Mentioned in 1872 Manufacturer & Builder. Ads in 1891 Manufacturer & Builder (but ads are not viewable in the online archive because they were on journal covers, which were not preserved when the volumes were bound). This company made ventilation equipment, blowers, and woodworking equipment. James M. Seymour Jr. received an 1890 patent for a fan that was the first to use aerodynamically efficient blades that are widest in the middle and tapered at the ends.

- Ad in the September, 1890 of issue of Carpentry and Building magazine, showing their sash dovetailing machine.
- Correspondent Richard Saunders reported a Seymour & Whitlock "chopper" style miter trimmer. It sports an invalid "AUG 7 72" patent date; although we have looked, we have not found a miter-trimmer patent matching this example.
Journal of the Franklin Institute, Vol. LXIX, January-June 1875. No. 2, p. 98: Medals awarded at the Franklin Institute Exhibition: James M. Seymour, Newark, NJ. Sash dovetailing machine. Honorable mention
- Seymour & Whitlock were mentioned in 1872 and 1874 issues of Journal of the Franklin Institute, plus 1890, i.e., spanning the above reference to James M. Seymour, so probably James was exhibiting under his own name but manufacturing as a partnership.
- See patent 79,783 for a miter chopper granted to James M. Seymour and assigned to "Daniel Whetlock". Should be "Whitlock", of course.
