By this simple means the train remains intact as long as the cars or locomotiveremains upon the track; but in event of one or more cars leaving the track the derailed car will be automatically released and not drag the other cars with it.

The device is very simple in construction, easily applied and operated, and will be very efficient for the purposes described.

Having thus described myinvention, what I claim is- 1. A car-coupling consisting of a head having spaced jaw members contracted at their terminals, an opposing head member engaging said contracted portion and provided with an enlarged terminal engaging the space between said jaw members, and rods connecting said jaw members upon opposite sides of said opposing head member, and preventing lateral movement thereof but breakable under abnormal lateral strains to release the opposing jaw member, substantially as described.

2. A car-coupling consisting of a head having spaced jaw members one of which is provided With a rib extending toward the other jaw member, an opposing head member having a rib extending from its extremity and adapted to engage the rib upon said spaced jaw member, and breakable rods connecting said jaw members upon opposite sides of said opposing head member, substantially as described.

3. A car-coupling consisting of a head having spaced jaw members and a concave recess between said jaw members at their innerends and one of said jaw members being provided with a rib extending toward the other jaw member and rounded upon its outer surface concentric to said concave recess, an opposing head member having a shoulder engaging the rounded outer surface of said rib and with a rib upon its extremity having convex surfaces adapted to alternately engage said concave recess and the inner surface of said spaced jaw-rib and breakable rods connecting said spaced jaw members upon opposite sides of said opposing head member, substantially as described.

4. A car-coupling consisting of a head having spaced jaw members contracted at their terminals and adapted to be detachably connected to a car, an opposing head member engaging said contracted portion and having an enlarged terminal engaging the space between said jaw members and adapted to be detachably connected to the next car, and rods connecting said jaw members upon opposite sides of said opposing head member, and breakable under abnormal lateral strains, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence ot' two witnesses.

JOHN SINES.
