' conveniently attached to a wooden building,

and it consists essentially of the improvements herein more particularly described and specifically set forth in the accompanying claims v Figure l is a plan view or my sill applied to a frame building. Fig. 2 is a perspective view of the sill by itself. Fig. 3 is a sectional view through the sill and wall. Fi 4 is a plan view of the board which I insert eneath the bed of my metallic sill. Fig. 5 is a perspective view of the form of my sill pref erably employed in connection with brick or stone buildings. Fig. 6 is a sectional view through the sill as applied to a brick building.

dicate corresponding parts in each figure.

Referring to the drawings, A represents the rough board sheeting of a frame building and B the finished covering of clapboarding usual in this type of building. This covering however, may be formed if desired of metal or other suitable form of finished covering well kn own to those skilled in the art.

C represents the window frame of the usual construct-ion and i. may here mention that in shipping these ndow frames from the factory it is necessary to temporarily nail a one inch rough board to the bottom of the frame which corresponds in shape to the sill which will afterward be placed below the frame. I make use of this rough board as an attaching means for my sill as will be hereinafter described. v

D is my improved form of hollow metallic sill which maybe constructed of any suitable metal that I consider preferable being crimpcd galvanized sheet steel of thickness from gage 26 to lit. The construction of the sill comprises a suitable bed a, slightly inclined to the horizontal, and from the upper Specification of Letters Patent.

in the drawing'lilre letters of reference in- Patented. June a, 1907.

ed e of which downwardly extends the front or meant I) of the sill which may be made flat or with any desirable molding or corruga tion. Integral ,with the bottom of the breast of the sill is an inclined flange c which is inclined slightly to the breast whereby the joining edge d will form a water drip for the sill. Integral with the inner side of this flange is a plate or flange f extending parallel -.with the wall of the building and which is adapted to be used in securing the sill to the building by being inserted between the sheeting and the finished covering. This flange preferably extends along the ends of the sill as shown and being securely held between the two coverings of the building will firmly hold the sill in position.

. Suitable end plates'e are provided at each end of the sill preferably being integral with the breast 1) thereof and simply bent into the required position. The horizontal-bed of the sill is not rectangular but has protruding portions 41 at each end thereof which extend laterally on each side of the window frame.

T 0 further assist in holding the sill in position the bed a thereof which is placed beneath the bottom member 9 of the frame has.

secured to the underside thereof the rough board it which as hereinbefore mentioned is temporarily nailed on the bottom of the frames as they come from the factory. Just before the frames areplaced permanently in buildings this board is withdrawn, placed in side the metal sill and secured by nails or other suitable means to the bottom member 9 and will thus hold the bed a of the sill se curely in position. The form of this rough board is indicated in Fig. 4 and it will be'seen. that it will extend completely under the horizontal bed of the sill.

. Referring to the form shown in Figs. 5 and 6 E represents the form of my sill comprising a substantially horizontal bed 7' integral with the inner end of which is a small upwardly extending flange 7c adapted to enterinto the groove provided in the lower member of the frame and so prevent any leakage of water.

through the sill. Integral with the outer edge of .the bed is an inclined water shed Z and integral with the outer edge of this is the vertically extending breast m of the sill. To tl e lower edge of this breast is secured the inwardly extending flange 7, the juncture o forming the water drip for the sill. Suitable end members 1) are formed integral with the breast To strengthen the sill I provide strengthening bars.

' the strengthening bars extend into the 'uncture between the lower, flange 'n, an the breast m of the sill. As many ofthese strengthening bars may beemployed as will be necessary to We the requireddegree of rigidity to the sil V In the sectional view in the drawin s the: line 22 represents the wall'line of the uildmg.

By the employment of special dies and machines to cut and form my sills in standard.

sizes they may be turned out very cheaply as articles of manufacture and by nesting them together great economy'may be carried out in the freight charges. The sill is practically indestructible as when formed of suitable metal there is no liability to rust or otherwise deteriorate. 7

lVlu'le I have described with great particularity of detail one specific embodiment of my invention vet certain changes may be made in'the cohstruction thereof within the scope of the appended-claims without departin from the spirit of my invention.

Vhat I claim as my invention is 1. A metallic window sill comprising a suitable bed an overhanging outwardly protruding hollow central portion integral there- .pose specified.

seaeee with and a flange integral with said central portion outwardly extending parallel with the wall of the building and adapted to be used to secure and hold the sill in its required position. as and. for the purpose specified.

2. In the window sill the combination with a hollow metallic sill comprising asuitable horizontal bed, an overhanging outwardly protruding hollow central portion integral therewith, of a flange outwardly extending parallel with the wall of the building and form'edintegral with the lower surface and ends of the central portion as and for the pur- 3. In a window sill the combination with the frame of a metallic hollow window sill having the bed thereof adjacent to the underside of the frame, of a board cut to fit the bed 'of the sill and secured to the undersidethereof and to the bottom member of the frame as and for the purpose specified.

4. The combination. witha hollow metallic window sill comprising a substantially horizontal bed and an overhanging outwardly protruding hollow central portion integral therewith, of an upwardly extending flange integral. with the ilmeredge of the horizontal bed and a plurality of strengthening angle irons secured to the underside of the sill as and for the; purpose specified.
