LOUIS RICHARD HOLLOWAY, OF VICTORIA, TEXAS, ASSIGNOR TO CABIBANGE 'MANU- FACTURING COMPANY, OF BELLEVILLE, ILLINOIS,A CORPORATION OF ILLINOIS.

` STOVE AND RANGE.

Asign a range and cabinet, in which the compartments are tl'ioroughly and evenly heated and in which the compartments are substantially thermally independent of each other, the uniformity in temperature being obtained by a particular flue arrangement and a reticulated baille plate, the thermal independence being produced by the presence of a two-way damper properly positioned, 3, to design a seli locking damper4 for directing the passage of heated air through a multiplicity of iiues.

With the above and other objects in view, my invention has relation to certain novel features of construction and operation, eX-

amples of which are described in the following specification .and illustrated in the accompanying drawings in which;

Figure 1 is a longitudinaly cross-section through the center of the range and, Fig. 2 is a front elevation of my locking damper in an open position and, Fig. 3 is a Jfront elevation of my locking damper in a closed position and, Fig. 4 is a perspective view of the locking plate used in connection with my locking damper and, Fig. 5 is a perspective view of my reticulated baile plate.

In the drawings numeral 1 designates a horizontal base frame, supported at its corners by the legs 2.

3 designates a rectangular fcompartment; at its left is the ash pit 4 and immediately above thecompartment 3 are thecompartments 5, 6, and 7. Immediately at their left the compartments 8 and 9 are situated. Above compartment 5 is compartment 10 which is surrounded by the ilues 11, 13, 11 and 15. To the lett of iiue 11 is located flue 12.

16 designates a two-way stove damper, 17 a reticulated balile plate and 18 the eX- ycoal pouch. f

aust ,flue leading to a conventional smoke 19y designates the stove plates and 20 the 21 designates a conventional shaker grate and 22 a iire back.

The shape and lpositioning of the compartments as well as the walls and joint structures for the walls are of the accepted type and design. Walls are made of a par* ticular composition of iron and where linsulated are made of alternate sheets of asbestos andiron. Thewalls 23, 211,25 and 30 and the backs of compartments 6, 7, and 10are insulated. Y

Coal isk placed in the pouch 2O through the door 26 from which it feeds to the co1nbustion chamber 9 resting on the rocker grate 21.l The ashes are precipitated into the ash-pit 41. The products of combustion arise from the combustionV chamber 9 and following the arrows along the flue 15 arrive in the vicinity of the damper 16. From this'point, by placing the damper 16 in a horizontal position so as to obstruct the passage into flue 12, the gases are compelled to take the circuitous path indicated by arrows through flues 15, 14, and 13 respectively, and thence out the stack 18, or u the more direct path through flue 11, through the reticulated baiile plate 17 into the flue 13 and thence into the stack 18. The retieulated baflie plate 17 consists of a rectangular sheet of metal' with perforations or reticulations. Thevpositioning of this baille in the path of the gases coming through flue 11 makes possible the uniformity in temperature in compartment 10 styled the bake oven. The success of a bake oven depends on its uniformity or evenness of temperature. This is brought about by the entire envelopment of the oven bv gases at substantially like temperatures. In the absence of the battle, the products of combustion, taking the line of least resistance, and owing to their lowest speciiic gravity would all practically rise through theflue .11 and pass out stack. l18 via. flue 13. This would heat wall 28, and by conduction the air in the left side 'of the oven 10, thereby producing a condition only too prevalent in the present type of range. By the proper proportioning of the sizes and distances between the openings in the batiie plate 17, a sufficient resistance can be introduced into the path of circulation through the flue 11 to cause the required amount of heated gas to take the circuitous path 15, 14, and 13 around the bake oven 10. By an empirical investigation, the design of this baliie can be made to producean even balance in the amount of gas that travels through flue 11, and through flues 15, 14,

,and 13. Y

When it is not desired to heat the oven 10,

the damper is brought to a diagonal position and 7. e

7 vshows a` pan in position as held by the two ledges 31 and 32. The space occupied byv 6 and 7 is heated by conduction through the metal of the lire back 22 and lthrough the vlower surface of the'fiue 15 and thence by convection through air currents in the compartment 8. Warming closet 5 receives its heat from the walls 30 and 33. Compartment 3 receives its heat through the walls 34 and 35.

Although the construction shown in flue 11 with the reticulated ba-ie plate 17 is my preferred form, I do not wish to be limited to it.

My locking damper consists of a rectangular plate 36, two end plates 37 and 38 and a conventional handle. Plate 38 has a notched bearing 40 on which the shaft 41 is permitted to rotate, when the damper is in position.

42 is a rectangular projection made integral with plate 38 and at a definite angle with the side 44 of the plate 38; the upper face of projection 42 being horizontal when in position, and flush with the lower edge of the bearing 40.

43 is a substantially triangular projection at a definite angle with projection 42 and also made integral with plate 38.

45 designates a nose extending slightly' above the upper face vof the plate 38.

46 represent holes by which the plate is fastened securely to a particular stove element.

Qopiel of this patent may be obtained for At` one extremity of plate 36 isV formed the groove or dish 47 parallel to the edge of the plate 36. Plate 37 is rectangular in shape, has no projections, and a notched bearing 48. The distance between the right edge of plate 38 and plate 37 is sufficient to permit of a lateral motion equal in length to the width of projection 42.

The operation of my damper is as follows: Consider the damper in the position shown in Fig. 3, with the left edge of plate 36 resting on the upper surface of projection 42 and the left endjof plate 36 immediately adjacent, the inner surface of plate 38. Upon rotating the damper in itsv journals 41 and 48, toward the p osition shown in Fig. 2, the left edge of plate 38 meets thefeather edge of projection 43, and then moves up the edge of said projection 43, thereby moving the entire damper laterally to the right. Vhen the edge'of plate 36 reaches the nose 45 of projection 43, a slight lateral movement of thedampery to the left causes the notch 47 to engage the nose 45, thereby locking the dam` yper in this condition, as shown in Fig. 2. A

slight movement'upward and thence to the right will disengage the damper and permit ofrotation to its normal position shown in Fig. 3. By this means, the damper is locked in one position by the nose and notch engagements, and in the other, shown in Fig. 2, by lying flatly on the projection 42. The weightof the damper produces this effect.

In a range of the character described, an oven whose walls are spaced from the walls of the range to form thereabout heat ducts, the first of which forms a direct passageway from the source of heat to the heat outlet the secondl of which envelops said oven, andv thermal equilibrium in the ducts enveloping said oven.

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.
