SMOKE-CHAMBER LINING.

Application filed January '26, 1927. Serial No. 163,627.

The object of my invention is to providemeans to permit the ready construction of a smoke chamber above a fireplace in communication with a chimney flue, whether the greater diameter'ol the flue be parallel with the greater diameter of "the fireplace or at right angles thereto, whereby the masonry,

brickwork orthe like may be built up along the sides of the smoke chamber in a proper manner and the sidewalls of the smoke chamber will be smooth. p

In carrying out m j'invention I provide plates to belocated within the masonry or brickwork over a fireplace to 'provide the side walls of a smoke chamber, with a collar adapted to be attached to the upper ends of said plates to register with a chimney flue whereby said plates are secured together to .per1nit the building of the masonry therearound, whereby to provide a smoke chamber above the fireplace of the chimney, the plates serving as a lining for the sides of the smoke chamber. A feature of my invention is thatthe smoke chamber plates are pro- "vided at their upper ends with sections-detachably secured to the plates and of such dimensions respecting the collar that When the latter is to register with a'flue that is parallel with the longest dimension of the fireplace the sections willfibe detached from the plates and the latterwill be attached to the collar alongthe narrow dimensions of the latter. whereas when the greatest dimen sion of the flue is at a rightangle to the. greatest dimension of the fireplace the plates with the attached sections will be secured to the collaralong the greatest dimension of the latter. In either case the masonry may be built around the smoke chamber plates as desired.

A further feature of the invention isthat the lower ends of the smoke chamber plates are located at an angle with respect to the planes of the plates so as to be fitted over or against the upper portion of a damper located in an ordinary way within the masonry over the fireplace whereby the smoke chamber plates will be sustained by the masonry or damper.

My invention comprises novel details of improvement that will be more fully here inafter set forth and then pointed out in the claims. I 7

Reference to be had to the accompanying drawings forming a part hereof, wherein Fig. 1 is a partly broken front view illustrating my improvement in a fireplace;

Fig. .2 is a vertical section;

Fig. 3 'is a perspective View illustrating the parts of my improvement "in position for use in a fireplace according to Fig. 1, and

Fig. 4L illustrates my improvement for use with the greater diameter of a flue at right angles to the greater diameter of the fireplace. I p ,7

Similar numerals of reference "indicate corresponding parts in the several views.

The smoke chamber plates indicated at 1 and 2 may be made of sheet metal and detachably connected at their upper ends with a collar 3 which is adapted to register with a chimney flue. I have indicated a chimney flue lining at t but the flue may be built directly in the masonry for brickwork of a chimney in any well known Way. The collar 3 is shown rectangular in shape, longer than wide, to correspond with the usual The smoke dimensions of chimney v fl'ues. chamber plates 1 and 2 diverge downwardly from the "collar 3 to provide the side walls of the smoke chamber 5 in an upwardly converging manner above the fireplace 6, for which purpose the upper edge portions 1 2 of the plates 1 and 2 are'bent at an angle the adjacent portions of the collar 3 in a vertical direction. The end portions 1 '2 are provided with holes to receive bolts 8" that pass through 'holes 9 the collar for securing the collar and platesftogether. The

collar may be made of a suitable piec'e'of metal'bent to the desired rectangular shape providing outwardly disposed flanges 3 to be embedded in the brickwork or masonry of the fireplace, (Figs. 1 and 2), to aid in supporting the lining 1 and in supporting the plates 1 and 2. The upper end portions of the smoke chamber plates 1 and 2 are provided with detachable sections 1", 2", shown in triangular form, having their bases adjacent to the collar and their apices adjacent to a side edge of the corresponding smoke plate. The sections 1 2 are shown having their outer edges substantially parallel with the corresponding outer edges of the plates 1, 2 and their inner angularly disposed edges opposing corresponding angularly disposed edges 1, 2 of the plates 1. 2., whereby the sections and plates are fitted edge to edge. The sections are shown proto theplane of the plates so to bearagainst 3 When the sections 1", 2 are removed from the plates 1, 2 the width of the upper ends of the plates will be approximately the same as the width of the narrow ends of collar 3 so thatthe plates will be attached at their upper ends along the said ends 01 the collar to be fitted inthe fireplace with the greatest length oi the collar extending in the direction of or parallel with the greatest length ofthe fireplace, and with the plates 1v and 2 diverging downwardly, as illustrated in Fig. 1. lVith the sections 1*, 2" attached to the plates 1 and 2 the complete width of the sections with their plates will be approximately equal to the greater length of the collar, t), so that when the collar and the plates are located within the chimney the greater length of the collar will extend in a direction substantially at right angles to the greater length of the fireplace with the'plates 1, 2 diverging downwardly.

The lower ends of the plates 1, 2 may be rested upon the masonry or brickwork, or may be fitted in conjunction with a fireplace damper of any desired or well known variety, indicated at 12. The lower end portions 1, 2 of the plates 1, 2 are shown extendng at an angle to the plane of the plates, such. portions of the plates being adapted to be adjacent to the top edge oi the damper and spaced wider than the damper so as to extend slightly outside of the ends of the damper at the top to be rested upon the masonry or brickwork in a substantially Vertical position in such a way that the damper plate or valve 12* may swing within the portions 1, 2 of the smoke plates, as illustrated in Fig. 1, and the smoke will be conducted from the fireplace or the damper between the smoke plates up to the chamber therein above the fireplace, communicating with the flue, having upwardly converging side walls serving to aid in creating an upward draft to the flue and to resist the deposit of soot. The construction described assures a smooth interior at the sides of the smokechamber at the ends of the bricks outside thereof of proper shape causing proper alignment of the flue lining, thereby 1 preventing a mason from inaccurately installing bricks along the portion of the fireplace or flue just above the fireplace.

Having now described my invention .what

I claim is 1. A fireplace smoke chamber lining comprising a collar having greater length than width, a pair of plates adapted .to be secured thereto at the upper ends, the collar being arranged to registerwith a chimney fine with the plates diverging downwardly from the collar, the plates being provided with detachable sections at the upper por tions alongcorresponding edges, andlmeans for detachably'securing the sections to the plates, whereby the plates and sections may be secured to-the greater length of the collar' and the plates without the sections maybe secured to the lesser width of the collar.

2. A fireplace smoke chamber lining asset forth in claim 1, in which the sections have outer edges substantially parallel with corjacent thereto being located at an angle to the first named edges of the plates.
