Abstract
Abstract A cistern flush mechanism providing dual volumetric displacement. The mechanism comprises a ball cock actuating arm pivotally carrying adjacent its free end a depending float arm, a spacer pivotally carried by one of said arms and movable between a first position interposed between said arms to close the ball cock after a lower volumetric flow, and a second position permitting a higher volumetric flow, and means for moving said spacer from its first to its second positions.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
242 words
A cistern ball cock control device comprising an arm adapted at one end for mounting to a ball cock as an actuating arm therefor, a second arm disposed in the same plane as said actuating arm, the actuating arm being pivotally connected adjacent its other end to an intermediate position of said second arm, one section of the float arm, considered as divided into two sections at the intermediate position thereof at which it is pivotally connected to the actuating arm, being adapted to support a float, the other section of the float arm being a non-float support section, a spacer movably mounted to one of said arms, the movable mounting of the spacer enabling movement of the spacer between two positions, one position being that where the spacer is interposed between the actuating arm and the non-float support section of the float arm such that the actuating arm and the float support section of the float arm are disposed in a non-aligned formation, means urging the spacer to tend to take-up this interposed position, the other position being that where the spacer extends laterally with respect to said plane and therefore is clear of that interposed position, and an operating member, and means for mounting said operating member in a cistern so as to extend through the cistern casing toward said spacer to enable, when the device is mounted in situ, the spacer to be displaced clear of the interposed position.
Claim 2
Dependent Claim
242 words
A cistern ball cock control device comprising an arm adapted at one end for mounting to a ball cock as an actuating arm therefor, a second arm disposed in the same plane as said actuating arm, the actuating arm being pivotally connected adjacent its other end to an intermediate position of said second arm, one section of the float arm, considered as divided into two sections at the intermediate position thereof at which it is pivotally connected to the actuating arm, being adapted to support a float, the other section of the float arm being a non-float support section, a spacer movably mounted to one of said arms, the movable mounting of the spacer enabling movement of the spacer between two positions, one position being that where the spacer is interposed between the actuating arm and the non-float support section of the float arm such that the actuating arm and the float support section of the float arm are disposed in a non-aligned formation, means urging the spacer to tend to take-up this interposed position, the other position being that where the spacer extends laterally with respect to said plane and therefore is clear of that interposed position, and an operating member, and means for mounting said operating member in a cistern so as to extend through the cistern casing toward said spacer to enable, when the device is mounted in situ, the spacer to be displaced clear of the interposed position.
Claim 3
Dependent Claim
32 words
A cistern ball cock control device as claimed in claim 1 wherein the float support section of the float arm is adapted to retain the free end of a float retaining arm.
Claim 4
Dependent Claim
32 words
A cistern ball cock device as claimed in claim 1 wherein the float arm includes a float as an integral part thereof, the float arm being formed from a readily pliable material.
Claim 5
Dependent Claim
103 words
A cistern ball cock device as claimed in claim 1 wherein the operating member is comprised of two elements, one element being adapted for mounting through an aperture in the cistern's casing to be slidably operative therethrough, and the other element being longitudinally L-shaped, an aperture formed in an upstanding portion of the actuating arm adjacent and laterally of the interposed position of the spacer, one end of said L-shaped element being mounted in said aperture, and a transversely disposed aperture provided adjacent the inner end of the first element, the other end of said L-shaped element frictionally fitting into said last-mentioned aperture.
Claim 6
Dependent Claim
95 words
A cistern ball cock control device as claimed in claim 1, said non-float section of the float arm having a free end, wherein the spacer is mounted between a pair of lugs formed laterally of and adjacent the free end of the non-flaot section of the float arm, whereby, in situ, the spacer tends to depend downwardly of the lugs to take-up its interposed position, a projection being formed on the actuating arm extending laterally in the same direction as said lugs, and the lugs positioning the spacer such that it depends onto the projection.
Claim 7
Dependent Claim
20 words
A cistern ball cock device as claimed in claim 5, said spacer having a free end, said end being weighted.
Claim 8
Dependent Claim
88 words
A cistern ball cock control device as claimed in claim 1, wherein the spacer is pivotally attached between a pair of laterally positioned lugs formed on the actuating arm, the spacer incorporating a downwardly depending tail section, the non-float section of the float arm having a free end, a projection being formed adjacent the free end of the non-float section of the float arm extending laterally in the same direction as said lugs such that the spacer tends to interpose itself between its mounting lugs and the projection.
Claim 9
Dependent Claim
19 words
A cistern ball cock device as claimed in claim 7 wherein the tail section of the spacer is weighted.
Claim 10
Dependent Claim
117 words
A cistern ball cock control device as claimed in claim 1 wherein the actuating arm is formed with a bifurcated upstanding portion at that end thereof which is pivotally connected to the float arm, the sections of the bifurcated portion being disposed parallel to and laterally of the longitudinal axis of the actuating arm and aligned apertures being formed in these sections, the float arm being formed with two opposingly positioned and laterally extending stub axial type projections intermediate of its length whereby the sections of the actuating arm can be temporarily influenced apart and the float arm positioned therebetween to home the projections within the apertures to pivotally connect the actuating arm to the float arm.
