BOILER-FEED.

SPECIFICATION forming part of Letters Patent No. 791,981, dated June 6, 1905.

Application filed September 6, 1904. Serial No, 223,360.

To all whom it may concern.-

Be it known that I, DANIEL Grow, a citizen of the United States, residing at Millville, county of Cumberland, State of New Jersey,

5 have invented a new and useful Boiler-Feed,

of which the following is a specification.

My invention consists of a novel construction of a boiler-feed whereby great safety is obtained.

My invention further consists of novel operating mechanism whereby heated water is intermittently supplied as desired with great regularity.

My invention further consists of novel 5 valve-operating mechanism and lifting and stripping means therefor whereby the intermittent supply of water to the boiler is assured.

My invention further consists of novel features of construction, all as will be herein- 20 after set forth.

Figure 1 is a side elevation and partial vertical section of my feed-water receiver and regulator. Fig. 2 is a view corresponding to Fig. 1, with the operating parts in a dif- 5 ferent position. Fig. 3 is an elevation and partial section of the entire mechanism, including the boiler.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates a boiler having live- steam pipes 2 and 3 and water-pipe 4, connected therewith. 3 and 4 are connected at their other extremities in the top and bottom, respectively, of an intermediate 35 chamber 5, extending above and below the level of permissible water height of water in the boiler, which agrees with the height of water within this chamber 5.

Between ears 6 is pivoted a float-arm 7, car- 4 rying float 8. Intermediate thepivot and float are attached links 9 and 10. Link 9 connects with one end of the bell-crank 11, the other end of which operates rod 12, opening and closing a valve 13 in pipe 13, connected to 45 chamber above the permissible water-level therein. Link is provided with a bifurcated slotted end 14, straddling the float-arm,

in which is located a pin 15, movable in said slotted end. The link 10 at its upper end is connected with a valve 16-, which admits steam at both extremities of this movement to whistle 17 through pipe 18. Connecting-pipe 13 leads through valves 19 and 20 to the bottom of the feed-water regulator 21, and branch 22, having therein valve 23, is provided between points 24 and 25 of pipe 13 in order that greater control of this passage may be maintained and that one of these passages may be opened in case of stoppage of the other.

Valve 19 is operated by lever 26 and link 27, which is pivoted at one end thereto and at the other end to lever-arm 28, which in turn is pivoted at 29 and carries, adjustable upon its length, weight 30. Between weight 30 and pivot 29 the lever 28 passes through an aperture in rod 31, which at its lower end is controlled by a diaphragm (not shown) Within the pressure-operated regulator 32, which is adjusted to open valve 19 when any desired pressure is exceeded. Pressure-regulator 32 is connected at it lower end, by means of pipe 33, with the interior of regulator 21 through gate-valve 34, the gate-rod of which is pierced at 35 to permit passage of the float-lever 36. This lever and also float-lever 37 are pivoted at any suitable point to attachments or projections 38 within the regulator 21. 38 is here shown as a strip or flange extending throughoutthe length of said regulator. Latches 39 and 40 are also pivoted at any suitable point within said regulator. At the upper end of this regulator are shown passages 41 and 42, the former of which contains valve 43, controlling exhaust-steam opening 44 and live-steam opening 45, said valve being operated by valverod 46, which has slot-and-pin connection at 47 to float-lever 36 and is connected to floatlever 37 by a pin 48 and slot 49, which are here shown in 37 and 46, respectively, but which manifestly may be reversed. The passage 42 permits entrance of feed-water through pipe 50, controlled by valves 51 and 52, from feedwater heater 53, which receives its initial sup ply of water through pipe 54, controlled by valve 55. This water is heated in the heater 53 in any suitable manner by exhaust-steam conveyed thereto, as by pipes 56 and 57. A branch 58 leads to exhaust-steam opening 44 and discharge-opening 59. This dischargeopening is controlled by valve-plate 60 upon rod 61, pivoted at its opposite end at 62 upon any suitable part of the frame. This rod 61 is operated by means of link 63, weighted lever 64, rod 65, and pressure-regulator 66 when the pressure within regulator 21, communicated through the passage 68 and pipe 69, exceeds the pressure at which this regulator 66 is set. Live steam is admitted from the boiler to passage 45 through pipe 2.

Latch 40 is provided with a catch 7 O, capable of engaging pin 71 upon rod 46 in the position shown in Fig. 1, and that portion of latch 40 beyond this catch is engageable with pin 72 upon lever37 to release catch with in the limits of movement of lever 37 permitted by the pin and slot 48 and 49 without said lever 37 operating rod 46. Latch 39 is provided in the form shown with a curved end 73 and nose 74, engaging catch 75 in rod 46 in the position shown in Fig. 2. Nose 74 is disengaged from said catch 7 5 by the downward movement of rod 36, carrying pins 76 against curved end 73 of latch 39. Rods 36 and 37 are operated in both directions by floats 77 and 78, which fall by their weight and rise with the water in the regulator in the usual manner.

The operation is as follows, the parts being in the position shown in Fig. 1, in which the feed-water regulator 21 is empty, valves 13 and 20 open, and valves 23, 26, and 34 closed: At the beginning let us consider regulator 21 as filled with the live steam' which had followed up the receding water during the operation from the position of Fig. 2 to that of Fig. 1 before valve 43 dropped and which begins to exhaust as soon as valve 43 opens the port 44 therefor. The water enters through pipe 50, filling up the regulator. The float 77 has a tendency to rise as soon as it is sur rounded by water, but cannot do so beyond the slot limits, owing to latch 40, and remains in the position shown until the water reaches float 7 8 and lifts it sufliciently to release catch 70. Floats 77 and 78 then unite in lifting rod 46, closing the exhaust-steam port, opening the live-steam-admission port, and opening gate-valve 34. Rod 46 is caught in its raised position, Fig. 2, by latch 39. The pressure of live steam in addition to the weight of the water within the regulator 21 is then sufficient to operate pressure-regulator 32 and open valve 19. The pressure-regulator 66 is also operated and closes valve 60. The weight of the water and pressure of live steam together force water through the pipe 13 into receiver 5 and through to the boiler until float 8 rises suflicicntly to close the valve 13 and shut off the flow of water. If this occurs before the waterlevel in regulator 21 has permitted float 77 to drop and release catch 75, the water remains in regulator 21 until valve 13 is again opened by operation of float 8, and the remaining water in regulator 21 is fed into the boiler. The lowering of the water-level below float 78 releases this float, which is, however, maintained in the position with pin 48 in engagement with slot 49 of rod 46 until said rod 46 is released by operation of float 77. When float 77 is permitted to lower by passage of the remaining Water from regulator 21, latch 39 is released from engagement at 74 with rod 47, and the combined weights of floats 77. and 78, rod 46, and valve 43 operate said rod and valve, closing the live steam and opening the exhaust-steam port and closing gate-valve 34. Pressure-regulator 66 now permits valve 60 to be released by adjustable weight 67 from aperture 59, and the position of Fig. 1 is resumed.

It will be evident that various changes may be made by those skilled in the art which will come within the scope of my invention, and I do not, therefore, desire to be limited in every instance to the exact construction herein shown and described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
