The result of this arrangement l is that while the diaphragm ot one of the ll lower chambers is moving outwardly to draw the fluid into that chamber, the corl is moving inwardly to en el the fluid from the upper chamber.

A worm wheel et@ is' arranged upon the sleeve 45 and is free to rotate thereupon. The crank disk 30 is peripherally formed into a worm 477, which meshes with the worm wheel 46.' A computing dial 48 is rigid with the sleeve 45 and is arranged upon the spindle el. The latter, projects through a central opening of the dial-and carries an indicating member or pointer 49. When the crank disk 30 is rotated it turns the computing dial 48 through the worm wheel a6, which, whilefree to move upon the sleeve 15, has a frictional engagement therewith which is suliicient to cause the sleeve to turn with It will be understood that the adjustment be regulated to correspond to the graduations of the computing mechanism. For instance, when l gallon of the fluid is pumped l gallon is registered by the computing mechanism. The arrangement is such that when one gallon of iluid has been forced through kthe casing, the dial has made avcomplete revolution.

Having. thus described our invention, we claim as new, and desire to secure by Letters Patent 1.
