Elliptic Trammel
Product Code : JA-PLE-4186
The Elliptic Trammel (SKU JA-PLE-4186) is a working mechanism model that generates an ellipse, built on an A3 board for classroom, drawing-office and laboratory teaching. Two guide slots crossing at right angles carry the sliders of a trammel bar, and the end point of the bar traces the ellipse. This elliptic trammel mechanism model is one of a series of sixteen board-mounted mechanisms used in engineering drawing, applied mechanics and physics classes.
Specifications
The model has two guide slots intersecting at their mid-points at 90 degrees, forming the base lines of the major and minor axes, and a trammel bar with two variable-position sliders and an end point that traces the locus.

Applications of the elliptic trammel mechanism model
Students move the trammel bar by hand, watch the end point sweep out an ellipse and then record the loci of the joints on paper, which links the geometry of the ellipse to the motion of a real mechanism.
- Drawing an ellipse from its major and minor axes with the trammel method
- Plotting the loci of the moving parts of the mechanism
- Studying how changing the slider positions changes the shape of the ellipse
- Comparing the speeds of different points on the moving links
- Engineering drawing, theory of machines and applied mechanics classes in polytechnics, TVET institutes and colleges

Frequently asked questions
What does the elliptic trammel demonstrate?
It is a standard mechanism for generating an ellipse; the end point of the trammel bar traces the ellipse as its sliders run in two guide slots at 90 degrees.
What is the model made of?
The moving parts are amber-coloured Perspex pivoted with hollow rivets, mounted on a white A3 melamine board.
Can the loci be drawn on paper?
Yes. The hollow rivets accept a pencil so the loci of the joints can be transferred to a sheet of paper clipped to the board.
