The working arrangements on board the Olympic and Titanic are necessarily on a scale in keeping with the great size of the vessels. The number of crew employed on board each ship for all purposes is about 860. Of these about 65 belong to the navigating department, 320 are employed in the engineers’ department, and 475 are engaged in the stewards’ and catering department.

The forward portion of the boat deck and the exposed decks at the ends of the vessel are entirely devoted to working and navigating appliances, while the management of the ship is also greatly facilitated by the working passage on the port side of E deck, which extends nearly the full length of this deck and is connected by stairways with all the principal departments.

The steering gear is a versatile system located in the poop deck at the end of the shelter deck. It is of the well-known Wilson-Pirrie type, manufactured by Harland & Wolff.
This system consists of a spring quadrant and a tiller on the rudder head. Either of two sets of three-crank vertical steam engines can operate the gear independently, with the other serving as a backup. The gear is operated through a wheel-and-pinion and bevel gearing mechanism.

Figure 139 illustrates the entire arrangement. The engines feature inverted direct-acting cylinders, each with a diameter of 17 inches and a stroke length of 18 inches. They operate using steam at a pressure of 100 pounds per square inch.

Piston steam valves have been implemented and are directly driven from the crankshaft using eccentrics. Each engine's cylinders are supported at the front by three wrought steel columns and at the back by three cast-iron columns.

Two cast iron columns also support the intermediate shaft, which connects the spur and bevel gears. Each engine is mounted on a sliding bed with adjusting screws, allowing it to be quickly engaged or disengaged from the quadrant when switching from one engine to the other.

The crankshaft of each engine is provided with a spur-pinion which drives a spur wheel on the intermediate shaft, carried on the back columns of the engine. This intermediate shaft is connected by bevel gearing to a vertical shaft, a crucial connection that gears into the quadrant using a manganese bronze pinion above the bevel gearing. The role and significance of the bevel gearing in the engine system can be better understood by reference to Fig. 139 and the photograph of the engines given in Fig. 140.

The spur and bevel gear are of the Citroen type, a unique design made of cast steel throughout. They have machine-cut helical teeth of the herringbone shape. Experience has shown that this unique design is the most suitable form for minimum wear when the gears have to transmit power in either direction, as is the case with a steering engine. This is a testament to innovative engineering in the field.

The pitch is given approximately as the Citroen gears are not made to standard pitches. Their noiseless running is mainly obtained through a total absence of backlash, a crucial factor that ensures the smooth and efficient operation of the engine. This absence of backlash can only be achieved by calculating the exact pitch according to given diameters and a fixed number of teeth, which is why a special cutter is made for each set of gearing.

The sizes of the bevel wheels are:—pitch circle diameters, 5 feet 10½ inches and 2 feet 0½ inches; number of teeth, 19 and 55; pitch, about 4¼ inches; width of face, 11 inches. The teeth on both sides of the face are shrouded to the pitch line, and the total width over the shrouds is 14½ inches. Each bevel wheel weighs 1 ton 16 cwt, and each spur wheel weighs 1 ton 6 cwt. The spur pinion weighs about 5 cwt, and the bevel pinion weighs about 9 cwt. The quadrant and the pinion on the vertical shaft have machine-cut involute teeth.

Fig. 142: 15 1/2 Ton Center Anchor Pulled by Horse-Drawn Flatbed Trailer. The Shipbuilder, Midsummer 1911. GGA Image ID # 10e34dffbd

The center anchor, which is illustrated in Fig. 142, weighs 15½ tons, and the side anchors each weigh 7¾ tons. The cables connected with the side anchors are 3⅜ inches in diameter and have a total length of 330 fathoms, weighing 96 tons.

The anchors are of Hall’s latest improved type and, with the cables, have been manufactured by Messrs. N. Hingley & Sons, Ltd., of Netherton, Dudley.

A powerfully built crane is fitted at the center line of the forecastle deck for handling the 15½-ton anchor, which is placed in a well on the deck immediately above the stem. The side anchors are housed in the hawse pipes in the usual manner.

The lifeboats, which are 30 feet long, are placed on the boat deck, as shown in Plate IV. The davits are of the Welin double-acting type manufactured by the Welin Davit and Engineering Co., Ltd., of London. Sixteen sets, specially designed for handling two or, if desired, three boats each, have been provided.

The double-acting system is not altogether new, as it was adopted by another company some time ago in the case of boats carried on the poop. Still, its employment on such a large scale is a distinct departure.

The well-known principle of the Welin davit is retained in all its simplicity, with the addition of a slight segmental increase at the inboard edge of the quadrant. This modification enables the arm to be swung right inboard to plumb the inboard boat, thereby saving the time-wasting operation of shoving and pulling the latter into position, which has to be done with davits of the ordinary type.

The arrangement for saving fore and aft deck space is also worthy of notice. Instead of having two standards between each boat, the standards are combined as a twin frame; see Fig. 143. The latter carries the two quadrants and all the necessary gear for operating the forward and after the boat at will.

The operating gear is also of an ingenious and interesting nature. For this purpose, a single handle is employed, driving a small pinion mounted upon a swing bar. The latter is thrown into or out of gear using a simple eccentric arrangement, which enables either screw of either davit to be worked independently of the other.

Four 15-cwt electric winches, supplied by the Sunderland Forge and Engineering Co., have been provided in the positions shown in Plate III for hoisting and lowering the boats. The chapter on electrical equipment describes these winches.

The signals are received by small tanks containing microphones placed inside the vessel's hull on the port and starboard sides below the water level; see Fig. 144.

These tanks, which may be termed the ship's "ears," are connected to a direction indicator on the navigating bridge (Fig. 145) by ordinary telephonic cable.

By moving the switch on the indicator box to the port, only the port "ear" is in operation. By changing the switch to the starboard "ear," the starboard "ear" commences its work. Assuming the bell is on the port side of the ship, sounds are received only by that "ear."

Should the bell be dead ahead, the sound will be heard equally by both "ears." The signals, therefore, warn of the ship's proximity to the point of danger and assist her progress in a fog, as the navigating officer can tell with more certainty where the boat is located.

Accommodation for Officers and Crew

Plates III, IV, and V show the officers' accommodation. They are in a house on the boat deck forward.

The engineers' quarters are on the middle deck, and their mess room, pantries, offices, etc., are on the deck above, adjoining the working passage.

The firemen have excellent accommodation on five decks forward. Two spiral staircases and a tunnel through the forward hold access to their quarters to the boiler rooms, keeping them entirely clear of the passenger accommodation.

The seamen's accommodation is placed on E deck forward. The living rooms for the stewards and catering staff are situated on the port side of the E deck and are entered from the working passage.

Cargo, Baggage, and Mails

To provide access for cargo or baggage to the lower holds, three cargo hatchways, placed at the centerline of the ship, have been fitted forward for Nos. 1, 2, and 3 holds; four hatchways have been provided aft, two placed at the centerline for Nos. 5 and 6 holds; and two smaller hatchways, away from the centerline, give access to No. 4 hold.

The hatchways to Nos. 1 and 2 holds are served by three steam winches. The third hatch near the passengers' quarters is served by two 2½-ton electric cranes and two 3-ton electric winches.

The two hatchways to No. 4 hold are each served by a 14-ton electric crane. The remaining hatchways, Nos. 5 and 6, are each served by two 2½-ton cranes and one 3-ton electric winch.

The masts, which are 205 feet above the average draught line, are utilized for working the cargo using cargo spans. At the same time, the foremast supports a derrick suitable for lifting motor cars, which will be stored in one of the foreholds.

The post office and baggage accommodation are arranged compactly on the lower and orlop decks forward to expedite the reception and despatch of mail and the transportation of passengers' baggage on the ship's departure and arrival.

The Navigating Bridge

The navigating bridge, from which the vessel is controlled, is situated at the forward end of the boat deck so that the navigating officer may have a clear view ahead.

This bridge is a veritable forest of instruments. In the center is the wheelhouse, containing the telemotor control wheel by which the ship is steered, with a standard compass immediately in front. In front of the wheelhouse are the engine room, docking, steering telegraphs, and loud-speaking telephones to various stations.

The watertight door controller, the submarine signal receiver, the helm indicator, the master clocks, and other apparatus are also located in the adjoining bridge shelter or chart room.

A docking bridge is provided right aft for use when the vessel is docking or turning in a confined space.
