ONOFRIO ABRUZZO, OF NEW YORK, N. Y.
IMPROVEMENT -IN APPARATUS FOR CONDENSING AIR.
Speciiication forming part of Letters Patent No. 70,934, dated November 19, 1867.
To all whom it may concern:
Be it known that l, O Noraro ABRUZZO, of New York, in the county and State of New York, have invented a new and Im proved Pump for Oompressing Air; and I do hereby declare that theibllowingis a full, clear, and exact descri ption thereof, which will enable others skilled in the art to 'make and use the same,
reference being had to the accompanying drawings, forming part ot' this specitication.
The drawing represents ascctional elevation ot' my invention.
Similar letters of reference indicate corresponding parts.
'lhis invention relates to a new arrangement for compressing air in such a manner that the air can be compressed to an indefinite degree by hand, by any auxiliary small power, or by the engine in motion.
The invention consists in arranging a series of vessels and providing each one with a separate pumping apparatus. When the apparatus ot' the tirst vessel is set in motion it will compress the air in all the vessels to a certain degree, according to the power of the pumping apparatus, and to the rapport between the two volumes of air contained below the piston at the end of its upward and downward strokes, which volume determines the compressing power of pum ps.- 1t' the volume below the piston, when the same is at its lowest stroke, is, for instance, the twentieth part of that volume which is' below the piston at the end ot' its upward stroke, the pump will be able to compress twenty times the former volume at each stroke. When all the vessels are lled with such compressed air the apparatus of the second vessel is set in motion and compresses the air in all the vessels except the rst, so as to divide the air which was contained in the first vessel without using any more power than was used for compressing the air by the iirst apparatus, as the compressed air ot' the rst vessel presses upon the piston of the pumping apparatus.
A represents the first air-vessel, connected in any suitable manner with the lower part of a pump-cylinder, B, in which a valve, C, is arranged, said valve opening inward. The vessel A is also connected with the upper part of anotherpump-cylinder,B,the1owerpartofwhich is connected with a second air-vessel, A'. The latter is again connected with the upper part of a third cylinder, B", which, at its lower end, connects with a third air-vessel, A", tc. As many air vessels and pumps are used as there are degrees ot' compression required, the division of the atmospheres required by the power of one pump giving the number of pumps and vessels. The valves G C C, Src., in the cylinders all open inward, so as not to let any already compressed air escape. In each cylinder is a piston, D D D, &c., each piston being perforated, and having a valve opening'inward, as shown.` Each piston is operated by means of a suitable piston-rod, E E' E, 8vo., as shown.
When the operation begins the piston D is set in motion and compresses the air in all the vessels to a certain degreesay to twenty atmospheres, more or less-according to the poweremployed and the capacity and compactness of the pump, as before said. When the air in all the vessels A A A, 86e., is compressed to so many atmosphers as can be compressed by each stroke of the piston-say twenty atmospheres-the second piston, D, is set in motion and will compress still further the already compressed air from the first vessel. rlhe piston, when-moving up, will not meet with any resistance from the compressed air, as the valve in it opens during the upward stroke; but as soon as the piston is moved down it will have to compress the already compressed air. The air'from the tirst vessel, pressing upon the piston, counteracts as much ot' the pressure from below as its own compression amounts to-that is, if by the first pump the air was compressed to twenty atmospheres the said twenty atmospheres will press upon the second piston, and will thereby take ott' twenty atmospheres pressure from the work to be performed-and so the piston will compress the air to twenty atmospheres more than it was compressed by the first pump, and thus the process can be continued, ad infinitum, until the air is sufficiently compressed for certain purposes. Such air can be used for driving vessels or engines of any kind, and will by a less dangerous and a more convenient motion than the steam, and with insignificant cost, do better service and be more adaptable to the requirements of the present and future genera,- tons than the motors nowr in use.
