Abstract: 115,976. Kuhtz, F. Aug. 2, 1917. Proving or raising appliances.-Apparatus for proving dough, wherein the dough pieces are passed from the dividing-apparatus to holders which carry them through the fermenting- apparatus, are arranged so that the two devices move in fixed relationship with one another, the dividing-apparatus actuating mechanism which enables an external power source to operate the fermenting-devices. The dough masses are carried from the dividing-machine over a roller to a carrier band 2, Figs. 2 and 7, passing over pulleys 6, 8, 10, 11, 12, the supporting-frame being pivoted at 16 and being telescopically adjustable in length by means of the sliding rod 14 and guide 13. The dough is delivered into rows of holders 3 carried by frames 4 supported from chains 5 passing over chain-wheels 60. The roller 6 is driven by a pulley 7. The band is moved so as to deliver the dough to any one of the series of holders arranged in a row. A shaft 44, Figs. 3 and 5, is rotated from the dividing- machine once for each delivery of a piece of dough. On it is a sliding sleeve 46 forced in one direction by a spring 47, and on the other at each rotation of the shaft by inter-engaging teeth 49, 50 on the sleeve and on a fixed bearing 45 respectively. At each movement against the spring, a nose 48 engages a roller 43 on a lever 42 and forces it, against the action of a spring 75, so that a projection 53 at its other end is raised from a slot 52 in a disk 51, which is fixed on a shaft 20, and travels on its periphery during one rotation of the shaft. During the same time, a connexion of the lever 40 to a coupling 33, Fig. 2, loose on the shaft 20, causes the coupling to engage one element of the reversing-gear 34, 35, 36, whereby the shaft is driven by the spur-wheels 31, 32 (the latter forming part of the loose coupling 33) from a constantly-running power shaft 30. The shaft 20 is driven alternately in opposite directions, according as a loose intermediate sliding sleeve 39, with couplings 37, 38, is actuated. On the shaft 20 is a sliding bevel-wheel 24 engaging a bevel-wheel 25 on a shaft 26 carried by a slide 18. which can travel backwards and forwards on the shafts 20, 21. On the shaft 26 is a spur-wheel 28 which engages a fixed rack 29, so that as the shaft 26 is rotated, the slide and the free end of the carrier band supported thereon are moved backwards and forwards. When the slide reaches one of the adjustable stops 76, it pushes the sliding shaft 21 to the right or left, and then, by means of the lever connexions 54, 57<1>, 59, 58, 56, the sliding sleeve 39 is actuated to cause the couplings 37, 38 to reverse the direction of rotation of the shaft 20. When the projection 53 snaps back into the slot 52, the coupling 33 is moved away from the reversing-gear by means of the spring 75, and the rotation of the shaft 20 therefore stops, while the slide 18 has been moved towards the right or left a distance equivalent to the distance from one holder 3 to the next. An extension 70 of the lever 57<1> acts upon another lever 68, whereby the latter, at a pre-arranged time, causes couplings 64, 65 to engage and actuate a gear-wheel 63, loose on the shaft 30, which drives another wheel 62 on the driving-shaft 61 of the holders 3. To enable the apparatus to continue to move so as to discharge the dough after the dividing-machine has stopped. a lever 79 is connected to the lever 40, by which the coupling 33 may be put into engagement by hand and secured therein by a pin 80 engaging a hole 81 in the frame 23 of the machine.
