Specification of Letters Patent.

Patented Sept. 1? 1912.

and useful Improvement in Needle-Valves,

of which the following is a specification, reference being had therein to the accompany-= ing drawings, forming part thereof.

My invention relates to valves and relates particularly to such valves as are adapted for use on portable tanks or storage reser-Y use.

in claims. r

The illustrated embodiment of my invention comprises a pin member 1, for'attaclr voirs for containing gases under high pres-- 15 sure for illuminating purposes, such, for example, as actylene gas. One of the com-i mon uses of such port-able gas tanks is upon; automobiles, for supplying illuminant to thef lamps thereof. For such uses the gas storage tank is necessarily comparatively small, to save weight and space, and must there-; fore be'charged to an extremelyhigh pressure to supply sufficient illuminant for thef desired length of time,

-. The smallness of the storage reservoir and,

the high initial pressure of the stored gas introduce the difliculty in the use of the gas that the pressure falls rapidly, necessitating very frequent adjustments of the valve to preserve the lamp flame of proper size; and the chief object of my present invention is? Other objects and advantages will appear; from the following description.

My invention includes means controlled by the high pressure fluid for controlling the amountof fluid supplied to the point of;

My invention V also includes various de-= tails of construction and combinations off parts. s i

I will now describe the embodiment of'i my invention illustrated in the accompany-Q ing drawing, which Shows a longitudinal;

central section of the complete valve, to-. gether with portions of contiguous parts, and will't-hereafter point out my invention ment to a source of uid under pressure, for example, a contalner 16, a portlon only of which" is shown,: and a valve-carrying cap member- 2, shown as united by screw threads to the plug 1. .The plug lvhas a longitudi- 6 and forms a continuation'of the servicenal service-passage 3 which communicates,

through the valve mechanism hereinafter described, with a transverse service-passage 4 provided "in the member 2, the direction of flow of fluid when used being as indicated by the arrows. A service-duct 5, leading to the point of use and shown as broken away, is connected to a nipple formed on the member 2 by an ordinary screw connector-ring passa e 4. 7

Delivery of fluid through passage 4 and duct 5 is automatically controlled by a compensating valve mechanism which in turn is controlled by the pressure of the high. pressure fluid in the container 16 and passage 3. Such mechanism comprises a iap'hragm 7 clamped between the members 1 and 2 and made fluid-tightby a packlug-ring 8 which may be of alummum.

The member 1 is cup-shaped or hollowed out at its top to form a chamber 9 constituting a pressure-chamber or diaphragmchamber, of which the diaphragm forms one wall, and the member 2 is also shown as slightly hollowed out or cup-shaped and in coiiperation with the packing-ringB forms a free space or receiving-chamber 10 above the diaphragm. The passage 3 forms an inlet for the pressure-chamber 9 and an outlet therefor is formed in a valve-seat 11 3 carried at the center of the diaphragm.

The valve-seat 11 is shown as secured to the diaphragm by a nut 12, and the joint is made fluid-tight by a washer 13, the valveseatbeing in the form of a tubular stud.

A tapered valve proper or needle valve 14 issupported in the member 2 and coacts with the valve-seat 11, which has a flaring opening for receiving the tapered portion the valve. The valve 14 has a threaded engagement with the member 2 and has a handle portion extending to the outside, through an ordinary packing gland as shown, for manual adjustment of the valve relatively to its seat. The nut 12 extends upward some distance from the diaphragm in the form of a tube or sleeve and is guided at its uppermost portion on the shank or stem portion of the needle valve 14, so as to assure at all times a proper seating of the ,valve, as otherwise the diaphragm might at times buckle or twist and prevent proper coaction or cotiperation of the valve and valve-seat. The bore of the tubular nut 12 is reduced at its upper portion for guidance on the valve and is rovided with counterbores for exit of fluid paming the valve. The upwardly-extending portion of the nut 12 is loosely received in a bore 15 in the member 2 and which communicates with the service-bore 4 therein.

In the operation of the device the valve may be opened more or less or completely closed ofl at any time by adjustment of the valve proper 14' in the usual manner.

When the valve'is firmly closed the head of tially and that the valve l iis firmly closed against its seat. As the valve14= is moved in its opening direction, by unscrewing, the

valve-seat 11 will follow the opening movement of the valve for a certain distance and until, the tension of the diaphragm becomes equal to the pressure of the fluid in the pressure-chamber 9, the valve of course remaining seated or f closed up to this point. Further opening movement of the valve 14 will separate it from its seat and permit flow of fluid from passage 3 out through service-duct 5 to point of use. The valve may now be opened to a greater or less extent to permit more or less fluid to pass as desired. When the valve has once been adjusted no further adjustment or attention will be necessary,-as the initial adjustment a serves also as a final adjustment, even However, if the size of the valve-opening remained the same, less fluid would pass therethrough and the light would accordingly grow dim as the pressure. in the contamer became reduced from usage of fluid therefrom. This tendency is oflset by the compensating action of the valve mechanism. As the pressure of fluid in the container becomes reduced the pressure of fluid in the pressure-chamber 9 is correspond mgly less and failing to longer balance the tension of the diaphragm, an inward movement of the diaphragm takes place, separating the valve-seat." 11 more widely from the valve 14, thus compensating for the re-- duced pressure by providing a larger open mg, whereby substantially thesame quantity of fluid is delivered-to the point of use irrespective of whether the pressure in the container is high or low. I Y

Inthe drawing the device is indicated as in use, the outlet-valve 14 being represented as open and the diaphragm 7 as bent outward by pressure of fluid in the pressurechamber 9 and controlling the escape of the fluid in accordance with the amount of pressure in the container 16 as explained above- It is obvious that various modifications may be made in the construction shown and above particularly described within the principle and scope of my invention.

I claim 1. A valve mechanism comprisinga pressure-chamber provided with an inlet and an outlet, a diaphragm forming a Wall of the pressure-chamber, a valve-seat carried by the diaphragm, an outlet valve coactive with the valve-seat and having a stem extending outward, and a guidefor the valve-seat carried by the diaphragm and guided by. the

valve stem. 4

2. A valve mechanism comprising a pressure-chamber provided with an inlet and an outlet, a diaphragm forming a wall of the pressure-chamber, a valve-seat carried by the diaphragm, an outlet-valve coactive withv the valve-seat from the outside of the pressure-chamber, the co-action of'thevalve and its seat being controlled by the diaphragm, and means for imparting opening and closing movements to the valve inde pendently of'the diaphragm, the valve-seat being adapted to rest on the bottom of the pressure-chamber when the valveis firmly closed by said means, whereby the diavphragmv isrelieved of excessive strain.

3. A valve mechanism comprisinga pressure chamber provided with an inlet and an outlet, a diaphragm forming a wall of the pressure chamber. avalve seat carried by the diaphragm, an outlet valve coactive with the valve seat from the outside of the pressure chamber and having a stem extending outward, the coaction of the valve and its seat being controlled by the d1a-' phra 'm, and a guide for the valve seat carried by the diaphragm and guided by the valve stem, the valve stem being manually operable for imparting opening and closing movements to the valve independently of the diaphragm and the valve seat being adapted to rest on the bottom of'the pressure chamber when the valve isfirmlyclosed by manual actuation.

In testimony whereof I aflix ture in presence of two w tnesses.
