FERDINAND S. RUTTMANN, OF PLAINFIELD, NEW JERSEY.
STEAM-ENGINE.
SPECIFICATION forming part of Letters Patent No. 410,451, dated September 3, 1889.
Application filed October 12, 1888. Serial No. 287,916. (No model.)
Be it known that I, FERDINAND S. BUTT- MANN, of Plainield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Steam- Engines, of which the following is a specification.
This invention relates to an improved rotary engine which may be operated with an elastic or non-elastic medium, and in which the steam-cylinders and pistons are located within the iy-wheel and rotated with the same, the rotary motion being imparted to said iiy-wheel and cylinders by straps connecting a stationary eccentric si'dewise of the fly-wheel, through which the main shaft is passed, with the cross-heads of the piston-rods of the steam-cylinder.
The invention consists of certain details in the construction of a rotary engine in which the cylinders, pistons, piston-rods,cross-heads, and cross-head guides are located radially to the center shaft of the machine and within the plane of the iiy-wheel, as will be fully described hereinafter.
In the accompanying drawings, Figure l represents a side elevation of my improved vertical longitudinal section on lines Qc Fig. l. Fig. 3 is an elevation of the opposite side of the engine. Fig. Il is a plan of the same. Figs. 5, 6, and 7 are vertical transverse sections respectively on lines y, e, and 7c, Fig. 2, drawn on alarger scale; and Figs. 8 and 9 are horizontal sections respectively on lines c c and Z l, Figs. 6 and 7.
Similar letters of reference indicate corresponding parts.
Referring to the drawings, A represents a fly-wheel, the hub of which is secured to a main shaft S, that turns in bearings a a of standards A A2, located at opposite sides of the shaft.
On the hub of the iiy-wheel A, and within the same, are arranged radial cylinders F, preferably three, so as to produce a uniform motion of the engine. The cylinders F are located equidistantly from each other and alternate with the radial arms of the flywheel A. The outer ends of the cylinders F are connected with the rim of the iiy-wheel A by means of parallel guide-rails ff, which are Fig. 2 is av securely bolted to the end flanges of the cylinders and to the iiy-wheel, and which serve to guide the cross-heads jl! f, to which the piston-rods f2 of the pistons F are pivoted, as shown clearly in Fig. 2. The pivot-pins f3 of vthe cross-heads f2 are extended laterally beyond the rim of the ily-wheel A, and are connected to strap-rods H, which are applied by circular straps or bands h to a stationary eccentric C, which is formed integral with the supporting-standard A. The main shaft S passes through the stationary eccentric() and extends at both sides of the standards A A2, so as to be adapted for transmitting power from either end of the shaft.
To the opposite standard A2 is applied the steam-chest, with its supply and exhaust pipes, the reversing-gear, and the cutoff valve. The steam-chestD is provided with a transverse partition d, which divides it into two compartments or chambers T and U. The chamber T is provided with a steam-supply pipe t, and the chamberU with an exhaust-pipe u. The cylinders F communicate by passages z' in the fly-wheel A and main shaft S and port t" with an annular channel L, that is arranged in the standard A2 around the shaft S, said channel being divided into two semicircular parts by fixed abutments m m, of which one is located around the upper part and the other around the lower part of the shaft S.
A cylindrical reversing-valve O is located above the upper abutment m and provided with ports r and s, which connect the annular channel L, respectively, with the chambers T and U of the steam-chest D. The ports fu and s are arranged at right angles to each other and communicate with the channel L at opposite sides of the upper abutment m. The lower part of the exhaust-port s is made wide enough so as to communicate with the upper end of the annular channel L and with the exhaust-channel Q, as shown in Fig. G.
The annular channel L communicates, further, at both sides of the lower abutment m by means of ports p19 with an annular exhaustchannel Q, which is concentric to the channel L and arranged to communicate at its upper part with the exhaust-port s in the reversing-valve O and at the lower part at each side of the lower abutment m with sep- IOO arate exhaust-passages p p ,each of which is provided with stop-valves. (Not shown in the drawings.)
In the annular channel L are arranged intermediately between the abutments m fm. longitudinal cut-off bars b b, which are connected to semicircular guide-plates b', that are guided in recesses b2 of the supportingstandard A2. The bars b b form with the plates b the cut-off valve of the engine. One of the guide-plates b is provided at its circumference with cogs or teeth, which mesh with a worm-screw b3, that is Aapplied to a spindle b4, provided With a hand-wheel b5 at the outer end, as shown in Figs. 4c and 5. For the purpose of changing the positions of the cut-off valve b b the spindle of the wormscrew b3 may also, be connected with a suit.- able governor (not shown in the drawings) for the purpose of automatically regulating the speed of the engine to any desired degree ,correspondingly setting the cut-off valve The spindle of the reversing-valve O is provided at its outer end with a lever 0', by which the valve O may be turned on its axis and the position of the ports r and s relatively to the chambers T and U and channels L and Q changed. This action reverses the engine by converting the chamber T into the exhaust-chamber and the chamberU into the live-steam chamber.
When live steam is admitted successively into the cylinders F, the pistons F and the cross-heads f of the piston-rods are moved radially in outward direction, so that by the action of the connecting-rods H, which are strapped to the stationary eccentric C, rotary motion is imparted to the ily-wheel A, main shaft S, and the parts connected with the same. The steam passes from the live-steam chamber' T and the port r of the reversingvalve O into the annular channel L, and from the same through the port c" and the longitudinal channel 1l of the shaft S into the cylinders F. Live steam is supplied until the port e" has passed the first longitudinal bar b of the cut-off valve. After the port- 11 has passed the lower abutment m the steam is exhausted from the cylinder F through that part of the annular channel L which is located below the transverse bar b at the opposite side of the shaft S and through the exhaustchannel Q and exhaust-port s of the reversing-valve O to the exhaust-chamber U and passed out through the exhaust-pipeu. After the 'port il has passed the bar b of the cutof valve the exhaust-.steam passes directly through the annular channel L above said bar to the exhaust-port s, chamber U, and exhaust-pipe u. 4
When the engine is to be run continuously in one direction without requiring to be reversed, the exhaust-steam may be passed through the pipes p', the valves of which may be opened, so as to give a freer exhaust. The advantages of my improved rotary engine are, that by locating the cylinders, pistons, piston-rods, cross-heads, and crosshead guides within the plane of the iiywheel a very compact construction of the engine is obtained, while hardly any packing of the parts is required. Rotary motion is produced by the strap-connection of the cross-heads with the stationary eccentric,
which is located outside of the ilywheel.-
All the parts can be readily inspected and the engine be quickly reversed and Worked at different degrees of speed by the cut-off arrangement, so that the same is adapted to a wide range of application in the arts.
Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination of a central shaft, radial cylinders mounted on said shaft, a flywheel concentric to said shaft, guide-rails connecting the cylinders and iiy-wheel, crossheads connected to the piston-rods of the cylinders, a stationary eccentric surrounding the shaft, and strap-rods applied to the stationary eccentric outside of the plane of the fly-wheel and pivoted to the cross-heads, substantially as set forth.
