Fig. 2 is a plates C. These spring members form terview showing the members uncoupled. Fig. minals of the other leads D of the'electrical 0 3 is a perspective view showing the members circuit and are movable relative to the fixed broken away and the two members uncouterminals C. The outermost ends of these springs or plates F project over the curved side faces of the blocks and are curved or bowed inwardly, and their tension is such as to normally carry the springs or bowed portions into contact with the curved surface of the reduced tongue or end portion of the blocks. Theextremeouterendsofthesprings are curved outwardly to a point beyond the plane of the side of the insulating-block or carrier. The width of the springs is conveniently substantially that of the blocks.
Located in the reduced portions of the blocks or carriers are terminal members consisting of the :metallic contact-pins H, the
outer ends of which rest against the plates 0, while the inner ends project into the recess E, for purposes presently to be stated. A suitable wear-plate h may be applied between the recess and ends of the tongues.
In use the construction and position of the springs and end of the carrier is such as to leave a substantially V-shaped space. The couplers on adjacent ends of two cars are arranged in opposite relation to each other,and when the cars carrying the carriers or insulating-blocks are brought together the opposite ends of the twin blocks will enter the V- shaped spaces, lifting the bowed-spring contacts and permitting an interlocking of the opposite curved surfaces of the members, a portion of each tongue entering the depression of the other. When so interposed intermediate the terminals, the twin-block insulating members of course open the circuit between the adjacent terminals D D of one coupler and establish circuits between the terminal D of each coupler and terminal D of the other. While in this position the curved springs rest forcibly on the sides of the plates 0, thereby forming an electrical contact of wide area. When the cars carrying the couplers are separated, the curved springs immediately snap down into contact with the interposed terminal pin H, thus completing the electric circuit through the pins as conductors. This is important in that an accidental breaking of the train will close the circuit on the broken section or individual cars, if it be such, and by well-known mechanism sound an alarm. It will be seen that the particular construction of the members is such that when they are arranged in opposite direction it will require but a single coupler at each end of the car in a manner similar to that of the ordinary car-coupler. It will also be observed that owing to the extended surface and the peculiar construction'of the couplers the two members can be moved to different angles relative to each other without breaking the electrical contact between the terminals. In turning curves the members are permitted a relative transverse movement by the particular construction of the bowed springs. Such movement will simply change the point of contact slightly between the springs and their contact-plates, but will not break the contact.
While the invention is particularly adapted for train-service, it maybe used for other purposes.
Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-
1. A coupling member for electrical conductors, consisting of an insulating carrierblock having'a reduced end portion, formed with a plane outer surface and a curved inner surface, a fixed terminal on the plane surface and a yielding spring-terminal on the opposite side of the block projecting over the curved surface of the reduced end portion, substantially as described.
2. A coupling member for electrical conductors, consisting of an insulating carrierblock having a reduced end portion, formed with a plane outer surface and a curved inner surface, a fixed terminal on the plane surface and a yielding spring-terminal on the opposite side of the block projecting over the curved surface of the reduced end portion and curved away from it at its outer end, and a conducting member connected to the fixed plate adapted to be engaged by the yielding, spring member, substantially as described.
3. A coupling member for electrical conductors, consisting of an insulating carrierblock having a reduced end portion, formed with a plane outer surface and a curved inner surface, provided with a wear-plate, a fixed terminal on the plane surface and a yielding spring-terminal on the opposite side of the block projecting over the curved surface of the reduced end portion andcurved away from it at its outer end, and a conducting member connected to the fixed plate adapted to be engaged by the yielding spring member, substantially as described.
4. A coupling member for electrical conductors, consisting of an insulating carrierblock having a reduced end portion, formed with a plane outer surface and a curved inner surface, adapted to interlock with the curved surface of a complementary reduced end portion, a fixed terminal plate on the plane surface and a yielding spring-terminal on the opposite side of the block projecting over the curved surface of the reduced end portion and curved away from it at its outer end, and a conducting member connected to the fixed plate adapted to be engaged by the yielding spring member, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
