` i `The1 Schedule in these Letters Patent andmaklng peut of the-same.
i I, Hman! KIMBALL,y of Randolph, inthe county of Orange and Stateof Vermont, have invented certain Improvements'in `Imw-water Indicators for Boilers, of -which the ,followingis a {specification} l L l Natura liects `ofthefIm:cnt/ion. 1 My invention rclatesdn vpart to animprovement on that patented` to,medunel,1869,.,which consists essentially of a water-chamber or reservoir, located ex'- Iternally of the boilerabove the water-line, and communicating with thefin'terior of the boiler througha `pipaat thelowest level to which theuvater inthe 1 boiler isdesired'to fall before an alarm-is sounded.
` y The "elevated chambenlcontains a buoy, to the'np-` y per partof whicliis1 attached a valve closing a port `communicating"with the 1atmosphere,"so that, so long as `the water in .the boiler is at a proper height, the
` 3pressure` of steam` keepingtheelevated chamber or reservoir full of water` will 'cause theI valve to be Ipressed against its seat;` but the instant the water de- Y scenfds below the month of the pipe leading from the rescrvoirintothe Vlioilerytlle water will run from the elevated reservoir,"its' place being supplied "with steam l andpermitting'thelbuoy to descend by its gravity, so
, opened and 'steam discharged` therethrough, soundiingia whistle orother alarm until the boiler receives afproper supply of water. l Q
a Myfpreset improvementsl` consist-1` First, in aicombination and `a'rran'gement of parts whereby themovementof the valve is rendered more `certainanddelicate,laudthe valve beingI guided to `andffrom its seat in a perfectly rectilinearpath, will,
` be preservedfrom liability1 to unequal wear. i

Figure y5 isa horizontalsection'at z z, figs. land 3. `Figure 6is` atLaXal section of `the valve-chamber,
` "showing the valvepartlyin` section, and illustrating the manner ofgrindin'g into its seat. l Genera-l` Description, t Havingthe elevated reservoirfgvbuoy B, valve E,.
i 8vo., as before referred to, I connect the upper part of said-elevated reservoir A, with the steam-dome or any part' of theboiler, which,` being above'the water-level, i is alwaysoccnpied by steam by means of a small pipe,
F, provided with a stop-cock or valve, I, which ordi- -uarilyremains closed.
f Now, it willbe readily seen that lon 4the stop-cook or valve I being opened, steam'will enter the upper part of the reservoir, produce 'au equilibrium of pressure, and 'allow the water in the reservoirto fall to the'same level asin the boiler, andproduce the same action of the'bnoy B and valve E as thongh'the )vater in the boiler had"fallen so low as 'to allow the elevated reservoir to be filled with steam through themain pipe H. This device thus affords an almost instantaneous test of the action of the indicator. y,
The pipe E serves not'only asa test-pipe, but also to keepthe indicator in order by allowing the water in the' elevated reservoir to'fall quickly, and, if necessary,vii'equently, whereby any scale` or otherA refuse which might otherwise lodge in the indicator will be washed out; and in case of anything lodging between the valve E and seat S, so as to prevent the valve E from closing, `opening the Ytest-pipe F` will cause the valve E to fall, and allow the impediment to drop or pass out with the steam, whereas without the testpipe this actioncan only be produced by allowing the 'waterin the boiler to fall below the month oi' the pipe'H.
In order to facilitate the cleaning of the valve and y grinding it into its seat when necessary, the valvechamber Q is made' removable by means of a screwcoupling, q, and the valve Elconnected to its stem R by a socket-joint and pin, L.
In case of the valve vbecoming,leaky, it is only necessary to screw out the valve-chamber Q and remove the pin ,L, when the valveE can be taken out and its seat'may be readily cleansed, and, if necessary,
ground in by inserting atapered stick or handle,
T, in the aperture t, which fits over the valve-stem R. v Any necessity of removing the entire 'apparatus from the boiler for'the purpose of retting the valve is. thus entirely avoided, and hence the fitting or cleaning of the valve can be accomplished as often as ,required with a trilling expenditure of time or labor.
This, and other improvements herein described, are severally applicable to various other forms caters or. alarms for steam-generators.
In order to obtain an action sufficiently powerful to Vbe reliable by the'use of only a small buoy, I employ the arrangement shown clearly in section in figs. l, 2. and 3, to obtain a powerful leverage in the action of y 'the buoy on the valve.
The reservoir being constructed with a small extension on one side, as shown in the drawing, the buoy B .is provided with -an arm, O, which plays on a piu or pivot, D.
The valve E is connected with the arm C by any device that will'allow the necessary movement of the of indi- V joint as the arm .C swings on the pivot D, the valve Claimsbeing held in line with its seat by the guides G G. A I claim as my inventionpreferred form of joint is shown in gs. 3 and 4. 1. The elevated reservoir A, connecting-pipe H,
