W44 75/? M PUTQ/R United States Patent 3,138,230 WINDOW SILL STRUCTURES Walter M. Puto, Jr., 1035 NE. 127th St., North Miami, Fla. Filed Apr. 17, 1962, Ser. No. 188,147 2 Claims. (Cl. 189-45) This invention relates to building structures, but is more particularly directed to window sill structures.

A principal object of the present invention is to provide a window sill structure constructed of preferably extruded aluminum having a porcelain or baked enamel surface of any desired color.

Another object of the present invention is to provide a window sill structure with a window stool that may be readily replaced when it is desired to change the color thereof.

Another object of the present invention is to provide a window sill structure which is simple in construction, economical in cost and readily placed in position without the necessity of skilled labor or special tools.

A further object of the present invention is to provide a window sill structure that is suitable for all types of windows and all types of building construction.

A still further object of the present invention is to provide a window sill structure which is partially installed after the window has been placed in position and the window stool itself is not installed until all the construction work has been completed in the building thereby avoiding the possibility of damaging the finished surface of the window stool and the necessity of cleaning the stool after the plastering and painting has been accomplished.

With these and other objects in view, the invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming a part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure form the salient features of the invention as expressed in the appended claims.

In the drawings:

FIGURE 1 is a fragmentary cross sectional view of a window sill structure showing my window stool in position.

FIGURE 2 is a perspective view of a clip member.

FIGURE 3 is a fragmentary perspective view of a stool support member.

FIGURE 4 is a fragmentary perspective view of a window stool showing the obverse side.

FIGURE 5 is a top plan view of the window sill structure prior to placing the window stool in position thereon.

FIGURE 6 is a cross sectional view similar to FIG- URE 1 showing an alternate construction of the window sill structure.

FIGURE 7 is a perspective view of the stool support member.

FIGURE 8 is a perspective view of a window fastening clip.

FIGURE 9 is a fragmentary perspective view of the window stool showing the obverse side.

FIGURE 10 is a view similar to FIGURE 1 showing another alternate construction of the window sill structure.

FIGURE 11 is a perspective view of the window securing clip.

Referring to the drawings wherein like numerals are used to designate similar parts throughout the several views and in particular with FIGURES 1-5 inclusive, the numeral 10 refers to a cement block wall of a building at the position of a window 11 showing only its lower portion. Wood furring strips 12 which are secured to the block wall 10 support my window sill structure S as well as the usual rock lath 16 and plaster 17. Also forming a support for my window sill structure S is a poured cement sill 13.

My window sill structure S which consists of three major parts, namely, a window stool 20, stool support member 21 and clip members 22 is preferably fabricated of aluminum with a porcelain or baked enamel finish of any desired color or finish on the outer surface of the window stool 20. The stool support member 21 is an L-shaped extrusion having an upright leg portion 23 and a horizontally disposed leg portion 24 bevelled as at 25 at its free edge portion. Extending in an opposite direction from adjacent the top edge of the leg portion 23 is a T-shaped lug 26 for receiving a T-shaped slot 27 formed at one end 19 of the clip members 22. The clip members 22 are each provided with an elongated body portion 28 at whose free end there is a threaded bore 29 for receiving a leveling screw 30. A depending lug 31 projecting downwardly of the leg portion 24 extends along the full length of the window stool support member 21 and serves to strengthen the leg portion 24 against buckling and marks the position of the plaster 17. Elongated openings 32 are formed in the leg portion 23 for adjustably positioning the stool support members 21 on the wall 10 by means of screws 33.

The window stool 20 consists of a flat body portion 34 of a length equal that of the window sill and of such width to extend from the position of the front edge of the stool support member 21 to beneath the window 11 as shown by FIGURE 1. The window stool 20 is provided with a rounded front edge portion 35 at whose lower edge is a thickened portion for receiving a plurality of set screws 36 in threaded bores 37.

After the window 11 has been placed in position in the wall 10, a plurality of clip members 22 are slid into position on the lugs 26 of the stool support member 21 and the latter is placed on the inside surface of the wall 10. The stool support member 21 is levelled and aligned with the lower edge of the window 11 and then fastened by means of screws 33 to the wall 10. At this time, mortar cement is poured into the cavity found between the stool support member 21 and the window frame 11 to form the concrete sill 13. Then the window stool 20 having the desired color and finish is placed on the stool support member 21 with the outer edge of the window stool 20 slipped beneath the window 11 as shown by FIGURE 1. If the lower edge of the window 11 is not even or if a plurality of windows 11 are mounted together with non-aligned lower edge portions, the leveling screws 30 on the clip members 22 may be unthreaded to permit the head of the screws 30 to rise above the upper surface of the clip member 22. Then when the window stool 20 is placed in position thereon after all construction work is completed in the building the flat body portion 34 will be supported high above the clip members 22 in tight engagement with the lower edges of the windows 11. The set screw 36 is then tightened to secure the window stool 20 in position. The window sill structure S is now provided with a window stool 20 of desired color and finish which can be replaced by a similar window stool of different color and finish readily and economically when it is found necessary. At present, the Window sills being used do not play any part in the color scheme of the room since it is not replaceable when the room is redecorated.

Referring now to FIGURES 6-9 inclusive there is shown an alternate window sill structure S which consists of a window stool support member 38 having an upright leg portion 39 and a pair of spaced apart horizona

tal leg portions

40, 41 forming a channel 42. The lower leg portion 41 is provided with a plurality of threaded bores 43 for receiving set screws 44 and a depending lug 45 for strengthening the leg portions 41 and'marking the position for the plastering 17. The upright leg portion 39 is likewise provided with elongated bores 46 for receiving screws 47 to fasten the window stool support 38 to the surface of the wall 110 at the sill.

A plurality of clips 48 are fastened to the lower edge of the window 111 by a bolt 49 extending through the lower edge of the window 111 and a threaded bore in a flange 51. The flange 51 is mounted at right angle to the free end of a channeled portion 52 formed by returning the end of the main body portion 53 on itself in spaced relation to form a channel 54, The main body portion 53 is provided with a threaded bore 56 for receiving a levelling screw 57. A window stool 58 somewhat similar to that shown in FIGURES 1 and 4 and described hereinabove consists of a fiat body portion 59 whose free edge is received by the slot 54 of the clips 48. The front edge of the window stool 58 is bent at right angle as shown rather than rounded as in the stool shown by FIGURES 1 and 4 to form an angular front edge 60 with a flange portion 61 extending toward the window 111 and received by the channel 42. The set screws 44 are tightened and the window stool 58 is now held securely in position. The levelling screws 57 accomplish the same function as the levelling screws 30 described hereinabove in connection with the window sill structure S.

The sill structure S" shown by FIGURES l0 and 11 is identical to that shown by FIGURES 6-9 inclusive except for the structure of the clip portion 62. A different type of window 112 permits the fastening of the clip member 62 to a bottom wall 113 rather than the bottom edge of the window frame 111 as shown by FIG. 6 and described hereinabove. The clip member 62 consists of a pair of spaced

parallel leg portions

63 and 64 forming a channel 65 with the leg portion 63 greater in length than the leg portion 64.

Leg portions

63 and 64 are provided with threaded

bores

66 and 67 respectively. The threaded bore 67 receives a bolt 68 which extends through a bore 69 in the bottom wall 113 of the window 112 for fastening the clip member 62 securely to the window 112. The bore 66 receives a levelling screw 70 for maintaining the body portion 59 of the window stool 58 in firm engagement with the lower edge of the window 112 as explained hereinabove.
