BAKERS OVEN.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed January 9, 1907. Serial No- 351,495;

To all whom it may concern.-

Be it known that I, CLARANOE W. HELLER, a citizen of the United States, residing at Galva, in the county of Henry and State of Illinois, have invented new and useful Improvements in Bakers Ovens, of which the following is a specification.

This invention is a bakers oven and its object is to form an oven of cheap and simple construction, characterized by an absence of complicated and expensive flues under or over the baking chamber.

A further feature is that the ascending and descending flues are both made at one side or corner of the structure, on the side opposite to the fire box.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a front elevation of the oven. Fig. 2 is a section on the line 22 of Fig. 3. Fig. 3 is a section on the line 3-3 of Fig. 1. Fig. 4 is a vertical longitudinal section on the line 44 of Fig. 3.

The oven comprises a substantially rectangular structure of brick work, the walls of which are indicated at 6, inclosing the baking or oven chamber 7 which receives its heat directly from the fire place at 8. This fire place is located at one of the front corners of the baking chamber, and has thereunder an ash pit 9 for the removal of the ashes. The baking chamber has a door 10 at the front, as well as the usual light hole 11 and other well known appliances useful in connection with the oven.

At the front corner of the oven opposite to the fire place 8 is the down flue 12 which communicates at its lower end with the front end of a longitudinal flue 13 which extends thence to the back of the oven and communicates with another longitudinal flue 14, which is connected at the front end to the up flue or stack 15 located at the front corner of the oven wall. The return flue 14 may contain a coil for heating Water, as at 16. The

flues

13 and 14 are provided at the front with cleanout doors 17 and 18.

The back and forth

flues

13 and 14 are readily constructed of brick work arched to support the weight of the parts above. Heat is communicated therefrom to the bottom of the oven chamber, without the complication of a large number of back and forth flues extending under the bottom, which are costly in construction and difficult to keep clean. The heat supplied by the fire place passes through the baking chamber and to the down flue 12, and thence back and forth through the

fiues

13 and 14 to the stack. The fiues are of large size so that they will not readily clog, and can easily be cleaned out upon occasions.

In ovens of this kind the side of the baking chamber opposite to the fire isthe cold side or part of the oven. The present invention remedies this by providing the hot air fiues under said side of the oven, thereby equalizing the tem erature therein. It is obvious that if the ues under the Whole of the oven were continued back and forth under the whole chamber, the defect would not be remedied, because the floor of the oven would be uniformly heated and consequently the excess of temperature would still exist on the side of the oven toward the grate. By extending the flues under one side of the oven only, being the side opposite to the fire, the difference in temperature is corrected and a substantially equal heat throughout the oven is assured. Furthermore, an advantage results in having the up and down flues in the front corner of the structure, as it brings the heat to said corner and thereby balances the heat of the fire box in the opposite corner; and the up and down fiues, and the fire box, being both located in the front of the structure, makes the oven somewhat hotter at the front, which is proper, because the bread in the front of the oven is the last in and the first out.

I claim:

1. A bakers oven having a fire place at one front corner of the baking chamber, down and up flues at the other front corner, and backwardly and forwardly extending flues under the baking chamber and communicating respectively with said flues.

2. A bakers oven having a fire place in one corner of the front wall of the oven and down and up flues in the other front corner, and a brickwork structure extending partly under the baking chamber and having backwardly and forwardly extending fiues therein communicating respectively with said up and down lines.

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