UNITED STATES" JOHN J. DAlLY, OF READING, PENNSYLVANIA.
WATERPG-AGE FOR BOILERS.
Specification of Letters Patent.
Patented July 4, 1916.
Application filed J anuar'y 17, 1916. Serial No. 72,388.
To all whom it may concern. Be it known that 1, JOHN J. DALY, a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new useful Improvements in Water-Gages for Boilers, of which the following is a specification.
This invention relates to improvements in water gages for boilers or like containers, and the object in the present instance is to provide a simple and effective means of positively determining the location of the water surface by permitting a view of the interior of the boiler.
The invention consists primarily in arranging a series of transparencies in vertical alinement, preferably arranged in two vertical rows, alternately arranged, so that the 2 surface of the water may be viewed from one of said points at all times, the alternate arrangement covering the entire' distance over which the water surface in its rise and fall will travel. The arrangement is made possible by means of a hollow casing, provided with a removable transparency, preferably of glass, and provided with a suitable water tight washer and a means for holding the parts in position in the casing.
The invention differs materially from the well known water. gage in the form of a glass column, having communication with the interior of the boiler, and by means of which the -water supply is supposedly accu- In devices of this character, it frequently happens that the communication leading from the glass to the boiler becomes clogged with foreign substances, are this interferes with the accuracy of the indication in the glass, so that a true reading of the waters height cannot positively be insured.
In my present invention, I provide for a.
viewof the water actually in the boiler, and
there is no possibility of error due to faulty parts, and, as the sights are arranged alternately, as shown, the view may be taken at any point in the series and the reading will always be true.
The invention is more fully described in the following specification and clearly illustrated in the accompanying drawing, in which Figure 1 is a central, longitudinal, sectional view of my device, in position in a boiler. Fig. 2 is a detail view, partly in section, of the casing member. Fig. 3 is a detail view of the transparency. Fig. 4: is a detail view of the rubber ring. Fig. 5 is a detail view of the retaining ring. Fig. 6 shows a series of the sights applied to a boiler or like water container.
The numeral 1 designates the casing member, which is formed with a reduced, exter nally screw-threaded inner end, 2, for attaching it to the boiler. The casing is hollow, and its exterior is preferably squared to provide easy means for inserting it in the boiler. The interior of the casing is formed with varied diameters providing shoulders 3 and 4, and the outer extremity of the casing is screw-threaded internally, at 5.
The numeral '6 designates a transparent body, preferably of glass, the inner surface of which is adapted to seat on the shoulder 3 of the casing. This body 6 is formed with a reduced outer end, 7, and its central. portion is slightly tapered, as at 8.
The numeral 9 designates a rubber ring, adapted to fit over the reduced end of the body 6 and having an interiorly tapered surface 10 adapted to bear against the tapered portion of the body 6, while its inner surface 11 is adapted to rest on the shoulder 4 of the casing.
The numeral 13 designates a retaining ring, screw-threaded externally and adaptedto enter the screw-threaded end of the casing and bear against the rubber ring 9, so
that when it is drawn up tight, it serves to expand the ring 9 and thus insure a water tight joint, and also to retain the glass body 6 in position. The ring 13 is preferably formed with a square or hexagonal head 15 by means of which it may conveniently be drawn up with a wrench. I
Thedevice is easily taken apart for cleansing and as easily re-assembled. There are no easily frangible parts, and the device is both effective and relatively low in cost. The sights may be applied in any suitable position on a boiler or other container in which a view of the interior is desired, and they may be arranged in alternate series, as shown, or in a single column where such arrangement will give sufiiciently satisfactory reading.
Having thus fully described my invention, I claim A hollow casing having varied internal diameters, a reduced screw-threaded inner:
end, a squared outer surface, and being. internally screw-threaded at its outer end, in
' combination with a glass body member having a reduced end and a tapered portion at approximately its longitudinal center, said body being adapted to fit one 01"? said internal diameters; a rubber ring having a tapered inner surface adapted to fit over and engage the tapered portion of said body and its outer surface adapted to engage another of said lnternal diameters; and a retaining ring, externally screw-threaded for engagement With the threaded portion of the casing and adapted to bear against said rubber ring and to retain said glass body in position in the casing.
In testimony whereof I affix my signature.
JOHN J. DALY.
