Abstract
A probe for use in measuring apparatus has a base member including a two-dimensional seat for an intermediate member which, in turn, includes a two-dimensional seat for a stylus holder. The two seats face in opposite directions so that the stylus holder can be displaced from the seated position in either of two opposite directions.
Claims18
A probe for use in measuring apparatus, comprising a housing having a first two-dimensional seat therein, an intermediate member in said housing, bias means connected between the housing and the intermediate member to urge the intermediate member into engagement with the first seat thereby to support the intermediate member on the first seat, in a rest position, the intermediate member being tiltable on, and being linearly separable from, the first seat when displaced from said rest position in opposition to the bias means, a second two-dimensional seat provided on the intermediate member and facing in a direction opposite to that in which the first seat faces, a stylus holder, a further bias means connected between the stylus holder and the intermediate member to urge the stylus holder into engagement with the second seat thereby to support the stylus holder on the second seat in a rest position, the stylus holder being tiltable on, and being linearly separable from, the second seat when displaced from said rest position in opposition to the further bias means, and means responsive to the separation of the intermediate member and stylus holder from said first and second seats, respectively.
A probe for use in measuring apparatus, comprising a base member having a first two-dimensional seat thereon, an intermediate member, bias means connected to the base member and the intermediate member to urge the intermediate member into engagement with the first seat thereby to support the intermediate member on the first seat in a rest position, the intermediate member being tiltable on, and being linearly separable from, the first seat when displaced from said rest position in opposition to the bias means, a second two-dimensional seat provided on the intermediate member and facing in a direction opposite to that in which the first seat faces, a stylus holder, a further bias means connected to the stylus holder and the intermediate member to urge the stylus holder into engagement with the second seat thereby to support the stylus holder on the second seat in a rest position, the stylus holder being tiltable on, and being linearly separable from, the second seat when displaced from said rest position in opposition to the further bias means, and means responsive to the separation of the intermediate member and stylus holder from said first and second seats, respectively.
