Terms
The compass is made of brass, glass, liquid, and metal. The compass is composed of a circular brass box containing a magnetic needle, which is designed to move freely around the circle that has been divided into 360 degrees. The needle and a brass bar are protected by a glass covering, and a pair of collapsible sights is located at the North-South axis of the compass. Compasses were typically mounted on tripods or staffs and rotated on a ball and socket joint. The Surveyor’s Compass is an instrument used to measure horizontal angles and for determining the magnetic bearing of a line sight. Surveyors would use this type of compass to help determine land lines, property boundaries, and other information useful to mapmaking, construction, and engineering.
This compass was distributed by A.S. Aloe and Company in St. Louis, Missouri, as indicated by the "A.S. Aloe & Co. St Louis" trademark on the face of the instrument.
A.S. Aloe and Company was founded by Albert Sidney Aloe in 1860 and by the early 1900s, it was the largest supplier of surveying, mathematical instruments, and allied goods in St. Louis. During the first twenty-five years of manufacturing, the company was also known as “Aloe & Hernstein” and “Aloe, Hernstein & Company”, but adopted “A.S. Aloe & Company” in 1885 and kept the name for 76 years and two generations of Aloes. The production of surveying equipment, however, ended in 1930 due to the Great Depression.
