PUMP-MOTOR.

SPECIFICATION forming part of Letters Patent 10.702,52'1, dated .Iene 17, 1902,

Allllloationiiled September l0, 1901. Serial No. 74,883. (No models To If/ZZ whom t may concern,.- v f Be it known that 1, PHINEAsS. WOODS, a citizen ofthe United States, residing at Smithville, in the county of Clay and State'of Mis souri, have invented certain new and useful Improvements in Pump-Motors, of which the My invention'relatesto improvementsv in pump-motors; and my object is to provide a machine of this character which may be wound up at the convenience of the operator and used from time to time until it finally runs down,'when it may be rewound.

The invention consists in a hollow Weight adapted to encircle the water-elevating portion of the pump, shown Vin this instance in the form of an endless chain provided with cups, one or more cables for supporting the weight, means for taking up and paying out `the former and preventing the latter from contacting when ascending or descending with the pump, suitable gearing for transmitting motion from the weight to the pump, and means for arresting such motion when desired. By providing Va machine' of this character water may be hadat any hour of the day or night for stock and other purposes by the simple manipulation of a lever which will permit the weight to descend.

In order that the invention may be fully understood, reference isto be'had to the accompanying drawings, in which- Figure l represents a vertical longitudinal sectional view of the machine, taken on line I I of Fig. 2. Fig. 2 is a vertical cross-section of the same, taken ongline'II II ofFig. 1. Fig. 3 is a detail plan viewof the drum'and Weight forming part of the invention, with the connecting-cable in section to show the peculiar shape of the drum. Fig; f4 is a sectional view of the brake mechanism, taken on line IV IV of Fig. 2.' Fig. 5 represents a modified form of the drum.

Referring to the drawings by number, 1 indicates a horse-power mechanism/consisting of a supporting-frame 2, a bearing 3, in which is journaled a vertical shaft 4, carrying a rigidly-mounted bevel gear-wheel 5 at its lower central portion, and a sweepv 6, to which the horses are attached, at its upper end.

Meshing with the master-wheel 5 is a driven pinion bevel-gear 7, rigidly mounted upon theouter portion of a horizontal shaft 8, journaled in bearings 9 10, .secured to frame 2, anda frame 11, the'latter of which supports a platform 12 over the well or cistern 13.

j Rigidly mounted upon the inner terminal incloscs a train of gearing hereinafter de V scribed. Worm-wheel 15 is provided at one side with an integral clutch member 18, adapted to be engaged by a companion clutch member 19, slidably mounted upon shaft 16, but made to rotate therewith by a groove and feather 2021, respectively. Clutch member 19 carries a loosely-mounted collar 22, whichl is shifted back and forth with said clutch member by arms 23, having their opposite terminalsl pivotally connected to the collar and an operating-lever 24, fulcrumed at its lower end to a notched segment 25, secured outside of the casing upon the platform 12. Y

Rigidly mounted upon the centralportion of shaft 16 isa drum 26, having a V-shaped periphery 27, with outer (langes 28 to preventv the coils of a cable 29 from accidentally leaving the drum when rotating. The upper end of said cable is suitably attached to the small radius of the drum, and its lower end issecured to a transverse bar 30 in the upper por tion of a Weight 31', consisting of a cylindrical casing 32, open at its central portion and having an annular chamber 33 to receive sand or f posite end of the drumfrom the worm-wheel is a large cog-wheel 34, provided at one side with a spring-actuated pawl 35, adapted to engage a rigidly-mounted ratchet-wheel 36, which rotates the cog-wheel therewith when the weight is descending or slips by the pawl and allows thecog-wheel to remain stationary Loosely mounted upon'shaft 16 at the'op-V IOO.

when the cable is being wound upon the drum. Cog-wheel 34 meshes with and drives a pinion 37, rigidly mounted upon a horizontal shaft 38, journaled in the opposite sides of Also rigidly mounted upon said shaft is a large cog-wheel 39, which meshes with and drives a pinion 40, rigidly mounted upon a horizontal shaft 41, journaled in the opposite sides of the casing vertically above o shaft 38.

Centrally located on shaft 41 is a rigidlymounted sprocket-wheel 4.2,which operatively carries an endless chain 43, provided with cups 44, adapted to discharge their contents 5 into a spout 45, secured to the front of the casing.

The speed of shaft 41 is controlled by a mechanism consisting of a brake-wheel 46, rigidly mounted thereon and adapted to be o frictionally engaged by a peripheral brakeshoe 47, consisting of a metallic strap secured at its opposite terminals to an arm 48 and a lever 49, supported by a bracket 50, secured 4to one side of the casing. Lever 49 is ful- 5 crumed near its central portion to ears 51 and pivotally connected at its opposite terminal to a sleeve 52, reciprocally mounted upon a vertical shaft 53 of a governor 54 and adapted to be depressed by arms 55 upon the expano sion of balls 56 in the well-known manner.

o 57 58, respectively mounted upon the adjacent terminals of shafts 41 53.

1n Fig. 5 of the drawings, 1 represents a modified form of the drum, designed to dispense with the rod 33 and prevent the lateral 5 movement of weight 31 as cable 29 is wound or unwound from the drum. Said modification consists of a pair of drums 26, rigidly mounted upon shaft 16, and upon which a pair of cables 29 are wound. These cables a are attached to the adjacent ends of the drums, so that in winding or unwinding their upper portions will move laterally in opposite directions, while their lower ends, which carry the weight, will only move vertically and to- 5 ward or away from the axis of the drums as viewed from above. Should one of the cables 292L stretch more than its companion, weight 3l will still be maintained in a vertical position by an equalizing-bar 59, provided with eyes 60 at its opposite ends to receive the lower terminals of the cables and pivotally secured at its central portion to a bail 61, swiveled on the transverse bar 30. By employing two cables they are less liable to twist and throw the bar 30 in contact with chain 43, ang consequently rod 33n may be dispensed w1Y 1.

The operation of the machine is substantially as follows: To raise the weight, power is applied to the sweep, which through the intervening gearing rotates the drum and winds the cable thereon until the weight is sufliciently elevated, when the power is detached. During this operation the teeth on the ratchetwheel pass by the pawl on cog-Wheel 34 without engaging therewith, and consequently said cog-wheel, together with the train of gearing which it drives, remains stationary. Then when it is desirable to elevate water clutch member 19 is withdrawn from its companion 18 by lever 24, which disconnects the wormwheel15 from shaft 16 and permits the weight to descend. While the downward travel of the weight may be so slow as to be hardly perceptible, the movement of the cups is sufficiently rapid to elevate a large quantity of water in a comparatively short time, owing to the intervening gearingbetween cog-wheel34 and shaft 41, and should a sufficiency be raised before the weight has reached the limit of its downward movement the latter may be stopped by throwing clutch member 19 into engagement with clutch member 18, which will lock wormwheel 15 on shaft 16 and prevent them from rotating, owing to the former meshing with worm 14. As the weight descends its backward movement, caused by the unwinding of cable 29, would finally bring its inner surface in conliict with the cables if its lateral movement were the same throughout; but owing to the V-shaped periphery of the drum this latter movement gradually diminishes as the cable unwinds, and the weight is finally brought to the position indicated by the dotted lines, Fig. 3.

From the above description it is apparent that I have produced a machine that is simple, durable, and thoroughly effective for the purpose intended.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A pump-motor, comprising a train of gearing, a hollow weight, a cable connection between the weight and gearing whereby the latter is actuated by the descent of the weight, and means encircled by the weight for preventing the latter when moving from contacting with that portion of the pump which it surrounds, substantially as described.

2. A pump-motor, comprising a train of gearing, a hollow weight, a cable connection between the weight and the gearing, ahorsepower mechanism for winding the cable on the drum of the gearing, a governor for regulating the speed of the descending weight,and a guide extending through the hollow weight to prevent it from contacting with that portion of the pump which it surrounds, substantially as described.
