Ismailia "Now you can let go, Koku," said Tom, for with the stooping of the motor the air pump ceased plunging, and there was no danger of it tearing loose. Tom Swift and His Great Searchlight; or, on the border for Uncle Sam The air pump is set within the condenser, and is wrought by a rod which is fixed to the piston and derives its motion therefrom. A Catechism of the Steam Engine The man again worked the instrument which was like a small air pump, taking care not to get his own face too near it. Tom Swift in the Caves of Ice, or, the Wreck of the Airship The great air pump was set going and soon from the after tube, a big stream of the compressed vapor rushed. Five Thousand Miles Underground Or, the Mystery of the Centre of the Earth A.--The air pump, which is set in the centre of the condenser, is 15-1/4 inches in diameter, and has a stroke of 11 inches. A Catechism of the Steam Engine In this passage the inlet and outlet valves at each end of the air pump are situated, and appropriate doors are formed above them to make them easily accessible. A Catechism of the Steam Engine This pump is called the air pump, because it also discharges any air which may have entered with the water. A Catechism of the Steam Engine A.--The air pump is made of brass 12-1/2 inches diameter and 42 inches stroke, and the metal of the barrel is 9/16ths of an inch thick. A Catechism of the Steam Engine Q.--Does the double acting air pump usual in direct acting screw engines, produce as good a vacuum as the single acting air pump usual in paddle engines? A Catechism of the Steam Engine The air pump connecting rod and cross head are shown in perspective in fig. A Catechism of the Steam Engine The air pump is double acting, and its piston or bucket has the same stroke as the piston of the engine. A Catechism of the Steam Engine The upper part of the air pump communicates with a small cistern S, called the hot well, through a valve opening outwards and called the delivery valve. A Catechism of the Steam Engine It consequently happens, that if there be the slightest leakage of air into the pump, this air is merely compressed, and not expelled, by the advance of the air pump piston. A Catechism of the Steam Engine A.--I put blocks of wood on the air pump piston, which at the end of its stroke projected between the valve plates and forced the water out. A Catechism of the Steam Engine Q.--Does the air pump rod move vertically as well as the piston rod? A Catechism of the Steam Engine The air pump rod is suspended from a cross head, passing from the centre of one of the links b d to the centre of the other link, on the opposite side of the beam. A Catechism of the Steam Engine The condenser and air pump are worked off the side levers by means of side rods and a cross head. A Catechism of the Steam Engine A.--It will do so if properly constructed; but I do not know of any case of a double acting air pump, with india rubber valves, which has been properly constructed. A Catechism of the Steam Engine A.--Metallic packing has in some instances been employed in air pump buckets, but its success has not been such as to lead to its further adoption. A Catechism of the Steam Engine Q.--The air pump, when double acting, has of course inlet and outlet valves at each end? A Catechism of the Steam Engine A.--The air pump bucket and valves are all of brass in modern marine engines, and the chamber of the pump is lined with copper, or made wholly of brass, whereby a single boring suffices. A Catechism of the Steam Engine Q.--Are air pumps now sometimes made double acting? A Catechism of the Steam Engine Q.--What species of packing is used in air pumps? A Catechism of the Steam Engine The air pump bucket derives its motion from an arm on the cross head, and a similar arm is usually employed in engines of this class to work the feed and bilge pumps. A Catechism of the Steam Engine If delivery valve seats be put in the mouth of the air pump at all, the best mode of fixing them appears to be that adopted by Messrs. Maudslay. A Catechism of the Steam Engine Q.--Are not air pump valves now very generally made of india rubber? A Catechism of the Steam Engine Q.--Will you describe the means by which the air pump rod is connected with the crank which works the air pump? A Catechism of the Steam Engine The trunk in the air pump enables guide rods to be dispensed with. A Catechism of the Steam Engine Q.--What is the difference between a single and a double acting air pump? A Catechism of the Steam Engine Q--What are the dimensions of the foot and discharge valves of the air pump? A Catechism of the Steam Engine The air pump rod is of brass, 2-1/2 inches diameter. A Catechism of the Steam Engine The air pump is bolted to one side of the bottom frame, and a passage is cast on it conducting from the condenser to the air pump. A Catechism of the Steam Engine The outlet passage leading from the air pump communicates with the waste water pipe, through which the water expelled by the air pump is discharged overboard. A Catechism of the Steam Engine Q.--Will you recapitulate the main particulars of the air pump? A Catechism of the Steam Engine To bore a brass air pump 36-1/2 inches in diameter requires a week, an iron one requires 48 hours, and a copper one 24 hours. A Catechism of the Steam Engine Double acting air pumps, valves of; faults of. A Catechism of the Steam Engine Q.--What are the details of the air pump? A Catechism of the Steam Engine In boring brass, the speed must be slower; the common rate at which the tool moves in boring brass air pumps is about 3 feet per minute. A Catechism of the Steam Engine Q.--Will you state the proper dimensions of the air pump and condenser in laud and marine engines? A Catechism of the Steam Engine Q.--You have stated that double acting air pumps need only be of half the size of single acting ones. A Catechism of the Steam Engine But in the double acting air pump no valve is required in the piston or bucket of the pump, and all that is necessary is an inlet and outlet valve at each end. A Catechism of the Steam Engine The air pump bucket is of brass, and the valve of the bucket is of the common pot lid or spindle kind. A Catechism of the Steam Engine The air pump is of that species which is called double-acting. A Catechism of the Steam Engine The speed proper for boring a cylinder will answer for boring the brass air pump of the same engine. A Catechism of the Steam Engine A brass air pump of 36-1/2 inches diameter requires the bar to make one turn in about three minutes, which is also the speed proper for a cylinder 60 inches in diameter. A Catechism of the Steam Engine Delivery valves in mouth of air pump, of india rubber. A Catechism of the Steam Engine Q.--What are the dimensions of the air pump? A Catechism of the Steam Engine Disc valves of india rubber for air pumps. A Catechism of the Steam Engine Valves, ball, Belidor's might be used for foot and delivery valves; butterfly, of air pump; concentric ring, for air pump bucket. A Catechism of the Steam Engine
