' delphia,'in the county of Philadelphia and State, of Pennsylvania, have invented new and useful Improvements in Rotary Pumps, of which the following is a specification.-

. -This invention relates to rotary pumps,

with respect to discs are dis osed- 1n s dewise relation to A angles with respect to the ra ii of the discs adjust-able stator end.

and an object of the inventionis' to provide a rotary pump which will develop a relatively great amount of out-going force in proportion to the size of the pump and: the power employed for operating t. I

Another object of this invention is to rovide a rotary pump, which isadjustab e to permit varying of the capacity. of the pump,

when desired, permitting the'samepump to be utilized with a relativelylow capacity for one capacit outlet orce of the pump. D

' A still further object of the invention is urpose or c to rovide a rotary pump as specified, which p inc u-des a 'rotorcomposed of a plurality 0 discs laterally corrugated at acute angles the radii of the-discs,- which provide a p urality of. circumferentially ockets which radiating the pump create a suction and provides space for receiving the fluid being pumped.

A still further object of this invention is may be utilized as a turbine or blower, by

.reversing the direction of rotation of the rotor.

Other objects of the invention will ap ear in the following detail description, an in the accompanying drawings wherein Figure 1 is a side elevation of the improved pump. v

Figure 2 is a longitudinal section through the pump.

Figure 3 is a vertical cross section through the pump taken on the line 3-3 of Figure 1. Figure 4 is aside elevation of one of the rotor discs or plates.

Figure 5 is an edge elevation of one of the rotor discs or plates.

' Referring more (particularly to the drawump comprises ings, the im rove rotary e substantially a stator 1 w ich includes t tubular or cylindrical body 2, having the. 60

end lates 3 and 4 attached thereto in any fluid through the (pumpl The endplate or head 3 is recesse in its inner. surface to provide the spaces 7 and it has a relatively ong bearing 8 formed axiall outer end of .which a' suita 9 is-mounted. The shaft 10 of the rotor le stuffing box structure 11 is rotatably carried by the bear-v ing- S and it has a rectangularportion 12,

formed thereon .at one end of which a collar 13'is mounted, while a reduced threaded r- 7 tion 14 is'provided at the opposite en of rectangular portion. The rotor plates or thereon on the discs 15 are provided with axial rectangular I openings 16 which fit over the rectangular v ortion 12 and connect the discs to the shaft f 10 for rotation therewith. The discs 15 are corrugated or cupped laterally, as clearly shown in and the corrugations are dis ,osed at acute to rovide sufiicient incline to the pockets as Figures 2 and 5 of the drawings,

in icated at 17 which are formed by the various corrugations to insure the creatin of the necessary and proper suction throu the pump "The discs are disposed in si ewise relation,- one with respect to the other, as clearly shown in'Figure 2 of the drawings, thus providinga plurality of circumferentially spaced pockets or buckets, certain of which are substantiall circular shaped in cross section, the outer si es of the outer discs are substantially semi-circular in cross section. Y

In the drawings, four of the discs 15 are shown, but it is to be understood, that any number of the discs may be utilized, without departing from the spirit of this invention and depending upon the capacity of pump desired. To permit variation or adjustable end abutment 20 is positioned "adjustment of the capacity of the pump, an '10 within the stator 1 'and is carried by a.

relatively large threaded. stem 21 which threads through the end 4 and is adjustable to permit variation of'the capacity space between its 'nner surface, and the. inner surface of the head 3, for permitting variationof the number of discs 15 employed to.

"circulation of fluid through the and 4 of the drawings, it will be By particular references to spaces adjacent to the axis of the discs, be-

tween the various pockets of the rotor to allowcireulat-ion of the fluid therethrough.

A suitable air chamber 23 ofany approved construction may be carried by the stator 1 and a relief valve 24 is provided to permit the relieving of the interior of the pump of air, when starting it.

It is, of course, to be understood, that the invention may be constructed in various other manners and-the arts associated indifferent relations, and therefore, I do not desire to be limited in any manner except as set forth in the claims-hereunto appended.

What I claim is:

1. In a rotary pump, a stator, a rigid abutment at one end of the stator, an adjustable abutment Within the stator, a rotor rotatable within the stator between said adjustable and rigid abutments, said abutments provided with arouate cu t-out portions gradually increasing in depth as they curve towards the outlet of the stato 2.'In a rotary pump, a stator, a rotor rotatably mounted therein, and composed of a plurality of transversely corrugated discs disposed in sidewisc engagement to provide a .lurality of circumferentially spaced poo ets, said corrugations tcrminatin at their inner ends outwardly of the axis of the disc to provide communicating spaces between the pockets, a rigid abutment at one end of the stator and adjustable abutmeutwithin the stator;

3. In a rotary pump, a stator, arigid abutment at one end of said stator, an ad justable abutment within the stator, said abutments provided with circuit cut-out portions, gradually increasing in depth as they curve toward the outlet of the stator, a rotor within the stator and composed of aplurality of transversely corrugated discs disposed in sidewise engagement one with the other to provide a plurality of circumferentially spaced pockets.

'4. Ina rotary pump, a stator, a rigid abutment at one end of said stator, an adjustable abutment within the stator, said abutments provided with ci cuit cut-out portions gradually increasing in depth as they curve toward the outlet of the stator, a rotor within the stator and composed of a plurality of transversely corrugated discs disposed in sidewise engagement one with the other, to provide a plurality of circumferentially spaced pockets, said corrugations terminating at their inner ends outwardly of the axis of the discs to provide communicating spaces between said pockets.

In testimony whereof I affix my signature.
