An International Correspondence Schools-style instruction paper (Serial 492, Section 57) on setting up, adjusting and maintaining power looms in a mill weave room. It covers erecting looms, tying in warps, and setting the shed, harness cams, lease rods, warp line, picking cams, lug straps, pickers, binders, shuttles, protector and filling stop-motions, temples, and let-off and take-up motions. Later sections troubleshoot banging off, shuttles flying out, thin places, filling kinks and cut filling, and warp defects such as poorly sized yarn and knots, and close with the duties of the loom fixer. Two diagrams illustrate the warp line and shed.

An International Textbook Company instruction paper (Serial 493) on loom attachments for cam looms, covering undercams for three- to six-harness work. It explains how to construct cams for 3/1 and 2/2 twills and five-harness satin, the auxiliary shafts and gear calculations that set cam speed, and the harness-roll (strap-and-roller) arrangements. It also describes plain and tape selvage motions, side-cam motions, and continuous take-up motions, with many mechanical diagrams.

An International Correspondence Schools-style instruction paper (Serial 491, Section 56) explaining the construction and operation of the plain power loom, as used for cotton weaving in the early 1900s. It covers the three primary motions (shedding by cams, picking with the cone pick, beating up with the lay) and the auxiliary motions: let-offs (Bartlett and Morton), take-up, filling stop-motion, brake, temples, shuttle protector and loose reed. It ends with practical notes on loom drive, power requirements and calculations for take-up change gears and loom production. Illustrated with line drawings of mechanisms and cam constructions.

Instruction paper from the International Correspondence Schools on laboratory testing of raw silk, covering the winding test, the sizing tests (regular 450-meter, American 225-meter, conditioned and compound) and the cohesion test. It describes sampling, preparing and weighing skeins, computing breaks per 100,000 yards, range and average denier, and the machines used (winding frame, sizing reel, quadrant balance, cohesion-card winder and cohesion machine). It includes illustrated apparatus, sample laboratory record forms and certificates, grading tables, and a set of examination questions for students.

Part 3 of an International Correspondence Schools instruction paper on silk testing, covering additional tests for raw and thrown silk. It describes the serimeter test (breaking strength and evenness), the serigraph test (strength, elasticity, elongation), the gauge test for defects and cleanness, the twist test, the mirror test for evenness, and the measuring test for skein length. Each section explains the apparatus, sampling, procedure, laboratory record forms and testing-house certificates, with worked rules and examples. Examination questions are at the end.

An International Correspondence Schools-style instruction paper (Serial 486, Edition 1) on the construction, setting and adjustment of power cam-looms for woolen and worsted fabrics. It covers the principal motions (shedding, picking, beating up) and the auxiliary motions (let-off, take-up, filling stop-motion, protector motion, selvage motion, temples), with a section on loom production. Side-cam and under-cam shedding are described, including how to construct and set harness cams. It is illustrated with many mechanical line drawings and contains no weaving drafts.

An International Correspondence Schools–style instruction text (two parts, Serials 487A and 487B) on woolen and worsted fancy looms. Part 1 covers the Knowles fancy loom: head-motion, harness chains, box motion and box chains, picking, take-up, brake and selvage motions. Part 2 covers the Crompton fancy loom, including its shedding, chain cylinder, box motion, protector, filling stop-motion, let-off and selvage mechanisms. The text is mechanical, with many line drawings of loom parts and gearing, plus a few pattern and filling drafts.

An International Correspondence Schools instruction paper on fixing power looms in woolen and worsted mills. It covers the duties of the loom fixer, erecting and starting looms, putting in warps, and the adjustment and faults of the shedding, box, picking, binder, shuttle, take-up and let-off mechanisms. Later sections deal with troubleshooting problems such as banging off, flying shuttles, broken picker sticks, cut or kinky filling, thick and thin places, poor selvages and weak warps, with closing notes on oiling, cleaning and supplies.
