HOT-WATER HEATING SYSTEM.

Specification of Letters Patent.

Patented Dec. 19, 1916.

Application filed November 9, 1914. Serial No. 871,193.

To all whom t may concern:

Be it known that I, FERDINAND LANG, a subject of the Russian Empire, residing at Colorado Springs, county of El Paso, State of Colorado, have invented certain new and useful Improvements in I-Iot-lVater Heating Systems, of which the following is a specication.

This invention relates to hot water heating systems, and its object is to provide a novel and improved means for establishing a circulation of the water, together with a connection which permits the heating of water in a stand boiler for domestic purposes.

The herein-stated objects are attained by means of 'a combination and arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawing in which- Figure 1 is an elevation of the boiler; Fig. 2 is a central vertical section thereof; Fig. 3 is a plan view, and Fig. 4 is a horizontal section on the line 4-4 of Fig. 2.

In carrying out the invention there is provided a sectional boiler, the units or sections 15 of which are superimposed and constructed and arranged to form communicating water chambers around flues and smoke chambers which carry the smoke, hot gases and other productsl of combustion. lEach section 15 comprises a cylindrical shell 14, horizontal top and bottom plates 14It and 14h, respectively, constituting the upper and lower faces of the section, an intermediate plate 14n, and a vertical flue 36 extending between the top and intermediate plates and opening therethrough. In the center of the topY plate is an upstanding nipple 32, and at the center of the intermediate plate is a depending nipple 33. A cylindrical wall 33@l extends concentrically and in spaced relation with the shell 14, between the walls 14b and 14C, thus forming an annular water space which is in communication with the water chamber formed by the shell 14 and the walls 14c and 14a. In assembling the sections, the bottom nipple 33 is screwed into the top nipple of the next section below, the nipples being screw-threaded for this purpose, and the sections are so assembled that the flues 36 are alternately on diametrically opposite sides of the vertical center line of the sections, inorder that the products of combustion may have a tortuous path. When the sections are thus assembled an annular smoke chamber is produced between the top wall 14a of a section and the intermediate ,wall 14c of the next section above, the side Walls of this chamber being the wall 33@- of the upper chamber and the nipples connecting the sections, whereby the smoke chamber is surrounded by the aforementioned annular water space. The flue 36a opens at its lower end into this smoke chamber and its upper end opens into the next smoke cha mber above, and from the last-mentioned smoke chamber a flue 36 connects with the nextgsmoke chamber above, but on the opposite side, and so on throughout the entire series of sections. The products of combustion therefore take a tortuous path and a large heating surfacey is produced, resulting in a rapid heating of the water and consequent fuel economy. The water circulates from one section to the next through the nipples connecting the same at the center.

The shell 14 of each section 15 is reduced near the top to form an external shoulder, and the bottom of the section has a depending external annular flange 34 of a diameter to fit snugly around the upper end of the shell of the next section below, and of a length to seat on the shoulder thereof, to make a tight connection between the sections. A clean-out door 8 is also provided.

At 5 is indicated the fire-pot of the boiler, the same being mounted over an ash pit 1, and provided with a feed door 7, a clinker door 6 and a grate 2, supported on seats 3.

The ash pit has a door 4. The fire-pot isvk Y closed at the top by a dome 5a and is surrounded by a water leg 15a. Above the dome is a water space which communicates with the water space 15a and with the water chamber of the lowermost one of the sections 15 through the bottom nipple 33 of said section. Smoke flues 36a extend through the water space above the dome and connect the fire-pot with the smoke chamber of the lowermost section.

The section which forms the top of the boiler has a smoke chamber 11, and above the latter a water chamber 16. A flue 36b connects the chamber 11 with the smoke chamber of the section 15 next to the top section, and the water chamber of the lastmentioned section is connected by nipples 32a to the water chamber 16.

The water chamber 16 has outlets 13 leading to the radiators, and an outlet 17 con- ,nected to the water space 15a.

nected to the top of a reservoir 16a'in the form of an ordinary stand boiler mounted alongside the boiler. On the other side of the boiler is a similar reservoir 15b. VThe reservoirs are mounted on suitable supports 22. The reservoir 15b has a connection 29 -at the top with the water chamber of the section 15 next to the top section, and at the bottom a connection 24 with the water space 15a. rlhe reservoir 16a has a connection 19 at the bottom with the water space 15a, with a` valve 2O in said connection. By reason of these connections a circulation through the reservoirs is established. The water passes into the reservoir 15b from the water chamber of the section 15 next to the top one and flows back to the water space 15a. The water in the chamber 16 passes into the reservoir 16n and flows back into the water space 15a.

In the nipple connection 32a is a valve 35 provided with an operating handle 12 on the outside of the boiler. This valve is for the purpose of cutting off communication between the water chamber 16 and the water chamber below to which the reservoir 15b is connected, so that the circulation through the reservoir 16a may be cut off.

The return 21 to the boiler from the radiators is connected to the reservoir 16a at the bottom thereof. The water chamber 16 has a connection 30 with a safety valve or shockabsorber. To the reservoirs 15b and 16a are connected thermometers 28. The reservoir l15b has an outlet 27 at the top, and a washout 25 at the bottom, provided with a valve 26.

To the smoke chamber 11 is connected an outlet 10 provided with a damper 12 for regulating the draft. A cold draft door 9 is also provided, the same being in line with the outlet 10.

lThe cold water supply inlet to the sections 15 is indicated at 28, the same Vbeing cona When the heating system is in use the water pressure is left on. Y

The reservoir 16a is designed to hold the eXtra amount of water required for the heating plant, and the reservoir 15b is for the purpose of supplying hot water for the kitchen, bath, laundry.I etc. If the heat in the heating plant is to be reduced, the valve 2O can be closed, whereupon the water for the heating plant will still circulate through the reservoir 16"L and also through the pipes 13, and then the heat can be regulated by the valve 35. rThe heating system can alsoy be entirely cut out by closing the valves 35 and 20, whereupon the water circulates through the reservoir 15b only. lf all the hot water should be taken from the reservoir 15", this will not affect the heating plant because the intake 28'will force water through the sections 15 onlyand out through the corresponding pipes 29 and 211, and the water in the chamber 16 and the reservoir 16a will not be affected until the water in the sections is again heated up.

l claim:

1. A water-heater for hot water heating systems having connections to the heating units of the system, a circulation reservoir mounted outside the heater and having connections with the top and bottom thereof, a valve in the bottom connection, and a return vfrom the heating units ofthe system connected to the reservoir. Y

2. A water-heater for hot water heating systems, said heater having separate water chambers, a hot water reservoir mounted outside the heater and having circulating connections with one of the water chambers, outlets from the other water chamber to the heating units of the system, a circulation reservoir mounted outside the heater and connected to the second-mentioned water chamber, and provided with a valved return connection to the heater, a return from the heating units of the system connected to the reservoir, and a valved connection between the water chambers.
