WINDOW STOOL.

Application led December 27, 192?.

My invention relates to buildings and par tieularly to a form of construction adapted for use in connection with the formation of window sills or stools. It comprises a sheet metal element or combination of elements so arranged as to provide for the reception oi a body oi' cementitious material that is moulded in place and constitutes a window stool. The arrangement is such that the plaster of the adjacent wall may be carried to the edge or' the stool and inished at that point without diliiculty, a plaster ground being provided for that purpose. ln the preferred form, the mould 'for receiving the cementitious material constituting the window stool is composed of two parts each oi which may be independently positioned and applied, thus enabling certain latitude in the previously installed construction elements.

The invention will be more readily understood by reference to the accompanying drawing, in which Fig. l is a sectional view through a window stool and adjacent construction, the' parts being arranged in accordance with my invention, and

Fig. 2 is a similar view of a slightly modified form.

In the construction in Fig. 1, 'the frame or support is indicated at 10, which may be of wood or masonry. A metal window frame is indicated at l1, and a window sash at 12. Metal lath 13 of the usual form may be applied to the wall and plaster 111 is laid thereon.

The window stool indicated at 15 is composed of a body of cement-itious material moulded in place and confined at its two edges by a pair of mould elements composed of sheet metal and each of angular toi-1n in cross section. The rear element is in form of a continuous angle, one leg 16 of which lies flat against the support, and is nailed or otherwise secured thereto. The other leg 17 extends vertically and lies alongside oit the Window frame l1. Its upper margin is rebent as at 18 to provide a key for the cement composing the window stool.

The forward mould element is also of angular form, the leg 19 of which lies Serial No. 242,631.

against the support and is nailed thereto, While the leg 2() extends diagonally upward and outward, terminating in a bead 2l, havlng a rebent marginal flange 22 that acts as a key. The bead is so arranged as to provide an undercut recess within which the plaster 14 may enter and which will act as a plaster terminal or key. The face of the bead acts as a plaster ground.

While l have shown the mould as com.- posed of two parts, it is obvious it mightbe constructed in one piece, but without the advantages attendant upon the use of the construction shown. In the form illustrated, the rearward mould element may be mounted flush against the window trame, regardless of the width of the support, with the assurance that the outer mould element may be positioned at exactly the required point in order to insure the proper thickness oi the plaster.

In the construction in Fig. 2, the support 23 and the window frame 2a are similar. Likewise the rear mould element 25 is identical with that illustrated in Fig. 1. However', the forward mould element is somewhatdiierent. It comprises a tlathorizontal portion 26 adapted to be nailed to the support, and a terminal portion 27 shaped to constitute a finish or decorative outline for the window stool. The marginal flange 25 is rebent to provide a key for the cement. At an intermediate point, the metal is doubled ou itself as at 29 to provide a key for the plaster and a plaster ground, and also to provide a shadow or break between the plaster' and the stool, as indicated at 30. This provides a desi able construction where a certain amount of exposed metal is not objectionable. lt is in addition some what more ornamental than the construction shown in Fig. 1.

Obviously other modifications than those described may be made and l do not wish to be limited. except as indicated in the appended claims.

I claim:

1. The combination with a sluoport., et a pair oitl mould elements adapted to be mounted on the support and to provide for a key with the cement constituting a windowV stool,

` the outer of said pair of elements being bent toprovide a key for plaster and a plaste ground. f

2. The combination with a. Window frame.

of arstool mould composed of a. pair of sheet metal elements adapted to be independently signature.
