In order to provide for cushioning the downward movement of the pump rod at the end of its stroke and to provide means acting to start the rod hack again, I have provided a spring 26 which, as illustrated, is flat and is disposed in the path of movement of the teeth 1G on pump rod l5 and is mounted at the lower. end of the supporting frame l0. This spring, as shown in Fig- 'ure 9, is mounted upon a-yoke 27, the ends rod or will have a tendency to start the rod upward. This spring not only cushions and reacts against the pump rod but assists in securing a quick return after ythe down stroke of the pump rod. This quick return is secured through the use of the large segment gear 2O which engages with the pinion 23 and reverses the movement of the rack. One of the principal objects of this mechanism is that it lsaves power as well as increases vthe amount of water pumped, due to the construction of the mechanism and the quick return.

Iv claim 1. A pump rod lift comprising a supporting frame, a constantly operated driving shaft,` a counter shaft, a pump rod having rack teeth, intermeshing gear wheels mountedV upon the counter shaft and drive shaft,

`a segmental gear wheel on the counter shaft intermittently engaging the rack teeth, a pinion loosely mounted upon the driving shaft, a second pinion mounted on the driving shaft and meshing with the rack teeth on the pumprod and rotatable with the first named pinion independently of the driving shaft, and a segment gear mounted ,upon the counter shaft and engaging the first named pinion at a time kwhen the teeth of the first named segment gear are out of mesh with the teeth of the pump rod.

2. A pump rod lifting mechanism for mills comprising a supporting frame, a driving shaft mounted upon the supporting frame, a driven shaft mounted upon the supporting frame, a pump rod having rack teeth, a piu- .ion'mounted upon the driving shaft, a relatively large gear wheel mounted upon the driven yshaft andrmeshing with said pinion,

a segmental gear mounted upon the driven shaft and intermittently engrI ig the rack teeth, a pinion loosely mounted upon the driving shaft, a sleeve carried thereby, a second pinion mounted upon the sleeve and engaging the rack teeth of the pump rod, and a relatively large segmental gear mounted upon the driven shaft-t and engaging said second named pinion at times when the tiistnamed segmental ucar is out of engagement with the rack har.

3. A pump rod lifting mechanism for mills comprising a supporting frame, a driving shaft mounted upon the supporting frame, driven shaft mounted upon the supporting frame, a pump rod having rack teeth, a pinion mounted upon the driving shaft, a relatively large gear wheel mounted upon the driven shaft and meshing with said pinion, a segmental gear mounted upon the driven shaft and intermittently engaging the rack teeth, a pinion loosely mounted upon the driving shaft, a sleeve carried thereby, a second pinion mounted upon the sleeve and engaging the raek teeth of the pump rod, and a relatively large segmental gear mounted upon the driven shaft and engaging` said second named pinion at times when the first named segmental gear is out of engagement with the rack har, the last named segment gear being adjustable upon the shaft on which it is mounted.

4. In a pump rod lifting mechanism, a supporting frame, a vertically rcciproeatahlc pump. rod, the pump rod having rack teeth,

gear wheels having teeth engaging the pump rod, a driving flniftv means operated h v the driving shaft for rotating said gear wheels in opposite directions to cause the reciprocation of the pump rod, and means for enshioning the pump rod at the end ol' its downward stroke and causing a return impulse to he transmitted to the pump iod comprising a spring having its free end disposed in the path of movement; ot the lowest tooth oi the pump rod, and a spring supported vohe upon which the spring is mounted.

5. In a pump rod lifting mechanism, :i vertically reciprocatahle pump rod, a driving shaft, means operated by the driving shaft and causing the reciprocation of the pump rod, and means for cushioning the pump rod at the end of its downward slrolie and causing a return impuli-ry to he transmitted to the pump rod comprising a spring having its tree end disposed in the path 'of movement of a portion o f the pump rod, and a spring supported yoke upon which the spring isf-mounted.

In testimony whereof I hereunto alli.\4 my signature.
