This page is **not a cartoon or satirical content**—it is a straightforward **advertisement** for Gray & Davis electrical equipment, specifically their starting and lighting system for automobiles. The ad promotes their 1915 dynamo and starting motor as "A Remarkable Advance In Electrical Equipment," highlighting technical features like a shaped frame design, magnetic leakage prevention, and a 6-volt battery system. The company emphasizes durability, compactness, and reliability. Two mechanical components are illustrated at the bottom: the regulator-circuit integrated with dynamo (left) and the starting motor (right). This represents early automotive technology marketing rather than satire or political commentary. Gray & Davis, Inc. was a Boston-based manufacturer addressing practical automotive innovations of the era.

A Remarkable Advance In Electrical Equipment A Gray & Davis dynamo and starting motor of the 19135 type are shown at the bottom of this page. The system as installed in different akes of cars varies somewhat to meet different specifications—but all installa- tions are patterned after this general type. The units shown have a magnet- shaped frame, This innovation in frame construction es the following distinct advantages over other forms. of construction : (1) The frame is more rugged and will stand the most severe service. (2) It is more compact. (3) Magnetic leakage from the armature is avoided, thus conserving the full power doveloped. (4) Rearings are mounted in ac- curate alignment. (5) Field pieces are absolutely true. (6) The number of parts is mate- rially reduced. ‘data on request. At Another notable feature of our 19135 type is its ready accessibility, By un- screwing the side plates the interior is open for inspection and adjustment Our 6-volt battery means a genuine saving in weight. We require but a 3-cell battery, the same as that used tor ignition.
