Title: Improvement relating to the starting handles of internal combustion engines
IPC: F01L13/00
Filed: 1934-08-24
Abstract: 435,952. Turning-gear. BARBAGLI, F., Iona, South Woodham Ferrers, Chelmsford. Aug. 24, 1934, No. 24385. [Class 7 (v)] In a device for disengaging a starting handle or an electric starter if the engine shaft turns in the reverse direction, the clutch jaws on the starter shaft engage spring-controlled arms 4 pivoted on a plate 3 mounted on the engine crank-shaft or equivalent shaft 1 with freedom for unidirectional rotation, and a member 2 fixed on the shaft 1 is arranged to disengage the arms 4 from the clutch jaws on reversal of the engine shaft. In the form shown, the tubular shaft 1 has a slotted front end for engagement with the engine crank-shaft, and the plate 3 carries pivoted pawls 8 engaging a ratchet wheel 9 integral with a disc 10 secured at 11 to a fixed part of the engine. The arms 4 are held by springs 6 in the position shown in Fig. 1, a boss on each arm 4 having a radial face 5 in engagement with a tooth of the ratchet wheel 2 fixed on the shaft 1. At starting, the hub 15 of the starting-handle 14 is slipped over the shaft 1 so that the clutch jaws engage the arms 4. If the engine backfires on starting, the arms 4 are moved out of engagement with the clutch jaws of the starting handle by the engagement of the ratchet wheel 2 with the radial faces 5 on the arms 4. In a modification, the disc 10 is counterweighted, to keep it substantially stationary, instead of being fixed, and the device may be removable and portable. In the case of an electric starter, the tubular shaft 1 is mounted on the end of the starter shaft carrying a pinion for engagement with the engine flywheel, the disc 10 being fixedly connected to the starting motor and the starter shaft being fitted with a socket such as 15 for engagement with the arms 4.

Class 110(3) [Also in Groups XXV and XXXIII] An arrangement for supporting an aircraft engine in an aircraft comprises a trunnion mounting including a stub shaft fixed to the aircraft and extending towards the engine substantially at right angles to the engine axis, and a bearing on the engine casing to be engaged by the stub shaft and to permit angular movement of the engine about the shaft axis and about an axis at right angles to both the engine axis and the stub shaft, which axis is substantially contained in the wall of the engine casing. Referring to Figs. 1 and 2, the engine is a turbo jet, and comprises box struts 17 radially connecting the members 14 and 18 respectively supporting the inner and outer ends of the turbine stator blades. Preferably two bearings receive two stub shafts diametrically opposite and aligned, and each in line with a box strut 17.

Abstract: 465,592. Charging batteries ; heating water by electricity. CALDWELL, P. G. Oct. 13, 1936, No. 25450/35. [Class 38 (iv)] [Also in Groups XI, XXVIII, and XXXVI] In a system for charging the battery of a motor vehicle and heating the cooling water from A.C. or D.C. mains using a rectifier as required, the supply plug is interlocked with a switch so as to cut off the battery from the vehicle circuits. The heater resistance is so tapped that the heating and charging rates may be changed for operation on either the higher (200) or lower (100) voltage ranges. The switch arm y is spring biassed so as normally to cover the plug socket b2, the battery terminals x<4>, x<5> being then connected to poles x<1>, x<2> leading to the car dynamo, lights &c. ; but when the mains plug is inserted into socket b; the switch arm is moved to break this connection. Current is supplied from socket terminals b4, b4 to some or all of the heater windings o in series with the rectifier C and the battery B. Connections may be made to the heater terminals q, r, s, t, u in several ways according to whether the mains voltage is in the neighbourhood of 100 or 200 volts ; also to give full or half charging rates. The heating element consists of resistance wire wound on a sheet of mica or embedded in manganese oxide, magnesium oxide, fireclay, or other insulating material, the whole being enclosed in a metal tube secured in position by a dished flange p which is clamped between the end of the main casing j and the terminal cover. A deflecting plate l of high conductivity metal is disposed above the horizontal heater element so that water can only pass upwards beyond the ends of the plate to an outlet m towards the centre of the plate. The pipes attached to the inlet i and outlet m are connected to the usual radiator hose by cutting a hole in the hose and clamping the wall of the hose between inner and outer dished washers d, e on the ends of the connection. A switch s allows operation of the heater without charging of the battery. Specification 344,911 is referred to.
