ROTARY POWER DEVICE.

Application filed March 10, 1,919. Serial No. 281,892.

To all 'whom t may concern:

Be it known that I, ELLICK H. GoLLiNes, a citizen ofthe United States, and a resident of the city of Chicago, county 0f Cook, and State of Illinois, have invented certain new and useful Improvements in Rotary Power Devices; and I do hereby declare that the following is a full, clear, and eXact description of the saine, reference being had to the accompanying drawings, `and to the numerals of reference markedthereon, which form a part of this specification.

My invention has reference more particu larly to a rotary power device comprising eccentrically arranged members having iiuid compartments therebetween, whereby fiuid is passed throughthe device by rotation of either member. y Y

It is an object of my invention to provide an improved rotary power device which may be used either as a pump or motor.

Another object of my invention is to providel a rotary power device comprising eccentrically arranged inner and outer members with achamber therebetween having swinging partitions, operating upon rotation of either member to afford correspond- K ing enlarging and diminishing compartments adaptedto effect a transfer of fluid through the device.

Anotherobject of my invention is to pro` vide a rotary power device vcomprising eccentrically arranged inner and outer mem bers with a chamber therebetweenhaving swinging partitions, operating upon rotation Y of one of the members to afford corresponding enlarging and diminishingI compart-4 ments to effect a transfer offiuid through f the device, the said partitions being adapted to interlock with one another as the de' vice is operated, to afford an effective sepa- 'ration between theenlarging and diminishing compartments. Y

A furtherobiect of my invention is to provide a rotary power device comprising eccentrically arranged rotary members either of which may be held stationary as the other is rotated to thereby effect a transfer of lfluid through the device, and in which each member rotates only in one direction which is opposite to the direction of rotation of the other member, and such rotation of either member effects a transfer of liuid in the same manner through the device. In other words, the device may be driven in Specification of Letters Patent.

Fig. 10 is a view, similar to Fig. 2, of a Fig. l1 is a' fragmentary viewy similar to Fig. 10,showing a different stage of the operation.

As shown on the drawings: Referring first to Figs. 1 to 9 inclusive, the reference numeral l indicates the base of the device upon which are mounted pairs The bearinfr support 3 is cut away at 6 for a purpose 2 hereinafter indicated and thus differs from its corresponding bearing support 2, but otherwise the kbearing supports of each pair are alike and serve the' same purpose. Each of these bearing supports taken through the axis- Y of bearing supports 2 3, L.1 -4c, and 5 5. i

is kcomposed of a pairV of half sections, as

shown in Figs. 8 and 9, with opposite semicircular half bearings, at their upper; ends, which are clamped around the portion of the device engaged therein, by means of bolts 2l and 22, which connect the half sections above and below the bearings.

Mounted between the

bearings

2 and 3, is a casing comprising a drum 7 which is closed at its ends by the

plates

8 and 9,v each of which is provided with an axial sleeve or hub extension 49, journaled in the

respective bearings

2 and 3 to support the casing for rotation.

Mounted within the casing 7-89 is a hollow cylinder 10, the end walls 11 of which are spaced apart so as to lit closely against the

end plates

8 and 9 of the casing and permit relative rotation thereof, and a tubular hub 12 is arranged eccentrically on each end wall 11 of the cylinder 10, and in alinement with one another, each of said hubs being journaled in the sleeve 49 of its

adjacent end plate

8 or 9, as shown in Fig. 7

Secured within each hub 12 or, if desired, made integral therewith, is a hollow shaft or pipe 13, which extends outwardly and is journaled in the bearing 4 and extends into the bearing 5. Each bearing 5 has mounted therein the enlarged end 14 of a pipe which communicates with the hollow shaft 13, and has the end of the latter journaled therein as shown in Fig. 7, one of these pipes, which serves as the inlet when the device is used as a pump and as the outlet when used as a motor being indicated at 15, and the other, which serves as the outlet when the device is used as a pump and as the inlet when used as a motor, being indicated at-16. Each of the enlarged ends 14 is held aga-inst rotation in its respective bearing 5 by set screws 17a, which are threaded through the bearing and engage in the wall of the enlarged end 14.

The inner end of each enlarged pipe end 14, and the outer end of each hub 49, are similarly formed to provide a fluid tight joint with the respective pipes 13, and per- Y mit relative rotation, and to thisend each has a stuning box with packing material 17 therein which is pressed into the stuffing box by a packing ring 18, the latter being clamped against the packing by bolts 19, secured to the end of the enlarged pipe end 14 or hub 49, and engaged through an annular flange 2O of the packing ring The cylinder 10 is divided, intermediate of its ends, into

separate compartments

23 and 24, by means of a diametrical partition 25, which is offset at the center as shown in Fig. 3, so that the diametrically opposite arcuate slots or

openings

26 and 27 communicate respectively with the

compartments

23 and 24, the ends of these slots being separated by the intervening wall portions 28 and 29.

A, plurality of partitions 30 are pivotally mounted in the casing 78-9, at equal intervals,` and adjacent the inner periphery of the drum 7, on shafts or bolts 31, which extend between and through the end walls drum 7 and cylinder 10 8 and 9, so as to support the partitions and also secure the end plates to the drum, and these partitions are engaged by springs 32, so that the inner ends of the partitions bear constantly against the outer periphery of the cylinder 10. suitable width to engage closely against the

end walls

8 and 9, of the casing without interfering with their pivoted movement, and the pivoted end of each partition is of cylindrical contour to fit and rock in correspondingly shaped transverse grooves 33, so that these partitions serve as valves to separate the annular space between the cylinder 10 and casing 7-8--9 into separate compartments and prevents appreciable leakage therebetween.

Obviously, as the cylinder lOand casing 78-9 are eccentrically arranged, rotation of either one, while the other is held stationary, results in a successive swinging of the partitions 30, those occupying the space where the walls of the cylinder 10 and drum 7 are closest together being swung outwardly as shown at the bottom of Fig. 2, and those occupying the space where the cylinder and drum are separated the' greatest distance being swung inwardly by their springs 32, as shown at the top of Fig. 2, and inasmuch as the inner ends of the partitions bear constantly against the cylinder 10, those intermediate of these two positions are at successively increasing or decreasing angularity to the inner face of the drum 7.

Of course, as the cylinder 10 or casing 7-8-9 revolve,lthe partitions 30 are constantly changing their positions, and the wall portions 2S and 29 between the

slots

26 and 27 are sufficiently long so that one, at least, of the partitions 30, is engaged therewith at all times, thus effectively separating one halt of the annular saace between the which half communicates through the slot 26 with the chamber 23) from the other half of the space between the drum and cylinder (which half communicates through the slot 27 with the chamber 24). n

Each of the partitions 30, at its free end, is oset so as to have a shoe portion 34 with two angular faces 35 and 36, the former of which fits and engages the periphery of the cylinder 10 as it rides along the slot separating portion 29 of the cylinder wall and insures suliicient engaging surface to prevent leakage between the chambers at opposite sides of the partition, and the latter of which fits and engages, for the same purpose, the periphery of the cylinder 10, as it rides along the slot separating portion 28 of the cylinder wall, these being the two pla-ces of Contact of the partitions 30 with. the cylinder wall where leakage is to be obviated to as great an extent as possible.

As a further measure to avoid leakage as These partitions are of the partitions ridealong the portion 28 of the cylinder wall, each partition is provided withan angular or rib-portion 37, on the outer face, which, as the end of the partition slides over lthe cylinder portion28, engages and 'is held against the cylindrical surface of the outer end ofthe preceding-partition, as shown in Fig'. 2.v Such engagement, however, by reason of the Acylindrical surface with which the rib v37 contacts, does not interfere withthe l`movement Vof the par-l tition, engaged by the rib 37, which is required to maintain its'frce .end engaged with the surface of the cylinder-10. In order to lapply power to this device 'for roperating-it as a pump or to transmit power therefrom, 'if usedas v`a motor, the side wall 9 of the casing 7-8-,7-9 has an annular flange 38, at the `outer iside, 4or a circular series of lugs, if preferred, to which a gear ring 39 is secured, the bearing support 3 being cut away at-6 to accommodate this gear,and a gear wheelf40 is also" keyed `atf41 on the tubular shaft 13, so thateach rotary-element of the device may receive or transmit power. 'When one of .the rotary elements is rotated, the Zother is usually maintained stationary, and for the purpose a number of set screws 42 are threaded through the bearings 4, and adapted, when the shaft 13andlcy1- inder 10 are to be held stationary, to 'be turned down into engagement with -countersinks 43 (see F ig. 9) "provided `therefor kin the shaft 13. These cap screws vare Withdrawn or removed,-when`the shaft 13 and cylinder l0 are to rotate. l

`Similar cap Vscrews 44 are threaded-into the

bearings

2 and 3,so as to engage similarcountersinks in the hubs 9 ofthe end plates Sand 9 of the casing of the device when the latter isto be held stationary.

In Figs. 10 and 11, I have shown a modiication of my invention which is the same as the previously described structure, except as to the partitions `45, and the same .reference numerals are used to designate the parts that are alike inbothl structures.

The partitions45, in this modified :structure have a long inner face-46, to ride on tlie t e slot separating portion 28 of the'cyhnder wall, and this face 46 is yformed on a radius of curvature equal to the 'distance of the aXis of the hubs 12 from the most eccentric point on the outer face of the cylinder '10, so that as such point comes into contact with the face 46, there is no further pivotal movement of the partition until this point moves out `rof contact with theface 46. The-back of the partition .also has a rib or angular flange 47, whichcoperates with .the cylindrical pivoted end of the preceding partition in the samemanner as the rib 37 of the I previous construction and as the partition,

whileriding over the slot separating portion Yvpreceding partitiony previous to the disengagement of Athe rib of such preceding partitionwith its preceding partition, thus insur- 'i ing `a thorough separation between the intakeand outlet compartments of the device.`

This separation is also assured by the increased extent of engagement of the surface with thewall ofthe cylinder `10 as `it rides overftherslot,separating portion'28 thereof` Theoperation is as follows: W'Assumingthat the device is to be used as apump, this ymay be accomplished by rotating Qeither the drum 7---8-49` or the cylinder 10 intheproper direction `while the other remains-stationary, or` by rotating -both in opposite directions. Gearing may bejconnected-Swi'th the gears l39and 40 to rotate either and` a'dapted,when one is rotated to hold jthe otherfrom rotation However, for the purpose of illustration, and to provide a simplesand reffective means of controlling the independent rotation of each,I have shown the 'seti screws 42 and 44, the former of which fareadapted tolockthe cylinder l0 from rotation and the latter of which similarly lock the casing 7 -8-9.

lIf it is .desired to pump by rotating the i casing 7-8'f9,-the set screws 44 are -withdrawn sufliciently to permitirotation thereof,

and the set screws 42 are turned down so as `to seat in the countersinks43 onfthe shaft or tube 13, and `thereby hold the cylinder 10 attached thereto in a stationary position.

Powerk is thenapplied to the gear ring `39, torotate the casing 7-8-9 inthe direction indicated by the arrow A in Fig. 2, and the pipe `15 isconnected with the source of fluid supply land thepipel connectedto convey thefdischarge from the'pump to the point desired. r

The rotation of the 'casing 7-*8-9 ,car-

the ends thereof being maintained in contact withfthe surface of the cylinder by the ten-4 sion` of thesprings and also,'at the points of greatest andv` least distance betweenl thecylinder 10 anddrum 7, whichfis the top and partments, certain ones of which communicate with oneanother through theslots 26" and 27 and. their

respective chambers

23 and 24, and itwill be 'observed that by reason of the intervening wall portions 28 and 29,

apartitionis'at all times engaged with the wall fof the cylinder 10 at the point 4of great-- ries the partitions 30 around the cylinder` l0, Y

est separation betweenfthe drum 7 and cylinder and another partition atlthe point of least separation of the drum fromthe cylinder so as to prevent communication between the compartments, between the partitions 30, which are in communication with the slot 26 and chamber 23, and the compartments in communicationwith the slot 27 and chamber 24. The chambers in communication with the slot 26 are graduallyenlarged as the drumv7-,-8-9` rotates inthe directionindicated by the arrow` A and fluid is drawn in through the pipeY 15, hollow shaft 13, cylinder chamber 23 and slot 26 toiill these constantly enlarging compartments, and provide what is hereinafter termed the suction side of the pump, andas each compartment reaches its greatest capacity, the preceding partition is riding over the wall portion 29 of the cylinder l() .and

the following partition moves over the Vwall portion 29 so as to interrupt communication with the slot'26 and isolate this compartment fromv the following compartments at the suction side of the pump.'lv

i The compartments between'the partitions 30 which are in communication with the slot 27 ,are constantly decreasing inl capacity as the casing 7-8-9 rotates in thedirection A and afford what is hereinafter termed the pressure or discharge side of thepump, `and as each compartment, which :passes overthe cylinder wall portion 29 andi'has been Visolated .from the suction sidevof the pump,

comes into communication with `the slot 27 it is gradually decreased in size `so thatthe fluid therein is forced out through the slot.

27 cylinder chamber 24,- Ahollow. shaft l13 and pipe 16. The continuing .rotationl of the drum 7-,8-9, and the resilient continuous enlargement of compartments at the:

suction side of the pump and transfer'of fluid therefrom to the discharge side of the.y pump, and the continuous diminution .in .size of the compartments at the discharge jside.. of thepump. effects a continuous passage of fluid through the pump. 1

Then the pumping isto beV affected byl rotating the cylinder, the set screws filare turned down to hold the casing 7-8-9 stationary and the set screws 42 are withdrawn sufiiciently to permit rotation of .the cylinder 10. Power is then applied to the Agear results in a' continuous diminution of theA compartments between the `partitions 30, in`

communication withlthe slot 27, and cylinder chamber 24,' and a constant yenlargement of the compartments inI communication with v the slot 26 and chamber 23, and-a constantvsuction of fluid in through thepipe 15, hollow shaft 13, cylinder chamber 23 and slot 26, and `transfer ofyfluid from the suction side to the discharge side of the pump, and exhaust of the fluid through theA slot 27, cylinder chamber 24, pipe 13 andpipe 16, as in the' previously described operation.

Obviously the operation of thecylinder and casing maybe combined, by applying power to both the

gears

39 and 40, so as to rotate fthe casing 4and cylinder simultaneously in the opposite-directions A and B respectively.` This, however, would probably not be necessary,exceptfperhapsin unusual cases, as the same result would be accomplished by increasing the rate of speed of either the cylinder'orcasing whilethe other was heldstationary. v

The operation of the device as a motor, it is thought will ybe readily understood without detailed description, as it is merely the reverse of, the operation of thev pump. When so used, iluidunder pressure is introduced through whatwas the discharge side ofv thepump, viz. through the pipe 16, hollow :shaft 13, cylinder chamber 24; and slot 27 and this fluid `acts tojenlarge the compartments,ybetween the `partitions 30, which are incommunication lwith the slot 27, and to eifect such enlargementcauses the cylinder 10orcasing 7--8.-9, lor both to rotate. By adjusting the set screws 42,7and 44,. r0- tation `of either the cylinder or casing orv both is permitted, and power .is furnished fromthe device by connections made with the gears 39 and 4:0. ff A VThe operation of the modified form of device Ashown in Figs. 10 and 11 is substantiaily the same as that described for the structure of Figs. 1 to` 9inclusive, except as `to the time and point of Contact of theV partition L.l5 with the cylinder wall and with one another, Vwhich was clearly pointed: outJ inl the description of4 this particular; structure, andv further description of itsoperation is. believed to be` unnecessary. f

vWhile 1 have shown'and'describedmy invention in a. preferred form,1 am aware that various .changes and modifications may belmade therein without departing from the principles ofV my invention, and I therefore donot 'purpose limiting the` patent granted hereon otherwise than necessitated by the prior art. i
