Begins with the principle of leverage, and shows the windlass, the early wooden toothed wheels used in raising water for irrigation; then shows how the water mill and the windmill, used for grinding grain, needed gears to change the direction of the power generated "With the coming of steam power, gears were needed for machines. The epicyclic gear and the involute curve are explained as well as methods of casting, grinding and lubricating modern gears." Georgia "Striking. Elucidates, with the aid of animated diagrams and closeups of movement, the mysteries of the lever and the geared wheel, and their use as magnifiers of power in machinery driven by wind, water and steam," Lambert's "Films in School" fi 621.83 Gears PLAIN INDEXING AND CUTTING A SPUR J GEAR.

Demonstrates varying degrees of friction. "Shows primitive means of transporting loads by dragging, then by cart, and early lubrication using tallow, animal fats, or crude asphalt on rude wooden bearings. "Demonstrates operation of a shaft turning in dry bearing. Shows various types of oil for different uses. "Tells the story of lubrication in the terms of use in six main classes: 1. Spindle oils to lubricate machinery with high speed but little pressure. 2. Internal combustion engine oils for different types of engines. 3. Gear oils for the many types and shapes of gears. 4. Steam cylinder lubricants to withstand extremely high temperatures. 5. Greases for extremely heavy-duty, slow-moving machines. 6. Machine tool lubricants used to aid in the cutting of metals by conditioning tools and materials that are being cut."

The film begins with a series of simple demonstrations explaining rolling, solid and fluid friction. Cohesion between solids and adhesion between solids and liquids are illustrated, and lubrication is defined as the process of substituting fluid friction for solid friction. Solid friction is further explained in greatly enlarged views representing two surfaces in contact. "Following scenes mention the viscosity of lubricants. "A cut-away automobile engine reveals the working of the valves and pistons. The use of an oil cushion in the bearings and the working of the piston rings are shown in animation. Oils of excessively low and high viscosities are contrasted, and their defects noted. Next the film explains how lubricants are supplied to the points in the engine where they are needed. "The hand pump and the splash systems are shown in the early cars in which they were used. . . The pump-and-splash system and the full-pressure system, both in modern use, are explained by diagrams. Several types of oil pumps are shown. "A very good film for use in shop courses in automotive mechanics and for driving instruction classes; should be valuable also in general science and physics classes, at the Junior high through adult levels. Advertising is entirely unobjectionable. Technical production is good in all respects." Don White in Educational screen "An excellent picture with a minimum of advertising." A. J.
