Title: Improvements in starting devices for internal combustion engines
IPC: F02N15/06
Filed: 1920-04-21
Abstract: 143,205. Dayton Engineering Laboratories Co., (Assignees of Chryst, W. A.). May 12, 1919, [Convention date]. Turning-gear.-In a starter for internalcombustion engines comprising an electric motor and a pinion adapted to engage an engine gear, a controlling member controls the starting of the electric motor and also controls mechanically the forward movement of the pinion, which in the event of obstruction of its engaging movement by the engine gear is set for rapid enmeshment prior to the rotation of the electric motor. In the form shown, the starter pinion 94 is slidably keyed upon a shaft 9U driven from the armature shaft 40 of the starting motor 30 through gears 80, 81 with helical teeth and a roller clutch 82. The pinion 94 is moved into engagement with an engine gear by means of a pedal 113 acting through a forked lever 110 and a grooved sleeve 97 connected to a shell 100, the end 101 of which engages a flange 95 on the pinion. The movement of the lever 110 and sleeve 97 is communicated to the pinion through a coil spring 103 bearing against the flange 95. The motor is a four-pole machine having a pair of brushes 50, 51, Fig. 4, connected to the field coils 39 and to the battery, one pole of which is earthed. The other brushes 56, 57 are earthed and are normally held away from the commutator. When the pedal 113 is depressed, the brushes 56, 57 are brought into contact with the commutator by means of a link 66, which has a cam surface 70 and slides in a slot 67 in the motor casing, a plunger 64 being interposed between the link 66 and an arm 63 on the brushcarrier 54. The other brush-carrier 55 is acted upon through arms 60, 61 and a plate 62. The armature is moved axially by the attraction of the field coils and the action of the helical gears 80, 81, and a cork braking-ring 43 on the armature shaft is thus moved out of contact with the end member of the motor casing.

Title: Improvements in or modification of safety means for the door of an elevator
IPC: E05B65/00
Filed: 1961-03-27
Abstract: 971,488. Safety devices for lift shaft doors. SCHWEIZERISCHE WAGONS-UND AUFZUGEFABRIK A.G. SCHLIEREN-ZURICH. March 27, 1961 [April 4, 1960], No. 11138/61. Addition to 876,371. Heading B8L. [Also in Division E2] The safety device for preventing movement of a lift unless the shaft doors are closed disclosed in the parent Specification is modified in that the means, including contactless switch elements, which is operated by the closing and/or locking of the shaft door to control the safety circuit of the lift motor comprises a body of magnetically saturable material provided with a winding and forming part of a magnetic system secured in the door, whereby the magnetic flux flowing over the locking bolt produces at least a partial saturation of the body, which modifies the resulting signal only when the bolt has locked the door. As shown, a lock casing 20 of non-magnetic material is secured to the door post 2 and contains a non-magnetic bushing 4 for locking bolt 23. An element for checking the position of the locking bolt comprising a ring core 33 and a winding 34 is secured between pole shoes 35, 36 on an angle piece 31 of magnetically conductive material which is secured to and extends through an opening 29 in the easing 20 so that it contacts the door post 2. In the door leaf 1, a magnetic system 40 is provided comprising an iron frame 41 to which are secured four anisotropic permanent magnets having their 8-poles contacting the frame and their N-poles contacting a magnetically conductive ring 46 through which the locking bolt 23 may pass. A further element 56 for checking the closing of the door leaf 1 and comprising a winding 60 is secured between pole shoes 58, 59 which touch, respectively, an angle piece 55, secured to an iron piece 54 mounted in openings in the casing 20 and in the door post 2, and an iron piece 61 welded to the angle piece 31. Opposite the iron piece 54, the door leaf 1 is provided with an opening 65 with a cover 66 housing an anisotropic permanent magnet 69 and an iron disc 68. In operation, on closing of the door, magnet 69 produces a magnetic flux which saturates the core 57 of element 56 so that A.C. applied to winding 60 may pass to influence the elevator control to actuate the lever 21 and thereby to lock the bolt 23, whereupon the magnetic system 40 saturates the core 33 allowing A.C. to pass in the winding 34 to influence the elevator control to allow the cabin to start its travel.

Title: Improvements relating to control systems for electrically-propelled vehicles
Inventor: WITHNELL ARTHUR CLIFFORD
IPC: A61G5/04
Filed: 1960-03-30
Abstract: 907,209. Control of D.C. motors. WITHNELL, A. C. March 28, 1961 [March 30, 1960], No. 11159/60. Addition to 836,900. Class 38 (3). The control system for the motor of a battery vehicle described in the parent Specification is modified to include a " dead man's handle." This comprises a biasedoff switch on the steering wheel or tiller, release of which causes the cutting off of power to the motor and preferably the application of rheostatic braking, at least when the vehicle is moving forwards. Mechanical wheel brakes may also be applied by an electrical actuator. As shown, release of the switch opens relay contacts DMH, de-energizing relay MPR, contacts on which are included in the energizing circuit of contactors R+ and RR. These contactors are in the motor supply circuit and two are used to minimize the chance of mal-operation through sticking. The motor supply is thus cut off, and further contacts on relay MPR, and also interlock contacts RRa on RR, close to energize rheostatic braking contactor B. Contactor R+ has auxiliary contacts R+a in the energizing circuit of the resistor contactors R2 ... R4 which are thus opened to prevent the rheostatic braking, e.g. from full speed, being too severe. Contactor R1 remains operable to allow two degrees of braking, according to speed conditions obtaining when the dead man's handle was released. The braking will be effected regardless of the direction of rotation of the motor, but a simpler circuit is described wherein rheostatic braking occurs automatically only if the motor was. running forwards. Upon re-closure of the dead man's handle switch the motor will not restart until the controller is returned to the zero speed position, since only then will relay MPR be energized. An overload cut-out OL has also been introduced in the present arrangement.

Abstract: 823,065. Stapling machines. OFREX Ltd. Aug. 16, 1957 [May 16, 1956], No 11523/56. Class 89(3) In a stapling tool, the guideway down which staples are driven by means of a driving blade is defined by a removable member held by a resilient latch and formed with a recess the depth of which determines the thickness of the guideway. In a pliers type stapling tool a removable member 21, Fig. 4, received at the front end of the magazine 2, Fig. 3, is provided on one side with a rectangular recess 45 adapted to form, with the front of the magazine bar, a guideway for thicker staples, and is provided on the other side with a recess 46 having stepped side parts 47 which form, with the front of the magazine bar, a guideway for thinner staples. The centre part of the recess 46 is of the same depth as the recess 45, and the driving blade 22 is of a cross-section corresponding to the recess 46. The member 21 is held resiliently in position by a projection on the inside of the magazine engaging a recess 42 in the member, enabling the guideway to be selected at will by the user. In a modification, Figs. 5 and 6 (not shown) the rectangular and stepped recesses may be formed respectively on separate removable members 21.
