Abstract
A retro-fittable mobility kit enables one person alone to conveniently move a heavy machine such as wood or metal-working machine of the type that is originally designed to remain in a fixed location, and that normally would require special handling equipment and/or several persons available, should it become necessary to move the machine. The mobility kit includes (a) a pair of fixed wheel assemblies to be mounted on each side toward a first end of the machine, each having a wheel partially enclosed in a metal bracket, and (b) one front swivel caster wheel assembly that mounts onto a central location at the second end of the machine. A preferred embodiment provides an adjustable clamping system on each of the three assemblies for attachment onto a structural member such as bottom framework of the machine, a fixed wheel assembly on each the side toward the first end, and a swivel caster in a central location at the second end. The preferred embodiment also provides a foot-pedal-activated caster height selection mechanism that retracts and extends the swivel caster, and provides two strong rubber feet attached under the second end bracket ledge on which the second end portion of the machine rests when the swivel caster has been retracted. To make the machine mobile and maneuverable, the operator actuates the pedal by foot so as to extend the caster downwardly to an extended position, lifting the second end of the host machine off the rubber feet. To render the host machine stationary so it can be operated, the operator actuates the pedal in an opposite manner so as to retract the swivel caster and place the weight of the second end of the machine on the floor via the feet; the fixed side wheels remain on the floor at all times.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
