Title: Stacking device for bricks or the like
Inventor: LAIRD JOHN STEPHEN
IPC: B65G47/91
Filed: 1960-09-25
Abstract: 970,210. Stacking bricks. SUTCLIFFE, SPEAKMAN & CO. Ltd. Sept. 21, 1961 [Sept. 25, 1960; June 27, 1961], Nos. 26372/60 and 23306/61. Heading B8A. Bricks, Fig. 2, are discharged from press table B by an off loader A on to a belt C. The belt C delivers the bricks in rows to a grab D which removes them from the belt and discharges them on to a trolley E (not shown). Off loader A, Figs. 3, 4 and 5.-The off loading is done by suction pads 29 carried by the pistons of cylinders 11, the cylinders being carried by table 10 mounted to rotate about stationary shaft 1. The suction is led to its suction pad 29 from central shaft 2 via pipe 13 valve 14 and pipe 17. The suction pads and cylinders 11 are mounted in pairs on the rotating table 10 so that two bricks are grasped from press table B at one time, the operation of the piston within each cylinder 11 causing each pad 29 to be moved down into engagement with a brick on table B. Table 10 is then driven by pin 21 mounted on plate 19 driven from the press table B. As table 10 moves through one step cylinder 11 is operated to cause each pad 29 to pivot under the restraint of a rod 39 such that each pair of bricks is laid on belt C with the bricks in axial alignment and having been rotated through 90 degrees. This movement is assisted by each pair of cylinders 11 being connected to a plate 30 which is moved inwards and outwards by cam 33 via two rollers 31, 32. Brake 47 serves to stabilize the off loader at each point when it is stationary. Belt C. Figs. 7 and 9.-Belt C is driven stepby-step by means of cylinder 51 operating via lever 55 and ratchet 56. Each pair of cylinders 11 of the off loader A deposits a pair of bricks as shown in Fig. 9 on belt C. The bricks are aligned relatively to the edges of the belt by plates 63 operated by cylinders 66, the plates and cylinders being carried by carriage 64 running on rails 65. The carriage is moved forward along the belt by means of cylinder 70 so that an end plate 68 engages the bricks and pushes them forward into engagement with the previous pair of bricks. The end plate 68 is also movable in vertical direction by means of cylinder 69. In this way the successive pairs of bricks are positioned so as to touch each other. Should the carriage 64 not move the predetermined amount forward to displace the bricks, then a switch is arranged to cause the belt to move forward an additional amount so as to compensate. Grab D. Figs. 1 and 2.-The bricks fed by belt C are engaged by fingers carried by the grab. The grab D is carried by carriage 89 running on rails 90 which permit the grab to be displaced along the rails so that the bricks can be loaded on to trolley E for further treatment. Switches permit the bricks to be built up on trolley E in pyramid shape for ease of entry into an oven. Fingers 80 of grab D. Fig. 10.-Each finger 80 of the grab is pivoted at 83. It is caused to engage a brick in pairs by means of rubber tube 85 which is expanded pneumatically against the influence of spring 84.

Title: Improvements in and relating to key cases
IPC: A45C11/32
Filed: 1947-09-30
Abstract: 657,615. Key-holders. BUXTON, Inc. Sept. 30, 1947, No. 26397. Convention date, Oct. 18, 1946. [Class 44] In a flexible key case Fig. 1, comprising a back panel 4 and two flaps 5 provided with the usual fasteners 6, the keys being suspended from hangers 2 whose enlarged heads are engaged in slots in a tubular supporting member, the slots have enlarged escape openings which are normally blocked by having within the tubular member a resiliently mounted bar, one end of which has a finger grip extending outwardly from the end of the tube and is movable to unblock the openings. The hanger support, formed from a blank as in Fig. 2, consists of a plate portion 7 and bar 8 connected by spaced members 9 which define slots 10 having the escape openings 11. Blocking fingers 16 extending from the bar 8 are aligned with the escape openings 11, and finger grip forming portions 13, 14, are formed respectively on an extension 12 of the bar 8 and on the opposite side of the plate 7. The upper portion is rolled downwardly as in Fig. 5 so that the bar 8 lies against plate 7, the fingers 16 covering the openings 11 and the finger pieces 13, 14, are bent outwardly at right angles to the bar 8 and plate 7 respectively. On pressure being applied as by thumb and forefinger to the finger pieces 13, 14, the bar member and finger 16 are moved against the resilience of members 9 to uncover the openings 11 and allow insertion or removal of hangers 2 which have enlarged heads. When a hanger of the type described in Specification 657,664 is inserted into an opening 11, the plane surface of its head being against the finger 16 as in Fig. 8, an anticlockwise rotation will cam back the blocking finger 16 without using the finger pieces 13,14. The latter are always employed, however, for removal of the hanger. In a modification, the plate 7 is shortened and is attached to the key case by prongs provided on the plate. In a further modification, Fig. 16, the bar and blocking fingers are formed separately from the plate and slotted cylinder, the bar having an extension 28 bent at right angles thereto, provided with a hole through which passes a tongue 36 at right angles to, and formed from, the finger piece 35. A spring 40 housed on the tongue 36 normally maintains a tongue 30 on the bar against a tongue 37 on the cylinder. In another embodiment Fig. 18, the bar 8 is wider and no fingers 16 are provided. On pressing the finger grips 47, 48, an outwardly directed cam tongue 49 on the bar engages the adjacent end of the tube, an inwardly directed cam tongue 50 carried by the plate is engaged by the bar, and the bar is forced inwardly to uncover the escape openings. A key hanger is described in which a piece of spring wire has its ends forming a shank portion terminating in enlarged heads of hemispherical shape having the flat face adjacent the shank.

Title: Arrangements for the generation of vibrations for testint  torsional vibration behaviour
IPC: G01M7/00
Filed: 1973-06-05
Abstract: 1423630 Torsion testing ELBE-WERK ROSSLAU VEB 5 June 1973 [20 July 1972] 26752/73 Heading G1S [Also in Division H2]  An arrangement for the generation of vibrations for testing the torsional vibration behaviour of parts comprises a rotatable shaft having at an end thereof means for carrying a part to be subjected to torsional vibration, the shaft being driven by the rotor of an electric motor, an element connected to the shaft to produce a constant load torque on the motor and an exciter unit to electrically load the rotor in a time-variable manner to cause rotor load torque variations about a mean value set by the element, the variations resulting in a torsional vibration imposed on the rotary motion of the rotor and the part-carrying means. The motor may be a series-wound, shunt-wound or squirrel-cage motor or, as shown in the Figure, a slip-ring induction motor 4 having at its shaft end 7 an induction brake 3 to produce the constant load torque and at its shaft end 7' a shaft part 1 having a mounting flange 6 to receive parts (not shown) to be tested for their behaviour under torsional vibration. The ends 7, 7' are mounted by bearings in pendulum fashion, whereby the motor stator can swing as a unit about its central axis which is also the axis of the motor rotor. The stator winding is connected to A.C. mains voltage or to an adjustable A.C. voltage. The rotor voltage is passed by slip-rings 8 to a rectifier in the exciter unit 2 having thyristors T 1, T2 controlling resistors R1, R2 for loading the rotor, the thyristors being controlled by a pulse generator 5 which determines the time periods for which the resistors Rl, R2 are connected to the output of the rectifier. Hence a variation in loading is produced on the rotor, about a mean value predetermined by the brake 3, which variation manifests itself as a torsional vibration transmitted to the part to be tested via members 1, 6. A further pulse generator (not shown) may be associated with the generator 5. Shaft part 1 may be omitted and flange 6 connected to the end 7', Fig.2 (not shown).
