Title: Apparatus for transporting and stacking moulded bricks
Inventor: GUNZELMANN RUDOLF
IPC: B65G57/26
Filed: 1961-05-11
Abstract: 983,153. Stacking bricks. ATLAS-WERKE A.G. May 11, 1961, No. 17319/61. Heading B8C. In a fully automatic machine for moulding and stacking bricks, the mouldings 16 from a reciprocating table press 10 are taken to a stacking device by an intermittently moving conveyer 11 and by means of a gripper arrangement 19 are transferred to a truck 18 which when loaded proceeds to a hardening tank. The stacking device is set in motion by the arrival of a brick at a mechanical or optical detector 20. The grippers, as described in Specification 881,496, descend, grip, rise and then carriage 54 moves to a position over the truck 18 dependent on the setting of a rotatable cam drum 21 which operates rollers 68a of switches 64, 65 on the carriage, Fig. 2A. The drum is rotated stepwise by a cam 74 attached to the carriage acting on a ratchet-andlever device 72, 73 which co-operates with a gear-wheel 71 on axle 21a. Descent of the grippers over the truck allows deposition of the bricks on to the truck platform or a part-formed stack. Downward movement of the grippers is halted by means as described in Specification 881,496, which may be supplemented by a series of buffers 148 and cushions 149 (Fig. 3B, not shown) or by a more sensitive means, as described in Specification 881,497, which involves feelers 78, 79 (Fig. 8, not shown) and a braking device 117 connected to rods 43, 44 (Fig. 6, not shown). In this arrangement the grippers are halted before contacting the truck platform or bricks thereon. The carriage is halted over the conveyer belt on its return by the action of a cam 69 on switches 66, 67. The carriage 54 has two pairs of sliding armature electric motors 62, 63 and 53, 77, the first pair being for horizontal movement at a normal and reduced speed, respectively, and the latter pair for vertical movement of the grippers at normal and reduced speed. Each pair of motors is housed as a single unit, their driving shafts being collinear and coupleable by means of a clutch system 205, 206 (Fig. 10, not shown). A rope 50 subject to varying strain causes reversal of motor 77 and a safety device is provided to prevent horizontal and/or vertical movement of thegrippers should this rope break. The programming of the machine's operation is described in conjunction with a circuit diagram (Fig. 9, not shown).

Title: Improvements relating to stentering or like machines
IPC: B65H23/028
Filed: 1943-10-22
Abstract: 568,965. Stretching fabrics. DALGLISH, J., and LAURIE, K. S. Oct. 22, 1943, No. 17410. [Class 42 (i)] The chains of a stenter are driven individually by means, e.g. a series wound D.C. motor, with drooping characteristic, providing for a speed reduction with increase of drag torque, and vice versa, there being positioned a mechanical synchronizing connection between the chaindriving means so that if one tends to vary in speed in relation to the other, a correcting torque is applied through the mechanical interconnection. The chains 1, 2, driven by separate motors 5, through gearings 6, both motors and gearings being supported by the side rails 4, are adjustable therewith transversely of the machine. The jigging motion of the rails 4 is imparted by a variable-speed electric motor 15, through gearing 17, crank disc 16 and linkage 18, 19, 22, the side rails 4 being pivoted at 12 to cross-rails 8 pivotally attached at 9 to supports 10. The linkages 18 and 22 are adjustable by turnbuckles 25. The motors 5, which may be A.C. or D.C. with a speed range of 5 to 1, are each furnished with an extension shaft 30, mechanically interconnected by a shaft 32 through worm and worm-wheels contained in casings 36. The worms &c. are feathered to the shafts 30, 32, for relative motion thereto, and the casings 36 move also on cross supporting rods 37, in order to allow for the cross adjustment and jigging motions. To allow for weft straightening, a clutch 39 is positioned in the synchronizing cross-shaft 32 so that it may be disconnected to allow one motor 5 to be rotated at a faster rate than the other. The motors 5 are connected to the same control gear. Cross adjustment is effected by a reversible motor 28 or, alternatively, by a drive from the cross-shaft 32 which may also operate folders and the jigging mechanism.
