PATENT OFFICE DIC., A CORPORATION 0l' DELAWARE ENGINE Application med December 5, 1828. Serial No. 828,845.

This invention relates to an improved engine, which may be applied to the class of internal combustion engines and also steam en ines or outside the class of prime movers it 1s adapted for the construction of pumps.

An object of the invention is to prov1de an engine in which the number of parts is reduced to the minimum thereby decreasing the chances of accidental stalling of the enne. This makes it a highly desirable engine or aircraft.

Another object of the invention is to provide a cooling system of simple construction which insures an even proper temperature for the parts of the engine.

Another object of the invention is to utilize the piston, which is in the 'form of a wobblep'late, for keeping the inside of the cylinder clear of carbon and to eliminate uneven wear on the cylinder walls.

The invention is' illustrated in the accompanying drawings in which Figure is a section of an engine embodying m mvention. Figure 2 is a section of a modified f orm and Figure 3 is a section of another modified form.

The invention is designed to employ the re quired number of units to develop the required power, each unit comprislng a cylmder and a wobble-plate is confined in the cylinder so that its periphery passes through a fixed channel at one point in the cylinder. This causes the wobble-plate to move longitudinally except at this point and either moves on its shaft or the shaft is mounted tol move longitudinally to thek desired extent.

In the construction of the engine the usual form of cylinder is one with inclined ends that are at opposed angles and are thus in planes that converge. l

The wobblelate is of a depth to iit in the narrow part o the cylinder and when rot-ated passes throu h this narrow part, the portion of the wob le-plate not in this part being free to travel a limited longitudinal path determined by the pitch or angle of the wobble-plate.

In Fi has the inclined ends 11 and 12, these ends being in planes that converge and I show a gure 1 I show the cylinder 10 which' second cylinder 13 which has similar ends 14: and 15. The construction provides

narrow portions

16 and 17 of the respective c linders.

The cylinders are each provide with a wobble plate 18 which is proportioned to fit approximatel inthe narrow portions of their respective cy inders. As the wobble plates rotate they. pass through these narrow p0rtions and also move longitudinally in the cylinders. The shaft 19 is secured to the cylinders and moves with them. It slides in the bearings 20. In this particular construction the outer ends ofthe cylinders are the chambers which act as the propelling or explosionV chambers according to whether it is a steam or internal combustion engine. I show a spark plug 21 to indicate such explosion end of a cylinder.

The shaft causes the cylinders to move in unison and it is shown as keyed at 22 to the sprocket or gear 23 which is coupled to the mechanism to be driven. l

In each cylinder I show an exhaust port 24, an inlet port 25 and ahy-pass 26, all these disposed to be opened .and closed by the wobble-plate in each cylinder.

The engine shown in Figure l is in position for explosion of a mixture in the end l1 of the left hand unit or cylinder. -This will force the wobble plate to the other end of the cylinder and rotate it a one-half turn, this compresses the mixture on the other side of the wobble-plate and it is propelled through the byjpass 26 as the openin s 27 and 28 come in register with the two en s of the by-pass.

The opening 28 is a slit and the by-pass is Vformed to become broad and flat at its outlet -each as a two-cycle unit and the co-operation makes for a continuous smooth motion of the shaft 19.

The holes 34come in line or re 'ster with the holes 35 at the same time an allow oil to ass out by centrifugal force into the chamber 1. This forces an intermittent flow of fluid which is preferably oil and the o1l passes out at 32'l and is then again brought back to 32 by any form of return means. This o1l 1s wiped along the inside wall of the cylinder by the wobble plate, as the hole 34 passes along in a helical ath and this keeps the inside wall of the cyliner properly lubricated. The deosits of carbon on the inside wall of the cylinder are removed, as they form, by the edges of the wobble-plate.

These edges are more efficient when they are bevelled or pointed as at 36.

In the form of engine shown in Figure 2 the. shaft 19 is secured against longitudinal move-A ment and the wobble plates are arranged to rotate the shaft but they slide on it and the feather 37 slides in the key-way 38 in 'the shaft. In this construction the two cylinders vare arranged with the narrow part of one adjacent the wide part of the other to make a more compact structure.

In' Figure 3, I show four units and each one acts to co-operate with the others to form a four-cycle engine. Each one rotates effectively as a driving unit for 120 degrees of rotation so thatl they overlap in propulsion, thus making a smooth running mechanism. In this figure the left-hand unit i's in the position just prior to explosion and thus at the beginning of its power stroke. The second cylinder has. just :finished its power stroke and fened the exhaust port 39. Thethird cylin er is in its compression stroke and the fourth cylinder is in its suction or intake position.

The

shafts

40 and 41 are each slidable in the sleeve 42 which is held against any movement longitudinally by the flange 43 and the nuts 44 but rotates in the'bearing 45.

An engine provided with a wobble-plate rotating and also sliding in a cylinder eliminates uneven forces or side mot-ions and therefore excess wear on the shaft and the cylinder walls. The absence of valves and pushrods, cam-shafts and other extra parts eliminates the chances of these parts becoming disarranged or ineffective and in this respect this engine is particularly adapted for air-craft purposes.

An engine comprising a cylinder, a wobble plate rotatable in the cylinder and caaasasoi able of longitudinal movement, ,the cylinder fiaving ports to be successively opened and closed by the said rotatable and longitudinally movable wobble-plate whereby fluid can be compressed between the'end of the cyl- Vinder and the wobble-plate.

2. An engine comprising acylinder having a short si e, a wobble plate fitting in the cy1inder, the cylinder having inclined ends, and a stop at the short side of the cylinder against which the plate is adapted to bear inits rotation, the cylinder having ports for admission and exhaust of fluids and disposed so as `to -be opened and closedin proper sequence by the plate in its movement and thereby control the admission and release of fluid in the cylinder.
