Renewed February 12, 1934 7 Claims.
This invention lrelates to devices for supplying carbon dioxide in gas or liquid form under pressure. and more particularly to means for facilitating the production and transporting of such 5 carbon dioxide. i
It is the present custom to supply carbon dioxide in liquid form in heavy metal containers under a pressure of 1000 pounds to 1200 pounds per square inch. The carbon dioxide is converted l into the liquid form at a central plant., and transported to the places where it is to be used in metal containers. Obviously, sucha method of transportation is inconvenient and expensive and undesirable, especially in view of the high l pressure of carbon dioxide. It is well known that carbondioxide maybe easily solidified and compressed into blocks of any size, and that when solidified carbon dioxide sublimes, the gas has approximately 500 times the volume of the solidied carbon dioxide. y It is also known that a quantity of solidified carbon dioxide may be placed Ainto a suitable container and allowed to sublime or change to the liquid state and produce a high pressure. However, such practices have been carried on in compartments which do not enable the replenishing of the supply of solidified carbon dioxide without materially affecting the pressure of the liquid `carbon dioxide already formed.
VIt, is therefore an object of this invention to.
A further object is the provision of a container for converting solidified carbon dioxide into a liquid or gas, in which container is provided a safety valve to allow the escape ofthe gas when the pressure exceeds a predetermined amount.
These and other advantageous objects are attained by the novel construction, combination and arrangement of parts hereinafter described and shown in the accompanying drawing, constituting a material part of this disclosure, and in which: l
Fig. 1 is a sectional View of the container for converting solidified carbon dioxide into gas or liquid.
Fig. 2 is a sectional view taken on line 2-2 of Fig. 1.
Fig. 3 is a sectional view taken on line 3 3 of Fig. 1.
Referring to the drawing, in Fig. 1, is shown -cpen the passage 17 and allow the gas to escape (C1. ca -91.5)
a metal container 5, having walls strong enough to withstand at least 2000 pounds per square inch pressure. The container 5 is preferably cylindrical in shape, and is provided with a cover 6, hinged thereto. At a short distance 39 from the open end of the container is mounted Ya plate ll, having shoulders upon which rests a heavy wire grating .'l and` forming a small chamber 8 in which is placed a definite weight of solidified carbon dioxide 9. The chamber 8 is provided also with a safety valve 10 to accommodate excessive pressures, the valve 10 being of substantially the same. structure as the safety valve 16, hereinafter described. Y
The plate 11 has a central aperture 14 through 1Q which gas passes into the main compartment 21. The plate 11 also has a wedge-shaped recess adjacent the aperture 14, the recess 12 being shaped to receive a wedge-shaped valve plate 13 to close the aperture 14 and prevent the escape of gas from compartment 21 when the cover 6 is raised to replenish the supply of solidified carbon dioxide f in chamber 8. The valve plate 13 has a threaded stem movable in a threaded portion of the plate 11 andthe wall'of container 5, the valve being controlled by a hand wheel 15.
Mounted in a wall of the compartment 21 is a safety valve 16 having a passage 1'? communieating with the compartment'll, which passage isnormaily'l'ield closed by a conical nose 18 of a block or plunger 19 having arecess receiving one end of a compression spring. When the pressure in the compartment 21 exceeds the strength of the spring, the nose 18 is moved to through an aperture 20 in the valve casing.
Gas or liquid carbon dioxide may be drawn -from compartment 21 through an 'aperture in the bottom of container, which aperture is controlled by a valve 22; or it may be drawn through tube'26, which communicates with a casing 24 containing lumps of calcium chloride 25 to remove the moisture from the gas before it is finally drawn through either of the pipes 27 or 28. The casing 24 is mounted directly on the container 100 5 by means of lugs 23, which are integral with the container and the casing. The pipes 27 and 28,may be used to supply gas under pressure simultaneously to a carbonating apparatus for soda fountain use or to a machine for converting the 105 carbon dioxide back into small discs of solidified carbon dioxide.
In operation, a definite weight, for example lbs., of solidified carbon dioxide is placed in the chamber 8 and rests on the grating 7. The 110 ratus.
dioxide 9, the latter sublimes, and inasmuch as' carbon dioxide has a density greater than air, the gas passes downwardly through 'the aperture 14 into the compartment 21. By using a definite quantity of solidified carbon dioxide. a substantm definite pressure of ges or ngnt carbon 1i--4 oxide may'be obtained. y
When it is desired to replace the supply of solidified carbon dioxide `in the chamber 8, the
ABy providing a safety valve 18, the pressure of the gas in the compartment 21, may be controlled and would prevent accidents due to negligent maintenance of the device.
From the above description it will be seen that there has been produced a simple and effective apparatus for conveniently supplying carbon dioxide under pressure without necessitating waste or losses during the manipulation of the appa- The foregoing disclosure is to be regarded as descriptive and illustrative only, and not as restrictive or limitative of the invention of which obviously an embodiment may beV constructed including many modifications without departing from the general scope herein indicated and denoted inthe appended claim.
