Abstract: 252,960. Baker, D. Oct. 1, 1925. Charging.-In charging cupola or like furnaces with different materials, the latter are assembled in required proportions and in evenly-distributed horizontal layers, and the complete charge deposited into the furnace in a substantially vertical direction so that the layer formation is preserved. The invention is shown applied to a cupola furnace 64, Fig. 8, the supplies of different varieties of pig iron, coke, and stone being contained in trucks 13, Fig. 1, and bins 34, 36 respectively. A truck 15 carrying a hopper 16 is mounted on a track 12 running below the shoots 33, 35 of the bins 34, 36 and having a portion of its length arranged on a weighing-platform 17. The pig is charged into the hopper 16 by a magnet 22, Fig. 2, carried by a car 21 running on the arm 20 of a crane 18, the standard 19 of which is rotatable in the base 26 by a fluid-actuated piston 27 operating through link 31 and arm 29. Vertical movement of the magnet 22 is effected through a fluid-actuated piston 23 operating in a cylinder 25. To ensure that the various materials are distributed in even layers within the hopper, the latter rests on a rotatable table 39, Fig. 3, carried on the truck 15 and actuated by a motor 43 through rack-andpinion gearing 41, 42. When the hopper has been fully loaded it is lifted by an overhead telpher 55 which is traversed on rails 56 and deposits the hopper on a car 60, formed as an open frame and supported on a track 61. A rod 67, connected to the car 60, is operated by a fluid-actuated piston working in a cylinder 66, to push the car into a position immediately over the shaft 64, in which position the hopper doors are opened to allow the charge to fall vertically. into the furnace. The hopper 16 is closed at its lower end by pivoted doors 48 which, when the hopper is lowered on to the truck 15, are pushed into the closed position by plates 45 supported on springs 47; the doors are then locked by curved bolts 71, Fig. 5, which are moved to engage in lugs 50<1> by a hand-lever serving to force outwardly a rod 51 having aT-head 52 provided with rollers 53 which bears against the bolts 71. When the hopper is in position over the furnace, the locking mechanism is released by a fluidactuated plunger 70 which is arranged to deliver a sharp hammer blow on the rod 51 and be immediately withdrawn to allow the latter to clear the plunger as the doors 48 fall open.

Abstract: 880,176. Fish, dressing. FISADCO Ltd. July 18, 1960 [July 17, 1959], No. 24673/59. Class 28 (2). A cod &c. is pulled head first, by chain conveyer hooks 3, past a belly-slitting knife 3 which is automatically raised to cut through the lug bone structure, then lowered to just slit the belly skin and finally lowered further at the vent to clear the fish. The final lowering is controlled in accordance with the length of the fish by feeler levers 65 and 68. A spring 26 urges the knife carrier 16 to rock clockwise about pivot 24. A stop 27 engaging the side of 25 limits the clockwise movement of 23. One arm 30 of 23 lies in the path of a pin 31 on a plate 32 bolted to a conveyer wheel 2. When pin 21 engages 30, lever 23 is rapidly rocked to raise the carrier 16 and knife 15, and immediately the pin 31 disengages from 30 so that the carrier rocks downwards. The other arm 35 of 23 projects laterally to be engaged by a rotary eccentric abutment 34 on a vertical shaft 36 which on rotation carries the abutment 34 out of registration with the arm 35. The carrier raises the knife upward to the maximum to out the lug bones. When pin 31 clears 30 and the carrier swings back to hold the knife in bellyskin slitting position a rock 40 carries two thickness feelers 47 extending down to bear on each side of the fish and spreads them apart. A lever 70 carries a roller bearing against a cam rail 72. Specification 878,957 is referred to.

Abstract: 757,460. Vehicle couplings. FERGUSON, Inc., H. Aug. 25, 1954 [Sept. 9, 1953], No. 24693/54. Class 103 (5). [Also in Group I] A tractor of the type having power lift links operating a drop hook 45, Figs. 2 and 4, is also provided with a forward coupling member 10 so that the tractor may be coupled to a side frame 13. The frame 13 has a ground wheel 14, a castor wheel 35 or a skid, a screw jack stand 36 and a tongue 34 provided with an eye 44 engageable with the drop hook 45. The frame member 31, Figs. 6 and 7, has a clevis 60 with a cross-pin 61 which may enter V- shaped jaws 64, 65 on the tractor, and the jaw 64 is formed by spaced parallel sides which contain a latch 68 pivoted at 69 and urged to a closed position by a spring 71. The latch includes a downwardly extending ear 70 which may close the entrance to the jaws, and is provided with a slot 72 receiving a spring- biased pawl 74 pivoted at 75 to the ear 70 and including a lip 76 engageable with the extremity of the jaw 64. In operation the frame 13 is initially supported by the wheels 14 and 35 and the stand 36 with the eye 44 below the hook 45. The hook 45 is then lowered and the tractor reversed to pick up the eye 44, the driver sighting the edge 58 of the tongue 34 with the telescopic link 55, and reversing the tractor until a position stop 59 engages a cross-arm 52. The hook and eye are then raised until the snap latch of the link 55 engages and holds the hook in position, in which position the hook is closed by a latch 50 and the wheel 35 is clear of the ground. Further reversing of the tractor causes the frame 13 to converge upon it, until the cross-pin 61 strikes the pawl surface 80, Fig. 6, and forces the pawl to pivot to a position where the lip 76 clears the jaw 64. Further movement of the pin 61 causes it to strike the latch surface 81 and raise the latch to permit the pin to enter the jaws. The springs 71 and 79 then return the latch and pawl to their closed and locked positions. The stand 36 may then be raised by rotating the screw 39 from the driving seat. Quick uncoupling may be done in the reverse order, the pawl 74 being released by pressure of the driver's foot against an extension 78 of the pawl. Reference has been directed by the Comptroller to Specification 732,673, [Group I].

Abstract: 713,859. Eddy current couplings. CONE AUTOMATIC MACHINE CO., Inc. Oct. 26,1951 [Nov. 1, 1950], No. 25149/51. Class 35 [Also in Group XXII] A mechanism for adjustably conclating tool feed with rate of cutting in machine tools comprises rotary driving and driven members, an eddy current clutch between the members including an eddy current clutch coil, a generator driven by the driving member, a generator driven by the driven member and means controlled by the relative voltages from these generators for energizing said coil and operator actuable means for varying such control in accordance with the desired rates of speed of rotation of said driven member to said drive member. An electro-magnetic dragtype clutch is used to provide the operator controlled speed-rates changing mechanism. This comprises a driven shaft 51, Fig. 3, and driving shaft 50 mounted in anti-friction housings within a casing 36 A spider 54 having a ring 55 of iron or other magnetic material is keyed to shaft 50 and surrounds a drum 56 keyed to shaft 51. The latter comprises alternate pole-pieces 57, 58, which are energized through a solenoid 59 arranged between them and thus establish a magnetic drag between the spider and the drum. The amount of slip occurring between these parts may be varied by varying the amount of energization of the solenoid. For this purpose a pair of alternating generators 61 are provided on the shafts 50 and 51 which produce a voltage proportionate to the speed of rotation of their respective shafts. Current from these alternators is rectified through two-way rectifiers 65, 66, the direct current passing to opposite ends of an operator-controlled potentiometer 660, the slider of the latter and the mid-point of the opposite side of the circuit being connected to a control box. The latter contains a Wheatstone bridge control device which receives energy from the power leads 70, 71, and delivers a controlled current through leads 72, 73, to the brushes 74, 75, for supplying the solenoid 59. The bridge device automatically operates to change the excitation of the solenoid following manual adjustment of the potentiometer 660 and thus carries the rate of rotation of the shaft 51 relative to the driving shaft 50.
