WATER- ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 507,882, dated October 31, 1893.

Application filed March 8, 1893.

To all whom it may concern: I

Be it known that I, WILLIAM H. H. CAMP- BELL, a citizen of the United States, and a resident of Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Water-Elevators; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to improvements in that class of devices for raising water known as bucket wheel elevators, in which a series of tilting buckets are secured to chains or cables which pass over wheels located above the surface of the well or other source of sup ply, the arrangement being such that the buckets are filled as they successively dip into the Water and are discharged as they pass around the wheel.

The object of the present invention is to provide an improved elevator of the above character which shall possess superior advantages with respect to simplicity in construction and efficiency in operation.

The invention consists in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings: Figure 1 is an elevation of an elevator constructed in accordance with my invention. Fig. 2 is a central cross sectional view of the same. Fig. 3 is a perspective view of one of the buckets detached. Fig. 4 is an end view on an enlarged scale. Fig. 5 is a sectional view of the pivoted cable clamp, showing the manner of securing the ends of the cable thereto.

In the said drawings, the reference numeral vl designates a frame composed of a number of uprights and transverse beams, located in,

the mouth of the well or other source of water supply- Journaled in this frame is a shaft 2, provided with a driving pulley 3, which may be actuated by any suitable motor, and having near each end a pinion 4,which meshes with a cog wheel 5, secured near each end to ashaft 6, journaled in bearings 7, on the top Serial No, 465,118. (No model.)

cross beams of the frame. Cast integral with the spokes of this wheel is a sprocket rim or wheel 8, provided with a number of inwardly projecting sprockets 9, which drive the cables carrying the buckets. This sprocket wheel is also formed with an annular flange 10, which projects out beyond the ends of the sprockets and over which the cables pass.

The numeral 12, designates the buckets, which consist of heads 13, of wood or metal formed with two plain sides 14. and 15, at a right angle to each other and an intermediate circular portion 16, to which portions 15 and 16, is secured by nails or other fastening devices a sheet metal casing 17, leaving an opening 18, for the entry and discharge of the water. Each of these heads is provided with a pivot pin 19, which is eccentric to the axis thereof or at one side of the center, upon which is mounted a clamp 20, formed with a groove 21, on one edge, and on the outer face, at each end with a beveled stud or studs 23. The cables 24., which pass over the flanges 10, are seated in these grooves andsecured therein by means of rivets or other fastening de vices. For the purpose of securing the ends of the cable to the clamp, I form the latter, near each end with a hole or aperture 25, at a right angle to the groove. To connect said ends with the clamp, they are passed through said holes and turned back, forming a loop. A small wedge 26, is then inserted in the loop and the cable drawn back until it is firmly set on the. tapered hole. As an additional precaution against disengagement of said ends from the clamps, rivets, nails or other fastening devices 27 may be employed. Each of the heads is provided with a stud or stop 28, for limiting the movement of the bucket. The numeral 29 designates the penstock consisting of a rectangular box located between said wheels, aud at its lower end is provided with an outwardly extending spout fiume 30, which conveys the water under one of the main wheels. then extends upwardly to within a short distance of the top of the penstock and then outwardly to the point of delivery.

Centrally in each bucket is a partition plate 34, of the same shape as the heads and hav- This spout or fiume 5 ing a passage way at the lower end. The casing is also nailed to this portion which on its outer edge is provided with a catch 35, with which engages a hook 32, on the upper end of a vertical spring bar secured to one of the sides of the penstock.

In practice the cables and buckets are let down into the well, at the bottom of which may be placed guide wheels over which the cables pass, although this is not necessary. The wheels above the well being rotated, the sprockets on the sprocket rims will engage with the clamps on the buckets causing the cables to descend on one side and rise on the other, as is well known. When the buckets in rising reach the hooked bar 31, the hook therein will engage with the catch 32 of the casing tilting the bucket and emptying the water contained therein into the penstock. As the buckets pass beyond the flange 10, on the descent, owing to the eccentricity of their pivots they will turn partially back, as seen in Fig. 2, so that their heaviest side will be presented to the water, causing them to rapidly fill.

I have illustrated and described the wheels 5, as being cog wheels, but their peripheries may be plain so that they can be driven by a belt from a driving pulley.

Having thus described my invention,what I claim is 1. The combination with a water elevator bucket of the character described, provided with an eccentric pivot and a stop, of a clamp pivoted on said pivot having a groove in one edge, and a hole or opening near each end at right angles thereto, the cable seated in said groove having its end passing through said holes and the wedges inserted therein, substantially as specified.

2. The combination with the frame, the shaft journaled therein having wheels formed with sprocket rims and flanges, of the cables passing over said flanges, the buckets having eccentric pivots, the clamps carried thereby with which said sprockets engage, having grooves in which said cables are seated and secured, the stops for limiting the movement of the buckets and means for tilting the buckets, substantially as described.

In testimonythatl claim the foregoing as my ownI have hereunto affixed my signature in presence of two witnesses.

WILLIAM H. H. CAMPBELL.
