Patent GB-547556-A (GB)
Title: Centreless grinding machine
IPC: B24B5/18
Filed: 1940-11-15
Abstract: 547,556. Centreless grinding-machines. LIDKOPINGS MEKANISKA VERKSTADS AKTIEBOLAG. Nov. 15, 1940, No. 16555. Convention date, Nov. 4, 1939. [Class 60] In a centreless grinding-machine, the grinding and regulating-wheels are so mounted on slides as to be relatively movable in directions which are inclined to one another at an obtuse angle, the point of the angle being directed away from the machine bed. In the construction shown in Fig. 4, slides 2, 4 carrying the grinding-wheel 1 and regulating-wheel 3 are arranged at an obtuse angle having the point directed away from the machine-bed 10, the angle being equal to 180-V degrees when V is the angle, preferably 10 degrees, between the tangent-planes of the work-piece 6 and wheels. The workpiece is arranged above the narrowest part of the grinding throat. The arrangement simplifies setting, since the angle V can be maintained constant, regardless of the size of the workpiece or wear of the wheels, merely by so adjusting the height of the work-support 5 that the axis of the work-piece coincides with the intersection of the planes c-c, d-d in which the axes of the wheels travel. Theregulating-wheel 3, instead of being mounted directly on the slide 4, may be mounted on a support 12 which can rotate on an axis intersecting the axis of the regulating-wheel at right-angles. By this arrangement a regulating-wheel shaped to have line-contact with the work-piece when tilted in one direction will also have line-contact when tilted equally in the opposite direction, thereby enabling the machine to be employed for through-feeding of a long work-piece in opposite directions alternately. The regulating- wheel is shaped by a truing-tool 13 which moves in a rectilinear path parallel to the through-feed direction, and is arranged diametrically opposite the contact-line of the regulating-wheel and work-piece. In the machine shown in Fig. 7, the grinding-wheel slide 2 is carried by a support 14 which is adjustably mounted on cylindrical surfaces 15 having the intersection of the planes c-c, d-d as axis, the arrangement enabling the angle between the tangent-planes of the work-piece and wheels to be varied. The Specification as open to inspection under Sect. 91 describes also a machine in which the grinding-wheel or regulating-wheel is mounted on two slides of different inclination. This subject-matter does not appear in the Specification as accepted but now forms the subjectmatter of Specification 547,557.

[Classes 5 (ii) and 58.] A method of treating kaoliang comprises steeping in tepid water until the bran and inside skin become slightly soft, removing it from the water, mixing therewith dried bran of kaoliang and stirring it, so that each grain becomes coated with bran, removing the excess bran, for example, by means of a winnower, and passing the coated grain between a fixed wire net and moving rubber face of a decorticating machine whereby the bran, embryo bud and inside skin are removed. The bran is used as cattle food, the inside skin as raw material for cattle cake and other animal foods and the embryo bud as a source of kaoliang oil. The kaoliang is first husked and sorted and part of the bran obtained from the treatment is dried for use in the treatment. A decorticating machine for use in the treatment comprises a member 1 having a spirally grooved rubber lined concave face 2 and rotated about a vertical axis. A convex wire net member 8 is supported adjacent the face 2 by springs 7 on a vertically adjustable frame 6. The machine also comprises a hopper 9, a discharge shoot 16 for the bran, and a trough 10 whence the grain is swept by a brush 15 into a discharge shoot 11.

Class 87 (ii) [Also in Group XXIX] A press of the twin type comprising two pairs of relatively movable elements (i.e. pressure plates or platens) which are mechanically interconnected by at least one flexible or jointed member in such a manner that as the distance between one pair is decreased the distance between the other pair is automatically increased. The press comprises upper and lower pairs of platens 37, 35. Upper platens 37 are actuated through rods 36 by toggles 45, 46 and lever 43, the toggles being arranged to raise one of the platens as the other is lowered and vice versa. The lower platens are actuated by toggles 39, 40 which may be pulled into alignment by means of chains 52 connecting them to a pair of treadles 54. The treadles are interconnected by a chain 56 which raises the inoperative treadle as the other is depressed. Cams 51 actuated by the lever 43 through chain 47 and sprockets 48, 49 are arranged to engage in turn the knees of corresponding toggles 39, 40. Each of the cams is arranged to "break" the toggle 39, 40 of a lower platen 35 and hence to lower this platen as the corresponding upper one is raised, both these actions being caused by movement of the lever 43.

[Class 4] A retractable landing-gear for an aircraft comprises a wheel-carrying leg A1 pivoted at 1 to the aircraft to swing between the extended position shown in full lines and the retracted position shown in dotted lines, and a locking member, shown as a toggle 7, 8, pivoted at 2 to the aircraft and at a1 to the leg A1, the pivot point a1 moving in an arc about the point 1 during movement between the extended and retracted position, and the points 1, a1 and 2 forming symmetrical triangles in the two extreme positions. As shown, the toggle links 7, 8 are provided with shoulders 14, 15 preventing braking of the toggle in the wrong direction, and these shoulders are engaged in the extreme positions of the landing-gear by a recess 13 in a locking lever 11 mounted on the pivot a1. The actuating link from the jack (not shown) is pivoted at 16 to the lever 11 so that on initial operation of the jack the lever 11 is turned to disengage the shoulders 14, 15 and then to move a stop 12 against the toggle link 8 to break the toggle and move the linkage. A spring 17 lowers the landing-gear if the jack fails. The lever 11 may be omitted, the link V being connected directly to an extension of the link 8. The positions of the pivots 1 and 2 may be interchanged. In an alternative construction the toggle 7, 8 is replaced by a link pivoted at a1 to the leg A1 and having a slot engaging a pin secured at 2 to the aircraft. The slot may be bent at the end so that the action of the jack locks the landing gear in position.

In the retracted position the pressure of the compressed gas only acts on the small area of a projection 54 passing through an aperture 31 in the end of the inner tube 17 whereby the pin 43 is only lightly loaded. A seal 34prevents the escape of the gas to atmosphere through a restriction 70, Fig. 5 (not shown).
