Description

V. A. LANG. GAGE COCK.
APPLICATION FILED SUNE 3, I913- Patenred June 13, 1916.
INVE/VTUR VM M 4. l -5 BY ATTOR/VEN.
' gine for the VICTOR A. LANG, OF HOUSTON, TEXAS GAGE-COCK.
To all whom it may concern: 7
Be it known that I, VICTOR A. LANG, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain newand useful Improvements in Gage-Cocks, of which a the following is a specification. This invention relates to new and useful improvements in gage cocks.
The object of the invention is to provide a device of the character described to be used in connection with the boiler of an enpurpose of determining the amount of water in said boiler and consists of a simple, inexpensive and elfective device designed to be used for the purpose indicated.
With the above and other objects in view,
the invention has particular relation to certain novel features off construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 is a sectional side elevation of the device. Fig. 2 is a plan view of the connection by means of which the device is connected to a water column. Referring now particularlyto the drawings numeral 7 indicates a cylindrical casing, formed usually of brass and separated into two chambers 8 and 9 by means of the valve seat 10 having the diverging'opening 11 therethrough. From the chamber9leads the spout 12. The casing 7 is secured to the water. column not shown by means of a connection 13, the outerend of which is threaded for enga ement in a tapped hole through the wall of the water column and the inner' end of which has a reduced outwardly threaded nipple 14 upon which the casing 7.
is screwed.
A-valve stem 15 is provided upon which is fixed the valve 16, which conforms in shape to and controls the passageway 11 of the seat 10. This valve stem slides through the bearings 17 and 17', the former of which is carried by the connection 13 and the latter of which is carried by the opposite end of the casing 7.
Specification 2f Ltterslatent.
Application filed June 3, 1913. Serial No. 771,428
through the a said casing intermediate its ends,
' Patented June 13, 1916.
Surrounding the valve stem and interposed between the connection 13 and the valve 16 is a coil spring 18 which normally holds the valve 16 firmly seated and prevents the escape of any steam or water seat 10.
Pivoted to the outer end of the casing 7 ls the lever 19 depending from which is the arm 20 which normally rests against the outer end of the valve stem 15. When it is desired to open the valve 16, the lever 19 may be pressed downwardly which will impart an inward movement to the valve stem 15 through the arm 20 overcoming the pressure of the spring 18. Water, or steam, as the case'may be, is thus permitted to pass through the seat 10 and is discharged through the spout 1 In actual use the operation of the device is as follows: a water level in a boiler may be determined by a downward pressure on the lever 19. If when said lever is depressed steam is emitted from the spout 12, it will be apparent that the water level in the boiler is below the gage opening, and the amount of water in the boiler can be quickly approximated.
What I claim is A device of the class described compris ing a cylindrical casing having one end open, its opposite outer end provided with a central opening, a wall formed interiorly of a tapered valve seat 'centrally -in said wall, a plug fitted in the open end of' said casing, and provided with a central opening in direct alinement with the tapered valve seat and the opening in the outer end, said wall dividing the casing into inner and outer comface of the valve and normally'holding said casing, a valve formed valve ,in engagement with the valve seat, name to this specificationin the presence of and afleverl' pivotally connected tot the ogllter tw'o subscribing Witnesses. end 0 sai valve casing, an arm orme on said lever and extending laterally therefrom VICTOR LANGT and adapted tolengage the terminal end of WVitnesses: the valve stem for unseating said valve. J. W. YEAGLEY,
In testimony whereof I have signed my MAY MONTGOMERY.
