AUTOMATIC WATERGAGE.
PECPCATON forming part of Letters Patent No. 319,052, dated June 2, 1885.
Application filed August Q1, 1834. (No model.;
To @ZZ whom it may concern.-
Be it known that we, Lnwis C. BAILEY and XV. Scorr ALEXANDER, citizens of the United States, residing at MeGonnellsburg, in the county of Fulton and State of Pennsylvania, have invented a new and useful Improvement in Automatic lVaterGages, of which the following is a specification, reference being had to the accompanying drawings. v
This invention relates to water-gages; and it has for its object to provide a device of this character which will act automatically to close both the water and steam tubes of the gage should the glass indicatingtube be accidentally broken while the boiler is in operation. ln the old form of water-gage if the glass tube be accidentally broken from any cause whatever, the steam and water will be forced out,
so as to scald the engineer or other attendants before they can reach the cocks or valves to close or cut off the connection.
Our invention obviates this mostserious objection, and to this end it consists in certain details of construction and combination of parts, as hereinafter set forth, and particularly pointed out in the claims.
In the accompanying drawings, Figure l is a longitudinal section of the water-gage and a portion of the boiler, illustrating the attachment. Fig. 2 is a detail view ofthe strainer.
Referring to the drawings, A B designate two gage-coeks having their inner ends eXte riorly threaded to screw into suitable open ings at the upper and lower portions of the boiler G, so that said cocks will communicate, respectively, with the steam and water spaces of the saine. The cocksA B have hexagon projections c b on their inner ends forward of the exterior threads to receive a wrench or other instrument in attaching thein to the boiler, and are interiorly threaded at E E to receive the threaded ends of thinibles F F', the latter, F', having a cylindricalshaped strainer, C, formed therewith and projecting through the water of the boiler, so as to exclude dirt and other matter from passing into the coclnand yet permit the free circulation of water into the cock B.
The cocks A B are each provided with a longitudinal passage, D, extending through the saine from the inner to the outer end, and a transverse passage, I, extending through extensions H H', projecting, respectively, downward and upward from the cocks A B. The glass tubeJ is attached to the said extensions H H', which are threaded to receive stuffingboXes K K, forming a water and air tight connection therein. lt will be seen thatthe longitudinal passages D and transverse passages I form a means of communication with the glass indicating-tube, so that the water from the boiler will enter the passageD of the cock B, pass through the transverse passage I, and enter the glass tube to show the true depth of water in the boiler.
Arranged within the passages D of the cocks A B at their inner .ends are balls L L, adapted to work in t-he passage, the thimbles F F preventing the balls from passing out into the boiler, pointed lugs M M extending inwardly into the passage D from the sides and at the forward ends thereof, and serving to limit the forward movement of the said balls.
A branch pipe, M', extends downwardly from the cock B, and is provided with avalve or cock, N, through which to draw off the water from the glass tube to prevent freezing when not in use.
0 designates a stein or spindle threaded at one end to screw through the outer ends of the cocks A B, a stuffing-box, l?, being tted over the ends around the stein to preserve a water-tight connection. The inner ends of the stem O are rounded and project forward sufficiently, so that when screwed inward they will force the balls L L backward or inward through the passage D, for the purpose hereinafter explained. The outer ends of the stems O are provided with hand-wheels B for convenience in operation.
Guard-rodsS S, two in number, one of which is not shown, are attached to the outer ends of the cocks A B, and serve to guard the glass tube from breakage.
The operation of our invention will be readily understood'froin the foregoing description, taken in connection with the annexed drawings. The cock A is attached to the upper portion of the boiler, and allows the passage of steam, and the cock B is attached tothe lower portion thereof, and permits the free circ-ulation of water, the glass tube connecting the two cocks in the manner' well knowin As will be seen, 'the water from the boiler passes through theeoek B into the glass tube, so as to showthe true 'depth of water therein, since the balls L L do not interfere with the free passage of water and steam while the boiler is in operation. Should the glass tube be acci- 'dentall y broken,the force of the steam and water will force it into the position shown in dotted lines, Fig. l, the balls closing the outlet of the passage D, and thus preventing the escape of hot water and steam. In this manner a safetygage will be provided which will be automatic in its action to prevent the scald ing of the engineer should the glass tube be accidentally broken while the boiler is in op'v eration. After a new glass tube has been re-y placed, the wheel R is turned to cause the in ner end of the stem O to come in contact with the ballL in the cock B to force it back .a slight distance until the water `fills the glass tube, the same operation being repeated with upper cock, A, to admit steam, when both.v
balls L will assume their natural positions, as seen in full lines, Fig. l.
If at anytime the boiler is` empty and the glass tube is broken, and yet it is desired to n'll the boiler to obtainA asuicient amount ot` steam, it is only necessary to screw the stem O- inward and against the lugs M to close the pas-` sage D and there let it remain, since both .balls will occupy the. position shown in full lines when there is no Water in the boiler. lhenI the boileris filled and in operation, there-Will. be no force on the balls unless the glass tube should be broken. It will be seen that thev4 balls will be allowed to move freelyin thepassages l), the thimblesF Flimiting their movey ment inward, while the pointed lugs -M M pro- Vide' a seat and hold thein from forward movement.

circulation of.water. tothe glass tube. The' balls act automaticallyfto prevent,fupon the breakage of the glass tube, the passage of Water or steam outward to do injury to the attendants, and when the glass tube has been replaced by a new one the stems O are operated to-restore the parts totheir originalpositions- The device is simple in construction, auto` matic inaction, inexpensive to manufacture, and of great utility for the purposes intended. Having described our invention ,We claim ,1. VrThe combination, with the steam and water gage cocks and connecting glass tube, of the herein-described detachable strainer comprising the hollow body open at one end, which 5 1 cock and'securing. theoball-valve therein. and .f
