Application filed January 27, 1905. Serial No. 242,946.

To all ivf/tomy 'it muy concern:

Be it known that I, Simms-Y Jacoesorv, a

citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented a new and useful Continuous EakingOven, of which the following is a specification.

My invention relates lto ovens through which the material to be baked is continually moving, and the objects of my improvements are, first, to provide heating flues below and above the baking chamber and means for forming communication between the baking chamber and a lire place; second, to arrange the fines so that the heat in the different parts of the baking chamber can be regulated; third, to have the material carrier travel in and out of the baking chamber in a horizontal plane; fourth, to secure the pans, upon which the material to be baked is placed, to an endless chain in such manner as to facilitate their travel through the baking chainber, and other objects to become apparent from the description to follow.

Different classes of bakery goods require to be baked different lengths of time, and to accomplish this properly the heat in the baking chamber must be regulated quite accurately. s

T iis invention provides for the regulation of heat in all parts of the baking chamber and insures proper baking.

i have illustrated my invention on the accompanying four sheets of drawings forming a part of this specification, in which Figurc 1 is a side elevation foreshortened of an oven embodying my invention; Fig. 2. is a longitudinal section through the same; Fig. 3, is a cross section on 3 3 of Fig. 1; Fig. et, is a cross section on i-il of Fig. 1; Fig. 5, is a plan section on of Fig. Q; Fig. 6, is a plan section on GWG of Fig. 2; Fig. T, is a plan section on 7 7 of Fig. 2; Fig. 7a, is an enlarged perspective view showing the manner ot attaching the pans to the chain; Fig. 8 is a side elevation foreshortened showing a modified form of my invention; Fig. 9, is a vertical longitudinal section through the same; Fig. 1G, is a cross section on 10 10 of Fig. Fig. 11, is a cross section on 11-11 of Fig. 9, Fig. 12, is a plan section on 12u12 of Fig. 8; Fig. 13, is a plan section on 13 13 of Fig. S; and Fig. 14, is a plan section on 14-14 of Fig. 8.

Similar reference characters refer to similar parts throughout the several views.

The complete structure is built of brick or any suitable material preferably faced with tile or lire brick wherever exposed to eX* treme heat.

I will first describe the preferred construction illustrated in Figs. 1 to 7. rEhe baking chamber 15 is in the form of two iiues open to the exterior at the front side of the structure and connected by the short flue 1G in the rear end of the structure. T he tlues 15 are separated by the center wall 17. The structure in so far as the heat lines below and above the baking chamber 15 are concerned may be considered as front and rear halves which are arranged alike. Below the baking chamber 15 close to either end of the structure is a lire place 1S provided with the ordinary grate 19. Extending from the lire places 1S toward the center of the structure and immediately below the baking chamber 15 are the four tlues 2O which communicate with the tlues Q1 near the center of the structure; the fines 21 extend upward in the walls beside the baking chamber 15 and communicate with the tlucs 22' which are located immediately above the baking chamber 15. The tlues 22 extend from a point near the center of the structure toward either end near which they communicate, by means of the tlues 23, with the chimney l'iue 2e. rlhe dampers 25 are provided in the four flues Q3 for regulating the iow of hot gases therethrough. The hot gases formed by combustion of fuel in the lire places 1S will pass through the tiues and heat the bottom of the baking chamber 15, thence they will pass upward through the ues 21 into and through the iiues 22 and heat the top of the baking chamber 15, after which they will pass out through the tlues 23.

To assist in heating the baking chamber 15 and to be able to conduct some hot fumes or gases directly, into the baking chamber 15, a central tire place 2G is provided below the baking chamber 15. One flue 27 leads from the lire place 2G forward to a vertical hue 2S which communicates with the chim ney flue 2st; and one tine 29 formed in the wall 17 leads from the tire place 2G toward the rear into the baking chamber 15. The flue QS is provided with a damper BO, and the. flue QS) is provided with a damper 31. Yilhen the damper SO is open and the damper 31 is closed the gases from the Vtire place 2G will l;

pass out through the chimney flue 24, and when the damper 31 is open and the damper 30 is closed the gases from the Hre place 26 will pass int-o the baking chamber 15. To permit any surplus gases or heat to escape from the baking chamber, the Hue 32 is provided in one of the walls forming communication between the oven 15 and one of the Hues 22; and said Hue 32 is provided with a damper 33.

The material to be baked is fed into one of the baking chamber Hues 15 and out of the other by an endless chain carrier, which consists of the endless chain 34 passing over the sprocket wheels 35 and 36, and having the plurality of pans 37 attached to the chain 34 to travel therewith. The wheel 35 is located centrally in the rear end of the baking chamber about equidistant from the three outer walls and is secured to the vertical shaft 3S journaled at the top and bottom ends and having a gear 39 secured thereto which is preferably driven by a worm 40. The wheel 36 is located some distance in front of the structure centrally of the two baking chamber Hues 15 and is secured to the vertical shaft 41 which is journaled at its upper and lower ends in the adjustable bearing blocks 42. The chain 34 travels in a horizontal plane and the pans 37 are preferably detachably secured to the chain 34 to travel in a horizontal plane. One edge of each pan is supported by the chain 34 and the remaining edge is supported by and slides upon an endless rail 43 arranged in a loop extending in the Hues 15 and-16 and encircling the wheels 35 and 36. The pans 37 may be made of sheet metal either perforated or not or of wire and secured to the chain in any desirable manner. I have shown them secured to the chain in Fig. 6, by two pins 44 provided on each pan which extend down into perforations provided therefor in the strap 45 which is rigidly secured to a link of the chain 34. To assist in supporting the pans 37 a plurality of metal straps are provided under each pan secured to the links of the chain 34, and the ends of some of the straps remote from the chain extend beyond the rail 43 so as to slide on said rail when the chain is in motion. Since the strain caused by the chain while pulling the pans around the circuit through the baking chamber is on the forward strap 45 and the chain is Hexible the pans tend to twist so as to bring their edges out of alinement with the line of travel and thus contact with the walls of the oven. To retain the pans in perfect alinement and avoid any possible damage a stop 46 is provided above the chain 34 near the rear edge of each pan, which may be formed by bending up the end of one of the supporting straps.

In operation lires are constantly kept up in the fire places 18 and 26, the dampers are regulated as desired and power is applied to rotate the worm 40 thus causing the chain same and all material resting on the pans will be pushed from the same as the pans travel under the ejector.

In Figs. 3, to 14, is shown a modified construction of my invention, which has the baking chamber Hues l5 and 16, chain 34, wheels 35 and 36 and their connections, pans 37, ejector 49 and rail 43 all arranged as described in connection with Figs. 1 to 7. The pans 37 are secured to the chain 34 by two pins 50 extending up from the chain and through perforations provided therefor in the pan. The pins 50 extending through each pan, are placed such a distance apart that they will serve to retain each pan in its proper position relative to the line of travel. One of the perforations in each pan 37 is elongated so that the pin 50 can freely move therein to compensate for the travel of the pans over the wheels 35 and 36. The fire places 51, 52 and 53 are provided to heat the baking chamber. The lire place 51 is located in the front end of the structure and communicates with the Hue 54 above the baking chamber Hues 15 by means of the vertical Hue 55 provided in the side wall of the structure. The Hre place 52 is adjacent the fire place 51 in the front end of the structure, and communicates with the Hues 56 arranged below the baking chamber 15. The end of the Hue 54 remote from theHue 55 communicates with the chimney Hue 57 by means of the short vertical Hue 5S which is provided with the damper 59. The ends of the Hues 56 remote from the fire place 52 communicate with the chimney Hue 60 by means of the vertical Hues 61 in either side walls of the structure which are provided with the dampers 62. Two Hues lead from the fire place the one 63 leading to the interior of the baking chamber 15 and the other 64 leading to the chimney Hue 57. The damper 65 is provided in the lHue 63, and theA damper 66 is provided in the Hue 64. The chain 34 is caused to travel through the baking chamber 15 in the direction indicated in Fig. 13, by passing over the sprocket wheels 35 and 36 and has attached thereto t-he pans 37. The sprockets 35 and 36 have the same connections as previously described in connection with the construction shown in Figs. 1 to 7. The pans 37 however are secured to fl O the chain 3% by being provided with two perforations through which the pins extend as previously referred to.

49 I may prefer to place a stationary brush or it may be a revolving brnsh conveniently driven by the shaft ell. 1n place ot the ejector shown and described there may be some means provided tor tilting the pans up on one side after leaving the baking chamber and thus dumping the baked material cti' of the same.

1 desire to be understood as limiting myseit to the exact interpretation ot the appended claims only so far as is necessary when considering the prior state ot' the art to which this invention pertains.
