JOHN CORREJA, OF BROOKLYN, NEW YORK.- Letters Patent No. 71,708, dated December 3, 1867.

IMPROVED rum-FRAME FOR GHIMNEYS.

TO ALL WHOM IT MAY consume;

Be it known that I, JOHN GORREJA, of, the city of Brooklyn, Kings county, and State of New York, have invented, made, and applied to use a certain new and useful Improvement in'Frnmes for Kitchen-Fireplaces; and I do hereby declare the following to be a full, clear, and exact description of the said invention, reference being bad to the annexed drawiug,-making part of this specification, wherein- Figure 1 is a sectional plan of the metallic frame, and

Figure 2 is an elevation of thejamb and section of the liutcl and throat-piece.

Similar letters denote the same parts.

Heretofore, in-building kitchen-fireplaces, particularly in cities, where ranges are generally introduced, it is usual to build up thcjambs and back of the fireplace of finished brick, and then place a stone lintcl across the fireplace, and then proceed with the ordinary coarse brick-work of the chimney and party-walls. Delay and difficulty are often experienced in getting the finished bricks and proper-masons to do this smalljob of finished brick-work, and when built, tlie angles are very liable to be injured, either by the setting of the range or by carelessness of workmen in constructing the building, and difliculty is experienced in keeping the fireplace.

around the range in a clean and tidy condition, corresponding with the rest of the kitchen, because the brick-work and lintel, whether painted or not are, liable to become soiled and damaged in use The nature of my said invention consists in hollow metallic jambs formed of cast-metal plates fastened together, and set up in their proper place, and secured by the brick-work built up within said hollow jambs at the same time as the rough party-walls, so as not to require the finished brick-work now usual; and I employ a castmetal lintel and throat-piece that take the place of the stone lintcl and of a sheet-iron stopper or throat-piece usually put up in the chimney, but which is liable to rust out and become loose, and thus lessen the chimneydraught through the range.

In the drawing, a b c are the cast-metal plates forming the hollow jamb into which brick-work or masonwork is to be built. 'These are to be of a more or less ornamental character. dis the cast-metal lintol, and e is a metallic backplate extending from one plate 0 to the other, andf is the throat-plate, with an opening and sliding damper, g; Said plate extends between the side plates cc, and from the back plate a to the lintel d.

It will now be understood that the kitchen-fireplace frame formcdof the plates aforesaid, is to be putinto the proper place on the chimney-piers, and then the chimney built up in and above such frame, and that it is strong, not liable to injury, adapted to the reception of the range, and to being painted or. enamelled to correspond in appearance with such range, and not liable to become soiled or injured.

What I claim, and desire to secure by Letters Patent, is-

Themetallicjambs for kitchen-chimneys, formed in the manner and for the purposes set forth; and incombiuation therewith I claim the metallic lintel, throat-piece, and back plate, as and for the purposes set forth.

In witness whereof, I have hereunto set my signature, this eighth day of AugustfA. D. 1867.

JOHN CORREJA.
