On the top of this lever is a catchtermed the taking-up lever catch; this is a misnomer, forit is rather a propeller pushing the ratchet wheel around,one tooth at a movement. As the wheel is pushed for-ward, a retaining catch takes hold and keeps it in theposition to which it has been pushed. This taking-up.

The stud carrying therack wheel passes through a bracket to the outside of theloom frame where it receives the change pinion, n, andfrom this fact is called the pinion wheel stud.

Thequantity of picks put into the cloth is governed by thenumber of teeth contained in the change pinion, n ; thesmaller the number the more are the picks put in; thegreater the number, the fewer will the cloth contain.
