Abstract

A dental amalgamator for automatic controlled manual mixing of compound capsules with operator controlled rotated drive input. The manual amalgamator comprises a self-contained capsule holder and integral gear drive means with a capsule access and placement. Controlled drive input determines proper capsule associated speed and duration assuring proper capsule preparation in a lightweight self-contained portable user-friendly platform.

Claims (15)

1 . A portable dental mixing device comprising:

a main support housing, a drive gear assembly having a rotational input and linear output,

a product capsule carrying assembly in direct communication with said drive gear assembly such that said linear output of said drive gear causes linear oscillation of said product capsule carrying assembly,

a sensing and timing means responsive to said linear oscillation of said product capsule carrying assembly, said sensing and timing means including a signal illumination that activates in response to said linear oscillation of said product capsule carrying assembly to indicate proper linear oscillation speed and duration has been achieved and maintained, and a source of power for said sensing and timing means.

2 . The portable dental mixing device set forth in claim 1 wherein said main support housing comprises,

a drive gear assembly receiving portion, a capsule carrier receiving portion with an access door and a handle grip portion.

3 . The portable dental mixing device set forth in claim 1 wherein said drive gear assembly includes a first and second interconnected planetary gear set,

a crank handle in communication with said first planetary gear set and an eccentric output with said second planetary gear set.

4 . The portable dental mixing device set forth in claim 1 wherein said product capsule carrying assembly comprises,

a capsule holder having a base, a fixed capsule receiving fitting and a movable capsule receiving clip in longitudinally spaced relation thereto on said base.

5 . The portable mixing device set forth in claim 1 wherein said sensor and timing means comprises,

a magnet and a proximity switch, a timing circuit and illumination activation circuit in communication with said proximity switch, a color LED in communication with said illuminated activation circuit,

said LED color changes in response to said rotational input and therefore said capsule carrier assembly linear oscillation speed and duration.

6 . The portable mixing device set forth in claim 1 wherein said source of power for said sensing and timing means comprises a battery.

7 . The portable mixing device set forth in claim 3 wherein said first and second interconnected planetary gear sets each have a fixed ring gear, said eccentric output comprises a bearing lug, a drive arm in communication with said bearing lug and said capsule carrier assembly.
