JOHN H. MILLER AND JOHN H. OSWALT, OF CLAYTON, OHIO.

PUMP-MOTORy SPECIFICATION forming part of Letters Patent No. 482,800, dated September 20, 1892.

Apnlication filed April 8, 1892. Serial No. 428,406. (No model.)

To @ZZ whom it may concern;

Be it known that we, JOHN H. MILLER and JOHN I-I. OsWALT, citizens of the United States, residing at Clayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Pump-Motors, of which the following is a specification, reference being had therein to the accompanying drawings. v

This invention relates to improvements in pump-motors, and has for its object to regulate the motion obtained by a train of gears actuated by a descending weight, as shown in the accompanying drawings, in which similar letters indicate similar parts.

Figure l is a side elevation. Fig. 2 is a detached View of the speed-regulating device, partly sectional. Fig. 3 is a detached view taken from the under side of the upper part of the speed-regulator. Fig. 4 is a detached detailed view of a part of the speed-regulator in section, showin g wheel G with its shaft and crank-disk I.

The letters A A' indicate the frame of the machine. I g

B is a drum secured to the shaft B', upon which is mounted the gear' wheel O, which meshes into the pinion D, mounted on shaft D. Upon this shaft is also secured the wheel E, which meshes into the Wheel E', mounted upon the same shaft as gear-wheel F. Gear-wheel F meshes into the wheel G on shaft H. This shaft carries a crank-disk I, provided with wrist-pin z', having mounted thereon an antifrictionroller i'. On Bis wound a rope J, the free end of which passes over a pulley K, attached to a suitable derrick L, and suspends the actuating-weight K'. A crank-handle M on -shaft D' enables the weight to be Wound up by turning the wheel E, together with its drum B. When the weight is released, the whole train of gearing is put in motion. The wrist-pin on the disk-crank I enters a slot f in the vertical piece N and causes it, together with the horizontal arm N', to vibrate on its pivot n when the machine is in motion. It will be observed that the upper portion O of the speed-regulator is hollow and has a slot on the under side O for the entrance of the top part of the piece N, and that a spiral spring P bears against each side of the end piece N, and thereby prevents the jerk, jar, or uneven motion which would otherwise occur when the crank-disk I passes over its centers. The piece N has also an independent vibrating motion on the pivot n, as indicated in dotted lines in Fig. 2. The horizontal bar N' is cut away at n and n' in order to give it aspring when vibrating. It is also provided with adjustable weights R at each end, which we have found to add to the efficiency of the whole arrangement.

A pump is shown in Fig. l of the drawings, in which the pump-rod S is pivoted to the vibrating bar N', and thereby a reciprocating motion is given to the rod while the weight K' descends.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is

l. In a pump-motor, the combination, with a train of gears, of a horizontal arm pivoted to the framework, a vertical slottedV piece pivoted to the said horizontal arm, and springs limiting the vibration of said Vertical slotted piece, as shown herein and described.

2. In a pump-motor, the horizontal arm N', pivoted to the frame of the machine, adjustable weightsR on said arm, the vertical slotted piece N, the upper piece O, provided with springs P, in combination with crank-disk I and a train of gears actuated by a rope R and weight K', as herein described, and for the purposes set forth.

In testimony whereof we affix our signatures in presence of two witnesses.

JOHN H. MILLER. JOHN H. OSVALT.
