Title: Trigger mechanism and electrical instruments employing such mechanisms
Inventor: MACADIE HUGH SUTHERLAND
IPC: H01H71/24
Filed: 1965-02-22
Abstract: 1,125,962. Electric meters. AVO Ltd. Jan.28, 1966 [Feb.22, 1965], No.7583/65. Heading G1Q. [Also in Division H1] A trigger mechanism incorporating a pivoted lever 11 acted on by a pair of magnets 13, 14 controls the operation of a switch 37, e. g. in response to the deflection of an electric meter. The preferred application is as an overload cut-out for such a meter. When the meter coil 1 strikes either of pawls 4 and 5, rod 9 displaces the lever 11 away from magnet 13. Magnet 14, which is more powerful, accelerates its further displacement into a position in which it strikes a second level 21, and so releases the latter's latching engagement with switchoperating lever 26. This lever is biased by a spring (not shown) so that it moves clockwise and allows switch contacts 38 to open. Once released, lever 26 continues its clockwise movement and entrains an arm 32 of the two armed spring 33 which rotates about a pivot 35 so that its other arm 34 turns lever 21 anti-clockwise. This in turn imparts anti-clockwise movement to lever 11 and eventually restores lever 11, rod 9 and pawls 4 and 5 to their initial position. At this stage, end 22 of lever 21 rests on lever 11 and the switch-operating lever 26 is at 90 degrees to the position illustrated, the switch itself remaining open. Lever 26 is returned manuallye.g. by rotating a knob (not shown) coupled to it - so reclosing the switch and at the same time engaging the end 23 of lever 21 and returning it to the initial latched position shown. The position of the lever 26, and hence the condition of the switch, is indicated by a flag 39 carried by the lever and viewed through a window in the meter casing. An auxiliary lever 40, counter-weighted at 43, prevents inertial actuation of the trigger mechanism.

Title: Associating printed sheet material
IPC: B41F13/68
Filed: 1973-02-16
Abstract: 1397666 Sheet ordering apparatus HARRIS CORP 16 Feb 1973 [17 Feb 1972] 7838/73 Heading B8R  A collating apparatus, comprising a series of hoppers 15 which sequentially discharge sheets on to a conveyer arranged beneath the hoppers, is divided into two sections 11 and 12 one hopper 16 of the section 11 receiving printed sheets direct from a printing press 10 when gating means 31 is in a first position and one hopper 17 of the section 12 receiving printed sheets direct from the press when the gating means is in a second position. The remaining hoppers 15 of each section may be filled manually. Associated products (e.g. newspapers) from section 11 are delivered on conveyer 13 and from section 12 on conveyer 14. The arrangement is such that when hopper 10 is full, sheets are directed to hopper 17 and when hopper 17 is full surplus sheets are stacked in an accumulator 20. When the supply in hopper 17 is depleted and the press has stopped, sheets stacked in the accumulator are delivered along conveyer 45 into the hopper. If the accumulator becomes full stacks may be removed on roller conveyer 43. The hoppers 16 and 17 each have maximum and minimum pile height detectors, the delivery from these hoppers being stopped when a minimum pile height is reached to ensure that a supply of printed sheets remains for the next press run.

Title: Packaging method and apparatus
IPC: B65B29/02
Filed: 1959-03-06
Abstract: 866,354. Packaging-machines ; making bags. WARDELL, V. C. March 6,1959, No. 7883/59. Classes 94 (1) and 94(2). A machine for forming simultaneously a number of packages such as tea-bags comprises a series of hollow mandrels which are charged with the substance to be packed, a strip of sheet material then being folded to U form over the mandrels sealed at the ends, and sealed and severed between them to form a series of bags. The mandrels are inverted so that the bags become charged and are withdrawn for sealing of their open ends. The mandrels 20 are carried on a drum 22 in six rows of twelve at station A, a row is charged from funnels 19 and passes to station B where a web P of a width greater than the length of the row is fed over the mandrels, clamped against their ends by a bar 38, Figs. 9, 10, and severed. Parallel plates 40, 42, Fig. 2, then advance radially inwards to fold the strip to U form about the twelve mandrels. Clamps 48 on either side of each mandrel engage the strip against the mandrel sides and the plates 40, 42 withdraw. During advance to the sealing station C, the spacing of the mandrels in the row is reduced to give slack between them to facilitate sealing. Each mandrel is mounted on a carriage 26 slideable parallel to the drum axis on rods 28, 30. Each carriage is connected by a separate pair of rods 64, 66, 68, 70, 72, Figs. 5, 18, to cam means 60, the latter being provided at opposite ends of each row and serving six mandrels. The cam means consists of pivoted channel members 74 engaging pins 78 on extensions of the pairs of rods. A fixed ring cam, Fig. 24 (not shown), varies the angle of the members 74 to the rods and thus the spacing of the mandrels. Sealing is also facilitated by pairs of rods 55 slideable within each mandrel which are projected slightly Fig. 12, to distend the sheet material adjacent the mandrel corners. Sealing is performed by pivoted heated jaws 90. At station D, cutters 100 sever the material between each pair of mandrels to form individual bags and in passage to ejecting station E, the mandrel spacing is increased to facilitate removal. At station E the clamps 48 withdraw and the rods 55 extend fully to thrust the bags into a series of pockets 120 on a drum 105, the mandrel contents being deposited in the bags, Figs. 2, 16. The pockets close on the bag mouths leaving a portion projecting which is heat sealed by members 142, 144. At the next station, the pockets open and the bag mouth seals are gripped by jaws 162 on swinging arms 400. The arms withdraw the bags from the pockets so that they hang down in the path of a beating device 192 which destroys any faulty bags. The jaws 162 then release the packages. A known apparatus for placing the bags in cartons may be combined with the machine.

Abstract: 453,361. Electric motor controllers. SCOTT, W. H., and CLARK, H. O., Gothic Works, Norwich. March 14, 1935, No. 7962. [Class 38 (iii)] A control mechanism for an electrically-driven trawl winch comprises a controller for governing the speed and direction of rotation which is provided with a gate which, in co-operation with a setting stop which can be set in any of a series of positions in the gate, is adapted 'to limit the movement of the controller from full speed to off position for each direction of rotation of the motor and from slow speed in one direction to slow speed in the other, while permitting freedom of operation between the slow speed limits through the off position. A controller 1 is operated by handles 8 through gearing 6 and has a gate comprising a slotted cylinder 9 mounted on its shaft. A stop pin 17 mounted on a pivoted setting lever 14 may be set in any of the slots 10, 11, 12 of the gate and passes from the slot 11 to the slot 12 through a narrow slot 13. With the setting lever in a " haul-in " position the pin 17 is situated in the slot 10 and the controller may be operated from the off position to the full speed hauling in position. When the setting lever is in an "inch" position the pin 17 is in the slot 11 and the controller may be moved to give inching speeds in the forward or reverse directions. The lever 14 may also be moved to a " pay-out " position to move the pin into the slot 12 so that the controller may be moved from the off position to the full-speed pay-out position. When the lever is moved to the off position the pin 17 is in the slot 13 and the controller is locked in the off position.

Abstract: 161,565. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Flanders, W. B.). April 10, 1920, [Convention date]. Void [Published under Sect. 91 of the Act.] Grinding interfitting parts together.-In order to true imperfectly cut gear-teeth, the gear-wheels intended to operate permanently together, for example, a pinion and a large gear, are run together in mesh, and are provided with fly-wheels; abrasive is supplied at the points of contact of the wheels. The pinion 8 is carried by a shaft 14 mounted in bearings 6, and is driven at as nearly as possible constant speed through gearing 15, 16. Shafts 11, 12 are coupled to the shaft 14 and each carries a fly-wheel 9, 10 to steady the rotation of the pinion. The gear wheel 21 is mounted in bearings 22 and is connected with a fly-wheel 23. The moment of inertia of the fly-wheel 23 is such that the momentum of the wheel is large as compared with the friction of the bearings; this ensures that the speed of the gear-wheel 21 is maintained sufficiently to ensure that only the high teeth thereof contact with the teeth of the pinion, the high teeth thus becoming ground first, and other teeth gradually coming into action as the high teeth are ground down.

The oil-containing piston 10 of a garage lift is raised in a cylinder 12 by applying air under pressure to the surface of the oil in the piston through a tube 34 connected to the inlet port 36 in the cylinder base thereby causing oil to flow from the piston to the cylinder through a metering device 18 in the base 16 of the piston, and means are provided which automatically prevent further transfer of oil from the piston when the oil in the piston falls to a predetermined level above the metering device. The metering device 18 comprises a sleeve 50 mounted in the aperture 20 in the piston base 16 and provided with sealing plates 52, 54 surrounding the air tube 34. As the piston is raised, the plate 52 is pressed down on to the piston base 16 and oil passes through an annular passage 60 between the sleeve 50 and tube 34, through a passage 62 in the sleeve 50 and between the base 16 and plate 54 into the cylinder. A floating valve member 70, comprising a sleeve 76 loosely supported on the air tube 34 and provided with floats 72 closes the passage 62 when it engages the metering device 18 due to a fall in the oil level in the piston 16, thereby preventing further raising of the piston 10. A sealing ring 80 is provided on the sleeve 76 and closes the space between the sleeve and the air tube 34 when the sleeve seats on the plate 54. The cylinder is provided with a stop 46 to engage a flange 44 on the base of the piston U.S.A. Specification 2,763,128 is referred to.
