Abstract

A reciprocating spinning piston engine or pump includes pistons 16 and orbiting crankshafts 7 which cooperate with an orbiting body 19 and a central crankshaft 1. The throw of the central crankshaft 1 being twice that of the orbiting crankshaft 7. It also contains wheels 20 which revolve around tracking 27 for levelling the orbiting body 19 and may also have a ball and socket (28, figs.12 & 13) in the orbiting body 19 to compensate for deviation in the rotation of the orbiting body 19. It operates such that the pistons 16 both spin and reciprocate within their cylinders and the engine provides enhanced torque. The orbiting crankshaft 7 operates on a plane 90 degrees apart from the plane of the central crankshaft 1. A connecting bar is used to keep the orbiting crankshafts synchronised and to prevent the piston and orbiting crankshaft from spinning in the same direction.

Description

Reciprocating Spinning Piston Engine.

This invention relates to a device which may be used as an engine or pump.The problem in a conventional engine is that it develops rotary power from friction.?his engine has been invented to solve the problem of side thrust and improving torque such that the force acting on the engine In mid-stroke is tangential.Its most distinctive feature is that it possesses spinning pistons that operate within a static engine casing.These pistons transfer power to a central crankshaft via orbiting crankshafts and an orbiting body.The orbiting body is mounted on the central crankshaft crankpin and houses the orbiting crankshafts which rotate on a plane that is 90 degrees different to the plane of the central crankshaft.The orbiting crankshafts therefore spin on the same.plane as the pistons but in opposing directions.

The throw of the orbiting crankshaft and the eccentricity of the piston crankpin housing is half that of the throw of the central crankshaft.The stroke length of the combined orbiting crankshaft and piston is 4 times the relevant eccentricities which matches the stroke depth of the central crankshaft.

There is a case for claiming that this is a rotary engine since each and every moving part rotates.

The invention will now be described by way of example and with reference to the accompanying drawings in which-Figure 1 shows a front perspective of the engine in mid-stroke. It is seen in cross-section with the central crankshaft 1 and wheels intact.

Operation of the reciprocating spinning piston engine.

The operation of the engine will be described with reference to drawings in figures 4-9.Figures 4,6 and 8 show a front perspective and figures 5,7 and 9 show an overhead perspective. The orbiting crankshaft 7 is indicated by shaded lines and rotation points by shaded spots.

In figures 4 and 5 the engine is at the top of the stroke.The mainshaft of the orbiting crankshafts 8 and their crankpins 13 are in line with the crankpins. 13 positioned toward the back of the engine.The piston 16 too is positioned with its crankpin housing 17 toward the back of the engine as both the crankpin 13 and the piston housing 17 are of the same eccentricity.

Pressure from the combustion stroke causes the central crankshaft 1 and the orbiting body 19 to turn until the positions shown in figures 6 and 7.At this point the central crankshaft crankpin 3 and orbiting body 19 has moved sideways by,CY The orbiting crankshaft crankpin 13 and piston housing 17 have moved transversely byi3T? The piston 16 has turned clockwise by 45 degrees and the crankpin of the orbiting crankshaft 13 has turned anticlockwise 45 degrees to match.The eccentricity of the orbiting crankshaft crankpin 13 to the mainshaft of the orbiting crankshaft 8 constitutes a further 4/F-5 leaving the total transverse movement of the mainshaft of the orbiting crankshaft 8 at,1373ffitlfaIn figures 8 and 9 the engine is in mid-stroke.The central crankshaft crankpin 3 and orbiting body 19 having moved sideways by 2 units while the total transverse movement is also 2 units being the sum of the eccentricity of the piston centre to the crankpin of the orbiting crankshaft 13 plus the eccentricity of the mainshaft of the orbiting crankshaft 8 to the crankpin of the orbiting crankshaft 13.

Components of the reciprocating spinning piston engine Central crankshaft-This is a short crankshaft with a mainshaft 2 at each end housed within Cie engine casing.Eccentric to that by 2 units and inward from the mainshafts is the crankpin 3 upon which the orbiting body 19 is mounted.Two bearings 5 are required to connect the crankpin 3 to the orbiting body 19.

Orbiting body-This is a generally flat body sufficient to contain the housings of the central crankshaft crankpin 6 and the housings of the orbiting crankshaft mainshafts 11 and the orbiting body roller shafts 22.0n its central axis are the housings of the central crankshaft crankpins 6 and outward from that and equidistant are the housings for the mainshafts of the orbiting crankshafts 11.These are holes bored vertically and at degrees to the plane of The central crankshaft 1 and are sufficient to hold the orbiting crankshaft mainshafts 8.Outward from that on the nearside are the orbiting body roller shafts 22 which project from the orbiting body 19 upon which wheels 20 are mounted which revolve on the same plane as the central crankshaft 1 around a tracking 27 which is a circular hole in the casing equal to the stroke depth plus the diameter of the wheel 20.The function of the wheels 20 is to help keep the orbiting body level at all stages of its rotation.

Ball and socket-This is an optional extra as an adaption to the basic orbiting body 19.In this adaption part of the orbiting body 19Aremoved to provide a socket which is fitted with a ball which surrounds the orbiting crankshaft mainshaft rim 9 and the requisite thrust bearing 10.In this* way deviation in the rotation of the orbiting body can be compensated for.

Orbiting crankshafts-Are subject to a downward and upward pressure so are fairly narrow in width.TheY differ from the central crankshaft 1 in that the mainshafts 8 are in the middle portion of the crankshaft where it rotates within the thrust bearing housing 11 and the crankpins 13 rotate within the pistons 16.The eccentricity of the mainshaft 8 to the crankpin 13 is 1 unit or half the throw of the central crankshaft.The orbiting crankshafts comprise of the following-At each end is the crankpin rim 14 upon which the piston thrust bearing 15 is housed.Onthe other side of the rim is a flange designed to hold the piston in place.Upward and downward from the rims is the crankpin rod 13.This extends the length of the piston.Inward from the crankpins 13 at one end is a cam 12 which at its central point is 2 units from the mainshaft 8 and in the same direction as the crankpin 13.It is the function of these cams to drive the connecting bar 23 in a front to back rotary action.Inward from each end is the mainshaft 8 and further inward is the mainshaft rim 9 which contact the thrust bearings 10 that are contained within the housing 11.

Pistons-There are 4 of these in the engine shown.They are basically long cylinders bored eccentrically at 1 unit or half the throw of the central crankshaft.They envelop the crankpin rods113 and rim 9 of the orbiting crankshaft 7.They also house the piston thrust bearing 13.These pistons rotate as they reciprocate.

Connecting bar-Thisconnects the cams 12 of the orbiting crankshaft 7 and extend at each end to contact walls in the engine.Their action is rotary against these walls.They are necessary partly to synchronise the action of the 2 orbiting crankshafts 7 and partly to ensure that the piston 16 and orbiting crankshaft 7 do not rotate in unison when at the top or bottom of the stroke.

Wheels-these are simply rollers set upon bearings 21 to keep the orbiting body level while rotating.

Bearings-There are a total of 6 roller bearings and 8 thrust bearings.These bearings are indicated in the drawings by black shaded areas.It should be noted that the engine may perform well without bearings in the pistons and that this is an alternative.
