Abstract
Abstract Two directional measuring device having an elongate measuring member having a distance measuring scale along its length and another measuring member to measure distance in another direction. The two members are relatively moveable in the direction of the measuring scale of the elongate member and the other member has diverging surfaces extending generally in that direction and a distance measuring scale to indicate, at spaced positions, the distance apart of the diverging surfaces.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
137 words
A device for simultaneously measuring the depth and width of a space comprising an elongate depth measuring member having a distance measuring scale provided along its length to record distances from one end of the elongate member, and a width measuring member mounted upon the depth measuring member for movement along the depth measuring member in positions spaced from said one end, the width measuring member having surfaces which extend generally in the direction of the length of the elongate member and diverge as they extend away from said one end of the depth measuring member and with the depth measuring member lying within the confines of the diverging surfaces, the width measuring member having a distance measuring scale which indicates, at spaced positions, the distance apart of the diverging surfaces at each of the spaced positions.
Claim 2
Independent Claim
137 words
A device for simultaneously measuring the depth and width of a space comprising an elongate depth measuring member having a distance measuring scale provided along its length to record distances from one end of the elongate member, and a width measuring member mounted upon the depth measuring member for movement along the depth measuring member in positions spaced from said one end, the width measuring member having surfaces which extend generally in the direction of the length of the elongate member and diverge as they extend away from said one end of the depth measuring member and with the depth measuring member lying within the confines of the diverging surfaces, the width measuring member having a distance measuring scale which indicates, at spaced positions, the distance apart of the diverging surfaces at each of the spaced positions.
Claim 3
Dependent Claim
21 words
A device according to claim 1 wherein said width measuring member comprises a plate with side edges forming its diverging surfaces.
Claim 4
Dependent Claim
30 words
A device according to claim 2 wherein the depth measuring member is in the form of a flat strip and the width measuring member is mounted upon the flat strip.
Claim 5
Dependent Claim
40 words
A device according to claim 3 wherein the flat strip is formed with a longitudinal slot and said width measuring member has mounting means received through the slot and by which the members are relatively moveable, one upon the other.
Claim 6
Independent Claim
148 words
A device for simultaneously measuring the depth and width of a space comprising a handle, an elongate depth measuring member in the form of a flat strip extending from the handle and having a distance measuring scale provided along its length to record distances from one end of the strip, and a width measuring member, said width measuring member mounted upon the strip for movement along the strip in positions spaced from said one end, the width measuring member having side edges extending generally in the direction of the length of the strip and diverging as they extend away from said one end of the strip and with the depth measuring member lying between the confines of the diverging side edges, the width measuring member having a distance measuring scale which indicates, at spaced positions, the distance apart of the diverging surfaces at each of the spaced positions.
Claim 7
Independent Claim
148 words
A device for simultaneously measuring the depth and width of a space comprising a handle, an elongate depth measuring member in the form of a flat strip extending from the handle and having a distance measuring scale provided along its length to record distances from one end of the strip, and a width measuring member, said width measuring member mounted upon the strip for movement along the strip in positions spaced from said one end, the width measuring member having side edges extending generally in the direction of the length of the strip and diverging as they extend away from said one end of the strip and with the depth measuring member lying between the confines of the diverging side edges, the width measuring member having a distance measuring scale which indicates, at spaced positions, the distance apart of the diverging surfaces at each of the spaced positions.
Claim 8
Dependent Claim
27 words
A device according to claim 5 wherein each member is planar and said width measuring member is mounted to move along one side edge of the strip.
