DUPLEX DIRECT-ACTING ENGINE.
SPECIFICATION forming part of Letters Patent No. 278,133, dated May 22, 1883.
Application mea Min-'ch en, resa. (No mmh-m To all whom it may concern:
Be it knownthat I, WILLIAM Il. GUILD, of the city of Brooklyn, in the county ot' Kings and State ot' New York, have invented a'new and useful Improvement in Duplex Direct- Acting Engines, ot' which the following is a speeilication.
My invention relates to that class of duplex engines in which the valve ot' each engine is Io operated from the movingI piston-rod ot the other engine; and the principal object of my invention is to simplify the mechanism em. ployed for transmitting movement from the piston-rod ot' each engine to the valve of the other engine.
The inventiolrcousists in the combination, in a duplex engine, with thecyliuders, pistons, piston-rods, and two valves-one for each cylinderot two rock-shafts extending through and 2o journaled in the sides of the valve chest or chests, connected one with each piston, and each extendingoverthe valveof theengine whereby it is operatedv and engaging with the valve of the other engine. By this vconstruction I am z 5 enabled to operate the valves properly and to greatly simplify the mechanism employed for the purpose. I prefer to'provide the steameylinders with separate induction and eduction ports to and from each end thereof, and I 3o then employ a novel combination of valves,
which are hereinafter fully described.
In the accompanying drawings, Figure l is a plan of a portion ot'a duplex engine embodyiu g my invention, the steam-chest, covers, 3 5 valves, and portions of the rock-shafts being removed, so as to clearly show the valve-seats. Fig. 2 is a vertical section on the dotted line fr, Fig. 1. Fig. 3 is a vertical section on the dotted line y y, Fig. l; and Fig. 4c is a vertical 4o section ofthe valve seat and valve of one of the engines on the dotted line z z, Fig. 1.
Similar letters of reference designate corresponding parts in all the iigures. n
A A' designate the two cylinders of the 4 5 duplex engine. They are here shown as made integral in one casting, and are surmountcd by a single steam or Valve chest, C, wherein are the two valve-seats D D. The steam or valve chest might be divided by a partition, or 5o two entirely separate chests might be provided;
but the construction shown is preferred because of its simplicity.
E E( designate the two valves of the engines, each engine having but a single valve. These valves, as here shown, are simple slidevalves working upon their seats D D; but their forni-is diiierent from that of ordinary slide-valves. In each valve-seat DD is a central exhaust port and cavity, a, andthe ports and cavities of both engines communi- 6o cate with a central cavity, b, from which extends the exhaust-pipe c. [n each valve-seat D D are separate induction-ports d and eduction-ports c to each end of the cylinder.
`The valve E is what I terni a double B- valve;7 it being provided with four cavitics,ff g g, the former of which, when the valve moves so as to project beyond its seat, control-communication between the steam in the chest C and the induction-ports d, and the latter of 7o which control alternately the communication between each eduction-porte and the exhaust port and cavity a. This valve gives steam in front ofit, or, in other words, when moved toward the right it will admit steam to the induction-pipe leading to the right-hand end of the cylinder A, and will place the eductionport e, leading from the left-hand end of the cylinder,in communication with exhaust-port (t.
The valve E is what is termed a single D- 8o valve,77 and has but one cavity, h. This valve admits steam behind it; or, in other words, when the valve is moved toward the right it will admit steam through the left-hand induction-port d to that end of the cylinder A', and S 5 will establish communication by its cavity h between the eduction-porte, leading from the right-hand end ot' the cylinder, and the exhaust-port a.
'F F designate two rock-shafts which extend 9e transversely through the chest C, and which are each journaled in a stuffing-box, t, in one side of the chest, and a bonnet or plug, j, in the opposite side ofthe chest. The construction of these shining-boxes rand plugs so as to form bearings forthe rock-shafts is shown in Fig. 2.
G G designate the piston-rods of the engines, and H H designate braces or tie-rods which connect the engine-cylinders in a well-known roo e Mense manner with their oppositely-arranged pump or other cylinders, (not here shown.)
Upon'the piston-rods G G'are secured crossheads or arms I l', which are guided on the braces or tie-rods H H', and which are connected by rods J J' with arms K K', xed to the portions ofthe rock-shafts F F' which project beyond the chest C. The rock-shafts are provided with toes 7c k', which engage with and serve to operate the valves E' E. The rochshai't F, which is operated from the piston-rod G ofthe engine-cylinder A, extends past the valve E of that engine, and has its toe 7c engaged with the valve E' of the engine-cylinder A'. In like manner the rock-sh aft F', operated from the piston-rod G', extends past the valve VE' and engages with and operates the valve E of the engine-cylinder A. Therefore it will be understood thateaeh exigirle operates thevalve ofthe other, as is usual in duplex engines.
By my invention I greatlysimplify the mechanism required for operating the valves of duplex engines iu which each engine operates the with each piston-rod, and each extending over the valve of the engine whereby it is operated and engaging with the valve of the other engine, substantially as and for the purpose described.
2. In a duplex engine, the combination,with the cylinders, pistons, piston-rods, and two valves-one for each cylinder-ot' a single valve-chest common to both cylinders and containing both valves, two rock-shafts extending through and journaled in the sides of the valvechest, and each connected by a toe with one ofthe valves, and connections between the piston-rod ot each engine and therock'shaft which is connected with the valve of the other engine, substantially as specified.
3. The combination, with the cylinders A A', the steam-chest G, containingtne two valveseats D D', each provided with ports a d d c e,
