Application filed April 20,
This invention relates to a water level indicator or water gauge that is suitable for high pressure boilers. The invention will be understood from the description in-cnnec tion with the accompanying drawings, in
which Fig. -1 is a front view of an embodiment of the inventlon; F 1g. 2 1s a side view of the same and Fig. 3 is a section on an enlarged scale, along the line 3-3 of Fig. 2.
In the drawings, reference character 10 indicates a pipe that may be connected water space of the pipe 10, by means of the connection 15 that is provided with a shut-01f valve 16. A drain pipe 17 having a valve therein (not shown) leads from the valve 16.
The water gauge is of the type that is provided with flat side pieces of glass, between which the water column can be viewed, and
comprises a central flat holder member 20 that has different portions thereof offset in the plane of the flat member so that there are vertical grooves; or slots along the sides 0 the holder member 20. The member 20 has enlarged portions 21 and 22 along its edges and a similar central enlarged portion 23.
Longitudinal narrow sections 24 and 25 of the member 20 extend between theenlargedportions. The narrow sections 24 and 25 are provided with longitudinal chambers formed by slits 26 and 27 that terminate short of the respective ends of the narrow portions. A
transverse hole or bore 28 is provided with a closure plug 28 and extends through the enlarged portion 23 to connect the lower end of the slit 26 with the upper end of the slit 27 Similar holes or bores 29 and 30 extend from the upper end of the slit 26 and the lower end of the slit 27 respectively, through the 46 ienla-rged portions 21 and 22 to the pipes 31 and 32, which 'and 16, respectively.
are connected to the valves 14 Flat glass strips 33 and 34 are provided over the open edges of the slits 26 and 27, which form. narrow elongated openings in providing the water BAYONNE, NEW JERSEY, A COB-BORATION OF NEW JERSEY nrsn-rnnssnnn WATER; GAUGE 1926. Serial No. 103,243.;

the glass strips. Sheets 36 of transparent material, suchas mica, are placed next to the gaskets 35 on the sides toward the glass strips 33 and 34, and brass strips or shims 36 with slits corresponding to the slits 26 and 27 are placed between the mica sheets 36 and the glass strips bridging the joints betweenthe edges of these glass strips and the sides of the recesses in which they are seated. Side or cover plates 37 provided with recesses 38 for the glass strips 33, and side'or cover plates 39 provided with recesses 40 for the glass strips 34 are clamped by means of the bolts 41 andnuts 42, so as to press the glass strips into position to close the sides of the slits 26 and 27, resilient material such as packing 43' and 44 being interposed between the plates and glass strips to prevent breaking the glass. The side plates "37 and- 39 are provided with slits 45 and 46, respectively, having converging walls, these slits being aligned with the slits 26 and 27.
It will be obvious that same level as that in the pipe 10, and the water when the valves 14 f and 16 are open, the water will rise in the chambers formed by the slits 27 and 26 to the level can be observed through the glass strips alongside the chambers. The connections between the pipes 31, 32 and the valves 14, 16 is such that the gauge can be turned at rightangles, as shown in dotted lines in Fig. 1, or to any other convenient angle, so as to face the position most suitable from the observers standpoint. The gauge will preferably' be located at such a helght that the normal water level of the boiler will be about on a level with the upper end of one of the columns, or the lower end of the other column, or-the gaugemay be so located that when the water level is below the top of the lower column, this will indicate an abnormal low water level in the boiler. The slits 26 and 27 chambers areso located with respect to each other thatthe upper end of one extends slightly above the lower end of the other, so that. the water level will be seen in the upper .one before the lower one entirely filled with water.
By this invention, the use of-long pieces of glass 211011 the sides of the water chamberis avoide and'shorter pieces that are not so apt to break can be used. While two communicating chambers for water columns have beendescribed in the illustrative embodiment of this invention, it is to be understood that a larger number-may be used and other variations may be made without departing from the spirit or scope of the inventlon.
I claim:
1. A gauge glass comprising a high pressure holder member having overlapping elongated ofi'set portions and a portion connect ing the offset portions together, said ofi'set portions each having overlapping chambers formed by longitudinally extending slits extending through said portions and connected together by a bore extending through said connecting portion, a pair of elongated glass strips covering opposite sides of each chamber, a pair of cover plates disposed exteriorly of each pair of strips, and bolts passing through each pair of cover plates and said holder member;
2. A gauge glass comprising a high pres-- sure holder member having overlapping elon gated offset portions and a portion connectmg the ofi'set portions together, said ofl'set portions each having overlapping chambers formed by longitudinally extending slits extending through said portions and connected together by a bore extending through said connecting portion, a pair of elongated glass strips covering opposite sides of each champlates disposed exteriorly her, a pair of cover of each pair of strips, and means holdin each pair of cover plates in position.
3. A gauge glass comprising a high pressure holder member having overlapping elongated ofit'set portions and'a portion connect-.
ing the offset portions together, said offset orti'ons each having overlapping chambers ormed bglongitudinally extending slits extending t rough said portions and connected together by a boreextending through said connecting portion, a pair of elongated glass strips covering opposite sides of each chamber, a pair ofcover plates disposed exteriorly of each pair of strips, through each pair of cover lates.
