[201] & [202]. Long link flat suspension chains.

[203]. Gib and cotter attachment for long link flat suspension chains.

[Larger plate.]

[204] & [205]. Drive chains. See Ewart’s patent, No. 2752-76, and others. These chains are replacing belts for many purposes, as they give a positive drive, do not stretch so much, and last longer, besides which they are easily detached at any point, and a damaged link can be readily replaced.

[206] & [207]. Thrust chains, with friction rollers at each junction, used in hydraulic multiplying cylinder gear in some cases.

[208]. Ewart and Dodge’s patent chain, with renewable seatings between the links.
