A further object of the invention is to provide improved supporting and driving mea'ns for the pump shaft embodying ad-- justable features permittingtake-up due towear and permitting vertical adjustment of lo the pump shaft.

A further object is to provide an improved gear head of this character wherein the drive gearing is fully encased in a housing containing a lubricant,-with means 'for cooling the housing to insure long running of the g ;The tubular body portion 13 is closed at its lower end by a'bot'tom wall 19 with which.

Referring to the drawings in detail and '30 wherein similar reference characters designate corresponding parts throughout the several views, the improved gear head comprises a supporting base 5 embodying a base plate 6 from which extends a depending vertical 5 suction pipe 7. Communicating with the upper end of thesuction pipe 7 above the base plate 6 is an L-shaped discharge pipe 8 through which the water is delivered from the suction pipe 7. Supported horizontally 0 above the base plate 6 as by means of legs 9 is a top plate 10 of circular formation as clearly shown in Figure 4.v This preferably flat top plate 10 is supported coaxially above the suction pipe 7 and is provided with a plain, axially disposed circular opening 11.

Adjustably supported upon the top plate. 10 is a gear head proper comprising a gear casing 12 including a tubular body portion 13 being open at its upper side and. provided with upper and lower external annular advantages of the inven- 'Figure'2 is an enlarged vertical section 16 and bottom wall 19. 1 These cooling cham provides a chamber 25 flanges 14' and 15 respectively. Cast integral with the lowerend of the tubular body portion 13 is a tapered or hell portion 16 which terminates in a tubular supporting sleeve 17the lower end portion of which is threaded both internally and externally. The lower portion ofthis tubular supportmg sleeve 17 extends through the top-plate opening 11 and hasthreaded thereon a pump shaft adjusting nut 18 adapted to bear upon the upper side of the plate 10. As will readily be apparent, rotation 'of this adjusting nut 18 permits vertical movement of the gear fiasmg 12 'wlth respect to the siipporting ase ner wall 20 providing an annular cooling chamber 21- being cl0sed at its upper end and havlng communicating openings 22 at ing chamber 21' formed by the bell portion bers 21 and 21' are provided with suitable ports 23 for the circulation of water throu h the chambers.
