FIREPLACE-(SMOKE cHAMBER .oons'riauorron- Application filed December 31, 1928. 7 Serial No.329,373."-
The properconstructi'on of a fireplace is one requiring considerable skill'and as fire places are ordinarily constructe-d'it' is often 1' dificult'to properly proportion and construct a the necessary passageways so as to to secure thebest results. The principal difficulty in suchxconstructionris theformation of the smoke. chamber or part that connects the fire box with the flue. 'Usually thefireplace'has so to be "completed afterthe walls and other parts 'of the building are finished so that it is dificult for the'mason to have access to the passageway or .to 'readily fashionthe" surrounding walls to leave .asuitably shaped" l smoke chamber. v The objects of this inventionare'to" provide means foriforming a substantially."perfect connection betweenthe firebox and the'fiue or chimney; toiprovide a form or frame work 120 which will indicate-or insure the proper shape for the smoke chambergitoprovide a metallic frame. worknto be iused in building a fireplace connection; to provide 'a'fireplace having a smoke-chamber which is properly constructed and arranged to provide proper draft for the fireplace and also to provide means whereby any down draft in the chimney will be controlled or prevented from causing smoking; to provide a chimney in smoke chamber or connection between the fire box and the flue having suflicient space at the back of the opening from the fire box to permit any down draft to be returned up the flue; and to provide such other desirable features :2; and improvements in construction as will be described hereinafter.
In the accompanying drawings illustrating this invention.
Figure l is a front view of a fireplace show- 12 ing our improved construction;
Figure 2 is a sectional view taken on the line 22 of Figure 1;
Figure 3 is a front view of'our improved frame or form used in making the smoke .3 chamber;
Figure 4 is a back view of the same; and
Figure 5 is an end View of the same.
The fireplace shown in these drawings com prises a fire box 6 having a back wall 7 and in end walls 8 and has an outlet or opening 9 leadinginto theismokechamber "10, This opening which is usually long and narrow is preferably controlled-by means of a damper 11 which may be of'any ordinary or preferred constructlon; and is shown as being hinged at l2along the back of theopening;
The smoke chamber forms the connection ticularly relates. In order to properlyform between the fire box 6 and the flue or chimney '13 and is the part to which this invention parthis chamber; we provide a frame 14, as shown particularly; in Figures f 3, 4 and '5. This frameflconforms in general to the proper shape for the smoke'chamber and is pref erably formed of angle iron orthe' like. "It comprises ends 15, each of which hashorizonablyarrangedso that bricks'will'fit between tal top angles16 and bottom angless l7. The angles or bars 16 andl7 are connected by posts or connecting members '18 each" of these being formed of two angle irons andpre'ferthe fanglegirons ,andibe sup-ported thereby.
The P angles are fastened together-at the 'back'by a bolt 19 anathe lower angles i by a 'back cross pieceor angle 20. The lower angles 17 are preferably: provided with out wardlyprojecting straps or supports 21 to assist insupportmg' the frame on thebrick Y work. The frontr22 comprises end-bars or angles 23 which are pivoted at 24 to; the top bars or angles 16 and areconnectedby bolts tend through slots 26 in theangles 23 and slots 25 to thebottom anglesl'i. 5 The bolts 25 ex--a- 27 in theangles-il'l "in order to permit the" adjustment'of the angle of the front frame member; The angles 23 are connected at the top by angles 28 and at the bottom by angles 29. "The angles 28 and 29 are further -con-' inected by bars or uprights 30. Each of these a is preferably formedof a pair of angles and '90 they'are spaced so that they provide sup of theiframe is substantially vertical while the ends andfront are. arranged at the angles of approximately-sixty degrees,i-:whichl has.
been found a desirable pitch for the corresponding walls of the smoke chamber. The front of the frame may be adjusted to permit variation in the depth or distance from the front to the back of the smoke chamber and also for variation in the width of the opening from the fire box.
In the construction of a fireplace with our improved frame or form, the brickwork is preferably carried up to approximately the top of the back arch and to the bottom of the smoke chamber, for instance, as indicated in Figure 2. The frame is then placed in po sition with the bar or angle 32 resting on the bottom of the smoke chamber and the straps or supports 21 may be supported on the brickwork at the ends of the fireplace. The end and front bricks may then be placed in position on'the ends and front of the frame and the adjacent brickwork then carried up in the usual manner until connection is made at the top of the smoke chamber with the flue lining 33 which completes the connection betweenthe fireplace and the flue. By means of this arrangement it will be seen that the smoke chamber will be properly proportioned and the walls thereof may be made smooth by any brick layer or mason, even if he has no particularlyskill in the construction of the places. Furthermore, on account of the downwardly projecting legs 31 and cross bar 32, a space must be provided at the rear of the smoke chamber which extends downwardly to the bottom of this support which will preferably be below the pivot 12 of the damper 11.
With this construction, it will be seen that we not only provide a suitable connection for the up draft from the fireplace to the flue, but we also provide a space at the back of the smoke chamber so that if there is any down draft at the back of the flue or chimney, which is often apt to occur, the air will follow the directions indicated by the arrows so that when it strikes the shelf or bottom of the smoke chamber it will tend to be deflected upwardly at the back of the damper to oin with the upwardly moving gases from the fireplace. This eflfectively prevents any down draft from causing smoking of the fireplace or blowing of the gases out into the room. While the damper may assist in directing such air upwardly, our construction would effectively prevent smoking of the fireplace, even if no damper is used.
Our improvement may be varied in the details of construction in order to adaptthe same for different fireplaces or different conditions, and changes may be made within the spirit of this invention without departing from the scope thereof as set forth in the following claims, in which we claim:
1. A frame for constructing a fireplace smoke chamber, comprising ends formed of angle iron and converging toward the top, means forrigidly securing the ends together,
an adjustable front formed of angle iron and sloping from the bottom toward the top, said ends and front being adapted to receive bricks, and a downwardly extending frame member adjacent to the back which is adapted to rest on the smoke shelf.
2. A frame of the character set forth, comprising end members, means for securing the end members together, a front pivoted to the upper ends of the end members, means for adjustably connecting the front to the bottom of the end members, brackets extending outwardly from the end members, and a supporting bracket extending downwardly at t back of the frame.
3. In a fireplace construction, the combination of a fire box having an outlet at the top,
apart at the top and diverge downwardly, a
fastening member for fastening the end members together at the back thereof adjacent to the top, and a reticulated front which is pivotally connected at the top to the end members whereby the front may be adjusted with respect to the end members.
