Title: Mechanical servo brake
Inventor: BUTLER HENRY JAMES
IPC: B60T13/02
Filed: 1954-03-16
Abstract: 756,204. Mechanical servo brake. DUNLOP RUBBER CO., Ltd. March 1, 1955 [March 16, 1954], No. 7546/54. Class 103 (1). In a mechanical servo brake comprising a rotatable disc, a brake shoe frictionally engages the outer periphery of the disc and is angularly movable thereby to actuate means for effecting frictional engagement between pads of friction material and the radially-extending sides of the disc. In the embodiment illustrated in which Fig. 2 is a view in direction A of Fig. 1, a mechanical servo disc brake suitable for heavy vehicles comprises an annular disc 1, rotatable with a driving shaft, which may be initially braked by a pair of substantially semi-annular brake shoes 5, pivotally secured together at two adjacent ends, which almost completely encircle the periphery of the disc 1. Each shoe is provided at its centre on each side with a cam member 9 with which co-operates a roller 10 rotatable in bearings 11 about a spindle 12. Each spindle is set in the end of an arm 13 which extends substantially parallel to the major axis of a rigid channel member 3 which acts as a torque member. Each of the channel members 3 is provided adjacent its ends with a pair of cylindrical bosses 15 in which a shaft 16 integral with the end of each arm remote from the cam 9 and roller 10 is rotatably fitted on needle bearings 17. Each shaft is provided with an eccentrically-mounted screwed member 18 which extends inwardly towards the disc such that angular movement of each arm 13 in one direction rotates the shaft 16 to move the screwed member 18 towards the disc to bear on pressure plates 19 to which are secured segmental friction pads 20 which frictionally engage the radially-extending sides of the disc. In operation, on tensioning the brake cable 7, the brake shoes 5 are tightened about the outer periphery of the disc 1 and commence to rotate in the direction of rotation of the disc which forces rollers 10 to ride up one of the slopes of each of the cam-members 9, thereby moving each arm 13 to effect rotation of each shaft 16 such that screwed members 18 force the pressure plates 19 towards the disc to frictionally engage the associated friction pads 20 with the disc. Excessive angular movement of the shoes 5 is prevented by stops 21 on the shoes 5 which contact the ends of the bridge-pieces 4 secured to the torque members 3; the bridge-pieces also acting as guides for the shoes 5. Springs 14 and 8 return the members to their inoperative positions when the tension in brake cable 7 is removed. Provision may be made for the incorporation of automatic retraction and wear adjustment devices and in an alternative construction (not illustrated) the primary brake shoes 5 may frictionally engage the external surface of a drum extending axially from the periphery of the disc. To assist cooling of the disc 1 a plurality of axially-aligned holes 2 may be provided which also restrict transmission of heat to the shaft and associated bearings. Specifications 631,877 and 747,972 are referred to.

Abstract: 1,214,584. Valves. ROBERT BOSCH G.m.b.H. 16 Feb., 1968 [18 Feb., 1967], No. 7603/68. Heading F2V. A valve adjusting knob 10 moves a closure member 4 by means of a non-rotatable spindle 19 secured in a plug 18 screw-threaded into a member 16 which is splined into a bore 14 in the knob, the knob being movable into a recess 7 in a cover 6, against the action of a spring 9, and a lockable stopping pawl 27 retains the knob in the innermost position, the depth of the recess 7 corresponding to at least the height of the knob. The knob 10 has an annular shoulder 12 which is engaged by a portion 31 of the pawl 27 after the pawl has been forced back against a spring 29 during insertion of the knob. To release the knob, a key 37 is used to rotate the pawl about an axis 28 and allow the knob to be pushed out of the recess by the spring 9. In the locked position, the knob prevents the closure member 4 from moving by frictional engagement of the base of the knob with a disc 25 and a spindle guide member 21. The disc 25 rotates an indicator 24. A further indicating scale (38), Fig. 1 (not shown), is formed around the knob opening in the cover 6. In Fig. 4 (not shown) the knob (10<SP>1</SP>) is locked by a reciprocating bolt (43).

Abstract: 589,761. Loft ladders. DEWAR, W. April 2, 1945, No. 8155. [Class 20 (ii)] Relates to ladders of the kind stowed in lofts and extended for access thereto when the trap door is opened. The ladder, Fig. 1, comprises a top section 18 hinged to the floor of the loft, an intermediate section 16 hinged to the top section, and a lower section 12 hinged to the intermediate section. The top section 18< >which is flat and has side flanges 21, lies on the floor of the loft when the ladder is extended, thus forming a tread. The leaves and intermediate sections slide in parallel grooved inner members 1, (Fig. 3) pivoted at 2 to parallel guide members 3, members 3 being pivoted at 5 to the trap door 6 and resting on a roller bearing 7. To return the ladder to its closed position the lower section 12 is pushed upwards, sliding in the inner members 1 until its lower end is above the free edge of the trap door. The guide members 3 are then rocked round the roller bearing 7 until the trap door is closed. These movements cause the upper section 18 to turn over, until its side flanges 21 come to rest on the floor of the loft, and cause the intermediate section 16 to fold under the lower section 12, so that the ladder is stored in the loft in collapsed condition. The inner members 1 are provided in view of the arcuate course described by the top end of the intermediate section. 8 are rods pivoted to the floor of the loft at 9 and penetrating handle-forming upper extensions 10 of the guide members 3. Stops 11 on the ends of rods 8 restrain the rotation of guide members 3 when the ladder is opened. A system of cords and pulleys (not shown) attached to a weight on spring prevents the ladder from taking control when it is being lowered.
