specification.

My invention relates to bakers installations, and particularly to an installation cmployin ovens of the general type illustrated 1n my atentNo. 1,135,172, pril 13, 1915.

yThe object of my invention is to improve the lay-out and operation of the plant.

In the accompanying drawings- F ig. 1 is a more or less diagrammatic plan of a layout for a four-oven plant;

Fig. 2 is an enlarged side elevation of portion of the plant;

Fig. 3 is a plan of a modified lay-out; and

Fig. el is a vertical section on an enlarged scale on the line 1r-4c, Fig. 3.

ln installations or the type employing ovens and racks of the type shown in my atent above mentioned, it has heretofore heen customary to mount the racks on wheels so that they may be readily shifted from place to place about the bake shop. lt not infrequently happens, especially in large bake shops, that the racks are not` only shifted from place to place over various courses, but when not in use, are left standing idle in various positions, where they obstruct the operations of the shop. By the present invention the installation 1s such that the course of the racks is limited to certain dened lines of travel, which may be varied with the needs of any particular shop layout, but in any event prevent the promiscous clogging of the shop area with racks temporarily not in use. Furthermore, the construction is such that the travel ot the racks is such that they are presented in exact position, not only with respect to the ovens, but also to the proofing rooms. 'lime heretofore lost in adjusting position is thus saved. lt

is a further object of nay-invention to support the racks from over-head rails, thus maintaining the floor uninterrupted and smooth, so that it may be readily kept clean and sanitary. C

In the lay-out o Fig. l l have Iindicated a battery of four ovens 10, 11, 12 and 13, and a corresponding battery o' four proofing chambers 14, 15, 16 and 17. .arranged paralle to the oven battery, but spaced suciently therefrom to permit the manipulation of the racks in the manner hereinafter set forth.

The present plant isdesigned primarily for bread baking. A. moldin machine 18 is 60 therefore provided, while adJacent it l have indicated a loading table 19, which is preferably of one of the types shown in my a plication of-even date herewith. The ra'c `20, vinstead of being supported on running 85 wheels, as has heretofore been the practice,v are suspended by trolleys 21 from over-head tracks 22. The trolleys and tracks may be of any suitable system, although l refer the Londen over-head carrying systemEby reason 70 of its simplicity and efficiency for the present purpose.

ln the lay-out indicated, the loading table 19 is located in one corner ofthe work room. lhe track 22 leads therefrom around4 the 75 curve 23 to the end line 24, from which are branched by switches 25 the three lines 26, 2'4" and'28 parallel to the continuation 29 of the end line .24, and at', right angles to the latter.V The parallel lines 26 to 29 inclue0 sive are arranged to pass directl through the proofing chambers 14 to 17, and7 thence 1n the same direct line to dead ends at the ovens 10 to 13. A return line 30 at right angles' to the-dead ended lines 26 to 29 is connected e5 to the latter by the switches 31, 32, 33 and 34. The return line 30, assing` between the proofing chambers an ovens, is connected by the curve 35 to the track reach 22 leading to the loading table. An unloading table 9o 36 is arranged in advance of ythe loading table and receives the discharge from the racks as' they return to the loading table from the ovens. V v The operation of the plant .is readily uno5 derstood. Assuming a rack. to have been loaded at the table 19, it is shoved around the curve 23 onto the end line 24, thence to one vor the other of the parallel lines 26 to 29, which pass through the proong cham- 4'loo bers. The rack is halted in vthe proong chamber sutiiciently long to prove the goods carried by the rack, and is then advanced from the proofing room along the same line to dead-end position in front of theoven. 105 lf the oven 'at the dead end of any line is already charged, the rack of proofed goods on that line ma be shifted y one of the switches 31 to t e return end line 30, and' shunted across the latter to the switch lead- 110 tables or other devices for v the oven.

ing to an empty oven, into which the shelves from the rack are shoved in well understood manner. A fter the goods have been baked and the shelves are drawn out upon a rack, the rack is shifted by one of the switches 31 to 34 to the'return end line 30 and moved along the latter to the unloading table 36, where the baked goods are discharged and the rack advanced to the loading table again for a return of the circuit.

It will be noted that `the arrangement of the track system is such that while the lines are dead ended in front of the ovens 10 to 13, the racks are returned to the line 30 with their front ends faced in the direction of travel, thus obviating the'necessity for turn rectifying their position.

In Fig. 2 I have illustrated on a larger -scale an arrangement of the dead-ended lines 26-29 for facilitating lthe charging of As here shown the terminal section 37 of the dead-ended line ishinged at 38. Its free end may be lowered by any.

suitable means, such as a cable 39 to incline ,the rack downwardly, `so that the baking shelves 40 may be readily run off the rack onto the' oven tracks 41 with which the tracks 42 on the rack are brought into register A stop 43 for the track section 37 determines the position of the rack. Brackets 44 may also be provided on the oven to cooperate with the extended ends of the rails 42 of the rack for the same purpose, as, well as to guide the wheels of the oven shelves from the rack to the oven rails. As will be noted,

the forward ends of the lower tracks on the rack are extended a greater distance than those at the top of the rack to compensate the greater spacing of the bottom of the rack from the oven in inclined position. The same effect may be attained by varying the projection of the guide racks 44 on the oven ont.

A modified lay-out is illustrated in Fig. 3. Passing fromthe loader 45, which may be vof one of the types shown in my application ofl even date. the racks enter an vLshaped tunnel proofing chamber 46, through which they are advanced by an endless chain con- Vveyor 47 having pawls 48 (Fig. 4) which engage studs 49 associated with the trolley 50. he track 51 passes through the proofing chamber and delivers the racks to the end line 52, from which the dead-ended' lines 53 are branched by switches 54 and lead to the battery of ovens 55. The racks are again returned to the end line 52, across the switches 54, and are then shifted inthe direction of the arrow to the unloading table 56, and thence againto the loader 45. In an arrangement such as this, the v,central floor 'space of the chamber is kept free from obstruction at all times. The endless conveyor 47 for advancing the racks through inseam' the roofing chamber is preferably intermittent y operated by a motor 57 controlled by manually operated switches 58 and 59 at opposite ends of the proofing tunnel.

Various other lay-'outs will readily occur to those dealing with the problem without, however, departing from what I claim as my invention.

I claim-` 1. In a bakers installation, a battery of ovens, each adapted to receive a series of removable, superposed, baking shelves, proofing chamber means, a loading table, an unloading table, racks adapted to support in superposedposition a group of baking shelves foi-.an oven, trolley 'means for overhead suspension of the racks, and an overhead track system for the rack trolleys, said track system comprising a circuit of the loading table, proofing chamber means, ovens, unloading table, and thence to the starting point.
