The broad offering represents his familiarity with the trade and the needs of a growing western region. One instrument which Schmoltz recommended in his 1859 publication was an early form of surveyors transit in which the compass box is connected to the lower motion. With this instrument, when an angle is turned on the upper plate, the compass box is stationary with the lower motion.
Few examples exist.
In 1867 Schmoltz was granted a patent for the adaptation of William Burts' solar apparatus for use on a transit. Schmoltz should be recognized as an important west coast maker. His longevity in the market attests to his capacity to develop innovative designs, supply the needs of the people, and to successfully market his wares. Schmoltz continued in business until his death in 1891.
