Guide where "33 ehe gear 29. Them-heirs and geahihg %1emetal and to withstand the high pressures used many -boilers';; the gwallsf of the; float must "necessaril be of consiarable thickness to prevent the float from collapsing. In any event, whether theiiifloatr be so. con structed or not the weight of the float and of the rod is-so large, particularly where the water level is twenty-five or .thirty feet 9 high pressure and the buoyant effect of the float acting upon the unbalanced portion of the weight directly connected with the float, is sufiicient to positively andaccuratelymove the rod- 25 so that its lower portion will afiord a true indication of .the water level intheboiler.-

It will be noted that all of; the gearing and parts connected with the counterbalancing mechanism are entirely enclosed and that there is no need for .stuifing boxes of any kind in connection with, said mechanism.

To automatically shnt ofi' the flow of water from the column 14 in casenof accidennias for example breakage of the glass .15,';the .rod 25 is provided abovethe valve seat 18 with a valve 36 which, ,when,the fioat;.24 drops, engages the valve seat. 18- andinterrupts communication between the upper and .lower :parts of the column 1 4. glhijs: action results from the rushof water through the column due torelieving the pressure on its lower end below thevalve seat; 18. To test the apparatus, the samecondition maybe created by opening the valve 20,.- for. which condition the operatiOfl-Qfthd-Erod 25. as viewed through the sightglass-15 and the flow of water through the -drain pipe 21 affords a positive indication of whether the mechanismf'is in proper. working order. When the valve 36 hasbeen thus brought into engagement with itsvalveseatfor any reason, it would remain there, unless the pressure in the. lower part of the .columnl l were again brought up to the. pressure.in theupper part of the clolumn and this condition may be established by opening the valve 23'. When the pressuresin the upper and lower parts of theecolumnhavenbeen equalized in this manner, the buoyant effect of the floatasserts itself and thezrod 25.is lifted tomove the valve'36 away fromits seat, after which the valve-23 is. closed, whichis the normal condition ofsaid valve for proper. operation of thelevelindicating devices. 'My invention thus; provides a means for automatically stoppingthe escape of water from the boiler. andyalso; for p'reventing loss of pressure in the boiler in case of a s d nt; o amp e ka ep the si'ght glass 15, or the lower "part bf the water "column and provides in addition,

means for reestablishing operative condirepair if desired. It will furtherbe understoodthat Ido not limit myselfin carrying outmy invention to the particularembodiment shown and described asI may employ equivalents thereof known to the art at the time of the filing of this application without -departing,.;trom the scope of the appended claims. What I claim is-:.

- p 1.] In a device of the vclass described, the combination of a. float, chamber,,;for connection with a boiler, afloatin said chamber to,respond to .,water level therein corresponding with the I .water level I of the boiler, said chamber having. a. lateral compartment extending therefrom in open communiea tion ,with. said chamberand extending vertically a ove an i e w .sa dtfloa -in p allel. relation with said float chamber, said chamber and compartment. acomprising a single receptacle having continuouS-and'imperforate; .wallspompletelya; enclosing; the

same and, .having exterior. communication only .throu h said. boiler gconnectigns a .counterweig it. .in saidqvertical extension, toothedjrods or racks. projecting upwardly from said floatand counterweight, agear contained; ;in said compartment. engaging said toothed ,rods'or. racks, a tube extending dOWnWardly from :saidchamber and having a transparent wall-at its lower portiomand an. indicating rod. extendingdownwardly from said ;fi0at through. said .tube to .indicate the level :of said-float. through said tr nsparent wall. 1

=7 2.- .In Za- .device 10f the {class described, the combination. of a float chamber for connection;with a.-boiler, afloat in saidlchamber to respond to Water level therein corresponding .with thewater level of. the'boiler, said chamber, having-a' lateral compartment extending therefrom in open communicationwith-said chamber and extending verticallyrabove and below-said; float in parallel relation with said float. chamber, said chamber and compartment comprising asingle. .;receptacle havingv continuous and 5 imperforate walls completely enclosing the same saznd having exterior communication only through said boiler connections, a counterweight in said vertical extension, toothed rods or racks projecting upwardly from said float and counterweight, a gear contained in said compartment engaging said toothed rods or racks, a tube extending downwardly from said chamber and having a transparent wall at its lower portion, an indicating rod extend- 10 ing downwardly from said float through said tube to indicate the level of said float through said transparent wall, and a valve member carried by said indicating rod for closing said tube above said transparent wall when said float descends below a lower position.

In witness whereof, I hereunto subscribe my name this third day of August, A. D.
