Title: Improvements in or relating to front wheel drive for automotive vehicles
IPC: B60K17/30
Filed: 1937-04-19
Abstract: 494,011. Driving steering-wheels of motor vehicles. ALMA MOTOR CO. April 19, 1937, No. 11135. Convention date, April 20, 1936. [Classes 79 (ii) and 79 (v)] In a steering-wheel drive the axle housing 1 and steering swivel 9 have co-operating hemispherical ends 2, 10 interconnected by pivot pins 11, 19 the axis of which is inclined with respect to the driving or axle shaft 3 and intersects a ball 8 of the universal joint through which the shaft 3 drives the stub shaft 22, one of the said shafts 3, 22 being adjustable axially to position the centre of the ball 8 on the axis of the pivot pins and to ensure firm engagement of the shafts with the ball. In the construction shown the shaft 3 is fixed in location relatively to the axle housing 1 by a shoulder 7 bearing against a thrust bearing 5, and the shaft 22 is axially adjustable to press its end 23 against the ball 8 by means of a nut 25 screwing into a collar 24 splined on the shaft 22. This collar transmits the drive from the shaft to the wheel hub 27 by means of studs 26 securing the hub to the shaft. The hub is mounted on the steering swivel 9 by roller bearings 28, 29 adjusted by a nut 30. The universal joint is of the constant velocity type. The lower pivot pin 11 is seated in the steering swivel and has a shoulder 13 which takes the thrust due to the weight of the vehicle, this thrust being transmitted through the bearing 15. The upper pivot pin 19, with its bearing 18, is inserted after the lower pin and is secured to the steering swivel by screws 21. A steering arm 50 is secured to the upper part of the steering swivel between the pivot and the wheel. The wheel 32 and brake drum 33 are secured to the hub 27 by bolts 31. A stationary brake plate 34 is riveted at 35 to the steering swivel and is provided with an oil guard 60 to prevent oil leaking on to the braking surfaces. Oil seals are provided at 42 between the steering swivel and axle housing 1, at 37 between the hub and a drum 36 secured to the steering swivel, and at 40 between the axle shaft 3 and housing 1. Thus the entire unit is sealed against oil leakage and may be filled with lubricant.

Abstract: 418,672. Cycle-wheel locking-devices. BURTON, J., 13, Esher Road, New Ferry, Birkenhead. April 19, 1933, No. 11412. [Class 79 (iii).] A lock-casing c, clamped to the wheel fork or frame of a motor or other cycle, carries a pivoted arm f adapted to be swung between the wheel spokes, and to be automatically locked in this position, necessitating release by a key. The pivotal end of the arm is bent at right angles and seats in holes in opposite sides of the casing, removal being prevented by the formation of lugs j<1>. A spring l coiled round the stem normally retains the arm in the out of action position in which a radial bar k secured in a slot in the stem j bears against a fixed stop m. When the arm f is swung by hand to engage between the wheel spokes, a lug k<2> on the upper edge of the bar k is caught in a slot h<2> in a pivoted locking plate h held down by a spring g. The end k<1> of the bar k is bent at right angles and shaped to form wards for a key which is inserted through the keyhole e and rotated to lift the plate h.

Abstract: 712,971. Embossing. MASSON SEELEY & CO., Ltd. May 1, 1950 [April 29, 1949], No. 11465/49. Class 100 (2) A power-driven colour-transfer marking press comprises a hollow column, a lower platen and a hollow superstructure extending forwardly of the column, an upper platen assembly reciprocably mounted in the superstructure and incorporating foil-supporting, foil-feeding and foil take-up mechanism, and drive transmission means in the column and superstructure for reciprocating the upper platen assembly and actuating the foilfeeding mechanism. As shown the press comprises the column 1, the superstructure with a removable head 2, and a base platform 3. The lower platen 13 is mounted on a knee assembly 12 having locking devices 14 for securing the assembly to the press or removing it therefrom, in the latter case the platform 3 supporting the work. The knee assembly is adjustable vertically on the press, fine adjustments being made by a hand wheel 15 and the platen 13 is slidable toward or away from the column by a control wheel 18 and is adjustable laterally by a knob 20. The upper platen assembly 4 carrying dies 9 is mounted on a reciprocable ram 5. Also mounted on the ram is an electrically operated heating box 44 and the foil feeding and supporting rollers 7, 8, the feed rollers being actuated automatically pursuant to movement of the ram. The ram is reciprocated by an electric motor (not shown), as infinitely variable speed gear 22, a clutch 23, an epicyclic gear (not shown), a chain 26, a crankshaft 27, a link 29, a rocker lever 30, a link 31, and a second rocker lever 32, one end of which is pivotally connected to a block slidably received within an opening in the ram 5. The clutch is operated by a clutch lever 25 which is controlled through a flexible cable by a pedal (not shown) and carries a striker 36 co-operating with a pin 37 carried by a wheel on the crank-shaft so that the clutch is disengaged after one cycle, the striker being controlled by a member (not shown) so that it can be moved out of the path of the pin 37 and the clutch is then under control of the pedal. The outer element of the epicyclic gear is coupled to a hand wheel 39 with which is associated a locking collar 40, the collar being tightened when the ram is motor driven and the collar being released when the ram is hand driven by means of the wheel 39, a uni-directional mechanism preventing the rotation of the motor. Mounted on the shaft of the rocker lever 30 is an oscillatory arm (not shown) which drives through a link 10 the foil feeding rollers, the connection between the arm and the link 10 being adjustable to vary the feed of the foil. A spindle 33 on which the rocker lever 32 is freely mounted has eccentric end portions and one of the end portions has an actuating member 34 by means of which the distance between the upper and lower platens can be adjusted so that the correct pressure can be exerted on the work during a marking operation.
