Lift cages and doors, locking and unlocking. - Relates to means for preventing the opening of a well door unless the cage is in the correct position and for preventing starting of the cage unless the well door is closed. The well door a, Fig. 2, carries a stud a' adapted to engage, in the final closing movement of the door, a forked lever b pivoted to a bracket b<1> on the well opening. A bent lever c<1> is pivoted on the lever b, its long arm c being adapted to engage a projection b<3> on the bracket. The other arm of the bent lever is connected by a link d to a second bent lever e which engages one arm of a third bent lever f, the vertical arm f<2> of which carries a roller f<3> which is adapted to be projected towards the car g by a spring f<4> and by the opening of the well door. The door is normally locked by the engagement of the stud a<1> with the forked lever b and the engagement of the arm c with the projection b<3>. To disengage the arm c it is necessary that resistance is offered to the movement of the lever f<2> so that the lever b can swing over to the disengaging position, Fig. 5. This resistance is offered by an appliance on the cage when it is in position at the well door. The resistance appliance comprises a shoe h on a sliding bar h' mounted in guides h<2> on the cage. A second sliding bar k is mounted in guides b<3> on the bar h<1> and is connected by a toggle i and linkage i<4> to bent levers i<5>, i<7> Fig. 1, the lever i<7> being weighted to normally hold the toggle extended, so that the shoe offers the required resistance to the roller f<3>. When the lever c has been disengaged and the door opened, the roller f<3> is projected to engage the shoe and through linkage o, o<2> opens a switch p<1> in the control circuit arranged to cut off the power from the motor, whether the controller s is in the starting position or not. The weighted lever i<7> is connected to the core of a solenoid l' arranged in the motor control circuit, so that when the motor is energized, the solenoid is energized, the weighted lever is raised to break the toggle and withdraw the shoe, and vice versa when the solenoid is de-energized the toggle is straightened and the shoe projected. In a modification, the solenoid is replaced by a stalled motor carrying a pinion engaging with a segmental rack linked to the toggle mechanism.

The source of pulses comprises a multi-vibrator VT1, VT2 which when K1 is operated sends a pulse every “ m.sec. to the counting chain which comprises cold cathode gas-filled discharge tubes VK3 ... VK17, VK1 which are fired in succession and are arranged in groups which are extinguished when the first tube in the next group is fired. At the appropriate points in the chain the tubes are connected to a binary counting chain VK18 ... Each stage of the binary chain comprises the tubes VK18, VK19, VK20, the first VK18 of which is initially conducting so that the first impulse applied to the trigger electrodes of the tubes VK19, VK20 fires the tube VK20 and the tube VK18 is thereby extinguished. The next pulse applied to the trigger electrodes of tubes VK19, VK20 fires tube VK19 and tube VK20 is extinguished. The tube VN16 then fires to send a pulse to the second stage of the binary chain. Each pulse delivered to a binary stage reverses the state of tubes VK19, VK20 of that stage. As the chains build up a discharge lamp indicator VN1 ... VN1H is operated to agree. At the end of the timing the multivibrator VT1, VT2 is stopped oscillating and the display on the indicating tubes shows the duration of the " event." Operation of a key K2 extinguishes all the conducting tubes.

Title: Dual amplitude vibration generator
IPC: E01C19/28
Filed: 1972-02-28
Abstract: 1327002 Vibrators VIBRO-VERKEN AB 25 Feb 1972 [4 March 1971] 8843/72 Heading F2X [Also in Division B7] A dual amplitude vibrator has a pair of eccentric weights 12, 14 mounted on a shaft 10 in such a way that a different amplitude of vibration is obtained simply by reversing the rotation of the weights. The weight 12 is attached to the shaft and is rotatable with it, while the weight 14 is mounted on the shaft but is freely rotatable relative to it. Each weight 12, 14 has a pair of contact surfaces (20, 22 and 20<SP>1</SP>, 22<SP>1</SP> respectively) that co-operate with similar surfaces on the other weight, so that when the shaft 10 is rotated in a clockwise direction the surface 20 on the fixed weight 12 engages the surface 20<SP>1</SP> on the free weight 14, resulting in both weights revolving as a single composite eccentric weight as shown in Fig. 1. When the shaft 10 is rotated in an anticlockwise direction, the surfaces 22, 22<SP>1</SP> engage one another, as shown in Fig. 2, resulting in the formation of a composite weight with a centre of gravity nearer the shaft 10 and thereby generating vibrations of lower amplitude. The invention is described with particular reference to its application to the roller of a vibratory road compactor (Fig. 4, not shown). Two pairs of eccentric weights are mounted at opposite ends of the roller, each on a shaft section which is journalled in the roller by means of bearings positioned in outer and inner bearing housings. Each of the inner bearing housings forms a part of an oil reservoir which is integral with a side wall of the roller and projects inwardly from it, the reservoir containing oil for "oil bath" lubrication of the bearings. The shaft sections are joined by a drive shaft and driven by a reversible hydraulic motor.
