The West Side Y.M.C.A. Airplane School Notebook from 1918

191840619New York: Y.M.C.A. Training School 1918. Octavo. Three ring notebook filled with unlined loose-leaf paper. Handwritten notes made by unknown author. Date on first notes paper is Sept. 7th - 1918. The student who kept this notebook included many drawings of implements and mechanical parts of airplanes. Also included in the notebook is "the Compound Nozzle Explained" a short 14 pages pamphlet from 1915. The student punched holes and added it to his course notes. The notebook covers two courses: Airplane Motors with Professor Hall and Plane School with Mr. Chedester. In the back of the notebook there is a bibliography a list of tools needed to apply for positions in an airplane factory and a long list of questions the student recorded to ask after lectures. Several clippings from magazines or other sources are included throughout. The student who kept this notebook would have been well prepared for a career in the U.S. Air Service or in a factory. According to the U.S. Labor Department Training Bulletin see below a graduate of the Y.M.C.A. Airplane Mechanics School could expect to earn between $35 and $50 per week to start up from $12 per week in nonessential industry. The training program lasted for 5 weeks 6 days per week. There was also a night program that lasted for 10 weeks. "The West Side Y.M.C.A. Airplane School was established in November 1917 with the object to supply a crying need for men with some knowledge of airplanes both in the Air Service and in the factories. At that time the Government made a call for 10000 airplane mechanics who were urgently needed for this service. In all probability there were less than 1500 mechanics in the whole country who had any experience with airplanes in the field. The Y.M.C.A. embarked upon an extensive advertising program using newspapers magazines and billboards. The results were most gratifying as the school has always had a waiting list regardless of the increased floor space and additional capacity. Inquire for more details. Y.M.C.A.

Early Aviation Engineering: 1920s Handwritten Technical Manuscript on Aircraft Engine Ignition and Electrical Systems

1920127751920. Early aviation technical manuscript explaining aircraft engine operation ignition systems and electrical wiring during the formative decades of powered flight. Produced in the early 1920s when aviation technology was transitioning from experimental wartime aircraft to increasingly standardized civil and military aeronautical engineering the manuscript documents the mechanical knowledge required to operate and maintain contemporary aircraft engines and electrical systems. The notebook focuses particularly on ignition circuitry engine starting procedures and performance specifications subjects central to the reliability and safety of early aviation machinery. References to the Jaguar engine a widely used aircraft powerplant of the interwar period situate the manuscript within the technical environment of early twentieth century aviation engineering and aircraft maintenance training.<br /> <br /> Manuscript aviation engineering notebook. Fourteen handwritten pages with numerous technical drawings and labeled diagrams explaining aircraft systems. The manuscript includes sections describing "general data" relating to aircraft performance characteristics such as speed and weight along with detailed mechanical illustrations including a "main wiring diagram." Several pages explain engine starting procedures and ignition circuitry. One labeled sequence reads: "Jaguar starting. See that both the engine magnets are switched off and that the throttle is in the slow running position. 2. With gas starter. Connect the gas coupling of the starter to the lead to the distributor of one of the two engine magnets. See that H1 lead switch from gas starter mag to engine mag is switched off. 3. Start the gas starter." Another passage describing a technical diagram states: "The ignition system is a highly developed form of battery coil ignition designed as an integral part of the engine. The general layout comprises a direct current generated gear driven from the engine." The manuscript combines written explanation with hand drawn schematics intended to clarify the layout and function of aircraft electrical and ignition components.<br /> <br /> During the early 1920s aviation expanded rapidly following the technological acceleration of World War I when aircraft design engine power and onboard systems developed at unprecedented speed. Technical manuals and engineering notebooks such as this formed an essential part of the training culture surrounding aircraft mechanics pilots and aeronautical engineers who needed to understand increasingly complex electrical systems ignition mechanisms and engine starting procedures. The attention given to wiring diagrams and ignition circuitry reflects the growing sophistication of aircraft power plants and onboard electrical networks during the interwar period. Surviving manuscript documentation of this kind provides insight into how aviation technology was taught recorded and transmitted during a period when aeronautical engineering was still developing standardized instructional literature. Light handling wear with minor age toning; overall excellent condition. A detailed early technical manuscript documenting the mechanical knowledge underlying inter war aviation technology. unknown

[AVIATION]. FRANKLIN, Paul J[ames].Biblio.com

Wonderful souvenir album chronicling the aircraft stunt flying and automobiles of a Salem Oregon flight instructor for Ryan Flying School with several aerial shots of air shows and airports.

193764225Salem OR: Paul J. Franklin Commercial Pilot Photographer 1937. Oblong 4to. 10.25 x 7 in. 24 pp unpaginated. With 15 original silver gelatin photographs sized from 2.5 x 3.5 in. all neatly mounted w/ tan paper corners 1 printed business card for Franklin mounted on front pastedown w/ corners. Simulated burgundy-coloured crocodile post-binder boards gilt lettering stamped on front c over punch-sewn at gutter margin w/ brown silk braid NF exemplar w/ all photos having nice contrast. A fascinating souvenir album chronicling the career of a young aviator test pilot and aerial photographer during the Great Depression while working as an instructor for the T.C. Ryan Flying School in Salem & Albany Oregon. The photos depict Franklin seated in the cockpit of a race plane; aerial view of the Salem Airport and other airports; image of a 1935 Waco YPF-6 Biplane crashed onto its belly with pontoons laying behind; trick flying including inverted shots and smoke writing a â€˜76â€ for Union 76 Gasoline. Along with an interior and exterior shot of a stylish streamlined Art Deco 1937 DeSoto the album concludes with a shot of Watsonville Airport in Santa Cruz CA with a Travel Air E-4000 biplane at the hangar entrance owned by D.M. Harwick with dirigible flying above the field. Franklin 1912-1957 was the son of longtime Salem dry cleaner owner Orie F. Franklin 1882-1960 and after Ryan Flying School became a C.A.A. flying instructor in Albany Oregon enlisted and served in the Navy during World War II recovered from a bout of malaria and following the War moved to California where he became a test pilot for North American Aviation jet aircraft until 1955. He subsequently became a Hollywood Stunt pilot working with Paul Mantz and is perhaps best remembered as having restored with his friend Coffin one of three Ryan B-1 aircraft substituted as Lindberghâ€™s Spirit of St. Louis and also doubled along with Mantz for James Stewart for some shots in the filming of the 1957 movie â€œThe Spirit of St. Louis.â€ Tragically he was subsequently killed after filming in an automobile accident along Pacific Highway.
