IMPROVEMENT IN LOW-WATER INDIATORS.
The Schedule referred to in these ALetters Patent and making palrt of the same.
To all whom itmay concern:
Be it known that I, DANIEL WLEHL, ot' Giochi-- nati, Hamilton county,-State of Ohio, have inventedv certain new and useful Improvements in Low-water Indicators for Steam-Boilers.; 'and Ido hereby declare the following to be a s'uiiciently full, clear, and exact description thereof, toenable oneskilled in the art to which my 'invention appertains-to make and use it, reference being had Ato the accompanying drawing making partof this specification.'
y invention relates principally to the low-water indicator' for which. Letters Patent were granted to PETER W.Rn1NsHAGEN, assgnor to himself, DANIEL WIEHL, ANDREW P. LUsK, and .I oHN H. BUCKMAN, No; 102,433, datedApril 26, 1870; and
My invention consists- First, in theprovision, in connection with the bal-` anced floating valve, of av spherical .case surrounding the iloat on theexterior of the boiler, and a connecting-pipe to communicate from the case to the inside of the boiler, the pipe terminating at the required water-line.
Second, in connection with the devices described in the previous clause, of a diaphragm at the lower'part ofthe spherical case,` which serves as a guide for the float, and as `a break-water for preventing the water as it'enters the chamber, from driving the float and valve too hard against the seat.
Third, in a .certain peculiar construction of the break-water diaphragm byy which 'a rotary motion isgiven to the water as it enters the chamber, which serves to enable the valve to keep its own seat clean by an occasional rotary motion on the seat.
Description of the Accompanying Drawing.
Figure 1 is an axial or vertical central section of a low-water indicator embodying my invention.
Figure 2 is a cross-section, exhibiting the shape of the guide and break-water at the bottom of the spherical case.
Figure 3 is a detached perspective view of the under side of the break-water diaphragm, exhibiting the device for causing the water to revolve as it enters the chamber.
General Description..
boiler from the case B, `lerminating at the lower end at or near the required water-line nf the boiler.
The case or chamberB is vconstructed with a coticaljvalveseat, D, and is surmounted by. a steanwhistle, E. Y
The tloat F, which' is of sheet metal, and'as near spherical as possible, i's fitted with'a valve-stem, f, and` counter-weightf, the latter, although it is guided, as shown, serving to sustain` the stem f iu the vertical position.
The conical seat' Dand float-1li f j", are embodied Y in the Letters Patentllo. 102,433,1aforesaid.
' The provision of ,th`e spherical' case B to iuclose the float on the outsideof the boiler, and the pipe G to communicate .with the interior ot' the boiler, enables the valve f to open and"` close by the falling or rising of the water in the boiler, -much more promptlythanl when the floatis located .inside the boiler, as, the' instant the water falls below` the end of pipe C, the case B is emptied of water, and the float F falls so vthat steam is permitted to passkand'blow the whistle,
` When the water again rises so as. to cover the end' of pipe C, the water rushes up and fills the chamber B, lfloats the ball F, andcloses the whistle;
In order to prevent water `as it ente-rs the chamber B from driving the float Fff too forcibly against the scat D, I provide vthe break-water diaphragm G, which prevents the water striking squarely against the bottom of the oat ll, and directs it wholly up the sides.
Ihe diaphragm G also serves, in the manner shown, as a guide for the weight f ofthe iloat. i
The seat D is kept clean a1itomatically,'by the oc casional rotation of the ,stem f on the seat, which rotation is caused by the rotai'y motion of the water as it enters the chamber B.
lhe water is compelled to ,rot-ate on passing the plate G, by the spiral grooves g, which are provided on the under side of the plate, (see fig. 3.).
