Abstract
Abstract A method and apparatus for reproducing in minute detail a surface underwater. The apparatus consists of a layer of wax supported in a frame for movement into and out of contact with the surface to be reproduced, there being provided means for heating wax material to soften it and means for withdrawing the water from between the wax and surface to be molded to provide a substantially water free surface for molding.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
85 words
A method of replicating an underwater surface of a ship comprising the steps of: positioning a container of thermo-plastic replicating material adjacent the underwater surface to be replicated withdrawing the water from between the replicating material and the surface; heating the replicating material to its softening point; applying pressure of the ambient water to force the replicating material against the surface; cooling the replicating material to harden it; and withdrawing the replicating material containing the negative image of the surface from contact with the surface.
Claim 2
Independent Claim
85 words
A method of replicating an underwater surface of a ship comprising the steps of: positioning a container of thermo-plastic replicating material adjacent the underwater surface to be replicated withdrawing the water from between the replicating material and the surface; heating the replicating material to its softening point; applying pressure of the ambient water to force the replicating material against the surface; cooling the replicating material to harden it; and withdrawing the replicating material containing the negative image of the surface from contact with the surface.
Claim 3
Dependent Claim
30 words
A method as claimed in claim 1 in which the step of withdrawing the water includes the blowing of air over the surface to complete the removal of the water.
Claim 4
Dependent Claim
69 words
An underwater replicating device comprising: a housing for underwater attachment to a surface to be replicated; first means within said housing for obtaining the impression of a surface being replicated; second means for sealing said housing against the intrusion of the ambient water while the first means is applied underwater to the surface being replicated; and means for releasing said device together with the first means from the surface.
Claim 5
Dependent Claim
69 words
An underwater replicating device comprising: a housing for underwater attachment to a surface to be replicated; first means within said housing for obtaining the impression of a surface being replicated; second means for sealing said housing against the intrusion of the ambient water while the first means is applied underwater to the surface being replicated; and means for releasing said device together with the first means from the surface.
Claim 6
Dependent Claim
39 words
A device as claimed in claim 1 which includes means within said housing to divide said housing into an upper and a lower chamber and further including means to selectively admit and remove air and water from said chambers.
Claim 7
Dependent Claim
17 words
A device as claimed in claim 4 in which said means to divide is a flexible diaphram.
Claim 8
Dependent Claim
64 words
A device as claimed in claim 5 in which said first means includes: a container mounted on one side of said diaphram; a removable and replaceable replicating material mounted within said container, said container being movable within said housing from a position in which said replicating material is withheld from the surface being replicated to a position in which said material contacts the surface.
Claim 9
Dependent Claim
23 words
A device as claimed in claim 6 in which said container is mounted within said lower chamber and is attached to said diaphram.
Claim 10
Dependent Claim
25 words
A device as claimed in claim 3 in which said second means comprises a deformable magnetic gasket attached to the bottom edge of said housing.
Claim 11
Dependent Claim
17 words
A device of claim 3 wherein said first means includes a wax composition as a replication material.
Claim 12
Dependent Claim
16 words
A device of claim 3 wherein said first means includes a thermo-plastic as a replicating material.
Claim 13
Dependent Claim
18 words
A device of claim 9 wherein said first means includes thermo plastic materials with additives for mold release.
Claim 14
Dependent Claim
17 words
A device of claim 3 wherein said first means includes a metallic colloid for improved heat transfer.
Claim 15
Dependent Claim
17 words
A device as claimed in claim 6 wherein a heating element is embedded in said replicating material.
