  • Patent number: 6238009
    Abstract: A wheel adapter that adapts a conventional vehicle hub to a wheel having a large inward offset, thereby permitting the original wheel track of the vehicle to be changed to match the width of a railroad track so the tires of the vehicle will sit on the railroad track. The adapter locates the wheel to avoid contact with a brake caliper on the vehicle.

  • Patent number: 5119723
    Abstract: The subject invention is an improved apparatus adapted to facilitate the installation of railroad ties, either by automatic or semi-automatic members. The apparatus incorporating the features of the subject invention comprises, in general, a pair of laterally disposed stabilizing and leveling arms flexibly mounted to each side of a vehicle that is capable of riding on railroad tracks, and wherein each said stabilizing and leveling arm is in turn comprised of two flexible subarms flexibly mounted together in the manner of a parallelogram structure. Mounted at the end of the parallelgram-like subarms are flat brace members. Integrally affixed to the end of such flat brace members are self-levelling jacks. A flexible movable boom member is integrally mounted to a portion of such vehicle, with such boom member having a rotatable holding device rotatably and integrally affixed to the end of the boom arm, such holding device adapted to hold a portion of a tie member.

  • Patent number: 4960359
    Abstract: The subject device is an operational apparatus for front end loaders. The apparatus can be adapted directly onto the front end loader linkage arms at the attaching points that normally a bucket is attached to or can adapted by the means of a quick coupling attachment. The subject device should be used with a quick coupling device but is not limited to this device for its operation. The subject device herein is specifically adapted to a front end loader as an operational apparatus to perform various work functions such as a mobile crane, a front end loader, a fork lift or similar work functions in construction or railroad use but with an added dimension, that being the ability to swing 90.degree.. Such a unit comprises an auxiliary operational mechanism having dimensional power motions when attached to a front end loader and is basically a swinging, lifting and tilting member for three dimensional movement actuated by hydraulic cylinders.

  • Patent number: 4941408
    Abstract: The subject invention is an improved frame mechanism adapted to be deployed and otherwise integrally affixed on a land based motor vehicle that is adapted to retrofitted with rail wheels in addition to conventional land based wheels, in order to enable the motor vehicle to ride on railroad tracks, in addition to being capable of being driven on non-rail surfaces. The apparatus incorporating the features of the subject invention comprises, in general, a longitudinally extending support system adapted to hold the rail wheels therein, which support system is connected to the motor vehicle base frame in a transverse manner, said support system being constructed to be laterally shortened or elongated to move the wheel members inwardly or outwardly to correspondingly adjust the distance between the rail wheels.
