Title: Improvements in or relating to a timer for controlling valves of an internal combustion engine
IPC: F01L9/20
Filed: 1949-11-04
Abstract: 665,801. Interrupters. ROLLINSON, E. W. (Thompson Products, Inc.). Nov. 4, 1949. No. 28273/49. Class 38 (v). [Also in Group XXVII] A device for varying the time and period of opening of electromagnetically-operated valves comprises an engine driven shaft 24, Figs. 2 and 3, carrying cams 89, 89a which operate respectively normally closed and normally open switches 47, 48 in the electromagnet circuits, which switches are carried by a plate 49 movable transversely of the shaft 24 to say the period of operation of the switches by the cams. The switches 47, 48 comprise spring- loaded arms 59, 63 pivoted on a common pivot 60 fixed to the plate 49, the contacts 61, 78, Fig. 11, of switch 47 being broken by cam rises 91 ... 94 on the cam 89, and a contact 64 on the lever 63 being closed against a contact 72 carried by a spring-loaded adjustable lever 70 by cam-rises 95 ... 98 on the cam 89a. The plate 49, Figs. 3 and 4, has guiding ribs, 53, 54 sliding in grooves in the stationary housing member 13 and is held in an eccentric cavity 52, Figs. 3 and 4, in a cap 14, angular adjustment of which by a lever 105 moves the plate 49 transversely to move the switch levers 59, 63 towards or away from the cams 89, 89a to vary the period of actuation of the switches 47, 48. The shaft 24 also carries a commutator ring 28 (shown developed in Fig. 11) comprising a conducting ring 33, with a projection 34 connected directly to a battery 106, and an insulated segment 32 connected to the battery 106 through the switch 47. Bushes 35 ... 42 are arranged in pairs in two sets in line with the segments 34, 32, each pair being associated with one valve. Each valve is opened by an electromagnet 124, connected on one side to one of the lower bushes 36, 38, 40, 42 and on the other side to earth through the switch 48, and closed by an electromagnet 125 connected to one of the upper bushes 35, 37, 39, 41. In the position shown in Fig. 11 all of the bushes 35, 37, 39, 41 engage the ring 33, whereby the electromagnets 125 are energized to hold the valves closed, the electromagnets 124 being de-energized. When rotation of the commutator brings the segments 32, 34 opposite, e.g. the bushes 39, 40, the electromagnet 125 of cylinder C is now energized through the switch 47 and the conductor 116 of the associated electromagnet 124 is connected through segment 34 to the battery 106. Hence when the switches 47, 48 are respectively opened and closed simultaneously by the cams 89, 89a, the electromagnet 125 is de-energized and electro-magnet 124 energized to open the valve of cylinder C which closes again, after a period determined by the position of the plate 49, when the cams 89, 89a allow the switches to return to their normal position. The rotatable cap 14, Fig. 3, is provided with arcuate lips 20, 21 which are slipped through cut-away portions of a lip 16 on the stationary housing 13 and on rotation engage beneath said lip to hold the cap 14 in position.

Title: Steering device for swivelling bogies of road vehicles
IPC: B62D13/04
Filed: 1929-09-23
Abstract: 340,253. Articulated vehicles. JONKHOFF, H. W., Holmdale, South Eden Park Road, Beckenham, Kent. Sept. 23, 1929, No. 28747. [Classes 79 (iii) and 79 (v).] In vehicles mounted on swivelling bogies 1 having steerable wheels 5 connected to duplicate controlling points by duplicate connections one for each direction of travel, the means provided to put one connection into action simultaneously releases the other. In the construction shown the vehicle is mounted on two bogies 1, only one of which is shown, and the steerable wheels 5 are steered by rods 6 connected to a member 8 pivoted on the bogie. The member 8 is formed with a central slot 10, and corresponding slots 15, 16 are formed in steering bars 11, 12 rotatable in the member 8. The steering bars are controlled by pins 17, 18 fixed on the main vehicle frame 3 and engaging with slots in the bars. A slidable pin member 19 can be moved along the slot 10 by cords 21 passing over rollers 22 and operated by hand means (not shown). When the pin is at one end of the slot, as shown in Fig. 1, it locks the member 8 and the bar 11 together, leaving the bar 12 free; when it is at the other end it frees the bar 11 and locks the bar 12 to the member 8. In the position shown, for movement in the direction of the arrow, movement of the bogie about its pivot 2 rocks the bar 11 and therefore the member 8, thus steering the wheels 5. The cords 21 in moving the pin 19 to lock the bar 11 to the member 8 of the front bogie simultaneously cause a similar pin to lock the bar 12 of the rear bogie to its member 8 so that the trailing wheels of the rear bogie are steered oppositely to the leading wheels of the front bogie. When the vehicle is to travel in the reverse direction, the pins 19 are moved to the opposite ends of the slots. The front steering bar 11 may be moved independently of the swinging of the bogie by means of a screw adjustment 27 for the pin 17, the screw being rotated by a hand-wheel 29 and gearing. Or, in trailer vehicles, the pin 17 may be carried by the drawbar. In a vehicle, such as a pole trailer, having the distance between the bogie pivots variable, the distance of the pin 18 controlling the rear steering bar 12 from the centre of the member 8 may be made adjustable so as to vary the leverage of the steering bar.
