Application filed March 12, 1923. Serial No. 624,323. y

rlhis invention relates to pumps and more particularly to lift pumps, a type of pump having the pump operating mechanism located at a substantial dista-nce above the pump cylinder and piston.

It is an object of the present invention to provide pump driving ymechanism which preferably is power operated and in which the pump driving mechanism is entirely enclosed in a unitary structure which is adapted to be set over a Well casing and be connected With the pump rod. The structure ispreferably so arranged that the pump rod is not exposed after the structure has been Set in operativeV position.

A furthe-r object is to provide a pump driving'device which is substantially selilubricating from a common lubricant reservoir, thereby requiring lubricant to be supplied only occasionally at one place.` In this connect-ion it is a further object to provide means for preventing the escape ofV lubricant from the driving mechanism into the pump.

A further object of the invention is to provide for detachment of the pump driving mechanism from the pump rod and for removal ot' the pump driving mechanism from a position directlyoverthe pump Well casing by permitting sliding of the pump driving` iii-'.cha'nisin upoiiits support, thereby reducing the labor required tov disconnect the driving mechanism from the pump and to more the driving mechanism to a` location such as to permit access to the pump Well. A. further object is to provide in the unitary structure oi the pump driving mechanism v tor accessibility and easy removal of parts y,t'or adjustment or replacement. Y l

A further objoctof the invention is'to provide in a unitary structure a pump driving mechanism and an air compressor which may be, used for forcing air into a. storage tank into which Water or other liquid is lifted by Vj moans ot the pnmp.- In this connection it is an object oil the invention to provide for the lubrication of the compressor from the lubrivt-zii'i3'iesei.foir viithin the pump driving device.
