Abstract
Abstract A progressive die sensor of the disclosure for sensing an unaligned workpiece condition includes a housing having an upper mounting surface engaged with an upper punch holder during mounting. A depression in the mounting surface is located in a spaced relationship to a downwardly extending probe that moves relative to the housing to indicate an unaligned workpiece condition. A switch received within the depression includes an actuating plunger that is moved by a push rod in response to the probe movement to cause switch actuation for generating an electrical signal which indicates the occurrence of the unaligned workpiece condition. A switch cover is received within the depression to cover the switch. The housing depression preferably opens upwardly and the switch cover includes downwardly extending side portions that receive the switch therebetween intermediate opposite sides of the switch depression. Between its opposite sides, the depression preferably has a rectangular cross section that is closed by the side portions of the cover. Positioning posts mounted on the cover locate the switch within the depression against relative movement with respect to the housing. A gasket engages the side portions of the cover to provide sealing of the depression.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
243 words
A progressive die sensor comprising: a housing for mounting on an upper punch holder; said housing including opposite side surfaces and an upper mounting surface that engages the upper punch holder when the housing is mounted thereon; a depression that opens upwardly in the housing along the mounting surface thereof and has opposite sides opening to the side surfaces of the housing and a rectangular cross section therebetween; means for mounting a downwardly extending probe on the housing in a spaced relationship from the depression for relative movement that indicates an unaligned workpiece condition; a switch received within the depression and including an actuating plunger; a switch cover secured within the housing depression and having downwardly extending side portions of rectangular cross sections between which the switch is received; said switch cover including an upper surface that defines a continuation of the upper mounting surface of the housing and which engages the punch holder along with the housing mounting surface during mounting thereon; said side portions of the switch cover including surfaces that form a continuation of the housing side surfaces at the opposite sides of the depression; means for positioning the switch with respect to the housing and the cover in the depression; and a push rod extending between the probe and the switch plunger to actuate the switch in response to probe movement indicating an unaligned workpiece condition such that an electrical signal may be generated when such a condition occurs.
Claim 2
Dependent Claim
243 words
A progressive die sensor comprising: a housing for mounting on an upper punch holder; said housing including opposite side surfaces and an upper mounting surface that engages the upper punch holder when the housing is mounted thereon; a depression that opens upwardly in the housing along the mounting surface thereof and has opposite sides opening to the side surfaces of the housing and a rectangular cross section therebetween; means for mounting a downwardly extending probe on the housing in a spaced relationship from the depression for relative movement that indicates an unaligned workpiece condition; a switch received within the depression and including an actuating plunger; a switch cover secured within the housing depression and having downwardly extending side portions of rectangular cross sections between which the switch is received; said switch cover including an upper surface that defines a continuation of the upper mounting surface of the housing and which engages the punch holder along with the housing mounting surface during mounting thereon; said side portions of the switch cover including surfaces that form a continuation of the housing side surfaces at the opposite sides of the depression; means for positioning the switch with respect to the housing and the cover in the depression; and a push rod extending between the probe and the switch plunger to actuate the switch in response to probe movement indicating an unaligned workpiece condition such that an electrical signal may be generated when such a condition occurs.
Claim 3
Dependent Claim
201 words
A sensor comprising: a housing for mounting on an upper punch holder; said housing including lateral side surfaces and an upper mounting surface that engages the upper punch holder when the housing is mounted thereon; an upwardly opening depression in the housing that has opposite sides opening to the lateral side surfaces of the housing; means for mounting a downwardly extending probe on the housing in a spaced relationship from the depression for relative movement that indicates an unaligned workpiece condition; a switch received within the depression and including an actuating plunger; a switch cover secured within the housing depression to cover the switch; the switch cover including downwardly extending side portions adjacent the opposite sides of the depression; said side portions being spaced with respect to each other to receive the switch therebetween; posts that extend between the switch and the cover intermediate the downwardly extending cover side portions to position the switch with respect to the housing and the switch cover; a push rod extending between the probe and the switch plunger to actuate the switch in response to probe movement indicating an unaligned workpiece condition such that an electrical signal may be generated when such a condition occurs.
Claim 4
Dependent Claim
201 words
A sensor comprising: a housing for mounting on an upper punch holder; said housing including lateral side surfaces and an upper mounting surface that engages the upper punch holder when the housing is mounted thereon; an upwardly opening depression in the housing that has opposite sides opening to the lateral side surfaces of the housing; means for mounting a downwardly extending probe on the housing in a spaced relationship from the depression for relative movement that indicates an unaligned workpiece condition; a switch received within the depression and including an actuating plunger; a switch cover secured within the housing depression to cover the switch; the switch cover including downwardly extending side portions adjacent the opposite sides of the depression; said side portions being spaced with respect to each other to receive the switch therebetween; posts that extend between the switch and the cover intermediate the downwardly extending cover side portions to position the switch with respect to the housing and the switch cover; a push rod extending between the probe and the switch plunger to actuate the switch in response to probe movement indicating an unaligned workpiece condition such that an electrical signal may be generated when such a condition occurs.
Claim 5
Dependent Claim
39 words
A sensor as in claim 2 wherein the depression in the housing has a rectangular cross section between the opposite sides thereof, and the side portions of the cover having rectangular shapes closing the opposite sides of the depression.
Claim 6
Dependent Claim
27 words
A sensor as in claim 3 further including a gasket that seals between the side portions of the cover and the opposite sides of the housing depression.
Claim 7
Dependent Claim
30 words
A sensor as in claim 3 wherein the housing includes a push rod hole receiving the push rod and opening to the depression between the side portions of the cover.
Claim 8
Dependent Claim
37 words
A sensor as in claim 5 wherein the push rod includes an annular flange, the push rod hole in the housing including a seat; and a spring for normally engaging the push rod flange with the seat.
Claim 9
Dependent Claim
58 words
A sensor as in claim 2 wherein the housing includes a rounded end that mounts the probe and a squared end having an electrical cable hole that communicates with the depression and the environment to allow a cable to be connected to the switch and to carry an electrical signal from the switch indicating an unaligned workpiece condition.
