Abstract

An imprint wheel assembly is provided including a plurality of imprint wheels, means biasing the wheels axially toward each other, and detent means associated with each wheel for axially detenting such in a selected index position for imprinting of a selected date or other information.

Claims

1. An imprint wheel assembly for use with a data recorder, said assembly comprising:

a frame;

a shaft mounted to said frame;

a plurality of imprint wheels each rotatably mounted to said shaft for selective rotation about the axis of said shaft to selected positions, said imprint wheels being axially disposed of each other and axially movable relative to said shaft;

means yieldably biasing said wheels axially toward each other; and

detent means associated with each of said wheels for axially detenting said wheels to maintain such in selected positions under the influence of said axial biasing means;

said detent means comprising a plurality of detent members each axially disposed adjacent a corresponding one of said plurality of wheels and normally retentively engaging said one wheel, each detent member separating the axially adjacent wheels from each other and including means for preventing rotation of the detent member about said shaft and allowing axial movement relative to said shaft against the influence of said biasing means, each said wheel and each adjacent said detent member including cooperating surfaces sloped at an angle to said axis and in sliding engagement while the associated wheel is rotated to a said selected position.

2. The assembly set forth in claim 1 wherein each of said detent members is comprised of a disc-like member mounted in engagement with one of said wheels.

3. The assembly set fortH in claim 1 wherein each said detent member is of generally disc-like configuration with a pair of opposite sides, one of said sides being substantially planar and the opposite of said sides including a said sloped detent surface.

4. The assembly set forth in claim 3 wherein said sloped detent surfaces define a plurality of wheel positions equal to the number of selected positions for each imprint wheel.

5. The assembly set forth in claim 1 wherein said rotation preventing means slideably engages said frame for allowing axial movement of the associated detent member relative to said frame.

6. The assembly set forth in claim 1 wherein said shaft includes a keyway, said rotation preventing means slideably engaging said keyway for allowing axial movement of the associated detent member relative to said shaft.
