To all-whom t may concern: Be it known that I, FRIEDRICH Anschr- BACH, a citizen of the. Republic of'Switzerland, .residing at Aarau, Switzerland; have invented certain new and useful Improvements in Dough-Dividing Machines; and I do hereby declare the following to bei a; full, clear1 and exact description of the invention, such as will enable others skilled" in the'art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to tan improved construction of a dough-dividing machine having a rotarycylinder provided witlra number Vof pockets in its circumference.

The Vmachine according to this invention is provided with a movable body and a rotary cylinder comprising a plurality of Separating walls which do not change theirposition relatively to the cylinder. while the ma; chine is running. These separating walls control the movement of said movable body adapted to act as a closing member for the pockets of the cylinder, so that the single pockets are closed by said body upon their iilling with dough and are again opened later, on owing to the action of the separating walls upon said movable .body-jin order that they may discharge their contents. This invention will .now be more particularly described with reference to theaccompanying drawings, which illustrate a constructional'example of the invention'.

In these drawings: Figure 1 is a longitudinalsection of the improved dough-dividing" machine,

Fig. 2 is. a corresponding. front' view, Fig. 3 shows a part of Fig. 1 on an enlarged scale, f

Fig.` 4: is a longitudinal section 'on an en-A larged scale of the .cylinder provided* with a number `of pockets 1n its circumference,

In the drawings, l denotesapairfRill" leysmountedon a shaft1`2.'v OnY this shal i's' also mounted a sprocket j, w he el' danseurs its motioned@ sprocket wheels.,

by means of a chain 4:. The sprocket wheel 5 transmits then its motion to a sprocket wheel 7 arranged above sprocket wheel 5 by means ofv a chain 6. Sprocket wheel 7 vis Xed to. a shaft 44 carrying also a toothed wheel 8 engaging with a toothed wheel 9 which is adapted to rotate the cylinder 12 provided with a number of pockets in its circumference. To this end I provide the toothed wheel 9 with a rim 10 (Fig. 4) to which I :[iX a ring 11 rigidly connected to one end of the cylinder 12. To a similar ring 13 .on the other end of cylinder 12 is fixed a cover 14. The cylinder 12 has radial slots. 15in each of which is disposed a movable .separating wall 16. These radial separating walls arel provided at .each end with a gudgeon 17q which engage loosely in spiral grooves 18 of disks 19. The latter are loose on the hubs 20 of cylinder 12. This cylinder ha'sbetween said radial separating walls recesses. 21 forming together with the separating walls 16 trough-like pockets. Holes 22 connect the bottom of these pockets with air-passages 23 in the cylinder 12. The disks 19 carry toothed wheels 2limeshing with teeth 25 provided on the circumference of sleeves 26, which surround the hubs 20 and rest on sho-ulders of these hubs. A shaft 27 passes as well through both sleeves 26 as thel hubs 2O and the central'portion of the cylinder 12. To one end of this shaft 2'( is fixed a collar 2.8 provided with aprojection 29-,which is adapted to receive a hand-crank 3,0, Vwhile the other end of this shaft has. a screw-thread *31, so that a press lever 32pmvijdedwith a screw-threaded hole may be secured to it. The toothedl wheels2f1 engage also on one side of the cylinder 12 with "an internal gear v33 .of the rim 10 and on the other side with an internal gear 34- ofthe cover 14.

' On the shaft 2 are also pivotally mounted. twol'evers 35 carrying a drum 36 loosely mounted in these levers. As shown in'Fig. 1, .this dru'in 3 6 is adapted'to act as .a closing member for the pockets of the rotary cylinder 1 2. To a connecting rod of these levers 35 is. fl-'xed one end of a cord. 37 'carryingl at th' 'other-jeudis. weight 38.

Rail 46 is also provided with a longitudinal slot' 50' engaging with shaft 119. The trough 45 con'tainsa cylindrical cleaning and spraying brush 51 and a flour-feeding roller 52. The brush 51 as well as the roller 52 are driven in all positionsof the trough l5 by a train of toothed wheels 53 operatively connected to shaft L14. 54 denotes a perforated iron-sheet, which rests partly on' the brush-roller 52.

Shaft 2 carries also a roller 55, over which isfed a oonveyer-belt 56, which runs on the other end over an adjustable roller 57.

The operation oithis dough-dividing machine may tor instance be asiel-lows:

The dough falls r from the hopper .58v

through the aperture 63 into the pockets of the rotary cylinder 12. 'Thereby7 slide 59 serves to regulate the douglrquantity 'passing through said aperture V63. Upon a rotation of cylinder 12 a radial separating wall 16 pushes the drum 36 backward, that is away from this cylinder 12, againstgthe action el weight-BS, the .latter causing said drum 36 to move shortly afterward again toward Vthe .cylinder 1'2, soV that a illed pocket is now Closed in the manner shown in Fig. 1. The amplitude of movement of thel .drum 3 6 during the dough molding operation `is equal to the sumj ofthe middle' ordinates .ofthe aros ot the -cylinder ,and of the -drumincluded between the points of intersectionpol` a .pair of walls lwith the surfaoe ofthe drum. y'The lower one of the pair of walls vcoming into operation is in contact with the drum until the mold chamber is completely filled, whereupon the 'up-V pervvall byl its ldownward rotation .finoves thedru-mpitsfull amplitude until the point of. contact of said wall with the drum passes a linejoiningv the rcenters of vdrumla'nd cylinder. The drum 'thereafter remains in cointact with. ysaid ywall while moving into the spacebetweenthis walland the next fol lowing. walluntil it contacts with the latter,

whereupon the operationv isV repeated. Thus,

terminate .momentthe earn-disk 48 causes the brusha'oller 51 to swing into a pocket 'of the-cylinder 12, as shown in Fig. 3, so

that this pocket is cleaned and strewed with ll'iou'r, as' the brush 52 sprays flour through the sieve 54, which falls then on the bottom arranged beneath brush 51. This flour is then conveyed by the brush 51 into the cleaned pocket. Theflour-strewing

device

39, 40 basato pro-vide for an easy disconnectin of thefdrum 36 from the dough contained in the pockets. As already stated, the drum 36 -is loose in the arms 35, its rotation being brought about by the separatin 'walls 16.

iile the machine is running the press lever 32 is tightened, so that vthe sleeves 26 connected with the shaft 27 are pressed tightly against the hubs 20 of the cylinder 12. Thus, the toothings 25 of this cylinder prevent an individual rotation of wheels 24. Should it be desired to Vadjust the separating walls 16 in a radial direction l move the lever 32 in such va manner, that it ceases to press on said sleeves 26. When this is the case,=1 may rotate the sleeves 26 by if'.-

means of the crank 3 O`without the cylinder 12 being moved, so that the disks 19 are rotated.- The latter effect thereby a radial adjustment of all separating walls 16, as the ,gudgeons 17 provided on these walls engage with the spiral grooves 1S of said disks 19. As soon as the walls have been adjusted in the required manner, press lever 32 is again tightened, so that any further displacement of. said walls 16 is prevented. According as these walls have been adiusted in the one or other ldirection the divided dough-pieces .are rgreater or smaller .and the feed vvto thevpockets has therefore to be aecordingly varied. .This may be etl'eoted by moving hand-wheel 62, the slide 59 being thereby adjusted and the size ot .the .aperture 63 varied.
