Title: Improvements in electric switches
IPC: H01H21/42
Filed: 1926-06-11
Abstract: 276,460. Norton, L. J., and Hansford, S. June 11, 1926. Switches, quick-action.-In an electric switch. of the type comprising a pivoted contact-arm operatively connected to an actuating lever, a spring or springs being provided for obtaining quick-action, the actuating lever has a fulcrum or bearing upon a spring-controlled movable member which is moved, by angular movement of the actuating lever, to energize the controlling spring or springs to give the quick-action when the lever moves over the dead-centre with respect to the contact-arm. In the construction shown the contact-arm 1 is carried on a fixed pivot 2 and is pivoted at 4 to an actuating lever 5 formed with two trunnions 6, one on each side, which engage vertical slots 7 in a pair of parallel plates 8 guided for ,horizontal movement within a casing 3. The plates 8 are connected to the casing by springs 10. When the lever is raised, it turns for the first part of its movement about the point 4, the trunnions 6 causing the plates 8 to move outwards thereby tensioning the springs 10, the contact-arm remaining unmoved. When the trunnions 6 reach the upper ends of the slots 7 the lever 5 turns upon the trunnions as centre thus positively moving the contact-arm, the slotted plates 8 continuing to move outwards until the dead-centre is passed when the tensioned springs give a quick break. The plates 8 are guided in the casing 3 by projecting pins 9. which carry one end of the springs 10, engaging slots 12 in the casing. In a modification the plates 8 are provided with recesses in lieu of closed slots. One spring only may be used and compression springs may be employed in place of the tension springs 10.

Filed: 1970-03-26
Abstract: 1307710 Draughting machines MACHINEFABRIEK L TE STRAKE NV 26 March 1970 [31 March 1969] 14887/70 Heading G1X A device for converting a plan view drawing into a perspective view drawing comprises a guide rod 21 pivotally supported at 20 relative to a base-plate 18 and pivotally mounted relative to a vizier means 32 movable over the baseplate 18, the guide rod 21 being provided with a marking device 22. In use, a plan view drawing is mounted on the base-plate such that the pivot support 20 for the rod 21 is located vertically above a point on the drawing from which the vizier means 32 is moved so as to coincide successively with a plurality of selected points on the plan view. In accordance with the vertical height of objects at these selected points the vertical height of the pivot point of the rod 21 to the vizier means 32 is positioned proportionately so that the marking device 22 will assume, for each selected point on the plan view drawing, a position, relative to a board 25, which is in accordance with both the position of the selected point on the plan view and the height of an object at such point. The marking device 22 which may be a pneumatically operated stylus will therefore produce on a paper attached to the board 25 marks providing a perspective view as would be seen by an observer when located at the selected position indicated by a vizier device 23 on the plan view. The guide rod 21 is universally jointed to a structure 19 at one end of the base-plate 18 and passes through an eye 38 connected to a clampable member 35 which is positionable along vertical rods 34a, 34b connected to a base member 33, the base member 33 defining a vizier and being slideable along horizontal guide rods 30 which themselves are jointly slideable along further guide rods 27a, 27b. A dial gauge 41 and blocks 39 eccentrically mounted on a rod 40 are used to set the vertical position of the guide rod 21 at the vizier 33. Instead of a single guide rod 21 a plurality of inter-connected rods may be employed Fig. 7 (not shown).

Abstract: 996,534. Friction clutches; electromagnetic disc brakes. EATON MANUFACTURING CO. April 16, 1963 [May 14, 1962], No. l4953/63. Headings F2C and F2E. Gap adjusting means, for a clutch or a brake, comprises a ring member 51 carried in a recess 50 in one engaging member 13 and having yieldable gripping connection in an axial direction with the support 22 for the member 13, spring means 53 associating with the ring member 51 to resist engaging movement and to effect axial sliding of the ring 51 above a predetermined loading. In one embodiment, Fig. 1, the air gap 15 between a friction surface 39, carried between polepieces 27, 28 surrounding an energizing coil 34 and carried by a hub 18, and an armature 13 splined to a hub 22 is maintained by a ring member 51. The ring 51 is of frusto-conical section and has internally projecting teeth 55 engaging the crests of splines 47 on the hub 22 with a predetermined loading. A double helical circlip 52 with axially projecting spring fingers 53a acts on the ring 51 to urge the member 13 to the declutched condition in which the, ring 51 abuts the end wall 58 of the recess 50. On energization the member 13 moves axially and the spring compresses. Should the air gap have increased above the desired value the spring 53 moves the ring axially along the hub 22 against the engagement of the teeth 55 with the spline crests. On de-energization of the coil 34, the spring 53 acts on the ring 51 to move the armature 13 away by the desired air gap. In a second embodiment, Fig. 14, a pressure fluid operated clutch piston 99 is retracted by a predetermined amount from a friction facing 94 by a similar spring 116. The spring and ring may be modified such that the spring member is carried by, or forms part of the ring member, or the spring may abut the end of the recess in the member 13, the other end of the recess being formed by a plain double helical circlip. Reference has been directed by the Comptroller to Specifications 905,229 and 905,230.

Title: Improvements in automatic stop mechanism for circular knitting machines
IPC: D04B35/10
Filed: 1924-06-25
Abstract: 239,629. Billson, F., and Stirland, C. S. June 25, 1924. Stop-motions.-The breakage or excessive tension of a yarn or the occurrence of a hole in the fabric made on a multi-feed machine with a rotary needle-cylinder causes a universally jointed arm J to drop between the teeth H' of a continuously rotating wheel. The arm J thus moved about a vertical point J<1> comes into contact with an abutment F<2> and moves a slide F to the left. A cam rise F<1> on the slide then passes under a spring- pressed vertically sliding catch E which thus releases a slide C to which the machine starting lever A is provided. A spring D completes the movement necessary for stopping the machine. This movement re-sets the arm J bv the action of a cam N carried on the slide C and the movement of the arm J permits a spring W to re-set the slide F. The arm J is held out of engagement with the teeth H<1> during normal running by an arm L<1> on the armature of an electromagnet which is excited, when a yarn breaks, by the fall of the corresponding yarn, guide arm R, Fig. 3, which causes a cam Q' to turn until contact is made with a spring P and an electrical circuit is completed. The same result is obtained when a spring plunger f mounted in a member e depending from a swing arm d engages a hole in the fabric g. The arm d and a vertical shaft c on which it is mounted are swung round to a position where a circuit can be completed to excite the magnet. Each yarn passes over a light spring supported arm which is pulled down by excessive tension to release the yarn, the machine being then stopped in the same way as when a yarn is broken.
