CALVIN WOODVABD AND GEO. M. VOODVARD, OF NEV YORK, N. Y.
FEED-WATER APPARATUS FOR STEAM-BOITIERS.
Specification of Letters Patent No. 27,853, dated April 10, 1860.
To all whom it may concern:
Be it known that we, C. VooDwARD and G. M. VooDwARD, of No. 77 Beekman street, in the city, county, and State of New York, have invented a new and Improved Boiler- Feeder; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, which represents a longitudinal vertical central section of this invention.
Automatic bolier feeders as a general thing consist of a steam tight jacket which is placed on the level of the mean water line, and which communicates with the steam space, and also with the water space of the boiler, so that the pressure existing in the interior of the jacket, is equal to the pressure in the boiler, and that'water introduced into said jacket flows into the boiler by its own gravity, whenever the water in the boiler sinks below the mean water line. Various devices are employed to introduce water into the jacket, but they are either too complicated and too expensive to give satisfaction or when simple, they are so constructed that it is very difficult to keep the joints tight, and the boiler feeder becomes a source of continuous trouble. A good device of this kind must be so constructed that its effect is certain, that it needs no attention, after it has once been properly adjusted, and that the pump can be dispensed with altogether. Such is our boiler.
To enable those skilled in the art to make and use our invention, we will proceed to describe its construction and operation with reference to the drawing.
A represents a box or tank, made air and water tight, and it communicates by means of a tube a, with the well, from which the water is supplied to the boiler. Secured in the interior of this box is the steam jacket B, which communicates with the steam space of the boiler by means of a tube t, and with the water space by means of a tube 0, and which is placed on a level with the mean water line of the boiler. This steam jacket consists simply of a cast iron tube bored out smooth and furnished with an annular recess or chamber d, in its center, and its edges are turned down perfectly square. C, is the cylinder which fits nicely into said jacket, being retained in the same by means of nuts e,
which screw up steam tight against the edges of the acket. The interior of this cylinder is perfectly smooth, and it is open at both ends. Three pistons D, E, F which are secured to a common piston rod Gr, at equal distances from each other, work steam tight in said cylinder, and the piston rod connects by means of a connection rod f, with an eccentric wrist pin g, on a disk lz, to which a rotary motion is imparted from some part of the engine, or by any other desirable means.
The cylinder O, is perforated with three rows of apertures i, y', and 7c, the apertures i, and c, being outside of the steam jacket so that they form a communication between the interior of the cylinder and the water box A, and the apertures j, being in the middle of the cylinder so as to form a communication between the annular chamber d, of the steam jacket and the interior of the cylinder.
The apertures z', j, and le, are in such relation to the pistons D, E, F that if the latter are moved to their extreme positionin the direction of arrow 1, the holes z', admit water to the space between the pistons D and E, and the water which may be contained in the space between the pistons E and F, passes off into the annular chamber d, and from thence into the boiler if the water in the latter has sunk below the mean water line. If the pistons are now moved in the direction of arrow 2, until the piston F, comes beyond the apertures 70 the space between the pistons E and F, fills with water, and the water contained in the space between the pistons D and E, discharges through the apertures j,.into the annular chamber cl, and from thence into the boiler if the water in the latter is below the mean water line. The water in the boiler, will thus be supplied as it evaporates, and all foaming and priming will be prevented, and at the same time the water displaced from the air tight water box A, will supply itself. For whenever some portion of the same is displaced by the action of the pistons, the pressure of the atmosphere on the surface of the water in the well or tank, will cause the box to fill up again. Our pistons are fur nished with ring packing which adjusts itself if the interior of the cylinder wears. Thus our boiler feeder takes the place of the pump and at the same time it keeps up the proper supply of Water in the boiler perforated cylinder C, and jacket B, as and Without requiring any further attention. for the purpose herein shown and described. A
Having thus described our invention, What CALVIN VVOODVVARD. We claim as new and desire to secure by Let- GEO. M. WOODWARD. 5 ters Patent, is, Witnesses: L
The arrangement and combination of the J. F. BUCKLEY, three pistons D, E, F, and rod Gr, With the W. HAUFF. j
