Railcar airbrake system for attachment to machinery

Abstract

A railcar airbrake system for attachment to or integration into machinery, such as a wheel loader preferably includes a rail car coupler, a glad hand air hose, a compressor, an air storage tank and a sliding base frame. The sliding base frame preferably includes a plurality of top and bottom supports, a base support plate, top and bottom cross members, a coupler slide device and two vertical support posts. The railcar coupler and the glad hand air hose are retained in the coupler slide device. The plurality of supports, the cross members, plate and posts are used to create a structure, which incorporates the slide base frame. The air storage tank and the compressor are secured to the base support plate. The compressor supplies compressed air to the air storage tank. The air storage tank supplies compressed air to the glad hand air hose.

That's rather bizarre to me. We had trainline air on machines years ago. Very similar to this machine I am linking. I'm not sure how you patent something that's already in existence and in use. I know the knew Swingmaster units were available with a knuckle and air hookup for car moving as well because we had one probably 15 years ago. We also had a Cat 966 loader with a compressor setup and knuckle on it that was used for car moving. Here is a link to an older Swingmaster 360 with the knuckle and air tank for train air.
