Abstract
Abstract A ONE-WHEELED TRAILER FOR A CYCLE HAS A SINGLE TONGUE WHICH EXTENDS FORWARDLY ALONG ONE SIDE OF THE REAR WHEEL OF THE CYCLE AND IS CONNECTED TO THE CYCLE AT A POINT LATERALLY OFFSET FROM SUCH REAR WHEEL AND NEAR ITS CENTRAL AXIS. A HITCH FOR CONNECTING THE TONGUE TO THE CYCLE PERMITS THE TONGUE TO PIVOT RELATIVE TO THE CYCLE ABOUT TURNING AND PITCHING AXES, BUT PREVENTS RELATIVE MOVEMENT ABOUT A ROLL AXIS. THE HITCH INCLUDES A QUICK DISCONNECTING MEANS.
