Bessler - Rod -Wheel

Internal rod system
At chapter Bessler-wheel above, as an essential possibility for reconstruction of Bessler-wheel a concept with rotor gear wheels was suggested. Most of known Bessler-reconstructions however are based on systems of lever arms, but none of is known to use an external mechanism of pendulums. That´s why here a solution is presented, using external pendulum and internal a system uing but rods.

Basis
Masse thereby must be fixed or beared anywhere at Bessler-wheel and secondly at a central pendulum wheel. Distance between any point at Bessler-wheel and a point at pendulum wheel will differ while turning of system. This variable length could be managed by a rod telscopable, or it must be installed two rods, joint by a bearing, or even several rods with several bearings (might be like a trapez or parallogams, might be not symmetric). Here at first a system with only two rods shall be concidered, both joint by one bearing.

Thus here a system will be assumed some kind analog to external pendulum mechanism described at earlier chapter. So, this pendulum mechanism outside Bessler-wheel by itself, here won´t be described or shown once more.

Basic concept
At picture EVBER 11 basic principle is shown. Around system axis (SA) moveable shall be that central control-wheel. In order to differ this wheel from pendulum wheels above, this central wheel here will be called swivel-wheel (SR, German Schwenkrad). At this swivel-wheel a bearing (SG, German Schwenkgelenk) is installed, around which a swivel-rod (SH, German Schwenkhebel) may turn. Marked positions of this swivel-bearing resp. radius at the swivel-wheel do show a range of 90 degrees, maximum swinging ahead and back of this control unit.

Bessler-wheel (BR, here but a sector is marked by dotted circle) will serve again as rotor arm. Here however, no round turning rotor shall be used (oppositie to wheel-concept above). Nevertheless, at Bessler-wheel here, also a bearing will be installel, called rotor-bearing (RG, German Rotorgelenk). Swivable around this bearing a rotor-rod (RH, German Rotorhebel) will be installed. This rotor-rod will be joint with swivel-rod above by a third middle bearing (MG, German Mittel- oder Massegelenk), nearby which effective masse could be arranged.

Downside at EVBER 11 schematically a longitudinal section view resp. a view top-down is shown, where all parts are drawn symmetric. Swivel-wheel (SR) practically a crank-shaft will be with a crank-bearing (SG). ´Connecting-rod´ of this crank-shaft, here is called swivel-rod (SH). At its outer end, it is connected by middle (masse-) bearing (MG) with the rotor-rod (RH, double installed thus symmetric). These rotor-rods again are beared outside by the rotor bearing (RG) on Bessler-wheel (BR). Instead of circle-shaped Bessler-wheel, a beam as rotor arm would be sufficient. Parallel to this modul a second could be installed.

Masse track
As a starting situation, 12-o´clock-position of rotor bearing (RG) will be assumed. Rotor-rod (RH) here will show downwards, nearby vertical. Masse point (MP) here is arranged for example at three quaters of rotor-rods length. At the inner end of rotor-rod, by middle resp. masse-bearing (MG) its joint with swivel-rod (SH). At inner ende of swivel-rod, it is joint by swivel-bearing (SG) with swivel-wheel (RS, here not drawn). Swivel-wheel resp. swivel-bearing will show vertical downwards. Both rods thus are in a position most stretched towards each other.

At this upside position, rotor-rod and swivel-rod as well will be in motion towards left. Masse point there will be accelerated towards left-outside. Swinging-outward of swivel-bearing will effect this acceleration essentially. Via 9-o´clock-position (all times that of rotor-bearing), masse will fall downward by maximum speed.

Afterward, swivel-rod will pull masse towards inside resp. vice versa, masse will now pull down swivel-bearing. By this design thus will be achieved, centrifugal forces of masse here primarily will weight on swivel-rod. So in this phase, centrifugal power will feed energy into back-swinging of pendulum mechanism. Opposite to a free swinging pendulum, this pendulum thus will be accelerated in addition and thus will show downside at middle position correspondingly higher speed resp. high kinetic energy.

Bessler-Hebel-Rad nach Evert In this ending downward-phase, speed of pendulum weight will be reduced. Masse now will pull via rotor-rod at roto-bearing, thus a turning momentum at Bessler-wheel will exist.

At upward-phse, from 6- to 3-o´clock-position, speed of effective masse will further be reduced. Pendulum, by energy feed before, thus will push masse upwards, thus will drive via rotor-rod and rotor-bearing the Bessler-wheel. Thus centrifugal power (of phase before) will be transferred (some time later) into turning momentum.

Nearby 3-o´clock-position, masse will come into a position vertical above swivel-bearing, i.e. will now weight on swivel-rod and will press down swivel-bearing until 12-o´clock-position. Thus the pendulum, from its outside dead-point will be accelerated to its position middle-downside, not only by its own weight but also by effective masse of rotor-rod.

That energy feed into pendulum mechanism, afterward will be available for essential acceleration of masse into downward-phase. As described above, this acceleration-power will add to gravity-power, until nearby 9-o´clock-position masse again will show maximum kinetic energy.

At this simple animation, outer rotor-bearing (green circle) and rotor-rod (red line) are shown. At middle bearing (between rotor-rod and swivel-rod), effective masse is marked (green circle-surface). Swivel-rod (blue line) is connected with swivel-bearing (blue circle). Swining motions of swivel-bearing (representing also corresponding swinging of external pendulum mechanism) is marked by radius (black line) of swivel-wheel around system axis (black central point).

Here one may clearly see, motions by highly different speed of effective masse, its effect at rods and bearings. Each position of this procedure with these elements, once more is shown at EVBER 13.

Sections of pendulum swinging
By the pictures of pendulum mechanism of Bessler-wheel, at previous chapter was deduced, maximum swinging section there would be 90 degrees at pendulum wheel. Solution there with rotor wheels did show, at running system even less pendulum swinging will be demanded.

Now here at this solution by rod-system, essential will be that masse at the end of upward-phase will weight onto swivel-wheel (analog to pendulum wheel there). This will mean, swivel-rod should come most early and stay most long below effective masse. That´s why here section of swinging is shown with some 110 degrees (instead of maximum 90 degrees above). Optimum of swinging area however will also depend on relations of length of rods and where masse-point will be arranged.

At EVBER 17 for example, relations of length are arranged correspondig to ´golden relations´. Track of effective masse does fit rather good to demands. Area of swivel here does show but some 78 degrees.

However, this track upside will show an abruptly acceleration to left. That´s why here, at upside position rotor-rod and swivel-rod totally stretched are (in order to make also this Bessler-maschine running both turning sences same kind). This suggestion obviously will not be good. With but little bit langer lever arms resp. (rotor-bearing but a bit further inside) all times there would be a ´knee´ showing all times ahead and track of masse would be pretty well and harmonic.

Besides relations of length here show, there are lots of other possibilities. Depending on arrangement of effective masse, section of pendulums swinging and pendulum weights as well must be coordinated. Probably also here, an asymmetric swinging of pendulum mechanism would show good results.

Bessler-rod-design
At picture EVBER 14 as an example, a design of this maschine schematically is shown, upside by side-view, downside by longitudinal sectional view. However, housing and bearing of shafts is not shown.

Turnable around system axis (SA) Bessler-wheel (BR) must be installed. There is no complete wheel neccessary, that´s why here but a beam as rotor arm is drawn. Outside at this rotor arm that rotor-bearing (RG) is installed. So effective mass is well beared, here these rotor arms are double. By a shaft, both rotor arms are connected, this shaft same time will be the rotor-bearing. At this bearing, the rotor-rod (RH) will be joint. Also this rotor-rod here is installed twice and symmetrical.

Around system axis also turnable will be the swivel-wheel (SR), which together with that swivel-bearing (SG) practically will be a crank-shaft. At this swivel-bearing the swivel-rod (DH) is mounted. Swivel-rod and rotor-rod are joint by middle bearing (MG).

Both these rods here for example are shaped that kind, nearby middle bearing center of masses will be arranged. Above this, middle bearing is build very heavy, thus will represent essential part of effective masse.

Below at longitudinal section view, Bessler-wheel at some area is shaped as a hollow shaft with rather small diameter, so there the main shaft could be beared within housing (here not shown). Below of, an input-/output gear wheel (AZ, German An-/Abtriebszahnrad) is marked, by which the system could be started resp. surplus of energy could be used. Quit downside, swivel-wheel above (resp. crank-shaft) is drawn once more, by which a conneting rod (PS) could manage connetion to external pendulum mechanism (here not shown), analog chapter above.

Mirrored to this modul, above (backward of) a second modul could be installed, correspondingly shifted. Middle wall of Bessler-wheel (resp. a middle beam) would represent fix connection of both moduls. Analogly a second external pendulum mechanism, counter swinging, would be to install. When two effective rod systems are installed, always one of will be at upward-, the other at downward-phase, so in sum a continuous turning momentum will exist. If the Bessler-wheel is build stable, based on flywheel masse a round runnig maschine will be achieved.

Bessler-principles
By conciderations above and design principles descirbed, Bessler-wheel inside not neccessarily must show rotor-gear-wheels like described at chapter above. Even by higher probabiliy, Bessler will have uses basic element of ´knee-bearing´ of external pendulum-mechanism analogly a second time inside his wheel.

As Bessler used diameters of two up to nearby four meters, construction of correspondingly large gear wheels would be hard. This internal rod-system however, quit easy can be build. Nevertheless I do suggest, wheel-concept above will show higher effectivity, especially when external pendulum mechanism would be replaced by better technology. On the other hand, this lever-arm-system does represent Bessler-principles exactly:

Acceleration of masse into downward-phase,
thus by relative low energy-input
to achieve maximum kinetic energy.
Temporary storage of high centrifugal forces of that motion,
feed back of energy in turning sence of system at right time,
thus to achieve surplus of turning momentum.
These Bessler-wheels, with internal wheel-systems or internal rod-systems, technically are not very ´elegant´, especially that complex external pendulum mechanism. Based at principles above, it will be easy to produce demanded motions by most simple and well known technology. Some of, at later chapter ´Advanced Bessler-wheels´ will be presented.

Bessler-reproduction
Nevertheless it would be extremly interesting, these suggestion claimed here to approve by real models. I ask everyone to build these ´historic maschines´ and I would be glad, soon to report here about experiments.
