Abstract
A hitch (10) for releasably connecting a double stack trailer to a road railer car having a tongue (14) having an opening (15) includes a top wall (16), bottom wall (24) and first and second walls (28) and (30) cooperatively connected to form a housing (12) for receiving the tongue (14) of the road railer car. The housing (12) has an upper pin receiving opening (18) in the top wall (16), and a lower pin receiving opening (26) in the bottom wall (24). The upper and lower pin receiving openings (18) and (26) are in alignment. A shaft (42) is positioned below the bottom wall (24) and cooperatively connected between the first side wall (28) and the second side wall (30). A lever (22) has an upper arm (44) cooperatively connected to a lower arm (46) with a pivot point (48) positioned between the arms (44) and (46 ). The lever (22) has a portion of the upper arm (44) extending above the top wall (16), and the lower arm (46) is positioned below the bottom wall (24). A pin (50) is cooperatively connected to the lower arm (46). When in a disengaged position the pin (50) is in the lower pin receiving opening (26). When the upper arm (44) is depressed the pin (50) moves upward through the upper pin receiving opening (18) thereby securing the tongue (14) through its opening (15) which has been positioned in the housing (12).

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
