John Hope had been making engraving drums for fabric printing as far back as 1780, by the time the House of Hope was established in 1810 in England, they was already the leader in the technology. The company expanded or moved to Rhode Island in 1847 under the care of the son, also John Hope, bringing their expertise to the thriving fabric mills of New England. John Hope (and later his sons) continued to develop engraving technology, perfecting pantographing technology, becoming the authority for all types of engraving, not just fabric. The company was finally incorporated in 1890 as John Hope & Sons Engraving and Manufacturing. From Grace's Guide. Googling the company name shows entries into the 1920s, but it's uncertain how long the company survived.
The small handout 3" scale above was an advertisement for their capabilities.
Below is a 1910 article from American Machinist reporting on the process. Pantograph patent here.
