Title: Improvements relating to semi-trailers and anti-jack-knifing devices for use therewith
Inventor: BUTLER ROBERT
IPC: B62D53/08
Filed: 1969-03-12
Abstract: 1298342 Anti-jack knifing arrangements TOLLBRIDGE ENG Ltd 12 March 1970 [12 March 1969 12 May 1969] 13100/69 and 24191/69 Heading B7T An anti-jack knifing arrangement for a semitrailer comprises a king-pin 36 rotatably mounted in a base-plate 32 and having extending therefrom a lever 40 which prevents relative rotation between the king-pin and a fifth wheel to which it may be coupled, and there being further provided on the king-pin oppositely extending levers 52 connected with piston-rods 54 of hydraulic rams 56 such that during articulation between the semi-trailer and a towing vehicle, fluid passes from one ram to the other through a restriction 60. The restriction may be of such a dimension that it has no effect on normal articulation but offers substantial resistance if the rate of articulation is greater than normal, i.e. during jack knifing. In one arrangement the restriction comprises a valve linked to the trailer brakes providing restriction proportional to the braking effort. Alternatively the valve may be responsive to the pressure differential across it. The restriction may be responsive to manual control. The single-acting rams illustrated may be replaced by doubleacting rams with the ends of the cylinder of each ram connected to each other or to the corresponding end of the cylinder of the other ram. Alternatively a single double-acting ram may be provided with the ends of its cylinder connected by a balance pipe including the restriction. The mechanical linkage disclosed in the present Specification for steering the trailer wheels forms the basis of Specification 1298341 and may be replaced by an hydraulic linkage connected with the anti-jack knifing arrangement.

Abstract: 595,322. Brakes. AUTOMOTIVE PRODUCTS CO., Ltd., and GATES, G. R. G. Dec. 4, 1944, No. 24231. [Class 103 (i)] An adjuster for an internal shoe drum brake comprises an angularly movable cam 27 with notched edge, which is pivoted on the web 24 of a brake shoe 12 and is engaged by a projection 34 carried by the head 22 of an actuating hydraulic plunger 18. The actuator for the shoe 13 is provided at its lower end, the anchorage for the shoe 13 at the upper end being provided by the fixed cylinder 17. The cam 27 comprises similar elements on the two sides of the web 24, mounted on a spindle which is housed in a recess 25 in the web, and which has a screwdriver slot in its end by which the cam may be adjusted. In alternatives, the adjuster may co-operate with an anchorage fixed to the back-plate, either the cam or its follower being mounted on the backplate to serve as the anchorage, or it may be used with shoes of the floating type which engage an abutment at either end, either between the shoe and a spreading device which serves also as an abutment according to the direction of rotation, or between the shoe and an abutment which is independent of the spreading device but which receives the braking force from the shoe.

Abstract: 1434126 Combine harvester with grain unloading tube INTERNATIONAL HARVESTER CO 22 May 1973 [23 May 1972] 24247/73 Heading A1F A combine harvesting machine comprises a grain unloading tube pivotally mounted about an inclined axis 3 so as to be capable of taking up either a horizontal and inward transport position or an outward and upwardly inclined working position. The tube is further supported 'by a flexible or rigid tie 8 which is pivoted to one end of an angled compensating lever 12 the other extended end 14 of which may be pivoted to the combine top Figs. 3, 4. The lever 12 is also pivotally connected to a tension spring 24, Fig. 4, via a crank arm 22. The spring 24 acts with small mechanical advantage in the transport position but with a large advantage in the working position. When the tube is pivoted to take up its transport position in recess 5 the slack appearing in tie 8 is taken up 'by the compensating lever being returned in the direction opposite to the arrow f by the action of the spring 24. The pivoting of the lever to allow the tube to take up its working position is limited by stop 21. In a modification the compensating lever is pivoted to the top of the tube itself, Fig. 7, rather than the combine and with the tie forms a dead-point overstepping system which is urged against the stop by the spring. The end of the tie not connected to the lever is pivotally connected to the combine at 29.

As shown, the sheet, after coating, may be heated as at 5, or pressed between heated platens as at 6, or heated and passed between rolls 7 to cause the synthetic resin to stick to and impregnate the sheet. It may be used immediately or after trimming, cooling and storage to apply a decorative surface to the inside of a bowl. Paper, if used, may be of man-made fibres, e.g. rayon; fabrics, if used, may be thin. The process may be continuous. The aminoplast may be a product of formaldehyde and benzoguanamine, acetoguanamine, 2-cyclohexyl-4, 6- diamino-S-triazine, or melamine. Dimethylol ethylene urea may be added as a plasticiser. The catalyst may be magnesium chloride. The aminoplast and catalyst may be applied as a solution, in which case it must be dried.

Abstract: 1,010,757. Two-pad couplings. BELLING & LEE Ltd. June 12, 1964, No. 24417/64. Heading H2E. An electrical contact which comprises a single strand of wire bent back on itself to form two limbs 1, 2 (Fig. 3), is arranged in an edge connector block of insulating material in such a way that one limb 2 acts as a support and the other limb 1 which is hooked at its end around the limb 2 so bears on a printed circuit board during its insertion into the connector that the bearing pressure on the limb 1 causes the hook to disengage from the limb 2. The support limb 2 of the electrical contact may be welded at its end 9 to a terminal post which may be formed from a strip of metal with a protruding tongue 12 for preventing the contact from inadvertently falling from the block and either with a solder tag 15 (Fig. 5 not shown), or with a double thickness wrapped wiring terminal tag 10, 11 (Fig. 3).

In a socket for mounting a tool, chuck, &c. on a machine-tool spindle, the connection is by a bayonet joint and clamping by components movable transversely by a rotatable-ring on the spindle. The spindle 1, Fig. 1, journalled in a sleeve 2, has a conical socket 3 and a flange 4 engaging a cone 7 and flange 8 of the tool or chuck 5. The cone 7 has two wings 13, Fig. 4, engaging lugs 14 in the socket 3. An axiallyslidable pin 15, Fig. 1, in a bore 1<SP>1</SP> of the spindle 1, has extensions 16, 17, of unequal width, to pass through bayonet-slots in a bore 9 of the tool 5, and then be rotated in a recess 10 to lock behind lugs 9<SP>1</SP> of the tool and engage wings 13 with lugs 14 for a driving-connection. The clamping-means include two pressure-pins 22, 23 slidable in a transverse bore 21 in the spindle 1, and rollers 19, 27, the roller 19 being journalled at 20 in a slot 18 of the pin 15 and the roller 27 being inserted between roller 19 and a plate 25 resting on spindle 1. The pressure-pin 23, in a transverse bore 21 of the spindle and splined at 26 to a groove 24 in the bore, may be moved radially by an internal cam-surface 28<SP>1</SP> on a ring 28 rotatable on the spindle, thus moving roller 27 radially inwards and roller 19 vertically upwards to raise pin 15 and lock the tool axially by the extensions 16, 17. To release the tool, reverse rotation of ring 28 allows the spring-plunger 22 to move roller 27 radially outwards and a spring 32 to move pin 15 downwards, releasing axial pressure on extensions 16, 17 so that the tool may be rotated to disengage the bayonet connection. The roller 27 is preferably in line with the axis of pin 15 when in the clamped position, to give a toggleaction during clamping.
