Title: Improvements in change speed gears and friction clutches
IPC: F16H3/08
Filed: 1921-08-10
Abstract: 188,087. Bradshaw, G. Aug. 10, 1921. No Patent granted (Sealing fee not paid). Facilitating changing speed. - Variable-speed gearing comprising a driving-member 302, Fig. 2, an intermediate member 304, and a driven member 308 has an arresting-clutch arranged between the intermediate and driven members to facilitate speed change. The members 302, 304 may be driving and driven members of the main clutch of a motor-vehicle and 308 the shaft driven through a countershaft 311 or through a clutch 317. The arresting-clutch is in the form of a conical collar 327 on the shaft 308, which is slid to the left so that thrust is transmitted to the member 304 to disengage it from the member 302. Action between the collar 327 and clutch pinion 306 tends to bring the member 304, the countershaft and the shaft 308 to similar speeds. In this arrangement, a service brake 321 may be applied by the continued sliding movement of the shaft 308. In a construction shown in Fig. 1, the main clutch 9 is of the multiple-disc type. When the clutch is disengaged, a dise 16 turning with the intermediate member 21 is thrust against a clutch disc 29 secured to the driven shaft 22.

Filed: 1927-08-22
Abstract: 288,474. Polanyi, M., and Bogdandy, S. von. Aug. 22, 1927. Condensers.-Apparatus for producing a body suitable for an insulator or condenser, and consisting of several superposed thin metallic and insulating layers in alternation, comprises spaced apart nozzles or the like, and the materials constituting the layers are delivered alternately in the form of a vapour or liquid in rapid succession, and condensed on a common cooled surface, the thickness of individual layers being determined by the number of alternations, and the quantity of material delivered, in unit time. Non-conducting material is sprayed from nozzles d, e, and conducting material from nozzles f, g, on to a rapidly rotating drum c which is constrained against axial movement by a collar k. A conduit m in the hollow shaft admits cooling medium, for instance the vapour of liquid air, which escapes from the other end of the shaft, a valve o and holes p controlling the amount of flow. By means of a tube s a vacuum is maintained in the casing. The nozzle openings are splayed as shown at the nozzle e in Fig. 2, and where an insulator is desired, the nozzles are all in alignment. When, however, a condenser is desired, the nozzles f, g are placed on either side (Fig. 2) of the nozzles d, e, so that the metal surfaces deposited extend alternately at either end beyond the, insulating surface and are therefore in connection with one another to form the two poles of the condenser. The drum is arrested when the required number of layers is deposited and the layers are stripped from the drum.

Fig. 3 shows an arrangement for a key-operated ignition switch, in which a key 23 is used to give a partial rotation to an element 17 of the switch, this element being connected to a spindle 19 which carries a pin 21 engaging a helical groove in a cup-shaped member 16 prevented from rotary movement by a pin 18 sliding in a groove in the casing 15. When the switch is turned on, the member 16 is moved axially so as to give a pull to a Bowden wire 25 which moves the throttle to the idling position. Instead of the pin and helical groove, the spindle may be formed with a face cam which actuates a lever connected to the Bowden wire, or the throttle may be moved by a solenoid controlled by the ignition switch.

[Class 4.] In aircraft provided with sustaining parachutes means are provided for pulling in the parachute cable thereby causing the parachute rapidly to approach the craft in order to retard the fall of the latter, just prior to alighting. A parachute 1, Fig. 1, is connected by a cable 2, passing through an elevated guide member 4 disposed vertically above the centre of gravity of the craft, to a winch 7 in the fuselage. Winch 7 may be driven by the propelling engine or by a separate engine and is provided with a brake 8. In a modification, Fig. 2, cable 2 is connected to a piston 8<1> slidable in a cylinder 9.
