iiuid and expel it under pressure, or 'if the lluid is introduced under pressure acts to impart rotation to a suitable shaft and thereby transmit power. 1U
a gyratory pump for admittin and delivering a gaseous or liquid ilui under pressure. The invention, therefore, will be described as a pump, although it will be obvious to those skilled in the art that by the introduction of fluid under pressure 1into the chamber of the machine the impeller will be caused to gyrafte and thereby to act as a motor. y
One of the objects of the invention is to increase the efficiency of this type of machine by improvements in simplicity and compactness of construction and in vital details so that such advantages as direct Acon- ""5 nection to high speed motors with low surface speeds of wearing parts will be attained.
A further object of the invention is to 'provide a mechanism which requires no priming and which will be capable of act@ ing upon, or being acted upon, by'jliquids, steam or gas efciently and in a practical wav. The important object of the invention is to provide an adjustable spherical shell complementary to the spheroidal periphery of the impeller which may be either automatically or manually adjusted to maintain a close running fit upon the impeller and also 40 to'permit the impeller to grind its own perfectly fitting surface in the shell.
A further object of the invention consists in providing an improvedy partition crossing the chamber and intersecting the impeller with a sliding swivel joint .of such a i character as to prevent the escape of liquid from the compression side of the chamber tol the opposite side thereof.
A further feature of the invention consists 5,0 in providing an improved check valve for the ports leading to/or from the cha-mber of the machine.
' A further object'of the invention is to provide automatically adjustable glands to The invention more particularly relates to co-operate with the spherical hub of the im-v peller and also to provide means adapted to form an 011 seal for such glands.
A further' object ofthe invention is tcprovide a novel form of counterbalanced driving mechanism for the impeller shaft. A further feature of the invention consists 1n provldmg a construction in which the shaft of the impeller may be constructed in two sections adapted to be driven by a separate motor.
Various other objects land features of the invention will more fully appear from the following description and the .accompanying drawmgs and will be particularly pointed out 1n the claims.
-Preferred embodiments of the inventionv are illustrated herein as applied to pumps operable to pump a liquid or a gas or to act as a compressor.y It will be readily under- Stood that machines embodying' the invention may be made of any desired size, but that the primary object thereof is to provide a relatively small machine which may be actuated at a high speed and which may be used not only as a pump, but which may be readily installed as a compressor in small refrigeratin systems as those employed in domestic re rigerators.

comprise a base 1 having-suitable le s upon Vwhichis mounted a pair of ends'or t(heads 2 and 3 which are connected by suitable bolts 4 and clamp between them an annular member such as a shell 5, to form a chambered casing for the impeller. The impeller is in the form of a disk 6 having a spheroidal periphery 7 and provided with a spherical hub 8. The shell 5 is Provided with a spherical 'surface 9 Awhich is complementary lto the -spheroidal surface of the impeller disk and engages the same with a close running fit. An actuating shaft 10 extends from the hub 8 of the impeller perpendicular to thel me'- dian plane of the impeller disk and is actu` ated by suitable means which will hereinafter be more fully described.
The ends or heads 2 and 3 are provided respectively with faces 11 and 12 which are peller. 'The faces 13 and 14 of the disk are T illustrated herein as fiat while the complementary faces 11 and 12 of the heads are shown as slightly conical, but it will be understood that the disk may be provided with conical faces and the heads with flatI faces, as illustrated in Fig. 6, or that any other complementary arrangement of the faces may be employed within the scope of the invention.
The Working chamber in which the impeller gyrates is divided transversely by a' partition l5 which preferably is located in the lower portion of the chamber and intersects the impeller disk` and inlet and outlet ports 16 and 17 are located adjacent to and upon oppositesides of the partition 15. The inlet and outlet ports are respectively connected by manifolds 18 and 19 so ythat the fluid may be introduced through the inlet manifold to the inlet ports on both sides of the impeller and the outlet ports from each side of the impeller may likewise communicate with a common outlet conduit. Desirably these ports are vof cylindrical form-.a form most easily constructed-and are provided with check valves, a preferred form comprising a split spring cylinder 2 0 which is expanded into the cylindrical portion of the conduit to present a free edge 21 to the outlet port l17. The spring cylinder may be provided l with a lug or projection entering a recess in the wall. ofl the port to hold it in place.
Pressure of the Huid will force the free end portion of the spring valve inwardly, as
illustratedl in Fig. 9, permitting the uid to iow from the chamber so long as the fluid is under compression. As soon, however, as the 'compression is relieved the spring valve will expand and closethe port, as illustrated inFig. 8. f
By reason ofvthis construction a two-way pump is provided in which'the Huid is taken into the working chamber upon each side of the impeller and is expelled from the portions of the chamber upon each side of the v f y'impeller as the latter gyrates, thus producing a double-acting pump. It will, however, be understood that by providingseparate .ports leading to 'and from the chamber upon separate sides of the piston, the pump may be made single-acting where the iuid is supplied to th chamber upon one side of the impeller only, or the pump may be employedv to pump simultaneously diiferent flunds from the chambers upon opposite sides of the impeller. One ofthe principal features of the present invention is to provide means for preventing leakage between the spheroidal peripheral surfaces of the impeller and the wall of the chamber which` surround-s it. In
. the preferred embodiment of the invention illustrated herein an annular shell isv provided which has a spherical surface 9 com' and upon opposite sides of the vertical par-` tition 15. Desirably the shell is surrounded by a re-enforcing ringu22 which'isI provided with laterally extending', flanges 23 and, 24 which enter complementary grooves in the heads 2 and 3, the ring being clamped between the heads by the boltsfl. The shell 5- may be, and preferably is, slightly narrower in width than the space between the heads to permit it to spheroidal surface of the impeller and 'the complementary surface of the shell is vmost important in producing a construction havinga maximum eiciency. The usual method of employing packing rings as'parts of the cient, 4but may, :if desired, be supplemented j byradially disposed re-enforcing adjusting-- 'impeller offers serious objection as the fluid under pressure must not only. be prevent-n ed from leaking across the face of the impeller` but along the peripheral edges ofthe impeller formed bythe junction of the re-` `slip over the impeller yduring' the assembling of the machine. yThis resilience of the shell u may be employed to cause 'the impeller to grind itself and seat in the shell so that a close -running it throughout the' entirejl circumference of theimpeller will be ob' tained.
In `order to mamtaln such a close running Vfit means desirably areprovided for concentrically adjusting the shell. Various means may be used to accomplish this purpose. A preferred means illustrated in Fig. 3 cornprises a pair vof adjusting screws 25 and 26` which pass through the lower portion of the ring 22 and abut at their innerends against shoulders 27 and 28 formed in the shellin proximity to theends thereof. By setting up these screws the lower ends of the ring may be drawn together and the resilience of the shell will cause the shell to contract concentrically. This adjustment of the ring is usuallysufhscrews 29, asillustrated in Fig. 12, or such radially arranged adjusting screws located at suitable intervals along the periphery of the ring may be employed in themselves to provide such adjustment.
concentrically adjusted, as the prevention of leakage between the- The adjustment of the shellm'ay also be accomplished automatically by providing a servies of preferably pairs of helical springs 30 seated in suitable recesses extending into the ring 22 from the inner wall thereof, the springsBO engaging the outer face of the shell 5, as illustrated in Fig. 10. Another meansfor automatically adjustv .'ingthe shell is illustrated in Fig. 11 in Which-the outer surface of the shell is provided with a thickened portion 31 which fits in a complementary annular recess 32 eX- tending outwardly from the inner face'of the ring 22, the space between the thickened portion 31 and the bottom of the recess 32- providing a chamber intowhich fluid under pressure may be introduced from-aJ suitable source through' a pipe 33. Where means are provided for automatically adjusting the v shell the heads will not be clamped -upon the'edges of thexshell suflciently to prevent the shell from contracting, or at necessary intervals the nuts upon the bolts 4 may be slackened 'sufficiently to permit the automatic adjustment of the shell and thereafter tightened up. Where manual adjustment is provided the heads willfbe clamped tightly upon the shell and the nuts on the bolts 4 loosened at such times as adjustment is effected. Other means ,for manually' or automatically' adjusting the shell concentrically to maintain a close running fit upon the periphery of the impeller may be made within the scopev of the following claims.'
One of the prominent features of the invention consists in providing aconstruction which will prevent the passage of the fluid from the compressionfportions of the chamber past the partition which separates the compression side of the chamber from -the inlet side thereof. In the construction illustrated in Figs. 1 and 3 the re-enforcing ring 22 is illustrated as being an integral ring. In this construction the partition 15'is seatedv .in a: recess v3ft in the ring and its vertical edges are seated in corresponding recesses in the respective heads 2 and 3. The upper edgeof the partition is .spheroidally con- -cave to fitupon the. spherical surface of thev hub. The hub 8'is provided with a separately formed segment 35 which forms a continuation of the spherical/surface of the hub of the impeller disk las will be hereinafter more particularly described. This segl"ment is also engaged byv theupper edge of the partition 15.
' In orderto insure tlght joints around the partition, and particularly between the partition and the spherical hub of the impeller disk, and further to provide a guide for the reciprocatory movement of the impeller along the partition, hardened guiding and packing plates 36 and 37, which may be of any desired thickness, are placed along the opposite sides of the partition and at their edges set in suitable recesses in the heads 2 and 3. The lower edges of these guiding and packing pieces are made of spherical form and rest upon and it the inner periphery of the ring 5, while the upper edges are spherically concave to fit upon the periphery of the spherical hub 8'of the impeller and of the segment thereof as illustrated in Fig. 3. By reason of the fact that the lower edges of these vplates are engaged by the v shell, adjustment of the shell will automatias heretofore stated, comprises a continuation of the spherical surface of the hub. Cylindrical segments 38 and 39 areinserted in this bore upon-opposite sides of the partition and slidably engage respectively the guiding and packing members 36 and 37.
In order to permit full vibration `of the impeller disk transversely of the working chamber so as topreserve the continuous lines of contact between the disk and the respective heads, the edges of the cylindrical segments 38 and 39 may be slabbed off to present flat faces 40 which are flush with the walls of the impeller disk as illustrated in Fig. 4, or as an alternative construction the walls 2 and 3vof the head may be. bored to provide countersinks 41 into which the projecting edges of the segments 38 and 39 may enter when the impeller disk reaches the limit of its sliding movement along the partition 15 and lits guiding and packing members 36 and 37. By reason of these con- 1 structions the impeller disk is enabled to oscillate sufiiciently to maintain the continuity of the movement of its lines of contact with the respective heads of the working chamber and therebyreduces the clearance practically to zero-the term clearance being used in the sense employed in defining the space between the cylinder head and piston in a reciprocating piston engine. The travelling movement of the sliding and swivel joint isgraphically illustrated inthe development shown in Fig. 14.
This construction provides a tight swivel and sliding joint which will prevent the passage of luid from 'one side of the impeller to the other so that the two sections into which the working chamber is divided by the gyratory impellerdisk may be used independently and different fluids pumped or compressed in the respective sections of the ychamber' by merely modifying the form of inlet and outlet to receive and discharge struction is shown in which the re-enforcing e ring 22 is made in two parts which are connected together at the top and also at the bottom. The connection at the top is not shown, but the connection at the bottom is illustrated in detail in Fig. 13. In this construction the ends of 'the split re-enforcing ring 22 are countersunk to present flanges 42 and 43 which are clamped together by suitable screws or bolts 44. The partition 15 in this construction is clamped between the lower edges of the sections of the reenforcing ring 22. In this construction the same form of guiding and wear plates 36 and 37 and swivel and sliding joint connection to the impeller are provided.
` Another object of the invention is to provide a fluid-tight seal between the spherical hub of the impeller and the heads 2 and 3, the inner faces of which form the walls of the working chamber and thus prevent leakage of fluid from the working chamber. This is particularlyimportant where machines of this type are employed in household refrigerators in which it is undesirable that'the fumes shall escape from the working chamber.
In the preferred construction illustratedin Fig. 1 the heads are providedwith annular recesses 45 and 46 having enlarged countersunk portions provided with screw threaded walls 47 and 48 which receive sleeves 49 and 50, the inner cylindrical surfaces of which are accurately turned or ground. Therecesses 45 and 46 are of suiicient depth to receive a suitable soft packing which is engaged by the sleeves 49 and 50 thereby forming an adjustable stuffing box. Glands 51 and 52 are slidably mounted in these sleeves with a very close fit and are provided with spherical inner edges which engage the spherical surface of the hub 8 of the impeller. Suitable springs are provided to bear against the outer ends of these glands. As illustrated in Figs. 1 and 7 the springs are in the form of plates 5,3 0f spring steel slotted to provide inwardly extending tongues 54 which bear against the endsv of the glands 51 and 52. These annular spring plates are secured to the respective hubs by suitable machine screws. A suitable cap 55, which may be secured to the 4outer head 2 by the bolts 4,'encloses the end of the gland 51 and with it forms a chamber to receive a-lubricant which will maintain proper lubrication between the spherical hub of the impeller and the gland. In order t0 provide for the lubrication of the spheroidal peller.

periphery of the inil'eller disk a duct v56 may be provided in t le spherical hub communicating with this oil ychamber and suitable branches 57 may .be providedy to lead from the duct 56 to the peripheryofv the im- 6l which dips into a lubricant as'will here- -inafter more fully appear. The base of the van above the fiange 61 of the driving shaft with a port the wall of which is surrounded bv y the oil' is :project-ed from the flange 61 by conical portion is reduced in diameter to provide a cylindrical section 62 adapted to bel journalled in a suitable bearing 63 ina' casing 64: having at its opposite end an annulal,` ange 65`which is secured to the head 3 by the bolts 4. The conical section ofthe driving shaft is bored lengthwise at an anglel to its axis corresponding to the working( angle of the impeller to receive theactuating shaft 10 of the impeller. Av suitable bushing or bushings 67 'may-be provided for the l-impeller `shaft within this bore. The
nnpeller shaft has a screw threaded endof reduced diameter which is engagedbysuit-v able nuts 68 lwhich abut against thev base of a countersinlgor against thexbushing 67 a-nd'when adjusted hold the impeller and driving 'shaft in fixed' angular and `longltudinal relation. Such positive relation 'o ff the impeller and driving-shafts mayy also be maintained by the engagement of the shoulder of the driving shaft `at the base of the conical portion of the bea-ring 63;
By reason of the mountingof the impeller shaft in a bore in the conical portion o fthe driving shaft the weight of the driving shaft is counterbalanced by the mass of maf terial inthe conical portion diametrically opposite to the bore for the 'impeller shaft.
In order to;lubricate the bearings for the driving shaft and the impeller-actuating shaft the casing 64 is provided directly an annular recess 69 from which ducts lead to the respectiveibearings for the driving lshaitt. The cover (S9X for this porty d-esirablv presents a concave undenface' upon which centrifugal force and from which the oil 4flows into the annular recess 69 and thence through the ducts to the bearings of the driving shaft.
Any suitable means may be employed `for driving the shaft.` l Preferably an electric lmotor is to be used as the machinefisldesigned to be driven, ata high-speed. l
A modified yform of .the invention is' illus# trated in Fig. 2 which differs mainly from,
that above described in that the. reenf`orc ing ring is formed in sections whichl "are clamped together with the partition between the adjacent lower ends of the re-enforcin ring andinthat the glands for the hub o the' impeller are somewhatV differently formed and different means used to autolmatically holdthem in place, and in thata different vconnect-ion is provided between the n driving shaft and the impeller shaft.
In the construction illustrated in'Fi-g.n 2'
the glands 70 and 71 are duplicates vand are*A slidably mounted inl .sleeves 45 like those shown in Fig. 1. These glands are 'prof vided with concave spherical surfaces-which engage the spherical hub of the .impeller and are held in 'such enga ement by -rings'72 andy 73 having ends a uttin againstv therespective glands and `provi ed with outwa'rdly extending flanges 74 and"75 which are engaged respectively by series 76 and 77 of spiral springs.-v The series vof spiral springs 76 'are seated' in a suitable cav 78 .which is secured to the head 2 by the Eo able recesses'in a ring 79 which is engaged lts 4,'whi1e' .the .springs 77 are seated in suit-- by a1 liange 80 which'extends'` inwardly from a housing ,81 having an outwardly extending delige v82 which is ksecured to' the head `3 v'by-'ftlie'bolts'ai The construction illustrated in Fig. 2 is so designed that itpmay be caused to abut against or fit-upon the' cylindrical .end ofthe casing of a usual type of ,motor through which the driving shaft of the motor projects.V w
the construction 'illustrated in the accom- ,panying drawings the'k motor shaft "82 is Shown as projecting into the' end of the housing 81 while the bearing 83 for'thev motor -.shaftand which is a part Aof themotor casing-projects into a-recessj84in the end of.
the housing .-81. A suitablepacking 85 is clamped 1n a countersink-in 'the end ofthe Vna l housing by a plate'86 whichis secured to the end of the housing, thereby providing anoil-tight joint which will' prevent 'the 'escape of lubrlcant from the chamber of the' hous ing. The driving shaft is provided with an end portion 87 of reduced diameter whch ,ex-
tends into an aperture in a cross head 88 in: l I
one arm 89 of which the driving shaft 90 of the impeller is journalled. In Athis construc- 'tion the driving shaft is provided with a' flange 91 which abuts against one fend of the arm 89 of the cross head and a washer 92 and nut93, on the end of the driving Ashaft engaging the opposite end of thearm A89,'
serve to prevent longitudinal movement of the driving shaft in its bearing. The other arm of the cross head is provided with a counterweight 94 diarnetricallyl opposite to the bearing for the impeller shaft. This counterweight is of sufficient weight to bal-Y `causing positive rotation of the cross head.
The operations of the device as shown in Figs. 1 and 2 are identical: The rotation of the driving shaft imparts through the actuating shaft of the impeller a gyratory motion to the im leller disk. Diametrically opposite faces o the impeller disk engage the walls 11 and 12 respectively of the heads 2 and 3. The gyratovry motion of the disk causes lines of contact between the impeller vand the heads of the disk progressively to rotate. chamber between the heads of the machine and also intersects the impeller, Adivides the chamber into intake and compression por tions upon each side vof the impeller disk. When, during the gyration of the impeller, the line of contact between the impeller and the wall 11 of the casing, for example, passes the partition 15, its progressive movement forces the iiuid, which is ahead of the line of contact, toward and through the outlet port, whilethe constantly increasing space behind the line of contact produces a partial vvacl uum in that portion of the chamber and permits the vgradual introduction of fluid into the chamber behind the moving line of 'contact. When the line of contact of the impelleragain passes the artition 15 compressive pressure is exerted upon the fluid as aforesaid so that the operation of the device is continuous. The opposite side of the impeller disk operates inthe same manner, but
independently, the line of contact between the impeller disk and the wall of the face 12 of the head being always at one hundred eighty degrees to the line of contact between the impeller disk and the 'face 12. By
vreason of this balanced construction a practicallyv continuous delivery of fluid under pressure is maintained when the inlet ports are supplied from a common manifold and lihiedfluid delivered through a common mani- In the operation of the machine leakage past the partition 15 is prevented by the mechanismv above described and leakage from the chamber around the hub of the impeller is prevented by reason of the selfadjusting glands and the oil seal maintained thereby.
By reason of the adjustabi'lity of the shell The partition 15, which crosses the gyratory impeller in a separate piece which can be readily machined', in -that the heads, the glands, the sleeves, and other parts of the machine may be made of duplicate construction which greatly reduces the cost of manufacture.
The construction is suchy that if desired the impeller may be driven by two motors instead of one by merely supplying the hub of the impeller with a second driving shaft in axial alinement with that shown, driving such shaft from duplicate mechanism to that illustrated, and enclosing the shaft in a` suitable housing which may be a duplicate of the housing illustrated. Such a construction may be employedin respect to either v:of the devices shown in Figs. 1 and 2. An
illustrative example as applied to that shown in Fig. 2 is illustrated in Fig. 15 in which an additional driving shaft 99 is mounted in axial alinement with the shaft 90 and is connected to a cross head 10() which is rotated by the driving shaft 101 in the manner heretofore described. By reason of such construction any desired amount of power may be imposed upon the impeller. It also provides a further advantage of permitting the use of two relatively small motors lin place of a single large one of al capacity equal to the two.
