J. J. PARKINSON HEATING COIL FOR HOT WATER SYSTEMS Filed Auz. 9. 1923 A TTORIVEYS Patented Mar. 27, 1928.
UNITED STATES JOHN J'. PARKINSOII, OF CHICAGO, ILLINOIS.
HEATING COIL FOR HCHI-WATER SYSTEMS.
Application filed August 9, 1928. Serial No. 656,516.
My invention relates to improvements in hot water systems, and it consists in the combinations, constructions, and arrangements herein described and claimed.
An object of my invention is to provide a novel heating coil or tube in a hot water system in which the water heating coils are immersed in the water within the boiler, whereby the pipes will not immediately cool as soon as the fire goes out, as is the case when the coils are disposed in the fire box, but will remain hot and will continue to warm the water therein until the water in the steam boiler is the same temperature as the water within the coil pipes.
A further object-of my invention is to pro-.
vide a device of the character described in which the heating coils will not be burnt out through use, since they are immersed in the water in the boiler and cannot therefore be raised above a predetermined temperature.
A further ob]ect of my invention is to provide a device of the character described which is simple in construction, and durable and efficient for the purpose intended.
Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.
My invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is a front elevation of the device,
Figure 2 is a section along the line 2-2 of Figure 1, and
Figure 3 is a section along the hue 3-3 of Figure 1.
In carrying out my invention, I provide a steam boiler 1 which has a fire box 2, fire tubes 3, and a water containing cylinder 4. The fire tubes 3 are submerged in the water 5 of the cylinder. The hot gases of combustion pass from the fire box 2 through the fire tubes or flues 3 and into the chimney 6. The heat given up by the gases as they pass from the flucs 3 passes into the water 5 and raises the temperature thereof. A grate (not shown) is usually provided beneath the fire box 2 so as to remove the ashes from the fire box as they accumulate' I dispose a tube 7 in the cylinder 4 and submerge it beneath the water 5, as is clearly shown in Figure 2. The tube 7 has a part1- tion 8 therein that runs substantially the entire length of the tube. The tube 7 is closed at its inner end, as at 9, and the partition 8 stops a short distance from the end 9, as at 10, whereby a continuous passageway 18 provided through the lower half of the tube to the end 9 and back to the outer end of the tube 7 along the upper half of the tube. A cross fitting 11' having four openings therein is secured to the outer end of the pi e 7. A pipe 12 communicates with one of t 1e openings in the crossfitting 11 and also communicates with a water reservoir 13. A second pipe 14 communicates with another one of the openings in the cross fitting 11 and is connected at its other end with the lower end of the reservoir 13. It will be noted from Figure 1 that the pipe 12 communicates with the reservoir 13 at the top thereof and the pipe 14 communicates with the reservoir at the bottom thereof.
In Figure 3 I have clearly shown a partitIon 15 in the cross fitting 11 that is adapted to direct the water from the pipe 14 into the lower half of the pipe 7 and to direct the water from the upper half of the pipe 7 into the pipe 12. A plug 16 closes one of the openings in the cross fitting 11. The partition 15 is spaced slightly from the partition 8 so as to provide an air passage 17 which prevents the pipe 7 from becoming air bound and thus prevent circulation of the water. If it were not for this passage 17, the air collected in the pipe 7 when the water is drained therefrom would likely become trapped in the pipe and would therefore prevent circulation of the water through the pipe. The assage 17 permits this air to escape direct y to the pipe 12, thus allowing the water to enter the pipe 7.
From the foregoing description of the various parts of the device, the operation thereof may be readily understood. A water inlet pipe 18 is connected with a source of su ply (not shown) and communicates with t e bottom of the reservoir 13. A hot water outlet 19 communicates with the to of the reservoir 13 and is connected with t e pi in of a house. When a fire'is built in the re ox 2, the water 5 is heated by means of the hot gases passing through the fines 3. This hot water in turn heats the water within the pi e 7 and causes a flow in the upper half of t e pipe 7 in the direction of the arrow. This flow is due to the fact that the water in the pipe 7 expands when heated and therefore flows upwardly through the pipe 12 and into the reservoir 13. The cold water from the lower portion of the reservoir 13 flows through the pipe 14 and into the lower half of the pipe 7 to take the place of the water that has flowed from the pipe 7 to the reservoir. As long as the water 5 is hotter than the Water in the reservoir 13, there will be a continuous flow of water from the reservoir to the pipe 7 and back to the reservoir again. It is obvious that the pipe 7 cannot be heated to such a hi h degree of temperature as to burn away the pipe, since the pipe is submerged in the water 5 and does not come into direct contact with the flames, as is the case when the heating coils are disposed in the fire box 2. The pipe 7 will therefore have a very long life. Nor will steam be formed in the pipe 7 since the water pressure is usually considerably greater than the highest steam pressure present in the boiler.
Furthermore, the water within the'pipe 7 will continue to be heated for a considerable length of time after the fire in the fire box 2 has gone out due to the fact that the water 5 remains hot for quite a while after the fire has gone out.
The water in the reservoir 13 is under the same pressure as the water in the pipe 18,
this pressure being sufficient to force the water through the pipe 19 and into the piping system of the house. As fast as the water is drawn from the pipe 19, cold water flows into the reservoir 13 through the pipe 18. This Water is directed to the pipe y means of the pipe 14.
In case the pipe 7 becomes clogged with foreign matter, it is merely necessary to close the gate valve 20 and to open the sediment cock 21. The pressure within the reservoir 13 will reverse the former flow oi the water and will cause it to pass through the pipe 12, through the pipe 7, the pipe 14, and out through t e sediment cock 21. A comparatively small amount of water in the reservoir 13 is sufiicient to thoroughly cleanse the pipe 7. When all of the foreign matter has been drained off, the sediment cook 21 is closed and the gate valve 20 opened, whereupon the normal circulation of the water is resumed. The reservoir 13 is also provided with a sediment cock 22 by means of which the entire contents of the reservoir can be drained if desired.
The device may be readily installed in homes and hotels with but sli ht alterations being necessary in the steam oilers used in these places.
I claim:
In combination with a tube adapted to be disposed in the water in a boiler and having a partition therein dividing the tube into water traversing compartments arranged in series, a fitting connected to said tube and having a cold water inlet, and a hot Water outlet, a partition in said fitting separating the cold water inlet from the hot water outlet, said partition being slightly spaced from the front edge of the partition in said tuge to prevent the trapping of air in said tu e.
