UNITED STATES PATENT OFFICEe FREDERIC COOK AND BUROHARD THOENS, OF NEW ORLEANS, LOUISIANA.
FEED-WATERV REGULATOR.
SPECIFICATION forming part of Letters Patent No. 393,621, dated November 27, 1888.
Application filed February 19, 1887. Renewed May 8. 1888. Serial No. 273,262. (No model.)
To all whom it may concern,.- l
.Be it known that we, FREDERIC Coon, a citizen of the United States. and BUROHARD THOENS, a subject of the Emperor of Germany, residing at New Orleans, in the parishV of Orleans and State of Louisiana, have invented new and useful Improvements in Feed- Vater Regulators for Steam-Boilers,of which the following is a specification.
The object of our invention is to provide novel means for automatically regulating or graduating the supply of steamA to the feedpump or injector of a steam-boiler, whereby the requisite quantity of water is maintained in the boiler.
The invention consists in the combination of deviccs and their Inode of operation, herein after described and claimed, reference being made to the accompanying drawing, in which the tgure is a vertical sectional view of a feedwater regulator embodying our invention.
In order to enable those skilled in the art to make and use our invention, we will now describe the same in detail,referring to the draw- Ing, wherein- The Anumeral 1 indicates a cylindrical or other suitably-shaped casing having an upper pipe-connection, 2, with the steam-space of a steam-boiler, and a lower pipe-connection. 3, with the waterspace ofthe boiler. The lower end of the casing is-provided with a detachable cover, 4, and the upper end of the casing is provided with a screw-plug, 5, to which is coupled the blow-ott1 cock 6, andthe pipe 7 leading to the feed-pump or injector of the boiler, which pumpor injector it is not necessary to illustrate.
To the screw-plug 5 is secured the upper end of a vertical pipe, '8, having near its upper portion a series of longitudinal slots, 9, and at its lower end a screw-plug, 10, carrying a vertical tube, 11, contracted at its upper end above the slots 9, and depending below the plug 1() to enter a well, 12, formed by a tube, 13, depending from the bottom wall of a hollow tloatcylinder,14,provided with aguide,15, in the form of a tube having internal ledges, 16,whicl1 bear against and slide upon the pipe 8, said tube being connected by arms 17 or otherwise with the hollow Boat-cylinder. The top portion of the casing 1 is interiorly provided with a circular or other shaped guarddange, 18, surrounding the upper end 0f the float and extending below the steam connecting pipe 2. l
To the pendent tube 13 or other part ofthe float is secured a weight-receptacle, 19, or its equivalent, for properly submerging the oat in t-he water contained in the easing. The casing is provided with a water-gage, 20, to indicate the level of the water in said casing, and as thelevel of the water in the latter is supposed to be the same as that in the boiler the water-level therein can also be observed. The vertical sliding movement of the guide-tube 15 more or less closes the slots 9 of the pipe 8. The steam entering the pipeconnection 2 passes around and under the guard-fiange 18,
through the open portions of the slots 9 to the steam-pipe 7, leading to the feed-pump or injector of the boiler. This causes a suction or siphonage of the condensed water from the well12 and float 14, and keeps them free of the same. By closing the valve 21 in steampipe 7 and opening the blow-off cock 6 the condensed water in the tloat can be blown out before starting the steam-pump and regulator, after which the collection of condensed water is so tritling that it will pass with the steam into the cylinder of the steam-pump without harm. The buoyancy of the float will,by controlling the slots 9,- reguiate the flow of steam to the steam-pump or injector, and hence the speed of the latter will be regulated according to the requirements of the boiler.
The only working parts in this regulator where friction exists is where the guide-tube 15 works on the pipe 8; but as it is always either in steam or condensed water no deposit from the water in the boiler can be deposited ou the working-surfaces.
In case the boiler should prime and water pass over through the pipe-connection 2 into the regulator,itstrikes the guard-flange 18 and falls into the regulator outside the hollow dont, consequently no water from the boiler can ever enter the tloat except condensed steam.
The more or less weight in the receptacle 19 changes the relation of the water-level to the area of the steam-openings 9 in vertical pipe 8, so that the float can be set to admit the necessary steam to pumps to maintain a uniform water-level, even if the pump is disproportioned to size of boiler.
IOO
Having thus described our invention, what we claim isl. The combination, in a feed-water regulator, ofa laterally-pcrforated pipe with a verticallynnovalile float open at its upper end and receiving within it steam from the boiler, and the rising and falling movements of' which govern the How of steam to the pump or in` jeetor through a part of the iioat, gradually opening and closing the perforations in the said pipe, substantially as described.
.Z. 'lhe combinatioinwith a feed-water regulator, ol' a sliding fioat open at its upper end, and having an attached interior tube working over steam-openings to control the speed ol'` the pump, substantially as described.
3. The coinbination,\\ith a feed-water regulator,of the hollow float open at its upper end, the steam pipe having steam-openings and on which a guide of the oat works, and the stcani-siphonage for the float, substantially as l described. 4. The combination,with a feed-water regnl I i l l i i lator, of a hollow float open at its upper end, and a steam Siphon-tube worked by the flow I of steam around its point to free the oat of condensed water, substantially as described.
5. The combination, with a feed-water regnlator and a float having an upper open end,of a pendent guard-Harige to prevent the ow of steam striking the ioat, and to cause the condensed water to fall outside the float,substan tially as described.
6. The combination, with the casing, ofthe pendent tube having longitudinal slots, ahollow float having an attached lguard acting to more or less open and close the slots by the rising and falling movements of the lloat, substantially as described.
7. The combination, with the casing, ol" the pendent tube havingslots, a hollow loat having a well at its lower end, a guide secured to the iloat and working over the slots to more or less close the same, and a steam Siphon-tube arranged in said slotted tube and entering the well of the ioal', substantially as described.
In testimony whereof weal'lix our signatures in presence ot' two witnesses.
