POSITIVE-ACTION ROTARY-VALVE PUMP.

Application filed m 21., 1924. Serial 10.121335.

This invention relates to pumps and has for an object to provide a positive-action, deep well, rotary valve pump.

An additional object is to provide a low speed rotary pump designed to be bodily set in a deep well hole, and an object is to provide drive means whereby to eliminate friction of contact due to any weight of the pump shaft extension.

An object is to provide a rotary-valve, deep well pump of most simple form and compact parts most of which can be probeing to provide a pump of such design and 5 organization as to require but very little machine dressing or finishing.

Another object is to provide a pump of approximately cylindrical form so that it may be readily lowered in a naked orcasedgo well hole. In this connection an object is to provide for the mounting .of the pump as a unit and joint device between the usual suction pipe and the discharge tubing so that a pump of maximum size can be used within the hole. That is, to provide a pump of such design that its working elements are of a size nearly equalling, in overall dimension transversely, the diameter of the hole or casing.

manifest in the following specification of an embodiment of apparatus of the invention shown in the accompanying drawing; it being understood that other modifications,

\5 variations and adaptations may be resorted to within the scope of the invention and the spirit thereof as here claimed.

Fig. 4 is a section on line 44 of Fig. 1. Fig. 5 is an end elevation of a rotary valve.

Fig. 7 is an endview of a shaft coupling.

The present invention pertains to a type of pump embodying a disc-like rotor 2 the cylindrical periphery of which has a suitable number, four here, of radial teeth or blades 3 which, preferably, have thickened bases 4 to obtain strength. At each end of the rotor is a gear 5; these parts being fast More objects and advantages will be made on a stub shaft 6 having hearings in end hole. duced from round stock metal; an. object For economic construction, the meeting endfaces of the shell parts 7-8-11 are ground flat and smooth to meet tightly andare fastened 'by through bolts 12.

A set of twin discs 13 are disposed in peripheral contact with each other on the medial plane of the periphery of the rotor 2 and also tangentially in contact with said periphery. (Flgs. 1 and 2) these discs forming valves having shafts 14 in parallelism and being radial to the rotor shaft 6. The valve shafts have bushings 15 countersunk in seats therefor in the contiguous faces of shell parts 7-11, 811; these parts being pocketed or cut out to receive the interposed valves.

The rings 11 surround the gears 5 and these are in mesh with bevel pinions 16 fixed on the shafts 14 so that the valves and the rotor are turned in'unison and here timed two rotations of each valve to onejof the rotor. The rings 11 are shown as over lapping the margins of the end faces of the/- rotor and so form a closed annular fluid space in which sweep the teeth or hlades'3, which run close to the house 10.

,The rotor here has four blades 3 and to clear these -at regular intervals the valves 13 have marginal pockets 17, which obvious- 1y are cut or machined out to closely inter mesh, gear-fashion, with the rotor teeth.

Fluid flow into the shell is had through an mlet port 20 in the bottom 7 and its near ring 11, thence into the blade'chamber in house ring v1O; the inlet being disposed on the side'of the valves from which the blades run away, Fig. 3. Any blade running away from the valves causes a suction on its rear side and liquid is drawn into the space between the leaving blade and the valves. Liqiud trapped between the blades is carried around until it is brought adjacent to an outlet port 21 in head 8 and its near rin 11. Since the contacting valves 13-13 b o ck flow liquid is expelled at the outlet with positive force by blade 3 approaching the valves.

The pump has a discharge conduit 23 1n the present case forming a pump tub1ng leading from the well hole in which the pump is submerged. The tubmg includes a suitable number of sections coupled by collars 25 (one being shown). A collar is here threaded onto the threads 9 of the end block 8; this havinga gland 26 through which extends the stub shaft 6, this havlng a squared end 6.

A feature of my invention conslsts of means for driving the pump shaft 6 without throwing any weight of the driving -means on the running parts in the shell,

thus reducing friction thereof and avoiding rapid wear which necessitates pulling the pump from the well for renewals. The drive means includes a drive shaft consisting of sections 28 having squared (or other non-circular) ends to match the sockets in the ends of reversible couplings 29, only one of which is shown. The coupling has a cylindrical body rotatively fitted in a bearing 30 which is provided in each coliar 25.

Around the hearing are provided flow passageways 31 for liquid passing through the pump. Each socketed coupling 29 has a medial girdle 29 with faced ends to bear on the upper ends of their coupling bearing which thus form supports as well as bearings of rotation. The weight of each shaft section is taken wholly by its lower coupling and bearing.

The lowermost coupling (of a series) receives the stub shaft end 6.

Since each section of the extension shaft is supported on its own collar-bearing there is no tension created in the string and as each section is" detached or free from the next no binding tendency results from any disa-lignment of the shafting in a deephole.

The sections .of tubing 23 are joined by collars 25 in the lowermost of which the pump body is screwed, and on the lower end of the pump body is screwed the perforated suction pipe 33. The discharge tubing,

the pump body and the suction pipe are of substantially the same diameter and for a given well hole will be of a diameter just small enough to freely pass into and from the hole. The diameter of the pump is practically determined by the over-all diameter of the rotor with its blades plus thethin pactness and structural design. Usually pump tubing screws up right-hand and I show, by arrows, a right-hand rotation of pump shaft and rotor so that torque of action tends to tighten up the joint.

It is obvious that a machine of this type 1s workable as a motor when fluid is suppl1ed thereto under pressure as the driving medium.
