Abstract
Abstract Gaging apparatus in which workpieces to be gaged are continuously conveyed along a predetermined path, with an endless series of gage members movable along at least a portion of this path in unison with the workpieces. The gage members are brought into engagement with the workpieces as they travel along the stated portion of the path, and sensor actuators on the gage members pass by a proximity sensor with a gap between the sensor actuators and the sensor, the extent of the gap being determined by the workpiece. The sensor is responsive to the passage of each actuator to transmit a signal related to the extent of the gap between the actuator and the sensor, thereby to gage the gap and hence the workpiece.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
155 words
Gaging apparatus comprising a proximity sensor mounted in fixed position at a gaging station, means for continuously conveying units one after another through said station past the sensor with a gap between the units and the sensor, said sensor being responsive to passage of each unit in proximity to the sensor to gage the gap between the unit and the sensor, and means for continuously conveying workpieces to be gaged one after another in a predetermined path through said station, wherein said units are gage members and said means for conveying the latter comprises an endless conveyor carrying said gage members and means for moving said gage member conveyor in an endless path at least part of which parallels the path of the workpiece conveyor through the gaging station with the gage members contacting the workpieces as they pass through the gaging station, said gaging members carrying means for passage in proximity to the sensor.
Claim 2
Dependent Claim
155 words
Gaging apparatus comprising a proximity sensor mounted in fixed position at a gaging station, means for continuously conveying units one after another through said station past the sensor with a gap between the units and the sensor, said sensor being responsive to passage of each unit in proximity to the sensor to gage the gap between the unit and the sensor, and means for continuously conveying workpieces to be gaged one after another in a predetermined path through said station, wherein said units are gage members and said means for conveying the latter comprises an endless conveyor carrying said gage members and means for moving said gage member conveyor in an endless path at least part of which parallels the path of the workpiece conveyor through the gaging station with the gage members contacting the workpieces as they pass through the gaging station, said gaging members carrying means for passage in proximity to the sensor.
Claim 3
Dependent Claim
37 words
Apparatus as set forth in claim 1 having means backing the workpieces and constituting a datum reference for the workpieces as they pass through the gaging station for gaging the gap in relation to the datum reference.
Claim 4
Dependent Claim
57 words
Apparatus as set forth in claim 1 wherein said gage members are carried by the gage member conveyor for movement from a retracted position into engagement with the workpieces, and wherein means is provided for moving the gage members into engagement with the workpieces as they pass through the gaging station and then retracting the gage members.
Claim 5
Dependent Claim
83 words
Apparatus as set forth in claim 3 wherein the gage member conveyor comprises a wheel rotatable on a vertical axis, the gage members being arranged in a circular series around the wheel, the workpiece conveyor conveying the workpieces in a part-circular path through the gaging station below the circle of the gage members, and the gage members being movable downward relative to the wheel into engagement with workpieces travelling therebelow as they pass through the gaging station and then upward to retracted position.
Claim 6
Dependent Claim
49 words
Gaging apparatus as set forth in claim 4 wherein the sensor is mounted in fixed position above the wheel at the gaging station, and the said proximity means on each gage member comprises an armature on the gage member adapted to pass over the sensor with said gap therebetween.
Claim 7
Dependent Claim
80 words
Gaging apparatus as set forth in claim 5 wherein the workpiece conveyor comprises an endless chain having links connected by tubular pins, the workpieces being received in the pins, the chain being trained around a sprocket coaxial with and below the wheel and rotary with the wheel, and the apparatus having means for supporting the workpieces at the bottom as they travel around with the chain through the gaging station establishing a datum reference for the gaging of the gap.
Claim 8
Dependent Claim
20 words
Gaging apparatus as set forth in claim 6 having means for entering workpieces in the tubular pins of said chain.
Claim 9
Dependent Claim
36 words
Gaging apparatus as set forth in claim 7 wherein said entering means inserts the workpieces into the pins through the lower ends of the pins, the workpieces being then supported by said datum reference supporting means.
Claim 10
Dependent Claim
103 words
Gaging apparatus as set forth in claim 8 wherein said entering means comprises an endless delivery chain having links connected by tubular pins, the workpieces being received in these pins, the said delivery chain being trained around a second sprocket coaxial with and below the first-mentioned sprocket and rotary with the latter, a second wheel rotary with the second sprocket and below the latter, a circular series of lift pins carried by the second wheel, and means for moving the lift pins to push workpieces upwardly out of the pins of the delivery chain into the pins of the workpiece conveyor chain thereabove.
Claim 11
Dependent Claim
36 words
Gaging apparatus as set forth in claim 9 wherein said datum reference supporting means comprises a circular plate rotatable with the sprockets between the sprockets and eccentrically mounted with respect to the axis of the sprockets.
Claim 12
Dependent Claim
49 words
Gaging apparatus as set forth in claim 5 wherein the means for moving the gage members up and down comprises a fixed cylindrical cam at the periphery of a circular plate mounted in fixed position above said wheel, the sensor being mounted on this plate at the gaging station.
Claim 13
Dependent Claim
36 words
Gaging apparatus as set forth in claim 11 wherein each gage member is carried by a holder movable up and down by the cam, and spring means is provided between the holder and the gage member.
