i VALVE-OPERATING-MECHANISM TANK.

Application filed September 19, 1923. Serial No. 663,654.,

To all whom it may concern:

Be it known that we, ANDREWTA. KRAMER and Anvarr M. GnIrriN, citizens of the United States, residing; at Kansas City, in the county oil Jackson and State of Mi souri, have invented certain new and useful Improvements injValve-Operating- Mechanism Tanks; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which. it appertains to make and use the same, reference being had to thjeaccompanying drawings, and to the figures of reference marked thereon, which form apart or this specification.

This invention relates to dispensing tanks and particularly to a coi'npartmental dis pensing tank forming part of a tank wagon construction. The. primary object of the invention is to provide means for shutting off the flow of fiammable'material such asoil in the case of lire. 2

The tanks of tank wagons are usually divided into compartments, each compart lnent containing a different grade or quality of oil and from each compartment there extends a pipe discharging at the rear end adjacent to the can box. I The ports in the.

compartments communicating with the pipes are normally closed by valves which may be unseated when the door of the can box is opened so that oil may flow. into the pipes. When the door of the can box is closed, the valves are permitted to seat. Our invention contemplates means for causing the valves to close in the case of fire when the door of the can box is open, whether by automatically or manually controlled means and the invention consists of certain novel parts and combinations of parts all of which will be specifically de-' scribed hereinafter, reference being had to the accompanying drawings, in which I Fig. 1 is a perspective view of a tank equipped with our invention, part of the tank wall being broken away.

Fig. 2 is a detailed perspective view of a release latch for manually releasing the valves to closing position.

Fig. 3 is a detailed perspective view of one of the valve stem cams.

Fig. 4 is a fragmentary perspective view of the tank showing the valve rod release.

Fig. 5 is a detailed perspective view of one of the valves.

Fig. 6 is a detailed perspective view of the release latch bolt. t

Fig. 7 is a fragmentary perspective view of tank showing a modified form of a valve bar release, and

F 1g. 8 is an end view of the tank with the modified form of release applied.

The tank 1 may be suitably supported upon a vehicle body and it may have at one end the usual cab 2, and the can box 3, the can box having a closure or door 4-. Each compartment is provided at its bottom with an opening, communicating with the pipe and in each opening is a valve cage (3 having a threaded portion 7 engaging the opening. The valve cage 6 is provided with a guiding column in which is a slidably secured valve stem 9 on the lower end of which is a valve 10 to cover and uncover the opening 11 through which the oil passes on its way to the pipes 5, it being understood of course that the pipes 5 have dispensing nozzles 12 of appropriate construction. The valve stem 9 extends through a gland 13 on the cam bracket 1%, the cam bracket carries a cam 15 on the edge of which a rocker arm 16 may move. The rocker arm or crank 16 is rigid with the valve stem 9 so that when the arm 16 rides on the high lobe of the cam the valve 10 will be unseated, but when it ispermitted to ride down on to the low lobe of the cam the valve 10Will be seated. The arn'is' 16 are all connected to a cam rod or bar 17 received betweenthe bifurcated portion 18 of a pivoted lever 19. Thepivoted lever 19 carries a pivoted arm 20, having an offset tooth 21 constituting a stop for the spring press bolt 22 slidable in the barrel 23 and adapted to engage the end 24 of the lever 19 so, that when the latch is in full line position (Fig. 2) thelever 1 9 and the arm will be rocked together to form a rigid connection between the rod 17 and the rod 25 connected to the elbow lever 26 pivoted at 27 to the tank and connected to the rigid arm 28 on door 4 by a fusible link connection 29. When the door 4 is opened the rod 25 will be moved longitudinally toward the rear end of the vehicle. The rod 17 will be moved in a forward direction through the

levers

19 and 20 which are now rigidly connected one to the other through the latch bolt 22. Therefore when the door el: is opened the arms 16 will ride up the cams to unseatthe valve 10 and permit oil to flow into the pipes so it can be drawn off through any of the dispensing nozzles 12. When the door is closed the reverse action takes place and the valves 10 will seat.

It fire occurs while the door a is opened and the valves are uuseated, the fusing ot' the link 29 will ordinarily break the connection between arm 28 and arm 26 so that the valve arms 16 can ride down the cams and close the valves 10 shutting oil the supply of oil from the pipes. Sometimes the link does not fuse, or fire may occur away from the link, or for some other reason the device does not automatically operate, then the connection be tween the levers 19 and will be broken by pulling the cord 30 on the end of the latch bolt 22, disengaging the

levers

19 and 20 and permitting the valves to close. The cord or cable 30 is accessible trom a point adjacent to the cab or at the front of the tank, this location being desirable because the latch bolt 22 will have to be manually actuated and of course it is desired to place the manual control as far away from the flame as practical.

In Fig. 7 we have shown a slightly modified form of connection between the door and the rod 25. In Figs. 7 and S the door 31 is a vertical swinging door as distinct trom a transversely swinging door and the door 81 carries an upstanding rod 32 having an arm 33 connected to a fusible link 34, similar to the link29. In other respects the construction will be substantially that of the preferred form. It will be apparent from the foregoing that means has been provided for controlling the supply lines from the several compartments of the tank in case of tire and that means may be either manually or automatically controlled so that in case of fire the closing of the valves to the supply pipe will be insured.

What we claim and desire to secure by Letters-Patent is 1. In combination with a tank having a discharge opening therein, a valve normally closing said opening and a can box on the tank having a door, of mechanism connecting the valve and the door whereby the opening movement of the door will unseat the valve. the mechanism having a fusible link as a part thereof.

2. In combination with a tank having a discharge opening therein, a valve normally closing said opening and a can box on the tank having a door, of mechanism connecting the valve and the door whereby the opening movement of the door will unseat the valve, the mechanism h'aving a fusible link as a part thereoi near one end of the tank and an independent manually operated valve releasing means at the other.

3. In a valve controlling mechanism ha ving compartmontal oil tanks, a plurality of vertical stems having valves on the lower ends for closing openings in the compartments by gravity, cams adjacent to the stems, lever arms on the stems to ride over the cams, a b'ar connecting said lever arms, a rod substantially parallel with the bar and a release lever normally connecting the rod and bar.

-1. In a valve controlling mechanism having compartmental oil tanks, a plurality of vertical stems having valves on the lower ends for closing openings in the compartments by gravity, cams adjacent to the stems, lever arms on the stems to ride over the cams, a bar connecting said lever arms, a rod substantially parallel with the bar and a release. lever normally connecting the rod and bar, said release lever consisting of two members and a release latch for normally holding the two members rigid.

In testimony whereof we afiix our signatures.
