SPOKE PULLEY 400' FILM MAGAZINE - WEST
HOLLYWOOD
Mitchell Camera Corporation, 665 N.
Robertson Avenue, West Hollywood, California 1929- 1946
Spoke Pulley 400' Film Magazine for the Mitchell Standard
35mm motion picture camera.
Following
Mitchell's earlier magazines having 6-hole and 8-hole pulleys, this 10-spoke
pulley design emerged in the mid-to-late 1920's. Like the previous 6-hole
pulley design, this believed first version of the spoke pulley was held on by a
single set-screw, as seen on the magazine featured here:
Following
the single set-screw design, the pulley would be held to
the spindle shaft by a cap screw, the cap screw being retained by two smaller
screws. This was Mitchell's
last pulley design, found on their magazines until they closed their doors in
the late 1970's:

The
magazine was designed by John E. Leonard of Los Angeles, California, who also
designed the Mitchell Standard. Leonard,
who held over a dozen patents related to the Mitchell Camera, was granted
Patent No. 1,336,640 on April 13, 1920, having applied it on May 19, 1919:

This
patent number is cited on Mitchell's "acorn" shield:
Up
until 1946 when Mitchell began manufacturing in Glendale, California, model
numbers don't appear on their film magazines from the examples I've seen. This doesn't hold true for some other
Mitchell components built in West Hollywood, such as matte boxes and tripod
heads which have been seen with model numbers.
Probably
coinciding with the introduction of the spoke pulley, Mitchell's magazine
shells were now being produced from a single casting. This manner of
construction followed their earliest three-piece
magazines wherein the two circular film chambers were attached to a singular
base.
Also gone were the ribs (called
"rods" in the patent wording) that lined the film chambers and the
lid interiors to hold the film in line upon the spools. As with Mitchell's
earliest magazines, these first spoke pulley magazines have smoother, lightly
textured finishes. Later on, Mitchell's
magazines, cameras, viewfinders and matte boxes were generally characterized by
their accentuated black wrinkle finishes.
Other than the white enamel finishes found on Mitchell's government,
military or scientific-issued equipment, this black wrinkle finish is the one
seen most often today. The raised rims
on the lids now have wide serrated bands, along with four raised bars that were
cast into the lids to improve grip.
When
dating the manufacture of these magazines, it should be noted that pulleys
could have been changed out during repair, being replaced with those of a more
current design or an earlier style. The maker's tag (or the lack thereof) is
generally a better indicator of the period of manufacture. However, research conducted by others on
Mitchell's maker's tags regarding the transition of city
names from Los Angeles to West Hollywood, suggests that the change on the tags
occurred about 1933/1934. There
may be some merit to this given that the Los Angeles address continued to be
shown in Mitchell's catalog illustrations until at least November, 1937. This was well after
their move to West Hollywood in August, 1929, suggesting that maybe Mitchell
was in no hurry to update their name tags or their advertising to reflect the
new location. In 1946, Mitchell moved to Glendale, California and this is
the address seen on most surviving equipment.
With respect to Mitchell's cameras, it should also be
noted that cameras sent back to the factory for servicing, were in standard
practice, issued a new tag reflecting the current factory's address. As an example,
this is why Mitchell Standard No. 5 sold on April 8, 1922 and manufactured in
Los Angeles, has an acorn tag with the later West Hollywood address.
Mitchell's
cameras and equipment bearing the "West Hollywood" address are not
seen very often.
