Once you've determined which one of our freeze proof faucets best serves your needs, take a look at our instructional step-by-step video on how to install it.
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.

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. These errors in some instances involve loading of too large a volume of liquid, and in other instances too small a volume of product into the tank.

Then the tube itself would be expelled entirely from the tank, leaving an open hole through which the explosive fluid would be discharged to the atmosphere, causing fires and great damage to property, with occasional loss of life. An operator could see it; but the break or inadvertence could be corrected before any d-amage at all could result or would result. 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. Butane, the most commonly used of these somewhat similar fuels, is usually handled by allowing the relation ofninety per cent for liquid and ten per cent for gas. This gage then is offered as one of extreme safety and accuracy. The outside threads II of the topmost extension of the head 2 are designed to carry sealing cap I2, which has alower finished face, Underneath this face and resting on the shoulder I3 of member 2 there is a ring of packing Iii, provided so that when the cap is screwed down fast it seals the head against the possibility of ,any escape to the atmosphere of any fluid as may appear therein, such as might be present if packing IEI were to leak. This valve seat and this valve. 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. The liquefied petroleumV gases stored Y in the tank which carries this gage are quite volatile and usually exert considerable pressure. This gage then is offered as one of extreme safety and accuracy. When the tank is being charged with fuel there is a frequent, if not almost continuous reading of the gage. It is torbe recognized that this -is a slip tube gage; and because the tube is'required to slide up and down in its housing there would ordinarily be opportunity for leaks around the tube. The need for safety and accuracy has Vcaused its creation. Then a tiny Istream of liquid will appear and be discharged from the top of the gage.
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.
Therefore this safety plug 28 with its extremely small aperture or orifice 29, has been provided in the lowest extremity of the gage. It insures leaving an outage space r. 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. When the tank is being charged with fuel there is a frequent, if not almost continuous reading of the gage. The liquefied petroleumV gases stored Y in the tank which carries this gage are quite volatile and usually exert considerable pressure. John R. Immediately thereupon he restores the gage toits collapsed, closed, sealed and locked position. This gage did 'not answer the need for safety, so ever ,present in the handling and gaging of liquefied petroleum gases. One undesirable result of a completely filled tank was that when the liquid expanded it would be forced through the service line to the consuming appliances and cause the premises to catch tire. The inside thread 'I is made to carry a compression nut s. USA1 en. A further object is the provision of a gage which is exactly 'accurate in all of its readings, in that it will 'determine the level of fuel at 'the most minute differences in levels ofthe liquid in the tank. Immediately above the seat of valve I8 there is provided through the side wall of tube head I'I a discharge hole 22, through which the contents of the tank will discharge to the atmosphere while the gage is being read.
