This invention relates to couplings for model gravity to the inner sideof the pivot ‘I and‘ the, railway vehicles and the like and has for its chief lever I comes to rest against a stop 8 asshown. object to provide for the automatic coupling in dotted lines, Figure 1. _‘ and uncoupling of model railway vehicles.

According to the invention, the automatic cou _6 to such agposition that its upper face forms pling and uncoupling of model railway vehicles, an incline from the inner end of the .platform_4 car and lorry trailers or the like, is effected by to above the top of the nose 3. V The coupling means comprising a lever supported approximate hook II is arranged so that as it is withdrawn ly vertically on a pivot in the coupling with suit able movement allowed in either direction from 10 from the gap platform 4 it raises up thetupper face of the arm 6 to just beyond the nose,3_ when the centre. it contacts with the shaped end of the army 6, and The pivot centre is on the vehicle side of a gap forces it and the lever I to again change their or opening in the coupling and below the level of centre of. gravity to the outer side ofpivot ‘I. the‘ bottom of said gap, whether formed in one The arrangement, is such that the .force re_-, casting or by a suitable platform over which an 15 quired to bringthe lever I from its inner to the. inverted hook forms the necessary’ coupling ar outer centre of gravity, e. g. from the position rangement. shown indotted lines to thatshown in fulllines, In order that the invention may be clearly is greater than the weight of the coupling, link understood and readily carried into effect, the same will now be more fully describedbythe 20 II carried by the adjacent, vehicle when resting on the coupling.
