FEED-WATER VALVE FOR BOILERS.

Specification of Letters Patent.

Patented July 13, 1915.

Application filed September 3, 1913, Serial No. 787,833. Renewed May 3, 1915. Serial No. 25,630.

To all whom it may concern:

Be it known that I, HENRY PONGRAT, a citizen of the United States of America, and resident of Canal Dover, county of Ti1scarawas, and State of Ohio, have invented certain new and useful Improvements in Feed- Water Valves for Boilers, of which the following is a specification.

This invention relates broadly to a water feed valve for boilers and specifically to a double feed apparatus for boilers.

The primary object of the invention is to provide a simple and convenient valve through which water may be delivered to a boiler, dispensing with the usual two lines of feed pipe with the series of valves employed therein.

A further object is to provide a double feed apparatus through which water may be delivered to the boiler in either of two ways, each having therein a single check valve, one of said ways being wholly closed when the other is in operation, thus affording ready access for the removal of the check valve and for grinding the valve-seat in one of said ways without interfering with the feed through the other of said ways.

A still further object is to provide a valve of the character mentioned which may be operated to wholly cut off the passage of water therethrough, and having means whereby it may be locked against movement from the cut-off position for afiording an element of safety in cases where it is necessary for an attendant to enter the boiler.

With these and other objects in view, the invention resides in the features of construction, arrangement of parts and combinations of elements which will hereinafter be exemplified, reference being had to the accompanying drawings, forming a part of this specification, in which Figure 1 is a front elevation of the invention; Fig. 2 is a side elevation ofthe same; Fig. 3 is a top plan view; Fig. 1 is a substantially central vertical section; Fig. 5 is a transverse horizontal section'on the line 55, Fig. 1; Fig. 6 is a similar section on the line 66, Fig. 4,; and Fig. 7 is a detail view, reduced, illustrating the locking means.

Referring to said drawings, in which like designating characters distinguish like parts throughout the several views- 1 indicates a central body portion havlng two similar upright arms 2 and 3 disposed on opposite sides thereof and integral therewith. Said body is supported by a pair of f oppositely disposed integral outwardly' curved legs 4: and 5 which project upward from an integral flanged base 6 which is adapted for mounting on a boiler at a suitable point.

Extending vertically through the body 1 is a large central bore having a slight downward taper and within which is seated a correspondingly-tapered cone 7 which constitutes a rotatable valve, a ground joint being formed between said body and said cone. A threaded stem 8 is formed on the lower end of said cone, and threaded thereon against a metal washer 9, having integral therewith a plurality of upwardly and outwardly curved flexible fingers 9, is an adjusting nut 10, said fingers being seated in recesses 11 provided therefor in the under face of a washer 12 which is fitted upon a non-circular portion 7 at the lower end of said cone 7. From this it will be apparent that the cone 7 is held in a downwardly drawn seated position under a yielding'tension, and that said cone may be adjusted by tightening of the nut 10 from time to time to compensate for wear. It will further be seen that, owing to the washer 12 being non-rotatable on the portion 7 of the cone, the said washer 12, washer 9 and nut 10 follow the cone when the latter is rotated in either direction, chance rotation of the nut with respect to the stem being thus guarded against.

Provided in the cone 7 are two ai-cuately curved cored-out passages 13 and 14, the opposite ends of each of which open through the face of the cone at a spaced distance apart and in substantially the same vertical line. Formed on the front side of the body 1 is an outstanding tubular arm 15 adapted for connection to a water supply pipe, as 16, the passage 17 through said arm communicating with a passage 18 provided in the wall of said body, the last mentioned passage having two separate outlets 18 and 18 which open at spaced distances apart into the large central bore in which the cone 7 is mounted.

In one position of the cone 7, as is shown most clearly in Figs. 4t and 5, the outlet 18 is closed against the passage of water, while.

the outlet 18 registers with the upper part of the passage 13 in the cone. In said position the lower part of said passage 13 registers with a curved passage 19 leading outward through the body 1 and upward into the arm 3 where it communicates with a valve chamber 20 provided in said arm. Threaded vertically into a socket provided therefor in the bottom of the chamber 20 is a tubular member 21 having a valve seat 22 formed at its upper end, and vertically movable within said member are the guide-legs 23 of a check valve24= which normally seats by gravity, or by return water pressure, upon the seat 22. Said tubular member 21 and valve 2 1 are introduced in their work ing positions through a vertical opening in the upper end of the arm 3 which is thereafter closed by a threaded cap 25.

Leading inward from the valve chamber 20 through the body 1 is a passage 26 which, when the cone occupies the position shown in Figs. 4, 5 and 6, registers with the upper part of the passage 1 1 in said cone. The lower part of said passage 14: at the same time registers with the end of a passage 27 .which leads downward through the leg 5 and communicates through a port 28 in the base 6 with the interior of the boiler upon which said base is mounted.

From the foregoing it will be seen that, when the cone occupies the position shown in Figs. 1, 5 and 6, water entering through the supply pipe 16 traverses a circuitous course, passing through passage 17 in arm 15, thence through outlet 18 of passage 18 to and through passage 13 in the cone 7 thence through passage 19 in the body 1 and the arm 3 to and through the interior of member 21, and, forcing the check valve 2st off its seat, passes into the valve chamber 20, whence it passes through passage 26 to and through passage 141 in the cone 7, thence through. passage 27 in leg 5, and to the boiler through port 28.

Vfhen the check-valve 2 1 or its seat require attention, as when wear occurs, the cone 7 is turned or rotated in the direction indicated by the arrow in Fig. 3 to the position indicated in dotted lines in said figure, the lever 29 pivotally mounted between a pair of upright lugs 30 on the cone being employed for effecting the rotation. This action cuts off the water supply through the passages in the arm 3, leg 5 and right side of the body 1 and brings the passages 13 and 14 in the cone into register with passages in the arm 2, leg 1 and left side of said body, the last mentioned passages being substantially identical with those on the opposite side. The flow of water from the supply pipe then passes through passage 17 in arm 15, thence through outlet 18 of passage 18 to and through passage 1 1 in cone 7, thence through passage 19' in the body 1 and the arm 2 'to and through the interior of member 21, and, forcing the check valve 2 1 off its seat, passes into the valve chamber 20, whence it passes through passage 26 to and through passage 13 in the cone 7, thence through passage 27 in leg 1-, and to the boiler through port 28.

As is obvious, when the cone 7 occupies the last above described position, access may readily be had to the valve chamber 20 for removing the check valve 2a or for grinding valve-seat 22, removal of the cap 25 only being necessary. Likewise, when the cone occupies the first above. described position, access may be had to valve 2-1 and valveseat 22 by removal of cap 25.

For enabling the proper positions of the cone 7 to be accurately gagedthat is, for marking the limit of movement required to cause the passages 13 and 1st to accurately register with the passages in the body 1 stop-shoulders or lips 31 and 32 are provided on the top of the body 1 adapted to be respectively engaged by the heads 33 and 3% of small screws directed into the side of the cone 7 when the proper limits of rotary movement have been reached.

When it is desired tocut off the passage of water to the boiler, the valve cone 7 is rotated to any intermediate position wherein the openings of passages 13 and 1st fail to register with the water passages in the body 1. To look said cone in cut-off position, the same is turned to a position wherein the lever 29 stands at substantially a right angle to a line connecting the arms 2 and 3, after which a pin 35 which normally overlies said lever, as shown in Figs. 1, 2 and 3, is withdrawn from a pair of upright lugs 36 between which the body of said lever normally lies, and said lever body is elevated to the position shown in dotted lines in Fig. 7, whereupon the pin 35 is replaced so as to occupy underlying relation to said lever body. In this position a downturned nose 37 formed on the front end of said lever seats in a socket 338 provided therefor in a projection 39 formed on the front face of the body 1; and, as is apparent, rotation of the valve cone '7 with respect to said body is thus effectually prevented. To prevent unauthorized lowering of said lever from its elevated cone-locking position, a small padlock, as 40, shown in Fig. 7, may have its hasp projected through an opening or slottl provided in the pointed end of the pin 35.

From the foregoing it will be understood that the check-valves 24c and tubular mem: bers 21, the latter having the check-valve seats formed thereon, constitute practically all the parts which are 'subjectedto undue wear under the action of the water; and further that access may be readily had to said parts for repair or renewal without cutting ofi' the feed of water to the boiler.

The passages through which the water courses in passing through the device have no abrupt turns or bends therein which act to unduly retard the passage of the water, and no abrupt shoulders or ledges are presented which are liable to retard the Water or to become worn by the action of the latter.

Provided in an annular flange 42 carried by each tubular member 21 are oppositely disposed recesses 43 adapted to receive the prongs of an instrument whereby said member is threaded to and from its seat.

Each of the check-valves 24 and 24: presents an annular fiat shoulder 44: to the jet of water which is forcibly directed against the face of the valve from between the guiding portion of the latter and the walls of the tubular member 21. Thus, the inclined portion of the valve-face does not receive thereagainst the full force of the entering water, and said face is therefore not subjected to the wearing action of the water to the same extent as would be the case if said inclined portion were extended entirely to said guiding portion.

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