IMPROVEMENT IN WATER-LEVEL DETECTOR FOR BOILERS.
awo-
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it ma/y concern:
Atilated float, and
Figure 2 a sectional elevation of the same,
at right angles to iig. l.
Figure 3 is a transverse section through a; x in iig. 2.
Similar letters of reference indicate corresponding parts.
This, our invention, relates to a combination of means or devices, arranged for the most part outside of the boiler, for operation in conection with or by a float, (preferably of a ventilated character,) situated within the boiler, or said devices and lloat may be combined with a box or case in connection with the boiler, the same in either case being of such a character, and so disposed or arranged, as to indicate, by a steam-whistle or alarm, with every facility for adjustment, either the too high or too low level of the water in the boiler; also, when the boiler requires a fresh feed or supply of water, to automatically open the connection between the supply-pipe and the pump.
Our invention, in this connection, consists in a combination, with the stem or plug of the device operated bythe ioat, of a cam-disk valve of the whistle, with its stem and spring applied to the latter, whereby the action of the apparatus or device is perfected, and every facility afforded for varying the period of opening the valver to sound the alarm, and otherwise adjusting its action relatively to the float.
Referring to the accompanying drawing, A represents theone head or end of a boiler, and B a hollow lioat arranged therein, and connected by a tubular stem or rod with a hollow elbow-lever or angular arm, O, screwed on to or made fast, within the boiler, to the operating-stem D ofthe device or apparatus, arranged to occupy a horizontal position, and at liberty to turn on its axis in the barrel or socket E, which latter is of tapering character or construction, to accommodate a taper swell in or to the stem, that makes of the latter a plug or v alve, said tapering barrel or socket being screwed at its smaller end into the head of the boiler, so that steam acting from the inside of the boiler against the stem or plug will have a tendency to relieve or release said plug from sticking in the barrel.
On the outer and large end of the barrel E is a bridge, a, carrying a set-screw, G, with lock-nut, b, for tightening up and holding at its set the plug lD, by bearing against theouter end thereof. This stem or' plug and set-screw G' have an axial aperture them, through which is closely fitted or inserted a small tube, H, open at its ends, and connecting the hollow setscrevv (the-aperture in which is virtually an extension of the tube H) with the hollow elbow-lever or arm C, for the purpose of carrying oli" or allowing to escape vapor formed by leakage of steam or water through the iloat B. This constitutes a simple and compact means for establishing the ventilated character to the float, being all contained as it were within the device controlling the feed, and indicating the too high or too low level of water Vwithin the boiler.
The plug D is cut away, or has a suitable passage, c, made in it, which, excepting when the water has fallen below its proper level in the boiler, or thereabouts, remains under cover ofthe barrel, so as to place the plug in a closed condition, but which, when the plug is turned vby the oat in falling, as thewater gets down to or below its proper level, opens or establishes communication between side branches or tubular connections, I a'nd J, to or from the barrel E, the one of which branches is designed to connect with a water-supply pipe from any suitable source, and the other with the feed-pump to the boiler, so that when the float has fallen, as specified, feed takes place, but stops and remains shut olf when suliioient'water has been pumped into the boiler. This action taking place frequently, keeps the whole device in perfect working order. I
Made fast, in an adjustable manner, on the outer end of thestem or plug D, is a' two-horned cam, K, which, as the plug is turned by the action of the ioat, whether it be from the water in the boiler falling too low, or rising unduly high, serves to depress a horizontal disk, L, connected with a valve, d, of a steami whistle, M, that, on said valve being opened by the depression of the disk L, through either horn, e e', 4of the cam K, admits steam drawn or supplied by asuitable pipe-connection from the steam-chest ofthe boiler, or other source out of the reach of the water, to sound the whistle. lVhere the detector is only required to indicate the too low level of the water in the boiler, then one horn, (e or e) will suiice. p
In working, or when pressure is on, the steam from the boiler will keep this valve d closed, while, prior to getting up steam, a spring, j, round the valve-stem accomplishes the same, that is, in both cases, excepting when the horns c e of thegcam K operate on the disk L to open the valve.
This disk L is preferably of 'a convex or other equivaient form on its upper face, to secure a quicker open-g ing movement to the valve of the whistle by the action of either horn e e on said disk L, which latter is adjustable by o set-screw, g, up or down the stem of the valve, so as to vary the period of opening the valve d by the action of the fioztt to suit circu1nstauces. The adjustment of the cam K on or around the outer end of the stem or plug D by set-screws h is foi` the purpose of adjusting the horns e e in proper relationship to theoam L, to meet Variations in the altered conditions of the ioat.
Vhat is here claimed, and desired'to be secured by Letters Pat-ent, is
The combination, with the stein or plug D, of the com K, disk L, the valve (Z of the Whistle with its stem zuid the sp1-ing f, as described.
