Title: Improvements in or relating to the treatment of green clay, shale or the like goods such as bricks, before burning
IPC: B28B11/08
Filed: 1933-06-09
Abstract: 422,269. Treating unburned bricks and like goods. BAILEY, H. H., Royal Oak Hotel, Kelsall, Cheshire, and GILL, J. F., 14, Dale Street, Liverpool. June 9, 1933, No. 16513. [Class 87 (i)] Unbaked bricks and like goods are given a rusticated appearance or indented on the faces by means of bristle brushes 38, 41, 42 which are moved to and from the travelling goods in a path which has a component of motion in the direction of travel of the bricks during engagement therewith by the brushes. The bricks are carried by an endless belt 17, and the brushes are actuated by eccentrics such as 37, there being two pairs of eccentrics for each brush, i The main shaft 20 drives the horizontal eccentric shafts 28, 29 by chain gearing 24, 25, and the vertical eccentric shafts, such as 31, are driven from the shafts 28, 29 by bevel gearing 35 housed in floating casings 36 slidable on the squared ends of the shafts. Adjustment of the brushes normally to the bricks is effected by internally screwed sleeves 52 and worm gearing 59, 61 operated by hand-wheels 67, 68. Automatic displacement of the brushes on their mounts is obtained by eccentric headed studs 45 engaging slots on the brushes and carrying ratchet wheels 47 which engage stationary pawls 49, so that the main motion of the brushes gives a step-by-step movement about the studs. To maintain the predetermined relative speed of brushes and belt 17, a switch arm 85 is moved over a field resistance of the motor by an arm 83 which is rotated by the differential gear 84 when there is a variation of speed. Sand is supplied by hoppers 90 through slots 89. In another arrangement, groups of bristles are mounted on an endless belt, the supports for which are moved towards and away from the clay column, the belt being driven either by the clay or independently. In a further modification, each belt is mounted upon four rollers in a row, the two inner rollers being nearer the clay column than the outer rollers so that the central part of the belt is parallel to the column, and the end portions of the belt are inclined thereto.

Title: Improvements in cam-cutting machines
IPC: B23Q1/50
Filed: 1923-06-27
Abstract: 201,535. Soc. Anon. des Etablissements Ballot. July 27, 1922, [Convention date]. Milling-machines.-A machine for cutting cams of the kind described in Specification 201,534, [Class 103 (i), Brakes &c.], chiefly intended to be used for controlling the front-wheel brakes of motor vehicles, comprises two milling cutters and a work-holder secured to a disc which is rotatable on a pivot carried by a cradle revoluble about a horizontal axis and lockable in spaced positions, the whole being also movable about a vertical axis. The work-holder consists of a sleeve revoluble. on its axis and is indexable in various .angular positions. The cutters may be fixed and the work movable, or vice versa, or both may be movable. The sleeve 20, in which a shaft 21 carrying a rectangular block a to form the cam is secured by a nut and split cone 22, is revoluble in a head 18 and is indexable by means of a notched disc 25 and a spring plunger 26. The head is secured to a disc 13, revoluble by means of a worm 16 and a sector 15 about a pivot 14 carried by a cradle 5 which is rotatable about horizontal pins 6, 6<1> mounted on a frame 4 revoluble about a vertical axis 3. When the pivot 14 is vertical, its axis coincides with the axis 3. The cradle is indexable by means of a notched disc 8 and a plunger actuated by a lever 12. The cutters, of which one is indicated at 27, are disposed in two parallel planes at each side of the pivots 3 and 14. In operation, the block a is set in the position shown and the disc 13 is rotated by means of a wrench on the worm shaft 17 through a distance corresponding to the movement of the front wheels of the motor vehicle during steering, the cutters meanwhile generating ,a cylindrical surface on the block. The shaft 21 is then turned on its axis through an angle of 15 in either direction, according as the cam is designed for a right or left hand wheel, this angle being the estimated rotation required to be given to the cam to compensate for wear in the brake segments. The cradle is next rotated about the pins 6, 6<1> through an angle of 15 so as to return the side faces of the block to a vertical position, and the disc 13 rotated as before, when the cutters will generate a conical surface. To form the upper and lower surfaces of the cam, the block is returned to its initial position, the cradle is rotated about the axis 3 to bring the axis of tha shaft 21 in a plane parallel to the planes of the cutters. The cylindrical and conical surfaces are then generated as before. Fig. 1 in the original form as open to inspection under Sect. 91 (3) (a) shows the train of gears A. This gearing is not shown in the Figure as accepted.

Title: Improvements in spring hinges for doors
IPC: E05F1/12
Filed: 1930-05-30
Abstract: 343,408. Spring hinges and checks. KREINER, F., 37, Hindenburgstrasse, F³rth, Bavaria, Germany. May 30, 1930, No. 16727. Convention date, June 13, 1929. [Classes 65 (i) and 65 (ii).] The lower socket 4 of a hinge is sealed at the ends by caps 5, 18, and screwed over the cap 18 is a bearing tube 20 over which an upper socket 3 fits. One end of a torsion spring 33 engages in a slot in the part 18, and the other end engages in a part 35 of which the regular polygonal upper part enters a corresponding hole in a ring 37. This ring has projections which engage with the socket 3, so that as the door is opened the spring is stressed. The initial stress in the spring may be raised by turning a member 35 before placing the fixing ring 37 over it, the tube 20 and socket 3 being cut away to allow the insertion of a key in holes in the member 35 for this purpose. Checks.-A cap 29 also has projections engaging with the socket 3, and a rod 24 is fixed to the cap either by a square end of the rod entering a star-shaped hole in the cap or by a transverse pin and several holes, each method allowing of initial angular adjustment. An enlarged lower end of the rod 24 has lateral projections 25 engaging in grooves 8 in a piston 7. The upper ends of these grooves are horizontal, but their main parts are helical, so that, as the door opens and the rod 24 turns, the piston 7, which is prevented from rotating by ribs in the socket 4, is forced to rise when the projections 25 enter the helical parts of the grooves. A ball valve 11, normally partly open, then opens fully against a spring 10 to allow liquid to pass from above to below the piston. During closing of the door, the valve will offer resistance to the return of liquid, thus checking the motion, and when the piston reaches the bottom of its stroke the valve is almost completely closed by an adjustable stop 12, giving a stronger check at this point. By varying the angular position of the rod 24 in the cap 29 the entry of the projections 25 into the helical parts of the grooves 8 may be made to occur at the commencement of opening or later, so that the checking action may continue until the closing is complete or may cease while the door is still partly open.

Filed: 1949-06-24
Abstract: 675,576. Electric correspondence control systems. FOUASSIN, M. June 24, 1949. [June 25, 1948] No. 16851/49. Class 40 (i) A control system for adjusting a mechanism to a particular angular setting consists of a coarse, fine and very fine selsyn system which take over control consecutively, the amplified error voltage in any one selsyn being used to block the operation of the finer selsyns and being fed to a servomotor via a rectifier circuit which is sensitive to the phase of the voltage. As shown, a shaft 4 is controlled by the position .of a handle 2 attached to a shaft 5, which is split into three sections 15, 16, 17 coupled together by reducing gear 34, 35. Shaft 4 is similarly split into three parts 18, 19, 20 by gears 36, 37, corresponding parts of each shaft being interconnected by selsyns 9, 12, 10, 13 and 11, 14, so that angular displacement between the shafts produces an error voltage in each of the receiving selsyns 12, 13, 14, which is fed to individual valve amplifiers 25, 26, 27. A bias voltage for the valves of amplifier 26 is developed across a resistor 45 from the rectified output of amplifier 25. This is augmented in a similar way by the rectified output of amplifier 26 to produce bias for the valves of amplifier 27. Thus each amplifier is cut off until the error voltage of the preceding stage is below a certain value. The output of each channel is fed through separate rectifier circuits 68, 69, 70 to give a D.C. voltage varying in magnitude and direction depending on the magnitude and phase of the error voltage, and taken to a control unit 43 which feeds a motor 3 driving the shaft 4. Particular settings of the shaft. 4 may be obtained by a series of preset settings of control 2, which may be chosen by a multi-bank changeover switch.
