Application March 15, 1949, Serial No. 81,516
This invention relates to new and useful improvements in apparatus for analyzing gases, and it is among the objects of the invention to provide a gas manifold and valves which shall be of simple construction and accurate in use.
The invention will become more apparent from a consideration of the accompanying drawings, constituting a part hereof, in which like refershoe characters designate like parts, and in which.
Fig. 1 a front elevational view of a modified form of gas analysis apparatus;
Fig. 2 a top plan view of the device shown in Fig. 4;
Fig. 3 a front elevational view, broken away, of a portion of the manifold of the gas analyses apparatus; and
Figs. 4 and 5 cross-sectional views, respectively, of a special type of valve employed for controlling the gas flow in the manifold.
With reference to the several figures of the drawing, numeral l designates a frame having a valved manifold section 2 at the top, a cross partition 3 for supporting pipettes 4, 5, 6 and to, below which is mounted a bracket 1 for support ing a washing bottle 8 having an inlet 9 and an outlet 10, the latter being provided with a valve The partition 3 extends downwardly at 3a to form an elongated chamber for a graduated tube l2 which is used for measuring the volumes of the gas samples to be tested. The graduated tube or burette I2 is immersed in a water bath confined in a transparent cylinder I3 closed at the ends with rubber stoppers l4 and i5, respectively. The purpose of the water bath is tomaintain the gas in the burette I! at a constant temperature and therefore constant volume. Connected to the bottom of the burette I2 is a flexible hose l6 leading to a vessel l1 filled with a confining liquid, such as water or salt solution ing 22, Fig. 1. The member 20 is provided with a channel 23 communicating with a gland 24 with the connections 2|. The flow of gases through the glands 24 from the measuring burette to the pipettes and the washing fluid is controlled by valves consisting of a flexible rubber or neoprene strip 25 which is displaced as shown in Fig. 5 by a plunger 23 operable in a cylindrical bore 21 of the metal casting 19, the
plunger being actuated by a thumb screw 28. t
Coil springs 29vare provided to prevent seating of the strip 25 when the plunger 25 is inopen 1 Claim. (Cl. 277-60) 2 p position, as shown in Fig. 4. Where the glands 24 open into the meeting channels 23, a special valve seat 30 is provided which effectively seals off the opening when the valve is closed, without, however, obstructing the meeting channel passage 23, as is clearly shown in Fig. 5.
The valves in Fig. 1 of the drawing are designated by the reference characters 31, 3'2, 33, 34.
It is evident that by. the use of a manifold having a meeting channel common. to all of the valves andby the employment of the plunger or cylinder valve with a yieldable strip, leakage and breakage incident to the use of the conventional form of glass cock valves is eliminated.
Although one embodiment of .the invention has been herein illustrated and described, it will be evident to'those skilledin the art that various modifications may be made in the details of conthe principles portion having a plurality of depending cylin- I drical members with glands communicating with a common meeting channel, said channel having cylindrical recesses concentric with the glands of said'depending members, a second body portion of complementary dimensions to said first-named body portion, and a resilient strip disposed between the abutting faces of said portions, the second-named body portion having cylindrical portions in register with the cylindrical recesses of the first-named body portion, a cylinder in each ofsaid portions and adjusting screws abutting the ends of the cylinders whereby upon displacement of the cylinders, portions of the resilient strip are displaced in the recesses of the first-named body portion to effectively seal the gland with which it is in register, said first-named body portion being counterbored in the gland passage for receiving springs to restore the flexible strip to its normal o en position when I the screw acting on the cylinders is retracted.
