Title: Actuating Apparatus for Swivel Windows of Motor and Other Vehicles
IPC: B60J1/14
Filed: 1968-02-16
Abstract: 1,187,351. Swivel window mechanisms. DAIMLER BENZ A.G. 16 Feb., 1968 [18 Feb., 1967], No. 7727/68. Heading E2M. An actuating apparatus for a swivel window of a vehicle, in which the window is capable of being swivelled by a rotary element actuated from the interior of the vehicle and connected to the swivel window through a self-locking step-up gear, is characterised in that the stepup gear provides a definite association, as regards angle of rotation, between the position of the rotary element and the position of the window only within a limited angular displacement of the window from its closed position; outside this range, the window is connected to the rotary element through a slip coupling or catch coupling whose power is such that it may be overcome manually. In the embodiment shown in Figs. 1 and 2, the step-up gear comprises a worm 14, a first pinion 42 connected integrally to an axle stub 26 and having only two teeth 44, 46, and a second pinion 50 which has teeth all round and is permanently in mesh with the worm 14. Two plate springs 52 are positioned on an axle stub 48 and abut the bottom end face 54 of the pinion 50 and a cotter 56. The slip coupling is constituted by the abutting faces 58, 60 of the pinions 42, 50. Rotating the handwheel 20 causes the teeth 44, 46 of the first pinion 42 to rotate the axle 26 and window. 34. When the handwheel 20 is rotated further, the teeth 44, 46 move out of engagement with the worm 14 and from this position onwards the window 34 may be rotated by gripping it directly since the slip coupling allows movement of the first pinion 42 with respect to the second pinion 50. Fine adjustment by rotating the handwheel still remains possible because the second pinion 50 is permanently in engagment with the worm 14. The slip coupling may be replaced by a catch coupling in which one of the pinions contains a bore out of which a locking element, preferably a ball, can be partially urged and into depressions e.g. the tooth gaps, in the end face of the other pinion. In a modification, Figs. 5 and 6 (not shown) a single pinion (76) having at its top end face a cam surface (80) cooperating with a cam surface (82) on the housing 10, is slidably mounted on a bearing axis (84) and is connected to said bearing axis by a slip coupling. The bearing axis possesses a lug (86) which extends into a recess (88) in the pinion, thus giving a positive connection between the pinion and bearing axis (84). After rotation of the pinion beyond a given angle, the cam surface (80) strikes against cam surface (82) forcing the pinion down against the action of a spring (98) so that the positive connection between the lug (86) and recess (88) is cancelled and the axle (26) becomes capable of free rotation.

Abstract: 762,213. Rotor driving arrangements. MAXWELL ETABLISSEMENT. March 18, 1954, No. 7845/54. Class 35. A centrifuge or a mixer may be separately attached to and driven by a motor adapted to run at two speeds, the arrangement being that the centrifuge is driven only at the lower speed and the mixer is driven at either speed. With the centrifuge 2 attached the motor circuit comprises a switch 6, a centrifugal governor 8 and a motor 9 so that with the switch set to position P the motor is held at the lower speed by the governor, and with the switch set to position M the motor circuit is broken. On attachment of the mixer its casing depresses a pin 14 to close a switch 12 so that with the switch 6 set at the position M the governor is shorted and the motor runs at the higher speed, and with the switch 6 set at the position P the governor is operative to limit the speed. If neither the centrifuge or mixer are attached and the switch 6 is set to the position P, the motor runs at the lower speed. An additional switch actuated by the attachment of the centrifuge or the mixer may be fitted in the circuit so that the motor will run only when the centrifuge or mixer is attached. In a modification the attachment of the mixer or centrifuge acts directly on a switch controlling the motor speed.

[Class 38 (i)] When a fuse blows, an ignitible material associated with the fuse produces power, which is used either to associate another fuse carrier with the circuit or to draw a new length of fuse wire into position. As shown in Figs. 1 and 3, the fuse wire F is wound about an ignitible material C, such as a cotton treated with nitro-glycerine. Alternatively the wire may be coated with a readily ignitible material or a tube of ignitible composition may carry a conductive coating which acts as a fuse. When the fuse blows the material burns and the gases produced drive the piston P against the action of spring R. The contact N is moved out of the path of the spring or weight driven contact-arm K which rotates to engage the contact N of the next fuse carrier. The shaft T may be threaded so that the contact N is given a rotary movement. When the piston has risen, the part Q is uncovered to allow the gases to escape and the piston is then restored by spring R. The screw t enables the length of fuse wire and the capacity of the cylinder A to be adjusted. In an alternative construction the contact K is fixed and the fuse-carriers are rotatably mounted on an axis as indicated in Fig. 6. The contacts K, N may be immersed in oil for spark-quenching purposes. In the further arrangement shown in Fig. 8, the fuse wire and ignitible material are carried by the asbestos cord 36. When the fuse blows the piston 19 is moved downwards. Trigger 16 moves rod 10 upwards so that plungers 7 move to the left to release the fuse and cord while rack 24 which is carried by the piston 19 rotates drum 26 to draw a new section of fuse wire into position. When the piston has passed the trigger 16, the plungers 7 restore and clamp the fuse wire and cord whilst the gases escape through opening 17. The piston 19 is then returned by spring 22, the movement being delayed by governor 44. The latter is effective over part of the travel of piston 19 only so that the initial downward and final upward movements of the piston are rapid and give a quick make- and-break of the circuit. The capacity of the cylinder is adjusted by the insulating member 34.

Abstract: 719,136. Belt gearing. COAL INDUSTRY (PATENTS), Ltd. April 15, 1952 [April 12, 1951], No. 8547/51. Class 80 (1) [Also in Group XXX] Apparatus for automatically stopping an endless belt whenever a rate of slip above a predetermined value is persisting between the belt and its driving drum or pulley comprises a differential gear drivably connected on one input side to an idler roller or the like rotating at a speed dependent upon the belt speed and on the other input side to the belt driving drum or pulley. The differential sum of the two input speeds derived from said gear being used to actuate a trip operative to cut off power supply to the motor driving the belt driving drum or pulley. The Figures show the application to a conveyer belt wherein the bevel wheels 3, 4 of the differential gearing are driven by chain wheels 1, 2 respectively, the chain wheel 1 being connected through a chain and gearing with an idler roller and the chain wheel 2 being connected by gearing to the belt driving drum. The chain wheels 1, 2 are so arranged that the bevel wheels 3. 4 rotate in opposite directions at the same speed when the belt is slipping at a pre-determined maximum allowable rate of slip. With no belt slip, the wheel 3 rotates at a higher speed than the wheel 4 and therefore through the pinions 5, 6, the cage 7 and bevel wheel 7A will be rotated and drive a pinion 8 secured to a spindle 18 whereby gear wheels 9, 10 of a gear pump are rotated in the direction indicated by the arrows A. The arrangement of the gear wheels is such that under these conditions no oil is delivered into the pressure chamber 11. If the belt slips an amount in excess of the maximum rate allowable, the gears 9, 10 are rotated in the opposite direction and oil is delivered by the pump from a sump 12 through an aperture 20 to the pressure chamber 11. Pressure is thereby built up on a spring-loaded plunger 13 forcing it to a position where an oil port (not shown) is opened and the oil then bypassed back to the sump 12. The movement of the plunger is used to operate a switch (not shown) to cut off the power supply to the driving motor and may also be used to give a warning such as to ring a bell or light a lamp. After the pump has operated, oil bleeds from the chamber 11 through an aperture 15 in the diaphragm 16 of the pump to allow the plunger 13 to return to its normal position for re-starting the motor. The aperture 15 may be provided with a needle valve or other variable area device.
