BAKING-ovEN.

Specicaton of Letters Patent. Patented May 13, 1919.

Application filed July 9, 1918. Serial No. 244,087.

To aZZ 'whom t may concern:

Be it known that I, MILTON FEDER, citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Bakin -Ovens, ofi

ywhich the following is a speci cation.

'Ihe invention relates to an improved baking oven, and has for its object to provide an oven of simple construction which will be more efficient in operation and produce better results in baking than ovens heretofore made.

'Ihe invention is illustrated in the accompanyingdrawings which form a part of this specification and the appended claims.

Referring to the drawings:

Figure 1 is a front elevation of the oven with the oven casing swung partly open.

Fig. 2 is an end elevation of the oven.

Fig. 3 is a cross sectional view of one of the reel bearings.

Fig. 4 is a cross section of the oven taken in a plane corresponding to the line 4-4 of Fig. 1, but showing the upper casing` close y In the drawing, 1 indicates' a frame formed with two legs 2 which rest upon the Hoor and support the oven. The oven includes a closure 3 which is preferably cylindrical in form and 'mounted horizontally on said frame. The closure is made with a lower semi-cylindrical section" 4 which is fixed on frame 1 and an upper semi-cylindrical section 5 pivoted in the rear at 6 to said lower section, the line of separation of said sections being substantially coincident with the horizontal diameter of the closure.A

section at 8 to swing down into its open position. Latches'9 are provided for holding the door 7 closed. A handle 10 is secured to the door 7 for lifting the forward part of the section 5 and swinging it upward and backward on pivot 6, and for opening the door. Stays 11 are pivoted at their upper ends to the ends of the section 5 at 12 and are provided with notches 13 to receive pins 14 in the ends of the section 4 whereby the section 5 is held in partly open position. On a shaft 15 extending centrally and horizontally of the closure 3 and journaled in anti-friction roller bearings 16 on the frame 1, is secured a circuitous series of means for supporting articles to be baked, preferably in the form of a reel 17. Shelves 18 are pivotally suspended on the reel 17 longitudinally of the reel to receive the baking pans 19, and to swing and suspend vertically on their pivots as the reel is ro,- tated. The section 4 is provided with a longitudinal slot 20 in the bottom thereof directly under which is located a burner 21 mounted onthe frame 1. A gear 22 is slidably keyed on shaft 15 to mesh with va pinion 23 journaled on the frame 1 which also meshes with a gear 24 journaled on the frame. A shaft 25 is journaled in bearings 26 on the frame 1, on which shaft is secured a worm 27 which meshes with the gear 24. A pulley 28 is secured on the end of shaft 25 over which extends a belt 29, which belt also extends over pulley 30 of a motorY 31.

Normally 'the reel 17 is' rotated by the motor 3l through the medium of pulley 30, belt 29, pulley 28, shaft 25, worm 27, gear 24, pinion 23 and sections are partially separated by the stays 11, the reel still enters the upper concave section, and if traversing of the reel be continued at such time the cooling of the bake may be more gradual'if desired.

A glass window 40 is provided in the front of the oven closure through which the baker may observe the bread in the baking pans 19. Bread is very easily burned in gear 22. The reel however may be disconnected from the motor other ovens by the heat remaining in the I ovens after the heat is turned oif, no means being provided for discharging the remaining heat in the oven. My oven however may be opened wide by swinging open the closure section 5 so that the remalning heat in the ovenl will readily escape and avoid burning the' bread.

The roller bearings prevent vibration of the reel and falling of the bread, which takes place in other ovens when the oil is dried out in the bearings by the heat,

. of the oven in the lower part thereof andi Batlle plates 50 extendfrom end to end vertically through'the slot 20, providing gas outlet passages 51 between the plates and the wall of the,J 4oven and the sides of sald slot.

Having described my invention, I claim as y new and desire to secure by Letters Patent:

1. A bakery oven including an oven closure having a lower section' and an upper section, the latter being pivotally connected to the former whereby the closure may be opened, and said oven having a circuitous series of means for supporting articles to be baked, extending into both sections of the oven closure.

2. A bakery oven including an oven elosure having a lower section and an upper section, the latter being pivotally connected to the former whereby the closure may be opened, and a reel rotatively mounted in the lower section for receiving material to be from the walls thereof, and means for supplying heat to said closure at the bottom thereof.

il. A baking oven comprising a closure divided horizontally into upper and lower sections, having a circuitous series of traveling baking supports mounted in said closure and having means for traversing them therein; said sections being vertically separable to develop a pair of opposed concaves with a laterally presented cooling opening between them and the path of the traveling baking supports extending into the cavities of the sections when the latter are so separated.

5. A baking oven comprising a closure divided horizontally into upper and lower sections and a circuitous series of traveling baking supports mounted in said closule and having means for traversing them therein; said sections being hinged together along one side to render themY vertically separable by swinging movement. to develop a pair ot opposed concaves with a laterally presented graduated cooling opening between them; the path of the traveling baking supports extending into the cavities of both sections when the latter are soiseparated.

6. A baking oven comprising ya closure divided horizontally into upper and lower sections and having a circuitous series of traveling baking supports mounted therein with means for traversing the same; said sections being hinged together along o'ne side to render them vertically separable by swing- Aing movement and having means for defining a limited separation of their three sides and thereby developing a pair of opposed concaves with a laterally presented graduated cooling opening between them; the path of the traveling baking supports extending into and the traversing means being adapted to cause them to move through the cavities of both sections when the latter are so separated.

7. A baking oven comprising a closure divided horizontally into upper and lower sections, having a eircuitous series ot traveling baking supports mounted in said closure and having means for traversing them therein; said sections being vertically separable to develop a pair of opposed conca'vcs with laterally presented cooling openingbetween them the path of the traveling baking snpports extending into the cavities of the scctions when the latter are so separated and the free wall of one of the sections being provided with a door to increase the opening into the space between the sections.

8. A baking oven comprising a closure divided horizontally into upper and lower sections, having a circuitous series of traveling baking supports mounted in said closure and having means for traversing them therein; said sections being vertically separable to develop a pair of opposed concaves with laterally presented cooling opening between them; the path of the traveling baking supports extending into the cavities ot the sections when the latter are so separated and the free wall of one of the sections 4being provided with a door to increase the opening into the space between the, sectionsl and affording means through which to manipulate the section which carries it in developing vertical separation between the sections.

9. A bakery oven comprising a cylindrical closure mounted with its axis horizontal and divided diametrically into upper and lower sections hinged together along one side of the cylindrical wall and leaving free separable edges on the other side thereof; a circuitous series ot' traveling supports for articles to be baked having their path of travel extending through both sections: the upper section having a door hinged near its free upwardly swingingedge and swinging outwardly from said sections.

ln testimony whereof l alix my signature.

MILTON FEDER.
