ROTARY STEAM ENGINE.
IIERRIS OGDEN, OF NIEADVILLE, PENNSYLVANIA.
' Leners Patent No. 84,371, dated Nambe '24, 186s.
MRVEIENT IN STEAM-ENG'mES.
. n schedule :sten-ca to in uw Leners imam; and making pm of uw im@ To all whom it concern:
Beit known that II, Fnnnrs OGDEN, of the city of Meadville, in the county of Qrawford, State of Penusylvania, have .invented a 'new and improved Rotary Steam-Engine and I do hereby declare that the following isa full'and exact description of the same, reference being had to the .accompanying drawings, and the letters of reference marked thereon.
Figure 2 is a perspective view of the same, showing an external view of the engine with all its parts ad-f justedin working order.
.A A are the two halves, each-having arecess, B, one inch, more orless, turned in its inside face, which recesses form, when the two halves A A, are secured together, the' steam-space or cylinder, Athrough farther in, making it tight, when so worn as to allow the steam to escape.'
The abutment D has a cavity. inthe side, and revolves once atevery revolution of the piston `G, in such ajmanner as to allow the latter to pass under, and then immediately closing down behind it, shutting off communication with the exhaust-port b.
Theextended portion'l l' of the piston O is shown parted in the drawing, and put together with tenons, and `fastened together by rivets; the tenons having loss motion in the rivet-holes, and spiral or other springs behind them, in order to pack themselves 'againstthe abutment, as at l', allowing steam tobe let on when the parts C and -D reach the position shown in fig. 1,. and continuing thus until just before the packing vit 'of the piston reaches `the exhaust-port b', when itis shut oiby the valve G. l
t Power is transmitted to the main shaft E by the arm J,'whieh passes, through a holeinthe ring m, up into the piston.
The space through which the arm J passes in revolving is closed by the ring m, the latter being supported by a short flange projecting from each of the halves A A, and revolving with the arm J.
The ring m has a bearing with the abutment AD, and the two roll together.
The piston is packed on the'top,` with steam packing.
The main shaft E is supported by pillar-blocks F F, and is connected with the valvesD and G, by means n, and the two ends of the upright shaft H and the bevel-gear wheels a a,
c c, and e e. l The steam-chest l', within which the cut-oli' valle is seated, has exhaust-ports ff At the tcp `these exhaust-portsunite in one' exhaustpipe. By this construction the ports b andI b are alternately opened and closed as the reverse valve K is placed in dilierent positions.
Through the bottom of the steamchest I there is a groove with its sides parallel, and the bottom of the groove parallel with the sides of the thimble h, and intothis groove'is .fitted the piece g, steam-tight.
The thimble h is cut away, as shownin g. 3, between the ends, which areconnected bythe piece h. Up into this thimble extends the piece g, which forms 'a steam-joint at the-ends'with the thimble h, and also against the plug-valve G. The pieceg,` the thimble h,
and the valve G, are pushed in until they are tight, andare kept in place by a pressure of steam on their large ends. y
The steam enters by the steam-pipe j, (see 6g. 2,) into the .centre of the valve G, and passes through the slot i, (see iig. 4,) in the side, and also, through k and b, into. the.cylinder betweeutheabutmeneD-:and
the piston O, forcing the latter around in the direction of the arrow.
The piece g, thimble h, and plug Gform a variable cut-o valve.
In the position shown in fig. 1, theengine takes steam through about ive-sixths of its revolution, or until the slot i, revolved by the gear c c, passes around .in the direction of its arrow, andis closed by the port h of the thimble. l
If the thimble h is turned by the lever M, segmen# tal gear L, and pinion S, in the direction of its arrow, steam is shut olf sooner, andthercby'the steam may be graduated.
Thus if the lever M is moved untiLthe pin 1J comes' into the hole q on the quadrant, the engine takes steam through one-half its revolution. If'the pin pis moved to fr, it takes steam through one-quarter, Ste., and allows the steamv to expand. through the remainder of ,the revolution.
The reverse valve K has two openings, 0 O', which will cover one of the ports, f f,and one of the ports, k'
and k', at the same time. (See fig. 1.),As shown inthe drawing, k is brought into communication with b, and If the slide-valve K is moved to the right by the lever N, and the arm O connected by a journal, T, the exhaust f will be brought into communication with b, and k with b', letting' in the steam on the opposite side of the abutment D, reversing the vmotion of the engine.-
v When the valve K leaks from wear, the steam-chest y I set down with the screws t t. If the valve K is so moved that the pin inthe lever N comes into the middlevhole inthe quadrant P, the ports 7c and k' will both be closed, thus making a throtl tle of the valve K.v
The halves A A are both fastened to the bea-plate Q by a key, U, through thev bottom of their flanges.
The shape of the halves and thermg m overcomes all Iateral pressure on the shaft E. Thiis the objet 3. I cl'aim the vthimble hand the plug-valveG, conof their construction. Y 'v struetd as described. l v v The engine 'is connecte with Aother msitehinery by 4. Iclaim the steam-chestlonstructedasdescribed the fly-wheel R. 5.' I claim theval'ragemeut'of @epatite-designated A What I-el'aim as my inventi'onfand desire to secure in the foregoing`1clau'ses o f the claims', constructed :isy
