App-liea tidn filedmaj 15, 1917'. Serial K651685766.
T0 all ed/tom it camera -Be=it known that I, ETHAn some, a citizen cf the United States, residing at Linton,
in the county of Emmo'ns and State of N orth'Dak'ota,have invented new and useful 1 Improvements in Automatic Boiler Feed Mechanisms, of which thefollowing is a specification. A
This invention'ielates to automatic feed devices for boilers and more'particularly to afloat controlled mechanism which operates when the water 18 above or below apre'deter mined lev'elto actuate aninjector.
One of the objects of the invention is to provide an automatic boiler feed comprising a paii-of steam lines leading upwardly throng-lithe water in a boiler and terminatmg above the water level, the flow of steam through said lines b'eing governed by individual valves operated by'floatmechanism, the valve beingopened at different times to feed 'the stea nto anengine for opening or closing an injector "valve.
The invention also aims to generally'im prove automatic feed mechanism for boilers to render it morepracticahuseful, efficient andcommercially desirable.
WVith these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts aswill be hereinafter fully described, illustrated and claimed;

Fig 6- is a perspective view of the float operated levers andfloatyand N Fig. 7 is. a 'longitudinal"sectional view similar ito Fig" 3 showing the other valve from that shown in Fig. 3.
Referringin detail to the drawings by numerals, 1 deslgnates a steam boller which" r is supplied with water through the steam injector pipe 2 which latter is supplied with steam by the pipe ha vingjan injector valve 4 equipped with a handle 5. -My invention aims toprovide asimple and practical automatic mechanism for opening and closing, the injector v'alve tomaintain the water level practically constant within the boiler.
In the preferred embodiment of my dc" vice, I- provide a pair of steam linesgen erally designated 6 and 7 which lead upwardly through the water within the boiler to 'a termination thereabove. Forming a part of each of'the steam'lines'is a valve casing-'8. These casings are cylindrical; are closed at their upper ends and areconnected vertically within the boiler to the end thereof by the arms or braces The casings are each formed on their lower ends with right angle extensions 10 which are engaged with the exit openings 11 through the boiler as shown. This manner of connecting the errtensions provides a further-support for the verticalvalve casings. Cylindrical sleeve valves 12 and 13 operate respectively withinor openings 15 opposite the racks so that the latter may be engaged by the segmental toothed heads of the fioat operated levers 16. These levers are pivoted on trunnions 17 carried by arms 18 fixed to a connecting bracket 19 between the valve casings as illus- 'trated. The long arms of the lovers are secured to a'fioat 20 and the short arms are formed on their terminals with the segmental heads 21 provided with the gear teeth 22 which mesh withthe teeth 1 1-, of the racks.
A movement of the float in response to a change of water level causes the levers 16 to move the valves longitudinally. The valve 12 is formed with a port 23 near itsupper end which is adapted for registration with a port 2% in the corresponding valve casing andthe valve 13 is provided with a port 25 adapted for registration with the port 26 in the other valve casing. These ports are each connected to steam pipes 27 form-- ing ElfPfll'tOfThG steam lines 6 and When the water level in the boller is at the desired or normal height the float controlled levers 16 hold the valves in a neutral water level will elevate the valves and register the port 25 with the port 26, and that a rise of water level above normalwill lower the valves to close the port 26 and open the port 24:.
Steam flowing through the valves is conducted to an engine 28 by means of the pipes 29 and 30. The engine comprises a cylinder 31 having the intake ports 32, 33 and the discharge ports 34, 35, the intake ports being preferably in the side of the cylinder and the discharge ports being in the end thereof. Within the cylinder is a piston 36 having the piston or valve rods 37 and 38 which extend through the exhaust ports and which carry respectively, the valves 39 and 40. The rod 37 connects with the turning lever 41 on the injector valve rod 5. Clamps 42connect the cylinder to the steam line 3.
When the float 20 drops to open the port 26, steam will flow through'the steam line 7 into the cylinder 31 through the port 33 and .force the piston 36 to the left to open the injector valve, whereupon the water will be injected into the boiler. \Vhen the piston has been moved sufliciently far to open the injector valve, the valve 39 will have closed the exhaust port 35 to prevent further escape of steam from the boiler. When the water level reachcs normal or exceeds the same, the floatQOwill raise to close the port 26 and open the port 2-1. Steam flowing through the port 2st will be conducted to the port 32 of the cylinder 31 and move the piston therein to the right to close the injector valve as will be clearly understood.
From the foregoing description taken in connection with the accompanying drawings,
it will be apparent that I have devised a very practical and efficient automatic boiler feed mechanism which is controlled by the water level within the boiler and which will maintain this level at a practical constant having ports connected therewith, valves slidable within said casings to close said ports to prevent av flow of steam through Copies of this patent may be obtained for drical valve casing in each of said"steam' lines, a sleeve valve slidable within each of said casings and having a port adapted to be registered with the port of the casing, rack teeth formed on each of the sleeve vaives, the valve casings being slotted opposite said rack teeth, and float controlled levers pivoted intermediate their ends, each of said levers being provided with a toothed segmental head on one terminal for engagement with one of the racks.
3. In an automatic teed control for boilers, a pair of vertical valve casings mounted within the boiler, each casing being formed.
with an intake-port, asteam pipe connecting with each intake port, the casings being closed at thcirupper ends and opened at their lower ends, steam pipes connected to the lower ends of the casing and leading to the exterior of the boiler,- means supplied with steam from said pipes for actuating an injectorvalve, a'sleeve valve. slidabie within each of said valve casings, float controlled means for actuating said valves, the valves being so arranged that a drop in water level will admit steam to one of the valve casings and that a rise in water level will admit steam to the other of the valve casings.
4.111 an automatic teed control for boilers, a pair of vertical valve casings mounted. within. the boiler, said casings being closed at their upper ends, pipes connected to the lower ends of the casings and leading to the exterior of the boiler, sleeve valves slidable within said casings and formed with ports adapted to register with'ports of the casings, float controlled means for actuating the valves to admit steam into one of the casings when the water level drops below normal and to admit steam into the other of the casings when the water level rises above normaland means actuated by steam flowing through saiducasings for controlling an injector valve, 1
In testimony whereof I affix my signature.
