M. R. RICE VALVE Filed Dec. 17, 1941 INVENTOR. wfiib' REL/ce Patented Feb. 27, 1945 UNETED STATES PATENT GFEECE (Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) 1 Claim.

This invention in general relates to valves, and in particular to valves for the control of the passage of fluid, either gaseous or liquid, from one container to another.

To a certain extent this invention is an improvement on the apparatus disclosed in United States Patent No. 2,237,559, granted `to A. A. Jenne. The apparatus disclosed in the Jenne patent, while working fairly satisfactorily, has certain material deficiencies, in that it does not embody a leak proof valve, which in all instances is desirable, in many necessary. In the employment of the apparatus disclosed in my invention, poison gases or liquids may be passed from one container to the other to which the apparatus is connected, without danger off escape of the gas or fluid. My device may also be employed in passing air from a tire filled with air to a .partially deflated tire, such as is intended in the apparatus described in the Jenne patent.

It might also be mentioned that the portion of my device shown in Figure 1 of the drawing, may be employed to keep an inner tube deated while undergoing repair, without removalof the valve core, as is now customarily done.

The several objects and features of my invention will be more readily understood and appreciated upon reading the following description in connection with the accompanying drawing.

In the drawing:

Figure l and Figure 2 are views in cross section showing the respective valves in connection with the valve stems of the uid containers, the containers themselves not being shown.

Figure 3 is a cross section View of alvariation in the valve structure.

Referring now to the drawing in detail in which like numerals designate like parts, the numeral I designates a conventional valve which includes a casing i and a plunger 2 which may be depressed against the action of a spring 3 to open the valve. Similarly the uid container from which the fluid is to be transmitted is provided with a casing a plunger 5, and a spring 6. A conduit, not shown, connects the shank l of the valve illustrated in Figure 1 with the shank t of the valve illustrated in Figure 2.

The respective shanks I and 8 connect with the respective lock nozzles, shown in the drawing, which comprise slotted cylindrical casings 9 and IIJ disposed at right angles to which are the respective hollow shanks `'I and 8 previously described. A cylindrical opening is disposed in the respective bases of the cylindrical casings S and It, into which openings are nserted'the 55 in valve stems I and 4, as illustrated in Figures 2 and 1. In these respective valve openings are the compresible washers H and I2. Disposed within the respective cylindrical casings 9 and I0 are the movable nozzle heads I4 and I3. Operating vertically through the respective heads I5 and I6 of the nozzle heads I3 and I t are pins I'I and I8. Flanges I9 and 20 are disposed on the respective outer peripheries of the nozzle heads I3 and I 4. Conical rubber washers 2I and 22 are Kdisposed between the respective heads I5 and I6, of the nozzle heads I3 and I4, and the respective pin heads 23 and 2d, disposed on the upper ends of the respective pins I 'I and i3. Pivot pins 25 and 26, carried by the casings it and 9, support operating levers 2l and 28 having cam surfaces 29 and 30 integral therewith.

To connect the lock nozzle with the container valve, the operating lever 2l or 28 is first turned parallel to the pin I1 or I8, as the case may be, to the position shown in the drawing; the casing is then slipped over the valve stem container, as illustrated in Figures 1 and 2, and the operating levers 2l and 28 are then turned down at right angles to the pins II and I8.` When this is done, the cam 29 `or 30, as the case may be, forces down `the pin 23 or 24, thereby depressing the pin I'I or i8, and washer 2I or` 22, and causing the washer to seal tightly the upper chamber 32 or 33 of the respective casing 9 or IIJ, and likewise simultaneously compressing the respective washer II or I2 in the respective base of the container i6 or 9, and thereby sealing tightly the lower container chamber 36 or 3 1; at the same time the respective valve stemr 2 or 5 is depressed, thereby permitting passage of uid from the container to which the valve stero. 4 is connected to within the container to which the valve stem l is connected until the fluid in the two respective containers is equalized, unless the flow is stopped sooner by placing `the operating lever handle 28 in a position parallel to the pin I8. In using the device, the lock nozzle illustrated in Figure 2 has disposed within the inner end of the hollow shank 8 a ball 34, which ball 34 closes the mouth of the shank 8 on back fluid pressure from the valve l through the open chamber 35 in the casing I0.

In actual operation the valve shown in Figure 2 is attached rst to the low pressure container then valve shown in Figure l is attached to the high pressure container.

A variation in the device is shown in Figure 3 which a coil spring 31 is disposed about the compressing the conical.

pin Ila between the head lia of the nozzle head I3a and the pin head 23a. A ilexible washer 3l is of the same diameter as the pin head 23a and is supported against the under side thereof by the spring 3l, or by being cemented thereto, as illustrated in Figure 3. On full depression of the piston head 23a by operation of the cam lever 21a the washer 38 assumes the position, shown by the dotted lines X and Y on the upper rim of the flange |9a, thereby tightly closing the chamber 32a against the escape of any fluid.

It is thus seen from the foregoing description that I have perfected a device which will permit the passage of any nuid from one container to another without any danger of escape of the fluid. As previously stated, this is most important when dealing with poison gases..

It is, of course, understood that I do not wish to be limited to the exact disclosure as herein made, but. hold myself entitled to make such changes therefrom as fairly fail within the scope of what I claim.

The invention described herein, if patented, may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon.

What I claim is:

In a lock nozzle, the combination of a nozzle housing consisting of a cylindrical tube of uniform diameter open at its upper end and provided l0 with an internal annular flange at its lower end; a resilient sealing ring within the lower end portion of said housing immediately above the aforementioned ilange; a nozzle head slidably mounted within said housing and longitudinally shiftable with respect thereto, the nozzle head including a lower annular ilange adapted to bear against the upper end of the resilient sealing ring in order to compress said ring; a valve operating pin mounted on said nozzle head and longitudinally shiftable with respect thereto; said valve operating pin including an enlarged head portion in slidable relationship with the inner surface of the cylindrical housing tube; a. manually operable cam secured to the nozzle housing and operatively engaging the head of said valve operating pin; the entire structure being characterized by the provision of a conical yieldable resilient sealing gasket interposed between the head of the valve operating pin and the nozzle head, the arrangement being such that the force of the cam exerted on the head of the valve operating pin will compress the sealing gasket and simultaneously be transmitted through said gasket to the nozzle head to force it downwardly in the valve housing; thus compressing the aforementioned sealing ring to secure the nozzle in leak-proof relationship on the end of a valve stern.
