Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
140 words
Apparatus comprising, a - a core member secured to a base, b - a cylindrical barrel, c - means mounting the barrel for rotation about the axis of the core member, d - elastically-deformable means opposing rotation of the barrel relative to the core member, e - a multi-turn winding disposed within said barrel, f - movable contact means establishing electrical contact with turns of said winding, g - drive means imparting movement to the said movable contact means in correspondence with rotation of the said barrel, h - an electrical instrument having a movable coil, i - a source of d.c. voltage connected across the center turn of said winding and both ends of the winding, and j - circuit elements connecting the said movable coil across the center turn of the winding and the said movable contact means.
Claim 2
Dependent Claim
140 words
Apparatus comprising, a - a core member secured to a base, b - a cylindrical barrel, c - means mounting the barrel for rotation about the axis of the core member, d - elastically-deformable means opposing rotation of the barrel relative to the core member, e - a multi-turn winding disposed within said barrel, f - movable contact means establishing electrical contact with turns of said winding, g - drive means imparting movement to the said movable contact means in correspondence with rotation of the said barrel, h - an electrical instrument having a movable coil, i - a source of d.c. voltage connected across the center turn of said winding and both ends of the winding, and j - circuit elements connecting the said movable coil across the center turn of the winding and the said movable contact means.
Claim 3
Dependent Claim
58 words
The invention as recited in claim 1, wherein the said barrel has inwardly-directed, spaced radial webs, wherein the said core member has outwardly-directed, spaced webs positioned between the webs of the barrel, and wherein the said elastically-deformable means is in the form of rods, each rod being positioned between adjacently-disposed webs of the barrel and the core member.
Claim 4
Dependent Claim
98 words
The invention as recited in claim 2, wherein the turns of said winding have portions substantially equally spaced from a contact bar, wherein the said movable contact means is a metal ball rotatable about and slidable along a slide rod, said ball being in electrical contact with the said contact bar and the turns of said winding, wherein an end of said slide rod is secured to a disc mounted for rotation about its axis, and wherein the said disc is mechanically-coupled to said barrel; the said slide rod and the said disc constituting the said drive means.
Claim 5
Dependent Claim
49 words
The invention as recited in claim 3, wherein the said disc is mechanically-coupled to the barrel by a link rod having one end portion slidably recEived in a hole formed in said disc and the other end portion inserted into a hole formed in the rim of said barrel.
Claim 6
Dependent Claim
57 words
The invention as recited in claim 4, including a cap secured to an end of said barrel and having diametrically-opposed arms extending therefrom, wherein the said cap, barrel and base form a bitt, and wherein the said instrument has a scale calibrated in factors indicative of the pounds pull of an anchor line secured to the bitt.
