20 MARINE REVIEW. [March 29, MANZEL AUTOMATIC OIL PUMP. The accompanying illustrations show a recently improved form of oil feed pump which offers some advantages not possessed by others now in the market. The pump is constructed of brass, finished and nickel plated all over. The reservoirs and sight feeds are of glass and the adjustment of OIL FILLER & STRAINER FIG. 1.

One strong feature of this pump is the variable feeding of oil and the independ- ently adjusted flow of oil from the reservoir on the larger sizes of pump. We show a single and also a triple feed among the illustrations. In this triple feed it will be seen that there are three separate pumps con- nected to the reservoir and having all the plungers yoked to be oper- ated by one ratchet. This furnishes a varying or uniform supply of oil as desired, independently of the stroke of the plungers, which is also ad- justable, as will be readily under- stood from the illustration. The sight feed forms an important im- provement in this class of machin- ery, as it insures instant detection should the reservoir become clogged from dirty or gummy oil. The pump cylinder is closed by a ball check valve, held in place by a spring, as shown in the engraving of the single pump. The reciprocating motion is changed to rotary by a ball clutch which is shown in Figs. 3 and 4. Fig. 3 shows an annular groove on the inside of the periphery of th wheel and a similar groove on the corresponding face of the clutch piece, carried on the oscillating arm, with the ball held in place by a spring. Fig. 4 shows the brake, which is the same _ construction, reversed and applied to the hub of the driving wheel. Therefore the brake holds SIGHT FEED y ol FILLER REGULATING VALVES a & STRAINER CONNECTING ROD COUPLNG FIG 2. TRIPLE FEED MANZEL OIL PUMP. KIG. 8. BALI.

They are in use on the steamer Geo, Spencer, on the Hingston & Woods dredge Pan American, on vessels of the Tonawanda Iron & Steel Co., at the Carnegie Steel Works, Pittsburg, and also by the Deering Harvester Co. of Chicago, Cummings Cement Co. of Akron, W. J. Rainey of Mt. Braddock, Pa., Buffalo News, Snow Steam Pump Works and many others. In all cases they are giving satisfaction. A descriptive circular issued by the manufacturers, Manzel Bros., No. 87 Van Rensselaer street, Buffalo, says: "As our modern engines and pumps require perfect cylinder lubrication to enable them to reach their highest efficiency, this lubricating oil pump has been especially designed to meet the demand for more reliable and economical lubrication of steam engines and pumps _ of every description. It is noiseless in operation; it has no equal on high speed engines; sight feed is free from steam and water; it will feed any kind of oil or graphite; varia- tions of temperatures do not effect its operation; it will save from 30 to 60 per cent. of oil." The Tonawanda Iron & Steel Co. of North Tonawanda, N. Y., re- ports in a letter to Manzel Bros.: "Our superintendent, Mr. Kerr, says that your pumps give the best satis- faction of any pumps he has ever used." Schoellkopf, Hartford & Hanna Co. say: "We have two of your cyl- inder oil pumps in practical use and both appear to be giving excellent satisfaction. We shall order more of these as our needs may require them." Peter Eckam, chief engineer of the Buffalo Brewing Co., also recommends this pump very highly. He says: "I have been using one of your automatic oil pumps on a high- speed engine for some time. I can recommend them as the best that are made. In the saving of oil they have no equal. The sight feed is very desirable." All pumps have a hand attachment on driving wheel; may be used before starting engine, or if more oil is needed momentarily. It does not disturb adjustment. FIG. 4.

The Review has received from the Marine Iron Works, Station A, Chicago, a pamphlet bearing the above heading and designed to furnish information to those who, without previous experience, are thinking of purchasing or building and operating river steamers on shallow and swift streams. It reviews ina general way the necessary qualities of design and construction that must be considered in suiting the boat to the conditions required of it, and some of it is so pertinent that we quote the following: "The facts are that designs and plans of construction of the hulls and equipment of these boats may fairly differ from each other quite material- ly, although each may be best in its particular type for certain waters and conditions. Unfortunately, however, it too often occurs that some one successful boat is adopted as a pattern where the work and conditions of service are radically different from that which the original boat is per- forming successfully. Suppose a small steamboat is required for a river, which is not only very shallow, but also has a rapid current, crooked channel, and boat required to make sharp and quick turns in its regular duty as a fast passenger beat. Suppose, also, that the same size of boat _is wanted for another river which, however, has a fairly straight, clear channel, moderate current, and boat must do some towing. The two boats, as far as design or 'modeling' of hull and equipment is concerned, should be entirely different to secure the best results sought for in each case, and each of the two prove a source of satisfaction and profit to their owners, whereas if their positions were reversed they would both fall short of oe showing to a degree difficult for the owners to under- stand. "Manifestly a 'cure-all plan' of design, construction and equipment which might now and then accidently hit the mark, would be very likel: to miss it nine times out of ten, and is our reason for emphasizing the well-tested fact that in every case, without exception in river navigation, the boat must be designed, built and fitted out to meet the exact and ofttimes peculiar requirements of each particular case in order to be successful. "Tt is the completeness and correct combination of the machinery and et ceteras that go a long way toward making a successful steamboat. We have found it necessary to design and make most of the accessories and deck equipment for our outfits of driving machinery or boats, in order that each article, fitting, etc., would fit the case and prove suitable for the most severe work or strain that it may fairly be called upon to perform. In comparing estimates of costs and quotations, do not underestimate the value of completeness as well also the character of work, having in mind the fact that the difference in price can only be saved once." The pamphlet gives full details as how to order a boat for special purposes and explains the company's-plan of building boats and shipping them "knocked down" to save freight and allow of easy transportation away from railroads, etc. It also explains how they build machinery only and furnish plans for building the boats on the waters on which they are to operate. The company has been very successful in this work and many of its boats are now in successful operation in Mexico, the South Ameri- can republics, the Congo country in Africa and many of the western lakes and rivers of America. Copies of "River Navigation" will be mailed free on application from those interested. It is reported in New York that a $50,000,000 syndicate, of which J. N. Huston, ex-treasurer of the United States, is the head, has taken up the work of constructing a canal across the Bayonne peninsula from New York bay to Newark 'bay and thence to South Newark, N. J. The new company has acquired the New York and Newark bay ship canal, which was incorporated in New Jersey thirty-four years ago. The plans con- template the possible accommodation of 100 steamers at one time within the piers and basins jutting into New York harbor.
