Crank and Slotted Lever
Product Code : JA-PLE-4150
The Crank and Slotted Lever (SKU JA-PLE-4150) is a working board model of the quick-return mechanism used on cutting machines such as the shaper, in which a rotating crank drives a slotted lever so that the tool returns faster than it cuts. This crank and slotted lever quick return mechanism model is one of a series of sixteen A3 mechanism boards, and JaincoLab supplies it for theory of machines teaching.
Specifications
The mechanism is mounted on an A3 white melamine board with amber-coloured Perspex links on hollow-rivet pivots that accept a pencil; the tool is carried on a sliding ram in guides driven by link AB, and the stroke length depends on the length of link OC.

Applications of the crank and slotted lever quick return mechanism model
Students turn the crank and watch the ram advance slowly on the working stroke and return quickly, then trace the loci of the joints to compare link speeds and to see how the difference between cutting time and return time arises.
- Determining the loci of the moving parts of the quick-return mechanism
- Comparing which links move faster than others during a cycle
- Relating stroke length to the length of link OC
- Explaining the quick-return action of shaping and slotting machines in workshop technology classes

Frequently asked questions
What does the crank and slotted lever model show?
It shows the quick-return motion used to return a cutting tool faster than the work stroke.
What sets the length of stroke?
The stroke length depends on the length of link OC.
How are the loci recorded?
A pencil placed in the hollow rivets transfers the paths of the joints to paper clipped to the board.
