Specification of Letters Patent.
"ROTARY ENGINE ANDPUMP. I
F Application filed December 27, 1917. Serial No. 209,072.
To all whom it may concern:
. Be it known that I, GEORGE LANDER J AoQUEs,a citizen of the United States, residing at the city of Neillsville, in the county of Clark and State. of Wisconsin, have invented a new and useful Rotary Engine and Pump, of which the following is a specification.
My invention relates to improvements in rotary engines and rotary pumps. The ob- .jects of my lmprovements are, first, to provide a rotary engine operated by steam pressure instead of the striking force of escaping steam; second, to provide arotary pump that will elevate thefluid being pumpedby direct pressure; third, to provide successive cylinders forming a compound engine to use the expansive force of the exhausted steam from I each preceding cylinder; fourth, to provide a rotary piston with abutment pistons hinged thereto that will close against said rotary piston in the part of the revolution thereof bringing its outer surface nearest to the inner surface of the cylinder and that will open against the inner surface of the cylinder in other parts of the revolution ofsaid rotary piston; fifth, to provide guides and cam to I open said; abutment pistons; sixth, toprovide .tons operate; eighth, to
glands and stufling boxes for the operation of said guides without leakage seventh, to provide a proper outer casingor cylinder within which said rotary piston and; abutment plsprovide rings on said rotary piston to prevent leakage; ninth, to provide'rings or segments on the upper and lower edges of said abutment pistons to v preventleakage; tenth, to provide a bar or segment on I at the point wherethe outer surface of the rotarypistonv comes nearest to itto prevent v leakage; eleventh, to provide proper packing in the hinges of the in which y 1 is aside elevation of the device arranged as a triple cylinder engine; Fig. 2
(with the the inner surface of the cylinder abutment pistons to prevent leakage through said hinges.
I attain these objects by the mechanism illustrated in the accompanying drawings,
Figure is. a detailed view of the cylinder cover removed) and, the rotary piston, abutand cam. rollers operat- Fig. i is aplan view of '5 is a sectional view through top cover at ton 10, the latter having a gland and stufiin box 23 for each'guide 21. A cam roller'24 is take chamber; Fig. 7 is a section of the ro-.
Similar letters refer to similar parts throughout the severalviews. a
Referring to thedrawingFig. 2, 1O designates the rotary piston which is keyed to the shaft 30 which is loosely journaled in the lugs 11' and 12. See Fig. 3. The wings or vanes 13 are hinged to the piston 10 at 14,
, said hinge being provided with packing 15 Fig. 7) to prevent leakage through the hinge. The piston 10 is provided with piston rings 16 on its outer edge also the piston ring 17 on its inner surface, said piston rings being forced out to the inner surface of the top and bottom cover by the pressure through the port holes 8. i
The wings or vanes the packing segments 19, said segments are forced out to the top and bottom covers by pressure through the port holes 20. The %uides 21 are fastened to the wings or vanes by a pin and flange 22 securely fastened thereto and said guides run through the pismounted in the forked end of each guide 21 and travels against the cam 25 which is a' part of the bottom cover 26. The steam bar 27 is" bedded into the inner surface of the casing 26 and forced against the wings or vanes 13 to prevent any leakage toward the exhaust port 28, said bar being forced toward the abutment pistons by pressure entering through port holes 29 the casing 33 w as shown in Fig. 8.
Referring to Fig. 3, a crosssectional view showing the relative position of thepiston,
Patented Jane 24, 1919.
13 are provided with wings or vanes, guides and piston rings inside the cylinder, the piston 10'is keyed to the shaft 30 by the key 31 said shaft being loosely journaled through the hub 11 of the top cover 32 and also loosely journaled through the hub 12 of the bottom cover 26 said covers and the cylinder casing 33 being held in position bythe bolts 3%, theflower bolt 35 is also extended through'portions 36 of the bases ofthe main frames or supports 37 and co. l V
The frame bearings 38 for the shaft 30 are located at the upper ends of the frames 37. p ston r ngs, 1? are forced. by the pr s coupling 44 to intake chamber 45 of the second cylinder, .and so on through the cylinsure through the port holes 18 against the annular Sl1O11lCleIS1i39' on theiinnerifaees of top cover 32 and bottom cover 26. The wings or vanes 13 are hinged-to the p'iston, as'before described so that their rings-'19- engage the inner. 'faces ofithe top cover 32 and bottom cover 26.
Referring to Fig. 8Ihave shown a section through a portion of casing 33 illustrating steam bar17 and ports 29 on the inside face of the said casing, the dottedlines indicating pockets back of the bar to allow steam or fluid to enter and force the bar against the wings or vanes 13.
Referring to. Fig. l I havefishown' the complete engine arranged asa triple cylinder engine, the pnlley40 being mounted on the extremeend'o'f the shaft carried in the main bearings of frames 37 In operation steam enters through a valve 41 and passes into the intake chamber 42 Where it is distributed into two. chambers simultaneously between wings-orvanes of thefirstr'cylinder, making 4 its way through to the exhaust chamber 43 andthence' through the flanged ders 46, 47 and '48, and is finally exhausted through the exhaust pip'e.49. Thecylinders areprovided with drain cocks 50 'to-drain I the condensed water out of the cylinders and prevent pounding.
Myinvention may it will thus be seen, be
used as a singlecylinder steam engine using only-one cylinder or it may be used as a com oundjsteam en ineusin as' man succes'sive cylinders as may; bedesired. In my invention the rotary engine'maybe driven eitherby steam or any explosive gas.
' Itis also 'obviousthat-my invention may I be used as a rotary pumpby using only one cylinder, applying the power to the shaft 30 reversi g'the motion from what it wouldfbe. when usedlasa steam engine.
(Inoperation ,each' cylinder receives steam through the intakezchamberaof its cover. 32 I I between the:steam-bar.27 as seen in .Fig. 2
and the next adjacent-wing or vane; l3 'be-f yond the steambar. Thewingpr vane-13 in [question just (passed the steam. bar and :has already been, shifted on, hinge 14. to
hold its outer free end in engagement with the inner surface of'casing. 33by the cam 25 v and guide; 21, .sothat .the steam is thus free toexpand against saidwingor vane between the, same and the istationary steam bar 27 5 Thus if used as ,anenginethe steam rotates the piston lOand itused as aipumpthe fluid}.
g t ebepumpedjjis carried in the same-way, by J ,positiverotation of lthepiston 1 0 During this operation leakagelwill beireduced. to minimum, virtue of. the-rings,
and; ring ,;segments of jth'e. piston 110, and i wings'on vanesg13fand thepiston boxes for the guides 21, which are the movable parts 1.
