Another gage which gave trouble and frequently leaked is the old-fashioned slipetube gage; and as heretofore constructed it discharged too much fluid from the tank while it was being read; and there was no way to sliptube occasional or continued leaks around the slip-tube itself, even though packing was used, sliptube. Sliptube this nut is firmly made up it will also hold the Vpacking in place, sliptube. The space thus left is usually ten per cent of the maximum capacity of the tank.

John R. Homer, Shreveport, La. This invention has vto do with a device for'in'dieating the level of liquid in a pressure vessel, and for determining the gas-filled space 'above such liquid, commonly called outage space. It is particularly useful in determining the quantum and character of the contents of a tank containing liquefied petroleum gas fuels, such as butane and the like. Grages have been used which are unsafe, 'delicate and easily damaged. For example, themagnetic float type gage is such a device. The iioat may leak, the gears become inaccurate, and 'foreign materials cause the magnetic Vneedle to stick, especially if the glass cover is broken. Another gage which gave trouble and frequently leaked is the old-fashioned slipetube gage; and as heretofore constructed it discharged too much fluid from the tank while it was being read; and there was no way to prevent occasional or continued leaks around the slip-tube itself, even though packing was used. This gage did 'not answer the need for safety, so ever ,present in the handling and gaging of liquefied petroleum gases.

March 20, H. In one aspect, it relates to apparatus for gauging liquefied petroleum gas in transport truck tanks. When filling tanks of transport trucks with liquefied petroleum gas LP-Gas current practice for gauging such tanks is to use a roto-gauge for determination of deliveries to the truck tank. Roto-gauges are often damaged through vibration and shock resulting from travel over roads and highways and thus become inaccurate. It has been found that in many cases serious errors have occurred in gauging liquid volumes loaded into transport trucks.

Use our Product s to quickly and easily place your order! II is a sectionalized elevation of the entire gage assembly. The side walls of the well are not threaded; and the lower extremity f packing nut 3 is 'finished in a concave form, the better to engage and compress the packing against the side wall of tube I. When the tube is the least bit-loose in its housing this fuel undertakes to escape around the-outside of the tube, either as a gas or as liquid. It is leak proof and allows cleaning and repacking of its exposed parts and mechanism while the storage tank is in operation. It is particularly useful in determining the quantum and character of the contents of a tank containing liquefied petroleum gas fuels, such as butane and the like. A 'further object is to provide a device for securely closing and locking the gage in place, when not in use. This tube head is threaded internally through the entire length of its vertical opening; and the upper part of the opening is made to carry screw valve I8. This cost effective support started a design trend that revolutionized the rooftop support industry. The tank is then filled to the required level which will indicate the gallonage delivered. It is particularly useful in determining the quantum and character of the contents of a tank containing liquefied petroleum gas fuels, such as butane and the like. A valued obj ect is to provide this effective secondary seal so that while it is in use the head of 'the gage can be removed, the packing nut unv screwed and new packing placed around the tube 'in the gage head without any possibility of a leak around the tube duringsthis operation of repackin'g, or while parts of the head are being Vrepaired or removed for cleaning. In the drawings the parts and details of the gage structure are referred to by numerals, in which numeral l is a small straight tube, suiciently long to pass through the top of the tank in which it is carried and the fittings thereabove, and extend almost to the bottom of the tank.

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings. Connect these fittings to Schedule 40 plastic pipe— they are the industry standard for residential and commercial low-pressure plumbing and water supply applications.

By han-d the operator slides the gage up or down in the gage head until the lower part of the gage is held at the required level. At that moment the iilling of the tank to the proper liquid level is coimplete. For instance if straight propane were used a greater gas space and a less liquid space would be provided for. Outageftube listhreaded on its upperexternal wall and is carried. Another diiculty with the older gages was that no provision was made for automatically determining, measuring and limiting the outage space so that it would not be filled with liquid. It is extremely dependable. III is a sectionalized elevation of al1 of the parts of the gage, severally and in order, except only that the tube itself is not shown in this iigure. Therefore, valve seat 5 has been arranged as an extension of the gage head 2; and the stop ringl has been'smoothly surfaced on its upper face and provided-with gasket material 2s which will co-act with valve seat 5 to constitute and to close a valve when the rtube is elevated in the housing. It continues to be safe even though these parts are broken off while the gage is fully extended. If the customer desires less than the full charge of a tank of fuel, the predetermined level to which the liquid is to be supplied may ;be ascertained by consulting a previously prepared chart which reveals the contents of the tank, inch by inch, and for fractional parts of an inch. USA en. A valued obj ect is to provide this effective secondary seal so that while it is in use the head of 'the gage can be removed, the packing nut unv screwed and new packing placed around the tube 'in the gage head without any possibility of a leak around the tube duringsthis operation of repackin'g, or while parts of the head are being Vrepaired or removed for cleaning. Immediately thereupon he restores the gage toits collapsed, closed, sealed and locked position. It is to be noted that the stop ring 25 is so constructed and arranged that the gasket 2B, which is supported on the upper face of the ring, will in fact press against, impinge and contact the annular projection on the lower face of housing 4, so that, when the slip tube is extended up- B wardly to its fxnost elevated position.
