To all whom it may conberm Be it known that 1, Joris .1Acois PFnNNiN-' t. Louis, State of Missouri, have invented certain. newl and useful Im-y proveniente in Bake-Ovens,of which the'folfull, clear, and exact description, reference being had to theA accompanying fire box underneath the lioor 6, as best shown in Fig. 1. 'f The baking compartment. entends entirely through the oven,and is open at both ends, the walls'2 being provided withA openbake pans 10. A

Resting on the bottom iloor G are -shaped tracks 11 ou which the bake paus-10 restanti are adaptedto slide, by which construction the pans are guided through theoven and the material or' dough to be baked is, thus guided and suspended above the floor of the baking compartment..

he tracks 1 1 h thereof by means of bolts pieces 13;, and pivotally mounted on said cross-pieces 13v are chain wheels 14, and mounted on said chain-wheels is an endless chain 15 which is provided with a series of holes 16. Two of the chain-wheels 14 are located one at each end of the bakingchaniber. 7 and the other two are' located alongside My invention has relation to improvements in bakeovens-and consists in'. the novel ar rangement `and combination of parts more fully set forth in the specification and pointed In the draw-ings,Figure 1 is avertical lon-l itudinal mid-section of my complete invenave secured tothe ends the line 'f of Fig. 1.

Said doors maybe elevated and secured in said elevated 1o position by means ot` hooks l22 as illustrated .-ln Fig. 1, and in fact I always bake with the doors in said elevated position. In starting the tire of cou-rse the doors areclosed so as to retain the heat imparted to the baking com- .I I5 partment.

23 represents the top Iwall of the baking compartmentvwhich extends entirely across the bake oven, the said wall being composed of fire brick or anysuitable material.

Located directly above the door 23 is a line 2 4 for the passage of thep'roducts of combustion, and located above this 'iiue is a wall 25 similar to the wall 23, above which is a flue 26 similar. to he flue 24, covered by a top z 5 wall 27. y

The filles 8, 24, and26, are designed to con'- vey theheated a take-u p due 28 of the lconstruction as illus- -trated or its equivalent. -Said take-up fines are in communication with the dues 8, 24, and 26, the rear take-up dues/however having no direct communication with the flue'26 at that 4o end. The object of said fines 28 istore'gn late the temperatureof the bakeoven, and properly through the oven. Said dues 28 are provided with cut-oit dampers 29, and'these dampers may enter into the 'iluesfrom the sides of ,the

oven or from the ends as'shown,A

Located at each in the central portions thereof is an exit and take-up flue 30;' or in'other words V,there are 5o two exit and take-up fines such as 30, one 1o- ,cated at .each end dues 30'are provided with dampers 31"*and 'communicate with the flue 26; the one'at'the front end of the bake oven communicatesalso `'dir'ectlywt'h'the fire-box through th'emediun of the dues 28 at the front and the frontend' o f the ilueiiihthatis Vto say, there willbe a substantially direct upward communication between the fire box and theft-ont exitfluebeyond'theaopwall epee. .said nues so'extsmi 2T of the -bake oven to any suitable andconvenient distance,- as shown in Fig.'1. f 4.

It may be noted that I can construct my bake oven of any size; but the one nowrused by me is vabout five feet in width, exclusive of the Width Vol. the dues, and about ten feet in length. The bake oven should be made vsuiiciently long so as to accommodate the insertion of quite a number of bake pans, in theV baking chamber 7 thereof. One ot the chain wheels 14 has secured thereto a crank 34, by

decrease y the temperature of said door 33 for the insertion and removal of the i' which the vsa'me may be rotated, and conse- 15 for the removal and carrying through the baking chamber of thebake pans'lO. r Each of the bake pans is` provided with a lue: 35 whichl is adaptedto be inserted in ythe perforations 16 of the endless'chain 15.

By means of the exit dues 30 aud the takeup dues 28 the temperature of the bake oven` may be controlled inv a manner' as I will now When the fire is first started in the bake oven, and in order to heat the same throughout, I close the dampers 3l and 29 of the lueslocated at the righthand of Fig. 1 or the front of the bake oven. By

the heat and the products of combustion are not led directly out,

of the bake oven through the front fines, butare caused to pass throughout the dues 8, 24, and 26, that is to say,-they pass backwardly. through due 8, then upwardly into the flue 24 through the reartake-u p ilu-es 28, then forwardly through the flue 24, then upwardly into the due 26 through the front take-up fines V8,and then'backwardly through the flu'e 26. f After traversing the dues as products ofcombustionnd an described, theoutlet through the rear exit llue 30 if its damper be left open, these circa mstances.
