IMPROVEMENT IN LUBRIOATORS.

Specification forming part of Letters Patent No. 44,005, dated August 30, 1864.

To all whom it may concern:

Be it known that 1, LEWIS LEIGH, of Seymour, in the county of New Haven and State plied to use a certain Improvement in Lubrielare the following to be a full, clear, and exact description ot' the same, reference being had to the annexed drawings, making part ot' this specification, whereinp Figure 1 is a vertical section of my improved lubrieator as applied to a spindle that passes through a globular bolster, and Fig. 2 is a similar view of my lubricator as applied to a vertical shaft or rod passing through an ordinary bearing.

Similar marks of reference denote the same parts.

Great difficulty has heretofore been experienced in lubricating the vertical spindles in spinning machinery, vertical shafts, and sliding rods, in consequence of the oil ruiming down through the bearing or bolster ard the parts speedily becoming dry, causing wear and friction; and with spindles in spinningirames the velocity is so great that the centrifugal force prevents the oil from passing down through the bolster, rendering it necessary to stop the machine, sometimes twice aday, for the oil to pass down into the bolster.

The nature of my said invention consists in an oil-vessel provided with a horizontal or nearly horizontal conductor containing a capillary wick, in combination with a pipe-shaped globular bolster, so that the end of said conv ductor retains said bolster in its place, and the wick comes vin contact with the spindle, shaft, orrod to be oiled about the middle of the bearing, and supplies thereto the lubricating inaterial in a gradual manner, only the amount i necessary for the same being supplied from i time to time. Thereby waste of oil by it runi ning down the spindle or shaft is avoided, and but little attention is required to such spindles or shafts, because the oil-vessel only requires to be occasionally replenished.

In the drawings, (tis a journal box orbearing of any suitable kind, taking the lower end of the shaft b, and c is a bolsterforlued as a pipe surrounding b, and with globular collar setting within the bearing d. This globular and pipe bolster, however, is not my invention.

e is a reservoir or oil-vessel, ofsuitable size, at the top of which is a supply-hole, b, and from the side thereot'extends an oil-conductor, g, running horizontally or nearly horizontally and terminating near the side of the shaft, spindle, or rod to be oiled. This conductor is formed with a screw-thread around it, taking a tln'e 1d in d, whereby the lubricator is attached. This conductor g contains a cotton or other capillary wick, which prevents the oil escaping too quickly, and remains sufficiently saturated for lubricating the vertical spindle or shaft until the oil is exhausted from the vessel c.

The lubricater shown in Fig. 2 is the same as that in Fig. 1, but the shaft or spindle bis represented in Fig. 2 without the bolster. The operation ot' lubricating will be the same in both instances, but in Fig. l the end of the conductor answers the additional purpose of preventing the spindle-bolster from turning.

Ido not claim, broadly, a lubricator containing a capillary wiel( but What I claim, and desire to secure by Letters Patent, is-

The combination of the said lubricator with the pi pe-shaped globular bolster c, for the purposes and as specified.

In witness whereof I have hereunto set my signa-ture this 27th day of November, A. D. 1863.

LEWIS LEIGII.
