Item #1013

Jas. H. Matheson of Reading, Pennsylvania produced a 9-page essay which outlined “Improvements in Gas Equalizers and Soot Collectors for Gas Producers” in the year 1921, with figures and photographs.

This essay directly addressed an article by W.B. Chapman, entitled “Fuel Saving in Modern Gas Producers and Industrial Furnaces” which had appeared in the Nov. 1921 issue of American Society of Mechanical Engineers. The article is attached in this compilation.

The purpose of Matheson’s writing is to affirm Mr. Chapman’s arguments in favor of the use of additional equipment to increase efficiency and savings with gas-heated homes. In addition to the suitable accessories put forth for by Mr. Chapman, Matheson outlines the success of the Gas Equalizer and Soot Collector in use at the Tube Works of Reading Iron Co.

Beside the pair of essays are six figures that make visible the form and function of the machines. Immediately before the essay is a letter addressed to Mr. M.A. Good of New Jersey (likely an editor of the journal), dated Dec. 22, 1921. Mr. Matheson’s has also included notebook memos regarding interviews of several companies interested in the acquisition of soot catchers, from Pennsylvania, Delaware, and New Jersey. On the cover are two photographs of gas equalizers and soot collectors (“one of which is shown on Figures No. 1, 2, & 3 herein illustrated”).

This material is fastened between two gray contraction paper pages, held together by brass fasteners. The essay is typewritten, and the pages are numbered. The memos are enclosed inside of an envelope.

In excellent overall condition. Slight silvering to photos on cover. Minimal edge wear apparent on pages, and one small tear at the bottom of a page.

Price: $150.00
