Spencer Delineascopes and
Accessories
No date
This booklet measures 9 1/4" x 6" and
has 100 pages. The booklet is basically a catalog for Spencer Lens Co.
Spencer products included microscopes, microtomes,
delineascopes and their accessories along with other scientific instruments.
This catalog was produced most likely in the early 1920s. The catalog was
printed by the Roycroft and has their logo on a rear page but my picture was to
poor to post. A delineascope was an early movie projector.
The Roycroft also did up another booklet for
Spencer called Success in
Practice. Neither of these booklets are listed in McKenna.
Spencer History:
American Optical was established in 1833 as a small spectacle manufacturing
concern in Southbridge, Massachusetts. The company grew rapidly, gradually
acquiring additional facilities for manufacturing a range of optical products.
In 1935 this expansion lead to its purchasing the Spencer Lens Company of
Buffalo, New York (see below). For several years after the acquisition the
Spencer Lens Company continued operation under its own name before becoming
known as the Instrument Division of American Optical Company in 1945.
In
1982 Reichert partnered with AO, by that time a part of the Warner-Lambert
Group. The partnership used the name Reichert-Jung. They were bought by
Cambridge Instruments in 1986, which then purchased Bausch & Lomb's optical
systems division in 1987 (moving it to the former Spencer works in Buffalo),
using the name Cambridge instruments. Cambridge Instruments merged with Wild-Leitz
in 1990 to form Leica plc. Stereo microscopes continued to be manufactured at
the former Spencer works in Buffalo, sold first under the Cambridge and then the
Leica brand.
A Delineascope
This Spencer
Delineascope projected 3" by 4" slides by means of an interchangeable condensing
lens system. These projectors were used in large auditoriums as well as
traditional-size class rooms.
