421,389. Cutting-machines for waffles &c. GOHRING & HEBENSTREIT MASCHINENFABRIK BETRIEBS-AKT.-GES., 62, Stosch Sarrassanistrasse, Radebeul, Dresden, Germany. July 24, 1934, No. 21663. Convention date, June 16. [Class 31 (i)] In a cutting-machine for waffles &c., of the type having two cutting tables with sliding carriages adapted to move at right-angles to each other, each carriage having a thrust bar coacting with a cutting frame, a control gear is provided for the movement of the carriages, the gear comprising two clutches one effecting the reversal of movement of driving shafts for the carriages, and the other determining which of the shafts is to be rotated. In the construction shown, the machine is driven through a pulley 1 which, through pinions 2, 3, drives a bevel wheel 4 meshing with bevel wheels 5, 6. These wheels are loosely mounted on a shaft 8 to which they may be coupled by a clutch 7. The shaft 8 carries a spur wheel 9 adapted through a gear wheel 10 to actuate a wheel 11 keyed on a shaft 12. The shaft transmits the drive to a clutch 13 by means of which a bevel wheel 14 or a coupling 18 is rotated. The wheel 14 meshes with a bevel wheel 15 carried by a shaft 16 which is provided with a pinion 17 for actuating a carriage having a thrust-bar 22. The coupling 18 is adapted to rotate a hollow shaft 19 carrying a pinion 20 which serves to actuate the carriage having the thrust-bar 21. The pinions 17, 20 gear with racks provided on the thrust-bars 22, 21 respectively, For controlling the machine, a lever 27 is provided capable of taking up three positions. Assuming that the clutch 7 is engaging the bevel wheel 5, and that the lever 27 is moved from the central position d to the position c, the clutch 13 engages with the member 18 so that the pinion 20 is driven to operate the thrust bar 21. The bar moves towards the cutting frame until it engages a stop 23, effecting thereby the movement of a lever 28, link 29, and lever 30. The lever 30 is mounted on a shaft 31 which carries a clutch lever 32, so that the clutch 7 is disengaged from the pinion 5 and engaged with the pinion 6. The direction of movement of the thrust bar 21 is thereby reversed, its return movement being checked when a striker 33 thereon engages a stop 5, whereby through a lever 34 and link 35 the hand-lever 27 is brought to its central position and the clutch 13 is disengaged from the member 18. Movement of the lever 27 into the position e similarly causes the thrust bar 22 to make one reciprocation to and from its cutting frame. To prevent the hand of the operator from being jammed between the thrust bar 21 and the cutting frame, guard bars 440 are provided which are pivotally mounted and adapted to be moved by a lever 44 from a guarding position, shown in dotted lines, Fig. 3, to an ineffective position shown in full lines. Before the hand-lever 27 can be moved from the neutral position d to the position e, the striker 33 must be moved out of the way of the stop 25, and this is effected by giving one complete oscillation to the guard lever 44. The lever is provided with a projection 45 adapted when the lever is moved in an anti-clockwise direction to raise a member 47 connected to the striker 33. The striker is thus raised until it passes a bar 49, whereupon a spring-pressed movable pawl 48 on the striker engages the top of the bar, retaining the striker in the raised position out of the way of the stop 25. When the thrust bar 21 has moved away from the bar 49, the striker 33 is returned to its normal position by a spring 51. A similar safety device is provided for the thrust bar 22.
