[2][4] Arbuckle served in Company B of the 15 Militia Regiment called by Governor Andrew Curtin under the threat of a Confederate invasion in 1862 during the Civil War.

[4] He returned to the grocery business and they renamed the company to Arbuckles & Co. when the brothers' uncle died in 1865.

[2][4] In 1868, Arbuckle patented a formula for an egg-based glaze that coated coffee beans, protecting them from the air.

[3] He invented a machine with a machinist and draftsman to fill, weigh, seal, and label the bags in one continuous operation.

They included premium coupons in their packaged coffee, which allowed them to get a secondary revenue source in other goods, like handkerchiefs, curtains, and razors.

Arbuckle developed and patented a machine that automatically filled and sealed sugar bags.

Havemeyer bought a controlling interest in Woolson Spice Company of Toledo, Ohio, Arbuckle's main competition in the coffee industry.

The charge was for using egg and sugar glaze to increase the weight and inferiority of the coffee product.

The trial was held in Toledo, and Harvey W. Wiley, chief chemist of the U.S. Department of Agriculture, was used as a witness.

They claimed no knowledge of the arrangement, but agreed to pay the U.S. Department of the Treasury US$695,573 (equivalent to about $25,474,700 in 2023), a sum representing shortage of duties for the last ten years.

[7][8] Arbuckle built a retirement colony for older citizens and a hotel in Lake Mohonk.

In 1901, he established the Arbuckle Deep Sea Hotel off the shore of New York City to help low income workers.

[1] Arbuckle married Mary Alice Kerr, daughter of William Herr, the former mayor of Pittsburgh.

[11][13] The Community House in Allegheny City was gifted by Arbuckle's sisters as a living memorial to the family.
