DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The preferred method will now be described with reference to FIGURES 1 through 3.
:~tructure and Relationship of Part~~:
Referring to FIGURE 1. a method of securing auxiliary ~~rheels to a motorcycle, has a first step of extending an axle 12 in a position underlying a frame 14 of a motorcycle ~~6. Referring to FIGURE 3. axle 12 has opposed ends 18.
Referring to FIGURE 1, Each of opposed ends 18 has an li; upstanding attachment member 20 positioned adjacent each of opposed ends 18 and a wheel 22 mounted to each of opposed ends 18 of axle 12. In the il_Lustrated embodiment, attachment members 20 have an angular brace 24.
Referring to FIGURE 2, a second ~~tep involves securing a mounting bracket 26 to each of opposed sides 28 of frame 14 which is spaced forward of axle 12. Referring to FIGURE
1, in the illustrated embodiment, mount-ing bracket 26 is ~~U"
shaped. Each of mounting brackets 26 supports a bearing 30 ,.which defines a substantially horizontal pivot axis 32. In ~~he illustrated embodiment, horizontal pivot axis 32 is at approximately wheel height.
A third step involves securing each of attachment members 20 on axle 12 to bearings 30 of mounting brackets 26, such that attachment members 20 ~~ivot about horizontal pivot axis 32 in response to upward and downward movement of axle 12.
A fourth step involves proVic~ing and positioning between axle 12 and motorcycle ==came 14 means for maintaining wheels 12 in contact with the ground. In the illustrated embodiment, a compression spring coil-over a fluid shock 36 dampens movement of axle 12. In addition, a pressure block 38 is positioned on axle 12. A portion of the weight of motorcycle 16 rests upon pressure block 38.
This helps maintain wheels 22 in contact with the around.
Pressure block 38 is positioned at a central position on axle 12. Two five inch pieces of square tubing are welded onto axle 12. A steel plate is then welded to the square tubing to make a platform for positioning pressure block 38.
Pressure block 38 is a round rubber block about the diameter of a hockey puck, only twice as thick. Pressure block 38 is bonded to the platform. The amount of weight exerted upon pressure block 38 by the motorcycle frame is approximately twenty pounds. The thickness of pressure block 38 is selected and, if necessary, adjusted, so that only the approximately twenty pounds of the weight of the ~notercycle is pushing down on pressure block 38. It would be undesirable to use pressure block 38 to take weight off the back tire of motorcycle 16, as this could have adverse effects upon traction of the back tire. The weight on axle 12 need only be sufficient to ensure that wheels 22 have enough grip to avoid sideways slip;sage or skidding on corners or slippery road conditions.
Advantages:
A first benefit of the above described method of securing auxiliary wheels to a motorcycle that there is more clearance than the prior art. This al-_ows the motorcycle to climb or descend steep inclines. It allows the motorcycle to step over obstacles. A second benefit is that the i working components are all exposed, and, consequently, the apparatus is easier to inspect and service. A third benefit is that the configuration places the wheels in a wider apart stance, thereby enhancing the stability of a motorcycle for safer cornering. A fourth benefit is that the entire configuration is stronger resulting in less wear on the ~J
original components of a motorcycle. A fifth benefit is that the apparatus may be added onto tr.e motorcycle without sacrificing the other components of a motorcycle, especially the kickstand which can now double as a servicing position.
In this patent document, the word "comprising" is used vn its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are ~ not excluded. A reference to an element by the indefinite article "a" does not exclude the possibility that more than cne of the element is present, unles:~ the context clearly requires that there be one and only one of the elements.
It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Maims.

A portion of the weight of motorcycle 16 rests upon pressure block 38.
This helps maintain wheels 22 in contact with the around.
Pressure block 38 is positioned at a central position on axle 12. Two five inch pieces of square tubing are welded onto axle 12. A steel plate is then welded to the square tubing to make a platform for positioning pressure block 38.
Pressure block 38 is a round rubber block about the diameter of a hockey puck, only twice as thick. Pressure block 38 is bonded to the platform. The amount of weight exerted upon pressure block 38 by the motorcycle frame is approximately twenty pounds. The thickness of pressure block 38 is selected and, if necessary, adjusted, so that only the approximately twenty pounds of the weight of the ~notercycle is pushing down on pressure block 38. It would be undesirable to use pressure block 38 to take weight off the back tire of motorcycle 16, as this could have adverse effects upon traction of the back tire. The weight on axle 12 need only be sufficient to ensure that wheels 22 have enough grip to avoid sideways slip;sage or skidding on corners or slippery road conditions.
