SPECIFICATION formingpart of. Letters Patent No. 754,431, dated March 15, 1904.

' Application filed May 14, 1903. Serial No. 157,145. (No model.)

To all whom it may concern.- 1 Be it known that I, J AMES M. CROWLEY, a citizen of the United States, residing at Carl Junction, in thecounty of Jasper and State of Missouri, have invented a new and useful Pump, of which the following is a specification.

The invention relates to improvements in pumps.

The object of the present invention is to improve the construction of pumps and to pro vide a simple and comparatively inexpensive I balanced pump adapted with a short stroke to lift water acons'iderable distance, whereby it is adapted to be operated within a comparatively small space. 7

A further object of the invention is to provide a pump of this character in which it will be unnecessary to provide a column-pipe and -which will lift water on the downstroke of the lever for actuating the water-elevating mechanism. 7

With these and other objects in view the inyention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, itbeing understood that various changes in the form, proportion,

size, and minor details of construction within the scope of the claims maybe resorted to 'without departing from the spirit or sacrificing any of the advantages of the invention.

'In the drawings, Figure 1 is a vertical sectional View of a pump. constructed in accord Flg. 2 1s a horizon- Fig. 3 is a deintermediate of their ends by bolts 2 or other suitable fastening devices to a support 3, which may be constructed in any desired manner and Which is provided with opposite upright portions 4, having perforations 5 arranged at intervals and adapted to receive the pivots or fulcrums of the lazy-tongs, whereby the latter are adapted to'be adjusted to vary their length and to obtain the, desired length of stroke. The lazy-tongs are preferably formed of alternately-arranged single and double bars orlinks, the single bars or links being arranged between the members of the double bars or links; but any other desired arrangement may be employed for securing the necessary strength.

The upper ends of the lazy-tongs are pivoted to vertical bars or links 6, provided at intervals with perforations and adapted to afford an adjustable connection between a walking beam 'or lever 7 and the lazy-tongs. The walking beam or lever 7 is fulcrumed between its ends on the support 3, at the center of the top thereof, and is provided with an arm 8, which extends upward from the walking beam or lever 7,'as clearly shown in Fig. 1 of the drawings. The arm 8 is connected by a rod or bar 9 with suitable operating mechanism, (not shown,) and when the walking beam or lever 7 is oscillated the lazy-tongs will be'alternately expanded and contracted fora purpose hereinafter explained. The bars or links 6 permit the distance between the upper ends 4 of the lazy-tongs and the fulcrum point or pivot 2 to be varied, and one or more sets of links may be removed, or the number of bars or members of the lazy-tongs frame may be increased. The size of the support 3 and the length of the links or bars 6 may be varied, as will be readily understood.

The lower ends of the lazy-tongs are connected with elongated Valve stems or rods 10, which receive buckets l1 and valves 12. The valves, which preferably consist of cylindrical blocks, are secured to the lower portions of the rods by nuts 13 or other suitable means, and the buckets are capable of a limited movement on the valve rods or stems independent of the valves. The buckets, which are open at the top and bottom, are provided at their tops with spiders 14:, having central openings to. receive the valve rods or stems, and the lower ends of the buckets are closed on the upstroke by the valves, which are secured to the lower portions of the rods or stems.

Each bucket is provided at opposite sides with upper and lower antifriction rollers or wheels 15, arranged in pairs, as clearly shown in Fig. 1, and mounted between perforated lugs or cars, which project outward from the bucket at diametrically opposite points. The antifriction rollers or wheels are arranged in grooves 16 of vertical guides 17, which are provided at their upper ends with suitable seats 18, adapted to be engaged by the wheels of the bucket or receptacle for a purpose hereinafter explained. The vertical guide-bars, which are located at diametrically opposite points, extend downward from a trough 20 and project upward a short distance above the same. The trough is provided at opposite sides with openings 21 to receive the buckets and the valves, and it has upwardly-extending flanges surrounding the openings 21 to prevent any water from draining back into the well. The guide-bars 17 are located in recesses at opposite sides of the openings of the tank or trough, and the valves, which are preferably cylindrical, but which may be of any other desired configuration, entirely fill the openings when they are arranged as shown at the left-hand side of Fig. l of the drawings. On the upstroke the valve is carried upward against the lower end of the bucket or receptacle, thereby closing the same and confining the water within the bucket. The water is held in the bucket by the valve until the bucket arrives at the top of the guide-bars and engages the seats thereof. The bucket is thereby interlocked with the upper portions of the guide-bars, and when the lazy-tongs expand on the downstroke the bucket remains stationary until the lower end of the lazy-tongs engages it and forces it downward from the'seat. The valve-stem 10 is of sufficient length to permit the valve to move away from the bucket and permit the water to escape into the trough 20. In practice the upper portions of the guidebars will extend a suflicient distance above the trough 20, and the movement of the valve independent of the bucket will be ample to allow the contents of the bucket to discharge completely before the valve leaves the opening of the trough. The valve is increased in length, as illustratedin the accompanying drawings, in order to permit the necessary movement of the valve through the opening of the trough.

The valves are provided at opposite sides with vertical ribs or flanges'22, which slide in the grooves of the guide-bar l7, and the upper portions of the latter are sufliciently resilient to enable the buckets to be readily engaged with and disengaged from the seats 19; but any other suitable means may be employed for retarding the buckets at the upper ends of the guide-bars to secure the operation of the apparatus. This structure besides opening the buckets fordischarging their contents also insures the opening of the buckets on the downward movement of the lazy-tongs to facilitate filling the buckets.

Any suitable means may be connected with the bar 9 for operating the pump, and when the walking beam or lever is oscillated the lazy-tongs will be reversely operated. One of the lazy-tongs will be extended and the other contracted at each stroke of the walking beam or lever.

The trough 20 is provided with a spout 23; but any other suitable means may be employed for conveying the water from the buckets to the points desired.

What I claim is 1.
