Abstract

Abstract A rule for measuring meters or other units and sub-divisions thereof, the rule comprising a body section having indicia which defines units of measure, there being provided at one end of the body section a longitudinally movable head section having indicia which defines sub-divisions of one unit of measure. Movement of the head section is accomplished by means of a motion translating mechanism which is actuated upon manual rotation of a dial, or the like, the dial having readily viewed indicia which indicates the distance the head section is projected from the body section upon actuation of the mechanism.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 316 words
A measuring device comprising an elongate generally flat body section terminating at one end in a flat end surface disposed substantially perpendicular to the longitudinal axis of said body section, at least one of the side edges of said body section being provided with indicia defining units of measure, characterized by A. a slide portion carried adjacent said one end of said body portion, said slide portion including 1. a head section of substantially the same cross section size and configuration as said body section, said head section a. extending outwardly from said one end externally of said body section, b. being arranged in axial alignment with said body portion to form a uniform continuation thereof, and c. provided along at least one edge thereof with indicia aligned with the indicia on said body portion and defining subdivisions of one of said units of measure, and 2. support means comprising an elongate arm extending transversely from one end of said head section for engagement with said body section, B. longitudinally extending support surfaces provided in said body section, said support surfaces 1. opening through said end surface of said body section to define an aperature sized to receive said elongate arm, and 2. being positioned to slidingly support said arm and permit only longitudinal reciprocal movement thereof relative to said body section, and C. manually actuable operating means mounted on said body section and operatively engaging said arm for moving said slide portion between 1. a retracted position wherein said head section is contiguous with said body section and said subdivisions form a direct continuation of said units of measure, and 2. a projected position wherein said head section is spaced from said body section, D. said operating means being provided with indicia which indicate the extent of movement of said head section away from said body section in response to actuation of said operating means.
Claim 2
Dependent Claim 316 words
A measuring device comprising an elongate generally flat body section terminating at one end in a flat end surface disposed substantially perpendicular to the longitudinal axis of said body section, at least one of the side edges of said body section being provided with indicia defining units of measure, characterized by A. a slide portion carried adjacent said one end of said body portion, said slide portion including 1. a head section of substantially the same cross section size and configuration as said body section, said head section a. extending outwardly from said one end externally of said body section, b. being arranged in axial alignment with said body portion to form a uniform continuation thereof, and c. provided along at least one edge thereof with indicia aligned with the indicia on said body portion and defining subdivisions of one of said units of measure, and 2. support means comprising an elongate arm extending transversely from one end of said head section for engagement with said body section, B. longitudinally extending support surfaces provided in said body section, said support surfaces 1. opening through said end surface of said body section to define an aperature sized to receive said elongate arm, and 2. being positioned to slidingly support said arm and permit only longitudinal reciprocal movement thereof relative to said body section, and C. manually actuable operating means mounted on said body section and operatively engaging said arm for moving said slide portion between 1. a retracted position wherein said head section is contiguous with said body section and said subdivisions form a direct continuation of said units of measure, and 2. a projected position wherein said head section is spaced from said body section, D. said operating means being provided with indicia which indicate the extent of movement of said head section away from said body section in response to actuation of said operating means.
Claim 3
Dependent Claim 20 words
an actuating portion extending from said rotatable member into said groove in operative engagement with one edge of said arm.
Claim 4
Dependent Claim 20 words
an actuating portion extending from said rotatable member into said groove in operative engagement with one edge of said arm.
Claim 5
Dependent Claim 34 words
support means comprising an elongate arm extending transversely from one end of said head section for engagement with said body section, B. longitudinally extending support surfaces provided in said body section, said support surfaces
Claim 6
Dependent Claim 34 words
support means comprising an elongate arm extending transversely from one end of said head section for engagement with said body section, B. longitudinally extending support surfaces provided in said body section, said support surfaces
Claim 7
Dependent Claim 44 words
a projected position wherein said head section is spaced from said body section, D. said operating means being provided with indicia which indicate the extent of movement of said head section away from said body section in response to actuation of said operating means.
Claim 8
Dependent Claim 44 words
a projected position wherein said head section is spaced from said body section, D. said operating means being provided with indicia which indicate the extent of movement of said head section away from said body section in response to actuation of said operating means.
Claim 9
Dependent Claim 61 words
A measuring device according to claim 1, wherein A. said support surfaces are defined by a longitudinally disposed groove formed in one of the outer surfaces of said body section and opening through said end surface thereof, the sides of said grooves diverging from one another and from a plane disposed perpendicular to the surface in which said groove is formed.
Claim 10
Dependent Claim 36 words
a driver carried by and rotatable with said shaft, said driver being engaged with said one edge of said arm to move said slide portion longitudinally relative to said body section upon rotation of said dial.
Claim 11
Dependent Claim 36 words
a driver carried by and rotatable with said shaft, said driver being engaged with said one edge of said arm to move said slide portion longitudinally relative to said body section upon rotation of said dial.
Claim 12
Dependent Claim 36 words
A measuring device according to claim 11, wherein A. said groove and said arm are generally complimentary in cross-sectional configuration, said arm being snugly yet slidingly engaged in said groove for limited longitudinal reciprocal movement therEin.
Claim 13
Dependent Claim 13 words
A measuring device according to claim 4, wherein A. said operating means includes
Claim 14
Dependent Claim 32 words
A measuring device according to claim 4, wherein A. said rotatable member comprises a dial which is provided with indicia defining a plurality of equally spaced segments, B. said actuating portion includes
Claim 15
Dependent Claim 55 words
A measuring device according to claim 5, wherein A. said driver comprises a pinion gear, and B. a gear rack section is provided along said one edge of said arm in engagement with said pinion, and C. means is provided for limiting the longitudinal reciprocal movement of said slide portion away from said body section.
Claim 16
Dependent Claim 47 words
A measuring device according to claim 6, wherein said limiting means comprises A. a shoulder provided by said body portion contiguous with said groove, and B. an extension provided on said arm adapted to abutt said shoulder upon movement of said slide portion to said extended position.
Claim 17
Dependent Claim 67 words
A measuring device according to claim 6, wherein A. said segments on said dial are numbered consecutively, each segment defining a space greater than one of said sub-divisions of measure, and B. said pinion gear and rack move said slide portion a distance equal to one of said sub-divisions of measure in response to rotation of said dial through an arc equivalent to one of said segments.
