dig so deeply into the bottom as to clog it or anchor the vessel that it must be completely under the control > GEAR SHEAVE \EQUALIZI Lraps TO WINCH of the operator as to the depth to which it is working. For this pur- pose it is suspended from the stern of the ship 'by wire ropes as shown in the drawing herewith. There are two TAE MARINE KEVIEW and returns to a sheave in the bracket and from there goes to one of the two drums of the winch which con- trols the depth of cut. Between the stern sheaves and the winch the ropes pass over the sheaves of an equalizer device which keeps the tension the same on each of them. The central winch is of a type inch enables one man to regulate the depth of cut with practically no physical exertion, to change the position of the cutter from moment to moment as may be required and to raise or lower the heavy head and suction pipe as he pleases. by the Lidgerwood Manufacturing Co., of New York, on purpose for this work. In effect it is a double side-by- side drum winch of the steering en- gine type. In fact, except for a differ- ence in the drums, it is almost a dupli- cate in design of the many tiny steering engines built by the Lidgerwood Man- ufacturing Co. for the United States torpedo boat destroyers except that it is of great size and power. It has the same compactness of design, relia- bility and ease of operation and high quality of material and workmanship called for in steering engine practice, and the control is through a hand wheel of equivalent type. The engine itself is controlled by a reverse valve system. By merely turning the con- trol wheel the operator raises or low- ers the cutter head as desired, the drums following closely the movement of the wheel and holding the weight of the head and suction pipe at any It was designed and built x WINCH of these ropes. One end of each rope is made fast to the ship. From there it passes over a. bracket at the stern, drops to a sheave on the cutter head AND ENGINE point where the wheel is left at rest. The engine has two upright cylin- ders each 12 in. in diameter by 12 in. stroke. To the crankshaft is coupled January, 1912 a Hindley worm made from a steel forging, which is provided with roller thrust bearings. The worm wheel is of bronze. There are two spirally grooved drums, made fast, one on either side of the worm wheel, on which the lifting ropes are coiled. The engine has a lifting power of 40,000 1b.---20,000 1b. on each drum--and it hoists at a speed of 50 ft. per minute. The winch is well shown in the ac- companying illustration made from a photograph taken in the Lidgerwood shops just after the engine was tested and officially inspected. Steam Trawlers Surf and. ~ Swell The steam trawlers Surf and Swell were launched on Dec. 9 from the yard of the Fore River Ship Building Co., Quincy, Mass.

On the main deck directly over the fish hold there is an ice crushing ma- chine through which about 10 tons of commercial blocks of ice can be fed into the hold, broken up into small pieces of a size best suited for the preservation and stowing of fish. The engine for running this ice crush- er is so arranged that it can be used for handling the cargo on arrival at the fish wharf. There is a turtle deck forward, and upon this deck is located the anchor- handling gear. On the main deck for- ward there is a steel deck containing lamp and paint rooms and entrances to the forecastle and cargo. On the quarter deck aft and embod- ied with the engine casing is another deck house of steel which contains quarters for two firemen and entrance to the cabins and engine room. In the forecastle are pipe berths and lockers for the accommodation of 14 men with a galley and mess room lo- cated just aft of the forecastle con- house
