Abstract
Abstract The present invention provides a device for recording successive changes in indicia including a support structure, a front wall portion supported by the support structure, a display opening in the front wall portion, a fulcrum horizontally disposed above the opening on the rear side of the wall portion, an annular member on the rear side of the wall portion and through which the fulcrum extends eccentrically such that the annulus, when resting under its own weight on the fulcrum, presents a portion of its circumference against the opening and constructed and arranged such that manually pushing the annulus away from its rest position results in pivoting about the fulcrum and thereafter, in returning to its rest position under its own weight, moves circumferentially with respect to the fulcrum to present an adjacent circumferential portion to the opening.

A device for recording successive changes in indicia including a support structure, a front wall portion supported by the support structure, a display opening in the front wall portion,, a fulcrum horizontally disposed above the opening on the rear side of the wall portion, an annular member on the rear side of the wall portion and through which the fulcrum extends eccentrically such that the annulus, when resting under its own weight on the fulcrum, presents a portion of its circumference against the opening and constructed and arranged such that manually pushing the annulus away from its rest position results in pivoting about the fulcrum and thereafter, in returning to its rest position under its own weight, moves circumferentially with respect to the fulcrum to present an adjacent circumferential portion to the opening.

Claim 3
Dependent Claim
19 words
A device as claimed in claim 1 wherein the annulus bears a sequence of indicia about its outer circumference.
Claim 4
Dependent Claim
29 words
A device as claimed in claim 1, wherein the annulus is supported such that when in its rest position the centre of the annulus is aligned with the opening.
Claim 5
Dependent Claim
32 words
A device as claimed in claim 1 wherein the inner surface of the annulus is provided with abutments adapted to releasably engage said fulcrum to define predetermined rotational positions of the annulus.
Claim 6
Dependent Claim
35 words
A device as claimed in claim 1 wherein the outer surface of the annulus is provided with abutments adapted to releasably engage material of the front wall to define predetermined rotational positions of the annulus.
Claim 7
Dependent Claim
29 words
A device as claimed in claim 5, wherein the outer surface of the annulus is provided with a saw-tooth profile and wherein flanks of said profile define said abutments.
Claim 8
Dependent Claim
40 words
A device as claimed in claim 1, and including an abutment means with which the annulus is adapted to engage to limit said pivoting to a substantially constant value whereby the movement circumferentially as aforesaid is of substantially constant value.
