Title: Divided bearings
IPC: F16C35/00
Filed: 1975-01-03
Abstract: 1480191 Journal bearings DAIMLERBENZ AG 3 Jan 1975 [9 Jan 1974] 281/75 Heading F2A A journal bearing of the kind divided into two parts at a substantially diametrical plane and having holes for cover bolts in which the surfaces of the parts of the bearings that are in contact when the bolts are tightened are, when the bolts are untightened inclined to each other at an angle of 15-60 minutes of arc seen in the direction of the longitudinal axis of a member journalled in the bearing. In one embodiment, surfaces 6 and surfaces 7 and 9 are shaped to form an angle α of about 30 minutes, between the parts 1, 2 of a journal bearing in which the axes 5 of bores 4 are located to the bore (3) side of midwidth points 10, 11. The angle may be obtained by removing material from either or both of parts 1, 2. The angle is such that, when bolts in bores 4 are tightened to a quarter of the fully tightened torque, the surfaces are in overall contact, so that when the bolts are fully tightened, the pressure over the surfaces is uniformly distributed. The invention may be applied to journal bearings having serrated adjacent surfaces.
Patent GB-937344-A (GB)
Title: Improvements in and relating to machinery for and method of making wire cords
Inventor: MELDRUM JOHN IRVING
IPC: D07B7/02
Filed: 1960-01-05
Abstract: 937,344. Machines for making wire ropes. COURTAULDS Ltd. Jan. 4, 1961 [Jan. 5, 1960], No. 312/60. Class 109. A machine for making wire strands and stranded wire cords comprises a rotatably mounted die 8, a capstan wheel 22 having an axial bore and mounted for rotation coaxially with said die 8, the capstan wheel and the die being capable of rotation at different relative angular velocities, a lead-on guide 12, 16 rotating with the die 8 to determine a cord path from the die 8 to the periphery of the capstan wheel 22 so that the cord can be wrapped around the capstan wheel, and lead-off guides 19, 15, Fig. 2 (not shown), to determine a cord path from the periphery of the capstan wheel to the bore of the capstan wheel so that the cord may travel along said bore away from the die 8. In a particular example, seven wires 32, each spinning right-handedly about its axis at 12,000 r.p.m., are drawn through a lay plate 7 to enter the die 8 rotating at 12,000 r.p.m. in the same sense as the wires 32 so that the die 8 twists the wires 32 about each other to form a cord 33. The cord 33 is thus formed without twisting any individual wire 32 about its own axis. The cord 33 passes through a trumpet guide 9 and thence over guides 12 and 16 on a capstan chamber 20 to the capstan wheel 22, the chamber 20 rotating with the die 8 so that there is no tendency for the cord 33 to roll or untwist when in contact with said guides. The cord 33 is wrapped two or three times around the surface of the capstan wheel 22 so that, with the capstan wheel rotating at 12,375 r.p.m. in the same sense as the die 8 and chamber 20, a tractive force is applied to the cord 33. The difference in speed, namely 375 r.p.m., is a measure of the linear speed of the cord 33 through the machine. The cord leaves the capstan wheel over further guides on the capstan chamber 20 to pass by way of a radial guide 15 into a channel 26 leading to a bore in the spindle 27 of the capstan wheel and from which the cord 33 is collected. By running the capstan 22 at a slower speed than that of the die 8 a cord of opposite twist, to that in the above example, is formed. As the cord 33 leaves the machine it is still spinning on its axis at 12,000 r.p.m. and this spinning can be neutralized by collecting the cord in a double twisting device which sets up an equal and opposite rotation. Specifications 287,202 and 434,435 are referred to.

Title: Improvements relating to control apparatus for colliery and other like winding engines
IPC: B66B1/12
Filed: 1942-01-10
Abstract: 552,345. Winding controls. BLACK, G. A. Jan. 10, 1942, No. 396. [Class 78 (v) In rotary profile and associated centrifugal governor control devices for colliery and like winding engines, whereby a trip mechanism is operated to effect braking or other retarding or stopping means when excessive speed is attained, an inertia device is added to apply a brake, &c. when excessive acceleration takes place. A governor d mounted on a shaft c driven by skew gearing j, k from a lay shaft i pinion-driven from the power shaft f, has rolling spring biassed masses a which rock a lever 6 pivoted to a framework through a link 7. The lever 6 is coupled by a connecting rod 5 to a lever 4 rocking about one end of a floating main lever u. The free end of the lever 4 carries fingers 4a adapted to raise pins s which enter between a three-cornered cam p carried by the shaft c and embracing arms q pivoted to spaced spindles r and coupled together by stud and notch connection q<SP>1</SP> so that when one is pressed outward the other also moves outward. To one of these arms q is coupled a link whereby a brake or other engine retarding or stopping means is operated. The fingers 4a can also be raised by the rotating profile cam e, which is fitted with adjustable outlines o to suit different conditions. A roller 3 riding on the rim of the cam e is constrained to move in a circular path by an arm y and is linked at x to one end of a lever v rocking about a framework pivot. The other end of the lever v is pivoted to the main lever u, so that up and down motion of the roller 3 is translated into up and down movement of the fingers 4a. Hand control of the fingers 4a is also provided, this being from a push-button 10 connected to a lever 9 swinging about a frame bracket w and joined by a link 8 to the end of the lever u. The inertia device comprising the subjectmatter of the invention consists of a fly-wheel 14 turning freely by bearings 15 on a shaft 12 and carrying a projecting nut 13 helically grooved to fit over a screw thread on a sleeve 22 slidable over the shaft 12 but coupled thereto by a pin 16 to which is fixed an extension spindle 17. This is engaged by a rockable T-lever 19, one top-arm of which is connected by a link 21 to the lever 9, the other top arm bearing on a cross-pin on the link 8. Sudden changes of speed of the engine will cause the fly-wheel driving sleeve 22 to move axially, or through the spindle 17 to swing the arm 19 and press down the lever u at that end, thus raising the other end and also the fingers 4a. In a modification the governor drive is through a crank pinned to the driving crank pin of the engine, this pin working in a slot formed between two spring- pressed enclosing arms on the governor crank. Extra pressure on one of these arms due to excessive acceleration turns it through a small angle relative to the crank and by way of a Bowden wire and a spindle passing through the crank-shaft operates the brake, &c. The brake &c. actuation may be fluid operated.
