JAMES W. CAMPBELL, OF BROOKLYN, NEW YORK.
WlNDOW-CORNICE.
SPECIFICATION forming part of Letters Patent No. 235,412, dated December 14, 1880.
Application filed October 23, 1880. (No model.)
1' 0 all whom it may concern:
Be it known that 1, JAMES W. CAMPBELL, of the cityof Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Adjustable Window-Gornices, of which the following is a specification.
My invention relates to adjustablecornices which comprise a center-piece, a back bar-or piece rigidly attached thereto, and wings which are adapted to slide longitudinally between the said center piece and said back bar or piece; and its object is to cheapen the construction of such cornices and enable them to be adjusted with less trouble.
To this end my invention consists in thecombination, in an adjustable cornice, of a centerpiece, a back bar or piece rigidly and permanently attached thereto, wings inserted between said center-piece and said back bar or piece and adapted to be moved longitudinally, and yokes rigidly attached to said wings and embracing said back bar or piece upon the back and upper and lower edges, whereby I provide a cornice which may be cheaply manufactored, and yet one which is very strong and may be adjusted with little trouble.
In the accompanying drawings, Figure 1 represents a plan of my improved cornice, partly extended. Fig. 2 represents a back view thereof; and Fig. 3 represents a transverse section thereof upon the dotted line w m, Fig. 1, and upon an enlarged scale.
Similar letters of reference design ate corresponding parts in all the figures.
A designates the center-piece of my cornice, and B designates a back bar or piece which is preferably of greater length than the centerpiece, and is connected or attached rigidly and permanently thereto, a projection, to, being formed on or attached to one part to keep the center-piece and back bar or piece at a required distance apart.
0 designates wings, which are inserted upon opposite ends in the space between the centerpiece, A,and back piece or bar, B, and are adapted to slide longitudinally in said space.
In order to hold the wings against movement transversely to said center and back pieces and against tilting relatively thereto, I provide yokes D, which are rigidly attached to the wings and receive within them or embrace the back bar or piece, B, which is of uniform transverse section throughout the whole or the greater part of its length. These yokes may be, and preferably are, composed of metal, such as hoop-iron, bent into the form of loops which have formed upon them outwardly-projecting flanges or feet I), for attachment to the wings, and which embrace the back bar or piece upon the back and upper and lower edges, holding it snugly against the back of the wings, as clearly shown in Fig. 3.
As also shown clearly in Fig. 3, the back of each wing is constructed with a ledge or shoulder, c, which, by the yokes D, is held snugly up against the lower edge of the back bar or piece, and this shoulder or ledge forms a smooth sliding surface-bearing against the said back piece or bar.
By shrinkage the back piece or bar may become reduced in width, and to prevent the wings from tilting orshaking I provide for adjusting the yokes D downward to draw the shoulder or ledge 0 up against the lower edge of the back bar or piece, B. This I do by making the holes in the flanges or feet I) of the yokes D elongated, or larger than the screws 61 inserted through them, so that by loosening and again tightening the screws the yokes may be secured in a new position.
The friction of the yokes D upon the back piece or bar is sufficient to hold the wings in position when adjusted, and to prevent the wings from being entirely disengaged from the back bar or piece I insert screws or pins 0 in the back bar or piece, against which the yokes D strike, and which form stops therefor.
In my cornice the wings have a long bearin g upon the back bar or piece, and hence cannot tilt or shake, and said wings will remain in the position to which they are adjusted without the need of securing devices.
I am aware that cornices have been made in which the wings are inserted into a tube formed in the center piece; and 1 am also aware that-cornices have been made in which the wings are held in place by being clamped between a center-piece and a back bar or piece detachably secured to said center-piece. I therefore do not claim either of these as of my invention.
W'hat I claim as my invention, and desire to secure by Letters Patent. is-- The combination, in an adjustable cornice, of a center-piece, a back bar or piece rig-idly and 5 permanently attached thereto, wings inserted between said center-piece and said back bar or piece and adapted to be moved longitudinally, and yokes rigidly attached to the back of said wings and embracing said back bar or piece upon the back and upper and lower 10 ed ges thereof, substantially as herein specified.
