Our invention relates to a cornice which may, for example, -be used on a window frame, and more particularlyto cornice construction whereby a cornice with vfiHiShGd COIH8IS may easily be produced. l

It has been common practice to-make the corners of cornices by miteringat a45 degree angle the'ends of the main or front partof the cornice and also the front ends of the return or bracket parts, so that the mitered :ends when placed :together will form a'90 degree corner. The mitering of the ends to be joined at right-angles. is frequently not accurate and the resulting joint is poor; for .example the'joint may not be -well closed. In other instances prefinished corners are .-.used. However, with :the last mentioned arrangement .thefront parts attached to the two corners must be connected-bye more .orriless unsightly extender which not only connects the ends but permits adjustment in lengthof the cornice.

It .is the principal" object .of ,our invention to provide .a cornice or cornice .constr-uctionwhereby it will be relatively easy for one to construct a;finishe d cornice by cutting oifas'uitable; length qt-cornice board and attachingtothe sameeat opposite ends, returns or. bracketportions of the cornice board, by. means of suitable finished cor.- ners.

Other objects of the invention will loe-here,-

{Iheparts so far referredto are well knownto those skilled in the art. According to our present invention, the front rail l-0 and-the returns H are connected' togethenby preformed finished corners l 2-which mayltake difierent:forms.--

Each of these corners l t-may comprise two parts or sides 13' of cornice-board-= accurately mitered as by -a machine ;securedlfirmly together by suitable means "which-may include reinforcing metal plates I 4: placed eat the tops and also the bottoms of said parts and secured firmly thereto, as by screws J5, to retain said parts :in

The invention will be described as embodied in a window cornice of which the front or rail 10 is a single piece of cornice board and the returns or bracket portions Ii are pieces of the.

In order for the corners l2 tofitcloselyover the ends of the rail and the returns, the inner faces of the sides [3 must be-formed vwithsuch onto rs .(Fia; 3) vwi l5:0 amem ntithe contour o a t e front face he r il. ,tther by enablin losely over adjacent en A illustr ted .in fi s: ....and A. th rail a .10- is cut with square ends and to the length equired hy-.th -.:width ...0 f the windqw rframe andv the thickn ss. of. het eturns-it l, andther orners are iplacedta hereon so that the ends ofthe rail abut against the corresponding sides of the corners. Then the forward ends of the returns II are inserted in the cornicecorne'rs l2 Withtheir ends abutting-against the inner sides of the ends of the rail 10. The parts thus assembled may be secured in position by screws l8 passing through suitable openings in the plates I4 and screwed into the members It] and II.

Although the illustrated embodiment of the inetii ns I ....asil ustratsd Y of each bracket being secured to a side of the window frame by screws 22 passing through a keyhole slot 23 and a lower opening 24 in such the returns to the rail including premade corners each with two sides and reinforcing means connecting said sides at the top, each of said corners receiving beneath said reinforcing means the front end of a return and the adjacent end of said rail.

3. A cornice comprising a rail of cornice board cut to length, returns formed from said cornice board, and premade corners receiving the ends of said rails and the corresponding ends of said returns, each corner having two sides with the ,same exterior contour as said cornice board and flange portion. The screws for the keyhole slots may be installed in advance and the cornice; hung thereon with the upper'screws 22 engag.

ing the upper ends of the keyhole slots 23. The

cornice may further be secured in place by other screws 22 passing through the lower openings.

All of the screws 22 may be tightened and the cornice strongly secured in fixed position.

. The present invention involves many advantageous features relating to the parts of the cornice and assembly thereof. The .return rnem bers or brackets ll may be made up in advance,

whereby the, only preliminary step to be performed on the job is to cut off a suitablelength of rail. Then the parts may be assembled to produce the final form shown in thedrawing. The corners are prefinished and conform to the contour of the board or the forward rail. The parts are held together with a minimum of connections. There is no unsightly extender for the rail, such as required in cornice constructions where there are rail sections extending inwardly from preformed corners and the adjacent ends have to be held together by extenders which connect the adjacent ends of the rail sections and, hold these. sections in alignment. Furthermore, the dealer or. consumer can make and install this particular cornice without millwork or special tools.

While the invention has been described in considerable detailand a preferred form illustrated, it is to be understood that many changes and modifications may be made within the scope of the invention as defined in the appended claims.

What we claim is: v

1. A cornice of the character described comprising a front rail of cornice strip material, returns, and means for connecting the returns to the ends of said rail including premade cornice comers into each of which fits the forward end of a return and the adjacent end of said rail.

2. A cornice comprising a rail of the requisite length of cornice board, returns formed from the same cornice board, and means for connectin the contour extending across the ends of said sides to merge in appearance with the front surface of the rail.

4. A cornice comprising a rail of cornice board, returns of such cornice board, and premade corners comprising sides and reinforcing plates connecting said sides at top and bottom, and receiving the forward ends of the returns and the adjacent ends of the rail, the forward ends of said Y returns being secured to said plates.

5. A cornice comprising a rail of cornice board, returns of such cornice board, and premade corners each having sides outside of the rail and returns, the outer surfaces of said sides having the same contour as said cornice rail and the inner surfaces of said sides having contours substantially complementary to the contour of the outer face of the cornice board to facilitate a close fit with the outer surfaces of the ends of the rail and the returns.

,6. A premade cornice corner for connecting the rail and returns of the cornice, comprising two sides having the same exterior contour as the said rail and returns, and reinforcing plates connecting the sides at the top and the bottom close to the edge of saidcorner.

7. A premade cornice corner for connecting th rail and returns of the cornice, comprising two sides having the same exterior contour as the rail and the returns, and an interior contour complementary to the exterior contour of said rail and returns.

8. A premade cornice corner for connecting the rail-and returns of the cornice, comprising two side pieces secured together, each of said side pieces having inside contours complementary in shape to the outside contours of the rail and returns of the cornice. 9. A premade cornice corner for connecting the rail and returns of the cornice, comprising two side pieces secured together, said side pieces having surface contours complementary in shape to the adjacent surface contours of the rail and returns to interfit therewith.
