Abstract
Abstract An aquatic depth control device for connection to trolling fishlines to submerge such lines when trolled but responsive to increased tension to change in orientation and attitude to terminate the submerging force. The device includes a channelshaped body of the light metal, a pin member which is releasably engaged laterally between the side portions of the channel-shaped body to receive a towline and a connector extending between the pin member and a forward point on the body such that when the pin member is released due to increased towline tension, the tow point changes location on the body to permit the change in orientation and attitude.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
137 words
An aquatic depth control device comprising a light body having a substantially straight bottom portion and sidewalls and being adapted to react against water passing therethrough when in one orientation, connector means extending between first and second spaced points forwardly on the body and adapted to receive a towline adjacent one end thereof, means disposed rearwardly on the body for connection to a towed line, means releasably securing the connector means adjacent said one end between the sidewalls at one of the spaced points to tow the body from said one point in said orientation and responsive to a predetermined tension in the towline to release the connector means from between the sidewalls to thereafter tow the body from the other of the sPaced points thereby to vary the orientation of the body relative to the towline.
Claim 2
Dependent Claim
137 words
An aquatic depth control device comprising a light body having a substantially straight bottom portion and sidewalls and being adapted to react against water passing therethrough when in one orientation, connector means extending between first and second spaced points forwardly on the body and adapted to receive a towline adjacent one end thereof, means disposed rearwardly on the body for connection to a towed line, means releasably securing the connector means adjacent said one end between the sidewalls at one of the spaced points to tow the body from said one point in said orientation and responsive to a predetermined tension in the towline to release the connector means from between the sidewalls to thereafter tow the body from the other of the sPaced points thereby to vary the orientation of the body relative to the towline.
Claim 3
Dependent Claim
28 words
A device as defined in claim 1 wherein each of the sidewalls comprises an arcuate leading edge and a trailing edge which tapers rearwardly toward the bottom portion.
Claim 4
Dependent Claim
42 words
A device as defined in claim 2 wherein the means releasably securing the connector means comprises a pin member pivotally connected to the connector means and adapted to be frictionally engaged laterally between the sidewalls at said one of the spaced points.
Claim 5
Dependent Claim
25 words
A device as defined in claim 3 wherein each of the sidewalls has formed therein an indentation for receiving and releasably securing the pin member.
Claim 6
Dependent Claim
23 words
A device as defined in claim 4 wherein the body is formed of a single piece of light noncorrosive metal such as aluminum.
Claim 7
Dependent Claim
79 words
A device as set forth in claim 4 wherein the connector means is pivotally connected on said one end to the pin member and on the other end to the bottom portion and said one point is mediate the sidewalls and spaced from the bottom portion whereby the body assumes a submerging orientation with the sidewalls generally upstanding when towed from the one point and a substantially level orientation with the sidewalls inverted when towed from the second point.
Claim 8
Dependent Claim
44 words
A device as defined in claim 6 wherein the bottom and sidewalls are formed of a light, deformable material to permit variation in the spacing between the sidewalls thereby to adjust the predetermined tension in the towline which causes release of the pin member.
Claim 9
Dependent Claim
27 words
A device as defined in claim 1 wherein the body has holes formed therein adjacent the front and rear edges thereof and rings disposed through the holes.
