Filed May 13, 1892. Serial No. 432,855. Claim: Ina water tube boiler, the combination, with a steam drum sustained above a furnace, and a distributing drum arranged at one side of the fire box, of a series of headers projecting upward from such distrib- uting drum a series of ascending water tubes projected from the face of each header inward over the fire and thence upward through the furnace into the bottom of the steam drum, a series of descending water tubes shielded from the furnace and connecting the side of the steam drum with the upper part of the header, and a partition extended downward within the header between the inlet of such descending tube and the lower ends of the ascending tubes. 520,823 BOAT.

WATER-TUBE BOILER. ba [da 4K | 520,823. BOAR 520.944. PADDLE-WHEEL MECHAN: é = on : NW Financial Scheme of the New Canadian Line. Papers in connection with the proposed fast Atlantic service were pre- sented to the Canadian parliament today. They show that Mr. Huddart's proposal is to float a company with a capital of 42,000,000 sterling, which shall jointly operate the Atlantic and Pacific services, Four vessels of a tonnage of 8,000 to 10,000 tons are to be placed on the Atlantic witha speed of 20 knots an hour. Two new vessels are to be added to the Pacific service, the subsidy for which will remain at $125,000. The Atlantic sub- sidy is to be $750,000 yearly. Ifthe scheme now proposed goes through, the Dominion government will agree to guarantee the interest on a deben- ture issue of £1,500,000 at 4 per cent. for 20 years, and to renew the con- tract at the end of ten years, both conditions being contingent on the ser- vice being satisfactory to the government. Inu reply to a query from Mr. Bowell, Mr. Huddart cabled that the proposed steamers for the Atlantic service. would have acold storage capacity for 4,000 quarters of beef in chilled condition, equal to 1,000 head of cattle. Presentation to the Chief of Transportation. The association of American exhibitors of the World's Columbian exposition presented to Willard A. Smith, chief of the transportation de- partment a handsome vase of Greek design at the Union League club, Chicago, last week. The vase stands 25 inches high, on an ebony pedestal. The chief feature is the reproduction of the golden door in relief. En- Ist a C in said middle section, a stern section provided at its forward end with a groove, adapted to receive the bead on the rear end of the middle sec- tion, and sockets adapted to receive the pins at the rear end of the middle section, and a gasket attached to the stern section and extending across the groove in the end thereof. , 620,944. PADDLE-WHEEL MECHANISM FOR PROPELLING ABOAT. Joseph C. Thomas, New Bedford. Mass. Filed Jan. 22, 1894. Seriai No. 497,616. Claim: A boat propelling aparatus, mounted on a base, adapted to rest across the gunwales of a boat, and be removably secured thereto, consisting of the paddle wheels a', mounted on independent shafts a, the sleeves 62, one on each shaft, provided with bevel gears 4, and adapted to be shifted longitudinally on said shafts, and to revolve therewith; the gears c, and c', mounted on shafts, having their bearings in stands c',; a shaft d, mounted in bearings, and bearing bevel gears d', d', adapted to mesh with the gears c', and provided with the chain or band wheel aaa shaft e, mounted in bearings f, and provided with cranks e*, anda chain, or band wheel ¢', connected with the wheel d* on the shaft d, by a chain or band. 521,146. PROPELLING MECHANISM FOR CANAL BOAT. Henry W. Hildebrand, Denver, Colo. Filed December 11, 1893. Serial No. 493,302. Claim: The combination witha boom attached to the boat, of a trolley carried by the boom and composed of a weighted lever, two shafts journaled in the lever and carrying pulleys adapted to engage a suitable fast cable, both above and below, fast gears mounted on the pulley shafts and adapted to mesh, and suitable means connected with the boom for transmitting motion from a prime motor on the boat to the trolley. circling the vase upon the upper hemisphere are eight medallions illus- trating the development of marine transportation. The series relating to propulsion by oar begins withthe primitive canoe of the aboriginee. Next the canoe is the Venetian gondola, whose silhouette, picturesque in outline, recalls pleasant hours the beautiful lagoons and waterways of Jackson park. Adjoining the gondola is the Viking ship in which each oarsman is shown seated behind a shield, recalling early methods of war- fare and the pre-columbian discoverers of America. Vessels with sails are represented by the Santa Maria; and the mind reverts to the models of the caravels, exact reproductions of the original ships and faithful in every detail of construction. A full rigged American sailing ship of the year 1800, the type around which cluster so many reminiscences of the beginning of American commerce and the early merchantmen and navy - of the United States, during the era of wooden bottoms, finds a place next the Santa Maria. The beginnings of the era of steam are recalled by the illustration of the first vessel ever propelled by a steam driven screw, upon the waters of any country--the twin screw steamboat invented and constructed in America by an American, John Stevens, 1804. The original engines were exhibited in the gallery of the transportation building. Fulton's steam- boat, the Clermont of 1807 is next, and following is the side-wheel trans- atlantic steamship which was the queen of the seas until 1840, while upon the ebony base will be found in carved ivory a graphic representation of the highest type of the fast transatlantic liner of 1893. THE LUCANIA now excels all records of ocean steaming in having made the round trip from New York and back again at an average speed of 2134 knots per hour over a distance of 5,784 knots.
