Reissued Sept. 3, 1935 UNITED STATES PATENT OFFICE VALVE OPERATING MECHANISM FOR TANK YEHICLES James A. Jensen, Philadelphia, Pa., assignor to Quaker City Iron Works, Philadelphia, Pa a corporation of Pennsylvania 30 Claims.

This invention relates to valve operating mechanism for tank vehicles such as are ordinarily employed in thedelivery of gasoline, oils and other liquid commodities. More specifically, my invention has reference to valve operating mechanism for liquid product delivery vehicles wherein the tanks are subdivided into a number of compartments having individual valves to govern outlets in communication with a common drain pipe that extends rearward along the bottom of the tank. and moreover wherein there is a utility or can box at the rear of the vehicle.

Considered from the broadest aspect, my invention is directed toward the provision of simple and reliable mechanism with segregated controls at a point on the vehicle convenient of access to the driverpreferably in the utility box aforementioned-whereby the drain valves may be operated either individually or collectively as required incident to dispensing the liquid contents of the Several compartments of the tank.

A further object of my invention is to provide in connection with tank valve operating mechanism characterized as above, auxiliary control 29 means, whereby, in theevent of fire at the delivery end of the drain pipe, the individual controls of any valves which may be open at the time, may be simultaneously actuated from a remote point on the vehicle, for example, at the front of the 3B latter.

Another aim of my invention is to provide in association with the auxiliary control means above referred to, means capable, in the event of a fire originating at the rear of the vehicle and persisting in the absence of the driver, of automatically actuating the segregated controls in the utility box, to eflect closure of any open drain valves.

Still another object of my invention is toinsure against the drain valves lieingleft open as a consequence of carelessness or forgetfulness on the part of the driver after making a delivery, through provision of means which will function automatically incident to shutting the door of the utility box, to trip the segregated controls of any open valves.

Other objects and attendant advantages of this invention will be manifest from the detailed descrlption following of the attached drawings, wherein Fig. I is a partial side elevation of a tank vehicle embodying my improved valve operating mechanism.

The vehicle tank chosen for the purposes of illustration herein, and comprehensively designated by the numberal IS in the drawings, is composed of four serially-arranged separatelyconstructed unit compartments ii of different capacities which are bound to each other and to the chassis ll of the vehicle, after common practice in this art, by embracing straps l8. Similar- 1y secured to the endmost tank compartment Ii at the rear of the vehicle I1, is a utility box I 9 for the storage of utensils, tools, etc. used in dispensing the liquids carried by the vehicle, said box having a door 29 hinged at 2| to swing upward to open position as shown in Fig. III. The several tank compartments l6 are individually provided with bottom discharge outlets 22 which connect with a common drain pipe 23 extending longitudinally rearward of the bottom of the vehicle. see Fig. I. Discharge through the outlets 22 is governable by individual valves 24 which may be of any approved design and which open upward against the pressure of springs concealed within them.

The mechanism which I have devised for selectively operating the drain valves 24 of a vehicle tank structure such as above briefly described. includes a group of segregated controls having the form of lever handles 25 which correspond in number to the valves, and which are housed within the utility box IE at the rear end of the vehicle. As shown in Figs. III, VI and VII, the control handles 25 are of angular configuration viewed from the side, and fulcrumed for independent swinging movement on a shaft 215 which is supported in a mounting 21 secured to the bottom of the box l9 by means of bolts 28, see also Figs. IV-VI. Pivotally connected at their lower ends to eccentric centers on the individual control handles 25 in the vicinity of the bends or angles of the latter, are kinked terminals or toggle links 29 (Figs. III, VI and VII) whereof the upper ends are in turn connected, with interposition of slack adjusting screw fittings 29a. to cables 30. The cables 39 pass through guide tubes 3i which extend upward in the compartment l9 and then longitudinally forward along the top of the tank l5 respectively to individual operating connections 32 for the valves 24 of the several tank compartments I6. From Figs. III and IV it will be noted that the guide tubes 3| are secured at their rear ends by a manifold clamp 33 supported on the top of an upright rectangular frame 34 surrounding the bracket 21, while their forward ends are individually secured as shown in Figs. I, II, IX and X to integral clamps 35 of the bearing brackets 36 of the operating connections 32, which latter are afllxed to the tops of the respective tank sections i6.

Referring to Figs. IX and X, each of the operating connections 32 comprises a bell crank member 31 which is fulcrumed at 38 on the bracket 36. In each instance, the forward end of the cable 38 is connected, by means of a clevis fitting 39, to the downward extremity 31a of the bell crank member 31; while the yoked horizontal extremity 31b of said member has its ends pivotally connected to the ends of a lifting fork 40 at the top end of a stem 4| which extends down through a stuffing box 42 on the bracket 36 into the tank compartment iii. A hooked link 43 extending up from the valve 24 in each tank compartment is connected, with interposition of a turn buckle 44 to the bottom end of the stem 4 I; and a helical spring 45 surrounding said stem and pressing downward against a collar 46 thereon, serves to maintain the corresponding cable 30 under tension, and, at the same time, assists the concealed spring of the valve 24 to hold the latter closed. Normally, the control handles 25 are maintained in vertical position as shown in Figs. IV and VII through engagement of toothlike lugs 25a on them with the top horizontal 21a of the mounting 21,

When any one of the control handles 25 is swung from the normal vertical position shown in Figs. I and V substantially through a quadrant to the horizontal position shown in Fig. VI, a pull is induced in the corresponding cable 39 with resultant opening, through the intermediate ele ments already described, of the drain valve 24 in the corresponding tank compartment l5. After being swung downward as just explained, the control handle 25 is prevented from returning by the toggle action of its eccentric center under the reverse pull of the spring 45 at the connection, with said eccentric center and the terminal or link 29 beyond the vertical through the axis of the rock shaft 26 forming the fulcrum center of said handle, whereby the valve 24 of the corresponding tank compartment is set or locked in open position to permit draining of such compartment. The downward swing of the control handle 25 is limited, as will be noted from Fig. VI, through engagement of said handle with the cross bar 41a of an element 41 which is illustrated in perspective in Fig. VIII, and, which, for reasons later on explained, serves as a trip member. As shown, this trip member 41 is formed at opposite ends of its cross bar 41a with drop hangers 41b which are apertured to engage the rock shaft 26 of the control handles 25 in the intervals between the bosses of the endmost of said handles and the sides 21b of the mounting 21, said hangers being secured to the rock shaft by pins 48, see Fig. V. Projecting laterally from the end hangers 41b of the trip member 41 are lugs 41c, 41d, which, by cooperation with the side verticals 21b of the mounting 21, permit a limited amount of rocking movement of the rock shaft 26.

To one end of the rock shaft 26 is pinned another lever handle 49, which is subject to the downward pull of a tension spring 50, and which is thus normally held in horizontal position as shown in Fig, III as a consequence of the enforced contact of the lugs 41c on the trip member 41 with the side verticals 21b of the mounting 21. By lifting the lever handle 49, anticlockwise movement will obviously be imparted to the rock shaft 26 and the trip member 41 attached to it, with attendant rearward displacement and tripping of any of the control handles 25 which may have been depressed, and of the terminals 29 by the cross bar 41a of said trip member, and with restoration of said handles to their normal upright positions by the cables 39 under the influence of the springs 45 of the connections 32. The drain valves 24 corresponding to the control handles 25 tripped as just explained are thus simultaneously released and permitted to close automatically under the action of their concealed springs.

In order to make it possible to close the drain valves 24 from the front of the vehicle in the event of a fire at the delivery end of the drain pipe 23, I have provided a supplemental control in the form of an additional cable 5| whereof the aft end is connected at 52 to the trip lever handle 49, and which is operable by means of a grasp 53 attached thereto at its forward end. As shown in Figs. I, II and III, the additional cable 5| is threaded through a guide tube 54 which extends upward in the compartment I 9 from a special clamp 55 on a bracket projection 56 of the frame 34, and then forwardly along the top of the tank H, with the guide tubes 3| for the cables 30, to fixed anchorages 51. Pulling of the grasp 53, will obviously result in lifting of the lever handle 49 in the compartment l9, and in turn, in the simultaneous closure of any valves 24 which may be open at the time.

For further protection against fire hazards, I provide a safety means capable of functioning automatically in the presence of heat or flame to cause closure of any drain valves 24 which may be open at the time. This safety means comprises a cylinder 58 (Figs. III, XI and XII) which is formed integrally with the clamp bracket 55 in the box [9. and which serves as a guide for a piston-like plunger 59. As shown in Fig. XI, this plunger 59 is cup-shaped in cross section and pierced centrally at 60 for free passage or reeving of the cable 5| therethrough during normal operation of the latter. A helical spring 6| with its lower end abutting an axially-operated disk 62 held by a pair of cross pins 63 in the bottom end of the cylinder 58, tends to urge the plunger 59 upward out of said cylinder. Fulcrumed at 64 to one side of the bracket 55 is an arm 65 which is normally held, by means of a fusible link 66, in the position illustrated in Fig. XI, with a lateral projection 61 thereof intercepting the plunger 59. Upon failure of the link 66 through fusion under the action of flame or heat, it is evident that, the armti will be left unrestrained whereby the plunger 59 is released tothe action of the Spring 6!. In being thus released, the plunger will spend its force upwardly against a clamp cellar 81m the cable 5], thereby causing the lever handle 59 to be lifted, and, in turn, causing any open drain valves 24 to be simultaneously closed through the inter vening parts of the trip means.

As a safeguard against lorgetfulness or negligence on the part of the driver to insure that the drain valves 24 are all closed before the vehicle gets under way after making a delivery,-I couple the lever handle 49, as shown in Fig. III, with a projecting anchorage B9 bolted to the door 20 of the compartment l9 adjacent the hinge 2%, by means of a link connection 10 consisting of a cable section H and a tension spring I2. As the projecting anchorage 69 moves upward in the box l9 to the dot and dash line position in Fig. III as the door 20 is shut, the trip lever handle H9 is automatically lifted and any open drain valve 24 closes as a result. The spring 12 constitutes a means to prevent breakage or bending of the interacting parts of the trip mechanism in case that the cable section (I of the connection I0 is too short.
