at the base of the skirt.  The compression rings are prevented from rotation by means of stops.
    The gudgeon pins are of 5% case-hardening nickel steel, hardened and ground.  A special locking device is used to prevent both axial and rotational movements.

CONNECTION RODS.
    The connecting rods are "H" section of the "forked" type, made from 3½% nickel steel forgings, hea-treated to give a high Brinell, and machined all over to reduce weight variations.  A divided white-metal lined steel bush is gripped by the two caps of the forked rod, the ends of the bush being provided with external grooves which engage corresponding internal grooves formed in the forked rid.  The other rod is white-metal lined and works upon the center portion of the steel bush.  The small ends of both rods are fitted with "floating" phosphor bronze bushes.
