Title: Improvements in and relating to snap-action mechanisms and electric switches
Inventor: CLEMENTS CYRIL ARTHUR JOHN
IPC: H01H13/28
Filed: 1956-06-08
Abstract: 812,433. Sliding bolts. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 1, 1957 [June 8, 1956; Nov. 15, 1956], Nos. 17737/56 and 34918/56. Class 44 [Also in Group XXXVII] A snap-action mechanism comprises an operating member moveable alternately, in opposite directions against the bias of a compression spring, and an operated member which is movable parallel to the operating member is oppositely biased against the compression spring and is held stationary relative to a base member during at least part of the operating movement by a ball or roller detent engaged between either the operated member and the base member or between the operated member and an intermediate member held stationary relative to the base member, the operating member having two spaced grooves or notches co-operable with the detents so that by movement of'the operating member the operated member is suddenly freed for movement to its other operated position. Figs. 2, 3 and 4 of the second Provisional Specification show a snap-action mechanism suitable for use as a mechanical lock. The mechanism comprises an inverted U- shaped base 1, a U-shaped actuating member 2, a U-shaped locking member 6 and an operated member 7 having the forms shown in Fig. 4 and assembled one within the other as shown in Fig. 3. The actuating member 2 carries a cam follower 2b which coacts with a cam 3, Fig. 2, driven by gearing from an electric motor 5 carried by the base. A compression spring (not shown) is seated in slots 6a, 7a in the member 6, 7. A roller 8 passes through slots 1a, 2a, 6c, 7c, in the members 1, 2, 6, 7 and a locking roller 9 passes through slot 1d, 6b, 7b in the members 1, 6, 7. In one rest position, the rollers are in the position shown in Fig. 4, the operated member 7 thus being locked to the base 1 by the pin 9. When the cam 3 is rotated to move the actuating member 2 to the right, the roller 8 is raised by the slot 1a to engage in the notch 6f of the slot 6c so that the locking member 6 is carried along with the actuating member 2 and the spring is compressed between the locking member and the operated member. Full travel of the actuating member to the right brings the roller 8 to the extreme right hand end of the slot 7c and the locking roller 9 to the notch 6d in the slot 6b into which it rises. This upward movement releases the roller 9 from the notch 7e of the slot 7b and allows the operated member 7 to be moved to the right by the spring until the roller 9 reaches the end of the slot 7b. This movement brings notch 7g in slot 7c under the roller 8 and allows the roller to move down thus releasing the locking member so that excess spring compression can move it to the left thus forcing the roller 9 into the notch 7d in the slot 7b and re-locking the operated member 7 to the base in its new position. Further rotation of the cam causes the above cycle of operations to be repeated and the operated member to move to the left.

Title: Improvements in and relating to methods of and apparatus for shaping silica
IPC: C03B23/055
Filed: 1928-06-23
Abstract: 292,624. British Thomson-Houston Co., Ltd., (Assignees of Hollnagel, H. P.). June 23, 1927, [Convention date]. Forming silicaglass objects. - A method of forming objects of silica consists in heating a mass of fused silica to a temperature ol' about 1400‹C., and then shaping it while plastic by the progressive application of localised pressure over its surface. A device for carrying out the process- .comprises a mandrel or mould 6 secured to the end of a spindle 1, both spindle and mould being bored axially. The spindle is journaled in bearings and is provided with pulley wheels, by which it is driven. In operation, a slug 8 of fused silica is inserted, in the axial bore, and the protruding head of the slug is heated to the required temperature by means of an oxy-gas burner 9. The spindle is set in rotation, and when the silica is plastic, it is forced to flow over the surface of the mould by the pressure of a tool 13 which is supported on a holder 14. The tool is moved in respect to the silica, so that a highly localised pressure is exerted, and the silica is caused to fiow or bend and to conform to the surface of the mould, the process thus resembling the spinning of metal. When completed, the article 17 is cut away from the rest of the silica, slug. The mould may be provided with'electric heating devices in order to prevent it from chilling the silica unduly.
