CHARGALYZER

Fast Battery Charger and Analyzer. Charges a battery in a car while the customer waits (30-60 minutes). Gives complete diagnosis of the battery in 30 seconds by accurate method of individual cell test. conclusive and convincing.

Meter indicates correct charging_time_ --- in minutes and correct current for each battery so that no damage to battery can occur. Automatic shut-off after set time. A complete battery department on wheels-a great time saver. Metallic rectifier type no bulbs, no moving parts except cooling fan.

LINCOLN "972” AIR-MOTOR-OPERATED LUBRIGUNS

The Lincoln "972" Single-Cylinder High-Pressure Lubrigun dispenses all types of lubricants-from viscous varieties to light cup grease- directly from the original container. The pumping unit is fully auto- matic and delivers lubricant under pressure on both upward and downward strokes. A container sleeve end cover of heavy-gauge steel, attached by thumbscrews to a rugged fourcaster truck, support the pump. The finish of the unit is baked white enamel. The base has a black enamel finish.

LINCOLN LUB-PAK

Lincoln Lub-Paks are hand-operated, 40-lb capacity fluid lubricant dispensers, which handle all types of gear lubricants and motor oils. The heavy gauge, electric seam-welded container and ruggedly built pump withstand hard service. An air-expellor, built into the pump proper, positively prevents pumping air with lubricant. The easily detached container top makes filling both fast and clean. Finish is baked white enamel.

Such features as accurate speed control, reduced_vibration throughout the speed range, and the necessity for lower Idling speeds have received particular atten- tion. Improvements have been effected on the widely used centrifugal and pneumatic types but each have certain inherent dis- advantages, which preclude them from being Ideally suitable to the G.I. engine. The solution to the problem of variable speed governing seems to have been successfully overcome through the development by British engineers of a direct acting-not relay type hydraulic governor.
