Applicationiled May S, 1916. Serial No. 95,026.
To all whom z't may concern.'
Be it known that I, WILHELM R. IJoHsE, a subject of the Emperor of Germany, but having filed my intention to become a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and Stateof Wisconsin, have invented certain new and useful Improvements in Butteriy- Valves; and I do'hereby declare that the following is a full, clear, and exact description thereof.
My invention refers to quick opening valves of the butterfly type, its primary object being to provide a simple, economical and eiiective control mechanism for the valve2 whereby it is firmly and positively held 1n its seated position and is capable of a full opening movement by a half turn of the valve stem.'
Another object of my invention is to provide the valve-actuating mechanism in such manner that When 4the valve is full open a straight passage through the valve shell is obtained without odering any material resistance to the flow of fluid therethrough.
Still another object of my invention is to provide means for locking the valve in any intermediate position from a point of leak to full open.
With the above and other minor objects in view the invention consists in certain peculiarities of construction and combination of parts as 'hereinafter set forth with reference to the accompanying illustrations..
and subsequently claimed.
In the drawings Figure 1 represents a sectional elevation of a valve embodying the features of my invention, the section being indicated by .line 1-1 of Fig. 2 with the valve/shown in its closed posltion; Fig. 2, a sectional view as indicated by line 2 2 of Fig. l, with the valve in its full open position, and Fig. 3, a detailed face view of a portion of the valve-locking mechanism.
Referring `by characters 'to the drawings, l represents a valve housing provided with an inlet port- 1 and a discharge port 1, each of the same being in alinement and the inlet port is provided with a straight valve seat 2. 'llhe valve housin isl also provided .with a cap closure 3 where y the'mecham'sm I housing ports and is stepped into a suitable -ment with the inlet opening is an eccentric 9, which eccentric is tted into a circular aperture l0 of an ear 11, the said ear being extended from a valve disk 12. lIhe ear is also provided with a circular slot 13 that communicates with the transverse circular aperture l0 therein, thesaid slot being extended through approximately 90. The eccentric is secured to the valve stem by a keypin 14, which pin is fitted into registered openings of the eccentric and stem. rIhe head 13 of the key-pin projects beyond the eccentric and extends into the slot 13, being adapted to limit movement or play of the eccentric within the valve ear. By this arrangement it will be seen that the eccentric is Vnot only held by the pin but serves as means for retaining the valve in its proper relation relative to the eccentric.
It will be observed that by the eccentric v connection between the valve and stem when the stem is turned in one direction the valve will be forced to its seat, as indicated in dotted lines Fig. 2, in which position the full throw of' the eccentric has 'not been completed. Hence a constant draw or pres sure upon the valve can be maintained even though slight wear will result through continuous usage, the normal limit, of movement ,of the outer-most portion of the eccentric 'lying in the dotted line X of Fig. 2 which passes through the axis of the valve stem. In this closed lposition the head 13 of the pin is at the opposite end of the slot to'that shown in Fig. 2. When it is desired to open the valve the handle is revolved in the direction as indicated by the arrow in Fig. 2 and upon the initial movement of the handle the eccentric will cause the valve to lift from its seat. After the handle has made a quarter of a turn the head of the key-pin will'have engaged the opposite end ofthe ear slot 13 and a further quarter movement of the stem in the same \direction will cause the valve to swing upon the axis of the stem to a full open position, as shown in Fig. 2. Hence it will be seen that the valve disk proper is approximately clear of the passage of water through the housing and the only obstruction ofi'ered to the straight flow is, the width of the ear.
ln actuating thevalve in either direction by manipulating the handle 8 it will be observed that the spring plug 7 w-ill not oer sufficient resistance to permit free movement of the stem and handle but when the handle is released the spring-pressed plug 7 will prevent displacement or movement of the stem, whereby the valve may be held in any position from a slight leak to full open. ln order to insure alinement of the disk with relationto the inlet opening, lprovide the housing with a spur 15 which is positioned near the, said inlet opening and isadapted to oppose the circular face of the valve when it isbrought intoapproximate alinement with the aforesaid inlet opening. Hence after it is partly seated by coming in contact with the spur further movement of Athe eccentricy in a closing position will be exerted to force the valve firmly to its seat.
l have shown the valve disk 12 adapted to receive a Jenkins disk 16 which is held inl position by a suitable screw-confined washer 17. By this simple method'the disk, when worn, can readily be replaced without incurring any expense except for the cost of the standard disk mentioned.
l am aware that valves of this type have I 'imams been devised, but the actuating mechanism,
so far as l am aware, of the prior art valves is such as to materially increase the cost of manufacture and, owing to the nicety of adjustments, the life of such valves in practice has been found to be short incomparison to their cost. With my valve structure the first cost of manufacture is reduced to a minimum as there is slight machine work to be done and the assemblage can be e'ected by unskilled labor. be considered in assemblage is the positioning of the valve with relation to the eccentric and stem and when these parts are properly positioned the headed key-pin is driven home, whereby all of the parts are confined.
l claim:
A valve of the butterfly type comprising a housing having a port valve seat, a rotatable stem extending across the seat, a valve disk for the seat,y an ear extending from the disk and provided with a circular aperture and a slot in connection with the aperture, an eccentrichead fitted on the valve stem and rotatably seated in the circular aperture, a locking pin extending through the eccentric head and stem, and said pin including a portion projecting into the slot ofthe ear for limiting movement of the valve disk with relation to the stem eccentric.
ln testimony that l claimthe foregoing l have hereunto set my hand, at Milwaukee,
in the county of Milwaukee and State of Wisconsin.
