IMPROVEMENT IN norAaYsTEAM-BNGINES t i 't i @the tlnhnle attrib tu in there Entert man animating putt nf `tip: anni.` y
Be it known that I, A. S.HARLAN, of Bloomington, in the county ot'A McLean, and State of Illinois, have invented a new-and improved Rotatory Steam-Engine; and I do hereby declare that` the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. In the drawings- Figure 1 is a longitudinal vertical section, and l Figures ,2 and Bare end views of'the interiors of the cylinders a a. A,
Thisinvention belongs to tha't class'of steam-engines termed rotatory, in which E the steam` acts at once, t y in theproduction of circular motion, upon a revolvingpiston, without the use of any` intermediate mechanism,` t auch as the crank, for deriving a circular from a. rectilinear motion. V
It-consistsof two cylinders on one shaft, the latter being provided with two projecting ribs, one within cach cylinder, which serve as pistons, said ribs being on opposite sides of the shaft, and said shaft being enlarged, as to the parts within' each cylinder, as hereinafter fully described. i
To enable those skilled in the art to Ina-ke and-use my invention, Iwill now proceed te describeitscmstruction and operation.v o
A A represent two cylinders, of equal dimensions, placed end to end. B represents a shaft,`passing lon- B. The object proposed ,to be accomplished by the cylinders C is the expulsion of the steaml from the central to theouter parts of the main cylinder, through the operation of centrifugal force. VIt is supposed that the inner cylinders in their revolution cause those portions' of the steam in contact with and in the neighborhood ofthem, also to revolve with such speed as to overcome the centripetal force and cause the particles to seek"` y vade` the cylinder. The steam crowded to those parts of the main cylinder, neart'he surface, operates more t strongly against the outer sides of the pistons D, at the points where ,its force is most advantageously applied. The power of .a`given number of pounds of steam is thus practically increased.` DLD reprcsentjthe' pistons,"` being ribs attached lto the inner cylinders G, and extending nearly to the interior surfaces o f the m'ain cylinders A. As shown at iig. 1, these ribs are on opposite sides of the shaft B, in order that by the time the'steam t passing out of the eduction-port has ceased to act upon one, it may have commenced acting upon the others piston, which has just passed the induction-port in the other cylinder. Auuiform rotation of the shaft is` Vthus insured. The steam enters by the supply-pipe e, which terminatesin vtwogbranches leading'to the-two cylinders A A. The branches are provided with valves G Gr, whichare connected by rods b b, to eccentric` straps al d, which surround eccentrics on opposite sides of the shaft B. ,Thus thc valvesopeu and close the j.
tion. E'represcuts large flaps, hung on pivots Iz, which rest in grooves madein theends of the jchambersc,`
the cylinders A, and of suiciehtiwidth to-reach the surfaces of the inner cylindersC. By means of the rods F,
a bar on the outside of the chamber k, so as 'to be `both operated at once. To reverse thelengine, it is` only Partition within each cylinder, and directs the steam to one side or the other of thepiston, according as the` Bap 'is on one side or the otherof the induction-port.-
represents the escape-pipe, into which the eductionports open. p v
i i .Having thus fully described my invention, what I claim as new, and desire to secure byLetters Patent, `is-` 1. The arrangement ,of the flaps E so as to slide in grooves' from one side of `the induction-ports to the 2. The arrangement of the eduction-ports'S of the cylinder so Vas to release the steam after a semi-revolution? p t A. s. HARLAN.` Witnesses: l
