3 Claims. (Cl. 222-76) The present invention relates to a remote control liquid fuel dispensing attachment for a tank truck or tank trailer.

An object of the present invention is to provide a remote control liquid dispensing attachment which lends itself to safe and etficient transfer of liquid fuel from a tank truck or a tank trailer to a farm implement, one which saves fuel, time, and labor in such transfer of liquid fuel, one which is readily applicable to the trans fer of other liquids, such as liquid fertilizer, one which is sturdy in construction and of simple structure, easily manufactured and assembled, and one which is highly efficient in action.

These and other objects and advantages of the present invention will be fully apparent from the following de scription when taken in connection with the annexed drawings, in which:

Figure 1 is a perspective view of the upper end portion of the tank showing the remote control liquid dispensing attachment of the present invention installed thereon;

Figure 2 is a fragmentary sectional view of the dispensing handle of the present invention with a schematic view of the electrical components of the invention; a Figure 3 is a side elevational view of the dispensing handle and nozzle and a side elevational view of the electrical components as mounted within the box on the upper end of the tank; and

Figure 4 is a sectional view taken on the line 44 of Figure 3, and on an enlarged scale.

Referring in greater detail to the drawings in which like numerals indicate like parts throughout the several views, the remote control liquid dispensing attachment of the present invention comprises a base of inverted U- shaped configuration fixedly secured on the upper end of a tank 11 and an upstanding box 12 including spaced end walls 13 and 14 positioned upon and fixedly carried by the base 10.

A motor 15 having a drive shaft 16 is arranged within the box 12 so that the drive shaft 16 projects through the end wall 13 of the box 12. A starter assembly, indicated generally by the reference numeral 17, is positioned within the box 12 and is electrically connected to the motor 15 by a conduit 18 and grounded through. the base 10 and the framework of the box 12.

A switch 19 is positioned within the box 12 adjacent to and above the starter assembly 17 and is connected by wires 21 and 22 to thestarter assembly 17 for operation of the latter. The switch 19 includes a pair of fixed contacts 23 and 24 and a member 25 having other fixed contacts 26 and 27 projecting from one face and an element 28 projecting from its other face-is positioned so that the fixed contacts 26 and 27 are adjacent to a'ndnormally'out of contact engagement with the fixed' contacts 23 and 24 and the element 28 is remote from the fixed contacts 23 and 24.

The member 25 is mounted in the interior of the box 12 for movement toward and away from the fixed contacts 23 and 24.

An arm 29 is positioned within the box 12 adjacent the end wall 14 and is mounted upon the side wallof the box 12, there being a pivot pin 31 extending through one end of the arm 29 and anchored in the wall of the box 12 so that the arm 29 has rocking movement about the pivot pin as the horizontal axis. The arm 29 is contiguous to the element 28 on the member 25.

A pump 32 having an input side and an output side is positioned upon and carried by thebase 10 adjacent the other end of the latter and is operatively connected to the projecting motor shaft 16 by means of a short shaft 33 and a universal joint connection 34, the latter being of conventional make. a

A conduit 35 is connected to the input side of the pump 32 and extends to the tank 11 below the level of fuel contained therein.

A hollow elongated handle 36 is positioned remotely from the tank 11 and is connected to the output side of the pump 32 by means of a flexible conduit 37. A discharge nozzle 38 extends from the end of the handle 36 opposite to the point of connection of the conduit 37 and is connected in communication with the interior of the handle 36.

Within the handle 36 and adjacent the discharge nozzle 38 is positioned a valve 39 and a spring 41 keeps the valve 39 in the position normally preventing the flow of fuel from the handle 36 to the nozzle 38.

Hand actuable means is provided exteriorly of and carried by the handle 36 and is operably connected to the valve 39 for moving it from the flow preventing position to a position permitting the flow of fuel from the handle 36 into and through the nozzle 38.

Specifically, this hand actuable means consists in a lever 42 fixedly secured inwardly of one end to the stem of the valve 39 and slidable within the frame 43 of the handle 36 from the position in which the end remote from the valve stem, indicated by the reference numeral 44, is positioned within a notch 45 formed in the adjacent end of the frame 43, as shown in Figure 3, to a position in which that end of the lever 42 is toward the body of the handle 43 and remote from the notch 45, as shown in Figure 2.

Means is provided connecting the other end of the arm 29 to the lever 42 for movement of the arm 29 so that the fixed contacts 26 and 27 on the element 28 engage with the fixed contacts 23 and 24 to complete the circuit from a battery 46 to energize the starter assembly 17 and the pump 32 in'response to execution of the movement of the lever 42 from the flow preventing position to the flow permitting position. Specifically, this means includes a flexible cable element 47 enclosed in a sheath 48 and having one end fixed to the end of the arm 29 remote from the pivot pin 31 and havingthe other end fixed to one end ofa push rod 49, the other end beingpivotally connected to the adjacent end of thevlever 42. .A spring 51 biases the arm 29 for movementrto the position in which the fixedcontacts 26 and 27. on the element 28 are out of engagement with thefixed' contacts Band 24. The spring 51 haslone end anchored in the. box end wall 14 and the other end. secured. tothe. arm 29 intermediate the ends of the latter. y

In operation, the remote control dispensing attachment of the present inventionis installed uponatankpref erably mounted. upon a body or trailer body and transportable. to thework location, the; truck badger-trailer body'being provided with the battery 46 conventionally installed and having one side grounded to the truck or trailer body. The dispensing attachment is useful for refueling farm tractors, combines, and all implements which are self-powered. It may also be used to refuel power boats or any engine wherever located. The dispensing attachment provides a safe and efficient method of refueling any engine. The simultaneous actuation of the pump 32 upon movement of the lever 42, caused by'the movement fo the cable 47 to close the'contacts in'the switch 19permits the safe and accurate'di'spensing of liquid fuels without spillage 'or'waste. 1
