Title: Improvements in or relating to furnace charging apparatus, manipulators for use in forging and other like apparatus
IPC: B21J13/10
Filed: 1945-03-21
Abstract: 596,664. Furnace charging machines. WELLMAN SMITH OWEN ENGINEERING CORPORATION, Ltd., and KAY, I. March 21, 1945, No. 7168. [Class 51 (ii)] [Also in Groups XXII and XXX] A forging manipulator, furnace charging apparatus and like work-handling apparatus comprising a work carrying member, such as a peel, adjustably mounted on a movable carrier, and provided with work-gripping means, the peel and the work-gripping means are operated by separate hydraulic cylinders each connected to a common compressed air tank, the internal volume of which is reduced by an, increase in the pressure within the peel operating cylinder with a consequent increase in the pressure within the cylinder -operating the workgripping means. The invention is described as applied to a forging manipulator having a pair of hydraulic cylinders 2 for moving the peel in a vertical'plane and another hydraulic cylinder 3 for operating the work-gripping members at the end of the peel. The air pressure vessel comprises a cylindrical tank 4 with ends 5 through which is fixed an inner tube 6 which communicates with the annular space of the tank by way of peripheral holes 7. Operating within one end of the tube 6 is a hollow piston 8 guided at its other end by a member 12 projecting-into the piston from a fixed end member 19 supported from the tank by taper extensions 18. The interior of the cylinder 3 is connected to the interior of the piston 8 by way of a pipe 16 and a bore 14 through the member 12. A similar hollow piston 9 working in the other end of the tube 6 is in communication with the hydraulic fluid in the cylinders 2. The cylinders 2 and 3 are supplied with hydraulic fluid under the control of the operator, at pressures of 450 and 800 lbs. per square inch respectively and the tank is filled with air at a pressure of 85 lbs. per square inch. The internal and external surfaces of the pistons 8 and 9 are such that admission of fluid to the cylinder 3 to cause the gripping of the work moves the piston 8 fully inwards, thereby causes a rise of air pressure in the tank 4 of approximately 6 per cent. With admission of fluid to the cylinders 2, the piston 9 remains in the position shown. If however, during a forging operation an overload is imposed on the lifting or pivoting cylinders 2, the piston 9 is forced inwards, causing a further rise in the air pressure with a consequent rise in the gripping pressure. In modified forms, the single tube 6 is replaced by two shorter tubes both entering the air tank through the same end wall or through the curved side wall. In a further modification, Fig. 5, the shorter tubes 6a instead of projecting into the air tank, are closed at their ends and are connected to a common air tank by pipes 20, 21.

Each lug of each of the two pairs of lugs adjacent its junction with the central body has an integral reinforcing portion 12a, 13a, 14a, 15a extending from the central body in the direction of the extension thereof of the adjacent lug with the reinforcing portions of the one pair of lugs in each case forming a scaffolding tube engaging extension of that central body seating which, in securing the tube, coacts with that hinge jaw which is associated with the other pair of the two pairs of lugs. The lugs 12a and 14a have an outer corner of right angle configuration in crosssection to provide a sharp edge 12b, 14b, curved about the axis of curvature of the adjacent seating so that it can bite into the scaffolding tube and in the case of a vertical tube prevent the coupling slipping down the tube when under load. The mass of each of the bolt hinging lugs 13, 15 is substantially that of each diametrically opposed jaw hinging lug 12, 14 respectively by eliminating the metal of the jaw shown at 13c in Figure 1.

Class 135 A predetermined relationship between the speeds of two independently driven members, one of which is driven by a hydraulic motor B, is maintained by apparatus comprising positivedisplacement pumps H1, F1, driven respectively by the hydraulic motor and by the other independently driven member which, as shown, is driven by a hydraulic motor A, a conduit G interconnecting the outlet of the pump F1 and the inlet of the pump H1, and a spring-loaded valve E subject to the pressure in the conduit between the pumps F1, H1 and controlling an escape from a hydraulic supply conduit B3 to the motor B so that a variation in pressure in the conduit G, as a result of a departure from the required speed relationship, results in a corrective change in the speed of the motor B. The pump Fl draws from, and the pump H1 discharges to, a conduit C connected with a reservoir C1, and valves J, J1 interconnecting the inlet and outlet of the pumps F1, H1 guard, respectively, against pressure in the conduit G falling below that in the conduit C and excessive pressure in the conduit G. The predetermined speed relationship may be varied by altering the displacement of either or both of the pumps F1, H1 or by adjusting an escape orifice G2 in the conduit G. The sensitivity of control may be varied by adjusting the displacement of both pumps F1, H1 in the same sense. The motors A, B are supplied by pumps A1, B1 the pump A1 being driven at constant speed and having means A6 for adjusting that speed or for varying the displacement. In a modification, the motors are supplied in series from a common pump, the second motor being of lesser capacity than the first, and the valve E controls escape of liquid from the conduit between the motors.

Abstract: Ferrous sheet stock is coated with aluminium to a thickness, if necessary after working, of .0001-.0003 inches and is then heated to 1050-1750 DEG F. to cause the aluminium to alloy with the iron. Iron or steel stock is first coated with aluminium, e.g. by dipping as described in Specification 453,803, and then cold rolled to reduce the thickness of coating to 0.0001-0.0003 inches. The heating may be a box anneal in a non-oxidizing atmosphere such as nitrogen, hydrogen or dissociated ammonia, or a strand anneal in an oxidizing atmosphere.  The heat treated strip may be brightened by heating in dry hydrogen at 1650-1750 DEG F.  The aluminium bath may contain minor amounts of silicon and mageutectic.
