WATER-GAGE.

To all whom it may concern:

Be it known that I, I'IENRY C. BURNS, a citizen of the United States, residingat Marshall, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Waterrages, of which the following is a specification.

The present invention relates to certain new and usefulimprovements 1n the construction of water gages such as are commonly employed in connection with steam boilers, and the object of the invention 1s the provision of a gage of this character formed with a tubes and embodying a novel valve mechanism whereby as soon as either of the gage tubes is broken the supply of steam and water is automatically shut off therefrom, tube serving to indicate the level of the water within the boiler while the broken gage tube is being replaced.

The invention further contemplates a water gage which canbe readily applied to an ordinary steam boiler, which is inexpensive in its construction, and which is positive and reliable in its operation. v

Fora full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which;

Figure 1 is a perspective view of a water gage constructed in accordance with the invention; Fig. 2 is a vertical sectional view through the same; Fig. 3 is an enlarged horizontal sectional view on the line 33 of Fig. 2, portions being broken away; Fig. 4 is an enlarged detached perspective view of a pair of the check valves and the stem connecting the same; Fig. 5 is a transverse sectional View through the stem connecting-the check valves.

Corresponding. and like parts are referred to in the followin in all the views 0 description and indicated reference characters.

Specifically describing the present embodiment of the invention, the numeral 1 designates a pipe one end of which is secured to the boiler and communicates with the interior thereof, while the opposite end of the pipe is provided .with a T-cou'pli'ng 2 towhich is connected an upwardly extending pipe 3 and a downwardly extending Specification of Letters Patent.

pipes terminating in the elbows or 2-way connections 5. Threaded in these elbows 5 are thelaterally extending arms 6 which are arranged one above the 0 other and are formed attheir. outer ends with the downwardly extending. heads 7. Each of these heads is formed with a longitudinal bore 7 a communicating at its upper end with the interior of the corresponding 5 lateral arm 6, and also with the transversely disposed bore 6* which intersects the longitudinal bore, the ends of the transverse bore being surrounded by the exteriorly threaded osses. A- valve seat 9 is formed in each of the lateral arms 6 at an intermediate point in the length thereof, and valves 10 are provided for cooperation with these valve seats to shut off the flow of steam and water througlTTa the arms. These valves 10 are formed in connection with valve stems 11 which are threaded in packing boxes 12 applied to the ends of the lateral arms 6. The usual handle 13 is applied to the extremity of each of the valve stems 11 and constitutes a meansfor manually closing the valves 10 to shut off all communication between the heads 7 and the boiler should the latter be found desirable.

Threaded upon each of the bosses 8 is a branch 14 which is'provided at its outer end with a laterally projecting arm 14" and also with a pet cock or blow off valve 15. The branches 14 upon the heads 7 project in cor- 9 0 responding directions and the ends of the corresponding branches are connected by the glass gage tubes 16, the extremities of the said gage tubes being received within packing nuts 17 which are threaded upon the arms 14. Both of the gage tubes 16 are normally in communication with the boiler so as to indicate the level of the water therein, and any scale or sediment which may at any time accumulate within the branches 14 can be readily withdrawn by tem orarily openingthe blow off valves 15. Eac of the branches 14 is formed. at an intermediate point in the length thereof with a valve seat 18 and a check valve 19 is provided operation with each of the valve seats. The two check valves of each ofthe heads 7 are pipe 4, the said connected by a valve stem 20 so as to move In unison, and these valve stems pass throughthe transversely disposed bores 7 110 of the head and are provided with the longitudinally disposed vanes-20. The lower end for 00- a longitudinal axis. This rotation of the check valves tends to prevent the accumulation of scale thereon and also prevents them from sticking upon their seats.

In the operation of the device should either of the gage tubes 16 be broken the water and steam escaping will tend to close the corresponding check valves 19 and to shut off communication between the broken gagetube and the boiler. The uninjured gage tube will then serve to indicate the level of the water within the boiler while the broken gage tube is being replaced by a new tube.

Having thus described theinvention, what is claimed as new is:

1. In a water gage for steam boilers and the like, the combination of a pair of heads in communication with the boiler, a blow off valve for each. of the heads, corresponding branches projecting from the heads, gage tubes fitted between the corresponding branchesor' the heads, a check valve arranged within each of the branches for shutting oii communication between the heads and either of the gage tubes should the said gage tube become broken, and a stem connecting the check valves of the branches projecting from each of the heads, the said stem being constructed to cause a rotary movement of the check valves about their axes when the blow off valve is open. A

2. In a water gage for steam boilers and the like, the combination of a pair of heads in communication with the boiler, a blow oif valve for each of the heads, corresponding branches projecting from the heads and formed with valve seats, gage tubes between the corresponding branches of the heads, check valves adapted to cooperate with the valve seats of the branches to shut off communication between the heads and the gage e .tubes should either of the gage tubes broken,

the said and a valve stem connecting the check valves of the branches of each of the heads, the said valve stems extending through the heads and being formed with longitudinal vanes which are adapted to be acted upon by the escaping steam and water when the blow off valve is open to cause a rotary movement of the'check valves.

3. In a water gage for steam boilers and the like, the combination of a pair of heads in communication with the boiler, a blow off valve for each of the heads, corresponding branches projecting from the heads, a gage tube fitted between the branches, a check.

valve within each of the branches, the said check valves'operating automatically to cut off communication between the heads and the gage tube should the gage tube be broken, and means for causing the check valves to be rotated about their axes when the blow of? valves are open.

4. In a water gage for steam boilers and the like, the combination of a pair of heads, pipes leading to the heads and in communication with the boiler, a manually controlledvalve for each of the pipes, a blow off valve for each of the heads, corresponding branches projecting from the heads and formed with valve seats, blow oii valves for the branches,

ranged within each of the branches for co 'operation with the valve seat thereof, the

said check valves operating automatically to shut oii communication between the heads and either of the gage tubes should either of the gage tubes be broken, and a stem connecting the check valves in the branches projecting from each of the heads to cause check valves to operate in unison, the said stem passing through the head and being formed with vanes adapted to be acted upon by the escaping steam and water when the blow off valve in the head is opened to rotate the check valves about their longitudinal axes.

In testimony whereof I aflix my signature in presence of two witnesses.
