DETROIT, July 2.—I see in the issue of THE JOURNAL of June 30 a communication from the Shaw Valve Company, which is a plain misstatement of facts. A little more litigation on the part of the Shaw Valve Company and less bluff would be more in order. Enclosed find circular in reply to all this wind. Please insert it in your next issue, give me the same prominence as was given the Shaw Company.

ALVARADO MAYER, Inventor and Patentee of the Mayer Valve.

To Whom it May Concern :

The Shaw ReliefValve Company of Boston, having sent to all the users of my Relief Valves a circular by which that company claim that such Relief Valves are used without license, and that such valves are covered by certain patents owned by it, viz.:

Arthur M. Black, April 12, 1870. No. 101,814.

James Garland, November 14, 1871. No. 120,958.

Irven D. Shaw, January 26, 1875. No. 159,045.

Irven D. Shaw, August 3, 1880. No. 230,828.

In answer to such circular I would say that the valves now used by you, furnished by myself, are manufactured under certain patents issued to me at the following dates, viz. : December 31, 1872; February 4, 1873, and October 21, 1873. These patents antedate the Shaw patents, so that those patents are out of the way.

Lately I brought a suit against the city of Boston for infringing my patents by the use of the Shaw Valve. The Shaw Relief Valve Company were informed of the bringing of this suit and that it was necessary for that company to defend the suit; this it refused to do, and I obtained a decree against the city of Boston and the damages were paid. By allowing this suit to go against the city of Boston without defence, the Shaw Relief Valve Company admitted that the valves made under the Shaw patents were infringements of my patents.

As to the two other patents which they claim to own, I have had them carefully examined, and I can assure the users of my valve that those patents do not in any way anticipate my valves nor do my valves in the least infringe those patents.

If any action is brought against you for using any of my valves, as infringing any of the patents mentioned in the circular of the Shaw Relief Valve Company, I am prepared to defend it, and request prompt notice from you if you should be sued in any way.
