ABSTRACT:
A scoop with a counter for powder material includes a scooping cup with a handle and a pusher that can slide to and fro on the handle of the scoop. On the front end of the pusher is a cover ring and on the rear end of the pusher is a top plate. At the end of the handle of the scooping cup is fitted a housing that is composed of a left casing and a right casing. On each casing there is a window and inside the casings is fitted a counter ratchet. A digit frame in a ring arrangement is attached to both sides of the counter ratchet. On the lower part of the housing is an opening so a toothed side of the counter ratchet is exposed to facilitate resetting adjustment. Also in the housing and at the toothed side of the counter ratchet is a flexible fixing plate to fix the counter ratchet. In operation, the pusher may be slid across the scooping cup where the cover ring at the front end of the pusher will level the powder material in the scooping cup to obtain a constant quantity of powder material. When the pusher is slid back, the top plate at the rear of the pusher will push and turn the counter ratchet which will then turn the next digit of the digit frame to count scooping frequency.
