STEAM-AC'TU'ATED VALVE.
SPECIFICATION forming part of Letters Patent No. 279,378, dated June 12, 1883.
Application filed March 5, 1883. (No model.) i
-.To all whom/it may concern:
- inafter described, and pointed out in the claims.
In the drawings, Figure 1 is a vertical horizontal sectional view of a steam-chest with the valve and valve-stem removed. Fig. 2 is a view of the bottom of the steam-chest, showing the'location of theinduction and exhaust I portson the line where the steanrchest joins the steam-cylinder. Fig. 3 is the same view of the steam-chest as shown in Fig. 1, with the addition of the valve and valve-rod in their respective places. Fig l is an end view of the steam-chest with the head removed. Fig. 5 is a plan view of the valve. Fig. 6 is a plan view of the valve stem or rod.
A represents the steam-chest; a, the head of the same. 1
B is the main valve, actuated by steam admitted thereto by the auxiliary valve 0.
The steam-chest has two longitudinal cylindrical and parallel openings that extend the entire length of the steam-chest, the upper and larger one, B, forming the seat for the valve, the lower and smaller one, C, forming a seat for the valve-rod. The seat B has a chamber surrounding it at the center, that terminates in a square cavity below, forming the exhaust-port b, the said exhaust-port bisecting the seat 0'.
Surrounding the seat B, and on either side of the'exhaust are the chambers b and b the former branching around the seat 0 and leading to the respective ends of steam-cylinder below, the latter extending to either end of the steam-chamber above.
On either side of the chambers 11 are portions of the seat B, forming bridges or divisionwalls that separate them from the chambers b and the exhaust I).
By reason of the reciprocating motion of the main valve B the annular grooves D in the valve are made alternately to spanthe bridges on either side of the chamber 1), so that the said chambers b and theirattached passageways into the cylinder are alternately connected with the steam-chamber, forming an induction-port and with the exhaust-port I).
The auxiliary valve 0 has a long annular groove or depression, 0, in the center, that is embraced by the yoke (1, extending from the center of the valve, and that moves freely on the said depression.
Atequal distances on either side of the depression c are the annular grooves c and 0*. The grooves c are for admitting steam alternately to the ends of the valve to give a proper reciprocating motion to the valve. The grooves c are for exhausting the steam thus used in moving the valve and at the moment when the motion of the valve is to be reversed.
The steam for moving the valve as aforesaid is conducted from the steam-chamber by means of the passage-way a, made preferably in the ends or flanges of the steam-chest, although they might be made in the heads a. These passage-ways are crossed by the auxiliary valve, and are opened or closed as the auxiliary valve presents at these points the grooves c or the full size of the valve. 7
The steam used for moving the valve, as aforesaid, is exhausted from the respective ends of the valve through the small passageways F. (Shown partly in Fig. 1 and partly in leaving only sufficient vapor to cushion the valve.
The operation of my device is as follows The auxiliary valve 0 is caused to move in either direction and at the proper time by an arm m, "A U attached to the piston-rod butting against adj ustable collars attached to the said valvestem. WVhen by this means the auxiliary valve is moved to the right hand the groove'c on the left hand will, by means of the passageway a, admit steam to the left-hand end of the valve and cause it to move to the right, thereby causing to be opened the inductionport on the right and the exhaustport on the left, which will of course reverse the stroke of the pump. Then on the returnstroke the auxiliary valve is moved to the left, the same movement of parts in this direction occurs that has just been described as occurring on the righthand stroke.
In starting the pump, if from the accumulation of condensed Water about the valve or from any other such temporary cause the valve does not move promptly by the action of the steam operating on the end of the same, the valve will, by means of the shoulders a; the ends of the depression 0 coming in contact with the yoke d, be carried along so as to perform its function of opening the ports and re versing the pump, as aforesaid.
What I claim is' 1. The combination, with the main valve seat and its chambers, of a main valve having annular grooves constructed and arranged substantially as described of the auxiliary valve, and means, substantia 1y as described, for operating the main valve by the auxiliary valve, substantially as set forth.
2. The combination, with a main valve provided centrally with a projecting yoke, of an auxiliary valve provided with an annular groove Within which engages the yoke 011 the main valve, substantially as set forth.
3. The combination, With the valve-chest provided with passageways a and F, of the auxiliary valve provided with the annular grooves c and 0 substantially as set forth.
In testimony whereofl sign this specification, in the presence of two Witnesses, this 8th day of February, 1883.
ILLI AM HAEHULEN.
