The objects of our invention are: 1. To

mediatesupports for thetrack cable. 2. To provide grips fort-he track cable to hold the same at the intermediate supports and prevent the lohgitudinal movement of the cable ,in said gripsiand tokeep the cable intact with itsintermediate supports. 3. To provide means toflrigidly anchoring the track cable'at intermediate points to prevent the longitudinal moyement of said track cable with respect to the earth; permitting, howe\'cr.a' slight-longitudinal movement of the between the a'oove rnentioned points. The said trackcible 'is to hold the intermediate .st1p'ports Lupright i fpeimitting. their tops to sway with the slight longitudinal movement of the said track cable.
