Download samples and experiments for the Linkage mechanism designer and simulator.

Owl Pussycat Mechanism


image

Reverse engineered mechanism based on Keith Newstead’s Owl and Pussycat Automaton seen here. Keith, if you don’t want this published, let me know and I’ll remove it.

Speed Changing Oscillator


image

This oscillating mechanism changes speed during an oscillation. A rotary input will normally change the speed of the oscillator but the added Whitworth quick return mechanism makes it change in two ways.

Level Moving Table


image

This is a chain connected table leveling mechanism. The table moves left and right while remaining level with it’s original position.

Sliding Aperture


image

This is a complex aperture mechanism using curved path sliding connections.

Slide to Slider


image

This is a pair of sliding links whose position is controlled by another sliding connector. This is only recently supported in the Linkage program.

Front End Loader


image

This is a model of a front end loader bucket mechanism. I never actually tried to use “Always Manual” inputs during a video export, but it worked fine even with the animation running slower than real-time.

Alternate Front End Loader


image

This is another model of a front end loader bucket mechanism. I like the geometry of this one a bit more than the other one.

Gear and Chain Test


image

This is a test mechanism I created when I first added the gear and chain features. I just updated the video to show moving chains, something available in the latest (3.2.10) version of the software.

Box Transport Mechanism


image

A user wanted to build a box transport mechanism but the design used a problematic linkage; the simulator can’t simulate some type of mechanism. This is a redesign of that mechanism.

Two Whitworth quick return mechanisms, or something like that.

Hoeken Straight Line Mechanism


image

Hoeken Straight Line Mechanism by Karl Hoecken. The mechanism shows up online with the alternate spelling of his name for some reason. The Wikipedia page for this mecahnism seems to show a variation that is not as accurate as the mechanism show here and elsewhere online.

Ball Lifting Mechanism


image

This is a ball lifting mechanism for a rolling ball kinetic sculpture, also known as a marble run. This design was used to build a physical version of the mechanism, as seen in one of the videos below.

Gear Mechanism


image

Four gears in series. It is actually six gears on four shafts. When a gear unit is meshed with two other gears, that can create a single solid gear unit with two gears working as a unit.

Amplified Oscillation Mechanism


image

Linear and rotating inputs can directly create oscillating mechanisms that rotate up to almost 180 degrees. Using gears to up-convert the oscillation, the oscillating parts can move past the 180 degree limit.

Stephenson Locomotive Valve Mechanism


image

This is a variation of the Stephenson valve mechanism. The forward-neutral-reverse control is acomplished with a manual input linear actuator in the simulation. The video shows it being moved around to various positions.
