ABSTRACT:
A preset counter has a case and one or more counter units. Each counter unit has a number wheel, a first intermediate wheel in mesh with the number wheel, a preset wheel and a second intermediate wheel in mesh with the preset wheel. Said first intermediate wheel comprises a first wheel which is in mesh with said number wheel and whose rotation is prevented releasably by a locking means and a second wheel which is disposed in opposed relationship with said second intermediate wheel, resiliently connected through a clutch to said first wheel and is formed with a recess or notch cut into the peripheral surface thereof. When the preset wheel is rotated, its movement is transmitted through said second intermediate wheel to said second wheel, but not to said first wheel. When the number wheel is rotated, its movement is transmitted through said first wheel to said second wheel, but not to said second intermediate wheel. In each counter unit, when said notch and a contact roller are in line with each other, contacts are actuated. During the counting, a preset reading may be changed. A preset reading remains displayed on the preset wheels until the preset reading is reached.
