Abstract
Abstract A gauge for measuring a change in the spacing between two locations has a support that is fixed at one of the locations and a wheel pivotal on the support about an upright axis and having an outer periphery. The wheel periphery and the support have juxtaposed portions one of which is provided with a pointer and the other of which is provided with a scale so that the pointer moves along the scale as the wheel pivots on the support. A flexible belt has an inner end anchored on the support, a middle portion, and an outer end attached at the other location. This outer end is releasably fixed to the wheel periphery and a spring urges the wheel rotationally on the support in a direction pulling the middle belt portion taut between the locations. Thus as the two locations move relative to each other the pointer moves relative to the scale.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
167 words
A gauge for measuring a change in a dimension between one location and an adjacent location on at least one object, the gauge comprising: a support; means for fixing the support at one of the locations; a wheel pivotal on the support about an upright axis and having an outer periphery, the wheel periphery and the support having juxtaposed portions one of which is provided with a pointer and the other of which is provided with a scale, whereby the pointer moves along the scale as the wheel pivots on the support; a flexible belt having an inner end anchored at the other location, a middle portion, and an outer end lying against the periphery of the wheel; means for fixing the outer end to the wheel periphery; and spring means for urging the wheel rotationally on the support in a direction pulling the middle belt portion tight between the locations, whereby as the relative positions of the locations changes the pointer move relative to the scale.
Claim 2
Dependent Claim
167 words
A gauge for measuring a change in a dimension between one location and an adjacent location on at least one object, the gauge comprising: a support; means for fixing the support at one of the locations; a wheel pivotal on the support about an upright axis and having an outer periphery, the wheel periphery and the support having juxtaposed portions one of which is provided with a pointer and the other of which is provided with a scale, whereby the pointer moves along the scale as the wheel pivots on the support; a flexible belt having an inner end anchored at the other location, a middle portion, and an outer end lying against the periphery of the wheel; means for fixing the outer end to the wheel periphery; and spring means for urging the wheel rotationally on the support in a direction pulling the middle belt portion tight between the locations, whereby as the relative positions of the locations changes the pointer move relative to the scale.
Claim 3
Dependent Claim
13 words
The gauge defined in claim 1 wherein the belt is a metal strap.
Claim 4
Dependent Claim
20 words
The gauge defined in claim 1 wherein the scale is on the wheel and the pointer is on the support.
Claim 5
Dependent Claim
36 words
The gauge defined in claim 1 wherein the means for fixing the outer end is a radially displaceable clamp element carried on the wheel and capable of pinching the outer belt end against the wheel periphery.
Claim 6
Dependent Claim
36 words
The gauge defined in claim 1 wherein the spring means includes a coil spring extending secantally of the wheel axis and having one end fixed on the support and an opposite end fixed on the wheel.
Claim 7
Dependent Claim
45 words
The gauge defined in claim 1 wherein the belt includes an inner belt piece fixed permanently to the support and having an outer end formed as a hook and an outer belt piece having an inner end formed as an eye engaged over the hook.
Claim 8
Dependent Claim
29 words
The gauge defined in claim 1 further comprising at least one staple engaged over the belt with the trunk and forming for the belt a guide on the trunk.
Claim 9
Dependent Claim
161 words
A gauge for measuring an increase in girth of an upright tree trunk, the gauge comprising: a support; means for fixing the support to the tree trunk; a wheel pivotal on the support about an upright axis and having an outer periphery, the wheel periphery and the support having juxtaposed portions one of which is provided with a pointer and the other of which is provided with a scale, whereby the pointer moves along the scale as the wheel pivots on the support; a flexible belt having an inner end anchored on the support, a middle portion wrapped around the trunk level with the support, and an outer end lying against the periphery of the wheel: means for fixing the outer end to the wheel periphery; and spring means for urging the wheel rotationally on the support in a direction pulling the middle belt portion tight around the trunk, whereby as the trunk grows the pointer moves relative to the scale.
Claim 10
Dependent Claim
161 words
A gauge for measuring an increase in girth of an upright tree trunk, the gauge comprising: a support; means for fixing the support to the tree trunk; a wheel pivotal on the support about an upright axis and having an outer periphery, the wheel periphery and the support having juxtaposed portions one of which is provided with a pointer and the other of which is provided with a scale, whereby the pointer moves along the scale as the wheel pivots on the support; a flexible belt having an inner end anchored on the support, a middle portion wrapped around the trunk level with the support, and an outer end lying against the periphery of the wheel: means for fixing the outer end to the wheel periphery; and spring means for urging the wheel rotationally on the support in a direction pulling the middle belt portion tight around the trunk, whereby as the trunk grows the pointer moves relative to the scale.
Claim 11
Dependent Claim
13 words
The gauge defined in claim 8 wherein the belt is a metal strap.
Claim 12
Dependent Claim
20 words
The gauge defined in claim 8 wherein the scale is on the wheel and the pointer is on the support.
Claim 13
Dependent Claim
36 words
The gauge defined in claim 8 wherein the means for fixing the outer end is a radially displaceable clamp element carried on the wheel and capable of pinching the outer belt end against the wheel periphery.
Claim 14
Dependent Claim
36 words
The gauge defined in claim 8 wherein the spring means includes a coil spring extending secantally of the wheel axis and having one end fixed on the support and an opposite end fixed on the wheel.
Claim 15
Dependent Claim
45 words
The gauge defined in claim 8 wherein the belt includes an inner belt piece fixed permanently to the support and having an outer end formed as a hook and an outer belt piece having an inner end formed as an eye engaged over the hook.
Claim 16
Dependent Claim
29 words
The gauge defined in claim 8 further comprising at least one staple engaged over the belt with the trunk and forming for the belt a guide on the trunk.
