SIDNEY H. IVERY, OF ST. LOUIS, MISSOURI.

ROTARY EXPLOSIV'E-ENGINE.

To all whom t may concern.'

Be it known that I, SIDNEY H. IvEBY, cit1- zen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Rotary Explosive-Engines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

.My invention has relation to improvements in rotary-explosive. engines; and it consists in the novel details of construction more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure l is a combined top plan, and horizontal section of theengine on the line l-l of Fig. 2; Fig. 2 1s a vertical section on the line 2--2 of Fig. l; Fig. 3 is a vertical sectional detail on t-he line 3-3 of Fig. l taken through the exhaust valve of the cylinder; Fig. 4 is a. vertical section on the radial line 4*-4 Fig. l, (certain parts being omitted) Fig. 5 is an outer end view of two of the revolving cyl inders; Fig. 6 is a top plan of a portion of the ring or flange for guiding the valvecontrolling bars; Fig. 7 .is an elevation of Fig. 6, with wall below the ring in section; Fig. S is an edge and sectional view of the exhaust-valve and wiper carried thereby; Fig. 9 is a plan of the exhaust valve; Fig. 10 is a plan of the cam traversed by the valve-controlling bars; Fig. 11 is a side view of the cam with part in section; and Fig. 12 is a diagrammatic view showing the successive positions of the exhaust-valve relatively to the spark-plug for a single revolution of the cylinder around the cam.

The object of my invention is to construct a rotary explosive engine employing the turbine principle o-f propulsion, water or other liquid being utilized in conjunction with the explosive mixture to effect the rotation.

The employment of water or other liquid dispenses with the necessity of employing mechanical pistons, thereby not only reducing the cost of construction, but at the same time serving as a means of keeping the working parts cool or at least preventing the overheating thereof.

further object is to lconstruct an engine with minimum number of parts; one in which the several parts work positivelyand with certainty, maintaining a perfect Specification of Letters Patent.

The invention presents further and other features of construction better apparent from a detailed description thereof, which is as follows Referring to the drawings, S represents a vertical rotatable shaft mounted in a stepbearing B, resting on timbers T, the upper end of the shaft terminating in a hollow portion S from the base of which radiate the ports a, a, said ports being in communication with the chamber c ofa hollow casting or member l keyed to, and rotating with the shaft. The upper terminal of the 'shaft has its bearing in the hub 2 of a spider 3 the outer ends of whose arms are bolted to the outside of the vertical walls of a liquid container or pan 4 loosely surrounding the shaft, the latter passing freely through the bottom hub 2 of the pan as shown (Fig. 2). The pan rests on the bearing B and is in addition secured xedly by standards 5 bolted to the timbers T. Cast integrally with the casting or rotatable member l are a series of cylinders 6, whoseJ several axes radiate from the axis of the shaft S as shown. The outer head of each cylinder is provided with a liquid discharge port 7 controlled by a hinge-valve 8 which is normally held closed by a flexed springt) (Fig. l). Located at the outer end of the side of each cylinder is a port l0 controlled by. a two-way rotatable valve V, the same valve likewise controlling the outer liquid discharge or waste port 11 located between each pair of cylinders and in addition controlling the discharges from the upper end or goose-neck of the curved conduit l2 cast with the member 1., the intake end of each conduit dipping into the liquid in the pan 4 at a point near the axis of the shaft (or axis of rotation of the member l) the level of the liquid being indicated by the dotted The conduits 12 are so cast that they curve in a horizontal plane from their intake to the discharge end, the raised discharge or gooseneck end then rising between two cylinders and coming opposite the port of the two-way valve V.

'Communicating with the upper hollow portion S of the shaft S is the base of any conventional carbureter i3 for supplying the explosive mixture to the chamber c of the rotatable member l, the gas being admitted into the cylinders 6 by a check-valve 14 the stem 15 of which is guided between two rods 16, 16, which at the same timeserve as an abutment for one end of the controlling spring 17, the opposite end being secured to the stem. The latter is guided in the passage-way d provided for it, by a cross-pin 18 which bears against the walls of the passage-way. To limit the inward movement of the valve l14 `-(that is to say a movement toward the cylinder) I provide a shi-eld lor guard in the form of a disk 19 which is screwed into thel center ring or hub 20 of a spider whose arms 21 are secured in any mechanical manner to the inner head of the cylinder. l

Carried by each cylinder is a spark-plug 22 of conventional design, the several plugs being connectedv by a .conducting wire lw, a common feed wire w supplying theculfrent, the inner end of the wire w.being in electric connection 4with a wiper 23 whose free end traverses a collector disk 24 loosely enveloping the shaft S and properly insulated, the current being supplied to the collector-.by the line wire W leading from any source of electrical energy. The wiring is not here claimed nor dwelt upon as that is Within the skill of the mechanic. Keyed to the shaft S below the collector disk 24 is a gear wheel 25 which meshes with the larger section 26 of a double gear mounted about a stud s carried by the spider frame 3, (Fig. 2), the smaller gear section 26 in turn meshing with a gear 27 passed loosely about 'the shaft S (so as to turn independent thereof),the gear 27 being larger' than the gear 25, so that a slower' rate of rotation will be participated in bythe gear 27 than is imparted to the gear 25 keyed to the shaft. We may for convenience assume that the gear 25 makes .thirty revolutions to twenty-nine (or fewer) imparted to the gear 27, the reducing gear shown being availed of for a purpose presently to appear. The body of the loose gea-r 27 is provided with sockets for the reception of the pins m, m, (Fig. 11) of a cam 28 passed loosely over the shaft section 4S and shouldered on the solid v section S (Fig. 2), the cam necessarily participating in the rotations imparted to the gear 27. Cast with the member 1 and surrounding the cam is' a fla-nge or rim 29 the top of which is surmounted by a circular band or ring 30 provided with alternatelyv low and high inverted- U-shaped bends t, t', respectively, the higher bends t spanning the projections or lugs 31 distributed along thez'top ofthe flange 29,

posed. valve-controlling bars32, .whose vinner-converging terminals are provided with c largenumber'of these bars (32) they could.-

valves V being long and short owing to the i A The ,respective zloops t,.t form guides forjthe radially disnot conveniently be disposed in the same plane, so for convenience they are disposed in pairs, the lower bar of each pair passing through a guide-loop t and resting on the upper edge of the flange or ring 29, the other bar resting on the projection 31 and passing through the loop/t as quite obviousl from the drawing. For the same reason the height of the cam surface is sufficient to accommodate the rollers r necessarily disposed v 1n superposed planes.

y Each bar 32 is provided with a coiled spring-33 one end of which bears against the bar guide or band 30, 'the opposite end of the spring being se# cured to the bar (Fig. 1). The free outer l end of each bar 32 is provided with a racksection 32 which engages a pinion 34 (partiallyI toothed) carried by the stem of the rock-valve V, (the stems of the successive disposition of the bars 32 as'previously explained), the said bar being additionally provided with spring-controlled pawls 35, 36 adapted with successive strokes of the bar to engage a tooth and impart a partial rotation to the outer terminal ratchet disk 37 carried at the outer end of the stem 38 (the stems being alternately long and short toreach the successive bars for reasons previously explained) of the rotatable exhaust diskvalve 39, the latter being provided with an opening 40 to register at the proper time with the gas-exhaust port 41 from the cylinder. The edge of the-valve 39 carries a wiper 42 which at the proper time wipes' against the finger 43 leading from the sparkplug 22, thus drawing a spark and exploding the gas mixture in the cylinder. The contents expelled by the explosion discharges through the port 7 more or less tangentially, impinging against a series of ribbed abutments 44 cast at the proper an- -I gle along the inner face of the vertical wall of the pan.or container' 4, the contents so discharged against the abutments flowing back into the container 4, the member and shaft S rotating in the direction as shown by the curved peripheral arrow (Fig. 1), the shaft S' at points beyond the bearing B, being adapted to be coupled toI any suitable machinery intended to be driven.

The operation lofthe engine is substantially as follows Since the cam 28 has a relatively slower rotation than the shaft S and the member 1, we may for purposes of explaining the operation, assume that the cam 'is at rest. Let us assume for convenience (taking any cylinder' 6 of the series as anyvexample,v since they all act alike) that a-cylinder ha'svreached aiposition.where it has brought its particular-bar32 to that: portion ofthe camsurface"wherethe bar had turned the .valveY to. a-iaosition' so asto establish communication between the conduit12 and -theport`- 10 (Figi-11).. The centrifugal action yof the moving mass (the part 1, cylinders 6, and conduits 12 rotating as a unit) drafts the water (or other liquid) from the container 4 through the conduit 12 the liquid discharging into the cylinder through the passage-way of the valve V. The liquid thus entering compresses the charge of gas previously admitted (as subsequently to be explained) and as the mass continues to rot-ate, the bar 32 will gradually ride up the cam, forcing the bar outwardly so as now to close the valve V altogether (bottom Fig. 1). In this outward pushing of the bar 32, the pawl 35 there-of has rotated the valve 39 to closed position (bottom of diagrammatic view Fig..

12) and caused the wiper 42 to rub the iinger 43 of the spark-plug, thus exploding the gas, the explosion expelling the liquid (and some of the spent gases) through the port 7 past the gate-valve 8, against the fixed abutments 44, (and against t-he vertical wall of the pan 4 which likewise serves as an abutment), the-expulsion of the water and gases as described driving the mass as indicated by the curved arrow in Fig. 1, causing the cylinder 6 to thus revolve about the axis of the shaft S. The expulsion can continue while the roller end of the bar 32 is traversing the lower concentric curvature of the cam (Fig. 1), after which the bary will drop (or advance towardthe aXis of the shaft as clearly obvious from the shape of the cam in Fig. 1) and again rock the valve V to open communication between the conduit 12 and cylinder, the valve-8 having by this time closed, and the valve 39 having been turned by the pawl 36 (the pawls 35, 36, acting alternately but always rotating or advancing the gas-exhaust valve 39 in the same direction) to open position as shown at the left in Fig. 12 where the ports 40 and 41 are in register. The liquid is now again free to enter the cylinder under centrifugal action of the rotating mass, thel spent gases from the previous explosion .being free to escape through the open port 41. This continues while the bar 32 istraversing the left-hand concentric portion of the cam (Fig. l) after which the bar suddenly rises and rocks the valve V to the position shown at the right hand upper end in Fig. 1, thereby establishing communica-tion between the cylinder and the waste port 11, thus allowing the water (or other liquid) to be expelled from the cylinder back intO the-pan 4; and as the liquid is thus Vexpelled into the pan 4 from the cylinder 6 (in which expulsion centrifugal force plays an important part), the'mixture of gas flows into the cylinder to take the place of the expelled liquid, the gas flowing into the cylinberl c, thence through passage al, past the Ica-m surface. evaporation, the same liquid may be used over and over, and as a liquid it has the check-valve 14 (which is unseated) as obvious from the drawings.

As the mass revolves the valve V remains in the last position referred to while the bar 32 is traversing the upper concentric portion of the cam (Fig. 1) after which it again suddenly drops rocking the valve V to the first position described, that is to say opening communication between the cylinder 6 and conduit 12, when liquid is again free to enter the cylinder and compress the gas charge ready for the next explosion, thus completing the cycle. For a given cycle, the bar 32 makes two strokes inward and two outward, the pawls 35, 36 taking turns in imparting a rotary advance to the exhaust Valve 39, said valve uncovering the port 41 once only for each cycle, and that is to allow the spent gases to escape to make room for the liquid, as best shown in diagram in Fig. 12, in which the relative positions of the ports 40, 41, for a given cycle may be followed. The liquid entering the cylinder thus acts. as a piston of a four- -cycle engine, the liquid first entering the .being expelled from the cylinder to admit a fresh charge of gas, then entering the cylinder to compress this charge, then being expelled from the cylinder upon the sparking and explosion, the explosion imparting rotation to the mass (or revolution to the several cylinders) about the axis of the shaft S. Of course, each valve-controlling bar 32 is actuated outwardly by the cam 28, and inwardly 'by the spring 33 which causes the roller end of the bar to constantly hug the 1t is obvious that, barring advantage in that it keeps the parts cool.

By having a large number of cylinders, we may secure a corresponding number of impulses; and by properly regulating the dierential inthe number of rotations in a unit of time between the shaft S and the cam 28, the frequency of the cycles and impulses may be regulated. ,The reducing gear (25, 26, 26', 27) may be changed to suit working conditions, and hence any desired speed may be imparted to the shaft S, depending on the reduction in speed assigned to the cam. Obviously it is by reason of the gain in speed by the member 1 over that of 4the cam 28 which permits the bars 32 tol traverse the cam and control the valves V and 39.
