Nelson’s Lubricating Cup
The importance of the proper lubrication of moving machinery cannot possibly be overestimated. The results are twofold: first, the saving of power by the reduction of friction; second, the preservation of the machinery, which, by a neglect of this precaution, may be injured to such a degree as to call for constant repair and even result in the injured parts.
It is therefore that any device securing this requisite deserves serious attention. The patent top lubricator cup of Nelson, Finkel & Co., of No. 439 East Tenth Street, in this city, represented in our figure, strikes us as a very ingenious arrangement to accomplish this purpose. It consists of a cup or chamber A for receiving and holding the lubricant ; B, the valve which closes the aperture through which the lubricant is discharged from the cup and to the steam-chest or cylinder; C, the stopper or cover for closing the opening at the top of cup; D, the seat for stopper, which is a ring of compressible packing, known as the “Jenkins Patent Packing." (Duplicates of which can be always supplied.) In case of emergency, the manner of application is such that any ordinary packing—such as vulcanized rubber, cork, leather, cloth, paper, or braided gasket of lamp-wick, can be used successfully for the same purpose; E, the screw cap or compressor, which, when screwed down, carries with it the stopper until it bears on the packing-ring sufficiently to form a tight joint over the top of the cup, thereby preventing all egress from the top of the cup; F, the screw-shank, provided for the purpose of attaching the lubricator cup to the steam-chest, pipe, or cylinder; G, the vent opening; H and I, wood handles.
The manufacturers of this cup, with commendable modesty, do not claim that it is self-acting, nor that it purifies the oil or lubricating matter which it may contain; neither do they assert that it increases the power or saves ninety-nine per cent of the cost of running the engine.
No such wonderful qualities are claimed, but only the reasonable guarantee is given that the cup, when filled, will hold the requisite amount of lubricant, confining it in such a way that the egress is only to the steam-chest, pipes, or cylinder to which the cup may be attached. Its feed may be regulated at will; it is durable, and those parts which are subjected to wear are very easily repaired. In fact, this humble but important adjunct to the steam engine fulfills all the fundamental conditions required. The excellence of its workmanship as well as of all the productions of the above - mentioned firm, is guaranteed by the long experience of the senior partner, a gentleman for many years connected with the Novelty Iron Works in this city.
These cups are manufactured in seven sizes, varying in outside diameter from 1¼ to 5 inches, and in price from $4.75 to $25 each.
