DYNAMO WITH REGULATOR CUTOUT GD 1915 MOTOR WITH STARTING SWITCH GRAY & DAVIS STARTING-LIGHTING SYSTEM A Remarkable Advance in Electrical Equipment A Gray & Davis dynamo and starting motor of the 1915 type are shown above. The system as installed in different makes of cars varies somewhat to meet different specifications — but all installations are patterned after this general type. The Magnet Type of Frame You will notice that these units have a rectangular or magnet-shaped frame. This frame is constructed of one flat piece of low carbon steel formed into a U shape. A piece of the same quality of steel is bolted across the end. This innovation gives the following distinct advantages: (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 developed. (4) Bearings are mounted in accurate alignment. (5) Field pieces are absolutely true. (6) The number of parts is materially reduced. Accessibility A notable feature of the 1915 type is its ready accessibility. By unscrewing the side plates, the interior is open for inspection or adjustment. Lubrication Convenient oiling places allow the lubricant to flow readily to all bearings. Voltage Our experience in building dynamos and motors has shown that 6 volts is the logical and economical pressure for automobile equipment. We do not require 12, 18, or 24 volts, as is the case with some systems. A 6-volt battery means a genuine saving in battery weight, space, and maintenance cost. We require but a small 3-cell battery, the same as that used for ignition. Furthermore, the Gray & Davis dynamo and starting motor are designed to conserve the life and strength of the battery — a most important factor in the consideration of any electric system. Wiring The method of mounting the regulatorcutout and switch leads to a distinct reduction and simplification of wiring. We will be glad to supply complete data on request. Any detailed questions will be fully answered by special letter. GRAY & DAVIS, Inc., Boston, Mass. 321 SCRIBNER'S MAGAZINE ADVERTISER

Such fidelity of tone was unknown before the advent of the Victrola—the first cabinet style talking-machine; and this pure and life like tone is exclusively a Victrola feature.
