Title: Improvements in electric switches
IPC: H01H71/50
Filed: 1922-02-27
Abstract: 200,044. Dobson, E. Feb. 27, 1922. Automatic circuit-breakers; switches, latching and unlatching.-An automatic oil-immersed circuit-breaker has bridging contacts h, h mounted on an insulating slab j and adapted to connect fixed contacts h<1>, h<1> passing through insulators g to terminals g<1>. The block j is secured to an operating rod t pivotally connected at u to an operating lever l pivoted at l<1> and to a parallel guide link k. A spring m extends between the pivot u and a spring-straining lever 2 loosely mounted on the operating spindle 4. Secured to this spindle is an arm 3 carrying pivotally at 6 a forked lever 5 within which is pivoted at 7 a hooked catch lever 8. At a second point 6<a> on the lever 3 is pivoted a trip lever 10, the upper end of which engages a. lateral projection 10<a> on the lever 8 so supporting it in its engaging position while the switch is closed (Fig. 1). A lever 11 is pivoted to the frame at 12 and provided with a lateral abutment 11<a> to co-operate with a similar abutment 5a at its side of the lever 5. To close the switch after it has been tripped (Fig. 2) the operating handle is first moved in an anti-clockwise direction carrying with it levers 3, 5, 8 and 10 until the nose 8<a> of the lever 8 engages a corresponding recess in the lever 2. To ensure this engagement a light spring 9 may be provided to overcome the gravitational effect of the rear portion of lever 8, which is reduced as the lever is tipped towards its vertical position. The handle is now moved in the opposite direction, the direction of pull on the various levers first causing the end of the lever 8 to be lowered on to the upper end of the lever 10, after which the spring is strained and its line of pull raised above the pivot l<1> until the weight and friction of the switch parts are overcome and the switch closes quickly, the lever l being held against a stop 2a on the lever 2 and the lever 5 being retained by cooperation of the inclined ends 11<a>, 5<a> of levers 5, 11. The line of pull of the spring m may alternatively be caused to cross the pivot l<1> in the manner described in Specification 166,592. The switch may be opened by movement of the handle in a clockwise direction the end of the lever 5 sliding upwards against the abutment 11<a> and by raising the pivot 7 of the lever 8 disengages its nose from the lever 2 allowing the spring m to force the abutment 2a against the lever l to cause a quick opening action. An overload release coil 20 is provided having a plunger 19 which on attraction rotates levers 16, 14 pivoted at 15 so moving the upper end of the lever 10 from the end 10<a> of the lever 8, the weight of this rotating it to disengage its nose from the lever 2. A dashpot 21 may be attached to the core 19. Alternatively a no-volt coil is employed (Figs. 3 and 4), the stop 23 on the rod 24 attached to the core 26 of the coil 25 rotating a pivoted bellcrank lever 22 to move aside the end of the lever 10.

IPC: F04B33/02
Abstract: 134,695. Dunlop Rubber Co., and Macbeth, C. Jan. 4, 1919. Piston pumps. - The object is to provide a simple construction of hand or electrically operated portable pump for use in garages for inflating pneumatic tyres, the pump also embodying features described in Specification 134,412. Fig. 2 shows an elevation and Fig. 3 the pump in plan, Fig. 4 showing the pump in section on the line 4, 4, Fig. 2, and Fig. 5 in detail the method of guiding the piston. Modifications in design appear in Figs. 7 and 8. The base D of approximately triangular shape in plan is formed with three points for normally supporting the pump. To facilitate transference, the base is provided with rollers D<4> and. the handle A<4> whereby the pump may be tilted and wheeled away. The upper part of the frame is socketed below so as to be carried by the pillar C which enters a socket D<1> on the base and is there secured by a screw D<3>. To the crank-handle, fly-wheel G, and crank His pivoted the pump-rod J, the lower end of which is forked so as to engage with the gudgeonpin K<4>. The ends of the pin pass through lugs upon the shallow piston K which is provided with a cup-leather and tightening-ring K<1>. The pin also supports the roller K<5> which runs with. in the pump cylinder and dispenses with the need of lubricating oil. The tray A<3> upon the frame serves to carry tyre-levers, &c. The part of the frame into which the cylinder B fits is formed with a valve-controlled passage to which the flexible tyre connexion may be attached as also the pressure gauge. The cylinder is not coaxial with the supporting pillar C but the centre of the fly-wheel rim G is in the same vertical plane that contains the axis of the pillar. The various parts lend themselves to ready removal, &c., for example, the cut-out portion B<3> of the cylinder allows the rod J to be withdrawn after the piston has been raised to its highest position and the gudgeon-pin removed. In the modification, Figs. 7 and 8, suitable for packing in a confined space for shipment, the cylinder B is formed in one with the frame and the fly-wheel G placed outside the frame, a crank serving to carry the pump-rod. Further, the tray is omitted and the handle A<4> formed of an inclined tube. In either example, power may be employed. For instance, electric motors L, Fig. 7, placed above or below and suitably connected to the pump may be fitted or if the pump is often used in one position the fly-wheel can be driven from an external powershaft. The supporting pillar C may be used as an air reservoir, and the pump automatically controlled through Switches to maintain a standard pressure.

The cam member 1 is mounted on a support 22 at one end of a spindle 6, the other end of which has a support 23 for carrying the workpiece 7. An intermediate part of the spindle carries a circular bearing plate 24 having its periphery disposed in a housing 25 formed with upper and lower pockets 26, 27 supplied with compressed air or liquid to floatingly support the plate. The inner surface 3 of the cam member 1 is engaged by the follower 2 which is mounted on a shaft 28 driven by a belt drive 31. The cam member 1 is urged towards the follower so as to engage it at the point 11 by guide follower wheels 13, 14 mounted on a spring-urged slide member (17, Fig. 4, not shown). The wheels 13, 14 are in upper and lower planes and engage respective tracks 15, 16 on the cam member so that as the cam member is rotated by frictional engagement with follower 2, the point 11 of contact therebetween remains in the plane P-1, the point of contact between the grinding wheel and the workpiece which is rotated with the cam member likewise staying in the same plane. The grinding wheel is rotated by a motor 35 and is carried by a slide 36 adjustable by a screw 32 to feed the grinding wheel towards the workpiece. The grinding wheel is axially reciprocated by a cam 42 driven by a motor 43, and an hydraulic cylinder 44 is provided for lifting the grinding wheel during loading of the workpiece. In another embodiment the cam member has a single track engaged by a single guide roller.

Abstract: 512,267. Dividing by fusion. LINDE AIR PRODUCTS CO. May 12, 1938, No. 14135. Convention date, May 29, 1937. [Class 83 (iv)] In a process of flame-cutting a metal plate &c. a high velocity oxidising jet 21, Figs. 1 and 2, (1,000 ft./sec.) disposed in a plane perpendicular to the surface P of the body being cut is moved relatively thereto to produce an irregular kerf 24 and at least one additional oxygen jet 22 is so directed as to plane or bevel at least one of the walls 25 of the kerf. The metal plate &c. may be previously preheated in a furnace or preheating jets may be arranged around the oxygen jets to raise the metal to the ignition temperature. The nozzles 27‹, 31 may be vertically arranged or they may be inclined to the surface, Fig. 3, at an angle of approximately 60 degrees.
