ABSTRACT:
A base is provided including first, second and third adjoining marginal portions and a first stationary upstanding wall is fixedly secured to and projects upwardly from one of the marginal portions. Second and third upstanding walls are provided and pivotally supported along upstanding base edge marginal portions thereof from remote upstanding marginal edge portions of the stationary wall for swinging movement of the remote free upstanding marginal edges of the second and third walls toward and away from closely juxtaposed positions defining a peripherally enclosed upstanding mold cavity above the base between the first, second and third upstanding walls. The lower edges of the second and third walls are disposed in reasonably good sealed relation with the second and third marginal portions of the base. The base defines an upwardly opening socket centrally disposed relative to the cavity and an upstanding reinforcing member is provided and has its lower end received in the socket. An upper end portion of the reinforcing member includes a horizontally outwardly projecting shank supported therefrom and at least one of the free marginal edges of the second and third walls has a notch formed therein opening toward the free marginal edge of the other of the second and third walls through which the outer end of the shank projects. Horizontally aligned openings may be provided in remote wall portions of the mold and have the opposite ends of a horizontal sleeve projecting outwardly therethrough.
