To all whom it may concern:

Be it known that I, PIERRE BARNEs, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Water-Heaters or Steam-Generators, of which the following is a specification.

This invention relates to thatclass of heaters which are designed to be utlllzed fol warming the apartments of a building by the circulation of a body of water or steam,

' through a system of pipes and radiators and its object is to improve the construction of heaters and parts thereof constructed su'chheaters toprovide one having exceptional eificiency.

. The invention consists in the novel con-' struction and combination of parts, as will be'hereinafter described and claimed.

1 The accompanying drawings illustrate in accordance with 'my invention.

Figure 1 is a vertical cross sectional view of an embodiment of the invention; and Fig. 2 is a horizontal section of one of the heating members thereof.

The'reference numerals 10 designate the main, or circulating, water-heating members. These members are each comprised of and a centrally disposed boss, or hub, 12 co'mmunicatively connected therewith from diamet of the respective circular portions. Intermediate the boss-openings of each such memhers is a partition 17 arrangedto afford an ;indepeudent communication through the arm'lh between the opening 15 and the circular chamber upon the one side and a like connection through the arm 14 between the other opening 16 andthe chamber from the. other side. Thes members may be employed alternately with ancillary heating "members 18. The-members 1b severally coneist of a lenticular shell of less diameter than that of said circulating members and having a centrally disposed outlet opening 19 at the top, and an inlet opening 20 below, the latter being located centrally or otherwise according to the location of the member in the series to conveniently accommodate the water-supply pipe 21 which enters the lowermost member. Said members are communicatively connected by tubular fitopenings.

tings 22 which are socketed in the respective Where the heater is constructed to be used for the generating of steam, a blow-oft pipe 23 would desirably be connected with the lower member, and a down-flow pipe 24; would be utilized to make communication between the upper and lower compartments of the correspondingly disposed members by being extended through apertures provided in the intervening partitions 17. This downfiow pipe is of less diameter than the tubular fittings 22 between the several members to afford annular passages 25 for the upflow of the water between the adjacent heating members. The upper of said members is ad- .vantageously made of greater diameter and depth than the circulating members therebelow to furnish an extended water surface to facilitate the disassociation of the steam from the water and also to provide ample storage capacity for the liberated steam.

27- represents a pipe connected with the top member of a series for the outflow of hot water or steam, as the case maybe.

The furnaces 28 and casings 29 for the heaters may be made in various ways and require no special description. The illustration shows a furnace adapted for burning fuel, such as coal or wood, and'is providedwith a grate, denoted by 30.

1 The operation of the heaters may be explained as follows: a suitable fire being'had within the furnace will act most directly upon the lower heating-member of a group 7 and thence the flames and other hot combus tion products pass upwardly through the spaces of the circulating members 10 and will, after parting with a large proportion of its heat, escape through the smoke outlet The ancillary heating mcmbers 18 serve as battles to cause the hot gases to be directed to effectively subject the exposed sur faces of the heating members 10 to the action of the heating agent. The members being thus affected will heat the water causing it have a movement upwardly from the lowest to the highest heating-members, passing freely through they ancillary ones, but retarded in the flow through the circulating members. The manner. in which the water is directed in itspassage throughthe said Icircu'leting members will be understood .lower members by the downfiow pipe from an inspection of Fig. 52 wherein represented by darts the current courses. l ore particularly, the water enters the in s of such a member from below and diverted by the partition 17 to first fiow radially out word through the hollow arm 13 into the annular chamber 11 wherein the body oi. Water is caused to flow in two semicircular branches to the diinnetriczilly opposite side of the member whereat it reunites and flows {is a single stream through the other arm 143% to the cavity in the boss which is above the partition, whence it flows from the meml'ier. In the adaptation of the devices to the uses of a steam heater, the circulation of the ter is established between said upper and which being more remote from the direct uction of the heating agent then the sin-rounding fillings 20, thus causing a difference in the temperatures of water within the pipe from that outside with it corresponding;- ditfercnce between the specific gravities and thus insure a descent of the waterwithin the pipe While the water feturns upwardly within the successive members and their connecting tubular fittings. It *ill be observed that said down-flow pipe opens on the opposite side of the partition 17 in the boss of the highcstmembcl" 10 from that to which the Water circulating upwardly from the lower members is delivered. struction, the water which enters suid high est member is compelled to circulate through one of the two oppositely extending arms, through the circular shell and through the other arm before it can pass down through the pipe 25. This circulation of the water insures a perfect separation of the steam from the water and thereby gives the ll'itttdl' a maximum capacity for generating steam. The pipe 27, which carries oil the steam communicates with the boss of the highest member at the side of the partition on which o the pipe 25 opens in order to further insure the complete separation of the steam from the Water.

What I claim, 1s-

1. A heater com risin e series-of sneer-- posed water-holding members having trally arranged connections for the upliow of Water between the successive members, tlle upper of said members being arranged to afford a horizontalcirculation of water therein, and a connection disposed axially of the aforesaid connections and making an in dependent communication between the upper and lower members, so as to cite ct the re turn of the water to the latter after a circulotion thereof has ensued in said upper member.

tion t Because of this conmembers, of it plurality of Watenholding' ers avenged alternately of said circumembers, each of said circulating compr s up; a. continuous outer shell, a. co trelly disposed boss, and

two oppositely extending arms connecting said boss and shell, each boss having a. partilverein with e passage at one side therele rdin from its lower end to one of said at and a passage its other side leading i ron'i its upper end to the other arm,

tween said water-holding members and the in. s o said circulating members, said s runs superposed members terminating at the bottom with a Water-holding member and at the top with a circulating member, a
