Title: Improvements in and relating to sliding door fastenings
IPC: E05D15/06
Filed: 1936-10-29
Abstract: 483,682. Sliding door fastenings. OVERTON, W. Oct. 29, 1936, Nos. 29406/36 and 7637 /37. [Class 44] A sliding-door fastening, particularly for use on vehicles, comprises a hook catch g pivoted at h on the carriage e secured to the top edge of the door and biassed to engaging position by tension springs i. As described the catch is formed of laminations riveted together, an outer lamina having a square hook formation as shown in full lines at m, Fig. 2, the others having a contour providing a shorter hook nose with inclined leading faces, as in dotted lines. The outer lamina hook rests on the door-supporting rail d to support the nose of the remaining portion of the catch at a suitable height for ready engagement, and also is adapted to engage a projection 15 provided in rail d in which the rollers on carriage e run, to retain the door in open position, whilst the shorter-nosed hook is adapted to engage a projection n in the rail to hold the door closed. Two projections n are shown, to provide a safety catch, or a series of rack teeth may be provided to allow for different degrees of resilience in a buffer door edge where such is provided. The backs of projections n are inclined so that the catch automatically rides over them during closing movement. The catch is withdrawn by a T-member o the horizontal arms of which have slots respectively engaging fixed pivot pins p, q so that, whichever way member o is rocked, one pin forms a fixed fulcrum for one arm whilst the other arm rises, so raising the catch by engagement of an intermediate recess u in member o with a pin r carried by the catch. A fixed inclined ramp v above projections n serves positively to ensure engagement of the catch when the door is closed. The catch is controlled and the door moved by an inside handle 8 in the form of a tubular rod w pivoted at 7 and having telescopic engagement with member o. Operation from outside is effected by a cranked member y on the handle spindle engaging the lower end of rod w. A suitable connection between parts w, y is described comprising a fixed disc or fixed or pivoted ring on member y contacting slidably with the internal wall of rod w. A ball, also contacting with member w, may be disposed in the ring. The use of opposed springs for holding the outside handle in mid-position is also described. According to the first Provisional Specification a ball catch may be combined with the latch member to engage any one of a number of recesses in the rail to retain the door in open or intermediate position.

Title: Improvements in or relating to apparatus for preparing records for controlling the matrix selection in matrix-setting and type line-casting machines
IPC: B41B25/00
Filed: 1934-10-17
Abstract: 425,020. Type - making machines. TELETYPE CORPORATION, 1400, Wrightwood Avenue, Chicago, U.S.A.-(Assignees of Bracken, S. ; 507, North Spring Avenue, La Grange, and Goetz, M. T. ; 4400, North Winchester Avenue, Chicago, both in Illinois, U.S.A.) Oct. 17, 1934, No. 29696. Convention date, Nov. 17, 1933. [Class 100 (iii)] Strip - perforating machines; justifying type.- In machines of the kind described in Specification 420,084 for perforating record - strips for controlling type-line-casting machines, an auxiliary counting - mechanism is employed in order to increase the number of units recorded for each character by the matrixpointer by a constant amount of, say, 14 units, so as to permit of the use of a larger number of founts. To the driving- gear 46, Fig. 1, of the normal counting - mechanism, which operates the matrix-pointer 49 through a shaft 44, is secured an internal gear 52, Fig. 2. Loosely mounted on the shaft 44 is a ratchet-wheel 53 carrying a pair of planet-gears 54, 55, which mesh with the internal gear and also with a gear 56 fast on the shaft 44. The ratchet-wheel 53 is engaged by a pawl 57 carried by a lever 58, and also by a detent 59. An arm 65, pivoted to the lever 68, is connected by a lever 71 and a link 75 to a code-bar 61 in the selector-mechanism, so that the rising of the code-bar moves the arm 65 beneath an arm of the spacer-bail 78, which is operated by the spacer-cam 79 at each depression of a key-lever. The lever 58 is therefore depressed by the bail 78, and the ratchet-wheel 53 is rotated a step by the pawl 57, this motion being imparted to the shaft 44 and to the matrix-pointer in addition to the rotation they receive from the normal counting-mechanism. The lever 71 and arm 65 are connected by a spring so that another key may be depressed during the action of the auxiliary counting-mechanism. The codebar 61, which operates the auxiliary counting- device, is one of a pair of code-bars 61, 62, which are operated by projections 63 on slidable code-bars 13 carried by the key-levers. By a suitable arrangement of the projections on the code-bars 13, the auxiliary counting- device may be employed alone to advance the matrix-pointer through uniform distances.

Title: Improvements in or relating to battery charging apparatus
IPC: H02J7/04
Filed: 1956-10-02
Abstract: 839,875. Charging batteries. KAYE, E., SHARP, J. R., PAYNE, I. S., and ARNOT, A. E. R. Oct. 2, 1957 [Oct. 2, 1956], No. 30024/56. Class 38 (4). A battery charging apparatus, wherein a battery is charged from an alternating current source over a rectifier, comprises a device which enables the charging current to be maintained during the " gassing period and cut off a predetermined time after the " gassing period " has commenced. The device comprises a casing 10 which is lined with cork 12, a central hollow space in which houses a heavy metal block 13, the metal block being hollowed out to receive a bimetal switch unit 19 and a heating resistor 14. A space in the casing 10 above the cork lining 12 contains an electromagnetic relay 15. The battery is initially charged from an alternating current source 43 by way of a transformer T and a rectifier. When the battery attains a predetermined voltage and begins to " gas the relay 15 is energized sufficiently to close its contacts to supply the resistor 14 with current which then gradually heats the block 13. When the block 13 has acquired sufficient heat, that is, when the battery has " gassed " for a sufficient time the bimetal switch unit 19 operates to cut off the battery charging current. The length of the " gassing period " can be adjusted by variation of a resistor 16. The heating of the block 13 may be maintained once the bimetal switch unit 19 has operated by the provision of an auxiliary heating resistor 20 housed within the block 13. Alternatively the maintenance of heat in the block may be arranged by means of a high temperature coefficient resistor in series with the relay or by a resistor introduced, by a second bimetal switch, into a circuit in parallel to the relay or the main bimetal switch can be arranged to operate a relay controlling the auxiliary heating resistor. Switch 24 is a manually operable switch for connecting the A.C. supply directly to the transformer T when it is desired to dispense with the device 10.

Title: Method and apparatus for sub-dividing a length or angle
IPC: G01D5/244
Filed: 1955-10-20
Abstract: 817,594. Machine-tooldetails; indexing. WALDRICH G.m.b.H., H. A. Oct. 20, 1955 [Oct. 20, 1954], No. 30045/55. Class 83 (3). [Also in Group XX] An angle or length is sub-divided, particularly when performing a machinery-operation on a workpiece, by counting electronically the number of impulses in a sequence generated during the dividing-operation, until the total reaches the required fraction of a pre-arranged total representing the whole angle or length to be subdivided. Thus an angular subdivision may be effected on a workpiece carried on a table 1 rotatable by a motor 2 through a clutch 3 and gearing 6, 7. An electrical impulsegenerator 8 is driven from a gear-box 5, the pulses being counted by a counter 9 incorporating decade-tubes 10, until the total reaches that previously set on a pre-selector device 11. The motor 2 is then declutched or switched off automatically. It may be of the type automatically braked when switched-off. Any pulses generated during any " run-out " are included in the count for the next sub-division. A second pre-selector device 12 may be provided, the two devices being brought into operation alternately. The pre-selectors may be replaced by a device to which the required total of pulses is fed by punched cards. When the number of pulses corresponding to the exact subdivision required is not a whole number, successive subdivisions are effected by counting numbers slightly above and below the optimum, and chosen to give a total, for the whole angle, which is substantially correct.

Title: Improvements in or relating to electric control and/or indicating apparatus
IPC: G05D23/20
Filed: 1937-11-03
Abstract: 503,632. Electric signalling and control systems. BROWN INSTRUMENT CO. Nov. 3, 1937, No. 30165. Convention date, Jan. 9. [Class 40 (i)] [Also in Group XXXV] In an electric indicating, recording, or control system of the automatically balanced bridge type, balancing is effected by a motor under the control of a galvanometer pointer and two periodically operated members, one of which cooperates with the pointer to produce a variable control of the motor in one direction and the other co-operates with a fixed contact to produce a constant control effect for the motor in the reverse direction. The Figure shows a system for measuring the output of a thermocouple T connected in a Wheatstone bridge circuit comprising a galvanometer G and balancing resistance R operated by a motor M. The galvanometer pointer G<1> is periodically locked by a cam-operated frame G and pivoted arms GR, GF are oscillated under the control of springs GR<1>, GF<1> by a bar E<1>. The arms GR, GF co-operate respectively with the pointer G<1> and a fixed stop F located in a position corresponding to the zero position of the pointer and are connected in circuit with the reverse running field windings MR, MF of the motor. When the pointer is in the zero position, the arms GR, GF co-operate with the pointer and stop simultaneously to close the circuits of both windings and thereby stall the motor. Upon deflection of the pointer, however, one or other of the windings is energized for a period corresponding to the deflection prior to stalling to produce a corresponding control of the motor. An interrupter switch S is operated to open the circuits prior to the retraction of the arms GR, GF by the arm E<1> to prevent arcing. In modifications, instead of controlling the motor circuits directly by the arms GR, GF, the arms may carry enclosed switches of the mercury or pivoted contact type. In another modification especially adaptable to a strip chart type of recorder, the pointer is clamped periodically in a similar manner but its position is determined by the sloping edge of a feeler member which is raised periodically through lever mechanism into engagement with the clamped pointer. In a further modification adapted for measuring or controlling fluid flow, an automatically balanced inductance bridge is employed and the motor is operated by a double-triode valve, the grids of which are connected to the arms GR, GF. Instead of using a series motor, an induction motor of the shaded pole, squirrel cage, capacitor or split-phase type may be employed.

Abstract: 901,542. Yarn-winding machines. BARBERCOLMAN CO. Sept. 4, 1959, No. 30283/59. Class 120 (2). A machine for winding thread from successive bobbins is arranged to guide the running thread out of contact with a knotter whilst the thread from a reserve bobbin is held alongside the running thread in operative association with the knotter. The running thread extends from a bobbin 8a in a rotary magazine, through a notch 12 in a disc 9 fixed to the shaft 6 of the magazine. From the notch 12 the thread passes through a clearing device 13 and a break detector 15 to a driven tension reducer roller 19 which effects the breakage of weak threads as they pass through the detector 15. Between the end 53 of a guide slot 54 and an upper disc 22 fixed to the shaft 6, the thread passes in a straight line close to the knotter 25. Above disc 22 a loop 57 is formed that is instantaneously released upon operation of the break detector 15 to allow the thread length below the disc 22 to remain stationary during the period in which a knot is tied. A reserve thread from the bobbin 8b also passes through a cleaning device 13, then through a clamp 40 to slot 54 and a guide on the disc 22 from which it extends downwardly and is bent across and adjacent the running thread 48 and in contact with the knotter 25 from which it recrosses the running thread, passes within the severing area of a cutting device, has slack taken up by an arm 74 that holds a loop close to a suction tube 76, and has its end clamped at 43. On failure of the running thread, the shaft is indexed round to the extent of one magazine compartment, the running thread is temporarily clamped whilst the knotter and severing device operate, clamp 43 is released to allow waste thread to pass into the suction nozzle 76 and an arm 52 is operated to loop the fresh thread over the roller 19.
