Abstract
Abstract A pair of wheels and shrouds are mounted behind the rear wheels of a load-hauling vehicle and are arranged with the wheels adapted to telescope one within each of the shrouds. The wheels and shrouds are pivotally mounted for movement about the same axis for either independent or joint movement toward and away from engagement with the ground. Wheel engagement with the ground cooperates in load distribution during transportation while shroud engagement enhances vehicle stability during loading and unloading.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
174 words
An auxiliary assembly for a vehicle comprising in combination: wheel means; means for pivotally mounting said wheel means on the rear portion of a vehicle frame behind the rear wheels of said vehicle for movement about an axis for raising and lowering said wheels into and out of engagement with the ground; jack means including a first shroud mounted to fit over said wheel means; means for pivotally mounting said jack means on the rear portion of said frame behind the rear wheels of said vehicle for movement about an axis for raising and lowering said jack means into and out of engagement with the ground; and means connected to said wheel means and jack means and operable to raise and lower said wheel means and said jack means jointly or independently so that, when said vehicle is in motion, said wheel means may be lowered to cooperate with the remaining vehicle wheels in load carrying and, when said vehicle is standing, said jack means may be lowered to provide stability for said vehicle.
Claim 2
Dependent Claim
174 words
An auxiliary assembly for a vehicle comprising in combination: wheel means; means for pivotally mounting said wheel means on the rear portion of a vehicle frame behind the rear wheels of said vehicle for movement about an axis for raising and lowering said wheels into and out of engagement with the ground; jack means including a first shroud mounted to fit over said wheel means; means for pivotally mounting said jack means on the rear portion of said frame behind the rear wheels of said vehicle for movement about an axis for raising and lowering said jack means into and out of engagement with the ground; and means connected to said wheel means and jack means and operable to raise and lower said wheel means and said jack means jointly or independently so that, when said vehicle is in motion, said wheel means may be lowered to cooperate with the remaining vehicle wheels in load carrying and, when said vehicle is standing, said jack means may be lowered to provide stability for said vehicle.
Claim 3
Dependent Claim
22 words
The assembly according to claim 1 wherein said first shroud and wheel means are mounted for pivotable movement about generally coincident axes.
Claim 4
Dependent Claim
103 words
The assembly according to claim 2 wherein said wheel means comprise a pair of wheels mounted separately, one on each side of said ( vehicle frame, and said jack means includes a pair of said first shrouds each mounted to fit over each of said wheels, said wheel means and jack means at each side of said vehicle mounted on axle means providing said coincident axes with the axle means mounting the wheel means and jack means on one side of said vehicle being separate from the axle means mounting the wheel means and jack means on the other side of said vehicle.
Claim 5
Dependent Claim
44 words
The assembly according to claim 3 wherein said means for raising and lowering said wheel and jack means comprise hydraulic ram cylinder means connected to each of said wheel means and jack means for moving said wheel means and jack means jointly and independently.
Claim 6
Dependent Claim
42 words
The assembly according to claim 3 including a pair of second shrouds, one in telescoping relation with each of said first shrouds, and wherein each of said wheel means is rotatably mounted within one of said second shrouds for pivotal movement therewith.
Claim 7
Dependent Claim
134 words
An auxiliary assembly for a vehicle comprising, in combination: a wheel; means mounting said wheel for rotation about its own axis and for Pivotal movement about a second axis to permit raising and lowering said wheel into and out of engagement with the ground; jack means including a first shroud adapted to fit over and enclose said wheel, means mounting said shroud for movement on said second axis for pivotal movement jointly with and independently of said wheel into and out of engagement with the ground; and means for raising and lowering said wheel and said jack means jointly and independently so that when said vehicle is in motion, said wheel may be lowered to provide load equalization and, when said vehicle is standing, said jack means may be lowered to provide static stability.
Claim 8
Dependent Claim
134 words
An auxiliary assembly for a vehicle comprising, in combination: a wheel; means mounting said wheel for rotation about its own axis and for Pivotal movement about a second axis to permit raising and lowering said wheel into and out of engagement with the ground; jack means including a first shroud adapted to fit over and enclose said wheel, means mounting said shroud for movement on said second axis for pivotal movement jointly with and independently of said wheel into and out of engagement with the ground; and means for raising and lowering said wheel and said jack means jointly and independently so that when said vehicle is in motion, said wheel may be lowered to provide load equalization and, when said vehicle is standing, said jack means may be lowered to provide static stability.
Claim 9
Dependent Claim
32 words
The assembly according to claim 6 including a second shroud in telescoping relation within said first shroud, and wherein said wheel is rotatably mounted within said second shroud for pivotal movement therewith.
