Title: Upsetting machine for the manufacture of headed bolts and other similar objects
IPC: B21K1/44
Filed: 1934-12-07
Abstract: 429,489. Forging bolts &c. KUHNE, J., 34, Burgunderstrasse, D³sseldorf, Germany. Dec. 7, 1934, No. 35173. [Classes 83 (ii) and 83 (iv)] Relates to forging bolt heads, screws and similar objects in apparatus of the type in which the rod is confined in a bore and the portion to be upset is fed gradually to the heading ram, and consists in a construction in which the matrix or holder is made stationary or advanced or retracted through mechanical means. The matrix or gripping part 5 is enclosed in a holder 4, connected by bolts 10 to a cross piece 11, which in turn is connected to a lever 15 pivoted at 14 and connected by a link 16 with a lever 17. The lever 17 has a roller 18 running in a groove in a cam 20, the groove being mostly concentric for maintaining the matrix stationary, but having an eccentric portion for advancing and retracting same. The heading die 9 is mounted on a carriage 2 reciprocated by a crank handle or eccentric and communicates motion to a rod 30 carrying a block 31 provided with a pivoted spring- pressed pawl 32. The pawl is capable of oscillating a pivoted lever 29 or of being freed therefrom by tripping against a cam surface 36. The rod 30 passes through the rod 29 and the latter has a pin 33 for engaging the pawl 32. One end of the lever 29 works in a recess 24 of a rod 23 freely sliding through the crosspiece 11 and attached to, or integral with, a rod 22 carrying the punch or ejector 21. In operation, blanks, previously heated and cut, are brought between the upsetting die 9 and the die 5, the carriage being in the retracted position shown, and the punch or ejector coupled to the carriage through the lever 29, pawl 32 and rod 30. The die 5 and its holder are in the position shown and maintained thereat by the roller 18 running in a concentric part of the cam groove. The carriage 2 now moves towards the blank and carries with it the punch 21. The blank is encountered by the heading die and forced into the matrix 5 until it engages the punch 21, which meanwhile has stopped, the heading die acting on a part of the blank outside the matrix. Bv the roller 18 running onto an eccentric part of the cam groove the matrix is moved to free the remainder of the part to be upset. Subsequently the carriage moves back and carries the punch 21 to eject the finished blank. In order to avoid excessive wear of the die and ejector due to slag &c., rinsing water is passed through the die holder and die, and the ejector pumps it forwardly and forces the finished work from the die. Making balls.-The press is stated to be applicable for the manufacture of balls from rods.

Abstract: 985,735. Dispensing liquid by gaseous pressure. REYNOLDS METALS CO. Sept. 5, 1963, No. 35195/63. Heading F1R. In a liquid dispensing container having a pressurized propellant gas receptacle 84 Fig. 1 supported within a closed vessel 10 and a faucet 42, a pressure fluid filled flexible walled container 130 is subjected to the pressure of gas supplied to the container so that movements of the flexible wall acts upon a displaceable valve member 120 to control the gas flow. Faucet 42 is opened by pulling handle 54 forwardly against the pressure of the spring 64 and the liquid in container 10. When the gas pressure in chambers 100 and 95 drops, bellows 130 expands and causes button 128 to push the stem of a tyretype valve 120 to release gas through valve 120 chamber 95 and check valve 106 (Fig. 2) to chamber 100. In a modification, the valve is opened by a diaphragm 142 and cup 134 may be fitted with a valve for charging bellows 130 or cavity 140. Pressure is relieved from chamber 100, receptacle 84 or 84A and cavity 95 respectively by valves 152, 160 and 194. Rubber plugs 174 have a passageway through which a propellent gas charging needle is inserted to force gas, e.g. isobutane with or without acetone, through valve 168 into receptacle 84 or 84A. The disc cover 176 e.g. of plastic and/or cover 184 may have a rupture part 186 to release pressure when any of the relief valves operate. In a further modification a heat sealable impervious film e.g. of polypropylene, is sealed to the upper surface of the support 86.

Abstract: 620,327. Radio signalling; aerials; radio navigation. FAULKNER, A. W. Nov. 27, 1946, No. 35219. [Classes 40 (v) and 40 (vii)] A signal transmitting unit jettisoned from aircraft when, a crash occurs or is imminent, comprises a radio transmitter and a recording device on which the navigator records from time to time, e.g. the location of the aircraft, and means automatically obliterating superseded signals from the record. The unit is carried in guides in a catapult 15 with spring ejector 16 released by electro-magnetic catches 26, 27 energized by a battery 28 and by an inertia switch 29, hand-switch 43, nose or wing-tip trip switches or a thermal switch indicating fire. The unit, enclosed in a rubber sheath 13, is buoyant, and maintained vertical by weights 14. After ejection a parachute pack 23 automatically opens and extends a telescopic aerial 30, the parachute, being connected to the unit by a scissors hook, automatically being disengaged on landing. A reel of wire may be released on landing to have an anchoring effect in water. A battery 35 on the aircraft energizes the recorder driving motor and obliterating head when the microphone 34 is lifted, but on the unit connector 32 being disengaged an internal battery of the unit is connected and the obliterating head is disconnected. The recording is on an endless plastic tape containing magnetizable particles and is transmitted repeatedly until the unit battery is exhausted, the length of tape being sufficient to ensure one complete recording being always available. An S.O.S. signal may automatically preface each transmission or an auxiliary record indicating fire may be introduced by a thermal switch in the case of fire. Two or more separate records selected by a microphone switch 36 may be made. According to the Provisional Specification, in case the unit does not land vertically, two or more antennae may be projected in different directions from it on landing, and a switch may connect the transmitter to the one properly erected.

Patent GB-949192-A (GB)
Title: Masking frame for photographic printing apparatus
IPC: G03B27/58
Filed: 1960-10-19
Abstract: 949,192. Masking frames for photographic printing apparatus. AGFA A. G. Oct. 19, 1960 [Oct. 31,1959], No. 35891/60. Heading G2A. A masking frame for photographic printing apparatus has four adjustable masking strips and a mask setting means arranged to move through transmission means both pairs of opposite strips to vary the corresponding dimensions, the two strips of each pair moving in opposite directions and the transmission means being geared to give a constant ratio between the two dimensions. As shown (Fig. 1), masking strips 4, 5 are adjustable in opposite directions respectively by means of sliding racked rods 8, 9 engaging a pinion 14 fixed to the shaft of a mask setting means 15. Similarly, strips 6 and 7 are coupled by racked rods 10, 11 to a pinion 16 on said shaft, the coupling between the pinion and shaft being here releasable. With the pinion 16 coupled, adjustment of the knob 15d results in variation of the image area 3 at constant length to width ratio. A pointer 61 on the mask 6 co-operates with a scale 58 to indicate length of printing paper and width is indicated by a pointer 35 on the rail 8 and a scale 36. In order to set the frame for different length to width ratios, first the desired length is set by rotation of a knob 15d (Fig. 2) of the setting means 15, and then the desired width is set by rotation of the knob 15d with the knob held depressed against loading of its spring 33. Depression of the knob 15d results in disengagement of a pin 23 in a pinion 20 from a hole 22 in a nut 21 secured to the setting means 15 and as a result, pinion 16, connected to pinion 20 by a bushing 16a is uncoupled from the setting means 15. In order to prevent accidental movement of the pinion 16 out of its set position during adjustment of the width, a slide member 24 engaged by a bevelled edge 25 of the nut 21 is arranged through a spring 26 to bring a slidable toothed member 29 into engagement with the pinion 16. Means for setting the width of the margin include stops 52, 52a and 55 respectively on bell crank levers 49, 56 and 53. These levers are coupled through pin and slot connections and slidable racks 45, 43 to a margin setting means comprising a pinion 40 and a setting spindle 37, the pin and slot connections being arranged to allow for movement of the masking strips without affecting the width of the margin. A fixed scale 39 and a pointer 38 co-operate to indicate the width of margin set. As the scale 58 is mounted on the rod 43, the margin must be set before said scale 58 is used to set the paper length. The frame is described as applied to an enlarger 1 in which images are projected upwards through a glass plate 3. In a modification (Fig. 3 - not shown) instead of the two stops 52, 52a being on separate bell crank levers, a single bell crank lever may be arranged to control a single slide member having two stops thereon. Differently proportioned margins may be catered for by providing different transmissions between the setting device 37 and the racks 41.
