Description
8 Claims.
The invention relates to certain new and useful improvements in operating means for reciprocating valves, more particularly to such means as applied to quick opening self-closing valves which are frequently employedin locations where cent obstructions, such as pipes, beams, columns or the like.
The-invention is illustrated in the accompanying drawings, in which:-
Fig. l is a sectional elevation of a valve and the operating means therefor.
Fig. 2 is a fragmentary sectionalelevation showing alternative connections between bracket and valve stem.
Fig. 3 is an elevation of the bracket.
Fig. 4 is a. bottom plan view thereof.
the
Fig. 5 is a partial sectional elevation showing' a modified type of supporting bracket.
Fig. 6 is a similar view showing alternative applications of the lever.
Fig. 7 is an elevation of the base of the bracket.
Fig. 8 is a bottom plan view thereof.
Fig. 9 is an elevation of the link associated with the bracket.
Fig. 10 is a plan view of the operating handle or lever.
Referring to the drawings, l indicates the shell or casing of a quick opening self-closing valve of standard form', said casing being provided with a tubular neck 2, which is externally screw threaded and in which the stem -3 of the valve operates.
Surrounding the neck of the valve casing is the annular base 6 of a bracket 5, the body portion of which is substantially parallel with the valve stem and is provided at its end with ears 'i adapted to receive pivot pin 2i. The bracket is adjustable about the neck 2 of the valve casing and is clamped in any o-f its Various positions of rotary adjustment by the set nut 8 engaging the threads on the neck.
The outer end of the valve stem 3 has secured thereto a cap lil having spaced ears i2 adapted to receive pivot pin 22. The cap is provided with a socket ll somewhat larger in diameter than the end o1" the valve stem, which latter is preferably rounded` to 'form a rocking engagement with the bottom of thesocket, the stem being connected to the cap by means of pin I3, so that the cap is free to rock to a limited extent on the end of the valve stem.
The means for operating the valve consists of a lever i5, which is curved throughout its length and is provided at one end with longitudinally spaced eyes i6 and ll and having both of its edges between said eyes recessed or concaved as at i3 and i9 and also having its con cave edge adjacent the inner eye i6 recessed or concaved as at 26. This particular construction of the operating handle lor lever` l5 admits of the same being connected to the eared end` of the bracket and to the eared' cap yon the end of the valve stem in the Various positions indicated in Figs. l and 2. As shown in full lines in Fig. 1,` the handle acts as alever 4of the first class extending laterally and away from the valve casing at substantially right angles to the valve stem. As indicated in dotted lines, the handle has been reversed, but still operates as a lever of the lrst class with its body portion extending toward the valve casing in the general direction of the valve stem. In Fig. 2, the handle l5 is shown in its alternative connection with the bracket and the valve stem, namely, as a lever of the second class, the eye li being pivoted to the bracket 5 and the inner eye i6 pivoted to the cap i6. In the full line showing, the lever i5 extends laterally and toward the valve casing, and like the lever shown in full lines in Fig. 1 is disposed at substantially right angles to the valve stem. In the dotted position shown in Fig. 2, the lever has been reversed or turned over and extends laterally and away from the valve casing in the general direction of the valve stem. It is evident, therefore, that the handle is capable of application alternatively as a lever of the rst or second class and also reversely as a lever of either class, so that it is susceptible of being disposed in four angular positions relative to the longitudinal axis of the valve stem and, inasmuch as the bracket is capable of being rotatively adjusted about the neck of the Valve casing, the handle may be applied in any of its four angular adjustments relative to the Valve stem in any position of circular adjustmentsuabout the axis of the valve stem as a center. It is apparent, therefore, that the handle is capable of a very large number of adjustments, in order to 'enable it to pass adjacent obstructions, such as pipes, beams, columns or the like.
In the modication shown in Figs. 5 to 9. the
bracket comprises an lannular base portion 6' adapted to be clamped to the neck of the valve casing by set nut 8, and is provided with ears to which is pivoted eye 1 of a link 1', the outer end of which is finished with a clevis or double eye 1 carrying pivot pin 2|'. With this particular construction of the bracket, it is feasible to attach the cap l0 to the end of the valve stem by means of threaded socket Il' engaging threads on the end of the stem, so that the cap is rigidly secured to the stem, the'link 1' permitting the necessary swinging movement between the pivots 2| and 22' to prevent lateral strain on the valve stem, when the valve is operated in either direction. In all other respects, the construction and mode of operation is the same as those described in connection with the first modification, the handle or lever being adapted to be alternatively and reversely connected to the bracket and to the cap on the valve stem and also to be rotated to any desired position of adjustment about the longitudinal axis of the valve stem as a center.
As clearly shown in the drawings, the longitudinal curvature of the lever and the rotary adjustability of the lever about the axis of the valve stem admits of it being disposed in many positions of adjustment to clear adjacent obstructions and the provision of the concavities or recesses in the lateral edges of the lever adjacent the eyes enables this portion of the lever to clear adjacent portions of the cap and the bracket in all positions of adjustment of the lever.
