Specification of Letters Patent.

Patented duly d, 1911.,

Application tiled @ctober 27, 1909. Serial No. 524,798.

To all whom it may concern.'

Be it known that ll, WILLIAM l-l. BRUM- Mnn, a citizenof the United States,and resident of Venice, Madison county, lllinois, have invented certain new and useful '1mprovements in Boiler-Feed- Pump Regulators, of which the following is a specilication containing a full, clear, and exact description, reference being had tothe ac-4 ized to prevent the steam from striking the diaphragm and to keep the diaphragm in a pliable, operative condition.

For the above purposes my invention consists in certain novel features of construction and arrangement oit parts as will be hereinafter more fully described, pointed out in the claim and illustrated by the accompanying drawing, in which: y

lfigure l is a vertical, sectional elevation through the complete regulator; and, Fig. 2 is a sectional plan taken on the line 2 2 of lF ig. 1.

Referring by numerals to the accompanying drawing: 1 designates the housing of the valve proper, 2 `the valve seatsA therein and 3 thev valves ,of the ordinary balance-valve t pe. y

ya designates a steam pipe leading from the boiler and communicating with the housing 1, and 5 designates a steam pipe leading trom the housing 1 to a feed-pump (not shown).

t head 6 is secured to the valve housing on its upper side, and formed integral therewith are standards 7 projecting upwardly from the upper face of the head 6, and formed integral with the upper extremities of the standards is an annular ring 8. ported by the standards, on top of the an- 5 nular ring, is a head 9 there being an insu- Suplating ring and head 9. Secured to the head 9 is a diaphragm casmg consisting of a lower diaphragm-casing member 11 having an integral hollow extension 12 which rests upon the head 9 and an upper diaphragm-casing member 13, the members 11 and 13 being elliptical in cross section and having integral flanges 14 which are united by the bolts 15. llnterposed between the members 11 and 13 is a leible, iibrous diaphragm 16. Y

Formed in the upper-'diaphragm-casing member 13 is an internally threaded opening in which is seated a Water-supply pipe 17. 'lthe heads 6 and 9 are each provided with stuiling boxes 18, and arranged for operation through ,said stuffing boxes is a sectional valve stem comprising a section 19 provided with an enlarged head 20 for operation in the diaphragm-casing and through the stuffing box carried by the head 9; a section 21 detachably secured to the section 19 and arranged for operation through the head 6 and stuing box carried thereby, and, a section 22 which is pivotally secured to the section 21 and carries the valves 3.

lmpinging between the head 20 of the section 19 of the valve stem and the'head 9, is an extensile coil spring 23 arranged in such manner as to normally hold the valves 3 open.

Secured to the housing 1 and incommunication with the interior thereof is a steam pipe 24 having a coil 25 at its upper end. Connected and in communication with the holloviT extension 12 of the diaphragm-casing and located in the pipe 24', is a valve 26.

Secured tothe housing 1, on the lower extension thereof, is a head 27 having an integral stuling box 28 through which is 'extended a rod 29 which rodisxthreaded to the head 27 and carried by said rod isja handle 30. The upper end of the rod 29 is arranged tor'engagement, at times, with the lower end of the valve stem 22.' By this arrangement ot parts, l am enabled to operate the valves manually in case the automatic means is temporarily disabled.

lt will be observed that the head 20 at the upper end of the said valve-stem rests loosely against the underside of the said diaphragm 16, and that the spring 19 nor- 10 interposed between the ring 8- mally urges said head into contact with the imperforate center of said diaphragm.

In practical operation, assuming the pipe "L to be connected to receive steam from a i boiler, the 4pipe 5 to be connected with -a feed-pump andthe 'pipe 17 being connected with a water-supply pipe from the feed- Eump to the boiler, the pipe 17 being a ranch from said water pipe, steam from the boiler (not shown) is admitted to the housv ing l, and, assuming thatthe valves are in t is .to be understood in this connection,

that the pipes 4, 5 and the pipe (not shown) from the pump leading to the boiler together with the pipe 17, are normally open and in condition to feed steam to the pump and to permit the passage of Water from the pump to the boiler. It is to be understood, further, that the valve 26 in the steam pipe leading from the housing l to the diaphragm-casing is normally open. v

It will be obvious that steam admitted to the housingl will pass upwardly through the pipe 24 and into the diaphragm-casing and Iwill exert a pressure upon the dia-v phragm equlvalent to the boiler pressure,-

and, when there is an excess water and steam pressure within the boiler and within the water-supply pipe to the boiler from the pump (not shown), such pressure is exerted through the pipe 17 upon thel upper face of the diaphragm and such pressure will overcome the combined pressures of the spring 23 and the steam pressure within the diaphragm-casing beneath the diaphragm. Thus the diaphragm will move the valve stem downwardly and seat the valves 3 and cut oi communication of steam from the boiler to the pump and thus stop the water feed to the boiler.

An example of the operation of my improved regulator follows: Assuming all of the pipes to be open and the pump operating with one' hundred pounds pressure of steam within the boiler, it is obvious that there will be one hundred pounds steam pressure on the lower face of the diaphragm and that the pressure upwardly on the diaphragm by the spring is twenty pounds, and

-normal boiler pressure and the excess pressure 'of waterand steam ,within the boiler.

It is obvious 'by reason of the connection between the sections 19 and 21 of the valve stem, that the tension of the spring may be regulated as required to adjust the device for di'erent pressures of water and steam within the boiler. v

The provision of my improved waterv holding diaphragm-casing makes possible the use of a flexible, fibrous diaphragm such as leather which I have found in practice to be more efficient than the metallic diaphragms.

The improved boiler feedpump regulator, comprising a valve housing, a balanced valve in said housing, a diaphragm casing located directly above said housing, a' diaphragm in said casing, a valve stem connected to said valve and extending upward to said casing andhaving its upper end in contact with said diaphragm, a spring for holding said stem in contact with said diaphragm, a steam pipe 24 extending upwardly from the said housing, and having a condensing coil 25 located in a plane above the bottom of the said casing, so that a body of water will be maintained within said casing above the steam pipe entrance thereto, a valve 26 in said steam pipe below said coil, and a water pipe connected to said casing above said diaphragm. a

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses'.

WILLIAM H. BRUMMER.
