this specification discloses a back and bail assembly adapted for ease of joining and separating the bail and back member . each of the two legs of the bail or handle includes a pintle or projection extending laterally to one side to be engaged by a recess in one of two opposing walls in the back member . at least one of the legs has a relief , or cut away corner , on the opposite side of the leg from the projection to facilitate insertion of the leg between the two opposing walls when the bail is in a generally lowered position parallel to the front face of the back member . however , when the bail is lifted and force is applied to pull the bail and back member outward , the full width of the front face of the bail is positioned between the opposing walls of the back member thus preventing accidental removal of the bail from the back member .
