The old stamp mill, location unknown. A stamp mill (or stamp battery or stamping mill) is a type of mill machine that crushes material by pounding rather than grinding, either for further processing or for extraction of metallic ores. Breaking material down is a type of unit operation. A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft. On modern mills, the cam is arranged to lift the stamp from the side, so that it causes the stamp to rotate. This evens the wear on the shoe at the foot of the stamp. As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam. Each one frame and stamp set is sometimes called a "battery" or, confusingly, a "stamp" and mills are sometimes categorized by how many stamps they have, i.e. a "10 stamp mill" has 10 sets. They usually are arranged linearly, but when a mill is enlarged, a new line of them may be constructed rather than extending the line. Abandoned mill sites (as documented by industrial archaeologists) will usually have linear rows of foundation sets as their most prominent visible feature as the overall apparatus can exceed 20 feet in height, requiring large foundations. Stamps are usually arranged in sets of five. Some ore processing applications used large quantities of water so some stamp mills are located near natural or artificial bodies of water. For example, the Redridge Steel Dam was built to supply stamp mills with process water.
In this roundtable discussion video, members of Temple Beth Sholom discuss the history of the long-established congregation. Interviewees are Sandy Mallin, Oscar Goodman, Jared Shafer, Joel Goot, Arne Rosencrantz, Jerry Blut, Jackie Boiman, Gene Greenberg, and Flora Mason, with Shelley Berkley joining in later in the interview. Most of the interviewees have been involved in the leadership of the congregation. They discuss relationships with various rabbis over the years, and successful fundraising efforts to build the original synagogue. Other early leaders in the congregation were Edythe Katz-Yarchever, the Goot family, Stuart Mason, Herb Kaufman and Leo Wilner. Until the 1980s, Temple Beth Sholom was the only synagogue in Las Vegas, but after a dispute over the burial of a non-Jew, a new synagogue formed (Shareii Tefilla), and at nearly the same time, Temple Beth Sholom began investigating a move from their site on Oakey Boulevard. Most have nostalgia for the former location, but discuss the changes in the neighborhood that necessitated the move to Summerlin. Then they discuss the other initiatives that were borne out of Temple Beth Sholom, such as bond drives for Israel, B'nai B'rith, and the Kolod Center. They share other memories, and discuss the leadership and Sandy Mallin becoming the first female president of the temple. They credit Mallin with keeping the temple going through lean years, and helping to recruit Rabbi Felipe Goodman. The group goes on to mention other influential members of the Jewish community including Jack Entratter and Lloyd Katz, who helped integrate Las Vegas.
On March 18, 1978, collector Bill Hitchcock interviewed Della Coates (b. June 17th, 1919 in Birmingham, Alabama) at her home in Las Vegas, Nevada. In the interview, Della Coates discusses her time working for the telephone company. She also speaks about the changes in education and about changes throughout Las Vegas.
