Boom support strand oscillation dampening mechanism

1. An apparatus including a main housing including a generally horizontal platform, a boom extending from the platform, a bucket suspended from the boom, a mast extending from the platform, a boom support strand extending between and attached to said mast and said boom, and

a boom support strand oscillation dampening mechanism comprising a brace,

a rope extending between and attached to said brace and said boom, and

a boom support strand clamp mechanism connected to said brace and including

a first clamp block,

a second clamp block,

a flexible enclosure placed between the first clamp block and the second clamp block, said boom support strand being within said flexible enclosure, said flexible enclosure having a length, as measured from its midsection to either end of the flexible enclosure, of more than 2 times longer than the inside diameter of the flexible enclosure, and

means for holding said first clamp block to said second clamp block so that said flexible enclosure is clamped between said first clamp block and said second clamp block.

2. An apparatus in accordance with claim 1 wherein said flexible enclosure has a midsection attached to its respective brace by the clamp mechanism.

3. An apparatus in accordance with claim 1 wherein the flexible enclosure has a midsection and wherein said flexible enclosure is tapered down towards its ends from near its midsection.

4. An apparatus in accordance with claim 3 wherein said flexible enclosure includes steps of decreasing diameter as the outer surface leaves the flexible enclosure's midsection and nears either end of the flexible enclosure.

5. An apparatus in accordance with claim 1 wherein said flexible enclosure is made of synthetic material.

6. An apparatus in accordance with claim 5 wherein said flexible enclosure is made of an elastomer toughened thermoplastic material, and the clamp mechanism is made of steel.

7. An apparatus in accordance with claim 6 wherein the flexible enclosure is made of two components mixed together and cured, the two components comprising one component made of caprolactam and a prepolymer in the form of a polyl based on polyether, and the other component made of a curing catalyst and caprolactam.

8. An apparatus in accordance with claim 1 wherein said flexible enclosure is split into two identical halves and is held together by the clamp mechanism.

9. An apparatus in accordance with claim 1 wherein said flexible enclosure length, as measured from its midsection to either end of the flexible enclosure, is more than 3 times longer than the inside diameter of the flexible enclosure.

10. An apparatus in accordance with claim 1 wherein said rope is made of polyester.

11. An apparatus including a main housing including a generally horizontal platform, a boom extending from the platform, a bucket suspended from the boom, a mast extending from the platform, a mast support strand extending between and attached to said platform and said mast, a boom support strand extending between and attached to said mast and said boom, and

a boom support strand oscillation dampening mechanism comprising

a left brace and a right brace spaced apart from said left brace,

a polyester rope extending between each of said braces and said boom, each of said ropes being attached to said boom,

a device for attaching said rope to said brace, and

a boom support strand clamp mechanism connected to said brace and including

a first clamp block,

a second clamp block,

a flexible enclosure placed between the first clamp block and the second clamp block, said boom support strand being within said flexible enclosure, and

wherein the flexible enclosure has a length, as measured from its midsection to either end of the flexible enclosure, of more than 2 times longer than the inside diameter of the flexible enclosure, and

means for holding said first clamp block to said second clamp block so that said flexible enclosure is clamped between said first clamp block and said second clamp block.

12. An apparatus in accordance with claim 1 wherein said apparatus further includes a device for attaching said rope to said brace, said rope attaching device comprising

two spaced-apart parallel pivot plates,

two spaced-apart pin connections, one pivotally attaching said pivot plates to said brace, the other having the end of the rope trained around said pin connection,

a rope stay for securing said trained portion of said rope around said pivot pin connection, and

a cover over said trained portion of said rope and between said stay and said pivot plate.

13. An oscillation dampening mechanism adapted to be used with an apparatus including a generally horizontal platform, a boom extending from the platform, a bucket suspended from the boom, a mast extending from the platform, and a boom support strand extending between and attached to the mast and the boom, said oscillation dampening mechanism comprising a brace, a rope extending between and attached to said brace and said boom, and

a boom support strand clamp mechanism connected to said brace and including

a first clamp block,

a second clamp block,

a flexible enclosure placed between the first clamp block and the second clamp block, said boom support strand being within said flexible enclosure, said flexible enclosure having a length, as measured from its midsection to either end of the flexible enclosure, of more than 2 times longer than the inside diameter of the flexible enclosure, and

means for holding said first clamp block to said second clamp block so that said flexible enclosure is clamped between said first clamp block and said second clamp block.

14. An oscillation dampening mechanism in accordance with claim 13 wherein said rope is made of polyester.
