DURABILITY.

Many times greater than wood. Ferodo Lining
is cheaper than wood or metal.

10 SPARKING.

Doubles your power at once. Gives con=
fidence—your men wind faster and you

get more coal every hour of the day. Ferodo fabrics engage sweetly and

save jerk on ropes—gives instant power. Keeps the drum path smooth
and unworn. No need to use reverse steam.

THINK I

London Motor Busses and Tube Railways for several years
entirely depend on Ferodo lined brakes, and they carry

800 million persons safely per annum.

[COPY].	From 1 HE STAVELEY COAL & IRON CO. LTD.

Yorkshire Main Colliery, Edlington, nr. Doncaster.
Gentlemen,	September 4th, 1911.

The “ Ferodo ” Brake Lining in use here on our Winding Engine Drums gives every satisfaction.

The pits are over 900 yards deep, hoppit loaded weighs nearly 4 tons, winding rope 5 tons ; this load is
entirely unbalanced.

The brake is our four post type, with 9 ft. of bearing surface on each post, and is a foot brake.

Previous t using “ Feroo'o ” we used poplar brake blocks 8 in. by 5 in., the life of a set being about 5 weeks.

“ Ferodo ” brake lining 8in. by j in. has on four of the posts been in wear six months and looks like
lasting six more. The other four posts »ere changed after five months’service, having worn down in one
place to |in thickness with the holding power unimpaired.

The winding engine drivers speak most highly of its holding qualities, and there is no charring as with
wood blocks.	Yours faithfully, (Signed) S. CLARKE, Enginewrigiit.
