WATER-MOTOR.

Speccaton of Letters Patent.

Patented Jan. 27, 1920.

Application led April 911, 1919. Serial No. 291,549.

To all whom it may concern:

Be it known that I, lvnnson' D. Humans, a citizen of the United States, residing at Kirkwood, in the county of Dekalb and State of Georgia, have invented certain new and useful Improvements in later-Motors, of which the following is a specification.

rlhis invention relates to improvements in hydraulic motors and has for its object to provide a motor in which power is obtained from the vertical oscillation of a pair of arm carried buckets which are alternately lled with and emptied of water deposited therein when the buckets assume an elevated position.

Another object is the provision of a motor of this character in which the pivoted buckets are locked in elevated position until a predetermined' quantity of water is deposited therein whereupon the weight of the liquid is utilized to release and permit the bucket to descend under the weight of the liquid contained therein.

Another objectvisthe provision of means facilitating the automatic release of the bucket upon the reception of varying predetermined quantities of liquid so as to vary the power developed by the motor and thereb v economize the consumption of water when the motor is carrying a relatively light load.

Vith these and other objects in view as will appear as the description proceeds the invention comprises the novel features of construction, combination of elements and arrangement of parts which will be more fully described in the following specifica.- tion and set forth with particularity in the claims appended hereto.

Figure 1 represents a side elevation of the improved motor,

Fig. 2 represents a vertical sectional view on the line 2-2 of 1, and,

Fig. 3 represents an enlarged detail sectional view through the tank, bucket and valve controlled thereby.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views the numeral 5 indicates a supporting base carrying an upright frame structure consisting of a series of vertically disposed beams 6 to which the cylinder supporting plates 7 are attached.

A series of horizontally disposed cylinders 8.' are; rigidly supportedf upon. the plates 7 and the cylinders are arranged in pairs, the cylinders of each pair being arranged in superposed relation and provided with reciprocable pistons 9 carrying rods 10. rl`he lower pistons of the opposed pairs are connected by the rods 10 and likewise the upper cylinders of the opposed pairs and the adj acent surfaces of the rods, which latter are preferably offset as illustrated in Fig. 1, are formed with gear teeth which mesh with pinions 11 carried by a power shaft 12 journaled in bearings 13 adequately supported upon the plates 7 and constituting spacing elements. The shaft 12 is rocked back and forth by the mechanism to be hereinafter described and imparts reciprocal movement to the rods 10 through the gears 11.

The frame structure 6 supports an elevated tank 14 preferably of cylindrical form and arranged horizontally. A main supply pipe 15 adjacent to which the motor is arranged is connected by a branch pipe 16 with the medial portion of the tank 14 and the end wall 17 of the latter is provided with tubular extensions 18 having iianged inner terminals 19 arranged internally of the tank 14 and constituting seats for valves 20. Each valve is pivotally supported at 21 internally of the tank 14 and is adapted to cooperate with the seat 19 to control the admission of water to the extensions 18. Each valve 1s connected with a jointed rod 22 which is eX- tended through the end wall 23 of the eX- tension and is connected with the lower terminal of a trip arm 24 pivotally secured to and depending from a supporting rod 25 rigidly supported upon the top of the tank 14.

The rock shaft 12 nonrotatably supports a sleeve 26 confined between the two intermediate brackets 13 and carrying integral radially projecting arms 27 which are preferably arranged at an angle of approximately 90O to each other and are provided terminally with forks 28.

Laterally projecting trunnions 29 carried by each bucket 30 are pivotally mounted .adjacent the terminals of the forks 28 and the trunnions are arranged out of line to the diametrical plane of the bucket so that the latter normally tilt inwardly, except that they are counterbalanced bv adjustable weights 31 carried on outwardly projecting arms 32 rigidly secured to the outside of the bucket. The top of each bucket sopen and,

when elevated, is disposed directly under the discharge end of the spout 33 communicating with each extension 18 whereby water is discharged into the bucket when the valve 20 is open. However, the valve is normally retained in closed position by the tension of a spring 34 confined between one of the supporting brackets for each extension 18 and the arm 24, the latter' being engageable by a rod 25 carried by the terminals of the forks 28 whereby the valve is automatically opened as the bucket and arm approach the limit of their upward movement.

When the bucket 30 is empty, the force exerted by the weight 31 is sufficient to counterbalance the bucket 30 and retain the latter in outwardly and downwardly inclined position so that the latch 36 carried by the inner portion is engaged behind a. keeper 37 carried by the terminal of the tank 14.

In this manner, as the bucket moves upwardly to a position underneath the spout 33, the latch 36 is engaged behind the keeper 37 and the bucket is thus held in elevated position until a suiiicient quantity of water has been deposited therein to overcome the weight 31 and tilt the latch 36 out of engagement with the keeper 37 thereby rcleasing the bucket and permitting the latter to move downwardly under the weight of the water contained therein.

The bottom of each bucket is provided with a discharge opening 38 over which is arranged a pivoted flap valve 39 normally retained in closed position by gravity and adapted to be automatically opened as the bucket approaches the limit of its downward movement by engagement with an upstanding lug 40 carried on a platform 41 upon which the bucket is supported when in its lowermost position.

In operation, the tank 14 is supplied with water by the supply pipe 16 and assuming thatvthe parts are in the position shown in Fig. 1, the rod 25 is engaged with the right hand arm 24, thereby retaining the valve 20 associated therewith in open position and i permitting the liquid contents of the tank 14 to discharge into the right hand bucket 30. As the weight of the contents of the bucket 30 reaches a predetermined value the weight 31 is counterbalanced and the latch 36 tilted out of engagement with the keeper 37 thereby releasing the bucket and permitting the latter to move downwardly under the weight of the water contained therein. As the right hand bucket and arm descend the rock shaft 12 is rotated in a clockwise direction moving the pistons 9 in the upper cylinders to the right and producing an opposed movement of the pistons in the lower cylinders and moving the left hand arm 27 and empty bucket carried thereby to an elevated position. As the 27 in the position shown in dotted lines inv Fig. 1 and the parts are retained in this position until the left hand bucket is filled and the weight of its contentsv counterbal ances the weightv 31 thereby releasing the latch and permitting the bucket to move downwardly, such movement edecting rotary movement of the rock shaft 12 in a counter-clockwise direction and effecting an opposite movement of the pistons 9. If preferred, the cylinders S may he provided with air inlet valves (not shown,) through which air is drawn during the suction strokes of the pistons 9 and during the subsequent compression strokes of the pistons the air is discharged through pipes 42.

l/Vhat I claim is:
