EMPROVEMENT IN LUBRICATORS.

Specifioation forming part of Letters Patent No. 50,719, dated Qctohel 31, 1865.

T0 aZZ whom it may concern:

Beit known that I, S. E. KLEINSOHMIDT, of

Clevela-nd, in the county of Ouyahoga and State of Ohio, ha"e invented certain new and useful Improvement-s in Uil-Cups; andI do hereby declare that the following is a full and com plete description of the construction and operation of the Same, reference being had to the accompanying drawings, making a part of this speoification, in whioh Figure 1 is a perspeotxe view of the cup. Fig. 2 is a "ertical section.

Like letters of reference refer to 1ike parts in the views.

The oil-cup is made in two sections, A and B, formed as represented, and united by a screwjoint at 1), or it may be otherwise c0n structed, so as to be adapted to the purpose for which it is designed. The enlarged por ti0n C is an oil-chamber. From this chamber to the mouth A is an orifioe or opening, d.

Below the oil-chamber, and communioating with the maohinery to be lubricated with oil, are orifices or openings 9 and h. The orfice 9 is extended up till near the top of the oilcharnber by a tube, g, which is one side of the opening d fron1 above. The orifices d, and h above and below the eha1nber extend through the plugs E and F of the faucets E and Fwhen the faucets are ina certan position, as represented, and by means of which the orifices are closed by turning the faucets in the ordinary mannen The practical benefits resulting from an oiloap constructed with two orifices below the oilchamber, one extending up, as descrbed, are as fo1lows: The oil-cup being in its position on the machine 0r steam-chamber, the faucet F must be turned so as to close the orifices 9 and h, shutting ofi the steam from below, and the aucet E turned so as to open the orfice d, when, by pouring the oil into the mouth A, it runs down into the chamber 0, and when the required amount of oil is in the chamber, the faucet E must be turned, closing the orifice d.

The faucet F is then adjusted so as to open the orifices 7 and h, when the oil Wil1 run down the orifice 7zand the steam wi1l rise in the orifice and pass out at the top of the tube g, filling up the ohamber O above the oil.

In the first place, when the orifices 9 and h are first opened, the steam will rise principally in the orifice g, for the oil Will be running down in the orifice h, and the pressure of the oil wi1l prevent the steam from rushing up, as it does in the other orifice; and then the chamber above the oil is soon filled with steam, which oauses an equilibriurn, or the pressure of steam will oe equal, and the oil wl1 run down by its own weight. The orfice g acts as a vent to relieve the orifice h from-the pressure of the steam, and thus allow the oil to pass freely down. \Vhere there is but one or ifice be1ow the chamber,when the oil runs down out of the chamber, a partial vacuum is formed above, and the pressure of steam fron1 below being so great, it retards very 1nuch the descent or flow of the oil, forcing it out more or 1ess through the joints of the cup; but by the two orifices the charnber is filled With steam, the steam occupying the space occupied by the displace.

ment of the oil as it runs out. The displace ment of the oil being thus entirely taken up by steam risiug through the orifice g, causes the oil to flow most freely through the orifice h onto the mechanism.

What I claim as n1y rnprovement, and de S. E. KLEINSCHMIDT.
