IMPROVEMENT IN THE MANUFACTURE OF CORNICES.

Specification forming part of Letters Patent No. 159,494, dated February 9, 1875; application filed January 5, 1875.

To all whom it may concern:

Be it known that I, SIMON O. BRooK, of Watertown, in the county of Middlcsex, State of Massachusetts, have invented a certain new and useful Improvement in Oornices, of which the following is a description sufficiently full, clear, and exact to 'enable any person skilled in the art or science to which my invention appertains to make and use the same, reference being bad to the accompanying drawing, forming a part of this specification, in which Figure l is an isomctrical perspective view of the mold in which my improved cornice is formed; Fig. 2, a transverse section of the same, taken on the line .70 m, Fig. 1; and Fig. 3, a sectional view of the cornice.

Like letters of reference indicate corresponding parts in the different figures of the draw- 1n g.

Myinvention relates to that class of cornices which are-composed of fibrous or semi-fibrous materials, and molded or pressed into form, ready for use; and consists in a novel construction and arrangement of the parts, as hereinafter more fully set forth and claimed, by which a better article of this character is produced thanis now in ordinary use.

In most cornices of this description the substance of which they are formed is homogeneous throughout, frequently causing an absorption of moisture, and giving the parts a tendency to assume their normal position after being molded or pressed into shape. My invention is designed to obviate these difficulties and objections; and to that end, I construct the cornicein amanner which I will now proceed to describe.

To prepare the blank or material from which the cornice is made, I take a thin layer or "eneer of wood, and glue or cement it firmly to a layer or sheet of paper or card-board, and back the paper with another thin layer or veneer of wood firmly cemented thereto, or in such a manner as to bring the paper in the center of the blank, or between the veneers when the blank is finished. In cutting the veneers, and arranging the same in the blank, care must be taken to have the grains of the same run in opposite directions-that is to say, the grain of the face-veneer should be so laid as not to correspond with that of the back-veneerby which the tendency of the parts to warp and regain their original form after being molded will, in a great measure, be counteracted. After the blank is prepared, as described, the cornice is molded by means of a heated die-press, one form of which is shown in Figs. 1 and 2, consisting of the body A, having the cavity 2, into which steam is passed for heating purposes by means of the pipes c 0, through the connections b b. The top of the body Ais shaped to conform with the design or configuration of the cornice it is desired to produce, and a cap or die, E, corresponding on its lower face with the upper surface of the body, is fitted to the same, forming a matrix, in which the blank is placed and molded under pressure, as shown in Fig. 2, in a manner which will be readily understood by all conversant with such matters without a more explicit description. The blank should be slightly steamed before being pressed or molded; and it is preferable to use a water-proof cement in uniting the veneers to the paper.

I have found that a cornice having its center formed of paper, as described, is less susceptible to moisture than one composed entirely of wood.

Having thus described my improvement, what I claim is- As a new article of manufacture, a cornice composed of theveneer H, paper I, and veneer G, the grains of the veneers being arranged in opposite directions, and cemented to the paper, and the whole molded or formed in a heated matrix, substantially as and for the purpose specified.
