VILLIAM P. (HURRY, OF VINCENNES, INDIANA.
FEED-WATER APPARATUS FOR STEAM-BOILERS.
Specification of Letters Patent No. 25,811, dated October 18, 1859.
To aZZ whom 'it may concern:
Be it known that I, WILLIAM P. CUERY, of Vincennes, in the county of Knox and State of Indiana, have invented a new and Improved Boiler-Feed; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, making a part of this specification, in which- Figure 1 represents a front view of a boiler with my invention. Fig. 2 is a longitudinal central section of the valve in a larger scale.
Similar letters of reference in both views indicate corresponding parts.
The object of my invention is to obviate the injurious influence on the regularity of the feed caused by the spring of the rods which connect the float in the boiler with the stop-cock or valve in the feed pipe; and my invention consists in employing for the connection between the float in the boiler and between the stop-valve in the feed pipe double rods in such a manner that one of the rods always pulls as well when the float rises as when it sinks down and that the slightest motion of the float affects the valve no matter what the distance between said valve and the boiler.
To enable those skilled in the art to make and use by improvement I will proceed to describe its construction and operation.
A represents a steam-boiler of such a construction that it will admit the use of a float in its interior. The float, B, has its stern, a, rigidly attached to an arbor, Z), that extends through the head of the boiler. This arbor bears a disk, o, which has two studs, cZ, eZ', fastened in its side, one opposite the other, and on the same diameter of the disk. A similar disk, e, is secured to one end of an arbor, f, that has its bearings in a standard, C, which is secured to a beam, F, or to the ceilingA of the boiler room, or in some convenient position. The other end of the arbor, f, bears an indeXehand, D, that travels over a dial plate, E, which is marked with appropriate marks for the purpose of determining the height of the water in the boiler.
The disk, e, has four studs, g g' and Zt h', secured in its side at equal distance from its center and so that the same divide a circle drawn through their centers in four equal parts. The studs, g g', connect by rods, Gr
G, with the studs, eZ CZ', on the disk, o, and the studs, Zz 71,', connect by means of rods, H H', with studs, c', z", on a disk, 7c, that turns on a pivot, 7c', secured to a standard, C', in a convenient position on the beam, F. Two more studs, y' j', are secured in the side of the disk, Z0, so that the four studs, z' i' and j j', divide a circle drawn through their centers in four equal parts in the same manner as the studs, g g and L ZL', on the disk, e.
The studs, y' y', on the disk, Za, connect by means of rods, I I', with studs Z Z', on a disk, m, that is secured to the stem of the` stop-valve, K, or the cock through which water is admitted to the feed pipe.
The most convenient valves for my purpose are those constructed as shown in Fig. 2. A disk, a, with a series of holes, 0, works on a seat, p, with a corresponding number of holes, g. When the disk is turned so that the holes, o, register with the holes, g, in the seat, the water passes through. It will be noticed that it requires but a slight amount of motion to close such a valve and to open it, and it can also be constructed so as to work tight without creating an undue friction.
If the float B, in the boiler rises, the disk, c, turns in the direction of the arrow marked thereon, and it causes the rod, G, to exert a strain in the direction of arrow 2, whereby the disk, e, is turned in the direction of the arrow marked o'n it. The index-hand, D, therefore points higher when the water rises in the boiler, and lower as it sinks down.
From the disk, c, the motion is transmitted by the rod, I-I, which pulls in the direction of arrow 3, to the disk, Ze, causing the same to turn in the direction of the arrow marked on it, whereby the rod, I, is caused to draw in the direction of arrow 4, and the stop-Valve is closed. When the float sinks down the motion is transmitted through the rods, G', H and I, to the stop valve, which latter opens so as to admit more water to the boiler.
It will be noticed that in each case the rods, which transmit the motion of the float,
pull, so that no spring takes place, whereby the correct operation of the stop-valve may be disturbed, and so that the distance of the stop-valve from the boiler, no matter how great it be, is of no consequence.
Having thus fully described my invenvalve, K, substantially as and for the purtion what I claim as new, and desire to sepose described. cure by Letters Patent, s:-
The arrangement of the rods, G G', H H', WM P' CURRY' 5 I I', or their equivalents to operate in com- Witnesses:
bi'nation with the disks, z' e, la, m, or their GEO. W. DUNN, equivalents, and With the float, B, and stop- F. W. VIEHE.
