GAGE-GLASS.

Application led .Tune 16, 1915, Serial No. 34,392.

To all whom z't may concern:

Be it known that I, MICHAEL J. BREEN,

a citizen of the United States, residin`g"at\ Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Gage- Glasses, of which the following is a speelfi- T his invention relates to ployed in connection with steam boilers/to indicate the height of water in the boiler.

The invention has for its object to provide an improved glass tube constructed of wire glass, the embedded wire netting being so arranged that the gage can be easily read.

A further object` of the invention is to provide a novel?! and improved/yidevice for cleaning the tube .without removal from the boiler.

The objects stated are attained by means of a combination and arrangement of parts to be hereinafter described and claimed, and in order that the invention may be better understood, reference is had to the accomdrawing, in which- 1 1s a s1de elevation of a gage 1n accordance wlth the 1npanying Figure glass constructed vention; Fig. 2 is a vertical section of the glass, and Fig. 3 is a horizontal section thereof.

Referring specifically to the drawing, 5 denotes the glass tube of the gage, the same being connected at its ends to the boiler by suitable..metal couplings G and 7, respectively. The top coupling has a stufling box 8 which is in line with the tube and above the upper end thereof. Through this stuffing box a rod 9 passes down into the top coupling, said rod being in alinement with the tube. The rod carries a swab 10 at its lower end designed tok enter the tube for the purpose of removing sediment therefrom. The rod is slidable, and upon pushing it downward, the swab enters the tube and wipes'the same clean on the inside. The rod is long enough so that the swab may be pushed down to the lower end of the tube, and below this end of the tube the bottom coupling 7 has a pocket l1 to receive the sediment brought down by the swab. The

Renewed November 2o, 1917. Serial No. 203,061.

pocket has an outlet for the removal of the sediment, and said outlet is closed by a screw plug 12. The rod 9 is normally in `raised positionl so as to locate the swab 10 in the top coupling 6, thereby leaving the tf rjlass tube 5 entirely unobstructed.

The tube 5 is made of wire glass, the wire ff/netting 13 embedded in the glass having longitudinalopenings in frontJ and at the sides of the tube extending throughout a substantial portion of the length of the tube, thus leaving the tube unobstructed at these places to give a clear view of the water column from different positions. rthese openings are made in the netting before the same is embedded in the glass, and the netting is also painted or enameled red. T his distinctive coloring of the netting forms a back ground for the water column and makes the gage very easy to read. As the netting is embedded in the glass the color remains clear and unsoiled. A glas-s tube reinforced as herein described requires nov metal casing, the wire netting giving suliicient strength to the glass to withstand the pressure.

The preferred embodiment of the invention has been shown but it will be evident that various changes and modifications may be made without departure from the spirit and scope of the invention as claimed hereinafter.

I claim:

The combination with a gage glass, and top and bottom couplings for connection with the boiler; of a slidable rod extending into the top coupling in alinement with the glass and having a swab at its lower end, the bottom coupling ha ving a sediment pocket located beneath the lower end of the glass and inv communication therewith, and having a clean-out opening, said-pocket being an unobstructed chamber of greater width than the diameter ofthe glass, anda closure for the clean-out opening.

In testimony whereof I affix mysignature in presence of two witnesses.

MICHAEL J. BREEN.
