Abstract: 1442774 Relay contact arrangements E HALLER & CO 12 Oct 1973 [22 May 1973] 47771/73 Heading H1N A switch contact arrangement for use in electrical relays which must support high transient switching currents comprises three contacts, a first b and a second c are connected to a common point V and arranged so that a moving third contact a when it actuates makes contact first with the first contact b and on continuing its actuating movement causes subsequent contact between all three contacts, the first contact being connected via a resistance R to the common point V. Thus switching current flows initially via resistance R and subsequently bypasses it when the resistance is shorted out when all three contacts are touching. In an alternative embodiment, Fig. 2, not shown, contacts a and b are transposed. The contacts may be made of silver cadmium oxide and the resistor associated with contact b may be provided by making the contact mounting of resistive material.

Rack 10 may be moved into its working position, engaging the latches, after withdrawal of the press head but before unstacking, to allow plates to separate slightly before being latched in position. Plates may each have two latches engaging two racks on a level with the plate supporting rollers (17) (Fig. 3, not shown), and the latches of each plate are shifted between their locking and unlocking positions by a lever 4 pivoted on the same axis 2 as the latches and carrying abutments 5, 6 which engage the latches with some lost motion. Plates are unstacked by members 11 carried on an endless conveyor and so shaped as to be held in a raised position until reaching the front plate of the stack and then dropping to engage and pivot lever 4, thus releasing the latches 3, 9 of the front plate and moving it forwards. When the front plate reaches a plate previously unstacked (Fig. 2, not shown) a pin (16') on the latter engages lever 4 and pushes it back so that latches 3, 9 re-engage the racks. The racks are lifted to release the latches before the press head doses. The latches and levers are so weighted as to be stable in either end position (Figs. 4, 5, not shown). Racks 10 need not have a tooth for every plate, one tooth for every second or third plate being adequate to prevent groups of plates being moved far in unison.

The carrier 1 is mounted on a guide lever 16 pivoted to the shear frame at 17 and is slidably mounted in rectilinear guides 2a, 9a; the carrier 2 is slidably engaged in a rocker lever 14 pivoted to the shear frame at 17. A lower arm 14a of the lever 14 constitutes the carrier 6 and the carrier 5 is fixed. The arm 14a rests on a resilient buffer 20 and carries a removable abutment member 19 with its upper face flush with the upper face of the knife 8. When all four knives are present, e.g. for cutting I beams, initial downward movement of the upper knives by crank drive 9-12 brings them into contact with a workpiece supported on the lower knives and further movement of carrier 2 causes the rocker lever to rock and an inclined cut to be made. When the knife 8 is omitted, e.g. for cutting channel sections the abutment member 19 is provided to cause the rocker lever to rock. When only knives 4 and 7 are to be used, e.g. for cutting L-, round or rectangular section profiles, the abutment member 19 is replaced by one with its surface beneath the upper surface of the knife 7 so that a vertical cut is made. Springs 18 connect the carriers 1 and 2 to allow relative movement between the carriers. Figs. 3-6 show alternative mounting of the carriers in the shear frame. The cutting edge of the knives is shaped according to the profile to be sheared.
