Abstract
Abstract A probe for mounting a transducer, and having a hole extending longitudinal therethrough for a lead, is formed of two end portions having facing intermeshing bevel gears disposed with axes that are at an angle to the axis of the respective end portions. A central portion is mounted to the two end portions for rotation with respect thereto for holding the bevel gears in contact with one another.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
129 words
In a probe including an elongated body adapted to receive a transducer at one end and having a central bore for leading conductor means from said transducer through the other end thereof, the improvement wherein said body comprises first and second hollow probe end members and a hollow central probe member, said end members each having a bevel gear non-rotatably affixed to a first end thereof, said first ends being directed toward one another with the bevel gears intermeshing, the axes of the gears being at fixed acute angles to the axes of said respective end members, said central probe member being rotatably mounted to each of said end members surrounding said gears for inhibiting relative separation of said gears, and adjusting the relative angle of said end portions.
Claim 2
Dependent Claim
129 words
In a probe including an elongated body adapted to receive a transducer at one end and having a central bore for leading conductor means from said transducer through the other end thereof, the improvement wherein said body comprises first and second hollow probe end members and a hollow central probe member, said end members each having a bevel gear non-rotatably affixed to a first end thereof, said first ends being directed toward one another with the bevel gears intermeshing, the axes of the gears being at fixed acute angles to the axes of said respective end members, said central probe member being rotatably mounted to each of said end members surrounding said gears for inhibiting relative separation of said gears, and adjusting the relative angle of said end portions.
Claim 3
Dependent Claim
60 words
The probe of claim 1 wherein said end members are generally tubular, with the respective bevel gears defining the ends of tubular portions of reduced diameter, whereby the portions of reduced diameter define shoulders at an angle to the axis of the respective end member, said central member rotatably surrounding said reduced diameter portions and having ends abutting said shoulders.
Claim 4
Dependent Claim
62 words
The probe of claim 1 wherein each of said end members has, on one end thereof, a tubular projection extending at an angle to the remainder of the end member and defining a shoulder extending radially outwardly from the tubular projection to the remainder of the respective end member, said bevel gears being formed on the free ends of said tubular projections.
Claim 5
Dependent Claim
26 words
The probe of claim 3 wherein said central member rotatably surrounds the tubular projections of said end members and has end surfaces slidably engaging said shoulder.
Claim 6
Dependent Claim
38 words
The probe of claim 1 wherein the bevel gears differ in alignment by one-half gear pitch with respect to the plane defined by the axis of the respective end members and the axis of the respective bevel gear.
Claim 7
Dependent Claim
108 words
In a probe including an elongated body adapted to receive a transducer at one end having a central bore for leading conductor means from said transducer through the other end thereof, the improvement wherein said body comprises first and second end members and a central member, said end members having bevel gears directed toward and engaging one another, with the axis of at least one bevel gear being non-parallel to the axis of the respective end member, said central member being rotatably mounted to each of said end members surrounding said gears for inhibiting relative separation of said gears, and adjusting the relative angle of said end members.
Claim 8
Dependent Claim
108 words
In a probe including an elongated body adapted to receive a transducer at one end having a central bore for leading conductor means from said transducer through the other end thereof, the improvement wherein said body comprises first and second end members and a central member, said end members having bevel gears directed toward and engaging one another, with the axis of at least one bevel gear being non-parallel to the axis of the respective end member, said central member being rotatably mounted to each of said end members surrounding said gears for inhibiting relative separation of said gears, and adjusting the relative angle of said end members.
