Abstract
Abstract A carrier for transporting mobile and modular homes which are constructed without wheels and steel underframe, which carrier has a stationary frame with two parallel longitudinally extending hollow box beams connected together by fixed cross braces, and is mounted on a plurality of wheel axles for both lateral movement in the direction of the length of the axles and for vertical movement relative to the axles. An adjustable frame having two parallel longitudinally extending beams slightly smaller in cross-section than the box beams of the stationary frame is mounted on the stationary frame with the box beams of the adjustable frame slidable into the box beams of the stationary frame. The beams of the adjustable frame are connected by removable cross braces, which are removed as the adjustable frame is telescoped into the stationary frame. Outriggers are provided on the forward end of the adjustable frame, and the adjustable frame is slidable laterally on the outriggers when the outriggers are in the extended position and support the adjustable frame on the ground, and is movable vertically relative to the outriggers when the outriggers are in the extended position.

Claim 1
Independent Claim
355 words
A carriEr for transporting a single-wide or half of a doublewide mobile home or modular home constructed without wheels and steel underframe, comprising a stationary frame having a pair of parallel hollow box beams and fixed cross braces between them securing them to each other, an adjustable frame comprising a pair of parallel beams slidable telescopically in the stationary box beams of the stationary frame and having removable cross brace between them securing them to each other, lock means locking the frames to each other in any of a plurality of positions, a plurality of pairs of wheels and an axle extending between each pair of wheels, a wheel chassis slidably mounted on said axles for movement in the direction of the length of said axles, said stationary frame being mounted on said wheel chassis for vertical movement relative to said wheel chassis and extending transversely to the direction of length of said axles, an outrigger housing adjacent the end of the adjustable frame remote from the stationary frame extending substantially parallel with said axles and having outrigger support means depending therefrom for contact with the ground beneath the carrier, outrigger slide means slidably mounted on said outrigger housing, the adjustable frame being mounted on said outrigger slide means for vertical movement relative to said outrigger slide means and extending transversely to the direction of length of said outrigger housing, raising and lowering means between the wheel chassis and the stationary frame and between the outrigger housing and the adjustable frame for raising and lowering the frames together, and lateral shifting means between said axles and said wheel chassis and between said outrigger housing and said outrigger slide means for shifting the wheel chassis and the outrigger slide means together in one or the other direction transversely of the length of the frames, whereby the frames can be shifted up and down relative to the wheels and the outrigger housing and can be shifted laterally back and forth relative to the wheels and the outrigger housing for adjusting the position of the mobile or modular home or a part of it at the installation site.

A carriEr for transporting a single-wide or half of a doublewide mobile home or modular home constructed without wheels and steel underframe, comprising a stationary frame having a pair of parallel hollow box beams and fixed cross braces between them securing them to each other, an adjustable frame comprising a pair of parallel beams slidable telescopically in the stationary box beams of the stationary frame and having removable cross brace between them securing them to each other, lock means locking the frames to each other in any of a plurality of positions, a plurality of pairs of wheels and an axle extending between each pair of wheels, a wheel chassis slidably mounted on said axles for movement in the direction of the length of said axles, said stationary frame being mounted on said wheel chassis for vertical movement relative to said wheel chassis and extending transversely to the direction of length of said axles, an outrigger housing adjacent the end of the adjustable frame remote from the stationary frame extending substantially parallel with said axles and having outrigger support means depending therefrom for contact with the ground beneath the carrier, outrigger slide means slidably mounted on said outrigger housing, the adjustable frame being mounted on said outrigger slide means for vertical movement relative to said outrigger slide means and extending transversely to the direction of length of said outrigger housing, raising and lowering means between the wheel chassis and the stationary frame and between the outrigger housing and the adjustable frame for raising and lowering the frames together, and lateral shifting means between said axles and said wheel chassis and between said outrigger housing and said outrigger slide means for shifting the wheel chassis and the outrigger slide means together in one or the other direction transversely of the length of the frames, whereby the frames can be shifted up and down relative to the wheels and the outrigger housing and can be shifted laterally back and forth relative to the wheels and the outrigger housing for adjusting the position of the mobile or modular home or a part of it at the installation site.
Claim 3
Dependent Claim
24 words
A carrier as claimed in claim 1 in which said raising and lowering means and said lateral shifting means are both hydraulic piston-cylinder means.
Claim 4
Dependent Claim
81 words
A carrier as claimed in claim 1 in which said wheel chassis comprises a plurality of lateral sleeves beneath the box beams on each side of the stationary frame, and frame members connecting the lateral sleeves on one side of the stationary frame to each other, and said lateral shifting means comprises a lateral shift cylinder mounting frame secured to said axles and hydraulic piston-cylinder mechanisms mounted on said mounting frame and having piston rods extending therefrom to said frame members.
Claim 5
Dependent Claim
51 words
A carrier as claimed in claim 1 in which said outrigger housing has a mounting frame thereon, said outrigger slide means comprise a pair of outrigger slides one beneath each side frame, and said lateral shifting means comprises hydraulic piston-cylinder mechanisms mounted between said mounting frame and the respective outrigger slides.
Claim 6
Dependent Claim
113 words
A carrier as claimed in claim 1 in which said wheel chassis comprises a plurality of lateral sleeves beneath the box beams on each side of the stationary frame, and frame members connecting the lateral sleeves on one side of the stationary frame, a vertical guide plate extending upwardly from each sleeve and engaging the outside surface of the box beam thereabove, and pairs of vertical telescoping sleeves, one vertical sleeve of a pair on each lateral sleeve and the other of the pair on the box beam of the stationary frame thereabove, said guide plates and pairs of vertical sleeves guiding said stationary frame in its vertical movement on said wheel chassis.
Claim 7
Dependent Claim
96 words
A carrier as claimed in claim 1 in which said outrigger slide comprises two slide elements, one beneath each parallel beam of said adjustable frame, and a vertical guide platE extending upwardly from each slide element and engaging the outside surface of the beam thereabove, and a pair of vertical telescoping sleeves, one vertical sleeve of a pair on each slide element and the other of the pair on the beam of the adjustable sleeve thereabove, said guide plates and pairs of vertical sleeves guiding said adjustable frame in its vertical movement on said outrigger housing.
