HEATINGSYSTEM REGULATOR.

Specification of Letters Patent. Patented Oct, 16 1917,

Application filedMay 18, 1917. Serial No. 169,578.

To all 'I0/wm t m07/ concern.' Y

`Be [it known that I, CHARLES'E. ANDER soN, a citizen ofthe United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement lin Heating/#System Regulators, of which the following is a specification. f

This invention is a. relief device fora heating system, particularly `vapor heating systems of very little pressurewhere eX- treme accuracy is required. Thefobject of the invention is to provide va device which will relieve the boiler of any excess pressure with great promptness without permanently removing from the boiler any material portion of the liquid. The invention consists in a device capable of carrying out the'foregoing objects; which can be very easily and cheaply made; which is satisfactory in loperation, and is not readily liable to get out of order. More particularly, it consists .in the special features and vdetails of construc- .tion hereafter more fully set forth in the 25A ter line l` of Fig. 2.

yFig. 2 is a corresponding view takenon the irregular line 2-2 of Fig, l.

1 In carrying out `this invention, an over- How chamber lortank connected to theheating system to be regulated is provided. lThis regulating tank may assumeany suitable form, and still have certain essential parts of this invention inclosed therein. v In the highly developed form of the device illustrated in thed'rawing,this tank comprises in its outer walls-an upper chamber 10, a

casting of relatively large cross-section, a pipe 12, of smaller` cross-section screw threaded therein and closedby any suitable means, such aslthe closure capllg. Water and steam from the boiler to be regulated, not shownmust be admitted to the regulating tank just referred to and carried to a point nearjits bottom. In the particular case here illustrated, this isaccomplished by providing in casting 10 an internal wall 1G forming the interior chamber 18, connected to the boiler, or its equivalent (not shown) through one or both of the ports 20, there `being screw threaded into the bottomof the internal casting 16 a pipe 22 extending downward inside vof pipe l2 to a point near, but above, the cap 14. This construction affords an annular passageway 24 'leading from the bottom of the regulating tank between pipes 12 and 22 into the upper cham ber 26 of the regulating tank. In order to carry out this invention, the regulating tank must also be provided with a pipe or Dassageway'leading fromV a point near the bottom of the regulatingtank, but above the bottom of pipe 22 to a lpoint near the top of the upper chamber 26 of the lregulating tially equal to the effective cross-sectional areay of passageway 341:, between pipes 22 and 28, and less than the effective cross-sectional area of the passage 24, heretofore described. The reason for this is that pipes 28 and 34 are designed to take kcare of.` the normal working of the devicev while passage24; is intended first to afford relief from excessive pressure and from a partial or complete accidental closure of passage 28, and second,

to afford a ready return for liquid forced into chambers26 through passage 34 so it should be large enough to surely afford such relief. The 4proportions may, however, be varied, if desired.

Simply for `clean-out purposes in constructing the device, 4the casting 10 is provided kwithV an Vopening 36 normally closed bya. screw threaded cap, not shown in the y drawings. n

l In the extreme top of casting. l0 is an escape pipe 3S hereafter referred to asa discharge lport, terminating in an extremely shallow, wide, relief chamber 40 having on its top a relief outlet 42 which may, if desired, be Connected to a pipe leading to a chimney or the like. Inside of this relief chamber 40 `and directly opposite the entrance of the pipe 38 therein is al suitably supported baille plate 44 of any suitable design which will insure the prevention of the tank. In the preferredform of invention, .illustrated in the drawing, this is accomllO ,L Y Y expense. 3f-replacements direct passage of liquids and gases entering the reli-ef chamber 40 from pipe 38 to exit-42.

In the operation of the device Vof this invention, assume that one or both of the openings 20 are connected tothe boiler to be regulated (one opening 2O being suitably closed if only-one is being used) and that the device shown in the drawing is filled with water up to a point approximatingthe discharge end 32V of pipe 28. When, now,

thee-"pressure in. theboil'er to be Vregulated rises a little, 'water from the boiler is forced through port 20 in the chamber 18, thence down' passage 34, thence under normal conditions up pipeQS otherwise up this pipe rand pipe 2l into uppery chamber 26, and

thence through passage 3S into relief chamber 40. Here the water has a chance to "spread out and any steamer gas carried with it has a chance to get out Vof the water Vand pass around baille plate'llri, and thence out through discharge port 42. The steam or gas goes out in bubbles, and as long as the pressure inv the boiler is not excessive, can continue'to doV so until the pressure in the boiler is relieved, when gravity'will carry the-.water inthe upper part of the system just described back into the chamber 26, thence through passages 24 and 34, back .tothe boiler. Owing tothe fact'that the top yoflpassage 28 is below the'top of passage 24, a large .part of the water returns through passage' 211e without goinginto chamber 40 at all,eXcept in the case of passage 28 being stoppedup as heretofore noted, whereupon the water and gases travel fpartially' or wholly up passage 24e into chamber 26 and thence into l0 as described."

By the use of the device of this invention,

variations in pressure, large ors'mall, may

j regulating tank having an entranceand a Yattached to said discharge port provided with a suitable baille plate, and a discharge discharge port, a supplemental relief tank port of its own, a pipe leading from Athe entrance port of the regulating tankto` a point above the bottoniV of said tank, another pipe leading, from a point slightly above the bottom of 'said first mentioned pipe, and from in close' proximity 'thereto to a point adjacent to the discharge port of the` regulating tank, for the purposes set forth.
