Abstract
Abstract A counting device sensitive to change of position of a body involves two spaced stationary notched rings between which a ring notched along both of its edges moves. The cooperation between the notches of the spaced stationary rings and the movable ring is such that when the stationary structure is inverted or tilted, the movable member advances a predetermined distance, and it carries the sequence of numbers, one of which is visible, to indicate the number of such inversions or tilts.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
70 words
A counting device sensitive to change of position including a stationary structure which is mountable on an object whose position is subject to change, said stationary structure including two spaced elements, each having first and second toothed portions respectively extending towards each other, a member movable between said spaced elements and having first and second toothed portions engageable respectively with the first and second toothed portions of said stationary structure.
Claim 2
Dependent Claim
70 words
A counting device sensitive to change of position including a stationary structure which is mountable on an object whose position is subject to change, said stationary structure including two spaced elements, each having first and second toothed portions respectively extending towards each other, a member movable between said spaced elements and having first and second toothed portions engageable respectively with the first and second toothed portions of said stationary structure.
Claim 3
Dependent Claim
64 words
A counting device as set forth in claim 1 in which the minimum spacing between said first and second toothed portions of said stationary structure is somewhat less than the minimum distance between the ends of said first and second toothed portions of said movable member to limit movement of movable member to a distance equal to adjacent toothed portions of said stationary member.
Claim 4
Dependent Claim
47 words
A counting device as set forth in claim 1 in which engageable first toothed portions of said stationary structure and said movable member cooperate such that one toothed portion of one enters a notched portion in the other defined by two adjacent toothed portions of the other.
Claim 5
Dependent Claim
59 words
A counting device as set forth in claim 3 in which said one toothed portion is a generally triangular portion and extends towards said two spaced portions and terminates in an apex portion, each of said two toothed portions each being generally a truncated triangular portion and extending towards said one toothed portion and terminating in a blunt portion.
Claim 6
Dependent Claim
52 words
A counting device as set forth in claim 4 in which said triangular portion and said truncated triangular portions are each defined by a surface which extends generally perpendicular to the direction of movement of said movable member and a surface is inclined in the direction of movement of said movable member.
Claim 7
Dependent Claim
39 words
A counting device as set forth in claim 5 in which there is engagement between said triangular portion and said truncated triangular portion which prevents said movable member from moving a distance greater than one of said notched portions.
Claim 8
Dependent Claim
47 words
A counting device as set forth in claim 1 in which said two spaced elements are in the form of rings and said member is also in the form of a ring all encircling the pouring opening of a bottle upon which said stationary structure is mounted.
Claim 9
Dependent Claim
41 words
A counting device as set forth in claim 7 in which said stationary structure is mounted on a liquid measuring device on said bottle which serves to meter out a predetermined amount of liquid from said bottle for each inversion thereof.
