Abstract: 803,883. Mounting motors. ENGLISH ELECTRIC CO., Ltd. Aug. 19, 1955 [Aug. 20, 1954], No. 24264/54. Class 35. [Also in Group XXXI] The mounting of an electric tractor motor 10 comprises suspension bearings 15, 15 between the vehicle axle 12 and a tubular housing 16, a plurality of rubber rings 23 encircling and spaced along the housing 16, and resiliently mounting the latter in a seating 26 rigid with the motor frame 10, the radial clearance between the housing 16 and the seating 26 being such as to allow limited relative radial and tilting movement of the housing 16 and the motor 10, and separate resilient means 32 interconnecting the housing 16 and the motor 10 for resiliently restraining relative transverse movement of the housing 16 and the motor 10. The resilient means 32 comprise rubber blocks prestressed in compression between a bracket 31 rigid with the housing 16 and a U-shaped bracket 30 rigid with the motor 10. The seating 26 comprises a semicircular part formed integral with the frame of the motor 10 and two semicircular caps 27. The rubber rings 23 are bonded to inner and outer metal tubes 24 and 25, each unit 23, 24, 25 being split diametrically. Insulating sleeves 29, 29 prevent metal-to-metal contact between the housing 16 and the seating 26. A circuit to earth which does not include the bearings 15, is provided by a brush 33 mounted in an insulated brush box 34. The drive from the motor 10 to the axle 12 is by means of a pinion 13 of the motor shaft meshing with a gear wheel 14 carried by the axle 12. The flanks of each tooth of the pinion 13 are tapered so that relative tilting movement of the housing 16 and the motor 10 cannot result in a concentration of tooth loading at the end of the teeth. In a modification (Fig. 3, not shown), a second assembly of brackets 30, 31, and rubber blocks 32, are mounted above, as well as below, the axle 12. Specifications 561,714, [Group XXIV], 701,978 and 735,587, [Group XXXI], are referred to in the Provisional Specification.

Patent GB-406061-A (GB)
Title: Improvements in or relating to controlling devices for automatic clutches for motor vehicles
IPC: B60K23/02
Filed: 1932-09-01
Abstract: 406,061. Operating clutches. KNORR BREMSE AKT.-GES., 9, Neue Bahnhofstrasse, Lichtenberg, Berlin. Sept. 1, 1932, No. 24404. Convention date, Nov. 13, 1931. [Class 80 (ii).] Relates to an automatic clutch-operating device of the kind set out in Specification 371,923, [Group XXXI], in which the clutch is operated either by means mounted on the gear lever, or by a device dependent on the speed of the motor, which device is put out of action when the accelerator pedal is operated. According to the invention, an electric switch on the gear lever is arranged in series with a switch on the accelerator pedal so that operation of the gear lever switch cannot close the circuit of the clutch-operating device except when the accelerator pedal is released. In the form shown in the Fig., the clutch-pedal 4 is operated by a vacuum cylinder 1, which is connected to the induction pipe 7 or to atmosphere according to the position of a valve 8 operated by an electromagnet 10. When the accelerator pedal 14 is released, and the engine idling, the parts are in the position shown, the clutch being disengaged. The circuit of the electromagnet 10 is made from the battery 12 through the electromagnet 10, switch 15 on the accelerator pedal, and thence to earth, either through the switch 17, or through the switch 26 on the knob of the gear lever 27. When the accelerator pedal is depressed, the circuit is broken and the clutch is engaged. When the speed of the vehicle exceeds a certain amount, the dynamo 23 supplies sufficient current to the electromagnet 19 to attract the armature 18 and open the switch 17. Hence the clutch is not disengaged, even when the throttle is closed, until the speed of the vehicle has fallen below the above-mentioned amount. In changing gear, the clutch is only disengaged when the gearlever switch 26 is closed, by holding the knob of the lever, and at the same time the accelerator pedal 14 is released. Hence, on momentarily depressing the pedal for " double-declutching " the clutch is momentarily re-engaged. Specifications 353,636; and 372,553, [Group XXXI], also are referred to. In the Specification as open to inspection under Sect. 91, Specification 240,522, [Class 79 (v), Motor vehicles, steering &c.], is referred to. This reference does not appear in the Specification as accepted.

Abstract: 1,260,558. Supplying and collecting bobbins to and from machines. PALITEX PROJECT CO. G.m.b.H. 19 May, 1969 [20 May, 1968; 13 Sept., 1968], No. 25373/69. Addition to 1,180,108. Heading D1F. In a modification of the two-for-one twisting machine of the parent Specification, the endless conveyor capable of being driven continuously or intermittently at different speeds is located above the winding section instead of below the spindle section, thus enabling all transport movements to be effected at the same level with consequent saving in space on and between machines. Optionally, the machine is further provided with a rising endless conveyor capable of being driven at the same speed as the upper conveyor and equipped with bobbin receivers: it may be fitted in a mobile frame whereby it is detachable from each of several machines it serves. In operation, when a bin containing bobbins corresponding in number to the machine spindles is positioned in front of the head of the machine (or such bobbins are ready on a table) and the two conveyors are running, the bobbins are inserted continuously in the bobbin receivers and are transported to a point, slightly above the level of the upper conveyor, whereat the rising conveyor moves parallel to the other conveyor across a number of spindles (until it returns downwards) and on this section bobbins are gradually transferred by an angled contact bar to bobbin receivers on the upper conveyor whereby they are distributed around the machine above the winding components. The conveyors are stopped to enable individual delivery bobbins to be donned on the spindles and empty sleeves to be inserted in the bobbin creels of the winders, preparatory to spinning. When the winding bobbins are full, they are transferred to bobbin receivers of the upper conveyor which then transports them towards the loading end of the machine whereat they are detached by a second contact bar to fall down a chute whereby, with their speed reduced by a baffle, they are deposited in a storage bin. The upper conveyor may distribute empty sleeves from sleeve containers below its bobbin receivers. Automatic counting mechanisms may record and limit the number of delivery bobbins taken to the upper endless conveyor and record the number of winding bobbins moving down the chute.
