UNITED STATES HENRY A. HURCKES, 0F CHICAGO, ILLINOIS.

To all whom t may concern: Y

, Beit llniown thatl, HENRY-A. HURoKEs,

a citizen of the UnitedStates, 4residing at vChicago, inl thecounty of Cook and State A.of Illinois, have invented certain new and useful Improvements in Feed-Tater Regulators, of which the following is .a specilication.- l

This invention relates to feed water regulators especially adapted for use in connection with steam boilers.. v y

Briefly stated an important object of this invention isto provide a feed water regulator wherein the Lipper and lower valve' of the same are of the same area and are per fectly balanced to reduce rattling and binding to a minimum and to bring about firm seating ofthe valve. y

-A further and equally importantobject of the invention is toprovide a valve ofthe character specified which may be easily assembled and installed and which may be economically manufactured. Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing-,forming a part of this application and in which like numerals are employed to designate like parts throughout,

Figure 1 is a vertical sectional view illustrating the application of the improved valve; f

Fig. 2 is agroup perspective of the upper and lower valves;

Fig. 6 is a horizontal sectional view taken on line 6-6 of Fig. 3; y

Fig. 7 is a perspective of a locking sleeve or groove embodied in thev invention.

In the drawing wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 5 designates what might be said to be a float chamber within which a float 6 is arranged. A float arm 7 is fulcrumed at 8 within the chamber 5 and has connection as indicated at 9 with the upper vportion of a valve stem 10.

ln carrying out the invention the stem 10 is arranged in a casing 11 having inlet and Application yfiled A-prl 16,k 1924. Serial No. 706,977.

outlet ports

12 and 14 respectively.. A valve casing` having upper and

lowerrings

16 and 17 respectively is located in the casing and the lower ring 17 is externally threaded for engagement with the lower wall of the inlet port. As clearly illustrated inFig.vr 1 the upper ring 1G is externally smooth andv is snugly received in an opening in the upper side wall of the port 12. Orfy course the inner end of the port 12is-closed and the water may enter the casing only by passin O lthrough the upper and lower rings loand 17 respectively. y

l/Vith reference to Fig. 3Y it will be ob.- served that the upper and

lowerpvalves

20 and 21 are arranged to engage the cham. Y

f ered seats `of the

rings

16 and 17 respectively and tlie'valves are mounted uponfthe stem 10, theupper valve being rigidly and ,more or less permanently. mountedion the stenrwhifle the lower valve 21 is confined between an annular shoulder 24 formed on the stem and the enlarged or flared upper end of a fasteningtube 2li The tube 26 has its lower end internally threadedfor threaded-yengagement with the lower end of the stem, and the lower portion of the tube or fastening sleeve 26 is exten.

nally enlarged and'is slidable in a bearing 28. A plurality of arms 27 `extend downwardly and inwardly from the ring 17 and join the bearing 281tosupport the same in alinement with the a'Xs of the valve.

Fig. 6 illustrates that the arms 27 are `oppositely arranged and they do not in Vany way interfere with the free flowof water when the movements of the float 6 operate the valve. 1n carrying out the invention upper and lower rings'l and 17 are joined by spaced longitudinally extending connectf ing members or ties 32, the lower portions of the ties 32 being positioned to guide lthe valve 21 and the upper portions of the members 32 being off-set to provide for the free passage of water.v y y The upper valve 2O is guided in its ver tical movement by a plurality of longitudinally extending guide strips or members 34E having their upper ends connected to or formed integral with an annulus 36.

To. assemble the improved valve it is merely necessary to place thelower valve 21 on edge and pass the same between two of the connecting ties 32 after which the lower valve 21 is positioned on its seat. The stem casing and through the lower valve 21 and the fastening sleeve 26 is subsequently applied to securely fasten the lower valve 21 in position.

lVhen the sleeve 26 is threaded tightly in engagement with the under side ot the lower valve 21 the valve is ready for operation and as both valves are of the same diameter the structure is well balanced and no parts of the same will rattle or bind when the valve is operated. It is important to note that t-he diameter of the upper portion o'l the stem is the same as the external diameteiI of the tube 26 so that the valve is balanced in this respect also.

Having thus described the invention, what is claimed is:

l. A eed and water regulator comprising upper and lower valvev rings having seats, spaced parallel connecting` ties joining said rings, upper and `lower valves of the same diameter adapted for contacting with said seats, a stem permanently connected to the upper valve and passing through the lower valve, said stem being provided with an annular shoulder contacting with the lower valve, and a sleeve of the same diameter as said `stem above said annular shoulder threaded on to the lower portion of the stein and contacting with the under side of the lower valve to hold the lower valve in position.

2. A feed and water regulator comprising upper and lower valve rings having seats,

spaced parallel connecting ties joining said rings, upper and lower valves of the same diameter adapted for contacting with said seats, a stem permanently connected to the upper valve and passing through the lower valve, said stem being pro-vided with an annular shoulder contacting with the lower valve, a sleeve threaded on to the lower portion of the stem and contacting with the under side of the lower valve to hold the lower valve in position and a plurality of arms extending downwardly 'from the lower valve ring and having a bearing receiving the lower portions ot said sleeve for guiding the same. i

3. A ieed and water regulator comprising upper andvlower valve rings having seats, spaced parallel connecting ties joining said rings, upper and lower valves oi the same diameter adapted for contacting with said seats, a stem permanently connected to the upper valve and passing through the lower valve, said stern being provided with an annular shoulder contacting with the lower` valve, a sleeve threaded on to the lower portion of the stem and contacting with the under side of the lower valve to hold the lower valve in position and a plurality of arms extending downwardly from the lower valve ring and having a bearing receiving the lower portions of said sleeve for guiding the same and a plurality of upwardly extending guide members formed on the upper ring and having an annulus connecting the same.

4. A feed and water regulator' comprising upper and lower valve rings having seats, spaced parallel connecting ties joining said rings, upper and lower valves of the same diameter adapted for contacting with said seats, a stem permanently connected to the upper valve and passing through the lowerl valve, said stem being provided with an an nular shoulder contacting with the lowel` valve, and a sleeve of the saine diameter as the stem above said annular shoulder threaded on to the lower portion of the stern and contacting with the under side oi the lower valve to hold the lower valve in po sition, said lower valve being insertable between said spaced ties whereby the stem may subsequently be inserted through the same.

5. A feed and water regulator comprising upper and lower valve rings having seats, spaced parallel connecting ties joining said rings, upper and lower valves of the same diameter adapted for contacting with said seats, a stem permanently connected to the upper valve and passing through the lower valve, said stem being provided with an annular shoulder contacting with the lower valve, and a sleeve threaded on to the lower portion of the stem and contacting with the under side of the lower valve to hold the lower valve in position, said lower valve being insertable between said spaced ties whereby the stemmay subsequently be inserted through the same, the connecting ties -for the upper and lower valve rings having their lower portions oli'set to serve as guides for the lower valve.
