FILLING-VALVE Specification of Letters Patent.

Patented March 2, 1909.

Application filed November 5, 1907. Serial No. 400,811.

To all whom it may concern:

Be it known that I, EDWARD E. GOLD, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Filling- Valves, of which the following is a specification.

This invention relates to means for illling tanks or pipes of indirect heating systems with water and for other similar purposes. For this purpose there is provided a nipple or mouth-piece with a lower opening for the admission of water and an upper opening for the escape of air, and means are provided for simultaneously shutting oil both the water and the air openings. Preferably the shutting oil means are connected also with a funnel which when turned up to receive water efiects the opening of both passages, and when turned down closes both passages.

The accompanying drawings illustrate an embodiment of the invention.

Figure 1 is a side elevation of the apparatus applied to the tank of a Baker heater. Figs. 2 and 3 are longitudinal sections of the apparatus in diflerent positions. Figs. 4: an 5 are sectional views on the lines 44 and 55 respectively. Fig. 6 is an elevation of the outer end of the nipple or mouthpiece.

Referring to the embodiment of the invention illustrated, a closed tank is indicated at A, which in the Baker system is arranged at the top of the water circulation system. Into one side of this tank is screwed a nipple B which is provided with a large water passage C and a smaller air passage D, the two passages extending parallel with each other throughout the length of the nipple. On the end of the nipple, preferably integral therewith, is a disk E through which the passages C and D are continued, and which is circular and has its center above the air passage, as, for example, on the line F, Figs. 2 and 3. The disk E is provided, at the side opposite the passages, with a depression or groove G for lightening it, and for an additional purpose hereinafter referred to.

Facin the disk E is a valve disk H of slightly ess outside diameter and which is provided with passages J and K adapted to register with the water and air passages of the nipple. The center of the disk II is also on the line F, just above the passages described, so that when the valve disk II is in the position of Fig. 2 the passage J registers with the passage G and the smaller passages Ii and I) also register with each other; but when the disk II is inverted to the position of Fig. 3 both the passages C and D are closed. In the list passage water may be freely admitted to the tank to bring it up to the level of the air passage D, after which it will be prevented from rising any higher in the tank, but will flow out of the passage D. In this way a space will be left at the top of the tank as is desired for a cushion of steam or air. When the disk is turned to the position of Fig. 3, further outflow of water or steam will be prevented. The valve disk II ray be held up to the nipple or the disk ID by means of a ring 11 having a slightly larger internal diameter than the disk H, and screwing upon the disk E so that its inward flange M holds the two disks together.

A section of pipe N, preferably curved and connected to the disk liI, preferably by being cast integrally therewitl'i, is provided with a continuation of the passage J. The air passage K through the valve disk preferably leads directly to the free space. The pipe N is bent in the direction toward the center of the disks, that is to say, upward when the assages are open, and may be provided at its outer end with a funnel O for convenience in pouring in the water. In order to turn the valve disk H to the closing position it is only necessary to invert the funnel, the valve disk swinging about the center line F, and its solid ortion coming directly over the open ings (l and D of the nipple when the funnel is turned down as in Fig. 3. The groove G is circular and of substantially half a circle in length, and its opposite ends serve as stops to limit the rotation of the valve disk H the latter carrying a pin or screw P which projects into said groove. The pin is so located that in the open position of the valve it strikes against the right-hand end of the groove (Figs. 2 and 6) and in the opposite or closed position of the valve it strikes against the left-hand end of the groove. It serves thus to insure to a nicety the correct register of the passages D and K, and also to determine the exactly opposite osition.

The ring L is preferab ly provided with finger holds Q for turning it, so that when it is desired to use the valve the ring may easily be unscrewed slightly so as to permit the funnel to be turned up readily and clamped in the turned-up position by turning the ring back. Similarly, after filling the tank the ring needs only to be loosened slightly to permit the turning down of the funnel, after which the ring is reclamped and the tank is tightly closed. The entire apparatus is very compactly made and easily assembled.

What I claim is:--

1. The combination with a fixed closed vessel of a lzot water heating system, of a nipple at the side of the same for filling it and having a pair of horizontal passages C and D therethrough for admitting water and permitting the escape of air respectively, a valve disk H eccentric to said nipple and having at one side of its center passages J and K adapted to register with the passages C and D respectively, said valve disk adapted to rotate to bring the respective passages into and out of register.

2. The combination with a fixed closed vessel of a hot water heating system, of a nipple at the side of the same for filling it and having a pair of horizontal passages C and D therethrough for admitting water and per mitting the escape of air respectively, a valve disk H eocentrc to said nipple, and having at one side of its center passages J and K adapted to register with the passages C and D respectively, said valve disk adapted to rotate to bring the respective assages into and out of register, and a pipe l carried by said valve disk and through wh ich thepassage J is continued bending in a direction toward the center of the valve disk, whereby when said disk is turned to bring the respective passages in register the outer part of the passage J is turned upward to facilitate in- 3. The combination with a fixed closed vessel of a hot water heating system, of a nipple at the side of the same for filling it and l aving a pair of horizontal passages C and D therethrough for admitting water and permitting the escape of air respectively, a valve disk l-l eccentric to said nipple and having at one side of its center passages J and K adapted to register with the passages C and D respectively, said valve disk adapted to rotate to bring the respective passages into and out of register, a disk carried on the end of the nipple and concentric with the valve disk H, a ring L for holding the two disks together, said disk E being provided with a groove G, a pin P carried by the valve disk H and traveling in said groove so as to limit the movement of the valve disk H relatively to the disk E, a pipe N carried by said valve disk and having a passage com municating with the passage J thereof and extending toward the center of the valve disk, whereby when said disk is turned to bring the respective passages in register the outer )art of the passage J is turned upward to facilitate introducing a liquid, and a funnel carried at the outer end of the pipe N, the parts being arranged to bring the funnel O in the uppermost position at one of the limits of the rotary movement of the valve disk, and in the inverted position at the other limit.

In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.

EDWARD E. GOLD.
