Abstract
Abstract A machine for conducting precision measuring operations. The machine comprises an article-supporting work table and a sensor element moveable into contact with an article on the table. The sensor is moveable along three mutually perpendicular axes and the table is shiftable toward and away from the sensor to increase the flexibility and overall capacity of the machine.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
181 words
A machine for conducting precision measuring operations on an article, said machine comprising: a frame, an article-contacting sensor element carried by the frame, said element being reciprocably movable relative to the frame along a substantially rectilinear path of travel, a worktable having a generally planar article support surface, said support surface being disposed generally perpendicular to said path and facing said element, a plurality of elongated pillars fixed to the worktable in parallelism with said path, a plurality of guide channels in the frame, each one of said pillars being slidably received within a corresponding one of said channels, a piston and cylinder assembly coupled with said worktable and disposed for rectilinear extension and contraction for moving said worktable in general parallelism with said path, a number of teeth on each of said pillars longitudinally spaced therealong, and a spider including a ring rotatable about said assembly and an elongated arm for each pillar, each arm extending radially outwardly from the ring and including an outer block element positioned for engaging a tooth on the corresponding pillar upon rotating the spider.
Claim 2
Dependent Claim
181 words
A machine for conducting precision measuring operations on an article, said machine comprising: a frame, an article-contacting sensor element carried by the frame, said element being reciprocably movable relative to the frame along a substantially rectilinear path of travel, a worktable having a generally planar article support surface, said support surface being disposed generally perpendicular to said path and facing said element, a plurality of elongated pillars fixed to the worktable in parallelism with said path, a plurality of guide channels in the frame, each one of said pillars being slidably received within a corresponding one of said channels, a piston and cylinder assembly coupled with said worktable and disposed for rectilinear extension and contraction for moving said worktable in general parallelism with said path, a number of teeth on each of said pillars longitudinally spaced therealong, and a spider including a ring rotatable about said assembly and an elongated arm for each pillar, each arm extending radially outwardly from the ring and including an outer block element positioned for engaging a tooth on the corresponding pillar upon rotating the spider.
Claim 3
Dependent Claim
24 words
A machine as set forth in claim 1 wherein said pillars are equidistant from the assembly, said arms being substantially of the same length.
Claim 4
Dependent Claim
174 words
A measuring machine comprising a frame, a worktable mounted on said frame and having a planar support surface for a workpiece, a carriage rectilinearly slidable along a first coordinate direction, an outwardly projecting structure on said carriage, an outer member rectilinearly movable on said structure along a second coordinate direction perpendicular to said first direction, both said directions being parallel to said surface, and a sensor element overhanging said worktable and reciprocably movable on said outer member along a rectilinear path perpendicular to said surface, within a predetermined range of measurement, wherein the improvement comprises: guide means for guiding said worktable in a direction parallel to said path, means for moving said worktable along said guide means, a pillar associated with said guide means and parallel thereto, a number of equidistant stop means located on said pillar, and locking means for locking said worktable on a selected one of said stop means to bring the part of said workpiece to be measured within the range of movement of said sensor element on said path.
Claim 5
Dependent Claim
174 words
A measuring machine comprising a frame, a worktable mounted on said frame and having a planar support surface for a workpiece, a carriage rectilinearly slidable along a first coordinate direction, an outwardly projecting structure on said carriage, an outer member rectilinearly movable on said structure along a second coordinate direction perpendicular to said first direction, both said directions being parallel to said surface, and a sensor element overhanging said worktable and reciprocably movable on said outer member along a rectilinear path perpendicular to said surface, within a predetermined range of measurement, wherein the improvement comprises: guide means for guiding said worktable in a direction parallel to said path, means for moving said worktable along said guide means, a pillar associated with said guide means and parallel thereto, a number of equidistant stop means located on said pillar, and locking means for locking said worktable on a selected one of said stop means to bring the part of said workpiece to be measured within the range of movement of said sensor element on said path.
Claim 6
Dependent Claim
62 words
A machine as set forth in claim 3, comprising a plurality of pillars fixed to said worktable, and a plurality of guide channels in said frame, each one of said pillars being slidably received within a corresponding one of said channels, and said stop mEans comprising teeth provided on at least one of said pillars and individually engageable by said locking means.
Claim 7
Dependent Claim
72 words
A machine as set forth in claim 4, wherein said moving means comprises a hydraulic cylinder secured to said frame and a piston operating in the cylinder and secured to said worktable, and said stop means includes a member manually shiftable into and out of engagement with said teeth, said shiftable member being adapted to arrestably engage a surface of a selected one of said teeth substantially parallel to said support surface.
Claim 8
Dependent Claim
50 words
A machine as set forth in claim 4, wherein said guide means comprises an abutment member on said worktable and a guide member parallel to said pillars and engageable by said abutment member, and spring means yieldably biasing said worktable to cause said abutment member to engage said guide member.
Claim 9
Dependent Claim
86 words
A machine as set forth in claim 20, comprising a plurality of pillars fixed to said worktable and a plurality of guide channels in said frame, each one of said pillars being slidably received within a corresponding one of said channels, said stop means comprising a number of teeth equally longitudinally spaced on each of said pillars, and said locking means comprising a plurality of bodily movable members associated with said pillars and manually shiftable into and out of engagement with the teeth of said pillars.
Claim 10
Dependent Claim
60 words
A machine as set forth in claim 7, wherein said moving means comprises a hydraulic cylinder secured to said frame and a piston operating in the cylinder and secured to said worktable, said guide channels being equidistant from said cylinder, and said bodily movable members being secured to a spider structure rotatably mounted on said frame coaxially with said cylinder.
