BOILER FEEDER AND METER.

SPECIFICATION forming part of Letters Patent No. 450,902, dated April 21, 1891.

Application filed September 3, 1890. Serial No. 363,802. (No model.)

To aZZ whom it may concern:

Be it known that 1, JOHN E. WINDER, of Pacific, in the county of Franklin and State of Missouri, have invented a new andlmproved Boiler Feeder and Meter, of which the following is a full, clear, and exact description.

The invention relates to boiler-feeders such as shown and described in the United States Letters PatentNo. 385,893, granted to me July 10, 1888.

The object of the invention is to provide a new and improved boiler feeder and meter which is simple and durable in construction,

' very effective and auto matic in operation, and

registers the quantity of water used.

The invention consists of aWater-receptacle connected with the boiler and containing a float, a steam-chest connected with the said receptacle and with the boiler, and a valve held in the said steam-chest.

The invention also consists in certain parts and details and combinations of the same as will be described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional'side elevation of the improvement as applied. Fig. 2 is an enlarged sectional side elevation of part of the improvement, and Fig. 3 is a plan view of part of the improvement.

The improved boiler feeder and meter is provided with a Water-receptacle A, into the lower part of which leads awater-supply pipe 13, containing a check-valve B. Opposite this pipe B is arranged a discharge-pipe C, also provided with a check-valve O and connecting the water-receptacle A with the boiler D at any desired point.

In the water-receptacle A is fitted to slide vertically a rod E, the upper end of which extends through a suitable stuffing-box in the upper end of the water-receptacle A. On the lower part of the rod E is secured a float G,

so constructed as to have sufficient buoyancy to sustain its own weight when submerged and exerting its force on the rod E only when the water-receptacle is emptythat is, when the water is below the said float Gr. Near the upper end of the rod E, within the receptacle A, is secured a second float F, which is open at the bottom and acts as a float only when the receptacle A is nearly full of water.

On the outer end of the rod E are formed two lugs E and E adapted to engage a pin H, held on an arm H, mounted to turn loosely on a shaft I, mounted in suitable bearings secured to the top of the water-receptacle A. From the arm H extends a second arm H carrying a weight. The arms H and H form a bell-cram k lever, which is provided with projections J and J, adapted to alternately engage the arm K, secured on shaft I, so as to turn the latter when the bell-crank lever changes its position, as hereinafter more fully described. The arm K is pivotally connected by a link K with the valve-stem L, carrying the ordinary slide-valve N, fitted to slide in the steam-chest 0, supported on top of the receptacle A and connected by a pipe P with the steam-compartment of the boiler D at the water-level. The slide-valve N is adapted to operate over the ports a and Z), of which the latter is an exhaust-port and leads to the outside, while the port a connects with the pipe Q, extending into the receptacle A and carrying in a short branch pipe near its upper end a check-valve R. The lower end of the pipe Q, is formed into a horizontally-extending coil S, similar in construction to the coil shown in the patent above referred to and for the same purpose. The coil S is about in line with the pipes B and C. From the bottom of the receptacle Aleads a blow-off pipe T, constructed in the usual manner.

The arm K previously mentioned is connected by a pawl U with a ratchet-wheel V of the meter or registering device V, arranged on the top of the receptacle A. This meter V has the ratchet-wheel V, secured on a shaft V mounted to turn in the casing of the indicator and carrying at its front end a pointer V indicating on dial V. A dog V is held on the casing of the indicator and engages the ratchet-wheel V to prevent a return movement of the latter. hen the arm K swings from the left to the right, the pawl U shifts the ratchet-wheel so that the shaft V is turned, and the pointer V 'moves to the next graduation on the dial V*. This movement of the arm K takes place every time the receptacle fills with water, and as the cubic coir tents of the receptacle A are known a full registration of the entire amount of water taken into the receptacle is indicated on the register or meter V.

The operation of the feeder is as follows: When the slide-valve N is in the position shown in the drawings, the pipe Q is connected by the ports a and b with the outside, and the steam from the boiler D is shut off from the receptacle A. As the check-valve B in the water supply pipe B is free to open, the water enters the receptacle and fills the same, the check-valve C being closed by the boiler-pressure, while the check-valve R opens to let out the air in the upper part of the receptacle A. WVhen the receptacleA is nearly filled with water, the float F rises and moves the rod E in an upward direction, so that the lug E, acting on the pin H of the arm H, swings the latter, so that the weighted arm H passes beyond the vertical position and is then thrown downward quickly by the weight, whereby the lug J, acting on the arm K, swings the latter to the right, thereby shifting the valve Nso that the port a is opened while the port Z) is closed. This movement of the lever K actuates the pointer V on the dial, as previously described, so that the amount of water admitted to the receptacle A is registered. The steam from the boiler D can now pass through the pipe P, through the steam-chest 0 into the port a, and from the latter to the pipe Q to close the check-valve R and to pass through the coil of pipe S in and through the water in the receptacle A to heat the same. The pressure in the receptacle A will now be equal to the boiler-pressure, so that the check-valve B closes and the water-supply is shutoff, and at the same time the check-valve 0 opens by the weight of the water contained in the receptacle A, so that whenever the water in the boiler is lower than pipe P, which enters the boiler at a predetermined water-level, the water in feeder will seek a levelin the boiler until said pipe P shall be covered or the proper level reached. When the water in the receptacle A is nearly all discharged, the float G is uncovered and by its weight draws the rod E downward, so that the upper lug E acts 011 the pin H to swing the arm H downward. This movement of the arm H causes the arm H to swing until it finally passes a vertical position, after which the Weight suddenly throws the arm H downward to the right, so that the projection J strikes the arm K, thus turning the same to the left, and thereby shifting the slide-valve N to the position shown in the drawings. The steam from the boiler D passing through the pipe P is now shut off, so that the check-valve C closes, the valve B in the supply-pipe B opens, the receptacle A is again filled with water, and the above-described operation is repeated.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. In aboiler-feeder,thc combination, with a water-receptacle connected with the boiler, a steam-chest connected with the receptacle and the boiler, and a valve in the steamchest, of a float -carrying rod mounted to slide in the receptacle and provided with lugs on its projecting end, a shaft provided with a crank-arm connected with the said valve, and a bell-cranklever loosely mounted 011 the shaft and provided with projections for engaging the crank-arm, one of the arms of the bell-crank lever being weighted and the other engaging the end of the float-rod, substantially as herein shown and described.

2. In a boiler-feeder, the combination, with a water-receptacle connected to the boiler and provided with a coil in its lower portion, a steam-chest connected with the boiler and the said coil, and a slide-valve in the steamchest, of a vertically-sliding rod in the receptacle and provided with lugs on its projecting end, two floats on the said rod, a shaft provided with a crank-arm connected to the slide-valve, and a bell-crank lever loosely mounted on the shaft and provided with proj ections for engaging the crank-arm to move it, one of the arms of the bell-crank lever being weighted and the other engaging the end of the sliding rod, substantially as herein shown and described.

8. In aboiler-feeder, the combination, with a water-receptacle connected with the boiler, a steam-chest connected with the receptacle and boiler, a valve in the steam-chest, and a float-carrying rod mounted to slide in the receptacle and provided with lugs on its proj ecting end, of a shaft provided with a crankarm connected with the said valve, a weighted bell-crank lever mounted loosely on the shaft and provided with a projection for engaging the crank-arm, a registering device, and means for operating the registering device from the crank-arm, substantially as herein shown and described.
