Patent GB-881014-A (GB)
Title: Machine to deposit or feed articles into containers
IPC: B65B61/20
Filed: 1959-02-13
Abstract: 881,014. Endless conveyers; shoots. HEDLEY & CO. Ltd., THOMAS. Feb. 13, 1959 [Feb. 14, 1958], No. 5139/59. Class 78 (1). [Also in Group XVII] A plurality of receptacles 5, on an endless chain 4, are temporarily halted beneath shoots 1, 2 from which each receptacle 5 receives one or more articles, the receptacles being then caused to move over and in unison with a plurality of continuously moving containers C into which the contents of the receptacles are discharged. The machine is adapted to deposit " gifts " in breakfast cereal packets. Conveyer.-The chain 4 passes over a pair of upper sprockets 21, 22 and a pair of lower sprockets 16, 17, the sprocket 16 being driven in synchronism with the continuously moving containers C. Acting on the outer periphery of the chain 4 is an intermediate pair of sprockets 9, 10 mounted on arms 6, 7 interconnected by a link 11. The arms 6, 7 are pivotally mounted at their lower ends and are adapted to be oscillated in timed relationship with the moving containers C such that the instantaneous length of chain between the upper sprockets is moved intermittently to provide stationary periods, whilst the lower sprockets continuously move the chain therebetween at a constant speed. Each receptacle 5 on the conveyer comprises a bucket having hinged covers that are open, whilst the bucket passes between the upper sprockets 21, 22 to permit the shoots 1, 2 to deliver the article or articles therein. On leaving the shoots 1, 2, the covers close. After passing around the sprocket 17 each bucket becomes inverted and trip means causes the bucket covers to open so that the contents are transferred into a corresponding container, the transfer being assisted by drawing the bucket through serrated guides to vibrate it. Shoots.-The shoots consist of 16 stainlesssteel boxes 2 open on top and closed at the bottom 1 by automatically activated lids. The lids are operated, in groups of two, by 8 connecting rods 50, Fig. 2, fitted with shock absorbers, in turn driven by 8 arms 51 on a shaft 52. The shaft 52 is oscillated by camoperated means 58, 56, 55, 54, 53. The camoperated means also ensures that the buckets 5 are positioned exactly beneath the shoots 1, 2, during the time the upper part of the chain 4 is motionless. This is achieved by the force necessary to cause the cam follower 56 to leave the cam socket 58, said force counteracting the forces of inertia during the cessation of motion to cause the upper part of the chain to stop in the same position each time.

Title: Improvements in or relating to pumps
IPC: F04D17/16
Filed: 1938-02-23
Abstract: 511,782. Rotary compressors. BOSCH GES., R., (formerly BOSCH AKT.-GES., R.). Feb. 23, 1938, No. 5660. Convention date, Feb. 23, 1937. [Class 110 (ii)] [Also in Groups XXVIII and XXIX] A compressor 2 maintains a pre-determined vacuum in a container 5, through mechanism 8-18 which closes a throttle valve 8 in the normal inlet 7 to the compressor when the vacuum in the container is reduced. A pipe 6 leads to places where a vacuum is required to be maintained, e.g. in a motor vehicle brake system. The vacuum holds a piston 21 in its low position, against the pressure of a spring 24, and the throttle 8 is held open, and a non- return valve 4 in a pipe 3 is closed. Air enters the compressor 2 from the atmosphere through a filter 9. When the vacuum in 5 is partly lost, the piston 21 rises and a lever 18 is turned to cause a spring-pressed roller 15 to ride over a curve 13 on the lever 12, into a socket 14. The valve 8 is thus closed, and the compressor sucks air through the valve 4 until the vacuum in 5 again causes the piston 21 to move downwards and open the valve 8. Fig. 4 shows another arrangement in which atmospheric air is normally sucked through a port 27 leading from the pipe 1, and a valve 30 normally closes the pipe 3 leading to the container. A valve 37, fixed on a flexible diaphragm 38, is kept raised from its seat 36 when adequate vacuum is held in the container 5 and pipe 23, and air is sucked into the compressor through a filter and passages 34, 35, 27. Valve 30 is closed. If the vacuum in 5 decreases, a spring 41 presses the valve 37 on to its seat to close the channel 34 from the compressor. The valve 30 then lifts and the compressor suction acts through pipes 29, 3, leading from the container. The tension of springs 24, 41, may be adjusted. The invention may be applied to a plant in which compressed air may be supplied to a container by a vacuum pump normally pumping to atmosphere, to maintain a required pressure in the container.

Abstract: 1493621 Fishing reels H POLICANSKY 5 Feb 1975 [7 Feb 1974] 05762/74 Addition to 1333432 Heading A1A In a fishing reel of the multiplying type a spool 1, rotatably mounted on a shaft 2 supported between end housings 3, 4 moulded from a thermoset plastic, is turned by a winding handle 38 through gears 40, 43 and a friction coupling comprising a disc 44 engaging a ring 45 fixed to the gear wheel 43 and the spool 1 respectively. To adjust the friction coupling the shaft 2 is rotated by a lever 34 to screw it into or out of a nut 13 rotatably mounted in the end housing 3. The lever 34 is secured to the shaft 2 by screws 32 which pass through the lever 34 and a disc 33 into a bush part 27. The lever 34 is held in the set position by friction pads 35 urged into engagement with the disc 33 by springs 36. The nut 13 may be rotated by turning knob 20 of spindle 19, which rotates a pinion 18 whose gear teeth mesh with those around the circumference of the nut 13 to adjust the relative position of shaft 2 and thus change the range over which the lever 34 affects the frictional coupling. The winding handle 38 is prevented from turning in the unwinding direction by the ratchet and pawl arrangement of Figure 2 which comprises a ratchet wheel 48 secured to the gear 43 and a pawl 49 pivotally mounted in a recess 50 in the end housing 4. A second recess 55 is provided in the end housing 4 to enable the pawl to be mounted such that the direction of rotation of the disc 44 can be reversed. To provide a very small drag on the spool when the friction coupling is disengaged for casting a film of oil supplied through a wick from a reservoir formed by a bore 57 in the shaft 2, is maintained between the bearing surfaces of the shaft 2 and the spool 1.

Abstract: 739,653. Electrically - tripped switches. ARROW ELECTRIC SWITCHES, Ltd. March 3, 1954 [March 20, 1953], No. 6194/54. Class 38 (5). In order to prevent damage to control circuit contacts 42, 46 due to burning out of the main-current carrying heaters 17 of overload bimetals 20, the latter are mounted in recesses 10a-10c on one side of the base 10, and the contacts 42, 46 on the other, an insulating spring - biased rocker 30 forming part of the overload release mechanism also being pivoted on this side by a pin 31. Contact 42 is carried by a resilient blade 40 secured between base 10 and a terminal bar 44, and in the closed position of the switch (Fig. 3) the end of the strip engages face 36 of an extension 34 of rocker 30. On overload, one or more of the bimetals 20 flex and by their engagement with projections, such as 33b, cause the rocker to pivot, thus releasing the blade 40 and breaking the circuit. Engagement of the end of blade 40 with surface 37 of extension 34 prevents the rocker from returning to its previous position, until the switch is reset by pressing a button 50 which restores blade 40 to closed position. Metal plates 18 shield the bimetals from the heaters. The invention may also be applied to contacts which are normally open and close on heating of the bimetals. The position of the free end of each bimetal 20 may be adjusted by turning screw 24 which bears on a pivoted lever itself bearing on the bimetal 20.
