70 terial, the operation being completed quickly and accurately. A pan, at- tached to the under side of the table, catches the cuttings and keeps the shop in a neat condition. The table of the machine is provided with a quadrant stop that can be set to any angle within the sweep of the saw blade used. The proper alignment of the pul- leys obtained by having the motor HIGH SPEED METAL CUT-OFF SAW SHOWING I-BEAM IN PLACE READY TO BE CUT keyed to the base, the handwheel providing for the convenient belt ad- justment, and the lower belt tension provided through a wider belt are other features of the design of this machine. 2 Adequate protection to the opera- tor is provided by means of steel guards that cover the belt and saw. Belge are Bridge | (Continued from Page 35) bered that each cable has 18,666 wires, that each is 3540 feet long and weighs 6,750,000 pounds, this task of weaving the cables in place was prodigious. More so, perhaps, when it is realized that the laying of the strands and the weaving of the cable had to be done in such a manner that not a single wire should shirk its strain, thus throwing added bur- den on another wire. That this was done, and done per- fectly, however, was assured by Chief Engineer Modjeski when he said: “In such work there is always the dan- ger of a wire or two slipping and the accident not being discovered un- til we come to the squeezing process with the ‘traveling spider.’ Not one wire, however, has failed to fall into its intended place and the contrac- tor is to be congratulated on the performance of the work of his wire- men. All wires pull together.” MARINE REVIEW The suspender ropes supplied by the American Cable Co. and extending from the two main cables to the floor of the bridge, number 596. These alone have a total weight of 7400 tons. The floor which they support is made of steel and reinforced concrete, there being on it two 10-foot sidewalks, a 57-foot motor drive, two trolley tracks and two rapid transit tracks. Suspension bridges date back to the obscurity of Chinese history. The first mention of suspension bridges was made by Kircherns in his “China Illustrata” published in 1667 wherein he describes a suspension bridge con- sisting of 20 chains, which, according to him, had already seen more than a century of service. Among the earlier suspension bridges is the one over the Danube at Budapest which has a span of 666 feet, and the Clifton bridge at Bristol, England, having a span of 702 feet. Both of these bridges, however, are of chain. It remained for Philadelphia, in 1816, to erect the first wire-cable suspension bridge across the falls of Schuylkill thus ushering in a far-reaching de- velopment in bridge construction and then to complete what she had started with the erection of the Delaware bridge, which will take its place im- mediately as the principal factor in the future growth and development of the two cities and surrounding territory. Recent Sales of Ships T. V. O’Connor, chairman of the United States shipping board has announced the following sales of gov- ernment tonnage. J. M. CONNELLY, SHARON and BESSEMER, steel tankers each of 7057 deadweight tons, to the Atlantic Refining Co., Philadelphia for the sum of $40,000 each, ‘‘as is’ and ‘‘where is,’ for diesel conversion. At the time of the sale these tankers were laid up at Mobile, Ala. The Atlantic Refining Co. will convert these vessels to diesel electric drive, it is un- derstood, quite similar to the J. W. Van DYKE, in which three Ingersol-Rand oil engine generating sets were installed for the main motive power which is applied to a single mo- tor driving the propeller. HAITI, a steel cargo vessel of the deep draft lake-built type to the Columbia Steamship Co., subject to approval by the legal department, for $10,000 cash “‘as is’ and ‘“‘where is,” subject to a five year guarantee of service of nine voy- ages per annum to the Virgin islands, British and French West Indies, Paramaribo and Dutch Guiana. World Markets BERKUT, single deck steamship, 6550 dead- weight tons, 4415 gross tons, to French buyers. FRANCISCA, single deck steamship, 1289 net tons, 2115 gross tons, to Italian buyers. LAKE FARIBAULT, single deck steamship, 4115 deadweight tons, 2603 gross tons, for $25,000 to Industrie Navali Soc. Anon., Genoa. MoprEsta, single deck steamship, 6250 dead- weight tons, 38868 gross tons, for about £30,000 to buyers not stated. NICOLAOS, single deck steamship, 5955 dead- weight tons, 38844 gross tons, for about £16,500 to Greek buyers. Ronpo, single deck steamship, (renamed GLUCKAUF). 2750 deadweight tons, 1906 gross tons, for about £15,000 to Gluckauf Kohlen- handels G. m. b. H., Rostock. UswortH, single deck steamship, 8000 dead- weight tons, 1985 gross tons to the Nigerian government. July, 1926 Standardized Building of Harbor Craft The following announcement was is- sued recently from the office of Law- rence R. Wilder, president of the American Brown Boveri Electric Corp. ’ With the award last week, of two contracts aggregating $3,479,000 to the American Brown Boveri Electric Corp., Camden, N. J.; one for 33 pa- trol boats at $638,000, each for the United States coast guard service and the other for 6 diesel electric ferries at $233,333 each; the corporation named is inaugurating a unique ac- tivity in standardized ship building which will be carried on in addition to its established business in built-to- order ships and smaller craft. In this department there will be designed, built and placed in stock, standardized smaller craft and har- bor improvement units under the vari- ous classified services beginning with ferries, yachts, car floats, dredges, barges, and scows. The prospective purchaser will thus, in a short time be able to virtually step into the ship yard and pick out the type and size of floating unit he desires and gain at once the advantage of quick de- livery, and exact visualization of what he is buying without the beclouding medium of rough sketches and the ad- vantage of one profit manufacture on a production basis available to him now only in the purchase of such every day items as automobiles, motor boats, etc. A great latitude is still retained for the purchaser in a choice of powering details and outside fit- tings and finish but by the standardi- zation of main parts the best avail- able composite engineering experience is embodied and this without the sac- rifice of the ever important factor of price and delivery. Joins Operating Staff John Rae has resigned from the Munson line to join the Huasteca Pe- troleum Co., 120 Broadway, New York City, which is the operating department of the Pan American Pe- troleum and Transport Co. Mr. Rae is one of the best known tanker men in the country and his many marine friends wish him success in his new connection. Mr. Rae was with the Standard Oil Co. of New Jersey for several years as assistant to the manager of the marine department and left that or- ganization to join the Tidewater Oil Co. in a similar position. He left the Tidewater Oil Co. two years ago to join the Munson line and has been with them up to the present time.
