Specification of Letters Patent.
Patented @cti a, 19MB.
To all whom it may concern:
Be it known that I, JULIUS R. TANNER, a citizen of the United States, residing at littsburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered new and useful Improvements in Non-Return Valves, of which the following is a specification.
My invention relates to what are usually known as non-return valves and has for its object the placing of the dash-pot outside of the valve casing where it will not collect sediment, and the simplification of the closing mechanism therefor.
Referring to the accompanying drawings, Figure 1 is a central vertical section through the inlet and outlet ports; Fig. 2, a section on the line 22 of Fig. 1; and Fig. 3, a detail of the dash-pot mechanism.
011 the drawings, 1 represents the valve casing and 2 the valve-seat which is preferably inclined as shown. The valve 3 is a swinging check-valve, keyed at its top to the rock-shaft 4, which extends out through the casing 1 where it is provided with the arm 5 having thereon the adjustable weight 6. The arm and weight are arranged so asto tend to close the valve 3 on its seat 2. The steam normally passes in the direction shown by the arrow 7 and thereby lifts the valve 3.
In case the pressure in .the boiler should for any reason become low, the valve 3 would normally tend to close of itself and would he assisted by the back pressure of the steam. To prevent the chattering of the valve 3 and to steady its action, the arm 5 is provided with the dash-pot 8, which consists of the stationary cylinder 9 and the piston 10, the latter being pivotally connected to the arm 5.
The valve-stem 11 has a pendent link 12 connected thereto by the pivot or pin 13. The remaining end of the link 12 is pivotally connected to the link 14 which is pivoted on the pin 15 supported in the casing 1,
, The back of the valve'3 is provided with the incline or fixed wedge 16, against which the lower end of the link 12 rides when the stem 11 is actuated to close the valve 3. The stem 11 may be moved upwardly so that the links will be out of the way of the valve 3, thus permitting the valve to open freely. If it is desired to close the valve, the stem 11 is lowered, the links acting as a knuckle on the incline 16 to gradually force the valve to its seat.
I claim- I 1. In a non-return valve, a casing, a valveseat, a valve cooperating therewith, a stem, a link connected thereto, a second link having one end connected to the casing, the remaining ends of the links being connected so as to form a knuckle; and an incline between the valve and the knuckle, said knuckle acting in connection with the said inclineto close the valve on its seat or to hold the same thereon.
2. In a non-return valve, a valve-seat, a valve cooperating therewith and provided on its back with an incline, a stern, a link having oneend connected thereto,:a second link connected to a fixed point and to the remaining ends of the first link, said links cooperating with the incline to cause the valve to close, or to hold the same closed.
Signed at- Pittsburg, Pa, this 2nd day of June, 1909.
