[295]. Turned and finished link without any adjustments; ends may be solid, or forked as [No. 297].
[296]. Flat link of similar description, with raised bosses for facing and wear.
[297]. Adjustable link, with right and left hand screw coupling. Lock nuts may be added to prevent the coupling working back.
[298]. Strap link, fitted with brasses, gibs and cotters, and distance bar. In this link the wear of brasses is all taken up one way by the gib and cotter; therefore, if great accuracy in the distance apart of centres is necessary, gibs and cutters should be fitted at both sides of one pair of brasses, or [No. 299] adopted.
[299]. Turned link with adjustable end brasses. The forked end should be used where there is the greatest amount of wear.
[300]. Wood connecting- or pump-rod with wrought-iron strap ends, fitted with brasses, gibs, and cotters. Much used on mining pumps.
The shafts or rods are sometimes of cast iron of cross or T section, but are usually of a circular or flat section and swelled in the middle, similar to [No. 299]. See Struts and Ties, [Section 102].
[301]. The most usual form of shifting link for link-reversing gear, generally got up bright all over.
