13 Claims.
This invention relates to valves and particularly pertains to a selective valve manifold for use in connection with a plurality of tanks or with tanks having a plurality of separate compartments.
Tankv trucks for delivering gasoline or other 'oils are usually fitted with a plurality of tanks or with a single tank divided into separate compartments, each tank or compartment being fitted with a separate discharge valve. The outlets of these valves are connected to a meter through a common discharge pipe line. If a valve connected with an empty tank or compartment is deliberately or inadvertently left partly open, while delivering gasoline or oil to thedischarge line from a full compartment, air from the empty compartment is drawn into the discharge line and the meter will measure this air with the gasoline or oil and consequently the customer will exactly receive gallo'nage less than that indicated by the counting mechanism of the meter.
It is-the principal object of my present invention to prevent such an occurrence from happen- 25 ing, either inadvertently or deliberately, by providing an improved valve manifold capable of being connected with the compartments of a tank, which valve manifold includes selectively operable valves and a latching mechanism which t positively prevents opening of more than one valve at a time so as to prevent the simultaneous placing of two or more compartments in communication with the discharge line to the meter.
In actual practice I provide a manifold having a separate inlet connection for each compartment or tank, and a common outlet connection for connection with a meter. A separate valve is provided for each inlet connection, each of which valves is provided with a separate operat- 40 ing mechanism, the operating mechanisms being selectively operable. A latching mechanism is provided which is operatively associated With the operating mechanisms so that the latter are ,normally capable of selective operation'to open the selected valve. The latching mechanism is so constructed and so associated with the valve operating mechanisms that operation of one of the latter will actuate the latching mechanism to latch the remaining valve operating mecha- 50 nisms against valve opening operation.
One form which the invention may assume is exemplified in the following description and illustrated by way of example in the accompanying drawing, in which:
.lw Fig. 1 is a view in elevation of my improved invention with parts thereof in section to disclose certain features of construction.
Fig. 2 is a fragmentary view diagrammatically. arranged disclosing the relationship of the latch mechanism with the valve operating mecha- 5. nisms.
Fig. 3 is a sectional view through one of the valve units taken on line III-III of Fig. 1.
Fig. 4 is a similar view showing the valve in open position. 1
Referring more particularly to the accompanying drawing, Ill indicates a valve manifold having three separate inlet connections II which may be connected by pipe lines to three separate tanks or to three separate compartments of a 5 single tank. Although in the present instance I have shown the manifold as having three inlet connections, after an understanding of the invention, it will be apparent that it may contain two or more as desired. The Valve manifold has a single outlet connection and each inlet connection is fitted with individual valves which may be selectively operated to establish communication between any selected inlet connection and the outlet.
In the present instance the valve manifold is sectional as it is made of three valve bodies l4 enclosing three separate valve units, all of which are identical in construction. Referring to Figs.
3 and 4, it will be seen that each valve body [4 is formed with an intake chamber l5 communieating with an inlet port "5. The valve body is also formed with a discharge chamber l1 communicating with two axially aligned outlet ports H3. The axis of the inlet port I6 is disposed at 90 degrees to the axes of the outlet ports l8, and is disposed substantially midway therebetween. Each valve body M is provided with flanges circumscribing the outlet ports l8 so that a plurality of the valve bodies It may be arranged with their outlet ports in alignment and secured together to form the sectional manifold Ill.
The outlet port E8 of the valve body I 4 at one end of the manifold is connected with a discharge line l9 through the medium of a head member 20. The discharge line I9 is, as in usual practice, connected with the meter. I he outlet port [8 of the valve body I4 at the opposite end of the manifold is fitted with a head 2! which is plugged by a plug 22 so as to blank off this end of the manifold.
The intake chamber l5 of each valve body I4 is separated from the discharge chamber ll thereof by a partition 23 having a valve port 24 formed therethrough. This valve port is in axial ,55
alignment with the intake port It and is surrounded by a valve seat 25. A valve member 26 is disposed. in the intake chamber IE to co-' operate with the seat 25 in controlling the flow of fluid through the port 24. It will be noticed that the valve member 2% opens against the flow of fluid and closes with it.
The valve member 25 is secured on a valve stem 2'l which is guided for reciprocation in a valve stem guide 23 adjacent the inlet port It. valve member 25 itself is guided at its perimeter by radial guide ribs 23 formed in the body M within the intake chamber E5. The valve member 25, as described, is disposed and reciprocates coaxially of the valve port 2d and the inlet port It. It will be noticed that the valve stem 27 projects axially through the valve port 24 into the discharge chamber ll of the valve body l4 so that it may be manipulated to open the valve member 26. A valve spring 38 is provided between the valve stem guide 28 and the valve member and constantly tends to maintain the valve seated to close the valve port 2d;
Each valve unit of the manifold It is provided with a separate valve operating mechanism which consists of a valve operating shaft M which extends parallel to the axes of the outlet openings at a spaced distance therefrom, and is journaled in the walls of the discharge chamber as illustrated. Secured on this valve operating shaft 3| within the discharge chamber I? is a valve operating lever 32. It will be noticed from Figs. 3 and 4 that this valve operating lever 32 is secured at one end on the valve operating shaft 3!, while its free end isin a position when operated'to engage the adjacent end of the valve stem 21 so that movement in one direction of the free end of the valve operating lever 32 will move the valve stem 27 axially in a direction unseating the valve 2% and opening the valve port 24.
One end of the valve operating shaft 3i projects to a point exteriorly of the valve body it so that it may be fitted with a detachable valveopcrating handle (not shown) by means of which the valve' operating shaft 3i may be turned to actuate the valve operating lever 32 and move the valve member 26 to an open position.
The present invention is particularly concerned with means for enabling the opening of but one valve 26 at a time. This, as previously described, will prevent inadvertent or intentional establishment of communication between one tank or compartment with the discharge line l9 simultaneously, and thus prevent siphoning of air into the discharge line from an empty tank or compartment while gasoline or oil is being delivered from a second tank into the discharge line.
The means by which I accomplish this includes a latch finger 33 formed on each valve operating lever 32. Each latch finger 33 is formed with a cam end 3t. The latch fingers 33 are operatively associated with a sectional latching bar 35 which is so arranged and disposed within the manifold as to intersect the path of movementof the cam ends of the latch fingers 33, when the latter are moved as the operating levers are actuatedto open the valves 26.
X The latching bar 35 is composed of a plurality bf axially aligned but relatively movable latch bar sections which are separately journaled in spaced bearings 36 secured in the valve bodies id. The latch bar sections are capable of a limited amount of endwise reciprocation in the said bearings 36. A pair of these latch bar sections 36a and 361) are provided for each valve unit with their contiguous ends normally aligned with t the cam end of their associated latch finger 33.
These contiguous ends of the latch bar sections The head members Zll, and 2! at the opposite ends of the manifold are each formed with an outwardly extending bore 3 the axes of which are in alignment with the axis of the latch bar 35. A spring-pressed plunger 38 is reoiprocably mounted in each bore til. These plungers abut against the opposite ends of the latch bar 35 and tend to hold the same yieldingly in normal position as shown in Fig. l, in which position anyone of the valve operating mechanisms may be, operated to open its associated, valve member. 28. However, it should be pointed out that after one valve operating mechanism has been operated to open a valve, the latch mechanism is so actuated thereby that the remaining valve operating mechanisms of the other valve units are latched against valve opening operation.
From Figs. 1 and 2'it is obvious that by moving the cooperating latch bar sections of any one valve unit in opposite directions by the insertion of the adjacent latch finger therebetween, thatthe latch bar 35 will be lengthened. This lengthening will be permitted by yielding in an outward direction of the plungers 3%, but, however, this lengthening will be limited due both to the limited movement permitted the plungers 38 and the engagement of annular abutments 39 on the latch bar sections with the bearings 36.
that when the latch bar sections are shifted end,
Also, it is apparent J35 Wise during this lengthening movement created associated latch fingers 33, thus latching the latter against movement. This, of course, will prevent the other valve operating mechanisms from operation in opening their associated valve members 26.
It is manifest that when the latch finger 33 is k withdrawn from between the ends'of the latch bar sections, that the spring-pressed plungers will L return the latch bar sections to normal position so-that any other valve member may be selected for operation.
From Fig. 3 it will be apparent that the valve operating levers 32 must move a considerable';
distance before engaging the lower end of the-" valve stem 2'! for operating the same, and that] during this movement the cam end 34 of the associated latch finger 33 must pass between its cooperating latch bar sections, and if it is held from so passing, that the operating lever 32 cannot be brought into operative relation with the valve member 26.
This will prevent two or more" valves from being simultaneously and partially opened. valve, the latch bar must be actuated so as to valves.
In operation of the device, it is constructed In other words, in order to open one, prevent even partial opening of the remaining substantially as illustrated and described, and
when in normal position the latching mechanism and the valve operating mechanisms will be disposed substantially as shown in Figs. 1 and 3."
Any one of the three valve units may be then selected for opening to connect one of the compartments or tanks with the outlet connection l9. To do this the removable operating handle is applied to the proper valve shaft 3| and the latter is turned to swing the operating lever 32 in a direction to openthe valve 26. Immediately that this lever commences to swing, the camend 34 of the latch lever 33 projects betwee'n'the cam ends of the associated latch bar sections 3611 and 351), which will spread apart to permit the latch finger 33 to pass therebetween. In doing this, the cam ends of the other pairs of sections will be moved out of alignment with the latch fingers 33 of the remaining valve operating mechanisms so that any attempt to open the latter will be prevented by engagement of the latch fingers 33 with the latch bar sections. In the valve unit that has been selected for operation, the lever 32 will thereafter engage the end of the Valve stem 21 and unseat the valve 26. When the valve operating handle is moved to a position permitting the valve 26 to close, the latch bar 35 will return to its normal position as shown in Fig. 1 so that any other valve may be operated.
' From the foregoing it is obvious that I have provided an improved and simplified valve manifold which is so constructed that only one valve thereof may be opened at a time. It is also obvious that I have eliminated the necessity of providing any selecting mechanism which it is necessary to operate prior'to a valve opening operation. In my present apparatus it is only necessary to select and perform the opening operation of the desired valve and the latch mechanism operates automatically to latch the remain.-
