STEAM -VALVE.
srncrrxca'rxoiv forming part of LettersPatent No. 734,885, dated July 28, 1903. Application filed December BOA-90:2, Serial No. 13i.19i2. (No model.)
i To all whom it mag concern.- Be it known that I, THOMAS J. KIERNAN, a citizen of the United States, residing at O- lumbia, in the county of Richland and State of South Carolina, have invented certain new and useful Improvements in Steam-Valves;
use the same.
and I do hereby declare the following to be a full, clear,-and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and My invention relates to improvements in steam-valves; and it consists of certain novel features that will be hereinafter described and claimed.
, Referenceis had-to the accompanying draw ings, in which the same parts are indicated l by the same letters throughout both views.
Figure 1 is a longitudinal vertical section in the plane of the axis of the cylinder and shows the valve and. interior of the steamchest. 2 2 of Fig. 1 and looking in the direction of the arrows.
A represents a cylinder, and B a steamchest, inclosing the valve N, mounted on the shaft K.
squared where it engages the valve, or it may be keyed or rigidly attachedto the valve in any convenient way. The valve N is sub stantially cylindrical in form and rocks between curved bearings m onlthe valve seat.
. M and g on the balance-plate Q. The steamport a opens into the passage m in the valveseat, and the port 0, opens into the corre sponding passage m. a is the exhaust-port, which connects with the exhaust-passage n in the valve and also with the curved exhaustchamber 41 out into the valve.
The valve is provided with steam-passages n and n and is alsocut away, as at n and M, to permit the passage of live steam to the cylinder when the valve is in theproper position, as" indicated by the arrows in Fig. 1'. On top of the valve is the balance-plate Q, which plate moves in a guideway in the block P, and the said block is held in place by means of bolts R. The top of the balanceplate carries four strips S, forming a square,
Fig. 2 shows a section along the line This valve-shaft is preferably.
shown in that figure, live steam will enter through the passages 97. and 11 into the pas sage m and thence through the porta. into the cylinder, whileexhaust-steam will pass through the passages m, 11?, and n into the exhaust-port a If the valve be rocked to the opposite direction, the cycle of flow of steam will be reversed.
It will be obvious that the ports a and a may be placed at any desired position relative to the ends of the cylinder. It will'be seen that the steam is supplied through both the top and bottom of the valve at the same time, and by this arrangement the valve may be made to operate after being rocked through a very short distance, thus insuring a quick feed and a quick exhaust of the steam. The
.double exhaust-passages in the valve area feature of special importance. The valve is intended especially for use for lOCOlIloliVes and Where it is difficult to secure a quick enough exhaust. By duplicating exhaustpassages in the valve, as shown, a far more rapid flow of exhaust-steam is secured. This is'especially desirable for all high-speed engines and for use with pistons having a short stroke.
Various other advantages of the herein-described valve and mechanism will suggest themselves to any one skilled in the art.
Having thus described myinvention, what I claim, and desire to secure by Letters Patent of the United States, is
1. The combination with a cylinder provided with steam and exhaust ports and a curved valve-seat, of a substantially cylindrical valverockingonsaid valve-seat,stea|npassages in the side of said valve, and donble exhaust-passages in the base of said valve, substantially as described. y p
2. The combination with a cylinder provided with steam and exhaust ports and a curved valve-seat, of a substantially cylin- (lrical valve rocking on said valve-seat,steampassages in the side of said valve, and a curved curved valve-seat, of a substantially cylindrical valve mounted transverse to the cylinder and rocking on said valve-seat, withdoublesteam-passages in each side, and double exhaust-passages in the base of said valve, substantially as described.
5. The combination with a cylinder provided with steam and exhaust ports and a curved valve-seat, of a substantially cylindrical valve mounted transverse to the cylinder and rocking on said valve-seat, with steam-passages in the side of said valve parallel to the axis thereof and extending through the valve-body, double exhaust-passages in the base of said valve, with a curved balanceplate-bearing on the top of said valve, and a guide-block mounted in the steam-chest and holding said friction-plate in place, substantiall y as described. I
6. The combination with a cylinder provided with steam and exhaust ports and a curved valve-seat, of a substantially cylindrical valve mounted transverse to the cylinder and rocking on said valve-seat, with double steam-passages in the side of said valve parallel to the axis thereof, a curved exhaustpassage and an exhaust-chamber in the base of said valve, with a curved friction-plate bearing on the top of said valve, anda guideblock mounted in the steam-chest and holding said friction-plate in place, substantially as described.
, In testimony whereof I aifix my signature in presence of two witnesses.
THOMAS J. KIERNAN.
