MANIFOLD,
Specification of Letters Patent. Patented J 11118 27, 1922. I
Application filed October 11, 1920. Serial No. 415,965.
To all whom it may concern: I Be it known that I, HARRY F.,SM1TH, a citizen of the United States of America, re-' siding at Dayton, county of Montgomery, and tate of Ohio, have invented certain new and useful Improvements in Manifolds, of which the following is a full, clear, and exact description.
This invention relates to conveying systems, and more particularly to a divided manifold having means for preventing leakage, at the places of jointure, from one passage of'the manifold 'to another.
One of the principal objects of theinvention is to provide means associated with the ends of the sections of a divided manifold for preventing the leakage of the material conveyed by the manifold from a passage upon one side of a dividing partition to a passage upon the other side.
Another object of the invention is to provide an improved fitting for use in connection with purifying apparatus such as that disclosed in United States Patent 1,099,773 issued to me June 9th, 1914, which fitting has means associated with the dividing partition thereof to prevent the escape of impurity containing gas from its conveying passage into the passage conveying the clean gas.
Other objects and advantages of the invention will be apparent from the description set out below when taken in connection with the accompanying drawing.
In the purification of gas, particularly producer gas, as described in the patent above referred to, the drum containing the separator or extractor pad is normally mounted upon a fitting which comprises a divided manifold, the passage upon one side of the dividing partition connecting the drum upon one side of the extractor pad to a source of impure gas, and the passage on the other side of the dividing partition connecting the drum upon the opposite side of the extractor pad to the place of utilization of the gas. In other words, instead of using one pipe to convey the impure gas to the extractor andanother pipe to convey the clean gas from the extractor, it is the practice to use a single divided manifold, in which the impure gas passes therethrough upon one side of the dividing partition and the clean gas upon the other side of such partition. It has also been the practice to properly machine the flanges, provided upon the opposite ends of these fittings, for permittlng theirattachment to the ends of cooperating fittlngsor pipe sections, so that a substantlally gas-tight joint will be secured when, the fitting is in. assembled position. For ordinary operations the joint thus formed; is sufficiently tight. In many cases, however, as where extreme cleanness of the gas is desired, there should be complete prevention of any leakage of impure gas into the cleaned gas; for itis evident that appreclable leakage of impure gas through the place of jointure ofthe dividing positions of the manifolds into the clean gas side thereof will result in the delivered gas having an excessive quantity of impurity.
In order to prevent this leakage, or transfer, of material from the passage upon one side of the dividing partition into the passage upon the other side of the dividing partition, the apparatus is constructed as shown in the drawing, in which is illustrated, somewhat diagrammatically a fitting for receiving a drum or housing containing a separator or. extractor pad such as described in the above referred to patent, certain parts being broken away to more clearly illustrate the invention.
In the drawing the numeral 10 designates generally a fitting having flan 'es 11 at each end thereof adapted for attachment to correspondlng flanges 12 upon cooperating fittings, or sections of pipe or manifold, 13. This fitting 10 has a dividing partition '15 therein, which extends lengthwise of the fitting, dividing it into two passages 16 and 17. This dividing partition 15, when the fitting is in assembled position, that is, attached to the cooperating members 13,is in alignment with a corresponding dividing partition 18 which divides such cooperating members 13, forming a part of the conveying system, into passages corresponding to the passages 16 and 17 Opening through the upper wall'of the fitting 10 are two ports 20 and 21, the port 20 opening into the passage 16 and the port 21 into the passage 17 Surrounding the ports 20 and 21 is an upstanding flange 22 adapted to receive the base flange 23 of the drum 24. This flange 22 generally carries suitable looking or retaining mechanism which cooperates with the base flange 23 to hold the drum' 24 in assembled position.
As shown in the drawing, the space upon one side of the partition, for example the space to the left, is connected through'the port 20 and passage 16 to the generating chamber of the producer. The passage 16 therefore contains impurityladen gas. The space within the drum upon the other side of the partition 25 is connected through the port 21 to the passage 17, the gas within this passage 17 being therefore cleaned gas, more or less free from impurity.
The contacting surfaces upon the corresponding ends of the fitting 10 and the cooperating members 13 are preferably machined so that a tight joint may be secured through metal to metal contact of these contacting faces. In actual practice a differential pressure of about two pounds to the square inch exists upon opposite sides of the extractor pad 26, and, therefore, a corresponding differential pressure exists within the passages 16 and 1-7. Also the pressures within each of the passages 16 and 17 are normally above atmospheric. Under these conditions it is diificult to secure such a metal to metal contact as will entirely prevent the escape of gas from the passage 16 into the passage 17. To prevent the transfer of impure gas from thepassage 16 to the passage 17 a groove'is provided within the contacting faces of the dividing partitions 15 and 18, which groove is in open connection with the atmosphere. Any gas which tends to leak between the contacting faces of the dividing partitions from the passage 16 into the passage 17 will be trapped withinthis groove and thus will escape to the atmosphere.
Inactual practice, in order to make easier the construction of the fittings 10 and c0- operating members 13 and to facilitate assembly thereof, connecting bolts are used upon only two sides of the fitting, the fianges upon the other two sides, at each end, having no connecting bolts. It sometimes happens, because of this method of connecting that the contacting surfaces of the flanges having no bolts are not held in sufiiciently close .contaetto .prevent leakage therethrough. To take care of such leakage as might occur, the grooves 35 are provided in the flanges having no connecting bolts so that if desired, packing material may be tamped into place within these grooves to make the joint satisfactorily tight.
As shown in the drawing the contacting faces of the fitting 10 and of the pipes 13 are each provided with grooves which, when the sections of the manifold are in assembled position, register with each other. If desired the entire groove may be located within either the fitting 10 or the cooperating pipe sections 13, either construction being entirely satisfactory so long as a groove of sufficient size is provided to vent into the atmosphere all of the gas that may be trapped therein.
