IPC: F02B75/04
Filed: 1930-07-07
Abstract: 358,553. Balancing moving parts. PACKARD MOTOR CAR CO., Detroit, Michigan, U.S.A. July 7, 1930, No. 20503. Convention date, Oct. 10, 1929. [Class 122 (iii).] The compression ratio is varied automatically and inversely to the load by an eccentric sleeve 33 mounted on the crank pin; the big-end 30 of the connecting-rod takes over the eccentric, which is held up by a spring 43 tending to keep the compression ratio at its maximum value corresponding to a certain minimum load. As shown, the device is applied to a radial cylinder aeroplane engine driving a propeller 20. The spring 43 is housed within a hollow in the crank shaft and bears on a sleeve threaded internally and feather-keyed to the crank shaft; a threaded rod 36 engages the sleeve and carries at its inner end a pinion 37 to engage with teeth 35 formed on a flange 34 on the eccentric. A balance weight 50 is attached to the sleeve to compensate for the eccentric mounting of the connecting-rod big-end. As the load on the engine increases the sleeve is moved around the crank pin in opposition to the pressure of the spring 43 to lessen the piston stroke. The spring absorbs shocks in the working.

Abstract: 762,427. Conveyers. FAIREST, Ltd., M. July 14, 1955 [July 21, 1954], No. 21208/54. Class 78 (1). In a device for spacing upright articles, e.g. bottles 12 to be fed to a labelling head, on a horizontal conveyer 11, and comprising a worm 13 having a helical thread of increasing pitch in the forward direction and a guide rail 30 between which the articles pass, the worm and guide rail are mounted for simultaneous adjustment towards and away from one another to suit different sizes of articles, whereby the arcs of the articles always lie on the same longitudinal line of the conveyer. The worm 13 is journalled in a housing 27 carried by a lever bracket 28 pivoted on a longitudinal shaft 29 parallel with and below the conveyer and the rail 30 is carried on a similar lever bracket 31 pivoted on a longitudinal shaft 32 at the same level as shaft 29. The worm is driven from shaft 29 via an intermediate shaft (not shown) by chain gearing which includes a sprocket which is rotationally adjustable to synchronize the worm with the labelling head, which is as described in Specification 746,506, [Group XV]. The simultaneous adjustment is effected by rotation of a sleeve 36 carried by a yoke 33 journalled on lever bracket 28 by a handwheel 45, the sleeve having a first threaded engagement with a nut member 41 prevented from transverse movement by a channelled member 43 and having a second threaded engagement, at twice the pitch of the first threaded engagement, with a rod 38 pivoted at 39 to the lever bracket 31. The rail 30 carries feelers 77, 78 controlling switches 75, 76 for controlling the supply of two kinds of label to each bottle in the labelling machine. Rail 30 also carries a safety gate 58 which gives under pressure of a spring-loaded plunger 62 if a bottle fouls the rib of the worm. To ensure that the face of gate 58 is always vertical, it is carried on a vertical pivot 61 in turn carried on a bracket 63 pivoted on a longitudinal pin 64 secured to the rail bracket 31, and an extension 65 of bracket 63 is connected by a link 66 to a bracket 67 at the level of shaft 32, so that lever bracket 31 and link 66 together form a pair of parallel links. A lead-in member 73 is pivoted at 70 to one of the guide rails 69 at the sides of the conveyer and has a pin and slot connection 71, 72 with the rail bracket 31. Alternatively, a combined safety gate and leadin member 79, Fig. 7, may be pivoted at 80 to the guide rail 69 and carry a roller 81 urged against the end of the rail 30 by a spring 83 so that the member 79 gives when a bottle fouls the rib of the worm.
