ALVIN W. VANDORSTON, OF SALEM, OREGON.
IMPROVEMENT IN HIGH AND LOW WATER INDICATORS FOR STEAM-BOILERS.
Specification forming part of Letters Patent N 0. 199,598, dated January 22, 1878; application filed February 17, 1877.
To all whom'z't may concern:
Be it known that I, ALVIN W. VANDORSTON,
' of Salem, in the county of Marion and State ters of reference marked thereon, which form a part of this specification, and in which Figure 1 represents a front elevation of a Water-gage and alarm embodying myimprovements. Fig. 2 represents a side view of the same in partial section, and Fig. 3 "represents a detail view.
Similar letters of reference occurring on the several figures indicate like parts.
My invention relates to improvements in water-gage and alarm for steam-boilers; and it consists in the details of construction, and general arrangement and combination of parts, all as will be hereinafter more fully described, and pointed out in the claims.
Referring to the drawings, I represents a cylindrical chamber, having pipes J for connection with the steam-boiler, and provided with a steam-gage, A, and try-cocks H, as shown. At the upper end of this chamber 1, and to one side of the pipe J, is formed a chamber, L, having a closely-fitting cap, G, at one side, provided with a journal-bearing in the center, for the reception of one end of the rod K, which passes through the chamber L to the water-gage B, where it is provided with an indicator-hand for registering the depth of water in the boiler, a cog-wheel, F, and valve 1 being attached to said rod in the interior of the chamber, as shown.
E represents a hollow spherical float adapted to loosely fit in the chamber I, and to the upper part of which is attached a Cogstem, F
which works up and through the chamber L: and connects with and operates the cog-wheel F, as also the rotary valve I. D represents the low-water whistle, having a sharp sound, and O the high-water whistle, having a coarse sound, to distinguish the two apart when my valve I, as shown in Fig. 2.
'In the operation of my invention it will be observed that the float E, rising and falling in the chamber I, operates the cog-wheel F through the medium of the cog-stem F, and that, in turn, operates the rod K, carrying the valve I and indicator-hand of the dial, thereby enabling the height of the water in the boiler to be seen at all times.
It will also be observed that when the water in the boiler is too low or high the] float E, operating the cog-wheel F,. as already described, turns the rod K to a certain point, and with it the valve I, bringing the opening of the same in juxtaposition with the opening leading to the whistles G D, allowing of the escape of the steam and the sounding of an alarm.
Having thus described my invention, I claim as new and useful- 1. The rod K, having attached thereto the wheel F, valve 1, and indicator-hand, in combination with the cap G, provided with a journal-bearing for said rod K, substantially as described.
2. The rod K, having attached thereto the wheel F and valve I, in combination with the float E, cog-stem F, whistles G D, and watergage B, whereby a high and low water. alarm is sounded, and the height of water in the boiler indicated, substantially as described.
ALVIN W. VANDORSTON.
