Claw Mechanism Science Labs
Product Code : JA-PLE-4193
The Claw Mechanism (SKU JA-PLE-4193) is a working model of the standard mechanism for intermittent feed, the principle used to advance film frame by frame in cine cameras and projectors. Two meshing gear wheels drive a slotted arm whose claw traces a loop with a flat side on every revolution. This claw mechanism model for intermittent motion is one of a series of sixteen A3 board-mounted mechanisms used in theory of machines and engineering drawing teaching.
Specifications
A pair of gear wheels pivoted at O and P run in mesh at the same speed; a pivot on one wheel carries a moving arm, a pin on the other wheel slides in a curved slot in the arm, and an extension of the arm ends in a fine claw.

Applications of the claw mechanism model
Tracing the claw path shows students how steady rotation of two gears is turned into an intermittent push: the flat side of the loop is where the claw engages and feeds, and the rest of the loop is its return.
- Demonstrating intermittent feed from continuous rotation
- Tracing the loop with a flat side described by the claw on each revolution
- Explaining film advance in cine cameras and projectors
- Comparing the claw with other intermittent-motion mechanisms such as the carrier slide
- Theory of machines and engineering drawing classes in polytechnics, TVET institutes and colleges

JaincoLab supplies individual models, complete mechanism sets for technical training and export consignments to buyers in Africa, the Middle East and South and South-East Asia.
Frequently asked questions
What motion does the claw mechanism produce?
An intermittent feed: the claw traces a loop with a flat side each time the gear wheels make one revolution.
How is the arm driven?
Two gear wheels pivoted at O and P run in mesh at the same speed; one carries the arm pivot and a pin on the other slides in a curved slot in the arm.
