Abstract
Abstract An indicator principally for measuring fat depth on animal carcasses includes a base and has a probe extending outwardly from the base. The probe defines at or adjacent its end remote from the base a first reference point and a moveable contact plate provides a second reference point. An indicator is provided to give an indication of the distance between the first and second reference points. An elastic means is provided between the base and the contact plate, the elasticity of the elastic means, which in the preferred form comprises springs, being selected so that in use the contact plate compresses the material, such as the surface of the animal carcass, by a predetermined amount.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
180 words
An indicator for measureing the fat layer depth of an animal carcass comprising a base, a probe, means fixedly securing said probe with respect to said base, said probe extending from said base and insertable into an animal carcass, a first reference point defined as part of said probe and disposed proximate the probe and remote from said base, a contact member having defined thereon a second reference point, display means for providing an indication of the distance between said first and second reference points, and elastic means connected between said base and said contact member for elastically opposing increased separation of said first and second reference points, said contact member being positioned to contact said animal carcass upon insertion of said probe into said carcass to a predetermined depth, the elasticity of said elastic means being selected so that in use said contact member, upon contacting the carcass, compresses the carcass fat layer to a depth which is substantially equal to the expected shrinkage of the carcass fat layer before said probe can be further inserted into the carcass.
Claim 2
Dependent Claim
180 words
An indicator for measureing the fat layer depth of an animal carcass comprising a base, a probe, means fixedly securing said probe with respect to said base, said probe extending from said base and insertable into an animal carcass, a first reference point defined as part of said probe and disposed proximate the probe and remote from said base, a contact member having defined thereon a second reference point, display means for providing an indication of the distance between said first and second reference points, and elastic means connected between said base and said contact member for elastically opposing increased separation of said first and second reference points, said contact member being positioned to contact said animal carcass upon insertion of said probe into said carcass to a predetermined depth, the elasticity of said elastic means being selected so that in use said contact member, upon contacting the carcass, compresses the carcass fat layer to a depth which is substantially equal to the expected shrinkage of the carcass fat layer before said probe can be further inserted into the carcass.
Claim 3
Dependent Claim
25 words
An indicator as claimed in claim 1 wherein said shrinkage comprises the shrinkage of said fat layer between hot and cold conditions of said carcass.
Claim 4
Dependent Claim
31 words
An indicator as claimed in claim 1 wherein said base comprises a housing and said probe extends from said housing, said contact member including an apertured plate positioned about said probe.
Claim 5
Dependent Claim
46 words
An indicator as claimed in claim 3 wherein parts of said contact member extend into said housing through an aperture in said housing and said elastic means are provided between said parts of said contact plate within said housing and the inner wall of said housing.
Claim 6
Dependent Claim
24 words
An indicator as claimed in claim 3 wherein said elatic means comprise one or more springs connected between said contact member and said housing.
Claim 7
Dependent Claim
44 words
An indicator as claimed in claim 3 wherein said contact member includes a back plate within said housing, said spring or springs being provided between said back plate and said housing so as to extend as said contact member is moved towards said housing.
Claim 8
Dependent Claim
58 words
An indicator as claimed in claim 3 further including display means which display means include a light emitter and a photo cell within said housing and a grille or grid positioned between said light emitter and said photo cell said grille or grid being mounted on said contact member to be moved as said contact plate is moved.
