Dear Sirs,

Enclosed I beg to hand you advertising circular and loose sketch of a water cooling filter invented and placed upon the market by me, especially for radiators of motorcars and for water cooled combustion engines.

The construction is very simple and effective and seems to be extraordinarily suited for being applied in standard type to motorcars.

Perhaps the article may interest you, it is an accessory that will no doubt help to push the sale of new cars and at the same time it is a step forward to the perfection of the motorcar.

Here follows a description of the filter:

The filter chamber A is pressed in one piece.
B is a ring forced in one piece serving as a sediment chamber.
C is the filtering screen through which the cooling water flows and along which sediment is washed down into B.
D is the cover closing the apparatus.
E is the steel spring by which cover D is fastened.
The ring B can simultaneously be taken out with the screen C, so that it is possible to clean both screen and sediment chamber at the same time. Cleaning can be done within a few minutes.

The filter has been put into practice and has met drivers' satisfaction everywhere for more than a year. Should there be any interest on your side for this my patent for Great Britain and North Ireland I shall be pleased to receive your bid.

Further details if desired will be furnished on application.

Awaiting your news, I remain, Dear Sirs,

Yours Faithfully,
[Signature]
