CARL HERMANN STAMER, OF HAMBURG, GERMAN Y.

WATER-GAGE.

SPECIFICATION forming part of Letters Patent No. 442,465, dated December 9, 1890.

Application filed June 3, 1890. Serial No. 354,151. (No model.) Patented in Germany March 26, 1889, No. 52,472, and in England June 22,18B9,N0. 10,220.

To LZ tof/tom it may concern;

Be it known that l, CARL HERMANN STAMER, a subject of the German Emperor, and a resident of l lamburg, in the German Empire, have invented certain new and useful Improvements in Valves and Tater-Gages, (for which I have secured .Letters Patent in England, No 10,220, dated June 22, 41889, and in Germany, No. 52,472, dated March 2G, 1885),) of which the following is a specification.

My invention relates to improvements in valves and water-gages, and the objects ot' the same are to provide suitable closing devices for lifting-valves, such as plug-valves, and efficient contrivanees for causing in watergages the steam and water to be instantaneously and automatically shut off when the glass bursts, and allowing' the closing of the automatically-actin g valves to be with facility obviated while blowing the steam through the glass tube for cleansing purposes. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l illustrates a vertical section of a Water-gage constructed according to my invention, and showing, as an example, my improved closing device adapted for use in any kind of lifting or plug valves. Fig. 2 is ahorizontal section on the line Il Il, and Fig. 3 a horizontal section on the line III HI of the upper part of my improved water-gage, Fig. l illustrating the arrangement of the steampassages to permit the communication of the socket connected to the boiler with the gageglass, while Fig. 4 represents a horizontal section on the line IUI IHI, Fig. l, ofthe lower part of my improved water-gage.

Similarletters refer to si mi lar pa rts th roughout the several views.

The main part of my invention relates to the novel method by which an enduring tight closingof the valves is insured, and this is performed by the employment ot' aplng tot soft copper or other soft metal, the sharp-edged face ot' which is adapted to establish a tight closing in the conical seat a of the passage of the tiuid in the valve-casing.- This copper plug tapers toward its free extremity, in order to allow its tight fit inthe conical seat a to be re-established, when necessary, by renewing its sharp circular edge. As the conical form of the plug diii'ers from that of its seat in the val ve-casing, and as, further, the renewal of the sharp edge of the plug can easily be effected by turning or filing oit the hollow face of the conical plug, the renewed circular edge of the latter, on account of its diameter being larger than that of the eut-oit worn edge, will consequently meet a new untouched closing-surface in the corresponding seat a, and therefore an enduring tight fitting of the plug in its seat is insured. rlhis closing device is particularly applicable for water-gages and gage-cocks of the style illustrated in the drawings. The upper part of the water-gage, Figs. l. to 3, consists of a easing g, having attached to its rear side the socket-piece k with iiange 7.1 or a suitable screw-plug, and to its front,opposite to the socket-piece if, the cleaning-aperture, which is closed by the screwplug o. The valve-spindle s, adjustable by means of a screw-thread so in the nut m, and tightened outwardly through the stuing-box p, is provided so as to traverse the cleaning device at an angle of about thirty degrees. To the internal extremity of the spindle s is connected the above-described plug-valve t of soft copper or other soft metal, which iits in the conic bore (l of the passage to the steamgenerator. Sidewise oi' the socket 7e is provided thc tube-inutile r, and in front of the latter the valve-chamber if, communicating through the passage d with the casing g and through the passage c with the tubc-mutiier, thereby allowing the steam to flow through the upper part of the water-gage to the gageglass, in the direction indicated bythe arrows. The valve-chamber r is provided between the aperture d and passage c with a partition L", having a bore or opening a', tightly closed by means of the sharp-edged copper plug t', which is guided by aid of its stem in the closin g-serew j", and adapted to be taken out therewith for cleaning or other purposes.

lYhen the gage-glass bursts, the steam, rushing through the casing g, causes the valve t to be instantaneously closed, while, in order toobviate the closing of the valve when the steam blows through the glass-tube for cleaning the same, the screw-spindle g', provided TOO in the upper part ol' the valve chamber, is slightly turned, thereby arresting' the copper plug` t.

The automatic closing of the lower part of the water-gage, which part is of the saine construction with the analogous portion of the up' per part, except that the. chamber g is in direct communication through the passage (Z2 with the respective tube-Inutile yr and the valve-chamber e omitted, is effected by means of the copper plug` t2, which is adapted to [it in a bore or openingi e2 of a passage in the inuffle 1", and is guided either in the bow of a closing-screwf, as the plug-t in the upper part of the water-gage, or in a branch f', of the casingot` thelowerdelivery-valve 71,. The tight closing of the latter, which being', for sake of elearness, represented as turned for ninety degrees, is likewise insured by means of a copper plug t3, provided on the valvespindle s and extending into a conic bore CL3 ot the casing. f

Having,` now fully described my invention,

what I claim, and desire to secure by Letters Patent, is-

As an improvement in water-gages, the casing having a socket-piece 7c, a lower passageway connecting with said socket-piece, an upper passage c, and a diaphragm having` a bore or opening, the valve-chamber n, the vertically-disposed valve having a tapering end designed to fit said bore or opening", the screw -spindle g', designed to engage said valve, and the horizontally-disposed valve titting` a conical seat in the passage from said socket-piece, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 29th day of April, i890.
