To all 'whom t may concern.'

Be 1t known that I,- Fnfinn E. VVINN, a citizen of the United States, residing at Haskell, in the county of Haskell and State of rleXas, have invented new and useful Improvements in Rotary Engines, oi which the following is a specification.

This invention relates to rotary engines or inotors, and particularly tol that type einbodying mechanical features Wherehy air compressed in a part of the cylinders is fed t0 and mixed With hydrocarbon in suitable form and the mixture then supplied in relatively controlled charges to a remaining part of the cylinders for combustion and generation of power to rotate a sha-tt coinmon to all thc cylinders 'and serving as the actuating means .for the compressing e1e ments and also as the power transmitting medium.

' The improved engine or motor has been specially devised for driving a motor vehicle, such as an automobile or truck, and. one. Object thereof is to provide an engine a com i pact forin einbodyinga plurality off cylinyais v group will eli'ect ders arranged end to end and provided with a common shaft entendi ng therethrough having rotating pistons fixed at different angles thereon in the respective cylinders, and to arrange the cylinders in groups for alternate internal combustion and air coinpression in the respective aircompression in another group, and capable ol" instant reversal' of operation to correspondiugly modify or change the, compression L froup to the combustion group and change the direction ot' the rotation of the main shaft by. a sim ple control. of theignition means in the cylinder groups. Another object o'f the invention is'to provide an engine or motor havingl grouped cvlinders with'a common shaft therethrough with pistons fixed'thereon and individually rotating in the individual cylinders and so arranged that the pistons' of the group of driving` cylinders will make one driving' lgroups so that one i stroke each for each revolution of the said shaft and give a resultant steady motion similar to a turbine drive. A further object of the invention .is to produce a very high air compression in one group of the cylinders for service iu the remaining group ot' driving or .internal combustion cylinders, and to deliver the air in a chamber common to all the cylinders wherein also the fuel is received in the form of a spray which is quickly changed to a vapor by the high speed and whirling motion of the air' I and thoroughly mixed with the latter, and thus make it possible to dispense with the usual Carlini-eter attachments or system.

lV ith these and other tages in View, the invention consists in the construction and arrangement' of the several parts which will be more fully hereinafter described and claimed. l

120, one with relation dierentiation 1n vanular'mounting of the -nerv portion of the This particular preferred application, however, does not exclude the improved motor or engine vfrom any other adaptation that may be desired.

ssentially the motor or engine comprises six cylinders divided into two groups, 5, 7, 9, and 8, 8, and 10, these groups being shown in the drawings to operate respectively as internal combustion or driving, and air comlnstead of six cylinders, the num er may be increased to eight, twelve, or any corresponding multiple. The cylinders are formed or deiined by opposite end walls 11 and 12, a central group dividing wall 13 and cylinder partition walls 14,

together with cylinder inclosing casings or sides having cylindrical or circular piston chambers 16 of suitable dimensions, the wall 13 being 4tl-iicker than the remaining All of walls and cylinder casings or sides are suitably connected or joined in a strong and durable manner, and the joints formed between these several parts will be rendered tight and non-leakable by introducing therein any preferred form of packing, washer, gasket lor other joint sealing means. The walls and casings or sides also extend above the location of the piston chambers in the casings, and will be constructed as hereinafter specified to provide for acnessories included in the general organization of the improved motor or engine. f

Extending through all 14: in suitable bearing means and in bear.- ings 17 provided as parts of the end walls 11, is a main orpovwer shat 18 which centrally passes through the cylinder chambers 16, and carries

pistons

19, 20 and 21 in the chambers of the respective cylinders, 5, 7 and 9and pistons 22, 28

chambers ot the

respective cylinders

6, 8 and 10. The

pistons

19, 2G and 21 are all arrangedat diii'erent angles, or, at an langle' of to the other. r1`his the wallsl 13 and pistons is simi arly and successively carried out inv the arrangement of the pistons 22, y23, and

As all the pistons are duplicates in construction, a speciic description of one will sufice. Each piston comprises ,essentially a mediumly hard metal body 25 preferably of oval f 'rm and fixed eccentricaily on the main or 'power shaft 18, the body bein@r enveloped lby a hard metal wear sheat or casing 26. The adjacent sides of the end and partition walls of the cylinders above and below the main or power shaft are formed with recesses 27 to receive the inbody 25 which is thicker than the remaining outer portion of the Said body, the outer' or thinner portion 28 ofthe hody movingor rotating in a more confined outwardly by cross springs and 24Cv in the' space between the cylinder and partition walls. The outer thinner portion 28 of the body 25 continues to the outer smaller end of the piston and has two side packing;- plates 29 nioi'ably set therein and pressed 3() seated in said outer smaller end in suitable relation to set up a yielding cont-act between the plates 29 and the adjacent poitions ot the inner sides ofthe said end and partition Valls. By means of these packing plates a tight working joint of a non-leakable character is maintained between the opposite ends of the outer portion of the piston and the adjacent walls. In the outer reduced or smaller end ofwthe piston between the plates 29, sockets '3'lareformed to receive inwardly projectingstems 32 of a packing bar 33 which extends fully over the outer reduced end of the piston and continually bears against the inner surface of the side of the piston chamber. The bar 33 is given a uniform outward and yielding projection by springs 84 surroimding the stems 32 in the sockets 3l, Said springs having their opposite eX- tremities 'respectively bearing against the bar and inner end walls of the sockets. The sockets also have oil ducts or bores 35 extending thereinto and outwardly. through the sheath or casing 26. The shaft 18 is also lubricated by means of ducts or bores 37 extending therefrom outwardly through the walls l1, 13 and lfhllateral or subsidiary bores or ducts running from the ducts or bores 36 tonditlerent portions of the opposite sides oli all the pistons andthe plates 222 thereof. The bores are supplied with suitable lubricant by cups 38 in communication therewith and mounted on the eX-. terior portions of the

walls

11, 13 and 14.

In, each cylinder above each piston is a swinging. cut-oill abutment 39" extending fully across the width of the cylinder chamber, the abutinents being in reverse positions the two groups of cylinders '5, 7 and 9, a"

d

6, 8 and 10 to provide for reversal of the operation of the motor or engine and particularly the shaft 18. All of theabutments 39 arev similar in construction and have a like mounting in the cylinders.- The upper portion of each cylinder to one side of the vertical center thereoi' has acylindrical seat 40 formed therein to receive a,. joint trunnion l1 at the outer end of theabitment 39, and from said seat a recess (t2 extends inwardly through the upper portion of the cylinder and opens downwardly"'intov vthe piston chamber,

said recess havin the lsame As contour as the abutment' 39 whicV [is: ressed ment 39 lis ot concave cnntour-"a dghas an gages' y 1 lwhereby a thorough arc corresponding to and operating to regularly com-plete the circular contour `of the side wall of the piston chamber and with which the outer reduced'end of the piston has contact. The abutment 39 has an inner free end'44 which is reduced and so shaped that a piston engaging angle is formed, the inner concave side 43 and a portion of the reduced end 44 including the piston engaging angle 45 being covered by a. hard metal wear sheath or `casing 46. vThe angle 45 with its 'sheath or casing 46 is at all'times held in contact with the sheath or casing 26 and the packing bar 33 through the medium ot a plun ger 47 bearing on the upper side ot'- the abutment 39 adjacent to the trunnion 41, said plunger thereof being disposed at an anglev oi inclination to provide for a practical contact thereof with the abutment'in view of themovement and variable position of the latter. The plunger 47 mounted in a cylindrical casing 48 .secured in and extending upwardly and outwardly through the piston cylinder. This casing 48 has alowerl guide member 49 therein for the plunger, and in its upper end said casing is also provided with an adjustable` screw plug 50 formed with 'a centrally projecting tubular stem 5l within the casing and into 'which the upper portion of the plunger movably extends. The plunger 47 has an intermediate stop or collar 52, and betweenthe latter and the plug 50 a spring 53 is mounted and exertsl a strong downward expelling, pressure on the plunger and the abutment 39 'through the plunger. The tension of the spring 53 may be regulated as found necessary by adjusting the plug 50 which is exteriorly exposed in the outer end of the'cylindrical casing 4H. The abutment 39 has a lubricant duct or bore 54 extending through the same and also through the trunnion 41, and is supplied by an intersecting outwardly opening d'uct or here in the Ipiston cylinder, the said duct or bore 54 being in feeding communication with the wall. ducts hereinbt'it'ore described.

The duct or bore 54 alsointersects with and opens at its inner terminal into a downwardly inclined outlet duct 56 through the inner reduced end 44, anglel 45 and sheath or casing 46 of the abutment 39, the duct or bore being always lopen to the outer surface of the sheath or casing 26 of tliepiston and lubrication is up between the angle and portion ot' the sheath. or casing 46 thercovcr and the piston to produce easy movement of the reduced end of thc abutment and its sheath over the piston sheath or casing 26 and thus reduce wear on these parts. the duct or bore 5G is located slightly in rear et the` maximum projection of the angle 45 and the sheath or casing 46 of the abutment and the supporting parts .ating cylindrical charge The lower outlet of' 39 to obviate cloggingthe said outlet and obstructing' the through to the sheath or casing 26 of the piston.

The. -

walls

11, 13 and 14 continue above the cylinders and arevreduced in width to provide upper substantially rectangular extensions 57, and between these walls casings 58 are interposed and tightly jointed therewith at their oppositev ends, as shown by Fig. 3. In the lower portions of the extensions 57 and the casings 58 a circular valve chamber 59 isv formedl and extends full length of the motor between the extensions of the end walls 11 and 12, and extending through the top. portions of the cylinders below and communicating with the abutment recesses 42 are vertical passages. 60. Iiithe upper portions `of the extensions of the walls 14 and extending .through the latter in similar structure on opposite sides of the dividing Wallv 13 are two

chambers

61 and 62 divided by a central vertical partition 63, the lower portions of .the chambers being open respectively, as at 64 and 65, to recesses 66,` there heilig one of these recesses to each cylinder and piston chamber below. The partition 63 extends downwardly through and divides the recess 66 into two parts, the said divided 'recesses opening' into the upper portion of the valve chamber 5S). Over the chamber G1 is at the rear and the chamthe cylinders 5 7' and 9V passage ofthe lubricant there -Y ber 62 at the front, and over the cylinders- (i, 8 and 10 the positions of these chambers f formation of independent ducts or com-' nmnicating passages 67 and 68 'formed in the upper extension. ot the dividingwall 13, as shown particularly by Figs. 2 and-3. Both ot' the chambers 61T and 62 receive compressed air from the cylinders acting as air con'iprcssors, but only one of the chambers, namely chamber 61, receives the' fue] in a 'manner which will be hereinafter explained, and in view of the open bottom construction of the chambers and the recesses 66 and valve chamber 59 hereinbefore explained, the compressed air from the cylinders acting as compressors will be forced upwardly into both

chambers

61 and 62. In the valve chamber 59 is a continuously opercontrolling valve 69 having at intervals throughout the length. thereof between the extensions of the end walls 11 and 12 channels 70 and 71` the channel 71 being of less width than the ehannel 70 and the two channels separated by with such packing devices as may 'be found compression 'from the group t5 ythrough the upper portion necessary to prevent leakage around the valve or between the latter and the wall o the chamber 59. The valve 69 also has a shaft 73 extending citrally therethrough and projecting outwardly through the eX- tension of the end wall 12 where it is mounted in a suitable bearing 711 and on the outer end thereof is a Vsprocket wheel or other suitable driving element '75 eiigaged by an endless chain or other belt Y6 also trained over a similar device 78 keyed latter shaft projecting outwardly through a suitable bearing 79 in the end wall 12as particularly shown by Fig. 3. By means of this driving mechanism the valve 69 is actuated relatively to the rotation of .the

shaft 18 and the pistons tliereo,'the channels '.70 and 71 of the valve 69 heingso ar ranged around the valve or in such positions relatively tothe latter that the respective piston chambers will be regularly charged with the mixture of air and fuel under conipression, or, the

chambers

61 and 62 will be charged from the cylinders with air under of cylinders operating as air compressors. The istons 19 by their variation in angular application to the shaft 18 will always be inproper position in the group of cylinders arranged as internal combustion cylinders to receive the charges successively thereagainst and he driven by the ignition and explosion of said charges, and the pistons of the air coinpressing cylinders in view of their successive singularity will also effectively' compress air and force it upwardly into the

chambers

61 and 62 by the communicating operation of the valve 69 through the channels 70 and 71 with the compressing cylinders and the said chambers 61 and G2. A storage tank `8O for fuel and air under compression is connected by a pipe 81 to the chainher 61, an outwardly opening check-valve' 89 of suitable structure being ii troduced in the said pipe '81, and when the pressure in the chamber 61 is greater than a predetermined degree, the checlrfvalve 89' is :forced o en and the compressed air having the nel mixed therewith is forced through the pipe 81'into the tan 80 and retainedlr or reservoir in this tank for starting1 purposes. To the bottom of they tank or reservoir 81 is connected and extendsr inwardly of the one cylindei' casing adjacent thereto and connects with an elongated duct or bore 84. having communication by passages 85 with the valve chamber of the passages and whereby in startirig up the mot/0r or engine the charges of fue and air in proper proportion and under compression may be supplied to the valve chamber 59, a valve 86 being introduced in driving sprocket or on the sha-1518, 'the 59 at intervals to one side,

centrally thereinto and terminating in a sump or depression 889' in the bottom closure- 88 to make an air cushion more available in thereceiver. The pipe ortube 90 is intersected by a fuel supply pipe 91 continued in *A the form of a supply or spray pipe 92 proj eating through shown by Figs. bei' 611,v where it terminates in an upward projecting spray nozzle 93. rlChe Jcedri the fuel through the pipe 99 from the pipe 91 is controlled by a needle valve 9i which may be regulated at will and is of the form shown by Fig'. 1li and will be hereinafter specilically described.

The pipe 91 which. serves' as a common supply pipe, connects with a conduit or pipe 99 through a three-way valve 100V in the latter. The conduit'or pipe 99 forms part or' a multiple pump organization which is constructed andA arranged to pei'- forni different Apumping operations relativelyto separate parts of the motor or engine cylinders'v and the receiver 87. The pump 1,02 is constructe as a reversible rotar Elmas-,sand throughwhich extends acom-J inon shaft 106, the pump having a suitrble or inclosure 10? in which the several royliiulers are defined and the sha-ft 106 suitably mounted, the i wardly through one vthrough asuitable bearing 108, and has a sprocket or other drive wheel 109 thereon over which passes a belt 110, clearly The

pipes

91 and 92 through the pipe 90 have communication i seated at the juncture of the pipe 95 95 opened to permit When the pump having `four cylinders 101, 103, v

shown by Figs. 1 and 2. The drive Wheel 109 in the present instance is in the form of a sprocket and the belt 110 in the forni of a sprocket chain, said latter belt being also trained over a sprocket Wheel or other suitable driving' element 111 on the outer cX- treuiity ot the shaft 7 3 of the valve (Si) and whereby the operation of the pump will be 'in timedrelation 'to the operation of", said valve. As hereinbeore noted, the pipe 91 coi'xnerts with the conduit or pipe 99, the latter serving as means for conveying` to the pipe 91, when the valve 100 is suitably adjusted, the fuel constituents and .vater from the several` cylinders 101 to 10ft inclusive, and in each cylinder is a rotary piston 112 which is disposed to rotate in a piston chamber 113 oi' each cylinder, the pistons 112 being flisposed atl varying angles on the slial't 100 in the successive cylinder chambers. Above each piston 112 a pair of

abutments

1,1/1- and\115 is mounted, the-abutments having` their inner ends normally engaging each piston and their outer ends fulm ciiun'yed or positively mounted, at 116, in the ogn'iosite 'walls oi each cylinder chainbej. the abutments in double form beingf proded for a reverse operation oi the chan'zber the o'ieration oi? the inoA or engine, h inbeore dest ibed, with non 'the pump eo-aets, and 'forms an s 'e itial accessory. Each ot the abutments 1141 and 115 is constructed similarly to the abutineuts 32, hereinbefore. described, and has a pressure means cooperating therel@ oni-before described in conwith the abutinents 39, and operatto maintain the ends oit the abutnients 111i and 115 in. continual contact with the outer surface of the pistons 112. Each piston chamber is provided with an inlet pipe 101 and an outlet pipe 101, respectively communicat-ing` with the lower and upper portions of each chamber and connecting; with the respective inlet pipes 101" of the chambers and cylinders 101 to 101 inclusive are supply pipes .117, 118 and 119, between 'weich and the said inlet pipes 101a upwa opening cir valves 120 are iin i which. pre ent a 'back iiow of the liquid from the chambers oi the cylinders 101 to 101 inclusive to the sources ot supply, the outlet 1011D also each having upwardly (mening check valves 121, similar to the valves 120, the valves 121 preventing,l back flow and back pressure affecting the chambers and the cylii'iders 101 to 1.01 inelusive through. the said outlet pipes.- The in accorda nee. witi '.supply pipes Y1.17, 118 and 11i) nespectively engage or connect vwith the gasolene supply source'122, the kerosene supply source 123 and the water pipe 124 leading from a suitable tank or other sourceof supply 125. A.

-cut-oii valve 126 is introduced in each pipe sive and each having a lower elbow conneeted to the check valve 121 which is be-` tween the same and the outlet 101,b of each cylinder. Each regula-tor consists of two uertica] tubular limbs or pipes 129, the first regulator or that disposed over the cylinder 101 lnwing1 two upright tubular limbs or pipes 129 and 130 with an intermediate air chamber 131. all in communication with the elbow, the elbow 128 over the cylinder 102 haring similar upright tubular limbs or pipes 132 and 133 with an intermediate air chamber 13-1, all in communication with the adjacent elbow 128 and the elbow 128 over the third cylinder 103 having upright tubular limbs or pipes 135 and 136 and an intermediate air chamber 137. The upright tubular limbs or pipes 129, 132 and 135 are connected to the conduit or pipe 99, each of the tubularlimbs or pipes just mentioned,

prevent back pressure and back 110W from the cdnduit or pipe 99 into the several u right limbs or pipes 129, 132 and 135. The upright tubular limbs or pipes 130,133 and 136 constitute vertical cylindrical chambers each edntraeted at its lower extremity, as at 110, 'to forni a valve vseat for a valve 141 haring a stern 142 and secured to an. upper adjusting pluto` 143 between which and the valve 111 a spring 144 surrounds the stem. 142 and 'causes the valve to be normally seated and to close an outlet 145, the outlets oil the respective upright tubular limbs or pipes or cylii'iders 127 pipes 116, 'i4-7 and 1118 respectively connected thereto and extending downwardly and joined to thesul'iply

pipes

117, 118 and 119 and whereby an excess or overflow and eireulation of the liquid entering the several chambers 113 of the cylinders 101 to 103 inclusive may be forced back to the source of supply. i The

air chambers

131, 134 and 137 operate in conjunction with the chambers having' back 110W.

after the. manner of the compressed air cylinders of ordinary pumps and maintain a proper working pressure. When the pressure exceeds a desired normal pressure the 5 valves 141 of each regulator will be auto matically opened to clear the outlet 1-13 and permit of an overflow back through. the

respective pipes

116, 117 and 118 to the pipes 117,

r

118 and 119 and whereby the fuel `0r .10h fuel material fed to each chamber 113 of the cyli'n( l,ers 101 to 103 will be returned to its vvproper source of supply.

It will be understood that the springs lll-1, cooperating with all of the valves 111, will be set or adjusted to resist a certain predetermined and desired maximum pressure so that the valves 111 will not open except when an excessive pressure is reached. 1t will be seen that the short tubular limbs or pipes 129, 132 and 135 are so joined to the conduit or pipe 99 that the fuel or fuel con- 'lstituents forced into the tubular limbs or pipes '1132, 135 may be cut-oft from 'the fuel or fuel' element forced through the limb or pipe 129 by properly adjusting the threeway valve 190 and when the latter valve is so adj Listed communication will be established between the limb or -pipe 129 and 'the common feed or supply pipe 91, and under such conditions gasolene from the source 122 will be pumped upwardly into the .conduit or pipe 99 and the feed pipe 91. When the valve 100 is adjusted to shut-oft communication between the limb or pipe 129 and the pipe 90, the limbs or pipes 132, 135 will be opened to the pipe 80 and under these conditions kerosene or distillate will be forced upward through the limb or pipe 182 and water will pass through the limbv or pipe 125 and bemiXed in suitable proportions accordin, ,0 to the adjustment of the needle Valves 138 and the mixture then forced from the conduit or pipe 99 upwardly through the feed pipe 91. The control of the fuel or fuel element or constituents and water will be regulated by thc adjustments of the supply valves 126 and during the periods when the gasolene is not used its pumping' pistou and cylinder will be inactive as a means for raisingc;` or forcingthe same upwardly into the conduit or pipe 99 and feed pipe 91` and conversely when the kerosene or distillate piston and cylinder and the water diluting' piston and cylinder are in operation there will be no mixture of the `asolene therewith as the ,L'asolene supply and pumping` means therefor will then be cutoff. The chamber of the eylinder 105 is somewhat larger than the chambers of the cylinders 101 to 103 inclusive and likewise the

pistou

1,12 of this enlarged cylinder is of similar and large proportions, this part of the pump having the water main or enlarged watcrsupply pipe 121 connected to the lower portion thereof and also pro c vided with a similar enlarged outlet 149, a check valve 150 being introduced between the outlet pipe 129 of the chamber of the cylinder The groups of cylinders. 5, 7 and 9 and 6, S and 1G and a portion of the upper reduced extensions of the walls are provided witi aA water chamber construction, as at 151 and the pipe 111-9 is connected to this water jacket construction, the check valve 150 preventingl back flow of the water forced upwardly by thc piston of the cylinder 105. It will be understood that the water jacket construction will be supplied with a suitable outlet or return pipe running back either 8G to the tank'or source of supply 125 or to some other point as may be desired, so as to complete the circulation of the water through the water jacket construction and maintain the cylinders and the upper portions of the wall extensions at a tempera-- ture advantageous to the operation of the motor as a whole.

The fuel, either gasolene, kerosene or distillate and water passes from the pump by 90 way of the pipe 91 to the receiver 87 and rises in the latter until the. air pressure in the upper portion of the receiver becomes sufficient to force the uid from the receiver into the chamber G1 where it connning'les with t-he compressed air, the air pressure in the upper portion of the receiver forming a flexible air cushion which will cause a continuous spray of fuel into the said chamber G1 and when this pressure is reached in the receiver' the fuel passes almost directly to the motor `chamber' 61, by way of the pipe 92, and from the fuel supply pipe 91 until cut-off by the three-way valve 100, and in the event of excess pressure being generated during this operation in the pipes 91 and 92 sufficient to overcome th'e resistance of the spring 97, the valve 96 `will open and permit of an overflow through the pipe 95, said overflow running back to the pipe 117, if gasolenc' is used, as the fuel, or by way of a' branch pipe 152 back to the pipe 118, if kerosene or distillate and water are used, a l valve 153 being disposed in the pipe 95 below the pipe 152 and between the latter and the supply pipe 117 and whereby kerosene or distillate and water may be prevented' from passing into the gasolene source of supply 122 an d insure a return of the kerosene or distillate and water to the pipe 118 and then into the source of supply 123.

It will be understood that 'by Aadjusting` the needle valves 138 any amount of gasolcne, kerosene or distillate and water may he permitted to pass to the conduit or pipe 99 as may be necessary to provide an advantageous fuel or fuel mixture' which is A finally fed by the pipe; toV the 90 and ieceiver'S?, or, under the conditions just specified, almost directly to the chamber 61 of the motor or engine through the spray pipe 92.

Each group of motor orl engine cylinders and pistons will be supplied `with spark plugs 137. These plugs in the

cylinders

5, 7 and 5) (which in the present instance are arranged as the internal combustion or driving cylinders) are disposed at the right of the upper portions of said cylinders .in the same position in all of the cylinders of this particular group, and at a point about opposite to the posit-ion of the sparking plugs 137 in these driving cylinders the casings of the cylinders are'each provided with an' exhaust outlet 138 communicating with an exhaust pipe or passage 139 which is formed by boring through the cylinder casings and intervening Walls to the central dividing wall 13. 'In the group of cylinders G, 8 and 10 (which in the present vinstance are shown arranged as compressing cylinders) the sparking plugs are at the leftof the several cylinders and the exhaust outlets 138 and exhaust bore or duct 139 are located at the right so that there will be no interference with th passage of the compressed air from the cylinder chambers into the

chambers

61 and 62 above. The exhaust ducts or passages 139 may communicate with a common outlet pipe 140, asshown by Fig. 4. The operation of the spark plugs 137 will be controlled by means of a suitable timer so as to render either one of the groups of spark plugs active in accordance with the direction of movement of the shaft 18 and pistons 19 that may be desired, and in reversing the movement of the pistons in the respective cylinders it is only necessary to cut off the one group of spark plugs and render active the remaining group or groups of spark plugs.

Each of the needle valves used in connection with the improved motor or engine and pump organization associated therewith is of the same struct-ure and one of them is shown in section by Fig. 14 and comprises a casing 154 with an-inlet 155, an outlet 156 and an intermediate valve seat 4web or member 157 with a. tapering bore 158 forming the means of communication between the inlet 155' and the outlet 156. A plug 159 is rotatably mounted and secured thereto in the necked portion 160 of the casing and is provided with :n.tapered extremity 161 to engage the bore 158 of the valve scat 157. As hereinbefore indicated this valve may be 4 positioned either with the plug 159 in up right position or in horizontal position and in each position the operation will be pre cisely the same and the quantity of fuel or fuel mixture passing therefrom will depend upon the amountl of exposure of the bore 158 bythe tapered extremity 161 of the plug 'through the )assages `tll the charge is exposed dotted lines in

trolling valve 69 will have closed the will be ofsuitable 4type and of the most improved form adapted to perform the functions of such devices at the points where they are installed.

The operation of the motor or engine is simple and when it is l`desired to start the same the supply of mixed air and fuel will be transniitted'- from the tanl; S() by means ofthe pipe 83 to the valve chamber 59 and through. the'medium of the Valve 69 will be regularly discharged 60 into the cylinder chambers 16 ehindv the abutments 39 and against the portions of the pistons exposed by the lsaid abutments and operate to force the 4pistons around in regular succession unto the action of the spark plugs when the usual explosion will ensue and the piston lie-driven around and the exhaust effected through the outlets 13S. After the engine has started, the gasolene may be supplied to the chamber 6l by means of the pump and pump organization and connections hereinbefore explained, and after the cylinders have been fully heated the gasolene supply will be lcut olf and the keroseney or distillate of lower volatility with water will be supplied to the receiver 87 and from the latter tothe chamber 61.

here Vis no communication between the the chamber 62 being an air receiving and 'storing chamber andl charges of the fuel are regularly delivered by the channels 7l, and ahead of these c larges of fuel a protective air cushion is provided by charges of air from the chamber 62 carried around by the channels 70. The admission of chargesof air by means of the channels 7 0 into the cylinders ahead of the charges of fuel mixed 'with air which are safety to avoid any l of prenlature explosion, and though a premature explosion in this particular motor or engine would not cause any damage, as the pistons are always rotating in one direction, the effectiveness of vthe engine is much better when' there is no premature explosion. Briefly consideringthe position of the pistons as illustrated in Figs. 4 to 6 inclusive, relatively to the compression cylinders, as shown by Figs. 7.to 9 inclusive, it will be understood that, as the first cylinder of the left is charged n tween the latter and the 39 around to the sparking plugs, the piston in the compressing chamber to the extreme rightwill have justconipleted its compression' operation or stroke vand will have closed the swinging .abutment 3S) thereinto a'nd at the same time the rotating conpassageway leading-from the combustion chamadjacent abutment or

The piston continues to rotate until it cannot close the i abutment,A when tlielatter will gradually open into the position shown by Fig. f-,t and permit a re-chai'ge of the cylinder, the abutment following around on the surface of the piston as clearly indicated by Fig. 5 during the rotation of the said piston and there*- `'charge until the'latter l power or impelling force against the piston.

Two of the pistons in the grou of iners. will thereby giving a steady Ino-v t'oii similar to a turbine motor or engine. For each revolution of the main shaft there Will be three separate driving piston strokes and each stroke `will be two-thirds of a circle. It will also ne understood that the improved lmotor or engine compresses six volumes. of air into one volume before it en-J the combustion chamber, and owing to compression there Will be .a economy in the 'use of fuel. motor or engine gives the besl-J the highest rate of speed compatible with the fuel expansion, as there' is no pounding or vibration to put it out otl lorder and inl tact the. operation of the improved motor or engine is practically that ol a turbine, With the exception of the swinging abutments. The niotor or engine as hereinbefore described is also powerful in its operation and is comparatively compact and may be effectively used for the p. vfticular purpose for which it has been devised.
