Title: Crimping tool
IPC: H01R43/042
Filed: 1948-08-18
Abstract: 651,930. Jointing by stamping. AIRCRAFTMARINE PRODUCTS, Inc. Aug. 18, 1948, No. 21767. Convention date, Aug. 19, 1947. [Class 83 (iv)]  A crimping-tool comprises opposed jaws pivotally connected intermediate their ends  and actuated by a toggle mechanism comprising a lever pivoted at one end to one of the jaws. a link connecting an intermediate point of the lever to the other jaw and means for applying a toggle operating force to the other end of the lever. The main frame of the tool comprises spaced plates 66 and 67, Fig. 2, to the lower ends of which is secured the cylinder 88 of a pneumatic operating device. The other ends of the plates comprise prongs between which bridge members 77 and 78 are secured by means of headed pins 70 and spring clips 71. The crimping- dies 13, 14 are mounted on jaws 72, 73 pivoted between the members 77 and 78 at 75, 76 and actuated by a toggle 80, 81 at their inner ends. - A roller 74 keeps the jaws in longitudinal alignment. Cylinder 88 contains a piston whose rod 87 carries at its upper end a roller adapted to move along slots in the frame plates 66, 67 and which is secured by links 91, 92 to the jaw-actuating toggle. A slight depression of a trigger 123 depresses a plunger 115 so as to close an exhaust port 114 and depress a ball valve 102 so that pressure air from a pipe 96 which leaks past a ball valve 104 may pass by way of a pipe 97 to the cylinder 88 and cause the jaws to move to a position in which they lightly grip the work. Further pressure on the lever moves the ball 102 downwards and causes a hollow stem to press on and open the ball valve 104 thus allowing the full air pressure to operate the piston to apply a crimping pressure to the jaws. In a modified form, the tool is mounted on a bench and the toggle actuated by a pedal. In another modification, Fig. 8, one jaw 11 is integral with a hand grip portion 10 of the tool and the other jaw 17, hinged to the fixed jaw at 19 is operated by a toggle against the action of a spring 25. The rear part of the tool comprises a cylinder 33 containing a piston 35 with a forwardly projecting block 39 adapted, on the forward movement of the piston, to abut and move a roll 31 at the end of an extension of one of the toggle levers 21. On the inward movement of a lever 27 which normally projects through a slot 29 in the handle portion 10, a piece 28 integral with the lever bears on the toggle lever 21 so that the jaw 17 is moved into a position to grip the work lightly. Depression of a trigger 44 projecting from the lever 27 operates through a lever 47 and rod 49 to open a ball valve 53 to admit fluid pressure to the cylinder and so apply dimpling pressure to the upper jaw. In a modification the lever 27 and trigger 44 are replaced by a single lever with a spring hinge portion so that on pressing the lever gripping pressure is applied to the jaws and then the hinge portion of the lever bends to allow the operation of the rod controlling the ball valve. Specification 585,507 is referred to.

Abstract: 641,810. Radio signaling; receiving systems; aerials. STANDARD TELEPHONES & CABLES, Ltd. Aug. 8, 1947, No. 21922. Convention date, Oct. 29, 1946. [Classes 40 (v) and 40 (vii)] A radio communication system between two points on the earth's surface comprises means for transmitting signals towards the moon and means for selectively receiving echo signals reflected from portions of the moon's surface. The receiver for the reflected energy may comprise a paraboloidal reflector 6 with screen 7 in its focal plane carrying three spaced dipole aerials 8, each connected by diversity reception channels 15 to a common output. The screen 7 is adjustable by linkage 9 to correct position as viewed by visible light through a central reflector aperture 14, and the dipoles also may be adjustable. The reflector may be adjusted to face in any direction by drive means 12 and rotated by a clockwork drive 13 to follow the moon. The reflector alternatively may be annular or in two partannular sections, each formed of individually set up and adjustable portions. In the sytem of Fig. 7 duration or phase-modulated pulses are used and the receiving antenna comprises concentric series of dipoles 32-35 connected so that their energy is additive and applied to separate channels of a receiver containing delay networks and phase adjusters whereby allowance is made for the different times of reception of signals reflected from different concentric areas of the moon. The delay networks retard all signals except those from the outer series of dipoles, the latter receiving only from the remoter area of the moon. A common oscillator 39 beats with the signals in the respective channels. Four separate receivers for diversity reception may be provided corresponding to each quarter circle area in the focal plane of the reflector, with the dipoles in each quadrant separately connected to a receiver.

Patent GB-416706-A (GB)
Title: Improvements in liquid dispensing apparatus
IPC: B67D7/08
Filed: 1933-08-04
Abstract: 416,706. Liquid - dispensing apparatus; counting - apparatus. WAYNE CO., Fort Wayne, Indiana, U.S.A. Aug. 4, 1933, No. 21988. Convention date, Aug. 15, 1932. [Class 106 (i).] In a liquid-dispensing apparatus having a pump delivering liquid to a meter, the meter is connected to registering mechanisms for ascertaining the quantity and the cost of the liquid dispensed, and a plurality of selectively adjustable driving mechanisms for the cost counter are provided to compensate for changes in the price per unit quantity. In the apparatus described the pump operated meter drives a shaft 52, Figs. 2, 3, and 4 journalled in a casing and operatively connected through bevel gearing 64, 66 with the driving shaft of the quantity registering counter 70. On the shaft 52 is secured a gear cone 72 consisting of a set of stepped gear wheels 74 and arranged adjacent a fixed gear wheel 76. The shaft also carries three rotatable sleeves 84, 98, and 116 interconnected by a set of pinions and planetary gears. The sleeve 84 is formed integral with a gear 82 and carries a gear 88 which supports the pivots 92 of a pair of pinions with toothed surfaces 90, 94 of different diameter. The teeth 90 co-operate with a toothed portion of the gear 82 and the teeth 94 mesh with a toothed portion 96 of the next sleeve 98. The sleeve 98 carries a gear 102 which supports a pair of similar planetary gears 108, 112, the gear 108 meshing with a toothed portion 110 of the sleeve 98 while the gear 112 meshes with a toothed portion 114 of the sleeve 116. This mechanism imparts an integrating or summation movement to the sleeve 116 which is communicated through gearing 118, 120 to a shaft 122'driving the cost computing counter 124. The gears 82, 88, and 102 receive their movement from gears 136, 138, and 140 secured to hexagonal shafts 128, 130, and 132. The amount of rotation imparted to these shafts is dependent on the price per unit quantity and is adjusted by shifting corresponding levers 148, 150, 152 over cam surfaces 154 with graduated apertures. When the lever 148 is set to the appropriate aperture for tenths of a cent a bell-crank 142 attached thereto is correspondingly moved along the shaft 128 to bring a pair of gears 178, 166 into engagement with the appropriate stepped gear 74. The other levers 150, 152 set pairs of gears 180, 168, and 182, 170 respectively, Fig. 5, for the units and tens of cents values. A movement of any of the gears 166, 168, 170 into engagement with the fixed pinion 76 renders the corresponding shaft 128, 130, or 132 inoperative. In a modification a differential bevel gearing is employed instead of the planetary form above described.

Abstract: 189,214. Brown, E. O. Aug. 24, 1921. Moulds; reciprocating-mould-table machines; tamping-machines.-A machine for moulding concrete blocks &c. comprises in combination a hopper a, a drop hammer c, and a mould carriage l reciprocating thereunder, the carriage l having a surface x, which cuts off the supply of material from the hopper, and pivoted side, front, and partition walls. The hopper a tapers from bottom to top, and is provided with an adjustable side plate, thus allowing the moulds to be supplied with excess material which forms a cushioning surface for the blow of the hammer c. The latter is supported on a rod d in a frame b, and is maintained in its raised position by a cross bar q pivoted at one end r and held by a spring s so as to engage a notch in the rod d. On rotating a hand wheel k, the carriage is moved by rack and pinion gearing on the shaft 'i from under the hopper a to beneath the hammer c, and on its movement strikes, by means of a projection w, a pivoted tappet v attached by a wire to the bar q, and thus releases the hammer c. Further rotation of the wheel k causes the hammer to be raised by the chains f and the carriage to pass under a scraper, which removes excess material, to a position where, the sides of the mould can be pivoted outwards and the moulded blocks removed on their pallet. The pallets 14, Fig. 4, are preferably of the stool type, having feet 32 which hang down on each side of the mould carriage, and may be used inverted, the front wall of the mould in such case being fixed in position and the pallets being removed vertically. The plunger head may comprise a plate 37, Fig. 8, having a wooden face 38 and a channel shaped metal box 39 with slots 41 corresponding to the mould partitions. A modification is described in which the mould carriage is driven and reversed through clutch mechanism.
