| Each Pump tested to 350 lbs. per square inch. The most Efficient Air Pump in the World. This is no idle boast, but an established fact that car-owners will testify to in every quarter of the globe. One tyre—one minute. It is an easy operation with the “Renrut Quadruple” because the patent action and wonderfully accurate construction make every ounce of power bring results. The Patent ‘Renrut’ QUADRUPLE TYRE PUMP The Turner Quadruple Tyre Pump is well made of brass—finished in lacquer and green enamel. Wearing parts have been reduced to a minimum by the introduction of metal valves wherever possible. It is equipped with a pressure gauge (regd.) having neither glass nor delicate parts, and which cannot be damaged by overpressure. One Size only. Dimensions : Length over all, closed, 20½ inches. Diameter of main barrel, 1⅝ inches. Weight 4½ lbs. The Turner Pump is fully guaranteed for twelve months. It will actually work for many years. All parts being standardised, replacements can be obtained quickly in case of damage by accident. Price with Gauge, 49/6 Price without Gauge, 44/- works on a quadruple compression principle, the main barrel of the Pump being double acting and drawing in air at both the up and down stroke, and so rendering the total capacity of the Pump almost double that of the large barrel. For this reason the TURNER QUADRUPLE although smaller in diameter than many other pumps, gives far more air per stroke. The actual power required to operate this pump, delivering such a large quantity of air at each stroke, has been reduced to a minimum by the introduction of a small high-pressure cylinder into which the large volume is first compressed. The ease with which a cylinder is operated is directly proportionate to its size or area, i.e., where a large cylinder would require a weight of 40 lbs. on the top of the piston, a cylinder one quarter of the size would only require a weight of 10 lbs. to obtain the same pressure at the outlet. The whole of the volume in this instance is concentrated beneath the small piston, so that almost double the capacity of the large barrel is forced into the tyre on each down stroke with the ease of operating a small cylinder. The “Renrut” No. 2 Single Action Pump. Price with Gauge, 17/6 Price without Gauge, 12/6 In this model we have met the need for a moderately priced pump that will yet give sturdy and continuous service. It combines the following features:—Barrel 20” by 1¼”—detachable handle, folding feet, best 3-ply rubber hose and strong solid drawn brass tube. We must direct particular attention to the fact that although this pump is so inexpensive there is nothing cheap about it—it has not been made merely to sell. It is a quality job throughout, strongly built from solid castings—not pressings. Nothing has been spared to make it a high grade pump worthy of the best car. The “Renrut” No. 6 Single Action Pump. This is a similar model to our No. 2 Pump—save that instead of Folding Feet, a strong malleable iron Stirrup Foot is bolted on to a Solid Brass Casting. It possesses that same capacity for sturdy wear and lasting service that marks every kind of pump we make. Price with Gauge, 17/6 Price without Gauge, 12/6 | ||
