Be it known that I, JOSEPH RYAr-of the city and countyof St. Louis, in the State of Missouri, have invented a new and improved Single or Double-Acting Combined Air and Steam Siphon; and I do hereby declare that thc following is a full and exact description thereof, reference being had to the accompanying drawings, and to 'the letters of reference marked thereon. 0f said drawings I Figure l shows the Siphon in a. series of vertical central sectional elevations, thus: the part included in the bracket marked A,Sl10Ws the section aty 2, of fig. 2; the part included in the bracket marked A3 shows the section at y1 21, of iig. 2; the partjincludcd i'n the bracket marked A4 shows thc section at gf ze, of iig. 2.

The nature of my invention has the following general features: In raising water by air pressure in the steam Siphon, the partial Vacuu'in formed by the condensation of the steam is vitiated by air leaking into it, thus diminishing'the effective action of the Siphon. I therefore seek to perfect and preserve the attained partial vacuum by providing a packing or smiling-box arrangement wherever valves are necessary, which shall bc virtually airtight. This is effected, as hereinafter especially set forth, by a iluid packing. Secondly, after water has been raised it must be discharged against air pressure. This in common siphons is overcome by the action of a current of steam simply. I aid this current of steam by introducing a current of air, and in such manner that the steam'current imparts to the air current a part ofits velocity, thereby giving the air current a propelling action, aiding the discharge of water. Now as in the air action there is no appreciable loss by condensation, itwill be seen that this improvement is effective and valuable. The steam current, moreover, imparts, by transmission, to the air current a portion of its heat, which, by expanding the volume vof air, increascsthc velocity of the air current and affects beneficially thewatendischarging action. In a detail feature the nature of my invention consists in so arranging the parts of my Siphon that while drawing from a single supply pipe it may discharge water from one or two discharge pipes, or, as I shall hereafter term it, be single or double acting.

To enable others skilled in the art to make and use my improved Siphon, I will r.proceed to describe its construction and operation.

` Iconstruct the housing A of cast iron, brass, or other suitable material, and of the peculiar Shape pre' sented in the drawings, the same being in its parts composed of rounded hollow cylinders and hollowvglobes, as best shaped for aueconomical resistance of pressure and for reducing to a minimum the frictional resistance against the flow of water. The part ofthe housing marked A1 is at its lower end a immersed in water to the depth indicated by blue linesin figs. 1 and 2. The neck part A5 is vlengt-honed .according to the height to which the water shall be raised; for instance, vin a ship the flange a1V rests thc whole apparatus and secures it in the usual water-tight manner to the deck, the neck pieces A5 being then of suilicient length to allow ato rea-ch to the bilge Water, the parts A2, and especially the several hand-wheels, being then easily accessible to the operator standing on deck- The lowest bulb B is halvedl at b, the parts being joined in a water-tight manner by screwthreads or by common flanges. Between the halves is inserted the diaphragm plate Zz, which allows water to pass its perforations, but prevents the ingress of such impurities as will injure parts above. The lower part of B forms the seat for a gl'obevalve,'b2. Of this the balli?2 is made of a wooden body, coated with vulcanized rubber, gutta pcrcha, or some equivalent substance. This coating will secure awater-tight fit of this valve when closed, and as thewear will affect the ball 122, and not so much the metal seat, and this ball can easily be replaced, I hold that this arrangement will be beneficial. I The plate b1 serves, furthermore, to limit the rise of the ball b2. The bulb B connects by 'a short neck with the bulb C, which contains a throttle-valve, as shown in hori zontal section in fie. 3. The bulb C connects by a screw joint, or by iianges, in a watertight manner, with' the rounded cylinder C1. Through the axis of, this passes the valve stem c. As will beY hereafter more fully shown it is of importance to prevent air to leak into the bulb C. I have therefore made the following arrangement: I screw into the inner surface of the joint-piece of the lbulb C the cap nut el; into this again is screwed the packing nut c2, leaving between the two the piace c3 to be iilled by cotton yarn or other" suitable packing material. By screwing the cap nut c2 into c1 the` packing is pressed against the valve stem securing the water-tight passage of' thc steam; but lest this packing should allow -air to leak 4through lv lill the cylindrical space ci with some liquid, usually water, and this will, moreover, preserve the packing'in c" in :1- moist .cned condition. The liquid filling c4 is poured in bythe funnel pipe'c. This is .shown enlarged in g. 4. ,There are small annular openings, extending from the inner edge of Cl to thc, top of c, to allow the escape ot' the ali' in lilling c4 with fluid. The Z'screws on the 'upper end of. c, The'stcm c passes on through `the neck part' of Cl, there being at c6 another packing, secured by the cap nut c7 in a 4water-tightmanner. This thrrittlc-valve being usually some twenty feet below the station of the operator, in order to actuate` it seeiire 'to thc-end of lthe stem c the worm gear-wheel es, which is turned by the worm or screw on thesl1aft-e." This'sh'aft passes up to the station of the operator, and is there turned by the hand-wheel-c. The shaft 0 finds its support in the bearings of the forks of the standard c, whichuissccured around the neck-piecc of Cl. New as the worinwheel must remain in Contact with worin on e9, the stem cannot at this point move horizontally. I therefore construct it of two parts, c, and cm'being male and female screws, so that by turning c and preventing it from horizontal motion by the pin am, which bears in the annular slot of om and is fast in the neclr of Cl, the part c, is drawn forward, opening the valve passage, or forced backward, closing it. It is here immaterial which ot' thc parts c, and c are male -or female. IThe tw'o branches ol the neck `part A5 connect with the upper part of the bulb C. Each of these branches consists of a pipe, D, and a root-piece, DI; this latter will usually con ncct'immediately with G. The joint between D and D1 I construct as follows: ythe upper end of Dl is widened, forming the conical space d so as to pass the flange d1 on D and rest it securely on D; the intervening space is then iilled by some (to water) impervious substance, lead, iron,.cement, orrsome other. Next above the flange al is the chamber A, which connects with-the priming apparatus hereafter described. vThis chamber is divided equally by a partition wall, a?, 4which extends from' the ange alto the upper end of the apparatus, dividing it into two separate parts. Next above are the globes E, both equal in construction and operation, and on diicrent sides ot the partition a2. These contain throttle-valves, with liquid packing similar to that in the cylinder C1. These valves are actuated by the hand-wheels e?, and these simply turn the stems e, which being provided witl` screw-threads where they pass the cap nuts el, will move horizontally, opening or closing the valve passages. Next above are the double-bulb chambers F. These are at vtheir front side shaped to discharge the water. The mouth-pieces Fl are narrowest in area of section about atf, and widen toward the end fl, thus facilitating the easy discharge of water. At the rear end of F are the cylinders F2; these are closed byv the caps f1 and contain an inner cylinder f2 which again at their rear ends are closed by the throttles f3 these threttles f3 are operated through the stems fr and hand-wheels ji, The stems nd a bearing in the support fo through which they pass with screw-threads, so that in turning the hand-wheels f5 the stems receive the necessary horizontal motion. The cylinders FZ are connected each by pipes with the steam chamber Gr; this connection is opened or closed by the common stop-cocks g. The steam chamber Gr receives steam direct from the boiler through the main supply pipe gl. Furthermore, G is connected by a pipe with the chamber A6. This pipe has a stopcock, g2. t l

I will now proceed to describe the Aoperation of my improved siphon in single action. All the throttlevalves on the one side of the partition a2 remain and are closed. The throttle-valve in C isclosed, that in E is open. When the priming-cock g" is opened steam passes' into all parts above the lowest throttle-valve, (in 0,) and drives out the air;l this effected, close the throttle-valve in E. The steam condenses between the two valves, and if now the valve in C is opened', the water in rising fills the partial vacuum to the valve in E. If now the valve E is opened, the air pressure from above would force the water back were it not that the ball b2, which Vwas raised by the water in its upward passage, now drops and prevents the return new. Moreover, if new the steam cocks g permit steam to pass into the outer chamber of F2, the steam current passing forward carries thev air with it, and'also by condensation creating'a partial vacuum, causes the water toA rush forward to the discharge atfl. As was observed, the action of the Siphon to raise water depended on the formation ofthe partial'vacuum between the throttle-valves in C and E; hence it is important toprevent any leakage of air at these valves, which could vitiate the vacuum thus formed, and to effect this I have introduced the liquid packings as heroinbefere described. It has been observed that the air pressure from the discharge f1 opposes the passage of the water after its rise te the throttle in E. To aid the steam current in overcoming this air resistance I'introduce an air current, thus: when thesteam current through F" is in action, open the throttle f3 thus permitting air v to pass into the cylinder f2; this will rush forward to ll the partial vacuum created bythe steam current, surrounding it, and thus the air current will act upon-the water, forcing it to discharge atj'i. Moreover, the air being surrounded by steam will become heated; it will expand; and to permit and facilitate this expansion the tube f; may contain the vglobefl this globe presenting also a large surface for the heating action of the surrounding steam to take elect upon. This expansion of the air necessarily causes'an increase of its velocity, and momen-tum, making the action upon the water still more elective. The air tubes f2 may extend out even with the tubes F2, or they may extend farther or lbe shorter, (the latter positions being marked by red lines according as the action of the air current'may be desired. The shorter the air tube the sooner the steam current carries the air forward, but the less is gained by air expansion. 0f course the amount of air admitted into the cylinderfz can be closely regulated by the throttle-valvcsjl, I believe that above thirty per cent. of the useful eilect produced iscaused by the introduction of the air current in the tubes In order that I may the benefit of an expansive action of the steam in F11 when higher pressures are used, Imake the inner surface of F2 wider at the discharge end. This is shown by red lines in fig. 1. The flow of water will necessarily be continuous until the supply of steam is checked and the throttle-valves closed.

When the siphon shall be double acting, the throttle-valve in C is, as before,flrst closed and steam admitted on both sides of the partition a2. Then the throttle-valves in E being closed the vacuum forms in both branches ofA, between C and E. Then the throttles in E on both sides `opened and the steam (first having been cut off nt g2) permitted to pass in both tubes Fl, will cause the water to discharge from both discharge pipes. 'Elie air-current action is brought tobear in both tubes f2 Havingl described my said improvement, what l' claim as my invention, and desire to secure by Letters Patent, is
