Application med July 5, 1912, serial No. 707,938.
T0 all rwhom t may concern Be it known that we, RALPH J. MEYER and IRWIN A. MOON, citizens of the United States of America, residing at Grand J unction,`in the county of Mesa and State of Colorado, have invented certain new and useful Improvements in Pumps.
Our invention has for its specific object improvements in rotary pumps.
In order to accomplish the object proposed, mechanism is employed consisting most essentially of a cylindrical Casin.'` and base-portion, furnished with inlet and outlet ports and provided with end-closures having shaft-bearings, extending transversely through their centers, whereinto a shaft is journaled. On such shaft vis fixed a cylindrical rotor, having a plurality of radial bucket-recesses, countersunk into the periphery thereof and disposed parallel to each otherI and to its axis. To the ends of the rotorcircular heads are secured concentric therewith and peripherally contacting the curved interior 'portions of the casing. In each recess in the rotor a bucket is housed, mounted on pivot-bearings in the heads, and adapted to swing outward into contact with the curved interior portions of the casing. The buckets are normally maintained in contact with the curved interior of such casing by means of springs. In the lower portion of the casing stationary camsurfaces are provided for retiring the buckets into their recessesin the rotor and for releasing them therefrom, at predetermined intervals. The cams are vertically adjustable, through a bolster located thereunder.
Referring now to the accompanying drawings, which form a part of this specification, Figure 1 is a transverse central vertical section of a pump vembodying our improvements. Fig. 2 is a section of the same, at the line 2-2 in Fig. 1. Fig. 3 is an isometrical detail of the rotor, the buckets and one of the heads thereof. Fig. 4 is a section, at the line 4 4 in Fig. 1, of parts there shown. Fig. 5 is a sectional detail showing means whereby the heads are secured to the rotor and the closures to the casing thereof.
Like reference characters indicate corresponding parts throughout the several views.
1 is a preferably integral cast casing, consisting of a segment of a cylinder 2 and base-portion 3 furnished with inlet and outlet ports 4 and 5 and provided with end- Specication of Letters Patent. I Patented June 6, 1916.
Renewed November 13, 1915. Serial No. 61,445.
closures 6 and 7 secured thereto and having shaft- bearings 8 and 9 extending transversely through the centers thereof. The bolster forms an abutment between the inlet and outlet sides of the pump.
10 is a shaft journaled in the bearings 8 and 9 in the closures 6 and 7.
11 1s a cylindrical rotor h'aving a plurality of radial bucket- recesses 12 and 13, countersunk through the periphery thereof parallel to e'ach other and to its shaft 10.
14 and 15 are circular heads, peripherally contacting the curved interior portion 2 of the casing 1 and securedconcentrically to the rotor 11, Fig. 5, by means of screws 16 extending through holes 17 inthe former into sockets 18 tapped into the latter.
19 and 2O are a plurality `of bucketspreferably approximately ,triangular in cross-section-having inlet ports 21 and outlet ports 22 connected by means of conduits nions thereon, in the bearings 25 in the rotor-heads 14 and 15.
26 are tension springs, connecting ears 27 and 28, on the rotor 11 and the buckets 19 and 20, respectively, and normally maintain the edges 29 of such buckets in contact with the curved interior of the cylindrical portion of the casing 1.
30 are cams-curved downwardly from and eccentrically to the axis of the rotor 11 to such an extent that the distance from such axis to the center points of the cams will equal the length of the radii of such rotorfor gradually retiring the buckets 19 and 20 into and releasing them fromtheir respective recesses in the rotor at predetermined intervals, and are located in the base-portion 3 of the casing 1. They are preferably secured thereinto by having their end-portions made fast in countersinks 31, Fig. 1, in the curved interior of the cylindrical portion 2 thereof.
32 is a bolster having notches 33 formed in the top thereof to admit the central portions of the cam 30, which are fastened thereinto by means of screws 34. The under side of the bolster is beveled from its center toward its ends, and it is rendered adjustable vertically, by means of wedges 35 inserted between the latter and the base of the cylinder.
36 are screws for maintaining the adjusted wedges in any desired position on the base of the mechanism.
The employment of the connected inlet t and outlet ports 21 and 22, in the buckets 19 and 20, insures instantaneous admission of water to .and itsl expulsion from the spaces, in the recesses- 12 and 13, back of the inner leaves a thereof, with the result that such buckets are thereby rendered very sensitive and responsive to the action of ltheir springs 26, and with the further result that the friction between the edges 29 of the outer leaves b and the interior of the cylindrical portion of the casing 1 and cams 30 is re-V duced to a minimum.
In the operation of the pump, practically the only wearing surface is at the tips of the outer leaves b of the buckets. These being swung outward by the springs 26 cause the buckets to take up wear automatically which is an important feature, since no water is lost by the wear. Furthermore, the contact of the outer blades of the buckets with the casing is always very slight because of the fact that each bucket is balanced. The two leaves of the bucket are substantially equal in area, and a close joint is made between the edge of the inner leaf a and the base of the recess in the rotor, so that the head pressure cannot enter the spaces l2 and 13 behind said inner leaves, and the pressure of the load on the inner leaf is the same as that on the outer leaf. Consequently there is never at any time any friction between the tips of the buckets and the casing except. that occasioned by the pull of the springs 26, no matter how strong the pressure worked against, and the entire weight of the load is borne at the close joint between the apex of the blades where the buckets are rounded to bearagainst the rotor. It is to benoted that there is no motion or change of position of the bucket while it is carrying the load, as the act of closing and opening one bucket takes place while theother one is carrying the load. Consequently the friction and wear on the buckets is reduced to a minimum, there being little or no pressure on them during the closing and opening part of the operation. The balanced bucket is important, because there is no more friction between the tips of the bucket and the casing under a heavy load than under a light load.
Assuming that power is applied to the shaft 10 wherethrough it is communicated to its rotor, which is being thereby driven in a direction indicated by the arrow, Fig. 1, and that water is entering the casing through its inlet port 4, the operation of the pump will be as follows: As the rotation continues,
insana the spring actuating the bucket 19 will cause its edges 29 to travel centrifugally outward, and as it traverses the contiguous portions of the cams 30, it will appropriate a part of the inflowing water and force the same upward and around through the space between the inner surface of thejcylindrical portion of the casing and the periphery of its rotor, and thence discharge it through the outlet port 5 of the pump-casing. Each revolution of the rotor will result in two rapidly successive operations: like the one just described..
Having fully described our invention, what we claim as new and desire to secure by Letters Patent is 1. In a rotary pump, in combination, a ro- 'tor having a plurality of bucket-recesses in the periphery thereof, heads closing the ends of the bucket-recesses, buckets having inner 2. In a rotary pump, in combination, a rotor having a plurality of bucket-recesses at the periphery thereof, buckets comprising inner and outer leaves of substantially equal area pivotally mounted in the recesses and having inlet and outlet ports in said leaves connected by conduits located between the leaves, wherethrough to admit water to and expel it from the bucket-recesses, and springs for tilting the outer leaves of the bucket outward, substantially as described and for the purpose specified.
3. In a rotary pump, in combination, a rotor having a bucket recess in the periphery thereof, and a bucket pivotally mounted in said recess, the bucket having inner and outer leaves on opposite sides of its pivotal axis, the inner leaf being movable toward and from the rear wall of the recess as the bucket oscillatesthe bucket also having passages extending through said leaves from the recess between the rear side of the inner leaf, and the rear wall of the recess to the rear side of the outer leaf.
In testimony whereof, we have hereunto set our hands this 18th day of March, 1912,
in the presence of two witnesses.
