Specification of Letters Patent.

Patented Mar. 8, 1910.

Application led December 9, 1907, Serial No. 405,801. Renewed August 2, 1909. Serial No. 510,883.

To all whom 'it may concern:

Be it known that I, GEORGE J. VEBER, a citizen of the United States, residing at Kansas City, in the. county of Jackson and State of Missouri, have invented certain new and useful Improvements in Explosive-Engines, of which the following is a specification.

My invention relates to improvements in explosive engines.

It is particularly adapted to engines of the turbine type.

The object of my invention is to rovide an explosive engine in which the ful explosive force of the exploded charge is suddenly discharged against the rotary piston. This effect is produced by exploding the charge in a. closed chamber and after ignition permitting the ignited charge to be suddenly discharged against the lplsto'n.

In a pending app ication tiled by me and having Serial Number 285,215 there is described and claimed an explosive engine having certain features of construction which are common to the construction which is herein described, and to such features as are claimed in the aforesaid application I make no claim in this application.

The novel features of the present invention are hereinafter fully described and claimed.

In the accompanying drawings illustrative of my invention, Figure 1 is a vertical section on the dotted line c-v-cl of Fi 2. Fig. 2 is a vertical section on the dotte line c-b of Fig. 1. Fig. 3 is a view partly in front elevation and partly in vertical section of a portion of the mechanism for actuating the valves controlling the inlets and out-let to the explosion chamber. Two positions of the parts are shown in solid and dot-ted lines respectively, and a modified means for controlling the retraction of the outlet valve of the explosion chamber is shown. Fig. t is a view of the engine partly in vertical section and partly in elevation. Fig. 5 is a View of thc engine, partly in horizontal section and partly in plan, a portion of the fuel oil feed mechanism being removed. Fig. 6 is a top view of some of the vparts connected with the valve in 'the supplemental chamber. Fig. 7 is a side elevatlon of the crank for rocking .the supplemental valve shaft. Fig. 8 is a side elevation of the bell crank lever mounted on the shaft of the valve located in the supplemental chamber. Fig. 9 is a side elevat1on of the wiper lever. Fig. 10 is a side elevatlon of a modified form of cam. Fig. 11 1s a vertical section through valve casing 7 9.

imilar characters of reference denote similar parts.

1 denotes a cylindrical iston having peripheral pockets 2 which form blades to receive the lmpact of the propelling fluid.

3 denotes a horizontal central shaft supporting the piston and rotatively mounted in earmgs provided at opposite ends of the casing a which encircle's the cylinder 6 in which the piston 1 is mounted. Intermedlate the casing 4 and the cylinder 6v is a water space 5. Above the cylinder 6 and connected therewith by an outlet 7 is vanexplosion chamber 8 having two inletpOrtS, one of which is denoted by 9, the'other will be described hereinafter. In the explosion chamber 8 is mounted a rock valve 12, adapted to cover and uncover the ports 7 and 9. Adjoining the explosion chamber 8 and connected therewith b the inlet port 9, is a supplemental chain er 10 having mounted therein a rock valve 11, adapted to ope'n and close the port 9 independently of the valve 12.

The valve 12'is Wide enough to cover simultaneously ports 7 and 9. Each of the valves 11 and 12 is provided with a-peripheral groove 13 for receivin the charge of air or fuel, as the case may e. l Intermediate the ends of said groove is the valve face 14 fitted to the inner wall of the chamber in which the valve is located. Each valve is preferably hollow and has extending into its interior through a central, horizontal, tubular extension 15, a horizontal tube 18, through which a cooling iiuid, such as water, is conveyed into the hollow space ofthe valve. The extension 15 extends through the casing 4 and has fitted on its outer end a cap 16 having a lateral discharge outlet 17. Encirclin each extension stem 15 is a spring 19 which ears at one end against the casing 4: and its other end against the cap 16. The springs 19 hold the valves 11 and 12 tightly against the inner walls of the. cylinder so as to prevent leakage of gas around the stems 15.

For rocking the valves 11 and V12 the following described arts are rovided :-A horizontal rock s aft 20 w ich extends through the forward side of the casing 4 has its rear end secured to the center of the forward end of the valve 12. VA bell crank lever 21 is secured to the outer end of the shaft 20 and has one arm iivoted to the upper end of a connecting ro 22, the lower end of which is pivoted'to the upper end of a bar 23, which is reciprocative 1n a guide 24 provided on the forward side of the casing 4. On the lower end of the bar 23 is mounted a roller 25 which bears against a cam 26 secured upon and rotative withthe shaft 3. The roller 25 is held agains fthe cam 26 by a coil spring 27, one end o v-which is secured to the lever 21 and the other arm of which isV secured to a pin 28 secured to the forward side of the casing 4. The cam 26 serves to rock the valve 12 to a position covering the port y7, -while the spring 27 retracts the said valve to a position covering the port 9. ,j Y

For regulatingr the degree to which the port 7 is opened by the valve 12, so as to obtain the greatest efficiency in the expansive force of the ignited charge, the lever 21 is provided with a vertical arm 29 adapted to strike a horizontal screw 30 mounted in a projection 31 on the forward side of the casino' 4. By adjusting the screw 30 toward and fiom the arm 29 the stroke of the lever 21 and valve 12 may be adjusted. A lock nut 32 on the screw 30 is ada ted to bear against the projection 31 to hol the screw in the adjusted position. Y

A horizontal rock shaft 33 having its rear end secured to the forward end of the valve 11, extends through the forward side of the casing 4. Pivotally mounted onsaid shaft 33 is a bell crank lever 34 having one arm pivoted to one end of a connecting rod 36 b v a horizontal pin 35 secured to said arm. The other end of the rod 36 is pivoted to one of the arms of the bell crank lever 21. 0n the other arm of the lever 34 is pivoted a pawl 37 adapted to engage a tooth 38 on the lever 39 keyed on the shaft 33. To the' lever 39 is pivoted the upper end of a rod 40 the lowerend of which is pivoted to a piston 41 vertically reciprocative in a cylinder 42. The piston 41 is a weight which serves to move the valve 11 to a position closing the port 9.l The cylinder 42 serves as a dash pot to slow the movement of the piston 41.

With each rotation of the piston 1, when the engine is not running faster than a certain predetermined speed, the cam 26 through the intermediacy of the roller 25,

rods 22 and 23, lever 21 and rod 36, swings the bell crank lever 34 so that the pawl 37 engages the tooth 38 of the lever 39 and thereby rocks the valve 11 to a position uncovering the adjacent end of the port 9, thus l permitting fluid to pass from the supplemental chamber 10 into the explosion chamber 8, the valve 12, at this time, being swung to the position shown in Fig. 1 and covering the port 7. After the raised portion of the cam 26 passes the roller 25, the spring 27 swings the

levers

21 and 34 so as torock the valve 12 to first close the port 9 and then open the port 7, and permltting the piston 41 to swing the valve 11 to cover the other end of port 9. While the valves 11 and 12 are in positions closing the ports 9 and 7 and before the port 7 has been opened, the compressed air which has been admitted from chamber 10 to chamber 8 mixes with fuel which has been introduced into chamber 8 as will be hereinafter described. The mixed fuel and air is then exploded While all the ports communicating with chamber- 8 are closed. The valve 12 then uncovers port 7, thus permitting the ignited charge to pass therethrough into the cylinder 6 and against the peripheral blades on the piston 1, thus causing rotation of the piston. The continued rocking of the valves 11 and 12 uncovers the port 9 thus permitting a fresh charge of compressed air or compressed mixed air and hydrocarbon va or to pass from chamber 10 into the explosion chamber 8, the valve 12 having previously covered the port 7.

To than t e proper rate of speed, the following described mechanism is provlded. Pivoted on the shaft 33 outside the lever 39 is a lever 43, which is governor o erated by any suitable mechanism connecte with a rod 45, which is pivoted to the lever 43 and serves to swing the lever 43 to and fro. The lever 43 is provided with an inclined upper side adapted to nstrike the pin 44 on the pawl 37 will miss the tooth 38 on the lever 39. When the pawl 37 misses the tooth 38 the lever 39 will not be swung so as to rockv the valve 11 to a position in which the valve will uncover the portl 9, and the charge contained in `chamber 10 can not pass as usual into the explosion chamber 8. As the speed of the engine becomes reduced the lever 43 will be swung by the rod 45 to a position in which the inclined face of said lever will not raise the pawl 37 to clear the tooth 38, and the pawl again engaging said tooth will again swing the lever 39 so as to rock the valve 11 to the position uncovering port 9, thereby permitting a fresh charge to pass from chamber 10 to chamber 8.

Compression of the charge entering chamber 10 1s obtained as follows :-()n the shaft 3 is secured an eccentric collar 46 which is embraced by the upper end of a rod 47, the lower end of which is pivoted. to the upper end of a bar 48, the lower end of lwhlch is secured to the upper side of a revent the engine running at more to raise the pawl to a position in which it4 piston 49 vertically reciprocative in a cylinder 50 secured to the forward side of casin 4. Connected to the lower part of the cy inder 50 on opposite sides thereof `are two

valve casin

51 and 52, each havlng an opening in 1ts u per end in whlch is secured a plug 53 disposed above apvalve opening in the casing controlled by a' check valve 54, the vertical stem of which 1s slidable in a hole provided therefor in the lower end of the adjacent lug 53. As the piston 49 ascends air is rawn from the atmos here into the valve caslng 51, the valve in said casing is lifted and the air passes into the cylinder 50 below the piston 49.

As the piston 49 descends the valve in casingA 51 closes and the valve 54 in casing 52 is raised by the air pressure, thus lprmittlng the air to ass from casing 52 y a conductor 56 into a storin or compression chamber 57 from which t e compressed air passes by a conductor 58 into a valve casing;

59. The valve casing 59 is provided with a valve opening 63, in which normall rests a valve 62, which is vertically guided 1n a hole 4provided in the lower end of a plug 61 which is secured in an opening in the upper end of the valve casing 59. The casing 59 is connected by a conductor 60 with the supplemental chamber 10. The valve 62 serves as a check valve to prevent the back passa e of iuid through the opening 63 into the c amber 57.

From the above description it will be seen that rotation of the piston 1 will cause air to be compressed and stored in the chamber 57 from which charges will pass through chamber 10 and port 9, and that these charges will mingle in the explosion chamber 8 with charges of fuel. The charges of mixed fuel and air will be successively exploded in chamber 8 and will successively pass into the cylinder 6.by the port 7, the outer end of which is preferably bifurcated and the branch 64 dis osed so that both branches of the port will simultaneously be op osite two blades of the piston 1.

Vhen the heat of the com ressed air admitted to chamber 8 is insu cient to cause ignition of the mixed fuel and air in said chamber the mixed air and fuel may be ignited by any other suitable means, as for instance, by a jump spark. To effect this latter mode of ignition a Awire 65 is connected to the upper end of an electrode 66 which is mounted in 'a block of insulation 67. secured in a metallic screw threaded plug 68 fitted in a vertical threaded opening extending through the casing 4 into the eX- plosion chamber 8. The inner end of the plug 68-is provided wlth an electrode 69, adjacent to but not touching the inner lower end of the electrode 66. A wire 70 has one endconnected to a U-shapled metallic spring 71, shownin Fig. 4, whic is mounted upon but insulated by insulation material 72 from a projection 73 on the front of the casing 4. On the free end of the spring 71 is mounted an adjustable screw 74 which extends through a hole in the spring and is secured thereto in the position to which itmay be adjusted, by a lock nut 75.

On the rod 22 is secured a contact plate 76 which isadapted to strike the u per end of the screw- 74 when the rod 22 descends.' By roperl adjusting the screw 74, as may be one w en the engine is running, the plate 76 may be' made to strike the screw 74 when the ports communicating with the explosion chamber 8 are all closed. Any suitable source of electric current may be employed to obtain a spark between the electrodes 66 and 69, the

wires

65 and 70 forming part of the circuit in which the current is generated. The circuit is completed between the contact plate 76 and plug 68 by the rod 22, lever 21, shaft 20 and casing 4.

If desired a portion of the fuel may be taken with the air into valve casing 51 by means of a tube 77, shown in Fi 4. I prefer, however, to introduce the fuel into the chamber 8 through a conductor 78, after the charge of air has been introduced into said chamber, and subsequently to the closing of the port 9 by the valve 11, and prior to the opening of the port 7. To accomplish this the conductor includes a valve casing 79 having mounted therein a rock valve 80 provided with a passage 86 extending upwardly through said valve. The valve 80 hasv secured to it a lever 81 by which the valve is rocked. The valve 80 is held normally in the closed position, shown in Figs. 4 and 11 by a coil spring 87 one end of which is secured to the lever 81, the other end being secured to a pin 88 secured to the conductor 78 above the valve casing 79.

A lever 89 is pivoted by a pin 90 to the forward side of the rod 40, and is adapted to have its lower end strike the lever 81 when the rod 40 is descending, thus rocking the valve 80 to the open position, and thereby permitting a. charge of oil to enter the chamber 8 through the conductor 78. The disposition of the parts is such that the lever 89 will not swing the lever 81 toa position opening the valve 80 until the valve 11 has closed the port 9. When the valve 11 has been swung by the lever 89 to close the port 9, after a charge of compressed air has entered chamber 8 through the port 9, the lever 89 will strike the lever 81 and open the valve 80, thus rmitting a charge of fuel or oil to enter c amber 8, where the charge mixes with the charge of compressed air and explodes before the valve l2 uncovers port 7. The heat of highlycompressed charge of air or the ectuical igniting means may be em loyed to ignite the mixed` fuel and air.

s soon as the proper charge of fuel has downward. In the path of movement of the claw arm 91 is a horizontal pin 92 disposed eccentrically toa rearwardly extending portion which is rotatively adjustable in the forward side of the caslng 4. The lever 89 has an arm 9 3 to which is secured one end of acoil spring 94 the other end of which is secured to the rod 40. The spring 94 normally v holds the lever 89 a inst a pm 96 secured to the rod 40, and 1n position to have the lower end of the lever 89 strike the lever 81.

After the charge of compressed air has been admitted'through the port 9 into chamber 8, the weight 41 forces the lever 89 to a position closing port 9. The rod 40 in moving downward causes the lever 89 to strike the lever 81, after the valve 11 has closed port 9. The charge of fuel having been admitted to chamber 8 through conductor 78, the continued downward movement of the rod 40 brings the claw arm 91 against the eccentrically mounted pin 92 which swings the lever 89 to a osltion in which the lever 81 will be release thereby permittin the spring 87 to close the valve 80 as be ore described. By rotating the eccentric pin 92, the position of the said pinmay be changed so as to vary the time at which the lever 81 is released from engagement with the lever 89, thus varying the amount of fuel admitted.

From the above it will be seen that charges of air and fuel are consecutively 'admitted into chamber 8 through the inlets 9 and 78 while the valve 12 closes port 7, the charge of fuel being admitted subsequent to the closin of the port 9 and prior to the opening o port 7. The mixed charges are then exploded, the

valves

11, 12 and 80 being all 1n the closed positions, after which, the valve 12 is swung to a position opening port 7 through which the charge escapes at high pressure into cylinders 6 and against the piston 1. By adjusting the screw 30 the degree the port 7 is uncovered may be varied, so as to ermit the exploded motive fluid to ass quie ly or less qulckly into the cylinder.

o prevent leakage around the shafts 2O and 33, each shaft is provided with a peripheral annular flange 79l which bears a ainst the inner wall of the chamber in w ich said shaft is located.

In Fig. 3 is shown a modified means for retractin the valve 12. In this form the lever 21 as pivoted to it the upper end of a rod 80 the lower end of which 1s pivoted to the lpiston 81 which is vertically reciproattesa cative in a cylinder 82 secured to the forward side of the casing 4, and provided with an open upper end and a closed lower end. An air outlet 83 is provided in the cylinder 82 below the limit of the stroke of piston 81. The weight of iston 81 swings the lever 21. When the va ve 12 is in the position shown 1n Fig. 3, closing port 7 the raised portion of the cam 26 supports the roller 25. As the cam rotates said roller drops4 into a recessed portion 84 on the cam, at which time, the valve 12 will swing so as to close ort 9, but not enough to open port 7. At thls time the plate 76 will strike the screw 74 thus completing the electric circuit on which completion a spark will ass between the electrodes 68 and 69, and) the motive fluid will be exploded in the chamber 8. Continued rotating;f of cam 26 will permit the roller to drop o recessed portion 84 of cam 26, and the ever 21 will be retracted by the spring 27 until the arm 29 strikes the screw 30. At this time the valve 12 will have closed portl 9 and opened port 7.

'In the modified form of cam shown in Fig. 10, the cam 85 is rovided with two raised portions disposed iametrically o posite each other. Two similarly locate recessed portions 84 are provided on the periphery of the cam. Upon ever revolution of the shaft 3, the valve 12 wil be' rocked to and fro twice. The valve 11 may also be rocked twice durin each rotation of the plston, thus permittlng two charges of motive fluid to be discharged into and exploded in the chamber 8 during one revolutlon of the piston. The power of the engine may thus be materially increased by providing the cam 85 having two raised portions for raising the roller 25. The cyllnder 6 and casing 4 is provided, as shown in Fig. 1 with a passage 86 for the escape of the used motive Huid. y
