Abstract
Abstract A device designed to travel through water at any of a plurality of depths by means of being towed from a conventional water craft wherein the device may be utilized as a sinker to maintain fishing tackle at a desired depth or as a transporter vehicle for transporting fluids, or the like, beneath the surface of the water. A towline is connected to the device such that the point of attachment of the towline to the device may be readily adjusted. The position of the attach point determines the angular orientation of the device relative to the direction of travel and consequently the effective downward force produced by the device. Fins extend outwardly from a hollow body and provide attitude stabilization as the device travels through water. A diaphragm arranged within the body defines an internal compartment in which fluid could be transported. Pressure equalization means in the form of vents equalize the pressure between the interior and exterior of the body thereby eliminating external static pressure considerations from the structural design and consequently allowing the device to travel at the desired depth.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
191 words
A device of the type designed to travel through water in a towed fashion, said device comprising: a. a body including a hollow interior portion; b. attitude stabilizing means fixedly attached to said body and including a deck portion extending laterally outward from said body; c. means on said stabilizing means to adjustably position an attach point of a tow line attached to said device at predetermined positions along said deck portion, wherein the depth at which said device travels is thereby determined; d. pressure equalizing means positioned in communicating relation with said hollow interior portion of said body, whereby fluid is allowed to pass into and out of said body interior in such a manner as to equalize the interior and exterior pressures on Said body; and e. said pressure equalizing means including at least two holes arranged in communicating relation with said interior of said body in spaced relation to one another, whereby water passes into the interior of said body through one of said holes and air passes out of said interior through the other of said holes until the pressure inside and outside the body is equalized.
Claim 2
Independent Claim
191 words
A device of the type designed to travel through water in a towed fashion, said device comprising: a. a body including a hollow interior portion; b. attitude stabilizing means fixedly attached to said body and including a deck portion extending laterally outward from said body; c. means on said stabilizing means to adjustably position an attach point of a tow line attached to said device at predetermined positions along said deck portion, wherein the depth at which said device travels is thereby determined; d. pressure equalizing means positioned in communicating relation with said hollow interior portion of said body, whereby fluid is allowed to pass into and out of said body interior in such a manner as to equalize the interior and exterior pressures on Said body; and e. said pressure equalizing means including at least two holes arranged in communicating relation with said interior of said body in spaced relation to one another, whereby water passes into the interior of said body through one of said holes and air passes out of said interior through the other of said holes until the pressure inside and outside the body is equalized.
Claim 3
Dependent Claim
58 words
A device as in claim 1 wherein said means to position said attach point comprises: a cam surface arranged on said stabilizing means along the longitudinal center of said body, whereby the position of said attach point along said surface determines the angular orientation of said body relative to the direction of travel of said device through water.
Claim 4
Dependent Claim
54 words
A device as in claim 2 wherein said cam surface includes a substantially curved portion and a substantially linear portion, said curved portion arranged relative to said body such that positioning of said attach point on said curved portion establishes an angular orientation of said device to the direction of travel of said device.
Claim 5
Dependent Claim
51 words
A device as in claim 2 wherein said attitude stabilizing means further includes at least one fin extending generally parallel to the longitudinal axis of said body; said cam surface being arranged on said fin such that a towline attached to said device is free to travel along said cam surface.
Claim 6
Dependent Claim
108 words
A device as in claim 1 wherein said attitude stabilizing means further includes at least one fin extending long a direction substantially parallel to the longitudinal axis of said body; said means to position said attach point comprising an elongated slot disposed on said fin; said slot comprising a first portion extending toward the front of the device and a second portion disposed at an angular relation to said first portion and extending toward the rear of the device; whereby the position of said attach point along either said first or second portion determines the attitude of said device relative to the direction of travel of said device.
Claim 7
Dependent Claim
39 words
A device as in claim 5 wherein said second portion has a curved configuration such that the position of said attach point along said curved portion establishes an angular orientation of said device relative to the direction of travel.
Claim 8
Dependent Claim
34 words
A device as in claim 5 further comprising a stop means mounted on said second portion so as to prohibit the attach point from being positioned on a predetermined area of said second portion.
Claim 9
Dependent Claim
36 words
A device as in claim 1 further comprising means mounted within said interior to define at least one fluid carrying compartment within said interior, said compartment arranged in substantially isolated relation to said pressure equalizing means.
Claim 10
Dependent Claim
15 words
A device as in claim 8 wherein said compartment defining means comprises a flexible diaphragm.
Claim 11
Dependent Claim
32 words
A device as in claim 1 wherein said means to position said attach point comprises: an adjustable screw attached to said deck, and means to movably attach said towline to said screw.
Claim 12
Independent Claim
194 words
A device of the type designed to travel through water in a towed fashion, said device comprising: a. a body including a hollow interior portion; b. attitude stabilizing means fixedly connected to said body, including a deck portion extending laterally outward from said body; c. means on said deck portion of said body to adjustably position an attach point of a tow line attached to said device, whereby the angular orientation of said device is thereby determined; d. means mounted within said hollow interior to define a compartment, whereby material may be stored within said compartment during travel of said device through water; e. pressure equalization means arranged in noncommunicating relation with said compartment, whereby pressure on the exterior and interior of said body may be equalized to allow submersion of said device; f. said pressure equalization means comprising a valve means disposed in communicating relation to a portion of said interior separated froM said compartment by said compartment defining means; and g. said valve means comprising an air valve located in the approximate stern of said body and a water inlet valve positioned in front of said interior portion separated from said compartment.
Claim 13
Independent Claim
194 words
A device of the type designed to travel through water in a towed fashion, said device comprising: a. a body including a hollow interior portion; b. attitude stabilizing means fixedly connected to said body, including a deck portion extending laterally outward from said body; c. means on said deck portion of said body to adjustably position an attach point of a tow line attached to said device, whereby the angular orientation of said device is thereby determined; d. means mounted within said hollow interior to define a compartment, whereby material may be stored within said compartment during travel of said device through water; e. pressure equalization means arranged in noncommunicating relation with said compartment, whereby pressure on the exterior and interior of said body may be equalized to allow submersion of said device; f. said pressure equalization means comprising a valve means disposed in communicating relation to a portion of said interior separated froM said compartment by said compartment defining means; and g. said valve means comprising an air valve located in the approximate stern of said body and a water inlet valve positioned in front of said interior portion separated from said compartment.
