To all whom it may concern:

Be it known that I, ELMER E. E. SU'rrmN, of Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Explosive-Engines; and I hereby declare that the followmg is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part ofthis specification. I I

This inventlon is a novel improvement in explosive engines of the rotary ty e in which the gases are ignited in 'an exp osionchamber, or chambers, from which they are admitted into the working chamber wherein is preferably mounted a. rotor, or turbine wheel, to which'motion is imparted by such gases and after the latter have been used in said chamber the may be exhausted to the atmosphere or'ot erw1se-utilized, The principal featureof'my invention is a working chamber, and means for producing and conducting explosive gases from such explosion chamber to the working chamber.

Subordinate features are (1) novel means whereby the gases may be caused to drive the rotor in either direction desired; (2) novel means for operating the cylinders in (3) novel means for operating the valves; 4) and the general novel arrangement an construction of the an no as a whole.

I wi I explain the invention in detail with reference to the accompanying drawings. which illustrate one form of the'engine embodying the invention and which in connection with the following description will enable any one skilled and use thesame.

In the drawings Figure 1 is aplan view engine. Fi 2 is atrans- Fig. 3 is a cross section on the dotted lines 2829 of Fig;"'2.- Fig. 4 is a plan view of one-half of the outer shell 15 of-the rotor.

an enlarged perspective view of one corner, or part of the engine showing the general operative arrangement of the c linders and controlling valves, parts being roken away for clearness of illustration.

As shown the engine comprises a main frame or casting A which is shown as approximately rectangular and has a central cylindric working chamber which may be c osed at its ends by removable plates D are bearings for a main shaft a which extends axially through said chamber; within this working chamber rigidly secured to the axle in any suitable way is a rotor 21 which may consist of a -cyl1ndric' body provided with radially disposed transverse Iades 13 forming pockets 3 into which the propelling gases are injected as hereinafter described. The plates D, F' 3, are preferably made hollow and provided with water chambers 17 to which water can be supplied through openings 71., Figs. 3 and 10, by any suitable pipe connection (not shown); and the plates are provided with apertures it near their axes through which water can pass through apertures 18-in the sides of the rotor 21'intothe water chamber 2 in said rotor, see Figs. 2 and' 3-; and the water can escape at the opposite sideof the rotor through the apertures 18 and h to the outlet 75. at the opposite side of the casing; thus a circulation of water can be maintalned around the working chamber and within and through the rotor therein.

As shown the rotor is impelled byexplosive gases which are supplied .thereto through suitable valve ports from the explosion chambers, shown,such exploding chambers (34, 35, 36 and 37 being in cylinders B, B, B, B, attached to the frame' The exploding chambers and their valve connectionsrand parts are substantially alike, and preferably the exploding chambers are cylindri-c in cross, section, and in each exploding chamber is a cylinder piston which is operated by the gases as hereinafter described.-

One end of each cylinder communicates by a port 5 with an adjacent valve chamber in the casing, in which 15 a rocking valve M and the other end of each cylinder communicates with the adjacent valve chamber by As shown there'is one valve chamber adjacent the adjacent ends of each pair of cylinders, or in. other words there are four valves M for four cylinders;

each valve M is provided with two ports 6, I

6, either of which may be brought into communication with either port 5 or' 5; and each valve chamber communicates with the 5 periphery of the working chamber by ports 7 and 7,'port 7 leading to .thefleft and ports 7 to the right. The ports in valves M f are so proportioned that when ports 6 are in communication with ports SM 5, the gases be admitted from the cylinders through the valve chambers to the ports 7 and the rotor will thus be turned to the left, Fig. 2. But if the valves be shifted so that the ports 6 register with the ports 5 or 5' then ports 7 will be closed and the gases will be admitted through the ports 7 to the working-chamber, and the rotor will be driven to v the right. Thus by properly setting the valves M therotor can be caused to turn to the right, or to the left, The mechanism for adjusting the valves to, reverse the engine is hereinafter described.

Adjacent each valve M and intermediate the outer ends of each pair of adjacent cylinders, is a rock shaft H which is mounted in a bracketI attached to'the frame A. On

this shaft is a crank arm G which is piv-" otally connected by' loose pivots to rods F,

F. Rod F enters the head of one of the adjacent cylinders and rod F enters the head of the other adjacent cylinder (see Fig.

10) and these rods project sufiiciently into I the, cylinder to be struck by the pistons therein when the piston moves-to that end of the cylinder, and when either rod is struck by a piston it will impart a rocking motion to the shaft H.

Referring to Figs. 2 and 10, if the piston a in chamber 36 be driven to the left hand 40 end of the upper cylinder B the piston t will strike the rod F and force it to the left,

thereby rocking shaft H to the left, and

- causing the rod F to be projected farther into the chamber 35. When piston 4: in

chamber 35 is driven toward rod F it will force the latter outward and shaft H will be rocked to the right and rod F will .be

- again projected into the left hand end of chamberBG. The pistons in the chambers 36 and 35 are operated in alternation; so

that the shafts H are rocked first one'way and then the other; and the same is trueof each rock shaft H of the engine shown.

, On each shaft H is a'crank disk'Nwhich may be connected by atoggle link QR to a slotted head M on the end of the adjacent valve M As shown the link R is adjustably connected (as by a pin 70 and slot Z) to the 'head M of the valve M This slot 1 in the head M of the valve M is for the purpose of adjusting the valve so that the ports 6-6 will register with the ports 5-5'. The slot I only acts as the crank-of the valve lid and does not necessarily ex tend. across the center of valve M it is not of the ports and 5' at the proper times.

used in any way for the purpose of revers ing the rotor, but is to be used in case some 5-5 should be a little closer together or farther apart than the others, the link R could then be adjusted in the slot Z so as to give the valve more or less throw as the case should demand. The reversing of the rotor is accomplished entirely by throwing the links Q, R, to the position indicated by the dotted lines, this brings the port 6 into play instead of port 6. The connections of links R to valves l 2 may be simultaneously shifted to reverse the engine, by means of 'anannulus u, at one side of the engine, to which annulus are pivotally connected links 5 which are are connected also to the pivot-s connecting links-Q R. The annulus may be rotatahly supported on lugs attached tothe face of the engine, and as shown the annulus is provided with guide slots 0 engaging such lugs and retained in position on the lugs by plates m, Fig. 10. The annulus may be rotatably adjusted by means of a hand lever 2, attached thereto at y, and when the annulus is in the position shown in full lines Fig. 10 the valves M will be shifted so as to always direct the gases from the exploding chambers through the ports 7 'to the working chamber within the annulus. When the'annulus is shifted to the position indicated by dotted lines 2', Fig. 10, the

valves M will then direct the gases through ports 7 to the working chamber. The

cranks and links Q-R are the means for *rocking' the valves M and the shafts H are rocked back and forth as described, by the pistons so as to open and close ports 5 The working chamber is provided with four exhaust port-s 8, one of which is located intermediate each pair of adjacent ports 7 7 so that the gases after operating the rotor can escape "through-ports 8 to any suitable exhaust pipe, (not shown).

Explosive gases are admitted into each end of each exploding chamber through pipes Cr, 1'", pipes a" being adjacent the rods F and pipes 0" adjacent rods F the. adjacent pipes r, r connect at different points with a valve chamber ,L which may be mounted on the bracket I adjacent the arm G; and in each casing is a valve K having a radial port 20 which communicates at center of thecasing with a pipe 22, (see Figs. 7- and 8), The valve K is connected to the adjacent shaft H so as to be rocked thereby simultaneously with the shifting of the related valve M ternately deliver the pipes, r, 7". from a reservoir 41, Fig. 1, the supply from which may be regulated by a main controlling valve 42. v

The explosive gases are the gas from pipe 22 to supplied to the Gas is supplied to pipe 22 and valve K will alreservoir 41 by means of a pum d whiclf communicates with a pipe f lea mg from a suitable carbureter, (not shown, .and the explosive gases are drawn by t e pump communicating water chambers or passages through pipe f and. forced through the pipe e into the reservoir 41. The. pump (Z may be operated in any suitable manner. As shown in Fig. 1 the pump piston rod 0 is connected to a crank pin one, disk 6' whichis rotatably mounted on a stud e and is fast to a pinion e which meshes with a second pinion e on a stud, and pinion e in turn meshes with a pinion e on shaft a, so that for ca h rotation of shaft a the pump may be reciprocated a number of times. In Fig. 10 the pump piston rod 0 is shown as operated by an eccentric b on shaft a, so that it will be reciprocatcd once for each rotation of shaft a.

I do not confine myself to four explosive chambers as shown in the drawings, as there may be'two, three, four, or more, as may be necessary to insure the proper operation of the valves, and obtain the desired power; and said explosive chambers ma be of any shape best adapted .to the size 0 motor and to the use it is to be put. Also I do not wish to confine myself to any particular means for operating the pump; and the res ervoir 41 might be supplied with explosive gases in any suitable way. The explosive gases admitted into the chambers 34, 35, 36, 37, may be ignited at the proper time by any suitable means; as shown I have indicated an electrical spark plug p in each explosion bhamber; and these spark plugs may be connected in any suitable way to any convenient source of electricity.

As shown each spark plug 2) is electrically connected by a conductor a to contacts 0 be side the adjacent disks J; opposite each contact 0 is another contact 0' which may be connected to a conductor m. The conductorsf n and m may be connected with opposite poles of any suitable source of electrical energy. The conductors n, m, are similarly connected to contacts 0, 0 arranged beside the diskJ at each end of each cylinder. On each disk J is a contact piece N which as the disk is rocked, enters between the opposed contacts ,0, 0 and closes the circuit therebetween, thereby transmitting current to the related spark plug and causing the ignition of the gases at the proper times.

The electrical connections are diagrammatically indicated in Fig. 6, but such connections constitute no part of the present invention, and may be varied according to the nature of the plugs used, or the preference of the electrician, therefore it is unnecessary to give a more detailed explanation thereof herein.

27, 27 are check valves placed in the gas supply pipes r, 1" to prevent gas being forced back into the'main supply pipe 22 'sure of gas in the reservoir;

' at the t' e of ignition in the explosion chamberg: and to relieve the pressure on the valves nd to help form the cushion 9.

Preferably the casing A; is provided with withdrawn at y or any suitable point.

Operation: The compressed gas supplied from the reservoir 41 will force the pistons alternately from one end of the explosion chamber to the other when the throttle 42 is opened. Assuming that the gas has entered chamber .36, Fig. 2, at 5 under pressure from reservoir 41, it will push the piston 4: to the left, and such piston comes in contact with and forces the'rod F to the left, operating the valve K, Fig. 10 attached to the related shaft H, and allowing the gas to enter the cylinder at 5; this will check the piston i,but'there is movement enough of the rod F before the piston 4 is entirely stopped to also actuate the disk J, Fig. 10,

and make the electrical connection at N,

which explodes the gas in the cylinder 36, closing the port 5 and opening the port 5,- this action would necessarily retainthe explosive gas in chamber 36,.as the port 5*has to be opened by the like action of piston 4 which will be moved in chamber 37 and actuate the related valve 6 so as to put port 5 in communication with port 7. The several pistons all operate at about the same rate of speed and the explosions in the several chambers will necessarily QQcur in successio-n. After each piston has' traveled in one direction it will be {moved back in like manner and operate the other valve, the rotor. turning in the same direction. The explo sive gases remain in the cylinders until the ports 7 or 7 are opened as described. In initially starting the motor the pump d can be operated by hand (as by means of a crank (not shown) detachably attached to shaft a) until a suflicient supply of gas is compressed into the reservoir 41; or the reservoir 41 can be filled \vitlrcompressed gas in any convenient manner. The motor will be self starting so long as there is a suflicient pres- Assuming that there is a proper supply of compressed gas in reservoir 4:1, all that is necessary to start themotor is to open the throttle in the main gas supply pipe; this allows the gas (for example) to enter the explosion chamber 34 (Fig. 2) and force the piston head therein toward the right hand end of such explosion chamber where it comes into contact with the rod F, and forces it and the crank G to the right, thereby rocking the shaft H and the connected valve K so that the port 20 the opposite end (Fig; 8) is Opened, allowing gas to flow through pipe 1" into that end of the explosion chamber and form a cushion between the pistonand end of chamber such as shown at 9,chamber 36, Fig. 2. Such cushion prevents the piston head when the gas is exploded in the opposite end of the chamber, which explosion occurs as the contact '11 on the disk J, operated by said shaft H in its movement to, the right, closes the circuit between the contacts 0, 0,

thus producing a spark at plug p, ig. 6)

and an explosion in the chamber '34:, Fig. 2. The exploded gas remains in the chamber 34: until the piston 4 in chamber 351has forced the rod F therein down, thus operating the adjacent rock shaft and valve M so that the port 5' in chamber 34L is opened to allow the exploded gas to pass from chamber 34: to the working chamber and operate the rotor in the direction indicated by the arrow and finally escape through the exhaust "ports 8. This operation is repeated in succession in the four explosion chambers forcing'the pis-- tons in the directions rows.

\Vhen the second piston has reached of its explosion chamber and the valve i? at that point has been operated, the exploded gas in the first explo sion chamber begins to flow through the ports; and the pressure is reduced in that end of such explosion chamber until the gas entering from the reservoir moves the piston in the opposite direction, thus exhausting all of the previously'explode'd gas. The pistons in each explosion chamber are thus operated and operate the rods F, F, thus successively shifting the valves M and allowing the ex- .ploded gases to pass through the ports 5, 6,

7, (Fig. 2) to the Working chamber, and operate the'rotor in the same direction. The

. explosions in the several chambers will necessarily follow each other in succession, as each is dependent upon the piston in the next following chamber tocpen the valve M and allow the exploded gases to escape to the rotor; thus by the time the fourth piston has accomplished the operation of the valves the becomes automatic.

' To reverse first pistonis traveling in the opposite direction and the whole mechanism thereby When the rotorrotates in the direction indicated by the'arrows the ports 6 of the valves M oscillate between ports 5 and 5 and the ports 7 remain open. the rotor the lever Z is thrown to the position indicated in dotted lines at e, u, and the connecting rods R, to .the

dotted positions Q, B, thus shifting the valves M closing ports 6 and causing the ports 6 to oscillate bet-ween ports 5, and5; thereby closing the ports 7, and opening the ports 7; thus driving the rotor in a direction opposite to the arrows.
