By 1860 Almond & White—a partnership of David Almond and William White—was manufacturing mortising machines, hand lathes, presses, and drill presses. By 1866 the business was operating as D. Almond. Eventually Almond specialized in hat-making machinery and his other products were dropped.

Burr fur former of all sizes, section blowers, fur-cutting and chopping machines, etc., and also as making a leading specialty of pickers of all sizes, made to order. His manufactory is supplied with a full provision of all necessary machinery and furnishes steady employment to a force of ten skilled and experienced workmen. In the branch of mechanics pursued by Mr. Almond not only a high degree of skill is requisite, but considerable machinery adapted and devised for special uses. The principal articles manufactured here are the invention of the proprietor and have met with great and universal favor with hat manufacturers, to whose special uses they are adapted as being the most simple, perfect, and easily operated machines and appliances ever invented for the purpose. The trade of the house is large and influential throughout the country. Mr. Almond has resided in Newark since 1853."
