The Mounds Theatre Projection Booth 1029 Hudson Road Saint Paul, Minnesota Photos by Greg Cosimini Last Update: January 19, 2003

The projection booth contains two Simplex Regular projectors.  These probably date from the 1930s.  They haven't been used since the mid-1960s. Each projector has a Dowser Manufacturing Corp. automatic shutter control, Pat. No. 923042, serial numbers 5321 an 5322.

Here is a view from the other side. There is a small bathroom behind the wall on the left.

Although  it is hard to see here, each projector includes a RCA Photophone unit.

Here is a closeup of one of the bases.

Each projector has an Ashcraft Suprex carbon arc lamp. Their serial numbers are 1951 and 1952.

An interior shot of one of the lamp housings. There is still ash inside from the last time it was used, well over 30 years ago.

Each carbon arc lamp has its own rectifier.  They are BL Electrical Product Motion Picture Projector Rectifiers Type 76 made by the Benwood Linze Co.  Their serial numbers are 373 and 374.

Here is a Goldberg Brothers electric rewinder, HT Model B, Serial Number 3427X-49.  Under it, on top of the film storage containers, is a Griswold  Film Splicer Model R-2 No. 15524, distributed by Neumade Products Corp.  There is a price sticker on it for $3.50 from Ax Man Surplus, a local surplus store.  It was probably purchased in the early 1960s.
