Abstract: 10,713. Callow, J., and Callow, H. L. May 5. [Cognate Application 28,396/09.] Dough dividing and working machines; rolling- machines.-Comprises a macbine for converting dough from a sheet into loaf form, in which portions of dough are alternately sheeted by means of rollers &c. and folded by means of mechanicallyoperated pivoted-flap devices. Portions of dough are placed upon a conveyer 4, Figs. 2 and 4, and timed by means of a movable fence, being then fed beneath sheeting-rolls 10, deposited upon folders 13, 14, and, after folding, deposited upon a second conveyer 17, flattened by a roller 22, and deposited upon a second series of folders 24, 25, acting at right angles to the first pair, flattened by a roller 29, then carried to other folders if necessary, and finally fed to a conveyer 28 which deposits them on to a pair of final folding-tools 30, 31, from which they pass to a delivery conveyer. The conveyers 4, 17 are driven intermittently and are passed round pairs of rollers 5, 6, 20, 21, carried by a reciprocating frame so that the dough portions are first advanced over the folding - tools and then deposited thereon during the return movement of the frame. The flap 14 is operated by means of a claw 97, Fig. 5, carried by the reciprocating frame engaging with a tooth 98, and is elevated to clear the folded dough portion by means of an arm 101 carrying a roller 102, which is engaged by a notch 103 in the reciprocating frame 7. The flap 13 is operated by means of a slot 111, Fig. 8, in the frame 7 acting upon a pin 112 and causing a pinion 104, secured to the flap, to move over a fixed segment 105. Motion is imparted to the flaps 24, 25, from the reciprocating frame through spur and bevel gearing, which is so arranged that the flap 25 operates first. The final folders 30, 31, Fig. 12, are carried by the reciprocating frame, and are operated by the weight of the dough portion, which tilts the folders as shown in dotted lines; after the delivery of the dough portion, the folders are restored by suitable gearing. Instead of providing the conveyers 4, 17, with reciprocating portions to feed the dough to the folders, these may be reciprocated ; or the dough may be transferred to the folders by a pivoted framework of parallel tapes or bars or pneumatic devices. The dough may be treated by the same flattening and folding devices instead of a series, the conveyer 4 in this case delivering the dough slab on to a tray which is turned through a right-angle after each flattening operation. The sheeting-rolls 10, Fig. 3<a>, are normally raised by blocks 90 mounted upon the reciprocating frame, so that, during the forward movement of the frame, they roll down on to gauge tracks 91 and form the dough into sheets ; during the return movement of the frame, the tracks 91. are withdrawn laterally, allowing the rollers to pass on to lower tracks 94, and further roll the dough. In place of the rolls 10, the dough may be sheeted by means of rolls mounted in a hanging frame operated by cams or screws. Fig. 14 shows another sheeting - device comprising converging bands 4, 66.
