VALVE FOR COMPRESSED GASES.
SPECIFICATION forming part of Letters Patent No. 783,024, dated February 21, 1905.
Application filed August 26, 1903. Serial No. 170,798.
To all whom it may concern.-
Be it known that I, ABRAHAM BEEKMAN Cox, Jr., of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Valves for Compressed Gases, of which the following is a full, clear, and exact description.
The object of my invention is to produce a valve for readily controlling the flow of gas compressed into tanks and cylinders for the purposes of transportation and storage -such as oxygen, carbonic-acid, and other commercial gasesand particularly to produce a valve in which the handle and other actuating parts can be readily removed, so as to prevent damage to the valve in transportation.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures represent corresponding parts in both views.
Figure 1 is a cross-section of one form of my complete valve, some of the parts being shown in elevation; and Fig. 2 is a horizontal cross-section of the needle-valve ata point coincident with the line 2 of Fig. 1.
indicates a portion of the end or other part of the cylinder or tank, to which the valve is attached by being screwed into the neck 11 or by any other suitable means of attachment.
12 is the valve-body, which is attached to the tank or cylinder, as above set forth, and which is hollow and has an internally-screw-th readed portion 13, into which is screwed the needlevalve 14, which has its lower extremity terminating in a conical point 15, which fits accurately into a conical orifice in the valvebody 12.
The tip of the conical point 15 protrudes through the valve-body 12 and when the needle-valve is screwed upward allows the gas to pass into the lower portion of the said valvebody 12. The screw-threaded portion 16 of the needle-valve 14 is provided with a channel 17, (shown in Fig. 2 in section,) which allows the gas to pass upward into the upper part of the valve-body 12.
While I have shown a channel made by milling a groove through the said screw-threaded portion 16 of the needle-valve 14, I do not limit myself to this or to any particular form of channel or to any number of channels. I may, for instance, make my needle-valve 14 tubular in cross-section, with suitable ports for the passage of the gas.
The upper end of the needle-valve 14has a stem 18, which is squared in the same manner as the usual winding-arbor of a clock, and the removable key-cap 19, which is screwed to the Valve-body 12 or otherwise attached in such a manner, as to be secure and yet readily removable is provided with a key 20, shaped like an ordinary clock-key, passing through the upper part of the key-cap 19 and adapted to register with the squared stem 18 of the needle-valve 14.
The key 20 is provided with a suitable handle 21 and at the lower portion of the stem 22 is expanded into a section of a cone, which is fitted accurately into a similar depression 23 in the upper part of the key-cap 19. \Vhen the key 20 is moved upward, the conical surfaces 22 and 23 will fit together, and thereby prevent the escape of gas around the stem 24 of the key 20. Instead of this form of construction a stufiing-box may be fitted to the projection 25 on the upper part of the keycap 19, so as to surround the key-stem 24.
The key-cap 19 is provided with a threaded projection 26, to which may be attached any suitable tube for conducting the gas, and the passage 27 leads to the interior of the key-cap 19. The projection 28 is intended to afford a means for more readily screwing down the key-cap 19 when grasped by the hand of the operator and to obviate the necessity of using a wrench or spanner. A suitable washer (not shown) may be provided in order to make the joint between the key-cap 19 and the valvebody 12 gas-tight.
The parts are so proportioned, as shown in Fig. 1, that when the key-cap 19 is properly screwed down the key 20 will always engage the squared stem 18 of the needle-valve 14. When the needle-valve 14 is screwed to the uppermost limit of its movement, the key 20 will rise and the surfaces 22 and 23 will fit tightly together. This is the position of the valve for charging the cylinder with gas. The
The valve, as shown in Fig. 1, can be used in all respects like the usual gas-tank valve; but when it is desired to prepare the gas-tank for shipment the key cap and key can be readily removed and instead can be substituted a screw-cap of any ordinary form of construction, which I have not shown for the sake of simplicity, thus making it impossible for the needle-valve 14; to be unseated or damaged, so as to cause leakage of gas, and affording, a means for preventing gas leakage should the needle-valve be imperfect.
Instead of the needle-valve 14L I may substitute any suitable form of valve known to the art without departing from the spirit of my invention, and it will be readily apparent that I have devised a simple and durable valve and one which by reason of its position partially within the tank is well protected from damage by rough usage.
Having fully illustrated and described my invention, what I wish particularly to claim is l end, the said casing having its body provided with external threaded portions of two diameters whereby a shoulder isformed between the two threaded portions, a spindle threaded in the bore of the casing and fitting against the seat in the end thereof, and a cap threaded to fit the outer part of the casing, said cap having an outlet-bore forming a continuation of the bore of the casing.
