Abstract: 890,223. Vibratory mechanisms. BRITISH STEEL PILING CO. Ltd. Nov. 3, 1959 [Nov. 7, 1958], No. 35882/58. Classes 80 (3) and 80 (4). An impulse vibrator for pile driving comprises a flywheel 12<SP>1</SP>, driven from a prime mover 10<SP>1</SP>, and a floating link 18<SP>1</SP> which is journalled at one end on a crank-pin 16<SP>1</SP> on the flywheel 12<SP>1</SP> and is pivotally connected at a point intermediate its ends to a rocker link 241. The mass of link 18<SP>1</SP> is concentrated at its free end which is caused to follow the path CDE. At E, the sudden change in direction of the mass 18<SP>1</SP> causes tension in the rocker link 24<SP>1</SP>, which is pivoted on a shaft 22<SP>1</SP> mounted in an outer frame 2<SP>1</SP> attached to the head of a pile 41, and is thereby transmitted as a driving impulse on the pile 4<SP>1</SP> An inner frame 6<SP>1</SP> carries the flywheel 12<SP>1</SP> and prime mover 10<SP>1</SP>, and is resiliently supported with respect to the outer frame 2<SP>1</SP> by leaf springs 8<SP>1</SP>. Fig. 2 shows an arrangement in which three flywheels 12a, 12b and 12c are employed for balancing stray transverse forces, the inertia of each of the outer coaxial systems being half that of the central system. Lubricating pumps 44 actuated by eccentrics on the flywheels 12a, 12c deliver oil to all the bearings.

Abstract: 809,977. Ultrasonic abrading machines. MULLARD Ltd. Oct. 8, 1957 [Nov. 30, 1956], No. 36687/56. Class 60. [Also in Groups XVI and XXXII] An ultrasonic work machine, which vibrates a tool at ultrasonic frequency in an abrasive slurry to provide means for cutting, boring or engraving hard and brittle substances, such as glass or quartz, comprises an electro-mechanical transducer-tool assembly mounted for linear movement under the action of its mass over a predetermined range of travel, in all positions of which adjustable counter-balancing means are so arranged as to provide a substantially constant and predetermined counter-balance force on the assembly. The tool-assembly (not shown) is carried on a bracket m depending from a vertically-adjustable rod a formed with grooves j which provide bearing surfaces for balls i engaging similar grooves in a fixed housing h; the housing is split to permit adjustment of the friction between it and the rod. A flexible metal link b is secured at one end to the bracket and at the other end to the profile of a cam c which is upwardly-urged about a pivot n by springs d attached to a block e vertically-adjustable by means of a screw g. The weight of the tool assembly can thus be counter-balanced by an amount which is determined by adjustment of the springs d and remains substantially constant during the vertical movements of the tool-assembly by virtue of the variation of force applied by the springs to the cam during its rotation about the pivot n and by the effect of the profile of the cam on the link b. The vertical position of the tool-assembly can be determined by means of a scale k on the rod a and a magnifying lens l on the housing h.

IPC: F16D55/224
Filed: 1959-11-03
Abstract: 908,661. Disc brakes. GIRLING Ltd. Feb. 3, 1961 [Nov. 3, 1959], No. 37221/59. Class 103 (1). A disc brake for the rail wheels of a vehicle of the kind having both road and rail wheels comprises brake shoes (Fig. 3, not shown), adapted to engage braking surfaces on opposite sides of a disc-like annulus 10a of a rail wheel 10, or an associated separate disc, the shoes being pivotally mounted on the inner ends of a pair of calliper levers 13, 14 coupled together by a yoke or link 15, the outer end of one lever being pivoted on a member 16 which is normally stationary but movable by hand-operated mechanism 17 for applying the brake manually, and the outer end of the second lever being actuated by a fluid - pressure motor 23 through a lever 22 which fulcrums on an abutment 18 which is automatically advanced by an automatic slack adjuster 27 (not described in detail) to compensate for wear of the friction pads on the brake shoes. The adjuster 27 has manually-operated means 31 for resetting it when new pads are fitted. The motor 23 is of diaphragm type operated by vacuum and acts on a positively guided rod 25 coupled to the lever 22. A further lever 28 and link 29 couple the rod 25 to the adjuster 27. The motor 23 is actuated either separately or in conjunction with a similar but larger motor acting on a similar brake (Fig. 2, not shown), acting on the other rail wheel of a pair, the two wheels being carried on an axle 11. Control of the two motors is via a valve which may be a manually-operated valve (Fig. 5, not shown), or a valve adapted to be operated automatically in accordance with the load carried by the vehicle, the valve having three positions in which vacuum is applied to one, the other, or both of the motors respectively, thus providing three different degrees of braking. The hand-operated mechanism 17, which is provided for only one of the wheels (the outer end of the lever 13 on the other brake being mounted on a fixed pivot) comprises a hand wheel for manually rotating a screw 58, Fig. 4, which co-operates with a nut 59 which is pivoted at 61. The rear face of the hand wheel bears on one end of a lever 51 which rocks about an abutment 53 to cause movement of the member 16 via a pivotal connection 52, the member 16 being slidable in sleeves 44 and biased in a direction towards the rail wheel by a spring 46.
