Fitzwilliam Sargent

Fitzwilliam Sargent was called the “father of brake-shoe engineering” and he obtained multiple patents for improvement of railroad brake shoes. He was born in 1859 in Philadelphia and attended Lehigh University where he graduated in 1879 with a Civil Engineering degree. He came to Mahwah (then Hohokus Township) in 1902 as the chief engineer of the American Brake Shoe and Foundry Company.

After joining American Brake Shoe, he built a large home on 5 acres off Olney Road. The house had all the latest improvements of the day, including electric lights and steam heat.

In 1935 the Board of Directors of American Brakeshoe built an up-to-date testing facility to keep up with the progress of the railroad industry.  The building was named the F.W. Sargent Laboratory Building and from the opening of the building to the date of his death at the age of 80 he went to work as often as possible.  The picture below shows his first invention, which he had done before he came to Brakeshoe, of a machine for testing brakeshoes.  During his career, he had many patents relating to the improvement of brakeshoes.  His last patent was issued to him in 1934 at age 75.    The invention created a system of reinforcing a brake shoe so that, if the body of the shoe broke, it could continue in service and not need to be replaced as quickly.
