Abstract: 783,216. Cutting lengths from filamentary synthetic material. BROSSE & J. DUPONT REUNIS. July 14, 1955 [July 24, 1954], No. 20439/55. Class 87(2). [Also in Group XXIII] In a brush tufting machine the tufts are cut from a continuous layer of synthetic fibres fed to the tufting tool by an electro-magnetically operated reciprocating gripper system, the cutting, being effected by the opposed surfaces of the tufting tool and the front gripper. Cutting. The layer of fibres is fed to the tufting tool 62, Fig. 6, through a channel 22a. A U-shaped member 511 carried by the tool is spring urged against a facing plate on the front gripper 461, the cutting being effected by the opposing faces of the member 511 and the plate 510 as the tool moves at right angles to the plane of the drawing. Feeding. The feeding is effected by a rear gripper which grips the fibres and moves forward pushing them through a front gripper into the tool, the front gripper thereupon closing while the rear gripper opens and moves back to its rearward position ready to feed a further length of the fibres forward. Each gripper comprises upper and lower members 498, 460, Fig. 5, urged apart by springs. The upper member has a recess in which is located a ball 501 mounted on a lever 505 coupled to a rod 504. This rod carries at its lower end a coil 505 located in the radial magnetic field of an electromagnet 502. Reversal of the direction of current in the coil causes the coil to rise and thus the fibre layer to be gripped in the cavity 22. The reciprocating movement of the gripper is accommodated by rotation of a mounting plate 508 on a ball race 509 and by the ball 501 sliding along the lever arm 505. The length of the fibre layer cut off is determined by the length of the layer fed forwards and the position of the cut. The latter is determined by the position of the front gripper, whilst the former is determined by an extension on the rear face of the front gripper which determines the forward limit of movement of the rear gripper and by an adjustable stop which determines the rearward limit of movement of the rear gripper. The positions of the front gripper and the stop are varied by means of cams so that the appropriate length of the layer is cut-off for each tuft. The reciprocation of the rearmost gripper is effected by an electro-magnetic system, Fig. 4 (not shown) similar to that shown in Fig. 5. Specification 783,343 [Group XXIII] is referred to.

Title: Improvements in mining machines
IPC: E21C27/46
Filed: 1947-07-31
Abstract: 647,491. Mining-machines. MAVOR & COULSON, Ltd. (Vogel, W.). July 31, 1947, No. 20710. [Class 68 (i)] In a machine for mining minerals having a wedge cutter 16, 17, 18 which shears the mineral from a seam, the force exerted by the hydraulic ram 9 acting on the wedge is increased in the direction of shear by a resonant system built within the wedge-carrying body, 4, without, however, any increased reaction on the anchoring jack 12 taking the reaction of the ram 9 as the cutter head advances. The resonant system comprises a heavy block 26 mounted between springs 34 secured to the body 4 and capable of oscillation along guideways 28, the oscillations being due to a rod 30 reciprocated by an eccentric 24, the rod acting on the block 26 through the intermediary of auxiliary springs 29 mounted between the end shoulders of the rod and the block 26. The magnitude of the oscillatory force can be made equal to the thrust of the ram so that the forward thrust on the wedge head ranges from twice the normal thrust of the ram to zero. Since the mass 26 does not oscillate in the cutting plane of the wedge, lateral oscillatory forces are also set up but these forces can be eliminated by incorporating in the wedge a spring-biassed lateral oscillating mass oscillating at right angles to the mass 26. In a modified form the oscillatory force may be augmented by having a series of oscillating blocks; each oscillating at twice the rate of its predecessor. The machine may be double or single ended and consist of an anchorage body 6, Fig. 1a (not shown) and a wedgecarrying body 4, which have movement relative to each other due to a piston cylinder assembly 9 or the wedges may be carried on an endless track chassis.
