Abstract

Abstract An indicator device for a table dispenser has a first cylindrical rotatable member defining an aperture, a second cylindrical rotatable member arranged concentrically with respect to the first member, a third cylindrical member relatively fixed with respect to and concentric with the first and second members, means coupling the first and second members for rotation together in a first direction of rotation from a first position of the first member in which access through the aperture is not possible to a second position of the first member in which access through the aperture is possible for dispensing a tablet, means coupling the second and third members to prevent the rotation of the second member in the direction of rotation opposite to the first direction during the rotation of the first member from the second position to the first position and means to indicate, upon the restoration of the first member to its first position after it has been rotated to the second position, the time that a tablet is next due to be dispensed.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 157 words
An indicator device having a first cylindrical rotatable member, an aperture defined by the first member, a second cylindrical rotatable member arranged concentrically with respect to the first member, a third cylindrical member, the third cylindrical member being concentric with the first and second members, means coupling the first and second members for rotation together in a first direction of rotation from a first position of the first member in which access through the aperture is not possible to a second position of the first member in which access through the aperture is possible, means coupling the second and third members to prevent the rotation of the second member in the direction of rotation opposite to the first direction during the rotation of the first member from the second position to the first position and means to indicate the restoration of the first member to its first position after it has been rotated to the second position.
Claim 2
Dependent Claim 157 words
An indicator device having a first cylindrical rotatable member, an aperture defined by the first member, a second cylindrical rotatable member arranged concentrically with respect to the first member, a third cylindrical member, the third cylindrical member being concentric with the first and second members, means coupling the first and second members for rotation together in a first direction of rotation from a first position of the first member in which access through the aperture is not possible to a second position of the first member in which access through the aperture is possible, means coupling the second and third members to prevent the rotation of the second member in the direction of rotation opposite to the first direction during the rotation of the first member from the second position to the first position and means to indicate the restoration of the first member to its first position after it has been rotated to the second position.
Claim 3
Dependent Claim 23 words
An indicator device as claimed in claim 1 in which the second cylindrical member is arranged between the first and third cylindrical members.
Claim 4
Dependent Claim 55 words
An indicator device as claimed in claim 1 including first ratchet and pawl means coupling the first and second cylindrical members for rotation together in the first direction and second ratchet and pawl means coupling the second and third members together against rotation of the second member in the direction opposite to the first direction.
Claim 5
Dependent Claim 23 words
An indicator device as claimed in claim 1 including an end face on the first cylindrical member, the end face defining the aperture.
Claim 6
Dependent Claim 46 words
An indicator device as claimed in claim 1 including a second aperture defined by the first member, and markings on the second cylindrical member, the second aperture enabling a marking on the second cylindrical member to be disclosed to indicate the restoration of the first member.
