse a devious I path over a large area of the heated dome,

21, in reaching the outlet passageway, 20. Steam may be. supplied to the steam-inlet pipe, 12, in any known manner. As the steam-domeis free to rise and fall in ac eordance with the movements of expansion and contraction of the pipes, 11, there is practically no tendency for the connections between the steam-pipes and the dome and the bottom or baseplate, 8, to become loose.

The stufling-box formed by the packing,

13, and gland, 14, is readily accessible for,

adjustment or renewal by removing the inlet-elbow, 15. r
