OPERATING VALVES FOR STEAM-PUMPS.

Speccation of Letters Patent No. 11,073, dated June 13, 1854.

1 To all whom it may concern Be it known that I, CHAs. A. WILSON, ot' the city of Newport, county of Campbell, and State of Kentucky, have made a new and useful Improvement in the Mode of VVOrking Valves for Steam-Pumps; and I `do herebydeclare that the following is a full and exact description thereof, reference being had to the accompanying .drawing and to the letters and gures of reference t marked thereon.

port bored or cast in the smaller end of the same diameter of the steam pipe. This receiving opening runs in along the center lof said valve until it reaches the extreme edge of two ports which run across through the center of said valve, corresponding, with two ports which are in the seat one breadth of themselves below the center of said seat, so that when the valve is on its center the 'steam can not enter either of these ports in the seat so that when the valve moves either way itmustopen a port.

The exhaust opening of this valve is a flattened place or cavity on the lower side of said valve wide enough to cover the exhaust in thesea't and one of the steam ports,

at the same time so that the spent steam may escape freely. This escape opening runs down through the bottom of the seat and intoan opening which has its outlet in the side of the side pipe under the small end of said valve seat. The above mentioned ports which are in the seat run down sponding ports in the side pipe. The above L mentioned ports run across through the center of said valve and balance each other with the exception of the taperwhich causes them to have some pressure outward Von the valve and they being in the center on each side of said valve prevents them from pushing the valve to either side of said seat. Thepressure of the above mentioned port, or opening running along in the center of thevalve to the two above mentioned cross ports pushes the valve from its seat. This is provided` for by having two large lugs or ears cast on the sides of the large end of said seat directly opposite to each other, so that when a line is drawn through the center of those lugs it will cross the exact center of said valve seat. To these lugs two columns are screwed to the outer` ends of which is an arch in the center of which is an adjustable steel screw which screws against the end of the valvestem which is in the exact center of the large end of said valve, projecting out toward said arch. This stem may have a steel plug fastened in itfor the adjustable screw to screw against to prevent its wearing; this adjustable screw is used to adjust the valve so that it may work free under any reasonable pressure; on the large end of said valve are two jogs running in toward said stem,`near enough however to leave a recess between said steam and said jogs in which recess the boss on a lever fits; this vlever having an eye or hole through said boss which work on said stem and the boss in said recess;` these jogs are so arranged that when the lever is thrown to the right it catches on the upper edgeof t-he right jog and on the lower edge of the left one (the same to the left.) This lever is loadedalt'the top with balls a large one and a small one. The large `one is fastened to or on the top of the lever and the small one hinged to the top oflit,`so that when the large one strikes its resting place the small one falls or shackles over and catches the rebound of the Vlarge one, thus producing a dead stroke instead of having therebound which would be the case if there was but one ball. This lever is guided by and traverses in a slotted segment at its top end, this segment is cast on the two resting studs of the large ball. for about an inch down from the top. These hollows are filled with wood to whichare tacked or nailed india-rubber. This is to prevent the sound the ball would make: in falling. These" studs are screwed to the side of the side pipe.. Near the lower end of these studs are two bearings for a slotted rod towork in. The lower endof the above mentioned levervpasses through this slot in said rod.` The slot in this rod isequal to half the traverse of this end of the lever. This allows the lever when carried to its center to fall clear of all appendage with its weight and momentumagainst the jogs as'above jmentionedgthus :making sure` of These resting studs are hollow y40' stroke of the piston, so that when l knocker strikes these nuts it moves the rod 2 11 ,ove

the opening of the valve, the jogs being so arranged that the lever passes its cent-er someJ distance before it strikes them, unlike that of Hartins water meter, the tumbling lever of which has to drag after it the rod that gives it motion, mine falling clear of all appendage and having no fulcrum, the valve being the center of motion, the lever being loaded with two balls for preventing the rebound `the resting studs for the large ball; the jogs lbeing so arranged as to receive the power applied to open the valve instead of his slotted plate. In fact, the whole principlesinvolved in the two things differ so widely and there being applied to different purposes, that for which mine is intended his will not do. I think and feel convinced that mine is an improvement far superior to his and being used for a different purpose I cannot see any reason why I shall not obtain Letters Patent for it.

The above said slotted rod has attached toit by a flexible joint a rod which is attached to the upper arm of the tumbling shaft. This tumbling shaft is situated across the center of the stroke of the piston rod and has an arm running down through a slot in another rod which has two adjustable nuts on each end for the knocker to strike; this knocker is screwed on the piston rod with a pinching screw. It has a fork on one side of it pointing upward, which fork straddles the rod with the adjustable nuts on it. These nuts are jammed by having` ferrules on the rod equal in length to the traverse of said rod, against the outer ends of which other nuts are screwed. The distance between these adjustable nuts is something less than the the in the same direction that the piston rod is traveling, moving the lower arm of said tumbling shafts the same, and the upper `one in an opposite direction, pulling the rod attached to it, which pulls the lower end of the lever in the same direction, moving the upper end with the balls in the opposite way until it passes its center when it falls with its momentum and weight against vthe j ogs of the valve and opening it as yabove as stated. 'Fig 4 shows another way for this lower rod to be worked. This is done by letting vthe rod pass through the cylinder head and through the head of the pump, having the pistons ofthe cylinder and the pump to strike it alternately the same as the knocker does in the other. This rod has a long screw on'its centerso as to fasten on an arm between two nuts, which is also fastened to the upper slotted above mentioned, thus doing away with tumbling shaftsl and fixtures.
