STRAIGHT-WAY VALVE.
SPECIFICATION forming part of Letters Application filed March Patent No. 281,228, dated July 17, 1883.
16,1883. (No model.)
To aZZ whom; it may concern:
Be it known that we, J osEPH H. Bacon and XVILLIAM H. PAIGE, of Detroit, county of Wayne, State of Michigan, have invented a new and useful Improvement in Straightay Valves; and we declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to makeand use it, refer ence being had to the accompanying drawings, which form a part of this specification.
This invention relates to improvements in that class of straight-way valves wherein two valve-disks having wedge-shaped backs are forced to their seats by a plunger having a wedge-shaped end operating between the disks.
Our invention consists in the combination of two valveplates wedgeshaped on their backs with a wedge-shaped plunger adapted to be reciprocated between the plates, and means for operating the plunger, the bearing-surfaces of the plunger being constructed on the arc of a circle, and the adjacent faces of the valveplatcs being constructed to correspond there with, whereby accurate adjustment of the valve-plates to their seats is obtained.
The invention is illustrated in the accompanying drawings, in which Figure 1 is a vertical central sectional view of a valve embodying our invention. Fig. 2, detached views of the plunger and the two valve-plates; and Fig. 3 is a horizontal sectional view through the valve-chamber, the valve-plates, and the plunger.
In the drawings, A represents the valveohalnber provided with suitable valve-seats, c and a.
A A represent the couplings.
B is the bonnet.
G and 0 represent two valve-plates. These plates are constructed with wedge shaped backs, being thicker at the bottom than at the top. They are also provided near the top with suitable lugs, c.
D is a wedgeshaped plunger, screw-tapped to receive the screw-cut valve-stem E, said valvestem operated by a hand-whee1, E. The wedge-shaped plunger is provided with suitahis shoulders, d, adapted to engage with the lugs 0 upon the valve-plates, said shoulders constructed to allow the desired amount of play in the operation of the plunger before engaging with said plates. These valveplatcs being constructed in separate parts, as shown, may be readily located in position in the val ve- 5 5 chamber, as it is evident that by removing the bonnet and loosely engaging said plates about the plunger the whole may be dropped into their location, the plates resting upon suitable supports, a and a", in which position they will be forced upon the valve-seats by forcing down the wedge-shaped plunger by means of the screw-cut valve-stem.
It is obvious, since the valve-plates and the plunger are wedge-shaped, that by forcing down 6 5 said plunger between the plates any desired pressure to force the valve-plates upon the valve-seats may be readily secured. It is also evident that by reversing the operation of the va1ve-stem the pressure of the plunger upon said plates will be relaxed as the plunger is drawn backward, and when the shoulders (I of the plunger engage with the lugs c on the val ve-plates, the valvepl ates will be lifted and the valve-chamber will be opened.
The end of the plunger D, besides being wedgeshaped, has its two opposite bearingsurfaccs constructed in the are of a horizontal circle, and the adjacent faces of the valveplates are provided with cavities corrcspond- 8o ing. to the form of the bearing-faces of the plunger, whereby an accurate adjustment of the valve-plates to the valve-seats is obtained.
The usual stuffin g-box F and follower Fghaving a flange, f, and the cap or nut G, are pro- 8 5 vided on the bonnet to make a tight joint for the valve-stem.
\Vhat we claim is In a straight-way valve, the combination of two-plates, wedge-shaped on their backs, and 0 having lugs c, a wcdgeshaped plunger having shoulders d to engage said lugs 0, adapted to be reciprocated between said plates, and mechanism for operating the plunger, the bearing-surfaces of said plunger being constructed in the arc of a circle, and the adjacent faces of the valve-plates being formed to correspond therewith, substantially as described.
In testimony whereof we sign this specification in the presence of two witnesses.
