`ROBERT I. ROSS, OF BETHLEHEM, PENNSYLVANIA.
IMPROVEMENT IN GAGE-COCKS FOR STEAM-BOWERS.
Specification forming part of Letters Patent No. 1453693, dated February 17, 1874; application filedl August l, 1873.
To all whom 'it may Gomera:
Be it known that I, ROBERT l. Ross, of Bethlehem, Northampton county, State' of Pennsylvania, have invented an Improved Gage-Cock for Steam-Boilers, of which the following is a specification:
My invention relates to that class of gagecocks in which a weighted lever is caused to force a valve against the end of a steam-nozzle 5 and the object of my improvement is to so dispose of the weighted lever that it shall not be in the wayof the attendant engineer or fireman. l
This object I attain by the combination of a easing, A, having a valve-seat, a, and outlet b at the bottom, a plunger-valve, B, and a Weighted lever, F, hung to the said easing and connected to the valve by a link, H, all as shown in the sectional eleva-tion, Fig. 1, ofthe accompanying drawing. The easing A has a threaded projection, d, at its inner end, to be screwed into the head X of a steam-boiler, and on the said casing is a hollow spherical enlargement, e, communicating with the central passagef, having an outlet-opening, I), at the bottom, and eontainin g a valve-seat, a, to which is adapted a plunger-valve, B. The latter consists, in the present instance, ot' an outer tubular portion, snugly fitted to and arranged to slide within a central passa-ge in the casing, and of a central screw-rod, h, by which the rubber packing/gi, which forms the valve proper, may be adjusted within the said tubular portion. The plunger valve is operated by a weighted lever, .F, having its fulcrum at j, on a stud projecting from the casing, and connected by a link, H, to the said valve, as best observed in the exterior view, Fig. 2, which represents the cock in a position the reverse of that shown in Fig. l.
When the valve is closed, as seen in Fig. 1, the weight at the extremity of the long arm of the lever F is suiiieient to resist the pressure upon the said valve, and to retain the same in its seat, but by simply turning the said lever, which forms a convenient handle, in the direction of the arrow, the valve will be drawn back, and steam or water from the .boiler will escape into the spherical enlarge menti@ of the casing, and thence through the outlet b at the bottom of the same, without inconvenien cin g the attendant. A very slight movement of the weighted lever is sufficient to open the valve, the latter being automatically closed by the same when it is released. The lever is turned to the position shown in Fig. 2, onlyrwhen it is necessary to draw back the valve and hold it open fora time, Nthe weight thus serving to retain the valve in either of its two extreme positions.
In order to take the cock apart, it is only necessary to unscrew the nut 7a from the stud j, when the lever and link H may be detached, and the plunger-valve dra-wn outward from the casing.
I am aware that gagecocks have heretofore been made, in which a guided valve-spindle has been forced by a weighted lever against the end of a steam-nozzle in a casing; I, therefore lay no broad claim to such a device, but limit my claim to such a combination of parts as enables me to so dispose of the weighted lever that it shall not interfere with the engineer or reman by projecting beyond the end of the gage-cock to the extent which detracts from the utility of cocks of this class-that is to say,
I claim- The combination of the .casing A, internal nozzle or seat a, and valve B of a gage-cock, with the weighted lever F hung to the side of the said casin g, and the link H connecting the valve to the lever, all as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
ROBERT I. BOSS.
