Abstract

339,182. Henderson, G., and Henderson, W. M. Jan. 29, 1930. Laying pipes. - In apparatus for laying field drains of the kind described in Specification 325,175, the tile driver comprises a link 1 which is provided with hooks 3 at its ends for attachment to the flexible haulage member 4 and carries a pair of dogs 5. The latter are adapted to engage the rearmost tile 2 of a train thereof when the link is moved in the driving direction A and to take up the position shown in dotted lines to disengage the train when the link is moved in the opposite direction. The dogs are carried by a member 8 which is adjustably mounted in a slot 9 in the link, and each is provided with a tooth 6 adapted to engage a rack 7 formed on the edges of the link to prevent endwise movement when in its operative position.
