A telescopic tow chain comprising spaced apart upper and lower links joined by means of vertical pins further includes slotted connecting links. The upper links have tapered leading and trailing edges which are able to slide above or below the adjacent upper links thereby permitting the chain to compress as the vertical pins slide together in the slotted connecting links permitting the chain to drive on the return run as well as on the primary run and eliminating the necessity of a takeup mechanism. |
