REVERSING SLIDE-VALVE.
SPECIFICATION forming part of Letters Patent No. 628,396, dated July 4, 1899.
Application filed April 8, 1898. Serial No. 676,8fi0. (No model.)
To all whom it may concern:
Be it known that I, HENRY DAMERELL, of Lndlow, in the county of Livingston and State of Missouri, have invented a new and useful Improvement in Reversing Slide-Valves, of which the following is a specification.
My invention relates to certain improve. ments in slide-valves for steam-engines; and it consists inthe peculiar'construction and arrangement of parts designed to provide a simple, practical, and efficient valve for reversing an engine, as will be hereinafter more fully described. with reference to the drawings, in which- Figure 1 is a longitudinal section through the cylinder, steam-chest valves, and its operating devices. Fig. 2 is a side View of the valve-shifting mechanism, with steam-chest in section. Fig. 2- is an edge view of the levers n 10 Fig. 3 shows the position of the parts of the valve after reversing.
In the drawings, X represents the steam-cylinder, 0 its piston, and Y the steam-chest.
The steam-cylinder has the two inductionports J J and the intermediate exhaust-port K. Within the steam-chest, over the ports J, J, and K, slides the compound valve. This valve consists of a distributing-valve A and an independently-movable section W, interposed between the ports of the cylinder and the distributing-valve A. The distributingvalve A is independently adjusted bya stem H, and the slide-section W is provided with a sleeve R, by which it and valve A are reciprocated from the eccentric. The stem H passes concentrically through the sleeve R, the latter being provided with a stufling-box a where it emerges from the steam-chest and the sleeve B being offset to one outside of the steam-chest (see Fig. 1) in the form of an arm R, while the central stem H, which is attached to the distributing-valve, extends straight through the offset, which is provided with a stuffing-box a at the point where said stem H emerges from the offset. This makes two independent connections outside the steamehest for working the two parts of the compound valve together or separately, as hereinafter described.
The distributing-valve A has a large exhaust-chamber L in it opening inwardly in the middle and also through portsZZ near its ends. There are also formed in the inner side of Valve A two induction-ports C O, which are located between the central exhaust-opening L in valve A and the end openingl and Z. These induction ports 0 0 open into the steam-chest to admit steam through the passages D E F G into the ports J J of the cylinder.
The distributing-valve rod H is jointed to a lever n fulcrumed at g to a rocking arm 19 (see Figs. 2 and 2%) which at its lower end is hinged, as at to a suitable fixed point. The bottom end of lever n is jointed to a shifting rod 5 worked by lever 3 The upper end of arm 10 is connected to eccentricrod V connected to an eccentric which rocks arm 19 and causes the reciprocation of both parts of the valve W and A in the normal working of the engine.
The operation'is as follows: In the position shown in Fig. 1 live steam from the steamchest enters opening 0 and passes, through E and port, J, into the side at of the cylinder, forcing the piston in the direction of the arrow, and the steam on the side at passes out J, through G to Z, and then through central exhaust L, through B, to exhaust K. When the rods R and H are together moved by the eccentric to the right, the valve A W shifts to the right and the port D is over J, F is over J ,and live steam entering at 0 passes through F to J to the side m of the piston, forcing it in the other direction, and the steam on side n passes out J, through D and l, to L and through B to the exhaust K. Now to reverse the motion of the engine, the relation of the distributing-valve A and slide-section W is changed through the agency of the rod H and sleeve R, and for this purpose distributingvalve A is slid to the right on the part W, as shown in Fig. 3. This is efiected through lover s, rod 5%, and lever 71 and as the upper end of n in Fig. 2 is thrown to the right it pulls rod H and distributing-valve Ato the right on the intermediate part W. Now the two parts A and W of the valve reciprocate as before from the action of the eccentric, but with this difierence in the arrangement of the parts that C is over G, which is an inductionport, D is exposed in the steam-chest and is the other induction-port, O and Z are dead or inoperative ports, and Zis over E and is an exhaust-port. This, it will'be seen, changes ports D and G to live ports and portsF and E to exhaust-ports, which changes the direction of the motion of the engine.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. The combinationwith a steam-cylinder having a central exhaust and two end ports; of a compound reversing-valve consisting of a flat slide-section arranged to move on the ports of the steam-cylinder, and having five passages through it arranged as described, a sleeve connecting with said slide-section and emerging from the steam-chest through a stuffing-box, a distributing-valve section arranged to move directly upon the slide-section and having central exhaust-chamber, end exhaust-openings, and intermediate induction-openings, said distributing-valve section having also an attached rod extending low, a concentric rod attached to the other part of the compound valve and issuing from the steam-chest through the sleeve, a lever n jointed at its upper end to said rod, fulcrumed at its middle to arm p and connected at its lower end to a rod and adj listinglever substantially as and for the purpose described.
