Abstract

Abstract This invention consists of an internally threaded vertically disposed hollow receptacle adapted to receive the lower end of a portable gasoline pump that may be of the manually operated type. The aforesaid receptacle has its lower end provided with a hollow rectangular member having an externally threaded shoulder located in the vertical center thereof. The just mentioned shoulder is provided with a nut that rests on top of the gasoline drum to which the pump is secured by means of this novel invention. Two diametrically opposed U-shaped members, which I personally call dogs, each has its vertical portion passing through the aforesaid shoulder. The upper end of each dog is in the form of a handle by which the dog can be rotated to lock the device in place on the gasoline drum since the lower end of each dog terminates in a horizontally disposed member adapted to fit under the inside of the drum when the dog is turned to a locked position, thus locking the gasoline pump to the drum.
