Abstract
Abstract A device for holding a test head, especially a head for ultrasonic testing in which a resiliently extensible but nonrotatable beam structure has one part connected to a support, while at the free end of the beam there is a yoke to which a cardanic holding member is pivotally connected on a first axis which is perpendicular to the longitudinal axis of the beam and with the holding member adapted for supporting the test head on an axis perpendicular to the axis of the beam and also perpendicular to the axis on which the holding member is pivoted to the yoke.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
170 words
A device for holding a testing head, especially an ultrasonic testing head, comprising: a beam having a first axial member adapted for connection to a support and a second axial member moveable relative to said first member along the axis of the beam, said second member having a free end remote from said first member, a yoke fixed to the free end of said second member, a holding member, first means supporting said holding member on said yoke for pivotal movement of said holding member about a first axis, second means on said holding member for supporting a testing head thereon for pivotal movement of the testing head about a second axis disposed at an angle to said first axis, and a spring acting between said first and second axial members and urging the said first and second axial members apart toward a position of maximum elongation of said beam, said spring having a substantially flat characteristic over the range of relative adjustability of said first and second axial members.
Claim 2
Independent Claim
170 words
A device for holding a testing head, especially an ultrasonic testing head, comprising: a beam having a first axial member adapted for connection to a support and a second axial member moveable relative to said first member along the axis of the beam, said second member having a free end remote from said first member, a yoke fixed to the free end of said second member, a holding member, first means supporting said holding member on said yoke for pivotal movement of said holding member about a first axis, second means on said holding member for supporting a testing head thereon for pivotal movement of the testing head about a second axis disposed at an angle to said first axis, and a spring acting between said first and second axial members and urging the said first and second axial members apart toward a position of maximum elongation of said beam, said spring having a substantially flat characteristic over the range of relative adjustability of said first and second axial members.
Claim 3
Independent Claim
200 words
A device for holding a testing head, especially an ultrasonic testing head, comprising: a beam having a first axial member adapted for connection to a support and a second axial member moveable relative to said first member along the axis of the beam, said second member having a free end remote from said first member, a yoke fixed to the free end of said second member, a holding member, first means supporting said holding member on said yoke for pivotal movement of said holding member about a first axis, and second means on said holding member for supporting a testing head thereon for pivotal movement of the testing head about a second axis disposed at an angle to said first axis, said first axial member being in the form of a first length of pipe, said second axial member being in the form of a second length of pipe and telescopically engaging the inside of said first length of pipe, a support to which said first length of pipe is nonrotatably connected, and means on one of said first length of pipe and said support engaging said second length of pipe and preventing rotation thereof while permitting axial movement thereof.
Claim 4
Independent Claim
200 words
A device for holding a testing head, especially an ultrasonic testing head, comprising: a beam having a first axial member adapted for connection to a support and a second axial member moveable relative to said first member along the axis of the beam, said second member having a free end remote from said first member, a yoke fixed to the free end of said second member, a holding member, first means supporting said holding member on said yoke for pivotal movement of said holding member about a first axis, and second means on said holding member for supporting a testing head thereon for pivotal movement of the testing head about a second axis disposed at an angle to said first axis, said first axial member being in the form of a first length of pipe, said second axial member being in the form of a second length of pipe and telescopically engaging the inside of said first length of pipe, a support to which said first length of pipe is nonrotatably connected, and means on one of said first length of pipe and said support engaging said second length of pipe and preventing rotation thereof while permitting axial movement thereof.
Claim 5
Dependent Claim
43 words
A device according to claim 2 which includes a guide rod fixed to said first length of pipe and extending axially in said first and second lengths of pipe, said spring being disposed radially between said rod and said second length of pipe.
Claim 6
Dependent Claim
24 words
A device according to claim 2 which includes antifriction bearing means radially guiding said second length of pipe on said first length of pipe.
Claim 7
Dependent Claim
26 words
A device according to claim 4 in which said antifriction bearing means are disposed in circumferentially spaced relation between said first and second lengths of pipe.
Claim 8
Dependent Claim
37 words
A device according to claim 2 in which said means preventing rotation of said second length of pipe comprises an elongated axial key thereon, and stationarily mounted bearing means engaging the circumferentially opposite sides of said key.
