37 ig MARINE REVIEW PATENT SHIP’S BRAKE Liverpool, Feb 11.—A good deal of attention is being given in Liverpool shipping circles to an invention of Mr. Henry Simp- son for rapidly checking the way on a ship, which is very properly described as a ship’s brake. A model of a ship is being exhibited on the Shipping Exchange for the purpose of illustrating the working of the patent, and the advantages it possesses of more quickly stopping steamers. The patentee states that the object of the invention is to meet the want which has arisen, and in the near future will be much felt, of some method of quickly stopping a steater’s way to avoid stranding or collision. A syndicate is being formed to acquire and fit up a small steamer about 70 ft. long for the purpose of demonstrating on a commercial scale the efficiency of the brake. The apparatus consists of several pairs of buoyant wings or vanes worked horizontally in suitable cham- bers, one behind the other, on each side of the bow of the vessel below the water line, the arrangement being symmetrical with respect to the center line of the vessel. A hinged and buoyant door is placed before each vane to admit a free flow of water when the brake is in operation. The total length of the vanes is about equal to the ship’s beam, and their breadth is about equal to half the ship’s draught. The number, positions, and propor- tions of the vanes may be modified as desired. The “arresters” are so constructed that they loosely fit and fill up the openings, so that when the apparatus is not in use, the external appear- ance of the bow, and the resistence to its passing througn the water, are similar to that of a vessel not so fitted. The vanes are triangular in form and are attached at their centers to vertical spindles, so that all can be freely revolved for about a quarter of a circle until their faces lie at right angles to the center line of the vessel. Large flat surfaces are thus opposed to the water, and present a very great resistance to the passage of the vessei through it, and being almost balanced in all positions. The brake may be put in action, or out of action, when the vessel is going full speed. The revolution of the vanes is accomplished by means of levers or cranks, and can be operated in any direction from the bridge or elsewhere as desired. One movement of the hand may put the brake in action, or two levers may be provided, one controlling the port, and. the other the starboard side. The strength of the bow lost at the openings is compensated for bv in- troducing strong steel decks, both above and below, as well as between the vanes. The total resistance may be taken as about one thousand tons on a 25-knot steamship of 70-ft. beam. The structural strength of the brake is such that it would carry a much greater load than this with safety. When the brake is in use, the water flows freely around and behind each vane or arrester, thus insuring efficiency of action. The apparatus can be brought into action instantly, while a vessel is going at full speed, and being entirely independent of the main engines, can be made to act with maximum efficiency some time before. it Steamships, Government, Revenue and Lighthouse Vessels, Yachts and Boats of all descriptions FURNISHINGS “From Steerage to Gaptain’s Gabin.”’ Govering everything that can possibly be required in Furniture, Galley Ranges, Beds, Galley Utensils, Garpets and Rugs, | Monogram and Upholsteries, Grested Linens, Bedding, Ghina and Groceries, Glassware, etc. Detailed work requfring special plans or sketches carried out by expert operators. 5 _ We gladly submit Estimates free of charge.

Either port starboard brakes may be put in action, and prove of great assist. ance in steering quickly in case of emergency, or when the vessel is going dead slow, and does not readily answer her helm. -The invention is claimed to possess the following advantages: Buoy- ancy of working parts, great strength of structure, great power Patent Ship’s Brake. of resistance, ship’s lines not altered, ease of working when the vessel is going at full. speed, no jerk or shock when used, and under immediate control of the commander from the bridge. It — is calculated that a vessel fitted with the brake would slow in one © length, and stop in about two lengths. It is also claimed for this ship’s brake that it would save the main engines from being injured by sudden strains in reversing, prevent many strandings and collisions, save much life and valuable property, reduce fisks and with them the insurance premiums, and lead to greater confidence in and patroriage of vessels so fitted. Mr. P. H. Wilhelm, formerly representing the New York Car Coupler Co., Washburn Car Coupler Co., The Buckeye Mal- leable Iron & Coupler Co., The Railroad Supply Co. of Chicago, with headquarters at Atlanta, Ga. has accepted a position as — railroad representative of the American Steam Gauge & Valve Mfg. Co., Boston, Mass., with branch offices at New York, Chi- cago, Philadelphia and Atlanta, Ga. Mr. Wilhelm has spent the greater portion of his life in the actual railroad service and it will be remembered that, in 1893, he was, on the recommendation of the majority of the railroads, appointed division superintend- — ent of transportation at the world’s fair in Chicago. After the © close of that exposition he took up the active business of railroad supplies; which he has followed up to the present time. Mr. Wil- helm has been very prominently mentioned for the position of superintendent of transportation at the St. Louis exposition, but prefers to remain in the active railroad supply business. The American Steam Gauge & Valve Mfg. Co. now have the largest plant in the country devoted to the manufacture of steam an and other gauges, safety valves, steam engine indicators, whistles and steam supplies in general, and, being the oldest house in thts conutry in their particular line, Mr. Wilhelm will certainly be able to keep up his reputation of representing one of the best houses in the country. ’ “Seaboard Steel Castings” A Guarantee of Quality.
