Patent GB-172050-A (GB)
Abstract: 172,050. Moss, G. L. June 29, 1920. Switches, without spring action; covers; handles.-Relates to means for igniting the lamps of motor-vehicles by diverting current from the high tension system of the engine to spark gaps at the lamp burners and comprises a switch device mounted on the sparking-plug of the engine or other point of the high-tension system, the switch being completely covered by insulating material which serves as a shield to the head of the sparking-plug or other electrified point of support. In the form shown in Fig. 1, the insulating cover i is mounted upon the main ignition cable g<2> conveying current to the plug g. A branch cable e leading to the spark gap at the lamp burner is connected bv means of a screw i<3> to a spring i<2> one end of which is attached to a sleeve i<1> on the main cable g<2>, whilst the other end extends along the internal surface of the cover to a point over the central electrode g<1> of the plug. On depression of the cover i, the spring i<2> contacts with the central electrode g<1> and current is diverted to the spark gap at the lamp burner in which one of the electrodes is earthed. Fig. 2 shows a switch for selectively controlling the supply of current to a number of lamps to be ignited. It comprises an inverted cup-shaped base of insulating material secured to the central electrode g' of the sparking-plug by means of the usual terminal screw for attaching the main igniting cable g<2>. Rotatably mounted upon the base j is an insulating cover j<2> to which are attached the branch cables e leading to the spark gaps of the various burners to be ignited. The branch cables e are in electrical connection with spring-pressed balls j<3> which, on rotation of the cover, are in turn brought into contact with a radial distributing arm j<1> embedded in the base j and in contact with the central electrode of the plug. The positioning of the cover j<2> in relation to the base j is determined by the check action of a spring-influenced locating-ball j<4> which is adapted to engage depressions formed in the periphery of the base as shown in Fig. 4. The spring-pressed balls also serve to retain the cover j<2> in place upon the base by engaging a circumferential groove in the latter. In a modified form of selective switch, the contact balls for the branch wires are housed on the fixed base portion of the switch, and the distributing contact is carried by the rotary cover, connection with the plug being made by a spring bearing upon the top of the central electrode.

June 12, 1935, No. 17323/34. [Class 138 (i)] [See also Group XXVI] A windscreen-cleaner operated by liquid under pressure, as for example from the lubricating system of a vehicle, is provided with a pair of valves on a common spindle, each valve being reciprocable between spaced valve seatings of different bore formed in a valve housing located between the heads of a double-acting piston which is connected to the wiper and is reciprocable within a cylinder. In the construction shown in Fig. 1, piston heads 10 are connected by a rack 11 engaging a pin 12 carried by the spindle 13 of a windscreen wiper, the spindle 13 being oscillated on movement of the piston heads within a cylinder 14. Oil under pressure is fed through a valve-controlled inlet 15 and is directed to chamber 20 or 21 according to the position of valves 18, 19 in a valve chamber 16. The valves are carried by a slidable spindle 19 on a sleeve 26, the bore of which is of smaller cross-section than that of either of valve seatings 27, 28. With the valves in the position shown, oil flows from pipe 15 through conduits 22, 23 to the chamber 20 and causes the piston heads to move towards the left. Oil in the chamber 21 is forced out through conduits 25, 24, and apertures 31 to the space between the piston heads, this space communicating with an outlet leading to the oil sump. The movement of the piston heads continues until a spring-mounted plunger 32 engages the valve spindle 19 whereby the valves are operated to change the direction of oil flow and produce reversal of movement. A spring 35 is provided for operating the valves at the end of this second movement. In the construction shown in Figs. 3 and 4, the valve mechanism travels with the piston heads. The oil inlet 37 communicates with conduits 39, and the outlet 40 with conduit 41. Springs 42 are provided to cause operation of the valve mechanism at the end of each traverse of the piston heads.
