VALVE.

will enable others skilled in the art to which it appertains to malte and use the same.

rhis invention pertains to improvements in valves. lt relates more particularly to a liest-valve 'for use in connection with tanlr to be supplied with a liquid.

@ne et the objects or' the invention is the provision ci a valve tor use with a float chamber or tank for lowl steam pressure worl-z, such, for example, as used for steamstoiage battery jars, although said valve may be adapted 'for other uses as well.

Another object is to so construct a floatvalve whose valve-seat may be renewed without removing the valve casing from the chamber or tank to which it is attached, and whereby, also, the valve-seat may be adjusted from outside the tanlr without detaching the structure from said tank.

Other advantages and objects will appear herein aided by the accompanying drawing which illustrates the invention in its preferred form, though it is to be understood that slight changes may be made without departing from the spirit and intent of saidv invention.

Figure l is a longitudinal sectional ration of my valve and part of a tanlr or vessel to which it is attached.

Figure 2 is a plan of a plunger or valve showing part of an adjustable member forming` a valve-seat in longitudinal section on a much larger scale than in Figure l.

Figure 3 is an end elevation of part of the structure shown in .Figure l.

Figure 4: is anend elevation oi' part of the structure also shown in Figure L and Figures and 6 are end elevations of dittlierent Jforms or valves.

My purpose is to construct a so called floatvalve particularly adapted for use on a closed tank or vessel. or such as is employed wherein to Create steam niessure, but adapted also tor open tanlis ior various purposes.

it has been necessary in many casesa to remove the entire valve casing from the tank with which it is connected in order to yn n is .cerig ne e construction and relation oi l 'the device.

in my ang-eme i removal is entirely obviated by constructing jt throughout tha thereof at its fd appear;
