1921 – After World War I, the company struggles financially as a global slow-down takes hold in most advanced nations. A voluntary receivership arranged with Thorvald S. Ross appointed by the bank to examine the business and provide recommendation for actions to take. Mr. Ross is overwhelmingly convinced the company still has more potential. He resigns from the bank and takes over management of the company as President.


1923 – The company reorganizes as The Rivett Lathe and Grinder Corporation.


1930s  Although the company survives the Depression, it is re-named Rivett Lathe & Grinder, Inc. to provide legal protection for the directors during uncertain times.

Four acres purchased nearby, and operations moved to a new modern-built facility in Brighton.


1966 – Rivett Lathe & Grinder, Inc. acquired by Applied Power Industries, Inc., Milwaukee, Wisconsin, and placed under management of its Dynex Division. The Dynex Division in Pewaukee, Wisconsin is already producing hydraulic products to serve both industrial and mobile fluid power markets.

1970 – The Rivett Division of Applied Power Industries, Inc. is primarily selling hydraulic power units, but is also now selling industrial hydraulic valves produced at another Applied Power facility located in Mineral Point, Wisconsin.


Demand for the Rivett brand of hydraulic valves is robust, and the Mineral Point operation is unable to keep up with demand. The Needham Heights operation begins to regularly purchase more than required for demand. Inventory of finished products increases to primarily sell to U.S. distributors who are requiring faster lead-times than achieved from either the Mineral Point or Pewaukee, Wisconsin facilities.

1981 – The Pewaukee facility expands its building to add more machinery and consolidate operations after closing a smaller facility that was operating out of a leased building in Mineral Point, Wisconsin. All Rivett product manufacturing operations at Mineral Point location move to the Pewaukee location.

1986 – Dynex/Rivett Inc. moves its New England operation from Needham Heights to Ashland, Massachusetts. This operation continues to design and fabricate hydraulic power units and warehouses finished goods manufactured by the Pewaukee operation. These stocked products provide shorter lead times for distributors and customers.

1987 – While the corporate name of the company remains as Dynex/Rivett Inc., Mr. Warell increases marketing and branding the use of the Dynex tradename over the Rivett tradename since it has greater customer recognition globally.
