Abstract: 506,831. Apparatus for testing fuelinjection pumps. HARTRIDGE, L. Nov. 4, 1937, No. 30292. [Class 102 (i)] In an apparatus for testing the output of fuel-injection pumps, troughs 39 are arranged adjacent each pump delivery and are tilted so that the fuel is directed into measuring flasks during a predetermined number of revolutions of the pump. The pump drive is connected to a shaft 4 which drives the-disc 3 through reduction gearing. The handle 25 is moved to extend spring 22 and change the position of the end 27 of the spring 26 so that when the projection 5 engages the cam surface 6, and the lever 11 is depressed, the rod 16 moves to the recess 46, and movement of the lever 11 by the spring 45 causes rocking of the lever 29 which is connected by rod 34 to the troughs 39. The fuel is delivered to the flasks. The handle 25 is released and returns to its original position and when the projection 5 again engages the surface 6, the rod 16 moves to the recess 48 and under the spring 45 moves the member 29 to cause fuel to be returned to the sump. The pump may be driven by a variable speed gear as described in Specification 464,331, [Group XXIV].

Shielding member 4 is pivoted at 5 and is coupled by a spring 7 to a coupling lever 6 also pivoted at 5. An operative plate 9, also pivoted at 5, is coupled by a spring 11 to lever 6 and has a bent portion 9b which engages the side of lever 6. A free arm of plate 9 has a cam groove 9a formed therein, an eccentrically mounted pin 10a fixed to a self timer charge lever 10 slides within the groove and rotates plate 9 upon charging of lever 10. A stop lever 12 carries a plate 15 on one arm for engaging a plate 8 attached to lever 6 and a bent portion 12b on the other arm for engaging self-timer button 16. Movement of member 4 is also controlled by a snap-over spring and lever mechanism 17, 19 having a manual operating button 17', a projection 17b mounted thereon co-operating with a pin 21 mounted upon a mirror frame 3' so that member 4 can be returned from a shielding position by levers 6, 9 at the end of the delayed action period, the mirror action either on its upward or downward movement moving pin 20 out of engagement with member 4. The mechanism is used Fig. 4 (not shown), in conjunction with a shutter timing circuit which stores a signal representative of scene illumination immediately prior to mirror movement, and the shielding mechanism ensures that during the measuring phase when the delayed action self-timer is used the shielding member 4 is in a shielding position, whilst after exposure member 4 is restored to a non-shielding position.

In one embodiment, the surface 2 is placed on a platform 1 positioned horizontally, followed by a polythene foil 3 held on by a vacuum applied through the surface 2, steel reinforcement 4, and by an upper surface 5 (which may support the reinforcement by hooks or magnets). The platform 1 is tilted to a slanting position (as in Fig. 6) and concrete 6 cast and vibrated. The platform 1 is tilted to the vertical, an airtight cover attached, and vibration and suction applied through the moulding surface 5. The platform 1 is tilted to slant again, upper surface 5 removed, a foil 9 (Fig. 15) and reinforcement 10 applied, upper surface 5 reattached, and casting repeated. These steps are repeated until a stack of elements are formed, and then removed from the horizontally positioned platform by means of surfaces 5 or 2, with the aid of vacuum, atmospheric or positive pressure. Excess water can be sucked out at any time in the cycle.
