Abstract
Abstract A motorized snow vehicle stand, for supporting the rear of the vehicle in a raised parking position so that the endless drive track is elevated above the ground, including a bail carried on a transverse horizontal pivot bar extended across the rear of the vehicle and rotatable through an arc of more than 180° from a raised or upright inoperate position where it is normally held against the rear of the vehicle by a manually releasable hook to a fully operative vehicle supporting position in engagement with the ground under the raised rear end of the vehicle where it is disposed in inclined position forward of dead center. The pivot bar is mounted on the vehicle in releasable nonrotatable relation and a spring is biased between the pivot bar and the bail, with provision for releasing and turning the bar to vary the spring tension. On release of the holding hook, the bail swings in two stages under action of the spring, namely through a first arc of less than 180° to engage the ground behind the vehicle and subsequently through a further arc when the vehicle is lifted allowing the bail to swing under the vehicle into an inclined position beyond or forward of dead center.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
205 words
For a motorized snow vehicle, a stand comprising a pivot bar attachable in transverse horizontal position across the rear of a motorized snow vehicle; means securing said bar in nonrotatable relation; a U-shaped bail having a spaced pair of parallel arms with a sleeve on the free end of each arm of said bail rotatably mounted on said bar; means normally holding said bail in raised inoperative position against the rear of the vehicle; and a spring biased between said nonrotatable bar and said bail acting to swing said bail downwardly into operative ground-engaging position beneath the vehicle, said bar having a threaded bore in each end, a bolt threaded in each said bore with a vehicle mounting bracket secured on the outer end of each said bolt, whereby the spread of the brackets is adjustable to the width of the vehicle frame and wherein each said bolt loosely carries a washer engageable with the near end of said bar and a jamb nut threaded on said bolt between said washer and said mounting bracket for tightening said washer against the end of the bar thereby capturing the bail arm sleeves on the bar and securing the bar against turning relative to said mounting brackets.

For a motorized snow vehicle, a stand comprising a pivot bar attachable in transverse horizontal position across the rear of a motorized snow vehicle; means securing said bar in nonrotatable relation; a U-shaped bail having a spaced pair of parallel arms with a sleeve on the free end of each arm of said bail rotatably mounted on said bar; means normally holding said bail in raised inoperative position against the rear of the vehicle; and a spring biased between said nonrotatable bar and said bail acting to swing said bail downwardly into operative ground-engaging position beneath the vehicle, said bar having a threaded bore in each end, a bolt threaded in each said bore with a vehicle mounting bracket secured on the outer end of each said bolt, whereby the spread of the brackets is adjustable to the width of the vehicle frame and wherein each said bolt loosely carries a washer engageable with the near end of said bar and a jamb nut threaded on said bolt between said washer and said mounting bracket for tightening said washer against the end of the bar thereby capturing the bail arm sleeves on the bar and securing the bar against turning relative to said mounting brackets.
Claim 3
Dependent Claim
101 words
The vehicle stand according to claim 1, wherein said bar has a radially extending cap screw threaded therein and said U-shaped bail has a radially extending cap screw threaded into the inside of one arm thereof near its sleeved free end, each of said cap screws having a transverse aperture through its outer end, the opposite ends of said spring being captured in the apertures of said respective screws, and said bar having a transverse bore for the reception of a removable pin for turning said bar to vary the tension of said spring on release of said bar securing means.
Claim 4
Dependent Claim
168 words
The vehicle stand according to claim 1, wherein said bail is rotatable on said bar through an arc of more than 180° from raised inoperative position against the rear of the vehicle to fully operative vehicle supporting position in engagement with the ground under the raised rear end of a vehicle where the said stand is disposed at an inclined position beyond dead center, such rotation of the bail occurring on the manual release of said bail holding means, under the action of said spring in two movements namely, a first rotation of less than 180° to initial ground contacting position where it declines at an angle to the vertical and a subsequent rotative movement through a further arc for a total rotation of more than 180° when the rear end of the vehicle is lifted allowing the bail to swing under the vehicle into an inclined position beyond dead center, and means for arresting the bail in such fully operative position against further rotation by said spring.
