WILLARD R. WALKER, OF SYRACUSE, NEW YORK.
VALVE.
Specification of Letters Patent.
Patented May 20, 1919.
Application filed August 18, 1917. Serial N 0. 186,909.
To all whom it may concern:
Be it known that I, WILLARD R. WALKIER, a citizen of the, United States of America,
' and resident of Syracuse, in the county of Onondaga, in the State of New York, have invented n'ewand useful Improvements in Valves, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.
This invention relates to certain improvements in valves of the swinging type adapted to open in the direction of movement of the liqud through the valve case, to be used mpre particularly in the waste pipes or drainage outlets of dish-washers and analogous machines.
The primary object is to provide simple means for automatically closing and opening the valve when swung by its operating means to correspondin sides of a medial plane of movement so t at-the valve will be yieldingly held in both its open and closed posltions.
Another object is to utilize the valve seat and portion of the case to cooperate with the valve for limiting its movement in reverse directions, and to thereby avoid external limiting stops.
A further object is to pivot the valve to its swinging support so that it may automatically adjust itself to its seat when closed.
Other objects and uses relating to specific parts of the device will be brought out in the following description. I
In the drawings Fi re 1 is a top plan of a valve embodying t e features of my invention.
Fig. 2 is a lon 'tudinal sectional view taken on line 2-2, ig. 1.
Fig. 3 is a longitudinal sectional view through the center of the valve case and valve.
Fig. 4 is a transverse sectional view ofthe same device taken on line 44, Fig. 1.
This valve comprises a case -1-- having a straight lengthwise passage -2-. therethrough, and internally threaded portions 3-- at the ends of the passage for receiving pipe connections 4. and 4'con-.
stitutin a part of the waste pipe or drainage on et system of'the dish-washer or analogous' machine, the intermediate portion of the case being provided with a valve seat A disk valve is pivotally mounted on the free end of a rock arm 7 which is secured to a rock shaft 8 within the valve case 1 to swing the valve 6 to and from its seat -5 and allow the valve to, automatically adjust itself to said seat when closed, said valve being opened in the casing.
The shaft 8 is journaled in opposite walls of the casing in approximately the plane of the valve seat -5 and has one end extended through and some distance beyond the corresponding wall and provided with an external U-shaped crank-arm.-9- having a wrist pin .10 at one side of its axis anda hand crank 11- by which the shaft may be turned at will.
A tension spring 12- is attached at one end to the wrist pm -10. and has its other end attached to a projection -13 on the valve case 1 at the side of said axis opposite the wrist pin which, when the valve is fully open or fully closed, is disposed at one side of a direct line through the shaft axis and point oat connection of the spring with the case, so as to cause said spring to move across and to opposite sides of said axis for automatically closin and opening thevalve as the shaft is roc edin reverse directions by its hand crank 11.
The closing movement of the valve is, of course, limited by the valve seat 5 while the opening movement is limited by a portion of the case l in the path of the rock arm 7' or lugs 14 on the valve.
The hubv of the rock arm '.7 is secured to the shaft --8by means of a set screw 15- which, when the valve is closed, is registeredfwith an opening 16 in the vailve case to permit the insertion of a screw driver' 10 which the set screw may beloosened, an the shaft withdrawn endwise from y or replace the valve, the opening ,--l 6 bel ing normally closed by a plug 17.
The particular advantage of the-sprlng 12- and crank arm -9 connected as direction of'flow of. the liquid through the i described is to assure a positive closing or openmg of said valve by a slight'movement of the hand crank 11 and also to assure the. holdmg of the valve in either position of adjustment without special care .on the part of the operator, it being understood that the spring is of suficient tension to counteract any Water pressure Which may be exerted on the valve tending to open the same. .7
What I claim is: In combination withavalve case having a lengthwise passage therethrough and a valve seat intermediate the ends of the passage and at right angles to the axis thereof, a rockshaft journaled in the case in approximately the plane of the valve seat and at one side thereof a rock arm secured to the rock shaft Within the case, a valve mounted on the rock i arm and movable therewith to and from the valve seat a U-shape crank arm on the outer end of the rock shaft and a tension spring eX- tending 1n the same general direction as the passage and having one end attached to said crank-arm at one side of the axis of the rock-shaft and its other end attached to a portion of the case at a point beyond the valve seat so as to exert its tension in the direction of opening movement of the valve, the intermediate portion of said spring being movable across and to opposite sides of the axis of the shaft as the latter is moved in reverse directions to yieldingly hold the valve in both its closed position and in its open position.
In Witness whereof I have hereunto set my hand this 14th day of August, 1917.
WILLARD R. WALKER.
