16 MARINE REVIEW. [July 18, cantilever cranes and special cranes for ship yards and other works. For ship yards there are two systems of crane service constructed under the Seaver patents which the company controls exclusively. In general the principles involved in the Seaver system are the placing in position of two or more high-speed electric traveling cranes over the ways in which each ship is to be built, each crane being entirely independent of the other. In the ordinary type of service where one gantry crane 1s used over one or two berths the use of the crane for work on one side of the ship necessarily suspends work on all other parts where the crane is required, thus making apparent the advantage of having more than one crane avail- able. It is also apparent that there is a great waste of power in moving a heavy gantry crane to transport a light load only, and the Seaver system assumes the economy of using light, fast-running cranes designed only of sufficient capacity to carry a load of medium weight; in excep- tional cases where it may be necessary to handle a load beyond the capa- city of one crane, the lifting power of two cranes can be combined by an equalizing beam. The crane service of the Superior Ship Building Co., at West Superior, Wis., designed by this company, consists of an elevated steel track or runway extending the full length of the ship yard between two building berths, and mounted on this runway is a cantilever gantry crane which traverses the full length of the runway. By means of this arrangement the material is transferred from the end of the yard where it is delivered from the shops out to its place in the vessels with, a very small amount of handling and at great saving of labor. A point of interest in the construction of the crane is the double runway between which the wheels of the crane travel and by means of which the over- NEW WELLMAN-SEAVER PLANT. To sum it all up the Wellman-Seaver company are general engineers --civil, mechanical, mining and electrical. So far the company has been without a plant for its own use, but recently purchased six acres of land on the line of the Cleveland & Pittsburg Ry. at Giddings avenue, Cleve- land, and is now engaged in erecting a plant. There is one purpose underlying the construction of the new works and that is to produce a plant which will stand as a model of its kind. The plant will challenge inspection. It will be a concrete evidence of what the company can do for itself and therefore of what it can do for others. Representatives come from all parts of the world to visit the company and they will not fail to be impressed with the compactness, economy and completeness of the plant. It will have no altruistic features but will be a practical working institution. The drawings which accompany this article shows the gen- eral style of the buildings. It will doubtless be the pleasure of the Review at a later date to publish interior and exterior photographs of the plant. The machine shop will be a four-story brick building, 600 ft. long by 128 ft. wide. The first floor will be 70 ft. in the clear and will be so constructed as to admit an abundance of light to all parts of the building. No shafting, belting, pillars or other obstructions will be employed. Every machine will be driven by an individual motor. The pattern shop will be 165 ft. in length by 50 ft. in width, four stories high, and will be one of the finest pattern shops in the country. Its equipment of wood working tools willbe complete. Indeed the tool specifications for the entire plant are so elaborate that the tool makers to whom they were submitted ex- pressed surprise and declared that they had never read specifications so excellent and so thoroughly modern. The sum of $300,000 is being ad United States army transport Sedgwick. turning on the crane on the runway is prevented. The crane is 170 ft. in length from out to out of arms, 55 ft. high from top of rail to underside of crane, and has a lifting capacity of 15 tons half way out on the arms and 5 tons at the extreme end of the arms. This company has been retained as consulting and constructing en- gineers in connection with some of the most important blast furnace con- structions of the United States and Europe. It not only designs and superintends the construction of complete plants but makes a specialty of the designing and installation of the hoisting machinery for handling the stock. The Rombacher Huttenwerke, Rombach, Germany, was equipped with the Seaver blast furnace hoist designed by the company. The company is also the sole manufacturer of the Seaver electric coke unloader, designed to receive coke from the coking chambers of by- product coke ovens and load it into cars standing on adjoining tracks. The construction of this machine is such that it can traverse along the track in front of the coke ovens. The loading pan, after receiving the coke, can be lifted, first in a vertical direction and then out over the car into which the coke is to be loaded. The gates which form the front of the loading pan can then be opened and the coke dropped, without waste, directly from the pan into the car. The company also controls the Seaver patented coal elevator, designed for the rapid and economical handling of coal from vessels into storage pockets. It can also be arranged to handle other material of similar nature and the company is prepared to contract for the construction of complete coal handling plants, consisting of lifting and conveying machinery, storage pockets and weighing devices. It also constructs and installs cement manufacturing plants of the latest and most improved design. It recently designed a plant for the Iroquois Portland Cement Co., Caledonia, N. Y., now in process of construction. There isn't anything that this company will not undertake. The Cleveland Electric Railway Co. recently wanted loaded coal cars trans- ferred from the side track of a standard gauge railroad to the storage bins over the tops of the boilers in the boiler house. The company solved the problem by using a transfer table to convey the loaded coal cars from a side track to the elevator which raises the cars to tracks running over the coal storage bins and after dumping the coal lowers the empty cars to tracks in the cellar, running under the ash hoppers, permitting direct discharge into the cars, which can then be returned to the ground level. expended on tools alone. The boiler and power house combined measure 110 ft. in length by 50 ft. in width and will be two stories in height. A large dining room will be located over the power house. The forge shop will be 50 by 60 ft. The Sturtevant system of heating and ventilating will be employed throughout the plant and the instructions to the con. tractors are to provide the best possible for the comfort of the men. The sanitary arrangements will be of the most perfect order. The entire plant will be lighted with the arc and incandescent systems of electric lighting. No expense will be spared to provide everything which con- tributes to the welfare of the workmen. The plant will be healthful, well lighted and cleanly. It will be ready for occupancy about Nov. 1, and will employ from 600 to 1,000 men. : _This then is the Wellman-Seaver Engineering Co. which today maintains established offices in London and St, Petersburg and has resi- Ga ph eescentanives in Holland, France, Germany and Austria. Its sub- sidiary companies in Cleveland are the Electric Controll and the Balkwill Pattern Works. eee A WONDERFUL STORY. A wonderful story comes from Philadelphia to the effect that Andrew Carnegie has become interested in a device for propelling steamships invented by Lieut. James Weir Graydon, formerly of the United States navy, and that he is organizing a company with a capital of $4,000,000 to apply it. It is understood that the invention is a compound steam turbine bearing the same relation to the turbine invented by Charles A. Parsons at Glasgow that a simple engine does toa compound. Graydon's turbine according to the Philadelphia story, uses steam under fifteen different pressures within a single cylinder the size of a nail keo and the model exhibited generates 25 H. P. and makes 3,000 rey S nae . : j i olutions a minute alm without vibration, It is announced, furthermore, and with great em ha sis, that the turbine uses about one-third the amount of steam requited to run an ordinary engine. The story says that with this new power steamships;can cross the ocean in three days.
