Title: An improved latch for performing both a locking operation and an electrical switching operation
IPC: E05B45/12
Filed: 1943-07-22
Abstract: 568,630. Lift - gate fastenings. YOUNG, L. W. July 22, 1943, No. 11945. [Class 44] [Also in Group XXX] A fastening particularly adapted for gates of lifts and controlling electrical contacts in the liftoperating circuit comprises a pivoted hook-like catch 20 rocked into engagement with a fixed bolt 24 by the bolt entering a recess in the side of the casing 10 as the gate is closed, the catch carrying a contact which bridges a pair of fixed contacts when the catch is in engaged position, in which position it is held by a spring plunger 28, 30, the inclined nose of the plunger engaging the correspondingly inclined lower edge of the catch to give a wedging action. The catch and recess are arcuately shaped so that they thus fit snugly round the bolt and hold it firmly. Release is effected by withdrawal of the plunger by keyoperated or manual means. As shown, a lever 34 with handle 8 bears against the end of the plunger, retraction of which allows the bolt to rock the catch to release position when the gate is pulled towards open position. Either a part of plunger 28, or, as shown, a separate catch plunger 40, holds the catch in each of its extreme positons by engagement with suitably placed recesses such as 42, 44 formed in the catch. Plunger 28 is held retracted till the gate is closed by engagement with the righthand end of the catch after the latter has been rocked clockwise to release position. In a modification, lever 34 is extended so that its upper end, which is preferably eccentrically formed to give a cam wedging action, engages the lower edge of the catch to hold it in engagement, the plunger 28 in this form merely serving to bias the lever by engagement with the side thereof. The casing 10 is secured to the gate by bolts, not shown, passed through apertures 14 in the casing, the heads of the bolts resting within the casing and being hidden by a closure plate, not shown, secured by screws entering tapped holes 12. As shown, an insulated contact plate 48 on the catch bridges contacts 50, which may be spring plungers, respectively secured to the wires 54 of cable 56. In an alternative form block 48 is carried on a lever biassed to contact-breaking position by a spring plunger, and rocked into contact making position either directly by the upper edge of the catch or by suitable link connection with the catch. In a further form, an insulated knob carried by the catch is adapted to engage between a pair of blade-spring fixed contacts. In another form, block 48 is carried by a vertically guided sliding member which is raised and lowered by an arm on the catch. Specification 506,380 is referred to.

Title: A Triple Function Entrenching Tool having Two Integral Components made in One Piece.
Inventor: BEVERLEY ALBERT
IPC: A01B1/02
Filed: 1916-08-23
Abstract: 109,822. Beverley, A. Aug. 23, 1016. Picks.-An entrenching tool which may be arranged for use as a spade, shovel, pick, or hoe comprises a tool member formed on one side as a spade or shovel blade B and on the other as a pick C, and provided with a central boss A, in which two sockets are formed at right-angles to each other to take the handle G. For use as a pick or a hoe, the handle enters the one socket as shown, and, when arranged for use as a spade or shovel, the handle passes through the other socket a sufficient distance for the end of the handle, which is cut away to facilitate digging, to bear against the back of the blade B. The handle is locked in position by a spring X which expands after the boss A has passed over it. The sockets in the boss are, when rectangular in crosssection, made with two of their sides inclined for a short distance as shown. The sockets may however be cylindrical for part of their length and coned for the remainder. When the tool is being used as a spade, the pick point C is secured to the handle by an adjustable metal strap H.

Title: Improvements in or relating to apparatus for heating liquids
IPC: A47J31/053
Filed: 1948-05-03
Abstract: 642,809. Hot-water boilers. BEST PRODUCTS, Ltd., and BEST, F. L. May 3, 1948, No. 12097. [Class 64(i)] [Also in Group XI] Apparatus for heating liquids for example in coffee percolators, clothes washing machines and water storage tanks has a thermally insulating air space which is between the heating chamber and the bulk of the liquid and which is open at its lower end to the interior of the main liquid container. In an electrically-heated coffee percolator embodiment, Fig. 1, heat conduction from the chamber 12 with heating element 19 to water in the main container 10 is reduced by air space 17. Water in the chamber 12 is thus more rapidly heated and circulation improved. In Fig. 3 (not shown) a modification has an airjacket 26 around the delivery tube 25. Thermostatic control may be used but a separate switch may be fitted to enable the rate of heating to be manually reduced after the water has boiled.

Abstract: 529,837. Electron-multipliers. KOLSfERBRANDES, Ltd., SHANNON, D. S. B., and CHATTERJEA, P. K. April 22, 1939, No. 12126. [Class 39 (i)] To obtain increased emission from the secondary emitting electrode F it is impacted by two streams of primary electrons with differing velocities one or both of the streams being modulated. Two thermionic cathodes A1, A2, Fig. 1, are surrounded by screen and control grids, and separated by a shield G and are enclosed in an electrostatic guide D ; the cathodes are at different potentials so that there are two electron streams of different velocity passing through the grid anode E. The guide D, the shield G, the control and screen grids may be in two parts; rods or flat strips may act as the screen grids. A single filamentary cathode J, Fig. 5, with a shield G may supply the two streams, the potential fall along the cathode providing the necessary velocity difference. Deflecting plates may be used to change the direction of the electrons ; a filamentary cathode A, Fig. 8, may supply two streams-obtained by use of the shield G-to impact the electrode F. In a further form two cathodes separated by shields &c. have a continuous heating filament.
