The present invention relates to what I longyto allow. the chain 15. to hang out of call a bell for a conduit, and has for its prin- 't-hebell attachment as is clearly indicated in cipal object to provide a device which may be Fig. l inserted in the end of a conduit while the The idea of this bell is to make a larger conduit is being encased in concrete for proentrance for the cable in the manhole.

It is apparent that the changes in the details of construction, and in the combination and arrangement of parts maybe re-.

Having thus described my invention, what I claim as new is 1'. A core for forming a depression in concrete about the mouth'of a conduit that is to be encased in concrete'comprising a hollow frusto-conical body having the smaller end adapted to be inserted in the end of a conduit while the concrete is being poured aboutosaid conduit, a barextending acrossthe opening at the larger end of said body havingmeans thereon adapted for attachment to the form in which the concrete is poured, a bar across the smaller end of the body and means secured to the last men- 7 tioned'bar and extending outwardly through the opening in the body for pulling vthe body out of the concrete-after the latter has set. 7
