  • Patent number: 6027134
    Abstract: A removable trailer tongue for use with a towing vehicle and a trailer frame equipped with hydraulic brakes. The trailer tongue (10) can be removed without disconnecting any of the components of the hydraulic system. A first guide (20) and a second guide (22) slidingly receive a tongue (10). A first end (12) of the tongue (10) is equipped with a non-active hitch (18) that connects to the towing vehicle. The second end (14) of the tongue (10) has an aperture (38) defined therein. A brake assembly (24) attaches adjacent to or on the second guide (22), and the assembly (24) has an aperture (36) defined therein. The tongue (10) is inserted through the guides (20, 22) until the aperture (38) aligns with the aperture (36) in the brake assembly (24). In order to connect the tongue (10) to the trailer frame (16), a pin (40) is inserted through the apertures (36, 38) in the brake assembly (24) and the tongue (10).
