Abstract

A gas powered internal combustion engine in which the gas is provided from pressurized liquid gas in an LPG container and in which the LPG container is rigidly mounted adjacent to the internal combustion engine at a preselected angle to be in conductive heat transfer relationship to the internal combustion engine and in vibration receiving relationship to the internal combustion engine whereby the liquified gas in the LPG container is heated and the effective surface area thereof is increased.

Claims (43)

1. A gas powered internal combustion engine drive arrangement comprising, in combination:

an internal combustion engine for rotating an output shaft for said internal combustion engine in an operating condition thereof;

a mounting bracket rigidly connected to said internal combustion engine for receiving heat and vibration from said internal combustion engine;

a liquified gas storage bottle arrangement having liquified gas therein and gas phase of said liquified gas therein rigidly and removably mounted on said mounting bracket for receiving said heat and vibration therefrom for agitating and heating said liquified gas stored in said liquified gas storage bottle to increase the generation of gas phase therefrom;

a strap connected to said mounting bracket for engaging said liquified gas storage bottle arrangement to secure said mounting of said liquified gas storage bottle arrangement on said mounting plate.

2. The arrangement defined in claim 1 and further comprising:

said strap further comprises an over center fastener.

3. The arrangement defined in claim 2 and further comprising:

said liquified gas storage bottle arrangement comprises a generally cylindrical gas storage bottle having a predetermined outer circumference having a predetermined curvature;

an outlet conduit having a first end connected to said liquified gas storage bottle and a second end connected to said internal combustion engine for providing said gas phase of said liquified gas thereto, whereby said internal combustion engine receives said gas phase for operation thereof and said internal combustion engine generates said heat and said vibration for the condition of said internal combustion engine operating.

4. The arrangement defined in claim 3 wherein:

said mounting plate has arcuate wall portions having a curvature to substantially match said predetermined curvature of said predetermined outer circumference of said generally cylindrical gas storage bottle;

said liquified gas storage bottle is mounted on said mounting plate at a preselected angle to the horizontal sufficient to increase the surface area of said liquified gas therein.

5. The arrangement defined in claim 4 wherein:

said preselected angle is in the range of 14° and 16°.

6. The arrangement defined in claim 5 wherein:

said preselected angle is approximately 15°.

7. The arrangement defined in claim 1 and further comprising:

said output shaft of said internal combustion engine is connected to a powered tool selected from the class consisting of a leaf blower, an edge trimmer, a weed cutter, a hedge trimmer, a small reciprocating saw, a small chain saw and a lawn mower, whereby said powered tool is powered by the rotation of said output shaft.

8. The arrangement defined in claim 7 and further comprising

said strap further comprises an over center fastener.

9. The arrangement defined in claim 8 and further comprising:

said liquified gas storage bottle comprises a generally cylindrical gas storage bottle having a predetermined outer circumference having a predetermined curvature;

an outlet conduit having a first end connected to said liquified gas storage bottle and a second end connected to said internal combustion engine for providing said gas phase of said liquified gas thereto, whereby said internal combustion engine receives said gas phase for operation thereof and said internal combustion engine generates said heat and said vibration for the condition of said internal combustion engine operating.

10. The arrangement defined in claim 9 wherein:

said mounting plate has arcuate wall portions having a curvature to substantially match said predetermined curvature of said predetermined outer circumference of said generally cylindrical gas storage bottle; and,

said liquified gas storage bottle is mounted on said mounting plate at a preselected angle to the horizontal sufficient to increase the surface area of said liquified gas therein.

11. The arrangement defined in claim 10 wherein:

said preselected angle is in the range of 14° and 16°.

12. The arrangement defined in claim 11 wherein:

said preselected angle is approximately 15°.

13. The arrangement defined in claim 7 wherein:

said powered tool is a leaf blower.

14. The arrangement defined in claim 7 wherein:

said powered tool is a string trimmer.

15. The arrangement defined in claim 7 wherein:

said powered tool is a lawn mower.

16. The arrangement defined in claim 7 wherein:

said powered tool is a one of a reciprocating saw and a rotating saw.

17. The arrangement defined in claim 16 wherein:

said powered tool is a small chain driven reciprocating saw.

18. The arrangement defined in claim 16 wherein:

said powered tool is a small chain driven rotating saw.
