Abstract: 966,329. Discharging articles. L. SCHULER A.G. Aug. 10, 1961 [Sept. 9, 1960], No. 28899/61. Heading B8S. A stack 10 of blanks carried by plate 4 is pushed by pawl 26 actuated by fluid cylinder 24 rightwards along the rollerway 2 till it is positioned above lift plate 12. Plate 4 has aperture 11 therein which permits lift plate 12 to rise under the actuation of fluid cylinder 14 so as to lift stack 10 up to a position where the top blank is engageable by pawl 15 carried by slider 16, actuated by cylinder 18. Pawl 15 thus engages the topmost blank and discharges it from the stack on to platform 7 ready for insertion into a press. The topmost blanks are thus discharged one by one till lift plate 12 has risen to the position shown in Fig. 1. At this stage pawls 28 which have been pressed back by the elevation of the stack now have room to move inwards to the position shown so as to support the topmost blanks. This permits lift plate 12 to descend and plate 4 now empty to be removed and the next full plate 4 to be inserted into position. Whilst this is taking place, the topmost blanks of the stack forming a reserve stack are discharged one by one by means of the reciprocating pawl 15, the step-bystep elevation of the reserve stack being effected by the step-by-step movement upwards of pawls 28 carried by arms 27 actuated by fluid cylinder 31. In this way plates are fed from the top of stack 10 one by one even whilst the next stack is being put into place. The operation is thus made continuous. Plate 4. Fig. 3.-Plate 4 carries discs 6 which each carry a rod 5 and the discs 6 are rotatable so that the positions of the rods 5 are adjustable to suit different sizes of blanks. When plate 4 reaches the position above lift plate 12 it is held fixed by wedge 22 operated by cylinder 20. Magnetic device. Fig. 4.-When the topmost blank of stack 10 is discharged sideways by pawl 15 the discharge is assisted by magnetic rollers 40 which take some of the weight.

Filed: 1936-10-26
Abstract: 483,676. Filling and emptying tanks. ELLOR, J. E. Oct. 26, 1936, No. 29101. [Class 21] [Also in Groups XXIX and XXVIII] In a liquid-fuel tank installation for aircraft of the type in which at least two tanks A to which air under pressure is supplied, deliver to a common pump, each tank is divided into at least two compartments B<1> ... B<6>, or is replaced by a series of two or more tanks each forming a compartment, each compartment communicates with the next in the series by a passage D, D<1>, D<2> at or near the bottom of the former, the pressure air is supplied only to the compartment B<1> at one end of the series, the fuel outlet to the pump is from the compartment B<6> at the other end of the series, and means are provided for the escape of air from the last compartment when the fuel therein is exhausted. The fuel is forced by the air pressure from one compartment to the next, so ensuring a supply of fuel in the final compartment from which the pump draws until the fuel is exhausted. Should one tank be emptied before the other the relief of the air pressure in it prevents the delivery of air to the pump and the resulting failure to supply fuel from the other tank. In the construction shown, each tank A is divided into six compartments by partitions formed with apertures D, D<1>, D2 at the bottom through which the fuel passes successively through them from the compartment B<1>, to which air is supplied by a pipe C<1>, to the compartment B<6> to which the pump suction pipe A<1> is connected. Within the compartment B<6> is a cylinder E, perforated at the top and bottom and containing a metal float F slidable on a rod F2 connected by a universal joint to the stem of a spring-pressed mushroom valve F4 which normally closes the orifice of an air-escape pipe G. When the fuel level falls sufficiently the float bears on a flange F3 on the rod F<2> and opens the valve. Air-vent pipes H4 lead from each compartment into the wall H of the filling-opening, the outlets being closed by the tapered body H<1> of the screwed plug which closes the opening. In a modification, each tank A is replaced by an uncompartmented main tank connected to a separate small tank to which the pump suction pipe is connected, and in which the air pressure relief valve is arranged. According to the Provisional Specification the float device in the final compartment or tank may operate to close the outlet to the pump suction instead of relieving the air pressure when. the fuel level falls.
