X-Ray Film Cassettes

The photo to the right shows an X-ray film cassette produced by the Buck X-Ograph Company of St. Louis, MO.

It is made of stainless steel with a bakelite plate on the front side (not shown). Needless to say, the front is made of a low atomic number material so as not to attenuate the X-rays.

The cassette identifies the dates of two patents: 1-1-29 and 4-9-35. Based on those dates, I would suspect that it was manufactured sometime around 1940 or so.

The image above left shows the back side of a stainless steel Rigidform cassette produced by Halsey X-Ray Products Inc. of Brooklyn New York. A red sticker in the lower right corner, dated 5/5/69, refers to the DuPont Cronex X-ray Screen. The front plate, not shown, is made of bakelite. The opened cassette is shown above right. The patent, number 2298587, was granted October 13, 1942. This, and the red sticker suggests that the cassette itself probably dates from the 1950s.

The above photos show a Wafer Rigidform cassette produced by Halsey X-Ray Products Inc. of Brooklyn New York. The body and front plate both seem to be made of aluminuml. The patents (2298587 and 2878389) date from October 13, 1942 and March 17, 1959 respectively. The cassette itself might therefore date from the 1960s or 1970s.

Size: ca. 10.5" x 10.5," designed for 9.5" x 9.5" film
