Abstract
Abstract A submergible chamber is provided with flanges at the outward ends of chamber guide arms, wherein each flange engages a stanchion. In one embodiment the flanges are selectively electromagnetic with the stanchions, and with sufficient force, the flanges are held to the stanchions thereby positioning the chamber at a specific depth. In another embodiment, the flange is adapted to pivotally grip the stanchion, and further each stanchion is provided with a vertical gear rack engaging the driven gear of each respective work arm so as to accurately position the chamber at a specific depth whereat the clamp holds the chamber at that depth.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
134 words
A guide arm clamp for a submergible chamber comprising a flange, means to mount said flange to a work arm of the submergible chamber, said flange being formed so as to be engageable, when submerged, with a submerged, positioned guide bar, and means on said flange to permit sliding engagement with the guide bar in a first mode, and means on said flange to hold the clamp to the guide bar to prevent sliding in a second mode further comprising roller means mounted to the flange and extending away from the flange surface so as to contact the guide bar, means to retract the roller means in the second mode, whereby in the first mode the roller means slidingly engages the guide bar and in a second mode the flange contacts the guide bar.
Claim 2
Dependent Claim
134 words
A guide arm clamp for a submergible chamber comprising a flange, means to mount said flange to a work arm of the submergible chamber, said flange being formed so as to be engageable, when submerged, with a submerged, positioned guide bar, and means on said flange to permit sliding engagement with the guide bar in a first mode, and means on said flange to hold the clamp to the guide bar to prevent sliding in a second mode further comprising roller means mounted to the flange and extending away from the flange surface so as to contact the guide bar, means to retract the roller means in the second mode, whereby in the first mode the roller means slidingly engages the guide bar and in a second mode the flange contacts the guide bar.
Claim 3
Dependent Claim
40 words
The guide arm clamp of claim 1, said holding means comprises means mounted in said flange to provide an electromagnetic force between the flange and the guide bar, and said flange and guide bar being responsive to the electromagnetic force.
Claim 4
Dependent Claim
48 words
The guide arm clamp of claim 2, wherein the guide bar is a stanchion, wherein the guide arm clamp is movable transverse to the axis of the stanchion, so that in going from the first mode to the second mode the flange moves into contact with the stanchion.
Claim 5
Dependent Claim
42 words
The guide arm clamp of claim 1, said clamp being rotatable in relation to said work arm further comprising means mounted between said work arm and flange to rotate the clamp about an axis transverse to the axis of the guide bar.
Claim 6
Dependent Claim
36 words
The guide arm clamp of claim 1, wherein the roller means comprises a plurality of balls mounted in the flange, and wherein said means to retract comprises spring means disposed between the balls and the flange,
Claim 7
Dependent Claim
33 words
The guide arm clamp of claim 2, further comprises means to operably connect the electromagnetic force means to the submergible chamber, so that the electromagnetic force can be controlled from within the chamber.
Claim 8
Dependent Claim
28 words
The guide arm clamp of claim 1, wherein said flange has a radius of curvature so as to engage a complimentary radius of curvature of said guide bar.
Claim 9
Dependent Claim
22 words
The guide arm clamp of claim 7, wherein said flange is part cylindrical and wherein said guide bar is cylindrical in section.
Claim 10
Dependent Claim
12 words
The guide arm clamp of claim 5, wherein the balls are non-magnetic.
Claim 11
Dependent Claim
15 words
The guide arm clamp of claim 9, wherein the surface of said balls is Teflon.
Claim 12
Dependent Claim
93 words
A guide arm clamp for a submergible chamber comprising a flange, means to mount said flange to a work arm of a submergible chamber, said flange being formed so as to be engageable, when submerged, with a submerged, positioned guide bar, and means on said flange to permit movement along the guide bar, drive means comprising a gear mounted on said clamp and means to rotate the gear, said gear being engageable with a gear rack on said guide bar, whereby said driven gear provides movement of said clamp along said guide bar.
Claim 13
Dependent Claim
93 words
A guide arm clamp for a submergible chamber comprising a flange, means to mount said flange to a work arm of a submergible chamber, said flange being formed so as to be engageable, when submerged, with a submerged, positioned guide bar, and means on said flange to permit movement along the guide bar, drive means comprising a gear mounted on said clamp and means to rotate the gear, said gear being engageable with a gear rack on said guide bar, whereby said driven gear provides movement of said clamp along said guide bar.
Claim 14
Dependent Claim
54 words
The guide arm clamp of claim 11, means to pivot said flange to said clamp, and wherein said first mode the flange is pivoted to a first position to permit sliding engagement with the guide bar, and wherein said second mode the flange is pivoted to a second position to contact said guide bar.
Claim 15
Dependent Claim
21 words
The guide arm clamp of claim 12, said clamp further comprising drive means to move the clamp along the guide bar.
Claim 16
Dependent Claim
33 words
The guide arm clamp of claim 12, wherein said means to pivot comprises a cylinder with a retractably extensible ram and wherein the outward end of the ram is connected to the flange.
Claim 17
Dependent Claim
36 words
The guide arm clamp of claim 11, said drive means further comprising a gear mounted on said clamp and means to rotate the gear, said gear being engageable with a gear rack on said guide bar.
Claim 18
Dependent Claim
132 words
A guide arm clamp for a submergible chamber comprising a flange, means to mount said flange to a work arm of a submergible chamber, said flange being formed so as to slidably engage a submerged positioned guide bar, means operatively mounted with said clamp and work arm to move said clamp relative to said work arm, whereby in a first mode said flange is spaced from and in sliding engagement with said guide bar and in said second mode said clamp movement means causes said flange to contact said guide bar, means mounted in said flange to provide an electromagnetic force between the flange and the guide bar, said flange and guide bar being responsive to the electromagnetic force, whereby the flange is held to the guide bar in said second mode.
Claim 19
Dependent Claim
132 words
A guide arm clamp for a submergible chamber comprising a flange, means to mount said flange to a work arm of a submergible chamber, said flange being formed so as to slidably engage a submerged positioned guide bar, means operatively mounted with said clamp and work arm to move said clamp relative to said work arm, whereby in a first mode said flange is spaced from and in sliding engagement with said guide bar and in said second mode said clamp movement means causes said flange to contact said guide bar, means mounted in said flange to provide an electromagnetic force between the flange and the guide bar, said flange and guide bar being responsive to the electromagnetic force, whereby the flange is held to the guide bar in said second mode.
