Abstract
Abstract A hand tool having a plurality of part-holding jaws which are operated from a remote handle through a shaft having a universal joint therein. The tool is capable of being used to hold a part in its jaws while that part is immersed in a very low temperature fluid such as liquid nitrogen. After the part has been thus chilled, the tool is capable of physically holding the chilled part while the part is moved to a different environment while maintaining the part in a chilled condition. The universal joint permits free rotational movement of the jaws with respect to the handle and also permits angular movement in the shaft of the tool. Tightening means are provided which permit holding the angular and rotational position of the jaws in a fixed position with respect to the handle.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
141 words
A device for angularly directing translational force which comprises: a first hollow shaft; a first central rod located within said first hollow shaft; a second hollow shaft connected at one end to said first hollow shaft; a second central rod located within said second hollow shaft and being operably connected at one end to said first central rod through a thrust pin and, at the junction of said first and second hollow shaft; hinge means for controllably permitting change of the angular relationship of said first and second hollow shaft and for controllably permitting rotation of said first hollow shaft about its longitudinal axis, said hinge means including tightening means which, in operation, simultaneously maintain the angular relation of said first and second hollow shafts, one to the other, and prevent rotation of said first hollow shaft about its longitudinal axis.
Claim 2
Independent Claim
141 words
A device for angularly directing translational force which comprises: a first hollow shaft; a first central rod located within said first hollow shaft; a second hollow shaft connected at one end to said first hollow shaft; a second central rod located within said second hollow shaft and being operably connected at one end to said first central rod through a thrust pin and, at the junction of said first and second hollow shaft; hinge means for controllably permitting change of the angular relationship of said first and second hollow shaft and for controllably permitting rotation of said first hollow shaft about its longitudinal axis, said hinge means including tightening means which, in operation, simultaneously maintain the angular relation of said first and second hollow shafts, one to the other, and prevent rotation of said first hollow shaft about its longitudinal axis.
Claim 3
Dependent Claim
99 words
The device of claim 1 wherein said hinge means comprise a slit collar for receiving one end of one of said hollow shafts and two arms extending from said slit collar toward the other of said hollow shafts, an end of said other shaft being received therebetween, and wherein actuation of said tightening means urges said arms toward one another and against the hollow shaft received therebetween to fix the angular relation of said shafts one with the other, said actuation simultaneously compressing said slit collar about the shaft received therein to prevent its rotation about its longitudinal axis.
Claim 4
Dependent Claim
78 words
A tool according to claim 2 having jaw means operable in response to translational movement of said first and second rods and thrust pin upon actuation of a remote handle, arms extending from the second end of said first hollow shaft distant from said hinge means embracing said jaw means when the latter are in a closed position, said jaw means being disengageable from the constraint of said arms upon actuation of the handle to prevent opening thereof.
Claim 5
Dependent Claim
23 words
The device of claim 2 wherein said thrust pin is connected to said first and second central rods through ball and socket joints.
Claim 6
Dependent Claim
78 words
A tool according to claim 1 having jaw means operable in response to translational movement of said first and second rods and thrust pin upon actuation of a remote handle, arms extending from the second end of said first hollow shaft distant from said hinge means embracing said jaw means when the latter are in a closed position, said jaw means being disengageable from the constraint of said arms upon actuation of the handle to prevent opening thereof.
Claim 7
Dependent Claim
23 words
The device of claim 1 wherein said thrust pin is connected to said first and second central rods through ball and socket joints.
Claim 8
Dependent Claim
176 words
A tool for angularly directing translational force which comprises: a first hollow shaft; a first central rod located within said first hollow shaft; a second hollow shaft connected at one end to said first hollow shaft; a second central rod located within said second hollow shaft and being operably connected at one end to said first central rod through a thrust pin and, at the junction of said first and second hollow shaft, hinge means for controllably permitting change of the angular relationship of said first and second hollow shaft and for controllably permitting rotation of said first hollow shaft about its longitudinal axis, and jaw means operable in response to translational movement of said first and second rods and thrust pins upon actuation of a remote handle, arms extending from the second end of said first hollow shaft distant from said hinge means embracing said jaw means when the latter are in a closed position, said jaw means being disengageable from the constraint oF said arms upon actuation of the handle to prevent opening thereof.
Claim 9
Dependent Claim
176 words
A tool for angularly directing translational force which comprises: a first hollow shaft; a first central rod located within said first hollow shaft; a second hollow shaft connected at one end to said first hollow shaft; a second central rod located within said second hollow shaft and being operably connected at one end to said first central rod through a thrust pin and, at the junction of said first and second hollow shaft, hinge means for controllably permitting change of the angular relationship of said first and second hollow shaft and for controllably permitting rotation of said first hollow shaft about its longitudinal axis, and jaw means operable in response to translational movement of said first and second rods and thrust pins upon actuation of a remote handle, arms extending from the second end of said first hollow shaft distant from said hinge means embracing said jaw means when the latter are in a closed position, said jaw means being disengageable from the constraint oF said arms upon actuation of the handle to prevent opening thereof.
Claim 10
Dependent Claim
23 words
The tool of claim 7 wherein said thrust pin is connected to said first and second central rods through ball and socket joints.
Claim 11
Independent Claim
121 words
A device for angularly directing translational force which comprises: a first hollow shaft; a first central rod located within said first hollow shaft; a second hollow shaft connected at one end to said first hollow shaft; a second central rod located within said second hollow shaft and being operably connected at one end to said first central rod through a thrust pin, such thrust pin being connected to said first and second central rods through ball and socket joints and, at the junction of said first and second hollow shaft, hinge means for controllably permitting change of the angular relationship of said first and second hollow shaft and for controllably permitting rotation of said first hollow shaft about its longitudinal axis.
Claim 12
Independent Claim
121 words
A device for angularly directing translational force which comprises: a first hollow shaft; a first central rod located within said first hollow shaft; a second hollow shaft connected at one end to said first hollow shaft; a second central rod located within said second hollow shaft and being operably connected at one end to said first central rod through a thrust pin, such thrust pin being connected to said first and second central rods through ball and socket joints and, at the junction of said first and second hollow shaft, hinge means for controllably permitting change of the angular relationship of said first and second hollow shaft and for controllably permitting rotation of said first hollow shaft about its longitudinal axis.
