Abstract
Abstract Tool-carrying track-confined and guided vehicles have running gear including roller assemblies of which those on one side may be so moved relative to those on other side as to effect release for removal of the vehicle from the track. The moveable roller assemblies are journalled for swivelling in opposite ends of a horizontal beam connected to the vehicle underside for limited rotation about a central vertical post and for transverse spatial adjustment. Gear transversely shiftable provides optimum loading on all roller assemblies.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
158 words
A clamping assembly for use with the combination embodying (i) a vehicle, (ii) track means, (iii) restricting means for confining said vehicle to vehicle contacting portions of said track means, and (iv) transversely variable spacable wheel or roller means, said clamping assembly being characterized by comprising a two-point load-balancing roller-to-track locking and releasing means movable bodily toward or away from said contacting portions, a mounting assembly, manually operable means for moving said locking and releasing means twoard or away from said vehicle contacting portions while in said mounting assembly, said clamping assembly being attached to said vehicle, said wheel or roller means being swivellably connected to said locking and releasing means in substantially spaced relationship, and a pair of substantially spaced wheel or roller assemblies, each pair having two angularly related wheels or rollers, said locking and releasing means including a horizontally disposed beam, said wheel or roller assemblies being attached to the opposite ends of said beam.
Claim 2
Dependent Claim
158 words
A clamping assembly for use with the combination embodying (i) a vehicle, (ii) track means, (iii) restricting means for confining said vehicle to vehicle contacting portions of said track means, and (iv) transversely variable spacable wheel or roller means, said clamping assembly being characterized by comprising a two-point load-balancing roller-to-track locking and releasing means movable bodily toward or away from said contacting portions, a mounting assembly, manually operable means for moving said locking and releasing means twoard or away from said vehicle contacting portions while in said mounting assembly, said clamping assembly being attached to said vehicle, said wheel or roller means being swivellably connected to said locking and releasing means in substantially spaced relationship, and a pair of substantially spaced wheel or roller assemblies, each pair having two angularly related wheels or rollers, said locking and releasing means including a horizontally disposed beam, said wheel or roller assemblies being attached to the opposite ends of said beam.
Claim 3
Dependent Claim
28 words
The clamping assembly according to claim 1 in which said beam is pivotally connected substantially centrally thereof to said mounting assembly for limited rotation in a horizontal plane.
Claim 4
Dependent Claim
72 words
The wheel or roller assemblies according to claim 1 in which each assembly is characterized by being in the form of a pair of swivelling generally flat-tired rollers arranged in axially co-planar axially angular relationship so as to present a recess on the common axial plane of said pair, which recess is essentially of V-conformation so as to engage an elongated complementary conformation of the vehicle contacting portions of said track means.
Claim 5
Dependent Claim
28 words
The clamping assembly according to claim 3 in which said beam is pivotally connected substantially centrally thereof to said mounting assembly for limiting rotation in a horizontal plane.
Claim 6
Dependent Claim
30 words
The clamping assembly according to claim 3 in which said beam is wholly moveable sideways toward to away from said track means through the agency of said manually operable means.
Claim 7
Dependent Claim
23 words
The clamping assembly according to claim 3 in which said beam is also rotatable through a limited horizontal arc about its center point.
Claim 8
Dependent Claim
101 words
The invention according to claim 3 in which said manually operable means are in the form of screw means secured for rotation without thrust in at least one of a pair of rocker flanges on said vehicle, said screw means projecting inwardly from said rocker flanges, said locking and releasing means being threadably connected to said screw means for inward and outward movement upon manual operation of said screw means to lock said wheel or roller assemblies to said track means and release the same therefrom respectively, said beam lying essentially parallel to said rocker flanges upon the inner sides thereof.
Claim 9
Dependent Claim
100 words
The clamping assembly according to claim 1 in which said wheel or roller means are in the form of a pair of substantially spaced wheel or roller assemblies, said locking and releasing means including a horizontally disposed beam, said wheel or roller assemblies being attached to the opposite ends of said bEam, said beam being moveable horizontally sideways toward or away from said track means vehicle contacting portions on actuation of said manually operable means, said beam being pivotally connected to said mounting means for limited rotation in a horizontal plane, said beam being so rotatable about substantially its center.
Claim 10
Dependent Claim
148 words
The locking and releasing means according to claim 8 in which said manually operable means are in the form of screw means secured for rotation without thrust in at least one of the rocker flanges of said vehicle and projecting inwardly therefrom, said locking and releasing means including a vertical post, said bean being rotatably mounted upon said post, said post being provided with a screw-threaded aperture at right angles to its vertical axis, said screw means extending through said screw-threaded aperture for causing inward and outward movement of said post and beam upon manual operation of said screw means and thereby rollably lock said wheel or roller assemblies to said track means or release the same therefrom respectively, said mounting assembly including guide means for controlling the inward and outward movement of said beam and post at right angles to the direction of travel of said carriage.
Claim 11
Dependent Claim
100 words
The clamping assembly according to claim 1 in which said wheel or roller means are in the form of a pair of substantially spaced wheel or roller assemblies, said locking and releasing means including a horizontally disposed beam, said wheel or roller assemblies being attached to the opposite ends of said beam, said beam being moveable horizontally sideways toward or away from said track means vehicle contacting portions on actuation of said manually operable means, said beam being pivotally connected to said mounting means for limited rotation in a horizontal plane, said beam being so rotatable about substantially its center.
Claim 12
Dependent Claim
148 words
The locking and releasing means according to claim 10 in which said manually operable means are in the form of screw means secured for rotation without thrust in at least one of the rocker flanges of said vehicle and projecting inwardly therefrom, said locking and releasing means including a vertical post, said beam being rotatably mounted upon said post, said post being provided with a screw-threaded aperture at right angles to its vertical axis, said screw means extending through said screw-threaded aperture for causing inward and outward movement of said post and beam upon manual operation of said screw means and thereby rollably lock said wheel or roller assemblies to said track means or release the same therefrom respectively, said mounting assembly including guide means for controlling the inward and outward movement of said beam and post at right angles to the direction of travel of said carriage.
Claim 13
Dependent Claim
30 words
The clamping assembly according to claim 1 in which said beam is wholly moveable sideways toward or away from said track means through the agency of said manually operable means.
Claim 14
Dependent Claim
23 words
The clamping assembly according to claim 12 in which said beam is also rotatable through a limited horizontal arc about its center point.
Claim 15
Dependent Claim
